Hola amigos de la red, DERMAGIC de nuevo con ustedes, el tema de este mes: LA DERMATITIS SEBORREICA, enfermedad bastante común hoy en día. Relacionada con el HONGO PITYROSPORUM, y también al cotidiano STRESS, luz solar y la temperatura corporal (18). 

Me motivo hacer la revisión el hecho de que en el CONGRESO ANUAL de la Academia Americana de Dermatología, se hablase con insistencia del uso con ÉXITO del ITRACONAZOLE en el tratamiento de esta enfermedad. En mi viaje por la red encontré que este USO no es TAN NUEVO, de hecho encontré una referencia que data del año 1.985 (15). La mas reciente del año 2.000 (14), un estudio que se hizo sobre BLEFARITIS SEBORREICA donde se uso con éxito esta medicina. 

El uso de Los antimicóticos en la DERMATITIS SEBORREICA data de los años 80 cuando se describió la relación de esta con el HONGO Pytirosporum (malassezia). habiéndose usado con éxito, también el ketoconazole, fluconazole, bifinazole y también la TERBINAFINA. Con respecto a esta ultima, personalmente la he usado en 2 casos de DERMATITIS SEBORREICA FACIAL con un resultado altamente satisfactorio. 

Otros alternativas utilizadas con buenos resultados en la dermatitis seborreica son: 

El metronidazole, la urea, propilenglicol, ditranol. biotina, vitamina-complejo B, succinato de litio, 
glicerina, tacalcitol, L-dopa, peróxido de benzoilo, esteroides tópicos, foto y foto quimioterapia, pitirionato de zinc, terbinafina en solución, sulfuro de selenio, sulfacetamida sódica tópica y otros. 

En estas 90 referencias los hechos, espero las disfruten. 


Saludos a todos...

Hello friends of the net, DERMAGIC again with you, the topic of this month: THE SEBORRHEIC DERMATITIS, illness quite common today in day. Illness related with the YEAST PITYROSPORUM, and also to the daily STRESS, solar light and the corporal temperature (18). 
I motivate myself to make the revision the fact that in the ANNUAL CONGRESS of the American Academy of Dermatology, speaks with insistence of the use with SUCCESS of the ITRACONAZOLE in the treatment of this illness. In my trip for the net found that this USE is not SO NEW, in fact I found a reference that dates of the year 1.985 (15). The but recent of the year 2.000 (14), a study that was made on SEBORRHOEIC BLEPHARITIS where use with success this medicine. 

The use of the anti- mycotics in the SEBORRHEIC DERMATITIS dates of the eighties when the relationship of this was described with the yeast pytirosporum (malassezia). there being used with success, also the ketoconazole, fluconazole, bifinazole and also the TERBINAFINE. With regard to this, personally I have used it in 2 cases of FACIAL SEBORRHEIC DERMATITIS with a highly satisfactory result. 

Other alternative ones used with good results in the seborrheic dermatitis are: 

The metronidazole, the urea, propilene-glycol, dithranol. biotin, vitamin-complex B, lithium succinate,

Objective: To evaluate the role of topical metronidazole gel in the treatment of seborrheic dermatitis. Methods: Forty-four patients with seborrheic dermatitis were enrolled in the study. All topical treatments were stopped for at least 2 weeks before the patients were allocated at random to receive either metronidazole 1% gel or placebo for 8 weeks. The severity score was measured at the initial evaluation, and the patients were followed up at 2-week intervals for 8 weeks. A global evaluation of improvement was done at 8 weeks. Results: Thirty-eight patients completed the study; 21 patients in the metronidazole group and 17 patients in the placebo group could be evaluated. There was a statistically significant decrease of the mean score even at week 2; the difference became highly significant at 8 weeks (p < 0.001). On the final evaluation at 8 weeks, 14 patients in the metronidazole group showed marked improvement to complete clearance as compared to only 2 patients having moderate improvement in the placebo group (p < 0.001). Conclusion: The present trial has demonstrated the effectiveness of topical 1% metronidazole gel in seborrheic dermatitis. Copyright 2001 S. Karger AG, Basel

Seborrhoeic dermatitis is a common polyaethiological chronic disease affecting mainly the skin of face and scalp. The paper informs about aetiopathogenetic factors and clinical signs of SD. It review the contemporary methods of both external and internal treatments. Topical antimycotic treatment focused on Pityrosporum ovale, which could be the main causative agent, is considered to be the most important approach.

BACKGROUND: Cutaneous infections induced by Malassezia ovalis (Pityrosporum ovale) represent a therapeutic problem due to the high rate of recurrence. OBJECTIVE: We studied feasible strategies to control the growth of M. ovalis, compatible with topical use in cosmetic formulations. Studies were performed on the effects of pH, ionic strength, cinnamic acid and related compounds on mycotic growth. METHODS: M. ovalis was cultivated in modified Sabouraud agar. The effects of pH, ionic strength and cinnamic acid and related compounds on mycotic growth were studied by the membrane filter method. RESULTS: In vitro growth of M. ovalis is strongly affected by pH and ionic strength. pH 4.5 induced a growth inhibition of about 95% and 1 M NaCl, at the optimal growth pH, reduced cell growth by over 90%. Cinnamic acid showed an inhibitory effect of 50% at 0.005 g/dl; 30 min incubation with cinnamic acid 0.5 g/dl had a mycocidic effect. CONCLUSION: These results suggest the use of cosmetic compositions containing cinnamic acid or buffered acidic lotions and shampoos in the treatment of M. ovalis infections of the scalp, eventually in addition or alternative to antimycotic drugs or in maintenance therapy. Cosmetic formulations with high ionic strength or skin irritant derivatives such as cinnamaldehyde cannot be proposed for practical use. Copyright 2000 S. Karger AG, Basel

BACKGROUND: Seborrhoeic dermatitis is a common papulosquamous dermatosis affecting 2-10% of the adult population. Current treatment options are limited and not always satisfactory. Objectives We aimed to investigate the efficacy of narrow-band ultraviolet (UV) B (TL-01) phototherapy as an alternative treatment for seborrhoeic dermatitis. METHODS: Eighteen patients with severe disease were enrolled in an open prospective study. Treatment was given three times weekly until complete clearing or to a maximum of 8 weeks. A clinical score assessing erythema, scaling, infiltration and pruritus was performed at baseline and every 2 weeks thereafter. Additionally, the patients were asked to rate the intensity of pruritus on a visual analogue scale. After completion of the study the patients were followed up to determine the median time interval until recurrence. RESULTS: All patients responded favourably to treatment, with six showing complete clearance and 12 marked improvement. The median clinical score decreased from 7.5 (range 4-8) at baseline to 0.5 (range 0-3) after 8 weeks of treatment (P = 0.005). The median pruritus score decreased from 4.5 (range 0-8) at baseline to 0 (range 0-3) at week 8 (P = 0.008). Relapses occurred in all patients after a median of 21 days (range 12-40). No side-effects of treatment were observed except occasional episodes of a moderate erythemal response. CONCLUSIONS: Narrow-band UVB phototherapy appears to be a very effective and safe treatment option for patients with severe seborrhoeic dermatitis.

A 71-year-old woman visited our clinic due to the presence of widespread scaly erythema on her face, scalp, and lower extremities. She was tentatively diagnosed as having seborrheic dermatitis but the symptoms were difficult to distinguish from psoriasis vulgaris. As a result, she was diagnosed as having sebopsoriasis. She was treated topically with an active vitamin D3 compound, 1a-24 (R)-dihydroxycholecalciferol D3 (tacalcitol) cream. She applied tacalcitol cream twice daily for 4 weeks, and her facial eruptions thus cleared up completely. No recurrence was observed for 2 months thereafter, even though the use of tacalcitol cream was stopped. To investigate whether or not tacalcitol cream is generally effective for the treatment of such seborrheic dermatitis-like eruptions, three more patients were treated with tacalcitol cream. All patients exhibited scaly erythematous macules on the face and/or scalp, and their eruptions improved rapidly with tacalcitol cream. Tacalcitol cream was thus found to be effective and useful for the treatment of both sebopsoriasis and even seborrheic dermatitis of the face and scalp.

BACKGROUND: High incidence rates of seborrhoeic dermatitis (SD) have been reported in HIV-infected individuals, indicating immunosuppression to be involved in the pathogenesis. OBJECTIVE: To establish the prevalence of SD in mountain guides who have a high occupational exposure to solar UV radiation. PATIENTS AND METHODS: In November 1999, 283 mountain guides were physically examined on the face and scalp for symptoms of SD in Austria (n = 75), Switzerland (n = 123) and Germany (n = 85); they were 21.3-93.1 years of age (median age 41.4 years). RESULTS: Forty-six of 283 (16. 3%) mountain guides when examined clinically were found to have SD. The median age of mountain guides with SD was 41.2 years. There were similar incidence rates in all three countries. CONCLUSION: SD affects mountain guides in a clearly higher percentage as the general population. We suggest UV-induced immunosuppression due to occupational sun exposure as a pathogenetic factor. Copyright 2000 S. Karger AG, Basel

The disease commonly known as "dandruff" is caused by numerous host factors in conjunction with the normal flora yeast Malassezia furfur (Pityrosporum ovale). Indeed, clinical studies have shown that administration of antifungal agents correlates with an improved clinical condition. Almost all commercially available hair shampoos publicize that they contain some form of antifungal agent(s). However, few studies have been published in which antifungal activity of commercially available hair shampoos have been contrasted experimentally. In this study six commercially available shampoos (in the Philippines) were assessed for antifungal activity against a human (dandruff) isolate of M. furfur: (a) Head & Shoulders (Proctor & Gamble); (b) Gard Violet (Colgate-Palmolive); (c) Nizoral 1% (Janssen); (d) Nizoral 2% (Janssen); (e) Pantene Blue (Proctor & Gamble); and (f) Selsun Blue (Abbott). The results demonstrated that all six of the assayed hair shampoos have some antifungal effect on the test yeast. However, there was consider variation in potency of antifungal activity. Nizoral 1% and Nizoral 2% shampoo preparations were the most effective. The 1% Nizoral shampoo was consistently 10X better at killing yeast cells than the next closest rival shampoo. The 2% Nizoral shampoo was 10X better than the Nizoral 1% product and 100 times better than any of the other products assayed. The study demonstrated that shampoos containing a proven antifungal compound were the most effective in controlling the causative yeast.

Thirty strains of the lipophilic yeast Pityrosporum ovale were isolated from patients suffering from seborrhoeic dermatitis and dandruff and tested for susceptibility both to some classic antifungal agents and to several primarily non-antimycotic drugs. Minimal inhibitory concentrations (MIC) of altogether eleven agents were measured by the agar dilution technique. As expected, the tested imidazoles showed a good inhibition of growth of Pityrosporum. The most effective agents were ketoconazole (MIC 0.1 microgram/ml) and itraconazole (MIC 0.05 microgram/ml for some strains). MIC for fluconazole, clotrimazole and tioconazole were also low, indicating a good inhibition of Pityrosporum. In contrast, the range of MIC for bifonazole was moderate to high (for some strains 12.5-25 micrograms/ml). For zinc pyrithion a very good in vitro efficacy (MIC 0.78-1.56 micrograms/ml) was dedicated. The MIC for selenium disulphide was 1.56-3.13 micrograms/ml. The antipsoriatic drugs dithranol and liquor carbonis detergens also inhibited growth of all Pityrosporum ovale strains investigated but only at higher concentrations.

Pityrosporum ovale is a lipophilic yeast belonging to the normal human cutaneous flora in adults. It is not only a saprophyte but also an opportunistic pathogen associated with: Pityriasis versicolor, Pityrosporum folliculitis, seborrhoeic dermatitis and some forms of atopic dermatitis. Even systemic infections have been described. In pityriasis versicolor P. ovale change from the blastospore to the mycelial form under the influence of predisposing factors such as high temperature, high relative humidity or endogenous factors such as greasy skin, sweating, heredity, immunosuppressive treatment or disorders. Topical treatment is often effective but short term treatment with fluconazole, ketoconazole or itraconazole is also effective. The great problem is recurrence and to avoid this a prophylactic treatment is mandatory. Pityrosporum folliculitis is a chronic disease characterized by pruritic follicular papules and pustules located primarily on the upper trunk, neck and upper arms. Under the influence of the same predisposing factors as in pityriasis versicolor P. ovale increase in numbers in the hair follicles. The main differential diagnosis is acne vulgaris. The effect of antifungal treatment is often dramatic. There are now many studies indicating that P. ovale plays an important role in seborrhoeic dermatitis. Many of these are treatment studies showing a good effect of antimycotics parallelled by a reduction in number of P. ovale. Severe seborrhoeic dermatitis often difficult to treat is associated with AIDS. In a recent study we have evidence for a slight T-cell defect in many patients with seborrhoeic dermatitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Numerous AIDS patients show the typical seborrheic eczema in a very prominent way. For this is an inflammatory disease, combination preparations were taken frequently which contain antimycotics and corticosteroids. We investigated 7 antimycotic compounds in 3 inflammatory models: amorolfin, ciclopiroxolamine (cic), fluconazole, ketoconazole, miconazole, naftifine, and rilopirox. In an in vitro model the inflammatory activity towards the 5-lipoxygenase was investigated. 1,000 mumol naftifine, 100 mumol ketoconazole, 50 mumol cic, and 10 mumol rilopirox inhibited 5-HETE by 90%. In a cell culture model only cic had a significant activity towards cyclo-oxygenase. In this model the inhibition of the prostaglandin E2 liberation by 1 mumol cic was 40%. In an in vivo model the anti-inflammatory activity on a mouse ear was investigated (arachidonic acid induced). In this model only cic showed a significant inhibition of inflammation (50%) at 1 mg/ear. These investigations show, that cic has a strong antiphlogistic activity. In an open clinical trial with 20 patients suffering from seborrheic eczema after 4 weeks on cic cream a strong inhibition of infiltration and flakiness had been observed. The antimycotic compound cic offers a possibility to treat inflammatory mycoses without using corticosteroid combinations. In a double blind clinical trial (tinea) where cic was compared with a cic/hydrocortisone combination no statistical differences were found.

A fifty five-year old woman suffered from itching and scaling of the edge of her eyelid. She had long used topical corticosteroid for this condition. Direct examination of the scale by Parker KOH showed numerous fungal elements of spores and hyphae of Malassezia furfur. She was treated with oral itraconazole (100 mg daily or twice a week) for 8 weeks and was cured clinically and mycologically. The result suggests the possibility of treatment with an anti-fungal drug for seborrhoeic blepharitis or seborrhoeic dermatitis.

Seborrheic dermatitis is a chronic inflammatory disorder affecting areas of the head and trunk where sebaceous glands are most prominent. Lipophilic yeasts of the Malassezia genus, as well as genetic, environmental and general health factors, contribute to this disorder. Scalp seborrhea varies from mild dandruff to dense, diffuse, adherent scale. Facial and trunk seborrhea is characterized by powdery or greasy scale in skin folds and along hair margins. Treatment options include application of selenium sulfide, pyrithione zinc or ketoconazole-containing shampoos, topical ketoconazole cream or terbinafine solution, topical sodium sulfacetamide and topical corticosteroids.

Several studies indicate that Pityrosporum ovale plays an important role in seborrhoeic dermatitis. Many of these are treatment studies which describe the effectiveness of antimycotics, paralleled by a reduction in the number of P. ovale colonies and then recolonization, leading to a recurrence of seborrhoeic dermatitis. In this study 20 patients with seborrhoeic dermatitis of the scalp were treated with terbinafine (Lamisil) 1% solution once daily for 4 weeks. Eleven of 18 patients (61%) were cured and they were still free of lesions 2 weeks after stopping treatment. No side-effects related to treatment were seen. There was also a significant reduction in the number of P. ovale colonies. This may explain both the good clinical effect and the observation that all patients who were cleared of P. ovale were still free of lesions 2 weeks after stopping treatment.

Seborrheic dermatitis (SD) is a common dermatologic disorder with a characteristic facial distribution. It occurs most commonly on the scalp, nasolabial folds, external ear canal, and on the hair-bearing areas of the face. The reason that lesions occur in this particular distribution is not known. Theories concerning the etiology of this distribution involve increased sebum production and implications of Pityrosporon ovale as a causative agent. In the course of evaluating the results of analysis with a very sensitive thermal imager, we were struck by a marked regional variation in the temperature of facial skin. The warmer areas of the face were those commonly affected by seborrheic dermatitis. These findings suggest that skin temperature plays a role in the etiology of SD. The following study was conducted to formally examine and confirm this relationship.


Subjects and Methods
---------------------


We used an IR-M700 thermal imager (Mitsubishi Electronics America, Cypress, Calif) with ultrahigh resolving power (>410 000 pixels) to obtain thermal images of the faces of 25 normal individuals (age range, 22-84 years). None of the patients studied had SD or other dermatitis involving the face, scalp, or ears. The polarity of the imager was set so that warm areas appeared dark and areas of lower temperature appeared light. Although the absolute temperature of the images could not be determined, the high resolution of the imager clearly demonstrated the relative warmth or coolness of distinct areas on the face.


Results
-------

The temperature pattern of skin on the face was markedly heterogeneous (Figure 1). The temperature was a mosaic of warm and cold areas, with some variability from one patient to the next, as previously noted by others.1 However, certain areas of the face were consistently warmer than others, as indicated in Table 1. Consistently warm areas included the nasolabial fold, external ear canal, hair-bearing areas of the scalp, and the beard and mustache in subjects who had facial hair. By contrast, the cheek, nose, earlobes, and chin were consistently cooler. This occurred in all subjects, regardless of age and sex. There was a striking correlation between the warmer areas of the face and the distribution of lesions in SD, as described in standard texts.2, 3

Comment
-------


We have made the fortuitous observation that there is a striking correlation between areas of relative warmth on the face and the distribution of lesions in SD. Using an ultrasensitive thermal imaging device originally developed for military use, we found that there is a striking heterogeneity in the temperature pattern of facial skin. Some areas are substantially and consistently warmer than others. Areas of relative warmth include the nasolabial folds, external ear canal, hair-bearing areas of the scalp, and the beard and mustache in subjects with facial hair, while cool areas include the cheeks, nose, earlobe, and chin. The patterns of temperature difference were reproducible; hot and cold areas were similarly distributed in 25 different individuals. The areas of relative warmth were unrelated to pathological skin conditions, since none of these subjects had any evidence of facial or scalp dermatitis.

There was a striking correlation between the warm areas of the face and the distribution of lesions in SD. This extended to hair-bearing scalp, which becomes cool when hair is lost. Of interest is that SD clears in hair-bearing areas that become bald.4 The reason that high skin temperature seems to favor the appearance of SD lesions is unknown. Perhaps P ovale, the organism thought to be an etiologic agent in the pathogenesis of SD, grows best at higher temperatures. Also, areas of the skin that are predisposed to develop SD generally have a higher proportion of sebaceous glands, and it may be that these glands are associated with increased cutaneous blood flow and therefore higher skin temperatures.

An insulin quantification study in patients with seborrheic dermatitis is useful not only for providing further information about glucose metabolism in this disease, but also as an insight into a possible association and a role for hyperinsulinism in the pathogenesis and cause of seborrheic dermatitis.

There are few documented studies of glucose and its metabolism in persons with seborrheic dermatitis. Glucose tolerance has been reported to be increased in the blood and skin of patients with seborrheic dermatitis.1 This observation has been suggested to be a result of either a state of hyperinsulinism or a higher glucose turnover rate at the tissue level.1

Hyperinsulinism has also been associated with psoriasis and acanthosis nigricans, dermatologic disorders involving the hyperproliferation of epidermal cells.2, 3 While the hyperinsulinism in psoriasis appears to be a result of endogenous insulin resistance, there has been a discussion of the role of hyperinsulinism in the origin of acanthosis nigricans. In the case of seborrheic dermatitis, while earlier studies suggested a hyperproliferative mechanism for the disease, more recent studies support the etiological role of Malassezia .4

The purpose of this study was to determine whether patients with seborrheic dermatitis have a higher level of circulating insulin compared with the normal population, which could indicate the existence of hyperinsulinism and suggest a possible association and role for it in seborrheic dermatitis.

Subjects and Methods
----------------------

In selecting the patients with seborrheic dermatitis (excluding simple dandruff), the presence of pruritus was not a criterion. Infantile seborrheic dermatitis was excluded by using a minimum age cutoff level of 18 years. Patients with Parkinson disease were excluded to avoid any confounding factor due to the higher prevalence of seborrheic dermatitis in persons with parkinsonism.5 Since drug eruptions caused by chlorpromazine, cimetidine, and methyldopa may mimic seborrheic dermatitis,5 patients taking these medications were excluded. A history of treatment for seborrheic dermatitis was not a criterion. The control subjects, who were volunteers recruited through a posted advertisement, were determined not to have seborrheic dermatitis on the basis of a medical history taking and physical examination.

Consecutive volunteer sampling was used for both the patients and the controls. After ruling out diabetes mellitus by including only those individuals whose fasting blood glucose level was lower than 6.1 mmol/L (110 mg/dL), fasting blood samples from all 20 patients and 20 healthy controls were quantified for insulin using a serum iodine I 125 radioimmunoassay (Diagnostic Systems Laboratories Inc, Webster, Tex).

Results
-------

The results of the fasting blood glucose and serum insulin measurements, as well as other clinical parameters, for patients and controls are demonstrated in Table 1 and Table 2, respectively. Assuming a common SD of 7, and using a 2-group t test with a .05 2-sided significance level, a sample size of 20 in each group would have a power of 0.59, giving this study a type II error of about 0.41.


Comment
-------


In this study, the mean fasting serum insulin concentrations in patients with seborrheic dermatitis are not significantly different from that of the control group, indicating that an association between hyperinsulinism and this disease is unlikely. Therefore, the increased glucose tolerance previously reported in these patients cannot be caused by hyperinsulinism. In contrast, considering a physiological pancreatic response to glucose stimulation for the release of insulin, hyperinsulinism would be associated with insulin resistance and an impaired glucose tolerance,6 such as that seen in psoriasis.2

Increasing age and obesity (defined as >120% ideal body weight) have been associated with impaired glucose tolerance and hyperinsulinism, respectively.7 Our patients were slightly younger than the control subjects (302 vs 402 years; P =.004), which might result in a slightly lower age-related insulin concentration. The weights of the patients (expressed as percent ideal body weight) were not significantly higher (P=.08), even though 9 patients compared with 6 controls were 20% or more above their ideal weights. Nevertheless, significant differences in insulin concentrations between the 2 groups were not observed (P=.13). The hyperinsulinism observed in patient 12 is believed to be an isolated finding, and is most probably related to his state and degree of obesity (166% ideal body weight).

Finally, despite the suggestions of a role of hyperinsulinism in the origin of such hyperproliferative disorders as acanthosis nigricans, this study further disfavors the previously assumed hyperproliferative cause of seborrheic dermatitis with hyperinsulinism as a possible causal factor. Accumulating evidence indicates a stronger support for a mycological origin for this disease.

AB - This study examined the humoral immune responses to Malassezia furfur serovars A, B and C of 10 patients with pityriasis versicolor, 10 patients with seborrheic dermatitis and 20 age- and sex-matched controls. A transferable solid-phase ELISA was used to determine titres of total Igs, IgM, IgA and IgG specific to M. furfur serovars A, B and C. The results demonstrated that patients with seborrheic dermatitis had a significantly higher titre of total Igs to serovar A than patients with pityriasis versicolor; and that patients with seborrheic dermatitis had a significantly higher titre of IgA to serovar C than patients with pityriasis versicolor. The titres of total Igs for controls and patients with seborrheic dermatitis were significantly lower to serovar B than to serovar C. A modified TSP ELISA was used to determine the titres of the IgG subclasses. Titres of IgG1,3,4 to serovar B were significantly higher in seborrheic dermatitis patients than pityriasis versicolor patients and titres of IgG3 to serovar A were significantly higher in seborrheic dermatitis patients than pityriasis versicolor patients. However, despite the differences between the patient groups, none of these results was significantly different to those of controls. Thus, this study did not demonstrate any differences in humoral immunity of patients suffering from Malassezia-associated dermatoses when compared to normal controls. These results may suggest that the humoral immune response to M. furfur is not related to the pathogenesis of Malassezia-associated dermatoses, but simply to the carriage of M. furfur on the skin.

AB - Cutaneous fungal infections are a major source of morbidity in HIV-infected patients, and their management poses special challenges. Superficial mycoses, such as tinea pedis, tinea cruris, tinea corporis, and onychomycosis, are no more common in HIV-infected patients than in the HIV-negative population but are of greater severity. Although they respond to topical and systemic antifungal agents, HIV-positive patients are predisposed to frequent recurrences. Unusual types of fungal infections such as Majocchi's granuloma are more likely to develop in HIV-infected patients and respond best to systemic antifungal therapy with imidazoles or triazoles. Infections with Candida albicans develop in virtually all HIV-positive patients. Although mucosal involvement is the most common, patients may also develop superficial cutaneous infections. Topical agents are frequently all that is necessary, but in some, oral medications are required. Although fluconazole is effective, an appreciable number of isolates are resistant. Patients with pityriasis versicolor and seborrheic dermatitis, in which Pityrosporum species are thought to be involved, respond well to short courses of oral ketoconazole. Milder forms of seborrheic dermatitis can also be treated with low-potency topical steroids or topical ketoconazole. The oral triazole fluconazole is not particularly effective in the management of seborrheic dermatitis. Although the cause of eosinophilic pustular folliculitis, a common disorder in immunosuppressed HIV-positive patients, is unknown, some can be cured with high doses of itraconazole, suggesting that fungi are important in the pathogenesis of the disease in some patients.

It is both a saprophyte and an opportunistic pathogen associated with pityriasis versicolor, Pityrosporum folliculitis, seborrheic dermatitis, and some forms of atopic dermatitis. Systemic infections have also been described. In this article the diagnosis and management of pityriasis versicolor, Pityrosporum folliculitis, seborrheic dermatitis, and atopic dermatitis will be discussed.

AB - It has been postulated that patients with Malassezia furfur-associated dermatoses have a deficient cell-mediated immune response to M. furfur. This study examined the cell-mediated immune responses to M. furfur serovars A, B and C of 10 patients with pityriasis versicolor and 10 age- and sex-matched controls; and 10 patients with seborrheic dermatitis and 10 age- and sex-matched controls. The responses to each serovar of M. furfur were assessed using the lymphocyte transformation assay and the leukocyte migration inhibition assay. The lymphocyte transformation responses of the patients with pityriasis versicolor to M. furfur serovars A, B and C (0/10, 6/10 and 5/10 respectively) were not significantly different from those of controls (0/10, 2/10 and 1/10). However, for patients with seborrheic dermatitis, significantly more patients' lymphocytes responded to serovars B and C (6/10 and 6/10 respectively) than those of controls (1/10 and 1/10). No patient or control responded to serovar A. In the leukocyte migration inhibition assay, the leukocytes from a greater proportion of patients with pityriasis versicolor (5/7) responded to serovar B than controls (2/10); and the leukocytes from a greater proportion of patients with seborrheic dermatitis (4/10) responded to serovar C than controls (0/9). Thus, this data did not indicate the presence of any cell-mediated immune deficiency to M. furfur in patients with pityriasis versicolor or seborrheic dermatitis, as measured by the lymphocyte transformation assay or the leukocyte migration inhibition assay. The greater responsiveness of T lymphocytes from patients may indicate that T lymphocytes might be involved in the pathogenesis of these diseases.

AB - Cutaneous involvement with disseminated histoplasmosis occasionally occurs in patients infected with the human immunodeficiency virus. We describe a profoundly immunocompromised patient with acquired immunodeficiency syndrome who had concomitant psoriasis, seborrheic dermatitis, and disseminated histoplasmosis, each with similar features. Findings of a skin biopsy specimen from a lesion on the forehead showed an infiltrate of histiocytes filled with Histoplasma capsulatum. In disseminated histoplasmosis involving the skin, lesions may have features more characteristic of a papulosquamous dermatosis than an infectious disease. In patients infected with human immunodeficiency virus, especially those with low numbers of CD4+ cells, serious infectious diseases may have unusual features and may assume the appearance of concomitant inflammatory diseases.

AB - BACKGROUND: In infantile seborrheic dermatitis (ISD) several different pathogenetic mechanisms have been proposed. OBJECTIVE: The purpose of the study was to investigate the importance of essential fatty acids (EFAs) and their metabolites in the origin of ISD. METHODS: The serum EFA patterns of 30 children with ISD, 1 to 6 months of age, were studied for 2 to 5 months. Blood samples were obtained at the time of diagnosis and after spontaneous recovery. Control samples were taken from age-matched healthy children. RESULTS: In children with active dermatitis levels of EFA 18:1w9 were increased and levels of 18:2w6 were decreased, whereas 20:4w6 levels remained normal. The rare fatty acid 20:2w6 was found in significant amounts in 20 patients, but at only barely detectable levels in the controls. All deviant values but the levels of 20:2w6 were normal at the time of recovery. Breast milk samples were obtained at the time of diagnosis from the patients' mothers and from a control group consisting of healthy nursing mothers. The EFA patterns were identical. The differences in EFA pattern between children with ISD and those free of skin disease were significant. The normalization of the deviation in ISD paralleled the recovery at any age it occurred. CONCLUSION: The laboratory findings suggest a transient impaired function of the enzyme delta-6-desaturase. The altered EFA pattern in ISD may be important in the pathogenesis of the disease.

AB - Forty-four patients with seborrhea and seborrheic dermatitis of the scalp were treated with either bifonazole shampoo (22 patients) or the vehicle shampoo (22 patients) in a randomized, double-blind vehicle-controlled study. The patients were instructed to wash their scalps 3 times weekly for 6 weeks and were examined every 3 weeks. Responses were evaluated by clinicians using a clinical grading of scaling, erythema and overall improvement, and also by the patients, who assessed pruritus and overall improvement, using a scale of 0 to 3. The improvement following the bifonazole shampoo was found to be significantly greater than that achieved with the vehicle shampoo in regard to the clinical evaluation of scaling (p = 0.01) as well as patient evaluation of pruritus (p = 0.008) and overall improvement (p = 0.03). No major adverse side effects were recorded.

AB - BACKGROUND: Previous studies have suggested that Pityrosporum yeasts may be important in the pathogenesis of seborrheic dermatitis (SD). SD occurs more frequently and has a different clinical appearance in patients who are human immunodeficiency virus (HIV)-seropositive than in HIV-seronegative patients. OBJECTIVE: Our purpose was to investigate the role of Pityrosporum yeasts in the pathogenesis of seborrheic dermatitis in HIV-seropositive patients. METHODS: Twenty-eight HIV-seropositive patients, including seven patients with SD and 21 without SD, and 20 HIV-seronegative patients with SD (n = 10) and without SD (n = 10) were investigated. Quantitative Pityrosporum cultures were taken from the face, chest, and back. RESULTS: None or only a small amount of Pityrosporum yeasts were cultured from SD lesions and SD predilection sites in HIV-seropositive patients. From the SD lesions in the HIV-seronegative control group large amounts of Pityrosporum yeasts were cultured. CONCLUSION: The results of this and other studies suggest that Pityrosporum yeasts play no role in SD in HIV-seropositive patients and that SD in these patients is a distinct entity to be separated from "classical" SD in HIV-seronegative patients.

PT - CLINICAL TRIAL; JOURNAL ARTICLE; MULTICENTER STUDY; RANDOMIZED CONTROLLED TRIAL
AB - BACKGROUND: Seborrheic dermatitis, an inflammatory dermatosis that principally affects sebaceous areas, may be related to the presence of the yeast Pityrosporum ovale. Topical therapy with corticosteroids, although in general effective, may be associated with several unwanted effects. The development of alternative non-steroid-based therapies may enable patients to avoid the use of topical steroids and help elucidate the pathogenesis of the disease. OBJECTIVE: This study aimed to assess the efficacy and safety of an ointment containing 8% lithium succinate in the treatment of seborrheic dermatitis. METHODS: The study consisted of a multicenter placebo-controlled clinical trial in 227 adult patients. RESULTS: Lithium succinate ointment was significantly more effective than placebo in treating all the symptoms of seborrheic dermatitis. No specific unwanted effects were associated with its use. Relapse was slow when treatment was stopped. CONCLUSION: The effectiveness of lithium succinate ointment in the treatment of seborrheic dermatitis adds to the evidence implicating P. ovale in the pathogenesis of that condition.

AB - Cutaneous eruptions are commonly seen in acquired immunodeficiency syndrome (AIDS). Seborrheic dermatitis in this patient population is usually more severe and difficult to diagnose and treat. The butterfly distribution of the rash and the interpretation of the biopsy may suggest a diagnosis of discoid lupus erythematosus, unless the pathologist is aware of the underlying immunodeficiency. We present two cases of patients with documented acquired immunodeficiency syndrome whose initial biopsies were interpreted as discoid lupus but whose cutaneous seborrheic dermatitis actually paralleled human immunodeficiency virus disease activity.

No differences are found between HIV sero-positive and sero-negative individuals with SD. The deficiency of PUFA-PL (mainly C20: 3 n-6, C20: 4 n-6 and C22: 6 n-3) which is accompanied by a significant increase of saturated palmitic and stearic acids (P less than 0.001), does not appear to be associated with an active lipoperoxidative process in the plasma. The significant blood deficiency of Vit E, GSH-Px, and particularly of PUFA-PL, may play a pathogenetic role in seborrheic dermatitis.

AB - Skin surface lipids of patients affected with seborrheic dermatitis both HIV sero-negative (C group) and HIV sero-positive (B group) have been studied by capillary Gas chromatography-Mass spectrometry (GC-MS) in comparison with normal age matched controls (A group) to determine whether, among the three groups of individuals, there were qualitative and quantitative changes in lipid class composition and in the fatty acid and alcohol components of lipid fractions. With regard to percent composition of skin surface lipid fractions, no significant differences were found between HIV sero-positive and HIV sero-negative patients with seborrheic dermatitis. The observed significant reduction of total lipids (micrograms/sq cm) in the sites affected with the disease in comparison with controls was associated with a slight but significant decrease of squalene (P less than 0.05) and with a corresponding increase of cholesterol and cholesterol esters (P less than 0.05). These abnormalities in lipid fractions and total lipids were not observed in the uninvolved skin of subjects with seborrheic dermatitis. Fatty acid and alcohol patterns of skin lipid fractions were not significantly different among the three groups of individuals.

AB - Seborrheic dermatitis (SD) is frequent in adults. Its aetiology is unknown, and the alleged causative effect of Pityrosporum-type yeasts is strongly controverted. Nutritional, genetic and neuropsychological factors may play a part in its occurrence. The responsibility of immunological factors has recently been illustrated by the high prevalence of SD in patients with acquired immunodeficiency syndrome. We found a high frequency of SD in patients under treatment for carcinomas of the upper respiratory and digestive tracts (URDT), and in order to confirm this finding we carried out a prospective case-control epidemiological study. Since most patients with URDT carcinoma are heavy drinkers and smokers, we divided our controls into two groups: chronic alcoholics without cancer (Group B) and patients with non-URDT cancers. At the time of admission, all patients were examined by the same physician, and SD was diagnosed on clinical grounds. Cases (Group A) comprised 50 patients (48 men, 2 women; mean age 56 years) with URDT carcinoma. All were alcohol and tobacco addicts. Thirty-six of these patients had undergone surgery for their cancer, and among these 19 had received radiotherapy, 8 chemotherapy and 18 both chemo- and radiotherapy. The first control group (Group B) also comprised 50 patients, all male, with a mean age of 59 years, who had been admitted for diseases due to alcoholism but showed no evidence of cancer. The second control group (Group C) consisted of 50 male patients (mean age 69 years) whose cancer was not an URDT carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS).

AB - This paper discusses the relation between the lipophilic dimorphic yeast Pityrosporum ovale and seborrheic dermatitis. A review of studies concerning the microbiology in seborrheic dermatitis and immune reactions to P ovale are given. In our own studies with quantitative cultures, no significant difference was found in the number of P ovale in patients compared with controls, or between healthy and lesional skin in the patient group. IgG serum antibodies against P ovale cells estimated with indirect immunofluorescence did not show any difference between patients and controls, but a significant difference was found when a P ovale protein extract and ELISA were used. Immunological investigation on serum samples were done on 30 patients with seborrheic dermatitis. Defects were found in their T-cell function. The number of P ovale is of importance in those individuals who are susceptible to seborrheic dermatitis and the development of the disease depends on the way their immune system reacts to the antigens derived from P ovale.

AB - One hundred patients with facial seborrheic dermatitis and 42 control subjects were studied. The number of periodic acid-Schiff-positive Pityosporum ovale yeast cells in skin scrapings per high-power field were counted and designated 1 + to 4 +. Our data indicate a correlation between the density of P. ovale and the clinical severity of seborrheic dermatitis, both before and after therapy with a precipitated sulfur/salicyclic acid shampoo. The data support the concept that yeast contributes to the pathogenesis of seborrheic dermatitis.

AB - Pityrosporum ovale is a lipophilic yeast commonly present in the seborrheic areas of the skin of adults. Fifty-five young adult patients with atopic dermatitis, 19 patients with seborrheic dermatitis, and 19 healthy control subjects were examined for immune reactions to P. ovale, including tests for specific IgE antibodies (prick test, histamine release), IgG antibodies and epicutaneous testing. IgE antibodies against P. ovale were found in two thirds of the patients with atopic dermatitis and were more frequent in patients with lesions predominantly in the seborrheic areas. In addition, some atopic patients had positive reactions to epicutaneous tests, which suggest that delayed allergic reactions to P. ovale may also be important. In patients with seborrheic dermatitis, no evidence of immediate or delayed hypersensitivity to P. ovale was found. IgG antibody levels were low in all groups.

AB - The high prevalence of seborrheic dermatitis in HIV-infected subjects has led to intensified the discussion of the etiopathogenesis of this dermatological disease. There is increasing controversy about the significance of Pityrosporum in seborrheic dermatitis. On the other hand, recent clinical and experimental data favor the role of intestinal candidiasis in seborrheic dermatitis: a high quantity of Candida in the feces of the affected patients, elevated phospholipase activity of the Candida sp. with special pathogenic relevance for mucosal adhesion and fast and long-lasting regression of seborrheic dermatitis after vigorous therapy with oral nystatin. Similar findings have been recorded in the seborrheic forms of psoriasis.

AB - The possible causative role of the yeastlike fungus Pityrosporum (Malassezia) orbiculare in the pathogenesis of seborrheic dermatitis in patients with and without acquired immunodeficiency syndrome (AIDS) has been discussed but not resolved. Ten patients with AIDS-related seborrheic dermatitis were studied for the presence of Pityrosporum organisms. On the basis of a quantitative correlation between numbers of yeast cells adherent to and extruded from keratinocytes and the clinical severity of seborrheic dermatitis, an association, if not a causative role, for Pityrosporum is strongly suggested in seborrheic dermatitis in patients with AIDS. This association was further strengthened by the marked clinical response to ketoconazole in two patients with a concomitant decrease in the number of Pityrosporum cells per keratinocyte.

AB - The presence of Pityrosporum ovale was investigated in four groups of infants age 1 to 24 months, 15 with infantile seborrheic dermatitis, 15 with infantile atopic dermatitis, 15 with other infantile dermatoses, and 15 healthy infants. Samples were taken from the scalp, face, presternal area, and inguinal area. Pityrosporum ovale was detected by smears and/or cultures in 73% of infants with seborrheic dermatitis, 33% with atopic dermatitis, 33% with other dermatoses, and 53% of healthy infants. The percentages of positive smears and/or cultures from four body sites in each patient group were 42% for seborrheic dermatitis, 20% for atopic dermatitis, 20% for other infantile dermatoses, and 23% for healthy infants. The majority of infants with positive cultures or positive direct examination for P. ovale were between 1 and 8 months of age. The organism was isolated in 28% of samples taken from the scalp, 32% from the face, 30% from the presternal area, and 15% from the inguinal area. Patients with infantile seborrheic dermatitis were treated with 2% topical ketoconazole cream for two weeks. Eleven of these children were clinically cleared and 13 became mycologically negative. Pityrosporum ovale was significantly more frequent in infants with seborrheic dermatitis than in those with atopic dermatitis, in other infantile dermatoses, or in healthy infants, both in the total number of infants with positive smears and/or cultures and in the number of positive samples per body area (P less than 0.05).

AB - Based on clinical features, infantile seborrheic dermatitis (ISD) can be classified as follows: true seborrheic dermatitis (SD), psoriasiform seborrheic dermatitis (Psor SD), and erythrodermic seborrheic dermatitis. We reviewed the records of 72 children who had been affected by ISD several years earlier to investigate the evolution of disease, to evaluate the patients for the presence of new skin lesions, and to study family histories with respect to these conditions. In addition, we attempted to determine if there is any connection among the initial features of ISD and the types of skin lesions, and atopy or psoriasis. On reexamination, our patients previously diagnosed as having SD showed a larger variety of new skin lesions than those who had Psor SD, and 15% had developed atopic dermatitis. Atopic dermatitis was not present at follow-up in the children with previously diagnosed Psor SD. Psoriatic lesions were present in similar percentages in both groups at the time of reevaluation. Investigation of family history was not useful in predicting later development of psoriasis or atopic dermatitis. We conclude that the initial clinical features of ISD may be of prognostic value, and that SD and Psor SD are probably two different clinical entities.

AB - Seventy-two patients with seborrheic dermatitis were treated once daily with 2% ketoconazole cream (n = 36) or 1% hydrocortisone cream (n = 36) on a double-blind basis for 4 weeks. For the global evaluation, no significant difference could be seen between the two groups. The clinical response was 80.5% in the ketoconazole group and 94.4% in the hydrocortisone group. For the different symptoms combined (scaling, redness, itching, and papules), no significant difference was seen between the two groups when the total scores at week 2 and at week 4 were compared with the initial scores. The incidence of side effects in both groups was comparably low.

AB - To confirm T-cell changes previously reported in atopic eczema, to compare T-cell subset values in atopic and seborrheic infants, and to determine whether T-cell subset assay would be a useful differentiating marker between atopic and seborrheic infants, three age- and sex-matched groups of normal, seborrheic, and atopic infants were recruited. T-cell subset values, total serum IgE, and serum IgE to specific allergens (Dermatophagoides pteronyssimus, cat epithelium, dog dander, rye grass, egg white, and milk) were measured. The results showed that total and allergen-specific IgE levels were higher in atopic disease in infancy, but no statistical differences in T-cell subset values between seborrheic and atopic infants were found. T-cell subset values are therefore not a reliable differentiating marker between atopic and seborrheic eczema in infancy.

Two patients did not return for follow-up. Sixteen of eighteen (89 percent) in the group treated with propylene glycol showed healing, compared to six of nineteen (32 percent) in the other group. In twenty patients quantitative cultures for Pityrosporum orbiculare were taken. The number of organisms was reduced significantly after treatment with the propylene-glycol-containing solution but not in the other group. This propylene-glycol-containing solution was easy to apply, cosmetically attractive, and may be an alternative to corticosteroids for the treatment of seborrheic dermatitis of the scalp.

Although significant differences were detected in both bacterial and yeast counts between different sites on the body, no significant qualitative or quantitative differences were found between the three groups of subjects. Whereas abnormalities of the skin flora have been described in seriously ill patients and in individuals subjected to occlusion, we were unable to demonstrate any changes in skin flora in patients with malignant disease and seborrheic dermatitis. Our results do not support the view that increased numbers of Pityrosporum yeasts are important in the pathogenesis of seborrheic dermatitis.

The subjects were studied for numbers of Malassezia ovalis (Pityrosporum ovale) cells in their scalp scale; changes in numbers of yeast cells and morphology of M. ovalis were tabulated along with clinical assessment of improvement. The 2% ketoconazole cream, but not the placebo cream, reduced the numbers of viable yeast cells on the scalp. The clinical effect of 2% ketoconazole cream was good (75%-95% improvement) or better in eighteen of twenty subjects; the placebo cream produced good results in only three of seventeen subjects treated. Results of this study are consistent with the view that M. ovalis plays a central role in the pathogenesis of seborrheic dermatitis.

AB - Pityrosporum ovale appears to play an important role in the pathogenesis of seborrhoeic dermatitis. Ketoconazole is an antimycotic agent with a high in vitro and in vivo efficacy against P. ovale. We performed a multicentre study to investigate the efficacy of ketoconazole 2% shampoo in the treatment and prophylaxis of seborrhoeic dermatitis and dandruff. Five hundred and seventy-five patients presenting with moderate to severe seborrhoeic dermatitis and dandruff of the scalp were treated with 2% ketoconazole shampoo twice weekly for 2-4 weeks, producing an excellent response in 88%. Of those patients who responded, 312 were included in a prophylactic phase, lasting 6 months. These patients were treated with the active preparation (shampoo containing 2% ketoconazole) once-weekly, once every other week, alternating with placebo (shampoo without ketoconazole), or with placebo only once-weekly. Forty-eight (47%) patients in the placebo group experienced a relapse of seborrhoeic dermatitis, compared with 23 (19%) patients in the active treatment group, and 31 (31%) patients in the active/placebo group. The medication was well tolerated in all three groups. We conclude that ketoconazole 2% shampoo is highly effective, not only in clearing scalp seborrhoeic dermatitis and dandruff, but also in preventing relapse of the disease when used prophylactically once weekly.

The adherence assay was performed with one strain of M. furfur and stratum corneum cells from 30 healthy individuals and from 28 patients with seborrhoeic dermatitis. Stratum corneum cells from patients with seborrhoeic dermatitis contained significantly lower numbers of adherent M. furfur cells than cells from healthy individuals. No correlation was found with sex or age. The adherence assay was also performed with stratum corneum cells from one healthy individual and M. furfur strains from 15 patients with seborrhoeic dermatitis and 13 healthy controls. Malassezia furfur strains from patients with seborrhoeic dermatitis showed the same in vitro capacity for adherence to stratum corneum cells as strains from healthy individuals. This in vitro study does not indicate that M. furfur adherence to human stratum corneum cells is of importance in the pathogenesis of seborrhoeic dermatitis.

The results revealed that, in male patients, 46/49 cases were positive for Malassezia furfur on the face and 30/48 cases were positive for M. furfur on the scalp. In female patients, 7/13 cases were positive for M. furfur on the face, and 6/17 cases were positive for M. furfur on the scalp. Anti-mycotic agents were excellent in 50% and good in 31% of the spore-positive cases, yielding an overall efficacy rate of 81%. In contrast, the treatment of the face with vehicle alone showed only one excellent result out of 8 cases. Although clinical improvement was rapid on the side treated with a topical corticosteroid in the half-side-test, numerous fungal elements remained. While the improvement with anti-mycotic agents was slower than that with the corticosteroid, clinical improvement became evident by the third week of administration and fungal elements disappeared.

AB - The composition of the total skin surface lipid, free fatty acids and fatty acid of triglyceride was used in discriminant analyses to classify patients with severe acne vulgaris (AV), pityriasis versicolor (PV), seborrhoeic dermatitis (SD) and atopic dermatitis (AD). It was not possible to discriminate between the PV and SD patients but all the lipid groups gave a satisfactory separation between AV, PV + SD and AD patients. A similar separation was obtained when the sex of the patient was studied but not when both sex and disease were taken into account. The results suggest that there are fundamental differences in the composition of skin lipid between patients with microbially associated diseases, but the precise role of the organisms has not been ascertained.

All the patients were treated daily with topically applied borage oil (containing 24% gamma-linolenic acid). With this regimen they were completely free from all skin symptoms within 3-4 weeks. Analyses of essential fatty acids in serum showed aberrations as previously described, with elevated levels of 18:1w9 and 20:2w6. TEWL and water content were recorded at the time of diagnosis and after treatment from the right forearm in skin that was free from symptoms and not treated with borage oil. Twenty-five healthy children in an age-matched group without skin disorders were used as controls. Significant differences in TEWL between patients and controls were found before treatment. After treatment no significant differences were found. There were no significant differences between controls and patients regarding water content in the stratum corneum. Gamma-linolenic acid is suggested to be of importance in maintaining normal TEWL and also in promoting recovery in patients suffering from ISD.

AB - Recent studies suggest that epidermal skin lipids play an important role in the pathogenesis of skin diseases associated with seborrhoea or sebostasis. Depending on the state of the skin, various lipids are found in varying quantities and proportions. In some sebostatic diseases, in particular, altered enzyme activities relevant to the synthesis of lipids have been identified, which may account for alterations in epidermal lipid fractions. This concept represents a substantial modification of earlier ones, according to which sebostatic or seborrhoeic skin diseases were attributed solely to decreased or increased sebum lipids, respectively. This provides an important rationale for a new approach to the therapy of certain skin diseases with specific lipid fractions, such as ceramides.

Responses to six concentrations of sodium lauryl sulphate (SLS), applied to forearm skin, were assessed clinically and measured by laser Doppler flowmetry. Analysis of dose-response curves showed statistically significant increased susceptibility to SLS-induced irritation in patients with seborrhoeic dermatitis and atopic eczema compared with normal subjects. Increased susceptibility to chemical irritation may be important in the pathogenesis of seborrhoeic dermatitis.

AB - Twenty-one patients with seborrhoeic dermatitis were included in an open trial of lithium succinate ointment (LSO) for a total duration of 8 weeks. The same clinician made assessments of the severity of redness, scaling, greasiness and overall clinical impression of the condition every 2 weeks. Because the results appeared to be satisfactory, we decided to perform a double-blind, placebo-controlled trial of LSO. Thirty patients with seborrhoeic dermatitis were included. The results also demonstrated the beneficial effect of LSO. A significantly higher number of patients treated with LSO showed remission or marked improvement compared with placebo. The main adverse events demonstrated consisted of minor transient skin irritation and/or stinging sensation. Studying the in vivo inhibitory effect of LSO on the growth of Pityrosporum revealed that Pityrosporum did not significantly have its growth inhibited by lithium. Topical lithium succinate appears to be a safe and an effective treatment for seborrhoeic dermatitis. The product presumably acts as an anti-inflammatory agent.

Phagocytosis was complement dependent and reached a maximum after 40 min. Ketoconazole at 25, 50 and 100 mg l-1 had no significant effect on phagocytosis of P. ovale. However, when yeast cells were pretreated with ketoconazole for 2 h before exposure to the phagocyte monolayer there was a significant enhancement of phagocytosis with increasing drug concentration. Intracellular killing of P. ovale was assessed by methylene blue dye exclusion. In the absence of ketoconazole, 5% of intracellular yeast cells were killed following internalization for 2 h. Pretreatment of yeast cells with ketoconazole at 10 and 100 mg l-1 for 2 h prior to ingestion significantly increased intracellular killing to a maximum of 23%. This study demonstrates that yeast cells of P. ovale are readily ingested by human neutrophils by a complement dependent process. Phagocytosis is enhanced if the organism is exposed to ketoconazole before opsonisation and ingestion. The inability of neutrophils to kill P. ovale is modulated in the presence of therapeutic concentrations of ketoconazole.

AB - Numerous AIDS patients show the typical seborrheic eczema in a very prominent way. For this is an inflammatory disease, combination preparations were taken frequently which contain antimycotics and corticosteroids. We investigated 7 antimycotic compounds in 3 inflammatory models: amorolfin, ciclopiroxolamine (cic), fluconazole, ketoconazole, miconazole, naftifine, and rilopirox. In an in vitro model the inflammatory activity towards the 5-lipoxygenase was investigated. 1,000 mumol naftifine, 100 mumol ketoconazole, 50 mumol cic, and 10 mumol rilopirox inhibited 5-HETE by 90%. In a cell culture model only cic had a significant activity towards cyclo-oxygenase. In this model the inhibition of the prostaglandin E2 liberation by 1 mumol cic was 40%. In an in vivo model the anti-inflammatory activity on a mouse ear was investigated (arachidonic acid induced). In this model only cic showed a significant inhibition of inflammation (50%) at 1 mg/ear. These investigations show, that cic has a strong antiphlogistic activity. In an open clinical trial with 20 patients suffering from seborrheic eczema after 4 weeks on cic cream a strong inhibition of infiltration and flakiness had been observed. The antimycotic compound cic offers a possibility to treat inflammatory mycoses without using corticosteroid combinations. In a double blind clinical trial (tinea) where cic was compared with a cic/hydrocortisone combination no statistical differences were found.

PT - JOURNAL ARTICLE
AB - The yeast Pityrosporum orbiculare is thought to cause the folliculitis associated with seborrheic eczema. However, a combination of mechanical and microbiological factors may be involved, with follicular occlusion leading to yeast overgrowth and folliculitis. Scanning electron microscopy was used to investigate this hypothesis. Skin biopsy specimens obtained from patients with Pityrosporum folliculitis were examined by scanning electron microscopy before and after oral ketoconazole therapy. Patients with active disease showed occlusion of noninflamed follicles, which resolved after ketoconazole treatment. Follicular occlusion was not present in biopsy specimens obtained from unaffected controls nor was it related to the presence of P orbiculare. These findings suggest that follicular occlusion may be a primary event in the development of this folliculitis, with yeast overgrowth a secondary occurrence. The beneficial effect of ketoconazole in this disease may be due to direct effects on the follicle.

AB - In 65 patients with scalp psoriasis or seborrhoic dermatitis of the scalp, stool specimens, tongue swabs and scalp scales were examined for yeasts. The stool specimens showed in 70.8% of the patient group massive and in 7.7% moderate yeast colonization. Yeasts were found in 47.7% of the tongue cultures and in 12.5% of the scalp scales. Candida albicans was the predominant pathogen in the faeces and on the tongue. In comparison with a control group, frequency of yeasts in faeces and on the tongue in patients with psoriasis capillitii and seborrhoic dermatitis of the scalp could be shown to be significantly higher.

PT - JOURNAL ARTICLE
AB - The clinical differential diagnosis between seborrheic dermatitis and psoriasis vulgaris of the scalp can be difficult. We, therefore, tried to elaborate histopathological criteria for a differentiation of the two dermatoses. Forty excisional biopsies were analysed without knowing the clinical diagnosis. The histopathological substrate within the epidermis is characterized in psoriasis by dermatitis-like and in seborrheic dermatitis by psoriasis-like alterations. Therefore, in some cases a definite histopathological diagnosis could not be made. Strong criteria favouring psoriasis are: moderate condensed hyperkeratosis with alternating parakeratosis, PAS-reactive serum inclusions and Munro abscesses within the horny layer, spongiform pustles and neutrophilic leukocytes within the epidermis. Strong criteria for seborrheic dermatitis are: irregular acanthosis with relatively thin condensed orthoor parakeratotic horny layer, spongiosis and spongiotic vesicles, exocytosis of lymphocytes and the lack of any hard criterias for psoriasis. The results may suggest that seborrheic dermatitis of the scalp may transform into psoriasis in patients with a genetical disposition ("psoriatic diathesis", "latent psoriasis") via a Kobner reaction. The existence of the seborrheic dermatitis (Morbus Unna) is not doubted by these investigations.

AB - The composition of the scalp microflora was assessed quantitatively in normal individuals and in patients with dandruff and seborrheic dermatitis, disorders characterized by increasing scaling. Three organisms were constantly found: (1) Pityrosporum, (2) aerobic cocci, and (3) Corynebacterium acnes. Pityrosporum (mainly Pityrosporum ovale) made up 46% of the total microflora in normals, 74% in dandruff, and 83% in seborvheic dermatitis. The geometric mean number of organisms per cm-2 in non-dandruff subjects was 5.04 times 10-5; 9.22 times 10-5 in dandruff subjects; and 6.45 times 10-5 in those with seborrheic dermatitis. The cocci were dominantly Baird-Parker type SII and no quantitative or qualitative change occurred in the scaling disorders. C. acnes comprised 26% of the flora on the normal scalp, 6% in dandruff, and only 1% in seborrheic dermatitis. These results differ significantly from previous reports which describe a much more complex microflora and suggest an etiologic role for microorganisms in dandruff.

AB - Sodium sulfacetamide, penetrating antibacterial, in combination with hydrocortisone and sulfur, has enjoyed twenty years of remarkable safety, with outstanding efficacy and patient acceptance, in the prescription treatment of pustular acne and severe, refractory seborrheic dermatitis. Recently, this combination has been reported to be highly effective concomitant therapy for perioral dermatitis. Almost paradoxically, it achieves these desired goals without the excessive erythema and discomforting irritation associated with retinoic acid and benzoyl peroxide.

AB - Twenty-five infants with generalized seborrhoeic dermatitis have been studied with reference to the provision of optimum treatment. Leucocyte counts and chest x-ray examination are recommended in every case. Irrespective of clinical findings, antibiotics should be given to patients with overt bacterial infection and those with leucocytosis, shift to the left, and toxic granulation. One group of infants was treated with vitamin B complex plus biotin given slowly intravenously over 24 hours; a second group was given only biotin intravenously over 2-3 hours; and a third group only biotin over 1-2 minutes. A fourth group was treated with both biotin and antibiotics for confirmed or suspected superimposed bacterial infection. The results were excellent in all groups. Skin lesions improved within 4-8 days and cleared completely within 15-30 days. Intravenous administration of biotin is recommended as less painful and less dangerous than multiple intramuscular injections.

AU - Gloor M
PT - JOURNAL ARTICLE
AB - The treatment of seborrhoea oleosa capillitii should aim at inhibiting depletion of the sebaceous glands, lipid synthesis in the sebaceous gland and microbial lipolysis of the triglycerides in the scalp and hair lipids. The use of isopropyl alcohol as a vehicle in a hair tonic reduces sebum depletion. Coal tar and estrogens reduce the lipid synthesis in the sebaceous gland. The lipolysis can be inhibited by various surfactants, isopropyl alcohol, colloidal sulphur, selenium disulphide, Omadine MDS and benzoyl peroxide. In the treatment of pityriasis simplex capillitii (dandruff) one aims at achieving inhibition of mitosis in the epidermis and, if possible, an additional "keratolytic" effect. Inhibition of mitosis could be demonstrated for coal tar, corticosteroids, selenium disulphide, cadmium sulphide, Omadine MDS, Zn Omadine and ichthyol sodium. Colloidal sulphur, salicylic acid, Omadine MDS and various surfactants act "keratolytically"

AB - In patients with tinea versicolor, Pityrosporum orbiculare was cultured from tinea versicolor lesions in 100%, from normal-looking skin in 80%, and from apparently healed lesions in 69%. P. orbiculare was isolated from normal skin in 85% of patients with seborrheic dermatitis and in 90% of volunteers. The best substrate for isolation of P. orbiculare was a peptone-glucose-yeast extract medium containing glycerol monostearate and Tween 80, overlaid with olive oil. Germ tubes were produced when P. orbiculare was incubated in an atmosphere containing air with 7% CO2. Cultures of P. orbiculare and P. ovale did not show any fluorescence in Wood's light. The in vitro activity of miconazole, clotrimazole, econazole, sodium omadine, and sodium thiosulphate against P. orbiculare was found to correlate to the good clinical effect of these drugs in tinea versicolor. In addition several substances used as solvents or in vehicles had an inhibitory activity against P. orbiculare in vitro. Inoculation with P. orbiculare under plastic occlusion on the glabrous follicle-rich inside of the rabbit ear resulted in a tinea versicolor-like lesion after I week in 3 of 4 animals. One week after inoculation with P. orbiculare under plastic occlusion, experimental infections similar to those found clinically in tinea versicolor were seen in 10 of 12 patients with a history of tinea versicolor and in 3 of 6 normal volunteers. It was not possible to produce experimental infections without occlusion. Spontaneous healing usually occurred. In a retrospective study of 232 patients and prospective survey of 48 patients regarding susceptibility factors in tinea versicolor a higher (10.4%) than expected (3.8%) connection to seborrheic dermatitis was found.

AB - Among 466 children under the age of 12 years who presented with eczema in a 5-year period, 68 p. 100 were atopic. 136 had various atypical signs of atopy. 44 suffered from pityriasis alba of sufficient intensity to justify referral for this reason; 10 had the typical features of seborrhoeic dermatitis of infants. 27 suffered from "forefoot" eczema ("juvenile plantar dermatosis"). The course and characteristics of this condition are discussed and compared with the series recently described in the West of Scotland. Our cases were exactly similar except for an aggravation in the summer months and the fact that our cases responded poorly to topical corticosteroids alone though improved with coal tar. Atopy and contact sensitivity to shoe materials are rare in both groups. We feel that this may be classified as "frictional" dermatitis and agree with our Scottish colleagues that the introduction of nylon socks during the last ten years may be important.

AB - Those caring for children should recognize that cutaneous findings are common in children with host defense defects. Atopic dermatitis, recurrent or persistent pyodermas, candidiasis and lupus-like syndromes, should signal the possibility of host defense deficiencies. Particularly the findings of atopic dermatitis and recurrent skin abscesses should alert the clinician to determine serum IgE levels and neutrophil chemotaxis in such patients. The triad of generalized seborrheic dermatitis, failure to thrive, and diarrhea in an infant should bring to mind Leiner disease or severe combined immunodeficiency disease.

AB - The role of microorganisms in dandruff was studied, by suppressing individually and then collectively the three major components of the scalp microflora. The effect on dandruff was assessed subjectively by clinical grading and objectively by the corneocyte count. No effect on dandruff was demonstrated when scalp organisms were suppressed. In the second group of experiments, dandruff was suppressed by selenium sulfide shampooling and the effect of continued suppression of Pityrosporum with topically applied amphotericin was measured. According to our criteria, dandruff returned to pretreatment levels, despite continued suppression of Pityrosporum. The studies demonstrate that the increased number of scalp microorganisms found in dandruff occurs as a secondary event to increased nutrients and that scalp organisms play no primary role in the pathogenesis of dandruff.

AB - One hundred and twenty-three children who had napkin dermatitis, with or without a secondary sensitization eruption, in infancy were reviewed 5-13 years later. Of the seventy-one who had a predominantly psoriasiform secondary eruption, twelve (17%) had psoriasis at review-three (4%) had atopic eczema. None of the forty treated for a predominantly seborrhoeic secondary eruption had psoriasis at review-15 (37%) had atopic eczema. The psoriasiform group had the highest incidence of psoriasis and the lowest incidence of atopy among first degree relatives. The converse incidence was found in the seborrhoeic group. It is suggested that infants who develop psoriasiform napkin dermatitis have a psoriatic diathesis.
