Infantile seborrhoeic dermatitis is a dermatosis affecting infants characterized by little or no itching and by completely typical skin symptoms, distribution and evolution. Infantile seborrhoeic dermatitis should therefore be differentiated from atopic dermatitis and from diaper-rash although interferences be possible. In fact the high frequency of the atopic dermatitis and of diaper rash may cause these two manifestations to sometimes superimpose on infantile seborrhoeic dermatitis. This in turn causes rather complex clinical situations that may be very hard, but not impossible to diagnose if use is made of laboratory findings to support clinical features. The pathogenesis and etiology of infantile seborrhoeic dermatitis are still debated although recent results assign the dominant role to Candida albicans. This mycete also plays a relevant role in the genesis of diaper rash and particularly of Leiner's exfoliative erythrodermas, which can be interpreted as a generalized and erythrodermic expression of infantile seborrhoeic dermatitis. Systematic cultural investigations and appropriate antimycotic treatments, that would stimulate antibody response, will allow to clarify in the near future this interesting etiological problem, with important therapeutical consequences.

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.

201 patients with skin problems caused in their own opinion by working with visual display terminals (VDTs) were referred and examined. 18% claimed that their condition improved overnight and 21% that it did so over the weekend. In 25 patients, the skin problems occurred mainly on the cheek turned towards the VDT. Half the patients had rosacea, but their subjective skin symptoms were generally more severe than those in ordinary cases of rosacea, i.e., severe pain, itching and burning. The rest of the patients mainly had common facial dermatoses such as seborrhoeic eczema, acne vulgaris and atopic dermatitis. The patients' skin types, judged by their response to ultraviolet light, did not differ from those of a control population. 18% had non-specific skin problems, e.g., itching and redness. This latter group of patients most closely resembles those cases previously described amongst VDT-workers. An attempt to correlate skin problems with VDTs' electrostatic field strength was unsuccessful because of difficulties in eliminating it. Of 52 electrostatic shields placed in front of patients' VDTs, 38 were defective and 9 were wrongly earthed. The prevalence of migraine-like headache was 40%, which is much higher than in a control population. There was no great use of cosmetics by the study population. When followed up after an average of 8 months, 2/3 of the patients had fewer skin complaints. The question of whether the prevalence of skin problems in general is higher amongst individuals using VDTs than in a control population is addressed in a current study.

We performed clinical trials to evaluate the therapeutic effects of Foltene in patients of the several types of hair fallings. Thirty patients with male pattern baldness, alopecia areata and seborrheic alopecia were included in this study. Foltene was applied every other day for 40 days, and followed by maintenance therapy of twice application a week. The duration of whole therapy was 6 months. We conclude that Foltene is an effective and agent for male pattern baldness, alopecia areata and seborrheic alopecia from the following results. Ten patients with male pattern baldness was treated with Foltene for 6 months. Foltene had therapeutic effects of 50% in hair regrowth, 70% in decreased hair falls, 30% in decreased dandruff, 50% in decreased seborrhea. Thirteen patients with alopecia areata was treated with Foltene for 6 months. Foltene had therapeutic effects of 61.6% in hair regrowth, 53.9% in decreased in hair falls, 53.9% in decreased dandruff, 77.0% in decreased seborrhea. Seven patients with seborrheic alopecia was treatment with Foltene for 6 months. Foltene had therapeutic effects of 85.8% in hair regrowth, 57.2% in decreased hair falls, 42.9% in decreased dandruff, 85.8% in decreased seborrhea. The degree of therapeutic success was related to the duration of therapy. The side effects were as followed: itching sensation developed in 2 patients (6.7%); tingling sensation in 3 patients (10.0%); burning sensation in 1 patient (3.3%); erythema in 3 patients (10.0%).

In an attempt to provide clinically relevant data regarding both dermatologic disease and skin care needs in the elderly, 68 noninstitutionalized volunteers, aged 50 to 91 years (average age, 74 years), were enrolled in a study consisting of a 33-item questionnaire and a total cutaneous examination. Two thirds of the entire group and 83% of the 23 octogenarians reported medical concerns regarding their skin, with pruritus as the most frequent complaint. On examination, all subjects had at least one cutaneous abnormality, and symptomatic and/or medically significant disorders were present in 64.7%. In decreasing order of prevalence, disorders for which dermatologic therapy was judged desirable included actinic keratoses, tinea pedis, contact dermatitis, seborrheic dermatitis, stasis dermatitis, and skin cancer. Overall, there was rather poor correlation between the subjects' complaints and perceptions and objective physical findings. Further, despite a high prevalence and long average duration of dermatologic concerns, very few subjects had consulted a physician for these problems, and no complaints other than "rashes" and pruritus had ever been discussed with any health care professional. Review of skin care regimens revealed substantial limitations with regard to bathing, shampooing, and nail care, particularly for subjects aged 80 years or older. Despite a small sample size and possibility of selection bias among the subjects, these data strongly suggest that skin problems are common among the elderly and that at present their dermatologic needs are largely unmet.

A randomized double-blind placebo-controlled cross-over study was made of ketoconazole 200 mg daily in nineteen patients with seborrhoeic dermatitis. All had scalp lesions and sixteen had seborrhoeic dermatitis at other sites. Responses were measured by clinician and patients independently, using a linear analogue scale. Body and scalp lesions and itch regressed considerably and significantly with ketoconazole in all but five patients, three of whom subsequently responded to a higher dose. The patients studied with seborrhoeic dermatitis had been sent by their family doctors in answer to a request for patients with dandruff, and the clinical difference between the two was found to be only of degree. Three patients with dandruff without erythema were studied separately using the same study design: all three responded similarly to those with seborrhoeic eczema. It is concluded that Pityrosporum yeast infection is the immediate cause of seborrhoeic dermatitis and that dandruff is its mildest manifestation.

In a prospective study of thirty-seven infants presenting with dermatitis in infancy it was found that pruritus, a positive family history of atopy, and the age of onset of skin lesions were of little value in distinguishing atopic dermatitis from infantile seborrhoeic dermatitis. The most useful distinguishing features were the increased incidence of lesions on the forearms and shins in atopic dermatitis, and in the axillae in infantile seborrhoeic dermatitis. The onset of skin lesions solely in the napkin area favoured a diagnosis of infantile seborrhoeic dermatitis, but when more than one site was involved the distinction was less clear. Infantile seborrhoeic dermatitis carried a much better prognosis than atopic dermatitis. In thirty-six out of thirty-seven infants the definitive diagnosis could be made with confidence on clinical grounds by the age of I year, but was often difficult at first presentation in early infancy.

The systemic complications of therapy with lithium are well known, but toxidermia has only been recognised since 1968. The carbonate (Teralithe) is the lithium salt which is mainly responsible, leading to minor dermatoses: oedema, pruritus, alopecia, urticaria, purpura, allergic vasculitis, pretibial ulceration. Some more specific conditions have been individualised by their severity and rarity: acne form eruptions, seborrheic dermatitis, follicular keratoses and psoriasis-like dermatosis as well as true psoriasis induced or aggravated by lithium. The authors review the literature and discuss the pathogenesis of these toxidermias. The cause of some dermatoses can be explained, especially the allergic vasculitis and psoriasis lesions. The underlying mechanism of most of these conditions remains unknown, but excessive tissue concentrations of the drug probably play an important role in inducing these complications.

An alkaline whole coal tar shampoo has been clinically re-evaluated for its therapeutic and cosmetic properties. Its efficacy, as anticipated, is confirmed in psoriasis, dandruff, seborrheic dermatitis, and pruritus. Scanning electron microscopy reveals the whole coal tar shampoo's ability to repair hair similar to protein cosmetic shampoos. Body, luster, and manageability improved throughout this eight week study. A new shampoo action was recorded, described as "corrective;" both oily-haired and dry-haired persons simultaneously exhibit substantial improvement towards the norm. It is postulated that the alkaline-whole coal tar shampoo stimulates natural corrective mechanisms.

Acquired immunodeficiency syndrome was first recognized as a new disease in 1981 because of the unusual association of Kaposi's sarcoma and Pneumocystis carinii pneumonia in young men. The skin remains one of the most important clinical markers for acquired immunodeficiency syndrome, now recognized as the end stage of infection with the human immunodeficiency virus (HIV). Indeed, an urticarial viral exanthem appearing during seroconversion may allow early identification of newly infected individuals who might benefit from administration of antiviral therapy during plasma viremia. The "asymptomatic HIV infection" is often accompanied by multiple skin complaints, which commonly include xerosis, pruritus, psoriasis/seborrheic dermatitis, and pruritic papular eruptions, the cause of which remains controversial. Psoriasis and Kaposi's sarcoma lesions share features including angiogenesis, dermal dendrocytes infected with HIV, and epidermal hyperproliferation, and are manifested by mice transgenic for HIV provirus or Tat-ltr. Changes in the immune system including T-cell function, antigen response, and shifting cytokine expression as well as a propensity for autoimmune reactions must underlie the skin immunodysfunction occurring in the setting of HIV infection. One of the most unsettling controversies suggested by in vitro data is that ultraviolet light, an effective therapy for HIV-related skin disorders, may actually activate the virus.
