Peptide T, the HIV envelope-derived fragment Ala-Ser-Thr-Thr-Thr-Asn-Tyr-Thr, has already been used to successfully treat psoriatic patients without major side-effects. The underlying reason for the positive effect is, however, at present unknown. In the following minireview, we summarize today's knowledge regarding peptide T's interaction with other chemical messenger molecules, such as somatosta ...

Moisturizers and emollients do not only smooth the skin but also make it more supple. To clarify this effect, the short-term influence of tap water, paraffin oil, ethanol and glycerin on skin mechanics was studied. These substances are all common ingredients in moisturizers and emollients. Significant changes were seen already after 10 min of application. The distensibility and hysteresis (creep p ...

Among the factors that control the survival of microorganisms on human stratum corneum are skin lipids, including sphingosines. Because the antibacterial spectrum of sphinganine resembles that of cell wall antibiotics, electron microscopy of sphinganine-treated and untreated S. aureus was performed; the lipid induced multiple lesions of cell wall, membrane evaginations and loss of ribosomes. Howev ...

GM1-gangliosidosis (GM1) is one of the metabolic storage diseases, of which a differential diagnosis requires an array of biochemical assays to determine the enzyme deficiency. This approach is not only time-consuming and costly but also unavailable to most hospital laboratories. However, a presumptive diagnosis of GM1 may be made on the basis of coarse facial feature, foamy endothelial cells in t ...

Fourteen patients with hereditary palmoplantar keratoderma of the Unna Thost variety were included in the study. Dermatophytosis was found in 7 of the 14 patients. Six were affected with T. rubrum and one with T. mentagrophytes. The growth pattern of dermatophytes in keratin from the patients did not differ from that of normal control individuals. Keratin from patients with hereditary palmoplantar ...

The epidermis overlying 2-8% of dermatofibromas shows basaloid proliferations that are indistinguishable from superficial basal cell carcinoma. It is well established that basal cell carcinomas uniformly exhibit a strongly reduced expression of HLA class I molecules. Nineteen dermatofibromas with overlying basaloid proliferations were studied by immunohistochemistry using a monoclonal antibody aga ...

The effect of solar exposure during a one-week sunbathing vacation in May at 29 degrees N latitude was investigated in 22 volunteers. The following end-points were measured before and after the holiday: skin reflectance at 507 nm, transmission of radiation from 289 nm to 448 nm through the epidermis, epidermal thickness, minimal erythema dose (MED), total white cell, neutrophil, lymphocyte, and ly ...

Chloroquine is known to bind strongly to melanin and is accumulated in the skin. In dermatology, the drug is mainly used to treat photosensitivity disorders, but it has also been reported to cause sun sensitivity, especially in patients with rheumatoid arthritis. In the present study the concentrations of chloroquine phosphate in plasma and skin suction blister fluid (interstitial fluid in the ski ...

Previous studies have shown that A-gliadin, a major gluten-derived peptide known to activate the gluten-sensitive enteropathy (GSE) of coeliac disease (CD), and the non-structural E1B peptide produced during early lytic gastrointestinal infection with human adenovirus type 12 (AD12) share an identical twelve amino acid sequence. It is suggested that immunological cross reactivity between these two ...

Recently, the diagnosis of a variant form of chronic granulomatous disease (CGD) could be established in an 11-year-old girl who had been treated for atopic dermatitis for many years. In addition to severe superinfections of lesions of the skin, the following symptoms were found currently or in her history: an episode of chronic diarrhoea (suspected as lactose intolerance), an endomyocarditis, a p ...

The association between AIDS and demodicidosis has been occasionally described elsewhere. We present a new case, in a patient with post-transfusional AIDS, who had many papules and pustules localized to the upper trunk and face, in relation to zidovudine treatment.

A case of chronic urticaria is presented. The case of the disease was traced back to nickel intake by food as judged from type I and IV sensitization to nickel, a positive oral challenge test and long-standing, complete healing under a nickel-restrictive diet.

Chronic leg ulcer is a disease of long duration, occurring predominantly in elderly people. Traditionally, little interest has been devoted to the study of the impact of this disease on life quality. In the present study the Nottingham Health Profile (NHP) was used to assess disease influence on six areas of daily life, namely: pain, physical mobility, sleep, energy, emotional reactions and social ...

A case of spindle-cell carcinoma developed on a proliferating trichilemmal tumour (PTT) is presented. The tumour on the scalp of an 84-year-old white woman was excised and histological examination showed typical features of PTT, but with a coexistent malignant spindle-cell tumour with a sarcomatoid appearance. There were some areas of transition between squamous trichilemmal epithelium and the neo ...

Necrobiosis lipoidica diabeticorum is a chronic cutaneous complication of diabetes mellitus with microangiopathy as an important pathophysiologic factor. Because of the known success of hyperbaric oxygen in the treatment of chronic non-healing wounds, we used this mode of therapy to treat a diabetic patient with ulcerated necrobiosis lipoidica of 7 years' duration, refractory to medical and surgic ...

1,25-dihydroxycholecalciferol (1,25 (OH)2 D3) causes dose-dependent inhibition of fibroblast growth and collagen synthesis and has numerous immunoregulatory activities. We assessed the effects of oral 1,25 (OH)2 D3 in the treatment of patients with systemic sclerosis (SS). Eleven patients with SS entered an open prospective study. Oral 1,25(OH)2 D3 was given at a mean dose of 1.75 micrograms/day. ...

Prednisolone combined with erythromycin was given to 6 patients with cystic acne. The treatment responses were compared to those in 6 patients with cystic acne receiving isotretinoin and erythromycin and also to those in 3 patients with acne fulminans treated with prednisolone and erythromycin. During the first 4 weeks cystic acne showed a clear improvement in 5 out of 6 patients in both treatment ...

The topical anaesthetic formulation EMLA cream (eutectic mixture of local anaesthetics) is increasingly used prior to minor painful procedures performed on genital mucosa. The aim of the present study was to gain knowledge about the correlation between duration of application of EMLA and duration of analgesia. Three different application times--5, 10 and 20 min--were investigated in 12 healthy you ...

Congenital symmetrical interdigital hyperkeratosis is a rare disorder described by Frei in 1923, characterized by localized hyperkeratosis of the interdigital spaces of the hands and feet. The authors report the case of a 7-year-old girl affected by this condition. The skin hyperkeratotic lesions appeared localized exclusively to the interdigital spaces of the hands. Histologic examination showed ...

Autoimmune bullous diseases have been reported associated with different causal factors: drugs, mechanical trauma and physical trauma, particularly ultraviolet light and radiotherapy. In these cases different hypotheses regarding the pathogenesis of blister formation can be supported. In this observation, we report a localized cicatricial pemphigoid with unusual clinical presentation. Moreover, it ...

The relation between sexual practices and location of anogenital warts is discussed. Results were derived from clinical examination and interview of 56 consecutive male patients referred to CO2-laser treatment of therapy-resistant genital warts, at a clinic at the Department of Dermatovenereology, Gentofte Hospital, located in the northern area of Copenhagen. Twenty (100%) patients with anal warts ...
