Quantitative and detailed 3-dimensional (3-D) morphological information can be obtained from the same tissue volume using a confocal laser scanning microscope (CLSM). In the present study, we used CLSM for evaluation of Langerhans' cells (LC) in human skin at 0 h, 24 h and 48 h following occlusion with patch tests for 48 h. The relative volume of epidermal CD1a reactivity was quantified with CLSM ...

Warts and skin tumours are common in renal transplant recipients (RTR). The increased susceptibility to skin lesions has been attributed to immunosuppressive treatments. The epidermal antigen-presenting Langerhans' cell (LC) is important for cutaneous immunosurveillance. The number of LC is reduced by UV light and by immunosuppressive therapy. One hundred and seventy-three immunosuppressed patient ...

Two commercially available electrical instruments which evaluate the hydration state of the skin surface were compared in in vitro and in vivo experiments. The skin surface hygrometer (Skicon-200) employs high-frequency conductance, whereas the corneometer (CM 420, CM 820) uses electrical capacitance to determine the level of hydration. In a simulation model of in vivo stratum corneum (SC), the hi ...

Bulk sample x-ray microanalysis (XRMA) of human gluteal skin was performed to provide data on water and ion profiles over the epidermal cross section. All samples were analyzed both in the frozen hydrated state and in the frozen dried state. This allows, for the first time, a quantitative determination of the local water content in different strata of the skin. A steep water gradient was found in ...

Vertical cutaneous extensibility was studied before and after 1, 2, 5 and 10 min hydration by application of tap water. After hydration, we noted an increase in all rheological parameters linked to elasticity whereas viscosity and hysteresis parameters were unmodified. These modifications took place from the first minute and increased thereafter. Men and women showed identical values prior to hydr ...

An endocrinological study of 15 psychiatric patients with primary cutis verticis gyrata (CVG) and 7 control patients was carried out. The investigation of the pituitary-gonadal axis, pituitary-adrenal axis, pituitary-thyroid axis, prolactin and human growth hormone (basal values and circadian biorhythms) did not show any significant difference between the CVG and the control patients. Only levels ...

The initiation of the antihistamine effect of a single dose of acrivastine (8 mg) or cetirizine (10 mg) on wheals and itch induced by histamine dihydrochloride (10 mg/ml) in the prick test was studied in a randomized cross-over design employing 20 healthy medical students. The prick test was performed before ingestion of the drug and after 15, 20, 25, 30, 60 and 90 min and 2, 3 and 4 h. Local symp ...

The present study demonstrated human papillomavirus (HPV) infection by means of an in situ HPV DNA hybridization screening test (BIOHIT) in 8 male patients with genital condyloma acuminatum, their asymptomatic female consorts and 6 female patients with vulval condyloma acuminatum. The investigations revealed that all but one of the female consorts were infected by HPV but did not show any clinical ...

Eight patients with progressive systemic sclerosis were treated with photopheresis or extracorporeal photochemotherapy given on 2 consecutive days every 4 weeks for 5 to 8 months. Previous treatment with immunosuppressive agents or D-penicillamine was discontinued for at least 4 weeks prior to photopheresis. Although IL-2 receptor density in peripheral blood T-lymphocytes decreased significantly i ...

Additives are used widely to enhance the quality of food products. To identify possible phototoxic properties, 13 food additives (benzoic acid, sodium benzoate, 4-hydroxybenzoic acid, 4-hydroxybenzoic acid methyl ester, 4-hydroxybenzoic ethyl ester, 4-hydroxybenzoic acid propyl ester, p-hydroxybenzoic acid n-butyl ester, benzyl alcohol, sorbic acid, potassium sorbate, propionic acid, sodium disulf ...

The induction of type IV hypersensitivity to contact allergens in guinea pigs has been studied by using allogenic peritoneal exudate cells (> 90% macrophages), which had been incubated primarily in vitro with dinitrochlorobenzene, formaldehyde, potassium dichromate, nickel II sulphate or para-aminobenzoic acid. In these guinea pig sensitization experiments Freund's complete adjuvant was used. In a ...

The assessment of cell proliferation is important to our understanding of hyperproliferative disorders. In this work we evaluated the proliferation characteristics of epidermal keratinocytes in diseases with abnormal keratinization by two different methods (immunostaining for the proliferating cell nuclear antigen--PCNA and histochemical staining for nucleolar organizer region--associated argyroph ...

The scanning electron microscope has been used to examine scales taken from the scalp of 3 patients with pityriasis amiantacea alone, 3 psoriatic patients with pityriasis amiantacea and one patient with both atopic dermatitis and pityriasis amiantacea. Samples from 2 patients were additionally studied by different fixation techniques and in the frozen hydrated state, but no cementing of the scales ...

A case of acanthosis nigricans associated with a metastatic adenocarcinoma is presented. To our knowledge this is the first one reported in the literature. The primary tumour is unknown, but it is presumably a cholangiocarcinoma. The skin changes preceded the detection of malignancy by 2 years, during which the skin lesions progressed though the patient was still in good health. If malignant acant ...

This is the first reported case of neutrophilic dermatosis of the face (Sweet's syndrome) associated with aortitis syndrome (Takayasu arteritis) and Hashimoto's thyroiditis. The patient was a 39-year-old Japanese female for whom corticosteroid therapy was effective.

A patient with drug-induced toxic pustuloderma is presented. The patient, who was asthmatic and who was being treated with ofloxacin for bronchitis and pharyngitis, developed intense erythemas followed by subcorneal pustulation associated with fever and a neutrophil leukocytosis. The diagnosis was confirmed by oral readministration of ofloxacin, with the result that pustular eruptions were induced ...

In an open study with identical criteria for diagnosis, 16 female patients with typical symptoms of chronic vulvodynia associated with acetowhitening of the vestibular epithelium and koilocytosis in biopsy specimens received recombinant interferon alpha-2b 5 MIU intralesionally 3 times weekly for 3 weeks or subcutaneously 3 times weekly for 8 weeks. Three months after end of therapy, clinical symp ...

The long-term effects of psoriasis heliotherapy were studied in a randomized cross-over trial with a 2-year follow-up. We allocated 95 patients randomly to receive a 4-week heliotherapy course, either at the onset or in the middle of the follow-up period. After a highly significant immediate alleviation of psoriasis about 50% of the patients still had a reduction of psoriasis 6 months later and ab ...
