The monoclonal antibody Ki-67 was used to determine the numbers of cycling cells in hair follicles both in alopecia areata and in normal scalp skin. Pronounced nuclear staining was limited to the area below the critical line of Auber and the exterior part of the outer root sheath. In alopecia areata there is reduced nuclear Ki-67 binding in the bulb of anagen hair follicles. These findings indicat ...

Interleukin-6 (IL-6 or BSF-2/IFN beta 2) is a component of normal human skin. IL-6 was immunologically detected in basal keratinocytes, endothelial cells and in a number of mononucleated cells and fibroblasts in normal skin and sudoriparous ducts. In psoriasis, intense labelling of the cytoplasm in the vicinity of keratinocyte membranes was detected in all epidermal layers and other skin appendage ...

Integrins are cell surface molecules of importance in a wide variety of cellular functions, including morphogenesis, cell migration and cell matrix interactions. The beta-2 (B2) integrin (leukocyte integrin, CD11/CD18) subfamily comprising three members, each consisting of a shared beta subunit (CD18) non-covalently associated with unique alpha subunits (CD11a, CD11b, CD11c). In the present study, ...

A female presenting multiple osteoma cutis lesions without underlying endocrinological disturbance was studied. Histologically, lesions revealed true bone formation with multiple osteoblastic cells. This was confirmed by demonstrating high alkaline phosphatase activity and osteonectin expression in osteoma cutis lesions. Interestingly, tenascin and type III procollagen were in close association to ...

The number in and distribution of Langerhans' cells were studied in 11 patients with a maculopapular drug eruption. The Langerhans' cells (LC) were identified with a monoclonal antibody to OKT6 antigen, by employing an immunofluorescence technique. Skin biopsies were taken from lesional and non-lesional skin during the acute stage of the disease. LC in the lesional biopsies increased in number by ...

On the basis of a recent report that minocycline is effective in the treatment of acne inflammation by acting directly as an antioxidant on infiltrating neutrophils, we investigated whether doxycycline might also be capable of reducing the generation of reactive oxygen species, using human neutrophils and a cell-free, xanthine-xanthine oxidase system. The species investigated are superoxide radica ...

We describe 2 patients who injected themselves with the same brown heroin a few days before hospitalization. The first patient presented with characteristic oculo-cutaneous candidiasis. Blood samples remained sterile during the so-called 'septicemic syndrome' which represents the first phase of this syndrome and were positive for Candida albicans only when cutaneous nodules developed. The second p ...

A 43-year-old homosexual man with the Acquired Immunodeficiency Syndrome (AIDS) developed cutaneous molluscum contagiosum-like lesions on face, ears, neck, hands and feet. He was admitted to our unit with fever, malaise and headache. Cytologic examination of skin brushing revealed numerous encapsulated budding yeasts, identified as Cryptococcus neoformans. Such a finding calls for a cytologic exam ...

Genital papilloma virus infection (GPVI) is in many patients a longlasting, relapsing disease for which no effective treatment is available. This fact and the association between the virus and cancer puts much stress on the afflicted patient. Of 41 men with GPVI interviewed, 17 (40%) reported a negative effect of the disease on their sexual life. Most distressing was the fear of transmitting the d ...

Children aged 0-21 years, 60 children with atopic dermatitis (AD), 40 children with rhinoconjunctivitis and or asthma (RA) and 40 children with no atopic history (HC) were studied to evaluate the relationship between skin colonisation with Pityrosporum ovale and the occurrence of specific IgE antibodies to P. ovale. The following studies were done: culture for P. ovale, measurement of IgE antibodi ...

We investigated immediate and delayed hypersensitivity to birch pollen in 10 patients with atopic dermatitis (AD) who had experienced a worsening of their eczema during the birch pollen season. The patients were prick- and patch-tested and antigen-induced basophil histamine release and lymphocyte proliferation were measured. 9/10 birch pollen-allergic patients proved positive in the histamine rele ...

The effects of one week's daily treatment with dexchlorpheniramine (3 + 3 mg x 2) and loratadine (10 mg x 2) on the cutaneous reactions to putative mediators of urticarial reactions were studied in healthy subjects and in patients with chronic urticaria. Biopsy specimens were taken from skin with delayed reactions and studied immunohistochemically for the presence of eosinophilic cationic protein ...

We report a case of allergic granulomatosis and angiitis of Churg-Strauss. The patient is a 40-year-old woman who satisfied the clinico-pathological triad of asthma, tissue and blood eosinophilia, and granulomatous vasculitis. We also measured serum eosinophil cationic protein (ECP) levels in this patient. In the active stage, the serum ECP level was higher than in healthy controls, declining in t ...

The development of red nail lunulae has been extremely rarely described in alopecia areata. We observed 2 patients, a 30-year-old woman and a 61-year-old man, both suffering from severe alopecia areata, and having red lunulae. The colour changes, which developed a few weeks after the acute onset of hair loss, disappeared slowly, leaving horizontal fissures (Beau's lines).

The authors report 3 patients affected by psoriasiform acral dermatitis, a distinctive clinical entity characterized by a chronic dermatitis of the terminal phalanges, associated with marked shortening of the nail beds of the affected fingers. The skin biopsy showed in all cases the pathological features of a subacute spongiotic dermatitis. X-ray examination of affected fingers showed no bone or s ...

Risk factors for infectious eczematoid dermatitis (IED) were analyzed in a study of males aged 19-50 years. The subjects were 43 IED patients and 226 controls with other skin diseases from the dermatological outpatient clinics of three University Hospitals in Finland. The patients' lifestyles were assessed by a self-administered questionnaire pertaining to two specified periods: the period 12 mont ...

Four infants with neonatal lupus erythematosus who had annular erythema on the trunk and face reacted positively to tests for anti-Ro(SS-A)/La(SS-B) antibodies. Electron microscopic examination of vascular endothelial cells in the annular erythema revealed the presence of tubuloreticular structures. Once anti-Ro(SS-A)/La(SS-B) antibodies had turned negative, these tubuloreticular structures were n ...

With the advent of non-fluorinated double esters the spectrum of topical dermatotherapy with glucocorticoids seems to have broadened to include safer congeners. To assess the atrophogenicity potential of glucocorticoids, high-frequency ultrasound has been proposed. In a comparative trial using the DUB 20 system, 24 healthy volunteers applied hydrocortisone aceponate, the corresponding vehicle, pre ...

Serum levels of vitamin D metabolites were determined in 11 patients treated for cystic acne with a four-month course of isotretinoin (Roaccutane). The levels were measured before treatment and after two months of medication. We found a significant fall in the level of 1,25-dihydroxyvitamin D (p less than 0.01) and a significant increase in the molar ratio of 24, 25-dihydroxyvitamin D to 25-hydrox ...

Delayed hypersensitivity retest reaction 3 and 6 weeks after induction of allergic and irritant inflammation, was studied in 13 females with known hypersensitivity to nickel. An increased retest reaction compared to controls was observed only in sites of earlier specific allergic inflammation. Also a general down-regulation of the degree of hypersensitivity was observed at retesting.

The inhibition of erythema by drugs applied topically after irradiation with 0.2-0.8 J of 313 nm has been studied in healthy volunteers. Indomethacin and piroxicam markedly inhibited the erythema at 6 to 24 h after irradiation but erythema reappeared at 45 h. The results reported suggest that the UVB response is biphasic with an early phase responsive to nonsteroid anti-inflammatory drugs and a la ...

Questionnaires concerning nursing care of leg and foot ulcer patients in three major care-giving sectors of the national health service, namely the Department of Dermatology, general hospital wards/clinics, and primary care, have been analysed. The overall response rate was 88% (primary care: 100%). Forms regarding 193 patients with leg ulcers and 64 patients with foot ulcers were analysed. Substa ...

By means of a questionnaire sent to all medical units in Malmö, including primary care, homes for the elderly, and industrial health clinics, 275 patients with leg and foot ulcers were identified. With a population of 232,908 in Malmö, this corresponds to a prevalence of 0.12%, which is lower than reported by others. Since the response rate was high (88% total, Primary Care: 100%), the prevalenc ...

A noninvasive Finn Chamber sampling method and HPLC analysis were used to determine epidermal urocanic acid (UCA) concentrations of psoriasis patients during 4 weeks of heliotherapy on the Spanish Canary Islands and a follow-up period of 8 weeks. During heliotherapy the epidermal cis-UCA concentration increased from a mean initial value of 0.2 nmol/cm2 to a mean final value of 2.9 nmol/cm2. The to ...
