The Internet is increasingly important for doctors in all branches of medicine, but to what extent it is used by dermatologists is not known. In May 2001, we sent a questionnaire by post to 1,291 members of the dermatological societies of the United Kingdom, Sweden, and Norway. Six hundred fifty-three (51%) responded. Excluding those from retired doctors(More)
BACKGROUND Epidemiological data and the effect of sun exposure on atopic eczema (AE) suggest that vitamin D (vitD) may be involved in the pathogenesis. OBJECTIVES To investigate if vitD levels were associated with the presence or severity of AE in the first 2 years of life in children living in south-east Norway. METHODS Infants, recruited to a clinical(More)
BACKGROUND We have explored continuing medical education among Norwegian dermatologists, especially their use of medical journals and the Internet. MATERIAL AND METHODS In April 2001, a questionnaire was sent to 170 dermatologists, including junior doctors in specialist training. 129 questionnaires (76%) were returned, of which 16 were excluded from the(More)
Keratoacanthomas are commonly occurring benign skin lesions localized to sun-exposed areas. They typically develop rapidly and may show cellular atypia and infiltration like cutaneous squamous cell carcinomas, but they finally regress spontaneously. This benign lesion shows a high degree of genetic instability as assessed by comparative genomic(More)
Non-melanoma skin cancer is frequent in organ transplant recipients. The risk of posttransplant cutaneous squamous cell carcinoma in Norwegian heart transplant recipients (n = 148) and kidney transplant recipients (n = 1020) on triple immunosuppressive therapy with cyclosporine, azathioprine, and prednisolone, transplanted between 1983 and 1992, were(More)
Folliculotropic mycosis fungoides is a variant of cutaneous T-cell lymphoma with distinct clinicopathological features. We describe here the clinical presentation, pathology findings and treatment outcome in 15 Norwegian patients. All patients were diagnosed between 1997 and 2010 at Oslo University Hospital. A spectrum of skin lesions, both typical and(More)
Atopic eczema (AE) is associated with Staphylococcus aureus (S. aureus) colonization and skin barrier dysfunction, often measured by increased transepidermal water loss (TEWL). In the present study, the primary aim was to see whether S. aureus colonization in the vestibulum nasi and/or fauces was associated with increased TEWL in infants with healthy skin(More)
BACKGROUND Basal cell carcinoma may have a locally aggressive growth pattern. This type of cancer is often located on the face and is difficult to limit clinically. Normal excision and tumour destructive treatment often lead to recurrence of the tumour. Mohs surgery is a radical technique for removing this type of lesion. MATERIAL AND METHOD This review(More)
BACKGROUND Genital erosive lichen planus (GELP) in women is a chronic inflammatory disease characterized by painful vulval and vaginal erosions. Topical photodynamic therapy (PDT) is increasingly used in premalignant and malignant diseases and may have an effect in inflammatory diseases. OBJECTIVES To assess the feasibility, efficacy and safety of hexyl(More)
