摘要:
Rosacea fulminans is a rare disease of unknown cause which occurs exclusively in women well past adolescence. It was previously called pyoderma faciale because of its confinement to the face covering most of the surface with innumerable fluctuant inflammatory nodules and papules which frequently fuse and form monstrosities. Seborrhea prior to onset is typical. It is not a pyoderma; neither it is infectious or a variant of acne conglobata. The patients respond well to a therapeutic regimen including isotretinoin in combination with topical and systemic corticosteroids. The response is superior and much more rapid than in patients treated with oral antibiotics. Rosacea fulminans is the only indication for topical or systemic corticosteroids in the treatment of rosacea. Scarring is often minimal when the lesions clear. No recurrence is seen.

摘要:
Temporary improvement of atopic dermatitis lesions may occur after acute, severe infections. One such case is shortly described, and it is then proposed that such a phenomenon may serve as an indirect evidence to support the finding of a predominant Th2 imbalance in atopic dermatitis.

摘要:
Tightly curled ‘frizzy’ hair is a pathognomonic sign of giant axonal degeneration (GAD). The present study compares the morphological structure of the scalp hair of a GAD patient with that of her parents and first-degree relatives with the aid of scanning electron microscopy. The comparison included plaited hair of two age-matched controls, in order to exclude mechanical plaiting artifacts. Trichorrhexis nodosa and fringing of the cut ends were exclusively found in the patient’s hair. Longitudinal grooving was also frequently seen in hair of normal persons. Assay of carbon (C), sulfur (S) and nitrogen (N) contents of the patient’s hair was normal, but the S:N ratio was significantly reduced, as compared with her relatives. However, comparison with a control group of non-related healthy volunteers showed no dif

摘要:
Most quantitative in vitro approaches to determine irritancy have examined the potential of compounds to decrease biological functions or inhibit growth of cells. Irritants, however, are known to generally have the opposite effect in vivo, i.e. to stimulate cell division. This property has not been directly studied in vitro. We examined the ability of sublethal concentrations of sodium lauryl sulfate (SLS) to stimulate cultured keratinocyte and fibroblast proliferation in vitro. The growth of keratinocytes, without added growth factors, continuously exposed to SLS for 4 days was stimulated approximately 89% compared to control. Keratinocytes exposed to SLS for 1 or 18 h were stimulated 36 and 12%, respectively, over the next 4 days of growth. Subconfluent fibroblasts were also stimulated approximately 38%. Confluent fibroblasts were stimulated 40%. All stimulations were maximal between 10––8 and 10––5M added SLS. Media conditioned by keratinocytes exposed to 10––8M 10––5M inhibited cell growth. We conclude that sublethal doses of SLS can stimulate the growth of cultured keratinocytes and fibroblasts. The stimulation of growth seen may be related to the stimulation observed in in

摘要:
In the past, several authors described an association of vitiligo with autoimmune disorders and the presence of different tissue autoantibodies. A review of the literature showed large differences in the results. Therefore, 321 patients with vitiligo (male/female ratio 114/207) were examined to see whether the frequencies of associated diseases and phenomena (i.e. Koebner phenomenon, canities praecox, halo nevi, poliosis circumscripta), the number of pigmented lesions and the presence of autoantibodies are of significance in order to support (a) a subentity of childhood vitiligo and (b) whether there is a true predisposition or association of autoimmune or other diseases in this group of patients. The data confirm earlier results of a prevalence of thyroid disease and the presence of thyroid antibodies, whereas other diseases are a random event. 6.2% of the patients had congenital nevi compared with 2.8% in a normal healthy population. Based on the results of this study and the significant higher risk for development of melanomas in this patient group, an annual checkup is recommended.

摘要:
Over 20 months, we have treated 74 patients (59 children less than 12 years of age) with port-wine stains (PWS) using a 585-nm flashlamp-pulsed dye laser (SPTL-1, Candela Corp., Wayland, Mass., USA) after topical anesthesia with EmlaTM cream. A 5-point reference color scale was used to evaluate the results. 45 patients had at least one treatment on the entire surface of the lesion. A mean of 88 impacts per session was delivered. There was a significant decrease in color in around two thirds of the cases after one complete treatment with a gradual tendency to improvement after subsequent treatments. Younger age at the beginning of treatment was not found to be predictive of a better outcome after the first treatment. In around one third of the cases, positive test site treatment was not correlated with significant improvement after one treatment. Lesions situated on the limbs were less responsive than those on the head and neck. Except for problems due to absence of general anesthesia in young children enduring repeated stressful and sometimes painful procedures, the overall impression is that early treatment of PWS is possible with very limited risks of scarring using this technique.

摘要:
Paraneoplastic pemphigus (PNP) is a form of pemphigus considered to bear characteristic immunohistopathological features (vacuolar-interface dermatitis, keratinocyte dyskeratosis and reactivity of patients’ sera with transitional epithelia). The present study was undertaken in order to investigate whether these criteria are specific enough so as to allow the diagnosis of PNP in the absence of clinical data. A retrospective study of 66 biopsies of pemphigus revealed that one third of them comprised histological signs of PNP; one of the corresponding sera reacted with mouse bladder epithelium. However, no evidence of a neoplastic disease was present in any of the patients, and Western blotting further excluded the diagnosis of PNP. These results suggest that some of the features considered characteristic of PNP are not strictly specific for this variety of pemphigus; hence this diagnosis cannot be reliably established by histology or immunofluorescence but requires biochemical studie

摘要:
Image analysis of videographs of nail fold capillaries was performed in patients with systemic sclerosis (SS), and the capillary patterns were defined by canonical discriminant analysis. Forty-eight of 55 SS patients were significantly differentiated from patients with systemic lupus erythematosus and normal controls. Normal controls and patients with systemic lupus erythematosus showed identical nail fold capillary patterns; in patients with dermatomyositis the pattern was similar to that of SS. The canonical discriminant analysis revealed that only 5 of 55 (9%) SS patients showed a normal capillary pattern. The abnormal capillary pattern in SS patients correlated with microvascular disturbances such as Raynaud’s phenomenon, digital pitting scars and low finger temperature. Our results indicate that quantitative analysis of the nail fold capillaries is useful in evaluating the microvascular disturbances in SS patient

摘要:
Genetic polymorphisms in HLA-A, -B, -C and -DR antigens were investigated in 78 unrelated Japanese patients with palmoplantar pustulosis (PPP) and compared with a total of 472 normal persons. Only HLA-DR9 showed a significantly increased frequency among all HLA antigens investigated (χ2 = 11.57, p < 0.001). It is suggested that major histocompatibility complex class II antigens including HLA-DR antigen may determine the susceptibility to PPP and PPP may be a distinct disease entity from psoriasis
