Validation of the diagnostic criteria for atopic dermatitis.

OBJECTIVE: To validate the accuracy of newly proposed diagnostic criteria for atopic dermatitis (AD). DESIGN: Double-blind, cross-sectional study comparing the achievement of new criteria with the diagnosis of a dermatologist. SETTING: A private, general dermatology, outpatient clinic. PATIENTS: A sample of 416 consecutive patients attending the clinic within 2 months (146 males and 270 females), consisting of 60 patients with AD and 356 control patients with other skin diseases. MAIN OUTCOME MEASURES: Sensitivity, specificity, and positive and negative predictive values of proposed criteria in the diagnosis of AD. RESULTS: Sensitivity, specificity, and positive and negative predictive values of proposed diagnostic criteria for AD were 10.0% (95% confidence interval [CI], 4.1%-21.2%), 98.3% (95% CI, 96.2%-99.3%), 50.0% (95% CI, 22.3%-77.7%), and 86.6% (95% CI, 82.8%-89.7%), respectively. CONCLUSIONS: These diagnostic criteria for AD are highly specific and are suitable for clinical trials. However, they may not achieve enough sensitivity to be useful for large, population-based epidemiological studies or for routine clinical practice, at least in Iran.

Identical MHC markers in non-Jewish Iranian and Ashkenazi Jewish patients with pemphigus vulgaris: possible common central Asian ancestral origin.

Previous studies showed that almost all Ashkenazi Jewish patients with pemphigus vulgaris carried the extended haplotype [HLA-B38, SC21, DRB1*0402, DQB1*0302] or [HLA-B35, SC31, DRB1*0402, DQB1*0302] or class II fragments of them. Non-Jewish patients carried [HLA-B55, SB45, DRB1*1401, DQB1*0503] or its class II fragments. In the present study of 20 Iranian patients with pemphigus vulgaris, 17 were found to carry DRB1*0402, DQB1*0302 haplotypes, also found among normal Iranian haplotypes and the same as that of the Jews. These findings suggest that the pemphigus MHC susceptibility gene among Iranians derived from the same ancestor as that in the Ashkenazim. The ancient Jews were under Persian domination from 500 B.C. until 300 B.C. and in the 8th century A.D., a Tataric people living in the kingdom of Khazar on the Western shore of the Caspian Sea and the Northern shore of the Black Sea, near Persia, converted to Judaism, providing possible opportunities for gene mixing in two populations that are distinct and separate today.

Granuloma faciale: successful treatment of nine cases with a combination of cryotherapy and intralesional corticosteroid injection.

BACKGROUND: Granuloma faciale is a rare disorder characterized by asymptomatic papules, nodules, and plaques on the face. Although the exact pathogenesis of this disease in unclear, it is considered a variant of leukocytoclastic vasculitis confined to the skin. Several medical and surgical methods have been used to treat it with variable results. CASE REPORTS: We report nine cases of granuloma faciale treated with a combination of cryotherapy with liquid nitrogen and intralesional injection of corticosteroids. RESULTS: The lesions cleared completely in all of the patients without any side-effects. No recurrences have been observed. CONCLUSIONS: Cryotherapy with liquid nitrogen, followed by intralesional injection of corticosteroids, is a safe and effective method to treat granuloma faciale.

Benefits and risks of intralesional corticosteroid injection in the treatment of dermatological diseases.

Intralesional corticosteroid (CS) injections have been used to treat a variety of dermatological and non-dermatological diseases with variable results. The purpose of the injection is to attain a high concentration of the drug at the diseased site, with minimal systemic absorption. Several CS preparations are available for intralesional injection, although triamcinolone derivatives have gained the widest usage in dermatology. The dose and the interval between injections depend on the type, size and severity of the lesion as well as the response to the previous injections. The most critical issue in the efficacy and also in the development of complications of the injections, is the method of injection. Several local and systemic side-effects have been reported following intralesional injections, but most of them are rare or acceptable. Thus intralesional CS injection is an integral part of the clinical practice of dermatology. Since their introduction in 1951, intralesional CS injections have become an integral part of clinical practice in dermatology. They are used alone or in combination with other therapeutic modalities in the treatment of many skin diseases. The purpose of the injection is to attain a high local concentration of the CS at the diseased site, without significant systemic absorption, thus avoiding the numerous side-effects associated with systemic administration. Intralesional CS injection may be a valuable therapeutic modality in situations where topical CS are not suitable for use, either because of low potency and inefficient epidermal barrier penetration or in clinical conditions associated with epidermal atrophy.

Prevalence of autoimmune diseases in the family members of patients with pemphigus vulgaris.

BACKGROUND: Several studies show that the family members of patients with autoimmune diseases are more susceptible to the development of the same or, more frequently, other autoimmune diseases. Although an association between pemphigus vulgaris (PV) and other autoimmune diseases has been reported, the presence of autoimmune diseases in the family members of patients with PV has not been studied. OBJECTIVE: The purpose of this study was to determine whether first-degree relatives of patients with PV are more susceptible to the development of autoimmune diseases. METHODS: A case-control study was done. A total of 830 first-degree relatives of 60 white patients with PV were compared with 890 relatives of 60 age-, race-, and sex-matched random controls. Both groups of relatives were screened for the presence of 16 autoimmune diseases. RESULTS: There was a highly significant increase in the prevalence of autoimmune diseases in the first-degree family members of PV patients, compared with controls. CONCLUSION: There is an increased susceptibility to the development of autoimmune diseases in the family members of patients with PV.
