Background: Exfoliative dermatitis is a rare disorder with several etiologic factors. The frequency of different etiologies varies in the medical literatures. The purpose of this study was to reveal the demographic characteristic and etiologies of exfoliative dermatitis in our department.Method: We reviewed the records of the patients who were admitted to the dermatology ward of Ghaem Hospital, Mashhad, Iran, with a diagnosis of exfoliative dermatitis in a twenty-year period (1982-2002). Age, gender, the cause of exfoliative dermatitis, and the most probable drug cause were studied. Result: Fifty-nine cases were included in the study. Male-female ratio was 1.27:1. The mean age of the patients was 50.11±19.37. The most common causes were psoriasis (40.7%), drugs (18.6%) and lymphoma (18.6%). The most common drugs that caused exfoliative dermatitis were co-trimoxazole (27.27%), carbamazepine (18.18%), and gold salts (18.18%). Conclusion: The most frequent of underlying cause of exfoliative dermatitis in our series was psoriasis. Co-trimoxazole was the most common drug that caused exfoliative dermatitis.

Background: Pemphigus is a group of autoimmune blistering skin diseases that is related to auto antibodies against desmoglein 1 and 3. Many reports have shown that HSV1, HSV2, VZV, EBV, CMV, HHV8, and HIV are triggering agents for the activation and exacerbation of pemphigus. In this study, we decided to evaluate the frequency of HSV1, HSV2, HHV8, and EBV in paraffin-embedded specimens of the new cases of pemphigus patients using immunohistochemical methods.Method: Thirty patients with pemphigus whose diagnosis was proved with direct immunofluorescens studies (20 cases of pemphigus vulgaris and 10 cases of pemphigus foliaceus) and 10 specimens from the free margins of excised melanocytic nevi were collected. Immunohistochemical staining was performed for HSV1 and EBV (using Novo Castra kit) and for HSV2 and HHV8 (using Dako kit).Result: The results showed a significance difference in the frequency of positive staining for HSV1 in skin lesions of pemphigus vulgaris, foliaceus, and controls (P= 0.041), foliaceus group more positive staining than vulgaris group and both more than controls, but not for HSV2, EBV, and HHV8 markers. Positive staining for HHV8 occurred in 30% of PF patients and 15% of PV patientsbut P value was not significant (0.171).Conclusion: Like previous studies, our research also indicated significant prevalence of HSV1 in lesions of pemphigus patients, especially in pemphigus foliaceus. We collected new cases ofpemphigus before starting immunosuppressive therapy, so we think that the presence of HSV1 in skin lesions of patients can act as a triggering factor for the disease which could not be attributed to the suppressive therapy.

Background: Various kinds of sensitizers are administrated foralopecia areata treatment. The aim of this study was to evaluatetreatment response to Dinitrochlorobenzene (DNCB) in alopeciaareata patients.Method: In this study, 117 patients were treated with DNCBunder a specific checklist. All patients were sensitized with a 2%DNCB and then treated with ascending DNCB concentrations(0.001%-2%). Response to treatment was categorized as none,mild, moderate and marked improvement.Result: Thirty three (27.5%) patients showed no response, 49(40.8%) had relapse 6 months after improvement, 29 (24.2%)had no relapse 6 months after the treatment and 6 patientswere excluded because they did not return for follow-up visits.Response to treatment in patients without eyelash and eyebrowinvolvement increased significantly (P=0.01). We did not observeany side effects except for localized dermatitis seen in 5% of thepatients.Conclusion: With respect to the suitable response to DNCBapplication and its availability, the authors suggest that DNCBbe reconsidered in alopecia areata. However, attention must bepaid to its mutagenicity..
