Background: Sarcoidosis is a granulomatous multisystem disease of unknown etiology. It has recently been tired to detect Mycobacteria genome in biopsy specimens of patients with sarcoidosis by Polymorphism chain reaction method. Objective: To detect and identify Mycobacteria species in cutaneous lesions of the patients with sarcoidosis by PCR-RFLP. Patients and methods: 20 patients with clinical diagnosis of sarcoidosis were enrolled in this study. Clinical manifestations, appearance of naked granuloma under light microscope and exclusion of other diagnoses confirmed the diagnosis of sarcoidosis in the patients. By PCR-RFLP, genome of Mycobacteria species was searched in paraffin embedded specimen of skin biopsies of the patients. Four PCR positive skin biopsy specimens of patients with cutaneous tuberculosis were used as positive control. 10 skin biopsy specimens with other than tuberculosis were used as negative control. Results: Mycobacteria genome was not detected in any specimens of the patients. Conclusion: Our findings do not support the role of Mycobacteria species in the pathogenesis of sarcoidosis.

Background: Common wart is one of the most prevalent skin diseases, caused by human papilloma virus. Numerous therapeutic modalities have been used in the treatment of warts. Objectives: This study was designed to evaluate and compare the efficacy of 5% 5-fluorouracil (5-FU) ointment with cryotherapy in the treatment of common warts of hands. Patients and Methods: In a single blind, prospective clinical trial, 30 patients with bilateral common warts of hands referred to Dermatology Clinic of Razi Hospital, were recruited. The lesions on one hand of the patients were treated by cryosurgery and on the other hand with 5% 5-FU ointment twice daily for about 12 weeks. Results: After 12 weeks, 93% of patients treated by cryotherapy (The mean treatment period 7.5 weeks), and 66.7% of patients received 5% 5-FU ointment (The mean treatment period 6.9 weeks) were completely cured. No significant side effects were noted in patients who received 5% 5-FU ointment. Conclusion: 5% 5-FU ointment can be used as appropriate, household and inexpensive treatment in the management of common warts.

Background: Localized and extensive clinical subtypes of alopecia areata (AA) including alopecia totalis and alopecia universalis differ in genetic and immunologic aspects. Objective: Comparison of epidemiologic aspects of localized and extensive subtypes of AA. Patients and Methods: In a prospective descriptive study, 180 patients suffering from AA attending the skin clinics of Razi Hospital in Tehran in 6-month period were studied. The epidemiological aspects of the disease including age at onset, duration, family history, and mental stress were compared in the localized and extensive subtypes of AA. Results: The age at onset was 13.2 years in localized and 19.3 years in extensive AA (P<0.05). The duration of disease was remarkably longer in the extensive form (42.5 months vs. 17.5 months in localized AA). The role of mental stress was mentioned in 55.6% of cases with extensive form and 27.8% of cases with localized AA (P<0.05). There was no relation between family history of AA and the clinical subtype of disease. Conclusion: Extensive AA begins at a younger age, has longer course, and stronger relation with stress.

Background: Vitiligo is a common disease. Its etiology is not known, but 30% of patients have a positive family history. Studies have been done on the influence of ABO and Rh blood groups on susceptibility to some diseases. Objective: The purpose of this case-control study was to evaluate the association of ABO and Rh blood groups with vitiligo. Patients and Methods: This study was performed on 200 vitiligo patients referred to skin clinics of Razi Hospital. The blood groups of patients were determined and compared with 200 control subjects and the general blood group distribution in Iran (Published by Iran Blood Transfer Organization). Results: There was no specific association established between vitiligo and ABO and Rh blood groups. Blood group B showed the most difference but still it was not significant (P>0.05). Conclusion: There was no association with the ABO and Rh blood group in vitiligo patients.

Background: Oral ivermectin is recently introduced for the treatment of scabies. Objective: The objective of this clinical trial was to compare the efficacy and safety of oral ivermectin and topical Gamma Benzene Hexachloride (GBH) 1% for the treatment of scabies. Patients and Methods: Fifty-eight cases were randomly assigned in the two treatment groups. In the ivermectin group, patients received a single oral dose of the drug (200 µg/kg). In the case of any signs of active disease, a second dose was administered one week later. All the patients in the GBH group received two topical applications of the drug, one week apart. The patients were seen after 48 hours, 1, 2, and 4 weeks. Results: Of the 37 patients treated with ivermectin, 27 (73%) showed clinical cure with a single dose and 10 (27%) required a second dose one week later. In the 21 patients treated with GBH, 18 (85.7%) received two applications of GBH, and three cases (14.3%) were cured by an additional curse of precipitated sulfur 6%. No serious side effects were seen in either group. The mean time for the drop of pruritus, the sense of well being and the healing of lesions, were each shorter with ivermectin than GBH, and the differences were statistically significant. Conclusion: Although all of the patients treated with ivermectin or topical GBH were cured, ivermectin cured faster than topical treatment.
