Background: Pityriasis rosea (PR) is a common papulosquamousskin disorder that is suspected to have an infectious etiology.We aimed to study the role of human herpesvirus-6 (HHV-6) inthe pathogenesis of PR.Method: We used immunohistochemical (IHC) assays to detectHHV-6 in patients with PR. Fifty-one patients with PR and 35 ageand sex matched healthy control samples were enrolled in thestudy. The intensity and percentage of cell staining for HHV-6infection were evaluated and recorded.Result: The intensity of IHC staining was negative in 25 (49.01%)patients and 24 (68.58%) control samples while it was +1 in 6(11.77%) patients and 11 (31.42%) control samples, +2 in 4 (7.85%)patients and +3 in 16 (31.37%) of them. The incidence of moderateand intense staining for HHV-6 was significantly higher amongpatients with PR than the control group (P value < 0.01).Conclusion: We concluded that HHV-6 infection may play arole in some patients with PR. The rate of HHV-6 infection wassignificantly higher in PR patients than the control group.

Background: The standard patch test is known as the most reliable test to identify and confirm causative agents of allergic contact dermatitis (ACD). Previous studies have shown that the prevalence of specific allergens varies by geographic area. The results of patch test in patients visiting our dermatology clinics with suspected ACD were prospectively investigated and compared with those reported in the literature of Iran.Method: We performed the European Standard Series patch test produced by Almiral Hermal GmbH, containing 28 allergens in a group of 100 patients (55 females and 45 males) with suspected ACD who were referred to Emam Reza and Ghaem Hospitals, Mashhad, in 2010-2011. The tests were read after 2 and 4 days.Result: Fifty-four percent of the patients had 1 or more positive reactions of which 65% were relevant to current or past dermatitis. Positive reactions were due to 12 allergens. The most frequent allergens were nickel sulfate (25%) and potassium

Background: Vitiligo is a common acquired disorder of the skin. The disease is characterized by depigmented macules and patches on the skin. Autoimmunity has a crucial role in the pathogenesis of the vitiligo. Vitiligo is frequently associated with different autoimmune diseases such as thyroid abnormalities and diabetes. This study aimed to evaluate the association between vitiligo and diabetes mellitus.Method: This case-control study was conducted on 70 patients with established vitiligo disorder and 70 non vitiligo individuals as the control group. In the case group, we performed two tests, fasting blood sugar (FBS) and oral glucose oral tolerance test (OGTT), while only FBS was checked in the control group.Result: The results of our study showed that out of 70 people in the case group, 18 (25.71%) had impaired FBS while only 4 (5.7%) had impaired GTT3. Statistical analysis showed p-value=0.015 which indicated a significant difference in impaired FBS between case and control groups. We had half and 1 hour GTT data (GTT1 and GTT2) and all patients with impaired GTT1 (4 individuals) and GTT2 (5 individuals) were females with a significant difference (P-value = 0.021 and 0.017, respectively).Conclusion: Periodical laboratory investigation for diabetes mellitus in vitiligo patients, particularly in females, seems to be necessary.

Introduction: Acne is a common problem in adolescent and youngage groups, for which several risk factors have been suggested.One of the risk factors is smoking. In studies on the relationshipbetween smoking and acne, conflicting results have been obtained.Method: This study was conducted on 133 male patients whowere visited at the dermatology clinic of Imam Reza hospital dueto acne as the case group, and 133 healthy individuals withoutany skin diseases including acne among those accompanying thepatients as the control group. The case and the control groups wereage matched. For each patient who had the criteria for inclusionin the study, a questionnaire was completed and the necessaryinformation was collected and then analyzed statistically.Result: The questionnaires were filled for 133 patients with acneand 133 healthy controls. Twenty-nine patients with acne (21.8%)and 12 patients in the control group (9.1%) were smokers, and thedifference between them was significant (P = 0.004). The numberof cigarettes smoked per day was significantly different in thetwo groups (4.75 in the case group versus 1.88 in the controlgroup). No correlation was found between smoking and acnelocalization, severity of acne, the type of lesion, symptomaticor asymptomatic nature of acne and acne complications. In thecase group, the smokers developed acne at an older age thanthe non-smokers.Conclusion: Patients with acne were more likely to smoke thanpatients without acne; thus, smoking might be a factor affectingthe incidence of acne.

Background: Precancerous lesions are disorders that are highlylikely to become malignant. Early diagnosis of precancerous skinlesions helps to prevent skin cancers. The aim of this study wasclinicopathological assessment of precancerous skin lesions inpatients referred to the dermatology department of Imam Rezahospital.Method: Two hundred and nine patients who were diagnosed withprecancerous lesions and referred to the dermatology departmentof Imam Reza hospital from 1997 to 2007 were studied. Studyparameters included participants’ age, sex and occupation, typeof precancerous skin lesion, clinicopathological type of the lesionand location. The data was collected from the patients’ recordsin the dermatology department and their microscopic slides inthe pathology department.Result: The most common precancerous skin lesion was actinickeratosis (68.4%) followed by Bowen’s disease (7.2%). About67.5% of the patients were male with a mean age of 61.7 years.Moreover, 53.1% of the patients worked outdoors. The mostcommon site of the lesions was head and neck (83.3%) and 18.7%of lesions were associated with malignancy. The most commonpathological form of actinic keratosis was the proliferative type(28.9%).Conclusion: The results of this study showed that precancerousskin lesions were more prevalent in men aged over 50 years, insun-exposed areas and in occupations practiced outdoors. Inaddition to squamous cell carcinoma, these lesions could alsobe associated with basal cell carcinoma.

Background: Surgical treatments of vitiligo are punch grafting, blister grafting, flip-top transplantation, split skin grafting, etc aiming at rebuilding of melanocytic population in those patients who do not respond to medical treatment . The objective of this study was determination of efficacy of blister grafting technique in the treatment of vitiligo. Methods: This study was done on 10 patients with vitiligo of face and /or distal extremities who had received different medical treatments including PUVA and had not responded, and their diseases were stable. Blister in recipient site was created by cryotherapy and in donor site by using vacuum device. Then donor site blister was transferred to the recipient site and both sites were covered by dressing. Results: 10 patients (8 females & 2 males) with mean age of 31.2±11.4 years entered the study. After 1-6 weeks, first signs of repigmentation were observed and after 4 months complete repigmentation occured in 7 patients (70%) In two patients, a repigmentation of more than 50% was observed while in one patient no pigmentation was seen which was related to errors in surgical technique. Conclusion: Blister grafting surgery in limited patches of vitiligo which have not responded to medical treatments gives excellent results of prolonged repigmentation without any scar formation.

Background: It appears that chronic lupoid leishmaniasis is the result of type 2 predominant T helper response to parasite and a defect in the down regulation of IL-4 production during infection. The objective of this study was to evaluate the underlying immune status in these patients and their predominant T helper activity we considered serum IgE as an indicator of TH2 activity and IL-4 production as it has been shown in atopic diathesis.Methods: In 34 cases of chronic lupoid leishmaniasis serum IgE level was measured and compared with 34 control cases of age and sex matched healthy individuals without atopic diathesis. P< 0.05 was considered statistically significant.Results: There were 21 females and 13 males with a mean age of 14.35±8.3 years in the patients group. The mean age of the control group was 16.11±8.4 (P>0.05 and matched). Nine patients had atopic diathesis. Mean serum IgE level in patients and in the control group was 102.6±22.4 i.u/ml and 135.6±24.9 i.u/ml, respectively (P>0.05 with no significant difference). Mean serum IgE level in patients without atopic diathesis (25 cases) was 66.8±11.3i.u/ml which was significantly lower than the control group (P<0.05).Conclusion: In this study, serum IgE level in cases with chronic lupoid leishmaniasis was lower than the control group and it seems that in these patients, there is not an underlying Th2 over activity as it is seen in atopic diathesis.

Introduction: Genital infections with human papilloma virus (HPV) are the most common sexually transmitted disease in the United States. Several predisposing factors are known for this infection. So far, no studies on the risk factors and clinico-epidemiologic aspects of genital warts in Iran have been reported. So, we performed this study to evaluate epidemiologic aspects of anogenital warts in Mashhad, Iran. Methods: In this case-control study, 100 patients with genital warts who referred to the dermatology clinic of Imam-Reza hospital (August 2005 - August 2007) and 100 age, sex and marital status matched healthy controls were included. Clinical and epidemiologic data were recorded using designed questionnaire. Finally, chi-square and t-student tests were used for statistical analysis. Results: Male to female ratio was 0.87. The majority of the patients aged 30-39 years. Glans of the penis and posterior fourchette were the most common sites of involvement. Positive history of sexual contacts and sexual transmitted diseases (STDs), use of condom, pregnancy, addiction, use of swimming pools and number of marriages were significantly different in two groups. Conclusion: Younger age, higher number of marriages, having several partners, non-traditional sexual behavior, pregnancy, use of swimming pools, refuse to use condoms, history of other STDs, immune suppression, use of immunosuppressive drugs and topical steroids were the main risk factors of anogenital warts in this study.

Background and aim: Psoriasis is a dermatologic disease which not only involves the patient physically, but also affects patient's quality of life. Due to its life time duration and psychologic burden, we decided to evaluate patient's quality of life using psoriasis disability index (PDI). Materials and methods: From August 2006 till March 2007, 80 patients referring to Imam-Reza dermatology clinic completed the PDI questionnaire and a demographic questionnaire. Collected data were analyzed by t-test, one way ANOVA tests using SPSS software. Results: 46.2% of patients were male and 53.8% female. The mean age of patients was 40.2 years. 10% had positive family history of psoriasis. 47.5% had a history of hospitalization. 41.3% had articular and 53.8% had nail involvement. Mean morbidity duration was 12.6 years and mean PDI score was 17.4±10 (maximum and minimum scores: 37 and 1 respectively). There was significant difference in mean PDI score in groups considering age, sex, education, location, duration and extent of disease, hospitalization history, nail involvement and type of treatment. Most disability was seen in the treatment field (both sexes) and occupation /school (men) and least disability was seen in individual relationships.Discussion: Psoriasis can reduce the patient's quality of life and satisfaction severely. Therefore supportive strategies can improve their quality of life.

Background and aim: Deficiency of zinc -as a necessary trace element-causes exacerbation of acne and development of acne lesions. Also zinc has been used in acne treatment. In this study serum zinc level was evaluated in severe acne cases. Materials and methods: Severe acne cases as well as sex and age matched controls were selected from dermatology clinics of Imam Reza and Qaem Hospitals during 2003 to 2005. Five ml of blood was sampled from each individual and serum zinc level was measured by atomic absorption spectrophotometric method. The mean of zinc serum level between the two selected groups was compared by t and Mann-Whitney tests. Results: Thirty patients (16 females and 14 males) with mean age of 19.8±2.05 years and 28 cases in control group (13 females and 15 males) with mean age of 20.78±2.46 years were included in this study. The mean serum zinc level in patients and control groups were 99.85±18.07 and 101.57±10.52µg/dl, respectively. There was no significant difference between the serum zinc level of the two groups.Conclusion: In this study, there was no relation between the serum zinc level and severe acne disease. Considering the high prevalence of acne and the rarity of zinc deficiency in the general population, the etiologic role of zinc deficiency in acne needs a study in a very large sample, or evaluation of acne prevalence in zinc deficient patients.

Background and aim: Basal cell carcinoma (BCC) is the most common skin cancer in white-skin populations. Recent studies suggest that BCC is not a single entity and different histological subtypes show different clinical behavior and might have different etiology. The aim of this study was to assess differences in age, sex, site of distribution and proliferative activity in histological subtypes of BCC. In addition association of BCC with solar keratoses is assessed.Materials and methods: We studied 299 cases of BCC from the archives of department of pathology, Mashad University of Medical Sciences in a three-year period. Clinical data were recorded and histological slides were rewiewed to confirm the diagnosis and histological subtypes. Results: We recorded 345 BCC in 299 patients with mean age of 59.2 years. 70.8% of patients were male and 29.2% were female. Ninety-four percent of lesions were located in head and neck. Solid pattern of BCC was the most frequent subtype. In superficial and micronodular subtypes, patients were younger and the oldest patients had basosquamous BCC. Adenoid BCC had the most mitotic activity. In 22.2% of cases association with solar keratoses were observed.Conclusion: This study showed difference in age, sex, site of tumor, and proliferative activity in various histological subtypes of BCC that might represent different etiologic factors in different subtypes.
