The aims of this study were to determine the prevalence of H. pylori seropositivity in patients with psoriasis, to evaluate the relationship between PASI (Psoriasis Area and Severity Index) scores and H. pylori infection, and to assess the impact of H. pylori infection on the response to treatment. A total of 300 patients with psoriasis and 150 non-psoriatic healthy controls were enrolled in the study. Patient PASI scores were recorded and H. pylori stool antigen tests performed in both patients and controls. Fifty patients with H. pylori infections were randomly assigned to one of two groups, one of which received acitretin with H. pylori treatment and the other acitretin alone. Statistical analyses were performed using chi-square and logistic regression tests. PASI scores were significantly higher in patients with H. pylori infections. Treatment aimed at eradicating H. pylori infection enhanced the effectiveness of acitretin therapy and shortened response times. Our results suggest that H. pylori infection plays a role in the severity of psoriasis, and that eradicating such infections enhances the effectiveness of psoriasis treatment.

Insulin resistance in women with hirsutism.

Filiz Cebeci; Nahide Onsun; Meral Mert

Introduction There are still not enough data showing whether patients with idiopathic hirsutism (IH) also have insulin resistance. The association between polycystic ovary syndrome (PCOS) and insulin resistance is well documented in the literature, but the Rotterdam Consensus has concluded that principally obese women with PCOS should be screened for the metabolic syndrome. We intended to investigate the presence/absence of insulin resistance in non-obese women with hirsutism. Material and methods Twenty-eight women with PCOS (14 non-obese and 14 obese), 12 non-obese with IH, and 16 non-obese healthy women were included in the study. The presence of insulin resistance was investigated by using basal insulin levels and the homeostasis model assessment (HOMA) score in the study group. Results Patients with obese and nonobese PCOS had significantly (p < 0.05) higher basal insulin levels and HOMA scores than IH and control subjects. Insulin levels and HOMA scores did not differ between obese and non-obese PCOS patients. Patients with IH did not show any difference from the control group. Conclusions Insulin resistance exists in non-obese women with PCOS as well as obese women with PCOS. The PCOS is associated with insulin resistance independent of obesity. Insulin resistance should be assessed in all hirsute women with PCOS regardless of their body mass index. More studies in larger numbers of patients should be performed to investigate the role of insulin resistance in women with IH.

Abstract Purpose. Psoriasis vulgaris is one of the most common skin disorders. Patients with psoriasis carry an excessive risk of atrial fibrillation (AF). The differences between the maximum (Pmax) and the minimum (Pmin) P-wave duration on ECG are defined as P-wave dispersion (PWD). Prolongation of PWD is an independent risk factor for the development of AF. The aim of this the study was to investigate P-wave duration and PWD in patients with psoriasis. Methods. Sixty-one adult patients with psoriasis vulgaris (group 1) and 58 age and sex-matched healthy individuals (group 2) were included in this study. ECG recordings were obtained, and the P-wave variables were calculated. Results were reported as mean ± standard deviation and percentages. Continuous variables were analysed using Students t test. A value of P < 0.05 was considered statistically significant. Results. Pmax and PWD were significantly higher in group 1 than in group 2 (108.8 ± 21.3 ms versus 93.3 ± 13.0 ms, P < 0.001; 67.4 ± 22.9 ms versus 45.0 ± 19.6 ms, P < 0.001, respectively). Also, Pmin was significantly lower in group 1 (41.3 ± 12.3 ms versus 48.3 ± 14.3 ms, P = 0.04). The psoriasis disease activity score and hsCRP correlated with PWD (P < 0.01). Conclusions. Atrial conduction of sinus impulses was impaired in patients with psoriasis vulgaris. It was more prominent in patients with severe disease. Physicians caring for patients with psoriasis vulgaris should screen them for AF development.

Pemphigus vulgaris (PV) is an autoimmune disease involving the skin and mucous membranes. The frequency of upper airway tract (UAT) and upper gastrointestinal tract (UGIT) involvement in PV is not clearly known. Our aim was to determine the incidence of UAT and UGIT involvement in patients with PV. Thirty-seven patients who were diagnosed with PV and treated between March 2008 and April 2009 at the Dermatology Department of the Vakif Gureba Teaching and Research Hospital were included. All patients were evaluated for UAT manifestations by endoscopic examination, and 22 of 37 patients were investigated for UGIT involvement by gastrointestinal endoscopy. Mucosal biopsies were obtained by UGIT endoscopy for direct immunofluorescence (DIF) examination, and a histopathological examination was conducted in patients with active UGIT mucosal lesions. Thirty-five of 37 patients (94.6%) had active pharyngeal, laryngeal, or nasal PV lesions on endoscopic evaluation. Oral symptoms (83.8%) and active oral PV lesions were the most frequent findings (100%). Pharyngeal lesions (64.9%) were the most commonly present lesions on UAT examination. The frequency for laryngeal and nasal lesions was 51.4% and 21.6%, respectively. Five of 22 patients (22.7%) presented with active laryngeal and esophageal lesions. Twenty-one of 22 (95.4%) patients had positive DIF results. We believe that UAT and UGIT endoscopies are useful and necessary diagnostic methods in patients with PV with or without UAT and UGIT symptoms. UAT and UGIT endoscopies should be performed as standard diagnostic procedures in all patients with PV.

The data on long‐term efficacy, safety and drug survival rates of conventional systemic therapeutics in pediatric psoriasis is lacking. The primary aim of this study is to investigate acitretin, methotrexate, cyclosporin efficacy, safety and drug survival rates in pediatric patients as well as predictors of drug survival. This is a multicenter study including 289 pediatric cases being treated with acitretin, methotrexate and cyclosporin in four academic referral centers. Efficacy, adverse events, reasons for discontinuation, 1, 2‐ and 3‐year drug survival rates, and determinants of drug survival were analyzed. A 75% reduction of Psoriasis Area and Severity Index score or better response rate was obtained in 47.5%, 34.1% and 40% of the patients who were treated with acitretin, methotrexate and cyclosporin, respectively. One‐year drug survival rates for acitretin, methotrexate and cyclosporin were 36.3%, 21.1% and 15.1%, respectively. The most significant determinant of drug survival, which diminished over time, was treatment response whereas arthritis, body mass index and sex had no influence. Although all three medications are effective and relatively safe in children, drug survival rates are low due to safety concerns at this age group. Effective disease control through their rational use can be expected to improve survival rates.

Background Psoriasis vulgaris is one of the most prevalent chronic, inflammatory skin disorders. Patients with psoriasis have excess risk of essential hypertension. Masked hypertension (MH), defined as normal office blood pressure (BP) with elevated ambulatory BP (ABPM), has been drawing attention recently due to its association with increased risk of developing sustained hypertension, cardiovascular morbidity, and mortality. The aim of this study was to investigate the prevalence of MH in psoriatic patients. Material/Methods On hundred and ten middle-aged, normotensive, non-obese patients with psoriasis vulgaris and 110 age- and sex-matched normotensive controls were included in the study. ABPM was performed in all participants over a 24-h period. The clinical severity of the disease was determined according to current indexes. Results The prevalence of MH among subjects with psoriasis vulgaris was 31.8% and increased compared to control subjects (p<0.01). Predictors of MH in patients with psoriasis vulgaris were detected as male sex, smoking, obesity-related anthropometric measures, and disease activity. Male sex, waist circumference, and diffuse psoriatic involvement were detected as independent predictors of MH. Conclusions MH is prevalent in patients with psoriasis vulgaris. Assessment with ABPM and close follow-up for development of hypertension is reasonable.

Localized blastomycosis-like pyoderma with good response to cotrimoxazol and cryotherapy.

Ozlem Su; Cuyan Demirkesen; Nahide Onsun

Blastomycosis‐like pyoderma is an unusual, exaggerated, vegetative‐tissue reaction to a prolonged primary or secondary bacterial infection. It is a rare disease, usually seen in immunocompromized patients. We report a case of localized blastomycosis‐like pyoderma responding poorly to classic treatments, but that gave a dramatic response to a combination treatment of cotrimoxazol and cryotherapy.
