RESUMO
It is known that omalizumab (OMA) is an effective and safe treatment option in the treatment of chronic spontaneous urticaria (CSU). In the literature, there are vary studies about effect of OMA treatment in CSU such as different response rates to treatment, different dose / time regime and different relapse rates after treatment. To investigate the evaluate the effect of at least 1 year continuous OMA treatment on relapse in CSU patients. Fifty patients were included in this study. There was a significant decreased between UAS7 score before and after OMA treatment. There was no significant difference between the sixth and 12th month after OMA for UAS 7 scores. At the end of 12 month,84% of patients had complete or good response to OMA treatment. Twenty-three of 34 patients (67.6%) who discontinued treatment had relapse and 11 patients had no relapse. Duration of disease was significantly higher in patients who had relapse. Based on our study result we suggest that long disease duration may increase the risk of relapse. Although it is not statistically significant, without interruption OMA treatment for more than 1 year may decrease relapse risk in patients who respond well to the therapy.

INTRODUCTION: Mycosis fungoides (MF) is the most common type of primary cutaneous T-cell lymphoma. Prognostic factors may help to evaluate the course of the disease and may also be useful in selecting appropriate treatment plans for patients. AIM: To investigate the potential prognostic factors of MF and their correlations with MF stage. MATERIAL AND METHODS: We evaluated the records of patients with MF who were followed in our lymphoma clinic between 1998 and 2015. Age, sex, disease stage, peripheral blood eosinophilia, eosinophil cationic protein, serum total IgE, lactate dehydrogenase (LDH), and ß2-microglobulin levels were investigated and recorded at the time of diagnosis. RESULTS: There was a statistically significant positive correlation between high ß2-microglobulin levels and the advanced stage of disease (p < 0.001). The older group of patients had statistically significantly higher levels of ß2-microglobulin compared to the younger group (p = 0.001). We found strong, significantly positive correlations between disease stage and ß2-microglobulin, LDH, and total IgE levels (p < 0.001, rho = 0.335; p = 0.001, r = 0.302; p = 0.001, r = 0.311, respectively). Additionally, there were significantly positive correlations between LDH levels and ß2-microglobulin, total IgE levels (p < 0.001, rho = 0.484; p = 0.001, r = 0.212, respectively). Study limitations: A limited number of patients and the retrospective nature of the study. CONCLUSIONS: We found that ß2-microglobulin was a significant prognostic factor in our study population of MF patients. Also, elevated LDH, ß2-microglobulin, and total IgE levels were correlated with advanced disease. Thus, these parameters can be used together to identify patients who have progressed to the later stages of the disease and who require more aggressive treatment.
RESUMO
BACKGROUND/OBJECTIVES: Spitz nevi are melanocytic lesions with clinical, dermoscopic, and histopathologic presentations that may resemble those of melanoma. The evolution of Spitz nevi is a well-known feature. The objectives of this study were to investigate the clinical and dermoscopic features of Spitz nevi and define their evolution. METHODS: A retrospective observational study was performed and 70 Spitz nevi were analyzed using clinical and dermoscopic examination. RESULTS: Seventy patients were included in the study. The most common dermoscopic pattern was globular (n = 35 [50%]) followed by starburst (n = 24 [34.3%]), reticular (n = 8 [11.4%]), and homogeneous (n = 3 [4.3%]). Follow-up data were available for 27 of 70 patients. Of these, 21 demonstrated evolution on the follow-up images. A stable pattern (no evolution) was noted in 6 of 27 lesions. The patients who exhibited evolution were younger on average than the stable group (p = 0.04). CONCLUSION: Based on our study, the most common biologic behavior for Spitz nevi is evolution. Although no significant differences were observed in other clinical features, the inverse relationship between evolution and age is important to consider when attempting to differentiate Spitz nevus from melanoma.

INTRODUCTION: Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disorder. Vitamin D is a liposoluble vitamin synthesized mainly in the skin. Vitamin D has several effects on the skin. AIM: To assess the serum level of vitamin D in children with AD and determine its relation to AD severity. MATERIAL AND METHODS: Sixty patients with AD were enrolled in the study. We evaluated disease severity using the SCORing Atopic Dermatitis (SCORAD) index. The control group consisted of 37 healthy subjects. RESULTS: The mean serum concentration of 25(OH)D3 in patients with AD was not statistically different from control subjects (p = 0.065). The vitamin D level was significantly lower in moderate and severe AD compared with mild AD, and this difference was statistically significant (p = 0.001 and p = 0.004). Vitamin D showed a negative correlation with serum total IgE levels (p = 0.007). There was no significant correlation between total IgE levels and SCORAD scores (p = 0.089). CONCLUSIONS: This study suggests that a low serum vitamin D level is inversely associated with severity of AD in children. Vitamin D has not been included in the routine treatment of AD because of the conflicting results of various studies. Thus, there is a need for more detailed and prospective studies.
RESUMO
Melkersson-Rosenthal syndrome (MRS) is a rare disease characterized by a triad of relapsing or persistent orofacial edema, recurrent lower motor neuron facial nerve palsy and fissured tongue. Acute, painless, non-erythematosus orofacial edema is observed in all patients. We report a case of a 13-year-old girl who presented with a 2-year history of swelling of the upper lip, facial paralysis, and fissured tongue; she was treated successfully with dapsone.

INTRODUCTION: Psoriasis is a chronic, immune-mediated inflammatory disease predominantly affecting the skin, with a complex aetiology. Recently it has been suggested that the chronic inflammation of psoriasis may cause metabolic and vascular disorders. The relationship between obesity and psoriatic arthritis (PsA) is not clear, and there are insufficient prospective studies addressing this subject. AIM: To investigate the relationship between psoriatic arthritis, severity of psoriasis and obesity in the Turkish population. MATERIAL AND METHODS: Patient data from psoriasis outpatient clinics from February 2007 to July 2013 were reviewed retrospectively using the Psoriasis-Turkey (PSR-TR) registration system. Patients' age, onset age, body mass index (BMI), waist circumference, psoriasis area and severity index (PASI), and arthritis information were reviewed. In the outpatient clinics, patients who had joint pain consulted rheumatology clinics. The CASPAR criteria were used for the diagnosis of arthritis. RESULTS: A total of 443 males and 495 females enrolled in this study. The mean age of females was 43.9 years (18-93 years) and the mean age of males was 44.6 years (18-89 years). A total of 231 (25%) patients had psoriatic arthritis. Investigation of the relationship between PASI, BMI, waist circumference (WC) and arthritis revealed a statistically significant relationship between each variable. CONCLUSIONS: In this study we observed a relationship between PsA and high BMI, high WC and high PASI. Psoriatic arthritis is a chronic inflammatory disorder and a chronic inflammatory state induced by adiposity may lead to PsA.
RESUMO
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.

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.

CD4+/CD56+ hematodermic neoplasm (blastic plasmacytoid dendritic cell neoplasm) involving the skin is relatively rare and has been of significant interest in the recent literature. We report here a 64-year-old male who presented with multiple purple-red nodules and plaques on his face, back, and chest. Histological examination of skin biopsies showed an intense hematolymphoid infiltration in the dermis and in the subcutaneous tissue. Stains were positive for CD4 (weak), CD56, and terminal deoxynucleotidyl transferase (TdT). These cells were negative for CD2, CD3, CD5, CD10, CD20, CD30, CD68, and T cell intracellular antigen (TIA). In situ hybridization (ISH) for Epstein-Barr virus was negative and the diagnosis was blastic NK cell lymphoma. The patient was treated with a hyper-CVAD regimen (cyclophosphamide, vincristine, doxorubicine, dexamethasone, methotrexate, and cytarabine).This treatment regimen achieved partial remission but the patient died eight months after the diagnosis. The patient presented with exclusively cutaneous involvement at the beginning but progressed rapidly and died shortly after despite aggressive chemotherapy. Due to its rarity, we present here a case of CD4+/CD56+ hematodermic neoplasm.

Telaprevir is a specific inhibitor of the hepatitis C (HCV) serine protease 3. Cutaneous side effects have been reported with telaprevir. Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare yet severe adverse drug-induced reaction characterized by exfoliative dermatitis and maculopapular rash, lymphadenopathy, fever, eosinophilia, leukocytosis, and myriad internal organ involvement. We report a case of DRESS due to telaprevir. A 64-year-old Caucasian man with chronic hepatitis C developed a progressive diffuse, painful maculopapular exanthema with fever, facial edema, lymphadenopathy at week 11 of chronic hepatitis C therapy with telaprevir, Peg-Interferon alfa-2a, and ribavirin. He had no exposures to any other medications. He presented an eosinophilia (up to 6.29 X 109 cells/L), skin biopsy was consistent with a drug reaction. The HCV treatment was stopped and methylprednisolone 0.75 mg/kg/day was started. Cutaneous and systemic symptoms had a rapid resolution in few days. Telaprevir can activate severe skin reactions that can mimic an infectious disease, therefore early diagnosis and discontinuation of chronic hepatitis C treatment is mandatory.

BACKGROUND: Onychomycosis is a chronic nail infection caused by dermatophytes, Candida, nondermatophyte molds, and Trichosporon. The purpose of this study was to identify the underlying pathogen in patients with onychomycosis in our region. METHODS: A retrospective analysis of 225 cases with onychomycosis, diagnosed over a 27-month period at the Department of Dermatoveneorology, Bezmialem Vakif University, Istanbul, Turkey, and confirmed with culture, was performed. RESULTS: Patient age ranged from 2 to 87 years (mean ± SD, 41.59 ± 17.61), and female patients were more commonly affected (120 cases, 53.3%) than male patients. Lateral and distal subungual onychomycosis was detected in 180 cases (80%). Etiologic agents were as follows: Trichophyton rubrum, 77 cases (34.2%); Trichophyton mentagrophytes, 30 cases (13.3%), Candida albicans, 28 cases (12.4%); Candida parapsilosis, 25 cases (11.1%); Acremonium species, one case (0.4%); Aspergillus species, two cases (0.9%); Fusarium species, four cases (1.3%); and Trichosporon species, three cases (1.3%). CONCLUSIONS: The most frequent isolated etiologic agents were T rubrum for toenails and C albicans for fingernails.

BACKGROUND: Psoriasis is a chronic immune-mediated disease and treatment of psoriasis includes conventional immunosuppressive agents and biological agents. There are a few data on the relationship between psoriasis and melanocytic lesions. Either benign or malignant proliferations may be seen with immunosuppressive treatment. Eruptive nevi and malignant melanoma (MM) have been reported also associated with biological agents There is raising link biological treatment and malignancies. The objective of this paper is to examine the effects of biological agents versus conventional drugs on melanocytic nevi count and dermoscopical features. METHODS: Sixty-seven patients receiving TNF-α antagonists (etanercept, infliximab and adalimumab) and 62 patients receiving methotrexate and cyclosporin included to the trial. Duration of treatment with biological agents ranged from 6 months to 4 years, and between 6 months to 3 years for conventional drugs. Total and regional nevi count and structurel changes of biological treatment was evaluated. All melanocytic lesions checked for dermoscopic features by using Dermogenius Ultra (Linos Photonics GmbH & Co, Munich, Germany). Diagnosis of atypical nevi and doubtful lesions for melanoma was made by using ABCD clinically and, by three point check list (asymmetry, atypical pigment network and blue whitish structures) dermoscopically. RESULTS: There were no significant changes in number of total and regional nevi count and in the dermoscopic features of nevi between biological and conventional treatment groups. We observed dermoscopical changes in only one nevus of a patient receiving etanercept. Histopathological examination of this nevi confirmed the diagnosis of dysplastic nevi. There were no MM and non-melanoma skin cancers in both groups. CONCLUSIONS: We did not observe significant changes in biological and conventional treatment groups there is a need for further studies to determine long-term effects of biological agents on the melanocytic lesions in patients with psoriasis.

BACKGROUND: Congenital melanocytic nevi (CMN) are present at birth. It is well known that the presence of large-sized congenital nevus in early life could predict a major risk of developing melanoma. OBJECTIVE: To investigate the clinical and dermoscopic features of the CMN, to search for and highlight any differences between small-sized, medium-sized, large-sized CMN. METHODS: A nonrandomized observational study was performed. A total of 108 melanocytic nevi were analysed by clinical and dermoscopic examination. RESULTS: Of the subjects, 57.4% were aged less than 16 years, 42.6% were aged 16 and more. Of the nevi, 26 had reticular pattern (24.1%), 35 had globular pattern (32.4%), 13 had reticular-globular pattern (12.0%), 16 had homogeneous pattern (14.8%), 6 had reticular-homogeneous pattern (5.6%), 2 had globular-homogeneous pattern (1.9%), 7 had cobblestone pattern (6.5%), 3 had reticular patchy pattern (2.8%). Atypical dots and globules, focal hypopigmentation and perifollicular hypopigmentation are the most common dermoscopic features of CMN. The rarest dermoscopic feature is the blue-whitish veil. CONCLUSION: Most of the dermoscopic features related with dysplastic nevi up to the present, such as atypical dots and globules, focal hypopigmentation, perifollicular hypopigmentation were observed in CMN, in our study. Congenital nevus and dysplastic nevi may share the same dermoscopic features, therefore it is important to know it is found at birth or not.
RESUMO
BACKGROUND: The role of inflammation has been established in cancer biology and the neutrophil to lymphocyte ratio postulated as a marker of systemic inflammatory response. The prognostic significance of neutrophil to lymphocyte ratio has never been explored in patients with mycosis fungoides. METHODS: Data from 119 mycosis fungoides (MF) patients, diagnosed between 1998 and 2015 at a single centre, were evaluated retrospectively. The prognostic influence of the neutrophil to lymphocyte ratio and other clinico-pathological factors including age, lactate dehydrogenase, stage of disease, beta-2-microglobulin levels, and total IgE levels were evaluated. RESULTS: The mean value of absolute neutrophil count and absolute lymphocyte count (ANC/ALC) ratio was 2.07±1.17 in the patient group, whereas it was 1.76±0.53 in the control group (P<0.05). An ANC/ALC value of 2.85 corresponded to the maximum combined sensitivity and specificity on the ROC curve. ANC/ALC ratios of 2.85 or higher at diagnosis were positively correlated with elevated Beta-2-microglobulin (P=0.026), advanced disease stage, and disease progression (P=0.026, r=0.204) (P=0 .006, r=0.251) (P=0 .018, r=0.216). CONCLUSION: In the present study, we showed that a high ANC/ALC ratio at diagnosis of MF represents a simple, poor prognostic factor for identifying high-risk patients with MF.

BACKGROUND: Vasculitis represents a specific pattern of inflammation of the blood vessel wall that can occur in any organ system of the body. The neutrophil to lymphocyte ratio (NLR) and red blood cell distribution width (RDW) are currently used as markers of inflammation in several diseases. OBJECTIVES: This study analyzed C-reactive protein level (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC), NLR, and RDW in patients who had cutaneous vasculitis, or cutaneous vasculitis with systemic involvement, and in healthy controls. METHODS: A total of 85 individuals were included in our study: 45 with vasculitis and 40 healthy controls. Patients who had complete blood count (CBC) analysis, CRP, and ESR at the time of skin biopsy were included in the study. NLR was calculated from these parameters. RESULTS: NLR, CRP, ESR, and WBC were significantly higher in patients with vasculitis than in healthy controls (p≤0.05), but RDW did not significantly differ between the two groups. CONCLUSIONS: This study suggests that blood NLR may be used for predicting vasculitis, especially cutaneous vasculitis with systemic involvement.

BACKGROUND:: Pruritus is the most commonly occurring subjective symptom of dermatological disease. Published data on both prevalence and intensity of pruritus in psoriasis is limited. OBJECTIVE:: In this study we aimed to investigate the prevalence of pruritus and its relation with psoriasis area severity index, body mass index and presence of systemic disease in patients with psoriasis. METHODS:: We analyzed data of psoriatic patients diagnosed in our psoriasis outpatient clinic between March 2013 and June 2014 collected retrospectively from PSR-TR registration system. RESULTS:: In total, 880 patients were analyzed. Pruritus was more prominent in female patients. This difference was statistically significant. No significant associations were found between age of patients, clinical type of disease and pruritus. The itching was more common in patients with higher body mass index. Presence of pruritus was correlated significantly with severity of psoriasis. Five hundred and sixty of 880 patients had no systemic disease. The presence of pruritus was not related with presence of systemic disease. Existence of systemic disease with psoriasis has minimal effect on pruritus. STUDY LIMITATIONS:: We did not evaluate intensity of pruritus. CONCLUSIONS:: Pruritus is not mentioned within the classical symptoms of psoriasis. Pruritus in psoriasis is a very unpleasant symptom with great potential to impair patient's quality of life and may exacerbate psoriasis as a Koebner phenomenon.

BACKGROUND: Localized scleroderma is a chronic inflammatory skin disease characterized by sclerosis of the dermis and subcutaneous tissue. Platelets play an important role in inflammation. Following activation, platelets rapidly release numerous mediators and cytokines, which contribute to inflammation. OBJECTIVES: To evaluate whether there was any relation between localized scleroderma and platelet parameters. METHODS: Forty-one patients with localized scleroderma were enrolled in the study. The control group consisted of 30 healthy subjects. RESULTS: The mean platelet volume level in the patient group was 9.9 ± 1.3 fl and in the control group was 7.6 ± 1.1 fl. This difference was statistically significant (p< 0.001). The plateletcrit values are minimally higher in the patient group as compared to the control group. It was statistically significant (p<0.001). There was no significant difference in the platelet counts between the two groups (p= 0.560) In the patient group, there was no significant relation between the mean platelet volume levels and clinical signs of disease (p=0.09). However, plateletcrit values are higher in generalized than localized forms of disease (p=0.01). STUDY LIMITATIONS: The limited number of patients and the retrospective nature of the study were our limitations. CONCLUSIONS: This study suggests that platelets might play a role in the pathogenesis of scleroderma. Platelet parameters may be used as markers for evaluating disease severity and inflammatory processes. Thus, there is a need for more detailed and prospective studies.
