Amaç: Yaygın Gelişimsel Bozukluklar (YGB) ve eşlik eden Dikkat Eksikliği Hiperaktivite Bozukluğu (DEHB) belirtileri olan olgularda Metilfenidat (MPH) ilk tedavi seçeneği olmakla birlikte, sadece DEHB olan olgulara göre daha fazla yan etkiye yol açabildiği ve klinik yanıtın çok değişken olabileceği bilinmektedir. Bu çalışmanın amacı YGB ve Hafif Düzey Mental Retardasyonu (MR) olan olguların MPH'a yanıtı- nın yalnızca DEHB olan olgularla karşılaştırılması ve CES-1 gen polimorfizmleriyle ilişkisinin bulunup bulunmadığının belirlenmesidir. Yöntem: YGB ve eşlik eden DEHB varlığında tükürük örneği alınarak MPH'ı metabolize eden enzim olan Karboksilesteraz-1 (CES-1) polimorfizmleri (Arg199/His, Ser75/Asn ve Ile49/Val) incelenmiş olup MPH yanıtı Dikkat Eksikliği ve Yıkıcı Davranış Bozuklukları için DSM-IV'e Dayalı Tarama ve Değerlendirme Ölçeği ve Klinik Global İzlem Ölçeği ile değerlendirilmiştir. Bulgular: YGB ve eşlik eden DEHB varlığında olguların, DEHB, DEHB ve eşlik eden Hafif Düzey Zeka Geriliği olan olgulara göre daha kötü MPH yanıtı verdikleri ve CES-1'de Arg199/His polimorfizminin istatistiksel olarak anlamlı oranda yüksek olduğu bulunmuştur. Sonuç: Bu çalışma YGB ve eşlik eden DEHB olan olgularda CES-1 Arg199/His polimorfizminin incelendiği ilk çalışmadır.Objective: Methylphenidate is the first-choice medication for the Pervasive Developmental Disorders (PDDs), and comorbid Attention Deficit Hyperactivity Disorder (ADHD). But this approach generally results with poor outcomes, and increased adverse effects. It is aimed to investigate the comparison of cases who diagnosed with PDDs and Mild Mental Retardation (MR) and cases with pure ADHD in terms of the clinical response to MPH. Also we aimed to investigate the relations between CES-1 polymorphism gene and the clinical response to MPH.Methods: For clarifying this we searched for three polymorphisms (Arg199/His, Ser75/Asn, and Ile49/Val) in carboxylesterase-1 gene (CES-1) in the saliva of patients diagnosed with PDD+ADHD. Also, we assessed the clinical response to MPH by dimensional approach using the Attention Deficit Hyperactivity Disorder Rating Scale IV and Clinical Global Impression-Improvement scale. Results: PDD+ADHD groups had significantly higher Arg199/His polymorphism, and clinically responded poorer with symptoms sometimes even worsening to the MPH treatment compared with "pure" ADHD and ADHD+MR groups. Conclusion: This is the first study that an association between Arg199/His polymorphism in CES1 and altered treatment response to MPH in patients with PDD that presents with symptoms of ADHD

Epidemiology of pemphigus in Turkey: One-year prospective study of 220 cases

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation).  The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.   </p
