Ege Bölgesinde Organik Zeytin Yetiştiriciliği

Bu çalışmada, insan beslenmesi ve sağlığı açısından çok önemli bir ürün olan zeytinin yetiştirilmesinde, konvansiyonel yöntemlere alternatif olarak organik tarım yöntemlerinin uygulanabilirliğinin belirlenmesi, fenolojik, pomolojik ve ekonomik farklılıkların ortaya konması amaçlanmıştır. Çalışma Güney Ege Bölgesinin en önemli yağlık çeşidi olan Memecik zeytin çeşidinde Zeytincilik Araştırma Enstitüsünün Kemalpaşa üretim alanında 2004-2007 yılları arasında yürütülmüştür. Çalışmada organik parsellerde toprak verimliliğini artırmak amacıyla yeşil gübreleme, organik gübre, organik tarım yönetmeliğinde izin verilen mineral maddeler, konvansiyonel parsellerde ise kimyasal gübreler uygulanmıştır. Zeytin sineği popülasyon takibi Mc phail ve sarı yapışkan tuzaklar, zeytin güvesi ise delta tipi feremon tuzaklar ile yapılmıştır. Organik parsellerde zeytin sineği mücadelesinde Ecotrap, neemazal ve kaolin uygulamaları yapılmıştır. Konvansiyonel parsellerde mücadele Fenthion ile yapılmıştır. Her iki parseldeki ağaçlarda sürgün boyu, somak ve çiçek adeti, meyvelerde ise tane adedi ve ağırlığı, eni, boyu, et/çekirdek oranları, ürün miktarları tespit edilmiştir. Elde edilen zeytinyağlarında ise yağ asitleri bileşimleri ve zeytinyağı kalite parametreleri değerlendirilmiştir. Ayrıca yaprak ve toprak analizleri ile bitki besin maddelerinin değişimleri incelenmiş, parsellerden elde edilen meyvelerde kalıntı analizleri yapılmıştır. Meyve örneklerinde yapılan analizlerde organik fosforlu nitrojenli ve sülfürlü pestisitlere rastlanmamıştır. Her iki grupta da ürün miktarı, yağ kalite parametreleri ve yağ asitleri bileşiminde önemli bir farklılık bulunmamıştır. Yapılan organik tarım uygulamalarıyla, konvansiyonel yöntemler uygulanarak sağlanan verim ve kalitede ürün elde edilmiştir

Hypothyroidism in Children with Serous Otitis Media

Objective:In this study, we aimed to evaluate the co-existence and prevalence of hypothyroidism in patients with otitis media with effusion (OME) and to determine the possible relationship between OME and hypothyroidism.Methods:The subject group consisted of 46 paediatric patients (26 boys, 20 girls), ranging in age from 4 to 14 years (mean age±SD 7.78±2.86 years), who were treated in the department of otorhinolaryngology for OME; the control group composed of 30 healthy children (20 boys, 10 girls), ranging in age from 3 to 14 years (mean age±SD 7.20±2.86 years). Triiodothyronine (Free T3), thyroxin (free T4), and thyroid-stimulating hormone (TSH) values of 46 children who were treated for OME, in addition to 30 healthy children, were evaluated.Results:Seven patients (15.2%) in the OME group, and one patient (3.3%) in the control group had subclinical hypothyroidism marked only by serum TSH elevations. All of the children in this study, regardless of whether from the subject or control group, had normal serum free T3 and free T4 levels. There was no significant difference between subject and control groups (p>0.05).Conclusion:Although there was no statistically significant difference between subject and control groups in this study, further studies with larger patient groups are needed to investigate the role of hypothyroidism in the aetiology of OME

Clinical Characteristics and Visual Outcomes of Pediatric Optic Neuritis: A Single Center Experience

INTRODUCTION: The aim of this study was to describe the clinical characteristics, visual outcomes of pediatric patients presenting with first-episode of optic neuritis. METHODS: We reviewed medical records of the patients newly diagnosed with optic neuritis younger than 18 years between January 2014 and December 2018 retrospectively. RESULTS: Twenty-eight patients were included to this study. The mean age at first onset of optic neuritis was 13.2+-3.1 years (range 6.2-17.3 years). The mean follow-up period was 4.2+-3.2 (range 0.6-13.08) years. 7 of 28 (25%) patients had recurrent optic neuritis. Optic neuritis involvement was unilateral in 17 of 28 (60%) patients. Forty percent of the patients had idiopathic optic neuritis. Of the six patients with demyelinating lesions in cranial magnetic resonance imaging (MRI) at the first admission, three were diagnosed with multiple sclerosis (MS) at the time of first optic neuritis attack, and three were diagnosed within 13.4+-4.8 months after the first episode. Eight of 21 optic neuritis patients (38%) had oligoclonal band positivity and the incidence of MS was significantly higher in these patients (p=0.014). The mean visual acuity at nadir was 0.48+-0.27 at admission. Whereas it was 0.74+-0.31 and 0.76+-0.33 at 1 and 6 months respectively. There was a strong correlation between first and sixth-month visual acuity (r=0.98, p=0.00). DISCUSSION AND CONCLUSION: Our study demonstrated that poor visual acuity (worse than 0.5) at 1 month can predict poor vision at 6 months. The patients with demyelinating lesions in cranial MRI at their first optic neuritis episode, are more likely to develop MS during the follow-up

Hepatobiliary insufficiency-candidate of transplantation newborns and anesthesia (two cases)

Biliary atresia (BA) is the most common and important neonatal hepatobiliary disorder and is seen in 1 in 8.000 to 1 in 18.000. Consequently, 70-80 % of BA patients will eventually require liver transplantation, approximately half in the first 2 y of life. Early diagnosis and therapy is essential especially for the survival of patients with biliary atresia

SAFRA YOLLARI PATOLOJİLERİNDE ÇOK KESİTLİ BİLGİSAYARLI TOMOGRAFİ VE ENDOSKOPİK KOLANJİOPANKREATOGRAFİ BULGULARININ KARŞILAŞTIRILMASI

OBEZ ÇOCUKLARDA BEYNİN DİFÜZYON AĞIRLIKLI MANYETİK REZONANS GÖRÜNTÜLEME BULGULARI

Aim: To evaluate Diffusion Weighted Magnetic Resonance Imaging (DW MRI) findings in hunger and satiety related centers of the Brain in Obese Children. Material and Methods: 91 participants were enrolled in the study and 41 of them diagnosed as obese, 19 of them as overweight and 31 of them as non-obese volunteers and ages were ranged between 4-16. Diffusion weighted echo-plantar images of these cases taken in b100, b600, b1000 and b2000 gradient values and for each case b values determined for 14 regions of brain which are related with hunger and satiety. These regions are hypothalamus, hippocampal gyrus, middle temporal cortex, insula, corpus striatum, cingulate gyrus, orbitofrontal cortex, thalamus, midbrain, amygdala, occipital cortex, dorsomedial frontal cortex, dorsolateral frontal cortex and cerebellum. Measurements made with b600, b1000 and b2000values on 14 regions determined on Apparent Diffusion Coefficient (ADC) map for each group. Results: In ours study we have found a statistically significant difference between control and obese group,control and overweighed group and overweighed and obese group in ADC values in comparison of b600, b1000 and b2000 (
