Öğe Boosting Tree as a Stronger Approach in Classification: An Application of Carpal Tunnel Syndrome(2012) Ankaralı, Handan; Taşdelen, Bahar; Temel, Gülhan Orekici; Özge, AynurAmaç: Boosting ağaç yöntemi topluluk birleştirme yöntemlerinden en başarılı olanıdır. Birleştirme algoritmalarının temel amacı, zayıf sınıflayıcıların kombinasyonundan tahmin hatası düşük güçlü sınıflayıcılar oluşturmaktır. Gereç ve Yöntemler: Bu çalışmada Karpal Tunel Sendromu vakaları boosting metodunu kullanılarak sınıflanmıştır. Mersin Üniversitesi Tıp Fakültesi Nöroloji Anabilim Dalının Elektrofizyoloji Laboratuvarına 2006-2010 tarihleri arasında Karpal Tünel Sendromu (KTS) ön tanısı ile başvuru yapan bireyler çalışmaya alınmıştır. Boosting Tree uygulaması Statistica 7.0 paket programında yapılmıştır. Bulgular: Test verisi kullanıldığında ise modelin genel doğru sınıflama başarısı %87.67 olarak hesaplanmıştır. Test verisi kullanıldığında son modelin sensitivite ve spesifitesi ise sırasıyla %85.65 ve %92.36 olarak hesaplanmıştır. Sonuç: Kullanılan modelin KTS tanısının konulmasında başarılı bir yöntem olarak kullanılabilir.Öğe Burden of Chronic Migraine in Tertiary Headache Outpatient Clinics: Experience of 10 years a Multicenter Study(Sage Publications Ltd, 2017) Yalın, Osman Özgür; Uludüz, Derya; Sungur, Mehmet Ali; Özge, Aynur…Öğe Identification of Allodynic Migraine Patients with the Turkish Version of the Allodynia Symptom Checklist: Reliability and Consistency Study(Aves, 2017) Özgür, Osman; Uludüz, Derya; Sungur, Mehmet Ali; Sart, Hande; Özge, AynurIntroduction: Cutaneous allodynia is regarded as an expression of central sensitization in migraine. Although the gold standard is quantitative sensory testing, several practical assessment questionnaires have been developed to assess allodynia in migraine. We aimed to establish the first valid Turkish allodynia assessment questionnaire based on a 12-item allodynia symptom checklist and to evaluate the associated factors. Methods: The first part of the study included the translation and cultural adaptation of a Turkish version of the checklist. The Turkish version of the questionnaire was administered to 344 episodic and chronic migraine patients, who were chosen according to the International Classification of Headache Disorders -III beta criteria. Results: The total checklist score showed excellent test-retest reliability (r= 0.821). The internal consistency of the checklist was assessed using Cronbach alpha values and was found to be acceptable (Cronbach alpha for the checklist= 0.767). Data analysis revealed that 10 items of the questionnaire adequately identified allodynic subjects. Cutaneous allodynia was present in 218 (63.4%) migraine patients. Allodynia was more prominent in patients experiencing migraine with aura (p= 0.008) and in females (p< 0.001). Multiple logistic regression analysis found that female gender, aura existence, longer headache duration, and higher attack frequency were the major determinants of cutaneous allodynia. Conclusion: Allodynia is common and has clinical significance in migraine; therefore, establishing a validated Turkish questionnaire for the assessment of allodynia was necessary. In this study, a Turkish version of the allodynia symptom checklist was validated and found to be convenient for the identification of allodynia in migraine patients.Öğe One-year incidence of Chronic Migraine in Tertiary Headache Outpatient Clinics: A multi-center study(Springeropen, 2018) Özge, Aynur; Uludüz, Derya; Yalın, Osman Özgür; Demirci, Seden; Selekler, Macit; Akyol, Ali; Siva, Aksel…Öğe Phenotypic features of chronic migraine(Bmc, 2016) Yalın, Osman Özgür; Uludüz, Derya; Özge, Aynur; Sungur, Mehmet Ali; Selekler, Macit; Siva, AkselBackground: Chronic migraine is a disabling, under-recognized, and undertreated disorder that increases health burdens. The aim of this study was to evaluate phenotypic features and the relevance of accompanying symptoms of migraine attacks in chronic migraine. Method: This study was conducted as part of an ongoing Turkish Headache Database Study investigating the clinical characteristics and outcomes of headache syndromes in the Turkish population. The electronic database was examined retrospectively, and 835 patients with chronic migraine were included. Results: Patient group consisted of 710 women and 125 men (85 and 15 %, respectively). Mean patient age was 36.8 +/- 13.5 years, median value of migraine onset was 60 months (18-120), median headache frequency was 25 days per month (16-30), median of attack duration was 12 h (4-24), and median of intensity was eight (7-9). Increasing headache days per month were inversely related with the presence of nausea, vomiting, phonophobia, and photophobia. Longer duration of headache (months) and higher visual analog scale (VAS) for headache intensity were associated with all accompanying symptoms. Phonophobia, nausea, photophobia, and vomiting were the most frequent accompanying symptoms (experienced by 80.2, 77.6, 71.2, and 40.9 % of patients, respectively). Osmophobia was also frequent in chronic migraine patients (53.4 %) and was closely associated with other accompanying symptoms. Vertigo and dizziness were observed less frequently, and they were not associated with accompanying symptoms. Conclusion: Phenotype of chronic migraine may be associated with the course of chronification. Duration of illness and attack intensity were closely related with the presence of accompanying symptoms, although headache frequency was found to be inversely related to the presence of accompanying symptoms. Osmophobia was also a frequent symptom and was closely related with other accompanied symptoms, unlike vertigo and dizziness. Inclusion of osmophobia into the diagnostic criteria might improve accurate diagnosis of chronic migraine.Öğe The relevance of associated symptoms of migraine according to migraine subtypes: A Clinical study(Springeropen, 2018) Özge, Aynur; Yalın, Osman Özgür; Uludüz, Derya; Mercan, Özlem; Sungur, Mehmet Ali; Siva, Aksel…
