From nomadism to sedentary life in Central Anatolia : the case of Rışvan tribe (1830-1932)

Ankara : The Department of History, İhsan Doğramacı Bilkent University, 2011.Thesis (Master's) -- Bilkent University, 2011.Includes bibliographical references leaves 99-105.This thesis presents an overview of how the Ottoman Empire established its relations with nomads and how it managed to administrate the settlement of nomadic tribes. The aim of this thesis is to analyze the dynamics that made the sedentarization of nomadic tribes necessary in the 19th century with particular reference to the settlement of RıĢvan tribe in Central Anatolia, more specifically in Haymana. In this respect, the effects of this settlement on the population structure and settlement geography of Haymana are examined. The thesis also deals with the challenges the newly settled nomadic RıĢvan tribesmen faced such as the settlement and adaptation problems in the sedentarization process and afterwards. Lastly, the factors that affected and extended the sedentarization process are analyzed in comparison with the experiences in the other Middle-Eastern examples of sedentarization and settlement processesDede, SuatM.S

Meckel Gruber Syndrome diagnosed in two consecutive pregnancies

Meckel Gruber syndrome is a lethal, autosomal recessive, multisystemic disorder that is associated with a mutation affecting ciliogenesis. In this report, we present two consecutive pregnancies of a woman complicated with MKS. In the first pregnancy with MKS, the amniotic fluid index was under 1 cm with bilateral polycystic fetal kidneys. Post-abortion macroscopic examination of the first fetus revealed multiple congenital anomalies including occipital encephalocele, axial polydactyly and pes equinovarus. Ultrasound examination during the second gestation revealed a singleton pregnancy complicated by MKS. There were multiple congenital anomalies including an occipital encephalocele, polycystic and horseshoe shaped kidneys, axial polydactyly, cleft lip and palate

Severe ovarian hyperstimulation syndrome in spontaneous pregnancy treated successfully with cabergoline

Ovarian hyperstimulation syndrome (OHSS) is a relatively common complication in infertile patients treated with exogenous gonadotropins. Ovarian hyperstimulation in spontaneous pregnancies is a rare but possible. The pathogenesis of spontaneous OHSS is not well known. Risk factors for OHSS are young age, polycystic ovaries, low body mass index, high gonadotropin dose, increased estradiol and human chorionic gonadotropin levels, multiple pregnancy, OHSS history, molar pregnancy and hypothyroidism. In this report we present a case of severe spontaneous OHSS with a brief summary of the literature. She was hospitalized and treated in the clinic with the diagnosis of severe OHSS accompanying spontaneous pregnancy

Prenatal diagnosis of fetal acrania using two and three dimensional ultrasound

Malformations of the central nervous system are one of the most common congenital anomalies of the fetus. In this report we aimed to summarize a case of fetal acrania diagnosed in the first trimester and the use of two and three-dimensional ultrasound in early diagnosis of the disease

What is the success of ultrasonography of benign adnexal masses?

Dede, Suat/0000-0002-6846-048XWOS: 000330766900028PubMed: 24147915AimTo assess the diagnostic accuracy of the ultrasonographic discrimination of benign adnexal masses. MethodsThis was a prospective study, evaluating 245 consecutive cases using real-time gray-scale ultrasonography in a tertiary education hospital. ResultsDiagnostic accuracy was high for simple cysts and solid masses as -values of 0.824 and 0.816 and accuracy was moderate for endometriomas, dermoid cysts and cystadenomas as -values of 0.758, 0.689 and 0.627, respectively, and low for hemorrhagic cysts as a -value of 0.587. A logistic regression model was developed using ultrasonographic characteristics of the adnexal masses. Irregularity at lining of the inner wall, presence of solid component, papillary projections and echogenicity were shown to have a strong impact on the diagnosis of benign masses. ConclusionAlthough ultrasonography is a useful technique for the diagnosis of benign adnexal masses, it is limited in diagnostic accuracy. Pattern recognition is the most favored method for ultrasonographic diagnosis. Logistic regression analysis can contribute to diagnostic accuracy

Laparoscopically Assisted Vaginal Hysterectomy: Analysis of 35 Consecutive Cases

OBJECTIVE: The aim of this study was to ev aluate indications, effectiv eness and safety of laparoscopically assisted v aginal hysterectomy f or benign adnexal or uterine pathologies. STUDY DESIGN: We rev iewed the records of 35 consecutive women who underwent laparoscopically assisted v aginal hysterectomy f or benign reasons between January 2002 and December 2004. All the patients were not suitable candidates for abdominal or vaginal hysterectomy either because of concomitant adnexal masses or lack of uterine prolapse. The exclusion criteria included prolapse, uterine or adnexal neoplasm, pelv ic inflammation, vaginal stenosis and any pathology with a uterine size of more than 14 weeks. RESULTS: Indications for laparoscopically assisted v aginal hysterectomy were leiomyoma uteri (45.7%), intractable uterine bleeding (17.1%), myoma uteri with adnexal masses (14.3%), postmenopausal (8.6%) or bilateral (8.6%) adnexal masses and tamoxifen related endometrial pathology (5.7%). Mean operating time was 149.31 minutes (range 90-210) and the mean postoperative hospital stay was 2.4 days (range 2-10). Only one bladder laceration occurred during the operations which required conv ersion to laparotomy (2.8%). CONCLUSION: Laparoscopically assisted vaginal hysterectomy was f ound as a f easible and safe approach in the surgical management of a selected group of patients with benign pathologies

The parameters affecting accuracy of e ultrasonographic diagnosis in dermoid cysts

Amaç: Ultrasonografinin dermoid kist tanısındaki yeterliliğini belirlemek ve histopatolojik olarak farklı tanı alan olgularda sonografik tanısal hata nedenlerini ortaya koymak. Yöntemler: Adneksiyal kitle tespit edilen ardışık 245 olgudan ultrasonografik ve histopatolojik olarak dermoid kist tanısı alanlar çalışmaya dahil edildi. Preoperatif ultrasonografi bulguları ile postoperatif patoloji sonuçları de- ğerlendirildi ve preoperatif ultrasonografik görüntüleme ile postoperatif patoloji sonuçları arasındaki ilişki araştırıldı. Bulgular: Dermoid kist tanısı ultrasonografi ile %81,8 sensitivite, %93,1 spesifite, %67,5 pozitif öngörü değeri, %96,7 negatif öngörü değeri ile tanımlandı. Ultrasonografi ile dermoid kist tespitinde kist duvar kalınlığının 3 milimetreden fazla olmasının (p=0,029), duvar iç konturunun düzensiz olması (p=0,001) ve hiperekojenik ince çizgilenmeye bağlı olarak karışık ekojenitenin izlenmesinin (p=0,003), solid komponent (p=0,001), akustik gölgelenme (p=0,001), kalsifikasyon (p=0.001) ve ekojenik mural nodül (p=0,001) saptanmasının istatistiksel olarak anlamlı oranda yüksek olduğu görüldü. Doppler sonografide vaskularite tespitinin dermoid kist tespitinde istatistiksel olarak anlamlı olmadığı görüldü (p=0,52). Sonuç: Adneksiyel kitlelerin ultrasonografi ile subjektif olarak değerlendirilerek tanı konulmasına patern tanıma yöntemi denilmektedir. Adneksiyal kitlelerin tanınmasında patern tanıma yöntemi, diğer yöntemlere oranla yüksek doğruluk oranına sahiptir ve spesifik tanıya gitmede daha güvenilirdir. Dermoid kistlerde hiperekojenik ince çizgilenme ve hiperekojenik solid yapı karakteristik özellik olmakla birlikte, bu parametrelerin aynı zamanda yanlış tanı konulmasına sebep olan parametreler olduğu görülmüştür.Objective: To determine the adequacy of ultrasound in diagnosis of dermoid cysts and to demonstrate the causes of ultrasonographic failure in histopathologically misdiagnosed cases. Methods: Of 245 consecutive patients, whom an adnexal mass is determined and the preliminary ultrasonographic diagnosis of the cyst was a dermoid csyt, were included in the study. Preoperative ultrasonographic findings and postoperative pathology results were evaluated and the correlation with pre-operative ultrasound imaging and final pathologic results were analyzed. Results: The diagnosis of a dermoid cyst with ultrasonography was detected with the following rates of sensitivity 81.8%, specifity 93.1%, positive predictive value 67.5%, negative predictive value 96.7%. A wall thickness greater than 3 mm (p=0.029), inner wall irregularity (p=0.001), mixed echogenity according to hyperechogenic lines p=0.003), solid component (p=0.001), acoustic shadowing (p=0.001), calcification (p=0.001), echogenic mural nodule (p=0.001), were found to be statistically significant (p<0.001) in ultrasonographic diagnosis of dermoid cysts. Determination of vascularity in Doppler sonography was not found statistically significant in diagnosis of dermoid cysts (p=0.52). Conclusion: Pattern recognition method is a method that evaluates and diagnoses adnexal masses by ultrasonography subjectively. It was shown to be more reliable with high accuracy rates in specific diagnosis of adnexial masses when compared to that of other methods. Even though hyperechogenic lines and hyperechogenic solid masses were characteristic findings for dermoid cysts, these parameters were found to be the most frequent causes of misdiagnosis
