Elli beş yaşındaki bir kadında ki-67 ekspresyonu olmamasının düşük malign potansiyeli yansıttığı muhtemel olarak wolffian kaynaklı dişi adneksial tümör
Female adnexial tumors of probable Wolffian origin (FATWO) are rare tumors derived from the remnants of the mesonephric duct. These tumors generally exhibit a low malignant potential, but recurrence and or metastasis is possible during the course of the disease according to the tumors’ possible malignant potential. We report a case of FATWO without estrogen and progesterone receptors and with negative immunostaining for Ki-67 (a proliferation marker) as a probable low-malignant-potential tumor. A 55-year-old woman presented with a complaint of heavy menstrual bleeding and pelvic pain. Preoperative ultrasonographic evaluation revealed an intramural uterine leiomyoma of 4 cm in diameter and a right adnexial solid mass measuring 5 cm in diameter. Following total abdominal hysterectomy and bilateral salpingo-oophorectomy, immunostaining based on the labeled streptavidin-biotin method was performed on sections from representative blocks of paraffin-embedded tissues sampled from the mass, revealing a low mitotic index with negative Ki-67 immunostaining. Immunohistochemical staining with promising new markers and pathological investigation of the entire tumor are needed to determine the malignant behavior of an individual FATWO. Ki-67 is a helpful marker for determining Wolffian duct tumors’ potential malignant behavior
The outcomes of surgical treatment modalities to decrease "near miss" maternal morbidity caused by peripartum hemorrhage
BACKGROUND: The treatment of patients with peripartum hemorrhage is unfortunately characterized by inadequate treatment that does not adhere to standard therapeutic measures. AIM: Assessment of different management strategies among patients with severe hemorrhage, particularly the ones with "near-miss" maternal morbidity and mortality to establish clinically useful guidelines for the prevention and management of peripartum hemorrhage. PATIENTS AND METHODS: In this study, the medical records of 458 patients who have experienced peripartum hemorrhage between March 2009 and March 2012 in a tertiary perinatal center were retrospectively reviewed. Specific surgical treatment modalities utilized to 61 patients with severe peripartum hemorrhage with respect to the procedure timing and effectivity were compared according to the outcomes and efficiency. RESULTS: Sixty-one patients who have been diagnosed as severe peripartum hemorrhage have been included to the study. Six (75%) of the 8 patients who were treated with B-Lynch brace suture for uterine atony and 9 (60%) of the 15 patients who were treated with the Bakri balloon tamponade system for uterine atony or placenta accreta required hysterectomy following the initial therapeutic measures. The patients who have been treated with bilateral hypogas-tric artery ligation and B-Lynch brace suture or Bakri balloon uterine tamponade system were less likely to need a complementary hysterectomy for definitive treatment of peripartum hemorrhage when compared with patients treated with either B-Lynch brace suture or Bakri uterine tamponade balloon system alone. CONCLUSIONS: The efficiency of B-Lynch compression brace sutures and the Bakri balloon uterine tamponade system is unpredictable in terms of the need for hysterectomy for peripartum hemorrhage patients diagnosed as either uterine atony or placenta previa. Regardless of the initial diagnosis, these modalities seem to be more effective in alleviating peripartum hemorrhage when accompanied by hypogastric artery ligation
Prevention of adhesion formation in wistar-albino rats by increased bowel movements achieved with oral ricinus oil use for 8 days postoperatively: an experimental study
Objective: Adhesion formation frequently occurs after abdominopelvic surgery and can cause significant morbidity for patients. Meticulous hemostasis, minimal access surgery and utilization of surgical adjuvants intraoperatively are clinically useful measures to minimize adhesion formation. We investigated the clinical efficiency of oral Ricinus oil treatment for 8 days postoperatively to decrease adhesion formation in this case-control study in a rat model. Study design: Following computer-generated randomization, 24 female Wistar-albino rats were operated on, with 10 standard cautery lesions on the right uterine horn and two simple suture lesions on left uterine horn generated with absorbable material. Half (n = 12) the rats received 0.13 g (0.2 ml) Ricinus oil emulsion (40 g/60 ml) via the oral route during the first 8 days postoperatively, and the remaining rats (n = 11) were considered as controls. The extent, severity, degree, total adhesion scores and histopathological features of the adhesions were the main outcome measures. Results: The degree and total adhesion formation scores in the Ricinus oil group and control group revealed significant differences in adhesion extent and severity. The total adhesion scores of the Ricinus oil and control groups were 3.00 +/- 2.21 and 5.18 +/- 2.78 respectively (P 0.05). Conclusions: Ricinus oil treatment following abdominopelvic surgery for the 8-day period that covers the completion of tissue healing process may be a promising, cheap and cost-effective treatment strategy for patients.

FİNANSAL VARLIK FİYATLARINDAKİ DEĞİŞME - PARASAL BÜYÜKLÜKLER ETKİLEŞİMİ
ABSTRACT The aim of this study is to reveal whether the monetary aggregates and their components obtained from the CBRT balance sheet have long memory, and to analyze empirically whether these aggregates can be used as policy target. The empirical part of the study at hand consists of fractional analysis in the economic time series.Bu çalışmanın amacı, TCMB bilançosundan elde edilen parasal büyüklüklerin ve bunları oluşturan bileşenlerinin uzun hafızaya sahip olup olmadıklarını ortaya koymak ve bu büyüklüklerin bir politika hedefi olarak kullanılıp kullanılmayacağını, ampirik olarak analiz etmektir. İktisadi zaman serilerinde, fractional (parçalı) yapıya dayalı, test ve analiz yöntemleri, bu çalışmanın ampirik boyutuna taban oluşturmaktadır
