BACKGROUND: The obstetrics and gynecology literature has expanded in recent years to include clinical trials assessing the use of barbed sutures. The difficulty of intracorporeal suturing continues to be a barrier to a wider use of laparoscopy. Although the use of barbed sutures has been shown to ease the process of laparoscopic suturing considerably, concerns have been raised regarding a potentially increased risk of adhesions or inflammation as a result of their use. OBJECTIVES: The aim of this study was to determine whether differences in surface textures, resulting from the variations in the geometric configurations of barbs, lead to differences in intra-abdominal adhesion formation...

BACKGROUND: Endometrioid ovarian carcinoma and clear cell ovarian carcinoma are both classified as endometriosis-associated ovarian cancers (EAOCs). Despite the high rates of recurrence and mortality of EAOC, only a few prognostic biomarkers have been reported. Mitochondrial superoxide dismutase (SOD2) plays an important role in maintaining mitochondrial function through oxidative stress tolerance and contributes to chemotherapeutic resistance. METHODS: To clarify the clinical significance of SOD2 in EAOC, SOD2 expression was semi-quantitatively investigated by immunohistochemical analysis in 61 primary EAOC cases, and the correlations between SOD2 expression and clinicopathological data and survival were analyzed...

Stillbirth is a sudden and painful event for parents and obstetrical specialists as well. It is, therefore, of greatest importance to be able to give answers for the cause in order to plan a subsequent pregnancy. The aim of this retrospective study is to estimate the placental and umbilical cord cause of intrauterine death in relation to different gestational ages. The study took place on the Medical Birth Registry of Aretaieio Hospital, National and Kapodistrian University, Athens, Greece. We include a total of 19,283 pregnancies from 1998 to 2012...

PURPOSE: Cervical cancer (CC) is the most common cancer affecting women worldwide. Human papillomavirus (HPV) infection is a major contributing factor for the development of CC. The development of CC occurs progressively from precancer stages to cancerous stages (ie, invasive squamous cell carcinoma [ISCC] and adenocarcinoma [ADC]). ADC is a rare form of CC that develops from the mucinous endocervical epithelium. It is believed that the downstream targets of Notch signaling contribute to the etiology of CC...

INTRODUCTION: Unforeseen emergency in late pregnancy can be catastrophic and cause unexpected maternal and foetal demise. Moreover, lack of awareness and failure of prompt treatment raise mortality rate. Such fatalities warrant a forensic autopsy as it may raise redundant medico-legal concerns. CASE REPORT: We report a case that revealed significant intra-abdominal haemorrhage at autopsy. The source of haemorrhage was at the spleen hilum and histology established rupture of splenic artery aneurysm...

INTRODUCTION: Reference ranges in fetal postmortem anthropometric data derive from heterogeneous studies and rely on data obtained after intrauterine fetal death and abortion, which may introduce bias in the reported fetal growth parameters. We report anthropometric findings in fetuses with the least variation due to cause of death or developmental anomalies. METHODS: We analyzed fetuses after the termination of pregnancy for psychosocial reasons. The external measurements, X-ray dimensions, and body and organ weights were recorded as well as the placenta weight...
