Perinatal outcomes of sonographically detected nuchal cord in southeastern Turkey.

PURPOSE: To investigate the outcomes of pregnancies with a sonographically detected nuchal cord (NC) from a single center in south-eastern Turkey. MATERIALS AND METHODS: A retrospective study was carried out at Maternity and Child Health Hospital Diyarbakir, Turkey, between 2011 and 2013. A-total of 477 pregnancies with sonographically detected NC during the second and third trimesteri of gestation (20-40 weeks) were included. The control group consisted of 1,043 randomly selected pregnancies without NC matched for gestational age at the time of ultrasound examination. Outcome variables, including maternal age, parity, gestational age at delivery, mnode of delivery, intrapartum fetal heart abnormalities, meconium-stained amniotic fluid, birth weight, and one- and five-minute Apgar scores, were compared between the two groups. RESULTS: There were no statistically significant differences in any of the outcome variables between patients with sonographically detected NC and controls. CONCLUSIONS: The presence of NC indicates a need for increased care but is not associated with adverse perinatal outcomes.

Emergency peripartum hysterectomy: our experience.

PURPOSE: To investigate the incidence of and reasons for emergency peripartum hysterectomy (EPH) between 2009 and 2013 in our hospital, one of the three hospitals with the highest rates of delivery in Turkey. METHODS: A retrospective study. Seventy-six peripartum hysterectomies were evaluated. We compared the modes of delivery and examined whether bilateral internal iliac artery ligation was performed. RESULTS: The incidence of EPH was 0.77 in 1000. The majority of cases involved multiparity, uterine rupture, placenta praevia, or placental invasion abnormalities. The most frequent reason for EPH was uterine atony (64.5 %). There was no statistically significant relationship with mode of delivery; however, the complication rate and requirement for fresh frozen plasma were significantly (p < 0.01) related to whether bilateral internal iliac artery ligation was performed. CONCLUSION: Uterine atony was the most common indication for EPH. The most important step to avoid performing EPH is to calculate patients' risks for postpartum bleeding. Postpartum haemorrhage may not be preventable, but when it happens, obstetricians must be prepared to perform EPH, and in high-risk patients, to perform internal iliac artery ligation.

Expression of VEGF and CD68 in the placenta of gestational diabetic mothers (immunohistochemistry and ultrastructural study) / Expresión de VEGF y CD68 en la placenta de madres diabéticas gestacionales (estudio inmunohistoquímico y ultraestructural)

Placental angiogenesis, is essential for embryonic and fetal development. In this study, 18 gestational diabetes mellitus and 22 control pregnancies were included. Gestational diabetes mellitus (GDM) groups compared to the control group significantly higher values were detected (p<0.01). The following histological results were assessed; villous immaturity, chorangiosis, presence of, sncytial knots,mononuclear cell infiltration ischemia and fibrinoid necrosis. To evaluate and compare the placental histology of normal and GDM pregnancies. placentas of pregnant women with gestational diabetes also in terms of angiogenesis and macrophages and ultratructural revealed by examining the possible relationship between fetal complications were investigated.

La angiogénesis de la placenta es esencial para el desarrollo embrionario y fetal. En este estudio, se incluyeron 18 casos de diabetes mellitus gestacional (DMG) y 22 embarazos de control. En grupos los de DMG en comparación con el control, se detectaron valores significativamente mayores (p<0,01) en los siguientes parámetros histológicos que fueron evaluados: inmadurez vellosa, chorangiosis, presencia de nodos sincicial, infiltración celular isquémica mononuclear y necrosis fibrinoide. La investigación de las placentas de mujeres con DMG, reveló mediante el examen en términos de angiogénesis, macrófagos y ultraestructural, la posible relación entre las complicaciones fetales.

Expression of human chorionic gonadotropin (ßhCG) in pre-eclamptic placenta / Expresión de gonadotropina coriónica humana (ßhCG) en placenta preeclámptica

This study aimed to assess association between preeclampsia with trophoblast cells and serum level of b-human chorionic gonadotropin (ß-hCG). Were compared 20 patients with preeclampsia and 20 control patients with respect to demographics, hematological parameters and the presence of trophopblast in placental samples. Patchy necrosis with loss of microvilli and gross thinning of the syncytium with distorted microvilli were seen in terminal villi of placentae of women with pre-eclampsia Syncytial cells at the molecular level crossings, especially at the level of ßhCG in conjunction with the changes in the preeclampsia was made on the histopathological changes to clarify the villi.

El objetivo fue evaluar la asociación entre la preeclampsia con células trofoblásticas y concentración sérica de la gonadotropina coriónica humana b (ß-hCG). Se compararon 20 pacientes con preeclampsia y 20 pacientes de control con respecto a datos demográficos, parámetros hematológicos y la presencia de trofoblasto en muestras de placenta. Se observaron áreas dispersadas de necrosis, con pérdida de microvellosidades y adelgazamiento del sincitio con microvellosidades distorsionadas en las vellosidades terminales de placentas en mujeres con células sincitiales preeclámticas a nivel molecular, junto a altos niveles de ßhCG asociados a los cambios generados por la preeclampsia sobre los parámetros histopatológicos.

Expression of PECAM-1 and E-Cadherin in the Umblical Cords of Gestational Diabetic Mothers / Expresión de PECAM-1 y E-cadherina en los Cordones Umbilicales de Madres con Diabetes Gestacional

The purpose of this study is to examine the changes in the umbilical cord in women diagnosed with gestational diabetes mellitus In this study, as a control group human placental tissues from normotensive pregnancies was collected from diabetic women at 28­35 weeks of gestation. Gestational diabetes (n= 20) and normal umbilical cord (n= 20) for a total of 40 units were received.GDM groups compared to the control group was significantly higher values was detected (p<0.01). In GDM group, light microscopy showed erosion of the endothelium and complete rupture of theumbilicalvessels resulting in extravasation of blood within Wharton's jelly. it was observed that the cytoplasmic fragments and cell infiltration of the spill to the subepithelial layer of apoptotic cell PECAM-1 positive reaction showed. E-Cadherin in endothelial side surface of diabetes group showed weak expression in the nucleus and showed positive reaction in smooth muscle.

El objetivo fue examinar los cambios que presenta el cordón umbilical de mujeres con diagnóstico de diabetes mellitus gestacional (DMG). Se incluyeron en el grupo control muestras de tejidos placentarios humanos de embarazos normotensos y de mujeres diabéticas de entre 28­35 semanas de gestación. Las muestras se divieron en cordones umbilicales con cambios de DMG (n= 20) y cordones umbilicales normales (n= 20), constituyendo un total de 40 muestras. El grupo de DMG, en comparación con el grupo control, presentó valores significativamente más elevados (p<0,01). En el grupo de DMG, la microscopía óptica demostró la erosión del endotelio y la ruptura completa de los vasos umbilicales, resultando en la extravasación de sangre dentro de la gelatina . Se observaron fragmentos citoplasmáticos e infiltración celular de la capa subepitelial de células apoptóticas mostró una reacción positiva a PECAM-1. En el grupo de DMG, la E-cadherina de la superficie lateral endotelial mostró una expresión débil en el núcleo y una reacción positiva en el músculo liso.

Ultrastructural effects of the propineb on brain of fetuses during rat pregnancy / Efectos ultraestructurales de propineb en el cerebro de fetos durante el embarazo de ratón

Propineb is a fungicide with a propylene-bis-dithiocarbamate structure. Pregnant Wistar rats were exposed to 400 ppm propineb concentrations in 5 ml distilled water, 5 days per week until the end of pregnancy. The rats were treated with propineb for 16 days and the brains of litter rats were sacrificed at first day of birth after which their brains were collected. Ultrastructural examination of the brains of the fetuses and propineb-treated pregnant females revealed a variety of histopathological effects. We suggest that mitochondrial damage may be an effective factor for neuron necrosis. These results supported the proposal that the exposure to fungicides such as propineb and to other naturally occurring compounds which inhibit mitochondrial function, may contribute to Parkinson's disease development.

El Propineb es un fungicida con una estructura de propileno-bis-ditiocarbamato. Ratas Wistar preñadas fueron expuestas a concentraciones de depropineb (400 ppm) en 5 ml de agua destilada, 5 días por semana hasta el final de la preñez. Las ratas fueron tratadas por 16 días y las crías fueron sacrificados el primer día de nacimiento para recolectar sus cerebros. El examen ultraestructural de los cerebros de los fetos y las hembras preñadas tratadas con propineb reveló una variedad de efectos histopatológicos. Sugerimos que el daño mitocondrial puede ser un factor eficaz para la necrosis neuronal. Estos resultados apoyaron la propuesta de que la exposición a los fungicidas tales como propineb y de otros compuestos de origen natural que inhiben la función mitocondrial, puede contribuir al desarrollo de la enfermedad de Parkinson.
