Plasma volume (PV) expansion is required for optimal pregnancy outcomes; however, the mechanisms responsible for sodium and water retention in pregnancy remain undefined. This study was designed to test the "arterial underfill hypothesis" of pregnancy which proposes that an enlarged vascular compartment (due to systemic vasodilation and shunting of blood to the placenta) results in renal sodium...

As early as 1901, DeLee described a hemophilic-like condition of the blood in abruptio. Dieckmann in 1936, studying a group of patients with abruptio, found fibrinogen concentration below the normal levels in seven out of eleven cases, and in three where the fibrinogen level was below 50 mg./100 c.c. During the past few years hypofibrinogenemia has been shown to exist in other conditions apart ...

because of an unknown factor, the frequency of complicated pregnancy with placenta previa has been raised during past decade. this study was designed to deepen our understanding of risk factors and outcomes of placenta previa in our country. this study investigated 694 cases of placenta previa comparing with 600 healthy pregnant women with not overlie placenta in two referral and tertiary obste...

to investigate the effects of certain factors on the rate of retained placenta, 2844 calving records from 1288 holstein cows in a herd were used. these cows calved during year period of 2001 to 2007. a generalized statistical linear model was applied to analyze the data. logistic regression model was applied as the statistical model. in the model, fixed effects of year, season (warm or cold) an...

background & aim: cervical ectopic pregnancy is a rare variant of ectopic pregnancy, and placenta percreta is a complex and dangerous condition; patients with these conditions are difficult to manage. in this study, we present a rare case of placenta percreta in cervical pregnancy. case report: a 32 -year-old woman with 19 weeks of gestation and gross hematuria was admitted to qaem hospital in ...

pedunculated chorangioma is extremely rare type of chorangioma. to the best of our knowledge, no case has been reported in indian literature. we report one such rare case in a twenty two year old primi gravida who delivered a full term live female baby by lower section caesarian section (lscs). gross examination revealed a nodular mass attached to the placenta by a pedicle. histopathological ex...

Background: Placenta accreta is one of the known causes of maternal mortality and morbidity. If diagnosed before delivery, appropriate actions can be taken. The aim of this study was to investigate the role of scaling combination of risk factors in predicting placenta accreta spectrum (PAS). Methods: In this cross-sectional study, 120 pregnant women with two criteria and more of placenta previ...

INTRODUCTION Uterine atony is the most common cause of primary post partum haemorrhage. We report a case where this was complicated by two rare conditions, platelet storage pool disease and placenta diffusa. Platelet storage pool disease is a platelet aggregation disorder associated with mild to moderate bleeding diathesis. There are limited cases reported in pregnancy. Placenta diffusa is a ra...

Radiata pine is the main wood species used in Chilean construction industry, but it must be protected due to its low natural durability. Chemical protection of by impregnation allows for a more efficient utilization forest resources extending useful life. The use nanoparticles has garnered great interest during last decade, their unique physicochemical properties, different from those larger si...

amiodarone is used in treatment of cardiac arrhythmias. therapeutic use of amiodarone is limited by its side effects, including pulmonary toxicity. human placenta extract (hpe) contains a variety of bio-active substances. thus, the present study aimed to quantitatively evaluate the protective effects of hpe on the structural lung changes induced by amiodarone using stereological methods. spragu...
