Background: Placental transmogrification of the lung is a very rare benign disease with characteristic finding being alveoli resembling chorionic villi placenta. The purpose this study was to assess computed tomography (CT) findings placental in six patients and their relation histopathologic findings.

OBJECTIVE To assess the role of ultrasound in detecting the migration of placenta previa during the third trimester at Lady Willingdon Hospital and Jinnah Hospital, Lahore during the period July 2000 to September 2002. METHODS Eighty pregnant women with the diagnosis of placenta previa at 28 to 32 weeks of gestation were included in the study. After base line ultrasound, scan was repeated eve...

The placenta grows rapidly for a short period with high blood flow during pregnancy and has multifaceted functions, such as its barrier function, nutritional transport, drug metabolizing activity and endocrine action. Consequently, the placenta is a highly susceptible target organ for drug- or chemical-induced adverse effects, and many placenta-toxic agents have been reported. However, histopat...

OBJECTIVE While delayed umbilical cord clamping (UCC) is thought to facilitate placental to infant blood transfusion, the physiological factors regulating flow in the umbilical arteries and veins during delayed UCC is unknown. We investigated the effects of gravity, by changing fetal height relative to the placenta, and ventilation on umbilical blood flows and the cardiovascular transition duri...

Nitric oxide (NO) production in the rat placenta was monitored and quantified by electron paramagnetic resonance (EPR) spectroscopy with hemoglobin and an Fe-N-(dithiocarboxy)sarcosine (DTCS) complex as NO-trapping reagents. Expression of nitric oxide synthase (NOS) isoforms was also examined by quantitative RT-PCR analysis. The EPR spectrum of the placenta with hemoglobin trapping showed a thr...

Annular placenta is an extremely rare morphological type of human placenta. It is commonly related to placental vessel abnormalities frequently causing antenatal and postnatal hemorrhage and operative delivery. Gravida 4 para 1 had an uneventful course of pregnancy and normal vaginal delivery followed by moderate postpartum hemorrhage. Hemorrhage was found to be local in origin but the placenta...

Objectives Although adenomyosis is reportedly associated with adverse pregnancy outcomes, clinical factors related to the high risk of obstetric complications are unclear. This study aimed elucidate characteristics lesions increased incidence based on imaging findings.Methods was a retrospective, observational cohort conducted in tertiary perinatal care center. Eighty-eight singleton pregnant w...

The above quote testifies to the complexity of preterm labour, a process that ultimately results in considerable neonatal morbidity and mortality. It is diYcult to quantify the incidence of spontaneous preterm labour, as many studies relating to preterm birth do not discriminate between spontaneous preterm labour and iatrogenic/therapeutic preterm delivery. The picture is further complicated as...

The risk of hypertension is increased by intrauterine growth restriction (IUGR) and preterm birth. In the search for modifiable etiologies for this life-threatening cardiovascular morbidity, a number of pathways have been investigated, including excessive glucocorticoid exposure, nutritional deficiency and aberration in sex hormone levels. As a neurotrophic hormone that is intimately involved i...
