Introduction. Meckel's diverticulitis is an extremely rare cause of an acute abdomen in pregnancy. Its clinical presentation tends to be rather unusual and therefore commonly delaying diagnosis. The surgical method of exploration can be either by laparoscopy or through an open incision. Case Report. We report a case of a 34-year-old, P1 with previous Caesarean section, who presented at 20 weeks...

OBJECTIVE To determine the incidence and clinical characteristics of persistent left superior vena cava (PLSVC) among low-risk pregnancies. We have also compared electrocardiography (ECG) parameters of infants with PLSVC with those of normal controls. METHOD At our institute, fetal echocardiogram is routinely performed in the midtrimester. We retrospectively reviewed the records of prenatally...

The effect of O2 on surfactant protein (SP) A mRNA transcription and half-life was determined in midtrimester human fetal lung tissue cultured in either 20 (control) or 70% O2. Incubation of tissues in 70% O2 resulted in a 133% increase in SP-A mRNA transcription rate compared with control tissues. The SP-A mRNA half-life was increased by 54% in lung tissues cultured in 70% O2 vs. control tissu...
