A Biometrical study was conducted on the digestive tract of 35 foetuses of the one-humped camel collected from the Sokoto metropolitan abattoir, over a period of five months at different gestational ages. The approximate age of the foetuses was estimated from the crown vertebral rump length (CVRL) and samples were categorised into first, second and third trimester. The mean body weight of the f...
BACKGROUND It is uncertain how best to screen pregnant women for the presence of fetal Down's syndrome: to perform first-trimester screening, to perform second-trimester screening, or to use strategies incorporating measurements in both trimesters. METHODS Women with singleton pregnancies underwent first-trimester combined screening (measurement of nuchal translucency, pregnancy-associated pl...
The incidence of multifetal pregnancies has increased dramatically over the past two decades, mainly because of the widespread use of ovulation induction agents and assisted reproduction techniques. These techniques have been a matter of concern since twin and higher order pregnancies have long been associated with an increased risk of maternal complications as well as a high prevalence of pren...
Oligohydramnios developing early in pregnancy is less common, and the fetal outcomes are usually poor. This is because prolonged decrease in amniotic fluid may cause compression sequences, such as pulmonary hypoplasia, muscle hypotrophy or joint constriction. Early-onset oligohydramnios may be caused by preterm premature rupture of membranes (pPROM) or decreased secretion of amniotic fluid. Ear...
ARQUIVOS DE MEDICINA, 22(4/5):121-2 Amniocentesis is a safe procedure with low risk for complications including infection. A case of genetic amniocentesis followed by Escherichia coli sepsis is reported. Bacteriological data showed positive blood cultures to Escherichia coli. The mechanisms of infection are discussed: contamination from the instruments, systemic dissemination of bacteria coming...
Normal pregnancy is associated with intense alterations in the maternal cardiovascular system. The aim of the present study was, to assess the influence of normal pregnancy on maternal central aortic pressures, arterial stiffness, and arterial wave reflection using non-invasive PC based cardiovascular risk analysis system (Periscope). The current study was conducted on 137 women with, normotens...
Objective: This study was designed to test the null hypothesis that first trimester ultrasound crown-rump length measurement for gestational age determination will result in no difference in the rate of induction of labor for postterm pregnancy, compared with second trimester biometry alone. Study design: Two hundred eighteen women were randomly assigned to receive either first trimester ultras...
[Purpose] The aim of this study was to investigate the changes in pain intensity, spinal curvature, and balance and gait ability according to the pregnancy period. [Subjects] Nineteen pregnant women and fifteen nonpregnant women were recruited in this study. [Methods] The pain intensity, spinal curvature, gait, and balance of pregnant women were measured according to the pregnant period (2nd an...
