Case ReportsSuccessful treatment with carbimazole of a hyperthyroid pregnancy with hepatic impairment after propylthiouracil administration: a case report.
We report the case of a 27-year-old woman with hyperthyroidism during pregnancy. Antithyroid treatment with propylthiouracil (PTU) resulted in elevated hepatic enzymes and after the 12th week of pregnancy treatment was changed to carbimazole (CBZ). The remaining pregnancy, delivery and follow-up period were uneventful for the mother and her offspring. Antithyroid treatment during pregnancy should allow the use not only of PTU but also of CBZ and methimazole.

Comparative Study Clinical Trial Controlled Clinical TrialSpinal versus general anesthesia for elective cesarean delivery: a prospective comparative study.
To study the efficacy and safety of spinal anesthesia for elective cesarean section as compared with general anesthesia. ⋯ Spinal anesthesia is as effective as a general anesthesia. Maternal and fetal outcome are favorable. Maternal hypotension can be managed successfully with modest doses of ephedrine and IV fluid infusions. It provides sufficient postoperative analgesia allowing the mother to have more vitality and comfort than those who receive general anesthesia.

Doppler velocimetry and non stress test in severe fetal growth restriction.
The aim of our study was to evaluate the efficacy of Doppler velocimetry and cardiotocography in surveillance of the fetus affected by severe fetal growth retardation (FGR) and hence their capacity in predicting adverse perinatal outcome. This could therefore permit the timing of delivery thus reducing perinatal morbidity and mortality. ⋯ The data presented show that velocimetric modifications in the fetal venous compartment constitute a relevant prognostic sign in the prediction of perinatal mortality and neonatal resuscitation. The further the vessels compromised are from the heart, the higher is the relative risk for perinatal mortality, equal to 5.0 (95% C.I. = 0.61-40.9) with alterations on the IVC, of 8.2 (95% CI = 1.04-61.5) when they involve the DV, and of 18.0 (95% = 2.44-133) when pulsations are obtained on the UV.

Expression of laminin, type IV collagen and fibronectin molecules is related to embryonal skin and epidermal appendage morphogenesis.
Basement membrane zones are specialized sheets--like arrangements of extracellular matrix proteins and glycosaminoglycans, and act as an interface between parenchymal cells and support tissue. They separate epithelium, endothelium, muscle cells and Schwann cells from adjacent connective tissue stroma, and also from a limiting membrane in the central nervous system. They are involved in several cellular and biological processes, including adhesion, migration and cellular differentiation. ⋯ We studied immunohistochemically the origin, the first appearance and distribution of the adhesive extracellular glycoprotein laminin and the fibrillar proteins of the extracellular matrix collagen type IV and fibronectin in the basement membranes of fetal human skin between 12 to 21 weeks of gestational age. Additionally, we studied the expression of vimentin in the extracellular matrix of the epithelial/mesenchyme junction of the skin. This study demonstrates clearly that the expression of the antigens laminin, collagen type IV and fibronectin starts in the germinative epithelial cells of the skin at the bulbs of the hair follicles (12th week for fibronectin and 19th week for laminin and collagen type IV), and migrating progressively involves the epithelial epidermal cells of the covering skin, as well as, the basement membrane at the dermal-epidermal junction in that region (between 20 to 21 weeks of gestational age).

Randomized Controlled Trial Comparative Study Clinical TrialA randomized trial of pulsatile vs continuous oxytocin infusion for labor induction.
In a prospective randomized study, 560 pregnant women were subjected to labor induction with continuous or pulsed intravenous oxytocin infusion. There were no significant differences with respect to maternal history, Bishop score and perinatal morbidity. ⋯ The mean amount of oxytocin administered in the pulsed infusion group was also significantly lower than in the continuous infusion group (4.7 +/- 0.6 mU/min versus 9.6 +/- 3.4 mU/min in primiparous, p < 0.001 and 2.1 +/- 0.4 mU/min versus 5.2 +/- 2.3 mU/min in multiparous women, p < 0.001). Our study demonstrates that pulsatile administration of oxytocin is as safe as continuous intravenous infusion, requires less oxytocin and is more effective as it reduces labor duration.
