Randomized Controlled Trial Comparative Study Clinical TrialA comparative study of the effect of high-intensity transcutaneous nerve stimulation and oral naproxen on intrauterine pressure and menstrual pain in patients with primary dysmenorrhea.
Our purpose was to compare the effects of high-intensity transcutaneous electrical nerve stimulation and oral naproxen (500 mg) on intrauterine pressure and menstrual pain. ⋯ Treatment with transcutaneous electrical nerve stimulation induced a prompt onset of pain relief without any significant changes in uterine activity. Possible mechanisms for the pain relief, decreased uterine ischemia or decreased activity in the pain transmission system at spinal or supraspinal levels, are discussed.

Randomized Controlled Trial Clinical TrialAntenatal vitamin K therapy of the low-birth-weight infant.
The purpose of our study was to determine whether maternal vitamin K1 administered antenatally improved global coagulation parameters and the levels of specific vitamin K-dependent proteins in low-birth-weight infants. ⋯ These results would suggest that antenatal vitamin K1 therapy to mothers < 32 weeks' gestation has no significant effect on the level of vitamin K-dependent factors in the fetus.

Comparative StudyA comparison of propylthiouracil versus methimazole in the treatment of hyperthyroidism in pregnancy.
Our purpose was to demonstrate that propylthiouracil and methimazole are equally effective and safe in the treatment of hyperthyroidism during pregnancy. ⋯ Propylthiouracil and methimazole are equally effective and safe in the treatment of hyperthyroidism in pregnancy.

Fetal fibronectin in patients at increased risk for premature birth.
The objective of this study was to evaluate fetal fibronectin as a screening test for subsequent preterm birth in asymptomatic pregnant women. ⋯ Fetal fibronectin in the cervicovaginal secretions of asymptomatic patients has potential value as a screening test in the identification of patients at risk for preterm birth. This test had equally high sensitivity and negative predictive value for birth before 37 weeks.
