Blood flow Doppler velocimetry measured during active labor.

Purpose: To evaluate blood flow Doppler velocimetry during the first and second stages of active labor.

Methods: A prospective observational study was performed. Patients at term (37-42 weeks gestation), with normal fetal heart rate tracing patterns (categorized as category I) were examined during the first and second stages of labor.

Third-trimester abnormal uterine artery Doppler findings are associated with adverse pregnancy outcomes.

Objectives: To evaluate the association between third-trimester abnormal uterine artery Doppler findings and pregnancy outcomes.

Methods: A prospective study was designed, including 198 consecutive singleton pregnancies between 27 and 41 weeks' gestation. In the study population, 144 had normal uterine artery Doppler waveforms, 37 had unilateral pathologic waveforms, and 17 had bilateral pathologic waveforms.

Association between first trimester vaginal bleeding and uterine artery Doppler measured at second and third trimesters of pregnancy.

Objective: To evaluate the prevalence of first trimester vaginal bleeding among patients with abnormal second and third trimester uterine artery Doppler.

Methods: A prospective study of patients with a uterine artery Doppler measurement between 27 and 42 weeks' gestation was undertaken. A comparison was made between two groups: patients with and without first trimester vaginal bleeding.

[Warning labels on medications--influence of warning labels and physicians' orders on patient behavior].

Compliance of 40 mothers with a warning label, "for external use," on a medicine package was checked in a survey in a primary care clinic for children. We also checked parents' attitudes to giving a medicine to their child when instructions given by the physician or by a friend contradicted the printed warning on the label. All mothers who were told that the medicine was recommended by their physicians accepted the recommendation without hesitation.

Acute renal failure in a patient with prostatic carcinoma. A case of benign uropathy.

Obstructive uropathy and renal insufficiency are often associated with cancer. However, in the case described here, a patient with carcinoma of the prostate had acute renal failure due to benign obstructive uropathy. Precise, prompt diagnosis and treatment resulted in complete reversal of renal symptoms.
