Oral contraceptives reduce menstrual pain but the interaction with vasopressin and prostaglandin F2 alpha, two uterine stimulants related to the condition, is unknown. Ten women with a history of moderate to severe dysmenorrhoea were studied. Repeated blood samples were taken during a first menstrual cycle without treatment, during the first 21 days of a second cycle when they received an oral contraceptive (150 micrograms levonorgestrel and 30 micrograms ethynyloestradiol) and on the first or second day of the bleeding following hormonal withdrawal. ⋯ M.) pmol/l) and at ovulation in the control cycle (1.91 +/- 0.58 pmol/l). During treatment the concentrations were consistently low, except on the first day of withdrawal bleeding (2.33 +/- 0.35 pmol/l). The concentrations of the prostaglandin F2 alpha metabolite showed less variation, but again the values at withdrawal bleeding (271 +/- 39 pmol/l) were not different from those obtained over the painful menstruations (255 +/- 24 and 217 +/- 25 pmol/l).(ABSTRACT TRUNCATED AT 250 WORDS)

First year mortality and hospital morbidity were studied in 4678 surviving infants liveborn at National Women's Hospital during 1980, of whom 1113 had been admitted to the neonatal intensive care unit. Of children born there, but never admitted to the neonatal unit, 8.3% were hospitalised in their first year for a mean of 6.7 days per admission or 0.8 days per child. Hospitalisation rates were increased in neonatal unit survivors, ranging from 11.6% in normal birthweight to 15.5% in very low birthweight survivors. ⋯ Deaths in normal birthweight survivors were due to congenital abnormalities. No VLBW survivor died after discharge from National Women's Hospital. Children surviving neonatal unit care in Auckland in 1980 appeared to have less continuing first year morbidity and mortality than has been reported elsewhere.

One hundred men with proven fertility who presented for vasectomy consultation were examined for testicular size and presence of a varicocele, including examination with the Doppler stethoscope for the presence of subclinical varicocele. A diagnosis of varicocele was established in 61%. ⋯ It is apparent that varicoceles, especially subclinical varicoceles, are an extremely common finding, even in a group of fertile men. The results suggest that subclinical varicoceles have no role in male infertility.
