Attitudes of patients one year after vasectomy: results of 355 of 1,000 questionnaires.

The results of 355 questionnaires are reported, returned one or more years after vasectomy from 1,000 consecutive patients undergoing vasectomies performed by the author from 1959 to 1972. A majority claimed either unchanged or improved health, satisfaction with sexual relations, and frequency of sexual intercourse; 99.5 per cent were satisfied with the operation and in retrospect 96.

Urinary excretion of adenosine 3',5'-monophosphate and guanosine 3',5'-monophosphate in normal children and those with cystic fibrosis.

The urinary excretion of adenosine 3',5'-monophosphate (cyclic AMP) and guanosine 3',5'-monophosphate (cyclic GMP) was examined in 98 normal children and 46 children with cystic fibrosis between the ages of 9 months and 18 yr. Diurnal variations in cyclic AMP and cyclic GMP excretion were observed in subjects from either group, and peak levels of cyclic nucleotide excretion were generally observed during the period of 0700 to 2100 h. Excretion rates (mumol/day) of cyclic AMP and cyclic GMP increased significantly with age.

Gonorrhea detection in a family planning clinic: a cost-benefit analysis of 2,000 triplicate cultures.

Among 2,019 women screened by triplicate culture technique, 191 (9.5 per cent) had one or more positive cultures of specimens for Neisseria gonorrhoeae. The prevalence rates by site of infection were as follows: cervix-8.

Nest parasitism, productivity, and clutch size in purple martins.

Mean maximum nestling weight of purple martins decreased with increase in brood size from three to five. Martins in the absence of acarine nest parasites produced young heavier than parasitized young of the same brood size; in addition, unparasitized nestlings tended to reach a maximum weight equivalent to that of young in parasitized broods of one less member. Modal brood size for parasitized and unparasitized martins was four, but there was a significant trend toward production of broods of five by mite-free birds, and of broods of three by parasitized parents.
