Time utilization of a population of general surgeons in a prepaid group practice

Seven general surgeons in a prepaid group practice previously shown to have a mean operative work load of 9.2 hernia equivalents (HE) per week were found to have a standardized mean daytime working week of 56.2 hours, exclusive of evening activities of which 50.7 hours were devoted to professional activities. The surgeons also devoted a mean of 6.7 evening hours per week to professional activities for a mean net professional week of 57.4 hours. Comparisons with a population of previously studied community surgeons revealed that the prepaid group surgeons were able to produce a surgical output more than double that of the community surgeons while devoting only one and a half as much time to professional activities. Economies in the utilization of surgical manpower in the prepaid group appear to stem from: 1) restriction of practice setting to a single geographic location, 2) restriction of patients to surgical patients, 3) reduced surgeon waiting time in the office, and 4) the utilization of paraprofessional personnel for selected operative assisting. These economies were achieved while the prepaid group surgeons were observed to average more time per patient visit both on rounds and in the office than the community surgeons.     

The rare problem of late recurrence in neuroblastoma

Two-year disease-free survival is considered highly predictive of therapeutic success with neuroblastoma and death from neuroblastoma greater than 5 years after diagnosis is a rare event. We report of an unusual case of death from neuroblastoma 20 years after diagnosis; a literature review and discussion of this rare phenomenon of late recurrence is also included. Five additional cases of late recurrence, defined as greater than 5 years after diagnosis, were found in the literature with adequate detail to be reviewed. Advanced disease was present at diagnosis in five of six cases; three of six had disseminated disease. No age or sex differences were noted. A peculiar tencency for recurrence during the teenage years, preceded by a long disease-free interval, was also present in all cases, perhaps a reflection of maturational alterations in the immune system or hormonal changes that previously had suppressed extensive disease. This phenomenon of late recurrence in neuroblastoma, albeit rare, adds another facet to the clinical behavior of an enigmatic and therapeutically unyielding childhood tumor.     

The use of tampons for identifying asymptomatic N. gonorrhoeae infections

Female contacts of males with gonococcal urethritis were screened for asymptomatic infection using self-inserted tampons. Results of cultures were compared with specimens collected with cervical swabs during a pelvic examination. The sequence of collection of specimens was randomized, and specimens were promptly incubated. Among 297 patients, 40.4% had positive cervical specimens and 35.4% had positive tampon specimens. A difference in rates of recovery by method of collection was 5.0% +/- 1.7%. A better correlation in results was noted among patients using oral contraceptives and among patients whose tampon specimen was collected after a pelvic examination. A relatively small difference in results by method of collection suggests that tampons may serve as an inexpensive screening device for sexually active women, especially in settings where pelvic examinations are not routinely performed, but where immediate processing of specimens is possible.     

Identification and treatment of leukocytospermia in couples with unexplained infertility

OBJECTIVE: To evaluate whether identifying men with leukocytospermia in couples with unexplained infertility and treating them with antibiotics improves pregnancy rates. STUDY DESIGN: A prospective, cohort study of men with and without leukocytospermia was identified on a smear of semen using Bryan-Leishman stain. Cumulative six-month pregnancy rates were determined for members of the leukocytospermic group who responded to treatment with resolution of their leukocytospermia on a semen smear, those who failed to respond to treatment, those not treated and those without leukocytospermia. RESULTS: Thirty-six of 53 men with leukocytospermia responded to antibiotic treatment, and 19 women in these 36 couples (53%) became pregnant within the six-month follow-up period. Only 7 of 17 (6%) of those who failed to respond to treatment had their partner become pregnant (P < .001). Partners of men with leukocytospermia and no treatment had a 6% pregnancy rate, and the women in 13% (5/42) of couples without leukocytospermia became pregnant (P < .001). CONCLUSION: Leukocytospermia exists in a significant number of males with unexplained infertility and normal semen analyses. Identifying and successfully treating such men results in a significant improvement in pregnancy rates. These men may be a subgroup with male infertility that can be identified and treated.
