Long-term followup of subclinical human papillomavirus infection treated with the carbon dioxide laser and intraurethral 5-fluorouracil: a treatment protocol

We evaluated 162 high risk male patients for the presence of subclinical anogenital human papillomavirus infection with magnified penile surface scanning. Infected patients were treated as outpatients with the carbon dioxide laser under local anesthesia. Of the patients 43 were followed for a mean of 8.7 months or 2.1 treatments after the initial treatment (range 3 to 30 months). A subset of 10 patients was followed for more than 20 months or 6.2 treatments. To date a 51% recurrence rate has been observed in the over-all population and a 50% recurrence rate was noted in the 20-month followup population. In a separate arm of this study a small number of patients (15) with deoxyribonucleic acid typed subclinical intraurethral disease plus subclinical skin lesions were treated with topical carbon dioxide laser therapy for the penile lesions and adjuvant intraurethral 5% 5-fluorouracil. Mean followup in the group was approximately 4 months. The addition of intraurethral therapy in this positive human papillomavirus reservoir group had no significant effect on the high rate of human papillomavirus recurrence.     

Infant and Neonatal Mortality for Primary Cesarean and Vaginal Births to Women with “No Indicated Risk,” United States, 1998–2001 Birth Cohorts

ABSTRACT: Background: The percentage of United States’ births delivered by cesarean section has increased rapidly in recent years, even for women considered to be at low risk for a cesarean section. The purpose of this paper is to examine infant and neonatal mortality risks associated with primary cesarean section compared with vaginal delivery for singleton full‐term (37–41 weeks’ gestation) women with no indicated medical risks or complications. Methods: National linked birth and infant death data for the 1998–2001 birth cohorts (5,762,037 live births and 11,897 infant deaths) were analyzed to assess the risk of infant and neonatal mortality for women with no indicated risk by method of delivery and cause of death. Multivariable logistic regression was used to model neonatal survival probabilities as a function of delivery method, and sociodemographic and medical risk factors. Results: Neonatal mortality rates were higher among infants delivered by cesarean section (1.77 per 1,000 live births) than for those delivered vaginally (0.62). The magnitude of this difference was reduced only moderately on statistical adjustment for demographic and medical factors, and when deaths due to congenital malformations and events with Apgar scores less than 4 were excluded. The cesarean/vaginal mortality differential was widespread, and not confined to a few causes of death. Conclusions: Understanding the causes of these differentials is important, given the rapid growth in the number of primary cesareans without a reported medical indication. (BIRTH 33:3 September 2006)
