Initial experience with the Rosen incontinence device.

During a 25-month period, beginning in May 1977, 19 patients had Rosen incontinence devices implanted. During the 9 to 34 months of followup 26 additional operations were required for urethral compression balloon leakage, urethral compression balloon aneurysm, tubing kinks, reservoir malfunction and urethral erosion. Currently, 7 devices are in place, 6 of which are functioning and 3 of which have aneurysms of the urethral compression balloon. The 6-month failure rate of the first device was 44 per cent. During the 247 months that the devices were in place the patients were dry for 89 months, and required pad protection for 118 months and condom or an external urethral clamp for 40 months.

Prevalence and correlates of AIDS-risk behaviors among urban minority high school students.

BACKGROUND: To guide the development of an AIDS prevention program for urban minority high school students, the authors investigated the prevalence of AIDS-risk behaviors, and the relative explanatory power of demographic, contextual, and cognitive correlates of these behaviors, among black and Hispanic students in three New York City public high schools. METHODS: A survey was administered to a randomly selected sample of classrooms in the 9th through 12th grades of three public academic high schools in a New York City borough. Survey participants (n = 926) were 59% black and 34% Hispanic; the mean age was 16.4 (sd 1.4) years. RESULTS: Two-thirds of students reported having had sexual intercourse. Of the more than one-half of students who reported past-year intercourse, three-quarters had never or had inconsistently used condoms, one-third had multiple intercourse partners, one-tenth had a sexually transmitted disease, and one-twentieth had intercourse with a high-risk partner. Demographic (i.e., age, race/ethnicity) and contextual (i.e., academic failure, substance use, adverse life circumstances, cues to prevention) factors were most strongly associated with involvement in AIDS-risk behaviors; in contrast, cognitive factors (i.e., knowledge and beliefs about AIDS and AIDS-preventive actions) had little explanatory power. CONCLUSIONS: Addressing demographic and contextual risk factors for involvement in AIDS-related behaviors may prove to be a more powerful AIDS-prevention strategy among adolescents than simply teaching facts about AIDS and fostering prevention-related beliefs.

The costs of contraception.

The cost of contraception is one factor that affects the choice of a birth control method. An analysis of the first-year costs for the various methods, based on fees charged by private physicians and supplies purchased at drugstores, shows that the cost can be considerable and that there are large differences in cost between methods. Prescription contraceptives--the pill, IUD and diaphragm--are by far the most expensive of the reversible methods because they require medical supervision, but supplies alone are also more expensive for prescription methods than for nonprescription methods. First-year cost is highest for the pill-$172, compared with $160 for the diaphragm and $131 for the IUD. The mean of $154 for these three prescription methods is almost four times the mean first-year cost of $40 for condoms and foam. Sterilization necessitates the largest initial expenditure, and the cost of tubal ligation-$1,180-is almost five times the cost of vasectomy-$241. However, sterilization represents a one-time cost, while the other methods involve recurring expenses that may add up to more than the cost of sterilization over time. The methods that are associated with the lowest failure rates-sterilization, the pill and the IUD-are among the most expensive. To offset the costs of contraception, 4.6 million American women obtained low-cost care from subsidized family planning clinics in 1980.

Sex in Australia: contraceptive practices among a representative sample of women.

OBJECTIVES: To document the use of contraception by a representative sample of Australian women aged 16-59 years. METHOD: Between mid-2001 and mid-2002, computer-assisted telephone interviews were completed by 9,134 women aged 16-59 years from all States and Territories selected by modified random-digit dialling of households (response rate 77.6%). Respondents were asked about contraceptive methods used in their current regular relationship(s) and during recent sexual encounters, or in general, or their reasons for non-use. Responses were allocated to 14 categories. RESULTS: 70.8% of respondents were using a method of contraception, over 95% of those apparently at risk of pregnancy. Most common reasons for non-use were not having intercourse (41.6%) and being past menopause (21.6%). Among those apparently at risk of unplanned pregnancy (i.e. who were heterosexually active and fertile but not pregnant or trying to become pregnant; 13.0% of non-users), the most common reasons for non-use were experience of side-effects or contra-indications (23.0%), leaving it to chance (20.2%), forgetting/not caring (18.9%), breast feeding (16.5%) and believing it unnatural/unhealthy (13.7%). No women cited religious objections or lack of access to services. The most used methods were oral contraceptives (33.6% of users), tubal ligation/hysterectomy (22.5%), condom (21.4%) and vasectomy of partner (19.3%). Tubal ligation rates were higher and condom use lower in regional and remote areas. CONCLUSION: Given the high levels of use and knowledge and lack of evidence of unmet service need, most unplanned pregnancies in Australian adults are likely to be attributable to method failure or inconsistent use.

Challenges in the conduct of vaginal microbicide effectiveness trials in the developing world.

Conducting a phase III trial of a vaginal microbicide in a developing country poses several important and complex ethical challenges. As part of a process to bridge the gap between ethical theory and practice, we share our experiences in performing a phase III trial of Col 1492 (Advantage S) among female sex workers at four sites world-wide; Durban, Abidjan, Cotonou and Hat Yai. The ethical challenges included: (i) difficulties in obtaining informed consent. Participants were unable to grasp the concepts of a clinical trial for several weeks to months. In Cotonou, 30% of the women did not know the gel was tested for HIV prevention. Only 25% understood what a placebo was. In Durban, 70% of the women did not fully understand the study after 3 months; (ii) in sustaining the use of known HIV prevention strategies. Participants at the Durban site had difficulty in sustaining condom use due to financial and client preferences. Sex without condoms was worth more ($20) than sex with condoms ($10); (iii) in maintaining the confidentiality of the subject's HIV status. Novel approaches such as role plays and emphasis on other exclusion criteria were needed to maintain the confidentiality of women not included in the trial due to their HIV status; (iv) in providing care and support to the subjects who became infected with HIV during the trial. Women could only be offered routine sexually transmitted disease treatment and counselling. Anti-retrovirals were not offered. The successes and failures of the solutions attempted are described.

Adherence to antiretroviral therapy and its association with sexual behavior in a national sample of women with human immunodeficiency virus.

To delineate the relationship between adherence to human immunodeficiency virus (HIV) therapy and sexual behavior among HIV type 1-infected women in the United States, data were collected from October 1998 through March 1999 from 766 HIV-positive women on adherence to therapy, risk behavior, and disease markers. Adherence rates of >/=95% were reported by 66% of the patients. In multivariate analyses, patients with lower rates of adherence tended to be younger (odds ratio [OR], 1.69), to be active drug users (OR, 2.27), to have detectable virus load levels (OR, 2.00), and to have a lower quality of life (OR, 1.20). Among sexually active women, lower adherence rates were associated with an increased risk for inconsistent condom use (adjusted OR, 2.17). Although counseling regarding sexual behavior and adherence to treatment regimens are often addressed separately, our data highlight the importance of discussing these factors in relation to one another, particularly with regard to patients experiencing virologic failure.

HIV/AIDS: sex, abstinence, and behaviour change.

HIV prevention has focused on reducing the chances of transmission of the pathogen via sexual transmission. We argue that current pressures to persuade people that "abstinence" is a reasonable programme goal are based on misapprehension as to the balance between environmental and contextual factors and individual choices in determining why and how people have sex. Continuing insistence on the part of major prevention programme funders that changing behaviour alone--rather than changing its context--is the main problem will result in poor policy choices. It is particularly important to get these choices right at a time when increased amounts of money are becoming available for engagement with the HIV/AIDS epidemic. Failure to take account of this problem may have results beyond the field of HIV prevention.

Prevalence and determinants of contraceptive practice in a defined Nigerian population.

This study investigates the prevalence and determinants of contraceptive practice in Ile-Ife, Nigeria. A prospective study of 500 rural women in the reproductive age group was conducted between April to June 1999 in the Igboya health district of Ife central local government area of Osun State. A comprehensive contraceptive promotion and distribution had been carried out in this area by the University Teaching Hospital, the State Ministry of Health and many non-governmental organisations in the past 10 years. It is therefore expected that the contraceptive awareness and use in this environment would be high. Unfortunately, although all the respondents (100%) were aware of contraception and 78% were sexually active, only 18.8% used contraception. A majority of the non-users gave no reasons for failure to use contraception. Among reasons given by others include fear of side effects, no need for contraception, not married, religion, need for more children and student status. The most common contraceptive method among users was intrauterine contraceptive device followed by pills, condoms and injectable contraceptives. Factors which were significantly associated with utilisation of contraception were availability of family planning services, parity, knowledge of contraception and child spacing (P < 0.05). Religion, literacy level, attitudes of family planning providers and distance to family planning services were not found to be significant (P > 0.05). Recommendations that will improve wide contraceptive usage are preferred.

The effect of number of exposures on the risk of heterosexual HIV transmission.

Several studies of the heterosexual transmission of human immunodeficiency virus have reported no association between transmission and number of exposures. In contrast, this study showed that for a susceptible sex partner, the number of exposures to an infected index case is indeed associated with transmission, but in a nonlinear fashion. Factors that can dilute an association between transmission and number of exposures include measurement error in calculating number of exposures, use of inappropriate statistical models, and failure to account for variations in transmission rates. For example, the practice of anal intercourse and the experience of bleeding during intercourse increase the likelihood of transmission. We also observed that transmission occurred with fewer exposures among couples who did not use condoms compared with couples who did. The number of exposures also affects the independent association between other risk factors and transmission and thus should be considered when analyzing other sources of risk.

Management of bladder dysfunction in multiple sclerosis.

Sixty-seven consecutive patients participated in a prospective urodynamic study of the diagnosis and treatment of urinary bladder symptoms in multiple sclerosis. The etiology of symptoms was classified as either failure to store urine (30%), failure to empty the bladder (18%), or a combination of the two (50%). Treatment was individualized on the basis of the underlying pathophysiology and consisted of intermittent self-catheterization (21%), none (20%), surgical (12%), drugs (9%), voiding maneuvers (6%), and external condom drainage (6%). In 18 patients (27%), lesser forms of treatment were unsuccessful, and indwelling vesical catheters were required. Symptoms correlated poorly with urodynamic findings, and treatment based on symptoms alone would have been ineffective in over half the patients.

Intermittent catheterization failure and an approach to bladder rehabilitation in spinal cord injury patients.

Forty-six patients with spinal injury with dysfunctional neurogenic bladder were analyzed. Fourteen patients on prolonged intermittent catheterization from 12 weeks to more than 1 year did not develop a balanced bladder, 14 patients had indwelling catheters after intermittent catheterization failed elsewhere and 18 patients on external condom drainage presented with difficult voiding and repeated infections. There were 16 quadriplegics (1 incomplete), 21 paraplegics, and 9 incomplete cauda equina lesions. Urologic and urodynamic evaluation revealed detrusor-sphincter dyssynergia in 15 patients, vesicoureteral reflux in 10, and areflexic bladders in 11. Five patients over the age of 55 years showed slight enlargement of the prostrate. Some degree of bladder neck fibrosis was suspected in 26. More than one urologic pathology was encountered in the same patient. Transurethral sphincterotomy was carried out in 38 patients and only one transurethral resection of the prostrate (TURP) in an incomplete quadriplegic patient. In seven patients with no obvious urodynamic abnormality, a balanced bladder was achieved with intermittent catheterization; however, one of these patients needed a transurethral sphincterotomy on subsequent admission. A balanced bladder was achieved in all patients except the one with incomplete quadriplegia. Significant improvement in vesicoureteral reflux and relief from autonomic dysreflexic symptoms were recorded in all patients.

Peri-abortion contraceptive care: can we reduce the incidence of repeat abortions?

INTRODUCTION: It is of great importance for repeat unwanted pregnancies to be prevented rather than aborted. We therefore sought to: determine the reasons for contraceptive failure in women seeking repeat abortions; audit the peri-abortion contraception services offered at our hospital, and make recommendations regarding peri-abortion contraception services based on the above findings. METHOD: A self-administered questionnaire was used to determine the contraceptive practices and details of peri-abortion contraceptive counselling received by 50 women undergoing a repeat, and 83 women undergoing a first-time, abortion. RESULTS: Ninety-eight percent of women undergoing a repeat abortion reported using contraception at the time of conception, as compared to 83% of women undergoing a first-time abortion. This difference was significant (p = 0.009). Condoms were the main method used by 57% of women undergoing a repeat and 70% of women undergoing a first-time abortion. The oral contraceptive pill (OCP), including both combined oral contraceptive and progestogen-only pill, was the main method used by 37% of women undergoing a repeat and 25% undergoing a first-time abortion. Both these methods were found to be ineffective because of user-dependent failures. All women received peri-abortion contraceptive counselling, but the perceived contents varied. Follow-up contraceptive appointments were made in less than half of women. Although most women chose an optimal contraceptive method as a result of the counselling, compliance with the chosen method in women undergoing repeat abortions was poor. CONCLUSIONS: Standards of audit were met with regards to receipt of contraceptive counselling and agreeing a contraceptive method before discharge. The content of this counselling needs to be improved. The ineffectiveness of the OCP and barrier methods of contraception needs to be highlighted during counselling. Adequate follow-up arrangements need to be provided to ensure compliance of the chosen method of contraception.

Contraception before and after termination of pregnancy: can we do it better?

AIM: To compare contraceptive use pre- and post-therapeutic abortion in 1995, 1999 and 2002 in a New Zealand clinic. METHODS: Retrospective, consecutive case review of women presenting for therapeutic abortion. Anonymous data included demographic details, contraception used at conception, and post-termination contraception. RESULTS: Pre-conception contraceptive use is significantly declining, with post-termination condom choice increasing. This is predominantly due to increasing numbers of Asian women presenting for abortion. In 2002, 97% of Asian women used no contraception or only condoms pre-conception, and 62% chose condoms or abstinence post-termination. Oral contraceptives are used significantly less by Asian than European women both pre-termination (p = 0.0002) and post-termination (p = 0.00001). Other ethnic groups showed little change in contraceptive use over the study periods. CONCLUSIONS: It is speculated that ethnic Chinese women lack adequate contraceptive education, demonstrate distrust of non-barrier methods, believe men should provide the prophylactic, and mistakenly believe contraception unnecessary for the first week following menstruation. Abortion may be used for family planning rather than as back up for contraceptive failure. Young Chinese arriving in New Zealand require immediate sexual health education including accurate contraceptive information. Liaison between primary healthcare sectors and policy makers of immigration and other services assisting overseas students is recommended to provide culturally appropriate education.

A scenario study of oral contraceptive use in Japan. Toward fewer unintended pregnancies.

A scenario study was conducted to assess the extent to which the unintended pregnancy rate in Japan, where oral contraceptives (OC) have not been legalized for family planning purposes and couples rely mainly on condoms, might change if more women were to use OC. Because current rates of unintended pregnancy and abortion in Japan are not known, data provided by the 1994 Japanese National Survey on Family Planning were used to construct scenarios for national contraceptive use. Annual failure rates of contraceptive methods and nonuse were applied to the contraceptive use scenarios, to obtain estimates of the annual number of contraceptive failure-related pregnancies. Subsequently, contraceptive practice situations assuming higher OC use rates were defined, and the associated change in the number of contraceptive failure-related pregnancies was estimated for each situation. It emerged that OC use rates of 15% decreased the expected number of unintended pregnancies by 13%-17%, whereas use rates of 25% resulted in decreases of 22%-29% and use rates of 50% in decreases of 45%-58%. The findings were reasonably robust to variation in the assumptions that were made. In conclusion, each theoretical percentage increase in the OC use rate in Japan was found to lead to a roughly equivalent percentage decrease in the number of unintended pregnancies.

Catheters and catheter care.

For patients with incontinence who cannot be managed by other means, external or internal urine collecting devices may be useful. Condom catheters have been used for men, but analogous external collection devices for women are not widely available. Long-term urethral catheterization causes a dynamic polymicrobial bacteriuria that may be complicated by fever, catheter obstruction, bacteremia, acute pyelonephritis, urinary stones, chronic tubulointerstitial nephritis, renal failure, or death. Understanding these complications may lead to better decisions for patients and perhaps to new management options for incontinence.

A clinical experience with dantrolene sodium for external urinary sphincter hypertonicity in spinal cord injured patients.

Significant bladder residual urine is secondary to pelvic floor skeletal muscle hypertonicity in some spinal cord injury patients with suprasacral or mixed lesions. Fifteen patients with residual urine volumes greater than 150 cc were treated with dantrolene sodium because of its ability to decrease skeletal muscle contractibility. All of the patients had urethral closure pressures greater than 100 cm. water. Of the 15 patients 8 benefited from dantrolene sodium therapy and were maintained on external condom urinary drainage. Five of these 8 patients required up to 600 mg. dantrolene sodium daily to affect this result. The residual urine volume decreased to less than 100 cc and the post-therapy decrease in urethral pressure averaged 77 cm. water (49 per cent). The patients in the failure group (residual urine greater than 150 cc) had an average decrease in urethral pressure of 21 cm. water (16 per cent). Detrusor hyporeflexia possibly contributed to the failure rate. In summary, dantrolene sodium seems to be beneficial in some patients with external urinary sphincter hypertonicity. However, it will not supplant external sphincterotomy in the more complete male spinal cord injury patient in whom reflex incontinence is of minimal concern. Dantrolene sodium could be an ideal treatment of patients with incomplete neurologic lesions in whom continence might be preserved. The drug will have to be effective at low doses to obviate the major side effect of over-all muscle weakness.
