INTRODUCTION: We examined male circumcision outcomes among young adults in an African setting. MATERIALS AND METHODS: Participants were healthy, sexually active, uncircumcised, HIV-seronegative males aged 18-24 years. The main outcomes measured included complications, healing, satisfaction and resumption of activities. RESULTS: Of 1,475 procedures, 26 (1.8%) were associated with 27 adverse events, most commonly wound disruption/delayed healing (0.6%), wound infection (0.4%), and bleeding (0.3%). Adverse events per clinician averaged 3.8 and 2.1% for procedures 1-100 and 101-200, respectively, and <1% for procedures 201-300, 301-400 and >400, respectively (p < 0.001). Participants resumed normal general activities after a median of 1 postoperative day and 93% with regular employment resumed working within 1 week. After 30 days, 99% of participants reported being very satisfied. After 90 days, 65% reported having had sex, 45% reported that their partners had expressed an opinion, 92% of whom were very satisfied with the outcome. CONCLUSIONS: Safe and acceptable adult male circumcision services can be delivered in developing country settings.

Introduction. Male circumcision is being promoted for HIV prevention in high-risk heterosexual populations. However, there is a concern that circumcision may impair sexual function. Aim. To assess adult male circumcision's effect on men's sexual function and pleasure. Methods. Participants in a controlled trial of circumcision to reduce HIV incidence in Kisumu, Kenya were uncircumcised, HIV negative, sexually active men, aged 18-24 years, with a hemoglobin >/=9.0 mmol/L. Exclusion criteria included foreskin covering less than half the glans, a condition that might unduly increase surgical risks, or a medical indication for circumcision. Participants were randomized 1:1 to either immediate circumcision or delayed circumcision after 2 years (control group). Detailed evaluations occurred at 1, 3, 6, 12, 18, and 24 months. Main Outcome Measures.(i) Sexual function between circumcised and uncircumcised men; and (ii) sexual satisfaction and pleasure over time following circumcision. Results. Between February 2002 and September 2005, 2,784 participants were randomized, including the 100 excluded from this analysis because they crossed over, were not circumcised within 30 days of randomization, did not complete baseline interviews, or were outside the age range. For the circumcision and control groups, respectively, rates of any reported sexual dysfunction decreased from 23.6% and 25.9% at baseline to 6.2% and 5.8% at month 24. Changes over time were not associated with circumcision status. Compared to before they were circumcised, 64.0% of circumcised men reported their penis was "much more sensitive," and 54.5% rated their ease of reaching orgasm as "much more" at month 24. Conclusions. Adult male circumcision was not associated with sexual dysfunction. Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.

OBJECTIVE: To develop a standard procedure for male circumcision in a resource-poor medical setting and prospectively evaluate the outcome in a randomized, controlled trial with the incidence of human immunodeficiency virus (HIV) as the main outcome, as studies suggest that circumcision is associated with a lower incidence of HIV and other sexually transmitted infections in high-risk populations. SUBJECTS AND METHODS: Healthy, uncircumcised, HIV-seronegative men aged 18-24 years from Kisumu District, Kenya, were offered participation in a clinical trial using a standard circumcision procedure based on "usual" medical procedures in Western Kenya. The follow-up included visits at 3, 8 and 30 days after circumcision, with additional visits if necessary. Healing, satisfaction and resumption of activities were assessed at these visits and 3 months from randomization. RESULTS: Overall, 17 (3.5%) of the 479 circumcisions were associated with adverse events judged definitely, probably or possibly related to the procedure. The most common adverse events were wound infections (1.3%), bleeding (0.8%), and delayed wound healing or suture line disruption (0.8%). After 30 days, 99% of participants reported being very satisfied with the procedure; approximately 23% reported having had sex and 15% reported that their partners had expressed an opinion, all of whom were very satisfied with the outcome. About 96% of the men resumed normal general activities within the first week after the procedure. CONCLUSION: Safe and acceptable adult male circumcision services can be delivered in developing countries should male circumcision ultimately be advocated as a public-health measure.

Human papillomavirus (HPV) prevalence was estimated from 2,705 sexually active, uncircumcised, human immunodeficiency virus seronegative men aged 17-28 years in Kisumu, Kenya. HPV prevalence was 51.1%(95% confidence interval: 49.2 - 53.0%) in penile cells from the glans/coronal sulcus and/or shaft. HPV prevalence varied by anatomical site, with 46.5% positivity in the glans/coronal sulcus compared with 19.1% in the shaft (p<.0001). High-risk HPV was detected in 31.2% of glans and 12.3% of shaft samples (p<.0001). HPV16 was the most common type and 29.2% of men were infected with more than one HPV type. Risk factors for HPV infection included presence of C. trachomatis, N. gonorrhea, self-reported sexually transmitted infections, and less frequent bathing. Lifetime number of sexual partners and herpes simplex virus type-2 seropositivity were also marginally associated with HPV infection.(c) 2009 UICC.

Background. We examined the effect of male circumcision on the acquisition of 3 nonulcerative sexually transmitted infections (STIs). Methods. We evaluated the incidence of STI among men aged 18-24 years enrolled in a randomized trial of circumcision to prevent human immunodeficiency virus (HIV) infection in Kisumu, Kenya. The outcome was first incident nonulcerative STI during 2 years of follow-up. STIs examined were laboratory-detected Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis infection. Results. There were 342 incident infections among 2655 men followed up. The incidences of infection due to N. gonorrhoeae, C. trachomatis, and T. vaginalis were 3.48, 4.55, and 1.32 cases per 100 person-years, respectively. The combined incidence of N. gonorrhoeae and C. trachomatis infection was 7.26 cases per 100 person-years (95% confidence interval, 6.49-8.13 cases per 100 person-years). The incidences of these STIs, individually or combined, did not differ by circumcision status as a time-dependent variable or a fixed variable based on assignment. Risks for incident STIs in multivariate analysis included an STI at enrollment, multiple sex partners within <30 days, and sexual intercourse during menses in the previous 6 months; condom use was protective. Conclusions. Circumcision of men in this population did not reduce their risk of acquiring these nonulcerative STIs. Improved STI control will require more-effective STI management, including partner treatment and behavioral risk reduction counseling.

BACKGROUND: Three randomized controlled trials (RCTs) have confirmed that male circumcision (MC) significantly reduces acquisition of HIV-1 infection among men. The objective of this study was to perform a comprehensive, prospective evaluation of risk compensation, comparing circumcised versus uncircumcised controls in a sample of RCT participants. METHODS AND FINDINGS: Between March 2004 and September 2005, we systematically recruited men enrolled in a RCT of MC in Kenya. Detailed sexual histories were taken using a modified Timeline Followback approach at baseline, 6, and 12 months. Participants provided permission to obtain circumcision status and laboratory results from the RCT. We evaluated circumcised and uncircumcised men's sexual behavior using an 18-item risk propensity score and acquisition of incident infections of gonorrhea, chlamydia, and trichomoniasis. Of 1780 eligible RCT participants, 1319 enrolled (response rate = 74%). At the baseline RCT visit, men who enrolled in the sub-study reported the same sexual behaviors as men who did not. We found a significant reduction in sexual risk behavior among both circumcised and uncircumcised men from baseline to 6 (p<0.01) and 12 (p = 0.05) months post-enrollment. Longitudinal analyses indicated no statistically significant differences between sexual risk propensity scores or in incident infections of gonorrhea, chlamydia, and trichomoniasis between circumcised and uncircumcised men. These results are based on the most comprehensive analysis of risk compensation yet done. CONCLUSION: In the context of a RCT, circumcision did not result in increased HIV risk behavior. Continued monitoring and evaluation of risk compensation associated with circumcision is needed as evidence supporting its' efficacy is disseminated and MC is widely promoted for HIV prevention.

OBJECTIVES: This analysis sought to identify factors associated with herpes simplex virus type 2 (HSV-2) infection among men aged 18-24 in Kisumu, Kenya. METHODS: We analyzed baseline data from a randomized trial of male circumcision. Participants were interviewed for socio-demographic and behavioral risks. The outcome was HSV-2 by antibody status. Risk factors were considered singly and in combination through logistic regression models. RESULTS: Among 2,771 uncircumcised men, 766 (27.6%; 95% confidence interval [CI]: 26.0-29.3%) tested antibody positive for HSV-2. The median age at first sex was 16 years, and the median number of lifetime sexual partners was 4. HSV-2 seroprevalence increased from 19% among 18 year-olds to 43% among 24 year-olds (p<0.001). In multivariable analysis, statistically significant risks for infection were: increasing age (adjusted odds ratio [AOR] ranged from 1.22-2.58), being married or having a live-in female partner (AOR=1.80; 95% CI: 1.28-2.53), preferring "dry" sex (AOR=1.39; 95% CI: 1.14-1.69), reported penile cuts or abrasions during sex (AOR=1.58; 95% CI: 1.32 - 1.91), increasing lifetime sex partners (multiple response categories; AORs ranging 1.65-1.97), and non-student occupation (multiple response categories; AORs ranging 1.44-1.93). Risk decreased with reported condom used at last sex (AOR=0.82; 95% CI: 0.68-0.99). CONCLUSION: Primary prevention efforts should be initiated at an early age. The same behavioral interventions used currently for HIV prevention- abstinence, reducing number of sex partners, and increasing condom use- should be effective for HSV-2 prevention.

BACKGROUND: Male circumcision could provide substantial protection against acquisition of HIV-1 infection. Our aim was to determine whether male circumcision had a protective effect against HIV infection, and to assess safety and changes in sexual behaviour related to this intervention. METHODS: We did a randomised controlled trial of 2784 men aged 18-24 years in Kisumu, Kenya. Men were randomly assigned to an intervention group (circumcision; n=1391) or a control group (delayed circumcision, 1393), and assessed by HIV testing, medical examinations, and behavioural interviews during follow-ups at 1, 3, 6, 12, 18, and 24 months. HIV seroincidence was estimated in an intention-to-treat analysis. This trial is registered with ClinicalTrials.gov, with the number NCT00059371. FINDINGS: The trial was stopped early on December 12, 2006, after a third interim analysis reviewed by the data and safety monitoring board. The median length of follow-up was 24 months. Follow-up for HIV status was incomplete for 240 (8.6%) participants. 22 men in the intervention group and 47 in the control group had tested positive for HIV when the study was stopped. The 2-year HIV incidence was 2.1%(95% CI 1.2-3.0) in the circumcision group and 4.2%(3.0-5.4) in the control group (p=0.0065); the relative risk of HIV infection in circumcised men was 0.47 (0.28-0.78), which corresponds to a reduction in the risk of acquiring an HIV infection of 53%(22-72). Adjusting for non-adherence to treatment and excluding four men found to be seropositive at enrollment, the protective effect of circumcision was 60%(32-77). Adverse events related to the intervention (21 events in 1.5% of those circumcised) resolved quickly. No behavioural risk compensation after circumcision was observed. INTERPRETATION: Male circumcision significantly reduces the risk of HIV acquisition in young men in Africa. Where appropriate, voluntary, safe, and affordable circumcision services should be integrated with other HIV preventive interventions and provided as expeditiously as possible.

Numerous epidemiologic studies have found significant associations between lack of circumcision and HIV-1 acquisition in men. To our knowledge, this is the first study of human foreskin tissue that examines biologic mechanisms that increase susceptibility of uncircumcised African men to HIV-1. Foreskin specimens from 20 men with and 19 men with no history of sexually transmitted infections were examined for HIV-1 target cells. Most Langerhans cells were found in the epithelium; most CD4+ T cells and macrophages were in the submucosa. There were no differences in HIV-1 target cells between men with and those without history of sexually transmitted infections. However Langerhans cells and macrophages were more abundant in the group with a history of infection. The densities and positions of HIV-1 target cells in the foreskin tissue of these Kenyan men indicate that the inner mucosal surface of the human foreskin contains cells that make it highly susceptible to HIV infection.

OBJECTIVE:: To evaluate whether sexual intercourse soon after adult male circumcision affected HIV risk. DESIGN:: Combined analysis of data from African trials of men who were randomized to and underwent circumcision. METHODS:: We examined two associations: early sex (intercourse <42 days after circumcision) and HIV acquisition at 3 months for the Orange Farm and Kisumu trials and at 6 months for the Rakai and Kisumu trials and incomplete wound healing at 1 month and seroconversion at 3 and 6 months for the Kisumu trial and at 6 months for the Rakai trial. RESULTS:: Early sex was reported by 3.9% of participants in Kisumu, 5.4% in Rakai, and 22.5% in Orange Farm. HIV seroprevalence was 0.0% at 3 months and 1.9% at 6 months among 18-24-year-olds reporting early sex and 0.2% at 3 months and 0.6% at 6 months among those who did not report early sex. In pooled analyses, men reporting early sex did not have higher HIV infection risk at 3 or 6 months. In Kisumu, 16 (1.3%) men had incomplete wound healing at the 30-day visit. One (6.3%) of these seroconverted at 3 months compared with 2 (0.2%) of 1246 men with complete wound healing (P = 0.075). No association was observed between incomplete wound healing and seroconversion for Rakai participants. CONCLUSION:: Most men delayed intercourse after circumcision. Early sex after circumcision was not associated with HIV risk, although the study power was limited. Nevertheless, men should delay intercourse to limit the potential for increased HIV risk until complete wound healing.

BACKGROUND:: Limited data are available on whether sampling from the penile shaft or urethra increases detection of penile HPV infection in men beyond that found in the glans and coronal sulcus. METHODS:: Within a randomized clinical trial, a validation study of penile sampling was conducted in Kisumu, Kenya. Young men (18-24 years) were invited to provide penile exfoliated cells using prewetted Dacron swabs to determine the best site for HPV detection. beta-Globin gene PCR and HPV DNA type GP5+/6+ PCR status were ascertained from 3 anatomical sites. RESULTS:: A total of 98 young HIV-seronegative, uncircumcised men participated. Penile HPV prevalence varied by anatomical site: 50% in penile exfoliated cells from the glans, coronal sulcus, and inner foreskin tissue; 43% in the shaft and external foreskin tissue; and 18% in the urethra (P <0.0001). For each anatomical site, over 87% of samples were beta-globin positive. Beyond that found in the glans/coronal sulcus, urethral sampling resulted in no increase in HPV positivity and shaft sampling resulted in an additional 7.3% of overall HPV positivity. The prevalence of high-risk HPV positivity varied by anatomical site: 39% in glans/coronal sulcus, 31% in shaft, and 13% in the urethra (P <0.0001). HPV 16 was the most common type identified. DISCUSSION:: Penile HPV prevalence was approximately 50% among young men in Kisumu, Kenya. Urethral sampling for HPV detection in men added no sensitivity for HPV detection over that found from sampling the glans/coronal sulcus and penile shaft. These data will help inform studies on HPV transmission dynamics, and on the efficacy of HPV prophylactic vaccines on penile HPV carriage in men.

OBJECTIVE: Standardization of and training in adult male circumcision can significantly reduce its complication rate. Currently no such program exists for its standardization and training, making it difficult to guarantee the quality of male circumcision services. We therefore established a standardized surgical protocol for adult male circumcision in China using the Shang Ring, and applied it to a clinical study examining the performance of the Shang Ring in adult male circumcision. METHODS: A total of 328 adult men aged 18-58 (mean 27.8) years, 25 with phimosis and 303 with redundant prepuce, underwent circumcision with the Shang Ring, and evaluation of the operation time, pain scores (using the visual analog scale), postoperative complications, time for wound healing, and their satisfaction with the postoperative appearance. RESULTS: The operation time was 4.7 +/- 1.3 minutes. The pain scores were 0. 2 +/- 0.6 during the surgery, 1.6 +/- 1.0 twenty hours postoperatively, 1.7 +/- 1.1 twenty hours prior to the ring removal, and 2.7 +/- 1.4 during the ring removal. Complications included infection in 2 (0.6%), bleeding in 2 (0.6%), and wound dehiscence in 2 (0.6%) of the patients. None of the patients with wound dehiscence required postoperative suturing and all were managed conservatively instead. Sixteen of the patients (4.9%) experienced penile edema. The time for complete wound healing after circumcision was 20.3 +/- 6.7 days. The rate of the patients'satisfaction was 99.7%(327/328). CONCLUSION: The standard protocol of adult male circumcision with the Shang Ring has the advantages of short operation time, slight pain, low rate of complications, and high satisfaction and acceptance of the patients. Strict standardization of the surgical protocol can maximize its clinical advantages for adult male circumcision.

BACKGROUND: The Tara KLamp (TK) device has been claimed to enable circumcisions to be performed safely and easily in medical and non-medical environments. Published evaluation studies have been conducted among young children only. METHODS: Following a randomised controlled trial (RCT) on 3 274 participants on the impact of male circumcision on HIV transmission, 69 control group members participated in this male circumcision methods trial and were randomised to a forceps-guided (FG) group and a TK group, and circumcised. RESULTS: Of the 166 men asked to participate, 97 declined, most (94) refusing circumcision by the TK technique; 34 men were randomised to the FG group and 35 to the TK group, and 32 and 24 patients were circumcised by the FG and TK methods respectively, of whom 29 and 19 respectively attended the post-circumcision visit. All 12 adverse event sheets corresponded to the TK group (p<0.001) and circumcisions by the TK method. Less favourable outcomes were associated with the TK method, including any sign of an adverse event (37% v. 3%; p=0.004), delayed wound healing (21% v. 3%; p=0.004) and problems with penis appearance (31% v. 3%; p=0.001). Participants randomised to the TK method were significantly more likely to report bleeding (21% v. 0%; p=0.02), injury to the penis (21% v. 0%; p=0.02), infection (32% v. 0%; p=0.002), swelling (83%/ v. 0%; p<0.001), and problems with urinating (16% v. 0%; p=0.056). The mean score of self-estimated pain was 9.5 for participants circumcised by TK compared with 6.1 for other participants (adjusted p=0.003). CONCLUSION: This study provides compelling evidence that strongly cautions against use of the TK method on young adults.

The results of recent controlled trials documenting the protective effect of male circumcision on HIV infection in young adults pose significant challenges to a country like Israel. Circumcision is performed in close to 100% of new born males, mostly as a religious act in Judaism and Islam. Christian Israelis follow societal norms suggesting that circumcision contributes to better hygiene and cleanliness. Complications in infant circumcision in Israel are rare, despite the surgery being preformed most often by nonmedical circumcisers (a "Mohel") on the eighth day of birth. Reported complication rates are between 0.34% and 2%, with bleeding and infections being the most common. In the last 10 years and due to massive migration of Eastern Europeans into Israel, impressive experience was gained in Israel with adults seeking male circumcision for various reasons including: religious, societal pressure, sexual and economical. Over 21,800 adult male circumcisions have been monitored between 1998 and 2006 alone. Complication rates (mostly bleeding) were 1.75% on an average. This review matches the new data emerging from the African controlled trials with previous observational studies and the Jewish and Israeli experience. We present three challenges to policy makers in Israel:(a) the need to intensify education and information sharing on male circumcision and HIV/AIDS among healthcare workers;(b) developing an information campaign for non-circumcised migrants and adequate service to scale up on potential demand;(c) developing intensified educational campaigns for circumcised males so that they do not abandon other protective interventions (e.g. condoms) when needed for HIV prevention.

OBJECTIVES: To review and synthesize the literature in the following areas: the association of specific circulating 25(OH)D concentrations with bone health outcomes in children, women of reproductive age, postmenopausal women and elderly men; the effect of dietary intakes (foods fortified with vitamin D and/or vitamin D supplementation) and sun exposure on serum 25(OH)D; the effect of vitamin D on bone mineral density (BMD) and fracture or fall risk; and the identification of potential harms of vitamin D above current reference intakes. DATA SOURCES: MEDLINE(R)(1966-June Week 3 2006); Embase (2002-2006 Week 25); CINAHL (1982-June Week 4, 2006); AMED (1985 to June 2006); Biological Abstracts (1990-February 2005); and the Cochrane Central Register of Controlled Trials (2nd Quarter 2006). REVIEW METHODS: Two independent reviewers completed a multi-level process of screening the literature to identify eligible studies (title and abstract, followed by full text review, and categorization of study design per key question). To minimize bias, study design was limited to randomized controlled trials (RCTs) wherever possible. Study criteria for question one were broadened to include observational studies due to a paucity of available RCTs, and question four was restricted to systematic reviews to limit scope. Data were abstracted in duplicate and study quality assessed. Differences in opinion were resolved through consensus or adjudication. If clinically relevant and statistically feasible, meta-analyses of RCTs on vitamin D supplementation and bone health outcomes were conducted, with exploration of heterogeneity. When meta-analysis was not feasible, a qualitative systematic review of eligible studies was conducted. RESULTS: 167 studies met our eligibility criteria (112 RCTs, 19 prospective cohorts, 30 case-controls and six before-after studies). The largest body of evidence on vitamin D status and bone health was in older adults with a lack of studies in premenopausal women and infants, children and adolescents. The quality of RCTs was highest in the vitamin D efficacy trials for prevention of falls and/or fractures in older adults. There was fair evidence of an association between low circulating 25(OH)D concentrations and established rickets. However, the specific 25(OH)D concentrations associated with rickets is uncertain, given the lack of studies in populations with dietary calcium intakes similar to North American diets and the different methods used to determine 25(OH)D concentrations. There was inconsistent evidence of an association of circulating 25(OH)D with bone mineral content in infants, and fair evidence that serum 25(OH)D is inversely associated with serum PTH. In adolescents, there was fair evidence for an association between 25(OH)D levels and changes in BMD. There were very few studies in pregnant and lactating women, and insufficient evidence for an association between serum 25(OH)D and changes in BMD during lactation, and fair evidence of an inverse correlation with PTH. In older adults, there was fair evidence that serum 25(OH)D is inversely associated with falls, fair evidence for a positive association with BMD, and inconsistent evidence for an association with fractures. The imprecision of 25(OH)D assays may have contributed to the variable thresholds of 25(OH)D below which the risk of fractures, falls or bone loss was increased. There was good evidence that intakes from vitamin D-fortified foods (11 RCTs) consistently increased serum 25(OH)D in both young and older adults. Eight randomized trials of ultraviolet (UV)-B radiation (artificial and solar exposure) were small and heterogeneous with respect to determination of the exact UV-B dose and 25(OH)D assay but there was a positive effect on serum 25(OH)D concentrations. It was not possible to determine how 25(OH)D levels varied by ethnicity, sunscreen use or latitude. Seventy-four trials examined the effect of vitamin D(3) or D(2) on 25(OH)D concentrations. Most trials used vitamin D(3), and the majority enrolled older adults. In three trials, there was a greater response of serum 25(OH)D concentrations to vitamin D(3) compared to vitamin D(2), which may have been due to more rapid clearance of vitamin D(2) in addition to other mechanisms. Meta-analysis of 16 trials of vitamin D(3) was consistent with a dose-response effect on serum 25(OH)D when comparing daily doses of <400 IU to doses >/= 400 IU. An exploratory analysis of the heterogeneity demonstrated a significant positive association comparable to an increase of 1 - 2 nmol/L in serum 25(OH)D for every 100 additional units of vitamin D although heterogeneity remained after adjusting for dose. Vitamin D(3) in combination with calcium results in small increases in BMD compared to placebo in older adults although quantitative synthesis was limited due to variable treatment durations and BMD sites. The evidence for fracture reduction with vitamin D supplementation was inconsistent across 15 trials. The combined results of trials using vitamin D(3)(700 - 800 IU daily) with calcium (500 - 1,200 mg) was consistent with a benefit on fractures although in a subgroup analysis by setting, benefit was primarily in elderly institutionalized women (fair evidence from two trials). There was inconsistent evidence across 14 RCTs of a benefit on fall risk. However, a subgroup analysis showed a benefit of vitamin D in postmenopausal women, and in trials that used vitamin D(3) plus calcium. In addition, there was a reduction in fall risk with vitamin D when six trials that adequately ascertained falls were combined. Limitations of the fall and fracture trials included poor compliance with vitamin D supplementation, incomplete assessment of vitamin D status and large losses to follow-up. We did not find any systematic reviews that addressed the question on the level of sunlight exposure that is sufficient to maintain serum 25(OH)D concentrations but minimizes risk of melanoma and non-melanoma skin cancer. There is little evidence from existing trials that vitamin D above current reference intakes is harmful. In most trials, reports of hypercalcemia and hypercalciuria were not associated with clinically relevant events. The Women's Health Initiative study did report a small increase in kidney stones in postmenopausal women aged 50 to 79 years whose daily vitamin D(3) intake was 400 IU (the reference intake for 50 to 70 years, and below the reference intake for > 70 years) combined with 1000 mg calcium. The increase in renal stones corresponded to 5.7 events per 10,000 person-years of exposure. The women in this trial had higher calcium intakes than is seen in most post-menopausal women. CONCLUSIONS: The results highlight the need for additional high quality studies in infants, children, premenopausal women, and diverse racial or ethnic groups. There was fair evidence from studies of an association between circulating 25(OH)D concentrations with some bone health outcomes (established rickets, PTH, falls, BMD). However, the evidence for an association was inconsistent for other outcomes (e.g., BMC in infants and fractures in adults). It was difficult to define specific thresholds of circulating 25(OH)D for optimal bone health due to the imprecision of different 25(OH)D assays. Standard reference preparations are needed so that serum 25(OH)D can be accurately and reliably measured, and validated. In most trials, the effects of vitamin D and calcium could not be separated. Vitamin D(3)(>700 IU/day) with calcium supplementation compared to placebo has a small beneficial effect on BMD, and reduces the risk of fractures and falls although benefit may be confined to specific subgroups. Vitamin D intake above current dietary reference intakes was not reported to be associated with an increased risk of adverse events. However, most trials of higher doses of vitamin D were not adequately designed to assess long-term harms.

OBJECTIVE: To investigate the relationship between adult male circumcision and sexual satisfaction and function in men, as observational studies on the effect of adult male circumcision on sexual satisfaction show conflicting results. SUBJECTS AND METHODS: We investigated self-reported sexual satisfaction and function among men enrolled in a randomized trial of male circumcision for human immunodeficiency virus (HIV) prevention conducted in Rakai, Uganda. In all, 4456 sexually experienced HIV-negative males aged 15-49 years were enrolled; 2210 were randomized to receive immediate circumcision (intervention arm) and 2246 to circumcision delayed for 24 months (control arm). Men were followed up at 6, 12 and 24 months, and information on sexual desire, satisfaction and erectile dysfunction was collected. These variables were compared between the study arms and over time within the study arms, using chi-square or Fisher's exact tests. The trial registration number is NCT00425984. RESULTS: There were no differences between the study arms at enrollment and problems with sexual satisfaction and function were reported by <2% of participants in both study arms at all time points. At 6 months, no difficulty with penetration was reported by 98.6% of circumcised men and 99.4% of controls (P = 0.02), and no pain on intercourse was reported by 99.4% circumcised and 98.8% of uncircumcised men (P = 0.05). There were no differences between the study arms in penetration or dyspareunia at later visits. Sexual satisfaction increased from 98.0% at enrollment to 99.9% at 2 years among the controls (P < 0.001), but there was no trend in satisfaction among circumcised men (enrollment 98.5%, 2 years 98.4%, P = 0.8). CONCLUSION: Adult male circumcision does not adversely affect sexual satisfaction or clinically significant function in men.

OBJECTIVE:: To examine characteristics of circumcised and uncircumcised Latino and black men who have sex with men (MSM) in the United States and assess the association between circumcision and HIV infection. METHODS:: Using respondent-driven sampling, 1154 black MSM and 1091 Latino MSM were recruited from New York City, Philadelphia, and Los Angeles. A 45-minute computer-assisted interview and a rapid oral fluid HIV antibody test (OraSure Technologies, Bethlehem, PA) were administered to participants. RESULTS:: Circumcision prevalence was higher among black MSM than among Latino MSM (74% vs. 33%; P < 0.0001). Circumcised MSM in both racial/ethnic groups were more likely than uncircumcised MSM to be born in the United States or to have a US-born parent. Circumcision status was not associated with prevalent HIV infection among Latino MSM, black MSM, black bisexual men, or black or Latino men who reported being HIV-negative based on their last HIV test. Further, circumcision was not associated with a reduced likelihood of HIV infection among men who had engaged in unprotected insertive and not unprotected receptive anal sex. CONCLUSIONS:: In these cross-sectional data, there was no evidence that being circumcised was protective against HIV infection among black MSM or Latino MSM.

OBJECTIVE: To report physical and psychologic outcomes for young adult survivors of pediatric burns. DESIGN: Prospective, correlational study. SETTING: Acute and rehabilitation pediatric burn care facility. PARTICIPANTS: Eighty-three young adult survivors of pediatric burns, who were 18 to 28 years of age, with total body surface area (TBSA) burns of 30% or greater, and were at least 2 years postburn. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Physical outcomes were assessed by muscle strength tests, grip and pinch measurements, mobility levels, and self-care (activities of daily living) skills. Psychologic outcomes included behavioral problems, personality disorder, and incidence of psychiatric illness. An individually administered Structured Clinical Interview for Diagnosis, based on the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, for psychiatric diagnosis, was used to assess mental health, and behavioral problems were assessed with the Young Adult Self-Report. Participants reported educational achievement, employment status, state of transition from family of origin (home) to independent living, and pair bonding. The Short-Form 36-Item Health Survey and the Quality of Life Questionnaire were used to assess each participant's self-reported general health and quality of life. RESULTS: The majority of subjects had physical and psychologic outcomes that were within the normal range when compared with age-mates who had not experienced burns. The areas that were most likely to be impaired involved peripheral strength (wrist and grip). These deficits affected some self-care skills and correlated with TBSA. Standardized diagnostic interviews showed that greater than 50% of subjects qualified for a psychiatric diagnosis, with anxiety disorders as the most frequently occurring diagnosis. There were few significant correlations of the physical measurements or self-care skills with the burn size, psychologic problems, or social outcomes, and none appeared to be clinically important. CONCLUSIONS: Most of the people in this sample were functioning physically and psychosocially within normal limits as they reached adulthood. Although they appeared to function well as measured by standardized assessments, there were indications of private suffering that suggested they may not be functioning at an optimal level. The findings suggest that rehabilitation professionals could improve outcomes by including programs to develop overall muscle strength in severely burned children and by addressing concerns related to anxiety and other symptoms of psychologic distress.

BACKGROUND:: The role of homosexuality and anal sex practices in the African HIV -1 epidemic is not well described. We aimed to assess the risk factors for prevalent HIV-1 infection among men who have sex with men (MSM) to guide HIV-1 prevention efforts. METHODS:: Socio-behavioural characteristics, signs and symptoms of sexually transmitted diseases (STD), and serological evidence of HIV-1 were determined for 285 MSM at enrolment into a vaccine preparedness cohort study. We used multivariate logistic regression to assess risk factors for prevalent HIV-1 infection. RESULTS:: HIV-1 prevalence was 43.0%[49/114, 95% confidence interval (CI), 34-52%] for men who reported sex with men exclusively (MSME), and 12.3%(21/171, 95% CI, 7-17%) for men who reported sex with both men and women (MSMW). Eighty-six (75%) MSME and 69 (40%) MSMW reported recent receptive anal sex. Among 174 MSM sexually active in the last week, 44% reported no use of condoms with casual partners. In the previous 3 months, 210 MSM (74%) reported payment for sex, and most clients (93%) were local residents. Prevalent HIV-1 infection was associated with recent receptive anal sex [odds ratio (OR), 6.1; 95% CI, 2.4-16], exclusive sex with men (OR, 6.3; 95% CI, 2.3-17), and increasing age (OR, 1.1 per year; 95% CI, 1.04-1.12). Only four MSM reported injecting drug use. CONCLUSIONS:: The high prevalence of HIV-1 in Kenyan MSM is probably attributable to unprotected receptive anal sex. There is an urgent need for HIV-1 prevention programmes to deliver targeted risk-reduction interventions and STD services to MSM in Kenya.

OBJECTIVE: To evaluate the effectiveness of follow-up telephone interviews and questionnaires after tonsillectomy and adenoidectomy. DESIGN: Cohort study and retrospective review of the outcomes of patients whose follow-ups were conducted by telephone interview. Patients were contacted 2 to 4 weeks after surgery; responses were recorded on a standardized postoperative questionnaire. SETTING: Tertiary pediatric hospital. PATIENTS: A total of 2554 consecutive patients who had undergone tonsillectomy, adenoidectomy, or both procedures and completed a follow-up telephone interview during the period of January 8, 2000, to September 23, 2004. MAIN OUTCOME MEASURES: Time to return to normal diet and activities, postoperative complications, pain management, postoperative visits, and caregiver's evaluation of the follow-up telephone survey. RESULTS: A total of 2554 patient outcomes were reviewed. The mean patient age was 5.9 years. Follow-up contact occurred a mean of 24.1 days after surgery. Of the surgical procedures performed, there were 1957 adenotonsillectomies, 235 adenoidectomies, and 362 tonsillectomies. At the time of follow-up, 2.7% of the patients had undergone an additional surgical procedure to treat postoperative bleeding, 96.9% had resumed eating a normal diet, and 96.2% had resumed normal activities. Bleeding from the nose or mouth was reported to have occurred at some point during the recovery period in 12.8%. On a pain scale of 1 to 10, a mean pain peak of 6.7 was reported. For most patients, pain was highest on the second day after surgery. The percentage of patients who had temporary voice change was 62.7%, and 15.4% had a follow-up clinic visit. Regarding caregivers, 99.5% reported being given instructions for postoperative care, and 98.8% reported that they felt well prepared to care for their child at home. There were no adverse events reported from surgical intervention. CONCLUSIONS: Compared with our previous experience with scheduled postsurgical clinic follow-ups, telephone interviews and standardized postoperative questionnaires pose no additional risk to patients. Considerable cost reduction and patient convenience were realized with a reduction of patient visits.

INTRODUCTION: 2-Octyl cyanoacrylate (2-OCA; Dermabond) is a synthetic tissue adhesive that has proven utility in the closure of minor surgical incisions. Recently, we began using this adhesive for skin closure after circumcision and herein report our experience. TECHNICAL CONSIDERATIONS: A total of 267 patients (mean age 4 years) underwent circumcision (n = 208) or circumcision revision (n = 59) using 2-OCA for skin closure. The circumcision was performed using a sleeve technique in 219 patients and a Gomco clamp in 48. After meticulous hemostasis, the incision was cleansed, and the skin edges were aligned. Two thin layers of 2-OCA were applied to the incision and allowed to dry. Antibiotic ointment was then applied to the glans and penis. The technique was not used if poor skin edge apposition or bleeding was noted after circumcision. The skin closure time using 2-OCA averaged 3 minutes for the first 150 patients and less than 90 seconds for the last 120 patients, reflecting a learning curve associated with application. At a mean follow-up of 13 months (range 2 to 18), three postoperative complications had occurred. The cosmetic outcomes have been subjectively better than those with standard closure using interrupted 5-0 or 6-0 sutures, with no risk of suture tracks or sinuses. Parental satisfaction has been consistently great. CONCLUSIONS: Sutureless circumcision closure using 2-OCA is a safe, fast, and cosmetically appealing alternative to standard interrupted suture reapproximation. These advantages have made it our technique of choice. A direct economic and outcome comparison to sutured repairs is ongoing.
