Prevalence and risk factors for sexually transmitted infections in a high-risk occupational group: the case of fishermen along Lake Victoria in Kisumu, Kenya.

The aim of this study was to assess prevalence and risk factors for sexually transmitted infections (STIs) among fishermen along Lake Victoria, Kenya. This cross-sectional study surveyed 250 fishermen from beaches in Kisumu District using proportional-to-size sampling based on the number of registered boats per beach. Participants provided demographic and sexual behaviour information, blood for HIV-1 herpes simplex virus type 2 (HSV-2) and syphilis serological tests urine for transcription-mediated amplification assays for Neisseria gonorrhoeae and Chlamydia trachomatis and penile and scrotal swabs for human papillomavirus (HPV) DNA assay. Consistent condom use with the three most recent sexual partners was reported by 30%; 38% reported concurrent sexual partnerships and 65% reported ever having transactional sex. HIV seroprevalence was 26%, HSV-2 seroprevalence by Western blot assay was 58% and 9.5% were rapid plasma reagin and Treponema pallidum particle agglutination assay positive. Genital HPV DNA of any type was detected in 57.2% with 74% of these having two or more HPV types. C. trachomatis and N. gonorrhoeae were detected in 3.2% and 1.2% respectively. Risk factors for syphilis seropositivity included working on multiple beaches during the past year (adjusted odds ratio [AOR] 3.81; 95% confidence interval [CI] 1.29-11.28). HPV infection was associated with owning a radio which is a marker for higher socioeconomic status (AOR 6.33; 95% CI 2.94-7.14) and reporting transactional sex with the most recent sexual partner (AOR 3.03; 95% CI 1.23-7.69). In conclusion, 90% of fishermen had evidence of one or more STIs. This exceptionally high-risk occupational group represents a high priority for preventive interventions.

[Avulsion of the penile skin: a conservative approach]. / Avulsione della cute peniena: un approccio conservativo.

INTRODUCTION: Skin avulsion of male genital is a rare urological emergency. Although not life-threatening such lesions are both physically and psychologically traumatic. If poorly managed in the acute setting, these injuries may result in long-term problems or permanent disabilities. METHODS: A 58 year-old male patient was admitted to the Emergency Department of our hospital with a traumatic injury of the penis, caused by a bike trauma. At the inspection, a rather complete degloving of penis and a tear in scrotal skin with no involvement of testes were observed. The skin was completely detached, out of the penis, but for a small flap at the peno-scrotal angle. After a careful cleaning, the penis was covered again with the skin attached to peno-scrotal angle through multiple circumferential sutures. RESULTS: A complete cover of the defects was obtained with one-step surgery. The patient was treated with broad spectrum of antibiotics for 1 month. No infections occurred. The patient was discharged from hospital after 5 days. After 3 months from trauma, the patient is able to achieve sexual intercourse, with normal erectile function, no painful erections and no penile recurvatum. CONCLUSIONS: Traumatic skin avulsion of penis is a rare condition; the best aesthetic and functional results depends on the choice of the proper treatment. Conservative approach in selected cases can provide good results both aesthetically and functionally.

[Transvaginal repair of neobladder vaginal fistula]. / Riparazione trans-vaginale di fistola neovescico-vaginale.

INTRODUCTION: Neobladder vaginal fistula is a known complication after cystectomy and orthotopic neobladder in women. The exact incidence is still unknown, even if in some of the largest series is reported in about 5% of female patients. We present our personal experience with a case of neobladder vaginal fistula. METHODS: A fifty-year old woman affected by T2G3 bladder cancer underwent radical cystectomy and orthotopic neobladder in December 2007. Definitive pathological examination revealed pT3aN0G3 urothelial cancer with squamous aspects. Two cycles of neoadjuvant chemotherapy were administered before cystectomy. Three weeks after cystectomy, a retrograde cystography revealed a fistula between vagina and neobladder. At first, the patient was treated conservatively, keeping the urethral catheter for two months. Cystographies, repeated every month, recorded a reduction in size of the fistula but not the complete closure. A surgical correction was planned. Preoperative cystoscopy showed the neobladder opening of the fistula on the posterior wall. Then a transvaginal approach with fistula excision and a two layer cross suture were performed. RESULTS: At the cystography performed 1 month after surgical repair no fistula was detected, and the patient was completely dry. At 3 months follow-up the patient was completely dry. CONCLUSION: The development of a neobladder-vaginal fistula is a significant, even if infrequent, complication after cystectomy. In our case, we performed a transvaginal approach without tissue interposition, with good results. Such procedure is easy and effective and, in our opinion, can be tempted as first line surgical treatment.

[Retroperitoneoscopic nephropexy]. / Nefropessi retroperitoneoscopica.

INTRODUCTION: Nephroptosis has been defined as renal descent of 5 or more cm on orthostasis. This disease is more frequent in young and slim women. The patient complains pain in upright position,that regress lying down. The therapy consists of surgical treatment. We report the case of a woman treated with retroperitoneoscopic nephropexy. METHODS: We present the case of a 25-years old woman, affected by lumbar pain in upright position for about 1 year. Ultrasound scan of the abdomen and RX-KUB did not show hydronephrosis nor stones. Both an orthopedic examination and a spinal MRI excluded bone or muscular diseases. Intravenous pyelography and diuretic isotope renography in upright position revealed a renal descent of more than 5 cm, without obstruction of upper urinary tract. The patient underwent a renal color doppler imaging, that showed reduction of right kidney resistive index in upright position. The patient underwent a right retroperitoneoscopic nephropexy. After complete dissection of the perirenal fat from the kidney, three nonabsorbable sutures were placed between the posterior renal capsule and the psoas muscle. RESULTS: No blood loss nor peri-operative complications have been observed. One month after the procedure, the patient did not complain any pain. Renal color doppler, performed one month after the nephropexy, showed a normalization of resistive index. CONCLUSIONS: Symptomatic nephroptosis is a disease that has been questioned in the past. Nowadays, the modern imaging and functional examination available allow to identify the "true"cases of symptomatic nephroptosis. The treatment with retroperitoneoscopic nephropexy is an easy and effective procedure.

Utility of the Determine Syphilis TP rapid test in commercial sex venues in Peru.

OBJECTIVES: This study sought to evaluate the utility of the Determine Syphilis TP test performed in Peruvian commercial sex venues for the detection of active syphilis; and determine the feasibility of integrating rapid syphilis testing for female sex workers (FSW) into existing health outreach services. METHODS: We tested 3586 female sex workers for syphilis by Determine in the field using whole blood fingerstick, and by rapid plasma reagin (RPR) and Treponema pallidum haemagglutination assay (TPHA) in a central laboratory in Lima using sera. RESULTS: 97.4% of the FSW offered rapid syphilis testing participated; and among those who tested positive, 87% visited the local health centre for treatment. More than twice as many specimens were RPR reactive using serum in Lima (5.7%) than tested positive by whole blood Determine in the field (2.8%), and although most were confirmed by TPHA, only a small proportion (0.7%) were RPR reactive at >or=1:8 dilutions, and likely indicating active syphilis. Sensitivity, specificity and positive predictive value of the Determine Syphilis TP test in whole blood when compared to serum RPR reactivity at any dilution confirmed by TPHA as the gold standard were 39.3%, 99.2% and 71.4%, respectively. Sensitivity improved to 64.0% when using serum RPR >or=1:8 confirmed by TPHA. Invalid tests were rare (0.3%). CONCLUSIONS: Rapid syphilis testing in sex work venues proved feasible, but Determine using whole blood obtained by fingerstick was substantially less sensitive than reported in previous laboratory-based studies using serum. Although easy to perform in outreach venues, the utility of this rapid syphilis test was relatively low in settings where a large proportion of the targeted population has been previously tested and treated.
