[Epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas in Senegal]. / Profil épidémiologique, étiologique et évolutif des fistules vésico-vaginales au Sénégal.

AIM: To evaluate the epidemiological, etiological and evolutionary profile of vesico-vaginal fistulas (VVF) in university hospitals in Senegal. PATIENTS AND METHOD: This is a retrospective, descriptive, single-center study, collecting the records of patients followed for VVF between January 2014 and December 2019 at the Urology and Andrology Department of the Centre hospitalier universitaire Aristide Le Dantec, Dakar, Senegal. The following parameters were studied: age, geographical origin, parity, and etiology of VVF. To assess the evolution of the epidemiological and etiological profile of VVF, we compared our results with those of series published by our structure. RESULTS: Forty-five (45) VVFs were identified over a period of 6 years. This represents an annual average of 7.5 fistulas. The average age was 40±15.13 years with extremes of 13 years and 75 years; 17 patients (37.8%) were older than 45 years. The average parity was 3 with extremes from 0 to 12 children. Multiparous women represented 68.8% of the patients. Obstetric VVF (OVF) was more frequent (48.9%) followed by iatrogenic VVF (33.3%). The mean age was higher in the IVF group compared to the VVF group (32 years) (P = 0.0004). Thirty patients were from the Dakar region and its suburbs (66.6%). The etiology of VVF did not vary according to the geographical origin of the patients (P=NS). VVF was frequently associated with the management of cervical cancer in 42.2% of cases. Comparison of our current data with previous series shows a reduction in the annual incidence of VVF. VVFs, although they have decreased significantly, are still predominant. There is a constant increase in the number of IVF. CONCLUSION: There is an evolution of the epidemiological and etiological profile marked by a decrease in the frequency of VVFs and an increase in that of IVFs. It is also worth noting the frequent association between cervical cancer and VVF. LEVEL OF EVIDENCE: Level 4: retrospective study.

Total penile glans amputation following circumcision: A case report of a dramatic complication.

Circumcision is one of the most commonly performed surgical procedures. As traditional ritual circumcisions are still practiced in the community, in Senegal the majority of circumcisions are performed in hospitals. We report the case of a 9-year-old boy who underwent a total amputation of the glans after a circumcision in a pharmacy by an unqualified agent. A meatoplasty was performed and the postoperative course were uneventful.

Experimental Study of a Heat Pump for Simultaneous Cooling and Desalination by Membrane Distillation.

Heat pump systems can simultaneously produce cooling energy for space cooling in hotels, office and residential buildings and heat for desalination using membrane distillation (MD). The MD technique uses a heat input at a temperature compatible with the levels of heat pump condensers (<60 °C). A heat pump prototype coupled with an air-gap membrane distillation unit was constructed and tested. This paper presents the experimental study on a lab-scale prototype and details the two operating modes "continuous" and "controlled" simulating an air conditioning system and a food storage, respectively. The experimental results enable to analyze the performance of the prototype and the physical phenomena involved. Finally, the study shows that this system could be a promising solution to help supplying freshwater to people in hot regions of the world.

Giant bladder diverticulum in a postmenopausal woman: Case report and literature review.

Bladder diverticulum represents a herniation of the bladder mucosa and submucosa through a point of weakness in the detrusor muscle. Bladder diverticula are rare and most often described in men. We report a symptomatic giant bladder diverticulum in a 56-year-old postmenopausal woman. The symptomatology was marked by acute urinary retention associated with abdominal-pelvic pain. A diverticulectomy by a transvesical approach with placement of a urethral catheter was performed. The postoperative course was uneventful.

Prostate rhabdomyosarcoma in a young adult: Case report and literature review.

Primary rhabdomyosarcoma of the adult prostate is rare and associated with an aggressive clinical course. Combined modality therapy has resulted in marked improvement in survival rates and reduced surgical morbidity for children with these tumors. However, in adults the prognosis remains poor.We report on a case of prostate rhabdomyosarcoma in an adult approached with combined-modality treatment, with the administration of 9 courses of doxorubicin, vincristine and endoxan, and, subsequent radiotherapy to the prostaticbed. The patient remained free of progression of disease for about 1 year.

Post-abortive vesicovaginal fistula associated with bladder lithiasis: About an observation.

Illegally induced abortions remain a significant public health issue in developing countries. We report a case that was complicated by a vesicovaginal fistula with intravesical calcification of the piece of wood used to perform the illegal abortion. A trans-vesical approach allowed extraction of the calcified foreign body and closure of the vesicovaginal fistula. The postoperative course was uneventful.

[Outcomes of radical prostatectomy in patients with prostate cancer at the Aristide Le Dantec University Hospital]. / La prostatectomie radicale: résultats carcinologiques au Centre Hospitalier Universitaire Aristide Le Dantec.

The purpose of this study was to assess outcomes of radical prostatectomy in patients with prostate cancer. We conducted a retrospective single-center study in the Department of Urology and Andrology at the Aristide Le Dantec Hospital in Dakar from June 1, 2010 to May 31, 2016. We collected data of 60 patients undergoing radical retropubic prostatectomy associated with dissection of the iliac and obturator nodes. After radical prostatectomy, prostate specific antigen (PSA) levels were undetectable (<0.1 ng/mL) in 20 patients (33.3%). Eleven patients (18.3%), who had biochemical relapse, received complementary hormone therapy. Patients achieved a response after initiation of treatment, and total PSA became undetectable again after an 8-month follow-up period. Mean overall survival was 17.5 months, with a median of 9.49. Cumulative overall survival rates at 1 year, 3 years and 4 years were 42.4, 13.6 and 6.8%, respectively. Mean relapse-free survival was 17.3 months, with a median biochemical relapse-free survival of eleven (11) months. The mean duration of specific survival was 8.1 months, with a median of 3 months. Seven patients had positive resection margins (11.6%). Four patients had lymph node involvement. Radical prostatectomy, suggested in some patients with prostate cancer in our practice, has been shown to be an effective therapeutic method leading to good outcomes.

[Results of two-level urethroplasty according to Bengt Johanson for complex urethral strictures in adults]. / Resultats de l'uretroplastie en deux temps selon Bengt Johanson pour les stenoses uretrales complexes de l'adulte.

AIM: to evaluate the results of two-level urethroplasty in the treatment of complex urethral strictures in our clinical center. PATIENTS AND METHOD: Thiswas a retrospective cross sectional study from January 2012 to September 2015 in our clinical center. Patients operated according to Bengt Johanson technique were included. The parameters studied were age, the urological history, consultation reasons, duration of evolution, stenosis characteristics and treatment outcomes. RESULTS: twelve patients were enrolled in our study. The mean age was 48 ± 20 years. The main reason consultation reason is urine retention. The mean duration of evolution was 30 ± 25 months. The most common etiology identified was scleroinflammatory one . All the patients already had at least one medical background. The physical examination showed a periurethral gangue in 10 patients. The mean length of the urethral stricture was 6.3 ± 2.2 cm. After an average follow-up of 3.8 ± 2.3 months; the treatment outcomes were considered satisfactory in 8 patients and bad in 4 patients. CONCLUSION: Bengt Johanson's two level urethoplasty gives good outcomes in the treatment of complex urethral strictures.

Impact of tumor cytoreduction in metastatic prostate cancer.

Objective: To assess the impact of tumor cytoreduction on cancer outcomes and patient survival in metastatic prostate cancer. Patients and methods: It is a prospective study spanning a two-year period between October 1st 2015 and March 31st 2017. We enrolled 102 cases of metastatic hormone-sensitive prostate cancer. Fifty-seven (57) patients had exclusively androgen deprivation therapy (ADT) (group 1) and 45 had, in addition, an open prostatectomy or Transurethral resection of the Prostate (group 2). We compared both groups using the total PSA nadir, the time to PSA nadir, the overall survival (OS), and the progression-free survival (PFS). Results: The average nadir PSA was lower for the tumor cytoreduction group (16.8±1.6 ng/mL (0.01-193.5) versus 110.7±17.9 ng/mL (0.01-1379)). Median time to PSA nadir was shorter in patients in the ADT only group (8 months vs 3 months (p=0.025)). The OS was shorter in patients treated with ADT only compared to the tumor cytoreduction group (median 14 months vs 24 months, respectively (p=0.03)). Similarly, tumor cytoreduction had a positive impact on patient progression (median PFS 20 months (group 1) vs 43 months (group 2)). Conclusion: Tumor cytoreduction has a positive impact on the oncological results and the survival of patients under ADT.

Salmonella Serogroup C: Current Status of Vaccines and Why They Are Needed.

Nontyphoidal Salmonella (NTS; i.e., Salmonella enterica organisms that do not cause typhoid or paratyphoid) are responsible for 94 million infections and 155,000 deaths worldwide annually, 86% of which are estimated to be foodborne. Although more than 50 serogroups and 2,600 serovars have been described, not all Salmonella serovars cause disease in humans and animals. Efforts are being made to develop NTS vaccines, with most approaches eliciting protection against serovars Typhimurium and Enteritidis (serogroups B [O:4] and D [O:9], respectively), as they are widely considered the most prevalent. Here, we show that serogroup C (O:6,7, O:6,8, or O:8 epitopes) is the most common serogroup in the United States, and the prevalence of serovars from this serogroup has been increasing in Europe and the United States over the last decade. They are also the most commonly isolated serovars from healthy cattle and poultry, indicating the underlying importance of surveillance in animals. Four out of the 10 most lethal serovars in the United States are serogroup C, and reports from African countries suggest that strains within this serogroup are highly antibiotic resistant. Serogroup C consists of highly diverse organisms among which 37 serovars account for the majority of human cases, compared to 17 and 11 serovars for serogroups B and D, respectively. Despite these concerning data, no human vaccines targeting serogroup C NTS are available, and animal vaccines are in limited use. Here, we describe the underestimated burden represented by serogroup C NTS, as well as a discussion of vaccines that target these pathogens.

Capital and operating costs of full-scale fecal sludge management and wastewater treatment systems in Dakar, Senegal.

A financial comparison of a parallel sewer based (SB) system with activated sludge, and a fecal sludge management (FSM) system with onsite septic tanks, collection and transport (C&T) trucks, and drying beds was conducted. The annualized capital for the SB ($42.66 capita(-1) year(-1)) was ten times higher than the FSM ($4.05 capita(-1) year(-1)), the annual operating cost for the SB ($11.98 capita(-1) year(-1)) was 1.5 times higher than the FSM ($7.58 capita(-1) year(-1)), and the combined capital and operating for the SB ($54.64 capita(-1) year(-1)) was five times higher than FSM ($11.63 capita(-1) year(-1)). In Dakar, costs for SB are almost entirely borne by the sanitation utility, with only 6% of the annualized cost borne by users of the system. In addition to costing less overall, FSM operates with a different business model, with costs spread among households, private companies, and the utility. Hence, SB was 40 times more expensive to implement for the utility than FSM. However, the majority of FSM costs are borne at the household level and are inequitable. The results of the study illustrate that in low-income countries, vast improvements in sanitation can be affordable when employing FSM, whereas SB systems are prohibitively expensive.
