Objective: To study erectile dysfunction in diabetic patients seen in two clinics in the city of Bobo-Dioulasso, Burkina Faso. Materials and Methods: A prospective cross-sectional descriptive study was conducted at the Souro Sanou Teaching Hospital (CHUSS) and the Saint Leopold clinic in Bobo-Dioulasso, from March 1 to September 1, 2012. A total of 107 patients data were collated and analysed, which was then grouped into two: the eD group, designating patients with erectile dysfunction and the NeD group consisting of those patients without. The sample comprised of 61 patients with types 1 and 2 diabetesand were aged between 25-70 years. The IIeF-5 was used to evaluate erectile dysfunction. Results: The prevalence of erectile dysfunction was 57%. The average age of patients was 54.4 ± 8.3 years. All patients with eD had type 2 diabetes. The mean disease duration of diabetes was 7.2 ± 6 years. erectile dysfunction was severe in 32.8% of cases, moderate in 31.1% of cases and mild in 36.1%. Its severity was significantly associated with glycated hemoglobin, triglycerides and BMI. Phosphodiesterase types 5 (PDe5) inhibitors were found to be effective in the treatment of erectile dysfunction with a satisfactory therapeutic response in 77.4% of users. Conclusion: erectile dysfunction is a common complication in diabetic patients. Its occurrence and severity are influenced by several factors. The potential presence of this disorder should be assessed due to its negative impact on quality of life. Phosphodiesterase type 5 inhibitors are an effective treatment modality in diabetic patients.

We reported a case of an intravesical foreign body in a 16 years old teenager for abortion attempt. During laparotomy for suspected pelvic appendicitis, we incidentally discovered an intravesical foreign body. From this first observation in our urology division, we reviewed the literature on the nature and circumstance of self introduction in bladder of foreign body and their surgical ablation. We emphasized the importance of endoscopy as a support of diagnosis and therapeutic of intravesical foreign body. This observation also highlighted the lack of information in our teenagers about reproductive and sexual health.

The authors report a severe form of genitoperineal localisation of Verneuil’s disease managed in a surgical environment, having evolved favorably with improvement of the patient’s quality of life, but persistence of unsightly skin scars. They insist on the unexceptional nature of this disease whose prognosis is reserved, sometimes leaving severe functional sequelae. The long evolution of the disease with prolonged hospitalization in a professionally active young patient and the extension of suppurations to the perineal, scrotal and inguinal regions was the features of this observation. After wide excision of the lesions with antibiotic associated with local care, evolution had taken to complete wound healing with improved quality of life and a recovery of his professional activity.

We conducted a cross-sectional study between February 1st, 2012 and September 30, 2012 at Bobo-Dioulasso University Teaching hospital. The target population was all patients seen at the emergency services for acute urinary retention. Among the 155 patients admitted for urological emergencies, 104 (67.1%) had acute urinary retention. The average age of patients was 65 years, ranging from 23 to 89 years and the majority was more than 60 years old (77.8%) and lived in rural areas (64.4%). Prostate tumor pathology and urethral stricture were the most frequent diagnosis, and the renal function was impaired in 33.7% of cases. Urethrovesical drainage, cystocatheterism, and suprapubic cystostomy were the treatment approach in 56.0%, 28.0% and 15.2% of the cases. Acute urinary retention is the most common urological emergency and many complications are associated with urethrovesical sounding. These complications should therefore be prevented by improving acute urinary care.

Naturally occurring tubular halloysite is a potential drug carrier because of the significant deposit, unique mesoscopic (2-50 nm) or even macroscopic (>50 nm) lumen, and excellent biocompatibility. The drugs loaded on halloysite exhibited slow release under the diffusion limitation by the halloysite nanotube. However, due to the weak interaction between halloysite and guest, the loading capacity of halloysite was relatively low. This drawback severely limits the application of halloysite as carrier in pharmaceutics. In this study, the performance of halloysite as carrier for ibuprofen (IBU) loading was investigated for the first time. The effects of 3-aminopropyltriethoxysilane (APTeS) modification and thermal treatment of halloysite on the loading and release of IBU were also studied. The purified halloysites were heated at 120 ℃ and 400 ℃ (labeled as Hal/120 and Hal/400), and then modified with APTeS (labeled as Hal/120-A and Hal/400-A). The loading of IBU was achieved by soaking method (labeled as IBU-Hal/120, IBU-Hal/400, IBU-Hal/120-A, and IBU-Hal/400-A.). The in vitro drug delivery assays were performed in phosphate buffer solution. IBU was loaded mainly into the lumen and partially on the external surface of halloysite. The order of IBU contents was as follows: IBU-Hal/400-A (14.8wt%) > IBU-Hal/120-A (12.7wt%) > IBU-Hal/400 (11.8wt%) > IBU-Hal/120 (11.7wt%). The IBU was initially anchored to the surface hydroxyl groups of halloysite by hydrogen bonding, followed by further bonding of IBU with the anchored IBU to form hydrogen-bonded aggregates. The APTeS modification of halloysite promoted the loading of IBU by introducing a strong affinity through electrostatic attraction between the introduced aminopropyl groups of APTeS and the carboxyl groups of IBU. Thermal treatment at 400°C did not destroy the tubular morphology or the crystal structure of halloysite and had little effect on IBU loading in unmodified halloysite. However, thermal treatment by reducing
