The present study conducted in the town of Ombessa aims to assess the influence of abiotic factors on the abundance dynamics and antibiotic susceptibility of Escherichia coli and Enterococcus faecalis isolated from some aquatic systems from February to July 2022, monthly samples were taken at 10 water points used by the population (8 groundwater points and 2 surface water points). Samples were analyzed for physico-chemical parameters such as temperature, pH, electrical conductivity. Bacteriological variables such as BHAM, E. coli and E. faecalis abundances were also assessed. Antibiotic susceptibility of E. coli and E. faecalis was assessed using 06 antibiotics using the Kirby-Bauer diffusion disk method. The results show that bacterial abundances were the highest in surface waters. Bacterial densities were the highest in May and the lowest in February. The average densities recorded were 3845 CFU/100mL for BHAM, 380 CFU/100mL for E. coli and 14 CFU/100mL for E. faecalis in groundwater;and 8583 CFU/100mL for BHAM, 6878 CFU/100mL for E. coli and 812 CFU/100mL for E. faecalis in surface water. Antibiotic susceptibility tests showed that these bacterial species are sensitive to Gentamicin, Chloramphenicol, Azithromycin and Ciprofloxacin. They are all resistant to Trimethoprim/Sulfamethoxazole, E. coli is resistant to Doxycycline and E. faecalis has an intermediate sensitivity to Gentamicin. Overall, the Multiresistance to Antibiotics (MRA) indices obtained were above 0.2, indicating the presence of multidrug resistance in bacterial communities. The physico-chemical properties of the water varied over time and space, but on the whole remained below the threshold values of WHO guidelines. The degree of linkage between abiotic water variables and bacteriological parameters has shown that bacterial densities are more abundant in rainy seasons and increased O2 levels favor bacterial growth, while TSS, CO2 and dissolved nitrate levels affect the sensitivity of these bacteria

Introduction: Thoracoscopy is a video-assisted surgical approach that mirrors the techniques used in thoracotomy. Our aim is to map the current state of thoracoscopy practice in Cameroon’s hospitals. Methods: This was a descriptive study that collected both retrospective and prospective data over 57 months across four hospitals in Cameroon. It included 13 patients and focused on variables such as socio-demographic factors, clinical profiles, surgical procedures, and postoperative follow-up. Results: Thirteen patients, predominantly male (84.6%, n = 11), with a mean age of 37.5 ± 16 years, were enrolled. Alcohol use (61.5%) and smoking (38.5%) were the most common past histories. The major complaints were dyspnea (84.6%) and chest pain (58.3%). The primary surgical procedure was clot-free thoracoscopy in 30.8% of cases, mainly for persistent hemothorax (41.8%). Most surgeries were elective (76.9%) and performed under general anesthesia with selective intubation (61.5%). The most common approach was single-port thoracoscopy (U-VATS) (76.9%), with no reported difficulties;however, one intraoperative incident occurred and was successfully treated. Drainage was performed systematically in all patients, and one case required conversion to open surgery. Postoperative complications were minor (Clavien-Dindo grade I) and mainly consisted of pain, with a mortality rate of 15.4%. No significant association was found between risk factors and the occurrence of complications or postoperative mortality. Conclusion: Thoracoscopy, a novel approach in our context, primarily focuses on minor thoracic surgeries.

Twisting of the Spermatic Cord in an Elderly Subject at the Yaounde Central Hospital: About a Case

Open Journal of Urology 2022年第7期12卷 394-400页

Introduction: Twisting of the spermatic cord is part of urological emergencies. It can occur at any age with a predilection for children and adolescents. There is no literature on spermatic cord torsion in octogenarians, probably due to its rarity. The majority of recent studies show spermatic cord torsion in patients under 55 years of age. This is why we present a case of spermatic cord torsion in an 80 years old subject. Case Presentation: We present a case of torsion of the spermatic cord in an 80-year-old subject. The diagnosis was made on anamnestic and clinical grounds. The patient presented with scrotal pain, unilateral, of sudden onset, violent intensity without urinary signs with an ascended testicle. The urine dipstick was unremarkable. Management was done surgically and as an emergency. The postoperative course was satisfactory. Conclusion: Spermatic cord torsion in octogenarians is exceptional and should be suspected in the first instance in the presence of any sudden onset, severe testicular pain without urinary signs with an ascended testicle and a negative urine dipstick.
