Introduction: Prostate cancer is the leading urological cancer. It is the most common cancer in men over 50. Objective: To determine the epidemiological, diagnostic and therapeutic characteristics of prostate cancer in hospitals in the Thiès region. Patients and Methods: We conducted a descriptive study from January 1st, 2015 to December 31st, 2020. We included all cases of primary prostate cancer confirmed on histology. Results: We collected data on 318 cases of primary prostate cancer during the study period. Mean patient age was 72.7 years (Range: 49;94 years). Family history of prostate cancer was found in 22 patients (6.91%). The average consultation time was 18.6 months. The circumstances of discovery were dominated by obstructive voiding disorders (97.16%). Digital Rectal examination was suggestive in 55.40% of patients. PSA level was above 20 ng/ml in 76.7% of patients. Prostatic adenocarcinoma was the only histological type (100%). Localized cancer represented 7.2% and locally advanced cancer occurred in 36.5% of cases, while metastatic cancer accounted for 56.3%. Radical prostatectomy was performed in 3.18% of cases. Mortality rate was estimated at 8.50% after 1 year. Conclusion: Prostate cancer is the leading urological cancer in the Thies region. It is characterized by the predominance of locally advanced and metastatic forms.

Digestive surgical emergencies concern all patients admitted urgently, for whom a decision for surgical intervention may be necessary within 24 hours. They are on guard duty day and night. To carry out this work, we set ourselves the objectives of: 1) Studying digestive surgical emergencies in the general surgery department of the “Mother Child” Le Luxembourg hospital in Bamako, Mali;2) Determine the frequency of digestive surgical emergencies, 3) Describe the clinical and therapeutic aspects, and 4) Analyze the results of treatment. From November 1, 2022 to October 31, 2023, the general surgery department of the “Mother Child” Luxembourg Hospital Center in Bamako, Mali, carried out 139 digestive surgical emergencies whose files were usable;75 men and 64 women, a sex ratio of 1.2. The 20 - 40 years old age group was the most represented, at 40.29%. The average age was 39 years;the extremes 16 years and 93 years with a standard deviation of 21.65 years. The reference concerned 51.08% of our patients. Abdominal pain was the main reason for consultation (100% of cases). In the majority of cases, the physical examination made it possible to make the diagnosis. Faced with certain clinical cases, we requested ultrasound (109/139), ASP (46/139) and CT (15/139). The main etiology was acute appendicitis with 42.45% of cases. The frequency of digestive surgical emergencies was 10.71% of all activities in the general surgery department of the “Mère Enfant” Le Luxembourg hospital center in Bamako. All our patients were seen in consultation by an anesthesiologist before entering the operating room. The surgical consequences were complicated in 11.51% of cases with 7.91% deaths. Surgical site infections accounted for 12.5% of postoperative complications. Eleven deaths were noted, representing 68.75% of complications and 7.91% of our sample. Acute peritonitis was the cause of death in 100% of cases. The average cost of care was 329,000 FCFA.

The objectives of this work were to evaluate the surgical activities carried out in the general surgery department of the Reference Health Center of Commune I of Bamako, to describe the sociodemographic characteristics of the operated patients, to determine the main pathologies encountered and to evaluate qualitatively the result of the treatment. In order to improve performance, and the quality of care, and to identify common pathologies in the surgical department, we undertook a retrospective study on surgical activities from January 2009 to December 2010. At the end of this study, out of 474 men and 187 women (equal sex ratio 2.53);we were able to determine the frequency of surgical pathologies. Farmers, housewives and pupils/students were the most represented with 25.9% respectively;20% and 13.3%. The most frequently observed pathologies were wall hernia (44.8%), prostate adenoma (12%) and acute appendicitis (10.5%). The average length of hospitalization was 3.43 days. Infectious complications affected 25 patients (3.8% of cases) and a death rate of 0.45% (i.e. 3 patients). The average cost of care was 53,500 FCFA. Indeed, the reality of surgical practice in health centers was not the same because of the level of skills of practicing surgeons.

Over the years, pineapple production in the Republic of Guinea has become less competitive in the West African sub-region, with a world ranking of 144th. It is therefore only natural to review certain parameters in order to improve this ranking. To do this, certain physico-chemical parameters of soil samples from Friguiagbé and Maferinyah (in the Kindia and Forécariah prefectures) were taken and analysed using the following techniques: Pipette de Robinson, Anne, Bray II, Kapen HICDVITZ, Mc. Lead (1982). The analytical results show that the soils at Friguiagbé in Kindia and Maferinyah in Forécariah are acidic, with pH values of 4.4 and 4.7 (fields I and II) and 4.8 and 4.7 (fields I and II) respectively. The soils have a silty-sandy texture. This study could therefore serve as a guide for the Ministry of Agriculture of the Republic of Guinea.

This study aims to identify the causes of sensor jams and its impact on the operation of vending machines. The vending machine is a machine that automatically dispenses products such as drinks, tickets, sandwiches and biscuits, by inserting change or credit card into the machine. This technological feat is due to the advent of sensors. A sensor is a part of the measurement chain, it receives the quantity to be measured and provides information directly linked to this quantity. However, these vending robots are faced with malfunctions linked to sensor jams. The identification of the jam phenomenon was possible thanks to the inspection and monitoring of the various sensors installed on the vending robot. And Cadence software was used to model, control and locate the jammed sensor(s). The various tests were carried out by setting the robot in motion to better understand the causes of the phenomenon. The jam is therefore the phenomenon which triggers the sensors permanently, which causes the automatic vending robot to stop functioning. And this jam was due to the presence of water droplets on the sensor or dirt. This presence of water droplets on the sensor is linked to an increase in temperature. Controlling the temperature and locating the jammed sensor has made it possible to considerably reduce jamming and its harmful effects on the vending machine robot.

This work was a prospective transversal study over 6 (six) months from May 2 to December 31, 2017 at the Reference Health Center of Commune I and the Chérif la Confessional Health Center in Bamako. The aim was to study the knowledge, attitudes and behavioral practices linked to hemorrhoids in Commune I of the Bamako district, to evaluate the frequency of hemorrhoidal disease, to determine the knowledge, attitudes and behavioral practices linked to hemorrhoids among patients, their companions and traditional therapists in Commune I of the district of Bamako and the factors which influence the motivations and decisions to resort to medical-surgical care and traditional medicine in patients suffering from hemorrhoids in order to analyze the results of the management of hemorrhoidal disease at Cs Ref CI. We collected 36 patients with hemorrhoidal disease, 25 caregivers and 15 traditional hemorrhoidal disease therapists. The sex ratio was 1.25 for patients;6.5 for traditional therapists and 1.5 for accompanying people. The average age of the patients was 32.75 years;49 years for traditional therapists and 28.76 years for those accompanying them. 55.6% of patients claim to know about hemorrhoidal disease;100% of traditional therapists and 80% of accompanying people. The dietary factor of hemorrhoidal disease was mentioned by 90% of patients;66.7% of traditional therapists and 100% of caregivers. Most patients initially resorted to traditional treatment out of fear of surgery and its after-effects. The patients were treated medically and surgically.

It was a 36-year-old patient, 5th Pregnancy, 5th Delivery, 4 live children, and I deceased, had a consultation in the department for the removal of implants. Questioning revealed that she had had the implant three years ago without medical follow-up. It was in view of the difficulties in extracting the capsule that the chest X-ray and CT scan carried out concluded that the implant had migrated into a branch of the left pulmonary artery. Therapeutic abstention has been the attitude of cardiovascular surgeons.
