Introduction: External otitis (OE) is an acute or chronic inflammation or infection of the external ear resulting from an imbalance in the external auditory canal secondary to microtrauma, maceration, eczema, or a foreign body in the external auditory canal. Objective: To study cases of external otitis at the Mamou Regional Hospital. Materials and Methods: This was a prospective descriptive study conducted over a period of six (6) months from July 1st to December 31st, 2016. It included all patients admitted to the ENT department of the Mamou Regional Hospital. Results: During the study period, 712 patients were admitted to the department for various pathologies, of which 103 met our selection criteria, representing a frequency of 14.46%. The mean age of the patients was 33.74 years with a range of 1 to 90 years. Males predominated in the sample, accounting for 59.22%. The vast majority of patients resided in urban areas, constituting 61.17% of the sample. In our study, all patients consulted for otalgia (100%), and over half (53.39%) for hypoacusis. We formally identified rhinitis in 66.66% of cases, while diabetes was found in only 4 patients (11.11%). Otomycosis was the most commonly identified condition (53.39%), followed by furuncles (33.98%). Ear drops containing antibiotics were administered to all patients, although 66.60% received antibiotic therapy. Conclusion: External otitis is a relatively common condition, particularly among children and the elderly. Diagnosis can be made based on pain upon traction of the pinna and pressure on the tragus.

Introduction: Otorhinolaryngological (ORL) and cervicofacial traumas encompass injuries affecting the neck, face, and ORL region, resulting from external influence. The objective of this study was to conduct an epidemiological and clinical analysis of ORL and cervicofacial injuries observed in victims of road accidents treated at the Otorhinolaryngology (ORL) department of the Regional Hospital of Mamou. Materials and Methods: This prospective and descriptive study was conducted over a period of 12 months, from January 1st to December 31st, 2021, within the Otorhinolaryngology (ORL) department of the Regional Hospital of Mamou. It included patients hospitalized for ORL and/or cervicofacial traumas resulting from road accidents during the study period. Results: A total of 348 cases were included, representing 36.22% of all traumas related to road accidents (AVP) within the Regional Hospital of Mamou. The average age of the patients was 26.44 years, with a sex ratio of 3.83, favoring males. The dominant socio-professional category was students, encompassing 32.47% of cases. Road accidents were mainly associated with motorcycle use (31.32% motorcycle-to-motorcycle, 24.43% motorcycle skidding, 13.51% motorcycle-pedestrian). Facial region injuries were the most common, accounting for 69.03% of cases, followed by rhinological injuries (17.28%) and otological injuries (13.69%). Associated injuries were predominantly closed head traumas (52.55%) and lower limb fractures (20.41%). Imaging was underutilized. Regarding surgical interventions, reconstructive surgery was the most predominant, accounting for 52.51% of cases, with a management timeframe of 30 minutes to 12 hours for 99.72% of patients. Conclusion: Road traffic accidents remain a serious public health issue, primarily affecting young males. Emphasis should be placed on road safety measures to reduce the frequency of these accidents.

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.

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.

Pleomorphic adenoma is the most common tumor of the salivary glands, accounting for approximately 50% of salivary gland lesions. It develops mainly in the salivary glands: parotid (80%), submaxillary (10%), sublingual (1%) and in the accessory oral-pharyngeal glands (9%). The aim of this work was to report 2 cases of pleomorphic adenoma of atypical location and then to discuss the difficulties linked to its diagnostic and therapeutic management in the Malian context. They were a 40-year-old man and a 72-year-old woman. They were admitted to the ENT department of the “Luxembourg Mere-infant” hospital for oropharyngeal swelling for the first and swelling of the palate for the second. The clinical expression was a swelling in both cases, of a hard, mobile consistency with healthy mucosa on their surface. The remainder of the physical examination was unremarkable. The diagnosis of a tumor of the oropharynx and palate was made following clinical radiological examinations. The histopathological examination of the surgical specimen made it possible to make the diagnosis of pleomorphic adenoma of the palate and the left palatine tonsil. The follow-up surgery was straightforward, with a favorable outcome. Pleomorphic adenomas are relatively rare benign tumors of the accessory salivary glands;their clinical expression remains swelling. Therapeutic management is surgery and the diagnosis is confirmed by histopathological examination.

Introduction: Cardiac catheterisation plays a fundamental role in the management of acute coronary syndrome. These explorations require heavy, complex and costly equipment and a large team of doctors, nurses and technicians with highly specialized training. Aims: To describe epidemiological, clinical and coronary angiography aspects of patients with acute coronary syndrome. Patients and Methods: Descriptive study from September 2019 to December 2023 in the Cardiology Department of the Hôpital Mère-Enfant of Bamako. Inclusion criteria were patients admitted for coronary angiography with the diagnosis of acute coronary syndrome. Results: During the study period, 1253 patients underwent coronary angiography, 596 of whom had acute coronary syndrome as an indication, representing a hospital frequency of 47%. Sex-ratio was 2.10. Mean age of patients was 58.5 ± 11.39 years. ST elevation acute coronary syndrome was the most common indication with 63.92% of cases. High blood pressure was the main cardiovascular risk factor with 58.7% of cases, and radial access approach was used in 98% of cases. Coronary angiography was pathological in 91.70% of cases (n = 548). Patients with lesions of anterior interventricular artery were 73.73% of cases. Tritruncal lesions accounted for 40.63% of cases. Conclusion: ST elevation acute coronary syndrome is the most frequent manifestation of acute coronary syndrome. Anterior interventricular artery is most often the culprit lesion for our patients.

Introduction: Open transvesical prostatectomy remains today one of the most effective approaches for the management of benign prostatic hyperplasia despite the fact that, this method is associated with multiple complications. The objective of this study was to evaluate the influence of prostate weight on the morbidity and mortality of transvesical prostatectomy for adenoma in the urology-andrology department of the Ignace Deen National Hospital. Materials and Methods: This was a prospective, longitudinal and analytical study lasting 6 months, from March 1, 2022 to August 31, 2022 including patients admitted and operated on by open transvesical prostatectomy by assessing the influence of prostate weight on the morbidity and mortality of transvesical adenomectomies. Results: 108 patients were included in our study, the average age of our patients was 70 ± 7.7 years, cultivators were the most represented profession with 38.89%, and hypertension was the most represented comorbidity with 75%. 33.06% of cases became complicated and surgical wound infection was the main complication with a frequency of 17.40%. Statistical analysis did not conclude that, the prostate weight does not have a statistically significant influence on the morbidity and mortality of transvesical open prostatectomy for benign prostatic hyperplasia. Conclusion: Prostate weight has no influence on the morbidity and mortality of transvesical prostate adenoma.
