A foreign body, whatever its nature, is often involved in its genesis. To date, there is very little data on foreign body conjunctival granulomas, the prevalence would be approximately 10% and their underestimation is probably linked to the inconsistency of their clinical presentation. Patient and Observations: We report a case of conjunctival granuloma caused by a metallic foreign body that went unnoticed in a young boy, the interest of rigor on primary protection measures for high-risk occupations, and of the strict application of the diagnostic protocol relating to ocular trauma. Discussion: foreign body granulomas, despite their usually harmless nature, can jeopardize the anatomical and functional prognosis of the affected eye. Only a detailed interview and a meticulous clinical examination allow the diagnosis to be made and the distinction to be made with conjunctival granulomas of different causes. Conclusion: the possibility of the involvement of a foreign body in the genesis of conjunctival granulomas must impose the rigorous application of diagnostic and therapeutic protocols.展开更多

The aim of this study was to describe the clinical, etiological and prognostic aspects of acute fever in children aged 0 - 15 years. Patients and Methods: This was a prospective cross-sectional study from April 1, 2021 to March 31, 2022 and affected all children aged 0 to 15 years old with a temperature of 39˚C or higher (≥), having less than five days and hospitalized in the pediatric department of the Gabriel Touré University Hospital. Results: During the study period, 150 children were included, the sex-ratio was 0.85. Children aged 0 - 5 years represented 71.4% of the sample. References represented more than half of the sample, or 58% of cases. Body temperature was above 40˚C in 18.7% of cases. Functional signs were dominated by respiratory signs in 28% and digestive signs in 18%. Clinical pallor was found in 55.3% of children associated with signs of respiratory struggle in 70% of cases and tachycardia in 40% of patients. Anemia was present in 65.3% of patients. Hyperleucocytosis and leukopenia were found in 45.3% and 43.3% of patients respectively. The C-reactive protein was positive in 44.7% of patients and Cytobacteriological Examination and Chemistry of Cerebrospinal Fluid was positive in 8.7% of cases. The thick drop was positive in 44.7% of patients and blood cultures grew in 6 patients. Etiology was dominated by severe malaria 54 cases (36%), pneumonia (19.3%), meningitis (12.6%), and in those under one month it was bacterial neonatal infection (8.6%). In our study, slightly more than one patient out of three died during hospitalization, 36% (54 cases/150) and among these 70% (38 cases/54) were under 5 years old. The most lethal pathologies were severe malaria (36%), bacterial pneumonia (19.3%), meningitis (12.6%), bacterial neonatal infections (8.6%) and measles complicated by pneumonia (5.3%). Mortality during hospitalization was 36% of deaths (54 out of 150 patients) and 70.3% (38/54) of the deceased patients were under 5 years old. Conclusion: This study shows that fever is a frequent symptom and a sign of serious and very lethal pathologies. The cause of fever can be a diagnostic challenge for health workers. However, early identification of children at risk for serious illness could allow for prompt and appropriate management in appropriate settings.展开更多

Eye diseases with a prevalence associated with age and aging will continue to increase in the coming years. Most studies conducted on problems in middle-aged people have focused on visual disorders without taking into account all the ocular morbidities that may affect this segment of the population, hence the present study, the aim of which is to determine the proportions of different eye diseases in people aged 40 and over. Materials and Methods: This was a descriptive cross-sectional study carried out in the ophthalmology department covering the period from January 1 to December 31, 2020. Results: In total, we collected 828 patients aged 40 and over out of 1811 patients who received ophthalmological consultation during the study period, representing 45.72%. The most represented age group was 40 - 50 years, with an average age of 58.84 years and a maximum of 93 years. There were slightly more women (62.3%) than men (37.7%). The main reasons for consultation were decreased visual acuity (26.4%) and pruritus (19.9%). The main eye diseases diagnosed were cataracts (23%), allergic conjunctivitis (21.1%), and bacterial conjunctivitis (14.2%). Discussions: The predominance of cataracts in the diagnosed diseases confirms the literature data, according to which the main eye morbidities in middle-aged and elderly people are cataracts, glaucoma, and age-related macular degeneration. Conclusion: It is crucial to have a mastery of these epidemiological data of eye diseases in order to adapt the technical platforms of eye care structures to the needs of different segments of the population.展开更多

The requirements of this type of vessel are always special, and their availability is limited. To prepare for the future development of South China Sea deepwater projects, the China Offshore Oil Engineering Corporation has recently built a heavy lift transport vessel-Hai Yang Shi You 278. This semi-submersible vessel has a displacement capacity of 50k DWT, and a breath of 42 meters. Understanding the vessel＇s applicability and preparing it for use in future deepwater projects are becoming imminent needs. This paper reviews the current critical issues associated with TLP transportation and performs detailed analysis of the designed TLP during load-out and transportation. The newly built COOEC transportation vessel HYSY 278 was applied to dry transport of the TLP structure from the COOEC fabrication yard in Qingdao to an oil field in South China Sea. The entire process included the load-out of the TLP structure from the landsite of the fabrication yard, the offloading and float-on of the platform from the vessel, the dry transport of the TLP over a long distance, and the final offloading of the platform. Both hydrodynamic and structure analysis were performed to evaluate the behavior of the transport vessel and TLP structure. Special attention was paid to critical areas associated with the use of this new vessel, along with any potential limitations. The results demonstrate that HYSY 278 can effectively be used for transporting the structure with proper arrangement and well-prepared operation. The procedure and details were presented on the basis of the study results. Special attention was also given to discussion on future use based on the results from the analysis.展开更多

Patients and Methods: This was a descriptive study conducted in our General Surgery Department. It took place in two phases for six years: A retrospective phase from January 1st, 2010 to December 31st, 2015 and a prospective phase from January 1st, 2016 to December 31st, 2017. This study has been approved by the Ethics Committee. It’s concerned all the patients operated in the department for colon Volvulus. Results: We collected 70 patients’ files. The Sigmoid Volvulus represented 7.8% of emergency surgery activities and 37.2% of intestinal obstruction. The male sex predominated with 98.57% against 1.43% of the female sex. The average age was 42.11 years old with limits of 18 to 70. The average deadline evolution was 2.53 days with limits of 1 to 3. The sigmoidectomy with immediate anastomosis was performed in 66% of patients, colectomy with 2-times anastomosis: according to Hartman 20% and Bouilly Volkman 11%, detorsion with colopexy 3%. The early morbidity rate was 5.71%. The average duration of hospitalization was 10.8 days with limits of 5 to 40 days. Two deaths were recorded. Conclusion: Sigmoid Volvulus is frequent in young adult sex male in Africa. We did not find any significant difference between the surgical technique and the advent of complications. The Colectomy with immediate anastomosis seems to be ideal to us that anytime the conditions are appropriate.展开更多

Patients who have to undergo urology surgery are exposed to infectious complications if there is an untreated urinary tract infection. The objective of our study is to identify all the germs responsible for urinary tract infections discovered in the preoperative assessment of hospitalized patients with their susceptibility and antibiotic resistance profiles. Patients and Methods: This is a retrospective and descriptive study of 124 cases of cytobacteriological examination of urine collected over 2 years from January 1st, 2016 to December 31st, 2017, performed in the urology department of the University Hospital of Bocar S. Sall of Kati. The parameters studied were: age, sex, reason for admission, the diagnosis chosen, the result of the cytobacteriological examination of urine and the antibiogram. Results: We collected 124 cases of cytobacteriological examination of urine during this period. The average age of our patients was 58 years old with extremes ranging from 3 years to 84 years. The sex ratio was 6 in favor of men. 86 patients, or 69%, were admitted for micturition disorders. In 53.2%, the diagnosis was BPH followed by urolithiasis 22.6%. Cytobacteriological examination of urine identified 55 cases of urinary infection, 44%. In 34 cases or 60%, the germ responsible was an E. coli. Two germs were sensitive only to one antibiotic. Conclusion: This study made it possible to have an idea about the antibiotic susceptibility of germs involved in urinary tract infections. Awareness-raising for the proper use of antibiotics needs to be strengthened to minimize the risk of increasing antibiotic resistance.展开更多

Most of these accidents are of cardiovascular origin. Moreover, data on ECG or Echocardiography are rare in our context justifying our study to assess electrical and echocardiographic pattern among high-level footballer in Bamako. Methods: It was a cross-sectional study conducted in Bamako from April 2015 to?March 2016 among high-level footballers aged 14 to 35 years old without distinction of sex with at least 10 hours weekly training since one year. The ECG and echocardiographies were recorded respectively with a 12-lead CONTEC and an ATL 5000 echocardiographic machine. Each ECG record was analyzed by a cardiologist in accordance with the Seattle 2013 criteria and those pathological reviewed by a second cardiologist according to the same criteria and definitively classified as normal (physiological) or abnormal ECG (requiring complementary explorations). A third cardiologist was associated in case of discordance of the first results. The collected data were inserted in a Microsoft Excel sheet and analyzed with SPSS version 20. Chi Square and Fisher statistical tests were used to compare our results. The significance level was set at 0.05. Results: We collected data of 227 top footballers with male sex represented in 90.3% giving a sex ratio of 3.04. Means for age, weight, height, body mass index (BMI) were respectively 22 years, 69.90 kg, 177.21 cm and 22.21 kg/m2. Sinus bradycardia was found in a proportion of 45.8% more represented in the age group of 30 and more years (p = 0.275). First-degree atrioventricular block (AVB) was present in 19.4%. Short PR was found in 0.4% of the sample. Left ventricular hypertrophy (LVG) according to the Sokolow index was found in 70.5% (96.9% males and 3.1% females) with p Conclusion: Many electrical and echocardiographic signs of cardiac adaptation were found in our sample and must lead to a closer follow-up of these trained footballers to avoid or prevent dramatic cardiovascular events.展开更多

They threaten the stability and mobility of the knee and can compromise walking and standing. These fractures are on the increase, especially affecting young and active subjects. Orthopedic treatment is a rare indication apart from non-displaced or slightly displaced forms. Surgical treatment is required in displaced forms, particularly in depression fractures. The aim of this work was to report the lesional and therapeutic aspects of tibial plateau fractures in our department. Patients and Method: Patients and method: This was a retrospective study over 36 months from January 2019 to December 2021. Included in this study were patients treated for a tibial plateau fracture in our department and followed up for at least 10 months. The epidemiological and clinical data analyzed were age, sex, affected side, etiology, mechanism of injury, pathological anatomy and associated lesions. The fractures were classified according to the classification of Duparc and Ficat. The slightly or non-displaced forms were treated orthopedically while the displaced forms were treated surgically. The minimum follow-up was 10 months. The results were evaluated by the anatomical criteria according to Mazas and Duparc and functional according to Merle d’Aubigné. Results: The authors collected 71 cases of tibial plateau fractures. They accounted for 4.0% of all limb fractures, 5.8% of lower limb fractures and 33.8% of knee fractures in our service. The male sex was the most represented at 78.9% with a sex ratio of 3.7. The age group of [20 - 40] years was the most affected, i.e., 53.5%. The average age was 41 years with extremes of 17 and 82 years. The left side was affected (n = 47) and the right side (n = 24). Road traffic accident was the main cause. The mechanism of injury was mainly represented by lateral and sagittal compressions. Lateral unituberosity and bi-tuberosity fractures were the most frequent pathological types in our series, respectively 42.2% and 28.2%. The associated lesions were mainly represented by bone, ligament, skin and neurological lesions. The treatment was orthopedic in 52.1% and surgical in 47.9%. According to the functional criteria of PMA, our results were very good and good at 77.4%, Average at 14.1% and poor at 8.5%. Conclusion: It appears in this study that fractures of the tibial plateaus are frequent and serious because of their articular nature. Lateral and sagittal compressions are the most evoked injury mechanisms. Lateral unituberosity and bituberosity fractures are the most frequent pathological types. Functional and anatomical results are significantly better with surgical treatment.展开更多

They are due to an ob-struction of the intestinal lumen by a solid mass of fruits or undigested vegetable fibers. They are seasonal (wild fruit season from March to June) in the Sahel Zone. We report a case of small bowel obstruction in a 35-year-old rural man after swallowing a significant amount of wild grapes (Lannea microcarpa). We proceeded to the resection of the occluded ileal segment and performed an ileal terminal ileal anastomosis. There weren’t any complications during the postoperative site.展开更多

文摘Introduction: Conjunctival granulomas are tumor pathologies of various origins. A foreign body, whatever its nature, is often involved in its genesis. To date, there is very little data on foreign body conjunctival granulomas, the prevalence would be approximately 10% and their underestimation is probably linked to the inconsistency of their clinical presentation. Patient and Observations: We report a case of conjunctival granuloma caused by a metallic foreign body that went unnoticed in a young boy, the interest of rigor on primary protection measures for high-risk occupations, and of the strict application of the diagnostic protocol relating to ocular trauma. Discussion: foreign body granulomas, despite their usually harmless nature, can jeopardize the anatomical and functional prognosis of the affected eye. Only a detailed interview and a meticulous clinical examination allow the diagnosis to be made and the distinction to be made with conjunctival granulomas of different causes. Conclusion: the possibility of the involvement of a foreign body in the genesis of conjunctival granulomas must impose the rigorous application of diagnostic and therapeutic protocols.

The Sigmoid Volvulus represented 7.8% of emergency surgery activities and 37.2% of intestinal obstruction. The male sex predominated with 98.57% against 1.43% of the female sex. The average age was 42.11 years old with limits of 18 to 70. The average deadline evolution was 2.53 days with limits of 1 to 3. The sigmoidectomy with immediate anastomosis was performed in 66% of patients, colectomy with 2-times anastomosis: according to Hartman 20% and Bouilly Volkman 11%, detorsion with colopexy 3%. The early morbidity rate was 5.71%. The average duration of hospitalization was 10.8 days with limits of 5 to 40 days. Two deaths were recorded. Conclusion: Sigmoid Volvulus is frequent in young adult sex male in Africa. We did not find any significant difference between the surgical technique and the advent of complications. The Colectomy with immediate anastomosis seems to be ideal to us that anytime the conditions are appropriate.
文摘Introduction: Urinary tract infection is a public health problem. Patients who have to undergo urology surgery are exposed to infectious complications if there is an untreated urinary tract infection. The objective of our study is to identify all the germs responsible for urinary tract infections discovered in the preoperative assessment of hospitalized patients with their susceptibility and antibiotic resistance profiles. Patients and Methods: This is a retrospective and descriptive study of 124 cases of cytobacteriological examination of urine collected over 2 years from January 1st, 2016 to December 31st, 2017, performed in the urology department of the University Hospital of Bocar S. Sall of Kati. The parameters studied were: age, sex, reason for admission, the diagnosis chosen, the result of the cytobacteriological examination of urine and the antibiogram. Results: We collected 124 cases of cytobacteriological examination of urine during this period. The average age of our patients was 58 years old with extremes ranging from 3 years to 84 years. The sex ratio was 6 in favor of men. 86 patients, or 69%, were admitted for micturition disorders. In 53.2%, the diagnosis was BPH followed by urolithiasis 22.6%. Cytobacteriological examination of urine identified 55 cases of urinary infection, 44%. In 34 cases or 60%, the germ responsible was an E. coli. Two germs were sensitive only to one antibiotic. Conclusion: This study made it possible to have an idea about the antibiotic susceptibility of germs involved in urinary tract infections. Awareness-raising for the proper use of antibiotics needs to be strengthened to minimize the risk of increasing antibiotic resistance.
文摘Background: A cardiovascular assessment is rarely performed among athletes despite more and more frequently reported fatal events. Most of these accidents are of cardiovascular origin. Moreover, data on ECG or Echocardiography are rare in our context justifying our study to assess electrical and echocardiographic pattern among high-level footballer in Bamako. Methods: It was a cross-sectional study conducted in Bamako from April 2015 to?March 2016 among high-level footballers aged 14 to 35 years old without distinction of sex with at least 10 hours weekly training since one year. The ECG and echocardiographies were recorded respectively with a 12-lead CONTEC and an ATL 5000 echocardiographic machine. Each ECG record was analyzed by a cardiologist in accordance with the Seattle 2013 criteria and those pathological reviewed by a second cardiologist according to the same criteria and definitively classified as normal (physiological) or abnormal ECG (requiring complementary explorations). A third cardiologist was associated in case of discordance of the first results. The collected data were inserted in a Microsoft Excel sheet and analyzed with SPSS version 20. Chi Square and Fisher statistical tests were used to compare our results. The significance level was set at 0.05. Results: We collected data of 227 top footballers with male sex represented in 90.3% giving a sex ratio of 3.04. Means for age, weight, height, body mass index (BMI) were respectively 22 years, 69.90 kg, 177.21 cm and 22.21 kg/m2. Sinus bradycardia was found in a proportion of 45.8% more represented in the age group of 30 and more years (p = 0.275). First-degree atrioventricular block (AVB) was present in 19.4%. Short PR was found in 0.4% of the sample. Left ventricular hypertrophy (LVG) according to the Sokolow index was found in 70.5% (96.9% males and 3.1% females) with p Conclusion: Many electrical and echocardiographic signs of cardiac adaptation were found in our sample and must lead to a closer follow-up of these trained footballers to avoid or prevent dramatic cardiovascular events.
文摘Objective: The aim of this study was to describe the epidemiological, clinical and Para clinical characteristics in patients hospitalized for pulmonary embolism in the cardiology department of Gabriel Toure University Hospital. Methodology: It was a retrospective and descriptive study from January 2011 to December 2014 and involved all patients hospitalized during the study period. Results: The study included 21 patients out of 1738 hospitalized patients, with a prevalence of 1.21%. The mean age was 38.57 years with extreme ages of 18 and 64 years. The sex ratio was 0.40. Risk factors found in the study were oral contraception (19.05%), overweight (19.05%), smoking (14.28%), HIV (4.76%) and heart failure (4, 76%). 61.90% (n = 13) had isolated pulmonary embolism, 38.09% (n = 8) had venous thrombosis and pulmonary embolism association. Through the chest angio-CT, 28.57% of obstructions were located at the left branch of the pulmonary artery, 9.52% at the right branch and 61.90% were bilateral obstructions. Four deaths were recorded, all in a context of massive pulmonary embolism, with a fatality rate of 19.05%. Conclusion: Pulmonary embolism is a serious and common disease, often difficult to diagnose. It is a cardiovascular emergency and requires immediate and adequate care.
文摘The publication of the use of an inflatable penile prosthesis （IPP） in 1973 by Dr. FB Scott. changed the world of treatment options for erectile dysfunction （ED）. Much has been written since then about techniques, improvements, management of difficult cases, complications and their management, and mechanical and device changes over time. Few reports, if any, are available in the medical literature regarding the early development, surgical techniques, and controversies surrounding its introduction to the world＇s urological community. This article is, for the most part, the observations of one who was ＂there＂ in the early and mid 1970＇s and was a witness to the history of this remarkable marvel of creativity, engineering, design, and to the personalities involved.
文摘Introduction: Tibial plateau fractures are solutions of continuity of the epiphyseal-metaphyseal block of the upper end of the tibia of which at least one line enters the joint. They threaten the stability and mobility of the knee and can compromise walking and standing. These fractures are on the increase, especially affecting young and active subjects. Orthopedic treatment is a rare indication apart from non-displaced or slightly displaced forms. Surgical treatment is required in displaced forms, particularly in depression fractures. The aim of this work was to report the lesional and therapeutic aspects of tibial plateau fractures in our department. Patients and Method: Patients and method: This was a retrospective study over 36 months from January 2019 to December 2021. Included in this study were patients treated for a tibial plateau fracture in our department and followed up for at least 10 months. The epidemiological and clinical data analyzed were age, sex, affected side, etiology, mechanism of injury, pathological anatomy and associated lesions. The fractures were classified according to the classification of Duparc and Ficat. The slightly or non-displaced forms were treated orthopedically while the displaced forms were treated surgically. The minimum follow-up was 10 months. The results were evaluated by the anatomical criteria according to Mazas and Duparc and functional according to Merle d’Aubigné. Results: The authors collected 71 cases of tibial plateau fractures. They accounted for 4.0% of all limb fractures, 5.8% of lower limb fractures and 33.8% of knee fractures in our service. The male sex was the most represented at 78.9% with a sex ratio of 3.7. The age group of [20 - 40] years was the most affected, i.e., 53.5%. The average age was 41 years with extremes of 17 and 82 years. The left side was affected (n = 47) and the right side (n = 24). Road traffic accident was the main cause. The mechanism of injury was mainly represented by lateral and sagittal compressions. Lateral unituberosity and bi-tuberosity fractures were the most frequent pathological types in our series, respectively 42.2% and 28.2%. The associated lesions were mainly represented by bone, ligament, skin and neurological lesions. The treatment was orthopedic in 52.1% and surgical in 47.9%. According to the functional criteria of PMA, our results were very good and good at 77.4%, Average at 14.1% and poor at 8.5%. Conclusion: It appears in this study that fractures of the tibial plateaus are frequent and serious because of their articular nature. Lateral and sagittal compressions are the most evoked injury mechanisms. Lateral unituberosity and bituberosity fractures are the most frequent pathological types. Functional and anatomical results are significantly better with surgical treatment.
文摘Introduction: Oral mucositis (OM) can have a significant impact on patients’ quality of life, pain and treatment costs. Almost all patients receiving head and neck chemoradiation develop OM. Patients and Methods: Twenty patients were evaluated retrospectively for OM when undergoing head and neck chemoradiation. The control, soda/salt rinse, was compared to a powdered supersaturated calcium phosphate rinse (SSCPR), SalivaMAX. Results: The SSCPR group experienced a delay in the onset of OM, which was not statistically significant, and a marked reduction in peak OM that was statistically significant (p > 0.001). Conclusion: This retrospective study demonstrates that a powdered SSCPR is a safe and effective method of oral mucositis mitigation.
文摘Bowel occlusions by bezoars are rare pathologies. They are due to an ob-struction of the intestinal lumen by a solid mass of fruits or undigested vegetable fibers. They are seasonal (wild fruit season from March to June) in the Sahel Zone. We report a case of small bowel obstruction in a 35-year-old rural man after swallowing a significant amount of wild grapes (Lannea microcarpa). We proceeded to the resection of the occluded ileal segment and performed an ileal terminal ileal anastomosis. There weren’t any complications during the postoperative site.
