Introduction: Total hip prostheses are a reliable means of treating hip disorders. It is indicated when pain and reduced mobility of the hip become incompatible with the patient’s daily activities. In low-income countries, the risk factors for hip disease are numerous, but the means for its management, such as total hip prostheses, are not. The aim of this work was to determine the morbi-mortality of total hip prostheses in the short and medium term in our department and to review the literature. Patients and Method: This was a prospective and descriptive study over a period of 9 years. It involved 50 THPs performed on 45 patients. Patients who had received a THP and were followed up for at least two years were included. We excluded patients who were lost to follow-up. The Moore-type posterolateral minimally invasive approach was used. Complications were investigated from the immediate postoperative period and in the medium term. The final functional results were evaluated according to the Postel Merle d’Aubigné score. Results: We performed 50 THPs out of 750 procedures, i.e. , 6.6%. The indications were: primary coxarthrosis 60%, necrosis of the femoral head 26%, post-infectious balloon hip 4%, and pseudarthrosis of the femoral neck 10%. The average time to the consultation was 2.4 years with extremes of 1 and 5 years. According to the terrain, sickle cell disease represented 18%, tuberculosis 12%. Postoperative complications were lameness 12%, dislocation 6%, suppuration 6%, death 4%, peri-prosthetic fracture 8%, loosening 2%, peri-articular ossification 2%, and paralysis of the external popliteal nerve 2%. Conclusion: Whoever performs a THP is obliged to monitor the patient as long as he/she is alive. Complications are possible at any time and can negatively change the assigned goal and force the surgeon to be expensive and sometimes inconclusive secondary interventions.

引用

Open Journal of Urology 2014年第9期4卷 115-120页

作者： lamine Niang Charles Kouka Yoro Diallo Médina Ndoye Racine Kane mohamed Jalloh Abdoulaye Ndiaye Issa Labou Jeanne Diaw Sérigne M. Gueye General Hospital of Grand Yoff Dakar University Dakar Senegal Health UFR Thies Senegal

Primary tumors of the upper urinary tract are rarely reported in the literature. We thus report here four cases of primary tumors of the upper urinary tract that were difficult to diagnose, in three women and one man. Preoperative diagnosis was established in only two cases requiring a nephro-ureterectomy. The other two cases were surprisingly diagnosed during anatomopatho- logical examination. Preoperative diagnosis was a pyonephrosis in one case and a renal failure resulting from stenosis of the pelvic ureter in the other. Despite modern methods, primary tumors of the upper urinary tract remain difficult to diagnose.

Objective: To report our experience of the esophageal plasty for caustic stenosis of the esophagus. Methods: Retrospective study of caustic stenosis of the esophagus in patients aged over 15 years, operated in Ouagadougou from 2008 to 2016. Nine patients were operated. Patients ranged in age from 25 to 53 years. Caustic ingestion was voluntary in 6 cases. Psychiatric disorders were confirmed in one case. The type of surgery and the postoperative evolution were analyzed. Results: In 6 patients the plasty was preceded by a gastrostomy or a feeding jejunostomy. The transplant, always placed in retro sternal position, was colic in 8 cases and gastric in one case. The evolution was marked by the occurrence of a cervical fistula in 5 cases, postoperative peritonitis in 2 cases, parietal suppuration in 2 cases and pneumothorax in 3 cases. One case of death was noted. After a follow-up of 6 months to 9 years, we noted a case of dysphagia. Conclusion: Esophageal plasty is a saving gesture that restores normal nutrition to the patient. It deserves to be promoted.

Introduction: Arterial hypertension (AH) during pregnancy is defined as systolic blood pressure greater than or equal to 140 mm Hg and/or diastolic blood pressure greater than or equal to 90 mm Hg on two (2) successive visits separated by at least 4 hours in a woman who has been at rest for 10 to 15 minutes in the seated position and then in the left lateral decubitus position. The aim of this study was to determine the prevalence and types of arterial hypertension among pregnant women in the maternity ward of the CMC les Flamboyants. Methods: This was a prospective descriptive study lasting six (6) months, from 1 October 2021 to 31 March 2022, of all pregnant women and/or parturients admitted to the maternity ward of the CMC les Flamboyants with a resting blood pressure (BP) greater than or equal to 140/90 mm Hg during the study period. Results: During the study period, we recorded 707 cases of pregnant and/or parturient women, 50 (7.07%) of whom were hypertensive. The average age of the patients was 29 years, with extremes of 18 and 41 years. The 20 - 29 age group was the most affected, with 26 cases (52%). Headache, dizziness and oedema of the lower limbs were constant in all cases. The risk factors for arterial hypertension were dominated by familial hypertension in 19 cases (38%), multiple gestures in 17 cases (34%) and a history of gestational hypertension in 16 cases (32%). Gestational age between 28 and 36 weeks’ amenorrhoea was the most common, with 20 cases (40%). Type I hypertension was most common on admission, with 34 cases (68%), followed by type II hypertension, with 8 cases (16%). Pre-eclampsia was the most frequent maternal complication with 27 cases (54%) followed by eclampsia with 15 cases (30%). Fetal distress was the most frequent fetal complication, 19 cases (38%), followed by death in utero 9 cases (18%). Conclusion: Compliance with consultation programmes and correct patient follow-up could help reduce maternal-foetal complications.

Open Journal of Pediatrics 2023年第6期13卷 791-797页

作者： Bangoura Kaba Kolie Ouo-Ouo Camara Salematou Hassimiou Bangoura M’mah Aminata Camara Emmanuel Diallo mohamed lamine Diallo Fatoumata Binta Diop Mamadou Moustapha Kouyate Moustapha Beimy Pé Pediatrics Department CHU Donka Conakry Guinea Gamal Abdel Nasser University of Conakry Conakry Guinea Institute of Nutrition Conakry Guinea

The objective of this case report was to highlight the characteristics of posterior urethral valves observed in a 3-year-old patient and to describe their management. The case of a 4-year-old patient treated for a posterior urethral valve with bilateral renal cortical atrophy was reviewed. The diagnosis was confirmed by abdominal ultrasound, cystography and abdominal CT. He was referred to Martinique (a tertiary health establishment) for effective support. From the acute situation to the fortuitous discovery, its understanding must be deepened because of the potential immediate symptomatic impact in the form of renal colic which can be associated with sepsis, as well as in the long term on renal function. This observation is intended to help the attending physician to initiate his diagnosis and treatment.

We report the case of a 28-month-old male child with no particular history who was admitted to the emergency room for severe abdominal pain associated with vomiting, asthenia and fever at 39.1˚C that had progressed for 4 days. He was conscious, polypneic at 32 cycles/min on admission. On palpation the abdomen was distended, painful as a whole, more pronounced in the epigastrium. There was abdominal contracture, generalized defense, a cry with sudden decompression of the umbilicus. On abdominal auscultation, there was a disappearance of prehepatic dullness, a decrease in the dullness of the flanks and absence of hydro-aeric noises. On the digital rectal examination, Douglas’s cul de sac was bulging and sensitive. An unprepared X-ray of the abdomen revealed diffuse grayness, lateral gas crescent pneumoperitoneum under diaphragm. The preoperative resuscitation consisted of the placement of a nasogastric tube, a urinary catheter, a peripheral venous route and the fluid electrolyte rebalancing adapted according to the blood ionogram, early antibiotic therapy with broad aero and anaerobic spectrum. Surgical management under general anesthesia found at laparotomy a perforation of the anterior surface of the duodenal bulb which we estimate to be 1 cm in diameter with fibrin deposits. The gesture was the toilet of the peritoneal cavity;suture of the bank and the operative consequences were simple.

Dieulafoy’s Lesion of the Duodenum: The Management of This Unusual Location

引用

Case Reports in Clinical Medicine 2022年第7期11卷 268-272页

作者： Rajae Bounour Amal Mejait Maria Lahlali Asmae lamine Hakima Abid Hakima Abid Amine Mekkaoui Mounia Elyousfi Dafrallah Benajeh mohamed El Abkari Sidi Adil Ibrahimi Nada Lahmidani Hepato-Gastroenterology Department CHU Hassan II Fez Morocco

Dieulafoy lesion (DL) is a rare source of gastrointestinal tract bleeding that can affect any site of the gastrointestinal tract, particularly the stomach and less commonly the duodenum. Early endoscopy during a bleeding episode is essential for an accurate diagnosis and sometimes multiple endoscopies are needed to establish the diagnosis. In this report, we describe a case of duodenal DL detected and treated by endoscopy. We report the case of a 65-year-old patient admitted for massive upper gastrointestinal bleeding due to a Dieulafoy lesion of the duodenum. Endoscopic diagnosis and treatment were possible and hemostasis was achieved by injecting adrenaline and placing 3 clips. Various effective endoscopic techniques are available to control bleeding, the combination of injection therapy and mechanical therapy reduces the risk of recurrence.

We report the case of a 39-year-old patient with a history of chronic gastritis, functional colopathy and appendectomy, referred by another public institution for severe abdominal pain. He had been admitted 6 days previously for nausea, vomiting, diarrhea, fever, asthenia since the onset of dyspnea with 89% desaturation in ambient air and a dry cough. A diagnosis of gastroenteritis was made and treated without success. The appearance of abdominal distension and bloating motivated his transfer to the CTPI where the rRT-PCR was carried out positive and an X-ray of the abdomen without preparation which had demonstrated a significant aerocoly with agglutination of handle. Surgical management under general anesthesia found a clean cavity after coeliotomy, multiple intestino-intestinal, intestino-parietal and omentum-parietal adhesions. The gesture consisted of an adhesiolysis, omentectomy. The postoperative follow-up was favorable with resumption of transit on D5 postoperative. Put under the COVID-19 treatment protocol, the rRT-PCR was negative on D13, output on D14 and removal of the D19 files without postoperative complications.
