Introduction: Acute obstructive renal failure (AORF) is a frequent clinical situation, secondary to obstruction of the urinary excretory tract. Whatever the cause, urinary tract obstruction suddenly opposes glomerular filtration and is responsible for tubulointerstitial lesions. It accounts for 10% of acute renal failure (ARF). The aim of this study was to identify the causes and prognosis of cases of acute obstructive renal failure managed at the Centre National d’hémodialyse Donka. Material and Methods: This was a prospective descriptive study lasting 6 months, from September 1, 2022 to February 29, 2023. All patients undergoing haemodialysis for acute obstructive renal failure who agreed to participate in the study and whose medical records were complete were included. Results: During the course of the study, we registered 97 haemodialysis patients, including 20 cases (20.62%) of acute obstructive renal failure. The mean age of the patients was 57.8 ± 10.54 years, with a male predominance of 11 cases (55%) and a sex ratio of 1.22. The reasons for consultation were dominated by physical asthenia 11 cases (55%), lumbar pain 9 cases (50%), vomiting 6 cases (30%) and acute urine retention 6 cases (30%). Arterial hypertension 16 cases (80%) and urinary tract infection 10 cases (50%) were the most common antecedents. The etiologies of RAOI were dominated by lithiasis 10 cases (50%), neoplasia 6 cases (30%) and benign prostatic hypertrophy 3 cases (15%). mean creatinine was 1267.60 ± 710.76 μmol/l with extremes of 243 μmol/l and 2822 μmol/l, mean urea was 39.56 ± 18.36, hyperkalemia in 14 cases (70%) and hyponatremia in 8 cases (40%). After hemodialysis, 9 cases (45%) recovered renal function, 4 cases (20%) became chronic and 7 cases (35%) died. Conclusion: The frequency of AKI remains non-negligible in our department, and early detection and prompt management would considerably reduce the morbidity and mortality associated with this pathology.

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.

The purpose of this study was to investigate the etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population. The clinical data of 142 patients with chronic pancreatitis were retrospectively studied. All patients were of Chinese nationality and hospitalized from January 2008 to December 2011. Their ages ranged from 14 to 76 years, with a mean of 43 years. Of 142 patients, there were 72 cases of obstructive chronic pancreatitis（50.70%）, 19 cases of alcoholic chronic pancreatitis（13.38%）, 14 cases of autoimmune pancreatitis（9.86%） and 37 cases of undetermined etiology（26.06%）. Pathologically, the average inflammatory mass diameter was 3.8±3.3 cm, biliary obstruction occurred in 36 cases, gall stones in 70 cases, calcification in 88 cases, ductal dilatation in 61 cases, side branch dilatation in 32 cases, ductal irregularity in 10 cases, lymphocytic inflammation in 23 cases, obliterative phlebitis in 14 cases, extra pancreatic lesion in 19 cases and fibrosis in 142 cases. Location of pancreatic lesion in the region of head（n=97）, neck（n=16）, body（n=12）, tail（n=15） and whole pancreas（n=2） influenced the choice of surgical procedures. Ninety-four patients（66.20%） received surgical treatment and 33.80% received other treatments. After operation, 80.85% of 94 patients experienced decreased pain, and 8.51% of 94 showed recovery of endocrine function but with a complication rate of 12.77%. All the operations were performed successfully. According to the pain scale of European Organization for Research and Treatment of Cancer（QLQ-C30） a decrease from 76±22 to 14±18 was observed. Etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population vary from others.

Pyothoraxes, also called thoracic empyemas, are defined by the presence between the two layers of the pleura, of a frankly purulent liquid, or of a shady or clear liquid but containing a majority of altered polynuclear cells with germs direct examination. They are said to be traumatic when they follow a thoracic trauma whatever the mechanism;usually a pre-existing post-traumatic pleural effusion. The general objective of this study was to help identify the epidemiological and prognostic factors in the management of post-traumatic pyothorax in the Thoracic Surgery Department of the Donka National Hospital. Methodology: This was a descriptive retrospective study covering a period of 2.5 years from 01/06/2016 to 31/12/2018 carried out in the Thoracic Surgery Department of the Donka National Hospital. Results: During the study period, 17 cases of post-traumatic pyothorax were observed among the 288 files of admitted and hospitalized patients. In the course of this study, a rate was 5.90%. The most affected age group was 1 to 5 years old. The male sex was in the majority (76.5%). The most common occurrence was the fall, i.e. 41.2%. 47% of patients consult after 60 days. Chest pain and dyspnea were the main symptoms during our study (82.3%). Antibiotics and analgesics dominated the medical treatment used in 100% of the cases and pleural drainage was the first line surgical treatment practiced in 88.2% of the cases. The prognosis is favorable without sequelae in 52.9% of cases with an average hospital stay of 9 days. Post-traumatic pyothorax is a serious

Over the past decades, cancer has become one of the toughest challenges for health professionals. The epidemiologists are increasingly directing their research efforts on various malignant tumor worldwide. Of note, incidence of cancers is on the rise more quickly in developed countries. Indeed, great endeavors have to be made in the control of the life-threatening disease. As we know it, pancreatic cancer（PC） is a malignant disease with the worst prognosis. While little is known about the etiology of the PC and measures to prevent the condition, so far, a number of risk factors have been identified. Genetic factors, pre-malignant lesions, predisposing diseases and exogenous factors have been found to be linked to PC. Genetic susceptibility was observed in 10% of PC cases, including inherited PC syndromes and familial PC. However, in the remaining 90%, their PC might be caused by genetic factors in combination with environmental factors. Nonetheless, the exact mechanism of the two kinds of factors, endogenous and exogenous, working together to cause PC remains poorly understood. The fact that most pancreatic neoplasms are diagnosed at an incurable stage of the disease highlights the need to identify risk factors and to understand their contribution to carcinogenesis. This article reviews the high risk factors contributing to the development of PC, to provide information for clinicians and epidemiologists.
