This study seemed to determine the pattern and features of vertebral fractures in black African women which may be useful for comparisons with the pattern of worldwide populations.
I. Objective: to highlight the clinico-MRI prole of lumbar disc herniation on sciatic lumboradiculgia in bi- river hospital settings (cases of Kinshasa and Brazzaville). This was aII. Materials and methods: retrospective, documentary and multicenter study of 302 patients who performed lumbar MRI examinations in 18 months in hospitals in Kinshasa and Brazzaville. The mean age of patients was 53.4 years. The most represented age groupIII. Results: was 50 to 59 years old. The female sex was predominant (55.4%) with a ratio of 0.79. The majority of patients (68.2%) came from Kinshasa. Lumboradiculalgia was the most predominant indication with (49.3%), followed by low back pain (48%). The majority of MRI examinations (91.4%) were performed without injection of contrast product. T1 and T2 weightings were performed in 100% of patients. Diseased disc degeneration was found at (41.7%) and lumbar disc herniation at (27.2%). The MRI examination was normal in (47%) of the patients. Based on potentially clinically positive relevance, only 48.7% of our MRI diagnoses were clinically positive. Age (p=0.000), lumboradiculalgia (p=0.000) and specialist physician prescription (0.039) had a statistically signicant relationship with clinically positive diagnosis. HDL is a pathological reality in the hospitals ofIV. Conclusion: Kinshasa and Brazzaville. The MRI prole found mainly corroborates the observations of the literature. Lumbar disc herniation and degenerative disc disease remain the most frequently encountered pathologies on magnetic resonance imaging in hospitals in Kinshasa and Brazzaville. They are at the origin of the lumbar spinal syndrome and affect the young population. The posterolateral disc herniation remains the most frequently encountered subtype with predominance of damage to the oors: L4-L5 and L5-S1.
Background and Objective: Chronic obstructive pulmonary disease (COPD) is predicted to be the third leading cause of death worldwide by 2020. Its diagnosis remains a challenge in developing countries such as DRC, with the use of Gold standard, spirometry, limited. Chest imaging plays an important role in orientation. The absence of local radiological data from COPD had therefore motivated this study. The aim of this study is to establish a relationship between gender, environment and COPD. Materials and Methods: Retrospective and analytical study of clinical and thoracic imaging data (radiography and CT scan), collected from the records of 120 COPD subjects followed in three Kinshasa medical trainings between January 2014 and June 2017. Fisher's test compared the results obtained. The combination of imaging data and clinical phenotype through Pearson chi-square testing, logistic regression and odds-ratio (OR). The service threshold was set at 0.05. Results: the study population (average age of 64.52±6.82 years) was predominantly male (78.3% n=94). Results: the study population (average age of 64.52±6.82 years) was predominantly male (78.3% n=94). The proportions of sputum were more common in men than in women, the difference being statistically significant. Indeed, the male sex confers a triple risk (OR=3.1; IC 95% 1.2-8; P=0.015). Women were more exposed to domestic and/or occupational pollution (65.4% n=17; than men were (26.6% n=25). Indeed, the male sex conferred a risk of exposure to domestic pollution and/or occupational pollution multiplied by 14 times (OR=14.3; IC 95%; 2-100; P=0.001) and allergy conferred a risk of exposure to domestic pollution by 17 times (OR=17.1; IC95%: 2.1-137, p=0.007). Conclusion: This study showed the male sex and allergy is conferred a high risk of the domestic pollution or occupation pollution.
<p><strong><em>Introduction:</em></strong><em> </em><em>HIV-Associated Nephropathy </em><em>may shorten the life expectancy of affected patients. Its </em><em>early detection is beneficial for the indication of treatment and hence prevention of progression to the end-stage of renal failure. The final diagnosis requires renal biopsy which may be difficult in some African area; clinical and ultrasound criteria may be helpful. The aim of this study was twofold: to characterize renal sonographic changes in HIV-positive patients with HIV associated Nephropathy and to investigate the correlation between renal sonographic changes and histological lesions in central Africa.</em></p><p><strong><em>Methods:</em></strong><em> A prospective and multi-center study conducted from January 2013 to July 2015 included, for renal ultrasound evaluation of the length, thickness and echogenicity, forty two of the 334 biologically confirmed HIV-positive patients who presented with significant proteinuria suggestive of HIV associated Nephropathy. And transcutaneous renal biopsy with histopathology has been performed in 16 patients of them. </em><em>Statistical analyzes were used.</em></p><p><strong><em>Results:</em></strong><em> There were 100 men and 234 women; proteinuria was positive in 42 patients, (12.6%). The average length of the kidneys was 111 ± 8 mm (normal), with 10% of patients with pathological values (5% with kidneys of reduced size and 5%, increased size). The kidneys had an average thickness of 44 ± 5 mm (normal), with 21% of patients presenting an increase in renal thickness. Quantitative echogenicity was calculated at 1.492 ± 0.793 (normal), with 79% of patients with increased quantitative echogenicity. Of the 16 patient</em><em>s</em><em> biopsied, all had tubulo-interstitial lesion</em><em>s</em><em>, and 75% of them associated with glomerular le</em><em>s</em><em>ion</em><em>s</em><em>.</em><em> </em><em>In simple correlation analysis, tubular dilatation was positively and significantly related to quantitative echogenicity (r = 0.67, p < 0.01) and to renal parenchyma thickness (r = 0.67; 0.85, p ? 0.05). The relationship between the other parameters studied did not reach statistical significance. In multiple linear regression, glomerular hyalinosis, glomerular proliferation, tubular dilatation, tubular atrophy, interstitial fibrosis, and interstitial inflammation emerged as the main determinants of quantitative echogenicity; however, the relationship was statistically significant only for tubular dilatation (? = 0.305, p = 0.034).</em><em></em></p><strong><em>Conclusion:</em></strong><em> The present study showed the characteristic of renal change and the relation with histology found in central Africans patients.</em>
