Extrapulmonary localizations are a reason for hospitalization in our health facilities. The objective of this study was to describe the epidemiological, clinical, paraclinical and evolutionary aspects of extra pulmonary tuberculosis (EPT) at the Abass Ndao Hospital Center. Patients and Methods: This was a descriptive cross-sectional study conducted over a period of 11 years (January 1, 2010 to December 30, 2021). All patients with extrapulmonary tuberculosis hospitalized in the department of internal medicine during the recruitment period were included. Results: Fifty-two (52) patients were collected. The year 2019 recorded the most cases 23.08% (n = 20). The mean age of the patients was 40.56 ± 18.24 years. The age group 20 - 34 years 42.31% (n = 22) was the most represented. Females were in the majority 61.54% (n = 32) with a sex ratio (M/F) was 0.63. Housewives were in the majority 40.38% (n = 21). 60.87% of the cases (n = 14) came from a health facility. 38.46% of the cases had been infected. 21.74% (n = 9) were smokers. The reasons for consultation were dominated by fever (67.44%), AEG (62.79%) and cough (41.86%). Eighteen patients (40.91%) had fever. The mean time to consultation was 77.37 ± 90.3 days with extremes of 3 and 365 days. The median was 45 days. More than half of the patients 61.90% (n = 26) had anemia. Positive retroviral serology was noted in 21.43% of cases. All patients had a CRP greater than 6. More than half of the patients 51.92% (n = 27) had multifocal tuberculosis. The peritoneum 44.23% (n = 23) was the main organ affected. The average hospital stay was 9.8 ± 4.9 days with extremes of 1 and 19 days. All patients had received the protocol in force at the national level. Death was noted in 4 patients (9.52%). Conclusion: EPT is characterized in our context by a notorious diagnostic difficulty due to the multiplicity of clinical presentations, the complexity of explorations, and the problems of differential diagnosis notably with other granulomatosis, systemic lupus and cancers. This difficulty is reflected in the low rate of diagnosis with a paraclinical argument of certainty and in the long diagnostic delays.展开更多

Throughout the world, 287 cases of Rhupus have been described. We report two new observations of two patients who presented predominantly distal erosive polyarthritis with positive anti-Sm antibodies in one case and SmRNP in the other case. Observations: Case 1: 37 years old patient, with a recent diagnosis of pulmonary tuberculosis. She has since 8 months an inflammatory, bilaterally and symmetrical polyarthralgia without deformation or ankylosing synovitis, associated with malar erythema without other abnormalities. Immunological tests showed: positive Rheumatoid factor at 158 IU/ml, positive Anti-CCP at 550 IU/ml, and positivity of antinuclear at 1/1280 nuclear fluorescence with a strong presence of anti-Sm >8 IU/ml. The diagnosis of rhupus was concluded, without serious visceral involvement. Case 2: A 28-year-old patient, married with 3 children, with bilateral, symmetrical, deforming and chronic polyarthritis affecting large and small joints, which had been evolving for over 5 years without cutaneous abnormality associated. Paraclinical investigations showed: a biological inflammatory syndrome. Immunology was positive, with rheumatoid factors at 78 IU/ml, anti-CCP at 561 IU/ml, antinuclear antibodies at 1/1280 with positive anti-SmRNP and anti-SSA/Ro52, and a positive direct Coombs test. Joint ultrasound revealed tenosynovitis of the extensors and common flexors of the fingers, erosions and synovitis of multiple PPIs. The diagnosis of rhupus was based on the presence of 10 ACR criteria for RA and 8 ACR/EULAR 2019 criteria for SLE. Conclusion: Rheumatoid arthritis is a rare autoimmune disease combining features of both systemic lupus erythematosus and rheumatoid arthritis in the same patient, often sequentially. Despite a growing number of case reports and series, a consensus on the classification of SLE arthritis is still lacking, and diagnostic criteria for rhupus do not exist. These cases of rhupus must be recognized, as the vital and/or functional prognosis may be different from SLE alone or isolated RA.展开更多

We evaluated risk factors for depression and anxiety in an autoimmune disease cohort compared with diabetic patients. Patients and Methods: We conducted an observational, cross-sectional, case-control survey comparing two groups: individuals with connective tissue disease (CTD) and diabetic controls who were followed within three Dakar University hospitals during the period from April to June 2023. Results: The sample comprised 106 participants, of whom 51 (48%) had CTD and 55 (52%) served as diabetic controls. In the CTD group, the majority had lupus (19) and rheumatoid arthritis (23). The CTD patients had a mean age of 41.0 years (SD 16.9), while the diabetic patients had a mean age of 55.9 years (SD 11.7), with a significant difference observed (p Conclusion: Compared to a chronic disease, devastating in Africa and evolving over the long term, autoimmune diseases are more strongly and more frequently associated with anxiety and depression. This is a factor to be taken into account in the holistic management of these patients.展开更多

The objective was to characterize its epidemiological and clinical aspects, as well as its therapeutic modalities in Senegal. Methodology: this was a multicenter, retrospective, descriptive and analytical study carried out from the Senegalese register of pituitary adenomas (2008-2022). Results: 242 patients were collected with an average age of 42.4 ± 13 years and a sex ratio (M/F) of 0.91. The mean consultation time was 19.7 ± 23 months. The circumstances of discovery were pituitary apoplexy (11 cases, 4.54%), tumor syndrome (176 cases, 72.72%), gonadal manifestations (103 cases, 42.56%), dysmorphic syndrome (21 cases, 8.68%), hypercorticism (15 cases, 6.19%). Morphologically, it was a macroadenoma (197 cases, 81.40%), an extensive adenoma (22 cases, 9.10%). The hormonal profile was lactotropic hypersecretion (80 cases, 33.05%), somatotropic (13 cases, 5.39%), corticotropic (14 cases, 5.78%), mixed (9 cases, 3.71%). The factors significantly associated with prolactinoma were young age (p = 0.000), female sex (p = 0.000), long consultation delay (p = 0.000) and microadenoma (p = 0.001). Only arterial hypertension was associated with acromegaly (p = 0.000). We found a significant correlation between Cushing’s disease and microadenomas (p = 0.000). Non-secreting adenomas were significantly associated with advanced age (p = 0.000), long delay in consultation (p = 0.000), male gender (p = 0.000), tumor syndrome (p = 0.001) and macroadenomas (p = 0.000). Pituitary surgery was effective in 173 patients (71.49%) including 166 cases (68.59%) by transphenoidal approach. Postoperative incidents were transient diabetes insipidus in 82 cases (47.39%), cerebrospinal fluid leak (20 cases, 11.56%). Death was observed in 18 patients in the entire series (7.44%). The latter had a tumor syndrome (88.88%), a macroadenoma (83.33%) and had undergone pituitary surgery (72.22%). Conclusion: pituitary pathology has become a reality with clinical and secretory polymorphism. The diagnostic delay explains the predominance of macroadenomas which are sources of pre and post-operative complications.展开更多

Despite their altered appearance, the X-Ray diffractions show mineral paragenesis: Quartz-Kaolinite-Illite and an important amorphous phase. On the Ternary Keil-Rankin diagram for the CaO-SiO2-Al2O3 the volcanic tuffs of Mako area are situated between pozzolan and the fly ash. The difference between silica and lime is greater than 34% in these volcanic tuffs. In this study, they have been mixed with Portland cement to obtain pozzolanic cements respectively with 20%, 30%, 35% and 40% of addition of volcanic tuffs. The pozzolanic reactivity is highlighted by the compressive strength increase until 90 days of conservation in water. It supposes that the vitreous phase of the volcanic tuffs reacts with the free CaO (CaOf) of Portland cement to produce new hydrated minerals. This study has a positive economic and environmental impact. Because the time of grinding of pozzolanic cements is reduced. Also, the addition of volcanic tuffs reduces the production of clinker, then the CO2 emission.展开更多

To achieve these objectives, a geotechnical characterization of the tuff samples was carried out and the geopolymerization stabilization was adopted for the manufacture of bricks. These bricks stabilized by an alkaline activation offer compressive strengths that exceed the threshold value (2.9 MPa) set by the standard (NF P14-304). The best compressive strengths (12.14 MPa) and flexural tensile strengths (5.43 MPa) are obtained in the series of bricks made with 35% of the mass of a solution of caustic soda at 12 molars concentration with a curing temperature cooking of 185°C and an average absorbance of 13.21%.展开更多
