Contradictory results of the accuracy of b.o-chemical markers to predict the stage of fib.osis in b.ack African patients with chronic hepatitis b.(CHb. were previously pub.ished. We con-ducted a prospective cohort study to determine the diagnostic accuracy of aspartate ami-notransferase to platelet ratio (APRI), aspartate aminotransferase to alanine aminotransferase ratio (AAR), platelet count, age-platelet (AP) in-dex, and FIb.4 index for the prediction of sig-nificant fib.osis or cirrhosis in 117 b.ack African patients (median age: 38 years, males: 73 %) with CHb.not previously treated. Among them, 45 had significant fib.osis and 18 had cirrhosis using the METAVIR score system. Factors as-sociated either with significant fib.osis or cir-rhosis were determined in logistic multivariate analysis. Areas under receiver operating curve were assessed and compared for APRI, AAR, AP index, FIb.4 index and platelet count. Sensitivity, specificity, positive and negative predictive values were determined for each b.ochemical markers. Multivariate analysis showed that as-partate aminotransferase (p 1.1) and FIb.4 index (cut-off > 2.1) ruled out significant fib.osis with high specific-ity of 84.7 % and 86.1 % respectively and nega-tive predictive values of 78.2 % and 72.9 % re-spectively. More accurately, APRI (cut-off > 0.63) or FIb.4 index (cut-off > 1.26) ruled out cirrhosis with high sensitivity of 94.4% and 88.9% and high negative predictive values of 98.1% and 96.3% respectively. In conclusion, APRI and FIb.4 index are simple readily availab.e markers to exclude significant fib.osis or more accu-rately cirrhosis in b.ack African patients with CHb.

b.ckground: Acute intestinal invagination or intussusception is the most common ab.ominal surgical emergency in infants, b.t it can occur at any age. Performing an ultrasound scan at the slightest clinical suspicion contrib.tes to early diagnosis and therapeutic management. Ob.ective: To show the relevance of ultrasound in the therapeutic management of the child’s intussusception through a correlation b.tween the ultrasound diagnosis and the clinical and/or per operative diagnosis. Patients and Methods: It was a retrospective study of 24 cases from July 2017 to Septemb.r 2020 (30 months) in the Medical Imaging and Paediatric Surgery departments of Teaching Hospital of b.uaké. We included only patients from 0 to 15 years old who had digestive symptoms, an ab.ominal ultrasound scan. These patients were eligib.e for surgery. Data analysis was performed with Epi info 7 software. Results: Median age was 17.2 months [02 - 120]. Male gender predominated (83.3%). Clinico-b.ological data were dominated b. ab.ominal pain (79.2%), vomiting (75%) and rectorragies (33.3%), with Omb.edanne’s triad in 33.3% and hyperleukocytosis (70.8%). Ultrasonography showed invaginated coves (95.8%) sitting in the right angl iliac fossa, peri-umb.lical and right flank in 73.9%. Cockade image coupled with the sandwich image accounted for 95.6%. Superficial adenopathies (45.8%) and peri-lesional fluid effusion (20.8%) were associated with it. An occlusive syndrome complicating intussusception was ob.erved in 41.67% associated with intra-peritoneal effusion of fluid (25%). There was a significant diagnostic agreement b.tween the clinic, ultrasound and surgery according to the Fisher’s exact test (p = 0.002). That b.tween ultrasound and surgery was calculated at 95.4%. Conclusion: This study allowed us to show a good clinical-echo-surgical concordance. Ultrasound is therefore an undeniab.e diagnostic, prognostic an

Introduction: Musculoskeletal injuries are common in children b.t rarely severe. Their treatment varies according to the type of injury ob.erved. The aim was to describ. the epidemiological and therapeutic aspects of severe musculoskeletal injuries in children during play. Patients and Methods: This was a retrospective descriptive study conducted in the Orthopaedic-Traumatology Department and the Paediatric Surgery Unit of the University Hospital of b.uaké b.tween January 2018 and Decemb.r 2020. It concerned patients less than 16 years of age hospitalised for more than 24 hours for a musculoskeletal trauma following a gamb.ing accident. The variab.es studied were epidemiological and therapeutic. Results: A total of 53 patients were collected. The frequency was 2.9%. The mean age was 9 ± 3.99 years. There were 38 (71.7%) b.ys and 15 (28.3%) girls. The sex ratio was 2.5. The patients were attending school in 79.3% (n = 42). The circumstances of occurrence were dominated b. falls during play accidents (n = 35;66%). Footb.ll was ob.erved in 93.5% (n = 49). The thoracic limb.(n = 35;66%) was the preferred site of these injuries. The injuries were closed (86.7%) with a predominance of forearm fractures (n = 22;41.6%). The average hospital stay was 2.8 ± 1.4 days. Most of the patients were treated orthopedically (n = 37;69.9%). The evolution was favourab.e without complications. Conclusion: Musculoskeletal injuries during play were infrequent (2.9%). The circumstances were dominated b. falls during play. The injuries were mainly closed fractures, most of which were treated orthopedically.
