作者： Abdullallahi Bello Galadima Lukman Olalekan Ajiboye Muhammad Nuhu Salihu Isha Nurudeen Orthopedics and Trauma Department Usmanu Danfodiyo University/Teaching Hospital Sokoto Nigeria Department of Orthopaedics and Trauma University of Abuja Abuja Nigeria Orthopedic Department National Orthopaedic Hospital Dala Nigeria

Background: Fractures of humeral shaft in adults are common injuries. Humeral shafts non-union either from late presentation after initial treatment by traditional bone setters or failed non-operative orthodox care is a major problem in this part of the world. This non-union is a major treatment challenge with increased cost of care and morbidity in this part of the world. Humeral shaft non-union can be treated with locked intra-medullary nailing (LIMN) or dynamic compression plating (DCP). Study on comparison of these methods of fixation in this part of the world is scarce in literature search, hence the reason for this study. Objective: The objectives of this study are: (1) to compare early clinical outcome following fixation of humeral shaft fracture nonunion with DCP versus LIMN;(2) to compare the time of radiologic fracture union of DCP with LIMN;(3) to compare complications following fixation of humeral shaft fracture nonunion with DCP versus LIMN. Patients and Methods: This was a randomized control study done for 2 years in which fifty adult patients with humeral shaft non-union were recruited. The patients were grouped into 2 (P = DCP & N = LIMN). Forty five of the patients completed the follow up periods of the study and then analyzed. The P group had ORIF with DCP while the N group had ORIF with LIMN. Both groups had grafting with cancellous bones. Each patient was followed up for a period of 6 months at the time which radiographic union is expected. Any patient without clinical and/or radiographic evidence of union after six months of surgery was diagnosed as having recurrent non-union. The data generated was analyzed using SPSS Version 23. The results were presented in charts and tables. The paired t-test was used while considering p value Result: Forty five patients completed follow up. There was a male preponderance (4:1), right humerus predominated (3:2). Motor vehicular accidents were the commonest cause of the fractures (62%). Most non-union fractur

Background and Objective: Hepatocellular carcinoma (HCC) is a public health problem due to its high incidence and high mortality rate. The epidemiology and prognosis of this disease is poorly documented in Bouake. The aim of the study was to describe the epidemiological aspects and identify the predictors of death in patients hospitalized for HCC in the Internal Medicine Department of the Bouake University hospital in order to improve patient management. Material and Methods: We conducted a cross-sectional study from 1 January 2020 to 31 December 2022 in the Internal Medicine Department of Bouake University hospital, involving 160 patients. Results: The prevalence of HCC was 3.6%, the mean age was 48.86 ± 14.5 years with extremes of 14 and 90 years and the sex ratio was 2.90. Viral hepatitis B was observed in 81% of patients, with HBs Ag positivity in 71.2%. The performance status of WHO was ≥ 2 in 93.2% of cases. HCC was discovered at advanced stage respectively in 51% for BCLC C and 47.8% for BCLC D stage. The nodules were multiple (89.3%), and superior to 3 cm. The hospital mortality was 20% and BCLC D stage of HCC was significantly associated with death (p = 0.04) in the univariate analysis. The BCLC D stage of HCC was significantly associated with death. Length of stay inferior to 5 days (OR = 0.77;CI 95: 0.61 - 0.96) and hepatic encephalopathy (OR = 1.39;CI 95: 1.10 - 1.77), were the two independent predictors of mortality. Conclusion: HCC mainly affected young men infected with chronic viral hepatitis B. Short length of stay and hepatic encephalopathy were independent predictors of mortality.

Background: The choice of the appropriate operative intervention in patients with late and neglected hip fracture continuous to be a huge dilemma for orthopedic surgeons. Purpose: To evaluate the satisfaction or otherwise of some treatment options using the modified Harris-hip score (HHS) in resource poor setting. Materials and Methods: A retrospective cross-sectional study conducted at ATBUTH, Bauchi. Data of 60 patients over the age of 18 years with hip fractures (femoral neck, intertrochanteric and sub trochanteric fractures) who had operative intervention between 1st September 2019 and 31st August 2020 with cannulated screws, Proximal femur lock compression plate (PFLCP), cementlessor cemented bipolar hemiarthroplasty (BHA). Results: The mean age of studied patients was 65.7 ± 16.1 years, with age ranging from 19 - 101 years. M:F ratio was 1.2:1 across all age groups and 1:1.4 amongst those >60 years. 51 patients (85%) presented > 1 week after injury with 24 patients (40%) sustaining hip fractures from low energy trivial indoor fall and 28 patients (46.7%) mostly younger sustaining fractures from high energy motor vehicular accident (MVA). The prevalence rate for femoral neck, intertrochanteric and subtrochanteric fractures were 32 (53.3%), 17 (28.3%) and 11 (18.3%) respectively. From the data retrieved, 21patients (35.0%), 17 patients (28.3%), 20 patients (33.3%) and 2 patients (3.3%) had PFLCP, cemented BHA, cementless BHA and cannulated screw fixation respectively. Most (66.7%) of those who had PFLCP achieved satisfactory radiologic union and there was also 94.1% and 85% satisfactory outcome rate amongst the patients with cemented BHA and cementless BHA respectively. Irrespective of the operative intervention method at 1 year follow-up, there was a statistically significant improvement in post-operative HHS (P value 0.02), with 83.4% having good to excellent results. Conclusion: There is highrate of late and neglected hip fracture in our environment. Satisfac

Introduction: Human immunodeficiency virus (HIV) is a major public health problem with high morbidity and mortality among children. The objective of this work was to audit the deaths of children and adolescents with HIV infection followed up in the pediatric department of the Regional teaching hospital of Borgou/Alibori (CHUDB/A) the from 2005 to 2020. Patients and Method: This was a retrospective and descriptive study conducted in the pediatric department of CHUD/B-A in Parakou. All children with HIV infection who died from January 1, 2005 to August 31, 2020 were included. Data collection was carried out in three stages: a phase of medical records processing, a phase of community survey and a phase of death audits. The variables studied were sociodemographic, clinical, biological, therapeutic and evolutionary. Results: Over the study period, the data of 464 infected children were recorded, including 92 deaths, representing a case fatality rate of 19.83%. Severe acute malnutrition (69.23%), gastro-intestinal tract infections (43.58%) and serious opportunistic pulmonary infections (24.36% pulmonary tuberculosis and 19.23% pneumocystis) were the main causes of death. The main dysfunctions found were: the delayed diagnosis of HIV infection (79.35%), the absence or delay in consultation when the child’s clinical condition deteriorates (32.61% and 47.83%), delayed initiation of antiretroviral treatment (42.39%) and non-adherence to treatment (38.04%). Non-adherence to treatment was predominant in adolescents (90.49%). Conclusion: Specific interventions for early detection, adequate nutritional care, psychosocial support for adolescents and mothers of children are necessary to reduce mortality due to HIV among children and adolescents.

Introduction: The initial global response to the SARS-CoV-2 pandemic focused on adults as adolescents mainly had subclinical infections. Adolescents, however, could transmit the virus and hence be a risk to the elderly, young children and immunocompromised. Adolescents are also at risk of long-term complications. This study sought to determine the prevalence of antibodies to SARS-CoV-2 among adolescents in Southern Nigeria, and to determine the association between SARS-CoV-2 seropositivity and age, gender, socioeconomic class, school type and nutritional status. Methods: This descriptive cross-sectional study was carried out in Edo state of southern Nigeria. We recruited 270 in-school adolescents aged 10 - 19 years. A WHO-adapted, pre-tested questionnaire was used to obtain data on participant history and risk factors. The questionnaire was interviewer-administered. Adolescents whose parents gave consent were recruited through a multi-stage randomized sampling method. Capillary blood for the assay was collected and analysed using a lateral-flow immunoassay device. The primary outcome was serostatus of the study. The positive predictors of serostatus were finally determined using a multiple logistics regression model. Statistical significance was set at p Results: The seroprevalence of SARS-CoV-2 was 45.9%. IgM antibodies were found in 5.6% of participants. Older adolescents had higher seropositivity rates than younger adolescents (2 = 8.101, p = 0.017). There was no association between gender and seropositivity. Adolescents in public schools were more likely to be seropositive than those in private schools (2 = 25.242, p = 0.001). A higher seroprevalence was noticed among study participants in the lower socioeconomic class (x2 = 6.928, p = 0.031), and those in overcrowded classes. (2 = 79.303, p = 0.001). Conclusion: This study showed a high seroprevalence of SARS-CoV-2 among in-school adolescents. Behavioural change communication on SARS-CoV-2, vaccination of adole

Introduction: Post-blast tympanic perforations represent an entity of traumatic perforations;various mechanisms are at the origin of the latter, and the increase in conflicts and acts of violence are increasing the studies on this subject, but few data are available in our context. Objective: This paper aims to study post-blast tympanic perforations in Yaounde, specifically the epidemiological, clinical, and paraclinical aspects. Methodology: We conducted a descriptive cross-sectional study with retrospective and prospective data collection in six Yaounde hospitals over 63 months from January 1, 2018, to March 31, 2023. All patients with at least one post-blast tympanic perforation were included. Socio-demographic, clinical and paraclinical data were collected on a questionnaire and analysed using SPSS 28 software. Results: We included 124 patients. The prevalence of post-blast tympanic perforations was 0.1% of the consultations in the departments. 71 The average age was 28.6 ± 9.1 years, with extremes ranging from 7 to 49 years. The median consultation time was five days. The most frequent injury circumstances were physical aggression (81.45%) and armed conflict (10.5%). The injury mechanisms were slaps (75%), punches (21.74%) and grenades (4.8%). The main symptoms on admission were hearing loss (63.7%), tinnitus (58.1%) and otalgia (57.3%). The tympanic perforations were unilateral in all cases, the anterior-inferior location was more characteristic, and the deafness was conductive in 58.3% of cases, followed by mixed deafness in 23.3% of cases. Conclusion: Post-blast tympanic perforations are rare in consultation. The population is primarily male and from the second decade of life. The main circumstance is aggression.
