Introduction: Work related musculoskeletal disorders (WRMSDs) are currently one of the leading causes of disability worldwide. However, information on their prevalence and associated factors remains insufficient in Cameroon. Objective: Determine the prevalence and associated factors of WRMSDs among the staff of the University of Dschang (UDs). Methods: We conducted a descriptive cross-sectional study from 05 February to 18 March 2020 during which a modified Nordic Musculoskeletal Questionnaire (NMQ) was administered face-to-face with participants. A convenient type non-probability sampling was used for the selection of participants. The data collected were analyzed with EPI info 7.2.2.6. A bi-variate analysis was conducted to determine factors associated with WRMSDs. Results: We enrolled 425 participants. The 12-month prevalence of WRMSDs was 93.88%. Almost half of the participants (49.18%) were prevented from their normal activities due to WRMSDs in the past 12 months. The most affected body region was the lower back with a prevalence of 71. 53%. The occurrence of WRMSDs at the UDs was significantly associated with: stress (P<0.01; OR=5.96); intense physical exertion (P<0.01; OR=3.45) and repetitive movements (P<0.01; OR=2.98). Conclusion: UDs staff is a high-risk population for WRMSDs. It is imperative to protect this human capital by preventing and treating WRMSDs.
Background: Clubfoot is a birth defect found in about 1000 live births yearly in Cameroon and its treatment is often associated with relapses. The objective of this study was to evaluate treatment outcomes with the Ponseti’s technique and factors associated with relapses. Methods: We conducted a 5-year retrospective study on clubfoot children at the Bafoussam Baptist Healthcare Center (BBHC). Data on age, sex, birth setting, previous treatment, pirani scoring, number of casts and follow-ups, bracing and relapse were recorded in case report forms. Data were analyzed with SPSS: 25 software; bivariate analysis was performed to determine factors associated with relapse. Results: This study enrolled 78 clubfoot children with median age, 12 months (IQR1,24), 44 (56.4%) had undergone previous treatment elsewhere. The mean Pirani score before treatment was 4.9 [±SD: 0.9] for the left foot (LF), and 4.9 [±SD: 1] for the right (RF). The average number of casts performed was 6.5 [±SD: 1.5]. Tenotomy of the Achilles tendon was performed in 54 (69.2%) children. The mean final Pirani score was 0.9 [±SD: 0.5] for the LF and 0.8 [±SD: 0.6] for the RF. Only 5 (6.4%) cases did not wear Iowa braces and loss of sight rate was 1.3% (1/78). The relapse rate was 9.1% (7 /77). Treatment requiring >8 casts was associated with relapse (aOR: 10.35; CI [1.05-101.55]; P=0.04). Conclusion: The Ponseti’s technique is effective in the treatment of CTEV in the West region of Cameroon. Treatment requiring more than 8 cats is a risk factor for relapse.
