Low Back Pain Among Students of Medical University of Tunis.

OBJECTIVE: Low Back Pain (LBP) is the most common musculoskeletal disorder among working adults. It is one of the most prevalent complaints among students. Medical students are among those who are most exposed to this condition; due to stress, numerous hours of studying, and the sedentary lifestyle. Our study aimed to determine the prevalence and associated factors of LBP among the students of Tunis Faculty of Medicine and to assess its impact on student life. METHODS: This cross-sectional study was carried out on the Tunis Faculty of Medicine students. Data were collected through an online self-administered questionnaire. Sociodemographic, personal, and lifestyle characteristics were collected. LBP was assessed using the Nordic Musculoskeletal Health Questionnaire and Its impact using the Oswestry Disability Index (ODI). RESULTS: One hundred and forty-eight students were included. The mean age was 22.9 ± 2.3 years (19.64-38.21). The sex ratio was 0.29. According to the Nordic questionnaire, the point, annual and lifetime prevalence of LBP were 37.8%, 80.4%, and 90.5%, respectively. The mean ODI score was 10.32 ± 8.48 % (0-32). The ODI score was minimal in 87.3% and moderated in 12.7% of cases. The associated factors with LBP were: young age (p = 0.015), spending more than 4 hours in a sitting position (p = 0.059), second cycle of medical studies (p = 0.006), low screen projection in the amphitheater (p = 0.029) and poor layout of the amphitheatres (p = 0.000). The feeling of depression was significantly higher among LBP students (p = 0.018). In the multivariate analysis, the factors that remained statistically significant were the second cycle of medical studies (OR= 3.41), feeling of depression (OR = 3.7), and the belief in the responsibility for the poor layout of the amphitheaters in the genesis or maintenance of LBP (OR = 7.66). CONCLUSION: LBP in medical students is multifactorial across both personal and college-life domains.

Primitive pelvic bone hydatidosis: What an amazing extension.

Hydatidosis is an anthropozoonosis mainly encountered in pastoral areas. It mostly affects the liver, lung, and rarely the bone and the soft tissues. Skeletal involvement is usually secondary to visceral hydatidosis. We report a case of a 49-year-old man presenting with one-year history of a progressive left hip pain. On local examination, there was tenderness in the left gluteal region with reduction in the hip range of motion. Pelvic X-ray revealed an expansive bone destruction involving the left hemi pelvis without periosteal reaction. A magnetic resonance imaging showed multiple cystic lesions extending from pelvic bones to the gluteal region. The possibility of hydatid disease was raised, and hydatid serology test was positive. No visceral involvement was found by additional examinations investigations revealed visceral hydatidosis. Thus, the diagnosis of a primary bone hydatid disease was established. No surgical excision was possible, and the patient was put on Albendazole. Echinococcosis should be ruled out while dealing with progressive expansive bony lesions. Surgical management remains a challenge especially if the involvement is very extensive.

Asymptomatic vertebral fracture in Tunisian post-menopausal women at risk: prevalence and risk factors.

Data are still scarce regarding the prevalence and the associated factors of vertebral fractures (VF) in the North Africa and the Middle East region. In this study, VF were common in at risk Tunisian women with a prevalence of 26.19%. Lower total hip T-score, having severe back pain, and being physically inactive were independently associated with VF. INTRODUCTION: Vertebral fractures are related to a marked increase in morbidity and mortality and they are associated with a definite risk of subsequent fracture. Nevertheless, they remain underdiagnosed and little is known about their epidemiology in the African countries. In this first Tunisian study, we aimed to assess the prevalence and the associated factors of asymptomatic VF among at risk Tunisian post-menopausal women. METHODS: In this cross-sectional study, we included post-menopausal women without a previous diagnosis of VF and who were referred for bone mineral density (BMD) measurement. Each participant had had an extensive medical history investigation, a BMD assessment, and a vertebral fracture assessment (VFA) scan using a dual energy X-ray absorptiometry. VF were defined using Genant semi-quantitative method. RESULTS: Two hundred and ten post-menopausal women were included. The overall prevalence of VF was 26.19% and 9.52% of our participants had multiple VF. The prevalence of VF was significantly higher in older participants, those having a history of prior severe fragility fracture, or having at least one intrinsic fall. The percentage of low bone mineral density and osteoporosis were significantly higher in women with VF. After binary logistic regression analysis, severe back pain (OR = 3.016; 95% CI 1.304-6.974), regular physical activity (OR = 0.065; 95% CI 0.02-0.213), and total hip T-score (OR = 0.56; 95% CI 0.383-0.820) were independently associated with VF. CONCLUSION: VF are very prevalent among at risk Tunisian post-menopausal women and their incorporation in a clinical and densitometric tool might identify more effectively subsequent fracture.
