Impact of biomechanical exposure (job-exposure matrix 'MADE') and social support on return to work following occupational injuries.

OBJECTIVES: To identify the determinants that influence the outcome of the return to work (RTW) after occupational injuries. METHODS: We conducted a cross-sectional study at the National Health Insurance Fund of Tunisia among victims of occupational injuries. Individual and professional factors have been evaluated through a face-to-face questionnaire for ten months. Biomechanical exposure was estimated by the job-exposure matrix "MADE" and social support by the Social Support Scale. Along with descriptive statistics, we used bivariate analysis, binary logistic regression, and random forest. RESULTS: We included 199 injured workers aged 20-60 years (mean = 42.73; 79.9 % male).Of the 199 injured workers, 39.7 % had unsuccessful RTW. Low social support, biomechanical exposure, blue-collar workers, working long hours, and severe injuries were associated with an unsuccessful return to work. In the variable importance plot issued from the random forest model, low social support at work was the most important risk factor of an unsuccessful RTW, followed by MADE variables: repetitiveness and effort. CONCLUSION: Biomechanical exposure and social support are main influencers of the return-to-work process.

Plasma Exchange for Lyme Neuroborreliosis delayed diagnosis: A case report.

Lyme neuroborreliosis (LNB) is a rare infectious disease, caused by Borrelia burgdorferi spirochetes and responsible for a variety of neurological manifestations. The most common manifestations of LNB in children are cranial nerve involvement, especially facial nerve palsy often accompanied by lymphocytic meningitis. In this article, we present a case of a 4-year-old boy presented to our emergency department with abdominal pain evolving for a week and symmetrical ascending progression of weakness responsible for severe respiratory failure. Diagnosis of Guillain-Barré syndrome (GBS) was initially suspected. Although our patient had received 2 courses (each of 5 days) of Intravenous immunoglobulin (IVG) treatment, no clinical improvement was observed. The diagnosis of LNB was confirmed by detection of both IgG and IgM specific antibodies in serum. The patient's muscle weakness got better after a 2- week course of Ceftriaxone but respiratory muscle failure didn't improve with two extubation failures. Consequently, we decided to conduct plasmapheresis procedures. We managed to extubate the child and discharge him after a good recovery of his symptoms. Pediatricians must consider LNB disease in the differential diagnosis of GBS, especially when the patient didn't recover after IVG treatment. This case shows that plasmapheresis could be effective for pediatric neuroborreliosis cases with severe neurological disorders.
