Abstract

IntroductionOccupational exposure to organic solvents can have multiple health effects for exposed employees.Neuropsychic effects represent an important part of these effects and have a significant impact on patients’ ability to workObjectives-To describe the socio-professional and medical characteristics of workers exposed to organic solvents-To screen among the study population for neuropsychological effects related to an organic psychosyndrome using the Q16 questionnaire.MethodsA retrospective descriptive study of workers exposed to organic solvents, who were referred to the occupational medicine department of Charles Nicolle Hospital in Tunis for a medical assessment of their fitness for work over the period from 2016 to 2022. The socio-professional data were collected from the medical records. The Swedish Q16 questionnaire in its French version was used to screen for neuropsychological signs of organic psycho-syndrome.ResultsA total of 37 workers were included. The mean age was 45.38 ± 8.63 years with a clear male predominance (77%). The mean occupational seniority was 21.39 ± 11.11 years. The average duration of the occupational exposure to organic solvents was 18.25 ± 11.29 years. The most represented sectors of activity were the plastics industry (11%), the automotive industry (19%), the carpentry sector (14%) and the aeronautics sector (9%). Our population was represented by polyvalent workers in 49% of cases and by painter in 24% of cases. Psychiatric history was noted in only one case. The main functional signs reported by the workers were wheezing dyspnea with breathing difficulties (13%) and headaches (11%).The Q16 questionnaire was found to be positive in 65% of the cases, with a higher rate of positivity for the items relating to unusual fatigue (73%), irritability for no particular reason (67%), short memory (64%) and headaches (58%). Acquired dyschromatopsia detected by a Lanthony test was found in 39% of the cases, 23% of which was associated with a positive Q16 questionnaire. Additional exploration by specific psychotechnical tests was carried out in five cases, all of which came back positive with significant attentional and cognitive impairment.A declaration of an occupational disease according to the Table n°23 (Halogenated derivatives of aliphatic hydrocarbons) and Table n°40 (other liquid organic solvents for professional use) of the Tunisian list of occupational diseases eligible for compensation was made in three and two cases respectively. A definitive exemption from exposure to organic solvents was indicated for all workers with a positive Q16 questionnaire.ConclusionsExposure to organic solvents is a risk encountered in various occupational sectors. Thus, education of the employees to the dangers encountered with a reinforcement of the collective and individual technical protection means are essential in order to avoid their detrimental effects on health.Disclosure of InterestNone Declared
