Introduction: The uncontrolled management of waste electrical and electronic equipment (W3E) causes respiratory problems in the handlers of this waste. The objective was to study the stains associated with respiratory symptoms in W3E handlers. Methods: The study was cross-sectional with an analytical focus on W3E handlers in the informal sector in Ouagadougou. A peer-validated questionnaire collected data on a sample of 161 manipulators. Results: the most common W3E processing tasks were the purchase or sale of W3E (67.70%), its repair (39.75%) and its collection (31.06%). The prevalence of cough was 21.74%, that of wheezing 14.91%, phlegm 12.50% and dyspnea at rest 10.56%. In bivariate analysis, there were significant associations at the 5% level between W3E repair and phlegm (p-value = 0.044), between W3E burning and wheezing (p-value = 0.011) and between W3E and cough (p-value = 0.01). The final logistic regression models suggested that the burning of W3E and the melting of lead batteries represented risk factors for the occurrence of cough with respective prevalence ratios of 4.57 and 4.63. Conclusion: raising awareness on the wearing of personal protective equipment, in particular masks adapted by W3E handlers, favoring those who are dedicated to the burning of electronic waste and the melting of lead could make it possible to reduce the risk of occurrence of respiratory symptoms.

Introduction: Low back pain is nowadays a real public health problem in companies. The objective of the study was to determine the prevalence and factors associated with chronic low back pain among workers of a mining company in Burkina Faso. Material and Methods: This was a descriptive and analytical cross-sectional study with a retrospective collection that took place from August 1, 2021 to March 16, 2022 in a gold mine in Burkina Faso. It focused on mine workers who participated in the 2019 annual medical visit. Results: Out of a total workforce of 880 workers who took part in the annual medical visit in 2019, 165 had chronic common low back pain, i.e. a prevalence of 18.75%. The average age of low back pain workers was 37.21 ± 7.5 years. Among the workers suffering from low back pain, 62 (37.58%) held the position of machine operator. Clinically, mechanical pain was found in 113 low back pain workers (76%) and twenty-nine (17.58%) had radicular pain. Standard radiography of the lumbar spine was abnormal in 129 workers (78.18%. In the univariate analysis, the factors associated with the pathology were sex, level of study, work station and seniority in the position. After a logistic regression, the factors associated with its occurrence were whole-body vibration (Fisher’s test = 12.7541;P = 0.000), male sex (Fisher’s test = 8.363;P = 0.004), and seniority for 4 to 5 years (Chi2 = 4.0234;p = 0.046). Conclusion: The study reveals the existence of chronic low back pain cases among the workers of the mining company. There is a predominance of the pathology in men, workers exposed to vibrations and those with a seniority of 4 to 5 years. It is necessary to establish a policy of prevention of low back pain for the benefit of workers, in particular those exposed to vibrations.

Introduction: Violence is a major problem in today’s workplace. It affects workers in all sectors of activity. The aim of the study was to determine the prevalence and factors associated with violence among primary and secondary school staff in Ouagadougou. Materials and Methods: This was a cross-sectional, descriptive and analytical study that took place from April 22, 2020 to February 18, 2021 in primary and secondary schools in Ouagadougou. It focused on the educational staff of these establishments. Results: A total of 362 agents took part in the study. The average age of participants was 36.5 ± 6.89 years. The sex ratio was 1.62 men to one woman. The majority of workers were teachers, with 300 participants (82.87%). The average job tenure was 7 years ± 6.91 years. With regard to violence in the workplace, 87 workers were victims, representing a prevalence of 24.03%. Of these workers, 59 (67.81%) were men and 36 (41.38%) had less than six years’ experience. Acts of violence were predominantly pushing observed in 15 workers (50%), while shouting and aggressive tone dominated psychological violence and concerned 54 cases (36.24%). On univariate analysis, the factors associated with violence were age (p = 0.046) and type of establishment (p = 0.012). On multivariate analysis, only the nature of the establishment was the only factor associated with the occurrence of violence among teaching staff (OR = 2.3690, p = 0.0213). Conclusion: The prevalence of violence is high in these educational establishments. Age and type of establishment are factors associated with its occurrence. It is therefore necessary to develop an effective strategy for preventing this risk in the workplace.

Introduction: Occupational dermatitis has long been an unforeseen consequence of industrial progress. Today, most occupational diseases are dermatosis throughout the world. The morbidity and the various prejudices concern different actors, especially those of the cashew industry in Bobo-Dioulasso to Burkina Faso. We considered it appropriate to conduct this study in women who handle cashew nuts in the cashew nut shelling station at a factory. The aim is to contribute to the search for preventive and curative solutions adapted to this health risk. Methods: This was a prospective cross-sectional study with a descriptive purpose in May 2016. The study involved 112 women present in the factory in the shelling unit and having given their approval during our visit. This station is occupied by 118 women. Results: The prevalence of all dermatosis and dermatitis was estimated respectively at 98.21% and 88.39%. The manual shelling station with a shearing machine was exclusively occupied by illiterate women (72.3%) without personal protective equipment, with an average age of 33.74 ± 8.49 years. Among the clinical forms of contact dermatitis, the erythematous contact dermatitis was most observed (86.4%), followed by palmar keratoderma (70.9%), nail disorders (33.6%) and chemical burns (30%). The implication of Cashew Nut Shell Liquid (CNSL) was established with identified promoting factors. Aesthetic damage related to hand injuries had a significant psychosocial impact in 97.32% of cases. Discussion: Few studies exist on dermatitis and the health impacts in the reality of cashew because they reach vulnerable subjects without social welfare and health protection. The cashew nuts shell contains a highly irritating brown oily liquid. Dermatitis occurs during contact with this oily juice. The international literature reports this corrosive effect throughout the history of the chain. Human factors, technical factors and work environment aggravate the situation and compromize workwo

Dried leaves of Eucalyptus camaldulensis were finely grinded and fractionated by sieving into four granulometric classes (355 μm). The obtained powder fractions were used for essential oil (EO) extraction by hydrodistillation and their phytochemical profile and in vitro antioxidant activities were evaluated. The mother powder (unsieved powder) was used for comparison. Particle size exerted a significant influence (p in vitro antioxidant properties of the EOs. Comparatively, the mother powder had the highest contents of α-pinene (55.6%), camphene (3.4%) and limonene (3.7%), while 1,8-cineole (26.6% and 22.4%), exo-fenchol (5.6% and 3.5%), α-campholenol (4.2% and 3.4%), L-trans-pinocarveol (5.5% and 2.7%), L-borneol (12.6% and 6.8%) and α-terpineol (16.4% and 7.6%) are the main compounds of EOs from the <100 μm and 100 - 200 μm fractions, respectively. The antioxidant activities of the EOs revealed higher radical-scavenging activities DPPH (90.62% and 7
