Anxiety and depression after mild head injury: a case control study.

Abstract Objectif The aim of this study was to investigate psychiatric comorbidities (depression and anxiety) associated with acne in dermatology in Lomé (Togo). Material and methods We conducted a case-control study between July 2017 and February 2018. Each case was matched to two controls by sex and age (± 5 years). The ECLA grid was used for the clinical evaluation of acne, and the GAD-7 and PHQ-9 questionnaires were used for respective screening of anxiety and depression. Results We recruited, with their consent, 900 subjects including 300 patients and 600 matched to two controls according to sex and age (± 5 years). The mean age of the cases was 23.7±5.7 years and that of the controls was 23.6 ± 6.2 years, with no difference between the two groups (p = 0.9362). The overall severity score for acne according to the ECLA grid ranged from 2 to 28 points. The severity of acne was not correlated with anxiety scores (GAD-7: r = -0.02; p = 0.6724) and depression (PHQ-9: r = 0.11; p = 0.0567). The GAD-7 questionnaire allowed us to note 72 cases of anxiety (24%) among our patients and 37 cases among our controls (6.2%). The mean GAD-7 score in the cases was 6.5±4.9 compared with 2.9±3.8 in the controls (p <0.0001). Similarly, the PHQ-9 questionnaire allowed us to detect 92 cases of depression (30.7%) among our patients and 82 cases of depression among our controls (13.7%). The average of the PHQ 9 score in the cases was 7.2 ± 5.2 versus 4.0 ± 4.7 in the controls (p <0.0001). Conclusion: Depression and anxiety are significantly associated with acne, regardless of severity. It is important to look for them in any patient admitted for acne, for a psychological / psychiatric decision.

Abstract Background In Benin, motorcycles are the main means of transport for road users and are involved in more than half of crashes. This study aims to determine the effect of wearing a helmet on reducing head injuries in road crashes in Benin. Methods This case-control study nested in a cohort took place in 2020 and focused on road trauma victims. The sample, consisting of 242 cases (trauma victims with head injuries) for 484 controls (without head injuries), was drawn from a cohort of traffic crash victims recruited from five hospitals across the country from July 2019 to January 2020. Four groups of independent variables were studied: socio-demographic and economic variables, history, ²oural variables including helmet use and road-related and environmental variables. To assess the shape of the association between the independent variables and the dependent variable, a descending step-by-step binary logistic regression model was performed using an explanatory approach.. Results Fewer of the subjects with a head injury were wearing a helmet at the time of the crash 69.8% (95% CI = 63.6 - 75.6) compared to those without a head injury 90.3% (95% CI = 87.3 - 92.8). Adjusting for the other variables, subjects not wearing helmets were at greater risk of head injuries (OR = 3.8, 95% CI (2.5 - 5.7)); the head injury rating was 1.9 (95% CI = 1.2 - 3.3) times higher in subjects who were fatigued during the crash than among those who were not and 2.0 (95% CI = 1.2 - 3.3) times higher than in subjects with no medical history. Conclusion Failure to wear a helmet exposes motorcyclists to the risk of head injuries during crashes. It is important to increase awareness and better target such initiatives at the subjects most at risk.
