Facial dog bites in children: A public health problem highlighted by COVID-19 lockdown.

BACKGROUND: Stay-at-home injunction during COVID-19 pandemic led to new dynamics in households and increased the risk of domestic accidents involving pets. The aim of the study was to demonstrate an increase of facial dog bites in children during first lockdown period in France, compared to the same period in 2018 and 2019. Secondary objective was to investigate the demographics and circumstances in which dog bites occurred. METHODS: A retrospective multicentric study was conducted nationwide. Patients under 18 years old managed in fifteen oral and maxillofacial surgery departments for a dog bite were included. RESULTS: Eighty-seven patients were included. A significant increase of the number of children managed for facial dog bite was noticed in 2020 (p=0.0005). The male-to-female ratio was significantly reversed in 2020 with more bites in girls than boys (p=0.02). In 2020, children were mostly bitten to cheeks (28.6 %), lips-and-chin region (26.2 %), and eyelids (23.8 %). Severe bites increased in 2020, in comparison with 2018 and 2019. Dog bites occurring while petting or playing significantly increased in 2020 (31 %) (p=0.03). CONCLUSION: The process leading to bites is highly dependent on the balance of dog-owner relationship. This was strongly disrupted during COVID-19 pandemic, resulting in the increase of dog bites in households. Regarding dog bites, face is the most vulnerable area in children. Its injury has lots of esthetic and functional consequences and maxillofacial surgeons have a key role to play in their prevention. Reminders of some of these management and prevention strategies are presented in this article.

Self-Assessment Versus Peer-Assessment in Microsurgery Learning: A Comparative Retrospective Study in a Surgery Residents Cohort.

INTRODUCTION: In surgical learning, self-assessment allows the physician to identify and improve his strong and weak points. However, its scientific validity has yet to be demonstrated. The aim of this study was to analyze if there is a link between self-assessment accuracy and improvement in surgical skills. We make the hypothesis that an accurate self-assessment allows a greater improvement MATERIAL AND METHOD: We set up a retrospective cohort study at the tertiary University Hospital of Angers. Between 2019 and 2021, twenty-eight surgery residents took part into a microsurgery program and were included in the study. For two weeks, they performed anastomosis training on inert material and living anesthetized rats under microscope. Each resident was evaluated during the workshop by senior surgeons on 10 items: movement stability and fluidity, instrument manipulation, needles, dissection, clamp setting, vessel manipulation, suture, checking before clamp removal, checking after clamp removal, watertighness. Self-assessment was performed by the residents with the same grid, at the end of the workshop. Residents' and senior's evaluations were double-blind. We retrospectively analyzed the concordance between senior objective assessment and self-assessment, and the effect of an accurate self-assessment on technical improvement. RESULTS: Data for twenty-five residents were analyzed, 14 were female (56%). The mean age was 29 years. Surgical specialties were orthopedics (44%), maxillofacial surgery (45.4%), neurosurgery (12%), gynecology (4%) and vascular surgery (4%). According to Cohen's kappa coefficient, 14 residents (56%) underestimated themselves, 7 (28%) were concordant with peer-assessment and 4 (16%) overestimated themselves. The concordance between self and peer assessment during sessions was positive for the most objective items, and negative for the most subjective items. Technical skills improvement in term of peer-assessment averages was positive for each item in each group, without statistical differences between groups. CONCLUSION: We found that the ability to self-assess in a fast-track microsurgery module for surgery residents varied according to analyzed gestures. We demonstrated an improvement in term of self-assessment for objective items, and a decrease for subjective items. However, we didn't find any relation between improvement curve and the accuracy of self-assessment.

Masseter muscle pressure injury: First report of a prone position complication in patients with COVID-19.

We report the case of a 59-year-old, obese woman who underwent prolonged prone position during the medical management of an acute respiratory distress syndrome induced by SARS-CoV-2 infection, complicated by a masseter muscle pressure injury. Such side effect may be underestimate in intensive care units and should be prevent by prophylactic dressings on facial weight-bearing sites. The understanding of facial deep tissue injury is essential to guide clinical detection and management of such a complication in COVID-19 patients.
