Purpose The aim of this study was to determine the real influence of bariatric surgery on the clinical evolution of patients infected with SARS-Cov-2 in the postoperative period. Methods We conducted a retrospective analysis including two groups of patients: those who presented COVID-19 before bariatric surgery and those who presented it within 3 months of postoperative. Primary outcome was related to the severity of COVID-19, measured by the following variables: presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation. Laboratory markers for inflammatory response, glycemic status, and micronutrients were analyzed as secondary outcomes. Results From the 222 individuals operated on within the study period, only 66 (29.7%) presented COVID-19, 42 (18.9%) in the preoperative period and 24 (10.8%) after the procedure. Mean age was 36.3 ± 9.5 years and mean preoperative BMI was 39.9 ± 4.2 kg/m 2 . There were no statistically significant differences between the groups regarding symptoms presentation (92.9% × 87.5%, p = 0.66), need for hospitalization (11.9% × 16.7%, p = 0.713), ICU admission (4.8% × 4.2%, p = 1.000), and invasive ventilation (2.4% × 0.0%, p = 1.000). Regarding the quantitative variables, absolute lymphocyte count was significantly lower in the group who presented COVID-19 after surgery (1822.9 ± 482.2 × 2158.6 ± 552.9, p = 0.035). Conclusion Patients who had COVID-19 before and after sleeve gastrectomy did not differ with statistical significance for the presence of symptoms, need for hospitalization, ICU admission, and invasive ventilation.

Purpose to outline the clinical and laboratorial profile of patients with obesity undergoing bariatric surgery who presented positive reverse transcription-polymerase chain reaction (RT-PCR) for severe acute respiratory syndrome coronavirus-2 (Sars-CoV-2) in the preoperative period without symptoms presentation. Methods Case series of 17 patients undergoing bariatric surgery who presented positive RT-PCR for Sars-CoV-2 in the preoperative period, with no reported symptoms. Data collected included demographic characteristics, length of hospital stay, waiting time for surgery, inflammatory markers, serum levels of micronutrients and dengue virus (DENV) serology. Results In total, 219 patients underwent bariatric surgery in our institution during the study period. The incidence of asymptomatic cases was 7.7%. The sample comprised 88.2% of women, with mean age of 39.3 years and mean preoperative body mass index (BMI) of 37.7 kg/m2. Thirty five percent of the sample had previous diagnosis of diabetes and 29.4% had hypertension. The mean time elapsed between positive RT-PCR and the operation was 17 ± 7.5 days and the mean length of postoperative hospital stay was 1.9 ± 0.43 day. Mean lymphocytes count was 2,409.7/mm3 and the mean platelet-to-lymphocyte ratio was 126.3. Mean C-reactive protein value was 5.8 mg/dL, while ferritin marked 107.4 µg/L. DENV IgG was identified in all patients who tested for it. Mean levels of vitamin D and zinc were 25.6 ng/mL and 79.9 µg/dL, respectively. There were no postoperative complications reported. Conclusion None of the included patients presented any of the laboratory markers related to disease severity. Moreover, it is important to notice that all patients who tested for DENV, had the specific IgG detected in their serum. Graphical abstract
Introdução: A cirurgia parendodôntica é uma alternativa ao tratamento endodôntico convencional, principalmente em casos envolvendo lesões perirradiculares associadas a processos osteolíticos, em que a terapia endodôntica convencional ou seu retratamento não obtiveram sucesso. Novos métodos terapêuticos têm ganhado espaço na clínica odontológica para esse tipo de caso, entre os quais se destaca a fibrina rica em plaquetas e leucócitos, que, ao concentrar e permitir uma liberação mais prolongada dos fatores de crescimento, promove uma modulação do processo reparador. Esse processo é baseado na otimização da regeneração tecidual através da inserção da membrana de fibrina. Objetivo: O objetivo do presente trabalho é apresentar, por meio do relato de um caso clínico, a utilização de fibrina rica em plaquetas e leucócitos em cirurgia parendodôntica, com intuito de reparo ósseo. Resultados: O acompanhamento clínico e tomográfico foi realizado após 190 dias, momento no qual foi constatada ausência de sintomatologia, bem como completo reparo da lesão e restabelecimento do osso cortical vestibular, além de ausência de lesão detectável em tomografia. Conclusão: No caso clínico relatado, houve uma completa regeneração tecidual da área envolvida na lesão.
Penetrating orbitocranial trauma caused by foreign bodies requires prompt intervention. Nasal endoscopic approach is a less invasive technique. We describe an unusual case of a large skull base wooden penetrating foreign body submitted to this approach, in which a septal cartilage graft was used to reconstruct the medial orbit wall.
