Outcomes after emergency abdominal surgery in COVID-19 patients at a referral center in Brazil.

PURPOSE: COVID-19 is associated with high morbidity and mortality in patients undergoing surgery. Contrary to elective procedures, emergency operations should not be postponed. We aim to evaluate the profile and outcomes of COVID-19 patients who underwent emergency abdominal surgery. METHODS: We performed a retrospective analysis of perioperative data of COVID-19 patients undergoing emergency surgery from April 2020 to August 2020. RESULTS: Eighty-two patients were evaluated due to abdominal complaints, yielding 22 emergency surgeries. The mean APACHE II and SAPS were 18.7 and 68, respectively. Six patients had a PaO2/FiO2 lower than 200 and more than 50% of parenchymal compromise on chest tomography. The most common indications for emergency surgery were hernias (6; 27.2%). The median length of stay was 30 days, and only two patients required reoperation. Postoperatively, 10 (43.3%) patients needed mechanical ventilation for a mean of 6 days. The overall mortality rate was 31.8%. CONCLUSION: Both postoperative morbidity and mortality are high in COVID-19 patients with respiratory compromise and abdominal emergencies.

Estimate of age through the analysis of x-ray of third molar and hand and wrist: case reports

The Forensic Anthropology and Forensic Dentistry, in one of its branches, aim to base skills making possible to estimate the age period for an individual, through factors such as tooth mineralization and bone development. This paper aims to report on two cases from Scientific Expertise Center - Renato Chaves, Belém- PA, where two individuals after committing crime, were referred to under 18s without supporting documents. Through data collected in the archives of the Scientific Expertise Center, an analysis of the mineralization of the teeth were made, highlighting the third molars by panoramic radiography; as well as the study of bone development of the hands and wrists of individuals through radiographs. After, the analysis was compared to surveys conducted by Nicodemos, Moraes and Médici-Filho, befitting the chronology of mineralization of permanent teeth among Brazilian citizens together with the work of Greulich-Pyle, Radiographic correlation concerning the chronology of the development of the hand and wrist. As a result of the analysis, it was obtained, for case 01, an estimated age of 17; and for case 02 the estimated age was between 18-19 years.
