RESUMEN
Objectives: The optimal management of perforated appendicitis remains controversial. Many studies advocate for antibiotics and an interval appendectomy whereas others suggest that performing an appendectomy at the time of presentation decreases post-operative morbidity. Confounding this argument further are the patients who fail non-operative management and end up requiring surgery during their initial hospitalization. This study aims to determine if early operative intervention should be considered for perforated appendicitis. Methods: This was a retrospective review of all patients who underwent an appendectomy (both laparoscopic or open) for perforated appendicitis between 2015 and 2020 at our institution. Results: A total of 271 patients met inclusion criteria for this study. Of this group, 250 patients underwent an immediate appendectomy whereas the remaining 21 patients underwent a trial of non-operative management and eventually required an appendectomy during their initial admission. When comparing the immediate versus delayed operative groups, there were no differences in demographic data including age and gender, and no differences in various imaging findings including AAST Grade IV or V appendicitis. Operatively, patients in the delayed group had a longer operative time (83.1 ± 32.9 vs. 64.1 ± 26.2, p = 0.01), were more likely to require an open operation (23.8 % vs. 2.8 %, p < 0.0001), and were more likely to have a drain placed intra-operatively (42.9 % vs 14.4 %, p = 0.004). While there were no differences in 30-day readmission rates, patients in the delayed group had a significantly longer hospital length of stay than patients in the immediate group (9.4 ± 7.4 vs. 3.1 ± 3.3, p = 0.008). Conclusions: Patients undergoing an immediate appendectomy for perforated appendicitis can discharge from the hospital sooner and demonstrate no increase in post-operative morbidity suggesting that surgeons can initially manage this disease process in an operative fashion.
RESUMEN
BACKGROUND: Determining the effect of reopening schools on pediatric SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection rates increased the need to share the experience of governments in many geographic regions for better future decision-making in similar health emergencies. METHODS: Through a prospective study based on a population-based cohort, students from 18,988 schools in the State of Mexico who began returning to school were followed. Daily sanitation filters were implemented in each school and district liaisons were informed on a daily basis through a negative network. Identified cases were confirmed by reverse transcriptase-polymerase chain reaction. Simple case frequencies, percentages, and incidences of COVID-19 were estimated. State incidences were compared with the national incidence. RESULTS: A total of 3,586 cases were confirmed; 2,048 (57.1%) were children. Twenty-four (0.6%) were hospitalized for moderate to severe COVID-19; nine (37.5%) died, and only one was a schoolchild. From week 36, an average infection rate of 0.36 was observed. The highest infection rate in schoolchildren was observed in epidemiologic week 40 (1.01); from this week on, a decrease in the number of cases was observed until week 50. CONCLUSIONS: The use of non-pharmaceutical interventions has more advantages than limitations, as long as the strategies are homogeneous and properly implemented to ensure adequate control of infections.
INTRODUCCIÓN: La determinación del efecto de reabrir las escuelas sobre las tasas de infección pediátrica por SARS-CoV-2 (síndrome respiratorio agudo grave coronavirus 2) incrementó la necesidad de trasmitir la experiencia de los gobiernos de muchas regiones geográficas para mejores decisiones futuras en emergencias sanitarias similares. MÉTODOS: Mediante un estudio prospectivo basado en una cohorte poblacional se dio seguimiento a los alumnos de 18,988 escuelas del Estado de México que iniciaron con el regreso a clases. Se implementaron filtros sanitarios diarios en cada escuela y cotidianamente se informaban a los enlaces jurisdiccionales a través de una red negativa. Los casos identificados eran confirmados a través de RT-PCR (reacción en cadena de la polimerasa con transcriptasa inversa). Se estimaron frecuencias simples de casos, porcentajes e incidencias de COVID-19. Las incidencias del estado se compararon con la incidencia nacional. RESULTADOS: Un total de 3,586 casos fueron confirmados; 2,048 (57.1%) correspondieron a niños. Veinticuatro (0.6%) fueron hospitalizados por COVID-19 moderado a grave; nueve (37.5%) fallecieron, y solamente una correspondió a un escolar. A partir de la semana 36 se observó una tasa promedio de infecciones de 0.36. En la semana epidemiológica 40 se observó la mayor tasa de infección en escolares (1.01); a partir de esta semana se observa un declive de los casos hasta la semana 50. CONCLUSIONES: La implementación de intervenciones no farmacéuticas tiene más ventajas que limitaciones, siempre y cuando las estrategias sean homogéneas y correctamente ejecutadas, lo que asegurará un adecuado control en los contagios.

RESUMEN
Skin and soft tissue defects of the lower extremity present a unique challenge for the reconstructive surgeon. Successful repair of the lower extremity relies not only on strong anatomical knowledge and surgical expertise, but also on careful consideration of the numerous preoperative factors and indications that may alter the patient's response to operative management. While many of these injuries result from burns, avulsive trauma, diabetes, or vascular insufficiencies, a significant portion can be associated with resection of neoplastic pathologies. This review outlines the uses, indications, and considerations for biologic wound agents in reconstructing skin and soft tissue defects of the lower extremity following Mohs micrographic surgery.
