Características y resultados de pacientes COVID-19 tratados con ventilación mecánica invasiva en Hospital San Juan de Dios. Marzo-junio 2020

Background: The overall mortality of patients with COVID-19 admitted to intensive care units is approximately 40%. Aim: To describe the characteristics of a cohort of patients with COVID-19 who required invasive mechanical ventilation due to severe hypoxemic acute respiratory failure at a general hospital in Santiago, Chile. Material and Methods: Review of medical records and follow up for 28 days of patients with COVID-19 confirmed by polymerase chain reaction who required invasive mechanical ventilation and who were admitted to the intensive care unit from March 24 to June 7, 2020. Results: Data from 152 patients aged 58 (interquartile range (IQR) 47-65 years (66% men) was analyzed. As of July 5, 36 (24%) had died, 75 (49%) were discharged, 10 (7%) were still on invasive mechanical ventilation, 11 (7%) remained with tracheostomy but without invasive mechanical ventilation, and 20 (13%) were hospitalized in a basic unit. The median time on invasive mechanical ventilation among extubated patients was 14 days (IQR 10-21) and 121 (80%) were in the prone position. Patients who died were older, had a higher frequency of diabetes mellitus and a higher driving pressure at 7 days than those discharged alive from the intensive care unit. Conclusions: In this study mortality was lower than that reported in the first international studies, probably due to the selection of younger patients and greater knowledge of the disease.

¿Qué hay de nuevo en el síndrome de ovario poliquístico? / What’s new in polycystic ovary syndrome

Polycystic ovary syndrome is recognized as a risk factor for the development of type 2 diabetes and metabolic syndrome. The prevalence of the condition is 6 to 10 percent in different populations. Its etiology is not well known and there are genetic and epigenetic phenomena involved. Due to its association with insulin resistance, it has been incorporated as another component of Reaven plurimetabolic syndrome. Therefore polycystic ovary syndrome evolved from an ovarian disease to a multisystem disorder and it must be considered a public health problem.

Diagnostic work up disclosed a primary hyperparathyroidism secondary to a right parathyroid adenoma. The patient was subjected to a parathyroidectomy. After one year of follow up, symptoms have decreased considerably, laboratory parameters are normal and bone lesions are disappearing.
