[Access to auto-adjustable positive airway pressure devices for the treatment of obstructive sleep apnea during the COVID-19 pandemic].

The use of positive airway pressure is the treatment of choice for obstructive sleep apnea. Since the beginning of SARS-CoV-2 virus pandemic the recommendations were to avoid the administration of this therapy in the sleep laboratory and to start treatment with autoadjustable continuous positive airway pressure devices. The objective was to evaluate access to these devices in the current epidemiological context.

Evaluation of the pulmonary function of patients with severe coronavirus 2019 disease three months after diagnosis.

There are few data regarding the repercussion in the pulmonary function of patients who had severe or critical COVID-19 pneumonia. The objective was to describe these patients' pulmonary function and establish an association with the severity of the disease (patients with severe or critical pneumonia), the presence of comorbidities, the tomographic involvement and the persistence of dyspnoea. Fifty-five patients were included, 40 (73%) male, media of age 54.

Acute peritoneal dialysis, complications and outcomes in 389 children with STEC-HUS: a multicenter experience.

Background: Management of acute kidney injury (AKI) in children with hemolytic uremic syndrome induced by a Shiga toxin-producing Escherichia coli infection (STEC-HUS) is supportive; however, 40 to 60% of cases need kidney replacement therapy (KRT). The aim of this study was to analyze procedure complications, especially peritonitis, and clinical outcomes in children with AKI secondary to STEC-HUS treated with acute PD.

Methods: This is a multicenter retrospective study conducted among thirty-seven Argentinian centers.

[Diffusing capacity for carbon monoxide, guidelines for interpretation].

The diffusing capacity for carbon monoxide (DLCO) is, after spirometry the standard and noninvasive pulmonary function test of greater clinical use. However, there are substantial errors in the interpretation of the physiological significance of the DLCO, its derived measures and, therefore the clinical significance of its alterations. In addition to the use of different nomenclatures, other sources of confusion have contributed to some negative view of the test.

Henoch-Schonlein purpura in pediatrics: Ten years of experience at a moderate risk office of a general hospital.

Introduction: Henoch-Schonlein purpura (HSP) is the most common small vessel leukocytoclastic vasculitis during childhood. It is characterized by palpable purpura and/or joint, abdominal or renal involvement.

Objective: To describe the epidemiological, clinical, laboratory, and evolutionary characteristics of patients with HSP.

[STOP-BANG, a useful and easy tool for the screening of obstructive sleep apnea].

The STO-BANG questionnaire, S standing for snore, T tired, O observed apneas, P pressure (arterial hypertension), B BMI (body mass index > 35 kg/ m2), A age (> 50 years old), N neck circumference (> 40 cm), G gender (male); is a simple tool that enables the detection of patients with obstructive sleep apnea syndrome (OSA). If the patient adds 3 or more points, it is considered to have a high probability of having this disease. Our goal was to evaluate the capacity of the STOP-BANG questionnaire and to compare it with the ability of a sleep trained pulmonologist in determining the probability of OSA.

Single-Dose Universal Hepatitis A Immunization in Argentina: Low Viral Circulation and High Persistence of Protective Antibodies Up to 4 Years.

Background: Single-dose hepatitis A virus (HAV) vaccination was implemented in all Argentinean children aged 12 months in 2005. Between 2005 and 2011, a dramatic decline was observed in HAV infection rates, fulminant hepatitis, and liver transplantation. This study assessed current viral circulation and estimated protective antibody persistence 4 years after vaccination.
