Alveolar Proteinosis in COVID-19: Clinical Case.

Pulmonary alveolar proteinosis (PAP) is a rare, diffuse lung disease characterized by accumulation of lipoprotein in lung surfactant in the alveolar space and terminal bronchioles, leading to impaired gas exchange and arterial hypoxemia. We present the case of a 51-year-old woman who was admitted with a diagnosis of severe SARS-CoV-2 pneumonia. Her condition did not improve with corticosteroids.

Usefulness of Home Overnight Pulse Oximetry in Patients with Suspected Sleep-Disordered Breathing.

Methods: Prospective study conducted in a university hospital. Subjects with a clinical suspicion of SAHS were included. All of them underwent home polygraphy and oximetry on the same night.

Overnight Pulse Oximetry to Determine Prognostic Factors in Subjects With Amyotrophic Lateral Sclerosis.

Background: The objective of the current study was to determine whether overnight pulse oximetry in patients with amyotrophic lateral sclerosis is prognostic of the onset of awake respiratory failure and hospital admissions.

Methods: This was an observational study in a cohort of subjects with amyotrophic lateral sclerosis. The study included subjects with a baseline [Formula: see text] ≥ 94% on home overnight pulse oximetry testing.
