Pulmonary alveolar proteinosis (PAP) is a rare, diffuse pulmonary disease due to abnormal surfactant homeostasis. We present the case of a 69-year-old woman who was admitted to the hospital for progressive dyspnea with marked limitation in activity, and non-productive cough, of three months of evolution. ⋯ Histological diagnosis was made and whole-lung lavage was performed with clinical improvement. We highlight the need to keep in mind differential diagnoses of respiratory failure and pulmonary infiltrates during COVID-19 pandemic, even rare entities such as PAP.

Since their approval in 2011, immune checkpoint inhibitors (ICPis) are increasingly used to treat several advanced cancers. ICPis target certain cellular molecules that regulate immune response resulting in antitumor activity. The use of these new agents needs careful monitoring since they brought a whole new spectrum of adverse events. ⋯ Immune-related endocrine toxicities include thyroid dysfunction, hypophysitis and, less frequently, type 1 diabetes, primary adrenal insufficiency and hypoparathyroidism. Diagnosis of endocrine adverse events related to ICPis therapy can be challenging due to nonspecific manifestations in an oncological scenario and difficulties in the biochemical evaluation. Despite the fact that these endocrine adverse events could lead to life-threatening consequences, the availability of effective replacement treatment enables continuing therapy and together with an interdisciplinary approach will impact positively on survival.

Multicenter Study
AISYF: first national, prospective, multicenter study of young patients with stroke in Argentina.
Up to 15% of all strokes affect young patients and the incidence of ischemic stroke in this population is rising. Nevertheless, there is limited information of cerebrovascular events in this population both in our country and in Latin America. The aim of our study was to evaluate the clinical characteristics and risk factors of young adults with stroke in Argentina. ⋯ Stroke subtypes were: large artery disease 12.3%, cardioembolism 7.5%, small artery occlusion 11.5%, other defined etiology 27.1%, and undetermined etiology 41.6%. Our study demonstrates that vascular risk factors are very frequent in young adults with stroke. Our findings underline that urgent strategies are required for primary and secondary stroke prevention in this group of patients.
