Idiopathic Interstitial Pneumonia Associated With Autoantibodies: A Large Case Series Followed Over 1 Year.

Background: Some patients with autoimmune characteristics and idiopathic interstitial pneumonia, particularly usual interstitial pneumonia (UIP), do not fit neatly into the category of connective tissue disease-associated interstitial lung disease (CTD-ILD), idiopathic pulmonary fibrosis (IPF), or recently proposed yet to be validated criteria for interstitial pneumonia with autoimmune features (IPAF). Outcomes of these patients are unknown.

Methods: This was a retrospective single-center study.

Differences in prevalence of geohelminth infections between indigenous and settler populations in a remote Amazonian region of Peru.

Objective: To compare prevalences of intestinal helminths and waterborne protozoa in indigenous and settler populations in a remote area of Peru. These populations live in adjacent but segregated small urban villages.

Methods: Stool samples were collected from representative members of these two populations and analysed for geohelminths and protozoa.
