Objective: To evaluate the clinical and demographic characteristics of patients with juvenile idiopathic arthritis (JIA) in Chile and compare treatments and outcomes before and after the introduction in 2010 of the Explicit Health Guarantees (GES) for JIA, a national universal access program for diagnosis and treatment of this condition.
Methods: The clinical records of 280 patients with JIA followed at a private tertiary academic health network between 2007 and 2018 were reviewed.
Results: Seventy percent of patients with JIA were female, mean age at diagnosis was 8.
Chronic nonbacterial osteomyelitis (CNO) is a primary autoinflammatory bone disease that presents more frequently in children and is characterized by inflammatory bone lesions in the absence of an infectious etiology. There is little information of this disease in Latin America. The objective of the study was to evaluate demographic, clinical, laboratory, imaging, histopathology characteristics, and treatment responses of pediatric CNO patients.

- Food protein-induced allergic proctocolitis (FPIAP) is the most common non-IgE mediated food allergy in infants, but diagnosing it currently relies on food challenges rather than non-invasive tests like the fecal occult blood test (FOBT).
- A study was conducted comparing infants with suspected FPIAP to healthy infants using FOBT; results showed a high sensitivity (84%) for detecting FPIAP, but also a significant false positive rate (34% in controls).
- Due to the high rate of abnormal FOBT results in healthy infants, the study concludes that routine use of FOBT for diagnosing FPIAP is not recommended despite its adequate sensitivity.
