[Correlation in radiological bone age determination using the Greulich and Pyle method versus automated evaluation using BoneXpert software].

Objective: To determine the degree of correlation in the radiological bone age assessment using the Greulich and Pyle method versus automated assessment through BoneXpert® software between 2013 and 2016.

Material And Method: Correlation study of diagnostic techniques of 1500 carpal X-rays to assess bone age in patients under 16 years of age from Clínica Alemana de Santiago. X-rays with bone age assessment using the Atlas of Greulich and Pyle (GP) by 1 out of 7 pediatric radiologists, were analyzed using the BoneXpert (BE) software for automated bone age assessment.

[Gastric band erosion as complication of bariatric surgery. Case report and review of the literature].

Gastric banding has become a common procedure amongst bariatric surgery techniques. Because of the possibility of using a laparoscopic route to achieve a good technical result and low complication rates, this method has become the most frequently used options in the treatment of morbid obesity in Chile. We report an uncommon complication that, if left undiagnosed, could lead to considerable morbidity and even mortality: gastric band erosion and intragastric migration.
