Metabolic bone disease in premature infants receiving parenteral nutrition: Incidence, clinical, laboratory and nutritional profile.

Background: Metabolic bone disease (MBD) of newborns (NB) is characterized by tissue reduction and inadequate postnatal bone mineralization with clinical, laboratory, and/or radiologic repercussions between the third and twelfth weeks of postnatal life, which, in its most severe forms, can lead to a growth deficit and fractures. The aim of our study is to evaluate the incidence of MBD in premature patients receiving parenteral nutrition for >15 days in the neonatal intensive care unit (NICU) and assess their clinical and laboratory characteristics.

Methods: Single-center retrospective cohort study.

Residual Cholesteatoma After Endoscopic-Assisted Canal Wall-Up Tympanomastoidectomy: A Randomized Controlled Trial.

Objective: This study aimed to determine the effectiveness of using endoscopes in reducing recidivism secondary to residual cholesteatoma after canal wall-up tympanomastoidectomy.

Study Design: Randomized clinical trial.

Setting: Tertiary referral center.
