Adequate timing of diagnostic tests for gastroesophageal reflux in children with esophageal atresia.

Objective: Recent guidelines made recommendations for the management of gastroesophageal reflux in patients with esophageal atresia (EA). However, the timing for some diagnostic tests remained somehow unclear. This investigation studied the tests for gastroesophageal reflux in children aged one year old and children aged two or three.

Fibrin glue treatment associated or not with diathermy for recurrent tracheoesophageal fistula: our results after more than 20 years' experience.

Introduction: Recurrent tracheoesophageal fistula (RTEF) is a frequent complication (5-10%) in patients with esophageal atresia (EA). Open RTEF surgery has a high morbidity and mortality, so the endoscopic approach represents a promising alternative. We present the long-term results of fibrin glue (FG) bronchoscopic application in patients with RTEF secondary to EA, which was first used by our team in 1994.

Eighteen years of experience with pediatric nutcracker syndrome: the importance of the conservative approach.

Introduction: Nutcracker syndrome (NS) defines an entity generated by the compression of the left renal vein resulting in venous hypertension, which transmitted in a retrograde direction may cause hematuria, proteinuria, and varicocele. The literature concerning exclusively pediatric patients is very rare.

Objective: To report the authors' experience with pediatric NS in the last 18 years.

[Applicability of a clinical score in patients with suspected foreign body aspiration].

Objective: To validate the clinical score of Valdivieso et al. in the management of patients with suspected foreign body aspiration in a tertiary hospital. This score raises different scenarios according to the result: bronchoscopy, CT, observation or discharge.

Halloysite nanotubes as tools to improve the actual challenge of fixed doses combinations in tuberculosis treatment.

Halloysite nanotubes (HLNTs) were used as nanocarriers of the tuberculostatic agent isoniazid (INH), a BCS (Biopharmaceutics Classification System) class III drug. Self-assembling nanohybrids (INH-loaded HLNTs) with an average outer diameter of 90 nm and polydispersity index of 0.7 approximately, were obtained by spontaneous adsorption of INH molecules to HLNTs powder in aqueous medium.
