Importance of early endoscopic and clinical evaluation of children with caustics ingestion.

Background: Accidental ingestion of caustics in pediatrics continues to be a frequent problem that can lead to severe injuries and permanent sequelae that require esophageal rehabilitation programs. This study aimed to describe the medical care experience of children who ingested caustic substances in a tertiary hospital in Mexico City.

Methods: We conducted a descriptive and analytical study.

Efficacy of 1-day vs. 2-day intestinal preparation using peg 3350 + Bisacodyl: A randomized clinical trial.

Objective: The objective was to compare the efficacy of 1-day intestinal preparation for colonoscopy using PEG 3350 (polyethylene glycol) (4 g/kg/day) + bisacodyl vs. 2-day intestinal preparation using PEG 3350 (2 g/kg/day) + bisacodyl in pediatric patients.

Materials And Methods: A blind, randomized clinical trial was carried out with endoscopists who assessed colon cleansing.

Pediatric airway tumors: A report from the International Network of Pediatric Airway Teams (INPAT).

Objective: Primary tracheobronchial tumors (PTTs) are rare heterogeneous lesions arising from any part of the tracheobronchial tree. Nonspecific symptoms may lead to delayed diagnosis that requires more aggressive surgical treatment. An analysis of cases collected by the International Network of Pediatric Airway Team was undertaken to ensure proper insight into the behavior and management of PTTs.

Epiglottopexy by external puncture for epiglottic prolapse in severe laryngomalacia. A novel technique.

Introduction: Laryngomalacia (LM) is the first cause of stridor in infants. 10 to 20% of patients with LM may require surgery due to the development of severe symptoms. Supraglottoplasty is the most commonly performed surgery for severe LM.

[Tiempo de respuesta terapéutica al propranolol sistémico en el manejo de hemangiomas subglóticos pediátricos: serie de casos y revisión de la literatura].

Background: Airway hemangiomas are congenital neoplasms of low incidence. Its clinical presentation consists of obstruction of the upper airway with progressive dyspnea and stridor and the life of the patient at risk. Infantile hemangiomas have an incidence at birth of 2%, increasing to 9% at 12 months of life.

Characteristics and outcomes of foreign body ingestion in children.

Introduction: Foreign body (FB) ingestion is a common home accident during childhood; a timely management by the specialists may help prevent complications in the short and long term.

Objective: To describe the characteristics and complications of FB ingestion located in the gastrointestinal tract in the pediatric population.

Material And Methods: Two phases, retrospective, and prospective study.

[Pulmonary sequestration associated with congenital pulmonary airway malformation].

Introduction: Congenital pulmonary malformations are a rare cause of neonatal morbidity. Some of them have a common origin, which allows the identification of combined lesions. Its diagnosis can be made prenatally by ultrasound, with the limitation that this study is performed in specialized centers and depends on the expertise of the operator.

[Tolerance, safety and efficacy of the one-day preparation of PEG3350 + bisacodyl compared to 2 days of PEG3350 + bisacodyl in pediatric patients].

Background: Multiple intestinal preparations have been used in children undergoing colonoscopy, with variable limitation due to acceptance, tolerance, and proper cleaning. The objective of this study was to compare the tolerability, safety and efficacy of the colonoscopy preparation with 1 day with PEG 3350 (poliethylenglycol) (4g/kg/day) + bisacodyl compared to 2 days of preparation with PEG 3350 (2g/kg/day) + bisacodyl in pediatric patients.

Methods: A clinical, randomized, and blind trial was performed.

Extended cricotracheal resection with posterior costochondral grafting for complex pediatric subglottic stenosis.

Background And Objective: Severe laryngotracheal stenosis in childhood poses a complex surgical challenge for specialists in airway surgery. Patients with severe subglottic stenosis with vocal cord involvement are particularly difficult to manage successfully. The goal of this work was to review our experience with extended CTR in a cohort of young children with severe SGS and determine which clinical parameters would be associated with surgical success.

[Pulmonary aplasia: report of two cases].

Background: Pulmonary aplasia is a rare disorder of lung development characterized by the presence of a rudimentary main bronchus in the absence of lung and pulmonary artery. It is generally associated with other congenital defects and must be suspected in the presence of a total radiopaque hemithorax.

Case Reports: We describe two cases of pulmonary aplasia diagnosed in the Hospital Infantil de México "Federico Gómez" in the last 5 years.

[Foreign bodies aspiration in pediatrics. 15-year experience. Analysis of 337 cases].

Foreign body aspiration is a pediatric urgency that occurs primarily between 1 and 3 years old. The aim of this paper is to present the symptomatology, clinical and radiological findings, and the therapeutic used in our hospital with patients with foreign body aspiration diagnosis from 1995 until 2011. Patient's age was between 0 and 16 years old.

Transluminal endoscopic electrosurgical incision of fenestrated duodenal membranes.

Duodenal fenestrated membranes are traditionally treated by side-to-side diamond-shaped duodenoduodenostomy, or duodenotomy and resection. We describe an alternative endoscopic approach for its resolution. A flexible panendoscopy reaching the duodenal membrane was performed.

[Anterior approach for the surgical treatment of a laryngotracheoesophageal cleft].

Laryngotracheoesophageal clefts (LTEC) are rare and potentially lethal malformations. Their therapeutic approach is still controversial. We report on a one month old infant with a type III LTEC who presented with aspiration and was fed through an orogastric tube for three weeks.

A new endoscopic procedure for membranectomy of fenestrated duodenal membranes.

Aim Of The Study: We describe a new endoscopic procedure for membranectomy of fenestrated duodenal membranes.

Methods: With the patients under general anesthesia and tracheally intubated, a flexible video-panendoscope was introduced into the second portion of the duodenum. The fenestrated membrane was visualized and a triple-lumen stone extraction balloon of 15 mm was inserted through the fenestration.

Preoperative catheterization of H-type tracheoesophageal fistula to facilitate its localization and surgical correction.

Purpose: The aim of this study was to demonstrate that preoperative catheterization of H-type tracheoesophageal fistula facilitates its identification and surgical correction.

Methods: This is a case series of seven patients with H-type tracheoesophageal fistula. Diagnosis was established in three patients and suspected in two more by means of an esophagogram.

Primary cricotracheal resection with thyrotracheal anastomosis for the treatment of severe subglottic stenosis in children and adolescents.

Severe subglottic stenosis in children is best managed by laryngotracheal reconstruction or cricotracheal resection (CTR). We describe clinical outcomes with CTR and end-to-end anastomosis in pediatric patients with severe subglottic stenosis in a tertiary-care pediatric teaching hospital in Mexico City. We prospectively followed up all consecutive patients younger than 18 years of age with a Myer-Cotton grade 3 or 4 subglottic stenosis who underwent CTR between May 1, 2000, and March 31, 2003.
