    Purpose Kaolin (aluminum silicate) has been used to generate hydrocephalus by direct cisterna magna injection in animal models. The aim of the present study is to compare which method of Kaolin injection into fetal cisterna magna is feasible, safer, and more effective to induce hydrocephalus in fetal lambs.

    Per oral endoscopic myotomy (POEM) in pediatric patients with esophageal achalasia: First Latin-American experience
    (2021) Saez, Josefina; Mejia, Ricardo; Pattillo, Juan Carlos; Vuletin, Fernando; Monrroy, Hugo; Jaime, Francisca; Sharp, Allan
    Background: Achalasia is the most common primary motor disorder of the esophagus, but its incidence in pediatric patients is low. Laparoscopic Heller myotomy (LHM) is the current surgical standard of care treatment. Per-oral endoscopic myotomy (POEM) has emerged as a safe and effective therapeutic alternative in adult patients. We herein report the outcomes of a cohort of pediatric patients with achalasia treated by POEM at a Chilean medical center. Methods: This is a retrospective analysis of prospectively collected data on children who underwent POEM for esophageal achalasia. Clinical follow-up was evaluated by recording the Eckardt score, a high-resolution esophageal manometry (HREM) three months after the procedure, and an annual upper gastrointestinal endoscopy.

    (2021) Saez, Josefina; Jesus Irarrazaval, Maria; Vidal, Cristina; Peralta, Felipe; Escobar, Raul G.; Avila, Daniela; Concha, Mario; Vuletin, Fernando; Carlos Pattillo, Juan
    Juvenile myasthenia gravis (JMG) is an autoimmune disease affecting the neuromuscular junction that appears before 19 years of age with varying degrees of weakness of different muscle groups. The main treatment is pharmacological, but thymectomy has also demonstrated to improve remission rates. Objective: To describe the clinical characteristics and postoperative course of pediatric patients with JMG who underwent video-assisted thoracoscopic (VATS) thymectomy. Clinical Serie: Six patients who underwent VATS thymectomy between March 2011 and June 2019. The age range at diagnosis was between 2 and 14 years and the average age at surgery was 7 years. All patients were under treatment with pyridostigmine bromide associated with immunosuppression with corticosteroids before surgery. The interval between diagnosis and thymectomy was 21.5 months on average. VATS was performed by left approach, and there was no perioperative morbidity or mortality. The average hospital stay was 2 days. Three patients remain with no symptoms and without corticotherapy. Two patients were on corticosteroids, but in smaller doses than previous to surgery. One patient presented a crisis requiring hospitalization and ventilatory support during follow-up. Conclusion: VATS thymectomy is part of the treatment for JMG. In this series, it appears as a safe approach and its results were favorable.
