Posterior fossa tumors in children: An update and new concepts.

Background: Posterior fossa tumors account for approximately half of the central nervous system tumors in children. Major technological advances, mainly in the fields of molecular biology and neuroimaging, have modified their classification, leading to a more detailed description of these entities. Into the classic taxonomy, used for many years, new concepts have been incorporated at times eliminating or modifying former ones.

Long-tunneled versus short-tunneled external ventricular drain: a quasi-experimental study in a cohort of pediatric patients.

Objective: The primary aim of this study was to compare external ventricular drain (EVD)-related infection rates and mechanical complications between long-tunneled EVDs (LTEVDs) with an interposed valve and short-tunneled EVDs (STEVDs) in a cohort of pediatric patients. The second objective was to compare hospital resources used for LTEVDs versus STEVDs in the same cohort of patients and the same study period.

Methods: The study consisted of a quasi-experimental investigation comparing a prospective group of patients who received LTEVDs with a retrospective (historic) cohort of patients treated with STEVDs.

Surgical treatment of a patient with a giant choroidal fissure cyst: a case report.

Introduction: Choroidal fissure cysts (CFC) are usually an incidental finding on imaging and lead to morbidity only in rare cases. The aim of this study was to present the case of a patient with a giant CFC and its treatment.

Case Report: The patient was a male infant of 9 days of life that presented with symptoms of intracranial hypertension.

Abdominal complications in patients with a ventriculoperitoneal shunt: proposal for management recommendations from a single pediatric tertiary center.

Purpose: The aim of this study was to describe our experience in the management of patients with ventriculoperitoneal shunt-related complications (abdominal pseudocyst, bowel-related complications, and ascites) and to propose treatment recommendations.

Material And Methods: A retrospective descriptive study was conducted in patients with ventriculoperitoneal shunt-related abdominal complications seen between 2009 and 2019 at a tertiary-care pediatric center. Patients were classified according to their diagnosis into the following: group A (abdominal pseudocyst), group B (bowel-related complications), and group C (ascites).

Baclofen pump with pre-brainstem catheter tip placement: technical note and case series.

Purpose: This study aims to describe a new baclofen pump implantation technique with pre-brainstem catheter placement and to demonstrate the benefits that this procedure has in treating spasticity and dystonia.

Methods: We described a new technique to place a baclofen pump catheter anterior to the brainstem. To illustrate the technique, we presented five patients with both spasticity and dystonia in whom conventional treatment was not effective.

Melanotic neuroectodermal tumor of infancy arising from the skull: report of an unusual case, review of the literature, and a diagnostic approach.

Introduction: Melanotic neuroectodermal tumor of infancy is a rare neoplasm mainly seen in children under 1 year of life. The most common location of the tumor is the maxilla followed by the cranial vault. Surgery is the treatment of choice and outcome mainly depends on extent of resection.
