Early postoperative complications of intracranial tumors in children.

BACKGROUND: The aim of this study was to describe the complications experienced by patients after central nervous system tumor resection during pediatric intensive care Unit (PICU) admission. Our attempt was to assess the association between epidemiological, clinical data and tumor characteristics prior to surgery and presence of postoperative complications. METHODS: We design an observational, descriptive and retrospective study by review of medical records. Patients aged 0-18 years, admitted to the PICU of our hospital, after surgery for tumor resection in the central nervous system. RESULTS: We collected a total of 145 postoperative. At PICU, 48.3% of the patients (70/145) had some type of postoperative complication. It they were, in order of frequency: a new neurological deficit at discharge (29%, 42/145), pneumocephalus (21%, 30/145), electrolyte disturbances (17.9%, 26), infection (16.6%, 24), anemia (8.3%, 12), seizures (7.6%, 11), endocrine disorders (7.6%, 11), intracranial hypertension (5.5%, 8) and stroke (7, 4.8%). One patient died. There was no difference in overall complication and the tumor site. However, supratentorial tumors had less need for MV (73% vs. 92%, P=0.002, OR 2.7 [1.2-6.1]), shorter duration for MV (11 hours vs. 48 hours, P=0.02), lower frequency of neurological deficit (22% vs. 37%, P=0.004, OR 1.4 [1-2.1]) and cerebrospinal fluid fistula (1% vs. 13%, P=0.004, OR 2.1 [1.6- 2.8]). They were more frequent seizures (13% vs. 2%, P=0.024, OR 1.8 [1.4-2.3]), central diabetes insipidus (17% vs. 0%, P<0.001, OR 4.3 [1.6-11.7]) and endocrine disruption (14% vs. 0%, P=0.001, OR 2 [1.7-2.4]). CONCLUSIONS: The intracranial tumors surgery requires monitoring in intensive care because the risk of postoperative complications is high. The tumor location is related to the occurrence of some of these complications.

Respiratory Failure in Children With Hemato-oncological Diseases Admitted to the PICU: A Single-center Experience.

Respiratory failure (RF) is a main cause of pediatric intensive care unit (PICU) admission in children with hemato-oncological diseases. We present a retrospective chart review of children admitted to our PICU because of RF (January 2006 to December 2010). The aims of this study are the following: (1) to describe the demographical and clinical characteristics and respiratory management of these children; and (2) to identify the factors associated with mechanical ventilation (MV) and mortality. A total of 69 patients, encompassing 88 episodes, were included (55/88 cases were hypoxemic RF). The first respiratory support at PICU admission was, in decreasing order of frequency, high-flow oxygen nasal cannula (HFNC; 50/88), noninvasive ventilation (NIV; 13/88), and oxygen nasal cannula (16/88). MV was necessary in 47/88 episodes, 38/47 after another respiratory support. In 18/28 children with initial NIV, MV was required later. MV was associated with O-PRISM score, NIV requirement, suspected respiratory infection, and days of PICU treatment. Patients without MV showed an increased survival rate (P=0.001). In summary, the hypoxemic RF was the main cause of PICU admission, and HFNC or NIV was almost always the first respiratory support. The use of MV was associated with a higher mortality rate. The utility of precocious HFNC or NIV should be investigated in larger clinical studies.

Síncope como forma de presentación de masa mediastínica / Syncope in the debut of a mediastinal mass

El síncope supone el 3 por ciento de las consultas en los servicios deurgencias. En pediatría es frecuente, especialmente en niñas adolescentes de entre 15 y 19 años, quienes hasta un 25 por ciento hansufrido un episodio sincopal. La mayoría de las causas son benignas, pero el objetivo en la evaluación inicial de un paciente con síncope es descartar aquellas que supongan compromiso vital; una enfermedad cardíaca puede debutar en forma de síncope en un 10-28 por ciento de los casos. La historia clínica detallada y una exploración física exhaustiva son suficientes en la mayoría de las situaciones para descartar patología orgánica. Presentamos el caso de un paciente con linfoma B difuso de células grandes localizado en el mediastino cuyo diagnóstico se realizó tras episodios sincopales de repetición.

[Syncope in the debut of a mediastinal mass]. / Síncope como forma de presentación de masa mediastínica.

Pediatric syncope accounts for 3% of the consultations in emergency department. It is frequent in pediatrics, particularly in teenager girls between 15 and 19 years old, and up to a 25% of them have suffered from a syncopal episode. Most causes are benign, but the aim in its initial evaluation is ruling out those which mean any danger. Heart disease can lead to syncope in a 10-28% of cases. A detailed medical history and an exhaustive exploration are enough to rule out organic pathology in most situations. We present the case of a diffuse large B cell lymphoma located in the mediastinum diagnosed after repetitive syncopal episodes.
