Tubular single-port endoscope-assisted surgery for fetal myelomeningocele repair.

Objective: The authors aimed to describe a low-cost and easily reproducible alteration of the Bruner and Tulipan procedure to preserve uterine muscular fibers. They conducted a retrospective cohort study of 10 pregnant women whose fetuses developed lumbosacral myelomeningocele (MM). The MM was repaired through a fetal neurosurgical procedure using a tubular single-port endoscope-assisted technique.

Endoscopic Techniques in Sagittal Synostosis Correction: A Systematic Review and Meta-Analysis.

Background And Objectives: Scaphocephaly is a craniofacial deformity caused by the premature fusion of the sagittal suture, which can affect skull growth and shape. For decades, surgical treatment or craniosynostosis has involved open procedures, ranging from the removal of a single suture to complex cranial remodeling techniques with large skin incisions. Since the 1990s, endoscopic approaches have emerged as potentially less invasive options.

Unilateral Hemilaminectomy as Primary Treatment for Spinal Cord Tumors: Retrospective Cohort of 38 Cases with a Minimum Follow-Up of 24 Months.

Objective: To evaluate the efficacy of hemilaminectomy as an approach to intradural tumors and to assess the risk of postoperative spinal instability.

Methods: This is a retrospective cohort study of 38 patients who underwent surgical resection of intradural tumors between November 2014 and March 2019. Clinical and radiologic data were documented in medical records, from which we obtained clinical data including age, gender, tumor etiology, lesion level, type of resection, and postoperative instability during follow-up.

Analysis of long-term family dynamics in mothers who have undergone fetal myelomeningocele surgery using telemedicine: a pilot study.

Objective: The aim of this study was to understand the dynamics of families with children with myelomeningocele undergoing intrauterine fetal surgery.

Methods: A retrospective cohort pilot study was carried out with 11 mothers of children who had undergone intrauterine myelomeningocele repair. Participants in this study responded to an electronic questionnaire (via Google Forms), developed by the study authors, that consisted of 22 multiple-choice questions, of which 17 were closed-ended and 5 had a standardized format.

Intracranial non-germinomatous germ cell tumors in children and adolescents: how can the experience from an uppermiddle-income country contribute to the worldwide effort to improve outcomes?

Background: Non-germinomatous germ cell tumors (NGGCT) accounts for one third of intracranial GCT. While the germinoma group have an excellent overall survival, the standard of practice for children with NGGCT is still under evaluation.

Aims: Describe the results of the of the Brazilian consortium protocol.

"The blue catheter" - case report.

The ventriculoperitoneal shunt placement procedure is common throughout the world, with a prevalence of approximately 30,000 procedures per year in the United States (5). However, the rate of complications is still important and must be remembered, with a percentage of 11 to 25% after the first year of implantation. Abdominal complications are described in 5-47% of the cases (6), and the abdominal pseudocyst is one of them.

Treatment of depressed skull fractures with vacuum devices in the neonatal period: A case series.

Purpose: The management of depressed skull fractures in infants can be either conservative or surgical. This study aimed to examine the outcomes of management with a negative-pressure vacuum device on depressed skull fractures in newborns.

Methods: Twenty-eight patients (aged 1-6 days) with simple depressed skull fractures underwent skull elevation using negative-pressure vacuum devices.

Outcomes and surgical approaches for pineal region tumors in children: 30 years' experience.

Objective: Pineal region tumors account for 2.7%-11% of all CNS tumors in children. In this series, the authors present their surgical results and long-term outcomes from a pediatric pineal region tumor cohort.

Outcome of Children and Adolescents With Primary Intracranial Germinoma Treated With Chemotherapy and Reduced Dose-Field Irradiation: A Prospective Brazilian Experience.

Purpose: This prospective Brazilian single-arm trial was conducted to determine response to chemotherapy and survival after response-based radiotherapy in children with intracranial germinomas, in the setting of a multi-institutional study in a middle-income country (MIC) with significant disparity of subspecialty care.

Patients And Methods: Since 2013, 58 patients with histologic and/or serum and CSF tumor marker evaluations of primary intracranial germ cell tumors were diagnosed; 43 were germinoma with HCGβ levels ≤200 mIU/mL and five between 100 and 200 mIU/mL. The treatment plan consisted of four cycles of carboplatin and etoposide followed by 18 Gy whole-ventricular field irradiation (WVFI) and primary site(s) boost up to 30 Gy; 24 Gy craniospinal was prescribed for disseminated disease.

Diencephalic syndrome-like presentation of brainstem tumor: a series case-based review.

Purpose: Russel described a rare clinical entity known as diencephalic syndrome (DS) in 1951, which was traditionally caused by a neoplasm in the hypothalamic-optic chiasmatic region. DS is characterized by severe emaciation despite adequate or slightly reduced caloric intake, locomotor hyperactivity, euphoria and other minor features. Current evidence suggests that a rare population of children with a similar phenotype may have their tumor located in the posterior fossa instead, defining the DS-like presentation, a rare entity with few cases reported in the literature.

Decompressive craniectomy index: Does the size of decompressive craniectomy matter in malignant middle cerebral artery infarction?

Background: Malignant middle cerebral artery (MCA) infarction is associated with high mortality, mainly due to intracranial hypertension. This malignant course develops when two-thirds or more of MCA territory is infarcted. Randomized clinical trials demonstrated that in patients with malignant MCA infarction, decompressive craniectomy (DC) is associated with better prognosis.
