Article Synopsis
  • Robot-assisted techniques in stereotactic brain biopsies have improved safety and precision, making them a viable option for tissue diagnosis of intracranial lesions.
  • A meta-analysis of 27 studies involving 2605 patients showed a high diagnostic yield of 98%, with a mean operative time of 52.45 minutes and a low risk of complications, including 6% for postoperative hemorrhage.
  • Overall, the study indicates that robot-assisted biopsies offer significant advantages in terms of effectiveness and reduced complications, solidifying their role in the future of neurosurgical diagnostics.

Background: Primary brainstem hemorrhage (PBSH) is a fatal condition related to hypertension. PBSH definitive treatment remains controversial, mainly when surgical options are discussed.

Objective: To aid decision-making in PBSH scenarios, we aimed to perform a meta-analysis and evaluate the literature on stereotactic aspiration (SA) for PBSH in comparison to conservative management (CM).

Chiari Malformation Type I (CMI) is a prevalent neurosurgical condition characterized by the descent of cerebellar tonsils below the foramen magnum. Surgery, aimed at reducing symptomatology and syrinx size, presents risks, making intraoperative neuromonitoring (IONM) a potentially vital tool. Despite its widespread use in cervical spine surgery, the utility of IONM in CMI surgery remains controversial, with concerns over increased operative time, cost, restricted anesthetic techniques and tongue lacerations.

Background And Objectives: Chronic subdural hematoma (CSDH) management involves various surgical techniques, with drainage systems playing a pivotal role. While passive drainage (PD) and active drainage (AD) are both used, their efficacy remains contentious. Some studies favor PD for lower recurrence rates, while others suggest AD superiority.

Background: Intracranial pressure (ICP) monitoring plays a key role in patients with traumatic brain injury (TBI), however, cerebral hypoxia can occur without intracranial hypertension. Aiming to improve neuroprotection in these patients, a possible alternative is the association of Brain Tissue Oxygen Pressure (PbtO2) monitoring, used to detect PbtO2 tension.

Method: We systematically searched PubMed, Embase and Cochrane Central for RCTs comparing combined PbtO2 + ICP monitoring with ICP monitoring alone in patients with severe or moderate TBI.

Background: Craniosynostosis, a developmental craniofacial anomaly, can impair brain development and cause abnormal skull shape due to premature closure of one or more cranial sutures. Traditional surgical treatments have evolved from open operations to minimally invasive endoscopic techniques. This systematic review and meta-analysis aim to evaluate the effectiveness and safety of the endoscopic approach in craniosynostosis correction.

Article Synopsis
  • Meckel-Gruber Syndrome (MKS) is a severe genetic disorder characterized by occipital encephalocele, polycystic renal dysplasia, and postaxial polydactyly, leading to high mortality rates, often before or shortly after birth.
  • A systematic review of the literature analyzed 10 cases of newborns with MKS who underwent surgical excision of encephaloceles, revealing complications and outcomes related to the procedure.
  • Findings included an average gestational age of 36 weeks, common neurological issues like hydrocephalus, and a significant number of patients requiring post-surgical interventions such as mechanical ventilation, with pneumonia being a frequent cause of death.

Objective: To assess the efficacy and surgical outcomes of the simultaneous single-trajectory endoscopic biopsy and third ventriculostomy (ETV) in pineal region tumors.

Methods: A systematic review and meta-analysis adhering to Cochrane Standards and PRISMA framework were conducted. PubMed, Embase, and Web Of Science databases were searched until December 2023.

Indications Corridor And Limits Of Exposure: This approach is suitable for petroclival lesions medial to V cranial nerve that extend in both middle and posterior fossa. It provides multiple surgical corridors with minimal brain retraction.

Anatomic Essentials Need For Preoperative Planning And Assessment: Several critical neurovascular structures of the petrous bone are at risk during the approach.

Purpose: Our purpose was to verify the existence of birthplace and relative age effect (RAE), as well as the association between birthplace effect and RAE among Brazilian athletes competing in the Olympic Games.

Methods: Data included information about Brazilian Summer Olympic athletes from 1920 to 2021. To investigate RAE, athletes' birthdate was distributed into birth quartiles (Q1: Jan-Mar; Q2: Apr-Jun; Q3: Jul-Sep; Q4: Oct-Dec), while birthplace effect was assessed considering the state and the region (Southeast; Northeast; South; North; and Midwest) of birth.

Background: Care for children who are hospitalized can be optimized if the pharmacist, in conjunction with the multidisciplinary team, promotes the rational use of medicines. In this sense, the evaluation of the quality of these clinical services through indicators is important in the planning, decision making of pharmacists and managers of these services.

Objective: To characterize which health indicators were influenced by the pharmaceutical clinical services for the care of children in hospitals.

Chordomas of craniovertebral junction represent a challenging pathology for neurosurgeons, due to their deep location, proximity with critical neurovascular structures and local aggressiveness. Several surgical options are available for these tumors: both endoscopic extended approaches and open approaches. We present the case of a 24 years old female with a craniovertebral junction chordoma with anterior and right lateral extension.

Large anterior clinoidal meningiomas are tumors that arise on the anterior clinoid often compressing and encasing the nearby neurovascular structures such as the carotid artery and the optic nerve. These remain as very challenging cases for neurosurgeons because of the issues concerning preservation of critical structures and gross total excision. In this video submission, we will show a case of a large anterior clinoidal meningioma through a tailored frontotemporoorbitozygomotic craniotomy with emphasis on anterior clinoidectomy and the different corridors that can be obtained by this particular approach.

Background: Cancer is a major public health problem that imposes limitations on patients being treated. One of the strategies to improve health outcomes in cancer patients and promote the safety of their treatment is the provision of pharmaceutical clinical services (PCS). However, there is no evidence of health outcomes that are influenced by such services.

Introduction: Each patient admitted to the hospital is subject to one medication error per day, since the occurrence of this one with the potential to cause harm is three times more common in pediatric hospitalized patients than in adults. These harms can result from inaccurate or incomplete drug use histories when patients undergo a clinical evaluation, which jeopardizes patient safety and compromises hospitalization costs. Thus, medication reconciliation (MC) emerges as a possible solution to avoid the occurrence of these in pediatric patients and directly contributes to reducing costs in the hospital environment and increasing quality of life).

Eosinophilic esophagitis (EoE) is a chronic inflammatory condition of the esophagus characterized by increased number of eosinophils. Currently, EoE diagnosis is based on endoscopic procedures for histopathological examination, eosinophils' counting and, often, in clinical practice, the challenge is the differentiation between EoE and gastroesophageal reflux disease (GERD). Our aim was to develop novel peptide ligand to Eosinophil cationic protein (ECP) present in EoE biopsies of patients with potential to be used for detection.

While mass immunization against coronavirus disease 2019 (COVID-19) rolls out around the globe, safety concerns and adverse events that need prompt evaluation are also emerging. Neurological complications such as transverse myelitis raise concerns as cases were observed in clinical trials. Cerebrospinal fluid analysis is routine in these cases and the characteristics of the abnormalities found are of great help not only in establishing the diagnosis but also in understanding this rare condition.
