Cervical Intramedullary Spinal Cord Abscess Secondary to Discitis and Osteomyelitis in an Immunocompromised Patient.

Intramedullary spinal cord abscess is a rare neurological condition, not commonly suspected and often misdiagnosed. Even after a prompt diagnosis and treatment, most patients persist with permanent neurological deficits. In adults, factors such as immunocompromised, intravenous drug use, endocarditis, and sepsis could be associated with its development.

Neurosurgical Injuries Associated With the Use of Personal Watercrafts.

Introduction:  A personal watercraft is widely used for recreation on coastlines, rivers, and lakes. This study aimed to identify the spectrum of neurosurgical injuries related to personal watercraft accidents in Puerto Rico.

Methods: A retrospective study was performed utilizing the University of Puerto Rico neurosurgery database to identify patients who had been consulted to the neurosurgery service from 2005 to 2023 due to a personal watercraft-related neurosurgical injury.

Efficacy of Hydromer-Coated and Antibiotic- Impregnated Shunt Systems in Reducing Early Shunt Infections in the Pediatric Population.

Objective: Shunt infection is the most common complication following a Cerebrospinal fluid (CSF) diversion procedure with devastating consequences. This study analyzes the efficacy of different shunt systems in reducing early shunt infections in the pediatric population.

Methods: Retrospective case study analysis of 177 pediatric patients with hydrocephalus de novo shunted using hydromer-coated (HC) shunt systems, antibiotic-impregnated (AI) shunt systems and standard non impregnated shunt systems was performed and compared for the incidence of shunt infection in the early postoperative period.

Cavernous Malformation of a Thoracic Spinal Nerve Root: Case Report and Review of Literature.

Intradural extramedullary spinal cavernous malformations (CMs) remain the least common variant of these lesions and can originate from the inner surface of the dura mater, the pial surface of the spinal cord, and the blood vessels in the spinal nerves. Root-based-only extramedullary CMs are very rare in the thoracic region with only four cases reported. We present a case of 56-year-old male with 1-year progression of lower extremities weakness.

Chordoid Glioma with Psychosis: Case Report.

Objective: A rare, low-grade tumor found in the hypothalamus and anterior third ventricle, a chordoid glioma presents a challenge to neurosurgeons: Its successful resection is complicated by its inconvenient location.

Case Description: A 42-year-old male patient presented with a 1-year history of major depressive disorder, with psychotic features associated with generalized tonic-clonic seizures. Brain magnetic resonance imaging (MRI) with contrast revealed a suprasellar mass extending into the third ventricle To resect the lesion, an interhemispheric transcallosal transventricular subfornical approach was used.

Acute adrenal insufficiency in cervical spinal cord injury.

Background: Adequate adrenal response is fundamental for the maintenance of physiological homeostasis in the setting of trauma and severe illness. Patients with neurogenic shock are at risk of severe consequences if adrenal insufficiency (AI) is not rapidly identified and treated.

Objective: To analyze the incidence of AI in patients with acute cervical spinal cord injury and its effect on in-hospital complications.

Vagus nerve stimulation for intractable seizures in children: the University of Puerto Rico experience.

Objective: Vagus nerve stimulation (VNS) is considered an alternative treatment for patients with medically refractory epilepsy who are not candidates for resective surgery. It consists of intermittent electrical stimulation of the left vagus nerve in the neck. Such stimulation has been demonstrated to be efficacious, safe, and well tolerated, offering these patients another option for seizure control.
