Obstructive hydrocephalus is a rare complication of pituitary prolactinomas, especially in women, where symptoms amenorrhoea rarely go unnoticed. In this study, case female her 20s with 2-month history frontotemporal headache, acutely worsening over 3 days, presented. Cranial imaging showed sellar-suprasellar mass (2.6 × 3.5 3.6 cm) associated obstructive and tonsillar herniation. Hyperprolactinaemia was confirmed, cabergoline initiated. Clinically, the patient’s headache resolved within 24...

Despite the high number of children treated in emergency departments, patient safety risks this setting are not well quantified. Our objective was to estimate risk and type adverse events, as their preventability severity, for a paediatric department. prospective, multicentre cohort study enrolled presenting care during one 168 8-hour shifts across nine departments. primary outcome an event within 21 days enrolment which related provided at visit. We identified 'flagged outcomes' (such...

Background: Decompressive hemicraniectomy (DH) has been performed for some cases of acute ischemic stroke in patients with coronavirus disease 2019 (COVID-19) infection, but there is little information about the clinical course and outcomes these patients. Case Description: We report a case 36-year-old woman COVID-19 infection who developed like symptoms while under home quarantine. Cranial CT scan showed an left internal carotid artery (ICA) infarct. She subsequently underwent emergent DH....

Background: External ventricular drain (EVD) insertion is a common neurosurgical procedure used to treat acute hydrocephalus. In this report, we present rare case of an EVD that was initially correctly placed within the frontal horn but subsequently migrated cisterna magna, first be reported in literature. Case Description: A 46-year-old man with postoperative meningitis and hydrocephalus underwent using improvised system. The also as route for administration intraventricular antibiotics....

<title>Abstract</title> Purpose Ventriculoperitoneal shunt (VPS) insertion is the gold standard treatment for congenital hydrocephalus, but there little data about cost of this procedure in developing countries. We aimed to determine in-hospitalization initial VPS and its complications (malfunction infection) identify predictors increased cost. Methods performed a retrospective cohort study by reviewing medical financial records pediatric patients with hydrocephalus underwent surgery at our...

Objectives. To identify factors that predict the occurrence of seizures in patients with aneurysmal subarachnoid hemorrhage (SAH) and to evaluate efficacy antiepileptic drugs (AEDs) preventing in-hospital among who undergo clip occlusion ruptured intracranial aneurysms. Methods. In this retrospective study, medical charts 205 admitted for SAH Philippine General Hospital (PGH) underwent craniotomy clipping aneurysm from January 2011 June 2014 were reviewed.

Background: Arrested hydrocephalus is a condition wherein congenital spontaneously ceases to progress due balance between production and absorption of cerebrospinal fluid. These patients rarely present with pressure symptoms so conservative treatment may be instituted. There are, however, little data on the long-term outcomes these how they in presence other intracranial pathologies as transition into adulthood. We aim add growing knowledge about management arrested who have sustained...

Objective: Neurosurgical boot camps allow trainees to hone practical skills in a risk-free environment, but the models and simulators used are relatively costly. In developing countries like Philippines, low-cost alternatives have be devised. The authors aimed demonstrate feasibility of using local, readily available, inexpensive tropical fruits as surrogate for basic neurosurgical training during camp. Methods: Locally available were teach trainees. Coconut, pomelo, watermelon head clamp...

Cough is one of the most common symptoms coronavirus disease 2019 (COVID-19) infection. This relatively benign symptom may lead to serious sequelae, especially in postoperative neurosurgical patients.Here, we report a case bone flap displacement, pseudomeningocele formation, and consequent cerebrospinal fluid leak patient with COVID-19 infection who recently underwent craniotomy for excision cerebral metastasis. We highlight pathophysiologic mechanisms cough that cause increased intracranial...
