In the neurosurgery patient population, one of the most frequent complications is postoperative nausea and vomiting (PONV). The purpose of this predictive correlational study was to examine the incidence and predictors of PONV in a cohort of 519 neurosurgery patients undergoing elective spinal and intracranial procedures. Patients were interviewed, and their medical records were reviewed every 24 hours for up to 72 hours postoperatively to identify risk factors for PONV development. After summarizing univariate associations, a multivariable logistic regression model for each outcome was developed using forward and backward stepwise selection, with the p value for a variable to enter or leave the model set to ...

Brain surgery to promote behavioral or affective changes in humans remains one of the most controversial topics at the interface of medicine, psychiatry, neuroscience, and bioethics. Rapid expansion of neuropsychiatric deep brain stimulation has recently revived the field and careful appraisal of its 2 sides is warranted: namely, the promise to help severely devastated patients on the one hand and the dangers of premature application without appropriate justification on the other. Here, we reconstruct the vivid history of the field and examine its present status to delineate the progression from crude freehand operations into a multidisciplinary treatment of last resort...

Hemangioblastomas (HBMs) are highly vascular tumors of the central nervous system. Sporadic HBMs are nearly always solitary, and solitary HBMs are similar to intracranial arteriovenous malformations due to their highly vascular characteristics. However, to the best of our knowledge, cases of HBM in the cerebellum mimicking an aneurysm have never been reported in the literature. The present study reports a case of an HBM on the right cerebellar hemisphere mimicking an aneurysm, which originated from the right posterior inferior cerebellar artery, as determined using magnetic resonance angiography and digital subtraction angiography...

BACKGROUND: Trigeminal neuralgia (TN) is characterized by paroxysmal pain attacks affecting the somatosensory distributions of the trigeminal nerve. It is thought to be associated with a neurovascular conflict most frequently, but pathomechanisms have not been fully elucidated. In general, no sensory deficit is found in routine clinical examination. There is limited data available, however, showing subtle subclinical sensory deficits upon extensive testing. OBJECTIVE: We used quantitative sensory testing (QST) to detect abnormalities in sensory processing in patients with TN by comparing the affected and non-affected nerve branches with their contralateral counterparts and by comparing the results of the patients with those of controls...

China is currently the most populous and rapidly aging nation in the world. In the next few decades, China will have to increase the throughput, quality, and scope of its neurosurgical training programs in order to meet forecasted demand. Until recently, China lacked national education standards in neurosurgery that fostered imbalances in medical and pedagogical resources, quality of care, and education between different regions; and introduced significant heterogeneity in neurosurgical competency. In 2010, Shanghai implemented the first new standards-based comprehensive neurosurgery training program, which spans 7 years broken down into 2 blocks...

Schizophrenia is a chronic and progressive psychiatric disease that remains difficult to manage in the 21st century. Current medical therapies have been able to give reprieve and decrease incidence of psychotic episodes. However, as the disease progresses, patients can become ever more refractory to current pharmaceutical agents and the polypharmacy that is attempted in treatment. Additionally, many of these drugs have significant adverse effects, leaving the practitioner in a difficult predicament for treating these patients...

Pontificia Universidad Católica de Chile´s medical school was founded in 1929. Interest for neurosurgical development arose in the minds of the Dean, Dr. Cristobal Espíldora, and the Chief of Surgery, Dr. Rodolfo Rencoret in 1946. They encouraged and supported Dr. J. Ricardo Olivares to specialize in Neurosurgery with Professor H. Olivecrona in Stockholm, Sweden. The first neurosurgical procedure in the Hospital Clínico de la Universidad Católica was performed in 1950. Since then, intensive efforts have been made to develop Neurosurgery and its science...

Here, we report a case of vertebral artery aneurysm causing dysphagia in a 56-year-old man who had no remarkable past history. Two months before the first visit, he developed posterior neck pain followed by difficulty swallowing 1 month later. He was referred to our clinic because of gradually worsening dysphagia. Physical examination showed paralysis of cranial nerves IX, X, and XII; therefore, he was hospitalized. Because enhanced CT and MRI showed a partially thrombosed right vertebral artery aneurysm, he was transferred to the care of the Department of Neurosurgery...

BACKGROUND: Growth hormone secreting pituitary adenomas (somatotroph adenoma) predominantly express somatostatin receptors (SSTRs) subtypes 2 and 5. Higher SSTR2 expression on somatotroph adenomas results in a better response to somatostatin analogues (SSAs), which preferentially bind, but also down regulate, SSTR2. The effect of the combined treatment with SSAs and the GH receptor antagonist pegvisomant (PEGV) on SSTR expression in somatotroph adenomas is currently unknown. AIM OF THE STUDY: To assess SSTR2 and SSTR5 expression in three groups of somatotroph adenomas: drug-naive, treated with long-acting (LA) SSA monotherapy, or LA-SSA/PEGV combination therapy before surgery...

REVIEW
Timothy G Dyster, Charles B Mikell, Sameer A Sheth
The role of neuroimaging in psychiatric neurosurgery has evolved significantly throughout the field's history. Psychiatric neurosurgery initially developed without the benefit of information provided by modern imaging modalities, and thus lesion targets were selected based on contemporary theories of frontal lobe dysfunction in psychiatric disease. However, by the end of the 20th century, the availability of structural and functional magnetic resonance imaging (fMRI) allowed for the development of mechanistic theories attempting to explain the anatamofunctional basis of these disorders, as well as the efficacy of stereotactic neuromodulatory treatments...

Computer Aided Orthopaedic Surgery (CAOS) is now about 25 years old. Unlike Neurosurgery, Computer Aided Surgery has not become the standard of care in Orthopaedic Surgery. In this paper, we provide the technical and clinical context raised by this observation in an attempt to elucidate the reasons for this state of affairs. We start with a brief outline of the history of CAOS, review the main CAOS technologies, and describe how they are evaluated. We then identify some of the current publications in the field and present the opposing views on their clinical impact and their acceptance by the orthopaedic community worldwide...

Drug-resistant epilepsy seems like a different disease compared with easy to control epilepsy, and new strategies are needed to help these patients. Vagus nerve stimulation (VNS) therapy is the most frequently used neurostimulation modality for patients with drug-resistant epilepsy who are not eligible for seizure surgery. In this study, we aimed to evaluate the efficacy and adverse effects of VNS in patients with drug-resistant epilepsy in an open-label, prospective, long-term study in Iran. We selected 48 patients with partial-onset drug-resistant epilepsy...
