Most spinal meningiomas are intradural lesions in the thoracic spine that present with both local pain and myelopathy. By using large prospective Surveillance, Epidemiology, End Results (SEER) database, authors studied incidence of examined demographic treatment factors predictive death.Using SEER*Stat software, queried SEER database for cases meningioma between 2000 2010. From results, tumor statistics were computed; was analyzed as a function location, pathology, age, sex, malignancy code....
Intradural spinal hemangioblastoma are infrequent, vascular, pathologically benign tumors occurring either sporadically or in association with von Hippel-Lindau disease along the neural axis. Described fewer than 1,000 cases, literature is variable respect to epidemiological factors associated and their treatment. The objective of this study was evaluate epidemiology intradural Surveillance, Epidemiology End Results (SEER) database while also presenting an illustrative case.The SEER queried...
OBJECTIVE The lack of access to primary neurosurgical care presents a significant burden for patients in low- and middle-income countries (LMICs). Efforts decrease the inequities surgical have become an increasing focus initiatives advocacy within international neurosurgery community. Although residents may represent highly active members teams, extent their availability interest global opportunities remains unclear. objectives this study were assess degree participation, level interest,...
Anterior sacral meningoceles (ASMs) are rare defects in the sacrum with thecal sac herniations and symptoms that commonly include constipation, dysmenorrhea, urinary disturbances. An ASM causing hydronephrosis acute renal failure from compression of lower portion tract is a clinical entity. Only one other case has been reported. The authors present 37-year-old man admitted for obstructive due to giant measured 25 × 12 18 cm compressed ureters bladder. was successfully treated via an anterior...
Posttraumatic amnesia is superior to the initial Glasgow Coma Scale score for predicting traumatic brain injury recovery, but it takes days/weeks assess. Here, we examined whether return of visual fixation-a potential marker higher cognitive function-within 24 hours ICU admission could be used as an early predictor recovery.Two-phase cohort study.Level-I trauma ICU.Moderate-to-severe discharged alive between 2010 and 2013.None.Return fixation was assessed through standard behavioral...
Intraventricular rupture of a colloid cyst is rare phenomenon and has been proposed as mechanism for sudden death in patients with cysts. Imaging during described only one other instance. The authors report highly unusual case 53-year-old man who presented acute onset headaches imaging findings hydrocephalus caused by originating from the septum pellucidum superior surface roof third ventricle. Interestingly, revealed signs intraventricular characterized tail-like drainage cystic contents...
Abstract In this work, we employed Raman spectroscopy to study the effect of antimicrobial peptide lactoferricin B (LfB) on model cell membranes. We used two derivatives LfB (RRWQWRMKKLG and RRWQWR) with broad‐spectrum activity against gram‐positive gram‐negative bacteria, fungus, viruses tumors. spectra peptides showed no conformational change in temperature range 4–60 °C. The positions amide I III bands suggest that an aqueous solution these preferentially adopt a random coil‐like...
Ossification of the posterior longitudinal ligament (OPLL) and cervical disc herniation are commonly encountered neurosurgical conditions. Here we present an unusual case nontraumatic rapidly progressive myelopathy due to with comorbid OPLL conduct a literature review focusing on frequency management herniations OPLL.A 52-year-old healthy female presented 72-h history rapid progression dense quadriparesis sensory deficits, precedent 4-week midline neck pain. Clinical examination revealed...
Surgical treatment options are limited for medically and endovascular refractory cerebral venous sinus thrombosis (CVT).

Spontaneous spinal epidural hematoma (SSEH) is a rare condition that typically associated with hypertension, the use of antithrombotic or sympathomimetic drugs. Here, we report case SSEH attributed to amphetamines.A 27-year-old amphetamine user presented sudden onset paraplegia (Frankel A) following use. An MRI revealed C7-T2 cord compression due an hematoma. Following negative angiogram, was removed, and patient markedly recovered. Notably, by exclusion, etiology for amphetamines.Here,...
Mesothelioma is a relatively rare tumor arising from the pleura, most notably associated with exposure to asbestos. Typically, mesothelioma locally aggressive poor outcome in order of months time diagnosis. Although cases distant metastases have been documented literature, this has less reported than other malignancies chest, and identified autopsy studies, likely related short survival times patients harboring these tumors.
Atlantoaxial sublaminar wiring has many known complications related to hardware failure, but intracranial hemorrhage is a rare complication.A 61-year-old female patient with prior atlantoaxial for odontoid fracture nonunion experienced decreased level of consciousness due subarachnoid and subdural the posterior fossa intraventricular extension hydrocephalus. Rupture wire intramedullary protrusion was cause hemorrhage. The treated ventriculostomy hydrocephalus occipital cervical fusion spinal...
