A new guide tube for odontoid screw fixation for unstable odontoid fractures: report of 6 case series.
We describe a modified form of traditional open surgery with a new guide tube. This guide tube permits anterior screwing of odontoid in a shorter time with a more simple technique as compared to traditional open surgery, endoscopic and percutaneous surgeries. MATERIAL and Our series includes 6 patie...
Pure intraventricular origin of gliosarcoma - a rare entity.
We report a very unusual case of an intraventricular non-parenchyhmal gliosarcoma in a 60-year old female. Magnetic resonance imaging of the brain revealed a well defined brilliantly enhancing mass located in the septal region and extending into the body and the frontal horn of the lateral ventricle...
Interscapular pharyngocutaneous fistula: an extreme complication of cervical stabilization surgery.
We report a 41-year-old paraplegic man with an interscapular pharyngocutaneous fistula secondary to cervical vertebral surgery. The diagnosis of posterior fistula was delayed for several months as it was an extremely rare complication. We explored the anterior neck and repaired the perforation on th...
Surgical management of intracranial arachnoid cysts: clinical and radiological outcome.
We retrospectively reviewed the medical records of 45 consecutive patients who underwent surgical drainage for symptomatic intracranial cysts at our institution from January 2000 to January 2010. The average age of our patients was 36.2 years; 26 were female and 19 were males. The most common sympto...
The effect of intracerebroventricular injection of beta amyloid peptide (1-42) on caspase-3 activity, lipid peroxidation, nitric oxide and N...
Intracerebroventricular (icv) administration of beta amyloid peptide (Aβ) in rats can be used to model certain aspects of Alzheimer disease (AD).The purpose of this study was to examine the effects of intracerebroventricular Aβ (1-42) peptide injection on caspase-3 activity and expression of nNOS an...
Intracranial blastomycosis presenting as an enhancing cerebellopontine mass.
Isolated Blastomyces dermatitidis infection of the central nervous system is an uncommonly encountered entity. If left untreated it can be fatal; thus accurate diagnosis in a timely manner is critical. A 37-year-old white male presented with a severe headache. An MRI scan revealed a right-sided enha...
Contralateral acute subdural hematoma after surgical evacuation of the initial hematoma: two case reports and review of the literature.
We presented two patients who developed contralateral acute subdural hematomas after surgical evacuation of their initial hematomas. Case 1: A 19-year-old male fell from a height. CT scan revealed a left parietal acute epidural hematoma. A left craniotomy and epidural hematoma evacuation were perfor...
Primary ewings sarcoma of cavernous sinus in an infant: a case report and review of literature.
We present clinical, radiological, pathological findings of Ewing's / pPNET involving the cavernous sinus in an eleven-month-old infant presenting with proptosis and 6th nerve palsy. MRI Contrast scans showed a well-defined, homogenously enhancing mass involving the right cavernous sinus...
Management of medically intractable genitofemoral and ilioingunal neuralgia.
To evaluate the effectiveness of invasive procedures in medically intractable genitofemoral and ilioingunal neuralgia. MATERIAL and This is a prospective study of 20 patients with genitofemoral and ilioinguinal neuralgias who were treated at our medical center between 2007 and 2011. Genitofemoral an...
Noninvasive estimation of cerebral perfusion pressure with transcranial Doppler ultrasonography in traumatic brain injury.
In traumatic brain injury (TBI) patients, to overcome the secondary insults, cerebral perfusion pressure (CPP) oriented therapy is recommended. The study is assigned to estimate CPP values with middle cerebral artery (MCA) flow velocities measured noninvasively using transcranial Dop...
