Neuroprotective Effects of Milrinone on Experimental Acute Spinal Cord Injury: Rat Model.

Objective: Spinal cord injury (SCI) disrupts nerve axons with devastating neurological consequences, but there is no effective clinical treatment. The secondary damage mechanism is a mainstay process, and it starts within a few minutes after trauma. We aim to investigate the neuroprotective effects of milrinone on the SCI model.

Beneficial effects of moxonidine on cerebral vasospasm after experimental subarachnoid hemorrhage.

Aim: This study was designed to examine the efficacy of moxonidine, a centrally acting antihypertensive agent that is a selective ligand for I1-imidazoline sites, in a rabbit cerebral vasospasm model.

Material And Methods: Twenty-four white, male New-Zealand rabbits weighing 2500-3200 gr. were randomly allocated into three groups as group 1= control group, group 2=subarachnoid hemorrhage (SAH) alone group, and group 3=SAH + moxonidine (treatment) group.

CSF hydrothorax after ventriculoperitoneal shunt without catheter migration: a case report.

Ventriculoperitoneal (VP) shunting is the most common procedure performed for the management of hydrocephalus. VP shunt related complications remain a persistent problem in current clinical practice. Five-year-old female patient was admitted to our hospital with persistent dyspnea complaint.

Lumboperitoneal shunt in a patient with Behçet's disease with medically refractory intracranial hypertension.

A 21-year-old male presented with severe throbbing headache, nausea, vomiting and progressive visual loss. Clinical examination revealed bilateral papilledema and left abducens nerve palsy. MRI showed findings consistent with dural sinus thrombosis.

N-acetylcysteine prevents vasospasm after subarachnoid hemorrhage.

Background: This study investigated the ability of NAC to prevent cerebral vasospasm in a rabbit model of SAH.

Methods: Twenty-one, male New Zealand white rabbits were randomly divided into 3 groups of 7 rabbits each: group 1 (control), group 2 (SAH only), group 3 (SAH + NAC treatment). NAC (150 mg/kg, single dose, IP) was administered just before SAH and continued until 72 hours after SAH in group 3.

Preventive effects of intraperitoneal selenium on cerebral vasospasm in experimental subarachnoid hemorrhage.

Vasospasm is an important cause of morbidity and mortality with subarachnoid hemorrhage (SAH). The effect of intraperitoneal administration of selenium, which is an antioxidant on cerebral vasospasm was investigated in an experimental model. By means of intracisternal blood injection model, SAH was induced in 24 rabbits, which were randomly divided into 3 groups (group 1= control group, group 2=SAH alone group, and group 3=SAH plus selenium group).

Anatomic and radiologic analysis of the atlantal part of the vertebral artery.

The horizontal third segment (V3h) of the vertebral artery (VA) in 7 cadavers (14 sides) was dissected and the anatomical measurements recorded. Measurements from 24 healthy individuals (48 sides) were taken for comparison using multislice CT scanning. The distance between the medial tip of the VA V3h and the line passing through the mid point of the posterior tuberculum of the atlas was marked as length A.

A case with prepontine (clival) arachnoid cyst manifested as trigeminal neuralgia.

Most cases of "idiopathic" trigeminal neuralgia are thought to originate from vascular compression of the trigeminal root entry zone. In this case, we describe a young man presenting with the symptoms of trigeminal neuralgia associated with a prepontine (clival) arachnoid cyst.

Astroblastoma in a child.

Background: Astroblastoma, an uncommon neuroepithelial tumor, typically presents in young adults as a well-circumscribed cortical or subcortical spherical mass. Astroblastoma may cause a diagnostic problem to anyone unfamiliar with its architectural and histological features.

Case History: We report the case of a 4-year-old boy who was referred for complaints of progressive deficits of balance and difficulty with walking during the previous 3 months.

Iatrogenic epidermal inclusion cyst of the parapharyngeal space: unusual complication of ear surgery.

A 46-year-old man presented with a 12-month history of a slow-growing mass at the right anterior temporal and superior parotid region. He had a history of chronic otitis media and had undergone a modified radical mastoidectomy for cholesteatoma 5 years earlier. Physical examination revealed a sinus tract and diffuse soft tissue mass measuring 4 cm in diameter spread throughout the region of the right anterior temporal and superior parotid areas.

The role of hyperbaric oxygen in the management of subarachnoid hemorrhage.

Objective: To determine the role of hyperoxic and hyperbaric therapy following experimental subarachnoid hemorrhage (SAH).

Design: Prospective, randomized, controlled animal study.

Subjects: Thirty male Wistar rats.

Lateral posterior fossa venous sinus relationships to surface landmarks.

Background: Knowing the location of the venous sinuses in the combined lateral posterior fossa and lateral cranial base approach is important to prevent their inadvertent injury. The identification of surface landmarks related to these structures is useful in planning such surgical approaches.

Methods: Twelve injected adult cadaver specimens and 10 dried skulls were used to study the relationship of the venous sinuses to various surface anatomic structures.

Arachnoid cyst within the fourth ventricle: a case report.

The authors report a case of fourth ventricular arachnoid cyst that presented clinically with the criteria of normal pressure hydrocephalus. Only a few cases of intraventricular arachnoid cyst have been recorded in the literature. In our case, a posterior approach was used via a midline suboccipital craniectomy and the cyst was excised.

Submandibular and intracranial hydatid cyst in an adolescent.

Objectives: An unusual case of hydatid disease is reported. Review of the pertinent literature did not reveal any hydatid disease located simultaneously in both the intracranial and submandibular glands. This is the first case with hydatid disease occurring in both locations at the same time.
