We report a patient with medically refractory mesial temporal lobe epilepsy treated by gamma knife radiosurgery. In lieu of a microsurgical procedure, an entorhinoamygdalohippocampectomy was performed with a gamma knife and low marginal doses (25 Gy). The clinical and imaging studies, including CT, MR imaging, 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), and long-term follow-u...

Tumors of the endolymphatic sac are locally invasive temporal bone neoplasms. Radical surgical excision is the treatment of choice; however, the aggressive nature of these tumors can make total excision impossible. Recurrence is common in cases of incomplete resection. Gamma knife radiosurgery was used to treat two patients with primary tumors of the endolymphatic sac and one recurrent case. Al...

The understanding of pattern formation in Drosophila requires the handling of the many genetic and molecular interactions which occur between developmental genes. For that purpose, a knowledge base (KNIFE) has been developed in order to structure and manipulate the interaction data. KNIFE contains data about interactions published in the literature and gathered from various databases. These dat...

introduction: gamma knife is an instrument specially designed for treating brain disorders. in gamma knife, there are 201 narrow beams of cobalt-60 sources that intersect at an isocenter point to treat brain tumors. the tumor is placed at the isocenter and is treated by the emitted gamma rays. therefore, there is a high dose at this point and a low dose is delivered to the normal tissue surroun...

introduction the gamma knife system is designed solely for non-invasive treatment of brain disorders, and it benefits from stereotactic surgical techniques. dose calculations required in the system are performed by gammaplan code; in this code, brain tissue is considered uniform. in the present study, we evaluated the effect of gamma knife system on the obtained dose through simulating a real h...

A 38-year-old man presented to a regional Western Australian hospital after being stabbed in his left eye with a knife. Computerized Tomography (CT) revealed a 7 cm knife blade within the globe extending along the skull base. After transfer to a tertiary hospital, a cerebral angiogram was performed, excluding significant cerebral vascular involvement. Through a multidisciplinary approach with t...

The Leksell Gamma Knife [Elekta Corp] uses helmets as collimators to produce four standard beam sizes. The nominal beam diameters are 18, 14, 8, and 4 mm. During computer treatment planning for gamma knife stereotactic radiosurgery, the size of the treated volume may differ from the standard beam sizes. To maintain conformality of the isodose curves to the treated volume, beam sizes may be supe...

BACKGROUND Although the prone position providing better exposure for anorectal surgery is required it can cause a reduction of cardiac output and cardiac index. The goal was to compare haemodynamic changes assessed by impedance cardiography during anorectal surgery under low-dose spinal anaesthesia in lithotomy and jack-knife position. METHODS The prospective randomized controlled study inclu...

Three varieties of wheat and knife bevel angles, four levels of moisture content and three shearing speeds of pendulum were considered to determine their effects on the shearing energy of wheat straw. Results showed that the effects of variety, knife bevel angle, moisture content and shearing speed on shearing energy were significant (P<0.01). Shearing energy decreased with decreasing moisture ...
