AIM To probe into problems existing in gamma knife treatment of ophthalmic branch of primary trigeminal neuralgia (TN), and propose a safe and effective solution to the problem. METHODS Through sorting the literature reporting gamma knife treatment of refractory TN in recent years, this article analyzed the advantages and problems of gamma knife treatment of primary TN, and proposed reasonabl...

BACKGROUND The predominant treatment modality for meningioma is surgical resection. However, gamma knife radiosurgery is also an important treatment modality for meningioma that is small or cannot be completely removed because of its location. In this study, we evaluated the effectiveness and long-term results of radiosurgical treatment for meningioma in our institution. METHODS We studied 62...

Docking by knife or elastrator had no sustained effect on growth of lambs 0 to 8 wk postpartum. However, during the 2 wk period postdocking, growth of lambs was limited or depressed, regardless of whether lambs were docked by knife at 14, 28 or 42 d of age. Blood hematocrit and hemoglobin were decreased (P less than .01) 1 d after docking by knife and 14 d after docking by elastrator. Neither m...

The base sledge microtome presents a hazard to the operator due to the length of blade that is exposed. Manipulation of the carriage requires hand movements close to the knife edge and serious lacerations may result. A simple, effective guard has been devised, suitable for knives which have screw holes for handles at both ends. It consists of two perspex end-pieces (Fig. I), attached to the kni...

OBJECTIVE To describe cases of intra-orbital knife blade foreign body following stabs to the orbit, together with a novel technique for removal. METHODS Retrospective case series of 3 patients. RESULTS All 3 patients had knife blades embedded in the orbit as a result of assault. The blades assumed the same direction within the orbit with varying degrees of depth, one causing serious vascula...

The Gamma Knife Check software is an FDA approved second check system for dose calculations in Gamma Knife radiosurgery. The purpose of this study was to evaluate the accuracy and the stability of the commercial software package as a tool for independent dose verification. The Gamma Knife Check software version 8.4 was commissioned for a Leksell Gamma Knife Perfexion and a 4C unit at the Univer...

This paper proposes a cake-cutting protocol using cryptography when the cake is a heterogeneous good that is represented by an interval on a real line. Although the Dubins-Spanier moving-knife protocol with one knife achieves simple fairness and truthfulness, all players must execute the protocol synchronously. Thus, the protocol cannot be executed on asynchronous networks such as the Internet....

Standard treatment of cerebral alveolar hydatid disease consists of open brain surgery and systemic albendazole. We describe a patient with inoperable cerebral alveolar hydatid cysts on whom gamma knife radiosurgery was used instead of open brain surgery. Because of the size of the multicystic lesion, the gamma knife procedure was done in two sessions. Repeated courses of albendazole were given...
