OBJECTS: Meningioma is the most common intracranial neoplasm, comprising approximately 30% of all primary intracranial tumors (Claus et al., 2005) [1]. Treatment options include observation, microsurgical resection, stereotactic radiosurgery (SRS), and whole brain radiation therapy (WBRT). Gamma knife radiosurgery (GKRS) is a very effective treatment for intracranial meningiomas; previous studies showed the tumor control rate at 5-10 years of follow-up as 84.3%-100% in all cases (Feigl et al...

Ryan Vealey, Antoun Koht, Bernard Bendok
In some cases of cerebral aneurysm clipping, direct clip application to the aneurysm neck may be difficult or the aneurysm may rupture unexpectedly. In these cases, a clip may be temporarily applied to the parent artery to reduce aneurysmal wall tension, facilitate permanent clip placement, or control bleeding if the aneurysm ruptures. In certain circumstances, even applying a temporary clip may be challenging. We present a case in which the aneurysm ruptured and IV administration of adenosine was required to facilitate clipping...

K Hamm, H-U Herold, G Surber, S Rosahl
Management of vestibular schwannoma (VS) should always be interdisciplinary and results better than the natural course. Particularly in small VS, either microsurgical resection or radiosurgery (RS) can be employed. RS is a special method (initially only possible stereotactically) for delivering high-precision radiation from many directions to the target point (the isocenter) in a single high dose. With the development of three different systems-Gamma Knife (Elekta, Stockholm, Sweden), special linear accelerators, and CyberKnife (Accuray, Sunnyvale, CA, USA)-the options were extended to 1-5 fractions for RS and multisession RS (msRS), and to up to 6 weeks of conventional fractionation as stereotactic radiotherapy (SRT)...

REVIEW
Patrick Whelan, Laurence Levine
Varicocele is most often surgically repaired due to male infertility, however, has recently been linked to low serum testosterone. This paper serves to review the current literature regarding varicocele and its subsequent repair on serum testosterone. Twenty-eight human studies were identified with fifteen showing improved serum testosterone after repair. The majority of the studies that demonstrated improvement had preoperative testosterone levels that were low or below normal. Additionally, multiple well-designed studies with control groups not undergoing surgical repair demonstrated significant difference between groups...

OBJECTIVES: Surgical trauma produces metabolic and hormonal responses, which are characterized by insulin resistance. Due to extension of the preoperative fasting period, which increases the magnitude of postoperative insulin resistance, preoperative oral carbohydrates (POC) have been developed. PATIENTS AND METHODS: This prospective, randomized, controlled study was performed on 43 ASA I-II patients undergoing elective microsurgical lumbar discectomy. The intervention group received oral carbohydrate solution 800mL the night before and 400mL 2h prior to operation...

Intraventricular cavernomas (IVCs) are extremely infrequent and only occur in 2.8 to 10% of patients with cerebral cavernomas. We describe three IVC cases and briefly review previously documented IVC cases in PubMed. Among 136 IVC cases, the mean age of the patients was 36.5 years; the male-to-female ratio was 0.8. The most frequent location was the lateral ventricle (52.6%), and most of the clinical symptoms (74%) were related to mass effects on adjacent brain tissues. Intraventricular hemorrhage occurred in 22...

Chang Il Choi, Kyung Chae Park, Tae Ho Lee, Young Kwon Hong
BACKGROUND/PURPOSE: The purpose of the study was to determine if testicular delivery during microsurgical subinguinal varicocelectomy (MSV) reduces varicocele recurrence rates in pediatric patients. Testicular delivery during MSV enables ligation of the gubernacular veins, which is thought to reduce the likelihood of varicocele recurrence. However, recent studies have suggested that testicular delivery during MSV does not offer any beneficial effect and, therefore, may be optional or unnecessary...

Microsurgical reconstructive techniques have revolutionized the treatment of large head and neck defects. These defects were once forever life altering because of the considerable morbidity to both the form and function of the patient. As time has progressed, microsurgical technique has improved dramatically and has become institutionalized in our training programs. Free flap outcomes in head and neck reconstruction have improved dramatically, and optimization of these outcomes is now key. One overlooked area has been neurosensory reconstruction...

PURPOSE: The neurotomy of musculocutaneous nerve is a treatment for patients who suffer from spastic elbow flexion when medical and reeducative treatments have failed. It consists in sectioning motor branches of musculocutaneous nerve which are destined to the biceps brachii and brachialis muscles, both being the main elbow flexor muscles. The aim of this study was to analyse the distance, where each motor branch arises from the musculocutaneous nerve to both biceps brachii and brachialis muscles, to establish precisely the localisation and length of the necessary incision to reach its branches for surgery...
