Abstract Background Meningiomas are the most common CNS tumors and majority is regarded as benign. However, a subset of patients presents with complex involving several anatomic compartments skull base - eluding any concepts gross total resection. Proton therapy (PT) applied definitive treatment for primary or recurrent disease postoperatively following subtotal We report on first 100 adult tre...

Quantifying how the sound delivered to the ear canal relates to hearing threshold has historically relied on acoustic calibration in physical assemblies with an input impedance intended to match the human ear (e.g., a Zwislocki coupler). The variation in the input impedance of the human ear makes such a method of calibration questionable. It is preferable to calibrate the acoustic signal in eac...

Background: Despite improvements in the safety and efficacy of endovascular procedures, considerable morbidity may still be attributed to vasospasm. Vasospasm has proven amenable to pharmacological intervention such as nitrates, intravenous calcium channel blockers (CCBs), and intra-arterial papaverine, particularly in small vessels. However, few studies have focused on medium to large vessel s...

PURPOSE To compare dose reconstruction accuracy with different oblique beam angles when 2d detector arrays are used for small field IMRT QA. METHODS 2D detector arrays are convenient to use but their low resolution limits the number of sampling points inside small radiation fields. In this study, we demonstrate that with oblique beam incidence, more points can be measured and 3D dose volume c...

treatment of patient with high anal fistulas has become complicated and post-operative complications are common. the aim of this study was to evaluate post-operative complications of primary sphincter’s repair technique in patients with high anal fistula. an interventional quasi-experimental study was conducted on 60 patients(42 male & 14 female) with high anal fistula. the most frequent age gr...
