BACKGROUND Radiotherapy is the primary treatment for nasopharyngeal carcinoma, and temporal lobe necrosis is observed in about 7% of patients after radiotherapy. Although some studies reported that these patients demonstrated cognitive impairment after radiotherapy, it is still unclear if the cognitive deficits are related to the radiation exposure or the(More)
We demonstrate mode-division multiplexed WDM transmission over 50-km of few-mode fiber using the fiber's LP01 and two degenerate LP11 modes. A few-mode EDFA is used to boost the power of the output signal before a few-mode coherent receiver. A 6×6 time-domain MIMO equalizer is used to recover the transmitted data. We also experimentally characterize the(More)
The role of Sonic hedgehog (shh) in neural crest development was initially suggested by its involvement in patterning of the neural tube. While largely implicated in cell fate determination during development, its recently discovered role in the development of neurons postnatally prompted the possibility that neural crest derivatives of the sympathoadrenal(More)
PURPOSE To review the clinical outcomes of patients with voiding dysfunction who have detrusor overactivity with impaired contractility (DOIC) diagnosed with urodynamic studies. METHODS Urodynamic reports from 2005 to 2009 were reviewed, and 54 male patients had findings consistent with DOIC. Patients with acontractile or neuropathic bladders were(More)
The efficacy of intravesical onabotulinumtoxinA (BTXA) in the treatment of overactive bladder (OAB) has been well documented. The use of BTXA injection in orthotopic neobladders is yet to be studied. We present 4 cases of patients injected with intravesical BTXA for overactive orthotopic ileal neobladder. We recorded patient demographics, presenting and(More)
PURPOSE To investigate the efficacy and safety of repeated botulinum toxin type-A (BTX-A) injections for patients with drug-refractory nonneurogenic overactive bladder (NNOAB) and explore factors predictive of outcome. METHODS Data were collected from all patients receiving repeated BTX-A injections for drug-refractory NNOAB between 2004 and 2012.(More)
PURPOSE Traditional implantation of the AMS Sphincter 800 Urinary Control System (American Medical Systems, Minnetonka, Minnesota) requires 2 incisions. The cuff is placed via a perineal incision, and the pressure regulating balloon and pump are placed through a separate suprapubic incision. We describe a novel implantation of all the artificial urinary(More)
Ependyma-lined cystic lesions of the subarachnoid space are uncommon. They form a histologically heterogeneous group and have been referred to as epithelial, ependymal, glioependymal and neuroepithelial cysts depending on their respective histological characteristics. In this report, we describe two cases of ependyma-lined cysts in the posterior fossa that(More)
We report a 74-year-old woman and a 50-year-old woman with similar histories of headache and visual disturbance who were found to have adamantinomatous craniopharyngiomas which contained melanin pigment. This finding was confirmed by the Masson Fontana method and ultrastructural studies. These are only the second and third cases reported describing melanin(More)
