There is minimal data within the literature demonstrating the use of robotics to resect pelvic, benign schwannoma(s). Herein, we describe a case of a 46-year-old transgender male that presented with complaints of left-sided pelvic pain. Pre-operatively, the etiology was unknown. The patient underwent robotic-assisted laparoscopic excision of the pelvic mass, including a 5-6 cm resection of the obturator nerve, successfully. Final pathology found a benign schwannoma. Schwannomas are difficult to diagnose pre- and intra-operatively and are thus frequently misdiagnosed as urologic or gynecologic lesions...

INTRODUCTION: Vertical root fracture inevitably leads to tooth extraction. Thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. This study aimed to assess the fracture resistance of roots following the application of different sealers including Epiphany, iRoot sealer and AH-plus. METHODS AND MATERIALS: Fifty extracted human single-canal premolars without caries, curvature or cracks were used in this study...

BACKGROUND: The PROSPECT (Procedure-Specific Postoperative Pain Management) Group recommended a single injection femoral nerve block in 2008 as a guideline for analgesia after total knee arthroplasty. Other authors have recommended the addition of sciatic and obturator nerve blocks. The lateral femoral cutaneous nerve is also involved in pain syndrome following total knee arthroplasty. We hypothesized that preoperative blocking of all four nerves would offer superior analgesia to femoral nerve block alone...

BACKGROUND AND PURPOSE: Although there is a strong biological rationale to electively treat the pelvic nodes during bladder preservation, its clinical benefit is uncertain. This may be explained by the incidental dose received by the nodal regions when treating the bladder alone. This study was conducted to investigate the doses received by the different pelvic nodal regions when the bladder alone is treated by standard conformal radiotherapy. METHODS AND MATERIALS: The computed tomography data sets of 20 patients with node-negative muscle-invasive bladder cancer treated in a bladder preservation protocol were studied...

REVIEW
Amanda K Hartnack
In food animals, spinal cord damage is most commonly associated with infection or trauma. Antemortem diagnosis is based on clinical signs, history, cerebrospinal fluid analysis, and imaging. As clinical signs are often severe, and prognosis is grave, necropsy may provide a postmortem diagnosis. Peripheral nerve abnormalities are most often the result of trauma. Calving paralysis or paresis is the most common condition affecting the sciatic or obturator nerve and often concurrently involves the peroneal branch of the sciatic...
