In sum, this study reveals a detrimental role of Hsp90 inhibition in podocyte injury, which may offer it as a potential therapeutic target in NS therapy. Although primary cilia abnormalities have been frequently observed in multiple cancers, including prostate cancer (PCa), the molecular mechanisms underlying primary ciliogenesis repression in PCa cells remain unclear. Transforming acidic coiled-coil protein-3 (TACC3), whose deregulation has been implicated in the pathogenesis of several types of cancer, is a key centrosomal protein that plays a crucial role in centrosome/microtubule dynamics, potentially impacting primary cilium generation. Here, we showed that TACC3 was markedly upregulated in PCa and that knockdown of TACC3 restrained tumorigenesis and tumor growth in vitro and in vivo. Additionally, we found that TACC3 interacts with filamin A, and elevated levels of TACC3 disrupted the interaction between filamin A and meckelin, thereby restraining primary cilium formation in PCa cells. This video presents the surgical management of a 36-year-old woman who presented with progressive weakness in her right arm associated with a pins-and-needles sensation. Magnetic resonance imaging of the cervical spine revealed a likely hemorrhagic cavernous malformation of the spinal cord at the C3-4 level. The lesion was wholly intramedullary with no presentation to the surface of the spinal cord. It was located in the spinal cord centrally with some right-side predominance. Treatment options were presented to the patient, who agreed to surgery. A resection was performed after a hemilaminotomy at C3 and C4 levels. A biportal technique was used, demonstrating resection of the malformation through 2 small myelotomies made between the entering rootlets at the dorsal root entry zone. This was intended to preserve all roots at the entry zone while enabling visualization of the entire cavernous malformation and its cavity from 2 different portals of entry, essentially providing the same field of access while preserving all roots. After successful resection, the cavity was carefully inspected and closure of the dura was performed, followed by fixation of the osteotomy sites of the laminae at C3 and C4. The patient awoke with no new neurological deficits and has had no evidence of lesion recurrence or symptoms in 3-year follow-up. The patient provided consent for publication. BACKGROUND Gunshot wound (GSW) injuries are among the leading causes of penetrating spinal column injury (pSI). pSI patients often have concurrent polytrauma that complicate management. METHODS We retrospectively reviewed charts between January 2012 to June 2018 at an urban Level 1 Trauma Center and analyzed bracing and surgical indications, antibiotic and MRI use, and patient outcomes. RESULTS We identified 100 pSI patients with an average age of 27.2 years (range 15-58). Five patients had knife injuries and 95 suffered GSW. Polytrauma occurred in 90% of patients with an average of 3.39 bullets per patient (range 1-23). Fourteen patients underwent either decompressive surgery (n=8) or decompression and fusion (n=6). Thirty-five patients were externally braced. 43% of patients presented as ASIA-A compared to 26% who were intact. While 14 patients received prophylactic antibiotics for retained bullets or durotomies, only two patients had postoperative wound infections and four had extraspinal infections from retained bullets. All inpatient mortalities (n=5) were patients with cervical pSI. Thirteen GSW patients obtained MRI scans without complications. Among our cohort, only 65 patients had followup with a median followup period of 1.25 (range 1-60) months. CONCLUSIONS Management of pSI in urban trauma centers is complex, as these victims routinely have polytrauma that take precedence. Indications for surgical intervention are narrow and secondary to surgery for polytrauma. External bracing may be overutilized. The efficacy of prophylactic antibiotics remains unclear. MRI can contribute valuable information but is limited by uncertainty regarding bullet compatibility. Lack of follow-up limits study of this population. BACKGROUND and importance Unclippable vertebral artery aneurysms (UVAs) are difficult to treat with direct clipping, especially in cases involving the origin of the posterior inferior cerebellar artery (PICA). Bypass with trapping is the common procedure used for these conditions. The authors used the blind-alley formation technique, which is a simpler method than trapping and can avoid some complications. OBJECTIVES To report seven cases of UVA with PICA involvement treated with blind-alley formation and occipital artery-posterior inferior cerebellar artery (OA-PICA) bypass as well as their surgical outcomes and complications and to describe the operative techniques. RESULTS Seven patients with UVA and PICA involvement underwent OA-PICA bypass and blind-alley formation (occlusions of the PICA origin and vertebral artery proximal to the aneurysm). Vertebral artery dissecting aneurysms and fusiform atherosclerotic vertebral artery aneurysms were detected in 6 patients and 1 patient, respectively. All patients presented with subarachnoid hemorrhage, and 71.4% of them were classified into the poor-grade group. GSK2126458 datasheet Good bypass patency and complete aneurysm obliteration were achieved in all cases. Six aneurysms (85.7%) were completely obliterated according to computed tomography angiography performed immediately postoperatively. Another aneurysm was 50% and 100% thrombosed immediately and at seven days after the operation, respectively. Surgical complications were found in 1 patient (14.3%) who had postoperative diparesis with dysphagia. Three patients (42.9%) achieved a Glasgow Outcome Score (GOS) of 4 or 5 1 month after the operation. CONCLUSIONS Blind-alley formation and OA-PICA bypass are simple, safe and effective for the treatment of UVA patients with PICA involvement. BACKGROUND One of the merits of exoscopes, including ORBEYE, is that they are superior to a microscope in terms of ergonomic features. We report a case of dural arteriovenous fistula (dAVF) that was cured by direct surgery utilizing the ergonomic advantages of ORBEYE. CASE DESCRIPTION A 78-year-old man was found to have dAVF of the anterior cranial fossa incidentally. We performed direct surgery via bifrontal craniotomy. As the frontal sinus was large, we reserved the frontal bone like "eaves" in order not to open the frontal sinus. The vertex of his head was sufficiently down to shift the frontal lobe downward with gravity. During surgery, we set the angle of the operative visual axis of ORBEYE approximately horizontal to avoid the reserved frontal bone. We performed a stable operation using ORBEYE in a comfortable posture. CONCLUSIONS ORBEYE facilitates ergonomic microsurgery, even "under the eaves", with the angle of the operative visual axis approximately horizontal utilizing gravity.
