Adjacent Level Tuberculous Spondylodiscitis Leading To Proximal Junctional Kyphosis: Rare And Unusual Presentation.
Vertebral osteomyelitis manifesting as a compression fracture misdiagnosed in the setting of steroid-induced or senile osteoporosis is very rare, although such patients are prone to infection or reactivation, as their immune system is exhausted. Spondylodiscitis occurring at adjacent levels following instrumented spinal fusion leading to pathologic fracture and proximal junctional failure, especially caused by tuberculosis, to our knowledge, has not been discussed in the literature. ⋯ Adjacent segment spondylodiscitis should be suspected and intraoperative biopsy must be considered for histopathologic and microbiologic examination to rule out subclinical infection in immunosuppressed patients with multiple comorbidities. Management should be individualized, considering the context of infection, causative organism, extent of bone destruction, and neurologic involvement.

Observational Study
Defects in processes of care for pharmacologic prophylaxis are common among neurosurgery patients who develop in-hospital, post-operative venous thromboembolism (VTE).
Venous thromboembolism (VTE) is a cause of considerable morbidity and mortality in hospitalized patients. An evidence-based algorithm was developed and implemented at our institution to guide perioperative VTE prophylaxis management. ⋯ Our evidence-based VTE prophylaxis algorithm was not accurately completed in more than half of patients. Many patients who developed VTE had a defect in their VTE prophylaxis management during their inpatient stay. Research to improve optimal VTE prevention practice in neurosurgery patients is needed.

Aneurysm wall enhancement (AWE) may predict rupture-prone intracranial aneurysms (IAs). However, the clinical and morphologic risk factors related to AWE have not been well described. Furthermore, the risk factors related to enhancement patterns have never been studied, especially in patients with anterior circulation aneurysms. Therefore, we aimed to investigate the risk factors related to wall enhancement and the enhancement patterns in anterior circulation unruptured aneurysms. ⋯ AWE was strongly associated with aneurysm size and was observed more frequently in symptomatic unruptured IAs. Sex hormones and atherosclerotic factors may be involved in circumferential enhancement. However, further studies should be performed to investigate the pathologic mechanisms for pattern of enhancement.

Dermoid cysts are benign congenital tumors that develop early in life. These tumors are classified by the presence of all 3 germ layers. Spinal intradural extramedullary teratoma is a rare disease, which is more common in children under 5 years of age than in adults. ⋯ Although dermoid cysts are uncommon, they should be considered in the differential diagnosis of spinal lesions in patients with lower back pain. It can be successfully treated with surgical excision.

Negative pressure wound therapy (NPWT) for deep spinal wound infections after exposure or opening of the dura can carry significant risks (i.e., cerebrospinal fluid infections and fistulas). In the present study, we reviewed a fairly large and recent experience with such patients. ⋯ NPWT can be safely applied for deep spinal wound infections after dura exposure or durotomy during previous spine surgery.
