To investigate the association between immunologic counts on admission and acute symptomatic hydrocephalus after aneurysmal subarachnoid hemorrhage (aSAH). ⋯ Neutrophil count ≥9.80 × 103/mL on admission predicts acute symptomatic hydrocephalus after aSAH in an adjusted multivariate logistic regression model. Moreover, shunt dependence was associated with higher neutrophil counts.

Percutaneous vertebroplasty (PVP) is widely used for treatment of osteoporotic vertebral compression fractures (VCFs). However, the influence of PVP timing (early vs. late) on development of adjacent vertebral fractures has rarely been discussed. This retrospective cohort study aimed to evaluate bone-cement binding for thoracolumbar fractures (T8-L3) using a new assessment method to predict risk for adjacent vertebral fractures. ⋯ Axial computed tomography images were used to characterize bone-cement binding properties. Patients who underwent early PVP had a lower MSI, better bone-cement integration, and fewer adjacent fractures.

Improving the gross total resection (GTR) rate of suprasellar pituitary macroadenomas (SPMAs) using the pure endoscopic endonasal transsphenoidal approach (EETA) has been a long-standing focus of neurosurgeons. This study was aimed at evaluating the influences of the removal of the tuberculum sellae bone (TSB) without opening the dura of the tuberculum sellae on the GTR rate of SPMAs via the EETA. ⋯ TSB removal using EETA without opening the tuberculum sellae dura improves the GTR rate of SPMAs without increasing the incidence of postoperative complications.

Spinal metastases occur primarily in the thoracic spine (50%-60%), less commonly in the lumbar (30%-35%), and, infrequently, in the cervical spine (10%-15%). There has been only 1 study with a limited population comparing the postoperative outcome among cervical, thoracic, and lumbar spine metastasis. The aim of this study is to identify whether the region of surgically treated spinal metastasis affects postoperative outcomes. ⋯ The postoperative outcomes of patients undergoing surgery for metastases are not affected by the region of the spine.

Dropped head syndrome is a morbid condition that affects daily functionality, causing pain and dysphagia and respiratory compromise. Reported causes of dropped head syndrome include neuromuscular disorders, iatrogenic from cervical spine surgery, and idiopathic and postradiation for head and neck cancers. Management of this spinal disorder remains challenging, as the complication rates are high. We present our series of 7 patients who underwent surgical correction of dropped head syndrome, all resulting from radiation for head and neck cancers. ⋯ Surgical correction of postradiation dropped head spinal deformity involving anterior and posterior fixation with osteotomies provides improvement in functional and radiographic outcomes as shown in our series. These cases are technically challenging and have a high rate of perioperative complications. Approaches must be tailored to the patient with attention to their specific surgical and radiation history.
