To test which intracerebral hemorrhage (ICH) characteristics impact incidence of hydrocephalus and characterize subsequent impact on outcomes. ⋯ Bleed characteristics affect incidence of hydrocephalus on admission, rates of long-term shunt dependency, and outcomes. Hemorrhage location did not predict shunt dependency; however, it did predict outcomes. Specifically, cerebellar ICH was associated with a better discharge mRS score.

Cushing disease (CD) is a rare clinical disease in which brain structural and function are impaired as the result of excessive cortisol. However, little is known whether rich-club organization changes in patients with CD, as visualized on resting-state magnetic resonance imaging (fMRI), can reverse to normal conditions after transsphenoidal surgery (TSS). In this study, we aimed to investigate whether the functional connectivity of rich-club organization is affected and whether any abnormal changes may reverse after TSS. ⋯ Our results show rich-club organization was disrupted in patients with active CD with excessive cortisol production. TSS can reverse abnormal rich-club connectivity. Rich club may be a new indicator to investigate the outcomes of TSS and to increase our understanding of the effect of excessive cortisol on brain functional connectivity in patients with CD.

Ossified posterior longitudinal ligament (OPLL) of the cervical spine can lead to spinal stenosis and become clinically symptomatic. The optimal approach in addressing OPLL is a debated topic and dependent on factors such as preoperative lordosis and levels affected. ⋯ All 3 approaches in the management of OPLL were associated with clinical improvement without 1 approach surpassing the others. Laminoplasty had the advantage of addressing more levels of stenosis than the anterior approach and was associated with a shorter operating time. Laminoplasty patients had a shorter hospital stay than those undergoing laminectomy and instrumentation and appeared to have fewer complications than the other approaches. Laminoplasty is the preferred approach in patients with preserved motion and lordosis, with the anterior approach effective in the correction of kyphosis.

Comprehensive Diagnosis and Surgical Management of Cushing's Disease: 2-Dimensional Angiographic and Operative Video.
Cushing disease (CD), or hypercortisolemia secondary to an adrenocorticotropic hormone-secreting (ACTH-secreting) pituitary adenoma, is the most common etiology of noniatrogenic Cushing syndrome.1 The diagnostic algorithm employed in the patient with suspected CD is complex and includes consideration for inferior petrosal sinus sampling (IPSS).2,3 When workup is consistent with CD, extracapsular resection of the ACTH-secreting pituitary adenoma through the endonasal corridor is the preferred operative strategy.4 In this publication, we discuss the case of a 26-year-old woman who presented with 9 months of weight gain (Video 1). Initial labs, including low- and high-dose dexamethasone suppression tests, were consistent with CD. Findings on dynamic magnetic resonance imaging were suggestive of a left 2-mm microadenoma. ⋯ Following surgery, the patient required glucocorticoid supplementation after her cortisol levels decreased to 2 ug/dL the evening of surgery. Subsequent laboratory analysis has been consistent with hormonal cure.5,6 The accompanying video manuscript describes 1) preoperative diagnostic evaluation of the patient with suspected CD, 2) indications for and techniques of IPSS, 3) nuances of endoscopic transsphenoidal surgical management, and 4) relevant considerations in postoperative care. Of note, full patient consent for photography and/or recording of other forms of video/imaging was obtained in the preoperative period.7-10.

Lost to follow-up (LTF) represents an understudied barrier to effective management of chronic subdural hematoma (cSDH). Understanding the factors associated with LTF after surgical treatment of cSDH could uncover pathways for quality improvement efforts and modify discharge planning. We sought to identify the demographic and clinical factors associated with patient LTF. ⋯ Uninsured and Medicaid patients had a greater likelihood of LTF compared with private insurance and Medicare patients. LTF was further associated with an increased risk of neurosurgical readmission. The results from the present study emphasize the need to address barriers to follow-up to reduce readmission after surgery for cSDH. These findings could inform improved discharge planning, such as predischarge repeat imaging studies and postdischarge contact.
