Hypopituitarism after Gamma Knife radiosurgery for pituitary adenomas: a multicenter, international study
Recurrent or residual adenomas are frequently treated with Gamma Knife radiosurgery (GKRS). The most common complication after GKRS for pituitary adenomas is hypopituitarism. In the current study, the authors detail the timing and types of hypopituitarism in a multicenter, international cohort of pituitary adenoma patients treated with GKRS. ⋯ Hypopituitarism remains the most common unintended effect of GKRS for a pituitary adenoma. Treating the target volume at an isodose line of 50% or greater and avoiding whole-sellar radiosurgery, unless necessary, will likely mitigate the risk of post-GKRS hypopituitarism. Follow-up of these patients is required to detect and treat latent endocrinopathies.

Gastrostomy tube placement increases the risk of ventriculoperitoneal shunt infection: a multiinstitutional study.
Gastrostomy tube placement can temporarily seed the peritoneal cavity with bacteria and thus theoretically increases the risk of shunt infection when the two procedures are performed contemporaneously. The authors hypothesized that gastrostomy tube placement would not increase the risk of ventriculoperitoneal shunt infection. The object of this study was to test this hypothesis by utilizing a large patient cohort combined from multiple institutions. ⋯ Gastrostomy tube placement significantly increases the risk of ventriculoperitoneal shunt infection.

Improving health care transition and longitudinal care for adolescents and young adults with hydrocephalus: report from the Hydrocephalus Association Transition Summit.
The health care needs of children with hydrocephalus continue beyond childhood and adolescence; however, pediatric hospitals and pediatric neurosurgeons are often unable to provide them care after they become adults. Each year in the US, an estimated 5000-6000 adolescents and young adults (collectively, youth) with hydrocephalus must move to the adult health care system, a process known as health care transition (HCT), for which many are not prepared. Many discover that they cannot find neurosurgeons to care for them. ⋯ Best practices were identified, including the National Center for Health Care Transition Improvement's "Six Core Elements of Health Care Transition 2.0"; development of hydrocephalus-specific transition programs or incorporation of hydrocephalus into existing general HCT programs; and development of specialty centers for longitudinal care of adults with hydrocephalus. The lack of formal HCT and longitudinal care for young adults with hydrocephalus is a significant health care services problem in the US and Canada that professional societies in neurosurgery and neurology must address. Consensus recommendations of the Hydrocephalus Association Transition Summit address 1) actions by hospitals, health systems, and practices to meet local community needs to improve processes and infrastructure for HCT services and longitudinal care; and 2) actions by professional societies in adult and pediatric neurosurgery and neurology to meet national needs to improve processes and infrastructure for HCT services; to improve training in medical and surgical management of hydrocephalus and in HCT and longitudinal care; and to demonstrate the outcomes and effectiveness of HCT and longitudinal care by promoting research funding.

Contralateral progression after unilateral evacuation of bilateral chronic subdural hematomas: the volume relation ratio as prognostic factor?
Unilateral evacuation of bilateral chronic subdural hematomas (bcSDHs) is associated with higher retreatment rates than an initial bilateral intervention. One reason for that is a possible progression in the size of the contralateral side after unilateral treatment. Thus, the authors focused their study on finding predictors of the need for contralateral retreatment. ⋯ Patients needing evacuation of bcSDHs should be considered for primary bilateral evacuation if the hematoma volume on the smaller side is greater than 40 cm3 and the subsequent volume relation ratio is greater than 0.4.

Using artificial neural networks to identify patients with concussion and postconcussion syndrome based on antisaccades.
Artificial neural networks (ANNs) have shown considerable promise as decision support tools in medicine, including neurosurgery. However, their use in concussion and postconcussion syndrome (PCS) has been limited. The authors explore the value of using an ANN to identify patients with concussion/PCS based on their antisaccade performance. ⋯ This study explored the utility of ANNs in the diagnosis of concussion/PCS based on antisaccades. With the use of an ANN, modest accuracy was achieved in a small cohort. In addition, the authors explored the pearls and pitfalls of this novel approach and identified important future directions for this research.
