Telemetry in intracranial pressure monitoring: sensor survival and drift.
Telemetric intracranial pressure (ICP) monitoring enable long-term ICP monitoring on patients during normal day activities and may accordingly be of use during evaluation and treatment of complicated ICP disorders. However, the benefits of such equipment depend strongly on the validity of the recordings and how often the telemetric sensor needs to be re-implanted. This study investigates the clinical and technical sensor survival time and drift of the telemetric ICP sensor: Raumedic Neurovent-P-tel. ⋯ In most cases, the ICP sensor provides reliable measurements beyond the approved implantation time of 90 days. Thus, the sensor should not be routinely removed after this period, if ICP monitoring is still indicated. However, some sensors showed technical malfunction prior to the CE-approval, underlining that caution should always be taken when analyzing telemetric ICP curves.

Predicting extent of resection in transsphenoidal surgery for pituitary adenoma.
The extent of resection (EOR) is a crucial outcome parameter in transsphenoidal pituitary surgery (TSS), and is linked to endocrinological outcome, postoperative morbidity, and mortality. We aimed to build a robust, quantitative, and easily reproducible imaging score able to predict EOR in TSS. ⋯ The proposed score is a simple and reproducible tool which reliably predicts surgical outcome including EOR, RV, and GTR of pituitary adenoma patients undergoing TSS.

Case ReportsDouble nerve transfer for restoration of hand grasp and release in C7 tetraplegia following complete cervical spinal cord injury.
Cervical spinal cord injury (SCI) can cause tetraplegia. Nerve transfer has been routinely utilized for reconstruction of hand in brachial plexus injuries. Here, we report reconstruction of finger flexion (hand grasp) and extension (hand release) in a victim of cervical spinal cord injury with tetraplegia. ⋯ We used double nerve transfer, namely brachialis branches of musculocutaneous nerve to anterior interosseous nerve (AIN) and supinator branch of radial nerve to posterior interosseous nerve (PIN). We found that brachialis nerve transfer to AIN (for finger flexion) and supinator branch nerve transfer to PIN (for finger extension) can provide finger flexion and extension simultaneously. Brachialis nerve transfer to AIN and supinator branch nerve transfer to PIN may be an acceptable surgical technique to restore hand grasp and release in tetraplegia after SCI.

Successful recovery of sensation loss in upper brachial plexus injuries.
Injuries of the upper trunk of the brachial plexus may trigger motor and sensory deficits. There exists a growing body of literature with respect to the reconstruction of motor deficits in upper trunk brachial plexus injuries by using nerve transfers; albeit to date, very few old reports have focused on the reconstruction of sensory loss resulting from upper trunk injuries. In this case series, we review six cases (five males and one female) with upper trunk brachial plexus injuries undergoing sensory nerve transfers. ⋯ These results suggest that nerve transfers can achieve satisfactory outcomes in patients having sensory reconstruction after upper brachial plexus injuries, and thus, we lay emphasis on reviving the use of sensory nerve transfer techniques in such patients.

Multicenter Study Observational StudyModalities and accuracy of diagnosis of external ventricular drainage-related infections: a prospective multicentre observational cohort study.
Device infection is a major complication of placement external ventricular drains (EVD). Diagnostic features are often masked by underlying disease or cerebrospinal fluid (CSF) contamination by blood. We aim to assess which diagnostic modalities are applied for EVD-related infection (ERI) diagnosis and evaluate their accuracy. ⋯ Clinicians base their diagnosis of ERI mostly on CSF analysis and occurrence of fever, leading to over-diagnosis. The accuracy of the clinical diagnosis is low. Commonly used clinical and laboratory diagnostic criteria have a low sensitivity and specificity for ERI.
