Smartphone-based clients are being increasingly used in a medical world for individual as well as group communications. The authors report the use of WhatsApp, a common social media smartphone client for neurosurgical referral service in their Institution. They extend the use of WhatsApp application from a purely intra-departmental informal communication to a formal tertiary referral service for Neurosurgical referrals. The pros and cons of deploying such system are discussed and important concerns are highlighted. ⋯ Smartphone-based social media clients such as WhatsApp provide a promising future for faster, reliable communication of clinical and radiological data, which can be used for on-call neurosurgical referrals. Integration with PACs applications and facial recognition may facilitate increasing use of such applications in future addressing many of the concerns that currently prohibit their universal use.

Meta Analysis
The incidence and treatment of seizures after cranioplasty: a systematic review and meta-analysis.
Patients surviving initial decompressive craniectomy are needed to undergo cranioplasty, which is potentially complicated by postoperative seizures. The definite incidence of post-cranioplasty seizures and application of prophylactic antiepileptic drugs remain controversial. ⋯ The estimated incidence of post-cranioplasty seizures is 43 per 1,000 person-years after adjustment. The incidence of early seizures is obviously higher than that of late seizures. Moreover, early cranioplasty leads to more post-cranioplasty seizures than late cranioplasty does. Based on the present evidences, the application of prophylactic antiepileptic drugs effectively reduces seizures.

Procedures to treat medically refractory trigeminal neuralgia (MRTN) include stereotactic radiosurgery (SRS) and microvascular decompression (MVD). The aim of this study was to compare outcomes of SRS versus MVD in the treatment of MRTN, with a subgroup focus on those being treated for the first time. ⋯ Both SRS and MVD alleviate pain in MRTN patients. MVD results in superior rates of short- and long-term pain relief, facial numbness and dysesthesia control, and less recurrence amongst those in whom pain freedom was achieved, at the cost of greater postoperative complications when compared to SRS. Although no significant difference was found in terms of the need for retreatment surgery, there was a trend towards less procedures favoring MVD. First treatment by either technique represents the overall trends reported.

Review Comparative Study
A systematic review of levetiracetam versus phenytoin in the prevention of late post-traumatic seizures and survey of UK neurosurgical prescribing practice of antiepileptic medication in acute traumatic brain injury.
Guidelines recommend 1 week of prophylactic phenytoin for post-traumatic seizures (PTS). Levetiracetam is gaining popularity as an alternative with a superior side-effect profile and may be suitable for extended use. We performed a systematic review comparing the efficacy of levetiracetam and phenytoin in reducing the incidence of late PTS. The secondary objectives were to compare their effects on the Extended Glasgow Outcome Scale (GOS-E) and length of stay. We also aimed to survey current prophylaxis prescribing practices. ⋯ While our review found no evidence of a difference in late seizure incidence, there is evidence of improved long-term outcomes with levetiracetam. Neither study used an extended course of levetiracetam or continuous electroencephalography. Further research which accounts for these factors is required for the development of guidelines which take levetiracetam into account. Our survey showed a lack of awareness of the potential harms of extended phenytoin use and a move towards levetiracetam.

Cauda equina syndrome (CES) is a condition with significant implications and medico-legal profile. The literature still lacks large primary studies to provide strong evidence for a robust management pathway. Statements from Neurosurgical and Spinal societies support early diagnosis and imaging but this has not resulted in any noticeable shift in referral pattern. We strongly feel the need for a nationally agreed, evidence-based referral pathway in practice. We present our large series and in-depth analysis of the referral pathway to provide strong evidence for more robust referrals and management. ⋯ As with previous studies we conclude that signs/symptoms are insufficient to identify tCES. Taking into consideration the improved outcome with early diagnosis, the importance of early scanning in diagnosing tCES, and the poor availability of OOH MRI scanning outside of neurosurgical units, we recommend a national policy of 24/7 MRI availability for cases of sCES at all hospitals with MRI scanners. This would remove the 87% of patients not requiring urgent surgery from an unnecessary and distracting referral process.
