ReviewGlobal hydrocephalus epidemiology and incidence: systematic review and meta-analysis.
Hydrocephalus is one of the most common brain disorders, yet a reliable assessment of the global burden of disease is lacking. The authors sought a reliable estimate of the prevalence and annual incidence of hydrocephalus worldwide. ⋯ For the first time in a global model, the annual incidence of pediatric hydrocephalus is estimated. Low- and middle-income countries incur the greatest burden of disease, particularly those within the African and Latin American regions. Reliable incidence and burden figures for adult forms of hydrocephalus are absent in the literature and warrant specific investigation. A global effort to address hydrocephalus in regions with the greatest demand is imperative to reduce disease incidence, morbidity, mortality, and disparities of access to treatment.

ReviewThe global neurosurgical workforce: a mixed-methods assessment of density and growth.
In 2000, the global density of neurosurgeons was estimated at 1 per 230,000 population, which remains the most recent estimate of the global neurosurgeon workforce density. In 2004, the World Health Organization (WHO) estimated that there were 33,193 neurosurgeons worldwide, including trainees. There have been no updates to this estimate in the past decade. Moreover, only WHO region-level granularity regarding neurosurgeon distribution exists; country-level estimates are limited. The neurosurgery workforce is a crucial component to meeting the growing burden of neurosurgical diseases, which not only represent high absolute incidences and prevalences, but also represent correspondingly high disability-adjusted life years affecting hundreds of millions of people worldwide. Combining the lack of knowledge about the availability of the neurosurgical workforce and the increasing demand for neurosurgical services underscores the need for a system of neurosurgical workforce density surveillance. ⋯ In 2015, the Lancet Commission on Global Surgery estimated that 143 million additional surgical procedures are needed in low- and middle-income countries each year, and a subsequent study revealed that approximately 15% of those surgical procedures are neurosurgical. Based on our results, we can conclude that there are approximately 49,940 neurosurgeons currently, worldwide. The availability of neurosurgeons appears to have increased in all geographic regions over the past decade, with Southeast Asia experiencing the greatest growth. Such remarkable expansion should be assessed to determine factors that could play a role in other regions where the acceleration of growth would be beneficial.

ReviewAn estimation of global volume of surgically treatable epilepsy based on a systematic review and meta-analysis of epilepsy.
Epilepsy is one of the most common neurological disorders, yet its global surgical burden has yet to be characterized. The authors sought to compile the most current epidemiological data to quantify global prevalence and incidence, and estimate global surgically treatable epilepsy. Understanding regional and global epilepsy trends and potential surgical volume is crucial for future policy efforts and resource allocation. ⋯ Understanding of the global epilepsy burden has evolved as more regions have been studied. This up-to-date worldwide analysis provides the first estimate of surgical epilepsy volume and an updated comprehensive overview of current epidemiological trends. The disproportionate burden of epilepsy on low- and middle-income countries will require targeted diagnostic and treatment efforts to reduce the global disparities in care and cost. Quantifying global epilepsy provides the first step toward restructuring the allocation of healthcare resources as part of global healthcare system strengthening.

ReviewTiming of surgery in traumatic brachial plexus injury: a systematic review.
Ideal timeframes for operating on traumatic stretch and blunt brachial plexus injuries remain a topic of debate. Whereas on the one hand spontaneous recovery might occur, on the other hand, long delays are believed to result in poorer functional outcomes. The goal of this review is to assess the optimal timeframe for surgical intervention for traumatic brachial plexus injuries. ⋯ The results of this systematic review show that in stretch and blunt injury of the brachial plexus, the optimal time to surgery is shorter than 6 months. In general, a 3-month delay appears to be appropriate because while recovery is better in those operated on earlier, this must be considered given the potential for spontaneous recovery.

Pain surgery is one of the historic foundations of neurological surgery. The authors present a review of contemporary concepts in surgical pain management, with reference to past successes and failures, what has been learned as a subspecialty over the past 50 years, as well as a vision for current and future practice. This subspecialty confronts problems of cancer pain, nociceptive pain, and neuropathic pain. ⋯ TN is a mainstay of the surgical treatment of pain, particularly as new evidence and insights into TN emerge. Pain surgery will continue to build on this heritage, and restorative procedures will likely find a role in the armamentarium. The challenge for the future will be to acquire higher-level evidence to support the practice of surgical pain management.
