Transsphenoidal surgery (TSS) was introduced into the Republic of Uzbekistan in 2005 and has been developing since then. The principal center for the management of all pituitary disease is a single site for a nation with a population of approximately 30 million. Results in surgery for Cushing disease are a marker of surgical technical skill in TSS. All previously published series come from the developed world, where sophisticated investigations and management are available. Many of these investigations are not available in Uzbekistan. ⋯ TSS for Cushing's Disease achieved an early remission of 68.7% (early morning cortisol of <50 nmol/L), although 4 patients relapsed.

We developed a functional brain analysis system that enabled us to perform real-time task-related electrocorticography (ECoG) and evaluated its potential in clinical practice. We hypothesized that high gamma activity (HGA) mapping would provide better spatial and temporal resolution with high signal-to-noise ratios. ⋯ Although this study included a small number of subjects, it showed real-time HGA mapping with the same setting and tasks under different conditions. This study demonstrates the clinical feasibility of real-time HGA mapping. Real-time HGA mapping enabled simple and rapid detection of language functional areas in awake craniotomy. The mapping results were highly accurate, although the mapping environment was noisy. Further studies of HGA mapping may provide the potential to elaborate complex brain functions and networks.

Among shunt complications, the postshunt slit ventricle (PSSV) and the postshunt craniosynostosis (PSCS) may be managed by shunt valve upgrade and/or cranial expansion surgery. Here, we analyzed 26 children with PSSV, PSCS, or microcephaly who received simple generalized cranial expansion (ie, total calvarial transsutural distraction osteogenesis [TC-TSuDO]). ⋯ We suggest that postshunt complications such as PSSV or PSCS, especially those that are accompanied by increased intracranial pressure or postshunt microcephaly, may be managed for patients with TC-TSuDO, which has been shown to be safe, simple, and effective.

The pituitary adenoma causing acromegaly is typically resected through a transsphenoidal approach and visualized with an operating microscope or endoscope. We undertook a systematic review and meta-analysis examining the clinical efficacy of endoscopic and microsurgical approaches. ⋯ Our study shows the clinical utility of the endoscopic approach and demonstrates potential benefits including increased remission rates with noninvasive macroadenomas and a lower rate of meningitis.

The prevalence of asymptomatic unruptured intracranial aneurysms (AUIA) in a Southeast Asian population has not been previously studied. Knowing the disease burden and population at risk can assist us in making informed decisions when managing AUIAs. We aimed to determine if the local prevalence of AUIAs differed from other populations in the published literature. ⋯ In this large cohort of a Southeast Asian population, the prevalence of AUIA was 3.5%. Most of the AUIAs were less than 5 mm and did not require intervention at time of discovery and did not progress within the year of follow-up.
