Tuberculous meningitis (TBM) is an endemic infectious disease in developing countries, and it can become a serious illness in children. Treatment of TBM is more difficult and prone to failure than treatment of pulmonary tuberculosis. TBM causes hydrocephalus, cerebral edema, increased intracranial pressure, global ischemia, and neurologic deficits, which disturb cellular metabolism and increase lactate levels. A reliable, widely available clinical indicator of TBM severity is needed. Successful treatment of TBM is assessed using the Glasgow Outcome Scale (GOS). ⋯ Examination of plasma and CSF lactate levels should be included in routine examinations to determine extent of cellular damage and GOS score in patients with TBM and acute hydrocephalus who have undergone fluid diversions.

Review Meta Analysis
Association Between IDH1 and IDH2 Mutations and Preoperative Seizures in Patients with Low-Grade Versus High-Grade Glioma: A Systematic Review and Meta-Analysis.
Patients with brain tumors, particularly gliomas, commonly present with seizures. Higher incidence of seizure has been reported in low-grade gliomas and tumors located within the temporal and insular area. The association between IDH1 and IDH2 mutations with preoperative seizures in glioma and the magnitude of this association in low-grade versus high-grade gliomas are unclear. To clarify this relationship, a systematic review and meta-analysis was performed. ⋯ This study demonstrated a significant association of IDH1 and IDH2 mutations with incidence of preoperative seizures. This association was significant only in patients with low-grade glioma (grade II) and not in patients with higher grade gliomas (grade III and IV).

Patients with bitemporal lobe epilepsy are generally not considered for surgical resection. Fortunately, responsive neurostimulation provides another avenue for the management of this challenging disease process. In conjunction with our epileptologist, we consider responsive neurostimulation for patients who have clinical features of temporal lobe epilepsy without clear localization on imaging and stereoelectroencephalography. ⋯ Robotically implanted responsive neurostimulation is a safe and effective treatment for bitemporal epilepsy and can possibly lead to valuable diagnostic information to guide future surgical management in patients who previously were not considered candidates for resective or ablative surgery.

Dural substitutes are used in decompressive craniectomy (DC) to prevent adhesions during subsequent cranioplasty. Current literature attributes them to reduced blood loss and reduction in operative time of cranioplasty. The use of double-layer substitute has rarely been documented. We studied the use of double-layer G-patch as a dural substitute in DC and evaluated its outcome during subsequent cranioplasty with special focus on flap elevation time and blood loss during cranioplasty. ⋯ While evaluating the use of dural substitute during DC as an adhesion preventive material for subsequent cranioplasty, flap elevation time and blood loss should be taken into account rather than operative time. Double-layer G-patch during DC facilitates subsequent cranioplasty by preventing adhesions between the layers, resulting in easier dissection and reduced blood loss.
