    Multicentric gliomas are uncommon pathological entities, although well described in the literature. The aim of this study was to highlight the management issues in a rare case of multicentric glioma occurring in a bilateral temporo-insular region. A 35-year-old farmer with no comorbid illness presented with a history of progressively increasing holocranial headaches, intermittent episodes of vomiting, and memory disturbances from the last 3 months. Radiological findings were suggestive of multicentric glioma involving bilateral temporo-insular regions. Patient underwent tumor decompression first on the left side followed by the right side. Postoperative course was uneventful. Management of multicentric gliomas is challenging.

    To study the clinico-radiological profile of children with acute leukoencephalopathy with restricted diffusion.

    A retrospective chart review of children with acute leukoencephalopathy with restricted diffusion was done from July 2015 to July 2018. The clinical details, neuroimaging findings, sequelae, and the final outcome on modified Rankin Score were analyzed.

    Sixteen children with a mean age of 4.4 years were diagnosed with acute leukoencephalopathy with restricted diffusion. All, except one, had fever, seizure, and altered sensorium. The median duration of hospital stay was 3 weeks. Only one out of 16, had biphasic clinical picture that is characteristic of acute encephalopathy with biphasic seizures and restricted diffusion. Magnetic resonance imaging showed restriction diffusion in all. While it was symmetric in 13 children, in 3 children it was asymmetric, and in 2 children there was patchy involvement. find more Seven children (43.7%) had post-encephalopathic epilepsy. While complete neurological recovery was seen in 2 children, behavioral problems like hyperactivity in 10 (62.5%), speech problems in 8 (50%), and cognitive delay in 3 (18.8%) children were noted.

    Acute leukoencephalopathy with restricted diffusion is emerging as an important cause of acute encephalopathy in children with a protracted course and long-term sequelae such as cognitive impairment and refractory postencephalopathic epilepsy.

    Parkinson’s disease (PD) is a multifaceted illness affecting ~ 0.3% of the world population. The genetic complexity of PD has not been, fully elucidated. Several studies suggest that mitochondrial DNA variants are associated with PD.

    Here, we have explored the possibility of genetic association between mitochondrial haplogroups as well as three independent SNPs with PD in a representative east Indian population.

    The Asian mtDNA haplogroups M, N, R, B, D, M7, and 3 other SNPs 4336 T/C, 9055 G/A, 13708 G/A were genotyped in 100 sporadic PD patients and 100 matched controls via conventional PCR-RFLP-sequencing approach.

    The distribution of mtDNA haplogroups, as well as 3 single polymorphisms, did not show any significant differences (P > 0.05) between patients and controls.

    This is the first of its kind of study from India that suggests no association of selected mitochondrial DNA variations with PD.

    Freezing of gait (FOG) is a disabling and refractory symptom of advanced Parkinson’s disease (PD). Interleaved stimulation (ILS) is a novel paradigm which may benefit axial symptoms of PD.

    To assess the effect of ILS on FOG in patients unresponsive to conventional subthalamic nucleus (STN) stimulation.

    19 PD patients receiving subthalamic stimulation and experiencing FOG at both conventional (130-150Hz) and low frequency (60Hz) stimulation were given ILS.The primary outcome measure was the UPDRS part III gait score (item 29) at 3 months after ILS. A subset of patients was tested with the stand-walk-sit (SWS) test, 30 min after ILS.

    The mean UPDRS part III gait score (baseline 1.8 ± 0.6) improved at 30 min (1.1 ± 0.8, P = 0.017) and remained improved at 3 months (1.2 ± 0.8, P = 0.048). FOG episodes reduced during SWS test (P = 0.041).

    ILS of STN through two adjacent contacts provided significant short-term beneficial effects on FOG.

This report describes six patients of histologically verified ML-PACNS. The mean age was 44.5 years (range 25-68) and four were males. Presenting symptoms headache (5), focal neurologic deficits (5), and seizures (4). On magnetic resonance imaging (MRI) the lesion was unifocal in two and multifocal in four patients. Consistent radiological findings were mass lesions with heterointense internal morphology with areas of diffusion restriction (DWI), and variable post-contrast enhancement. Pathologically vasculitis was classified as Granulomatous in one, necrotizing in two and lymphocytic in three. There were two deaths. In conclusion patients with ML-PACNS are likely to be younger and more likely to present with seizures. MRI lesions with hetrointense internal morphology with areas of DWI was a consistent finding and may be a clue for the diagnosis of ML-PACNS.

    Ventriculoperitoneal shunt (VPS) is the most common procedure used in the management of hydrocephalus regardless of the etiology. The standard free-hand technique is used for the placement of VPS in patients with enlarged ventricles. In patients with very small ventricles, CSF access through ventriculostomy becomes challenging and free-hand technique may be associated with high failure rates. In these situations, stereotactic-guided VPS becomes very useful.

    To validate and describe the technique of robotic-guided VPS in cases with very small ventricles.

    Three patients underwent VPS with robotic guidance between 2016 and 2019. One patient with a diagnosis of occipital meningocele, who later developed recalcitrant CSF leak from the operative site, and two other patients were diagnosed with idiopathic intracranial hypertension (IIH). Plain CT brain with 1-mm slice thickness acquired prior to the surgery was uploaded into the ROSA machine (Zimmer Biomet Warsaw, Indiana). The trajectory for the VPS is created on the robotic software presurgery.
