Neurofibromatosis type 1 (NF1) is a multisystemic hereditary disorder associated with an increased risk of benign and malignant tumor formation predominantly on the skin, bone, and peripheral nervous system. It has been reported that out of all the NF1 cases, more than 95% cases develop the disease due to heterozygous loss-of-function variants in Neurofibromin (NF1) gene. However, identification of NF1 causative variants by presently recommended method of gene-targeted Sanger sequencing is challenging and cost-intensive due to the large size of the NF1gene with 60 exons spanning about 350 kb.

Article Synopsis
  • The study aimed to evaluate the effectiveness and safety of clobazam as an add-on therapy for patients with epilepsy whose seizures were not well-controlled by single antiseizure medications (ASM).
  • Conducted in India, the research followed 429 patients over one year, assessing seizure control and adverse effects through interviews and diaries.
  • Results showed that 83.4% of the patients remained seizure-free after one year, and clobazam was well-tolerated, although 22.6% experienced adverse events.

Article Synopsis
  • Leigh Syndrome (LS) is a rare hereditary disorder affecting infants or young children, characterized by diverse clinical symptoms and complications in diagnosis due to genetic diversity.
  • A case study is presented of a 9-year-old boy with atypical LS features, including Bilateral Basal Ganglia Calcification and a longer-than-usual survival age, linked to a novel variation in the MT-ATP6 gene.
  • The study emphasizes the importance of combining neuro-imaging techniques and Next Generation Sequencing to accurately diagnose atypical cases of LS.

Manifestations of primary hypoparathyroidism are produced by neuromuscular irritability or by extraosseous calcifications. We present a patient of primary hypoparathyroidism who had extensive calcification of brain parenchyma, and was suffering from chronic, generalised and progressive stiffness of body due to cervical compressive myelopathy, caused by calcification of posterior longitudinal ligament and ligamentum flavum. By presenting this case we wanted to emphasize the usefulness of meticulous clinical examination to differentiate the stiffness caused by myelopathy from that which is caused by possible coexisting extrapyramidal disorder.

Pantothenate kinase-associated neurodegeneration is a rare hereditary neurodegenerative disorder associated with nucleotide variation(s) in mitochondrial human Pantothenate kinase 2 (hPanK2) protein encoding PANK2 gene, and is characterized by symptoms of extra-pyramidal dysfunction and accumulation of non-heme iron predominantly in the basal ganglia of the brain. In this study, we describe a familial case of PKAN from the State of Jammu and Kashmir (J&K), India based on the clinical findings and genetic screening of two affected siblings born to consanguineous normal parents. The patients present with early-onset, progressive extrapyramidal dysfunction, and brain Magnetic Resonance imaging (MRI) suggestive of symmetrical iron deposition in the globus pallidi.

Celiac disease is considered to be rare in parts of the world where rice is a staple cereal. Kashmir is one of such places. We present an adult Kashmiri man, who had peripheral neuropathy, which turned out to be associated with celiac disease and improved remarkably with total elimination of gluten containing foods.

We report identification and genetic characterization of a rare skeletal disorder that remained unidentified for decades in a village of Jammu and Kashmir, India. The population residing in this region is highly consanguineous and a lack of understanding of the disorder has hindered clinical management and genetic counseling for the many affected individuals in the region. We collected familial information and identified two large extended multiplex pedigrees displaying apparent autosomal recessive inheritance of an uncharacterized skeletal dysplasia.

Churg-Strauss syndrome (CSS) is a rare cause of vasculitic neuropathy. Although rare and potentially fatal, Churg-Strauss syndrome (CSS) is easily diagnosable and treatable. The presence of bronchial asthma with peripheral neuropathy in a patient alerts a physician to this diagnosis.

Vitamin D is increasingly recognized to have several beneficial effects. Its toxicity, causing hypercalcemia, is considered as extremely rare. We report case series of 15 patients (most of them being elderly subjects) with iatrogenic symptomatic hypercalcemia in whom toxicity occurred due to empirical excessive administration of vitamin D by oral and parenteral route.

Objective: To determine the prevalence of major neurological disorders in children less than 10 years of age.

Materials And Methods: The study was conducted in the framework of a population based, single centre, cross-sectional study at Ranbir Singh Pura town, 22 km south-west of Jammu city.

Results: Eight cases of active epilepsy with a crude prevalence rate of 202 (95% confidence interval [CI] 180-220), five cases of Febrile seizures with a crude prevalence of 126 (95% CI 110-140) and eleven cases of cerebral palsy with a crude prevalence rate of 277 (95% CI 245-309) per 100,000 were found.

Background: Mishriwala is one of five exclusive clusters of Kashmiri migrants established in 1990 to accommodate Kashmiri Pandit families who left Kashmir valley in the wake of militancy. Mishriwala migrant camp has seen minimal immigration and out-migration since its establishment. In an earlier study we reported on the prevalence of dementia amongst a Kashmiri migrant population.

Neurocysticercosis (NCC) is caused when the cysticercus larvae of Taenia solium infect the central nervous system. The larvae usually land in the parenchymal tissue, but quite rarely can lodge in the ventricles and cisterns of the brain. Unlike parenchymal NCC, it is not easy to demonstrate the cysticercus cysts within the cerebrospinal fluid spaces.
