Cerebrotendinous Xanthomatosis, a Treatable Disorder Often Missed: Case Series of Three Patients Confirmed by Genetic Testing.

ABSTRACT: Cerebrotendinous xanthomatosis (CTX) is a treatable autosomal recessive disorder with varied clinical manifestations and age of onset and is often diagnosed late. We report three cases of CTX who presented at our center with clinical features of frequent diarrhea, early cataracts, xanthomas, cognitive decline, ataxia, neuropathy, and other manifestations of CTX. Magnetic resonance imaging (MRI) brain in all three patients revealed abnormalities consistent with CTX. Diagnosis was confirmed by next-generation sequencing. Chenodeoxycholic acid (CDCA) is recommended as the drug of choice, as it can halt the disease progression and reverse some of the symptoms. In addition to late diagnosis, nonavailability of CDCA in our part of world adds to the problem of management of such patients; therefore, they are often started on alternative therapies, which are less effective.

Miller Fisher syndrome associated with COVID 19.

Miller Fisher syndrome (MFS), is an acute peripheral neuropathy, a variant of Guillain-Barre syndrome, that develops following exposure to different viral, bacterial, and fungal pathogens. Patients usually present with a triad of ophthalmoplegia, ataxia, and areflexia. During Covid pandemic MFS has been described associated with novel coronavirus disease 2019 (COVID-19). Here we describe the clinical course, Cerebrospinal fluid (CSF) findings, nerve conduction studies, treatment and outcome of the patient having MFS concurrent with COVID 19.

A study on the clinical, epidemiological profile and the outcome of the snake bite victims in kashmir valley.

Background: India is estimated to have the highest snakebite mortality in the world. In India, around 250,000 incidents of snake bite are reported annually with 50,000 deaths. There are about 236 species of snakes in India, most of which are nonpoisonous. Most snakes found in Kashmir valley are nonvenomous of colubridae family (ptyas mucosus or grass snake). Materials and Methods: This Hospital-based retrospective and prospective study was conducted at Sher-i-kashmir Institute Of Medical Sciences Srinagar, a multispeciality teaching hospital having clinics for various medical and surgical specialities. All snake bite patients admitted in department of Emergency Medicine, other specialities, and critical care medicine were taken in this study over a period of 3 years. Results: Among a total of 108 cases of snake bite, majority were males (57.40%) and mostly 20 to 50 years of age (68.51%).Majority of victims were from rural areas (93.5%) and most of the bites occurred during day time (87.96%) mainly on the lower limbs (63.88%). Highest number of cases occurred from May to October (98.14%). Most of the victims were farmers. Bleeding was present in 13.88% patients and coagulopathy ( International normalized ratio (INR)>1.2) in 63.88% of patients. Neuroparalytic features were present in 8.33% patients. Mortality in our study was 2.8%. Conclusion: Snake bite in our valley is an occupational hazard affecting working class engaged in farming in fields, fruit orchards, and forests in rural areas. There is seasonal variation with most envenomations occurring in peak months of agricultural activities. Non recommended first aid measures like tourniquet and incision are commonly encountered. Regular public health programmes regarding prevention, prehospital management (first aid), and immediate transfer to hospital should be emphasized.

Interleukin 32 gene promoter polymorphism: A genetic risk factor for multiple sclerosis in Kashmiri population.

OBJECTIVE: Although the exact cause of multiple sclerosis is not known, there are a number of factors involved mainly environmental and genetic factors. The present study was done to determine association between IL-32 gene promoter polymorphism and IL-32 levels with multiple sclerosis. METHODS: 48 relapsing remitting multiple sclerosis patients and 60 healthy controls were compared for IL-32 gene promoter polymorphism and IL-32 levels. RESULTS: There was no significant difference in genotype CT between the MS patients and healthy controls (p 0.130) where as a significant difference in genotype (CC) frequencies among MS patients and healthy controls (p 0.039) was observed. The difference in C allele frequency was also statistically significant between two study groups (p 0.01). Multivariate regression analysis revealed that the CC genotype might impact the risk of disease susceptibility up to 3.71 times and the presence of C allele might increase the risk of susceptibility to multiple sclerosis by 2.26 fold. The serum IL-32 levels were not statistically different multiple sclerosis patients and healthy controls and between wild and mutant genotypes. CONCLUSIONS: IL-32 gene promoter polymorphism is a genetic risk factor for multiple sclerosis patients particularly women.

Isolated neurobrucellosis-characteristic clinical and laboratory features.

To report various neurological syndromes, CSF findings, imaging and diagnostic methods used in neurobrucellosis patients admitted in our Neurology department over a period of 6 years. Case records of patients admitted to our department from August 2014 to May 2020 were searched for neurobrucellosis and data were obtained. A total of 19 patients were diagnosed as neurobrucellosis over a period of 6 years. Ten patients had chronic meningitis, five had VIII nerve involvement, one had optic neuritis, two had acute meningitis, one had subacute meningitis, four had myelopathy, five had polyradiculitis and two had spondylodiscitis. CSF was abnormal in 17 patients. Neutrophilic pleocytosis was seen in 12 patients who included nine patients with chronic symptomatology. Brain imaging was abnormal in three chronic meningitis patients. One had diffuse meningeal enhancement, another had hydrocephalus while the third patient had meningeal enhancement with basal exudates and contrast enhancement of bilateral VIII nerve. One of the patients of acute meningitis had hydrocephalus while the other one had bilateral T2/FLAIR hyperintensities with enhancement of meninges and leptomeningeal vessels. Elevated antibody titers only in serum was seen in six patients while elevated antibody titers only in CSF was seen in seven patients. Four patients had elevated antibody titers in both serum and CSF. CSF culture was positive in three patients. Neurobrucellosis is a rare clinical complication of brucellosis but may pose a problem in diagnosis as it can mimic tuberculosis. Involvement of VIII nerve and neurophilic pleocytosis in CSF despite chronic symptomatology can be diagnostic clues favoring neurobrucellosis.
