Variations in the position of the bifurcation of the common carotid artery (CCA) and the origin or branching pattern of the external carotid artery are uncommon. Variations in transformation of the embryonic aortic arch system are the genesis of these variations. A 70-year-old female presented with history of sudden onset dizziness followed by right hemiparesis showed a trifurcation of CCA on carotid duplex ultrasound (CDU) scan. Computed tomography angiography (CTA) of the extracranial neck vessels confirmed our sonological findings and it was determined that the third vessel originating from the CCA was an aberrant superior thyroid artery (STA). Knowledge of variant terminations of the CCA is important to prevent inadvertent vascular injury during radical neck dissection, cervical discectomy, and carotid artery catheterization and a CDU is a prudent screening tool for the same.

Background To reduce the global burden of tobacco use, clinical guidelines support behavioral therapy and pharmacotherapy as preferred interventions for tobacco cessation. The evidence-based behavioral interventions has consistently shown to be impactful in community settings; however, its efficacy has not been established in hospital settings. The current study aims to investigate impact of trans-theoretical-based behavioral intervention package on tobacco users suffering from non-communicable diseases attending tertiary care settings of North India. Methods/design A two-arm randomized controlled trial (RCT) in a tertiary healthcare hospital will be performed. A total of 360 tobacco users attending NCD clinics in four departments, cardiology, neurology, pulmonary medicine, and ENT (otolaryngology), will be recruited over a period of 3 months. After ascertaining the eligibility criteria, they will be followed up to 6 months (1, 3, 6) for their tobacco use status, readiness to quit, nicotine dependence, stage of behavior change, and self-reported and biochemical validation (urine cotinine) for tobacco abstinence. Assignment of intervention including allocation concealment, sequence generation, and blinding will be done as per SPIRIT guidelines for RCT protocols. Discussion As no strong evidence exists about the effectiveness of tobacco cessation intervention in tertiary settings, the current study will build evidence about the similar interventions in such settings. Trial registration CTRI/2019/09/021406.

The Ischemic Stroke System is a novel device designed to deliver stimulation to the sphenopalatine ganglion(SPG).The SPG sends parasympathetic innervations to the anterior cerebral circulation. In rat stroke models, SPG stimulation results in increased cerebral blood flow, reduced infarct volume, protects the blood brain barrier, and improved neurological outcome. We present here the results of a prospective, multinational, single-arm, feasibility study designed to assess the safety, tolerability, and potential benefit of SPG stimulation inpatients with acute ischemic stroke(AIS). Patients with anterior AIS, baseline NIHSS 7-20 and ability to initiate treatment within 24h from stroke onset, were implanted and treated with the SPG stimulation. Patients were followed up for 90 days. Effect was assessed by comparing the patient outcome to a matched population from the NINDS rt-PA trial placebo patients. Ninety-eight patients were enrolled (mean age 57years, mean baseline NIHSS 12 and mean treatment time from stroke onset 19h). The observed mortality rate(12.2%), serious adverse events (SAE)incidence(23.5%) and nature of SAE were within the expected range for the population. The modified intention to treat cohort consisted of 84 patients who were compared to matched patients from the NINDS placebo arm. Patients treated with SPG stimulation had an average mRS lower by 0.76 than the historical controls(CMH test p = 0.001). The implantation procedure and the SPG stimulation, initiated within 24hr from stroke onset, are feasible, safe, and tolerable. The results call for a follow-up randomized trial (funded by BrainsGate; clinicaltrials.gov number, NCT03733236).

Background: Rehabilitation is probably one of the most important phases of recovery for many stroke survivors. The current study was conducted with the objective to assess the utilization of rehabilitation services and factors affecting nonutilization of rehabilitation services among the stroke survivors. Materials and Methods: The current study was carried out in the Neuro Outpatient Department of a tertiary care hospital in India. It was a descriptive study. Consecutive 55 stroke survivors who had met the inclusion and exclusion criteria were recruited in this study. Self-structured rehabilitation tool was used to collect the data. Results: Data were analyzed using the descriptive and inferential statistics. Majority of the patients comprised 70.9% of males and 29.1% of females. Among participants, 70.90% were aware about rehabilitation, 67% were utilizing rehabilitation services, whereas 33% were not utilizing rehabilitation services. In the current study, certain reasons were found behind not utilizing rehabilitation services. There were 83.3% of participants who had lack of awareness about rehabilitation services and 61.1% of participants who had no availability of rehabilitation services. Only 45.5% of rural inhabitants were utilizing rehabilitation services as compared to 81.2% of urban inhabitants and 83.23% of suburban inhabitants. Conclusion: Rehabilitation is of utmost importance. Hemiparesis, difficulty in performing activity of daily living, difficulty in performing social activities, and difficulty in reasoning were the most common problems faced by people suffering stroke after discharge from the hospital. There was lack of awareness and utilization of rehabilitation services by patients among Indian stroke population. Hence, health workers have an immense role in educating, motivating, and ensuring that rehabilitation services in rural inhabitants.

Background Cytochrome P450 system is implicated in vascular pathologies, including stroke. Besides its role as a drug metabolizer, it also plays an important role in the metabolism of several endogenous substances like fatty acids, arachidonic acid, etc., which have pro-inflammatory effects. On the other hand, leptin and adiponectin are two of the most common adipose tissue-derived cytokines (adipokines), which are pro-inflammatory and anti-inflammatory in nature, respectively. Both of them are implicated in the pathogenesis of stroke. Methods We prospectively recruited ischemic stroke patients (within three months of occurrence of an attack of stroke). The occurrence of composite outcome (recurrence of transient ischemic attack/ischemic stroke or death) was evaluated for association with genetic variants of CYP2C19 (allele *2, *17, *3, and *4, i.e., single nucleotide polymorphism (SNP) 1/2/3/4, identified using TaqMan assays and DNA sequencing). Adiponectin and leptin levels were determined using an enzyme-linked immunosorbent assay. Comparisons were made between stroke vs. control patients and between CYP2C19 intermediate metabolizer (IM)/poor metabolizer (PM) vs. extensive metabolizer (EM)/ultra metabolizer (UM) (PM: *2/*2; IM: *1/*2 vs. EM: *1/*1; UM: *1/*17). P < 0.05 was taken as the threshold for statistical significance. Results A total of 204 patients and 101 controls were recruited. With regard to the occurrence of stroke, SNP2 showed a significant positive association. Haplotypes (SNP1/SNP2) AC (OR = 1.75 (1.08-2.83), p = 0.024) and GT (OR = 3.33 (1.53-7.22), p = 0.0026) were strongly associated with the occurrence of ischemic stroke even after adjustment for age and sex (global haplotype association p-value: 0.0062). Haplotype phenotype gender interaction was evident. Among stroke patients, with regard to composite outcome, only SNP1 showed a positive association. The AC haplotype was significantly associated with the occurrence of composite outcome (OR = 2.27 (1.17-4.41), p = 0.016). Among stroke patients, a significant positive association was seen between death and SNP1 (OR = 2.35 (1.13-4.90), p = 0.021) and AC haplotype (OR = 2.73 (1.20-6.22), p = 0.018). However, none of the SNPs or haplotypes showed any association with recurrence. Significant higher leptin and lower adiponectin levels were observed among stroke patients compared to controls. Leptin levels were higher in IM/PM group. IM/PM phenotypes showed a higher incidence of occurrence of composite outcome (hazard ratio = 2.07 (0.96-4.47), p = 0.056). Conclusion CYP2C19 polymorphisms may play a significant role in the pathogenesis of stroke. Leptin could serve as a prominent biomarker of atherosclerosis and inflammation in the early post-stroke period; however, further study is warranted with a larger sample size.

Acute organophosphate (OP) poisoning is one of the most common poisonings in emergency medicine and toxicological practice in some of the less-developed nations in South Asia. Traditionally, OP poisoning comes under the domain of emergency physicians, internists, intensivists, and toxicologists. However, some of the complications following OP poisoning are neurological and involve neurologists. The pathophysiological basis for the clinical manifestations of OP poisoning is inactivation of the enzyme, acetylcholinesterase at the peripheral nicotinic and muscarinic and central nervous system (CNS) nerve terminals and junctions. Nicotinic manifestations occur in severe cases and late in the course; these comprise of fasciculations and neuromuscular paralysis. There is a good correlation between the electrophysiological abnormalities and the severity of the clinical manifestations. Neurophysiological abnormalities characteristic of nicotinic junctions (mainly neuromuscular junction) dysfunction include: (1) single, supramaximal electrical-stimulus-induced repetitive response/s, (2) decrement-increment response to high frequency (30 Hz) repetitive nerve stimulation (RNS), and (3) decremental response to high frequency (30 Hz) RNS. Atropine ameliorates muscarinic manifestations. Therapeutic agents that can ameliorate nicotinic manifestations, mainly neuromuscular, are oximes. However, the evidence for this effect is inconclusive. This may be due to the fact that there are several factors that determine the therapeutic effect of oximes. These factors include: The OP compound responsible for poisoning, duration of poisoning, severity of poisoning, and route of exposure. There is also a need to study the effect of oximes on the neurophysiological abnormalities.

The ongoing pandemic of COVID-19 is a global public health emergency. This has led to challenges for healthcare facilities to optimally manage other important medical emergencies. Stroke is an important public health emergency with significant mortality and morbidity. Timely treatment of acute stroke is critical to prevent disability. The current expert consensus statement on behalf of the Indian Stroke Association outlines the issues and suggestions related to the management of stroke during this ongoing COVID-19 pandemic.

Knowledge related to SARS-CoV-2 or 2019 novel coronavirus (2019-nCoV) is still emerging and rapidly evolving. We know little about the effects of this novel coronavirus on various body systems and its behaviour among patients with underlying neurological conditions, especially those on immunomodulatory medications. The aim of the present consensus expert opinion document is to appraise the potential concerns when managing our patients with underlying CNS autoimmune demyelinating disorders during the current COVID-19 pandemic.

Ulcerative colitis (UC) may have diverse extraintestinal manifestations. Nutritional deficiencies, medications or immune-mediated epiphenomena are considered to be pathogenic mechanisms involved. We describe a case of a 56-year-old woman who presented with rapidly progressive tingling paraesthesias in both lower limbs followed by sensory ataxia, ascending spastic quadriparesis, urgency and urge incontinence of 3 months duration. She had an episode of bloody diarrhoea 1 month later for which a colonoscopy was carried out with colonic biopsy features revealing a diagnosis of UC. In view of lack of alternative aetiology, the posterolateral column disease in our patient was attributed to an extraintestinal manifestation of UC. She improved dramatically with a course of intravenous steroids followed by tapering dose of oral steroids and oral mesalamine for her UC. Although rare, UC should be considered in the differential diagnosis of posterolateral column disease of the spinal cord in the appropriate clinical scenario.
