Background: Antiplatelet therapy (APT) is an integral part of secondary stroke prevention. Noncompliance to APT is an important factor in stroke recurrence. In this study, we have evaluated the reasons for noncompliance to APT. Objective: The aim of this study was to identify the various causes of nonadherence to APT in recurrent stroke patients. Material and Methods: The study was conducted in a tertiary care hospital in south India with a huge stroke burden. The study period was from October 2017 to September 2018. A total of 60 consecutive patients of recurrent stroke who were nonadherent to antiplatelet therapy were evaluated for various factors that prevented compliance. Results: During the 12-month study period among 604 ischemic stroke patients, 128 (21%) had recurrent strokes. Of this 128, 60 (46.8%) were due to discontinuation of APT. The main factor for nonadherence to APT was lack of awareness about the need for lifelong medication (41/60; 68.3%). 10 patients (16.7%) stopped treatment as they opted for alternative therapy and 4 (6.7%) discontinued antiplatelets due to side effects. A small proportion of the patients (3.3%) cited financial constraints and forgetfulness as the issue, while 1.7% had difficulty in finding assistance to administer medicine. 27 (45%) patients had recurrent stroke within 2-15 days of stopping APT. Conclusions: The main reason for nonadherence to antiplatelet therapy is lack of awareness about the need for lifelong antiplatelet therapy. Stroke patients should be educated about the importance of lifelong antiplatelet therapy to prevent recurrent strokes.

Moya Moya disease is an important cause for childhood strokes and morbidity. An early diagnosis and treatment can prevent strokes and disability. Here we report the case of an eight-year-old boy who had transient episodes of headache and hemiparesis secondary to Moya Moya disease. He was misdiagnosed as hemiplegic migraine, seizure disorder, paroxysmal non-kinesigenic dyskinesia and dissociative disorder during the past three years. The diagnosis was significantly delayed as an important clinical cue was overlooked. A detailed history showed that symptoms were precipitated on eating spicy food. This clinical pointer prompted evaluation for Moya Moya disease. MRI and MR angiogram confirmed Moya Moya disease.

Objectives: The prevalence and characteristics of COVID-19-related headaches are not known in Indian patients. We aim to determine the prevalence and characteristics of headache in COVID-19-infected individuals and make a comparison with those without headaches. Methods: This prospective cross-sectional observational study was conducted from 1 October to 31 October 2020. Data were collected using a detailed questionnaire. We compared the data of those with and without headaches to identify the differences between the groups. Results: During the study period of 1 month, among 225 COVID-19-infected patients, 33.8% patients had headaches. The mean age of patients with headache was 48.89 ± 15.19 years. In all, 53.9% were females. In 65.8%, headache occurred at the onset of viral illness; 44.7% described the headache as dull aching; 39.5% had bifrontal headache; and 32.9% had holocranial headache. In total, 78.9% had complete resolution of headache within 5 days. A comparison between those with and without headaches showed that those with headaches were more younger (48.89 ± 15.19 vs 54.61 ± 14.57 years, p = 0.007) and of female gender (41/76(53.9%) vs 41/149 (27.5%), p = 0.001). Primary headache disorders were more common in the headache group. Levels of inflammatory markers such as leukocyte count (7234.17 ± 3054.96 vs 8773.35 ± 5103.65, p = 0.017), erythrocyte sedimentation rate (39.28 ± 23.29 vs 50.41 ± 27.61, p = 0.02) and ferritin (381.06 ± 485.2 vs 657.10 ± 863.80, p = 0.014) were lower in those with headaches. Conclusions: Headaches are a common and early symptom of acute SARS-CoV-2 infection more frequently seen in young females and in those with a history of primary headache disorders. The lower level of inflammatory markers in those with headaches suggests that these headaches are probably due to the local spread of virus through the trigeminal nerve endings, resulting in activation of the trigeminovascular system.

Background: Rituximab is reserved for treating refractory myasthenia gravis (MG) patients. Here we report our experience with rituximab in AChR antibody positive generalized MG (gMG) and impending myasthenic crisis (IMC). Methods: This retrospective, observational study, conducted at a tertiary care, neuroimmunology clinic, analyzed the data of patients with AChR antibody positive gMG, treated with rituximab between 1st January 2016 and 30th October 2018. Results: Eleven patients with AChR antibody positive gMG received rituximab. Mean age of the cohort was 50.54 ± 18.71 years with 9 males. Seven out of 11 patients received rituximab in the early stage (<2 years from onset) and had good response to treatment. Four of the 5 patients with IMC improved with rituximab alone. In the 10 patients who regularly followed up, there was a significant difference between the QMG scores at baseline and at 1, 2, 6, 12, and 18 months (P < .0001). Conclusion: Rituximab appears to be a potentially effective early treatment option for AChR antibody positive generalized MG and impending myasthenic crisis.

Pontocerebellar hypoplasia type 6 (PCH6) is an autosomal recessive mitochondrial disease, typically characterized by pontine atrophy, vermian hypoplasia, infantile encephalopathy, generalized hypotonia, and intractable seizures. The purpose of this study is to describe the seizures and other neurological manifestations of RARS2 gene mutations and to compare the clinical features with other causes of progressive myoclonic epilepsy. Detailed history, physical examination, and clinical and genetic work-up were performed in 2 siblings who presented with progressive myoclonic epilepsy. One sibling, a 20-year-old woman, and the other a 24-year-old man, had a homozygous missense variant (c.848T>A; p.Leu283Gln) in exon 10 of the RARS2 gene. The female patient had action and audiogenic myoclonic jerks, postural tremors, spastic dysarthria, and bradykinesia, and her male sibling had similar features with oculomotor apraxia. The RARS2 gene mutation can present with myoclonic epilepsy, mental retardation, and pyramidal and extrapyramidal features, and is an important differential for causes of progressive myoclonic epilepsy.Pontocerebellar hypoplasia type 6 (PCH6) is an autosomal recessive mitochondrial disease, typically characterized by pontine atrophy, vermian hypoplasia, infantile encephalopathy, generalized hypotonia, and intractable seizures.

The objective of this review was to examine the current use of remotely piloted aircraft (RPA) in obtaining data to assist in the application of precision farming techniques and to exemplify successful situations of technology use. The RPA has applications for monitoring, mapping, vegetation index (VI) extraction, volume, plant height, among others, and has been studied in several agricultural crops, being support for decision making on agrochemical application, planting failure, accompaniment of growth favoring the increase of crop productivity. One of the potentialities evaluated through RPA is the use of VI, which may be extracted from digital images obtained by cameras that contain only the visible band. It may be an alternative for farmers who do not have access to RPA coupled with high-tech embedded sensors. Therefore, it is a tool that may contribute to the decision making, allowing the acquisition of high spatial and temporal resolution images.
