Smart healthcare is an integral part of a smart city, which provides real time and intelligent remote monitoring and tracking services to patients and elderly persons. In the era of an extraordinary public health crisis due to the spread of the novel coronavirus (2019-nCoV), which caused the deaths of millions and affected a multitude of people worldwide in different ways, the role of smart healthcare has become indispensable. Any modern method that allows for speedy and efficient monitoring of COVID19-affected patients could be highly beneficial to medical staff.

Mutants with unique characters have played a key role in discovery of gene, mapping, functional genomics and breeding in many vegetable crops, but information on bitter gourd is lacking. Induction of mutation by gamma rays (Co source) at five different doses (50 Gy, 100 Gy, 150 Gy, 200 Gy and 250 Gy) was studied in four widely divergent bitter gourd genotypes BG-1346501, Meghna-2, Special Boulder and Selection-1 in M generation. Reduction in seed germination percentage, vine length and pollen fertility occurred in M1 generation with the increasing doses of mutagens.

Okra production in eastern India at present is severely threatened by whitefly-mediated okra enation leaf curl disease (OELCuD). Identification of resistant genotype and understanding the genetic control and biochemical relationship of OELCuD resistance are prerequisite for developing an effective breeding strategy. This study was conducted employing six populations (P, P, F, F, BC and BC) of two selected (resistant x susceptible (RxS)) crosses.

Development of mutants and their effective utilization to incorporate desirable traits in tomato would be a sound improvement strategy to develop so called 'smart' tomato variety of the coming century. Initially we developed three induced mutants from two varieties, 'Patharkuchi', a local adapted cultivar and an introduced variety 'Berika', and then three crosses (Berika 9 P Mut-5, Berika 9 P Mut-11, Patharkuchi 9 B Mut-1) were made to involve in these two varieties and their respective mutants. Six generations (P, P, F, F, BC and BC) of three crosses were utilized to study the genetic control of yield and quality traits, and to study the genetic basis of formation of dark green fruit.

Okra's (Abelmoschus esculentus (L.) Moench) commercial cultivation is threatened in the tropics due to high incidence of yellow vein mosaic virus (YVMV) disease. Okra geneticists across the world tried to understand the inheritance pattern of YVMV disease tolerance without much success.

Childhood disintegrative disorder (CDD) (ICD-10 F84.3) is defined by a period of normal development before onset followed by gradual loss of previously acquired skills with the development of characteristic abnormalities of social, communicative and behavioural functioning. We report two children with apparent CDD, who showed amelioration of behaviour, language and motor regression after corticosteroid treatment.

Ataxia and peripheral neuropathy are the most common neurological manifestations of gluten sensitivity. Myopathy is a less common and poorly characterized additional neurological manifestation of gluten sensitivity. We present our experience with 13 patients who presented with symptoms and signs suggestive of a myopathy and in whom investigation led to the diagnosis of gluten sensitivity.

We studied the effect of a gluten-free diet in patients with idiopathic sensorimotor axonal neuropathy and circulating antigliadin antibodies. Consecutive patients underwent baseline neurophysiological assessment and were offered a gluten-free diet. Those who went on the diet formed the intention-to-treat group and those who did not were the control group.

We describe a patient who entered a stuporous state after receiving benzodiazepine treatment for generalized tonic-clonic status epilepticus. A diagnosis of generalized NCSE with tonic seizures was made on the basis of the clinical picture and response to barbiturate anaesthetic, although the EEG pattern was not typical of the changes previously described in tonic seizures-tonic status epilepticus. This report discusses the differential diagnosis of postictal stupor, nonconvulsive status epilepticus with tonic seizures and sedation caused by the emergency treatment of status epilepticus, and summarizes the literature on tonic seizures and tonic status epilepticus.
