Adverse drug effects monitoring of amlodipine in a tertiary care hospital

Background: Amlodipine have been widely used drug for the treatment of Hypertension. It has many beneficial effects and less side effects. But, only very few adverse effects of Amlodipine have been documented and many were not reported. So, this study will bring out the possible adverse effect of Amlodipine.Methods: This study included 100 patients with hypertension who are taking amlodipine only. Patients who were willing to participate in the study were given a questionnaire containing demographic data and adverse drug profile of amlodipine. The symptoms of adverse drug reaction were documented. They were also asked about the other symptoms they are having, other than the questionnaire. The causality assessment was done by WHO assessment scale and severity by using modified Hartwig seigel severity assessment scale.Results: This study showed that most of the patients belong to 51-60 years age group. Mostly they were females, and many were having disease for less than a year. Most of the patients developed adverse drug reaction. Many patients had more than one adverse drug reaction. The commonest adverse effect were fatigue, palpitation, dizziness, insomnia, headache, joint pain, light-headedness, somnolence, nausea, flushing abdominal pain, tremor, leg pain, neck pain, back pain and edema. The adverse drug reaction(ADRs) mostly belongs to possible category and were mild.Conclusions: Most of the patients who were taking amlodipine had atleast one adverse drug reaction during their treatment period. It is mild, needs dose adjustment and healthy life style modification

Comparative study of adverse drug reaction pattern of two anti-asthma groups of drugs in a tertiary care hospital

Background: Bronchial Asthma is one of the worldwide health problems associated with increased morbidity and also mortality. Bronchial Asthma is a disease of airways that is characterized by increased responsiveness of the trachea-bronchial tree. Anti asthmatic drugs are associated with adverse effects which can affect the compliance and course of treatment. Monitoring adverse drug reactions in asthma will play a vital role in alerting physicians about the possibility and circumstances of such events, thereby protecting the user population from avoidable harm.Methods: The study was conducted in 500 bronchial asthma patients (250 patients in Beta 2 agonist group (Salbutamol) and 250 patients in Methylxanthine group (Deriphyllin) who fulfilled the study criteria and were observed for three months at Madras Medical College and Rajiv Gandhi Government General Hospital, Chennai. Their prescriptions were collected and analysed. Adverse drug reactions(ADRs) in each group were collected and evaluated. The causality assessment was done by WHO-UMC assessment scale and severity by using Modified Hartwig-Seigel severity assessment scale.Results: Total 38% of patients taking anti-asthma drugs were encountered adverse drug reactions and were more common in elderly females (61 to 70 years). Adverse Drug Reactions were more common in Methylxanthine group (48%) compared to Beta 2 agonist group (28%). Headache (38%) was the commonest ADR in Methylxanthine group and Tremors (31%) in Beta 2 agonist group. Most of ADRs were mild (95 %), manageable and comes under possible (60 %) category of WHO causality assessment scale.Conclusions: Treatment of Bronchial Asthma is mainly based on Beta 2 agonist and Methylxanthine group. So, occurrence of ADR is much common. Our study offers a representative idea of the ADR profile of anti asthmatic drugs. Constant vigil in detecting ADRs and subsequent dose adjustments can make therapy with anti asthmatic drugs safer and more effective. This, in turn, will improve compliance

Clinical prevalence of stroke in a tertiary care hospital in Southern India

Background: Stroke is the second most deadly disease in the world next only to ischemic heart disease. The incidence of stroke continues to rise particularly among young individuals. Given the paucity of data and lack of reliable reporting mechanisms, understanding the epidemiology of stroke in India is challenging. This study aims to review the prevalence of stroke in a tertiary care hospital in southern India.Methods: The study includes all the Stroke patients admitted in Government Rajaji Hospital and Madurai Medical College, Madurai during the period of 01 January 2018 to 31 December 2018.Results: A total of 1168 patients were taken into study, there were 779 males and 389 females. There were a total of 848 ischaemic stroke patients (72.60%), when compared to 320 haemorrhagic stroke patients 27.39%. Anterior circulation stroke prevalence was higher (88.27%) when compared to posterior circulation stroke. A total 498 patients (42.63%) belonged to the age group of 40 to 60 years.Conclusions: There is inadequate data regarding the prevalence of stroke in India and decade old data indicates that there is an increasing prevalence. Hence the study reviewed the current prevalence of stroke in a tertiary care centre in southern Tamil Nadu

Implementation of Driver Software of Trailer Module Chip

The aim of the project is to develop a driver software for UJA1076A SBC in embedded C using IAR Embedded Workbench and integrate the driver software with application software of Trailer module. Currently MC33903 system basis chip from Freescale is used in Trailer Module. As an initiative to reduce the material cost for the Trailer module product, a lower price SBC NXP UJA1076A has been used. Also due to the fact that the newly proposed SBC has less number of operating modes and registers to configure, it helps in making the driver software much more simpler, thus reducing the risk of hidden issues in the otherwise complex design and code of the current SBC driver software

The cell adhesion molecule Tag1, transmembrane protein Stbm/Vangl2, and Lamininα1 exhibit genetic interactions during migration of facial branchiomotor neurons in zebrafish

AbstractInteractions between a neuron and its environment play a major role in neuronal migration. We show here that the cell adhesion molecule Transient Axonal Glycoprotein (Tag1) is necessary for the migration of the facial branchiomotor neurons (FBMNs) in the zebrafish hindbrain. In tag1 morphant embryos, FBMN migration is specifically blocked, with no effect on organization or patterning of other hindbrain neurons. Furthermore, using suboptimal morpholino doses and genetic mutants, we found that tag1, lamininα1 (lama1) and stbm, which encodes a transmembrane protein Vangl2, exhibit pairwise genetic interactions for FBMN migration. Using time-lapse analyses, we found that FBMNs are affected similarly in all three single morphant embryos, with an inability to extend protrusions in a specific direction, and resulting in the failure of caudal migration. These data suggest that tag1, lama1 and vangl2 participate in a common mechanism that integrates signaling between the FBMN and its environment to regulate migration
