Percutaneous Device Closure of Congenital Isolated Ventricular Septal Defects:A Single-Center Retrospective Database Study Amongst 412 Cases

To identify suitable cases and reduce failure/complication rates for percutaneous ventricular septal defect (VSD) closure, we aimed to (1) study causes of device failure and (2) compare outcomes with different VSD types and devices in a high-volume single center with limited resources. Retrospective data of 412 elective percutaneous VSD closure of isolated congenital VSDs between 2003 and 2017 were analyzed. Out of 412, 363 were successfully implanted, in 30 device implantation failed, and in 19 the procedure was abandoned. Outcome was assessed using echocardiography, electrocardiography, and catheterization data (before procedure, immediately after and during follow-up). Logistic regression analyses were performed to assess effects of age, VSD type, and device type and size on procedural outcome. Median [interquartile range] age and body surface area were 6.6 [4.1-10.9] years and 0.7 [0.5-1.0] m(2), respectively. Device failure was not associated with age (p = 0.08), type of VSD (p = 0.5), device type (p = 0.2), or device size (p = 0.1). Device failure occurred in 7.6% of patients. As device type is not related to failure rate and device failure and complication risk was not associated with age, it is justifiable to use financially beneficial ductal devices in VSD position and to consider closure of VSD with device in clinically indicated children

To Study of Artemisia nilagirica Leaves for their Antithyroid, Oxidative and Antihyperglycemic Properties

The tiny, fragrant shrub Artemisia nilagirica (Clarke) is a member of the Asteraceae family. This plant's leaves and flowering top have been used in traditional medicine as an antimalarial, nerve tonic, and anticancer drug, and there is evidence of anti-leishmanial efficacy. Material and Methods: The plant specimen was obtained from the Ooty district in Tamil Nadu, India, during the month of December. It was subsequently authenticated by NMKRV College for Women, Bengaluru, Karnataka, India. The plant specimens were stored in the herbarium of the NMKRV College for Women, Bengaluru, Karnataka, India. Results: The morphological, microscopic, organoleptic, and other WHO-recommended procedures for standardization were investigated in a powdered sample of Artemisia nilagirica (Clarke) leaf. Phytochemical investigation revealed the existence of numerous elements such as alkaloids, amino acids, carbohydrates, flavonoids, glycosides, terpenoids, steroids, saponins, essential oils, tannins and phenol in diverse extracts. Conclusion: Pharmacognostic and phytochemical analysis of Artemisia nilagirica (Clarke) leaves would be useful for authenticating raw material or crude medication

Mini Forest - An experiment to evaluate the adaptability of Western Ghats species for afforestation

Saplings of forty nine species of trees from Western Ghats forests were planted on a 1.5 hectare tract of Deccan plateau (in the campus of Indian Institute of Science, Bangalore) and their performance monitored for 23 years. The objective was to evaluate their adaptability to a habitat and conditions apparently alien to these species. The study was also meant to understand the linkages of these trees with the surrounding environment. Contrary to the belief that tree species are very sensitive to change of location and conditions, the introduced trees have grown as good as they would do in their native habitat and maintained their phenology. Further, they have grown in perfect harmony with trees native to the location. The results show that the introduced species are opportunistic and readily acclimatized and grew well overcoming the need for the edaphic and other factors that are believed to be responsible for their endemicity. Besides ex situ conservation, the creation of miniforest has other accrued ecosystem benefits. For instance, the ground water level has risen and the ambient temperature has come down by two degrees

Incidental Chiari 1 malformation - yet another intra-operative cause for bradycardia: a case report: Incidental Chiari 1 malformation and intra-operative bradycardia

Chiari 1 malformation is characterized by descent of cerebellar tonsils through the foramen magnum. Most patients are asymptomatic or may present with non specific symptoms. We present a case of a 13 year old incidentally detected to have Chiari 1 malformation and developed significant bradycardia in the intra-operative perio

Update on pathology of ocular parasitic disease

Parasites are a group of eukaryotic organisms that may be free-living or form a symbiotic or parasitic relationship with the hosts. Consisting of over 800,000 recognized species, parasites may be unicellular (Protozoa) or multicellular (helminths and arthropods). The association of parasites with human population started long before the emergence of civilization. Parasitic zoonotic diseases are prevalent worldwide including India. Appropriate epidemiological data are lacking on existing zoonotic parasitic diseases, and newer diseases are emerging in our scenario. Systemic diseases such as cysticercosis, paragonimiasis, hydatidosis, and toxoplasmosis are fairly common. Acquired Toxoplasma infections are rising in immune-deficient individuals. Amongst the ocular parasitic diseases, various protozoas such as Cystoidea, trematodes, tissue flagellates, sporozoas etc. affect humans in general and eyes in particular, in different parts of the world. These zoonoses seem to be a real health related problem globally. Recent intensification of research throughout the world has led to specialization in biological fields, creating a conducive situation for researchers interested in this subject. The basics of parasitology lie in morphology, pathology, and with recent updates in molecular parasitology, the scope has extended further. The current review is to address the recent update in ophthalmic parasites with special reference to pathology and give a glimpse of further research in this field
