    Microsponge refers to a highly cross-linked particle system with a capacity to adsorb (like a dry sponge) pharmaceutical materials. There are various methods available to prepare microsponge formulations, in this study we used quasi emulsion-solvent diffusion method with a combination of hydrophobic (ethyl cellulose) and hydrophilic polymers (hydroxypropyl methylcellulose) mediated via Tween 80 and polyvinyl alcohol. Various ratios and amounts of the polymers and surfactants were used to prepare microsponge formulations using ketoprofen as a model drug and extensively characterised. Our results, for the first time, indicate successful and optimised formulation with desired pharmaceutical characteristics using a combination of hydrophobic and hydrophilic polymers

    Introduction: CNS tumors are the most common solid tumors in children. Tumors of the central nervous system can be divided into primary intracranial tumours that arise from parenchyma of brain, pituitary gland, covering of brain & secondary intracranial tumours which represent local extension from regional tumours or metastasis from primary malignancy in the body. The most common location of the brain tumours in childhood is below the tentorium within the posterior cranial fossa. Materials and methods: Surgical specimen of central nervous system of children (0 to 14 year of age group) received from August 2013 to November 2015, in the Tertiary care center, Ahmedabad were studied with keeping the following features in mind: Age, Sex and site of tumours. Results: Fifty eight cases of central Nervous system Tumours between the age of 0 to 14 years over a period of 2.5 years at civil hospital, Ahmedabad were studied. Incidence were more common in male (60.34%) than female(39.66%) 89.65% were intracranial to 10.35% were intraspinal tumours.Commonly encountered tumour in descending order of frequency were Medulloblastoma (27.58%), astrocytoma (24.13%), Ependymoma (20.68%). All medulloblastomas arose infratentorial, schwannomas arose intraspinal and meningiomas in cranial cavity are supratentorial. Conclusion: CNS Tumors constitute a large proportion of cancers in childhood. They differ from adult CNS tumors both histologically and location wise. Site of the tumor is significant as it can lead to fatal consequence

    Purpose: The aim of study was to assess the prevalence of osteoporosis and changes in bone mass with increasing age and compare bone health status of apparently healthy men, premenopausal and postmenopausal women. Methods: Data were collected on anthropometric and sociodemographic factors in 421 apparently healthy Indian adults (women = 228), 40–75 years of age, in a cross-sectional study in Pune city, India. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry at two sites-lumbar spine (LS) and left femur. Individuals were classified as having osteoporosis or osteopenia based on the World Health Organization criteria of T-scores. Results: Mean age of study population was 53.3 ± 8.4 years. Of the total women, 44.3% were postmenopausal with 49.2 ± 3.5 years as mean age at menopause. Postmenopausal women showed a rapid decline in BMD with age till 50 years while men showed a gradual decline. Premenopausal women showed no significant decline in BMD with age (P > 0.1). Significantly lower T-scores were observed at LS in men compared to premenopausal (P 0.1). The prevalence of osteoporosis in men at LS was lower than postmenopausal women but higher than premenopausal women. Conclusion: In Indian men, a low T-score compared to women indicates higher susceptibility to osteoporosis. In women, menopause causes a rapid decline in BMD. Therefore, both Indian men and postmenopausal women require adequate measures to prevent osteoporosis during later years in life

    BACKGROUND:Government of India is committed to eliminate measles and control rubella/congenital rubella syndrome (CRS) by 2020. In 2016, CRS surveillance was established in five sentinel sites. We analyzed surveillance data to describe the epidemiology of CRS in India. METHODOLOGY/PRINCIPAL FINDINGS:We used case definitions adapted from the WHO-recommended standards for CRS surveillance. Suspected patients underwent complete clinical examination including cardiovascular system, ophthalmic examination and assessment for hearing impairment. Sera were tested for presence of IgM and IgG antibodies against rubella. Of the 645 suspected CRS patients enrolled during two years, 137 (21.2%) were classified as laboratory confirmed CRS and 8 (1.2%) as congenital rubella infection. The median age of laboratory confirmed CRS infants was 3 months. Common clinical features among laboratory confirmed CRS patients included structural heart defects in 108 (78.8%), one or more eye signs (cataract, glaucoma, pigmentary retinopathy) in 82 (59.9%) and hearing impairment in 51. (38.6%) Thirty-three (24.1%) laboratory confirmed CRS patients died over a period of 2 years. Surveillance met the quality indicators in terms of adequacy of investigation, adequacy of sample collection for serological diagnosis as well as virological confirmation. CONCLUSIONS/SIGNIFICANCE:About one fifth suspected CRS patients were laboratory confirmed, indicating significance of rubella as a persistent public health problem in India. Continued surveillance will generate data to monitor the progress made by the rubella control program in the country
