Background: Vascular endothelial growth factor is well known for its angiogenesis potential. The study was performed to determine the possible pro-angiogenic role of magnetic nanoparticles coupled to VEGF in vitro and their capacity to cross an endothelial monolayer. This novel treatment technique for angiogenesis could be potentially useful for therapeutic purposes using magnetic nanoparticles. Methods: Magnetic nanoparticles (MN) were synthesized and were conjugated with the vascular endothelial growth factor. The particles were tested in vitro in a 2D to 3D culture system. MN was seeded in different positions in relation to an HUVEC spheroid to assess a preferential migration. To evaluate the MN capacity to cross the endothelial barrier, a confluent monolayer of HUVEC cells was seeded on top of a collagen gel. MN was placed in dissolution on the cell culture media, and the MN position was determined by confocal microscopy for 24 h. Results: HUVEC spheroids were able to generate a preferential sprouting depending on the MN position. Meanwhile, there was random migration when the MN's were placed all over the collagen gel and no sprouting when no MN was added. The trans-endothelial migration capacity of the MN was observed after 20 h in culture in the absence of external stimuli. Conclusion: Here we show in vitro angiogenesis following the distribution of the MN conjugated with growth factors. These nanoparticles could be controlled with a magnet to place them in the ischemic area of interest and speed up vascular recovery. Also, MN has potentials to cross endothelium, opening the doors to a possible intravascular and extravascular treatment. © 2017 The Author(s).

Introduction: To evaluate the hepatoprotective activity of active phytochemicals, picroliv, curcumin, and ellagic acid in comparison to silymarin in the mice model of carbon tetrachloride (CCl 4 ) induced liver toxicity. In addition, attempts were made to elucidate their possible mechanism(s) of action. Materials and Methods: Oxidative stress was induced in Swiss albino mice by a single injection (s.c.) of CCl 4 , 1 ml/kg body weight, diluted with arachis oil at a 1:1 ratio. The phytochemicals were administered once a day for 7& days (p.o.) aspretreatment at two dose levels (50and 100mg/kg/day). Results: CCl 4 -induced hepatotoxicity was manifested by an increase in the activities of liver enzymes (alanine transaminase, P < 0.001, aspartate transaminase, P < 0.001 and alkaline phosphatase, P < 0.001), malondialdehyde (MDA, P < 0.001)) levels and a decrease in activity of reduced glutathione (P < 0.001) and catalase in liver tissues. The histopathological examination of liver sections revealed centrizonal necrosis, fatty changes, and inflammatory reactions. The pretreatment with picroliv, curcumin, and ellagic acid normalized serum aminotransferase activities (P < 0.001), decreased levels of MDA (P < 0.001), improved the antioxidant status, and normalized the hepatic histo-architecture. The restoration of phenobarbitone-induced sleeping time also suggested the normalization of liver cytochrome P450enzymes. Conclusion: This study supports the use of these active phytochemicals against toxic liver injury, which may act by preventing lipid peroxidation, augmenting the antioxidant defense system or by regenerating the hepatocytes.

The National Board of Examinations conducts the Diplomate of the National Board in broad specialities as well as in core super specialities. The programme was meant to provide a common standard and a mechanism of evaluation the These programmes, as per the prospectus of the DNB course are meant to provide the basic level ofcompetence required for the postgraduate qualification in that subject. However, it has failed to meet these objectives. It is imperative to re-examine and revamp the system to improve its credibility and acceptability at both the national and international levels.

It is the obligation of the state to provide free and universal access to quality health-care services to its citizens. India continues to be among the countries of the world that have a high burden of diseases. The various health program and policies in the past have not been able to achieve the desired goals and objectives. 65 th World Health Assembly in Geneva identified universal health coverage (UHC) as the key imperative for all countries to consolidate the public health advances. Accordingly, Planning Commission of India constituted a high level expert group (HLEG) on UHC in October 2010. HLEG submitted its report in Nov 2011 to Planning Commission on UHC for India by 2022. The recommendations for the provision of UHC pertain to the critical areas such as health financing, health infrastructure, health services norms, skilled human resources, access to medicines and vaccines, management and institutional reforms, and community participation. India faces enormous challenges to achieve UHC by 2022 such as high disease prevalence, issues of gender equality, unregulated and fragmented health-care delivery system, non-availability of adequate skilled human resource, vast social determinants of health, inadequate finances, lack of inter-sectoral co-ordination and various political pull and push of different forces, and interests. These challenges can be met by a paradigm shift in health policies and programs in favor of vulnerable population groups, restructuring of public health cadres, reorientation of undergraduate medical education, more emphasis on public health research, and extensive education campaigns. There are still areas of concern in fulfilling the objectives of achieving UHC by 2022 regarding financing model for health-care delivery, entitlement package, cost of health-care interventions and declining state budgets. However, the Government′s commitment to provide adequate finances, recent bold social policy initiatives and enactments such as food security bill, enhanced participation by civil society in all health matters, major initiative by some states such as Tamil Nadu to improve health, water, and sanitation services are good enough reasons for hope that UHC can be achieved by 2022. However, in the absence of sustained financial support, strong political will and leadership, dedicated involvement of all stakeholders and community participation, attainment of UHC by 2022 will remain a Utopia.

Background: Pityriasis rosea is an acute self-limiting skin disorder of unknown aetiology. Recently human herpes virus 6 and 7 has been hypothesized to be the cause of pityriasis rosea. Objective: To determine the efficacy of acyclovir, an anti-viral drug, in the treatment of pityriasis rosea. Materials and Methods: A randomized, double-blind, placebo-controlled study of efficacy of oral acyclovir in the treatment of pityriasis rosea was conducted on 73 patients. Thirty eight randomly selected patients were started on oral acyclovir. Thirty-five patients were prescribed placebo. The patients as well as the chief investigator were unaware of the therapeutic group to which patients belonged (acyclovir or placebo). Patients in both the groups were evaluated clinically after 7 and 14 days following the first visit and the data were analysed. Results: Follow up data of 60 patients was available and these were included in the statistical analysis. 53.33% and 86.66% of the patients belonging to the acyclovir group showed complete resolution on the 7th day and 14th day respectively following the first visit compared to 10% and 33.33% of patients from the placebo group. The findings were statistically significant. Conclusion: The study showed that high dose acyclovir is effective in the treatment of pityriasis rosea.

Advances in medicine have increased the life expectancy resulting in an increase in the geriatric population all over the world, and their proportion will only continue to rise in the coming years. It is known that the elderly bear a significant burden of morbidity, which is why health systems globally spearheaded by the WHO are waking up to the need for better geriatric health services. This includes India, whose health system continues to grapple with the health challenges of communicable and noncommunicable diseases. This article enumerates the various government policies and programs, constitutional and legal provisions available for the care of the elderly, and concludes that they are grossly inadequate to deal with the various physical, psychological, and emotional needs of the aging population. Mainstreaming of geriatric health to address the health needs of the elderly at all levels of health care, both in the public and the private sectors, giving due importance to multidimensional rehabilitative services and terminal care, involving NGOs and voluntary organizations, and stepping up social security in old age are the recommended measures for improving geriatric health in India.

Benign enlargement of sub-arachnoid spaces (BESS) is one of the causes of macrocephaly in infants. It is a self-limiting condition and does not require any active medical or surgical treatment. We report a case of an infant aged 4 months who was referred for magnetic resonance imaging (MRI) of the brain as the head circumference of the infant had increased rapidly from the 50 th percentile in the 3 rd month to more than the 95 th percentile in the 4 th month of age. MRI revealed enlarged anterior sub-arachnoid spaces and mild prominence of all the ventricles. A possibility of BESS was suspected since the child was neurodevelopmentally normal. A follow-up MRI done at the age of 18 months showed a reduction in the size of the sub-arachnoid spaces with normal sized ventricles.

Pityriasis rosea is an acute self-limiting papulosquamous skin disorder of unknown etiology. Although pityriasis rosea is a common dermatologic disorder, information regarding the epidemiology of the disease in India is limited because of inadequate studies. The incidence and presentation of pityriasis rosea varies from one geographical region to another. The objective was to study the various clinical patterns of the disease and epidemiologic factors influencing its occurrence. A cross-sectional study on the clinicoepidemiologic pattern of pityriasis rosea was conducted. A detailed history of illness regarding onset, evolution, duration, symptoms, systemic features, recurrence, history of contact, and associated factors such as socioeconomic status, history of drug intake, and use of new clothing, along with epidemiologic data, was recorded in the performa. The age of the patients ranged from 3 to 47 (mean 20.32) years. Incidence of pityriasis rosea was highest among patients aged 11 to 20 years followed by those 21 to 30 years. There was a male preponderance. Seasonal variation was not evident. History of using new garments or old garments, unwashed for an extended period was elicited in 23% of cases. The average interval of onset of lesions and presentation to physician was 14.45 days. Pruritus was a common symptom (70%). Of 73 patients, 67 had herald patch. The clinical features of most of the cases were in accordance with the classical pattern of pityriasis rosea.

We studied the incidence and the risk factors predisposing to post transplantation urinary tract infection (UTI) and the association with use of different immunosuppressive regimens. We performed a retrospective analysis of 152 recipients of renal transplantation over a period of two years. Seventy one (46.71%) patients had culture positive UTI, Escherichia coli (45.1%) being the commonest. Thirty four (22.39%) patients had acute rejection and 14.4% of those had suffered UTI in the early post transplant period. Immunosuppression included induction with various antibodies and maintenance on antirejection medications. Trimethoprim-sulphamethoxazole was given as prophylaxis throughout the period. The UTI was treated according to microbiological sensitivity. 2.8% died due to urosepsis. In our retrospective analysis renal transplant recipients under the age of 45, female gender and diabetics suffered more UTI. Combination therapy with micro-emulsion form of cyclosporine A, prednisolone and azathioprine developed more UTI (P= 0.0418).
