Hyaluronic acid covers in burn treatment: a systematic review

Abstract OBJECTIVE To evaluate the effectiveness of hyaluronic acid in the healing of partial thickness burns. METHOD Systematic review of randomized controlled trials on the use of hyaluronic acid for the topical treatment of skin burns, based on recommendations of the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS Two randomized controlled trials that analyzed 143 patients with partial thickness burns and/or deep partial thickness burns were selected. They compared the application of hyaluronic acid 0.2% associated to silver sulfadiazine 1% 5g/cm2 versus silver sulfadiazine 1% 5g/cm2 alone for the outcome of complete healing. CONCLUSION This review emphasizes the need for new well-designed randomized controlled trials to establish the therapeutic relevance of hyaluronic acid with respect to the healing of burns of partial thickness or deep partial thickness

A Framework for Healthcare Provision to Children with Intellectual Disability

Purpose: The Kudumbashree mission, an initiative of the Government of Kerala state in India, has collaborated with Local Self Governments to set up ‘Buds’, a special school system for individuals with intellectual disability. The objectives of this study were to evaluate the structure and functioning of ‘Buds’ schools, to identify the healthcare needs of the students, and to conceptualise a framework for healthcare provision. Methods: A cross-sectional survey was conducted among 202 children at 11 registered ‘Buds’ schools in Kerala. A multidisciplinary team consisting of a psychiatrist, public health personnel and a social worker from the Medical Colleges of Kerala, visited the institutions. Data collection consisted of abstraction from medical records, interviews with parents, and clinical assessment and prescription of intervention by the specialists concerned. A pre-tested semi-structured questionnaire was used for every child. Using both quantitative and qualitative techniques, the public health personnel in the team evaluated the structure and functioning of the schools. Results: The most commonly associated condition was epilepsy, seen in 11.9% of the children, while 28.2% had behavioural problems. The medicines needed were mainly anti-epileptics and drugs for behavioural problems. Interventions for self help and social skill training were also among the important requirements. The infrastructure and other facilities were poor in many schools, with the average student to teacher ratio at 14:1. While these institutions were well utilised, functioning was good only in 27.2% of the schools. Healthcare services and visits by healthcare personnel were far from adequate.  This study proposes a framework in which the Medical Colleges and Health Services can function together to deliver healthcare services to children at these schools, with linkages from the District Mental Health Programme (DMHP). Conclusion and Recommendation: Evidence that these schools are well utilised indicates a need to propagate this initiative in other areas of the state, country and other countries. However, improvements in infrastructure, human resources and other logistics are required. Besides, the healthcare needs of these children have to be addressed. A comprehensive healthcare programme through the existing system, using a multidisciplinary approach, needs to be developed.</p

Protein extraction and Western blotting from Methacarn-fixed tissue

Polyacrylamide gel electrophoresis (PAGE) of proteins with subsequent western blotting has become a routine technique for the analysis of proteins from both cultured cells and fresh whole tissue. We have developed a method to extract proteins from methacarn-fixed tissue which renders them suitable for SDS-PAGE and western blotting. With a panel of antibodies to specific intermediate filaments, transforming growth factor-α (TGF-α), and albumin, immunohistochemistry was performed in parallel with western blotting on sections cut from methacarn-fixed samples of normal rat liver and liver from rats treated under a regime which induces oval cell proliferation. Immunohistochemistry enabled the determination of changes in tissue distribution and abundance of the target proteins, which was mirrored by the corresponding western blot data. This technique can be especially effective when used in conjunction with immunohistochemistry. Tissue samples are easy to prepare, avoiding the precautions which need to be taken when handling fresh tissu
