Shoulder injuries are extremely common in sportspeople involved in overhead sports and even in casual sportspersons. With increasing interest in activities such as tennis, golf, squash, badminton not to mention cricket, many of our colleagues are seeing a lot of these individuals with disabling pains. Many unnecessary investigations are being done where most diagnosis can be made by good clinical examination and knowledge of pathology. Therapy plays a very important part in the rehabilitation of these injuries, although again certain protocols have to be followed. The review will look at some of the common pathologies and also treatment options and also some specific injuries related to few sports. © 2011 Delhi Orthopedic Association. Source

Aberrations in ubiquitin pathway have been implicated in many diseases and drug response. In a previous study on rheumatoid arthritis (RA) in Japanese population, significant association of Cullin1 gene (CUL1), an ubiquitin E3 ligase, was observed. CUL1 also mediates degradation of IκBα and p27, levels of which has been associated with RA etiology and drug response, respectively. We carried out a replication study of association of CUL1 polymorphisms with RA in a north Indian population. Allelic, genotypic, and haplotypic associations of a promoter and two intronic polymorphisms of CUL1 with RA and with methotrexate response in patients with RA, were tested. A significant association (P=0.00056, adjusted) of a haplotype A-T-T with RA (odds ratio=3.68; 95% confidence interval=1.86-7.27) and in patients with RA poorly responding to methotrexate treatment (P=0.04, adjusted) was observed. Association with CUL1 haplotype indicates a possible role of CUL1 variation(s) in RA and its response to methotrexate. © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins. Source

Expert Opinion on Biological Therapy | Year: 2010

Importance of the field: Ever since the formation of the first biotechnology company almost three decades ago, more than 150 biopharmaceutical products have been marketed across the globe. The oldest of these biotechnology-derived products are now at the end of their patent lives, as a result of which, the development of 'biosimilars' is increasing. Areas covered in the review: The review highlights aspects in which biosimilars differ from generic drugs. What the reader will gain: The active substance of a biosimilar medicine is similar to the one of the biological reference medicine; however, biosimilars differ from generics of pharmacological drugs in aspects like size and complexity of the active substance, and the nature of the manufacturing process. The manufacture of a biopharmaceutical product is complex and involves several isolation and purification steps. These procedures are proprietary to the manufacturer of the originator product and hence even minor changes in production can have serious implications in terms of safety and efficacy of the product. Take home message: Biosimilars should not be brought to market using the same procedure applied to generics, and existing and future regulation should prevent inappropriate and automatic substitution of a biosimilar for a reference biopharmaceutical product. © 2010 Informa UK Ltd.

Introduction: Implementation of the Surviving Sepsis Campaign (SSC) guidelines has been associated with improved outcome in patients with severe sepsis. Resolution of lactate elevations or lactate clearance has also been shown to be associated with outcome. The purpose of the present study was to examine the compliance and effectiveness of the SSC resuscitation bundle with the addition of lactate clearance.Methods: This was a prospective cohort study over 18 months in eight tertiary-care medical centers in Asia, enrolling adult patients meeting criteria for the SSC resuscitation bundle in the emergency department. Compliance and outcome results of a multi-disciplinary program to implement the Primary SSC Bundle with the addition of lactate clearance (Modified SSC Bundle) were examined. The implementation period was divided into quartiles, including baseline, education and four quality improvement phases.Results: A total of 556 patients were enrolled, with median (25th to 75th percentile) age 63 (50 to 74) years, lactate 4.1 (2.2 to 6.3) mmol/l, central venous pressure 10 (7 to 13) mmHg, mean arterial pressure (MAP) 70 (56 to 86) mmHg, and central venous oxygen saturation 77 (69 to 82)%. Completion of the Primary SSC Bundle over the six quartiles was 13.3, 26.9, 37.5, 45.9, 48.8, and 54.5%, respectively (P <0.01). The Modified SSC Bundle was completed in 10.2, 23.1, 31.7, 40.0, 42.5, and 43.6% patients, respectively (P <0.01). The ratio of the relative risk of death reduction for the Modified SSC Bundle compared with the Primary SSC Bundle was 1.94 (95% confidence interval = 1.45 to 39.1). Logistic regression modeling showed that the bundle items of fluid bolus given, achieve MAP >65 mmHg by 6 hours, and lactate clearance were independently associated with decreased mortality - having odds ratios (95% confidence intervals) 0.47 (0.23 to 0.96), 0.20 (0.07 to 0.55), and 0.32 (0.19 to 0.55), respectively.Conclusions: The addition of lactate clearance to the SSC resuscitation bundle is associated with improved mortality. In our study patient population with optimized baseline central venous pressure and central venous oxygen saturation, the bundle items of fluid bolus administration, achieving MAP >65 mmHg, and lactate clearance were independent predictors of outcome. © 2011 Nguyen et al.; licensee BioMed Central Ltd.

Best Practice and Research: Clinical Rheumatology | Year: 2014

Polyarthritis comprises a large number of conditions ranging from rheumatoid arthritis (RA) to metabolic conditions such as ochronosis. Differential diagnosis begins with delineation of inflammatory from non-inflammatory disorders using laboratory markers of inflammation. The latter are good but they can be misleading. Laboratory tests help in the diagnosis of rheumatic diseases as well as their prognostication. The choice of serological tests should be based on clinical differential diagnosis and not 'arthritis panels'. The point of time when the test is performed in the clinical course of disease can have an important influence on the result obtained. Anti-citrullinated protein antibody (ACPA), rheumatoid factor, human leucocyte antigen (HLA) B27 and imaging are routinely employed for the early diagnosis of RA and spondyloarthritis (SpA). Despite advances in musculoskeletal imaging modalities such as ultrasonography (USG) with power Doppler, conventional as well as extremity magnetic resonance imaging (MRI) and dual-energy computed tomography (DECT), their exact place in clinical rheumatology remains to be defined. Synovial fluid examination has only a limited role in the investigations of new-onset polyarthritis. © 2015 Elsevier Ltd. All rights reserved. Source
