    Get PDF
    Rhabdomyolysis is a syndrome characterized by muscle necrosis and the release of intracellular muscle constituents into the circulation. Here, we report the case of an 18-year-old male with cerebral palsy who was admitted to the hospital with symptoms of lower respiratory tract infection and with high-grade fever. His initial blood workup revealed an elevated creatinine and CPK of 32,000 which was suggestive of rhabdomyolysis. His worsening renal function with acidosis and hyperkalemia required initiation of hemodialysis. A respiratory viral PCR profile revealed Influenza B. He was re-started on Oseltamivir with gradual clinical improvement. Respiratory viral PCR testing should be considered in patients with features of lower respiratory tract infection and rhabdomyolysis as this can detect influenza B and other viruses which cannot be detected by doing H1N1 PCR

    SFRP4 signalling of apoptosis and angiostasis uses nitric oxide-cGMP-permeability axis of endothelium

    Nitric oxide (NO) plays a critical role in endothelial functions such as cellular migration, vascular permeability and angiogenesis. Angiogenesis, the formation of new blood vessels from "pre-existing" ones is a carefully regulated process and essential during reproduction, development and wound healing. Previously our lab group reported that Secreted Frizzled-Related Protein 4 (sFRP4) could inhibit angiogenesis in both in vitro and in vivo conditions. sFRP4 belongs to a family of secreted glycoproteins that function as antagonists of the canonical Wnt signalling pathway. Although the pro-apoptotic role of sFRP4 is well discussed in literature, little is known in regards to its anti-angiogenic property. The objective of this study was to elucidate sFRP4 implications in NO biology of the endothelium. Results demonstrate that sFRP4 causes endothelial dysfunction by suppressing NO-cGMP signaling and elevating corresponding ROS levels. The imbalance between NO and ROS levels results in apoptosis and subsequent leakiness of endothelium as confirmed in vivo (Texas red/Annxin - CAM assay) and in vitro (Monolayer permeability assay) conditions. Furthermore utilizing peptides synthesized from the CRD domain of sFRP4, our results showed that while these peptides were able to cause endothelial dysfunctions, they did not cause apoptosis of the endothelial cells. Thereby confirming that sFRP4 can mediate its anti-angiogenic effect independent of its pro-apoptotic property. In conclusion, the current study reports that sFRP4-mediated anti-angiogenesis occurs as a result of impaired NO-cGMP signaling which in turn allow for elevation of redox levels and promotion of apoptosis of endothelial cells

    Assessing the effectiveness of intervention strategies to address home injuries among children in Malaysia: a cluster randomized trial evaluation of evidence

    Get PDF
    Background Malaysia is facing an increasing burden of childhood injuries, not unlike many other low- and middle-income countries (LMICs). Across the globe, more than 95 percent of total child injury mortality occurs in LMICs. A considerable proportion of these injuries occur in and around the home. Effective approaches to prevention include home safety education, parenting education and home modification. Through this study, we aim to evaluate the effectiveness of two intervention strategies in reducing in-home hazards for unintentional injuries among children. Methods We conducted a prospective cluster randomized controlled trial (cRCT) to compare the effectiveness of an in-home safety tutorial program and an educational pamphlet intervention in reducing safety hazards to child injuries. The study randomized 39 clusters to two study arms (home safety tutorial vs educational pamphlet), with around 30 households per cluster. Our exposure and outcome were assessed using a household survey instrument with self-reported and observer-reported components. Results Our initial analysis is a comparison of overall safety scores across the baseline arm that found a mean safety score of 30 of a maximum possible 45 (translating to a mean percentage of 66.7%), with improvement on average in both intervention arms. The overall safety score mean for educational pamphlets was 32.3 with a mean percentage of 71.7%, and the corresponding numbers for the in-home tutorial were 31.8 and 71%. Discussion This study compares a labor-intensive and ‘active’ intervention, the in-home safety tutorial, with a more passive intervention through handing out educational pamphlets. In our preliminary findings from the cRCT, we see an improvement in the mean safety scores between baseline and follow-up measurement in both intervention arms; between the two intervention arms, the safety scores are comparable. We believe that educational pamphlets can be an effective intervention to reduce child injuries, with particular relevance to resource constrained settings

    National, regional, and state-level burden of <i>Streptococcus pneumoniae</i> and <i>Haemophilus influenzae</i> type b disease in children in India: modelled estimates for 2000-2015

    Background: India accounts for a disproportionate burden of global childhood illnesses. To inform policies and measure progress towards achieving child health targets, we estimated the annual national and state-specific childhood mortality and morbidity attributable to Streptococcus pneumoniae and Haemophilus influenzae type b (Hib) between 2000 and 2015. Methods: In this modelling study, we used vaccine clinical trial data to estimate the proportion of pneumonia deaths attributable to pneumococcus and Hib. The proportion of meningitis deaths attributable to each pathogen was derived from pathogen-specific meningitis case fatality and bacterial meningitis case data from surveillance studies. We applied these proportions to modelled state-specific pneumonia and meningitis deaths from 2000 to 2015 prepared by the WHO Maternal and Child Epidemiology Estimation collaboration (WHO/MCEE) on the basis of verbal autopsy studies from India. The burden of clinical and severe pneumonia cases attributable to pneumococcus and Hib was ascertained with vaccine clinical trial data and state-specific all-cause pneumonia case estimates prepared by WHO/MCEE by use of risk factor prevalence data from India. Pathogen-specific meningitis cases were derived from state-level modelled pathogen-specific meningitis deaths and state-level meningitis case fatality estimates. Pneumococcal and Hib morbidity due to non-pneumonia, non-meningitis (NPNM) invasive syndromes were derived by applying the ratio of pathogen-specific NPNM cases to pathogen-specific meningitis cases to the state-level pathogen-specific meningitis cases. Mortality due to pathogen-specific NPNM was calculated with the ratio of pneumococcal and Hib meningitis case fatality to pneumococcal and Hib meningitis NPNM case fatality. Census data from India provided the population at risk. Findings: Between 2000 and 2015, estimates of pneumococcal deaths in Indian children aged 1–59 months fell from 166 000 (uncertainty range [UR] 110 000–198 000) to 68 700 (44 600–86 000), while Hib deaths fell from 82 600 (52 300–112 000) to 15 600 (9800–21 500), representing a 58% (UR 22–78) decline in pneumococcal deaths and an 81% (59–91) decline in Hib deaths. In 2015, national mortality rates in children aged 1–59 months were 56 (UR 37–71) per 100 000 for pneumococcal infection and 13 (UR 8–18) per 100 000 for Hib. Uttar Pradesh (18 900 [UR 12 300–23 600]) and Bihar (8600 [5600–10 700]) had the highest numbers of pneumococcal deaths in 2015. Uttar Pradesh (9300 [UR 5900–12 700]) and Odisha (1100 [700–1500]) had the highest numbers of Hib deaths in 2015. Less conservative assumptions related to the proportion of pneumonia deaths attributable to pneumococcus indicate that as many as 118 000 (UR 69 000–140 000) total pneumococcal deaths could have occurred in 2015 in India. Interpretation: Pneumococcal and Hib mortality have declined in children aged 1–59 months in India since 2000, even before nationwide implementation of conjugate vaccines. Introduction of the Hib vaccine in several states corresponded with a more rapid reduction in morbidity and mortality associated with Hib infection. Rapid scale-up and widespread use of the pneumococcal conjugate vaccine and sustained use of the Hib vaccine could help accelerate achievement of child survival targets in India.

    Alzheimer's disease (AD), a neurodegenerative disorder affects more than 35 million people globally. Acetylcholinesterase suppression is the common approach to enhance the well-being of AD patients by increasing the duration of acetylcholine in the cholinergic synapses. Generally, herbal secondary metabolites are reported to be a major resource for acetylcholinesterase inhibitors (AChEIs). Trans-tephrostachin was reported from Tephrosia purpurea for AChE inhibition. Here, we report on the design, synthesis, and assessment of human acetylcholinesterase inhibitory activity from trans-tephrostachin derivatives or analogs as anti-AD agents. The five newly synthesized compounds 4a. 4b, 4c, 4d and 4e displayed potent inhibitory activities with IC50 values of 35.0, 35.6, 10.6, 10.3, and 28.1 μM respectively. AChE enzyme kinetic study was performed for the five derived compounds using the Ellman's method. The Lineweaver-Burk and the secondary plots revealed the mixed inhibition for 4a, 4c and 4d whereas 4b and 4e demonstrated competitive inhibition. Molecular docking and molecular dynamics simulations showed the derivatives or analogs of trans-tephrostachin attained a high binding affinity and efficacy than the standard drug. In conclusion, trans-tephrostachin and its derivative compounds could become effective agents for further drug development to treat AD.Published versio

    Aim: To assess the usefulness of duodenoscopy in the diagnosis of duodenal ulcers in dogs. Materials and Methods: Sick dogs with chronic gastrointestinal problems were physically examined and samples were collected for haematology, biochemistry and faecal examination. Duodenal biopsies, duodenal contents and brush cytology were obtained via duodenoscopy. Results: Seven duodenal ulcers cases were recorded, higher incidences was recorded in Labrador retriever, 2-4 years of aged male dogs. Significantly decreased Hb (9.10 &amp;#177; 0.25 g/dl), RBCs (4.39 &amp;#177; 0.19 mill/cu.mm) and albumin (2.343b &amp;#177; 0.13 g/dl) level were noticed. Hyperaemia with ulceration of duodenal mucosa was observed. Conclusion: Duodenoscopy is very much useful for detection of duodenal ulceration and provided a sensitive technique for early diagnosis of mucosal lesions and ulceration. [Vet.

    The epidemiology of infection-related glomerulonephritis (IRGN) is changing in recent times both in developed and developing nations. Although published studies showed renal outcome in adult IRGN was not as benign as in children, literature regarding clinical profile and outcome of crescentic form of adult IRGN is scarce; hence, we aimed to study the clinical profile of crescentic IRGN. We conducted a retrospective observational study in patients with crescentic IRGN in adults at the Department of Nephrology, Madras medical college, Chennai between 2009 and 2014. A total of 47 patients were included with a mean follow-up of 9.9 ± 4.2 months. The mean age was 42 ± 13.5 years. About 19.1% of patients had diabetes. The skin was the most common site of infection (38.3%) with methicillin-resistant Staphylococcus acareas (MRSA) as the most common organism. Hypocomplementemia was present in 100% in our study. Hemodialysis (HD) was required in 53.2% of patients and oral steroids were given in 78.7%. Complete renal recovery was seen only in 25.5%, progression to chronic kidney disease in 40.4%, seven patients reached end-stage renal disease, and nine patients died during follow-up. On univariate analysis, MRSA infection, the unidentified source of infection, nonisolation of organisms presence of interstitial fibrosis and tubular atrophy in renal biopsy and requirement of HD were found to be significant risk factors for poor renal outcome. In our study, crescentic form of IRGN is associated with poor renal outcome
