This study is the first to demonstrate both the presence of circulating miRNAs in lymph and the alteration of specific miRNAs in AP. Furthermore, these miRNAs alter in rat and human AP plasma and have potential to be explored as novel biomarkers of pancreatitis.
Limited data are available on the electrocardiogram and ambulatory electrocardiogram recording (Holter) in children infected with the human immunodeficiency virus type 1 (HIV-1). The purpose of this study was to estimate the prevalence and cumulative incidence of rhythm and conduction abnormalities in HIV-1-infected children. Electrocardiograms and Holter monitoring studies were performed annually on 205 HIV-1-infected children enrolled after 28 days of life (group I), 93 HIV-1-infected infants enrolled during pregnancy or during the first 28 days of life (group IIa), and 463 HIV-1-uninfected infants enrolled during pregnancy or during the first 28 days of life (group IIb). The 5-year cumulative incidence in the group I children of second-degree atrioventricular block or supraventricular or ventricular tachycardia was 13.4%, and the 5-year incidence was higher for the older infected group I children (16.8% for children > or =4 years old at first study and 11.4% for children <4 years, p = 0.04). The mean corrected QT interval was also longer for the older infected group I children (p = 0.002) and prolonged in the HIV-1-infected compared to the HIV-1-uninfected group II children (p = 0.02). None of the children had atrial fibrillation or flutter. Arrhythmias are uncommon in children infected with HIV-1 and in children of HIV-1-infected mothers and the arrhythmias identified tend to be benign. Therefore, routine Holter monitoring does not appear to be indicated in asymptomatic children.
Grade 1C)'. It assumes equal risk for a lumbar plexus block when compared with an upper limb plexus block and does not consider the potential benefits of ultrasound in mitigating vascular injury.In the absence of robust evidence, it is our assertion that, by identifying current practice across the country, confidence can be gained that we are operating in a way similar to our colleagues. Thus, it allows the application of the Bolam principle. For upper limb blocks, the authors recommend:(i) ultrasound-guided technique in patients with altered coagulation; (ii) INR ,2.5 (88% concordance); (iii) platelet count ≥50 000 (65% concordance); (iv) concomitant use of clopidogrel is not necessarily a contraindication (50% concordance); (v) a national audit project similar to the Royal College of Anaesthetists' third national audit project, identifying major complications of central neuraxial blockade, would be of benefit.
The lavage of the peritoneal cavity in patients with severe acute pancreatitis does not appear to confer a clinical benefit. Whether lavage of the pancreatic bed after necrosectomy is beneficial has yet to be determined.
A serious complication of replacement therapy in patients with bleeding disorders is the development of 'inhibitors', particularly FVIII inhibitors in haemophilia A patients. This leads to an increase in the management cost, morbidity and mortality, especially post-operatively. The mechanism of FVIII inhibitor development is quite complex and it is difficult to predict inhibitor development, but a prompt and accurate diagnosis is critical as early therapy can save lives. The aim of this study was to screen patients with bleeding disorders in India for inhibitors, and to analyse and compare the prevalence of inhibitors in different regions in India. Patient details were recorded and blood samples were collected in sodium citrate vacutainers from 1,505 patients with bleeding disorders, in different cities in India. Coagulation and inhibitor screening assays were performed, followed by the Bethesda assay in inhibitor positive samples to quantify the FVIII inhibitor titre. Out of the 1,505 samples analysed, 1,285 were Haemophilia A patients, out of which 78 (6.07 %) were positive for 'FVIII Inhibitors'. The highest incidence of FVIII Inhibitors was seen in South India (13.04 %). The highest incidence of 20.99 % was observed in Chennai, followed by Hyderabad (13.33 %), Jammu (9.90 %) and Guwahati (8.51 %), respectively, with respect to the samples analysed. The other regions showed an inhibitor incidence <8 %. The incidence of inhibitors in haemophilia A patients is different in different regions of India; this may be due to the intensity of treatment, type of product or the genetic characteristics of these patients.
BackgroundThough rare in occurrence, patients with rare bleeding disorders (RBDs) are highly heterogeneous and may manifest with severe bleeding diathesis. Due to the high rate of consanguinity in many caste groups, these autosomal recessive bleeding disorders which are of rare occurrence in populations across the world, may not be as rare in India.ObjectivesTo comprehensively analyze the frequency and nature of mutations in Indian patients with RBDs.MethodsPubmed search was used (www.pubmed.com) to explore the published literature from India on RBDs using the key words “rare bleeding disorders”, “mutations”, “India”, “fibrinogen”, “afibrinogenemia”, “factor II deficiency”, “prothrombin” “factor VII deficiency”, “factor V deficiency”, “factor X deficiency”, “factor XI deficiency”, “combined factor V and VIII deficiency”, “factor XIII deficiency”, “Bernard Soulier syndrome” and “Glanzmanns thrombasthenia” in different combinations. A total of 60 relevant articles could be retrieved. The distribution of mutations from India was compared with that of the world literature by referring to the Human Gene Mutation Database (HGMD) (www.hgmd.org).ResultsTaken together, 181 mutations in 270 patients with different RBDs have been reported from India. Though the types of mutations reported from India and their percentage distribution with respect to the world data are largely similar, yet much higher percentage of small deletions, duplication mutations, insertions, indels were observed in this analysis. Besides the identification of novel mutations and polymorphisms, several common mutations have also been reported, which will allow to develop a strategy for mutation screening in Indian patients with RBDs.ConclusionThere is a need for a consortium of Institutions working on the molecular pathology of RBDs in India. This will facilitate a quicker and cheaper diagnosis of RBDs besides its utility in first trimester prenatal diagnosis of the affected families.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
