IntroductionAcetabulum fractures, though relatively uncommon, are associated with significant morbidity and mortality. These involve high energy trauma and due to their complex nature, the management requires understanding the relevant surgical anatomy, defining the injury via appropriate radiographic assessment and determining a suitable treatment plan. Literature is scarce for the demographic data, fracture patterns, associated injuries, management and early complications in the Indian scenario. These factors play a pivotal role in the ultimate recovery of the patients. Therefore this study was conceptualised to assess the epidemiology and evaluate the complications of these fractures. Furthermore the effects of various factors determining the quality of reduction in surgically treated patients were also assessed.MethodologyThis was a prospective observational study in which patients presenting to the advance trauma centre of our institute with acetabulum fractures were included. Demographical data of the patients, mechanisms of injuries, fractures morphologies, complications and radiological outcomes were recorded prospectively.Results116 patients with acetabular fractures were included in the study. 81% of these were males, with average age of 39.95 ± 15.87 years; with road traffic accidents being the predominant mode of injuries. Mortality was reported in 5 patients; 4 patients had deep venous thrombosis and sciatic nerve injuries were seen in 12 patients of which 4 were iatrogenic. 8 patients had some form of infection, out of which 4 required multiple debridements. 4 cases developed heterotrophic ossification while 2 cases had loss of reduction. The timing of surgery and other associated fractures had significant effect on the quality of reduction (p < 0.05); while age, gender, mode of injury or individual fracture patterns had no such effect.ConclusionsProper radiological assessment and evaluation of fracture configuration is important for management of acetabulum fractures. When indicated, this should be followed by early open reduction and internal fixation to achieve anatomical reduction, with management of associated injuries for better outcomes. 相似文献
Bipolar disorder (BD) is frequently associated with immune dysfunctions. Studying the genetic diversity of the immuno-modulatory human leukocyte antigen (HLA)-G locus in a French BD cohort, we previously reported an association between a functionally relevant 14 bp Ins/Del polymorphism and BD risk. The present study investigated the genetic and expression diversities of HLA-G in a geographically distinct South Indian population-group BD patients, as well as the influence of exposure to the neurotropic Toxoplasma gondii pathogen. Three functionally relevant HLA-G polymorphisms, i.e. HLA-G 14 bp Ins/Del (rs66554220), +3142G>C (rs1063320) and +3187A>G (rs9380142) were genotyped by polymerase chain reaction (PCR) and real-time PCR. Sub-samples of BD patients and healthy controls (HC) were investigated for plasma levels of soluble HLA-G (sHLA-G) isoforms, as well as circulating stigma of T. gondii infection.
Findings indicate: (i) the frequency of the HLA-G 14 bp Del/Del genotype was higher in BD cases, as compared to HC; (ii) the HLA-G + 3142 C allele and CC genotype were more prevalent in BD patients than in HC; (iii) sHLA-G levels were significantly higher in BD cases, especially in females and in the early onset sub-group; and (iv) the InsGA haplotype was more prevalent in HC.
Our findings further support the genetic contribution of HLA-G to BD risk, as well as indicate relevant expression profiles. Such data may also indicate a potential developmental role in BD etiology, given that HLA-G is an important immune regulator from the intrauterine period and across development. 相似文献
The Comoros Islands are situated off the coast of East Africa, at the northern entrance of the channel of Mozambique. Contemporary Comoros society displays linguistic, cultural and religious features that are indicators of interactions between African, Middle Eastern and Southeast Asian (SEA) populations. Influences came from the north, brought by the Arab and Persian traders whose maritime routes extended to Madagascar by 700–900 AD. Influences also came from the Far East, with the long-distance colonisation by Austronesian seafarers that reached Madagascar 1500 years ago. Indeed, strong genetic evidence for a SEA, but not a Middle Eastern, contribution has been found on Madagascar, but no genetic trace of either migration has been shown to exist in mainland Africa. Studying genetic diversity on the Comoros Islands could therefore provide new insights into human movement in the Indian Ocean. Here, we describe Y chromosomal and mitochondrial genetic variation in 577 Comorian islanders. We have defined 28 Y chromosomal and 9 mitochondrial lineages. We show the Comoros population to be a genetic mosaic, the result of tripartite gene flow from Africa, the Middle East and Southeast Asia. A distinctive profile of African haplogroups, shared with Madagascar, may be characteristic of coastal sub-Saharan East Africa. Finally, the absence of any maternal contribution from Western Eurasia strongly implicates male-dominated trade and religion as the drivers of gene flow from the North. The Comoros provides a first view of the genetic makeup of coastal East Africa. 相似文献
OBJECTIVES: To estimate the prevalence and incidence of type 2 diabetes among American Indian youth. STUDY DESIGN: Medical records were reviewed annually for all patients with diabetes who were <20 years of age at 6 Indian Health Service facilities in Montana and Wyoming. All cases < or =5 years of age or weight per age < or =10th percentile at diagnosis or with islet cell antibodies were considered as probable type 1. Among the remaining cases, probable type 2 diabetes was defined when a child had one or more of the following characteristics: weight per age > or =95th percentile or acanthosis nigricans at diagnosis, elevated C-peptide or insulin, family history of type 2 diabetes; treatment with oral agents with or without insulin or no hypoglycemic therapy after 1 year of follow-up. RESULTS: From 1999 to 2001, 53% of prevalent cases and 70% of incident cases were categorized as probable type 2 diabetes. The average annual prevalence of probable type 1 and type 2 diabetes was 0.7 and 1.3 per 1000. The average annual incidence rates for probable type 1, and type 2 diabetes were 5.8, 23.3 per 100,000. CONCLUSIONS: The incidence of probable type 2 diabetes was approximately 4 times higher than type 1 diabetes among American Indian youth in Montana and Wyoming 相似文献
We have analysed the hypervariable regions (HVR I and II) of human mitochondrial DNA (mtDNA) in individuals from Uttar Pradesh (UP), Bihar (BI) and Punjab (PUNJ), belonging to the Indo-European linguistic group, and from South India (SI), that have their linguistic roots in Dravidian language. Our analysis revealed the presence of known and novel mutations in both hypervariable regions in the studied population groups. Median joining network analyses based on mtDNA showed extensive overlap in mtDNA lineages despite the extensive cultural and linguistic diversity. MDS plot analysis based on Fst distances suggested increased maternal genetic proximity for the studied population groups compared with other world populations. Mismatch distribution curves, respective neighbour joining trees and other statistical analyses showed that there were significant expansions. The study revealed an ancient common ancestry for the studied population groups, most probably through common founder female lineage(s), and also indicated that human migrations occurred (maybe across and within the Indian subcontinent) even after the initial phase of female migration to India. 相似文献
Citation Best LG, Nadeau M, Davis K, Lamb F, Bercier S, Anderson CM. Genetic variants, immune function, and risk of pre‐eclampsia among American Indians. Am J Reprod Immunol 2012; 67: 152–159 Problem To determine the prevalence in an American Indian population of genetic variants with putative effects on immune function and determine if they are associated with pre‐eclampsia (PE). Method of study In a study of 66 cases and 130 matched controls, six single nucleotide polymorphisms (SNP) with either previously demonstrated or postulated modulating effects on the immune system were genotyped. Allele frequencies and various genetic models were evaluated by conditional logistic regression in both univariate and multiply adjusted models. Results Although most genetic variants lacked evidence of association with PE, the minor allele of the CRP related, rs1205 SNP in a dominant model with adjustment for age at delivery, nulliparity, and body mass index, exhibited an odds ratio of 0.259 (95% CI of 0.08–0.81, P = 0.020) in relation to severe PE (48 cases). The allelic prevalence of this variant was 46.1% in this population. Conclusion Of the six SNPs related to immune function in this study, a functional variant in the 3′UTR of the CRP gene was shown to be associated with severe PE in an American Indian population. 相似文献
Medicinal plants based traditional systems of medicines are playing important role in providing health care to large section of population, especially in developing countries. Interest in them and utilization of herbal products produced based on them is increasing in developed countries also. To obtain optimum benefit and to understand the way these systems function, it is necessary to have minimum basic level information on their different aspects. Indian Systems of Medicine are among the well known global traditional systems of medicine. In this review, an attempt has been made to provide general information pertaining to different aspects of these systems. This is being done to enable the readers to appreciate the importance of the conceptual basis of these system in evolving the material medica. The aspects covered include information about historical background, conceptual basis, different disciplines studied in the systems, Research and Development aspects, Drug manufacturing aspects and impact of globalization on Ayurveda. In addition, basic information on Siddha and Unani systems has also been provided. 相似文献
