BACKGROUND: Tight glycaemic control in people with type 2 diabetes can lead to a reduction in microvascular and possibly macrovascular complications. The use of near-patient (rapid) testing offers a potential method to improve glycaemic control. AIM: To assess the effect and costs of rapid testing for glycated haemoglobin (HbA1c) in people with type 2 diabetes. DESIGN OF STUDY: Pragmatic open randomised controlled trial. SETTING: Eight practices in Leicestershire, UK. METHOD: Patients were randomised to receive instant results for HbA1c or to routine care. The principal outcome measure was the proportion of patients with an HbA1c <7% at 12 months. We also assessed costs for the two groups. RESULTS: Of the 681 patients recruited to the study 638 (94%) were included in the analysis. The mean age at baseline was 65.7 years (SD = 10.8 years) with a median (interquartile range) duration of diabetes of 4(1-8) years. The proportion of patients with HbA1c < 7% did not differ significantly between the intervention and control groups (37 versus 38%, odds ratio 0.95 [95% confidence interval = 0.69 to 1.31]) at 12 months follow up. The total cost for diabetes-related care was 390 UK pounds per patient for the control group and 370 UK pounds for the intervention group. This difference was not statistically significant. CONCLUSION: Near-patient testing for HbA1c alone does not lead to outcome or cost benefits in managing people with type 2 diabetes in primary care. Further research is required into the use of rapid testing as part of an optimised patient management model including arrangements for patient review and testing. 相似文献

Management of Head and Neck Cancers poses a challenge inspite of several advances because of poor success in terms of response
rate, survival and reduced morbidity of the patients. In the present study 30 untreated histologically proven cases of head
and neck cancers were subjected to weekly radiotherapy with adjuvant chemotherapy (cisplatin 30 mg/m2 intravenously). This study group was compared with a group of 30 patients who were given only radiotherapy. Results have
shown that combination of chemotherapy with radiotherapy gives a significantly better results in tumour as well as nodal response
with minimal toxicities. 相似文献

Melioidosis is endemic in the South Asian regions, like Thailand, Singapore Malaysia and Australia. The disease is more pronounced in the southern part of the country. It is caused by Burkholderia pseudomallei which causes systemic involvement, morbidity and mortality associated with the disease is high. Due to highly varied clinical presentation, and low general awareness this infection is largely underdiagnosed and under reported in our country. Most laboratories in the country still rely on conventional culturing methods with their low sensitivity, adding to the under reporting. To enhance physician awareness we describe here two cases who presented to our institute after months of misdiagnosis. 相似文献

Diagnosis and Management of Atypical Hemolytic Uremic Syndrome In Children: Single Centre Experience
Rashmi D. Patel Aruna V. Vanikar Manoj R. Gumber Kamal V. Kanodia Kamlesh S. Suthar Himanshu V. Patel Hargovind L. Trivedi 《Indian journal of hematology & blood transfusion》2014,30(4):342-346
Atypical hemolytic uremic syndrome (aHUS) although rare is the commonest cause of acute renal failure (ARF) in children and has poor prognosis. We present single centre experience of aHUS. Thirty six children (29 males, 7 females) with mean age, 7.9 years presented with ARF, 2 children also had tonic–clonic type convulsions. Their hematology examination revealed hemolytic anemia with s. creatinine (SCr), 5.54 mg/dl. Acute HUS was observed in 75 %, acute on chronic HUS in 19.4 % and patchy cortical necrosis (PCN) in 5.6 % biopsies. Mean 5.4 plasma exchanges (PE) were carried out. Supportive management of anti-hypertensives and prednisone was also given. Recovery end points were establishment of urine output, improvement of SCr and hematological profile. Hematology and renal function profile improved variably in all children, 5.6 % died, relapse was observed in 80.5 % over mean 70 days; 13.9 % children are doing well over mean follow-up of 268.8 days. Thus poor prognosis was observed in 86.1 % children. Children with acute on chronic HUS and PCN did not recover. Six children who recovered had acute HUS. aHUS in Indian children occurs at an older age of around 8 years and chronic/irreversible changes on histopathology examination are harbingers of poor prognosis. PE is life-saving however further research for developing strategies to improve long-term survival is needed. 相似文献

The Sultanate of Oman has experienced an epidemiological transition over the last 4 decades with rising tide of non-communicable disease such as type-2 diabetes. This study aims to estimate the prevalence of pre-diabetes and explore the associated demographic, clinical and biochemical risk factors among a semi-urban Omani population. A semi-urban satellite town, Bidbid, located about 30 km west of the capital, Muscat, was selected as the study setting. The targeted participants were Omani adults (18 to 60 years old) who had resided in Bidbid municipality for at least 6 months prior to enrollment in the study. Using multistage random sampling, 1,600 Bidbid residents were invited to participate in the study. The study protocol gathered data on the socio-demographic and clinical backgrounds of the participants. Participants’ impaired glucose tolerance (IGT) impaired fasting glucose (IFG) and cholesterol and triglyceride levels were then measured. The study surveyed 1,313 individuals (490 men and 823 women) out of 1,600 who had been invited to participate. The participation rate was higher among women than men (91.5% compared to 54.3%). A total of 459 individuals (35% of participants) were diagnosed as pre-diabetic by either the IGT or IFG test; 121 (9%) were pre-diabetic by virtue of both measurements. Male gender, advanced age and obesity were each independently associated with higher prevalence of pre-diabetes. Increased prevalence of pre-diabetes also correlated with the indices of hypercholesterolemia and dyslipidaemia. Pre-diabetes is a substantial health problem in Oman that may present a significant challenge to the national healthcare system in the near future. Customized interventions targeting groups with high risk of pre-diabetes, especially men, the elderly and the obese, are urgently needed. 相似文献

We report an adult patient with a left ventricular pseudoaneurysm following an acute myocardial infarction in whom three-dimensional (3-D) transesophageal echocardiography (TEE) delineated clearly not only the location but also the size and shape of the rupture site. The size of the rupture site measured by 3-D TEE correlated well with the surgical measurements. Three-dimensional images also showed a localized superior distortion of the lateral aspect of the mitral annulus and left atrial wall produced by the pseudoaneurysm. The resulting severe mitral regurgitation practically disappeared after repair and decompression of the pseudoaneurysm. 相似文献
