AimsThe prevalence of premature coronary artery disease (CAD) in India is two to three times more than other ethnic groups. Untreated heterozygous familial hypercholesterolemia (FH) is one of the important causes for premature CAD. As the age advances, these patients without treatment have 100 times increased risk of cardiovascular (CV) mortality resulting from myocardial infarction (MI). Recent evidence suggests that one in 250 individuals may be affected by FH (nearly 40 million people globally). It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown.MethodsA total of 635 patients with premature CAD were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Based on scores, patients were diagnosed as definite, probable, possible, or no FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded.ResultsOf total 635 patients, 25 (4%) were diagnosed as definite, 70 (11%) as probable, 238 (37%) as possible, and 302 (48%) without FH, suggesting the prevalence of potential (definite + probable) FH of about 15% in the North Indian population. FH is more common in younger patients, and they have lesser incidence of common CV risk factors such as diabetes, hypertension, and smoking than the younger MI patients without FH (26.32% vs.42.59%; 17.89% vs.29.44%; 22.11% vs.40.74%).ConclusionFH prevalence is high among patients with premature CAD admitted to a cardiac unit. To detect patients with FH, routine screening with simple criteria such as family history of premature CAD combined with hypercholesterolemia, and a DLCN criteria score >5 may be effectively used. 相似文献

本文试用对大肠杆菌菌液的不同浓度,进行系列微菌落计数分析。发现采用既定公式:DMSCC/ml=FWF×计数的总细菌数,计数后偏差较大。若用该数据进行常规平板倾注法和微菌落-酶联免疫吸附法(MC-ELISA)相关性比较,得R~2=-0.056。而用修正公式:DMSCC/ml=FWF×计数的总细菌数×1/菌液稀释倍数,得两法相关系数r=0.99936,经相关系数检验,P<0.01,说明修正正确。 相似文献

用不同宽度袖带测定一组儿童血压,证实了袖带宽度可明显影响血压测得值的精确度,并由此推导出不适宜袖带测压值的校正公式。在另两组儿童血压测定中检验了该校正公式的有效性及可行性。血压校正公式的提出,使实施美国心脏学会建议的臂中点周径百分之四十为适宜袖宽的标准成为可能。血压校正公式应用简便,可在儿童医疗预防、卫生保健、特别是各种血压调查、科研协作中发挥积极作用。 相似文献

Patients and methods: In order to better define the potential advantages and risks of laser in situ keratomileusis (LASIK), we designed a prospective
study including 73 eyes.
Results: After 6 months, 62 eyes were examined. Myopia was corrected from –6.10 ± 3.12 (mean ± standard deviation) to + 0.04 ± 0.66
D, with 54 eyes (87.1 %) being within ± 1.00 D of emmetropia. Astigmatism was corrected from –1.07 ± 1.02 to –0.32 ± 0.89
D. Uncorrected visual acuity was 0.5 or better in 59 eyes (95.2 %) and 1.0 or better in 27 eyes (43.5 %) 6 months postoperatively.
More than one line in best-corrected visual acuity was lost by 6 eyes (9.7 %), with most of these eyes being highly myopic.
There was no change or a gain in lines in best corrected visual acuity in 42 eyes (66.1 %). Intraoperative complications arose
in two eyes (2.7 %); in one eye, visual acuity was temporarily decreased. More treatments were performed in 7 eyes (9.6 %).
Postoperatively, no haze, scars or central islands were detected. Patient satisfaction after LASIK was high: 97.3 % were pleased
or very pleased with the result.
Conclusions: In conclusion, LASIK is effective in the correction of myopia and myopic astigmatism. Although complications more frequently
occurred in the correction of higher refractive errors, LASIK seems to be relatively safe compared with other refractive methods.

The Beneficial Effect of Low Initial Dose and Gradual Increase of Erythropoietin Treatment in Hemodialysis Patients 总被引:1,自引:0,他引:1
Abstract: It is well known that the effects of human re-combinant erythropoietin (rHuEPO) are dose-dependent. However, when higher doses of rHuEPO are used, the frequency of the side effects also increases. The aim of our study was to analyze the hematologic parameters and blood pressure response in hemodialysis patients treated with low initial and gradually increased rHuEPO. Sixteen regular hemodialysis patients were treated with 3 times 20 U/kg/week of rHuEPO subcutaneously during the first month. Every fourth week the dose was increased by 3 times 20 U/kg/week if the hematocrit did not rise by 2%. If the elevation was 2% or more, the dose of the rHuEPO was not changed. Blood count and blood pressure were checked every week. The antihypertensive treatment was also reviewed weekly. The hematocrit increased significantly from the second week, and 11 patients achieved the target level (30%) between Weeks 8 and 24. Two patients reached the 30% hematocrit level between Weeks 2 and 8, and another 2 patients reached the target level between Weeks 25 and 28. There was 1 nonresponder. The average rHuEPO dose needed to achieve the target hematocrit was 56.3 U/kg/week. We did not observe significant changes in the mean arterial or diastolic blood pressure. It was necessary to increase the doses of anti-hypertensive drugs, namely nifedipine and captopril, to control blood pressure. Encephalopathy occurred in none of the cases. The low initial dose and the gradual increase of rHuEPO treatment were beneficial to the hemodialysis patients. Although the target hematocrit took longer to achieve, high blood pressure and encephalopathy were prevented by close monitoring and administration of suitable antihypertensive treatment. 相似文献

为217 例鼻中隔偏曲患者行鼻中隔偏曲矫正术,9 例术中出现鼻中隔粘骨膜对位性穿孔,经及时用游离下鼻甲粘膜瓣修复,其修复要点是(1)继续分离中隔穿孔周围粘骨膜,去除穿孔周围的偏曲骨质,以完成中隔矫正术,并扩大放置鼻甲粘膜瓣的空间;(2)取下鼻甲粘膜瓣较正常的部分,要略大于中隔穿孔的大创孔面积,光滑粘膜面可修整使之较为粗糙,以利粘膜瓣生长。8 例修复成功,仅1 例发生术后中隔穿孔。 相似文献
