Two hundred and twenty one cases of viperine envenomation, who presented to hospital without specific treatment, seen over an twenty five years period, have been presented. Mild, moderate and severe envenomation was encountered in 33 per cent, 47 per cent and 20 per cent respectively. Bites on feet and ankles were seen in 85.5 per cent of cases. The average time interval between bite and hospitalisation was 4.8 hours, range being 15 minutes to 7 days. Local swelling was observed in 97.7 per cent, hematuria in 62 per cent, mucosal haemorrhages in 24.8 per cent and haematemesis in 19 per cent of patients. Average Antisnake Venom (ASV) required in mild, moderate and severe envenomation was 50 ml, 147.5 ml and 324 ml respectively. Major complications observed were renal failure in 10, intracompartmental syndrome in 3, intracerebral bleed and septicaemia in 2 each. One patient each developed finger gangrene, osteomyelitis, perirenal haematoma, sinus bradycardia and uncontrolled bleeding. Blood transfusion was required in 32 patients. Reactions to ASV were seen in 12 patients and overall there were 5 deaths.KEY WORDS: Antisnake venom, Viperine envenomation 相似文献

Anderson-Fabry (FD) disease is a rare X-linked disorder caused by different mutations in the Galactosidase α (GLA) gene, which leads to α-galactosidase A enzyme deficiency and the storage of glycosphingolipids in different kinds of organs, included the heart. This results in myocardial inflammation and left ventricular hypertrophy (LVH) and fibrosis. Echocardiography and cardiac magnetic resonance (C-MRI), in particular with new techniques, such as mapping analysis, late gadolinium enhancement (LGE) assessment and strain imaging, are important tools that allow a correct diagnosis, discriminating FD from other hypertrophic heart conditions. C-MRI is able to detect tissue alterations in the early stages of the disease, when an appropriate treatment could be more effective, and it has a fundamental role in monitoring therapy. 相似文献

常用抗高血压药物对血压的时间生物学特征的影响 总被引:1,自引:0,他引:1
目的 :探讨 3类常用抗高血压药物对非杓型的高血压病患者BP的时间生物学特征的影响。方法 :共入选非杓型BP分布的高血压病患者 16 1例 ,将其随机分为 3组 ,分别给予赖诺普利 (10mg·d-1) ,非洛地平 (2 5mg·d-1) ,或氢氯噻嗪 (5 0mg·d-1) ,并于治疗前后行 2 4h动态BP监测。采用余弦拟合方法分析治疗前后患者BP时间生物学特征的改变。结果 :赖诺普利组与非洛地平组治疗后 2 4hBP均值明显降低 ,但其振幅、峰值相位无变化 ;氢氯噻嗪治疗降压效果不甚理想 ,但显著增加了患者BP的夜间降低幅度 ,使患者BP由非杓型转变为杓型分布。结论 :氢氯噻嗪治疗可能使非杓型分布的高血压病患者的BP转变为杓型分布 ,从而有助于降低患者相关并发症的发生率。 相似文献

The first purpose of the present study was to investigate the effect of three different preexercise meals on perceived exertion and glycaemia during a one-hour bicycle exercise at 80% VO2 max. The second purpose of this study was to determine the relationship between glycaemia and perceived exertion. Eight athletes (age: 24.6 ± 2.7 years, weight: 78.0 ±6.8 kg, height: 182.6 ± 9.9 cm) completed three assessment sessions, each being preceeded by one of the following meals, ingested 3 h before exercise: 400 mL of water, 400 mL of water and 75 g of glucose, and 100 mL of water and 375 g of potatoes. The subjects 'perceived exertion were measured at times 6, 15, 30, 45, 60 min and glycaemia at 0, 30, 60 min of the exercise. The results showed that perceived exertion (RPE and ETL) of each meal increased as a function of time (P <- 0.05) whereas glycaemia did not differ except for the glucose meal between 30 min and 1 h(P < 0.02). There was no significant difference in ratings of perceived exertion among any meal whereas glycaemia was different between the three conditions only at the beginning and the middle of the exercises (P < 0.04 and P < 0.02, respectively). Moreover, the vectorial angles between the variables ofperceived exertion and the glycaemia are close to 90 °. These results would suggest that perceived exertion does not seem to be affected by the three preexercise meals used in our study. Perceived exertion is not correlated to glycaemia changes during one-hour high intensity exercise. The results would, therefore, suggest that glycaemia is not a contributor signal of perceived exertion in this study. It seems that physiological factors other than glycaemia may have mediated the perceptual intensity at exhaustion. The respiratory-metabolic signals of exertion which are most pronounced at high relative exercise intensity are suggested to influence the perceptual signal of exertion. 相似文献
