Each patient was matched for heart rate and stroke volume with a control patient who had normal left ventricular end-diastolic pressure and coronary arteries. All 20 patients underwent right and left cardiac catheterisation. In patients with constrictive pericarditis compared with controls, the median (range) left ventricular peak diameter lengthening rate, normalised for end-diastolic dimension, was 4.5 (2.5-8.0) s-1 and 2.9 (1.6-4.1) (p less than 0.01), and the rapid filling period fraction of diastole was 0.28 (0.18-0.37) and 0.37 (0.21-0.58) (p less than 0.05), while the mitral valve E-F slope was 20.1 (10.5-39.2) cm/s and 11.8 (7.6-14.5) (p less than 0.05), respectively. Thus, the early rate of left ventricular diameter lengthening is increased in constrictive pericarditis independent of heart rate and stroke volume, while the actual duration of the rapid filling period is decreased. These results, obtained noninvasively, extend the findings of previous invasive studies. The method may help in the difficult clinical diagnosis of constrictive pericarditis, although there is some overlap with the normal control range.</p>","PeriodicalId":8084,"journal":{"name":"Annals of clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14325206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Up to this century the sauna was widely used as a place for childbirth. But the main reason for a sauna is the pleasure of sauna bathing and the craving for the feeling after the sauna. The longevity and effects of the sauna in Finland are linked to the view of the sauna as a holy place; participants have to behave in the sauna as they would in the church. The use of the vihta or vasta (a sauna whisk made of birch branches) has been an essential part of sauna bathing. Beating with the vihta promotes sweating and stimulates the warm skin. Many curative and magical effects have been attributed to the practice. Seldom has the sauna been thought to cause any disease.</p>","PeriodicalId":8084,"journal":{"name":"Annals of clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14348774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Respiratory syncytial virus (RSV) accounted for half of the positive viral results. Skin prick tests were performed after the second episode of bronchial obstruction. Of the 79 children tested, 57% had at least one positive result to house dust mite allergen and/or to one of the four seasonal allergens studied. Reactivity to birch pollen was most common. There was no significant correlation between the frequency of episodes in children with birch, timothy grass and mugwort pollens or with Cladosporium herbarum allergies and counts of the respective pollens or spores in the air. Blood eosinophilia was found in 34% of cases immediately after the episodes, but no seasonal variation occurred.

Can differences in cerebral and coronary autoregulation and O2-extraction explain why antihypertensive treatment prevents stroke but not myocardial infarction? 大脑和冠状动脉自动调节和o2提取的差异能否解释为什么抗高血压治疗可以预防中风而不能预防心肌梗死?

The brain is thus better suited than the heart to take advantage of the beneficial effect of antihypertensive treatment in terms of protection against hypertensive organ damage.

Therapeutic applications of drugs acting on alpha-adrenoceptors. 作用于肾上腺素受体的药物的治疗应用。

{"title":"Therapeutic applications of drugs acting on alpha-adrenoceptors.","authors":"E MacDonald,&nbsp;H Ruskoaho,&nbsp;M Scheinin,&nbsp;R Virtanen","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>For over a decade it has been known that clonidine and alpha-methyldopa lower blood pressure by activating central and peripheral alpha-2-adrenoceptors and prazosin likewise by antagonizing alpha-1-adrenoceptors. During the 1980s, the number of therapeutic indications for drugs which act via these classes of alpha-adrenoceptors has expanded greatly, particularly the non-cardiovascular applications of drugs acting on alpha-2-adrenoceptors. Novel alpha-2-agonists such as detomidine and medetomidine have been introduced into veterinary medicine as sedative/analgesics. It is possible that these and other compounds with better alpha-2-adrenoceptor selectivity than clonidine may be used in human medicine to ease symptoms of anxiety in drug- and alcohol-related withdrawal syndromes, and as preanaesthetic agents. Several novel alpha-2-adrenoceptor antagonists, such as idazoxan and atipamezole, have been developed with improved selectivity compared to the traditional antagonist at these receptors, yohimbine. At present none of these new compounds are registered for use, but several are undergoing clinical trials for a variety of therapeutic applications such as depression (idazoxan), arousal of animals sedated with alpha-2-agonists (atipamezole), and adult-onset diabetes (DG-5128). The established use of yohimbine in the treatment of male sexual impotence has been reconfirmed and several of the above compounds may be evaluated in the future to treat this disorder.</p>","PeriodicalId":8084,"journal":{"name":"Annals of clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14042339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sauna and alcohol. 桑拿和酒精。

The exact number of these accidents is not known, but in Finland (population 4.8 million) the consumption of alcohol has been estimated to be a contributing factor in some 20 to 25 sauna-related deaths every year. The scientific information on the interaction of sauna and alcohol on human physiology is totally lacking. Thus our discussion on the physiological and medical consequences of this interaction relies merely on presumptions. Ingestion of large amounts of alcohol while sauna bathing may affect the body's ability to maintain blood pressure. In particular, the risk of an orthostatic hypotensive reaction is increased with concomitant faintings and accidents. Alcohol intoxication and particularly the hangover phase exposes a person to cardiac arrhythmias, and sauna may further increase the arrhythmia-risk due to enhanced adrenergic activity. Sauna bathing and heavy drinking, and also sauna bathing during hangover phase undoubtedly create real health risks.</p>","PeriodicalId":8084,"journal":{"name":"Annals of clinical research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14346787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
