American law requires a written consent, which is free of undue influence, the subject being instructed that he is free to withdraw from the trial. In German law, an orally given consent is sufficient for therapeutic trials. With minor or incompetent research subjects, informed consent to therapeutic clinical experimentation has to be given by their parents or guardians, the permissibility of which, in other trials, is controversial. In non-therapeutic trials, blind studies, double-bind studies, and trials involving placebos, special attention has to be paid to the risk-benefit analysis and to informed consent, which in these cases, even in Germany, must be written. The most outstanding feature of American law of clinical trial is that the experimentation is subject to previous control and approval by institutional review boards. The most interesting difference in German law is the investigator's duty to effect an insurance against the risks of the research subject's death or invalidity.</p>","PeriodicalId":77932,"journal":{"name":"Pediatric pharmacology (New York, N.Y.)","volume":"3 3-4","pages":"353-9"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17732303","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}
{"title":"Legal requirements for drug testing in children in Germany.","authors":"H Hasskarl","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Since 1966 the problem of evaluation of drugs for use in man has increasingly become the subject of both international and national consideration. It was generally felt, that there is a need for a special protection for children being the subjects of the clinical evaluation of drugs. A new impulse with regard to the protection of children was recently set by the Council for International Organizations of Medical Sciences. German legislation has included these international convictions and recommendations pertaining to the performance of clinical trials. Articles 40 and 41 of the German Drug Law of 1976 are an emanation of WHO principles as well as of the Declaration of Helsinki. These articles include special provisions for the protection of children as volunteers of clinical trials, because clinical trials in children are indispensable for research on diseases of children. It is laid down in the Law that children should never be subject of research that might equally well be carried out on adults. The willing cooperation and, as far as feasible, consent of the child and its custodians has to be sought. The German Law provides that trials in healthy children may take place only with regard to diagnostic and prophylactic drugs, not with regard to the therapeutics. Article 41 of the German Drug Law permits the clinical evaluation of drugs in ill children. Therapeutic drugs may, however, be tested in children only under the condition that the drug is determined to cure the special disease under which the child is suffering. Special aspects of the clinical evaluation of drugs in children, not contained in the law, need further discussion and clarification.</p>","PeriodicalId":77932,"journal":{"name":"Pediatric pharmacology (New York, N.Y.)","volume":"3 3-4","pages":"361-6"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17732304","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 TDM service must be supervised and further developed by a responsible group of experts, for example, a section or department of clinical pharmacology that should also provide service to help the physicians to take full advantage of the system.

However both substances have goitrogenic properties in rats on low-iodine diet. They lower T4 serum levels and inhibit TSH- and GH-release probably by enhancing hypothalamic somatostatin secretion. The retrospective study described here was carried out in an attempt to clarify whether treatment of premature children with methylxanthines has adverse effects on thyroid function. The results are as follows: 1) There is no significant correlation between caffeine- and theophylline-concentrations and circulating T4 levels in single blood specimen of unselected premature infants. 2) In none of the infants was a low T4-serum value accompanied by a rise in serum TSH during methylxanthine treatment. Thus methylxanthines are not associated with the induction of primary hypothyroidism but the possibility of tertiary hypothyroidism cannot be excluded. In order to avoid adverse effects on thyroid function the lowest therapeutically active dose should be chosen.</p>","PeriodicalId":77932,"journal":{"name":"Pediatric pharmacology (New York, N.Y.)","volume":"3 3-4","pages":"267-72"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17732298","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}
