Risk and protective factors in the origin of atrial septal defect secundum--national population-based case-control study.

The aim of this study was to assess the risk factors in the origin of lethal or surgically corrected isolated atrial septal defect secundum. The population-based Hungarian Case-Control Surveillance of Congenital Abnormalities (conducted between 1980 and 1996) comprised 472 atrial septal defect secundum cases, 678 matched controls and 38,151 available controls without any defects; in addition, 21,022 malformed controls with other isolated defects. Medically recorded chronic disorders in the prenatal maternity logbook were evaluated, while acute maternal diseases, drug treatments and pregnancy supplements were analyzed on the basis of both prospective medically recorded data and retrospective maternal information. Acute pelvic inflammatory disease, paroxysmal supraventricular tachycardia and phenolphthalein treatment due to severe constipation of mothers were shown to contribute to the development of atrial septal defect secundum of their children. High doses of folic acid in early pregnancy had positively influenced a minor part of isolated atrial septal defect secundum in foetuses. In conclusion, the obvious genetic predisposition for atrial septal defect secundum is connected with maternal paroxysmal supraventricular tachycardia and triggered by acute pelvic inflammatory diseases and phenolphthalein treatment, while the manifestation of atrial septal defect secundum can be reduced by high doses of folic acid supplementation in early pregnancy.

Use of a pharmaceutically adulterated dietary supplement, Pai You Guo, among Brazilian-born women in the United States.

BACKGROUND: Pai You Guo is a weight loss supplement manufactured in China and adulterated with the banned pharmaceutical products sibutramine and phenolphthalein. The US Food and Drug Administration (FDA) announced a voluntary recall of Pai You Guo in 2009, yet clinicians have noted its continued use among Brazilian-born women in Massachusetts. OBJECTIVE: To assess prevalence of Pai You Guo use, associated side effects, modes of acquisition, and impact of FDA regulatory action on these outcomes. DESIGN: Cross-sectional study using an anonymous questionnaire. PARTICIPANTS: Women ≤60 years of age, born in Brazil who attended one primary care clinic or one of six churches in Massachusetts. MAIN MEASURES: Prevalence of use, how users first heard about the product, location of purchase, associated side effects, patterns of use before and after the FDA recall. KEY RESULTS: Twenty-three percent (130/565) of respondents reported using Pai You Guo. In multivariate analysis, obesity (adj OR 3.7, p-value <0.001) and lack of insurance (adj OR 2.6, p-value 0.005) were associated with use. The majority of users (85%) reported at least one side effect. Dry mouth (59%), anxiety (29%), and insomnia (26%) were most commonly reported adverse effects. Nearly thirty-percent of users (38/130) purchased Pai You Guo from local stores and 9% (11/130) purchased it over the Internet. The majority of respondents (79/130; 61%) purchased Pai You Guo after the FDA recall. No respondent was aware of the FDA recall. CONCLUSIONS: Use of this pharmaceutically adulterated supplement is common among Brazilian-born women in Massachusetts. The FDA alerts and recall did not appear to decrease its use.

['Weight reduction preparations' from Thailand: unexpected complication for the traveller]. / 'Afslankmiddelen' uit Thailand: onverwachte reizigerszorg na terugkeer.

Two series of Thai 'slimming agents' purchased apparently without a medical consultation or prescription (one directly in Thailand and the other one indirectly in the Netherlands) were submitted for chemical analysis. Fenfluramine and diazepam were present in both series. One series also yielded phenolphtalein and vitamin B substances, while sennosides were found in the other series. Apparently travellers may unwittingly take along potent medicines when they return from far countries.
