Knowledge and perceptions of medical abortion among potential users

Great advances in surgical techniques, perfusion technology and cardiac anesthesia have made heart surgery safer. However, the mayor advance over the past 15 years has been in the field of myocardial protection. Much remains to be done in this field and there is not complete agreement about the different methods of myocardial protection. At the Institute of Cardiac Surgery of Parma a research is developing to concern three different cardioprotective strategies, of which preliminary results are showing. Three groups of patients with the same clinical, surgical, anesthesiological features, who underwent cardiac surgery have been selected. In patients of group A intermittent cold hyperkalemic crystalloid cardioplegia has been used, in those of group B intermittent cold blood cardioplegia and in those of group C intermittent cold blood cardiolegia associated a warm glucose blood cardioplegic reperfusion before aortic unclamping. In all patients enzyme levels (CPK; CPK-MB; LHD; SGOT; SGPT) were measured 12, 24, 72, 120 hours postoperatively; data were collected, also, on spontaneous return to sinus rhythm, perioperative myocardial infarction and the need or not for inotropic agents. All data at first and then those of patients who underwent only coronary rivascularization (75% of patients) were statistically analyzed (one-way Fischer's test). It appears that the use of antegrade cold intermittent blood cardioplegia with reperfusion is more optimal for myocardial protection, how show lower levels of CPK-MB especially in the first postoperative period. In group C remains greater spontaneous resumption of normal sinus rhythm compare to group A and this suggests a best preservation of cellula-integrity and function with use of blood cardioplegia.     

Proposals for a system of managing medical information

Various systems are being used for managing medical information. They have several shortcomings. Among these, one can quote: -they do not overcome the complex medical terminology and its diversity; -they do not use a common medical language -there is no easy communication between the softwares used -and so on The proposed system takes into account the multiplicity of information sources within a hospital and the need for individual decision-making from care providers.     

Knowledge and information about ADHD: evidence of cultural differences among African-American and white parents

Attention deficit hyperactivity disorder (ADHD) is considered the most common child psychiatric disorder in the United States of America. Despite the high prevalence (estimated at 3-5%), little is known about the level and source of knowledge about ADHD among those affected by the disease, and about cultural and ethnic variations in knowledge levels and information sources. This represents a serious deficit, because health behavior, including demand for health services, is thought to be strongly influenced by knowledge or beliefs held by individuals and their networks. Furthermore, recent research suggested minority children may be less likely to receive services for ADHD. To examine possible differences in ADHD knowledge and information source, a sample of 486 African-American and white parents of children at high risk for ADHD were surveyed by telephone and subsequently participated in face-to-face interviews addressing their explanatory models of ADHD. Results revealed significant ethnic differences in knowledge and sources of information about ADHD. Fewer African-American parents than white parents indicated that they had ever heard of ADHD (69% compared to 95%, P < 0.001), or that they knew some or a lot about it (36% compared to 70%, P < 0.001) African-American parents were more likely to attribute ADHD to excessive sugar in the diet than whites (59% compared to 30.0%, P < 0.001). Finally, even though the physician was listed as the most preferred information source for both groups, only 17.5% of African-American parents reported they had received information about ADHD from the physician compared to 29% of whites (P < 0.01). African American parents reported less use of and less preference for written informational materials (newspapers, journals, library) than white parents. We conclude that substantially more research should be undertaken to examine the relationship between ethnicity and ADHD knowledge, to inform culturally appropriate education campaigns and to improve access to services for this important treatable child mental health condition.     

Urinary incontinence among a 65-year old Swedish population: medical history and psychosocial consequences

The content of lipid peroxidation products (malonic dialdehyde) in the aqueous humor is increased in patients with mature cataracts developing after antiglaucoma surgery. Antioxidative activity of the humor was decreased. A relationship was revealed between the postoperative changes in ocular hydrodynamics and metabolic disorders in the chamber humor (reduction of the antioxidative activity of the humor and its suppressed production), which explains one mechanism of cataract development in patients operated on for glaucoma.     

Unnecessary medical interventions. A questionnaire study among physicians and laymen

The aim of the study was to survey attitudes among medical doctors and lay people to unsolicited medical intervention. The design of the study was an anonymous questionnaire study including three scenarios implying ethical considerations. A total of 445 medical doctors working within different areas received the questionnaire, as did 75 medical students and 600 lay people. The results showed a response rate of 67%, highest among medical doctors and students. The lay people had significantly higher expectations concerning the medical intervention in two out of three scenarios compared to medical doctors and students. The participants were offered the opportunity to comment on the questionnaire. The conclusion of the Danish survey is that there is a significantly different approach to unsolicited medical intervention among lay people compared to medical doctors and students. Medical doctors are less disposed to perform unsolicited intervention compared with the wishes/expectations of the lay people. More open attitudes and information as well as better communication is recommended.     

Knowledge about asthma among Danish primary school teachers. Results of a questionnaire study

An anonymous questionnaire inquiry performed among 324 school teachers in the Randers area with the purpose of elucidating teachers' knowledge about asthma is presented. To a series of statements about asthma, the teachers should answer yes, no or don't know. A limited knowledge about asthma in children was found. The knowledge about medicamental treatment was particularly limited. Only 57 per cent knew that wheezing after physical exertion is a strong indicator of asthma. Only five per cent had received proper instruction. This latter group had a significantly better knowledge of medical treatment (p < 0.0001-0.05). It is recommended that instruction in children's diseases, especially asthma should be reintroduced in teachers' training colleges.     

Researchers and their subjects in the history of child study: William Blatz and the Dionne quintuplets.

The social construction of children as research Ss is studied by an examination of the case of the Dionne Quintuplets in the context of child study research in the 1920s and 1930s. Two specific questions are addressed: (1) what was the nature of the relationship between researchers and Ss, and (2) what were the ethical considerations guiding the research in relation to selection and treatment of Ss. Results indicate that the 19th century tradition of baby biographies was replaced in the 1920s by increasingly invasive forms of investigation in which child Ss were isolated from normal conditions of daily living. The development of a new ethical consciousness in the late 1930s is traced to changes in professional and public opinion regarding child Ss, as well as to changes in research orientations.

Knowledge of good clinical practice among Danish physicians. A questionnaire study among hospital-employed physicians in the Copenhagen area

Differences in cord serum low density lipoprotein (LDL) composition between male and female neonates with normal or high (> or = 100 mg/dl or > or = 2.59 mmol/l) serum cholesterol levels were studied in 548 full-term newborn infants of the Toledo Study (Spain), where the absence of known perinatal factors that would alter lipid levels in cord blood was confirmed. The percentage of females with a high serum total cholesterol (TC) level was higher (p < 0.02) than that of males. ANOVA two-way analysis shows significant interaction of gender and cholesterol level upon LDL-cholesterol, triglycerides and LDL-cholesterol/Apoprotein (Apo) B ratio. However, Apo B was higher in those neonates, both male and female, with high cholesterol levels. The LDL fraction carried about 55% of TC in females with high TC levels (HF), whereas it transported just 40% in males with high TC levels (HM). LDL appeared more enriched in cholesterol than in Apo B in HF than in HM (p < 0.01). An increased level of small LDL particles should be associated with the higher triglyceride level found amongst HM. Results in LDL composition suggest that metabolic gender-related differences in infants with normal or high TC are presented at birth.     

Reliability of reported occupational history information for US coal miners, 1969-1977

For estimating reliable exposure-response relations it is necessary that random variation in both the response and the exposure variables be sufficiently small. Variability in cumulative exposures can arise from uncertainties in self-reported work histories from interviews. In most epidemiologic surveys, the information gathered from questionnaires is used without knowing the validity or reproducibility of these data. This paper investigates the reliability of occupational histories reported by the same individuals on two occasions separated by 9 years in the US National Study of Coal Workers' Pneumoconiosis and its implications on the exposure-response relation for simple coal workers' pneumoconiosis. For 480 coal miners, from whom occupational histories were obtained twice (in 1969-1971 and 1977-1981), the reliability (intraclass correlation coefficient) of the cumulative exposures generated from each work history was 87%. Logistic model fitting of simple coal workers' pneumoconiosis prevalence to the cumulative coal dust exposure produced almost identical results. After accounting for intersurvey variability in the occupational histories, the authors found that the exposure-response coefficients estimated from information reported at the surveys were attenuated by 12%. In epidemiologic studies, knowledge of the reproducibility of self-reported occupational history information is important to ascertain whether the true exposure effect is underestimated.     

Knowledge of asthma among parents of asthmatic children

The knowledge and attitude towards asthma, of parents, of 85 asthmatic children was assessed using a 17 item questionnaire. Results showed that 34.1% believed asthma to be contagious, 48.2% of the parents hesitated in referring to their child's illness as asthma. Other commonly held beliefs were that asthma is a life long illness (35.3%); food items are important precipitating factors for acute attacks (88.2%); mild exacerbations need to be treated with bronchodilators (6.3%); bronchodilators should be started at home before consulting a physician in case of an acute attack (61.2%); and cure of asthma is possible through modern drugs (30.6%) or through alternative systems of medicine (65%). Ninety one per cent of parents lacked an awareness of the side effects of anti-asthma medication. It is concluded that parental education through improved physician parent communication is necessary for enhancing the quality of care being provided to children with asthma, a fact also highlighted by the International Consensus Report on Management of Asthma.
