Longitudinal associations between television in the bedroom and body fatness in a UK cohort study.

OBJECTIVE: To assess longitudinal associations between screen-based media use (television (TV) and computer hours, having a TV in the bedroom) and body fatness among UK children. METHODS: Participants were 12 556 children from the UK Millennium Cohort Study who were followed from age 7 to age 11 years. Associations were assessed between screen-based media use and the following outcomes: body mass index (BMI), fat mass index (FMI), and overweight. RESULTS: In fully adjusted models, having a bedroom TV at age 7 years was associated with significantly higher BMI and FMI (excess BMI for boys=0.29, 95% confidence interval (CI) 0.06-0.52; excess BMI for girls=0.57, 95% CI 0.31-0.84; excess FMI for boys=0.20, 95% CI 0.04-0.37; excess FMI for girls=0.39, 95% CI 0.21-0.57) and increased risk of being overweight (relative risk (RR) for boys=1.21, 95% CI 1.07-1.36; RR for girls=1.31, 95% CI 1.15-1.48) at age 11 years, compared with having no bedroom TV. Hours spent watching TV or digital versatile disks were associated with increased risk of overweight among girls only. Computer use at age 7 years was not related to later body fatness for either gender. CONCLUSION: Having a TV in the child's bedroom was an independent risk factor for overweight and increased body fatness in this nationally representative sample of UK children. Childhood obesity prevention strategies should consider TVs in children's bedrooms as a risk factor for obesity.

Social inequalities in clustering of oral health related behaviors in a national sample of British adults.

OBJECTIVES: 1. To assess clustering of oral health related behaviors among a sample of British adults. 2. To determine the variation in clustering of oral health related behaviors by socioeconomic position. METHOD: We used secondary analysis of the Adult Dental Health Survey 2009 data. Health behaviors referred to smoking, tooth brushing frequency, dental visits and sugar consumption. Clustering was assessed by pairwise correlations, counts of clustering of health compromising behaviors and comparison of observed/expected ratios. Logistic regression was used to assess variation in clustering of oral health related behaviors by socioeconomic position crudely and adjusted for age, gender and self-rated oral health. RESULTS: There were weak correlations between four health behaviors. Very low prevalence of clustering was reported. Higher observed to expected ratio was observed for clustering patterns with lower prevalence. Multivariate logistic regression showed clear, strong and significant educational gradients in associations between different clustering patterns of health compromising behaviors and educational attainment. These educational gradients remained significant after adjusting for age, gender and self-reported oral health. CONCLUSION: Very clear and strong educational gradients were observed throughout patterns of clustering of oral health compromising behaviors, suggesting chances of having detrimental behavioral clustering are lower in more educated groups in population.

[Disputable thoracic pain with normal coronary arteries. Metabolic study]. / Douleurs thoraciques litigieuses à coronaires saines Etude métabolique

The search for electrocardiographic, haemodynamic and above an metabolic criteria suggestive of "myocardial ischaemia" in the course of an atrial pacing test was found to be positive in three patients suffering from atypical thoracic pains, and in whom selective coronary arteriograms might be considered as normal. It appaear thus that the criterion of a normal coronary arteriography and a negative or unsignificant effort test is insufficient to discard the diagnosis of "myocardial ischaemia" when confronted with such pains habitually considered as anorganic. The accurate mechanism of these pains, probably identical to that or those of "angina with normal coronary arteriography" remains undecided.

[Mitral stenosis and partial abnormal pulmonary venous return. 3 case reports]. / Rétrécissement mitral et retour veineux pulmonaire anormal partiel. Apropos de trois observations

The association of mitral stenosis with an abnormal pulmonary venous return in the absence of an atrial septal defect, is a rare occurrence, and three cases are reported here. If this diagnosis is suggested by the chest Xray, it is confirmed by haemodynamic investigation, which defines the abnormal pulmonary drainage, guages the size of the left-right shunt, and demonstrates the degree of mitral steonsis. If the defect is poorly tolerated, surgical treatment is required.

[Coronary insufficiency in pheochromocytoma]. / L'insuffisance coronarienne des phéochromocytomes

The authors report the case of a 42 year old female with a phaeochromocytoma who, in the course of a hypertensive episode, had ECG changes typical of a myocardial infarction. These changes regressed within a few days. A normal coronary arteriogram confirmed the purely functional nature of this episode of acute myocardial ischaemia. In addition to the case report, the authors discuss the physio-pathological and electrocardiographic features of the coronary insufficiency of phaeochromocytoma, and also the problem of the rapide regression of the changes of infarction on the ECG.

Oral health of female prisoners in HMP Holloway: implications for oral health promotion in UK prisons.

OBJECTIVES: This study describes the oral health status and associated risk factors in a sample of female prisoners and compares their oral health to that of the female population from the 2009 Adult Dental Health Survey. METHOD: A random sample of prisoners was selected from HMP Holloway, London. Structured interviews were carried out to collect information on oral health behaviours and oral health related quality of life. Clinical examinations using the Adult Dental Health Survey criteria assessed the oral health needs of prisoners. RESULTS: The mean age of female prisoners (n = 103) was 30.9 ± 9.6 years. The prevalence of oral diseases was high. Seventy-five percent had decayed or unsound teeth. The mean DMFT was 12.3 ± 7.5. Compared to the general female population, prisoners had more decayed and fewer filled teeth. Sixty-six percent had periodontal pockets of 4 mm or more. A large proportion (73%) reported at least one oral impact on daily performances. Prisoners were more likely than the general female population to engage in oral health damaging behaviours such as high sugar intake and smoking. CONCLUSION: This survey has demonstrated the poor state of oral health and identified considerable levels of unmet dental treatment needs in HMP Holloway. Urgent action is required to address this major public health problem.
