Conversion of an administrative record system for compatibility with the ICIDH.

This paper presents an account of considerations relevant to conversion of data in an administrative record system into categories compatible with the ICIDH. Existing information recorded for the Swiss disablement insurance scheme fairly readily generates impairment and disability data relating to the time of first contact with the scheme, and the means for conversion are illustrated. The system does not generate data relevant to handicap.

Traitement chronique de l'hypertension arterielle par un inhibiteur de l'enzyme de conversion de l'angiotensine. [Chronic treatment of hypertension by an inhibitor of angiotensin converting enzyme]

Captopril, or SQ 14,225 an orally active inhibitor of angiotensin-converting enzyme, produced a significant blood pressure reduction in 26 hypertensives. This new drug, alone or combined with a diuretic, has normalized the blood pressure of the 22 patients on long-term treatment.

Forgoing dental care for economic reasons in Switzerland: a six-year cross-sectional population-based study

BACKGROUND: While oral health is part of general health and well-being, oral health disparities nevertheless persist. Potential mechanisms include socioeconomic factors that may influence access to dental care in the absence of universal dental care insurance coverage. We investigated the evolution, prevalence and determinants (including socioeconomic) of forgoing of dental care for economic reasons in a Swiss region, over the course of six years. METHODS: Repeated population-based surveys (2007-2012) of a representative sample of the adult population of the Canton of Geneva, Switzerland. Forgone dental care, socioeconomic and insurance status, marital status, and presence of dependent children were assessed using standardized methods. RESULTS: A total of 4313 subjects were included, 10.6% (457/4313) of whom reported having forgone dental care for economic reasons in the previous 12 months. The crude percentage varied from 2.4% in the wealthiest group (monthly income ≥ 13,000 CHF, 1 CHF ≈ 1$) to 23.5% among participants with the lowest income (<3,000 CHF). Since 2007/8, forgoing dental care remained stable overall, but in subjects with a monthly income of <3,000 CHF, the adjusted percentage increased from 16.3% in 2007/8 to 20.6% in 2012 (P trend = 0.002). Forgoing dental care for economic reasons was independently associated with lower income, younger age, female gender, current smoking, having dependent children, divorced status and not living with a partner, not having a supplementary health insurance, and receipt of a health insurance premium cost-subsidy. CONCLUSIONS: In a Swiss region without universal dental care insurance coverage, prevalence of forgoing dental care for economic reasons was high and highly dependent on income. Efforts should be made to prevent high-risk populations from forgoing dental care.

The estrogen-responsive element as an inducible enhancer: DNA sequence requirements and conversion to a glucocorticoid-responsive element.

The estrogen-responsive element (ERE) present in the 5'-flanking region of the Xenopus laevis vitellogenin (vit) gene B1 has been characterized by transient expression analysis of chimeric vit-tk-CAT (chloramphenicol acetyltransferase) gene constructs transfected into the human estrogen-responsive MCF-7 cell line. The vit B1 ERE behaves like an inducible enhancer, since it is able to confer estrogen inducibility to the heterologous HSV thymidine kinase (tk) promoter in a relative position- and orientation-independent manner. In this assay, the minimal B1 ERE is 33 bp long and consists of two 13 bp imperfect palindromic elements both of which are required for the enhancer activity. A third imperfect palindromic element is present further upstream within the 5'-flanking region of the gene but is unable to confer hormone responsiveness by itself. Similarly, neither element forming the B1 ERE can alone confer estrogen inducibility to the tk promoter. However, in combinations of two, all three imperfect palindromes can act cooperatively to form a functional ERE. In contrast a single 13 bp perfect palindromic element, GGTCACTGTGACC, such as the one found upstream of the vit gene A2, is itself sufficient to act as a fully active ERE. Single point mutations within this element abolish estrogen inducibility, while a defined combination of two mutations converts this ERE into a glucocorticoid-responsive element.

Hippocampal atrophy predicts conversion to dementia after STN-DBS in Parkinson's disease.

BACKGROUND: Hippocampal atrophy (HA) is a known predictor of dementia in Alzheimer's disease. HA has been found in advanced Parkinson's disease (PD), but no predicting value has been demonstrated yet. The identification of such a predictor in candidates for subthalamic deep brain stimulation (STN-DBS) would be of value. Our objective was to compare preoperative hippocampal volumes (HV) between PD patients who subsequently converted to dementia (PDD) after STN-DBS and those who did not (PDnD). METHODS: From a cohort of 70 consecutive STN-DBS treated PD patients, 14 converted to dementia over 25.6+/-20.2 months (PDD). They were compared to 14 matched controls (PDnD) who did not convert to dementia after 43.9+/-11.7 months. On the preoperative 3D MPRAGE MRI images, HV and total brain volumes (TBV) were measured by a blinded investigator using manual and automatic segmentation respectively. RESULTS: PDD had smaller preoperative HV than PDnD (1.95+/-0.29 ml; 2.28+/-0.33 ml; p<0.01). This difference reinforced after normalization for TBV (3.28+/-0.48, 3.93+/-0.60; p<0.01). Every 0.1 ml decrease of HV increased the likelihood to develop dementia by 24.6%. A large overlap was found between PD and PDnD HVs, precluding the identification of a cut-off score. CONCLUSIONS: As in Alzheimer's disease, HA may be a predictor of the conversion to dementia in PD. This preoperative predictor suggests that the development of dementia after STN-DBS is related to the disease progression, rather then the procedure. Further studies are needed to define a cut-off score for HA, in order to affine its predictive value for an individual patient.

What's so special about conversion disorder? A problem and a proposal for diagnostic classification.

Conversion disorder presents a problem for the revisions of DSM-IV and ICD-10, for reasons that are informative about the difficulties of psychiatric classification more generally. Giving up criteria based on psychological aetiology may be a painful sacrifice but it is still the right thing to do.
