Kyste epidermoide intracranien

Introduction: Aim : To evaluate the value of magnetic resonance imaging (MRI) in the diagnosis of 2 cases of epidermoid cysts.Materieal and Methods: 2 cases of histopathologically proven epidermoid cysts were studied. All patients were examined with conventional MRI (T1WI, T2WI, FLAIR) and Diffusion-weighted imaging (DWI).Results: the lesions were located in the right cerebellopontine angle and the right temporal fossa. All lesions were hyperintense on T2, hypointense on T1and strikingly hyperintense on DW.Conclusion: New MR techniques such as FLAIR and DWI are most helpful tools in the specific preoperative diagnosis which is important for surgical guidance

The Neurotensin Receptor-1 Pathway Contributes to Human Ductal Breast Cancer Progression

BACKGROUND: The neurotensin (NTS) and its specific high affinity G protein coupled receptor, the NT1 receptor (NTSR1), are considered to be a good candidate for one of the factors implicated in neoplastic progression. In breast cancer cells, functionally expressed NT1 receptor coordinates a series of transforming functions including cellular migration and invasion. METHODS AND RESULTS: we investigated the expression of NTS and NTSR1 in normal human breast tissue and in invasive ductal breast carcinomas (IDCs) by immunohistochemistry and RT-PCR. NTS is expressed and up-regulated by estrogen in normal epithelial breast cells. NTS is also found expressed in the ductal and invasive components of IDCs. The high expression of NTSR1 is associated with the SBR grade, the size of the tumor, and the number of metastatic lymph nodes. Furthermore, the NTSR1 high expression is an independent factor of prognosis associated with the death of patients. CONCLUSION: these data support the activation of neurotensinergic deleterious pathways in breast cancer progression

Patient risk profiles and practice variation in nonadherence to antidepressants, antihypertensives and oral hypoglycemics

BACKGROUND: Many patients experience difficulties in following treatment recommendations. This study's objective is to identify nonadherence risk profiles regarding medication (antidepressants, antihypertensives, and oral hypoglycemics) from a combination of patients' socio-demographic characteristics, morbidity presented within general practice and medication characteristics. An additional objective is to explore differences in nonadherence among patients from different general practices. METHODS: Data were obtained by linkage of a Dutch general practice registration database to a dispensing registration database from the year 2001. Subjects included in the analyses were users of antidepressants (n = 4,877), antihypertensives (n = 14,219), or oral hypoglycemics (n = 2,428) and their GPs. Outcome variables were: 1) early dropout i.e., a maximum of two prescriptions and 2) refill nonadherence (in patients with 3+ prescriptions); refill adherence < 80% was considered as nonadherence. Multilevel modeling was used for analyses. RESULTS: Both early dropout and refill nonadherence were highest for antidepressants, followed by antihypertensives. Risk factors appeared medication specific and included: 1) non-western immigrants being more vulnerable for nonadherence to antihypertensives and antidepressants; 2) type of medication influencing nonadherence in both antihypertensives and antidepressants, 3) GP consultations contributing positively to adherence to antihypertensives and 4) somatic co-morbidity influencing adherence to antidepressants negatively. There was a considerable range between general practices in the proportion of patients who were nonadherent. CONCLUSION: No clear risk profiles for nonadherence could be constructed. Characteristics that are correlated with nonadherence vary across different types of medication. Moreover, both patient and prescriber influence adherence. Especially non-western immigrants need more attention with regard to nonadherence, for example by better monitoring or communication. Since it is not clear which prescriber characteristics influence adherence levels of their patients, there is need for further research into the role of the prescriber

Measuring performance on the Healthcare Access and Quality Index for 195 countries and territories and selected subnational locations: A systematic analysis from the Global Burden of Disease Study 2016

Background: A key component of achieving universal health coverage is ensuring that all populations have access to quality health care. Examining where gains have occurred or progress has faltered across and within countries is crucial to guiding decisions and strategies for future improvement. We used the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) to assess personal health-care access and quality with the Healthcare Access and Quality (HAQ) Index for 195 countries and territories, as well as subnational locations in seven countries, from 1990 to 2016. Methods Drawing from established methods and updated estimates from GBD 2016, we used 32 causes from which death should not occur in the presence of effective care to approximate personal health-care access and quality by location and over time. To better isolate potential effects of personal health-care access and quality from underlying risk factor patterns, we risk-standardised cause-specific deaths due to non-cancers by location-year, replacing the local joint exposure of environmental and behavioural risks with the global level of exposure. Supported by the expansion of cancer registry data in GBD 2016, we used mortality-to-incidence ratios for cancers instead of risk-standardised death rates to provide a stronger signal of the effects of personal health care and access on cancer survival. We transformed each cause to a scale of 0-100, with 0 as the first percentile (worst) observed between 1990 and 2016, and 100 as the 99th percentile (best); we set these thresholds at the country level, and then applied them to subnational locations. We applied a principal components analysis to construct the HAQ Index using all scaled cause values, providing an overall score of 0-100 of personal health-care access and quality by location over time. We then compared HAQ Index levels and trends by quintiles on the Socio-demographic Index (SDI), a summary measure of overall development. As derived from the broader GBD study and other data sources, we examined relationships between national HAQ Index scores and potential correlates of performance, such as total health spending per capita. Findings In 2016, HAQ Index performance spanned from a high of 97\ub71 (95% UI 95\ub78-98\ub71) in Iceland, followed by 96\ub76 (94\ub79-97\ub79) in Norway and 96\ub71 (94\ub75-97\ub73) in the Netherlands, to values as low as 18\ub76 (13\ub71-24\ub74) in the Central African Republic, 19\ub70 (14\ub73-23\ub77) in Somalia, and 23\ub74 (20\ub72-26\ub78) in Guinea-Bissau. The pace of progress achieved between 1990 and 2016 varied, with markedly faster improvements occurring between 2000 and 2016 for many countries in sub-Saharan Africa and southeast Asia, whereas several countries in Latin America and elsewhere saw progress stagnate after experiencing considerable advances in the HAQ Index between 1990 and 2000. Striking subnational disparities emerged in personal health-care access and quality, with China and India having particularly large gaps between locations with the highest and lowest scores in 2016. In China, performance ranged from 91\ub75 (89\ub71-93\ub76) in Beijing to 48\ub70 (43\ub74-53\ub72) in Tibet (a 43\ub75-point difference), while India saw a 30\ub78-point disparity, from 64\ub78 (59\ub76-68\ub78) in Goa to 34\ub70 (30\ub73-38\ub71) in Assam. Japan recorded the smallest range in subnational HAQ performance in 2016 (a 4\ub78-point difference), whereas differences between subnational locations with the highest and lowest HAQ Index values were more than two times as high for the USA and three times as high for England. State-level gaps in the HAQ Index in Mexico somewhat narrowed from 1990 to 2016 (from a 20\ub79-point to 17\ub70-point difference), whereas in Brazil, disparities slightly increased across states during this time (a 17\ub72-point to 20\ub74-point difference). Performance on the HAQ Index showed strong linkages to overall development, with high and high-middle SDI countries generally having higher scores and faster gains for non-communicable diseases. Nonetheless, countries across the development spectrum saw substantial gains in some key health service areas from 2000 to 2016, most notably vaccine-preventable diseases. Overall, national performance on the HAQ Index was positively associated with higher levels of total health spending per capita, as well as health systems inputs, but these relationships were quite heterogeneous, particularly among low-to-middle SDI countries. Interpretation GBD 2016 provides a more detailed understanding of past success and current challenges in improving personal health-care access and quality worldwide. Despite substantial gains since 2000, many low-SDI and middle- SDI countries face considerable challenges unless heightened policy action and investments focus on advancing access to and quality of health care across key health services, especially non-communicable diseases. Stagnating or minimal improvements experienced by several low-middle to high-middle SDI countries could reflect the complexities of re-orienting both primary and secondary health-care services beyond the more limited foci of the Millennium Development Goals. Alongside initiatives to strengthen public health programmes, the pursuit of universal health coverage hinges upon improving both access and quality worldwide, and thus requires adopting a more comprehensive view-and subsequent provision-of quality health care for all populations

The effect of pharmaceutical marketing on the prescription of rofecoxib in Dutch general practice.

Background: In 2000 the new painkiller rofecoxib was introduced in the Netherlands as an alternative for NSAIDs. It was extensively marketed by the pharmaceutical industry stressing its gastro protective qualities and significant pain reduction. Rofecoxib vastly obtained a significant market share. However, GPs differed considerably in the adoption of this new drug. Aim: To study the effect of the use of information of the pharmaceutical industry on the prescription of the new drug rofecoxib in Dutch general practice. Methods: Data from the Second Dutch National Survey of General Practice (DNSGP-2) were used.During this representative survey of morbidity in 104 Dutch general practices (comprising of 195 GP’s who served 385.461 patients) in 2001 all contacts with patients were registered. Additional data were collected on all GP’s of DNSGP-2, they filled in a detailed questionnaire. GP questionnaire were linked to prescription data from the GP’s registrations. Data were analysed using multilevel analysis to take into account the clustering of rofecoxib prescriptions within GP’s. Outcome variables were number of rofecoxib prescriptions and number of NSAID prescriptions within the year of registration. Results: Preliminary analyses show that prescriptions of rofecoxib rapidly increased in the first year of introduction in 2000. After the first year of introduction rofecoxib prescriptions still increases but more steadily. Both patient and GP characteristics influence the volume of the prescription of rofecoxib. The most influencing factor at the GP level is the number of visits of drug representatives the GP had: the more visits the more rofecoxib the GP prescribed. Moreover, the more written information the GP used (such as information of the pharmaceutical industry), the more rofecoxib was prescribed. GPs who used national or regional professional guidelines more often, prescribed less rofecoxib. Conclusions: Information of the pharmaceutical industry is an important factor in stimulating the prescription of the new drug rofecoxib. Implications of this finding will be discussed at the conference

Afschaffen vergoeding zelfzorggeneesmiddelen: uitzonderingen denkbaar?

Ruim 13% van de Nederlandse bevolking, ofwel 2,2 miljoen inwoners, krijgt een zelfzorggeneesmiddel voorgeschreven door hun huisarts. Nadat VWS op 1 januari 2004 de vergoeding hiervoor afschafte, kostte hen dat volgens berekeningen van het NIVEL gemiddeld 31 euro per persoon per jaar. Veel mensen betaalden echter fors meer dan dat gemiddelde. Ruim 35.000 mensen waren meer dan 250 euro per jaar kwijt aan zelfzorggeneesmiddelen op doktersvoorschrift. Dit blijkt uit NIVEL onderzoek in opdracht van het Ministerie van VWS naar het gebruik en de kosten van zelfzorggeneesmiddelen. Per 1 januari 2004 is de vergoeding voor zelfzorggeneesmiddelen voor iedereen komen te vervallen. Doel van het NIVEL onderzoek was het aanwijzen van groepen mensen (bijvoorbeeld ouderen, vrouwen, mensen met een bepaalde ziekte of mensen die een bepaald type geneesmiddel gebruikten) die onevenredig hoge kosten maakten voor hun zelfzorggeneesmiddelen. Voor hen zou dan een groepsgewijze uitzondering gemaakt kunnen worden wat betreft het afschaffen van de vergoeding. Dit bleek echter onmogelijk, want de mensen die hoge kosten hadden waren qua leeftijd, ziektebeeld of medicatiegebruik niet te onderscheiden van mensen die minder kosten maken. Bepaalde groepen (zoals bijvoorbeeld Parkinson patiënten) uitzonderen zou teveel anderen, met óók hoge kosten, tekort doen. Wel bleek een aantal zelfzorggeneesmiddelen erg duur te zijn. Mede naar aanleiding van dit NIVEL onderzoek heeft het Ministerie van VWS deze bezuinigingsmaatregel deels teruggedraaid. Mensen die langer dan zes maanden op doktersvoorschrift een van de onderstaande vijf soorten dure zelfzorggeneesmiddelen gebruiken, krijgen deze vergoed van hun verzekeraar. Het gaat om laxeermiddelen, middelen tegen diarree, kalktabletten, anti-allergiemiddelen, en middelen bij maagledigingsstoornissen

Visie van de huisarts op de samenwerking met bedrijfsartsen anno 2003 nog onveranderd.

De laatste jaren zijn er veel initiatieven ondernomen om de samenwerking tussen huisartsen en bedrijfsartsen bij de begeleiding en behandeling van zieke werknemers te verbeteren. Onderzocht is of dit gepaard is gegaan met veranderingen in de visie van huisartsen op deze samenwerking. Hiertoe zijn gegevens verzameld middels een schriftelijke vragenlijst die is verstuurd naar alle huisartsen in het Landelijk Informatie Netwerk Huisartsen (LINH), als deel van de jaarlijkse enquête in 2001 en 2003. Er zijn weinig verschillen gevonden tussen deze twee metingen. Huisartsen ondrvinden nog steeds praktische knelpunten bij het leggen van contact en samenwerking met bedrijfsartsen is geen dagelijks terugkerende activiteit in de huisartspraktijk (minder dan twee contacten per maand). De meeste huisartsen zijn wel goed te spreken over de contacten met bedrijfsartsen. Geconcludeerd wordt dat de toenemende aandacht voor de samenwerking tussen huisartsen en bedrijfsartsen in de periode 2001-2003 geen noemenswaardige invloed lijkt te hebben gehad op hoe huisartsen tegen deze samenwerking aankijken.
