Background: In recent randomized controlled trials (RCTs) intra-arterial treatment (IAT) has been proven effective and safe for patients with acute ischemic stroke (AIS). So far, there seemed to be no interaction between older age (>80) and main treatment effect. We studied the association of older age with outcome and adverse events after IAT in a cohort of intra arterially treated patients. Methods and findings: Data from all AIS patients with proven proximal anterior circulation cerebral artery occlusion who were intra arterially treated between 2002 until the start of the MR CLEAN trial were studied retrospectively. Duration of the procedure, recanalization (Thrombolysis In Cerebral Infarction score (TICI)), early neurological recovery (i.e. decrease on NIHSS of ≥ 8 points) after one week or at discharge, good functional outcome at discharge by modified Rankin Scale (mRS ≤ 2) and the occurrence of neurological and non-neurological adverse events were assessed and the association with age was investigated. In total 315 patients met our inclusion criteria. Median age was 63 years (range 22-93) and 17 patients (5.4 %) were over 80. Age was inversely associated with good functional outcome (adjusted Odds Ratio (aOR) 0.80, 95 % CI: 0.66-0.98) for every 10 years increase of age. Age was not associated with longer duration of the procedure, lower recanalization rate or less early neurological recovery. The risk of all adverse events (aOR 1.27; 95 % CI: 1.08-1.50) and non-neurological adverse events (aOR 1.34; 95 % CI: 1.11-1.61) increased, but that of peri-procedural adverse events (aOR 0.79; 95 % CI: 0.66-0.94) decreased with age. Conclusion: Higher age is inversely associated with good functional outcome after IAT in patients with AIS. However, treatment related adverse events are not related to age. These findings may help decision making when considering treatment of older patients with AIS. © 2016 Beumer et al. Source

Case Reports in Ophthalmology | Year: 2012

We report the case of a 54-year-old female who was referred to us with an amelanotic mass on the posterior pole of the left eye involving the macula. Fundus fluorescein angiography revealed a hyperfluorescent choroidal mass. Indocyanine green chorioangiography revealed a hypofluorescent choroidal lesion with hyperfluorescent margins. B-scan ultrasonography showed a choroidal mass with moderate reflectivity. Choroidal biopsy was performed, which revealed the diagnosis of Fuchs' adenoma. Copyright © 2012 S. Karger AG, Basel.

Background and purpose: Sprengel's deformity, a rare congenital malformation of the scapula, may be observed in combination with spinal dysraphism. The co-occurrence of these malformations suggests an unknown shared etiology. Therefore, we reviewed the medical records of eight children presenting with both malformations and performed a review of the literature. Patients and methods: Databases from four university medical centers were searched for children presenting between 1992 and 2012 with spinal dysraphism and a Sprengel's deformity. Conclusion: The combination of spinal dysraphism and Sprengel's deformity is rare, and is associated with segmentation defects of the spine and ribs. Although the etiology of both spinal dysraphism and Sprengel's deformity remains unclear, all deformities of the spine, ribs, and shoulder might result from a common genetic defect affecting somitogenesis. © 2013 Springer-Verlag Berlin Heidelberg.

Background: To make proper evaluation of prevention policies possible, data on the incidence and associated medical costs of occupational blood exposure accidents in the Netherlands are needed. Methods: Descriptive analysis of blood exposure accidents and risk estimates for occupational groups. Costs of handling accidents were calculated. Results: Each year, an estimated 13 000-15 000 blood exposure accidents are reported in the Netherlands, 95 in occupational settings. Hepatitis B (HBV) vaccination is offered free of charge only to people in risk groups, the seroprevalence of HBV, hepatitis C (HCV) and human immunodeficiency virus (HIV) is low and few infections are related to blood exposure accidents. High-risk accidents occur mainly in hospitals. In nursing homes and home care settings, the majority of the accidents are low-risk. Limited data are available about occurrence of accidents in other occupational groups. Associated medical costs from occupational blood exposure accidents are mainly determined by the initial risk management. Conclusions: Accidents must be managed effectively to prevent infection and reduce anxiety in injured employees. While strategies to reduce HCV and HIV infection should be primarily aimed at reducing the occurrence of high-risk accidents, vaccination can prevent HBV infection and cut the costs of handling low-risk accidents. The implementation of vaccination strategies, safe working policies and the proper use of safe equipment should be monitored better. © 2009 The Author.

Context: The evidence that measurement of the common carotid intima-media thickness (CIMT) improves the risk scores in prediction of the absolute risk of cardiovascular events is inconsistent. Objective: To determine whether common CIMT has added value in 10-year risk prediction of first-time myocardial infarctions or strokes, above that of the Framingham Risk Score. Data Sources: Relevant studies were identified through literature searches of databases (PubMed from 1950 to June 2012 and EMBASE from 1980 to June 2012) and expert opinion. Study Selection: Studies were included if participants were drawn from the general population, common CIMT was measured at baseline, and individuals were followed up for first-time myocardial infarction or stroke. Data Extraction: Individual data were combined into 1 data set and an individual participant data meta-analysis was performed on individuals without existing cardiovascular disease. Results: We included 14 population-based cohorts contributing data for 45 828 individuals. During a median follow-up of 11 years, 4007 first-time myocardial infarctions or strokes occurred. We first refitted the risk factors of the Framingham Risk Score and then extended the model with common CIMT measurements to estimate the absolute 10-year risks to develop a first-time myocardial infarction or stroke in both models. The C statistic of both models was similar (0.757; 95% CI, 0.749-0.764; and 0.759; 95% CI, 0.752-0.766). The net reclassification improvement with the addition of common CIMT was small (0.8%; 95% CI, 0.1%-1.6%). In those at intermediate risk, the net reclassification improvement was 3.6% in all individuals (95% CI, 2.7%-4.6%) and no differences between men and women. Conclusion: The addition of common CIMT measurements to the Framingham Risk Score was associated with small improvement in 10-year risk prediction of first-time myocardial infarction or stroke, but this improvement is unlikely to be of clinical importance. ©2012 American Medical Association.
