Living with multiple sclerosis: longitudinal changes in employment and the importance of symptom management

People with multiple sclerosis (MS) tend to have lower participation in paid employment compared to those with other chronic diseases. In two large-sample, self-report surveys of MS patients performed 4 years apart, employment rates were measured both cross-sectionally and longitudinally. The reasons for employment loss and perceived risk of future employment loss were also assessed. A total of 1,135 patients responded to the first survey, 1,329 to the second, and 667 to both. Longitudinal loss of employment was 5.4% over the 4 years 2003–2007, a period of relative national economic prosperity. By 2007, 56% of MS patients had lost employment due to MS and 64% were not in the paid labour force. Regression analysis indicated that men were more likely than women to leave their employment because of their MS, and older people were more likely than younger ones to do so. Level of occupational skill using Australian Bureau of Statistics categorisation was not predictive of maintaining or losing employment. The main reasons reported by people with MS for their loss of employment involved the ineffective management of symptoms of MS in the workplace, rather than workplace-related factors including insufficient flexibility of employment conditions or being asked to leave or sacked. The most frequently listed symptoms relating to employment loss, and perceived risk of losing current employment, were fatigue, mobility-related symptoms, arm and hand difficulties, and cognitive deficits. These findings imply that many employees with MS are leaving their planning for effective symptom management, and for appropriate accommodations in the workplace, until such planning is too late to be effective. The potential advantages of early, supported disclosure of diagnosis to employers before MS symptoms become a problem are discussed.     

pcDNA3.1tdTomato Is Superior to pDsRed2-N1 for Optical Fluorescence Imaging in the F344/AY-27 Rat Model of Bladder Cancer

Purpose  

Animal models are important for pre-clinical assessment of novel therapies in metastatic bladder cancer. The F344/AY-27 model involves orthotopic colonisation with AY-27 tumour cells which are syngeneic to F344 rats. One disadvantage of the model is the unknown status of colonisation between instillation and sacrifice. Non-invasive optical imaging using red fluorescence reporters could potentially detect tumours in situ and would also reduce the number of animals required for each experiment.     

‘Levels’ of attainment in nursing practice: reality or illusion?

In earlier research based on an analysis of course documentation, it had been found that there was little consensus among nurse educators concerning the parameters which distinguish levels of practice skills, particularly those which differentiate diploma and degree qualifications in the United Kingdom. This result was confirmed and strengthened in the current study. Lecturers in nursing, when presented with a sorting task using 40 statements derived from course documentation selected from the earlier study, were unable to distinguish statements describing diploma level from those describing degree level practice. Possible reasons for the difficulty are discussed. It is concluded that the attempt to represent practice skill in a hierarchy of assessment for degree or diploma qualifications is premature since the parameters of practice remain unreliably specified.     

Methamphetamine Residue Dermal Transfer Efficiencies from Household Surfaces

Methamphetamine contamination from illegal production operations poses a potential health concern for emergency responders, child protective services, law enforcement, and children living in contaminated structures. The objective of this study was to evaluate dermal transfer efficiencies of methamphetamine from contaminated household surfaces. These transfer efficiencies are lacking for methamphetamine, and would be beneficial for use in exposure models. Surfaces were contaminated using a simulated smoking method in a stainless steel chamber. Household surfaces were carpet, painted drywall, and linoleum. Dermal transfer efficiencies were obtained using cotton gloves for two hand conditions, dry or saliva moistened (wet). In addition, three contact scenarios were evaluated for both hand conditions: one, two, or three contacts with contaminated surfaces. Dermal transfer efficiencies were calculated for both hand conditions and used as inputs in a Stochastic Human Exposure and Dose Simulation model (SHEDS-Multimedia, Office of Research and Development, United States Environmental Protection Agency, Research Triangle Park, N.C.). Results of this study showed that average dermal transfer efficiencies of methamphetamine ranged from 11% for dry hands to 26% for wet hands. There was a significantly higher wet transfer as compared to dry transfer for all surfaces. For wet hands, dermal transfer depended on surface type with higher transfer from carpet and linoleum as compared to drywall. Based on our estimates of dermal transfer efficiency, a surface contamination clearance level of 1.5 μg/100 cm² may not ensure absorbed doses remain below the level associated with adverse health effects in all cases. Additional dermal transfer studies should be performed using skin surrogates that may better predict actual skin transfer.     

Granulomatous Uveitis and Conjunctivitis Due to Common Variable Immune Deficiency: A Case Report

Purpose: To describe a case of granulomatous anterior uveitis and histologically confirmed chronic granulomatous conjunctivitis in the presence of common variable immune deficiency (CVID).

Methods: Interventional case report.

Results: A 72-year-old female with a history of CVID treated with regular intravenous immunoglobulin (IVIG) infusions developed chronic conjunctivitis and granulomatous anterior uveitis. She responded to topical steroids, but there was recurrence upon cessation of steroid therapy. Conjunctival biopsy demonstrated micro-granulomas in the stroma and epithelium. Treatment with IVIG was maintained throughout.

Conclusion: Although rare, a diagnosis of CVID should be considered in patients with recurrent conjunctivitis and uveitis of unknown etiology, especially if there is a clinical history suggestive of defective immunity. They tend to respond well to continued steroid therapy, and IVIG therapy should not be stopped.
