### Multiple sclerosis, an unlikely cause of chronic cerebrospinal ...

by temum01 0 Comments 19 Viewed 0 Times

Objectives It is unknown if a relationship exists between multiple sclerosis and chronic cerebrospinal venous insufﬁciency and if this venous pathology is a causal factor for multiple sclerosis or is a product of a neurological disease. Even so, one should expect that if multiple sclerosis were the cause for venous lesions, then patients with an extended history of the disease would present with a more severe venous pathology. Design Retrospective analysis of catheter venography of the azygous and internal jugular veins, and duration of clinical history of the disease in multiple sclerosis patients. Regional Silesian Board of Physicians in Katowice, Poland (approval number 7/ 2010). The study has been registered at ClinicalTrials.gov, identiﬁer NCT01264848 Guarantor MS Contributorship All authors contributed equally Acknowledgements None Reviewer Ali Yagan Setting Mono-proﬁle specialist hospital. Participants 353 multiple sclerosis patients, with duration of the disease: 0.5-41 years (median: 10 years). Main outcome measures We performed statistical analysis of the correlations between the duration of multiple sclerosis and the degree and number of venous lesions revealed using catheter venography. Results We observed weak, statistically insigniﬁcant correlations between the severity of chronic cerebrospinal venous insufﬁciency and the duration of multiple sclerosis. For the cumulated scores of venous lesions, Spearman and Kendall’s tau correlation coefﬁcients were 0.03 and 0.02, respectively; for maximal scores of venous lesions, coefﬁcients were 0.06 and 0.05, while for the number of diseased veins they were 0.007 and 0.006, respectively. Consequently, this analysis did not yield any data supporting the idea that MS is the cause of venous lesions. Conclusion The results of our survey indicated that venous malformations are most likely congenital, and multiple sclerosis had no...

### Hairdressing Environmental Scan 2013 - Retail and Personal ...

by james 0 Comments 14 Viewed 0 Times

The Hairdressing Industry is captured in the Australian and New Zealand Standard Industrial Classification (ANZSIC) under Group 951 ‘Personal Care Services’ in class 9511 ‘Hairdressing and Beauty Services’ 1. The Hairdressing Industry in Australia is predominantly made up of small and medium enterprises, most employing between four and six people of whom a high share are apprentices. While the majority of businesses are owner operated there are some chains, including franchises. Most businesses are Australian owned with limited international ownership. Competition is high and will remain high as a large number of salons compete for clients. Enterprises which employ less than 20 people account for an estimated 96.8% of businesses, 90% of industry employment and 86% of total revenue. It is anticipated that the hairdressing and beauty industry will generate revenue of \$4 billion in 2012–13, representing real growth of 2.0%, compared with the previous year. 2 In November 2011, 55,200 people were employed in the Hairdressing Industry, of which 85% were female and 60% part time employees. 3 The median age for employees in hairdressing is currently 32 years of age and 20.7% are aged 45 years and over (compared with 35.2% for all occupations). 4 Hairdressing is currently the largest employing occupation in the personal services sector and the largest employer of females in trades.

### Treatment of Metastatic Prostatic Cancer With Low-Dose Prednisone ...

Treatment of Metastatic Prostatic Cancer With Low-Dose Prednisone: Evaluation of Pain and Quality of Life as Pragmatic Indices of Response By lan Tannock, Mary Gospodarowicz, William Meakin, Tony Panzarella, Lesley Stewart, and Walter Rider Thirty-seven men with symptomatic bone metastases from prostate cancer that had progressed following earlier treatment with estrogens and/or orchidectomy were treated with low-dose prednisone (7.5 to 10 mg daily). The rationale for this treatment was that some patients might still have hormone-sensitive disease that was stimulated by weak androgens of adrenal origin, and that these androgens could be suppressed by prednisone through its negative feedback on secretion of adrenocorticotrophic hormone (ACTH). Response to treatment was assessed by requirement for analgesics, by the McGill-Melzack pain questionnaire, and by a series of 17 linear analog selfassessment (LASA) scales relating to pain and to various aspects of quality of life. Fourteen patients (38%) had improvement in indices used to assess pain at 1 month after starting prednisone, and seven patients (19%) maintained this improvement for 3 to 30 months (median, 4 months). Reduction in pain was...
