A 28-year-old woman was referred to our department with a syncopalsustained ventricular tachycardia with right bundle branch morphology.She was diagnosed with a pericarditis when she was 2 years old,and related an episode of palpitations     

Goal satisfaction improves with individualized powered wheelchair skills training

Purpose: To determine improvements in goal satisfaction following individualized mobility-related powered wheelchair skills training and whether changes in satisfaction are maintained 3 months post-training.

Materials and methods: Seventeen powered wheelchair users, from two centres, who were randomized to the training intervention from a larger multicentre study, were included in this secondary analysis. The intervention consisted of five 30-min individualized Wheelchair Skills Training Program sessions. Participants rated their current satisfaction with each of their goals from 0 to 10 (10 being the highest) prior to training, immediately after the intervention, and approximately 3 months following the intervention. Themes relating to the participants’ goals were also explored.

Results: Goal satisfaction scores improved statistically (p?r?=?0.387, n?=?17, p?=?.125). The majority of goals set fell into the broader “manoeuvring” category.

Conclusion: Goal satisfaction following the Wheelchair Skills Training Program improved years after initially learning how to operate a powered wheelchair. The five training sessions were effective in improving goal satisfaction. The quantification of goal satisfaction appears to be a sensitive outcome for powered wheelchair users undergoing mobility-related training.

• Implications for rehabilitation

• Goal satisfaction improved following the Wheelchair Skills Training Program.

• Even with years of powered wheelchair experience, the majority of goals set fell into the broader “manoeuvring” category.

• An individual’s goal satisfaction may not correlate with whether they have attained their goal as determined by a trainer.

     

Effects of controlled whole-body vibration training in improving fall risk factors among individuals with multiple sclerosis: A pilot study

Purpose: The purpose of this study was to systematically examine the effect of an 8-week controlled whole-body vibration training on improving fall risk factors and the bone mineral density among people with multiple sclerosis (PwMS).

Methods: This study adopted a single group pre-test–post-test design. Twenty-five PwMS (50.3 years SD 14.1) received vibration training on a side-alternating vibration platform. Each training session was repeated three times every week for 8 weeks. Prior to and following the 8-week training course, a battery of fall risk factors were evaluated: the body balance, functional mobility, muscle strength, range of motion, and fear of falling. Bone density at both calcanei was also assessed.

Results: Twenty-two participants completed the study. Compared with pre-test, almost all fall risk factors and the bone density measurement were significantly improved at post-test, with moderate to large effect sizes varying between 0.571 and 1.007.

Conclusions: The 8-week vibration training was well accepted by PwMS and improved their fall risk factors. The important findings of this study were that vibration training may increase the range of motion of ankle joints on the sagittal plane, lower the fear of falling, and improve bone density.

• IMPLICATIONS FOR REHABILITATION

• An 8-week vibration training course could be well-accepted by people with multiple sclerosis (MS).

• Vibration training improves the risk factors of falls in people living with MS.

• Vibration training could be a promising rehabilitation intervention in individuals with MS.

Efficacy of topical diclofenac diethylamine gel in osteoarthritis of the knee

OBJECTIVE: To assess the efficacy and safety of topical diclofenac diethylamine gel, 1.16%, 4 g applied qid for 3 weeks to relieve the symptoms of osteoarthritis (OA) of the knee. METHODS: Patients with OA of the knee washed out their OA medications for at least 5 drug half-lives. Patients with adequately high baseline pain scores were randomized to apply either double-blind active or placebo gel for 3 weeks. Acetaminophen (up to 2 g/day) was supplied as rescue medication. In a diary, patients recorded compliance to dosing and use of rescue medication and assessed daily pain on movement, spontaneous pain, and pain relief. At weekly site visits, patients completed the Western Ontario and McMaster (WOMAC) Osteoarthritis Index Questionnaire, which includes assessment of pain, stiffness, and physical function, and assessed pain intensity "right now." At the final visit, a global assessment of treatment efficacy was completed. RESULTS: Of 238 randomized patients, 237 were included in the intent to treat efficacy analysis. Treatments differed significantly for daily pain on movement at Day 5, and continued on most days through end of study. Peak differences were achieved in the second week. On the primary outcome, average pain on movement over Days 1-14, diclofenac gel was significantly superior to placebo gel. Scores for all 3 WOMAC indices for diclofenac gel treatment were significantly superior to placebo at Weeks 2 and 3. A significant difference was achieved on pain intensity "right now" at all 3 weeks. At the end of the study, patients rated diclofenac gel as significantly more effective in treating the pain of OA of the knee (p = 0.03) compared to placebo. There were no safety issues concerning adverse events or laboratory values. CONCLUSION: Diclofenac gel was effective and safe for relief of symptoms of OA of the knee over 3 weeks of dosing.     

Virus-induced over-expression of protein phosphatase 2A inhibits insulin signalling in chronic hepatitis C

BACKGROUND/AIMS: Hepatitis C virus (HCV) infection disturbs glucose and lipid metabolism contributing to the development of liver steatosis, insulin resistance and type 2 diabetes mellitus. On the other hand, insulin resistance and steatosis have been found to be associated with increased rates of fibrosis progression and lower rates of response to interferon therapy in chronic hepatitis C (CHC). The molecular mechanisms contributing to insulin resistance in CHC are not well understood. We have shown previously that protein phosphatase 2A (PP2A) is over-expressed in biopsies from patients with CHC. In this study, we tested if PP2A over-expression leads to insulin resistance. METHODS: We studied insulin signalling in cell lines that allow the regulated over-expression of HCV proteins and of the PP2A catalytic subunit (PP2Ac). Insulin signalling and PP2Ac expression were also studied in HCV transgenic mice and in liver biopsies from patients with CHC. RESULTS: Over-expression of PP2Ac in cells inhibited insulin signalling by dephosphorylation of PKB/Akt. PP2Ac over-expression and impaired insulin signalling were found in the liver of HCV transgenic mice and in liver biopsies of patients with CHC. CONCLUSIONS: HCV-induced over-expression of PP2A in the liver contributes to the pathogenesis of insulin resistance in patients with CHC.
