Reliability was examined using Cronbach coefficient alpha and corrected item-total correlation. A confirmatory factor analysis, based on a five-factor model, was performed using AMOS. Consecutive samples of 194 drug addicts, 197 psychiatric patients, and 599 college students were selected for the study. The mean age of participants (N= 1,000) was 24.8 yr. ...

Eighty totals of 180 patients with MS were enrolled in this cross-sectional study. They were asked to answer the valid and reliable Persian version of the Beck depression inventory (BDI) and Beck anxiety inventory (BAI) questionnaires. Demographic characteristics (sex and age), duration of the disease, disease course and Kurtzke Expanded Disability Status Scale (EDSS) were recorded for all participants. Mean BDI was 17.5 ± 11.4 in patients while mean BAI was17.7 ± 12.5 in all participants, respectively. Mean BDI and BAI were not statistically different between male and female participants. Patients with higher levels of disability (higher EDSS) had significant higher BDI and BAI scores and there was significant positive correlation between EDSS and BDI and BAI scores (rho=0.42, P<0.001, rho=0.35, P<0.001). Patients with SP (Secondary...

Chronic pain (eg, joint pain) is also a component of MS. Pain syndromes, including optic neuritis, complex regional pain syndrome [CRPS], and other less well-known syndromes, may respond to a variety of pharmacologic, surgical, or alternative interventions. MS patients may also experience iatrogenic pain. Some successful drug treatments for pain that are used in combination or alone include anticonvulsants, tricyclics, antidepressants, methylprednisolone, and narcotics. Surgical interventions, percutaneous compression-balloons, and radiofrequency ablation are other viable options for some pain syndromes. (Int J MS Care. 2000;2(3):30-34.) Dr. Kassirer is an Assistant Professor of Neurology at The International Journal of MS Care Editorial Board and Staff look forward to serving the needs of the MS community in the months to come.

Recent studies have indicated that TWEAK-Fn14 axis signaling may contribute to chronic autoimmune diseases. TWEAK expression via microglia in cortical lesions, presence of TWEAK + macrophages in inflamed leptomeninges, and absence of TWEAK/Fn14 expression in healthy brain implicates importance of this pathway in pathogenesis of multiple sclerosis lesions. TWEAK-Fn14 axis blockade has also shown promise in various multiple sclerosis animal models. Stimulation of the TWEAK/Fn14 pathway can result in activation of both canonical and noncanonical NF-ÎşB signaling and could also stimulate mitogen-activated protein kinase (MAPK) signaling pathways. Here, we have reviewed evidence of the possible role of TWEAK-Fn14 axis in pathophysiology of multiple sclerosis and experimental autoimmune encephalomyelitis (EAE) via neuroinflammation, tissue remodeling, blood-brain barrier (BBB) disruption, neurodegeneration, and astrogliosis.

Methods: This was a clinical-based study conducted from September 2009 to June 2010 in Tehran, Iran. A consecutive sample of female patients with MS was recruited from an outpatient clinic. The Female Sexual Function Index (FSFI) was used to evaluate sexual function. In addition neurological impairment was measured using the Kurtzke Expanded Disability Status Scale (EDSS), and depression was assessed using the Beck Depression Inventory-II (BDI-II). Univariate and multiple logistic regression analyses were performed in order to examine the association between sexual dysfunction and independent variables. Results: In all, 226 women participated in the study. Of these, 125 women (55.3%) met the criteria for sexual dysfunction. The mean age of participants was 35.7 years (SD = 8.07). The results obtained from multiple logistic regression analysis indicated that the disease duration (OR for the disease duration of equal or greater than 9 years = 3.13, %95 CI = 1.29-7.57, P = 0.01), the disease course (OR for secondary progressive MS = 3.96, %95 CI = 1.55-10.10, P = 0.004) and the BDI score (OR = 1.11, %95 CI = 1.07-1.16, P < 0.001) were significant factors contributing to sexual dysfunction in these patients. Conclusions: The findings from this study indicated that the duration and severity of the disease in addition to depression were the most significant factors that contributed to sexual dysfunction in women with multiple sclerosis. The burden of disease and sexual dysfunction suggests the need for further attention to this patient population.
The effect of vitamin A supplementation on stimulated T-cell proliferation with myelin oligodendrocyte glycoprotein in patients with multiple sclerosis

Vitamin A is known to play a role in the immune system. It has been recognized that some metabolites of vitamin A can be used effectively to treat experimental autoimmune encephalomyelitis (EAE). Aims: The effect of vitamin A as retinyl palmitate on T-cell proliferation in MS patients.

Our study included 108 patients who were dialyzed at least for 3 months. Before hemodialysis, blood samples were collected and serum levels of CRP, ferritin, albumin, phosphorus, parathyroid hormone, and hemoglobin were measured. Sleep disorders were confirmed by the presence of at least one of following criteria: insomnia, restless leg syndrome (RLS), obstructive sleep apnea syndrome (OSAS), narcolepsy, nightmare, sleepwalking, and poor sleep. 82.4% of patients demonstrated sleep disorders; insomnia (50%), RLS (32.4%), OSAS (7.4%), narcolepsy (15.7%), nightmare (15.7%), sleepwalking (0.9%), and poor sleep (71.3%). Our results revealed that CRP C3.8 lg/ml and advanced age were significantly associated with sleep disorders in these patients (p = 0.004 and p = 0.006, respectively). We concluded that inflammation has a close relation with sleep disorders in hemodialysis patients.

While the characteristics of the disease and the response of patients to disease-modifying therapies are generally comparable between the Middle East and other areas, significant barriers to achieving optimal care for MS exist in these developing nations. A group of physicians involved in the management of MS in ten Middle Eastern countries met to consider the future of MS care in the region, using a structured process to reach a consensus. Six key priorities were identified: early diagnosis and management of MS, the provision of multidisciplinary MS centres, patient engagement and better communication with stakeholders, regulatory body education and reimbursement, a commitment to research, and more therapy options with better benefit-to-risk ratios. The experts distilled these priorities into a single vision statement: "Optimization of patient-centred multidisciplinary strategies to improve the quality of life of people with MS. " These core principles will contribute to the development of a broader consensus on the future of care for MS in the Middle East.
