Multiple sclerosis (MS) is the most common cause of disability after trauma in young adults in Northern Hemisphere; it imposes a major burden on the affected young people. A significant association between MS and demyelinating peripheral neuropathy which might be due to common pathogenesis for the central and peripheral nerves demyelination has been reported in several studies. We aimed to assess if there is any peripheral nervous system involvement in a sample of Iranian MS population. Extensive nerve conduction studies (NCS) were conducted in 20 MS patients according to McDonald criteria, and 20 age and gender matched healthy appearing controls. The F-wave ratio was calculated through placing the minimum amount of F-wave proximal latency after 10 stimuli and median or tibial nerves compound motor action potential (CMAP) proximal latency in the corresponding formula. Data were compared between groups. Finally, we found the significantly lower median and tibial nerves conduction velocities (NCV) in MS patients than healthy controls (P=0.008 and 0.003 respectively, Independent Samples t-test). Also, tibial NCV had a significant statistical correlation with Kurtzke’s expanded disability scale score (EDSS) as patients with higher EDSS had lower tibial NCV (Pearson's correlation coefficient, r2=0.8). No statistical relationship was found between MS subtypes and NCS parameters. Although we found some electrodiagnostic abnormalities in Iranian MS patients in comparison to the healthy participants, these differences were small and inconclusive. More extensive well-designed electrodiagnostic studies for evaluation of peripheral nervous system involvement and its probable pattern in these patients seems to be needed.

Medically unexplained symptoms are physical symptoms, which cannot be explained by organic ýcauses. This study aimed to investigate mental health in patients with medically unexplained ýphysical symptoms. ý
One hundred outpatients who were admitted to the Electro Diagnosis Clinic of Imam Khomeini ýhospital, Ahvaz/Iran, participated in this study. Data were collected using physical examination, ýparaclinical examinations, and SCL-90-R, and analyzed through multivariate analysis of variance ýý (MANOVA), Chi-square test and Fisher’s exact test. ý
The findings revealed significant differences between clients with medically explained and ýunexplained symptoms in obsessive compulsive and somatization (p0.05).ý
The present study suggested an association between some psychological problems and somatic ýsymptoms. Therefore, screening for psychological impairments can improve clinical outcomes.
