Purpose : To determine the usefulness of MR imaging and MR angiography (MRA) in the evaluation of patientswith hemifacial spasm. Material and Methods : One hundred and twenty-five patients with hemifacial spasm wereincluded in this study. Axial T1-, T2-weighted images, proton density image (3mm thickness, 256x192) and 3-D TOFMRA were performed. Relation between facial nerve and adjacent arterial structures was carefully evaluated, whichwas correlated with surgical findings. Results : MRA identified the presence of offending vessels at the root exitzone of facial nerve and its origin in 117 patients(52 PICA, 50 AICA, 6 vertebral artery, 9 dual vessels). Therewere 4 false negatives and 4 false positives. Vascular groove at the root exit zone was identified in 52 cases,but there was no positive correlation between severity and duration of symptoms. The presence of ipsilateral orcontralateral distal loop formation of vertebral artery were noted in 63 patients. In addition, 4 cases ofneoplastic and vascular lesions were also demonstrated on MR imaging. Conclusion : Combination of MR imaging andMRA is an useful screening modality in the presurgical evaluation of hemifacial spasm, which can demonstrate theoffending vessels as well as other pathologic lesions.

Objective. To evaluate the prevalence and risk factors of upper extremity musculoskeletal diseases (MSDs) among Korean farmers. Methods. The study was carried out from June 2013 to August 2015 on 850 farmers and 203 non-farmers (controls) in Gyeongnam Province. Physical examinations were performed by rheumatologists, orthopedists, and rehabilitation specialists. Plain radiography, a nerve conduction examination, and magnetic resonance imaging were performed, and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire was used to assess upper extremity function. Results. Thirty-four different types of upper extremity MSDs were detected in the 1,053 study subjects. The prevalence of any MSD in farmers was 8.96-fold higher than in control (p<0.001). The most obvious difference in prevalence between farmers and non-farmers was hand osteoarthritis (48.2% vs. 4.9%). Mean total DASH score was higher for farmers than non-farmers (14.29±13.66 vs. 10.03±10.85, p<0.001). Among farmers, myofascial pain syndrome, rotator cuff tear, and epicondylitis were more prevalent among overhead workers (growing persimmons, pears, and grapes) than in non-overhead workers (growing rice and upland crops). The following factors were associated with a rotator cuff tear; older age, overhead work, high waist circumference, and lower level of education. Hand osteoarthritis was found to be associated with older age, a female gender, high waist circumference, and longer total work time. Conclusion. The prevalence of upper extremity MSDs is much higher in farmers than non-farmers and greater still for farmers doing overhead work. Various factors contribute to the occurrence of upper extremity MSDs, and thus, the authors suggest an efficient preventive strategy, which involves consideration of type of work and risk factors, be established for farmers to reduce upper extremity MSDs.
