Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease of probable autoimmune etiology. The MR images of patients with clinically suspected ADEM were retrospectively reviewed. The clinical symptoms occurred 5 days to 1 month after viral upper respiratory infection (4) and Coxsakie viral infection(1). The symptoms had begun with fever(3), headache(3), sore throat(1), and drowsy mental state (1), which progressed with monophasic course to altered mental change(2), extremity weakness(2), seizure(1) and/or cerebellary symptom(I) MRI findings of ADEM showed patchy(4), nonhemorrhagic(5), asymmetric(5) high signal intensity lesions on T2-weighted images. The number of the lesions was mostly multiple(4). The lesions mainly involved the brain stem(3) and subcortical white matter(3). Follow-up MR images of 13 days to 20 days after high dose steroid therapy showed marked improvement in two of three, which well correlated with clinical manifestations. MR findin of multiple, patchy, nonhemorrhagic and asymmetric lesions in subcortical white matter and brain stem on T2-weighted images seem to be characteristic features of ADEM, but nonspecific. Therefore, clinical correlation is required in evaluating ADEM.

Various kinds of spinal instrumentation have been developed for treatment of spinal disorders which are associated with instability. Recently, newly designed devices using pedicle screw were developed with advantages of short segment fixation and firm internal fixation. This is a retrospective clinical and roentgenographic study to evaluate the effectiveness of Cotrel 1. Of the 27 cases, spinal stenosis were 11, spondylolisthesis were 8, spondylolysis were 4, burst fracture were 2, metastatic bone tumor was 1, and failed back syndrome was 1 case. 2. Result of clinical evaluation by Hanley's criteria at last follow up were excellent in 7(27%), Good in 15(58% ), fair in 4(15%). (1 case of metastatic bone tumor was excluded). 3. In the cases of spondylolisthesis, we tried to reduce the displacement in 2 cases of Meyerding Grade II, and 1 case was reduced and 1 case was not reduced. In the cases of of Meyerding Grade I, no further displacement was developed. 4. The complications were observed in 10(37%)cases. A) Generalized complications were 2 cases of hematoma, 3 cases of superficial infection of wound, and 1 case of nerve root irritation. B) Failure in instrmentation were 1 case of screw breakage, 1 case of complete loss of fixation between screw and rod, and 2 cases of partial loss of fixation. 5. To prevent above mentioned complications in fixation of the instrument, the following factors are recommended: 1) Selection of the adequate length of rod. 2) Fixation of the additional implant such as security bolt when instability between screw and rod is predictable. 3) Selection of the closed head screw in the fixation of proximally sided screw if possible. 6. Cotrel-Dubousset instrument has many advantages such as rigid internal fixation, anatomical reduction, and good maintenance and also effective in reduction and maintenance of spondylolisthesis and in wide posterior decompression of spinal stenosis, but for prevention of some complications, precise use of instrument and good application of surgical technique will be needed.

A 68-year-old female had slightly elevated, dusky erythematous nodules on the right infraorbital and the right temple area. Topical, intralesional corticosteroids and oral antihistamines provided temporary but incomplete improvement. Follow up biopsy, four months after the first visit revealed a tiny gold acupuncture needle lodged at the center of the nodule. Subsequent skull series revealed seven more linear radiopaque densities on the corresponding sites to the skin nodules. A patch test and an intradermal test with gold chloride showed strongly positive reactions. Removal of the embedded needles led to disappearance of the cutaneous nodules and itching sensation in seven days.
