Forty-five patients with primary neoplasm of the spine, disgnosed and operated at Dept. of Orthopedic Surgery, Seoul National University Hospital, from 1970 to 1988, were reviewed in an attempt to analyze the incidence of the primary spine tumors and effectiveness of surgical treatment. Mean follow-up was 2.5 years. Among 29 benign tumors, 7 cases of osteoid osteoma, 6 cases of giant cell tumor, 4 cases of osteoblastoma and aneurysmal bone cyst, and 2 cases of fibrous dysplasia and osteochondroma, and others were identified. Of 16 malignant tumors, 6 cases of eosinophilic granuloms, 4 cases of chordoma, 3 cases of solitary plasmacytoms, and others were noted. 17 cases occurred in the anterior compartment, 18 cases in the posterior compartment, and 10 cases involved both compartments. Surgical treatment consisted of complete or near complete excision, decompression, and additional stabilization procedure when the stability of the vertebral column was compromised. Stablization was achieved either by fusion, strut bone graft, or by additional Zielke, Cotrel-Dubousset, or Luque-Harringtion instrumentation. The results were astisfactory in most of the cases with benign tumors except cases of giant cell tumor. The results in malignant tumor were satisfactory especially in eosinophilic granuloma and solitary plasmacytoma with respects to symptoms and survival, and this fact was attaibuted to good response to adjuvant chemotherapy and radiation therapy. Recent application of Cotrol-Dubousset or Zielke instrumentation after agressive resection made early ambulation a clinical reality.

PURPOSE: This study examines the change in distance from the corneal limbus to the insertion of the rectus muscles before and after disinsertion and retraction with a pair of fixation forceps during strabismus surgery. METHODS: In 38 strabismus patients, on 30 medial rectus muscles and 38 lateral rectus muscles, before and after disinsertion and retraction with a pair of fixation forceps, the distances from the corneal limbus to the upper, middle and lower parts of the insertion of the medial and lateral rectus muscles marked with methylene blue solution were measured. RESULTS: The distances between the corneal limbus and upper, middle and lower parts of the insertion after the disinsertion were reduced on, average 0.23 mm, 0.28 mm, and 0.18 mm, for the medial rectus muscle, respectively, and 0.21 mm, 0.28 mm, and 0.15 mm, for the lateral rectus muscle, respectively (P<0.05). The percentage of cases in which the advance from the corneal limbus to the insertion was greater than 0.5 mm was 33.3% for the medial rectus muscle, and 21.1% for the lateral rectus muscle. The lateral rectus muscle was disinserted, fixed with a pair of forceps, and subsequently, the distance from the upper, middle and lower parts to the corneal limbus were reduced to 0.36 mm, 0.43 mm, and 0.30 mm, respectively (P<0.05). The percentage of cases that advanced more than 1.0 mm was 13.2 %. The changes in distance from the upper, middle, and lower parts of insertion toward the limbus after disinsertion and retraction were 0.15 mm 0.15 mm, 0.16 mm, respectively (P<0.05). CONCLUSIONS: When performing the recession of the lateral rectus muscle, disinsertion of the rectus muscle, may result in a change of the site of insertion, which in turn might influence the outcome of strabismus surgery.

We reviewed surgical specimens from 11 patients with diffuse neurofibroma to define the specific clinicopathologic characteristics. Ten cases were cutaneous neurofibromas and one case was an uncommon gastrointestinal neurofibroma involving the rectum. The most frequent sites of involvement were the head and neck, especially the eyelids and the periorbital areas. They usually presented as a plaque-like elevation of the skin. They primarily occured in children and young adults and positive family histories of von Recklinghausen's neurofibromatosis were obtained in 45.4%. Pathologically, the involved skin & rectum were diffusely thickened by an infiltrative growing mass, showing proliferation of short fusiform cells in the uniform matrix of fine fibrillary collagen. The characteristic prominence of Wagner-Meissner bodies (45.4%) suggests they could be associated with pathogenesis of diffuse neurofibroma. On the basis of these findings, we could confirm diffuse neurofibroma to be a distinct form of neurofibroma.

We have experienced two cases of the intramedullary ependymomas in the cervicothoracic and thoracolumbar spinal cord. The myelographic studies showed complete block or fusiform filling defect of the dye and they were treated by total laminectomy with excision of the tumor mass. The histological studies verified them ependymomas and the patients have shown good improvement of the neurological defecits in postoperative period.

It was reported that many adverse effects occurred to the growth areas of the adolescent player due to repititous strain. The injuries mainly involved in the shoulder and elbow, and named as little leaguers Shoulder and Little Leaguers: Elbow in boy baseball player. But the stress fracture of olecranon epiphyseal plate was rare and reported in a few cases. We reported a case observed in an adolescent Judo Player.

PURPOSE: We report a case of Type 3 Waardenburg syndrome accompanied by intermittent exotropia, which had not previously been encountered in Korea along with the literature study. METHODS: A 5-year-old boy visited as a result of hypochromic heterochromic iridum in the right eye. Suspecting Type 3 Waardenburg syndrome, plain radiography, a hearing test, an alternate prism cover test and fundus examinations were performed and the presence of lateral displacement of the lacrimal puntum was evaluated. RESULTS: The presence of hypochromic heterochromic iridum, dysplasia of the left thumb, sensorineural deafness, dystopia canthorum along with a lateral displacement of the lacrimal puntum, albinism of the posterior pole upon a fundus examination, and intermittent exotropia with a 20 prism diopters of deviation were found. CONCLUSIONS: This patient showed the 4 criteria for a diagnosis of Type 3 Waardenburg syndrome including hypochromic heterochromic iridum, dystopia canthorum along with lateral displacement of the lacrimal puntum, sensorineural deafness, and a muscular system abnormality, i.e., dysplasia of the left thumb. He also showed intermittent exotropia.

PURPOSE: The purpose of this study was to identify the relationship between self-leadership and the perception of learning in nursing students. METHODS: A descriptive research design was used in this study. The participants were 378 nursing students in M city and C city who were surveyed between June 1 and June 30, 2014 using self-report questionnaires. The data was analyzed using SPSS WIN 21.0 Program, which determined frequency, percentage, mean, standard deviation; a One-way ANOVA; a Scheffe test; a Pearson correlation coefficient; and a Stepwise multiple regression analysis. RESULTS: There were significant positive correlations between nursing students' self-leadership and their perception of learning. In the multiple regression analysis, self-leadership was the most significant predictor in explaining nursing students' perception of learning. CONCLUSION: Study findings suggest that nursing students' self-leadership is defined as having an important influence on nursing students' perception of learning. In order to strengthen nursing students' self-leadership, there is a need to develop education programs that increase nursing students' self-leadership.
