BACKGROUND: To compare the diagnostic usefulness of dobutamine stress echocardiography(DSE) and 99mTc-methoxyisobutyl isonitrile SPECT (MIBI SPECT), two studies were performed simultaneously. METHOD: Fifty-six consecutive patients undergoing coronary angiogram and MIBI SPECT for clinical indications without clincal evidence of myocardial infarction were studied prospectively. During the DSE, MIBI was injected at peak stress, and post-stress images of MIBI SPECT were required on hour later. Both echocardiographic and MIBI SPECT images were visually analysed in a blind fashion. RESULTS: On the basis of coronary angiographic findings, the sensitivites of the DSE and MIBI SPECT (n=36) were 89% and 86%, respectively. The specificities of those (n=20) were 90% and 85%, respectively. Among 33 patients without resting perfusion defect on MIBI SPECT, resting regional wall motion abnormalities on DSE were found in only one patient, whereas, resting perfusion defect on MIBI SPECT were found in 9 patients among 41 patients without resting regional wall motion abnormalities on DSE. Among 17 patients who had resting perfusion defects with partial reversibility on MIBI SPECT, resting wall motion abnormalities were present in 11 patients and five of them showed improvement in the regional wall motion during low dose dobutamine infusion. CONCLUSION: Both dobutamine stress echocardiography and MIBI SPECT are useful methods in the detection of the coronary artery disease, however, MIBI SPECT seems to overestimate the regional ischemic myocardium with contractile reserve that can hardly be evaluated with MIBI SPECT.

Hertel and Naugle exophthalmometers were used to compare the variability and reproducibility, produced by various observers. Five examiners measured fifty two eyes of twenty-six normal subjects each by using two different exophthalmometers, respectively. The average coefficient of variation among five measurements was 5.6% in the right eye, 5.2% in the left eye and 2.1% in base line by Hertel exophthalmometer. The average coefficient of variation measured by Naugle exophthalmometer was 1.9% in both eyes and 0.8% in pupillary distance. In conclusion, Naugle exophthalmometer showed less variability and better reproducibility; it is more appropriate for comparative exophthalmetry.

PURPOSE: To evaluate ocular abnormalities in children with developmental disability and to find out whether any correlation exists between developmental disability and surgical outcome. METHODS: Totally 43 patients with the diagnosis of developmental disability were enrolled in this retrospective study. RESULTS: Mean follow-up was 4.54 +/- 2.35 year. 20 patients had exodeviation, 15 patients had esodeviation, 10 patients had dissociated vertical deviation and 4 patients had dyskinetic strabismus. 21 patients had surgery and the mean deviation angle was decreased from 36.67 +/- 15.70 PD to 5.33 +/- 5.93 PD in exotropia and 56.25 +/- 8.54 PD to 5.75 +/- 4.65 PD in esotropia. Refractive error was found in 33 patients (88.4%). 26 patients (60.5%) had monocular amblyopia and 17 patients (65.38%) showed improvement of visual acuity after treatment. CONCLUSIONS: Exotropia is the most common type strabismus in patients with developmental disability and dyskinetic strabismus is found in cerebral palsy. Strabismus Surgery for patients with stable angle deviation and amblyopia treatment is effective in children with developmental disability. However decision for surgery should be made after a long follow up period.

PURPOSE: This study was comprised of patients diagnosed with orbital pseudotumor classified according to the location and evaluated the clinical symptoms and treatment efficacy. PATIENTS AND METHOD: This study included 24 patients diagnosed with orbital pseudotumor between 1994 and 1999. The pseudotumor was localized by computed tomography and magnetic resonance imaging and classified into anterior, diffuse, apical, myositic, and lacrimal. The patients were all initially treated with steroid and additional biopsies were done in 4 patients (5 eyes) who exhibited prolonged symptoms, non-steroid responders and cases of recurrence. Cases diagnosed as sclerosing orbital pseudotumor were excluded. RESULTS: The response to treatment was high in the apical and diffuse types of orbital pseudotumor being 100% and 80% while the lacrimal and myositic types were 57.1% and 54.5%. The lacrimal type showed the highest recurrence rate of 42.9% followed by the myositic and anterior types being 25% and 20%. CONCLUSION: This study is the first in our country to reveal the treatment efficacy of orbital pseudotumors according to location. The orbital pseudotumors were localized by computed tomography and magnetic resonance imaging and classified to compare treatment efficacy and recurrence rates between the different types providing a basis upon which further studies may eventually help in the treatment and prognosis of orbital pseudotumors.

BACKGROUND/AIMS: Combined esophageal variceal ligation and sclerotherapy has been hypothesized to be more effective for the control of bleeding esophageal varices than ligation alone. The present study was to compare the combined therapy with ligation alone in terms of variceal eradication, rebleeding, complication and survival rates in patients with bleeding esophageal varices. METHODS: Thirty-eight patients with bleeding esophageal varices were randomly assigned to receive ligation alone in 20 patients or the combined therapy in 18 patients. The clinical and endoscopic characteristics of patients in the ligation group were similar to those of patients in the combination group. In the combination group, 1-3 mL of ethanolamine was injected proximal to each ligated site. Treatments were repeated every 2- to 3-month until varices were eradicated. RESULTS: No significant differences were found between the ligation and combination groups in variceal eradication rates (70% vs. 72%), numbers of endoscopic sessions required to achieve eradication (3.5+/-0.33 vs. 3.3+/-0.31), rebleeding rates (30% vs. 28%) or 2-yr cumulative survival rates (95% vs. 75%). There were significantly more complications in the combination group (25% vs. 89%, p=0.001). CONCLUSION: Ligation alone is recommended rather than the combined ligation and sclerotherapy because of its lower complication rates.
