PURPOSE: When recurrent dissociated vertical deviation (DVD) is cosmetically objectionable after superior rectus recession is used to surgically treat DVD, inferior rectus resection or superior rectus re-recession should be considered. The effect of re-recession of the superior rectus was, therefore, evaluated as a treatment of recurrent DVD. METHODS: We retrospectively reviewed the medical records of 9 eyes from 7 patients who had undergone superior rectus re-recession as a second surgery due to recurrence after superior rectus recession for DVD. RESULTS: The mean follow-up period after re-recession of the superior rectus was 32.1 (22~66) months. The preoperative mean deviation was 16.0 prism diopters (PD), and the postoperative mean deviation was 4.9PD. According to the classification of recurrent DVD by Scott, the surgical results of five eyes were excellent (0~4PD), those of 2 eyes were good (10~14PD), and those of 2 eyes were fair. The mean corrected DVD was 4.1PD per 1 mm recession. CONCLUSIONS: Postoperatively, 7 of 9 eyes (77.7%) were aligned within 9PD. In cases of recurrent DVD, superior rectus re-recession yielded satisfactory results with minimum surgery on the superior rectus. The results of this study will be helpful in deciding surgical amount of superior rectus re-recession to be performed.

Hydatid cysts are caused by an infestation with larval tapeworms of the genus Echinococcus. The disease is endemic in developing countries but has rarely been reported from immigrant workers in Korea. This paper reports a case of hepatic hydatid cyst in a 27-year-old female. She was referred with abdominal pain that had persisted for the past 2 months. The patient was a foreign worker from Mongolia. The physical examination was unremarkable, and blood tests showed peripheral blood eosinophilia and elevated liver enzymes. Abdominal ultrasonography showed a well-circumscribed cystic mass with septation in the liver. A surgical resection was performed for complete removal. After uncomplicated postoperative recovery, the patient was discharged with albendazole 400 mg twice daily. The hydatid cyst is an important disease that should be considered in the differential diagnosis of cystic lesions in the liver, particularly in those who have lived in endemic areas. A correct early diagnosis based on the typical image findings is important for early treatment before the rupture of the cyst, which is associated with low morbidity and mortality. A current surgical resection combined albendazole are effective treatments for hepatic hydatid cysts, associated with low recurrence rates.

Sacrococcygeal teratoma is a rare tumor, it occurs once in every 40,000 live births. Most of the reported cases appear in female infant (M:F=1:4). They deserve clinical attention because they are potentially malignant and are curable if diagnosed and treated early. The patients may have associated congenital anomalies. This patient has spina bifida cystica in lower sacrum. Brief review of related literature is included in the report.

We evaluated the antihypertensive effect of amlodipine, a calcium channel bloker, in 35 cases of essential hypertention. After 12 weeks' administration(5~10mg q.d.), the following results were obtained : 1) The systoloic and diastolic blood pressure were decreased significantly(170.3+/-12.2mmHg vs 143.7+/-13.0mmHg p<0.01 and 104.7+/-5.9mmHg vs 87.8+/-6.5mmHg, p<0.01, respectively) but the heart rate was independant of amlodipine administration. 2) The systolic blood pressure was lowered by 20mmHg or more in 26(76.5%) of 34 patients and the diastolic pressure was lowered by 10mmHg or more in 26(76.5%) of 34 patients at 12 weeks after amlodipine administration. 3) The adverse effects of amlodipine were dizziness in 5, edema in 5, indigestion in 3, constipation in 2, headache, flushing, insomnia in 1 patient respectively and only one of them discontinued amlodipine administration due to severs facial flushing and skin eruption.

This study evaluated the efficacy of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 31 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 31 volunteers with the same protocol. The shade change (DeltaE*, color difference) of 12 anterior teeth was measured using Colorimerter and Vitapan classical shade guide. The shade change of overall teeth in the experimental group was significantly greater than that in the control group which was measured using Colorimeter. There was also a significant difference between baseline and 14 weeks or 26 weeks though color rebounding phenomenon occurred as time went by. Small shade change difference can be measured accurately using Colorimeter than using Vitapan classical shade guide.

This study evaluated the safety of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 37 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 34 volunteers with the same protocol. There was no difference between experimental group and control group using electric pulp test. In the result of gingival inflammation index and tooth sensitivity test, there was mild pain response in experimental group but it disappeared as time went by. Therefore, safety of the office bleaching gel containing 30% hydrogen peroxide was confirmed.

Benign neoplasms of the stomach are uncommon in children. They include adenomatous and hyperplastic polpys, leiomyomas, lipomas, and other lesions. Gastric leiomyoma in childhood represent only 1% of all gastrointestinal neoplasms reported, and slightly more than half of these are gastric. The tumor arises in the muscle layer of the stomach and is usually intragastric and submucosal. Barium contrast studies are useful in localizing leiomyoma with significant intramural or submucosal growth. An endoscopy can permit histologic confirmation if the tumor has eroded through the mucosa. Differentiation however, of malignant lesions from benign submucosal leiomyomas may be difficult. Using endoscopic ultrasonund imaging, highly accurate gastrointestinal tumor characterization, especially submucosal masses, and differentiation of malignant from benign lesion are now relatively possible without surgery. We experienced a case of a gastric submucosal tumor regarded as a leiomyoma, which was diagnosed using endoscopic ultrasonography, and report the findings with a review of related literatures.

PURPOSE: The schwannoma is a tumor originating from Schwann cell proliferation. Schwannoma is a rare disease, making up only 1% of all the tumors that develop in the orbit. Schwannomas usually arise from the choroids or the ciliary body, and occurrence in the conjunctiva is especially rare. Few cases have been reported worldwide, and no cases have been reported in Korea thus far. We report our case along with a literature review. CASE SUMMARY: A 31-year-old male patient visited our department with a history of discomfort of in his right eye for the past 5 years caused by a bulbar conjunctival mass. On ophthalmologic examination, a 5x3x3 mm, elevated, yellowish mass with a smooth surface was observed on the bulbar conjunctiva adjacent to the superonasal limbus near the 2 o'clock area of the right eye. We performed excision and biopsy for diagnosis and treatment of the bulbar conjunctival mass and confirmed the pathologic report for the diagnosis of schwannoma.

OBJECTIVE: A growing body of research has documented that occupational stress is associated with workers' adverse health outcomes such as mental distress, depression and burnout. This study was performed to identify the relationship between occupational stress and burnout among occupational therapists in Korea. METHODS: A total of 226 occupational therapists registered in the Korean Association of Occupational Therapist participated in the study. A self-administered questionnaire was used to assess demographics, subjective health status, work-related factors, occupational stress and burnout. Burnout was measured by Maslach Burnout Inventory (MBI). Occupational stressors were assessed using 26-items of the Korean Occupational Stress Scale (KOSS-26(R)). This scale consists of items targeting at physical environment, job demand, insufficient job control, interpersonal conflict, job insecurity, lack of reward, organizational system and occupational climate. Simple and multiple regression analyses were performed to investigate the relationship between 8 occupational stressors and burnout, separately. SAS 9.1 version was used for the analyses, and a P<0.05 was considered significant. RESULTS: The results show that all occupational stressors were associated with burnout after adjustment for control variables. Occupational stressors accounted for from 14.39% (p<0.001, organizational system) to 33.21% (p<0.001, occupational climate) of the variance in burnout. CONCLUSION: These results suggest that occupational stress might play a significant role in increasing the risk of burnout among occupational therapists.

A 56-year-old male with a gastrointestinal stromal tumor (GIST) underwent surgical resection of the tumor. Nine months after surgery, imatinib therapy was initiated because of the discovery of metastatic tumors in the left adrenal gland and in a lymph node of the peritoneum. Seventeen months later, the patient achieved complete remission (CR) and imatinib therapy was continued. However, 48 months after initiation of imatinib therapy, computed tomography scans revealed a left adrenal gland metastasis and the patient underwent left adrenalectomy. Immunohistochemical staining indicated that the spindle-shaped cells of the resected tumor were positive for C-kit, thus confirming metastasis of the GIST. This is the first report from Korea of an adrenal gland metastasis from a GIST. Worldwide, only two such cases have been reported. Here, we describe the first case of a distant recurrence of a GIST in the left adrenal gland after CR had been achieved with the aid of surgical resection and imatinib therapy.
