Anatomic torsion of globe around the sagittal axis occurs in a large variety of strabismus conditions which are infinitively more common than paralysis of cyclovertical muscles. The anterior half of the superior oblique fibers are probably more effective intorters. The posterior superior oblique fibers are more effective depressors. Anterior shift of the superior oblique tendon has been advocated for treatment of torsional aspect of the superior oblque palsy. We experienced two cases of symptomatic excyclotropia in unilateral superior oblique muscle palsy without substantial vertical deviation. We operated paretic superior oblique muscle with Harada-Ito operation which is anterior and lateral displacement of the anterior fibers of the superior oblique tendon. In two patients with unilateral superior oblique palsy, the excyclotorsional deviations were reduced to 15 degrees to 2 degrees of excyclotorsion in primary position of the gaze and from 15 degrees to 2 degrees of excyclotorsion in downward gaze. In another case the cyclodeviation was reduced from 7 degrees to 0 degree in downward gaze.

OBJECTIVE: To analyse the clinical aspects of vaginal approach for gynecologic pelvic surgery, we evaluated age distribution, parity, indications for hysterectomy, postoperative pathology, operating time, bleeding amount, weight of uterus, postoperative complications. resected uterus weight, operating time and bleeding amount based on operative procedure type. METHODS: We reviewed the medical records of the 136 patients who underwent vaginal approach for gynecologic pelvic surgery for the indications other than uterine prolapse from Jan. 1998 to April. 1998, and from July. 1999 to Sep. 2001 at Chosun University Hospital. RESULTS: We performed 136 cases of vaginal approach for gynecologic pelvic surgery. We performed 132 cases of total vaginal hysterectomy, 4 cases of transvaginal ovarian cystectomy, a high increased rate of vaginal approach for gynecologic pelvic surgery significantly. The most common indication for vaginal approach for gynecologic pelvic surgery was uterine leiomyoma (63.2%), followed by HSIL, adenomyosis, MIC of the cervix, and ovarian cyst. The operating time was within 90 min in almost cases (47.1%). The most common postoperaive pathologic finding was uterine leiomyoma (47.1%), followed by adenomyosis, uterine leiomyoma with adenomyosis, MIC of the cervix, HSIL, LSIL, ovarian serouscys- tadenoma, and endometrioma. There were 4 cases (2.9%) of cuff cellulitis, 2 cases of pelvic cellulitis (1.5%), 3 cases of hematoma formation (2.2%), 1 case of laparatomy (0.7%) as postoperative complications. etc. CONCLUSION: Vaginal approach for hysterectomy and ovarian cystectomy is a safe method for removing uterus even in the absence of prolapse. Recently it's indication is widened to the patient who has larger uterus and history of previous pelvic surgery. Because of it's advantage, Vaginal approach for hysterectomy and ovarian cystectomy would be the preferred method of gynecologic pelvic surgery in the future.

PURPOSE: The purpose of this research is to determine whether pontic metal substructures, which are currently used in clinical surgeries, are designed appropriately and identify the problems that can occur due to their shape, size, and position. Then it aimed to emphasize the importance of making and designing pontic metal substructures based on basic principles. MATERIALS AND METHODS: This research measured pontic basal surface (P1) used sample metal substructures in this study, gingiva margin (P2), and the porcelain thickness of maximum infrabulge of labial surface around 1/3 of cervix dentis (P3). One-way ANOVA analysis was carried out to test the differences among groups, Tukey Honestly Significant Difference Test was conducted for statistical analysis among groups. RESULTS: For porcelain thickness and SD value, the P1 part was 1.2 - 1.8 (±0.17) mm for experimental group 1, 1.2 - 1.7 (±0.17) mm for experimental group 2, and 0.4 - 2.8 (±0.92) mm for experimental group 3. Next, the P2 part was 1.4 - 1.6 (±0.07) mm for experimental group 1, 1.3 - 1.8 (±0.07) mm for experimental group 2, and 0.5 - 2.7 (±0.67) mm for experimental group 3. The P3 part was 1.4 - 1.7 (±0.10) mm for experimental group 1, 1.5 - 2 (±0.10) mm for experimental group 2, and 0.9 - 3.1 mm (±0.90) for experimental group 3. There was no significance when One-way ANOVA analysis/Tukey Honestly Significant Difference Test was conducted for statistical analysis among groups (P > 0.05). CONCLUSION: The suggested metal substructures can be used clinically as they meet the requirements that pontic must have.

Leiomyosarcoma is a malignant tumor that originates in the smooth muscle tissues and represents 5-10% of all soft-tissue sarcomas. It is most often found in the uterus, retroperitoneum, wall of the gastrointestinal tract, and subcutaneous tissue. Leiomyosarcomas of the larynx are extremely rare. Recently, we experienced a case of leiomyosarcoma of the larynx in a 82- year-old man who was considered initially to have as a benign tumor. Therefore we report a case of leiomyosarcoma of the larynx with a review of literature.

This experiment was performed to study the morphological responses of the thymic cortex of the mice after administration of BCG. Healthy adult mice weighing 25gm each were divided into normal and experimental groups. BCG[0.03X108-0.32X108 CFU] were injected subcutaneously to the animals every other day, and animals were sacrificed at 4 days, 1 week, 2 weeks and 8 weeks following the first injection. Thymus were removed immediately after sacrifice and transferred to cold phosphate buffered 2.5% glutaraldehyde-1.5% paraformaldehyde solution[pH 7.3], and cut into small pieces. Tissue samples were fixed for 2-3 hours in the same fixative, postfixed with phosphate buffered 1% osmium tetroxide solution[pH 7.3], dehydrated in a graded series of alcohol, and embedded in araldite mixture. Ultrathin sections stained with uranyl acetate and lead citrate were observed with a JEM 100CX-II electron microscope. The observed results were as follow : 1. In the early BCG treated groups, a few eosinophile leucocytes were observed, but more eosinophils were observed in later groups. Some elongated and bar-shaped lysosomes with eletron lucent gap were often obserced in the macrophages. 2. Cortical population of thymocytes in the thymus were reduced, whereas territoris of the epithelial reticular cells were expanded especially in 2 weeks and 8 weeks groups. Some portion of the thymic cortex exhibited large intercellular spaces, and a few nuclear bodies filled with materials of medium density were observed in the epithelial reticular cells. 3. In the 8 weeks groups, macrophages, plasma cells and eosinopile leucocytes and developing eosinophile leucocytes were often observed in the thymic cortex. Distended cisternae of granular endoplasmic reticula and newly forming prosecretory granulses in the Golgi complex were ovserved in som plasma cells. From the above results, it was suggested that repeated treatment with BCG could induce disturb the maturation and differentiation of the T lymphocytes. In turn, BCG, if repeatedly injected, may disturb the immunological medchanism.

The benign mesenchymoma, in which fibrous tissue is accompanied by two or more mesencymal components, occurs very rarely in the head and neck area. The majority appear in patients under 25 years of age, most commonly in the subcutaneous scalp, cheek, or tongue. There is a 20% recurrence rate. Wide surgical excision is the treatment of choice. We report a case of mesenchymoma in the nasopharynx which was removed by transpalatine approach with a brief review of literature.

Cancer management has become a major policy goal for the government of the Korea. As such, the government introduced the National Cancer Control Plan (NCCP) to reduce the individual and social burdens caused by cancer and to promote national health. During the past 25 years, 3 phases of the NCCP have been completed. During this time, the NCCP has changed significantly in all aspects of cancer control from prevention to survival. The targets for cancer control are increasing, and although some blind spots remain, new demands are emerging. The government initiated the fourth NCCP in March 2021, with the vision of “A Healthy Country with No Concerns about Cancer Anywhere at Any Time,” which aims to build and disseminate high-quality cancer data, reduce preventable cancer cases, and reduce gaps in cancer control. Its main strategies include (1) activation of cancer big data, (2) advancement of cancer prevention and screening, (3) improvement in cancer treatment and response, and (4) establishment of a foundation for balanced cancer control. The fourth NCCP has many positive expectations, similar to the last 3 plans; however, cross-domain support and participation are required to achieve positive results in cancer control. Notably, cancer remains the leading cause of death despite decades of management efforts and should continue to be managed carefully from a national perspective.

Shunt malfunctions that require surgical intervention during pregnancy and the postpartum period are rare. Furthermore, no study has reported on an acute shunt malfunction immediately after cesarean section. Here, we describe the case of a 32-yr-old woman who became drowsy 12 hr after cesarean section delivery of her second child. She had a ventriculoperitoneal shunt placed to treat hydrocephalus associated with meningitis at 26 yr of age. Marked ventriculomegaly was seen on brain computed tomography and her consciousness recovered temporarily after aspirating cerebrospinal fluid from the flushing device. At surgery, the distal catheter tip was plugged by a blood clot. We believe that the blood spilled over during the cesarean section. The clogged catheter end was simply cut off and the remaining catheter was repositioned in the peritoneal cavity. Her consciousness recovered fully.

OBJECTIVE: To assess the intrarater and interrater reliability of the supraspinatus thickness measured by ultrasonography (US) in normal subjects and to identify the relationship between the supraspinatus thickness measured by US and cross sectional area (CSA) of the supraspinatus muscle by magnetic resonance imaging (MRI) in hemiplegic patients. METHOD: We examined 20 shoulders of normal subjects and 10 shoulders of hemiplegic patients. In normal subjects, one examiner measured the supraspinatus thickness twice by US at the scapular notch and another examiner measured the supraspinatus thickness several days later. The intrarater and interrater reliability of supraspinatus thickness measurements were then evaluated. In hemiplegic patients, the supraspinatus thickness at the scapular notch was measured by US in affected side and compared with CSA of the supraspinatus muscle at the scapular notch and the Y-view of MRI. RESULTS: One examiner's supraspinatus thickness measurement average was 1.72+/-0.21 cm and 1.74+/-0.24 cm, and the other examiner's supraspinatus thickness measurement average was 1.74+/-0.22 cm in normal subjects. Intraclass correlation coefficients of intrarater and interrater examination were 0.91 and 0.88, respectively. For hemiplegic patients, the supraspinatus thickness measured by US was 1.66+/-0.13 cm and CSA by MRI was 4.83+/-0.88 cm2 at the Y-view and 5.61+/-1.19 cm2 at the scapular notch. The Pearson Correlation Coefficient between the supraspinatus thickness at the scapular notch and the CSA at the Y-view was 0.72 and that between the supraspinatus thickness and CSA at the scapular notch was 0.76. CONCLUSION: The supraspinatus thickness measurement by US is a reliable method and is positively correlated with the CSA of the supraspinatus muscle in MRI in hemiplegic patients. Therefore, supraspinatus thickness measurement by US can be used in the evaluation of muscle atrophy and to determine therapeutic effects in hemiplegic patients.
