Authors analysed 19 cases with Cavernous Hemangiomas of Skeletal Muscles in Extremities. Those were confirmed clinicopathologically for the period of 2 years from October 1976 to September 1978, and following results were obtained. 1. The age of initial visit varied from 6 months to 42 years of age with the average of 17.7 years. Seventeen patients(89.5%) were under 30 years of age. 2. The age of initial onset of symptoms varied from birth to 36 years of age with the average of 13.1 years. Seventeen patients(89.5%) were under 20 years of age. 3. The duration of disease varied from 6 months to 17 years with the average of 4.6 years. 4. The ratio of male and female was 9:10. 5. Chief complaints were a swelling or mass in 17 cases(89.5%), pain in 13 cases(68.4%), tenderness in 6 cases(31.6%), and impairment of function in 5 cases(26.3%). 6 The size of a mass varied from a nut size to an adult fist one, and its shape appeared oval with the average 8.1 by 4.6 cm in 12 cases, and round with the average 5.5 cm in 7 cases. 7. The site of involvement distributed to lower extremities in 10 cases(52.7%), upper ones in 9 cases(47.4%). Among extremities(thigh, leg, arm and forearm) the most common site was forearm. 8. Considering the number of involed muscles, most frequently they developed in a single muscle with 11 cases(57.9%). 9. By history, The symptoms were initiated or aggravated by trauma in 3 cases(15.8%). 10. Plain roentgenograms showed the swelling of soft tissue in 9 cases(47.4%) and phleboliths in 8 cases(42.1%). 11.

PURPOSE: We describe clinical assessment of visual internal urethrotomy (VIU) as primary treatment modality in 69 men who presented with complete or partial obstructed urethral stricture. MATERIALS AND METHODS: The 63 patients with partial obstructed urethral stricture were treated by typical VIU. The 6 men with complete obstructed urethral stricture were treated by VIU using sound passed through previously placed suprapubic tract as guide. RESULTS: The procedure was completed successfully in 57 of the 63 men with partial obstructed (90.5%) and 3 of 6 patients with complete obstructed urethral stricture (50%). CONCLUSIONS: VIU is a safe and effective as primary treatment plan when urethral stricture is partial obstructed and the impassable urethral segment is shorter than 1.0cm.

PURPOSE: WHO (World Health Office) and WADEM (World Association of Disaster Emergency Medicine)have recommended that all countries should complete their preparedness for CBRNE disasters (chemical, biologic, radiological, nuclear, and explosive disaster) within a few years. To establish whether a biologic or chemical disaster plan is most appropriate in a given situation, essential information regarding biologic materials and chemicals should be provided to emergency personnel as rapidly as possible. METHODS: We prospectively investigated information systems operated by government bodies in Korea. We obtained data about toxic material information systems of Korea by contacting individuals in charge of toxic material information systems at seven government agencies between April and July 2007. RESULTS: There was no single toxic information system designated as a repository for all toxic material data in Korea. Instead, data were distributed among 9 institutes in 6 government cabinets. Moreover, redundant data were independently stored at four different cabinets or ministries the Ministry of Commerce, Industry and Energy; the Ministry of Labor; the National Emergency Management Agency; and the Ministry of Environment. Because each ministry or cabinet handled toxic material information system according to its own laws or legal guidelines, there were effectively eight sets of rules for toxic materials. CONCLUSION: Nine institutes in six government bodies were found to be operating computerized information systems for toxic materials independently, and four government bodies had redundant chemical information. In order to establish a central toxic material information center, a uniform set of guidelines for toxic materials should be established. Doing so, would result in financial savings, and improve the quality of information.

Purpose: The accessibility of medical facilities for cancer patients affects both their comfort and survival. Patients in rural areas have a higher socioeconomic burden and are more vulnerable to emergency situations than urban dwellers. This study examined the feasibility and effectiveness of a cancer care model integrating a regional cancer center (RCC) and public health center (PHC). Methods: This study analyzed the construction of a safety care network for cancer patients that integrated an RCC and PHC. Two public health institutions (an RCC in Gyeongnam and a PHC in Geochang County) collaborated on the development of the community care model. The study lasted 13 months beginning in February 2019 to February 2020. Results: The RCC developed the protocol for evaluating and measuring 27 cancer-related symptoms, conducted education for PHC nurses, and administered case counseling. The staff at the PHC registered, evaluated, and routinely monitored patients through home visits. A smartphone application and regular video conferences were incorporated to facilitate mutual communication. In total, 177 patients (mean age: 70.9 years; men: 59%) were enrolled from February 2019 to February 2020. Patients’ greatest unmet need was the presence of a nearby cancer treatment hospital (83%). In total, 28 (33%) and 44 (52%) participants answered that the care model was very helpful or helpful, respectively. Conclusion We confirmed that a combined RCC-PHC program for cancer patients in rural areas is feasible and can bring satisfaction to patients as a safety care network. This program could mitigate health inequalities caused by accessibility issues.

Limbic encephalitis is a rare paraneoplastic syndrome characterized by prominent memory impairment, affective and behavioral disturbances, and progressive intellectual deterioration. Among many different neoplasm known to cause limbic encephalitis, a small cell lung cancer is certainly the most frequently reported. We experienced a 64-years old male patient presented with clinical features consistent with limbic encephalitis. He was subsequently found to have small cell lung cancer and showed characteristic evolutional MRI features ; increased signal intensity on T2 weighted image in the bilateral medial temporal regions during early stage and progressive severe atrophy in the late stage.

Purpose: This study was performed to investigate the association of high age-adjusted shock index (AASI) with mortality in Korean children with trauma. Methods: The data of children (aged < 15 years) with trauma who visited an university hospital in Korea from 2010 through 2018 were reviewed. High AASI was defined by age groups as follows: < 12 months, ≥ 2.7; 12-23 months, ≥ 2.1; 2-4 years, ≥ 1.9; 5-11 years, ≥ 1.5; and 12-14 years, ≥ 1.1. Age, sex, transfer status, injury mechanism, hypotension, tachycardia, base deficit, hemoglobin concentration, trauma scores, hemorrhage-related procedures (transfusion and surgical interventions), and severe traumatic brain injury were compared according to high AASI and in-hospital mortality. The association of high AASI with the mortality was analyzed using logistic regression. Results: Of the 363 enrolled children, 29 (8.0%) had high AASI and 24 (6.6%) died. The children with high AASI showed worse trauma scores and underwent hemorrhage-related procedures more frequently, without a difference in the rate of the traumatic brain injury. High AASI was associated with in-hospital mortality (survivors, 6.5% vs. non-survivors, 29.2%; P = 0.001). This association remained significant after adjustment (adjusted odds ratio, 6.42; 95% confidence interval, 1.38-29.82). The other predictors were Glasgow Coma Scale (for increment of 1 point; 0.62; 0.53-0.72) and age (for increment of 1 year; 0.84; 0.73-0.97). High AASI showed a 29.2% sensitivity and 93.5% specificity for the mortality. Conclusion High AASI is associated with mortality, and have a high specificity but low sensitivity in Korean children with trauma. This predictor of mortality can be used prior to obtaining the results of laboratory markers of shock.

PURPOSE: The change of the marginal bone around dental implants have significance not only for the functional maintenance but also for the esthetic success of the implant. The purpose of this study was to investigate the load transfer of internal conical joint type implant according to marginal bone resorption by using the three-dimensional finite element analysis model. MATERIALS AND METHODS: The internal conical joint type system was selected as an experimental model. Finite element models of bone/implant/prosthesis complex were constructed. A load of 300 N was applied vertically beside 3 mm of implant axis. RESULTS: The pattern of stress distribution according to marginal bone resorption was similar. The maximum equivalent stress of implant was increase according to marginal bone resorption and the largest maximum equivalent stress was shown at model of 1 mm marginal bone resorption. Although marginal bone loss more than 1mm was occurred increasing of stress, the width of the stress increase was decreasing. CONCLUSION: According to these results, the exposure of thin neck portion of internal conical joint type implant is most important factor in stress increasing.

Clear cell carcinoma of the ovary is a clinicopathologic entity with distinct morphologic characteristics and known to be associated with poor prognosis irrespective of stage and prognostic benefits of chemotherapy have not been evidently demonstrated. This represents 2-3.6% of all ovarian malignancies. From October, 1991 to January, 1998, nine patients with primary clear cell carcinoma of the ovary treated in the deptartment of Gynecology and Obstetrics, University of Ulsan, Asan Medical Center were identified, and clinical and histologic review(including architectural pattern, mitotic activity, nuclear grading) was performed retrospectively. The age of the patients ranged from 30 to 67 year(mean+S.D.; 46.0+11.8) and the mean parity was 1.2 (+1.3). Five(55.6%) of nine patients had elevated level of CA 125. The size of the tumors varied from 3 cm to 20 cm with the mean maximal diameter of 12.1 (+6.3) cm. The FIGO stages of the patients were IC(6 cases, 66.7%), IIC (2 cases, 22.2%) and IV(1 case, 11.1%). All patients except one were treated by total abdominal hysterectomy and bilateral salpingoophorectomy with or without omentectomy and pelvic lymph node dissection. All except two were received postoperative chemotherapy with regimens such as CEC (cyclophosphamide + epirubicin + carboplatin), TC(taxol + carboplatin), CC(cyclophosphamide + carboplatin) or CAP (cyclophosphamide + adriamycin + cisplatin). The mean follow-up duration was 14.6 (+ 8.6) months and 8 patients were free of disease and one patient with stage IV disease died of disease during postoperative chemotherapy(4 months after surgery).
