Authors report five patients(four males and one female, aged 28-54 years) with intracranial meningioma in which 60Co-irradiation produced a beneficial effect. Radiation was delivered over period from 39 to 51 days with total does of 5000 to 5500 cGy. Irradiation alone was performed in two patients including one recurrent case ; irradiation followed by surgery in one, and postoperative irradiation for the residual tumor in two. Histopathological examination was done in four cases and more of them were malignant or hemangiopericytic type. Two cases of highly vascular tumors showed marked shrinkage of the tumor after irradiation. Another highly vascular meningiomas showed decrease of the tumor vascularity and degree of contrast enhancement in magnetic resonance image(MRI). One recurrent case developed a prominent cystic change suggesting development of tumor necrosis due to irradiation and the tumor growth has been arrested for one year after irradiation. In one patient with a cavernous sinus meningioma, the tumor with progressive growth after incomplete resection showed a definite decrease in its size. With these observations, it is suggested that ; 1) benign meningiomas may develop marked shrinkage, cystic change or decreased vascularity in response to irradiation ; 2) there is a tendency that irration may be helpful for the operation on highly vascular meningiomas ; 3) in patient with a high surgical risk, irradiation alone may be performed to obtain reduction of the tumor volume or arrest of growth ; 4) preoperative irradiation may facilitate surgical removal of the tumor by reducing amount of intraoperative bleeding even in benign meningiomas ; 5) as a sole treatment or a preoperative adjuvant therapy, irradiation should be considered in patients who are not favorable candidates for operation or radiosurgery.

BACKGROUND: Although the incidence of tsutsugamushi disease has been increasing in Korea, epidemiological and clinical characteristics of tsutsugamushi disease in Young?dong province have not been reported. METHODS: We retrospectively reviewed the medical records of 46 patients of tsutsugamushi disease who admitted at Gangneung Asan hospital from 1997 to 2001. RESULTS: Incidence of tsutsugamushi disease in Young-dong province had been increasing since 1999. Most patients were infected during agricultural work. The incidence of women was higher than that of men (65.2%). Characteristic laboratory finding was elevation of AST and ALT, hypoalbuminemia and thrombocytopenia. Despite fever, leukocytosis was found only in 20% of patients. Course of disease was relatively good in most patients, but complications such as pneumonia, acute renal failure, and shock developed in 26% of patients. In one case with acute renal failure and another case with pneumonia, the patients' condition aggravated in spite of doxycycline therapy, thus, hemodialysis and mechanical ventilator care were done respectively. Consequently, both patients recovered completely without chronic complication. Old age (>65 years), longer duration from onset of symptoms to admission (>10 days), hypoalbuminemia at admission(<2.6 g/dL) and leukocytosis could be used as a marker for prediction of complications. CONCLUSION: Incidence of tsutsugamushi disease increased in Young?dong region. Old age, delayed admission, hypoalbuminemia and leukocytosis could be used as marker for prediction of complications.

Objective: We evaluated the efficacy of a newly-developed spinal orthoses (V-LSO) by comparing the stabilizing effect, abdominal pressure, and comfort of 3 different semirigid LSOs (classic LSO, V-LSO, and CybertechⓇ ) during various body movements. Methods: Thirty healthy volunteers (23∼47 years, 24 males, 6 females) were selected. A dual inclinometer measured the range of motion (ROM) while the participants performed flexion/extension and lateral flexion of the lumbar spine with 3 LSOs.The LSO’s pressure on the abdominal surface was measured using 9 pressure sensors while lying, sitting, standing, flexion/extension, lateral flexion, axial rotation, and lifting a box. Comfort and subjective immobilization were analyzed by a questionnaire. Results: V-LSO had a statistically significant effect on flexion over CybertechⓇ . No significant differences were noted during extension and lateral flexion between the 3 LSOs. The abdominal pressure showed no significant differences while supine. While sitting, standing, and lifting a box, the mean abdominal pressure for V-LSO were significantly higher than those for Cybertech Ⓡ . During lumbar flexion, the mean abdominal pressures for classic LSO and V-LSO were significantly higher than that of CybertechⓇ . For extension, lateral flexion and axial rotation, the abdominal pressure for V-LSO was significantly higher than those of classic LSO and CybertechⓇ . In the subjective analysis, V-LSO and CybertechⓇ scored best for comfort. Conclusion The V-LSO and CybertechⓇ were more comfortable than the classic LSO, and hence, may have improved compliance with decreased discomfort. V-LSO may be superior to the other LSOs in restricting lumbar movement and increasing intraabdominal pressure.

Objective: To compare the convenience and effectiveness of the existing lumbosacral orthoses (LSO) (classic LSO and Cybertech) and a newly developed LSO (V-LSO) by analyzing postoperative data. Methods: This prospective cohort study was performed from May 2019 to November 2019 and enrolled and analyzed 88 patients with degenerative lumbar spine disease scheduled for elective lumbar surgery. Three types of LSO that were provided according to the time of patient registration were applied for 6 weeks. Patients were randomized into the classic LSO group (n=31), Cybertech group (n=26), and V-LSO group (n=31). All patients were assessed using the Oswestry Disability Index (ODI) preoperatively and underwent plain lumbar radiography (anteroposterior and lateral views) 10 days postoperatively. Lumbar lordosis (LS angle) and frontal imbalance were measured with and without LSO. At the sixth postoperative week, a follow-up assessment with the ODI and orthosis questionnaire was conducted. Results: No significant differences were found among the three groups in terms of the LS angle, frontal imbalance, ODI, and orthosis questionnaire results. When the change in the LS angle and frontal imbalance toward the reference value was defined as a positive change with and without LSO, the rate of positive change was significantly different in the V-LSO group (LS angle: 41.94% vs. 61.54% vs. 83.87%; p=0.003). Conclusion The newly developed LSO showed no difference regarding its effectiveness and compliance when compared with the existing LSO, but it was more effective in correcting lumbar lordosis.
