Hypoglycemia sometimes manifests as focal neurologic deficits simulating cerebrovascular disease. Symptoms are usually resolved by glucose infusion, but persistent hemiplegia is rarely reported. A 68-year-old diabetic woman on oral hypoglycemic agent(OHA) was admitted with right hemiplegia and global aphasia. Blood glucose level was 29 mg/dl on admission. No evidence of cerebral infarct or underlying brain disease could be found on initial brain CT and follow up MRI. Focal stenosis or occlusion was also absent on MR angiography. Hemiplegia and aphasia were not improved despite adequate therapy. Hypoglycemic hemiplegia should be suspected in all diabetic patients using insulin or OHA with stroke-like episode, and we suggest that prolonged hypoglycemia may be related to persistence of neurologic deficits.

From January 1970 through December 1984, 15 patients with sinonasal Non-Hodgkin's lymphoma combined to the head and neck were treated by external irradiation. 13 patients were stage IE and 2 were stage IIE by Ann Arbor Classification. However, when using TNM system, 7 were locally advanced T3, T4 lesions. All patients had follow up from 3.7 to 16 years with the median follow-up of 8.5 years. The overall actuarial 5-year survival rates were 25%, 28% for IE and 0% for IIE. Total tumor dose varied from 40 to 68 Gy. 100% complete response with a total tumor dose of more than 55 Gy and 73% complete response with less than 55 Gy. When the disease was staged using the TNM (AJC) system, the five-year disease free survival for T1 and T2 patients was 50% as compared with 14% for T3 and T4. Failure rate by stage was 33% (2/6) for T1 and T2, 86% (6/7) for T3 and T4, and 100% (2/2) for IIE. The results suggest that 1. Higher CR could be obtained with a total tumor dose of more than 55 Gy. 2. Use of TNM staging system is as important as Ann arbor in management of sinonasal NHL. 3. The addition of combination chemotherapy should be considered for T3, T4 and IIE the sinonasal Non-Hodgkin's lymphoma although the disease is limited to head and neck.

Yonsei Cancer Center developed an RF(Radiofrequency) capacitive type heating device, GHT-RF8(Greenytherm) in cooperation with Green Cross Medical Corp., Korea in 1986 for the first time in Korea. Cooperative clinical studies of hyperthermia for the treatment of cancer using GHT-RF8 were conducted by Yonsei Cancer Center in collaboration with the Presbyterian Medical Center, Chonju, Korea. A total of forty patients with various histologically proven malignant tumors, including superficial (N = 13) and deep-seated tumors (N = 27), were treated with this newly developed heating device in conjunction with radiotherapy (N = 38) or chemotherapy (N = 2) at two different institutes between October 1986 and September 1987. These patients were locally far advanced or recurrent cases and considered to be refractory to conventional cancer treatment modalities. Radiotherapy was given in 200cGy per day, five times a week fractionations with a total tumor dose of 50-60Gy in 5-6 weeks. Within an hour after radiotherapy, the RF capacitive type of hyperthermia was given two times a week for a total of 4-10 treatment sessions and an attempt was made to maintain the tumor temperature at 41-45 degrees C for 30-60 minutes. Of forty patients treated, 14 patients with deep-seated tumors showed complete response and 20 patients showed partial response. The overall response rate was 85% (34 out of 40 patients) and only 6 patients showed no response. Complications from this treatment were mainly burns, superficial first degree burn in 2 cases, second degree in 4 cases and subcutaneous fat necrosis was observed in 2 cases.

Purpose: Recently, there has been an increasing number of kickboard injuries at our orthopedic clinic and emergency room. Therefore, this study is to identify the incidence and characteristics of nonmotorized and electric kickboard injuries with emergency room surveillance. Methods: Between August 2018 and January 2021, patients who visited the emergency room of a tertiary hospital with nonmotorized and electric kickboard injuries were included. The incidence, severity, and characteristics were analyzed. Results: There were a total of 204 patients who visited our emergency room during the study period. There were 139 nonmotorized kickboard injuries with 115 minor, 11 moderate, and 13 severe injuries. Fifty-six electric kickboard injuries were 47 minor, one moderate, and eight severe injuries. The incidence of injury depended on-site and was as follows: face and head (63.7%), upper extremity, lower extremity, abdomen and chest, and spine. Conclusion Face and head injuries were the most common injuries in body part, while minor trauma was the most common diagnosis. With the increasing incidence of kickboard injuries, we should be more mindful that protective equipment and safety rules may be necessary.

The trial of external quality assessment for inborn error of metabolism was performed in 2003. A total 10 specimens for neonatal screening tests were distributed to 43 laboratories with a response rate of 83%. All the control materials were sent as a filter paper form. Each laboratory replied the test result as the screening items they were doing as a rountine test at the reception of the specimen among PKU screening, neonatal TSH, neonatal T4(total/free), galactosemia screen, homocytinuria screen and histidinemia screen. The mean, SD, and CV were analyzed.

Rhabdomyosarcoma is a highly malignant soft tissue sarcoma that car arise in any site of the body containing striated muscle or its mesenchymal analgae. It is the most common childhood sarcoma with two peak age frequencies, one at ages 2 to 6, and one in the adolescence. The site, stage and extent of disease, and pathologic characteristics of the tumor contribute to prognostic factors that influence therapeutic decisions. The results of treatment of 52 patients with rhabdomyosarcoma, who were treated at Department of Radiation Oncology. Yonsei University College of Medicine, Yonsei Cancer Center from 1976 to 1987 were retrospectively analyzed. The most frequent clinical group and primary sites were IRS group III(57.7%) and head and neck (42.3%) including orbit (11.5%) and parameningeal region(13.5%). The overall and disease free 5 year survival rate of eligible 41 patients were 31.7%, 29.3%, respectively. The complete remission(CR) rate was 50% in clinical group III and 0% in IV. Primary tumors of the orbit, clinical group I and embryonal subtype had the best prognosis. The survival rate was improved by addition of chemotherapy to operation and radiation therapy.

A retrospective review of fifty patients with carcinoma of hypopharynx treated with RT+/-surgery was studied for eleven-year period from 1974 to 1984. Of the 50 patients, 46 were pyriform sinus in origin, 4 were posterior pharyngeal wall. Eighty-eight percent of patients were locoregionally advance (stage III, IV) and 78% of patients presented cervical lymphadenopathy. 5-year disease-free survival rate of the pyriform sinus ca. was 25.4% in RT alone group, 80% in combined modality group and 30.6% in overall. Local control rate with RT alone in early stage (II) was excellent (100%), however combined modality appears to be better for local control (80%) in advanced stage (III, IV) as compared with that of RT alone group (32%). On basis of this study, RT alone is effective in terms of local control and functional preservation in treatment of early stage of pyriform sinus ca. while surgery can be reserved for salvage purpose when RT fails and combined modality is recommended in patients with locally advanced stage for better local control and survival.

Twelve patients with primary lymphomas of the central nervous system were treated in the Department of Radiation Oncology, Yonsei University College of Medicine, between 1976 and 1987. There were seven males and five females ranging from 19 to 63 years of age. They had single (6 cases) or multiple (6 cases) discrete intracerebral nodules. All patients were treated with radiation therapy. Surgical resection was performed in five cases and intrathecal chemotherapy with methotrexate was performed in seven cases after radiotherapy. All patients except one had received whole brain irradiation with a median dose of 4000 cGy. The radiation dose for a primary tumor was 4800-6000 cGy (median 5560 cGy). Initial response to radiation was excellent with a 91.7% complete response rate, but late recurrences were noted and the median survival was 42.3 months. Intracranial recurrences were observed in two patients who received less than 4000 cGy to the whole brain without intrathecal chemotherapy. Although intracranial recurrence was not seen in the patients receiving intrathecal chemotherapy after radiation, a high incidence of necrotizing leukoencephalopathy was noted. High dose irradiation with a minimum of 4000 cGy to the whole brain and more than 5000 cGy to the primary tumor is recommended for the treatment of primary CNS lymphomas. Combined use of chemotherapy should be carefully attempted because of the increased toxicity.

There are limited data evaluating the relationship between influenza treatment and hospitalization duration. Our purpose assessed the association between different treatments and hospital stay among Korean pediatric influenza patients. Total 770 children < or = 15 yr-of-age hospitalized with community-acquired laboratory-confirmed influenza at three large urban tertiary care hospitals were identified through a retrospective medical chart review. Demographic, clinical, and cost data were extracted and a multivariable linear regression model was used to assess the associations between influenza treatment types and hospital stay. Overall, there were 81% of the patients hospitalized with laboratory-confirmed influenza who received antibiotic monotherapy whereas only 4% of the patients received oseltamivir monotherapy. The mean treatment-related charges for hospitalizations treated with antibiotics, alone or with oseltamivir, were significantly higher than those treated with oseltamivir-only (P < 0.001). Influenza patients treated with antibiotics-only and antibiotics/oseltamivir combination therapy showed 44.9% and 28.2%, respectively, longer duration of hospitalization compared to those treated with oseltamivir-only. Patients treated with antibiotics, alone or combined with oseltamivir, were associated with longer hospitalization and significantly higher medical charges, compared to patients treated with oseltamivir alone. In Korea, there is a need for more judicious use of antibiotics, appropriate use of influenza rapid testing.
