BACKGROUND: The fire victims are affected not only by bum and trauma but also carbon monoxide(CO) and hypoxia. It may be useful to triage mass casualties of fire field that preestimate the victim's injury sevrrities by experiments of measuring the concentration of CO and oxygen according to time progression. METHOD: We prepared one house of apartment as like usual residental environment. The mesuring of concentrations of CO and oxygen was started from firing. RESULT: 3.8 Min. after firing: CO concentration(0.007%) was reached to the level that can give rise to spontaneous headache. 5 Min.: The concentration of CO was incerased. At this level(0.012%), the victims of fire may be suffered severe headache inspite of mild movement. 5.5 Min.: At this time,0.02% of CO concentration that the victims can't escape by themselves was checked. 6 Min.; 0.08% was measured, almost patients may be unconscious and the symptoms will be more severe at this CO concentration because of hypoxia.6.4 Min.: It was absolutly impossible to be survival at this time due to incresing of CO concentration(0.195%) and decreasing of O2 concentration(5%). CONCLUSION: It is within 5.5 Min. that the patient can escape by themselves, and impossible to be survival more than 6.5 Min. in fire field. Rescuers and EMTs must consider time factor as well as sysmtoms of patients.

The humanitarian motivation of medical support from the three Scandinavian countries during the Korean War cannot be doubted, but the countries also had to be politically sensitive during this period. The fact that these countries only dispatched medical support, and that the team was not only for military purpose but also intended to help the civilians is a different point from the U.S. military medical support, which distinguished military medical support that is the U.S. Eighth Army, from the civilian treatment and relief, which is the UNCACK. In addition, medical support activities from the Scandinavian countries were bound to be flexible depending on the rapidly changing trend of war, active regions, and their support methods. At a time when the battle was fierce and the number of wounded soldiers increased, they had no choice but to concentrate on treating wounded soldiers, whether in Busan or Incheon. However, even while treating these wounded soldiers, they tried to treat and rescue civilians around the base area whenever they had chance. It is easily imaginable that in the urgent situation of war, the nature of medical support cannot be clearly divided into military or civilian if there is only one team that is operating. It is clear, however, that the common humanitarian purpose of rescuing and treating civilians affected the establishment of the National Medical Center in Seoul after the war. The Scandinavians had indeed remained even after the end of the war in to provide full support of establishing modern medical system in Korea. This suggests that modern Korean medical or public health system did not start to be developed in the 1960s like some researchers argue, but started a few years earlier during the time of the war with the support from the countries world-wide.

OBJECTIVE: We could measure diameters of lacrimal sac and surrounding bone thickness of normal Korean with accurate data by using orbital CT. METHODS: We measured the lacrimal sac, surrounding bone thickness, and frequency of Haller cell with thin-section computed tomography examinations in 115 normal Korean orbits with no signs of pathology related to the lacrimal drainage system for 1999 to 2001. RESULTS: The mean length of lacrimal sac was 10.45+/-1.96 mm, A-P width was 5.96+/-1.26 mm, L-R width was 3.72+/-0.92 mm. The surrounding bone thickness of upper portion of lacrimal sac was 6.46+/-1.40 mm, middle portion was 3.24+/-1.11 mm, lower portion was 0.78+/-0.23 mm. The frequency of Haller cell was 13.9%. The diameters of lacrimal sac and surrounding bone thickness were larger in males than females, and increasing tendency with aging. CONCLUSION: In this study, Korean lacrimal sac size was slightly smaller than the caucasian and Korean male's surrounding bone thickness was thicker than female. These data will be very helpful in making appropriate osteotomy by using the drill during dacryocystorhinostomy and avoiding unnecessary manipulation.

PURPOSE: This study was undertaken to determine the adequate cutoff value of the neonatal screening test to decrease recall and false-positive rates. METHODS: During the period of January 1999 through December in Asan Medical Center, newborn screening tests for phenylketonuria, congenital hypothyroidism, congenital adrenal hyperplasia, and galactosemia were performed in 3,775, 3,707, 3,783, and 3,806 newborns respectively using commercial ELISA kits. We reviewed and analyzed the recall rate at currently used cutoff values. RESULTS: 1)In neonatal screening test for congenital hypothyroidism, using a current cutoff value, 17 microIU/mL, the recall rate was 0.9% and using a 99.7% cutoff value, 21.3 microIU/mL, the predictive recall rate was 0.4%. There were no significant differences in the other reports that suggest adequate recall rate. 2)In neonatal screening test for phenylketonuria, using a current cutoff value, 3.6 mg/dL, the recall rate was 1.5% which was no significant difference compared with expected presumptive positive rate, 1.44%. 3)In neonatal screening test for congenital adrenal hyperplasia and galactosemia, the recall rate was high when using current cutoff value. But all results were within normal limits in reevaluation. CONCLUSION: The cutoff values of screening test which are currently recommended by manufacturers of commercial kits for congenital hypothyroidism, congenital adrenal hyperplasia and galactosemia, are needed to be reset to decrease the recall rate by false-positive results on the basis of data from an individual newborn screening laboratory.

OBJECTIVE: This study was to investigate the factors that influence the propensity of Koreans in choosing care settings of dementia patients. METHODS: This study analyzed the data from the '2014 Nationwide Survey on Dementia Awareness of Koreans' that was conducted by the National Institute of Dementia. Korean's perception of care burden for dementia was measured with grading on its types. Also its influences on preference for care between facilities and homes were evaluated using multivariate analysis with socio-demographic characteristics. RESULTS: In terms of preferred care settings, respondents preferred facilities over homes in case of themselves and their family, respectively 77.5% and 68.2%. The preference for facilities was significantly influenced by the respondents' age for both themselves and their family. Additionally, the perception of relatively higher emotional and physical burden compared to economic burden significantly influenced preference for facilities for their family. CONCLUSION: Improving public awareness and setting-up a practical social supporting system are needed to reduce emotional and physical burden as well as economic burden of dementia. Furthermore, building up an appropriate and safer communities for dementia patients and their caregivers is much demanded for reducing their burdens.

Primary spinal cord melanoma is a rare central nervous system malignant tumor. Usually it resembles an intradural extramedullary (IDEM) nerve sheath tumor or melanoma. We experienced a patient with upper thoracic primary IDEM spinal cord melanoma who was diagnosed to be with hydrocephalus and without intracranial lesions. Initial symptoms of the patient were related to the hydrocephalus and the primary spinal cord melanoma was diagnosed eight months later. At the first operation, complete resection was impossible and the patient refused additional radiotherapy or chemotherapy. At 22 months after surgery, the patient revisited our institution with recurrent both leg weakness. Leptomeningeal dissemination was present in the whole spinal cord and only partial resection of tumor was performed. The symptoms slightly improved after surgery. Primary spinal cord melanoma is extremely rare but complete resection and additional radiotherapy or chemotherapy can prolong the disease free interval. Hydrocephalus or signs of increased intracranial pressure may be the diagnostic clue of spinal cord malignancy and progression.

BACKGROUND: Aging population correspond with an increase in the numbers of dementia patients. Dementia decreases the quality of life of patients and care-givers. However, current pharmacological treatment is limited by modest efficacy and adverse effect. Nonpharmacological treatment for dementia has been considered to be a substitute treatment. Recently we developed a special planned program for dementia with depression. The aim of this study was to evaluate therapeutic effect of this program. METHODS: We included patients aged 65 and older who diagnosed dementia with depression in a geriatric institution from April to June, 2006. We surveyed their sex, age, education period, and histories of hypertension, smoking, and alcohol intake. Patients in experimental group carried out our program, including cooking, painting, recreation, and activity, 9 times for 60 minutes a session. All included patients were checked Korean Mini-Mental State Examination (K-MMSE) and Korean Form of Geriatric Depression Scale (KGDS) before starting program and after 3 months when programs finished. RESULTS: There was no difference in demographic factors between two groups. K-MMSE was significantly improved in experimental group compared with control group (P = 0.01). And, the KGDS was significantly improved in experimental group compared with control group (P = 0.00). CONCLUSION: Multidivisional program for social skill improvement was effective on treatment for patients of dementia with depression. Nonpharmacological treatment for dementia with depression would be developed and studied to enhance the qualities of life of patients and care of dementia.
