The shortage of available organ donors is a significant problem and various efforts have been made to avoid the loss of organ donors. Among these, extracorporeal membrane oxygenation (ECMO) has been introduced to help support and manage potential donors. Many traumatic brain injury patients have healthy organs that might be eligible for donation for transplantation. However, the condition of a donor with a fatal brain injury may rapidly deteriorate prior to brain death determination; this frequently results in the loss of eligible donors. Here, we report the use of venoarterial ECMO to support a potential donor with a fatal brain injury before brain death determination, and thereby preserve donor organs. The patient successfully donated his liver and kidneys after brain death determination.

Purpose: The purpose of this study was to investigate the cause of acute fatal poisoning and the time of death by analyzing the National Emergency Department Information System (NEDIS) of South Korea. Methods: The NEDIS data from 2014 to 2018 excluding non-medical visits were used for this study. The patients with acute poisoning were extracted using diagnostic codes. The toxic substances were classified into pharmaceuticals, pesticides, gases, artificial poisonous substances, and natural toxic substances. Patients were classified according to the time of death, place of death, and region. In each case, the most causative substances of poisoning were identified. Results: There were 380,531 patients including poisoning-related diagnoses, of which 4,148 (1.1%) died, and the WHO age-standardized mortality rate was 4.8 per 100,000. Analysis of 2,702 death patients whose primary diagnosis was acute poisoning, the most common cause of poisoning death was pesticides (62%), followed by therapeutic drugs, gas, and artificial toxic substances. Herbicides were the most common pesticides at 64.5%. The proportion of mortality by time, hyperacute (<6 h) 27.9%, acute (6-24 h) 32.6%, subacute (1-7 d) 29.7%, and delayed period (>7 d) were 9.8%. Conclusion This study suggests that the most common cause of poisoning death was pesticides, and 60% of deaths occurred within 24 hours. The 71% of mortality from pesticides occurred within 6-24 hours, but mortality from gas was mostly within 6 hours. According to the geographic region, the primary cause of poisoning death was varied to pesticides or pharmaceuticals.

The use of high-pressure air instruments has become more common. Consequently, there have been a number of cases of orbital emphysema caused by contact with high-pressure air. In this case, a 62-year-old male patient visited an emergency medical center after his left eye was shot by an air compressor gun that was used to wash cars. Lacerations were observed in the upper and lower eyelids of his left eye. Radiological examinations revealed orbital emphysema, optic nerve transection, pneumocephalus, and subcutaneous emphysema in the face, neck, shoulder, and mediastinum. Canalicular injury repair was performed, and the emphysema resolved. However, there was near-complete vision loss in the patient's left eye. Because most optic nerve transections occur after a severe disruption in bone structure, pure optic nerve transections without any injury of the bone structure, as in the present case, is extremely rare.

PURPOSE: To evaluate a role as over 35 years, maternal serum markers, and a false positive screen for Down syndrome were the predictor of adverse pregnancy outcome. Materials and METHODS: From Mar.1994, through Feb.1996, 5284 women were screened triple test to detect Down syndrome in the second trimester and were delivered Samsung Cheil hospital. The values of each maternal serum markers were measured with radioimmunoassay. And then, the screen positive of Down syndrome was calculated using alpha-software Version 4.0. The adverse outcome of the fetus and the mother included low birth weight(LBW) ( <2500gm), prematurity( <37 gestational weeks), placenta previa, preterm premature rupture of membranes(PPROM), pregnancy induced hypertension(PIH),abruptio placenta, and intrauterine fetal death(IUFD). The predictor markers included over 35years, elevated alpha-fetoprotein (AFP), elevated human chorionic gonadotropin(hCG), lowered unconjugated estriol (uE3), and a false positive screen for Down syndrome. RESULTS: Mean age and mean gestational weeks in the study were 30+/-4.8 years and 17.1 weeks respectively. The adverse pregnancy outcomes were 357 LBW(6.8%), 253 prematurity(4.8%), 108 placenta previa(2.0%), 68 PPROM(1.3%), 66 PIH(1.3%), 24 abruptio placenta(0.5%), and 20 IUFD(0.4%). In univariate analysis, over 35 years was significantly associated with abruptio placenta, prematurity, and placenta previa, elevated MS-AFP( >2.0 MoM) associated with IUFD, LBW, PIH, prematurity, and PPROM , elevated MS-hCG (>3.0 MoM) associated with IUFD, LBW, PIH, prematurity, and placenta previa, lowered uE3 (<0.75) associated with IUFD, abruptio placenta, LBW, and prematurity.(P <0.05). In multivariate logistic regression analysis, IUFD was significantly associated with only elevated MS-AFP, LBW associated with elevated MS-AFP, elevated MS-hCG, and lowered uE3, PIH associated with only elevated MS-AFP, PPROM only elevated MS-AFP, prematurity only elevated MS-AFP, and placenta previa over 35 years, elevated MS-hCG.(P <0.05). However, abruptio placenta was not significantly associated with predictor markers.(P >0.05) CONCLUSIONS: Some predictors such as over 35 year, elevated hCG, lowered uE3, a false positive screen for Down syndrome were significantly associated with adverse pregnancy outcome. Also in multivariate analysis, we identified especially elevated AFP to be the most reliable predictor for adverse pregnancy outcome.

Osteoporosis is a major health-care problem for aging communities. And postmenopausal osteoporosis is a common disorder characterized by an increase in bone resorption relative to bone formation, generally in conjunction with an increased rate of bone turnover. Twenty female rats were used as rat model of osteoporosis. They randomly were divided into two groups: a normal control group, and calcium-free diet groups treated with bilateral ovariectomy. The animals were sacrified at 12 weeks after treatment. In the rats with osteoporosis, there was significant thining and loss of trabeculae, accompanied by a disconnection of trabeculae. And acid mucopolysaccharides were decreased in osteoporotic animals. In order to setup conditions of invivo micro-CT, proper anesthetic is ketamine (50 mg/kg) /xylazine (6 mg/kg). And proper breathing rate of experimental animals is 1.3~1.6/sec. Our finding suggest that bilateral ovariectomy and calcium-free diet induce decrease in thickeness of trabecular bone and decrease in acid mucopolysaccharide, therefore cause weakness of bone. And micro-CT imaging system is useful to evaluate trabecular bone. Anesthetic time, anesthetics and respiration rate also signify much in micro-CT imaging system.

The vesicoureteral reflux (VUR) is frequently found among the patients with urinary tract infection (UIT) and some patients with VUR progress to reflux nephropathy. The presence of scarring at UIT is an important determinant in the selection of those at risk of progressive damage. 99m Technetium dimercaptosuccinic acid (99m Tc-DMSA) is a renal scanning agent provides a good quality of renal image as a result of preferential cortical accumulation. 99m Tc-DMSA scan and VCUG were performed in 133 patients diagnosed UTI at pediatric department of Kyung Hee University, College of Medicine from May, 1990 to May, 1992 The results were as follows: 1) VUR was seen in 27 children among 133 patients with UTI. The incidence was 20.3%. Under 1 year of age, male to female ratio was higher incidence of VUR. 2) Incidence of renal scarring was higher in patients with VUR than those of without VUR. 3) Grading of VUR in relation to age, the older the age, the lower the grade. 4) There is no correlation between renal scarring and grades of VUR. 5) In distribution of renal scarring, it was found to have tendency to develop at upper polar area, there was diffuse and multiple in patients with VUR. In conclusion the incidence of renal scarring was related to the age of onset, duration of UTI and the severity of the VUR and 99mTc-DMSA scan is mandatory in patient with UTI even without VUR in order to detect early phase of renal scarring.
