OBJECTIVE: The outcome of traumatic cardiac arrests remains poor. Nevertheless, the prehospital treatments for traumatic arrests are insufficient in Korea. This study was conducted to compare the prehospital treatments in traumatic and non-traumatic out-of-hospital cardiac arrests (OHCA). METHODS: This was a retrospective, single-center study based on the prospectively collected database of an academic tertiary medical center. The study period was from 2009 to 2017. The following items were compared: age, sex, rates of bystander cardiopulmonary resuscitation (CPR), prehospital intubation, prehospital defibrillation, prehospital epinephrine administration, CPR duration, rates of return of spontaneous circulation, and the survival discharge. RESULTS: Among 786 arrest patients, there were 226 (28.7%) traumatic cardiac arrests and 560 (71.2%) non-traumatic cardiac arrests. The rate of bystander CPR was lower (3.1% vs. 17.5%, P<0.001) in traumatic OHCAs. The prehospital intubation, defibrillation, and epinephrine administration were lower in traumatic OHCAs. CONCLUSION: The prehospital treatments, including bystander CPR, prehospital intubation, and epinephrine administration, were performed less actively in traumatic OHCAs. On the other hand, these results were limited to a single hospital.

Background: A patient’s overall condition sometimes does not allow for the complete removal of a dead eschar or injured slough in cases involving a pressure-injury skin lesion. This frequently occurs in clinical practice, particularly in bedridden and older patients receiving home care or intensive care. Even after debridement, it is also difficult to manage open exudative wounds in these patients. Nevertheless, when a mature or immature eschar is treated without proper debridement, liquefaction necrosis underneath the eschar or slough tends to reveal a large, open wound with infectious exudates. We hypothesized that if the presence of any bacteria under the eschar can be evaluated and the progression of the presumed infection of the subeschar can be halted or delayed without creating an open wound, the final wound can be small, shallow, and uninfected. Methods: Using a punch instrument, we performed 34 viable subeschar tissue cultures with a secure junction between the eschar and the normal skin. Results: The bacterial study had 29 positive results. Based on these results and the patient’s status, appropriate antibiotics could be selected and administered. The use of suitable antibiotics led to relatively shallow and small exposed wounds. Conclusions This procedure could be used to detect potentially pathogenic bacteria hidden under black or yellow eschars. Since subeschar infections are often accompanied by multidrug-resistant bacteria, the early detection of hidden infections and the use of appropriate antibiotics are expected to be helpful to patients.

The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin B6, phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.

Background/Aims: The prevalence of nonalcoholic fatty liver disease (NAFLD) has increased rapidly as a consequence of more sedentary lifestyles and a Westernized diet. Fracture is a major clinical problem in older people, but few large-scale cohort studies have evaluated the relationship between NAFLD and fracture. Therefore, we aimed to determine whether the fatty liver index (FLI), which represents the severity of NAFLD, can predict fracture risk. Methods: We analyzed the relationship between the FLI and incident fracture using multivariate Cox proportional hazards models and data for 180,519 individuals who underwent National Health check-ups in the Republic of Korea between 2009 and 2014. Results: A total of 2,720 participants (1.5%) were newly diagnosed with fracture during the study period (median 4.6 years). The participants were grouped according to FLI quartiles (Q1, 0 to <5.653; Q2, 5.653 to <15.245; Q3, 15.245 to <37.199; and Q4 ≥37.199). The cumulative fracture incidence was significantly higher in the highest FLI group than in the lowest FLI group (Q4, 986 [2.2%] and Q1, 323 [0.7%]; p<0.001). The adjusted hazard ratio indicated that the highest FLI group was independently associated with a higher incidence of fracture (hazard ratio for Q4 vs Q1, 2.956; 95% confidence interval, 2.606 to 3.351; p<0.001). FLI was significantly associated with a higher incidence of fracture, independent of the baseline characteristics of the participants. Conclusions Our data imply that the higher the FLI of a Korean patient is, the higher their risk of osteoporotic fracture, independent of key confounding factors.

Background: Eye measurements in Koreans have been studied extensively, but researchers have reported widely differing values, even for the same parameters. These discrepancies are likely due to inconsistencies in the proportions of subjects with double eyelids included in their studies. We retrospectively studied eye measurements according to the presence or absence of double eyelids, and compared the results to those of previous studies. Methods: We conducted anthropometric measurements of eyes in young (20–29 years) Korean women with no congenital malformation, trauma, or surgery of the eyelids. The participants were dichotomized according to the presence of double eyelids, resulting in 116 eyes with single eyelids and 124 with double eyelids. We measured the palpebral fissure length (PFL), palpebral fissure height (PFH), margin reflex distance 1 (MRD1), intercanthal distance (ICD), interpupillary distance (IPD), outer canthal distance (OCD), and inclination of the palpebral fissure in each eye. Results: The mean PFL was 24.1 mm in the single-eyelid group and 25.5 mm in the double-eyelid group. The other mean values for the two groups were as follows: PFH, 8.0 mm and 9.9 mm, respectively; MRD1, 2.8 mm and 4.1 mm, respectively; IPD, 61.6 mm and 62.8 mm, respectively; and OCD, 85.3 mm and 87.9 mm, respectively. Conclusions In the double-eyelid group, the horizontal and vertical length of the eye was greater than in the single-eyelid group, and the mean values of IPD, OCD, PFL, PFH, and MRD1 were statistically significantly higher.

BACKGROUND: It is a well known fact that students majoring in medicine and engineering suffer from higher stress level and depression than students in other majors. This study was done to assess the prevalence of depression and the infl uencing factors among the university students majoring in either medicine or engineering and to compare the depression prevalence between the two groups. METHODS: The study randomly selected 640 students either majoring in medicine or engineering from two universities in Kyung-Gi province, Korea. Each of 320 students majoring in either of the two majors from each university was recruited. Among 640 students, 360 students, who were composed of 172 medical students and 188 engineering students was finally chosen for the analysis. The Zung Self-Rating Depression Scale was used to measure the depression state. RESULTS: The average Zung depression score of university students was 49.2 alpha 9.8. Medical students had a higher score of 52.4 alpha 9.3 as compared to engineering students, who scored 46.3 +/- 9.4. Overall depression rate was 42.8%. Medical students had a higher depression rate (52.3%) than engineering students (34.0%). The logistic analysis showed that infl uencing factors on depression state were sex, grade, major, stress and satisfactory sleep. The main source of stress for medical students was the grades from classes whereas job search was for engineering students. There were differences between the two groups in managing the stress. Medical students chose alcohol drinking or smoking for stress management whereas engineering students playing selected video games as their outlet. CONCLUSION: Medical students from urban areas seemed to be depressed more than engineering students. Their stress management methods among the subjects were drinking, smoking, and playing video games which may cause further physical and psychological problems in the future.

BACKGROUND: The presence of enophthalmos is an important determinant in the decision of orbital wall fracture surgery. We proposed eyelid drooping as a new anthropometric diagnostic measure and analyzed whether eyelid drooping is associated with enophthalmos. METHODS: This retrospective study was performed from January 2014 to December 2016. A total of 75 patients with blowout fractures were studied. One experimenter measured the degree of enophthalmos using a Hertel exophthalmometer at 1 week after trauma and at 3 months after surgery. The height change of the upper eyelid was measured using the marginal reflex distance (MRD) on both sides, and the degree of eyelid drooping was calculated by comparing the two lengths. We analyzed statistically the correlation between enophthalmos and eyelid drooping. RESULTS: We found a highly significant correlation between the degree of enophthalmos and the reduction rate of MRD (RRM, as an indicator of eyelid drooping) at 1 week after trauma (r = 0.845). Approximately 2.0 mm of enophthalmos was associated with a 30.8% reduction in MRD on the affected side as compared with the normal side. At 3 months after surgery, patients showed improved eyelid appearance, with a moderate association between enophthalmos and RRM. CONCLUSION: We demonstrated that the degree of enophthalmos, measured using an exophthalmometer, is associated with a change in the height of the upper eyelid. Thus, upper eyelid drooping can be used as another indicator for orbital wall fracture surgery. Compared with conventional methods, measurements of eyelid drooping are easy to perform, offering a great advantage and understanding to the patient.

In general, patients with neurofibromatosis type I have a higher risk than those with other types of neurofibromatosis of developing soft-tissue sarcomas related to the nervous system. We here present a 42-year-old man with neurofibromatosis type I who developed a protruding mass over only 2 weeks. The histopathological diagnosis was epithelioid sarcoma. Epithelioid sarcomas are rare and, to the best of our knowledge, no epithelioid sarcomas have been reported in patients with neurofibromatosis type I. Radical excision of the primary lesion was performed and postoperative radiotherapy and chemotherapy administered, as is recommended for epithelioid sarcoma. Our case emphasizes that patients with neurofibromatosis type I may develop malignant tumors

The presented case is a 43-year-old male with a painless mass in the right neck for two weeks. Excisional biopsy was performed under the clinical impression of malignant lymphoma, because he experienced lymphoma 32 months ago. Histopathologically, it shows hyperplasia of small blood vessels and lymphoid cells with eosinophilic infiltration, so it was diagnosed as Kimura's disease. This seems to be the first reported case of Kimura's disease developed during follow up period after remission of lymphoma.

PURPOSE: We performed invasive thermometry to verify the elevation of local temperature in the liver during hyperthermia. MATERIALS AND METHODS: Three 40-kg pigs were used for the experiments. Under general anesthesia with ultrasonography guidance, two glass fiber-optic sensors were placed in the liver, and one was placed in the peritoneal cavity in front of the liver. Another sensor was placed on the skin surface to assess superficial cooling. Six sessions of hyperthermia were delivered using the Celsius TCS electro-hyperthermia system. The energy delivered was increased from 240 kJ to 507 kJ during the 60-minute sessions. The inter-session cooling periods were at least 30 minutes. The temperature was recorded every 5 minutes by the four sensors during hyperthermia, and the increased temperatures recorded during the consecutive sessions were analyzed. RESULTS: As the animals were anesthetized, the baseline temperature at the start of each session decreased by 1.3degrees C to 2.8degrees C (median, 2.1degrees C). The mean increases in temperature measured by the intrahepatic sensors were 2.42degrees C (95% confidence interval [CI], 1.70-3.13) and 2.67degrees C (95% CI, 2.05-3.28) during the fifth and sixth sessions, respectively. The corresponding values for the intraperitoneal sensor were 2.10degrees C (95% CI, 0.71-3.49) and 2.87degrees C (1.13-4.43), respectively. Conversely, the skin temperature was not increased but rather decreased according to application of the cooling system. CONCLUSION: We observed mean 2.67degrees C and 2.87degrees C increases in temperature at the liver and peritoneal cavity, respectively, during hyperthermia. In vivo real-time thermometry is useful for directly measuring internal temperature during hyperthermia.
