RESUMO
Background@#Ear cartilage is a preferred graft material in rhinoplasty. However, after harvest, instability of the auricular framework may arise as a form of donor site morbidity. In the harvest of ear cartilage, the posterior auricular ligament (PAL) is usually sacrificed in order to obtain as much cartilage as possible. Since damage to the PAL may cause auricular instability, we studied the periauricular anatomy using cadavers and evaluated auricular stability during surgery. @*Methods@#Six ears from hemifacial cadavers were studied to clarify the exact anatomy of the PAL. Then, the recoil force of the auricle was serially measured to evaluate the stability of the auricular framework in 30 patients during surgery: before making the skin incision (M1), before and after cutting the PAL (M2, M3), and after harvesting the cymba concha (M4). The differences in force observed after cutting the PAL (ΔM2–M3) and after harvesting the cymba concha (ΔM3–M4) were statistically analyzed. @*Results@#In the cadaveric study, the PAL was identified between the superficial and deep mastoid fasciae and connected the caudal aspect of the cymba concha to the deep mastoid fascia. During surgery, the PAL accounted for 16.20% of the total auricular recoil force. The recoil force decreased by 13.61 N and 11.25 N after cutting the PAL and harvesting the cymba concha, respectively. These decreases were statistically significant (P<0.05). @*Conclusions@#The results suggest that the PAL is a supporting structure of the auricle. Therefore, to preserve auricular stability, minimizing damage to the PAL while harvesting the ear cartilage may be helpful.
RESUMO
Background@#Due to the anatomical complexity of the deep temporal fascia (DTF), practical guidelines for its safe harvest are lacking. However, since the upper temporal compartment (UTC) contains no vital structures, it may provide safe access for DTF harvest. This study aimed to identify the anatomical structures of the temporal compartment in Asian cadavers and to measure their dimensions to enable safe DTF harvest. @*Methods@#The anatomical structures surrounding the temporal compartment were identified in 27 hemifaces from 15 Korean cadavers. After dissection, digital images were acquired and craniometric landmarks were placed upon them to identify the boundaries of the temporal compartment. The horizontal and vertical lengths of the temporal compartment were measured and their surface areas were computationally assessed. Subsequently, differences in the results by sex were evaluated. @*Results@#The five-layer anatomical structure of the UTC was clearly visualized. The UTC was bounded by the temporal septa superiorly and inferiorly, the innominate fascia laterally, and the DTF medially. No vital structures were present within the UTC. The vertical and horizontal lengths of the UTC were 6.41±0.67 cm and 10.44±0.83 cm, respectively, and the surface area of the UTC was 48.52±5.65 cm2. No statistically significant differences were observed in any dimensions between male and female patients. @*Conclusions@#During rhinoplasty, DTF can be harvested as an autologous graft material from the UTC. An anatomical understanding of the UTC will aid in the safe and simple harvest of a sufficient amount of DTF.
RESUMO
BACKGROUND/OBJECTIVES: The doubly labeled water (DLW) method is considered the gold standard for the measurement of total energy expenditure (TEE), which serves to estimate energy requirements. This study evaluated the accuracy of predictive dietary reference intake (DRI) equations for determining the estimated energy requirements (EER) of Korean adults by using the DLW as a reference method. SUBJECTS/METHODS: Seventy-one participants (35 men and 36 women) aged between 20 and 49 years were included in the study. The subjects' EER, calculated by using the DRI equation (EER(DRI)), was compared with their TEE measured by the DLW method (TEE(DLW)). RESULTS: The DRI equations for EER underestimated TEE by -36.3 kcal/day (-1.3%) in men and -104.5 kcal/day (-4.9%) in women. The percentages of accurate predictions among subjects were 77.1% in men and 62.9% in women. There was a strong linear correlation between EER(DRI) and TEE(DLW) (r=0.783, P<0.001 in men and r=0.810, P<0.001 in women). CONCLUSIONS: The present study supports the use of DRI prediction equations to determine EER in Korean adults. More studies are needed to confirm our results and to assess the validity of these equations in other population groups, including children, adolescents, and older adults.

BACKGROUND/AIMS: Percutaneous coronary intervention (PCI) is the standard method of treating ST-segment elevation myocardial infarction (STEMI). There is continuing uncertainty as to whether reducing the thrombus burden through catheter aspiration improves the arrhythmogenic structure of the myocardium in STEMI. We compared the changes in electrical instability after thrombus aspiration-assisted primary PCI using conventional primary PCI. METHODS: The study population included 170 consecutive patients with STEMI who underwent primary PCI. The patients were divided into 80 patients who underwent primary PCI only and 90 patients who underwent thrombus aspiration before PCI. The signal-averaged ECG (SAECG) was obtained 5 +/- 2 days after the intervention. RESULTS: There were no significant differences between the groups in terms of sex, age, cardiovascular risk factors, or time from the onset of symptoms to treatment. The duration of the low amplitude signals less than 40 microV (LAS40), duration of the QRS complex (QRSD), and root mean square voltage of the terminal 40 ms of the QRS complex (RMS40) did not differ between the thrombus aspiration and no thrombus aspiration groups. The incidences of QRSD > 114 ms and RMS40 38 ms was significantly higher in the non-thrombus aspiration group (18 vs. 8, p = 0.018). CONCLUSIONS: Among random patients with STEMI, thrombus aspiration improved all of the parameters of SAECG, which is related to ventricular arrhythmogenesis, although the long-term clinical outcomes need to be assessed.

OBJECTIVES: This study was conducted to investigate the relationships among job stress, job satisfaction, and mental health in marine officers. METHODS: The researchers gathered data on marine officers working at a harbor in Chungcheong Province, South Korea, using a self-reported questionnaire. Mental health was measured by the Symptom Checklist-90-Revision (SCL-90-R), and general characteristics including socioeconomic factors, job stress, and job satisfaction were measured by structured questionnaires. Multiple regression analysis was performed to investigate the relationships among job stress, job satisfaction, and mental health status according to the symptom dimensions of the SCL-90-R. RESULTS: Among the marine officers, obsessive-compulsive behavior, depression, and somatization were the most problematic symptoms. Those who reported poor health, low job satisfaction, and high job stress had a higher prevalence of psychoticism, somatization, depression, anxiety, and phobic anxiety. CONCLUSIONS: An occupational health system should be introduced that would regularly check the mental health of marine officers in charge of ships and sailors, in order to help reduce their stress levels, enhance their job satisfaction, and thereby improve their mental health.

BACKGROUND AND OBJECTIVES: Optimal international normalized ratio (INR) in elderly atrial fibrillation (AF) patients at higher risk of hemorrhagic events remains unclear. We investigated the efficacy and safety of low-intensity warfarin therapy (target international normalized ratio [INR], 1.6-2.6) in elderly Korean patients with nonvalvular AF (NVAF). SUBJECTS AND METHODS: We enrolled 528 NVAF patients (mean age, 67±9 years; 361 men) who were actively taking warfarin. Major events were defined based on the annual rates of ischemic stroke, systemic embolism, and major bleeding events requiring blood transfusion or hospitalization. Time in therapeutic range (TTR) was 45±19% for all patients. RESULTS: Ischemic stroke and systemic embolism occurred in 20 patients with INR between 1.00 and 2.44 (16 ischemic strokes and 4 systemic embolisms) and major bleeding in 37 patients with INR between 1.74 and no coagulation (exceed laboratory detection capability, more than 10 [7 intracranial hemorrhages, 21 gastrointestinal bleedings, and 9 others]). Incidence rates of ischemic or hemorrhagic events at INR3 were 3.0%, 1.4%, and 20.1% per year, respectively. In patients who were ≥70 years old, CHADS₂, CHA₂DS₂VASc, and HAS-BLED scores were significantly higher compared with those in patients who were <70 years old. When we applied the INR between 1.6 and 2.6, as recommended by the Japanese AF Guideline for patients≥70 years old, the TTR increased from 43.8% to 58.6%. In addition, ischemic or hemorrhagic event rates decreased from 1.9% to 1.2% within the optimal INR range. CONCLUSION: Low-intensity warfarin therapy (INR, 1.6-2.6) should be considered in elderly Korean patients with NVAF.

PURPOSE: There is a lack of data on the energy cost of children's everyday activities, adult values are often used as surrogates. In addition, the influence of body weight on the energy cost of activity when expressed as metabolic equivalents (METs) has not been vigorously explored. METHODS: In this study 20 elementary school students 9~12 years of age completed 18 various physical activities while energy expenditure was measured continuously using a portable telemetry gas exchange system (K4b2, Cosmed, Rome, Italy). RESULTS: The average age was 10.4 years and the average height and weight was 145.1 cm and 43.6 kg, respectively. Oxygen consumption (VO2), energy expenditure and METs at the time of resting of the subjects were 5.41 mL/kg/min, 1.44 kcal/kg/h, and 1.5 METs, respectively. METs values by 18 physical activities were as follows: Homework and reading books (1.6 METs), playing game with a mobile phone or video while sitting (1.6 METs), watching TV while sitting on a comfortable chair (1.7 METs), playing video game or mobile phone game while standing (1.9 METs), sweeping a room with a broom (2.7 METs) and playing a board game (2.8 METs) belong to light intensity physical activities. By contrary, speedy walking and running were 6.6 and 6.7 METs, respectively, which belong to high intensity physical activities over 6.0 METs. When the effect of body weight on physical activity energy expenditure was determined, R2 values increased with 0.116 (playing a game at sitting), 0.176 (climbing up and down stairs), 0.246 (slow walking), and 0.455 (running), which showed that higher activity intensity increased explanation power of body weight on METs value. CONCLUSION: This study is important for direct evaluation of energy expenditure by physical activities of children, and it could be used directly for revising and complementing the existing activity classification table to fit for children.

BACKGROUND: Pincer nail deformity is a transverse overcurvature of the nail. This study aimed to define the anatomical characteristics of pincer nail deformity and to evaluate the surgical outcomes. METHODS: A retrospective review was conducted on 20 cases of pincer nail deformity of the great toe. Thirty subjects without pincer nail deformity or history of trauma of the feet were selected as the control group. Width and height indices were calculated, and interphalangeal angles and base widths of the distal phalanx were measured with radiography. We chose the surgical treatment methods considering perfusion-related factors such as age, diabetes mellitus, kidney disease, and peripheral vascular disease. The zigzag nail bed flap method (n=9) and the inverted T incision method (n=11) were used to repair deformities. The outcomes were evaluated 6 months after surgery. RESULTS: The interphalangeal angle was significantly greater in the preoperative patient group (14.0degrees+/-3.6degrees) than in the control group (7.9degrees+/-3.0degrees) (P<0.05). The postoperative width and height indices were very close to the measurements in the control group, and most patients were satisfied with the outcomes. CONCLUSIONS: We believe that the width and height indices are useful for evaluating the deformity and outcomes of surgical treatments. We used two different surgical methods for the two patient groups with respect to the perfusion-related factors and found that the outcomes were all satisfactory. Consequently, we recommend taking into consideration the circulatory condition of the foot when deciding upon the surgical method for pincer nail deformity.

BACKGROUND/OBJECTIVES: Athletes generally desire changes in body composition in order to enhance their athletic performance. Often, athletes will practice chronic energy restrictions to attain body composition changes, altering their energy needs. Prediction of resting metabolic rates (RMR) is important in helping to determine an athlete's energy expenditure. This study compared measured RMR of athletic and non-athletic adolescents with predicted RMR from commonly used prediction equations to identify the most accurate equation applicable for adolescent athletes. SUBJECTS/METHODS: A total of 50 athletes (mean age of 16.6 +/- 1.0 years, 30 males and 20 females) and 50 non-athletes (mean age of 16.5 +/- 0.5 years, 30 males and 20 females) were enrolled in the study. The RMR of subjects was measured using indirect calorimetry. The accuracy of 11 RMR prediction equations was evaluated for bias, Pearson's correlation coefficient, and Bland-Altman analysis. RESULTS: Until more accurate prediction equations are developed, our findings recommend using the formulas by Cunningham (-29.8 kcal/day, limits of agreement -318.7 and +259.1 kcal/day) and Park (-0.842 kcal/day, limits of agreement -198.9 and +196.9 kcal/day) for prediction of RMR when studying male adolescent athletes. Among the new prediction formulas reviewed, the formula included in the fat-free mass as a variable [RMR = 730.4 + 15 x fat-free mass] is paramount when examining athletes. CONCLUSIONS: The RMR prediction equation developed in this study is better in assessing the resting metabolic rate of Korean athletic adolescents.

BACKGROUND: It is not well known about the implication of left ventricular (LV) strain as a predictor for mortality in patients with chronic aortic regurgitation (AR). The purpose of this study was to investigate whether global longitudinal strain measured by two-dimensional speckle-tracking echocardiography could predict long-term outcome in patients with chronic AR. METHODS: This is a single center non-randomized retrospective observational study. The patients with chronic AR from January 2002 to December 2012 were retrospectively enrolled. Following patients were excluded; combined other significant valvular disease, previous heart surgery, aortic disease, congenital heart disease, acute AR and young age under 18 years old. Finally, 60 patients were analyzed and the LV global strain rate was measured on apical four chamber image (GS-4CH). RESULTS: During 64 months follow-up duration, 16 patients (26.7%) were deceased and 38 patients (63.3%) underwent aortic valve replacement (AVR). Deceased group was older (69 years old vs. 51 years old, p < 0.001) and had lower longitudinal strain (-12.05 +/- 3.72% vs. -15.66 +/- 4.35%, p = 0.005). Kaplan-Meier survival curve stratified by GS-4CH showed a trend of different event rate (log rank p = 0.001). On multivariate analysis by cox proportional hazard model adjusting for age, sex, body surface area, history of atrial fibrillation, blood urea nitrogen, LV dilatation, LV ejection fraction and AVR, decreased GS-4CH proved to be an independent predictor of mortality in patients with chronic AR (hazard ratio 1.313, 95% confidence interval 1.010-1.706, p = 0.042). CONCLUSION: GS-4CH may be a useful predictor of mortality in patient with chronic AR.

Cardiac involvement is a major cause of morbidity and mortality in hypereosinophilic syndrome (HES). It is classified into 3 stages by the degree of eosinophils-mediated heart injury; acute necrotic stage, thrombotic stage, and fibrotic stage. Nonetheless, definitive evidence that each patient passes sequentially through these stages is lacking. We present a case of 48-year-old male patient with dyspnea and peripheral edema who underwent valve replacement surgery due to severe mitral regurgitation. After the valve replacement, HES with cardiac involvement in the thrombotic stage was diagnosed. In the follow-up study, the patient progressed into fibrotic stage of HES.

PURPOSE: Reconstruction for post-radiation scar on periorbital area including upper eyelid takes consider of eyelid function and cosmetic results. It is a challenging procedure to reconstruct the severe radiation induced scars deformities on face around the orbital area in terms of its complicated anatomy and restoration of cosmetic social function. The authors report a reconstruction case of radiation induced severe facial deformities with scars including upper lid and periorbital area using evidence based plastic surgical techniques such as newly designed lower lid orbicularis oculi myocutaneous transposition flap, lateral canthopexy, skin graft, composite graft, fat graft, acellular dermal matrix graft, Z-plasty focusing on cosmetic and functional result. METHODS: A 18 year-old female patient had right upper facial deformities caused by radiation induced wide scars around the right periorbital, upper lid and temporal area after treatment for hemangioma at age of 1. She also showed right facial palsy on forehead, and hypoplasia of left ala nasi. The patient suffered from skin atrophy, wide scar formation, scar contractures on right periorbital area, severe lagophthalmos on right eye, right frontal facial palsy, and small hypoplastic left ala nasi. At the first operation, release of scars and full thickness skin graft, reposition of asymmetric right eyebrow caused by facial palsy using Z-plasty, correction of temporal depression using acellular dermal matrix (AlloDerm(R)) graft, and auricular composite graft for left ala nasi reconstruction were performed. And after 4 months follow-up, the second operations were performed including lower orbicularis oculi muscle transposition flap for upper lid lagophthalmos, lateral canthopexy, and fat graft. RESULTS: Lower lid orbicularis oculi muscle transposition flap and all grafts were successfully survived. After 3 weeks follow-up, she showed good looking facial appearance and facial symmetry, and there were no complications. CONCLUSION: For post-radiation facial scar reconstruction, it showed a better cosmetic outcome using flap transfer rather than skin graft. The newly designed lower eyelid orbicularis oculi muscle transposition flap, canthopexy, fat graft give a good result for reconstruction of radiation induced scars of upper eyelid and periorbital deformities.

BACKGROUND: The septal cartilage is the most useful donor site for autologous cartilage graft material in rhinoplasty. For successful nasal surgery, it is necessary to understand the developmental process of the nasal septum and to predict the amount of harvestable septal cartilage before surgery. METHODS: One hundred twenty-three Korean patients who underwent three-dimensional (3D) facial bone computed tomography (CT) were selected for evaluation of the midsagittal view of the nasal septum. Multiple parameters such as the area of each component of the nasal septum and the amount of harvestable septal cartilage were measured using Digimizer software. RESULTS: The area of the total nasal septum showed rapid growth until the teenage years, but thereafter no significant change throughout the lifetime. However, the development of the septal cartilage showed a gradual decline due to ossification changes with aging after puberty in spite of a lack of change in the total septal area. The area of harvestable septal cartilage in young adults was 549.84+/-151.26 mm2 and decreased thereafter with age. CONCLUSIONS: A 3D facial bone CT scan can provide valuable information on the septal cartilage graft before rhinoplasty. Considering the developmental process of the septal cartilage identified in this study, septal surgery should not be performed until puberty due to the risk of nasal growth impairment. Furthermore, in elderly patients who show a decreased cartilage area due to ossification changes, septal cartilage harvesting should be performed carefully due to the risk of saddle nose deformity.

This study aims to investigate the association between muscle strength and fear of falling in Korean elderly. The study used data obtained by interview and physical test, targeting a total of 339 people 65 years old and over. In order to analyze the relationship between muscle strength and fear of falling we performed a logistic regression analysis to calculate odds ratio and 95% confidence interval after adjustments body mass index, smoking status, drinking status, cohabitation status, self-rated health, self-rated sight, cardiovascular disease and cancer status, history of falls. The levels of statistically significance were set at p<0.05. Through the logistic regression analysis, we found that the male elders who has high level of upper extremity strength and lower extremity strength appeared to have a significantly lower fear of falling than those who didn't. In addition, the female who has high level of lower extremity strength appeared to have a significantly lower fear of falling than those who didn't. This research results show a correlation between level of strength and fear of falling.

Autochthonous human gnathostomiasis had never been reported in the Republic of Korea. We report here a case of Gnathostoma spinigerum infection in a 32-year-old Korean woman, presumed to have been infected via an indigenous route. The patient had experienced a painful migratory swelling near the left nasolabial fold area of the face for a year, with movement of the swelling to the mucosal area of the upper lip 2 weeks before surgical removal of the lesion. Histopathological examinations of the extracted tissue revealed inflammation with heavy eosinophilic infiltrations and sections of a nematode suggestive of a Gnathostoma sp. larva. The larva characteristically revealed about 25 intestinal cells with multiple (3-6) nuclei in each intestinal cell consistent with the 3rd-stage larva of G. spinigerum. The patient did not have any special history of travel abroad except a recent trip, 4 months before surgery, to China where she ate only cooked food. The patient is the first recorded autochthonous case of G. spinigerum infection in Korea.

Weight-controlling can be supported by a proper prescription of energy intake. The individual energy requirement is usually determined through resting energy expenditure (REE) and physical activity. Because REE contributes to 60-70% of daily energy expenditure, the assessment of REE is very important. REE is often predicted using various equations, which are usually based on the body weight, height, age, gender, and so on. The aim of this study is to validate the published predictive equations for resting energy expenditure in 76 normal weight and 52 obese Korean children and adolescents in the 7-18 years old age group. The open-circuit indirect calorimetry using a ventilated hood system was used to measure REE. Sixteen REE predictive equations were included, which were based on weight and/or height of children and adolescents, or which were commonly used in clinical settings despite its use based on adults. The accuracy of the equations was evaluated on bias, RMSPE, and percentage of accurate prediction. The means of age and height were not significantly different among the groups. Weight and BMI were significantly higher in obese group (64.0 kg, 25.9 kg/m2) than in the non-obese group (44.8 kg, 19.0 kg/m2). For the obese group, the Molnar, Mifflin, Liu, and Harris-Benedict equations provided the accurate predictions of > 70% (87%, 79% 77%, and 73%, respectively). On the other hand, for non-obese group, only the Molnar equation had a high level of accuracy (bias of 0.6%, RMSPE of 90.4 kcal/d, and accurate prediction of 72%). The accurate prediction of the Schofield (W/WH), WHO (W/WH), and Henry (W/WH) equations was less than 60% for all groups. Our results showed that the Molnar equation appears to be the most accurate and precise for both the non-obese and the obese groups. This equation might be useful for clinical professionals when calculating energy needs in Korean children and adolescents.
