PURPOSE: It is difficult to objectively evaluate the outcomes of plastic surgical procedures. The combination of aesthetic and medical factors makes outcome quantification difficult. In this study, fracture reduction accuracy was objectively evaluated in patients with zygomatic complex fractures. Patients satisfaction with the accuracy was also examined. In addition, the patients' overall satisfaction and discomfort due to complications were analyzed. METHODS: Eighty-five patients who had surgeries via bicoronal incision for zygomatic complex fracture from March 2006 to December 2009 were included in this study. Two plastic surgeons evaluated the accuracy of the fracture reduction with postoperative computed tomography. A survey questionnaire was administered to evaluate the patients' overall satisfaction and the impact of symptoms associated with the procedure on the patients' daily lives. RESULTS: The overall patient satisfaction rate was 82.1 +/- 10.9% (range, 45~100%). The level of deformation was 6.7 +/- 10.9%, the levels of discomfort in daily life due to pain, paresthesia, scar, and facial palsy were 8.5 +/- 13.2%, 5.8 +/- 8.9%, 4.4 +/- 9.9%, and 1.9 +/- 9.2%, respectively. According to the visual analogue scale, paresthesia was found to be the most frequent symptom (43.5%), and pain was the most troublesome symptom. CONCLUSION: The use of bicoronal incision for treating zygomatic complex fractures can cause various complications due to wide incision and dissection. However, this technique can provide optimized reduction and rigid fixation. Most of these postoperative complications can cause significant discomfort in the patient. It is thought that the use of correct surgical technique and the accurate knowledge of craniofacial anatomy will result in a reduction of complications and significantly increase patient satisfaction.

BACKGROUND: Health problems in shift workers vary including obesity acting as a risk factor in cerebrovascular diseases. Recent studies have commonly determined the prevalence of obesity in shift workers on the basis of body mass index. The accuracy of BMI for diagnosing obesity are still limited apparently. Consequently, this study aimed to determine the relationship between shift work and obesity according to the total body fat percentage in Korean wage workers. METHODS: From the Fourth and the Fifth Korea National Health and Nutrition Examination Survey (2008-2011), after military personnel were excluded, a total of 2952 wage workers (20 < or = age < or = 65) whose current jobs were their longest jobs were selected as subjects of the study. The total body fat percentage was used to determine the obesity standards (> or =25.7 % in males and > or =36.0 % in females). The subjects were divided into groups by gender and work type (manual vs non-manual), and chi-squared test was used to evaluate the relationship between socio-economic, health behavior, and work-related factors, on the one hand, and obesity, on the other. In addition, multivariate logistic regression analysis was performed to examine the effects of shift work on obesity. RESULTS: When other factors were controlled for, the risk of obesity in shift work showed a statistically significant increase (odds ratio = 1.779, 95 % confidence interval = 1.050-3.015) in the male manual worker group. However, there were no significant results in the male non-manual and female worker groups. CONCLUSION: Shift work was related to a higher risk of obesity in the Korean male manual worker group.

BACKGROUND: In modern society, many workers are stressed. Supervisors' support or behavior can affect the emotional or psychological part of the worker. The purpose of this study is to investigate the effect of supervisor's behavior on worker's stress. METHODS: The study included 19,272 subjects following the assignment of weighted values to workers other than soldiers using data from the Fourth Korean Working Condition Survey. Supervisors' behavior was measured using 5 items: “supervisor feedback regarding work,”“respectful attitude,”“good conflict-resolution ability,”“good work-related planning and organizational ability,” and the encouragement of participation in important decision making. Job stress was measured using 1 item: “I experience stress at work.” Multiple logistic regression analysis was performed to examine the effects of supervisors' behavioral, general, occupational, and psychosocial characteristics on job stress in workers. Organizational characteristics associated with supervisors' behavior were also analyzed. RESULTS: The results showed that supervisors' provision of feedback regarding work increased workers' job stress (OR = 1.329, 95% CI = 1.203 ~ 1.468). When a supervisor respect workers (OR = 0.812, 95% CI = 0.722 ~ 0.913) or good at planning and organizing works (OR = 0.816, 95% CI: 0.732 ~ 0.910), workers' job stress decreased. In particular, the two types of supervisor behaviors, other than feedback regarding work, were high in private-sector organizations employing less than 300 employees. CONCLUSION: Supervisors' behavior influenced job stress levels in workers. Therefore, it is necessary to increase education regarding the effects of supervisors' behavior on job stress, which should initially be provided in private-sector organizations with up to 300 employees.

4.Underwater and Hyperbaric Medicine as a Branch of Occupational and Environmental Medicine.
Annals of Occupational and Environmental Medicine 2013;25(1):39-
Exposure to the underwater environment for occupational or recreational purposes is increasing. As estimated, there are around 7 million divers active worldwide and 300,000 more divers in Korea. The underwater and hyperbaric environment presents a number of risks to the diver. Injuries from these hazards include barotrauma, decompression sickness, toxic effects of hyperbaric gases, drowning, hypothermia, and dangerous marine animals. For these reasons, primary care physicians should understand diving related injuries and assessment of fitness to dive. However, most Korean physicians are unfamiliar with underwater and hyperbaric medicine (UHM) in spite of scientific and practical values. From occupational and environmental medicine (OEM) specialist's perspective, we believe that UHM should be a branch of OEM because OEM is an area of medicine that deals with injuries caused by physical and biological hazards, clinical toxicology, occupational diseases, and assessment of fitness to work. To extend our knowledge about UHM, this article will review and update on UHM including barotrauma, decompression illness, toxicity of diving gases and fitness for diving.

BACKGROUND: The glycemic control in diabetes is well known to arouse a medical risk of macrovascular regions. This study aimed for exploring the relationship between carotid artery intima media thickness (IMT) and the risk triggers of macrovascular diseases in the group of glycated hemoglobin value less than 6.5%. METHODS: The subjects were made of 336 health-check examinees in a university hospital and tested by glycated hemoglobin (HbA1c) including ultrasound application on carotid artery IMT to be measured. The relationship between values of HbA1c and carotid artery IMT was reviewed by use of Pearson's correlation, and then influential causes on the carotid artery IMT were analyzed with multiple linear regression models. RESULTS: Elements like age and fasting plasma glucose were associated with the carotid artery IMT in both men and women. HbA1c, C-reactive protein (CRP) in men and waist to hip ratio (WHR), high-density lipoprotein (HDL)-cholesterol in women showed statistically significant association with the carotid artery IMT. Age and HbA1c were recognized as variables affecting on the carotid artery IMT in men, in contrast, age was only a significant affecting factor in women with regarding various considerations such as fasting plasma glucose, CRP, HDL, WHR and smoking. CONCLUSIONS: Our clinical investigation revealed that HbA1c was associated with the carotid artery IMT in normal and pre-diabetes with HbA1c less than 6.5%. The outcome might suggest preliminary glucose control be monitored and managed in order to detect and regulate the impairment of macrovascular diseases prior to the occurrence of diabetes.

PURPOSE:
The concurrent regimen of docetaxel, doxorubicin, and cyclophosphamide (TAC) has been categorized as a high-risk factor for febrile neutropenia (FN). The incidence of FN was reported to be as high as 17%–26% in studies conducted in Western countries. However, these rates may vary among different ethnic groups. This study aimed to evaluate the incidence of FN and its effect on prognosis following adjuvant TAC chemotherapy in Korean patients with advanced breast cancer.
METHODS:
We analyzed data from 187 patients who received 6 cycles of adjuvant TAC chemotherapy between July 2005 and December 2014. No patients received long-acting granulocyte-colony stimulating factor (G-CSF) as primary prophylaxis for FN due to guidelines for cost reimbursement in Korea. The incidence rates of FN, dose reduction of TAC, relative dose intensity (RDI), relapse-free survival (RFS), and overall survival (OS) were investigated.
RESULTS:
A total of 102 (54.5%) patients experienced FN, especially older patients (51 years vs. 49 years, p=0.045). RDI was lower in patients with FN than in those without (96.4% vs. 99.5%, p=0.001, respectively). Death was reported in 2 patients (2.35%) without FN and in 10 patients (9.80%) with FN (hazard ratio [HR]: 6.64; 95% confidence interval [CI]: 1.28 to 34.36; p=0.024). No significant differences in RFS (p=0.235) were found using Kaplan-Meier analysis.
CONCLUSION
The incidence of FN was significantly higher in Korea than in Western countries, and FN had a negative impact on the patients' prognosis. Primary prophylactic G-CSF should be prioritized in Korean patients with advanced breast cancer who receive adjuvant TAC chemotherapy.

Background:
Corrective osteotomy is an effective surgery for correcting posture in patients with ankylosing spondylitis (AS). Despite satisfactory correction, some patients experience re-stooping during follow-up. However, there have been no studies on restooping in AS. We aimed to analyze the factors that affect re-stooping.
Methods:
Fifty patients (50 cases) who underwent thoracolumbar corrective osteotomy for AS from March 2006 to April 2018 were analyzed. We defined re-stooping as global kyphosis that recurs after corrective osteotomy. The patients were divided into two groups based on the ratio of correction loss: non-re-stooping group (N group) and re-stooping group (R group). We analyzed the demographic data and radiological parameters, such as modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), sagittal vertical axis, and various angles. We also investigated the factors affecting re-stooping by analyzing the correlation between the ratio of correction loss and various factors.
Results:
A significant difference was seen in the change in the mSASSS from before surgery to the last follow-up between the N group (2.87 ± 3.08) and the R group (9.20 ± 5.44). In multivariate analysis, only the change in the mSASSS from before surgery to the last follow-up was significantly correlated with the ratio of correction loss.
Conclusions
Thoracolumbar corrective osteotomy seems to provide high satisfaction among patients with AS but can lead to re-stooping during follow-up. The change in mSASSS was related with re-stooping in the current study. We recommend active rehabilitative exercises and appropriate medication depending on the patient’s condition, which may help delay the postoperative progression of AS.

PURPOSE:
The 8th edition of the American Joint Committee on Cancer (AJCC) staging manual introduced a new prognostic staging system for breast cancer. This study aimed to evaluate the changes in staging distribution and predictive power of the new staging system.
METHODS:
Of the 12,275 patients with breast cancer identified from the Severance Breast Cancer Registry who underwent surgery between 1978 and 2016, 12,125 patients met the inclusion criteria.
RESULTS:
In both the 7th and 8th staging systems, stage I patients constituted the largest proportion (38.2% and 48.4%). Migration from the 7th to 8th edition of the AJCC manual resulted in a decrease in stage II population and an increase in stage I and III populations. A total of 1,293 (15.4%) patients were upstaged, and 1,201 (14.3%) were downstaged. Downstaged patients had better recurrence-free and overall survival (p < 0.001). Pathologic complete response after neoadjuvant therapy showed good prognosis as p stage 0, and yp stages I and III showed poorer outcomes than the same p stage (p < 0.001).
CONCLUSIONS
Staging migrations are common in early breast cancer under the prognostic staging system. The prognostic staging system of the 8th edition of the AJCC manual discriminates survival outcomes better than the anatomical staging system of the 7th edition of the AJCC manual.

Background:
Riehl’s melanosis of the face and neck has been reported in middle-aged women who have darker skin types. Recently, cases of Riehl’s melanosis have been on the rise in Korea, which might reflect the increased use of various cosmetic products and procedures.
Objective:
This study was designed to analyze the clinicopathological characteristics and treatment outcomes of Riehl’s melanosis in Korean patients.
Methods:
We closely observed 80 patients with Riehl’s melanosis diagnosed in Asan Medical Center and Hanyang University Medical Center between 2005 and 2015. A skin biopsy was analyzed in 51 patients, and a patch test was carried out in 16 patients.
Results:
Patients with chronic Riehl’s melanosis (>12 months) had an increased frequency of previous laser treatments. Patients with acute Riehl’s melanosis (<3 months) reported a previous history of dry skin, itching, or irritation as a result of the use of hair dye. Patients older than 50 years, with darker skin type, and with a longer disease duration (>12 months) had poor response rates. Chronic Riehl’s melanosis may be preceded by repeated irritation of barrier-compromised skin, and acute Riehl’s melanosis seems to be an allergic form of Riehl’s melanosis.
Conclusion
Riehl’s melanosis has different clinical manifestations according to disease duration and different treatment responses based on disease duration.

PURPOSE: This study examined the relationships between early menarche and sexual behaviors among Korean female adolescents. METHODS: We analyzed data from the eighth Korea Youth Risk Behavior Web-based survey that was conducted on female high school students in grades 10-12. The survey included 17,867 students, and 974 students were assigned to the early menarche group because they had experienced menarche when they were in grade four or below, and 16,893 students were assigned to the normal menarche group because they had experienced menarche during or after grade five. The characteristics of the sexual behaviors in the early menarche and normal menarche group were analyzed. RESULTS: The early menarche group was at a higher risk of intersexual kissing or petting (odds ratio [OR], 1.54; 95% confidence interval [CI], 1.28-1.87), intersexual intercourse (OR, 2.35; 95% CI, 1.65-3.36), homosexual kissing or petting (OR, 3.53; 95% CI, 2.22-5.59), homosexual intercourse (OR, 7.70; 95% CI, 4.04-14.66), being the victim (OR, 2.89; 95% CI, 1.98-4.22) or the assailant (OR, 13.55; 95% CI, 6.61-27.78) of sexual assaults, intercourse without any contraception (OR, 1.92; 95% CI, 1.06-3.46), and pregnancy (OR, 5.72; 95% CI, 2.31-14.15) than the normal menarche group. CONCLUSION: Early menarche is associated with risky sexual behaviors among adolescent females; therefore, developing comprehensive sexual health education programs and tools for early intervention are required for children who are expected to experience early menarche.
