Background : The aim of this study was to confirm the risk factors for low back pain and injury to improve the prevention and treatment of lower back pain. Materials and Methods : An epidemiologic study of low back pain and injury was performed with questionnaires distributed to 471 women working at Yeungnam university hospital. The differences in low back pain and injuries among various hospital departments were analyzed by a one-way analysis of variance (ANOVA), and the relevant factors included in the questionnaire were determined by a factor analysis. Results : The frequency of low back pain in women in the department of diet and in the maintenance department was higher than among the other departments. The frequency of low back pain was mainly related to the frequency of psychosomatic symptoms. In addition, the low back pain was partially related to the frequency of psychosomatic symptoms and partially related to the frequency of pushing during the workday. The degree of disability from low back pain was increased by lifting and hard physical work and was related to the frequency of psychosomatic symptoms and the degree of work dissatisfaction. The frequency of low back injury was increased by increased standing time during work and hard physical work. The frequency of low back injury was related to advancing age and in part to psychosomatic symptoms. Conclusion : Lower back pain and its associated complications are related to psychosomatic factors and type of work. Lower back injury is related to physiological factors such as age. For the prevention and treatment of lower back pain, a multidisciplinary approach is required.

Purpose: The purpose of this study was to investigate the epidemiologic characteristics of patients who visited emergency departments (EDs) after intentional poisoning in Korea. Methods: This study retrospectively analyzed the data of of 23 hospitals during a five-year period, between 2011 and 2015. We included patients who inflicted injury to themselves - attempt of suicide - by means of poisoning. Results: A total of 18,121 patients visited an ED after intentional poisoning. Among them, 58.3% were females; however, there were more males among those aged 60 years or older. The mortality rate for males was 8.6%, which was 3.1 times higher than that for females with 2.8%. The most common poison was pesticides (35.4%) in males and sedative-hypnotics (44.0%) in females. The most common causative agent of death was pesticide in both sexes (75.2% and 65.3%, respectively). Since the production of paraquat was discontinued in 2011, the number of deaths from pesticide poisoning has decreased. The mortality rate declined in both males and females, from 12.6% and 4.5% in 2011 to 7.1% and 2.1% in 2015, respectively. Conclusion: In this study, we analyzed the epidemiologic characteristics of intentional poisoning, especially the frequency of suicide attempts by gender and age group, the cause of suicide, and the causative agent. This can be used as basic data for establishing policies to reduce and prevent suicide attempts by poisoning.

Objectives: The reproductive health of female workers has been extensively investigated in South Korea and other countries worldwide. However, few studies have discussed the reproductive health of male workers. In this study, we reviewed the recent literature that reports on the effects of occupational exposure on the reproductive health of male workers and the health of their children. Methods: In May 2020 we used the PubMed search engine to search the literature over the last 10 years and chose case-control, cohort, and cross-sectional studies and reviews. We selected epidemiological studies that investigated the association between pre-pregnant occupational exposure and the reproductive health of male workers and the health of their children. We excluded case reports, non-epidemiological studies (animal experiments, cellular-level experiments, and similar articles), and studies that described postnatal occupational exposure. Results: We eventually selected 23 studies. The studies that included exclusively male workers reported that those employed in the agricultural sector or those exposed to pesticides showed lower blood levels of reproductive hormones and a high risk of lympho-hematopoietic system cancer in their children. Male workers exposed to complex organic solvents and organic compounds showed a high risk of poor semen quality, increased time to pregnancy, decreased blood levels of reproductive hormones, and a high risk of lympho-hematopoietic system cancer in their children. Male workers employed in occupations that involved significant social contact, or in the leather and livestock industries, and in occupations with high levels of exposure to lead and organic solvents showed a high risk of malignancies, including lympho-hematopoietic system cancer, neuroblastoma, and central nervous system tumors in their children. Studies that investigated both male and female workers reported that children of male smelters showed a high risk of premature birth, and children of male workers exposed to metals showed a high risk of hypospadias and cryptorchidism. Children of male welders and workers employed in the glass, ceramic, and tile industries showed a high risk of premature birth. Conclusion: The findings of this study will serve as basic data for further research on male workers' reproductive health and provide a scientific basis for the development of strategies to protect the reproductive health of males employed in high-risk occupations. Moreover, the results of this study may provide guidelines to improve the understanding of and knowledge on male workers' reproductive health.
Background Although plastic surgeons daily encounter various facial tumors in the field, reports limited on face are scarce. In our study, we want to provide basic epidemiologic data to help clinicians to decide the proper management for their patients. Methods We retrospectively reviewed the medical records of patients including age and gender, location and size of the tumor, histopathologic result, recurrence, type of anesthesia and any associated disorders who had undergone a surgical removal of their facial tumors and received the histopathologic report in the same institution between January 2009 and October 2012. Results One hundred eighty-nine patients with 203 non-melanocytic benign tumors were included. The most frequent site of tumors was the central subunit of the forehead, followed by the lateral subunit of the cheek and the auricular unit. Of 36 different histopathologic results, the epidermal cyst was most frequent, followed by lipoma, pilomatricoma and osteoma. Statistical analysis showed that males were dominant in the epidermal cyst and lipoma groups. While, females were dominant in the osteoma and pilomatricoma groups. No associations were found between lesions and other diseases. Conclusions Our study is the at most specific and concentrated study on non-melanocytic benign tumors of the face. We expect the epidemiologic data of our study may help plastic surgeons who are confronted with so many facial lesions in the field to decide on the most proper management for their patients.
Objectives : The aim of this study was to find correlations between characteristics of Four constitution and Hwa-byung. Methods : Clinical data were collected from Hwa-byung Epidemiologic study data. we selected 130 self-labelled Hwa-byung patients data and 83 of them were diagnosed as Hwa-byung by SCID. We used Hwa-byung SCID, Hwa-byung scale, CES-D, STAI, STAXI and Personality and Physiological Symptom Questionnaire(PPSQ) as evaluation tools. We performed statistical analysis of each 2 groups, self-labelled Hwa-byung group(N=130) and diagnosed Hwa-byung group(N=83). Results : 1. In self-labelled Hwa-byung group, Greater yin score showed significant negative correlation with 3 indices of Hwa-byung scale and significant positive correlation with 1 index. Lesser yin score showed significant positive correlation with 6 indices. In diagnosed Hwa-byung group, Greater yin score showed significant negaitive correlation with 5 indices. In both groups, Lesser yang score showed no significant correlation with any indices of Hwa-byung scale. 2. In self-labelled Hwa-byung group, Greater yin score showed significant negative correlation with both trait anger score and state anger score of STAXI. Lesser yin score showed significant positive correlation with trait anxiety score, state anxiety score and CES-D score self-labelled Hwa-byung group. Lesser yang score showed significant positive correlation with anger-out score of STAXI. But Lesser yin score showed significant negative correlation with same index diagnosed Hwa-byung group. Conclusions : 1. The higher Greater yin score, suppression or denial, psychological defense mechanism, become more stronger. 2. The higher Lesser yin score, anger-out tendency become more weakened and increased prevalence of Hwa-byung symptoms. 3. The higher Lesser yang score, anger-out tendency become more stronger.
Objectives: Diesel engine exhaust (DE) accounts for a significant percentage of air pollutants that are associated with various health outcomes including mortality, asthma, chronic bronchitis, respiratory tract infection, etc. In June, 2012, the International Agency for Research on Cancer (IARC) released the assessment results that classified DE as "carcinogenic to humans" (Group 1). This review is therefore focused on the lung cancer risks of DE. Methods: Literatures were searched using PubMed with key words of "diesel exhaust", "lung cancer", and other related terms for the period between 1990 and 2012. A total of 295 articles were searched and sixteen epidemiologic studies were identified as potentially relevant. Results: Sixteen epidemiologic studies about the lung cancer risks of workers exposed to DE in various occupations were summarized in two tables, 1) retrospective cohort studies and 2) case-control studies. Increased lung cancer risk, although not always smoking adjusted, was observed in 6 out of 8 retrospective cohort studies and 4 of 8 case-control studies. Conclusions: Diesel fuel is widely used in Korea. Exposure to DE is confirmed to be a human carcinogen by IARC. Noncancer health risks of DE also need careful attention as DE is a major source of fine-particle pollution. Along with the efforts for reducing the DE emission through improvements of diesel engines and fuel, and the use of alternative fuels, comprehensive health risk assessment of DE should be conducted to minimize the adverse health effects.
Aim: To report the histologic findings on Whipple resection specimens and thus determine the extent and spread of carcinomas of ampullary region and head of pancreas in our population. Setting: Section of Histopathology, Department of Pathology, Aga Khan University Hospital (AKUH), Karachi, Pakistan. Materials and Methods: A case series of 311 consecutive Whipple resection specimens received between January 1,2003 and December 31, 2014. Specimens processed for histologic sections and representative sections submitted and histologically examined as per established and standard protocols. All relevant tumor parameters including histologic type, histologic grade, pathologic T and N stage and tumor size were assessed. Epidemiologic data were also recorded. All findings were analysed using SPSS 19.0 software. Results: Ampullary (periampullary) carcinomas were much more common than carcinomas of the head of the pancreas, especially in males, with an average age of 53 years. Mean tumor size was 2.5 cms, over 54% were well differentiated. A large majority were pT2 or pT3 and N0. Carcinomas of pancreatic head were also more common in males, mean age was 55 years, mean tumor size was 3.5cms, and over 65% were moderately differentiated. The majority were T2 or T3 and pN1. Prognostically, significant statistical correlation was seen with tumor grade and pathologic T and N stage (p values statistically significant). However, tumor size was not statistically significant. Conclusions: Ampullary carcinomas are more common compared to pancreatic carcinomas. Majority of ampullary carcinomas were well differentiated while majority of pancreatic carcinomas were moderately differentiated. Large majority of both types of cases were pT2 or T3. Histologic tumor grade and pathologic T and N stage are significantly related to prognosis in Pakistani patients with ampullary and pancreatic cancers.
1. Objective This study aimed to find out the epidemiologic characteristics of constitutional disease syndromes at a hospital of Oriental medicine in Seoul. 2. Methods The medical records of 1354 subjects who have received prescriptions and diagnosis of Sasang constitution from January 2008 to December 2009 at a hospital of Oriental medicine were reviewed. General factors and the frequency of the prescriptions according to Sasang constitution were compared and analyzed. 3. Results 1) Among the 1354 subjects, 562(41.5%) persons were males and 792(58.5%) females. 614(45.3%) persons were Soeumin, 369(27.3%) Soyangin, 364(26.9%) Taeumin, and 7(0.5%) Taeyangin. 2) The frequencies of the prescriptions of 14 constitutional disease syndromes were compared. Taeum Syndrome, Esophagus Cold Syndrome and Yin Deficiency Tidal fever Syndrome show the high frequencies among 14 disease syndromes. Chest Heat Syndrome, Deficiency of Yin and Blood syndrome and Soeum Syndrome show the low frequencies among 14 disease syndromes. Interior disease(63.4%) was higher than exterior disease(36.6%) and mild disease(61.8%) was higher than severe disease(38.2%). 3) Among all constitutional prescriptions, Jowyiseungchung-tang was the most common and next rankings were Gupoong-tang and Dokhwaljihwang-tang in turns. 4. Conclusions From all these considerations, it would seem that Taeum Syndrome in Soeumin, Esophagus Cold Syndrome in Taeumin and Yin Deficiency Tidal fever Syndrome in Soyangin show the high frequencies in a hospital of Oriental medicine in Seoul. Large-scale epidemiologic study in Sasang constitutional medicine may be needed on various ways and places.

Background: Mandibular fractures are one of the most common types of facial fractures, the treatment of which can be delayed due to the severity of the trauma resulting in an increase of complications; thus, early evaluation of trauma severity at the time of visit is important. In South Korea, trauma patients are triaged and intensively treated in designated regional trauma centers. This study aimed to analyze the relationship between trauma severity and mandibular fracture patterns. Methods: A medical records review was performed on patients who visited the regional trauma center at our hospital for mandibular fracture between 2009 and 2018. Epidemiologic data and mandibular fracture patterns were analyzed and compared with the conventional facial injury severity scale (FISS). Results: Among 73 patients, 51 were classified as non-severe trauma patients and 22 as severe trauma patients. A higher trauma severity was associated with older age (odds ratio [OR], 1.164; 95% confidence interval [CI], 1.057-1.404) and lower risk was associated with fractures located in the angle (OR, 0.001; 95% CI, 0-0.022), condylar process (OR, 0.001; 95% CI, 0-0.28), and coronoid process (OR, 0.004; 95% CI, 0-0.985). The risk was lower when the injury mechanism was a pedestrian traffic accident (OR, 0.004; 95% CI, 0-0.417) or fall (OR, 0.004; 95% CI, 0-0.663) compared with an in-car traffic accident. Higher FISS (OR, 1.503; 95% CI, 1.155-2.049) was associated with a higher trauma severity. The proposed model was found to predict the trauma severity better than the model using FISS (p< 0.001). Conclusion: Age, location of mandibular fractures, and injury mechanism showed significant relationships with the trauma severity. Epidemiologic data and patterns of mandibular fractures could predict the trauma severity better than FISS.

Background: Despite the fact that testicular cancer is a major health issue with its increasing incidence, very few studies have described its characteristics in the Middle East, particularly in Lebanon. Materials and Methods: We report in this paper a retrospective pilot study of the characteristics of testicular cancer in Lebanon. The demographic, epidemiologic and survival characteristics of 178 patients diagnosed between 1990 and 2015 at an oncology clinic affiliated to Hotel Dieu de France Hospital were analyzed. Results: The mean age at diagnosis was $32{\pm}10years$. The most prevalent testicular tumor was the germ cell type (GCT) (95.2%) of which non-seminomatous tumors (NST) were the commonest (64.7%). Most of our patients were diagnosed at an early stage. Lymph node spread affected most commonly the retroperitoneal region and distant visceral metastases occurred in 14.6%. All patients underwent orchiectomy with 67% receiving adjuvant treatment, mainly chemotherapy. After a median follow up of 2,248 days (75.9 months) 16 patients were reported dead. Two, five and ten-year overall survival rates were 96%, 94% and 89% respectively. The median overall survival rate was not reached. Conclusions: Despite being part of the developing world, demographic, epidemiologic and survival analyses of testicular cancer reported in our study are in line with those reported from developed countries and would allow us to extrapolate management plans from these populations.
