  • Squamous cell carcinoma (SCC) is the most common malignant tumor in the oral cavity, and it accounts for about 90% of all oral cancers. Several risk factors for oral SCC have been identified; however, SCC associated with odontogenic keratocysts have rarely been reported. The present study describes the case of a 36-year-old man with SCC of the right ramus of the mandible, which was initially diagnosed as a benign odontogenic cyst. He underwent enucleation at another hospital followed by segmental mandibulectomy and fibular free flap reconstruction at our institution. In this case, we introduce a patient with oral cancer associated with odontogenic cyst on the mandible and report a satisfactory outcome with wide resection and immediate free flap reconstruction.

  • Introduction : Laryngomicrosurgery(LMS) is frequent procedure applying to benign and early malignant larygeal disease such as vocal cord polyp, nodule and early glottic cancer. LMS has been known as safe procedure and short time consuming treatment. So few reports about complications in LMS was done. In this study, complications and problems from LMS were investigated and reported. Method : From 2000, January to 2001, December, 180 patients who were treated with LMS in Asan medical center were studied by retrograde chart review. Results : In these patients, total 9 patients(5%) were suffered from complication. 4 patients (2%) had teeth injury and 4(2%) were suffered from foreign body sensation in tongue and 1(1%) had hypoglossal nerve injury. Main mechanism of complications is thought by pressure injury by laryngoscope blade. No definite correlation between procedure and complication was observed. Conclusion : There are few neural complications with LMS such as lingual and hypoglossal nerve injury. Before operation of LMS, warning and informing of complications by mechanical stress must be done. Gentle procedure and short operation time are necessary to avoid these problems. And patients who have risk factors of oral complications such as dental disease or dental prosthesis must have dental evaluation and treatment before LMS procedure.

  • Delirium is not developed naturally and is not an endogenous disease. However, delirium has occurred in some specific populations, such as the elderly or medically compromised patients. These become limitations on the systematic study of the epidemiology of delirium. Many epidemiologic studies of delirium have been focused on the elderly due to the fact there are relatively few in the general population. In addition, assessment tools with various sensitivity and specificity have been used. Advanced age, male, poorer cognitive and functional status, and alcohol abuse are well known risk factors of delirium. the epidemiological data will be reviewed in the elderly, patients with dementia, hip fractures, patients hospitalized in intensive care units, terminal cancer and patients with stroke.

  • Recently, the prevalence of bladder cancer is increasing in the Korean society. As the risk factors of bladder carcinoma are variable, the early-stage diagnosis is regarded the best preventive practice. Hematuria is a specific sign of the malignancy as well as a kind of various medication-related adverse reactions. Some anti-coagulation therapy can cause bleedings including hematuria to the patients with cardiovascular diseases such as paroxysmal atrial fibrillation (PAF). Therefore, to the clinical pharmacists working in the anti-coagulation services (ACS), a closer monitoring of patients can give an opportunity to find certain ailments unexpectedly. In this case, a patient with PAF had episodes of sporadic hematuria in the course of warfarin therapy even though with its low levels of INR. An ACS pharmacist found a discrepancy between the bleeding symptoms and INR values, and recommended properly the patient to refer urologist. Fortunately, an early-stage of bladder carcinoma was found then followed by an excision performed to the lesion. Therefore, alert-minded and precise monitoring done by ACS pharmacist could optimize the therapeutic outcomes as well as increase the quality of life of the patient.

  • Metabolic syndrome (MS) refers to a clustering of at least three of the following medical conditions: high blood pressure, abdominal obesity, hyperglycemia, low high-density lipoprotein level, and high serum triglycerides. MS is related to a wide range of diseases which includes obesity, diabetes, insulin resistance, cardiovascular disease, dyslipidemia, or non-alcoholic fatty liver disease. There remains an ongoing need for improved treatment strategies for MS. The most important risk factors are dietary pattern, genetics, old age, lack of exercise, disrupted biology, medication usage, and excessive alcohol consumption, but pathophysiology of MS has not been completely identified. Korean Red Ginseng (KRG) refers to steamed/dried ginseng, traditionally associated with beneficial effects such as anti-inflammation, anti-fatigue, anti-obesity, anti-oxidant, and anti-cancer effects. KRG has been often used in traditional medicine to treat multiple metabolic conditions. This paper summarizes the effects of KRG in MS and related diseases such as obesity, cardiovascular disease, insulin resistance, diabetes, dyslipidemia, or non-alcoholic fatty liver disease based on experimental research and clinical studies.

  • BACKGROUND/OBJECTIVES: It is difficult to consistently demonstrate the health effects of soy isoflavones owing to the multitude of factors contributing to their bioavailability. To accurately verify these health effects, dietary isoflavone intake should be measured using a biologically active dose rather than an intake dose. This concept has been expanded to the development of new exposure biomarkers in nutrition research. This review aims to provide an overview of the development of exposure biomarkers and suggest a novel research strategy for identifying the health effects of soy isoflavone intake. MATERIALS/METHODS: We cover recent studies on the health effects of soy isoflavones focusing on isoflavone metabolites as exposure biomarkers. RESULTS: Compared to non-fermented soy foods, fermented soy foods cause an increased concentration of isoflavones in the biofluid immediately following ingestion. The correlation between exposure biomarkers in blood and urine and the food frequency questionnaire was slightly lower than that of corresponding 24-h dietary recalls. Urinary and blood isoflavone levels did not show a consistent association with chronic disease and cancer risk. CONCLUSION: It is crucial to understand the variable bioavailabilities of soy isoflavones, which may affect evaluations of soy isoflavone intake in health and disease. Further studies on the development of valid exposure biomarkers are needed to thoroughly investigate the health effects of isoflavone.

  • In Korea, asbestos removal has been actively carried out nationwide since 2015 when asbestos was completely banned as a first-class carcinogen. Since scattering dust generated in the process of removing asbestos causes fatal diseases such as asbestos lung disease and lung cancer, concerns are growing over the safety of construction workers and building users undergoing dismantling. For this reason, regulations on asbestos sites have been strengthened and prior studies on safety and risk assessment have been conducted, but research on actual site data collection and process planning is insufficient even though safety is reduced due to delay in site construction period. Therefore, it is necessary to analyze the work and delay factors of the asbestos dismantling process and develop an optimized process plan model for workers. This study is an initial step to develop an optimized process plan model that considers the safety and productivity of asbestos dismantling work, and aims to help establish an optimized process plan for asbestos dismantling process using website clone simulation.

  • Interstitial lung abnormalities (ILAs) are radiologic abnormalities found incidentally on chest computed tomography (CT) that can be show a wide range of diseases, from subclinical lung fibrosis to early pulmonary fibrosis including definitive usual interstitial pneumonia. To clear up confusion about ILA, the Fleischner society published a position paper on the definition, clinical symptoms, increased mortality, radiologic progression, and management of ILAs based on several Western cohorts and articles. Recently, studies on long-term outcome, risk factors, and quantification of ILA to address the confusion have been published in Asia. The incidence of ILA was 7% to 10% for Westerners, while the prevalence of ILA was about 4% for Asians. ILA is closely related to various respiratory symptoms or increased rate of treatment-related complication in lung cancer. There is little difference between Westerners and Asians regarding the clinical importance of ILA. Although the role of quantitative CT as a screening tool for ILA requires further validation and standardized imaging protocols, using a threshold of 5% in at least one zone demonstrated 67.6% sensitivity, 93.3% specificity, and 90.5% accuracy, and a 1.8% area threshold showed 100% sensitivity and 99% specificity in South Korea. Based on the position paper released by the Fleischner society, I would like to report how much ILA occurs in the Asian population, what the prognosis is, and review what management strategies should be pursued in the future.

  • Purpose : To evaluate the incidence of arm morbidity following breast cancer surgery including axillary dissection and to identify related factors. Materials and Methods : One hundred and fifty nine patients were studied using a self-report questionnaire and a clinical examination. Lymphedema, reduction of range of motion in shoulder joint and subjective symptoms (pain, impaired arm movement, numbness, stiffness) were evaluated. As related factors, demographic, oncologic characteristics and types of treatment were analysed. Results : The incidence of lymphedema ($\geqq$2 cm difference comparing to unaffected arm) was $6.3\%$, $10.7\%$, $22.5\%$ and $23.3\%$ at each 10 cm, 20 cm, 30 cm, and 40 cm from wrist. Reduction of range of motion in shoulder joint ($\geqq$ 20 degree difference comparing to unaffected arm) was noted In more than 1/3 patients for flexion, abduction and internal rotation. Especially the reduction of range of motion in internal rotation was severe ($>50\%$ reduction) in 1/3 patients. Approximately 50 to $60\%$ of patients complained impaired arm movement, numbness, stiffness and pain. Body mass index (BMI) was the significant risk factor for lymphedema. Conclusion : Lymphedema was present in 1/3 of patients and the common sites of edema were 30 cm 40 cm proximal from the wrist. Also most severe reduction of range of motion in shoulder joint was with internal rotation. There needs weight control for lymphedema because BMI was the significant risk factor for lymphedema. Also rehabilitation program for range of motion especially internal rotation In shoulder joint should be developed.

  • Purpose: Benign anastomotic stricture after an esophagojejunostomy using EEA stapler following a radical total gastrectomy is one of the most serious complications. The purpose of this study is to evaluate the incidence risk factors, and treatment associated with benign stricture. Materials and Methods: From March 1998 to February 2001, 436 patients underwent an esophagojejunostomy with Roux-en-Y anastomosis using an EEA stapler followed by an endoscopy. Thirty three of the 436 patients(5.5%) developed an anastomotic stricture; included 24 of the 33 patients had a benign stricture. Nine patients with a malignant stricture were excluded. Results: The median age of the 436 patients was 57 years $(23{\sim}85\;years)$. Two hundred ninety two patients were male, and 144 patients were female. The median time to diagnosing the stricture was 1.5 months $(0.5{\sim}6months)$. There was no statistical significance in any of the risk factors, including the diameter of the stapling device, the status of adjuvant treatment, the status of reflux esophagitis, and a clinical history of diabetes and hypertension. The strictured patients were treated with balloon dilatation, one to three times, with symptom relief. Conclusion: There were no statistically significant risk factors. However, further study of the vascularity of anastomoses and benign strictures needs to be considered. In the anastomotic strictured patients endoscopic balloon dilatation appeared to be the first line of treatment.
