Background: Chronic stress at work is known to be associated with the risk of developing metabolic syndrome. Recent studies have evaluated stressand its association with metabolic syndrome in specific occupational groups. In the present study, we examined the relationship between stress andthe risk of developing metabolic syndrome in each occupational group. Methods: The present study examined 7,460 Korean workers, aged 20–65 years, whose data were collected from the Korea National Health andNutrition Examination Survey conducted between 2014 and 2016. The information on usual stress awareness was self-reported, and thebiochemical profile of the blood was conducted. The chi-square test and multiple logistic regression analysis were used to investigate therelationship between stress and metabolic syndrome in each occupational group. Results: The metabolic syndrome was prevalent in 26.3% of the study subjects. In the function-related job groups, the individuals with high stress levelsshowed a significantly higher risk of developing metabolic syndrome (odds ratio, 1.625; 95% confidence interval, 1.042–2.534) than those with lowstress levels. An increasing trend was observed, which suggested the increased risk of developing metabolic syndrome across increasing stress levelsin a stratified analysis in many occupational groups, specifically in function-related, viz., manager and expert, office worker, service worker, andsimple laborer (P for trend <0.001) groups. Conclusion The stress levels were significantly correlated with the risk of developing metabolic syndrome in function-related job groups. A differencebetween dose-response association of stress levels and metabolic syndrome existed in each occupational group.

Hypopharyngeal reconstruction is a surgically challenging procedure, and postoperative management is important due to a high rate of complications following surgery. In particular, stricture and fistula formation is the most common long-term postoperative complication. Through systematic review and meta-analysis of 21 studies, a significant radiation effect of stricture and fistula formation was found in patients who underwent hypopharyngeal reconstruction. The perioperative radiation must be seen as a critical factor for stricture and fistula formation in hypopharyngeal reconstruction.

BACKGROUND: Von Recklinghausen disease or neurofibromatosis type 1 is an autosomal dominant genetic disorder of chromosome 17q11.2. The most common characteristic findings of NF 1 include multiple and recurrent cutaneous neurofibromas associated with psychosocial distress. METHODS: Sixteen patients (9 female, 7 male; average age, 31 years; range, 16 to 67 years) with multiple cutaneous neurofibromas between March 2010 and February 2012 were included in the study. All patients were treated with radiosurgical ablation and excision under general anesthesia. RESULTS: All 16 patients were satisfied with the results, when questioned directly during the outpatient department follow-up. The only complaint from a few patients was minimal scarring, but acceptable results were obtained in the end. CONCLUSIONS: The radiofrequency procedure is almost bloodless and quick, creating a smaller necrotizing zone. Therefore, instead of employing the time consuming traditional surgery, such as laser therapy and electrosurgical excision, that produces uncertain results and can affect normal adjacent tissue, treatment of neurofibromas with radiofrequency ablation and excision can be an alternative choice of treatment for patients with a large number of neurofibromas.

PURPOSE: An osteoma is one of the common benign tumors that penetrate the nasal portion, paranasal and frontal sinus. This tumor is mostly found by radiation test accidentally, however in rare cases; it can be found to be touched or with its symptoms as the tumor grows. We report this case since we found and healed the benign tumor which was affecting orbit and the both sides of fronal sinus. METHODS: A 19 year old female patient visited to our hospital due to the mass on her forehead. The symptoms began 3 years ago but no special symptom was found except for touchable mass. She was diagnosed as the osteoma of superior orbital parts and both sides of frontal sinus using X-ray and CT scanning. The size of osteoma was 5x2.5x3.5cm and indicated the patterns penetrated to the right side of orbital region. The osteoma excision was conducted with coronal incision and wide area of defect part in frontal sinus and superior orbital part were reconstructed by cranial bone graft and resorbable fixation plates. RESULTS: The patient recovered without any postoperative infections or complications and symptoms. Dysaesthesia was found on her frontal area but improved in 1 month after the surgery. CONCLUSION: The occurrences of osteoma in frontal sinus are rare and can be treated with conservative methods if there are no infections and symptoms. We report this case since we found the benign tumor, which was affecting orbit and the both sides of fronal sinus and healed it with coronal resectomy without any complications.

PURPOSE: Liposarcoma is the most common soft tissue sarcoma, and usually occurs on the thigh or in the retroperitoneal space, but rarely in the oral region. This report presents a case of liposarcoma of the cheek and includes a review of the literatures. METHODS: A 21-year-old woman was admitted with a palpable mass in her cheek of about two years duration, which increased in size gradually initially, but had increased rapidly over the three months. There was no particular pain or tenderness. MRI showed a well-enhanced, well-defined mass, which suspected to be hemangioma. RESULTS: The spherical, well-encapsulated mass was surgically excised. Biopsy results revealed myxoid liposarcoma. FDG PET-CT on the seventh postoperative day, revealed a minimal to mild FDG-uptake soft tissue lesion around the mass defect area without evidence of distant metastasis. The patient is being observed and undergoing radiation therapy. CONCLUSION: Liposarcoma in the head and neck region is a rare disease, and can be overlooked as a benign tumor without a pathologic diagnosis. Therefore, proper treatment and follow-up are required based on an understanding of this disease.

PURPOSE: Epithelial-myoepithelial carcinoma (EMC) represents about the 1% of the malignant neoplasms in the salivary glands and clinically most commonly found localized, well defined and sometimes presents orofacial pain. Treatment of choice is surgical excision. Postoperative radiotherapy can be used when surgical margins are doubtful. We report our experience of EMC of the parotid gland. METHODS: A 78-year-old man presented with a three-year history of a localized, painless, 7 x 6 cm sized recurred tumor in his right preauricular area. He was diagnosed as EMC of the right parotid gland. So a total parotidectomy was performed. In his old medical history, he had a mass in the same area 5 years ago. The diagnosis of pleomorphic adenoma was made and the mass excision was performed at the local clinic without further evaluation. RESULTS: It was unable to visually discriminate between the tumor and the normal tissue. So a total parotidectomy was performed. The patient was got post-operative radiotherapy and was followed up for 9 months. There was no specific evidence of recurrence. CONCLUSION: We present a case of EMC of the parotid gland in right preauricular area, which is uncommon. So we report a uncommon case of EMC to discuss about our experience with relevant journal discussion.
