  • Recently the thoracic injuries have been markedly increasing due to the vast increase of traffic accident, industrial disaster, and incidental accident as well as the frequent use of the murderous weapons including gun or rifle. Because the thoracic injuries could involve the heart, lung, and great vessels, and would influence the lives, prompt diagnosis and adequate treatment are essential. Most of thoracic injuries can be managed with the conservative treatment and simple surgical procedure such as closed thoracostomy, but certain cases require open thoracotomy to preserve lives and to return to their normal environment. The authors have analysed the result of 53 cases of open thoracotomy after thoracic injuries mainly according to the patient`s chart review. The mean age was 33.4 years old and male to female ratio was about 5: l. Injury mechanisms that elicited thoracic trauma indicated for open thoracotomy were penetrating[47%] and non-penetrating[53%] injuries. The Most common type of the thoracic lesion was hemothorax with or without pneumothorax and diaphragm rupture was the second. 58\ulcornero of thoracic injuries were accompanied by abdominal injuries and 47% by bone fractures. 34 patients were operated within 24 hours after injury and their average elapsed time was 13.6 hour. The remained patients were operated after 24 hours and their average elapsed time was 7.8 days. 71 cases of operative procedures containing some overlappings were performed: diaphragm repair[28], bleeding control[12], pulmonary and cardiac repair[4 cases] Postoperative complication rate was 32.1% and operative mortality rate was 9.4%[5/53].

  • Backgroud : Now a days, most studies for professional voice user have been performed after artificial voice abuse without consideration of environmental and personal factors, and occupational specificity, therefore those studies have some problems. Objectives : To make a basic guideline for the management of untrained professional voice user, practically we ananalyzed the voice of experimental group. Materials and methods : Just after working, the sustained vowel sounds of the 15 female telephone operators (subjective group) and the 20 normal female persons (control group) were analysed, using a history paper, acoustic analyzer and videostroboscopy. Results : The most common symptom in subjective group was dysphonia. Stroboscopic findings in subjective group were as following ; posterior chink 11 cases (73%), incomplete closure 2 cases (13%), anterior chink 1 case (7%). The mean maximal phonation time in telephone operators was 12.8 seconds and in control group was 16.8 seconds. Jitter, pitch pertubation quotient (PPQ), shimmer and amplitude pertubation quotient (ASQ) were significantly increased in subjective group than control group, but there is no difference between two group in fundamental frequency and noise to harmonic ratio. Conclusion : Untrained professional voice user needs professional career guidance and counseling. And when we manage the untrained professional voice user, we should consider specific occupational, personal and environmental factors as well as laryngeal factors.

  • Malnutrition is a common problem in patients undergoing maintenance hemodialysis(HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in chronic HD patients. We investigated the nutritional parameters of 50 Korean HD patients(mean age: 46.9 $\pm$ 10.3y, men : 23, women : 27) by measuring anthropometric and biochemical blood indices and assessing food intake using 24-h recall method. Also we administered two questionnaires, one for assessing nutritional knowledge about renal disease and dietary therapy, the other for measuring dietary habits related to dietary therapy. According to the distribution of BMI, 21.3% of HD patients were underweight. The hematological values of HD patients, such as plasma hemoglobin, hematocrit, and total lymphocyte count were below the normal range. The serum cholesterol levels were 133.2 $\pm$ 30.5mg/dl. HD patients took energy and protein only 77.5% and 83.1%, respectively, of their RDA. There were significantly positive correlations between nutritional knowledge and intake of nutrients, such as energy, fat, cholesterol, iron, potassium, vitamin B$_1$, vitamin B$_2$, and niacin. Also, there was a significantly positive correlation between nutritional knowledge and dietary habits(r = 0.317, p < 0.05). In conclusion, Korean HD patients showed mild malnutrition and suboptimal nutrition intake. It can be postulated that the dietary intake can be increased by nutrition education improving nutritional knowledge and correcting the dietary habits of HD patients.

  • Malnutrition is a common problem in patients undergoing maintenance hemodialysis (HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in these patients. This study was conducted to evaluate the effectiveness of nutrition education at improving nutritional status of 23 Korean HD patients (mean : 48.6 $\pm$ 10.4 years, men : 8, women : 15). Anthropometric indices, nutrient intakes, and biochemical blood indices were measured before and after a 6-month nutrition education intervention. Anthropometric indices such as percent ideal body weight [PIBW (%)], body fat, body mass index (BMI), mid-arm circumference (MAC), mid-arm muscle circumference (MAMC), and calculated arm muscle area (CAMA) of subjects were within the normal range and not changed by nutrition education. Subjective global assessment (SGA) was significantly increased (p < 0.05) after nutrition education. Intake of total energy, carbohydrate, lipid, Ca, and vitamin B1 was increased significantly (p < 0.05) but intake of phosphorus, potassium, and sodium was decreased (p < 0.05). The serum concentrations of albumin, total protein, and Ca were significantly increased (p < 0.05), but levels of P and K were decreased (p < 0.05) after the intervention. These findings suggest that nutrition education for HD patients can be effective for positively changing nutrient intakes, leading to improvements in blood indices and nutritional status.

  • We have surveyed the epidemiology of functional dyspepsia in 7 cases of Children and investigated the therapeutic effect on Functional Dyspepsia following 4 weeks medication of Naesowhajung-tang using Electrogastrogram. The Results were as followings: 1. Sex ratio are 6 males, 1 female; their mean ages, $9.0{\pm}1.41(7-11years)$; length, $137.2{\pm}13.86cm$; body weight, $35.3{\pm}l1.34kg$. 2. Most of subjects have a normal growth state. But one case have severe growth disturbance. Familial tendency for this disease is noted in 85.8%. 3. Abdominal pain was seen in 100% of subjects. The indicated symptom was lowed in order of abdominal pain(100%), nausea vomiting(71.43%), general fatigue(65.34%), vertigo headache(57.14%), belching(55.38%), etc. 4. The EGG finding after treatment was improved in 53%, aggrevated in 43. In cases, postprandial improvement was more remarkable than fasting improvement. Common cold and antibiotics seems to have functioned as an aggrevating factor on gastric motility. From the above results, Naesowhajung-tang seems to have been used in the treatment of functional dyspepsia for children.

  • This study was undertaken to evaluate the prevalence of significant cervical pathology among women who are high-risk human papillomavirus (HR-HPV)-positive/cytology negative, the most common combination of positive co-tests. The records of 244 women HR-HPV-positive/cytology-negative who had undergone colposcopy at Srinagarind Hospital, Khon Kaen University during January 2010 and April 2014 were reviewed. Mean age was 46.4 years. Of these 224 women, 75 were positive for HPV types 16/18 (33.5%) and 123 were positive for non-16/18 types (54.9%). HR-HPV was not genotyped in the remaining 26 women (11.6%). Prevalence of significant lesions for the entire cohort was 2.4%, and 2.6% and 3.3%, respectively, for those with HPV 16/18 and other oncogenic HPV types. One woman with HPV 16/18 (1.3%) had invasive cervical cancer. Multiparous women were more likely to be infected with HPV 16/18 compared to nulliparous women (36.3% versus 17.6%, respectively). In conclusion, the prevalence of significant cervical lesion among our study population was 2.4%. Multiparous women were more likely to be infected with HPV 16/18 compared to nulliparous women.

  • The study was made to expand the knowledge of the ecology of Cobitis koreensis which is very common in the upper and middle part of rivers in western part of Korea. A number of C. koreensis are found in the creek of Jeonju-cheon located at Segjang-ri, Wanju-gun, Jeonrabug-do Province. The area studied has pebble bottoms. The flow velocity of the river ranges from 20cm to 40cm per second under normal conditions. The sex ratio of male to female was 1:1.34 and the female was 10~25mm larger than the male in total length. Length-frequencies in this population indicate that 20~40 mm fish group is underyearling, 40~60mm is a yearling, and 60~85mm is two-year-old. And the fish longer than 90mm in total length is regarded as being over three-year-old. Based on the ratio of gonadal weight to body weight, spawning in this species began in April and expanded well into June with water temperature 20~26。C, and the individuals became sexually mature over the two-year-old. The number of the eggs was counted from ten matured female fishes. The mean number of eggs in seven 72.6~81.4mm fishes was 908 (595-1, 229) and that of the rest three 86.0~89.0mm was 1, 674 (1, 337-2, 023). The contents of stomach in the other fifteen specimens captured in September 1977 were investigated. While the younger fed almost on the algae, the foods in the adult were largely aquatic insects.

  • Cervical cancer is the fourth most common cancer in women, with approximately 528,000 new cases and 266,000 women dying of it per year in the world. MicroRNAs have recently been in the spotlight as potential biomarkers that regulate gene expression and are involved in tumorigenesis. In the present study, we evaluated miR-1260b as a potential biomarker for screening of cervical cancer by quantitative reverse transcription PCR. We profiled the TCGA data of miR-1260b in 307 cervical cancer tissues. Then, miR-1260b expression levels in 10 cervical cancer tissues and 10 noncancerous tissues were investigated in a pilot study. miR-1260b was found to be significantly up-regulated in cervical cancer FFPE tissues as compared to those in cervical normal FFPE tissues (P = 0.006). The mean expression level of miR-1260b in late-stage (IIB-IVB) was higher than in those with early-stage (IA-IIA). Furthermore, high miR-1260b was found to be associated with high hTERT and Ki-67 mRNA expression, which are representative of tumor prognosis. The results of the pilot study suggest that miR-1260b may be used as a novel biomarker for improving the diagnosis of cervical cancer.

  • Purpose: Pleomorphic adenoma is the most common benign neoplasm in parotid gland. Superficial parotidectomy was usually used to remove the pleomorphic adenoma. But, this method has to remove tumor with normal parotid tissue. Authors did lumpectomy to remove pleomorphic adenoma in parotid gland, because pleomorphic adenoma is wrapped in a capsule as it grows. The purpose of this study is to evaluate the efficacy of lumpectomy as a treatment of pleomorphic adenoma in parotid gland. Method: From 2002 to 2008, 8 patients underwent the lumpectomy of the pleomorphic adenoma in parotid gland. Occurrence of the complications and recurrance were evaluated. Result: Patients were followed-up for a mean 45 months. There were no recurrance or no complication after lumpectomy. Conclusion: Authors suggest that the lumpectomy lead to decrese complications, recurrane and can be used as a procedure for the resection of pleomorphic adenoma in parotid gland.

  • Background: Midface concavity is a relatively common facial feature in East Asian populations. Paranasal augmentation is becoming an increasingly popular procedure for patients with mild concavity and normal occlusion. In this study, we evaluate clinical outcomes following a series of paranasal augmentation. Methods: A retrospective review was performed for patients with Class I occlusion who had undergone bilateral paranasal augmentation using custom-made silicone implants, between October 2005 and September 2013. Patient charts were reviewed for demographic information, concomitant operations, and postoperative complications. Preoperative and postoperative (1-month) photographs were used to evaluate operative outcome. Results: The review identified a total of 93 patients meeting study criteria. Overall, aesthetic outcomes were satisfactory. Five-millimeter thick silicone implant was used in 81 cases, and the mean augmentation was 4.26 mm for this thickness. Among the 93 patients, 2 patients required immediate implant removal due to discomfort. An additional 3 patients experienced implant migration without any extrusion. Nine patients complained of transient paresthesia, which had resolved by 2 weeks. There were no cases of hematoma or infection. All patients reported improvement in their lateral profile and were pleased at follow-up. Complications that arose postoperatively included 9 cases of numbness in the upper lip and 3 cases of implant migration. All cases yielded satisfactory results without persisting complications. Sensations were fully restored postoperatively after 1 to 2 weeks. Conclusion: Paranasal augmentation with custom-made silicone implants is a simple, safe, and inexpensive method that can readily improve the lateral profile of a patient with normal occlusion. When combined with other aesthetic procedures, paranasal augmentation can synergistically improve outcome and lead to greater patient satisfaction.
