Purpose: A nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst arising anywhere on the face inferior to the nasoalar region. It is thought to arise from either epithelial remnants trapped along the lines of fusion during the development of face or the remnants of the developing nasolacrimal duct. This study examines various features of nasolabial cysts with bony involvement to provide a basis for correct diagnosis and treatment. Methods: Eight cases of nasolabial cyst treated in Soonchunhyang Hospital between March 2002 and July 2010 were examined in terms of their clinical features and radiological and histological findings. Seven patients underwent surgical excision of the cyst via an intraoral, sublabial approach. One underwent incision and drainage. Results: Our eight patients were seven women and one man. The most frequent symptoms and signs were facial deformity and swelling of the nasolabial fold. Computed tomography (CT) showed a well-circumscribed cystic mass lateral to the pyriform aperture. Seven cases had erosive lesions on CT, and the intraoperative findings were consistent with a nasolabial cyst with a bony defect. Typical histopathological findings showed that these cysts were most frequently lined with respiratory epithelium with ciliated columnar cells and cuboid cells. No patient developed complications or recurrences. Conclusion: A nasolabial cyst is often unrecognized or confused with other intranasal masses, including fissural and odontogenic cysts, midface infections, or swelling in the nasolabial area. Therefore, a careful clinical and radiological evaluation should be preformed when considering the differential diagnosis. We present eight patients with nasolabial cysts treated via a gingivobuccal approach with excellent functional and cosmetic results.

Status of benzene exposure was evaluated upon petrochemical workers in the Yeosu Industrial Complex, based on questionnaire responses by workers, review of previous work environment assessment reports between 1996 and 2004, in addition to short-term exposure measurements for unit tasks in the field. Questionnaire results showed that workers in the field were suffering concern on and symptoms of respiratory diseases, cancers or other illnesses of unknown causes. In particular, workers were highly worried about the risk of exposure to chemical hazards including benzene, while conducting specific tasks (e.g. sampling, draining, gauging) among normal operations during which equipments are opened and contents are exposedin the air, as well as periodic turnaround (TA) task. However, the review of previous work environment assessment reports found out that short-term exposure assessment data for unit tasks accounted for less than 1% of total data, and most of them were on 8-hr average exposure level. It also turned out that benzene was not detected in 83% of total samples, suggesting routine but pointless sampling has been repeated. Short-term exposure level was assessed focusing on tasks with high level of complaints on the exposure risk, based on the questionnaire responses. As predicted, a maximum of 741 ppm benzene exposure was reached depending on types and conditions of operations involved. In conclusion, these findings suggest that the evaluation and management on the short-term high exposure tasks including turnaround are crucial in reducing benzene exposure and preventing haematopoietic cancer in workers in the petrochemical industry.

Clinical observations were made on 349 cases of acute drug intoxication who were visited to emergency room of Yeungnam University Hospital during recent 7 years from January 1984 to December 1990. The following results were obtained 1) Total number of cases of acute drug intoxication was 349 which was 0.39% of the total patients of the emergency room during the same period. 2) The ratio of male to female was 1.1 : 1. The age incidence was highest in the third decade(26.7%). The monthly incidence was hightest in May. Higher frequency was observed in summer season. 3) The most common drug of the intoxication was pesticides and herbicides(71.9%), the remainders were miscellaneous drugs(11.2%), sedatives(7.7%), rodenticides(6.3%) and unknown drug(3.2%) in orders. 4) The most common cause of drug intoxication was suicide(69.1%) and the others were accident, unknown cause, intention in orders. 5) Main clinical manifestations were the impairment of consciousness, nausea, vomiting and convulsion. Physical examination revealed increased pulses, increased blood pressure, miosis of the pupil and sweating. Above symptoms and signs were more prominent in pesticide intoxication. Leukocytosis, glycosuria and abnormal LFT were common findings in acute intoxications. 6) The complications were developed in 18.3% among 349 cases and the most common complication was respiratory failure, pneumonia, cardiovascular collapse and pulmonary edema in orders. 7) Overall mortality rate was 8.3% of total cases and mortality rate was highest in herbicide intoxication(22.2%).

Purpose: Chest pain is common in children and adolescents and is a reason for referral to pediatric cardiologists. Although most cases of chest pain in these age groups are benign and do not require treatment, timely diagnosis is important not to miss life-threatening diseases requiring prompt treatment. We investigated certain clinical characteristics that may be useful in the diagnosis of such critical diseases. Methods: Patient medical records between July 2006 and September 2013 were retrospectively examined. We included 517 patients who presented with chest pain to the Department of Pediatrics at Kyung Hee University Hospital in Gangdong. Results: Most cases of chest pain were idiopathic in origin (73.6%), followed by cases with respiratory (9.3%), musculoskeletal (8.8%), cardiac (3.8%), gastrointestinal (2.9%), and psychiatric (1.4%) causes. In 6 patients (1.2%) with air-leak syndrome including pneumothorax or pneumomediastinum, the pain was abrupt, continuous, and lasted for a short period of 1-2 days after onset in the older adolescents. Of the patients with cardiac pain, 13 had cardiac arrhythmias (65.0%), 6 had congenital heart diseases (30%), and 1 had coronary aneurysms caused by Kawasaki disease (5.0%). One patient with atrial flutter had only symptoms of syncope and chest pain. Conclusion: The abrupt, continuous chest pain of a short duration in the older children was characteristic of air-leak syndrome. In patients with pneumomediastinum, radiological diagnosis was difficult without careful examination. Combined syncope should not be neglected and further cardiac workup is essential in such patients.

Purpose: Chloramphenicol and tetracycline are not recommended for treating scrub typhus in pediatric patients because of potential side effects, such as aplastic anemia or tooth discoloration. While clarithromycin has recently been used in adults, few reports have been published on its effects in pediatric patients. We report the clinical profiles of pediatric scrub typhus and the effects of clarithromycin on scrub typhus in children. Methods: We retrospectively analyzed medical records of 56 children with scrub typhus who were admitted between 2004 and 2013 to Chonbuk National University Hospital, Jeonju, Korea. Cases were divided into 3 groups based on the treatment drug (chloramphenicol, azithromycin, and clarithromycin). We compared their clinical manifestations and laboratory findings. Results: All patients exhibited fever and rash. Other common clinical manifestations were eschars (66%), lymphadenopathy (48%), upper respiratory symptoms (42%), abdominal pain (32%), and hepatosplenomegaly (14%). Elevated levels of C-reactive protein, erythrocyte sedimentation rates, aspartate transaminase, and alanine transaminase were detected in 95%, 96%, 84%, and 77% of patients, respectively. Additionally, decreased platelet and white blood cell levels were observed in 43% and 36% of patients, respectively. There were no statistical differences between the treatment groups in mean age (P=0.114) or sex (P=0.507). However, time to defervescence after the treatments differed significantly, being the shortest in the clarithromycin group (P=0.019). All patients recovered without complications related to the disease or drugs. Conclusion: Clarithromycin was as effective as chloramphenicol and azithromycin in pediatric scrub typhus patients and may be used as a first-line treatment drug.

These studies were performed to find out the possibility of automatic detection of the diseased animal with fever by farmers themselves. Firstly, the body temperature of 331 dairy cows was investigated according to major disease symptoms manifested. Secondly, AD 590 thermometer was used to take the teat temperature of the milking cows to determine the possibility of automatic taking of body temperature while milking. The temperatures of scapha of ear and coccygeal artery part were also taken fur the non-milking dairy cows and Korean native cowl 1. The average body temperature of dairy cows associated with respiratory diseases puerperal disease, or mastitis was higher than normal temperature denoting respectively 39.8,39.6, and $39.3{\circ}C.2.$ The teat temperaure of the milking dairy cows with fever($39.5~39.6{\circ}C$) and the cows with mastitis was respectively 1.02 and 0.56${\circ}C$ higher than that of normal cows. 3. The average teat temperature taken by AD 590 was 33.91, 34.93, and 34.50${\circ}C$ in normal milking dairy cows, cows with fever(39.5~39.6${\circ}C$), and cows with mastitis, respectively. 4. The mean temperatures at scapha and coccygeal part of non-milking dairy cows and Korean native cows were 35.62 and 36.63${\circ}C$, respectively. It was concluded that AD 590 thermometer would be usable for the farmers to automatirally detect the body temperature of dairy cows while milking and subsquently to find the diseased cow with fever and that the scapha of ear and coccygeal artery part of the cattle could be the body parts of simply detecting body temperature of non-milking cattle.

This work described 3 infection cases caused by Rhodococcus equi in foals between 3 and 5 months of age. The disease histories were not fully taken from local veterinarians. At least 1 sick foal has been treated with cephalothins followed by penicillins during approximately 1 week, but died without effectiveness and other foals rearing with the animal have been suffering from severe pneumonia which show high fever, laboring respiration, cough and/or nasal discharge. There were many abscessations into lungs of 2 foals in postmortem examination and another 1 sample was pus collected from abscess around the shoulder, indicating the osteomyelitis. Those bacteria were grampositive coryneform and were identified as a R. equi by a polymerase chain reaction (PCR) using primers for R. equi-specific vapA gene. The pathogens were usually resistant to penicillin, ampicillin, amoxycillin/clavulanic acid, cefazolin, clindamycin, sulfamethoxazol/trimethoprim, kanamycin, and tetracycline, while were sensitive to ciprofloxacin, norfloxacin, orfloxacin, gentamicin, erythromycin, neomycin, and vancomycin. Some more foals with respiratory symptoms in 1 horse farm were treated by orally administration with erythromycin during 2 weeks. Because the combination of erythromycin and rifampin has recommended as the treatment for R. equi infections in foals, the local equine veterinarian can choose those antibiotics for the treatment of this disease in future. However, another antimicrobial agent may be necessary if R. equi resistant to both agents is isolated.

PURPOSE: This study aimed to propose an exercise technique that helps improve the skeletal muscle function while suppressing the symptoms of respiratory distress, by mediating squat exercises in whole-body vibration for patients with severe COPD, and comparing the post intervention pulmonary function and activity of quadriceps. METHODS: Totally, 21 patients with severe COPD were randomly assigned to two groups through clinical sampling: experimental group I included 11 patients (Squat exercise combined with whole-body vibration exercise), and experimental group II included 10 patients (Only squat exercise). Before intervention, we measured pulmonary function using a pulmonary function tester, muscle activity of quadriceps using surface EMG, and gait ability using the 6MWT. RESULTS: Comparison of intra-group changes in both experimental groups showed a significant increase in the activity of rectus femoris, vastus medialis, and vastus lateralis, and also in the 6MWT. Intra-group comparisons also revealed significant difference in the activity of rectus femoris, vastus medialis, and vastus lateralis (p < .05). CONCLUSION: Squat exercise combined with whole-body vibration significantly increased the activity of the quadriceps muscle, suggesting that this intervention helps maintain the function of skeletal muscles and prevent muscle atrophy. Therefore, studies to develop protocols using whole body vibration in clinical practice as an exercise method can safely be performed in severe COPD patients, as considered necessary.

From May 1978 to Sep. 1990, 106 patients who had been diagnosed as primary lung cancer and operated on at the Department of Thoracic & Cardiovascular Surgery, Han Yang University, were clinically evaluated. 1. The peak incidence of age was 5th decade of life[37.7%] and 6th decade[29.2%]. Male to female ratio was 3.8: l. 2. Most of symptoms were respiratory, which were cough, chest pain, hemoptysis, and asymptomatic cases were 2.9%. 3. Histopathologic classifications were squamous cell carcinoma[53.7%], adenocarcinoma [23.8%], bronchioloalveolar cell carcinoma[6.6%], undifferentiated large cell carcinoma[6.6%], small cell carcinoma[3.8%], adenosquamous carcinoma[3.8%] and others[1.8%]. 4. Methods of operation were pneumonectomy 49.1%[52cases], lobectomy 21%[22cases] bilobectomy[6cases], lobectomy with wedge resection[3cases], exploration 21.9%[23cases], and resectability was 78.3%. 5. Staging classifications were Stage I [22.6%], Stage II [11.3%], Stage IIIa[42.6%], Stage IIIb[21.7%] and Stage lV[1.6%]. Resectability by Stage; Stage I was 100%, II 100%, IIIa 84.4% and IIIb 30.4%. 6. Causes of most of inoperable cases were invasion of mediastinal structures and diffuse chest wall, and others were contralateral lymph node invasion and malignant pleural effusion. 7. Operative mortality was 6.7% which caused by arrhythmia, sepsis, pulmonary edema, and radiation pneumonitis. 8. On the long term follow up of the resectable cases, overall 1 year survival rate was 58.5 %, 2 year 39%, and 5 year 19.5%. Five year survival rate was 40% in Stage I, 25% in Stage II and 11.7% in Stage Illa. As for the method of operation, the higher 5 year survival rate was observed in lobectomies[33.3%] than in pneumonectomies[10.3%].
