Mucoepidermoid carcinoma occurs commonly in salivary gland, but rarely in lacrimal gland. In literature about ten or more cases of mucoepidermoid carcinoma of the lacrimal gland have been described. A 73-year-old woman had noted upper lid swelling and lacrimation of the left eye for 2 months. Computed tomographic scan demonstrated a large homogenous mass on superotemporal portion of the left orbit. The mass extended into the left temporal fossa, middle cranial fossa, and ethmoidal sinus with bone destruction. Histopathologically, the mass was proved to be a intermediate grade mucoepidermoid carcinoma of the lacrimal gland.

The purpose of this study was to improve the dietary attitudes of elementary students through nutrition labeling education. A class of fifth-grade elementary students was selected and educated for basic nutrition and reading of nutrition labeling for 8 weeks by using education materials from the KFDA. After the education, the children were subjected for the practice of reading nutrition labeling during winter vacation, and the changes in their dietary attitudes and practice were measured by using questionnaires for children and their parents along with measuring physical changes. The results were as follows: The level of nutritional knowledge was improved significantly after the education (p < 0.05). Nutrition labeling education increased the children's frequency of reading nutrition labeling from 34.2% to 57.9% while purchasing processed foods (p < 0.05), and 92.1% of the children answered that their dietary attitudes improved by nutrition labeling education. However, no improvement in physical measurements was observed after education. This result suggested that 8-week of education were not enough to show the improvement in physical measurements, and long-term and repeated education is necessary. After the education, most children answered that they recognized the benefit of reading nutrition labeling and they would read the nutrition labeling when purchasing processed foods. Parents also recognized the necessity of nutrition labeling education in school and suggested the need of nutrition labeling be easy to read. The above results suggested that nutrition labeling education is an effective way for improving dietary attitudes of children.

BACKGROUND: Mycobacterial false-positive cultures have rarely been recognized in Korea, even though the rate of false-positive cultures of Mycobaterium tuberculosis has ranged from 0.4% to 4.0%. We estimated the false-positive rates by the review of medical records from whom mycobacterial cultures were requested, retrospeaively, after a bout of false-positive cultures was discovered in specimens treated in a single day. METHODS: Of the total 2,245 specimens, including 337 positive cultures of mycobacteria, during the period of January and June 1999, seventy-two specimens that showed colonies less than or equal to 5 colonies were reviewed, and classified as tuberculosis-likely group, tuberculosis-unlikely group and unclassifiable group by the clinical and radiological evidences, anti-tuberculosis therapy, and microbiological results. RESULTS: Tuberculosis-unlikely group was 21 specimens from 20 patients, and unclassifiable group was five specimens from four patients. So, the false-positive rates were estimated as 0.9- 1.1% of total cultures and 6.2-7.7% of positive cultures, according to excluding or including the unclassifiable group. CONCLUSION: Care should be taken for lowering false-positive mycobacterial cultures. Especially when a culture turned out to be positive with low colony isolates, more careful interpretations should be preceded before reporting the results by the review of medical records and communication with physician in charge.

An African swine fever (ASF) outbreak in wild boars was first reported on October 2, 2019, in South Korea. Since then, additional cases were reported in South Korea's border areas. We here report the identification of ASF virus (ASFV) DNAs from two out of eight environmental abiotic matter samples collected from areas where ASF-positive wild boar carcasses were found. Comparative genomic investigations suggested that the contaminating ASFV DNAs originated from the wild boar whose carcass had been found near the positive sample sites.This is the first report on the identification of ASF viral material in wild boar habitats.

BACKGROUND: Endoscopic mucosal resection (EMR) is now in clinical use for the management of mucosal and submucosal tumors of the stomach (including early gastric cancer), but its use is limited by the size, depth, and the location of the tumor. METHODS: After the introduction of a new concept of laparoscopic intra-gastric surgery (L.I.G.S.) in which all trocars and surgical instruments are inserted directly into the gastric cavity to perform the resection of mucosal or submucosal lesions of the stomach by Dr. Ohashi, sixteen patients with a mucosal or a submucosal tumor in the posterior wall of the stomach have been successfully treated by L.I.G.S. in our hospital since 1995. RESULTS: 2 patients with early gastric cancer, 9 with a leiomyoma, and 5 with polyps. Twelve (87.5%) of the tumors were located in the antrum and 4 (12.5%) in the body. L.I.G.S. was successfully done on 14 patients (93%) with conversion to a minilaparotomy in 1 patient. The leiomyoma located in the lesser curvature was treated by L.I.G.S. through an anterior gastrotomy using hand suturing. The operationg time was about 100-160 minutes for the L.I.G.S., 120 minutes in the conversion case, and 180 minutes in the L.I.G.S. through an anterior gastrotomy. Postoperative pain was negligible in all cases, and the patients were discharged uneventfully six to seven days after surgery. The follow-up period was 1 to 37 months, and there were no recurrences. The important points of this approach are confirmation of the location of the tumor by both gastrofiberscopy and laparoscopy, excluding the determination of regional lymph node metastasis by endoscopic ultrasonography, and proper selection of the trocar sites. CONCLUSION: We conclude that L.I.G.S. is technically feasible, safe, and useful for a mucosal or a submucosal tumor in the posterior wall of the stomach and that it should be considered as a viable alternative to endoscopic mucosal resection and conventional gastric resection.

BACKGROUND/AIMS: Laterally spreading tumors (LST) were growthed along the colonic wall. These tumors were high malignant potential compared to colon polyp. We analyzed clinicopathological characteristics of these tumors. METHODS: From June 1996 to June 2001, twenty nine patients were diagnosed by colonoscopy. These lesions were classificated macroscopic (granular type and nongranular type) and microscopic findings. RESULTS: 20 male and 9 female were enrolled (mean age, 68.1). Among the LST, 41.4% were 20~30 mm in diameter, and 7% were larger than 30 mm. According to macroscopic findings granular types were 72.4% (21/29) and nongranular types were 27.6% (8/29). In macroscopic findings, tubular types were 48.4% (14/29), malignant changes were 31.3% (9/29). Tumor size was only significant factor in malignant potential of LST (p=0.004). Endoscopic mucosal resection was performed in 72.4% (21/29), operation in 8 (27.6%). Rate of submucosal invasion in LST was 3.4% (1/29, sm1). Recurrent rate of endoscopic treatment group was 9.5% (2/21). CONCLUSIONS: Most of LST were good indication for endoscopic treatment, but larger tumor size and irregular surface of tumor were suspected to be submucosal invasion. Therefore these lesions were performed other procedures as endoscopic ultrasound or computerized tomography for invasion depth.

BACKGROUND: Recently the incidence of coronary artery disease has been increased rapidly in Korea. After the introduction of coronary care unit, the mortality rate of cardiovascular patients has been decreased. The predictive factors for mortality in patients admitted at Coronary Care Unit (CCU) are important in the management of acutely ill cardiovascular patients. METHODS: One thousand one hundred and thirty patients (64.8+/-14.5 years), who were admitted at CCU from January 2002 to June 2003, were analyzed. The patients were divided into two groups according to mortality: the survived group (Group I: n=1055, 63.3+/-13.3 years) and the moribund group (Group II: n=75, 64.8+/-14.1 years). Clinical characteristics, risk factors, clinical diagnosis, laboratory, echocardiographic and coronary angiographic findings were compared between the two groups. RESULTS: The overall mortality at CCU was 6.6%, 75 out of 1130 patients. Age and sex were not different between both groups. Coronary artery disease was the most common cause of admission (886 out of 1130 patients) and death (46 out of 75 patients). Coronary angiographic findings were not different between the two groups. Left ventricular ejection fraction (LVEF) by echocardiogram was higher in Group I than in Group II (53.1+/-15.6% vs. 42.3+/-16.3%, p<0.05). Predictive factors for mortality by multiple logistic regression analysis were low LVEF (OR 11.4, 2.9-21.4 95%CI, p<0.001), no performance of percutaneous coronary intervention (PCI, OR 10.8, 2.5-17.8 95%CI, p<0.001) and clinical diagnosis of aortic dissection (OR 3.8, 1.3-9.8 95%CI, p=0.021). CONCLUSIONS: The predictive factors for mortality at CCU were low LVEF, no PCI and aortic dissection.

BACKGROUND: Recently, The number of patients who have been complaining of the vertigo or dizziness has been increasing due to rapid growth of elderly population and senile disease. The differentiation of dizzy patients is not familiar to most emergency physicians. This study was designed to differentiate true vertigo and to investigate the clinical difference among central vertigo, peripheral vertigo, and other causes of dizziness. METHODS: The authors analyzed the cases of 237 dizzy patients who visited the emergency department of Chonnam University Hospital during the recent 2 years. For the base of dizziness, associated past illnesses, severity, nystagmus type, and the causes of central and peripheral vertigo. RESULTS: Female patients were 142(59.9%) and male patients were 95(40.1%). The most common age group was the 6th decade. The origin of dizziness was classified as peripheral cause(25.3%), central cause(32.9%), and others(41.8%). As to nature of the dizziness, the rotatory sense was dominant in peripheral vertigo and the floating sense and blurred vision in central vertigo. Peripheral vertigo was triggered by position change of head and body, and central vertigo by the eye movement. Audiograms I showed that most patients with central vertigo had normal hearing, but 46.7% of thoswith peripheral vertigo had an abnormal hearing disturbance. Nystagmus was more prevalent in peripheral vertigo CONCLUSION: History taking and physical examination played an important role in the diagnosis of dizzy patients. An important part of the diagnosis of a dizzy patient could be to evaluate the peripheral origin, the central origin and others causes. Because central vertigo may be associated with a significant neurological pathology, special radiological studies, including MRI and CT, are mandatory to rule out a devastating brain lesion.

BACKGROUND AND OBJECTIVES: The impact for recannulation of an artery, where a vascular closure device had been used following percutaneous coronary intervention (PCI), has not been evaluated. The aim of this study was to determine the feasibility and safety of recannulation of the femoral artery following the use of an Angioseal(r) following PCI. SUBJECTS AND METHODS: Between February 2002 and June 2004, 110 patients (Group I: 60.0+/-9.0 years, 84 male), who underwent a 6-month follow-up coronary angiography (CAG) following PCI and the use of an Angioseal(r) closure device, were compared with a further 110 randomly assigned patients (Group II: 61.4+/-9.2 years, 78 male), who received manual compression for femoral artery hemostasis following PCI during the same period. The occurrence of femoral puncture site complications, the time to active ambulation following PCI and procedural difficulties for recannulation during the follow-up CAG were analyzed. RESULTS: The baseline clinical characteristics and procedure related factors were similar between the two groups. No major complications were noted in either group. There were no differences in the incidence of minor complications, including puncture site oozing or hematoma, between the two groups. The time to active ambulation was significantly shorter in group I than II (7.2+/-2.7 vs. 17.3+/-4.2 hours, p=0.001). At the 6-month follow-up CAG, no major complications associated with re-puncture at the same site of the femoral artery were noted, and there were no differences in the incidence of minor complications between the two groups. CONCLUSION: An Angioseal(r) was a convenient method of hemostasis, which promoted early ambulation without difficulties in the reuse of the femoral artery.
