The pleomorphic adenoma is the most common neoplasm involving both the major and minor salivary glands. It is a benign, slowgrowing tumor, but local recurrences can occur. The pleomorphic adenoma gene 1 (PLAG1), which is a novel zinc finger gene, is frequently activated by reciprocal chromosomal translocations involving 8q12 in a subset of salivary gland pleomorphic adenomas. This experimental study was preformed to observe the translocation patterns between PLAG1 gene and the three translocation partner genes. We also have analyzed the presence of PLAG1 transcripts by RT-PCR. CTNNB1/PLAG1 gene fusion was observed in three of nine pleomorphic adnomas. However, LIFR/PLAG1 and SII/PLAG1 gene fusions were not detectable. All of three gene fusions was not detectable in one Warthin's tumor and three inflammatory salivary gland tissues. PLAG1 transcripts were expressed in all inflammatory salivary gland tissues and tumors except for three pleomorphic adenomas. Of particular one pleomorphic adenoma showing CTNNB1/P AG1 gene fusion did not express PLAG1 transcipt. Our data indicate that gene fusion involving PLAG1 is a frequent event in pleomorphic adenoma, but correlation between gene fusion involving PLAG1 and PLAG1 transcription is not definite.

PURPOSE: The purpose of this study was to explore perception of clinical experience between the initial and final practice and to explore changes in the perception of clinical experience. METHODS: The study used a Q-method to measure perception of clinical practice. Thirty-six statements made up the finalized Q-sample. The P sample used thirty three nursing college students from K university. The initial collection was done in the first semester of their junior year and second collection was done in the last semester of their senior year. The Q-sorts by each student were coded and analysed with the Quanl PC program. RESULTS: Many students classified as having the perception type 'alienation of ideal and reality' or 'perception of limitation of ability' in the initial clinical practice changed to the type, 'active participation' by the final clinical practice. Further, in the initial clinical practice, part of 'active participation' and 'perception of limitation of ability' changed to 'alienation of ideal and reality'. CONCLUSION: This study shows that perception of their clinical practice by student nurses changed in a positive direction through clinical experience and that this fact was related to the level of satisfaction with nursing. The knowledge and understanding obtained in this research provide insights for nursing faculty and students involved in nursing education.

Sjogren syndrome is a chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands resulting in dry mouth and eyes. Approximately one-third of patients present with systemic manifestations, but respiratory muscle involvements have been rarely reported. We report a case of acute respiratory failure complicated by primary Sjogren syndrome. Muscle biopsy revealed perivascular lymphocytic infiltrations. Corticosteroid therapy improved respiratory muscle weakness. Sjogren syndrome should be considered as one of the underlying diseases causing acute respiratory failure.

BACKGROUND AND OBJECTIVES: The incidence of deep neck infection has decreased after the introduction of antibiotics and improvement of oral hygiene, but they still may be lethal especially when life-threatening complications occur. The purposes of this study are to find out common organisms, rates of antimicrobial resistance in the deep neck infection. SUBJECTS AND METHOD: We have conducted a retrospective study of 76 patients with the diagnosis of deep neck infection that had been seen between January 1998 and December 2003. RESULTS: The most common pathogens found were Streptococcus viridans (34%), followed by Klebsiella pneumoniae (19.4%), Streptococcus Group F (11.9%), beta-hemolytic streptococci (11.9%) and Peptostreptococcus (7.5%). Staphylococcus species was not found. Of the aerobes found, 74.1% were sensitive to all antibiotics. All Streptococci, with one exception, were not resistant to any antibiotics. All Klebsiella pneumoniae were resistant to ampicillin. Klebsiella pneumoniae were cultured in 50% of DM patients. CONCLUSION: The most common pathogens were Streptococcus viridans (34%). Of these aerobes, 74.1% were sensitive to all antibiotics. All isolated microorganisms were sensitive to ampicillin/sulbactam (Unasyn(R)) used before the results of bacterial cultures.

BACKGROUND AND OBJECTIVES: Supraglottic laryngectomy is a well established technique for the treatment of appropriate carcinoma of supraglottic larynx. The purpose of this study was to determine factors that may contribute to postoperative aspiration related to deglutition problem following supraglottic laryngectomy. MATERIALS AND METHOD: A retrospective analysis of medical records of 19 patients who consecutively underwent supraglottic laryngectomy was undertaken. Contribution of the following factors was investigated: age, T stage, pack-years of smoking, and parameters of pulmonary function test. The authors used a computerized acoustic analysis program (CSL-MDVP) to measure fundamental frequency, jitter, shimmer, and noise to harmonics ratio. RESULTS: Eleven patients had no problem, 5 patients had clinically insignificant problem, and 3 patients had moderate problem in postoperative 6 months. A greater number of pack-years of smoking and decreasing FEV1/FVC were significantly correlated with poor outcome with regards to postoperative aspiration and deglutition problem. No statistically significant difference was seen between patients with supraglottic laryngectomy and the control group. CONCLUSION: This study showed that less than 60% FEV1/FVC signifies a greater risk for postoperative aspiration.

This study evaluated the efficacy and safety of medical shampoo containing terbinafine hydrochloride and chlorhexidine gluconate in dogs with dermatophytos is complicated with bacterial infection. Although several studies in dogs and cats with fungal dermatitis have found that oral administration of terbinafine is effective for controlling clinical signs, the topical form of terbinafine has rarely been studied in dogs and cats. Therefore, this study evaluated the efficacy of medical shampoo containing terbinafine hydrochloride and chlorhexidine gluconate in dogs with dermatophytos is complicated with bacterial infection. Eight dogs infected with Microsporum spp. complicated with bacterial infection were enrolled in this study. These dogs were further blindly divided into Group 1 (no treatment, fourdogs) and group 2 (treated with medical shampoo with terbinafine/chlorhexidine, four dogs). Clinical improvement was evaluated using bacterial and fungal cultural evaluation combined with clinical evaluation. This study found that the medical shampoo has sufficient efficacy to treat varying degrees of dermatophytosis complicated with bacterial infection in dogs, although the speed of improvement differed according to the degree and type of infection. Our study also found that combined therapy using antifungal and antibacterial agents can improve clinical signs more effectively and rapidly, suggesting that concurrent bacterial infection plays a significant role in the development of dermatitis.

PURPOSE: We performed a pulmonary function test with simple, computerized spirometry composed of pneumotachometry and evaluated the predicted normal values of air flow rates and lung volumes in healthy Korean children. We calculated each of the simple and complex linear and logarithmic regression equations setting the predicted values. METHODS: Four hundred and fifty-two healthy children were enrolled from December, 1994 to August, 1995. We measured air flow rates (FVC, FEV1, PEFR, FEF25-75) and lung volumes (VC, ERV, IC, VE). Data was analyzed according to sex, age, height, weight, and body surface area. RESULTS: In 452 children (male : 282, female : 170), the age distribution was from 8 through 19 years, the height from 121cm to 180cm and the weight from 21kg to 79kg. We could get determinant coefficients between parameter and air flow rates. In boys, height showed the highest determinant coefficient in examing air flow rates, followed by age, body surface area and weight in order. In girls, body surface area showed the highest determinant coefficient in examing air flow rates, followed by height, weight, and age in order. A determination coefficient to the parameter was the highest with FVC. We could get determinant coefficients between parameter and lung volumes. Boys showed high determinant coefficient with only IC, girls with VC and IC. In examing IC, height showed the highest determinant coefficient, followed by body surface area and weight in order. Predicted values of pulmonary function test were generally higher in boys than in girls. CONCLUSION: After performing the pulmonary function test in healthy Korean children, we report their normal values of air flow rates, lung volumes and regression equations for the predicted values.

Sudden bilateral hearing loss is mainly caused by peripheral otologic disorders or psychogenic origins. Bilateral temporal lobe infarcts can be one of the rare causes. We report a 50-year-old man presented with cortical deafness due to bilateral temporal lobe infarctions. He was admitted at hospital because he did not respond to any verbal questions or environmental sounds, although he understood written commands partially and spoke fluently. Brain MRI demonstrated ischemic infarcts in both temporal lobes involving primary auditory cortex.

Extrahepatic portal vein obstruction (EHPVO) is the most common cause of pediatric portal hypertension and can cause life-threatening variceal bleeding. MesoRex shunt (MRS) is a surgical procedure that restores physiological portal venous blood flow to the liver by using a graft to connect the superior mesenteric vein and the left portal vein within the Rex recess, and can relieve variceal bleeding and other complications associated with EHPVO. Although the MRS is regarded as an optimal and potentially curative treatment with good long-term patency, graft thrombosis or failure due to unknown causes is not rare, prompting the need for further research on the risk factors of graft failure or poor patency. Herein, we report two cases of EHPVO in patients with recurrent or uncontrolled variceal bleeding, one treated with the classic Rex shunt and the other with the modified Rex shunt, which resulted in a failure and success, respectively.
