Three cats with 2 weeks to 1 month history of drooling, halitosis, difficulty eating and pain on opening the mouth were presented to local animal hospitals. On physical examination, the gingiva was swollen, bright red and very painful with bilaterally symmetric pattern. Surgically excised abnormal gingival biopsy samples were requested for diagnosis. Histopathologically, gingival epithelium showed severe hyperplasia and ballooning degeneration. Moderate to severe infiltration of lymphocytes and plasma cells were presented in lamina propria. Immunohistochemically, inflammatory cells of the samples demonstrated major positive reactions for T lymphocytes. But some plasma cells also presented. According to polymerase chain reaction, tissues samples were negative for four kinds of feline viral pathogens. Based on the clinical, gross, histopathologic findings, these three cases were diagnosed as lymphoplasmacytic gingivitis in cats. In our best knowledge, this is the first case report in Korea.

A Cocker spaniel (7-year-old, female) was presented with one week of anorexia, halitosis, oral ulcer, intermittent vomiting, acute weight loss and 3-day history of oliguria. The patient was diagnosed with acute on chronic kidney disease and pancreatitis. Hemodialysis was continued three times a week (total 7 sessions) with improved clinical signs and kidney panel, but presented with another episode of abdominal distention, respiratory distress, and large bowel diarrhea. Echocardiography revealed nearly totally occlusive thrombus in the cranial vena cava, as well as a right atrial mass of approximately $2cm{\times}1cm$. The patient was treated with catheter removal, thrombolysis and anticoagulation therapy with recombinant tissue plasminogen activator. During anticoagulation therapy, size of atrial thrombus was not changed and heart function was not improved after treatment. Since clinical signs were deteriorated, the patient was euthanized by owner's request. Catheter-related giant thrombus in right atrium is a rare complication and treatment guideline for atrial thrombus does not exist. This case is first report of hemodialysis catheter-induced thrombus in Korea.

Clusterin is a highly glycosylated protein composed of two disulfide linked subunits. Although its biolobical action is not clearly defined, clusterin seems to be involved not only in remodeling of damaged tissue, but also in production of halitosis, the present study was designated to elucidate the expression of clusterin in the salivary gland of diabetic rats. For this study, 24 Sprague-Dawley rats were used for the experiment and divided into 2groups: control and experimental. The experimental group was composed of 18 rats and the control goup was 6 rats. After nduction of diabetes by STZ injection, the animals were sacrificed at 1,3,5,7,10,14 days. The parotid and submamndibular glands were observed histologically and the transcriptional expression of clusterin in the glands by Northern blot. The finding were as follows : 1. In experimental group, the salivary glands were observed at day 3 and then a seven destructive pattern was found in the glands at day 5. Howere, regeneration of gland tissue occured at day 14. 2. In experimental goup, destructive change was examined in the septal connective tissue after 7 days, and gradually more serious. 3. In experimental group, clusterin was expressed in the submandibular glands after 5 days, but in parotid glands to a lesser extent after 10 days. These results suggest that clusterin seems to be closely associated with histologic changes in the mucous glands rather serous glands.

Objectives The purpose of this study was to survey the status of clinical use of a computerized tongue diagnosis system (CTDS) Methods We searched domestic/international articles using the CTDS from online medical databases including OASIS, NDSL and pubmed. We selected articles on clinical application or reliability of CTDS but excluded articles on mechanical design or software programming for developing a new CTDS. Finally we found 15 articles and classified the articles according to the study purpose. Results Out of the 15 articles, 8 were focused on the clinical application including halitosis, cold/heat syndrome, lung cancer, xerostomia etc. Other 5 articles were aimed at evaluating and improving reliability of CTDS. The other 2 articles were studied for development of differential diagnostic criteria on tongue coating thickness. Conclusion We found out that until now the researches on clinical application of CTDS mainly had been performed for producing a variety of CTDSs. Considering the importance of the tongue color in the traditional Korean medicine, we suggest that at first standard operating procedure for CTDS be developed and researches to develop differential diagnostic criteria on tongue body/coating color be performed and then explore its applications.

Objectives : The aim of the study is to offer basic data that help to reduce dental fear by measuring adult dental fear level with DFS scale. Methods : The subjects were 300 persons including college students in W University and their parents in Jeollabuk-do Province. Data were collected by convenience sampling from May 1 to May 30, 2013. Results : 1. Dental clinic visit provoked pain in 99 people(47.4%). Oral examination and preventive treatment evoked pain in 13 people(6.2%). 2. Women tended to feel much pain than men. Both women and men felt the thrilling fear when a needle pricks the flesh. 3. Respondents having dental caries, gum bleeding, halitosis, shaking tooth, and painful tooth had a higher dental fear level. 4. The direct pain experience(p<0.001) had the greatest influence. The next influencing factor was the insufficient anesthesia(p<0.05). 5. The explanatory power that the pain experience has influence upon dental fear is $R^2$=0.151. Conclusions : The direct pain experience and the insufficient anesthesia experience have the great influence upon patients' dental fear level. Anesthetics and analgesics can be considered as one of the positive methods for pain control.

Although most clinicians now agree that sinusitis can afflict children of all ages, appropriate diagnosis remain controversial. Sinusitis is one of the most challenging diagnoses for a clinician, because there is a lack of validated diagnostic criteria for acute rhinosinusitis. Symptoms generally include nasal congestion, purulent nasal discharge, and cough .The physical examination is often unsuccessful in confirming the diagnosis. If purulent discharge is seen oozing from the middle meatus, the diagnosis of acute rhinosinusitis is almost certain. Purulent drainage may also be seen in the posterior pharynx and accompanied by halitosis. Absence of light by transillumination may indicate acute rhinosinusitis. Imaging studies are not necessary to confirm the diagnosis of sinusitis in children younger than 6 years and should be used sparingly in children older than 6 years. Sinus radiographs still have several advantages over CT scanning including the relatively low cost and the ability to obtain films without the use of sedation in younger children. Positive findings of sinusitis on plain film include air-fluid levels, complete opacification, or mucosal thickening greater then 4 mm. The CT scan however, is significantly more sensitive then plain films in detecting these abnormalities. Although recovery of bacteria from a sinus aspiration is considered reference standard for diagnosis in pediatric rhinosinusitis, its routine used by pediatricians is not practical and therefore is not recommended.

Breath analysis is rapidly evolving as a non-invasive disease recognition and diagnosis method. Metal oxide gas sensors are one of the most ideal platforms for realizing portable, hand-held breath analysis devices in the near future. This paper reviewed the recent developments in metal oxide gas sensors detecting exhaled biomarker gases such as nitric oxides, acetone, ammonia, hydrogen sulfide, and hydrocarbons. Emphasis was placed on strategies to tailor sensing materials/films capable of highly selective and sensitive detection of biomarker gases with negligible cross-response to ethanol, the major interfering breath gas. Specific examples were given to highlight the validity of the strategies, which include optimization of sensing temperature, doping additives, utilizing acid-base interaction, loading catalysts, and controlling gas reforming reaction. In addition, we briefly discussed the design and optimization method of gas sensor arrays for implementing the simultaneous assessment of multiple diseases. Breath analysis using high-performance metal oxide gas sensors/arrays will open new roads for point-of-care diagnosis of diseases such as asthma, diabetes, kidney dysfunction, halitosis, and lung cancer.

Objectives: The purpose of this study was to investigate the relationship between stress and oral health symptoms in adolescents in multicultural families. Methods: The data from the 10th Korea Youth Risk Behavior Web-based Survey (KYRBWS) were analyzed using PASW Statistics 18.0 (SPSS Inc., Chicago, IL, USA). A total of 795 adolescents, whose mother or father's home country is not Korea, were selected as the final analysis subjects. Results: There was a correlation between the subject's stress level and oral health symptoms. Toothache was significantly increased 2.474 times (p<0.001) compared to lower stress levels. Gum pain and halitosis were significantly increased by 2.394 times and 1.820 times, respectively, compared with those who had low stress (0.001, 0.008). Conclusions: The results suggest that stress experienced by adolescents in multicultural families affects oral health symptoms. Therefore, it is necessary to identify the stress factors and levels in adolescents belonging to multicultural families whose physical and emotional changes are evident and develop a customized program considering their characteristics.

A 12-year-old female spayed miniature schnauzer with one month history of halitosis had a cylindrical protruding mass about 2 × 2 × 1 cm in size arising from the right palatine tonsil. Histopathologically, tonsillar mass was covered with stratified squamous epithelium and many lymphoid follicles with germinal center were existed in the upper area of submucosa. Numerous variable sized, occasionally cystic dilated vascular channels (thin walled lymphatic channels) lined by flattened, discontinous endothelial cells were widely distributed throughout the core of fibrovascular stroma. According to immunohistochemistry (IHC), lining endothelial cells in vascular channels showed strong immunoreactivities for CD31 and von Willebrand factor. Based on the gross, histopathologic, and IHC findings, the oral mass of dog was diagnosed as tonsillar lymphangiomatous polyp, the second case in a veterinary field.
