OBJECTIVES: The objective of this study is to measure and to compare the rate of depression, anxiety, self-esteem and the quality of life of the patients with chest pain. Based on the result of this study, the necessity of the psychiatric assessment and treatment of the patients with chest pain is emphasized. This study is a preliminary research for a larger scale investigation to be carried out in the future. METHODS: Thirty nine patients with chest pain who visited Cardiovascular Division of Dept. of Internal Medicine Pusan National University Hospital and fourty normal control group(NC) were included in this study. The patients were classified into typical chest pain group(TCP, N=19) and atypical chest pain group(ACP, N=20) based on the cause of the pain. The cause was determined by cardiac computed tomography, exercise stress test, coronary angiography, and questionaires by a cardiology specialist. The patients were assessed with Beck Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI), Rosenberg Self-Esteem Scale(RSES) and Korean version of the Smith Klein Beecham 'Quality of Life' scale(KvSBQOL). RESULTS: 1) When the risk factors of cardiac disease is compared, most of the factors(Hypertension, Diabetes, Hyperlipidemia, Cerebral infarction) did not differ significantly among the two chest pain groups, except for the family history, for which TCP group showed higher risk than ACP group did. 2) As for the self-report questionaires scores, BDI score, which indicates the rate of depression, of both ACP group and TCP group was significantly higher than that of NC group in BDI for depression. STAI score, which measures anxiety, was also significantly high in both groups. Especially, STAI score was significantly higher in ACP group than TCP group. 3) In the aspect of self-esteem and quality of life, ACP group scored significantly lower than TCP group and NC group. The scores for TCP group and NC group did not differ significantly. CONCLUSIONS: The patients with chest pain showed more depression and anxiety than normal control group, regardless of the cause of the pain. However, TCP group did not show significantly larger drop in self-esteem and quality of life than ACP group did. This result implies that early psychiatric assessment and treatment is needed for the patients with such chest pain, since it is highly likely that the pain would lead to lower quality of life of the patients.

The use of flowable composite resins as liners in class II packable composite restoration has been suggested by some manufacturers. However, the contributions of this technique are unproven. The purpose of this study was to compare the gingival microleakage in class II packable composite restorations with or without the use of flowable composite resins as liners. Slot cavities were prepared on both proximals of 80 extracted human molars and randomly assigned to 8 groups of 20 each. The gingival margins were located at 1mm above CEJ in 80 cavities (group1-4) and 1mm below CEJ in 80 cavities (group5-8). The prepared teeth were mounted in the customized tray with adjacent teeth to simulate clinical conditions and metallic matrix band (Sectional matrix) and wooden wedges were applied. After acid etching and application of Single Bond, each group was restored with the following materials using incremental placement technique: Group 1,5 (Filtek P60), group 2, 3, 4 and group 6, 7, 8 (AeliteFlo, TetricFlow, Revolution/Filtek P60). All specimens were thermocycled 500 times between 5degrees C and 55degrees C with 1 mimute dwell time, immersed 2% methylene blue dye for 24 hours and then rinsed with tab water. The specimens were embedded in clear resin and sectioned longitudinally through the center of restoration with a low speed diamond saw. Dye penetration at gingival margin was viewed at 20 magnification and analyzed on a scale of 0 to 4. Kruscal-Wallis One way analysis and Mann-Whitney Rank sum test were used to analyze the results. The results of this study were as follows. 1. The leakage values seen at the enamel margin were significantly lower than those seen at the dentin margin(P<0.05). 2. On the enamel margin, packable composite resins with flowable liners showed lower leakage than those without flowable liners, but there were no significant differences among the four groups(P>0.05). 3. On the dentin margin, four groups demonstrated moderate to severe leakage, and there were no significant differences in leakage values(P>0.05).

The objective of this study is to evaluate the effect of an additional application of bonding resin on the bond strength of resin luting cements in both the light-cure (LC) and self-cure (SC) modes by means of the microTBS tests. Three combinations of One-Step Plus with Choice, Single Bond with Rely X ARC, and One-Up Bond F with Bistite II were used. D/E resin and Pre-Bond resin were used for the additional application. Twelve experimental groups were made. Three mandibular 3rd molars were used in each group. Indirect composite blocks were cemented on the tooth surface. 1 x 1 mm2 dentin-composite beam for microTBS testing were made and tested. When total-etching dentin adhesives were used, an additional application of the bonding resin increased the bond strength (P < 0.05). However, this additional application didn't influence the bond strength of self-etching dentin adhesives (P > 0.05). In conclusion, the results suggest that an additional application of the bonding resin increases bond strength and enhances quality of bonding when using total-etching dentin adhesives.

Diagnosis and analysis of occlusal relationships are important factors in prosthetic treatment. A thorough occlusion analysis and evaluation should be performed before treatment to restore a stable interocclusal relationship. Analysis and evaluation are essential during the treatment process and at regular follow-ups. Recently, with the development of dental equipment and digital processing methods, new quantitative analysis methods that can record the patient’s occlusal relationship have been introduced. Among them, the T-Scan Novus (Tekscan Inc., S. Boston, MA, USA) displays the strength of the initial contact point and the occlusal contact point of the teeth using a pressure sensor. With this, occlusal contact time of the teeth, anteroposterior and left-right balance of occlusal force can be compared. The Dental prescale II (GC Co., Tokyo, Japan) scans the occlusal contact point using a pressure-sensing film and analyzes the density of the contact point.It can measure the distribution and strength of the occlusal force of the teeth in the most natural occlusion state. Based on this, appropriate prosthetic treatment (four-unit fixed partial denture, removable partial denture, complete denture, and complete oral restoration cases) was performed according to the area and extent of the patient’s tooth loss. The patient’s occlusion at the first visit, treatment stage, right after treatment, and regular follow-up were compared and evaluated using a quantitative method for appropriate occlusion analysis using T-Scan Novus and Dental prescale II. This report enhances the understanding of occlusion analysis during prosthetic restoration. The results satisfied both the clinician and patients in terms of function and aesthetics.

BACKGROUND/AIMS: The tumor-node-metastasis (TNM) staging is an useful system to assess the prognosis of any solid cancer. As new TNM staging classification of 7th stomach cancer was revised in 2009, we evaluated the prognostic predictability of the 7th International Union Against Cancer/American Joint Committee on Cancer (UICC/AJCC) TNM classification compared to 6th UICC/AJCC TNM classification in gastric cancer. METHODS: From January 2000 to December 2009, 5-year survival rates of 266 patients with gastric cancer were calculated by the 6th and 7th UICC/AJCC TNM classification. RESULTS: Using the 7th UICC/AJCC TNM classification, there was no significant difference in the 5-year cumulative survival rates (5 YSR) between stage IIA and IIB, IIB and IIIA, and IIIA and IIIB (70% vs. 71%, p=0.530; 71% vs. 80%, p=0.703; 80% vs. 75%, p=0.576, respectively) though significant differences of the survival rates were observed among stages of 6th edition. Using T stage of 7th edition, 5 YSR was not different between T2 and T3 (86% vs. 82%, p=0.655). Using N stage of 7th edition, 5 YSR were not different between N1 and N2, N3a and N3b (79% vs. 81%, p=0.506; 41% vs. 17%, p=0.895, respectively). CONCLUSIONS: The 7th UICC/AJCC TNM classification had poor prognostic predictability in gastric cancer compared to the 6th edition.

A healthy 34-year-old man was admitted to the intensive care unit through the emergency room with a drowsy mentality and severe chilling. Following a diagnosis of septic shock of unknown origin, the patient was treated with broad spectrum antibiotics and massive hydration. After recovery of consciousness, he complained of a severe toothache that originated from the right lower teeth. Under dental consultation, he was diagnosed as having an acute periapical abscess of the right mandibular first molar. The patient underwent extraction and cyst enucleation. Gram negative bacilli isolated from blood culture on day 5 after admission were identified as Prevotella species. After receiving antibiotic treatment and undergoing dental procedures, the patient made a full recovery. We report on a case of septic shock due to infection by Prevotella species in association with an acute periapical abscess.

PURPOSE: We conducted a pilot study to investigate the effects of sleep patterns on wellness in interns working in the emergency department (ED). We also looked at various factors interns considered in deciding specialties and aspects of the ED they dislike, to collect the basic data necessary for quality improvement. METHODS: We conducted a prospective observational study of interns who worked a 25 h shifts every other day by evaluating various aspects of their ellness (stress, fatigue, burnout), using questionnaires and vital signs. The questionnaires were completed four times by each subject at each shift. In total, 62 interns were assigned to teams comprised of three interns each. Each team participated in the study four times each day, once every week for 4 weeks, yielding a total of 992 questionnaires to be analyzed. RESULTS: The participating interns were 26 years of age on average. Thirty-six (58%) were male, and twenty-six (41%) were female. Systolic and diastolic blood pressure (BP) both tended to fall as time passed, as demonstrated by relatively higher BP at 8 a.m. and 4 p.m., as compared to BP measured at 3 a.m. and 9 a.m. (systolic BP p=0.003, diastolic BP p<0.0001). Similarly, pulse rate was in the normal range at 8 a.m. and 4 p.m. but tended to fall from 3 a.m. to 9 a.m. (p<0.0001). Sleep at night-time after duty was positively correlated to the degree of stress, fatigue, and burnout, with longer night-time sleep resulting in higher scores for each. Four hours or more of daytime sleep also resulted in a statistically significant increase in stress and fatigue scores. CONCLUSION: More than 4 hours daytime sleep after duty resulted in more stress and fatigue the next day. An increase in night-time sleep as well as total sleeping hours positively correlated with and resulted in increased stress, fatigue, and burnout scores.

Carcinoid tumors of ampulla of Vater are rare and slow growing neoplasms that are composed of variable numbers of cells that contain endocrine secretory granules in their cytoplasm, which can be identified by immunohistochemistry, and electron microscopy. Symptoms of Carcinoid tumors of ampulla of Vater are jaundice, hemorrhage, abdominal discomfort, duodenal obstruction or carcinoid syndrome. The incidence of Carcinoid tumors of ampulla of Vater is 1% of all gastrointestinal carcinoid tumors in Western countries. We report a case of no recurrence for 53 months after pylorus preserving pancreaticoduodenectomy for carcinoid tumor of ampulla of Vater

PURPOSE: Necrotizing fasciitis is an uncommon soft tissue infection which spreads rapidly along subcutaneous fascial planes and produces overlying skin necrosis. We report a case of eyelid necrosis and periorbital necrotizing fasciitis. METHODS: A 64-year-old, previously healthy, male visited the emergency room complaining of acute facial edema. He had been using an ointment for itchy scalp lesion due to hair dye, and had multiple mosquito bites on his forehead. He took NSAIDs before the day of visit for headache. Physical examination showed erythematous swelling of soft tissue and tense fluctuant bullae on eyelid and periorbital area. On the 6th day of hospitalization bullae ruptured, and purplish discoloration and necrosis were noticed. RESULTS: Parenteral antibiotics and surgical debridement were applied. Wound cultures were positive for Staphylococcus aureus resistant to methicillin. Histology of the debrided tissue showed necrotizing inflammation. The full-thickness skin graft was performed over the exposed pretarsal and preseptal orbicularis muscle of the right eyelid. The skin defects were healed with the recovery of adequate eyelid function. CONCLUSIONS: We achieved satisfactory results with proper diagnosis and management such as parenteral antibiotics and surgical debridement in a case with eyelid and periorbital necrotizing fasciitis.

PURPOSE: To examine the trend, and investigated the possibilities as a prediction tool by choosing the trend score about male and urologic cancers have the high incidence rate. MATERIALS AND METHODS: We selected 5 major male and 3 major urologic cancers for past 3 years (from 2010 to 2012) and examined the incidence rate, and using Naver and Google trend, the rate of cancer incidence was compared with the trend score during the same period. RESULTS: From 2010 to 2012, the greatest occurrence of the cancer to males was the stomach cancer, followed by colon, lung, liver, and prostate cancer. In the urologic field, the prostate cancer was the first one, followed by kidney and bladder cancer. In 2010 to 2012, the Naver trend score was 32 for stomach and colon cancers, 31 for lung cancers, 20 for liver cancers, and 19 for prostate cancers, which index were corresponded with the order of incidence rate. Though the Google trend score for prostate cancer was not found, the average was 9 for stomach cancer, 8 for colon cancer, 6 for lung cancer, 4 for liver cancer, which index were corresponded with the order of incidence rate. In 2013 and 2014, the figure of prostate cancer was grown and exceeded liver cancer. CONCLUSIONS: In the trend score, the index of the prostate cancer shows continuing increase, and, from the results, urologists should recognize the importance of the study on the prostate cancer such as management, prevention, and treatment of the prostate cancer.
