PURPOSE: Recently, we have noticed an increase in the number of patients with mumps in Incheon, Korea. The aim of this study is to estimate the regional trend in mumps incidence and to evaluate the factors related to the recent increase. METHODS: We reviewed the medical records of 66 patients with mumps who had been admitted to Incheon St. Mary's Hospital from July 1999 to June 2009. We compared the differences in records between "outbreak, 2009" and "nonoutbreak, 2000-2008." RESULTS: Of the 66 patients, 35 (53%) were admitted in 2009, and 31 (47%) were admitted between 2000 and 2008. Most of the patients admitted during the outbreak were over 15 years of age (80.0%), were born before 1993 (77.1%), and had received a single dose of mumps vaccine (62.9%). There were no significant differences in contact history, present address, clinical manifestations, and complications, except for orchitis, between the two groups. CONCLUSION: There was a sharp increase in the number of inpatients with mumps who were born before 1993 and who were over 15 years of age. We recommend that a booster vaccination be considered for adolescents and young adults born before 1993 who are susceptible to mumps infection due to their reduced opportunities for receiving two doses of mumps vaccine.

This study was performed to find out the influences of ethanol on the metabolism of trichloroethylene(TRI) in rats. TRI in corn oil at the dosage of 150, 300, 600 mg/kg was injected peritoneally once a day for two days to two groups. In one group ethanol(4 g/kg) was taken orally 30 minutes before TRI injection, and the other group ethanol was not. The results of experiments are as follows: 1. The contents of cytochrome P-450 and b5 had inverse relationship with in-jected TRI amounts in both groups. 2. The activity of NADPH P-450 reductase was decreased slowly in TRI injected group related with TRI amount, but decreased drastically in the group pretreated with ethanol. 3. The activity of NADH b5 reductase had relationship with injected TRI amount, but the statistical significance was found only in the groups of 300 and 600 mg/kg of TRI injected without relevance to ethanol when compared with the group that was not injected. 4. The activity of ADH was more decreased and ALDH activity was more increased in groups that TRI injected and ethanol was pretreated with ethanol groups than in group without any treatment. These results suggest that ethanol may inhibit epoxide formulation, the first step or TRI metabolism, and change from TCE-OH to TCA also.

PURPOSE: In the treatment of breast cancer, neoadjuvant chemotherapy (NAC) is useful to reduce breast cancer size before surgical intervention. Patients who achieve a pathologic complete response (pCR) to NAC have improved overall survival (OS). However, the relationship between prognosis and partial response is yet unclear. In this study, we evaluated prognostic factors and the tumor response ratio (TRR) method among patients who received NAC. METHODS: Clinicopathologic factors were evaluated to predict OS. The TRR was calculated by dividing pathologic tumor size by clinical tumor size. TRRs were then categorized into four groups, and the survival times for the different TRR groups were compared using statistical evaluation. RESULTS: Clinical N stage (p=0.02), overall stage (p=0.04), pathologic N stage (p=0.03), hormone receptor status (p=0.01), and lymphovascular invasion (p=0.02) were significantly associated with OS. Pathologic overall stage and TRR did not correlate with OS. Patients with a pCR exhibited the best survival rates using the current staging system and the TRR method. CONCLUSION: Clinicopathologic factors can be easily applied to predict OS, and clinicians could use these parameters until an accurate, simple, and highly discriminatory methods is developed to assess breast cancer patients with a partial.

Objectives: This study investigated the effects of mouthwashes containing cetylpyridinium chloride and zinc acetate on oral health. Methods: A total of 60 participants were included in the study. Fifty-three participants (27 and 26 participants in the experimental and control groups, respectively) were retained, excluding seven candidates who dropped out. The mouthwash used for the study was spat out after 10-15 ml of mouth-washing for 3 s in the oral cavity after breakfast, lunch, and dinner. Oral examination indices included the gingival (gingival index, PMA index), the patient hygiene performance (PHP index, Turesky plaque index), and the bad breath (BB checker, Oral chroma) indices. Five measurements were taken after 2, 4, 6, 8, and 12 weeks and compared. Results: Measurements of the gingival index showed a statistically significant difference between the experimental and the control groups after 4 weeks, and the PMA index from eight weeks (P<0.05). Measurements of the PHP and Turesky plaque indices showed a significant difference in the experimental and control groups after 4 weeks (P<0.05). Compared to the PHP index before the experiment, that of the experimental group showed a significant index decrease after 2 weeks (P<0.05). Results of measuring bad breath through a BB checker showed a statistically significant difference between the experimental and control groups after 4 weeks (P<0.05). Conclusions Oral mouthwash products containing cetylpyridinium chloride and zinc acetate relieves gingivitis, removes bacterial plaque, and reduces bad breath.

PURPOSE: This study was designed to assess the clinical manifestations and the effect on prognosis of seizures in children with acute lymphoblastic leukemia(ALL). METHODS: The study group consisted of 20 patients(10 males and 10 females) who experienced seizures out of the 198 pediatric ALL patients(117 males and 81 females) who were diagnosed and treated at the Department of Pediatrics, St. Mary's Hospital, the Catholic University of Korea. RESULTS: The overall incidence of seizure developing after the diagnosis of ALL was 10.1% and in 11 patients(5.6%), seizure recurred one or more times. An average of 6.5+/-3.6 months(range 0-42 months) elapsed between the beginning of treatment and the new onset of seizures. In 13 patients(65%), the first seizure occurred during the induction or re-induction chemotherapy phase. Seizure type was partial seizure in 11 patients(55%), and generalized seizure in 9 patients(45%). In 15 patients(88.2%), brain imaging study showed abnormal findings and in 18 patients(90%), EEG revealed abnormal findings. 11 patients were diagnosed with epilepsy and were treated with long-term anticonvulsants. In these patients, 4 patients(36.4%) had no seizure recurrence, but 2 patients(18.2%) showed no response to anticonvulsants. The 5-year survival rate of the patients experiencing seizures was 47%, while the rate was 78% for those did not experience seizures (P<0.001). CONCLUSION: Seizures in pediatric patients with ALL was closely related to the 5-year survival rate. Therefore, these patients require early careful observation, evaluation and intensive care. Also, further studies such as ways to diminish the side effects of antileukemic agents are necessary to reduce the risk of seizure.

Thrombotic complications in iron-deficiency anemia (IDA) are rare. We now report a case of deep vein thrombosis following iron deficiency anemia in cerebral palsy. A 20 year old male was admitted to our hospital? due to a pale appearance. He was diagnosed as having spastic cerebral palsy. On admission, a complete blood cell count showed IDA with thrombocytosis. Prothrombin time and activated partial thromboplastin time were within the normal range. We observed swelling and edema on the left thigh and ankle without tenderness. We performed Doppler sonography and computed tomography. Thrombi were located in the left common iliac vein and left superficial femoral vein with elevated D-dimer levels. We started heparin therapy. We excluded intravascular hemolysis or a hypercoagulable state when we found that Ham's test, anti-cardiolipin antibody, and lupus anticoagulant were negative. The patient died due to hypoxemia and cardiac failure despite ventilator care with anti-coagulant therapy.

BACKGROUND AND OBJECTIVES: Alpha lipoic acid (ALA) is beneficial for improving endothelial dysfunction and preventing atherosclerosis-related diseases. We evaluated the affect of ALA on stent restenosis in a porcine model. MATERIALS AND METHODS: The First experiment: Balloon overdilation injuries were performed in two coronary arteries in 12 pigs. Four weeks after the balloon overdilation injury, 24 bare metal stents were placed for 24 injured coronary arteries. We randomized into two groups (12 stents per group; control group: aspirin and clopidogrel only, ALA group: aspirin and clopidogrel plus 100 mg/kg ALA during 4 weeks). The Second experiment: Stents were randomly implanted in 2 coronary arteries in 8 pigs. Group I was the control stent group (n=8), and group II was the ALA coated stent group (n=8). Follow-up coronary angiogram and histopathologic assessment were performed at 4 weeks after stenting in both experiments. RESULTS: The First experiment On histopathologic analysis, the injury score and internal elastic lamina area did not differ significantly between the two groups. The neointimal area was 7.3+/-0.9 mm2 in the control group and 2.2+/-1.1 mm2 in the ALA group (p<0.001), and the histopathologic area of stenosis was 75.9+/-8.5% in the control group and 23.5+/-10.5% in the ALA group (p<0.001). The Second experiment: The injury score and internal elastic lamina area were not significantly different between the two groups. The neointimal area was 7.4+/-1.1 mm2 in the control group and 1.4+/-0.8 mm2 in the ALA group (p<0.001), and the histopathologic area of stenosis was 77.6+/-10.9% in the control group and 15.6+/-7.6% in the ALA group (p<0.001). CONCLUSION: Both a high dose of oral ALA and ALA coated stents inhibited neointimal hyperplasia in this porcine coronary artery stent restenosis model.

PURPOSE: Remnant gastric cancer (RGC) are generally detected at advanced stages or infiltration of adjacent organs. We retrospectively reviewed the surgical outcomes and clinicopathologic results of remnant gastric cancers that have operated during fourteen years in one institution of Korea. MATERIALS AND METHODS: 34 patients who were diagnosed with RGC at Ajou University Hospital from April 1995 to October 2009 were enrolled. We analyzed the features of previous operation, and according to these results, surgical outcomes and clinicopathologic results for RGC were analyzed. RESULTS: Of 34 patients, 20 patients had previously undergone distal gastrectomy for malignant disease, and 14 patients for benign disease. The period between previous operation and surgery for RGC in the patients underwent operation for malignant disease was shorter than that in benign patients (P<0.001). In surgical field, 31 patients (91.0%) were resected and curative resection was possible in 23 patients (67.6%). When 31 patients who underwent resection for RGC were divided into previous malignant and benign disease, there was no significantly different in terms of surgical outcomes and pathologic findings between two groups. Meanwhile, the patients who recently (after 2005) underwent surgery for RGC showed less advanced stage compared with the patients who underwent surgery before 2004. CONCLUSIONS: Resection was possible in the higher proportion (91.0%) of patients diagnosed with RGC compared with previous reports. The cause of previous operation did not effect on the surgical outcomes for surgery of RGC. Recent trend of RGC is to increase the proportion of early stage gastric cancer. Therefore, surgeons should consider curatively surgical resection for RGC the regardless of pattern of previous operation.

In this study we evaluated the influence of both the thickness of residual enamel and the color of the composite resins applied to lingual surface on the labial surface color. Background plates were made by randomly (A1, A2, A6D, B1, B2, B3, C1, C2, C6D) selected colors of Filtek Supreme (3M ESPE, St. Paul, U.S.A.) composite resin. Crown portion of 9 maxillary central incisors were cut off and embedded with acrylic resin except labial surface. Samples of average thickness of 2.2 mm were obtained after cutting it in a thickness of 2.5 mm from the labial surface and sandpaper polish. The shade of composite resin background was measured using Spectrophotometer (Spectrolino(R) GretagMacbeth, Regensdorf, Switzerland). And CIE L*a*b* value of 2.2 mm thickness tooth samples were measured on the 9 composite resin backgrounds. And then, the cutting side of tooth samples was ground to the extent of 1.9 mm, 1.6 mm, 1.3 mm, 1.0 mm and placed on composite resin backgrounds and measured L*a*b* values with the same method. In all samples, L* value and b* value seemed to have a tendency of decreasing as thickness of tooth sample becomes thinner regardless of background colors (p < 0.05). But, a* value didn't show the significant differences depending on the thickness.
