OBJECTIVE: The aim of this study was to investigate the experimental brush wear pattern of a light cured surface sealant, Biscover (Bisco, Schaumburg, IL), and to evaluate its cariostatic effect. METHODS: Caries- free human premolars were used for the Biscover coating group (n = 90) and the control group (n = 10). The Biscover coating group was randomly assigned to nine subgroups of 10 each and the control group was assigned to two subgroups of 5 each according to the number of brushing strokes. An experimental 3-body wear test was conducted under different strokes of wear test. Tooth-brushing was accomplished with movement of each brush head set at a frequency of 100 rpm under a force of 1.5 N. Surface roughness was tested before, and after Biscover coating, and after brushing. Then, each of the 10 teeth of both groups were placed in artificial caries inducing solution for 7 days. All tooth surfaces were assessed using scanning electron microscopy. RESULTS: Biscover coated surfaces showed a smoother texture than enamel surfaces. The roughness was increased after experimental brushing and after 10,800 brushing strokes, the whole layer of Biscover wore out. However, teeth in the Biscover coating group had a cariostatic effect in cariogenic conditions. CONCLUSIONS: We suggest that white lesions in orthodontic patients can be suppressed by topical applications of Biscover.

Brain abscess is a rare, extremely aggressive, life-threatening infection. It may occur following : infection of contiguous structure, hematogenous spread, or cranial trauma/ surgery. Dental pathology and/or treatment have been linked to a small number of brain abscesses as possible source of infection. 50-year-old male patient was presented with a brain abscess caused by Streptococcus viridans. In the case presented, the significant oral findings were chronic periapical and periodontal infection due to root remnant of lower right 3rd molar. A case history and brief literature review of brain abscess related odontogenic infection was presented after successful treatment with antibiotics and craniotomy.

PURPOSE: The in vitro study suggested that proline to serine polymorphism in codon 475 (C1423T) of the A Disintegrin and Metalloprotease with ThromboSpondin type 1 repeats-13 (ADAMTS-13) gene is related to reduced activity of ADAMTS- 13. In this study, the frequency of the Pro475Ser polymorphism in Koreans was studied and plasma ADAMTS-13 activity was measured to find out whether this polymorphism contributes to decreased ADAMTS-13 activity in Koreans. PATIENTS AND METHODS: The frequency of the C1423T allele of the ADAMTS13 gene was studied along with measuring plasma ADAMTS-13 activity in 250 healthy Korean individuals. RESULTS: The allele frequency of C1423T polymorphism was 4%, and the median activity of CT type was 107 (69-143)%, which was lower than in controls with the CC genotype [118 (48-197)%, (p=0.021)]. CONCLUSION: Therefore, the Pro475Ser polymorphism seems to be popular in the Korean population, and attenuates ADAMTS-13 plasma activity.

Bilateral upper extremity amputee is rare and also complex, difficult process to apply the prosthesis to daily life. In Korea, there is no case report of bilateral myoelectric hand training, which is installed to bilateral upper extremity amputee due to electrical burn. We present usual 2 cases, who underwent bilateral transradial amputee, were fitted with a bilateral myoelectric prosthetic hand with an adaptive grip. It's not just long-term issues like the prosthesis prescription, but it is important functional problem whether or not to use actually. Especially the unique features of hand grasp function and writing can be the scale that measure recovery of the patient. The development of modern science and technology applications in clinical medicine cause the innovation of a prosthetic hand. In our two cases, good acceptance and functional improvement were noted. The information obtained in this case would be expected to be helpful in the bilateral amputee prosthetic prescription and training for their welfare.

OBJECTIVE: To assess the effectiveness of modified dynamic metacarpophalangeal joint flexion orthoses for treatment of post-burn hand contractures. METHOD: We enrolled 42 hand burn patients with limited range of motion at the metacarpophalangeal joints in this study. The patients were randomly assigned into either a control or an orthotic group. Both groups received the standard rehabilitation therapy focused on hand therapy; 21 subjects in the orthotic group wore a splint for 3 hours per day for 8 weeks. Hand function was measured by active range of motion, grip strength and other assessment tools. All parameters were estimated using the Mann-Whitney U test at the beginning and the end of the treatment after 8 weeks. RESULTS: The 21 subjects that had an orthotic intervention showed significant improvement in the range of motion at 2nd, 3rd, 4th and 5th metacarpophalangeal joints (p<0.05). However, the grip strength was not significantly increased after the 8 weeks of treatment compared to control group (p>0.05). There was a significant difference in the hand function scales between the 2 groups (p<0.05). CONCLUSION: The modified dynamic metacarpophalangeal joint flexion orthoses provide continuous flexion to metacarpophalangeal joint that is needed for the restoration of range of motion in post-burn hand contractures. For the clinical application of hand orthoses in patients with hand disorders, additional research into its affects are required.

BACKGROUND/AIMS: Hepatitis A is increasing during the recent years in Korea, and sporadic cases of hepatitis E are not rare. We investigated the etiology of acute viral hepatitis, including 27 cases of coinfection with hepatitis A and E, during the last 3 years. METHODS: Retrospective analysis of one hundred eleven patients with acute viral hepatitis at Chung-Ang University Hospital was done from January 2005 to July 2007. The patients were positive for any one of the following tests: IgM anti-HAV, IgM anti-HBc, HCV RNA and IgM anti-HEV. RESULTS: The proportions of acute viral hepatitis A, B and C were 94.6% (105/111), 4.5% (5/111) and 0.9% (1/111), respectively. Among the patients with hepatitis A, 27 patients (24.3%) were positive for IgM anti-HEV. We analyzed 105 patients with either hepatitis A only or they had coinfection of hepatitis A and E. The mean age, the duration of the hospital stay, the mean levels of serum transaminase, bilirubin and albumin and the protrombin time were similar between the patients with hepatitis A only and those with coinfection of hepatitis A and E. All the patients were discharged without serious complication such as fulminant hepatic failure. The biochemical liver function tests were normalized in all patients within 8 weeks. CONCLUSIONS: The most common etiology of acute viral hepatitis in Koreans was the hepatitis A virus. Patients coinfected with hepatitis A and E were observed. The patients with coinfection of hepatitis A and E showed no significant difference in their clinical features and laboratory parameters, as compared to the patients with hepatitis A only.

Diabetic gastroparesis is a pathologic condition of delayed gastric emptying with gastrointestinal symptoms such as nausea, early satiety and vomiting in the absence of mechanical obstruction in patients with diabetes mellitus. We report a case of diabetic gastroparesis who had diabetes mellitus for 13 years and suffered from nausea and vomiting with marked gastric dilatation of acute onset. Blood glucose level of the patient was very high and any mechanical obstruction was not found by gastroduodenal endoscopy, hypotonic duodenography, celiac angiography, electrogastrography and CT scan. Acute gastric dilatation was resolved with conservative treatment of gastric drainage, glucose control and hydration. Gastrointestinal symptoms of nausea and vomiting improved and diet was well tolerated thereafter.

BACKGROUND/AIMS: Diabetes mellitus (DM) is associated with an increased incidence of colon cancer. However, the relationship between DM and colorectal adenoma is not definite. In this study, we sought to determine the association between DM and the prevalence of colorectal adenoma. METHODS: We enrolled 606 patients with DM and 606 asymptomatic adults who underwent colonoscopy for routine health evaluations from June 2003 to June 2007. The frequency and characteristics of the colorectal adenomas were analyzed and compared between the two groups. RESULTS: The sex ratio and mean age were 1.67:1 (M:F) and 58.1+/-10.6 years, respectively, in patients with DM, and 1.68:1 and 57.6+/-8.9 years, respectively, in patients without DM, and these values were similar. The frequency of colorectal adenoma was 33.2% for the patients with DM and 32.3% for the patients without DM. The frequency, location, number, size and histopathologic findings of the colorectal adenomas were not different between the two groups. Among the patients with DM, the frequency of colorectal adenoma was 35.7% in the patients treated with oral hypoglycemic agents and 31.4% in the patients treated with insulin. Also, the other characteristics of the colorectal adenomas were not different according to the treatment method. CONCLUSIONS: The frequency and characteristics of colorectal adenomas were not different between the patients with and without DM.
