Open bite is accompanied by decrease in tooth contact and overbite, and causes collapse of occlusal plane, mastication difficulties, speech disorders, changes in appearance, and lower occlusal force than normal. Open bite caused by temporomandibular joint disorder in adults with complete occlusion must be corrected after removal or stabilization of the causative factors. Orthodontic treatment, occlusal adjustment, prosthetic treatment, and surgical treatment can be the option of occlusal correction. This report describes about estimating the cause of occlusion change in two patients who developed an open bite due to mandibular displacement in adults with complete occlusion and different treatment approaches accordingly. In one patient, satisfactory result was obtained in functional and esthetic aspects through occlusal adjustment after stabilization of the temporomandibular joint.

BACKGROUND/AIMS: Despite improvements in surgical techniques and postoperative patient care, bile leakage can occur after hepatobiliary surgery and may lead to serious complications. The aim of this retrospective study was to evaluate the efficacy of endoscopic treatment of bile leakage after hepatobiliary surgery. METHODS: The medical records of 20 patients who underwent endoscopic retrograde cholangiopancreatography because of bile leakage after hepatobiliary surgery from August 2009 to September 2014 were reviewed retrospectively. Endoscopic treatment included insertion of an endoscopic retrograde biliary drainage stent after endoscopic sphincterotomy. RESULTS: Most cases of bile leakage presented as percutaneous bile drainage through a Jackson-Pratt bag (75%), followed by abdominal pain (20%). The sites of bile leaks were the cystic duct stump in 10 patients, intrahepatic ducts in five, liver beds in three, common hepatic duct in one, and common bile duct in one. Of the three cases of bile leakage combined with bile duct stricture, one patient had severe bile duct obstruction, and the others had mild strictures. Five cases of bile leakage also exhibited common bile duct stones. Concerning endoscopic modalities, endoscopic therapy for bile leakage was successful in 19 patients (95%). One patient experienced endoscopic failure because of an operation-induced bile duct deformity. One patient developed guidewire-induced microperforation during cannulation, which recovered with conservative treatment. One patient developed recurrent bile leakage, which required additional biliary stenting with sphincterotomy. CONCLUSIONS: The endoscopic approach should be considered a first-line modality for the diagnosis and treatment of bile leakage after hepatobiliary surgery.

PURPOSE: This study was undertaken to evaluate the gastroduodenal pathology and Helicobacter pylori infection in children with upper gastrointestinal symptoms. METHODS: One hundred and seven pediatric patients with upper gastrointestinal symptoms were undergone endoscopy at the Gyeongsang National University Hospital from June 1990 to April 1991. Histopathologic examination was done by H & E staining of gastric antral biopsy specimen and gastritis was defined according to the Sydney System. Tissue H. pylori status was evaluated with the urease test using Christensen's urea broth and H & E or Warthin-Starry silver staining of gastric antral biopsy specimen. IgG Immunoblotting were also performed to detect specific anti-H. pylori antibody in these patients. RESULTS: The reasons for endoscopy were recurrent abdominal pain, acute abdominal pain, sallow face, hunger pain, and frequent nausea. Variable degrees of gastric mucosal hyperemia were found in most of the patients. Gastric hemorrhagic spots, gastric ulcer, duodenal ulcer, duodenal erosion, and hemorrhagic duodenitis were rare endoscopic findings. Histologic chronic gastritis was found in 88% of 107 patients. Histologic chronic duodenitis was observed in all 99 patients whose tissue were available. Gastric tissue H. pylori was positive in 57% of 107 patients by one of the ureasetest, H & E staining and Warthin-Starry silver staining. However, gastric tissue H. pylori detection rate was lower in the younger age groups. Anti-H. pylori IgG antibodies were detectable in 96% of 107 patients. CONCLUSION: Chronic gastroduodenitis and anti-H. pylori IgG antibody were ubiquitous in children with upper gastrointestinal symptoms.

OBJECTIVE: To determine whether polymorphisms of the Vitamin D receptor (VDR)gene,known to be associated with osteoporosis and/or osteoarthritis (OA) in Caucasians,might also relate to the risk of OA and osteoporosis in Korean postmenopausal women METHODS: A population of 130 postmenopausal women,including 76 healthy controls and 54 knee OA patients,were studied using anteroposterior radiographs of the knee,which were graded for OA according to the Kellgren classification system.The VDR genotype was determined by using polymerase chain reaction and by digestion with the three restriction enzymes Taq I,Bsm I,and Apa I.Femoral neck bone mineral density (BMD)was assessed in all participants by dual energy X-ray absorptiometry . RESULTS: VDR genotype frequency distributions in Koreans were much different from Caucasian's both in the OA group and the control group.Especially, "t t", "B B" and "A A" genotype were very rare,prominently differentiating from Caucasians.But within Koreans,no significant differences in VDR genotype frequencies were observed between OA cases and controls.VDR genotype was not significantly associated with the radiographic grades of OA.And there were no significant relationships of VDR genotype with BMD scores in each group. CONCLUSION: In Korean postmenoposal women,the VDR gene polymorphisms do not significantly contribute to an increased prevalence of knee OA or to differences in BMD.VDR genotype analysis would not be helpful for assessing the risk of knee OA in Koreans because :(1)there is no correlation of VDR genotypes with the radiographic severity of OA ;and (2)there is a more skewed distribution of VDR genotypes in Korean population compared to the Caucasian's .

BACKGROUND: The purpose of this study was to determine whether the distribution of vitamin D receptor (VDR) polymorphisms in rheumatoid arthritis (RA) patients group is different from that of the control group and whether there is a relationship between VDR genotype and radiographic severity or bone mineral density (BMD) of RA patients. METHODS: The VDR genotype was determined by polymerase chain reaction and digestion with three restriction enzymes Taq I, Apa I and Bsm I in 78 healthy women and 97 female RA patients. Hand X-rays were scored by Larsen's method and bone mineral density was measured by dual energy X-ray absorptiometry (DEXA) in RA patients. RESULTS: VDR genotypic distributions in Koreans were much different from Caucasians in each control and RA patient groups. Especially, "tt" allele and "BB" allele were very rare, prominently differentiating from Caucasians. But within Koreans, no significant difference of VDR genotypic frequency was observed between control group and RA patients group. And there was no significant relationship of VDR genotype with radiographic scores, nor with BMD scores in RA patients. CONCLUSION: The distribution of VDR polymorphisms in Korean RA patients was not different from controls. The VDR polymorphisms correlate neither with the radiographic severity of RA, nor with BMD scores in Korean RA patients.

OBJECTIVE: To determine the correlation between total anti-oxidant capacity (TAOC)and lipid peroxidase (LPO)levels in serum and disease activity in systemic lupus erythematosus (SLE). METHODS: The study population consisted of 99 patients with SLE according to the 1982 revised ACR criteria and 83 healthy controls.The serum TAOC levels in 99 patients with SLE and 83 healthy controls by the ABTS(R) inhibition method (Randox Ltd,Antrim,UK)and serum malondialdehyde (MDA)levels in 37 out of 99 patients with SLE were measured.Anti-dsDNA antibody (anti-dsDNA),albumin,AST,ALT,cholesterol,uric acid and creatinine were mea-sured to determine the association with the serum TAOC levels.The correlation between the serum TAOC levels and nephritis in 27 cases with nephritis out of 99 SLE patients was also investigated.The SLE disease activity was determined by the SLE disease activity index (SLEDAI)at the time of sample collection. RESULTS: Compared to the controls (1.37 +/- 0.127mmol/L),serum TAOC levels were significantly decreased (1.29 +/- 0.124mmol/L)in SLE patients (p=0.001). And there was a negative correlation between serum TAOC levels and SLEDAI total scores in the SLE patients (r=-0.388,p=0.0001),but no significant correlation between TAOC levels and C3 and anti-dsDNA.Further,a significant difference (p<0.04)in TAOC levels was found in SLE patients with and without nephritis.In comparison with other parameters such as AST,ALT,and cholesterol which might change anti-oxidant level,there was no correlation between the serum TAOC levels and them,except for serum uric acid (r=0.387, p=0.0001),creatinine,and albumin (r=0.507,p=0.0001).Additionally,we couldn't find significant correlation between the serum TAOC levels and MDA. CONCLUSIONS: The serum TAOC levels correlate significantly with SLE disease activity and are associated with nephritis.Also,this study showed a significant correlation with serum albumin levels in these patients.Conclusively,the measurement of the serum TAOC levels in patients with SLE will provide useful information on SLE disease activity.

A study on fibronectin, which is synthesized in response to inflammatory process of joint destruction, can be of great value in identifying the mechanism of inflammation or disease activity of rheumatoid arthritis (RA). This study attempts to measure the concentrations of total fibronectin in synovial fluid of patients with RA and osteoarthritis (OA), and compare it with the clinical disease activity parameters of RA available. A total 68 patients suffering from knee pain and joint effusion was examined. Synovial fluids of thirty-eight RA patients and thirty OA patients were measured by using monoclonal fibronectin antibody. Cross-sectional analysis was undertaken to correlate the fibronectin levels of the RA patients with the clinical disease activity parameters available. RESULTS: 1. Mean synovial fibronectin level of RA (148.4+/-72.6 microgram/ml) was significantly higher than that of OA (39.5+/-16.9 microgram/ml)(p<0.001). 2. The fibronectin levels in RA do not seem to have significant relationship with the parameters such as disease duration, the duration of morning stiffness, Ritchie index, ESR, CRP, and rheumatoid factor. CONCLUSION: In conclusion, the synovial total fibronectin concentration can clearly distinguish RA from OA. However, it would be unlikely to be used as a parameter of disease activity.

BACKGROUND: Thirty children ranging from 3 to 15 years of age underwent cardiac valve replacement at Dongsan Medical Center from 1982 to 1997. MATERIAL AND METHOD: There were 16 boys and 14 girls. The mean age was 12.1. The underlying pathological cause for valve replacement was congenital heart disease in 17 children and acquired heart disease in 13. The valve replaced was mitral in 15 children, aortic in 11, tricuspid in 3, and combined aortic and mitral in 1. Twenty-one mechanical and 10 tissue valves were placed: primary mechanical valve have been utilized since 1985. Eight of ten patients with tissue valves have had successful second valve replacements 4 to 11 years after the initial operation. RESULT: The operative mortality was 6.7%, but mortality was higher among patients less than 5 years of age and patients who had previous cardiac operations. Of the 28 operative survivors, 4 patients were lost to follow-up: the remaining patients were observed for a total of 2091 patient/months(mean 74.7 months, maximum 187 months). There was one late death from dilated cardiomyopathy after mitral valve replacement in 7 year-old patient with atrioventricular septal defect. After the operation, all patients with mechanical valves were placed on a strict anticoagulant regimen with Coumadin. The actuarial survival rate was 96% at the end of the follow-up. No instance of thromboembolism or major bleeding were observed in the survivors. CONCLUSION: These results indicate that valve replacement can be performed with low mortality in children, and with satisfactory long-term survival.
