Periodontal supporting tissue goes through destruction by chronic inflammatory periodontal disease as two aspect. One is qualitive aspect such as alteration of periodontium, the other is quantitative aspect such as alveolar bone loss. According to many authors, PDL is responsible for biting force, and there are two means for measuring PDL's function - mobility test and biting force test. This study was conducted to compare the biting force with remaining bone level, that is, quantitative aspect of periodontium, in anterior and premolar teeth at periodontal maintenance phase. 17 patients on periodontal maintenance phase during 6 months at minimum were selected for this study. For the same condition, 4 anterior, canine, premolar teeth were tested by MPM-3000 bite-force register at the same time(a.m.10-12), the same position, the same posture, by the same examiner. Patients of TMD, ill-fitting prosthesis, general disease, malocclusion and the teeth of TFO, absence of opposing teeth, malposition were excluded. Remaining bone level was measured on the panorama X-ray film through 5 level from 1mm below CEJ to root apex. Teeth were examined twice, and bigger one was selected. If the values showed large difference, examinatin was re-done and the mean was selected. The results were as follows ; 1. In the 4 anterior group, as the remaining bone is decreased, the average of maximal biting force is decreased. Especially, at 3/5 bone level, maximal biting force is decreased significantly(p<0.01). 2. In the canine group, as the remaining bone is decreased, the average of maximal biting force is decreased. Especially, at 2/5 bone level, maximal biting force is decreased significantly(p<0.01). 3. In the premolar group, as the remaining bone is decreased, the average of maximal biting force is decreased. Especially, at 3/5 bone level, maximal biting force is decreased significantly(p<0.05). From the results of this study, clinicians could utilize these efficiently when they have to determine the proper restorative materials, time for tooth extraction. treatment plan, prognosis.

Portal flow steal occasionally persists even after the liver transplantation, which may reduce the portal flow and thus threaten the patients' outcome. Therefore, pre- and peri-operative detection of portal steal phenomenon requiring radiological or surgical interruption is essential for the liver transplantation candidates as well as for the recipients.

A newly developed third generation enzyme immunoassay(Lucky HCD 3.0 EIA) for hepatitis C virus(HCV) antibodies was added with the envelope(E1E2)/NS4 fusion proteins and expanded NS5 proteins as well as the core/NS3 fusion proteins. Authors evaluated the HCD 3.0 EIA with the previously available second generation EIA(HCD 2.0) in 10,435 Red Cross blood donors. Among 10,435 donors who were screened for the presence of HCV antibodies by HCD 2.0 assay, 22(0.21%) sera were repeatedly reactive. All of these sera were tested for further testing. Only 13 of all tested sera were reactive by HCD 3.0 EIA, and nine sera were not reactive. Nine of 13 HCD 3.0 positive sera were reactive by recombinant immunoblot assay(Lucky-Confirm). Also seven of these 13 sera had detectable HCV genomic RNA by reverse transcriptase-polymerase chain reaction(RT-PCR). None of nine HCD 3.0 negative samples had detectable immunoblot assay and HCV genomic RNA. It is concluded that the new HCV EIA can decrease a significant false positivity of second generation EIA in a blood donor population. This new assay correlates well with detection of HCV-RNA by RT-PCR and identifies donors who are truly infected.

PURPOSE: To assess the role of the preoperative portal vein embolization (PVE) in patients in need of major hepatectomy. MATERIALS AND METHODS: Total of 11 cases consisted of Klatskin tumor (n:6), gallbladder cancer (n=2), and hepatocellular carcinoma (n=3). After percutaneous transhepatic puncture of portal vein (right:7, left:4), the embolization of 1st order branch of right portal vein was done with Gentamicin soaked Gelfoam cubes. Radiologically, the angle between the middle hepatic vein and the inferior vena cava was measured on pre- and post-PVE CT (F/U :10 days) to evaluate the hypertrophy of the left lobe. Clinically, amount and nature of the drained bile through the PTBD tube of both lobes were analyzed in 5 patients with Klatskin tumor. The interval between PVE & operation was 10-24 days. Operative findings & the changes of postop. total bilirubin were analyzed and the complication after procedure was checked. RESULTS: There was decrease in mean angle between the middle hepatic vein and the inferior vena cava from 35.9 degree to 23.9 degree, but it was insignificant statistically (p=0.09). The embolization of right portal vein was done and there was increase in amount of drained bile from the nonembolized left lobe by 2-3 folds 8-14 days after PVE. The color and consistency between both lobes were significantly different; right lobe was darker in color and softer in consistency. Postoperative total bilirubin increased by 2-3 folds 1 to 4 days after PVE and normalized 10 to 14 days after PVE. Most of the patients had mild abdominal pain and fever after PVE and 1 patient had localized hematoma at puncture site which was subsided spontaneously. CONCLUSION: The preoperative portal vein embolization is a useful method for minimizing postoperative liver failure in patients in need of major hepatectomy.

IgA nephropathy can occur rarely as a complication of D-penicillamine treatment, but it is exact pathogenesis remains unclear. If a patients has gross or microscopic hematuria during D-penicillamine treatment, D-penicillamine induced IgA nephropathy should be suspected as a cause of hematuria. In those cases, renal biopsy should be taken for diagnosis and proper management. We experienced a case of IgA nephropathy confirmed by renal biopsy in a 39-years-old female patient with scleroderma during D-penicillamine therapy and report this case with a review of literature.

A buttonhole deformity of the finger is characterized by flexion of the pmximal interphalangeal joint and hyperextension of the terminal interphalangeal joint. When the central slip of the extensor tendon and the triangular ligament are ruptured,(or severed) on the base of the middle phalanx, buttonhole deformity will result.This article is based on clinical and follow up studies of 5 patients with buttonholedeformities. Five cases were treated by the modified Littler method and were followed from 4 months to 24 months postoperatively and good results were obtained in all cases.

Synovial chondromatosis is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue which disintegrates into the joint and continues to grow. Of the eight cases of synovial chondromatosis seen by the authors, three cases involved the knee, two of these were bilateral, three cases involved the elbow, one the hip joint and one the proximal phalanx of the right middle finger. The diagnosis of synovial chondroamtosis was made by histopathological findings of the excised mass. Most synovial chondromatosis cases obtained favorable results by removing masses from the joint and at the same time performing a partial synovectomy, except one case in which degenerative arth ritis had developed proeoperatively.

Systemic amyloidosis is an uncommon disease characterized by deposits of fibrillar aggregates of monoclonal immunoglobuloin light chains in vital organs. This amyloid deposit cause cardiac or renal dysfunction and ultimately, death. Cardiac amyloidosis may be asymptomatic or important causes of progressive heart failure and refractory arrhythmia. Cardiac involvement from AL amyloidosis is rapidly fatal. The amyloidoses are classified according to the biochemical nature of the fibril-forming protein. Cardiac amyloidosis is common in primary (AL) and heterofamilial amyloidosis and very rare in the secondary (AA) form. As we experienced a case of systemic amyloidosis affected heart, liver and kidney, which was confirmed by histology. We present a 57-year-old female case with literature review.
