PURPOSE: we clinically measured the temperature rise in real time and analyzed the difference of albino rabbit and pigmented rabbit in use of the specially designed thermometer. METHODS: Specially designed thermometer was attached into the subretinal pigment epithealial and choroidal space through the suprachoroidal space in three pigment and three albino rabbits, with diode laser of 810 nm wave length, 3 mm spot size. We examined the retinal temperature according to laser irradiance power at each ten seconds during sixty seconds and the laser power setting was 200 mW, 300 mW, 400 mW in pigmeted rabbit and 300 mW, 600 mW, 800 mW in albino rabbit. We analyzed the results based on the measurements at least three times per each irradiance power. RESULTS: In albino rabbit, the maximal range of retinal temperature change was 1.2 degrees C and 1.7 degrees C in 300 mW and 600 mW, 14.1 degrees C in 800 mW power of 810 nm diode laser irradiance. In pigmented rabbit, the maximal range of retinal temperature change was 12.1 degrees C in 200 mW of laser irradiance power, 16.2 degrees C in 300 mW, 24.3 degrees C in 400 mW during sixty seconds in 810 nm diode laser. CONCLUSIONS: We investigated the ratinal temperature at transpupillary thermotherapy in 810 nm wavelength diode laser on rabbits. The difference of retinal temperature change was in accordance with the amount of chorioretinal melanin pigment. Therefore if the laser power setting used in caucasians would be attempted in orientals, it is the point to be considered during transpupillary thermotherapy.

The recurrence of viral hepatitis B or C after liver transplantation is almost universal but their clinical courses and outcomes are vary widely. We investigated four cases of rapidly progressive and fatal recurrent viral hepatitis following liver transplantation, which were rapidly progressive and fatal. Case 1 was a 58-year-old male, who developed recurrent viral hepatitisC. Case 2, 3, and 4 were a 59-year-old female, a 42-year-old male, and a 50-year-old male, respectively, who developed recurrent viral hepatitis B. In cases 1 and 2, the histopathological features of the first liver biopsies were prominent ballooning degeneration of the hepatocytes but later biopsies revealed significant lobular activity. Case 3 began with a marked fatty change and mild lobular and porto-periportal activity and progressed to severe lobular activity and septal fibrosis. In case 4, the first liver biopsy revealed minimal lobular activity but the second biopsy revealed severe lobular activity.

BACKGROUND: The optimal screening tools for hepat ocellular carcinoma are regular tests of alpha fetoprotein (aFP)and liver ultrasonography every 6 months in high risk group. To implement successful long-term project for reducing cancer-mortality,it is essential to know the reasons f or non-compliance among the high risk group. METHODS: A telephone survey was done a mong the hepatitis B surface antigen positive patient group who had not receiveda follow-up test of aFP and liver ultrasonography. This group was selected among the patients who had received health examinations from January,2002 to December,2002 at a university hospital center for health promotion, and the reasons for non-compliance were inquired. RESULTS: There were no stati stical di fferences i n educational level,economic status,age,and sex between the patient group who had taken appropriate follow-up tests and the group who had not. But there were statistically significant differences in the admission history and t ransf usi on hi st ory bet ween t he t wo groups. The reasons for non-compliance were as follows:1. ignorance to the significance of follow-up examination (41.7%),2.lack of time (27.8%),3.no specific signs of cancer (22.2%),4.high costs (5.6%),and 5.fear of discovering serious disease. CONCLUSION: It is important to have patients educated on the significance of screening and early diagnosis of hepatocellular carcinoma.

OBJECTIVE: To evaluate the changes of gait patterns during crossing obstacles of different heights in hemiplegic stroke patients and to compare gait characteristics with those of healthy control subjects. METHOD: Subjects were 13 hemiplegic stroke patients and 9 age-matched healthy adults. Subjects stepped over obstacles with each height of 3, 8 and 13 cm. The three- dimensional gait analysis was performed. Temporospatial, kinematic and kinetic parameters were measured in both lead and trail limb. The pre- and post-obstacle distance, pre- and post-obstacle swing time and toe clearance were also measured. RESULTS: With increase in height of obstacles, ratio of single limb support time, angle of hip, knee flexion in swing phase and hip extensor moment increased in both lead and trail limbs. In the lead limb, post-obstacle distance and toe clearance also increased (p<0.05). Compared with control groups, the angle of knee flexion, hip extensor and hip flexor moment and pre- and post-obstacle distance decreased significantly in the lead limb of hemiplegic patients (p<0.05). In the trail limb of hemiplegic patients, the angle of hip flexion, hip flexor moment and post-obstacle distance decreased (p<0.05). CONCLUSION: Understanding strategies for adequate control and coordination of the swing limb during crossing obstacles may be the basis for the safe training of obstacle crossing in hemiplegic stroke patients.

BACKGROUND/AIMS: The aim of this study was to evaluate the efficacy of lamivudine in patients with HBeAg-negative and HBV DNA-positive chronic liver disease. METHODS: Twenty-four chronic liver disease patients were enrolled whose serology had common characteristics of HBeAg (-), and anti-HBe (+) but HBV DNA (+). All had elevated alanine aminotransferase (ALT) levels. 150mg of lamivudine was given orally once daily for more than 6 months. The goal of this treatment was the elimination of HBV DNA in serum and normalization of ALT level. Once HBV DNA disappearance and ALT normalization were observed, lamivudine was continued for two additional months. HBeAg, anti-HBe, HBV DNA and ALT were followed up every 1-2 month during, and after, treatment. RESULTS: Median duration of treatment was seven months. HBV DNA became undetectable after a median one month of treatment and ALT activity was normalized in all 24 patients within six months. Among the sixteen patients who were followed for more than 12 months after cessation of treatment, six relapsed. The cumulative relapse rate at 12 months was 37.5%. CONCLUSION: Lamivudine suppresses HBV replication effectively and normalizes serum ALT in patients with HBeAg-negative and HBV DNA-positive chronic liver disease. The relapse rate after cessation of treatment seems to be relatively low.

PURPOSE: Acute renal failure (ARF) is one of the common complications after liver transplantation (LT) and could be fatal unless promptly treated. Identification of risk factors is needed to prevent ARF and to attenuate the unfavorable outcomes of ARF after LT. The aim of this study was to analyze risk factors for development of postoperative ARF (between day 0 and day 30 after LT). METHODS: Total 72 LTs were performed between 1996 and 2005. Sixty six patients' records, excluding 6 patients with preoperative serum creatinine level more than 2.5 mg/dl, were reviewed retrospectively for preoperative, intraoperative, and postoperative variables to compare patients presenting ARF with the remaining patients. RESULTS: Postoperative ARF occurred in 36 transplants (54.5%) after LT. Preoperative serum sodium, bilirubin and BUN, creatinine level were higher in ARF group. ARF group had more child-pugh class C, and more episodes of preoperative hepatic encephalopathy. During intraoperative period, anhepatic time was longer and total doses of intraoperative furosemide was larger in ARF group. Also, postoperative blood immunosuppressant level was higher, and postoperative episodes of bleeding and hypotension were more common in ARF group. In multivariate analysis, preoperative child-pugh class C (P=0.041), preoperative serum creatinine level (> or =1.0 mg/dL, P=0.032), and postoperative episodes of hypotension and bleeding (P=0.045, P=0.03 respectively) were identified as risk factors for postoperative ARF. CONCLUSION: This study showed that preoperative renal and liver function, and postoperative hemodynamic condition were independent risk factors for development of ARF after LT.

OBJECTIVE: To evaluate the level of depression, anxiety and quality of life in primary caregivers for the severe stroke patients. METHOD: We studied a sample of 44 severe stroke patients and their primary caregivers. Functional status of the severe stroke patients was evaluated by Modified Barthel Index (MBI). We collected the data through interviewing the caregivers and using the Beck Depression Inventory (BDI), State- Trait Anxiety Inventory (STAI), Ego-strength scale, Short Form Health Survey-36 (SF-36) and Family APGAR (Adaptation, Partnership, Growth, Affection and Resolve) score. RESULTS: The average level of depression in caregivers was low. The mean socres of STAI were 41.5 for state anxiety and 44.3 for trait anxiety, respectively. Ego-strength scale was significantly inversely related to BDI score and trait anxiety inventory score, but positively related to SF-36 score. The most influencing factor for the SF-36 score was the BDI score. CONCLUSION: Primary caregivers for the home-bound severe stroke patients demonstrated a lower level of quality of life, especially mental health, general health and vitality component. Community based rehabilitation should more focus on the evaluation and support for caregiver's psychologic status and their quality of life.

We here report two cases of combined liver-kidney transplantation in patients with both end stage renal disease and hepatitis B related liver cirrhosis. The first case was a 55-year-old man with hepatitis B related liver cirrhosis and chronic renal failure, who received cadaveric liver and kidney transplantation. Immunosuppressants were cyclosporine, prednisolone, and mycophenolate mofetil. Clinical course was uneventful except for hemolytic anemia due to alloimmunization that occurs after ABO-mismatched solid organ transplantation. Hemoglobin level became stable after plasmapheresis. His renal and hepatic function is maintained up to the present time. The second case was a 42-year-old man with nephrotic syndrome and liver cirrhosis. The patient underwent living related-combined liver-kidney transplantation. Donors were his son and brother. Blood type of the patient and donors were identical and the result of HLA crossmatch was negative. On the 14th postoperative day, stenosis at anastomotic site of hepatic artery was detected. After balloon angioplasty hepatic function was normalized. At 8 months after the transplantation, the patient is stable without adverse events.

BACKGROUND/AIMS: Fibroblast growth factor signaling is involved in hepatocarcinogenesis. The aim of this study was to determine the fibroblast growth factor receptor (FGFR) isotype expression in hepatocellular carcinoma (HCC) and neighboring nonneoplastic liver tissue, and elucidate its prognostic implications. METHODS: Immunohistochemical staining of FGFR1, -2, -3, and -4 was performed in the HCCs and paired neighboring nonneoplastic liver tissue of 870 HCC patients who underwent hepatic resection. Of these, clinical data for 153 patients who underwent curative resection as a primary therapy were reviewed, and the relationship between FGFR isotype expression and overall survival was evaluated (development set). This association was also validated in 73 independent samples (validation set) by Western blot analysis. RESULTS: FGFR1, -2, -3, and -4 were expressed in 5.3%, 11.1%, 3.8%, and 52.7% of HCCs, respectively. Among the development set of 153 patients, FGFR2 positivity in HCC was associated with a significantly shorter overall survival (5-year survival rate, 35.3% vs. 61.8%; P=0.02). FGFR2 expression in HCC was an independent predictor of a poor postsurgical prognosis (hazard ratio, 2.10; P=0.02) in the development set. However, the corresponding findings were not statistically significant in the validation set. CONCLUSIONS: FGFR2 expression in HCC could be a prognostic indicator of postsurgical survival.
