To identify the efficacy of laparoscopic cholecystectomy, we retrospectively analyzed 600 cases of laparoscopic cholecystectomy who were treated at the Department of Surgery, Chung Ang University from September 1990 to December l992. We intentionally divided periods into 3 groups to observe the frequency of morbidity and mortality, early and late complications, duration of operation and postoperative hospitalization with accumulaton of surgical experiences and techniques. The most prevalent age group was 6th decades, male to female ratio was 1: 1.47 and associated diseases were hypertension, obesity, pulmonary tuberculosis in order of frequency and previous abdominal operations were appendectomy, TAH, C-section in order of frequency. The duration of operation was 38.6 minutes and postoperative hospitalization was 6.2 days. The most frequent pathologic diagnosis was chronic cholecystitis. The postoperative complications were noted in 15 cases(2.5%) including 5 cases of bleeding 4 cases of bile leakage. The number of patients who needed parenteral narcotics was decreased in later peiod. According to oral cholecystogram, opacification correlated with duration of operation of laparoscopic cholecystectomy.

PURPOSE: Pilomatrixoma is a benign, usually asymptomatic tumor. It presents clinically as a solitary superficial subcutaneous nodule measuring between 0.5 cm and 5 cm in diameter on the head or upper extremeties and has not been reported after skin graft. The objective of this article is to report our experience in treating pilomatrixoma which occurred after split thickness skin graft on the lower extremity. METHODS: A 56-year-old female was treated in August 2005 with a 0.5 X 0.5 cm firm subcutaneous nodule at recipient site of split thickness skin graft on the left medial thigh. The tumor was successfully removed by complete excision and histologic examination was followed. RESULTS: The diagnosis was pilomatrixoma which was characterized by a dual population of proliferating basophilic cells and diagnostic shadow cells. CONCLUSION: The tumor was successfully treated by complete resection. The authors report this very rare case of pilomatrixoma which occurred at recipient site of split thickness skin graft.

BACKGROUND/AIMS: Imrnortalized human fetal liver cell lines established by transfecting simian virus 40 T gene wae found to lose differentiated liver cell functions in successive long-term culture. Butyrate, known as a differentiation-promoting agent for a variety of cancer cell lines, is produced in the colon by bacterial flora and selectively transported into the liver though the portal blood flow. Therefe, butyrate might play a role in the maintenance of differentiation in hepatocytes in vivo. In thepresent study, the effects of butyrate on cell growth and differentiation in human fetal liver cell lines was investigated. METHODS: Human fetal liver cell lines imrnortalized by SV 40 T antigen were treated with sodium butyrate (1mM), and cell growth rate after butyrate treatment were nmsured by the number of viable cells, determined by trypan blue dye exclusice method. The effects of sodium butyrate on the hepatocyte-specific differentiatian were assessed by albumin and alfa-fetoprotein (AFP) mRNA expression, analyzed using reverse-transcription polymerase chain reaction, and were also by the increment of albumin secretion into culture media, determined by a competitive inhibition ELISA. RESULTS: Treatment with sodium butyrate resulted in a cessation of cellular proliferation and alterations in cellular morphology (increased cell size and polygonal change in shape). The level of albumin mRNA after sodium butyrate treatment was elevated by about two times as compared to that of control. In contrast, AFP mRNA expression were dennstrated neither before nor after sodium butyrate treatment. The average amount of albumin released in the medium was less than 6pghnl/10'cells/2days in the absence of sodium butyrate, and increased to 17 p g/ml/10'cells/2days at day 2, 21ugfml 10'cells/2days at day 4 in the presence of sodium butyrate, and these levels thereafter were over 10 times higher than that in the absence of sodium butyrate until day 10. CONCLUSION: These mults indicate that treatment of immcetalized fetal liver cell lines with butyrate leads to inhibition of cellular proliferation and promotion of adult hepatocyte-specific differentiation.

BACKGROUND/AIMS: Lens culinaris agglutinin-A reactive alpha-fetoprotein (AFP L3) has been reported to be highly specific for the diagnosis of hepatocellular carcinoma (HCC). The present study was to evaluate the clinical usefulness of AFP-L3 for the diagnosis of HCC in the patients either with chronic liver disease or with HCC in complete remission who showed significant increment of serum AFP level and no mass lesion in the liver on ultrasonography. METHODS: A total numer of 34 patients (24 with chronic liver disease, 10 with HCC in complete remission) were enrolled, who showed significant increment of serum AFP level and no mass lesion in the liver on ultrasonography. Serum AFP L3 levels were analysed by AFP differentiation kit L. Abdominal spiral CT or ultrasonogram was performed at 1-3 month intervals and all of the patients were followed up for more than 6 months. RESULTS: Among 24 patients with chronic liver disease, two were positive (higher than 15%) for AFP L3; however, HCC was not detected in these patients, while HCCs were detected in two of 22 patients negative for AFP L3 during followe-up. Eight of the 10 patients with HCC in complete remission were positive for AFP L3; recurrent HCCs were detected in 7 of those 8 patients as well as in the rest 2 patients negative for AFP L3 during follow-up. The overall sensitivity and specificity of AFP L3 measurement for the detection of HCC within 6 months of follow-up were 63.6% and 87.0%, respectively. The positive and negative predictive value for HCC in patients with chronic liver disease were O% and 90.9% and for recurrent HCC in HCC patients in remission were 87.5% and ON, respectively. CONCLUSION: The measurement of AFP L3 is suggested to be useful for the diagnostic strategy in patients either with chronic liver disease or hepatocellular carcinoma in complete remission, who showed progressive increment of serum AFP level and no mass lesion in liver on ultrasonogram.

BACKGROUND: The prevalence of dementia is estimated to be as high as 11.3% among coummunity-dwelling persons over 65 years of age in Korea. The fear of dementia for both patients and families is growing because of the chronicity and progressiveness of the disease. Though the recognition, evaluation, and management of patients with dementia are important for the care of older pateint, unfortunately, MMSE takes 5 to 10 minutes to administer and is cumbersome to carry for all elderly patients in busy office. The Clock Drawing Test has been known as valid, easily administered and low cost screening procedure for the congnitive impaiment associated with dementia in general geriatric clinic population. In this study, we assessed the usefulness of this measure as a screening test for dementia, on the basis of the correlation between clock drawing and MMSE-K. METHODS: The subjects for this study consisted of 47 elderly who visited to two elderly clubs in Seoul from April 1996 through June 1996 or the outpatient department of Family medicine of the Ehwa Mok-dong hospital. They received the Mini-Mental Status Exam and the Clock Drawing test. Three observers evaluated them by ratings from 10(best) to 1(worst). Inter-rater reliability of scores from the Clock Drawing Test was assessed and Pearson correlation coefficients were used to examine the relationships between scores from the Clock Drawing Test and MMSE-K. RESULTS: Their mean age was 75.4 years with range of 65 to 91 years. There were 34 women and 13 men. Correlations between individual raters was highly significant(y=0.8939, 0.8552, and 0.8698, respectively ; P<0.01). Compared to scores on MMSE-K, rating from clock drawings by each of 3 raters revealed statistically significant correlations(y=0.7164, 0.7398, and 0.6884, respectively ; P<0.01). CONCLUSIONS: The clock drawings can be rated reliably by even untrained observers and performance on this task relates significantly to performance on MMSE-K of severity. We confirmed the usefulness of clock drawings as a simple, easily administered, low cost, and reliable general screening tool for dementia in a general geriatric clinic population.
