ABSTRACT
BACKGROUND: Diabetic nephropathy has long been known as most common culprit of ESRD. In NIDDM, histopathologically intrarenal hemodynamic changes are nonspecific, frequently with global glomerulosclerosis, interstitial fibrosis, tubular atrophy and severe arterosclerosis. Duplex renal Doppler sonography is useful in the noninvasive assessment of intrarenal hemodynamic change and Doppler indices reflect increased renal vascular resistance. So we compared the values of R.I. and P.I., in NIDDM patients, with several clinical parameters to identify that R.I. and P.I. values can reflect increased renal vascular resistance and predict diabetic nephropathy as early markers. METHODS: Renal Doppler US scan was performed on 40 patients with NIDDM to obtain Doppler signals from arcuate artery or interlobar artery and thereby calculate the R.I. and P.I. From every each individual, clinical and laboratory data including age, sex, morbidity period, BMI, mean blood pressure, total cholesterol, serum creatinine, BUN, HbA1c, 24 hr urine protein and creatinine clearance were analyzed. We analyzed the correlation between values of R.I. and P.I. with clinical parameters by using univariate and multiple linear regression analysis. The patients were classified as three groups on the basis of the amount of 24 hour urine protein and value of serum creatinine : Group 1(n=15) was defined as patients with 24 hr urine protein less than 150mg/day and serum creatinine less than 1.5mg/ dL, group 2(n=12) as between 150mg/day and 500mg/ day and serum creatinine less than 1.5mg/dL and group 3(n=13) as more than 500mg/day or serum creatinine above 1.5mg/dL. RESULTS: 1) R.I. values showed correlation with age, morbidity period, mean blood pressure, HbA1c, serum creatinine, BUN, creatinine clearance and 24 hour urine total protein. P.I. values showed correlation with age, morbidity period, mean blood pressure, serum creatinine, BUN, creatinine clearance and 24 hour urine total protein. 2) R.I. and P.I. values were significantly affected by creatinine clearance and age in multiple regression analysis. 3) There were statistically positive correlation between 24 hour urine protein and R.I. and P.I.. But when we divided into three groups based on their amount of 24 hour urine protein. R.I. didn't show statistical correlation but P.I. showed significant correlation in the group of patients with proteinuria over 500mg/day(p<0.05). CONCLUSION: Renal doppler indices reflect increased renal vascular resistance in NIDDM patients and correlate with clinical parameters of diabetic nephropathy. We suggest that the R.I. and P.I. are useful marker for indicating diabetic vascular complication in NIDDM patients. However, further comparative studies should be carried out to elucidate the usefulness of R.I. and P.I. as early markers or advantaging parameters in predicting diabetic nephropathy.

BACKGROUND: A esophagogastroduodenoscopy is now considered to be one of the essential rnethods for diagnosis of upper gastrointestinal disease. Furthermore early detection of stomach cancer by such a mass screening techique is very important to increase the survival rate. METHODS: A clinical analysis was conducted on 9,137 healthy subjects who had undergone a gastrofiberscopic examination for the secondary prevention, from January 1995 to December 1996, in Kangbuk Samsung hospital. RESULTS: 1) Number of cases with normal finding was 764 (8.4%). 2) The most prevalent disease found was chronic gastritis (82%). The number of cases with superficial gastritis was 64.7%, erosive gastritis 9.0%, atrophic gastritis 6.4% and metaplastic gastritis 1.6%. Atrophic and metaplastic gastritis were more frequent in the older age group. 3) The prevalence of peptic ulcer was 13.9% and duodenal ulcers (8.1%) was more common than gastric ulcers (5.8%, p<0.05) with a male to female ratio of 3.7: 1, and 2.1: 1 respectively. 4) Of the 10 cases with stomach cancer (0.11%), 5 cases (0.055%) were found to be advanced stomach cancer and the other 5 cases (0.055%) were early gastric cancer. The macroscopic type of early gastric cancer was type IIc in 4 cases and type IIb in another case, and 4 cases were limited in mucosa but another was in submucosa. The size of 4 cases were below 1 cm and there was no lymph node metastasis. CONCLUSION: Medically screened subjects were found to have many abnormalities, and therefore, it is recommanded that regular check ups using an endoscopy would be needed for early detection of early gastric cancer regardless of clinical symptoms.

BACKGROUND/AIMS: Changes in subsite distribution of colorectal cancer have been shown in recent years. The carcinoma tend to shift to more proximal colon and this proximal shift is influenced by age and sex. This study was designed to delineate the relationship of age to subsite incidence of colorectal cancer and to define the role of gender in this difference. METHOD: We have analyzed the data by patients with colorectal cancer from 1985 to 1995 for elucidate the relationships between age, sex and prinmry location of colorectal cancer. 749 patients(male 454, female 295) were diagnosed of colorectal cancer performed by colonoscopy and/or sigmoidoeopy were divided into three groups by their location of cancer (Right colon: appendix, ascending colon, hepatic flexure, T-colon proximal 2/3 Left colon: T-colon distal 1/3, splenic flexure, descending colon, sigmoid colon Rectum: rectum). RESULTS: 1) The mean age of all patients was 53.84 +/- 13.11(yr). Mean ages of Right colon, Left colon, and Rectal cancer group were 55.54 +/- 14.12, 55.32 +/- 12.51, 52.22 +/- 13.09(yr), respectively. The mean age of Right colon and Left colon cancer group is significantly older than that of Rectal cancer group (p=0.0040, p=0.0042). 2) Infemale age group over 56, mean age of Right colon cancer group is shown to be 3.35 and 4.82 years older than Left colon cancer group and Rectal cancer group, respectively (p=0.0062, p=0.0053) and Colon cancer tend to develop on more right side according to increase in age. 3) Above correlation was not observed below 55 of both sexes and male age group over 56. 4) No significant differences in histological differentiation and tumor stage were observed among the three groups. 5) The study was conducted to evaluate the difference in the location of colorectal cancer between two following groups; The first group diagnosed from 1985 to 1990 and the second group from 1991 to 1995, yet significant statistical difference was not observed. CONCLUSION: Age increase seems to show correlation with right shifting of colon cancer, and this correlation was most significant in old women age group. This finding suggests unknown factor strongly linked to age and sex might play important role in carcinogenesis of colorectal cancer.

Background: Whole body scan using 131-iodine is performed to detect local recurrence or metastasis after thyroidectorny in differenciated thyroid cancer patients. The sensitivity of this procedure is related to the dose of radiopharmaceutical administered. It was reported that 131I posttreatment whole body scan demonstrate foci of tracer uptake not previously observed in diagnostic scan in 10~30% of cases. Posttreatment scans were most likely to reveal new foci in young patients(<45) and patients who had previously received radioactive iodine therapy. Method: We observed the frequency of discordant posttreatment scans and analysed the clicnical significance in 33 differenciated thyroid cancer patients who were admitted for radioiodine ablation from June, 1995 to April, 1996. Results: In 7 cases(21.2%), post treatment scan demonstrated cme or more foci of uptake and revealed less sites of uptake than diagnostic scan in 3 cases(9.1%). In one case with elevated thyroglobulin level and negative diagnostic scan, post treatment scan revealed new uptake sites with thyroid bed and cervical 1ymph node. The sites of discordant uptake were cervical lymph nodes in 4 cases and rnediastinal lymph node in one case, lung in one case, thyroid bed and cervical lymph nodes in one case, 3 cases of 7 pts(43%), demonstrated ane or more foci of uptake in post treatment scan, had history of previous radioiodine treatent. Conclusion: Post treatment scan confirmed uptake into remnant and metaststic tissues identified on the corresponding low dose diagnostic scans. Scanning after high dose radioiodine treatment frequently demonstrated one or more foci of uptake, especially in patients with previous radioiodine treatment, which were not visualized on the diagnostic low dose scan. Treatment scan may be useful for detection of remnant tissue or metastatic lesion in patients with elevated thyroglobulin and negative diagnostic scan.

Cushing's syndrome associated with nodular adrenal glands will be divided into four main categories: adrenal adenoma, adrenal carcinoma, primary pigmented nodular adrenal dysplasia (PPNAD) and macronodular adrenal hyperplasia(MAH). The term macronodular adrenal hyperplasia is restricted to the presence of multiple nodules visible to the naked eye, ranging in size from 0.5 to 7.0 cm. We report a case of Cushings syndrome caused by bilateral macronodular adrenal hyperplasia (MAH). A 45-year-old man presented with Cushingoid features, hypertension and diabetes mellitus. Urine free cortisol was 449.9 mmol/day(27-276) and were not suppressed after administration of low-dose and high-dose dexamethasone. Plasma ACTH was very low(1.87 pmol/L(18)) and was not stimulated by administration of ovine CRH. In abdominal CT, both adrenal glands were markedly enlarged and nodular in appearance. Pituitary MRI showed no abnormal finding. Bilateral adrenalectomy was done. Histologic examination revealed multiple nodules and internodular hyperplasia. This case and other reports suggested that because of variable biochemical, radiologic and pathologic findings, macronodular adrenal hyperplasia represents a heterogeneous group of patients with varying degrees of adrenal autonomy.
