Recently, with the widespread use of new imaging techniques, the diagnosis of autosomal dominant polycystic kidney disease (ADPKD) is increasing. To analyze the extrarenal manifestations of ADPKD in Korean patients, we retrospectively studied the clinical characteristics of 30 patients with ADPKD. Thirty Patients with ADPKD who had been diagnosed at Yongdong Severance Hospital from 1988 through 1994 were recruited for this study. All patients' past and family histories were re-evaluated, and charts and radiologic images were reviewed retrospectively. The male to female ratio was 9:21, and the age of initial diagnosis was 39.2 +/- 13.8 (mean +/- SD) years. In 15 cases (50%), ADPKD had been diagnosed by renal symptoms; in 8 cases (26.7%), by chance during evaluation of extrarenal diseases; in 5 cases (16.7%), by family screening; and in 2 cases (6.7%), by uremic symptoms. Extrarenal involvement included hepatic cysts (70%), pancreatic cysts (16.7%), splenic cysts (6.7%), thyroid cysts (6.7%), inguinal hernia (3.3%), and colonic diverticula (3.3%). In 5 cases (16.7%), cardiac valvular abnormalities were noted by echocardiography. Seven patients underwent hemodialysis, and the duration from the initial diagnosis to initiation of dialysis was 9.9 +/- 8.5 (mean +/- SD) years. We investigated the extrarenal manifestations of 30 cases of ADPKD in Koreans, which were also common and clinically important as renal manifestations. Renal cysts are only one of a myriad of renal and extrarenal manifestations of ADPKD. ADPKD should be managed systematically since this disorder is a systemic disease with clinically important involvement of the cardiovascular system, the gastrointestinal tract, the genitourinary system, and the musculoskeletal system.

BACKGROUND: Little has been known about the incidence, the relationship with H. pylori infection and the prognosis of the multiple gastric polyposis. Recently, it was suggested that the eradication of H. pylori infection led the disappearance of the gastric polyps associated with H. pylori. We carried out a prospective study to determine the effect of H. pylori eradication on multiple gastric polyposis associated with H. pylori. METHODS: From July 1997 through August 2000, 13 patients who had multiple gastric polyposis on upper gastrointestinal endoscopy were recruited for this study. After eradication of H. pylori, we performed follow-up endoscopy at 2-3 months and 5-6 months later. RESULTS: The topographical distributions of gastric polyps were as following : antrum only in 7 cases, antrum and lower body in 4 cases, antrum and fundus area in 1 case, and entire stomach in 1 cases, respectively. The histopathological findings were as following : 13 cases showed chronic active gastritis, 2 cases with hyperplastic polyps, and 1 case with adenomatous polyps. After eradication of H. pylori infection, regression of multiple gastric polyps occurred in 7 cases (53.8%). In 7 cases with regression, regression was observed in 5 cases with chronic active gastritis alone, 1 case with hyperplastic polyps, and 1 case with adenomatous polyps. The re-biopsy specimens in 7 cases with regression revealed that the grade of inflammation decreased from 2.2 to 1.5 by the histological index of the updated Sydney system. CONCLUSION: With these results, we may conclude that the development of multiple gastric polyposis might be closely related with chronic H. pylori infection, and the eradication of H. pylori could lead to the regression of polyposis.

OBJECTIVE: The authors have aimed to compare the efficacy of the computed tomography with other study methods, and to investigate if replacement by computed tomography is possible METHODS: From January 1998 to December 2002, 203 cervical cancer patients underwent pre-staging studies including computed tomography. The positive predictive values, negative predictive values, sensitivity, specificity of each method of study were compared. RESULTS: 1. Compared computed tomography with intravenous pyelonephrography. Each values of computed tomography for hydronephrosis or non visualization of kidney were sensitivity 91.7%, specificity 97.8%, positive predictive values 84.6%, negative predictive values 98.9%. 2. Compared computed tomography with cystoscopy. Each values of computed tomography for bladder invasion were sensitivity 90%, specificity 95.8%, positive predictive values 52.9%, negative predictive values 99.4%. 3. Compared computed tomography with sigmoidoscopy. Each values of computed tomography for rectal invasion were sensitivity 80%, specificity 94.4%, positive predictive values 26.6%, negative predictive values 99.4%. CONCLUSION: Rather than routine examination for staging of invasive cervical cancer in all patients, it is more ideal to first take a non invasive technique. then perform on intravenous pyelonephrography, cystoscopy and sigmoidoscopy only in patient showing positive findings of hydronephrosis or non visualization of kidney, bladder or rectal invasion on computed tomography.
