A Case of Colchicine-Induced Neutropenia in Liver Cirrhosis Patient.: Ho Chan Lee, Heon Ju Lee, Yong Gil Kim, Jae Hyun Park, Sung Joon Kim, Jun Seok Park; Yeungnam Univ J Med. 2009;26(2):125-129. Published online December 31, 2009; DOI: https://doi.org/10.12701/yujm.2009.26.2.125

Abstract PDF: Colchicine is an alkaloid that has been used for treating acute gouty arthritis, psoriasis, scleroderma and Behcet's syndrome. Colchicine decreased liver fibrosis in rats with carbon tetrachloride induced cirrhosis and in patients with many liver diseases. Therapeutic oral doses of colchicine may cause nausea, vomiting, abdominal pain and diarrhea. The adverse effect of colchicine associated with the dose is bone marrow suppression, and especially neutopenia. Neutropenia has often been reported in patients have taken an overdose of colchicine. We describe a 64-year-old female liver cirrhosis patient with neutropenia that was induced by a therapeutic dose of colchicine.

A Case of Jejunal Diverticula Which Caused Massive Small Bowel Bleeding.: Ho Chan Lee, Byung Ik Jang, Jae Hyun Park, Sung Joon Kim, Jun Seok Park, Sang Hoon Jung; Yeungnam Univ J Med. 2009;26(2):120-124. Published online December 31, 2009; DOI: https://doi.org/10.12701/yujm.2009.26.2.120

Abstract PDF: Gastrointestinal bleeding is a common cause of hospitalization. Jejunal diverticula is a rare disease and it is an unusual cause of obscure gastrointestinal bleeding. After exclusion of the more common bleeding sources, small bowel diverticula should be considered as a possible rare cause of gastrointestinal bleeding. Jejunal diverticular bleeding is difficult to diagnose and treat because the bleeding site cannot be identified by routine endoscopy and radiologic studies. An exploratory operation is sometimes needed to diagnose and treat obscure gastrointestinal bleeding. If the bleeding site is certain, then surgical resection of the bleeding part of the bowel is the procedure of choice. We report here on a case of jejunal diverticular bleeding that was diagnosed by and treated with surgical resection.

Colon Cancer with a Nonspecific Inflammatory Colonoscopic Finding.: Jae Hyun Park, Byung Ik Jang, Ho Chan Lee, Sung Joon Kim, Jun Seok Park; Yeungnam Univ J Med. 2009;26(2):114-119. Published online December 31, 2009; DOI: https://doi.org/10.12701/yujm.2009.26.2.114

Abstract PDF: Colon cancer is the second most common malignancy in Korea. It is classified as superficial type, the mass type, the ulcerative type, the ulceroinfiltrative type, the diffuse infiltrative type and the unclassified type according to the colonoscopic findings. We report here on a case of colon cancer that was initially misdiagnosed as acute infectious colitis at the initial presentation. A 64-year-old man visited to Yeungnam University Hospital for watery diarrhea and lower abdominal pain. Colonoscopy revealed long segmental edematous mucosa and hyperemic mucosa with stenosis in the transverse colon. He was diagnosed as having acute infectious colitis according to the colonoscopic finding. However, two days later after colonoscopy, he visited the emergency room for hematochezia. We performed computerized tomography(CT) and obtained blood samples to find the origin of the bleeding. We found thickening of the transverse colon lumen and ascites on the CT finding and an elevated level of tumor markers; we also obtained the results of the colonoscopic biopsy that was done via colonoscopy. He was finally diagnosed as having colon cancer with carcinomatosis, a poorly differentiated adenocarcinoma.

Ulcerative Colitis Mimicking Acute Hemorrhagic Colitis.: Hee Jung Moon, Byung Ik Jang, Sung Bum Kim, Ho Chan Lee, Jae Hyun Park, Jong Ryul Eun, Tae Nyeun Kim; Yeungnam Univ J Med. 2008;25(2):182-186. Published online December 31, 2008; DOI: https://doi.org/10.12701/yujm.2008.25.2.182

Abstract PDF: Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract that affects the large bowel. Its etiology remains controversial. However, an infectious or immunologic origin is considered the primary cause. The onset of UC is typically slow and insidious, but some patients may present acutely with symptoms mimicking infectious colitis. We report a case of ulcerative colitis mimicking acute hemorrhagic colitis at initial presentation. A 60-year-old man was referred to Yeungnam University Hospital for bloody diarrhea and abdominal pain. Sigmoidoscopy revealed mildly edematous mucosa in the rectum and hyperemic mucosa with petechiae in the sigmoid colon. The patient was treated with antibiotics for several days, and his symptoms improved. However, after one month, his bloody diarrhea relapsed. Follow-up sigmoidoscopy revealed mucosal friability in the rectum and sigmoid colon. He was diagnosed with ulcerative colitis, and his symptoms were improved with mesalazine and a steroid enema.

A Case of Hepatocellular Carcinoma with intradural growth Presenting as Obstructive Jaundice.: Sung Bum Kim, Tae Nyeun Kim, Sung Jun Kim, Ho Chan Lee, Jae Hyun Park, Jong Ryul Eun, Byung Ik Jang, Heon Ju Lee, Sung Su Yun, Young Kyung Bae; Yeungnam Univ J Med. 2008;25(2):165-170. Published online December 31, 2008; DOI: https://doi.org/10.12701/yujm.2008.25.2.165

Abstract PDF: The incidence of hepatocellular carcinoma presenting as obstructive jaundice is 0.7~9%. The mechanisms of obstructive jaundice include bile duct invasion by tumor, tumor thrombi, blood clots, direct bile duct compression by tumor, and intraductal tumor growth. We report a rare case of hepatocellular carcinoma with intraductal growth. A 46-year-old woman was admitted due to colicky right upper abdominal pain and jaundice for 4 days. Computed tomography showed dilatation of the left intrahepatic duct, and endoscopic retrograde cholangiography showed a filling defect in the left main intrahepatic duct. We performed a left lobectomy with a Roux-en-Y hepaticojejunostomy. The tumor was diagnosed as a hepatocellular carcinoma with intraductal growth.

Detection Rate of Extended-Spectrum beta-Lactamase Producers in Klebsiella pneumoniae and Escherichia coli Isolated at Yeungnam University Medical Center.: Chae Hoon Lee, Ho Chan Lee, Kyung Dong Kim, Tae Su Lee; Yeungnam Univ J Med. 1999;16(2):270-276. Published online December 31, 1999; DOI: https://doi.org/10.12701/yujm.1999.16.2.270

Abstract PDF: BACKGROUND
Extended-spectrum beta-lactamases(ESBL) are enzymes that confer resistance to oxyimino-beta-lactams as well as to penicillins and cephalosporins. Strains of Klebsiella pneumoniae and Escherichia coli that produce ESBL have been increasingly prevalent in many countries. The purpose of this study was to investigate the ESBL production rate of K. pneumoniae and E. coli at the in Yeungnam University Medical Center. MATERIALS AND METHODS: Thirty-one isolates of K. pneumoniae and twenty-five isolates of E. coli were examined for ESBL by double disk synergy test, using 20/10microgram ticarcillin/clavulanic acid and 30microgram oxymino-beta-lactam(ceftazidime, ceftriaxone and aztreonam) disks. RESULTS: Fifty-two percent of K. pneumoniae and sixteen percent of E. coli isolates revealed double disk synersism. Majority of ESBL-producing strains(fifty-five percent) were isolated from patients in the intensive care unit. CONCLUSION: ESBL production of K. pneumoniae and E. coli were also common at the Yeungnam Univercity Medical Center and pose a serious problem for antimicrobial therapy.
