The clinical feature of the muscle cramps and the effects of eperisone hydrochloride in treatment for the muscle cramps of the patients with liver cirrhosis / 대한내과학회지

BACKGROUND: Muscle cramps in cirrhotic patients are not serious symptoms but have frequently bad effect on their quality of life. We have evaluated the effectiveness of treatment with eperisone hydrochloride, an antispastic agent, on muscle cramps in cirrhotic patients. METHODS: Sixty five cirrhotic patients (cramps 35, no cramps 30) were included in our study. Thirty five patients with muscle cramps were questioned about the frequency and localization of muscle cramps. All patients were evaluated a physical findings and blood chemistry at the beginning of the study and after one month. Eperisone hydrochloride 50 mg per day were given orally to the patients with muscle cramps. RESULTS: There were significant differences for the number of diuretics use (p=0.019), hemoglobin (p=0.005), platelet (p=0.007), total bilirubin (p=0.003), albumin (p=0.000), total calcium (p=0.0001) and Na+ (p=0.001) between with and without muscle cramps. Muscle cramps were found to occur in calf muscles (60%) and hands (54%), to occur several times a week (76%), mainly during sleep (73%) and to last for several minutes (53%). After a month, muscle cramps completely disappeared in 7 patients (20%), decreased in frequency in 18 patients (51%) and were unaltered in 10 patients (29%). Side effects were observed in 7 patients (epigastric discomfort in five, fatigue in two) but any patients were not stopped. CONCLUSIONS: Eperisone hydrochloride was significantly effective in treatment for the muscle cramps of the patients with liver cirrhosis. In addition, this agents was well tolerated without any serious adverse effects in the majority of the patients.

Septic metastatic bilateral endophthalmitis complicating Klebsiella pneumoniae liver abscess in a non-diabetic woman / 대한내과학회지

Metastatic septic bacterial endophthalmitis is a rare but potentially devastating, serious disease. Endophthalmitis arising from Klebsiella pneumoniae liver abscess has been reported with diabetes mellitus as a major associated condition in Taiwan, but is rarely seen in patients without diabetes. There is often a delay in diagnosing endogenous bacterial endophthalmitis, particularly when there is no evidence of a primary infection or ocular infection is initial manifestation of sepsis. We report a non-diabetic patient with sepsis with right eye discomfort. Five days after admission, blood culture grew K. pneumoniae. Abdomen computerized tomography scan confirmed the presence of multiloculated liver abscess in right lobe. Despite intensive treatment, systemic and intravitreal antibiotics, liver abscess was resolved completely, but visual outcome was very poor. Physicians should be alerted to endogenous endophthalmitis in patients with Klebsiella septicemia, especially in diabetics with pyogenic liver abscess complains of ocular symptoms.

Long-term Outcome of Endoscopic Mucosal Resection for Gastric Adenoma and Factors Related to Recurrence / 대한소화기내시경학회지

BACKGROUND/AIMS: Endoscopic mucosal resection (EMR) has been known as a method of local treatment for early gastric cancer (EGC) or gastric adenoma. It has been widely accepted as a useful method due to its minimal invasiveness, safety and satisfactory result. The purpose of this study was to identify the factors affecting the recurrence after EMR. METHODS: Three hundred twenty adenomas in 297 patients were treated by EMR from January, 1991 until July 2003. Among those, 197 lesions in 184 patients that could have been followed-up were analyzed retrospectively. RESULTS: The mean follow-up period was 15.0 (1~89) months. Of the 197 lesions, there were 35 recurrences (17.7%). The recurrence rate was higher in lesions associated with severe mucosal atrophy and intestinal metaplasia in surrounding mucosa (p=0.035). Other factors showed no statistically significant difference in recurrence rate. CONCLUSIONS: In this study, we concluded that the presence of intestinal metaplasia and severe atrophic background mucosa were related to the recurrence of gastric adenoma after EMR.

Expression of Cyclooxygenase-2 and p53 Protein in Colonic Adenoma with Malignant Change / 대한소화기내시경학회지

BACKGROUND/AIMS: The aim of this study was to investigate the value of expression of COX-2 and p53 protein in colonic adenoma with or without malignant change. METHODS: We studied twenty-five cases of colonic adenoma with malignant change and twenty-five cases of colonic adenoma without malignant change treated by colonoscopic polypectomy in Chungnam National University Hospital from January, 1999 to July, 2002. We compared the expression of COX-2 and p53 protein by immunohistochemical stain in both group. RESULTS: In immunohistochemical staining, the expression of COX-2 was demonstrated 68.0% (17 of 25) of colonic adenoma with malignant change and not different with that of colonic adenoma without malignant change. The overexpression of p53 protein was detected immunohistochemically in 88.0% (22 of 25) of colonic adenoma with malignant change and 32% (8 of 25) of colonic adenoma only (p <0.05). CONCLUSIONS: The degree of COX-2 expression was similar in colonic adenoma and colonic adenoma with malignant change, but the expression of p53 in colonic adenoma with malignant change was significantly higher (p <0.05). These results suggest COX-2 might operate on early step of adenoma-carcinoma sequence. Also these results remind us that mutation of p53 gene operates on the late step of adenoma-carcinoma sequence.

Clinical Significance of Transiently Elevated Serum AFP Level in Developing Hepatocellular Carcinoma in HBsAg Positive-Liver Cirrhosis / 대한소화기학회지

BACKGROUND/AIMS: Serum alpha fetoprotein (alpha-FP) measurement has a limitation to detect hepatocellular carcinoma (HCC) because it is elevated in various liver diseases. Therefore, we studied the sensitivity and specificity of high alpha-FP in the diagnosis of HCC. METHODS: We studied 253 patients with HBsAg positive liver cirrhosis prospectively. We analyzed incidence of HCC related cut-off values of serum alpha-FP levels. During the follow-up period, we analyzed sensitivity and specificity of cut-off values of alpha-FP for the diagnosis of HCC, and alpha-FP elevation rate in relation to mass size. RESULTS: One hundred and twenty-five patients had a transient elevation of alpha-FP levels above 20 ng/mL. The corresponding incidences of HCC were 27.2% (34/125) and 15.6% (20/128 patients without elevation of alpha-FP), respectively with a statistically significant difference (p=0.03). Among 54 patients with HCC, 18 patients (33.0%) had levels of alpha-FP below 20 ng/mL on the time of diagnosis of HCC. When we defined cut-off values of serum alpha-FP as 20, 100 and 500 ng/mL, the corresponding sensitivity and specificity for HCC were 62.9% and 24.0%, 7.4% and 54.2%, 77.3% and 91.9%, respectively. We studied sensitivity according to cut-off values of alpha-FP defined as 20, 100, 200, 500 ng/mL in patients with small HCC below 2 cm. The corresponding sensitivity were 50.0%, 43.7%, 25.0%, 18.7%, respectively. In patients with levels of serum alpha-FP below 20 ng/mL, percentages of mass size less than 2 cm, 2~3 cm, 3~5 cm and more than 5 cm were 50.0%, 25.0%, 28.5% and 25.0%, respectively. CONCLUSIONS: We suggested that in order to detect HCC, careful periodic monitoring with alpha-FP, ultrasonography and abdominal computed tomography is needed in patients with HBsAg positive liver cirrhosis and whose serum level of alpha-FP is above 20 ng/mL.

A Case of Kaposi's Sarcoma of the Stomach and Duodenum in an AIDS Patient / 대한소화기내시경학회지

Kaposi's sarcoma, a rare tumor, usually presents itself with skin lesions. There is, however, an increased incidence in patients using immunosupressive drugs and with the acquired immunodeficiency syndrome (AIDS). Gastrointestinal Kaposi's sarcoma is usually asymptomatic, but may cause massive intestinal hemorrhage, perforation, intestinal obstruction, intussusception, protein-losing enteropathy, or sepsis. The gastroscopic appearances of Kaposi's sarcoma range from reddish purple maculopapules to polypoid, umbilicated nodule. In Korea, 3 case's of gastrointestinal kaposi's sarcoma have been reported so far. We experienced a 45-year-old man, who was positive for human immunodeficiency virus (HIV) antibodiy and developed Kaposi's sarcoma. A case of gastrointestinal Kaposi's sarcoma treated with paclitaxel is herein reported with the endoscopic findings before and after chemotherapy.

Retrospective Study on the Therapeutic Effects of an Etoposide, Adriamycin, Cisplatin-II (EAP- II) versus an Etoposide, Leucovorin, 5-Furorouracil (ELF) Combination Chemotheraphy in Unresectable Gastric Cancer

PURPOSE: The incidence rate and the mortality rate of gastric cancer have decreased in developed countries over the last several decades. On the other hand, they remain high in far eastern countries such as Korea, Japan, China and in many developing countries. The cure of patients with gastric carcinomas can be achieved mostly through complete surgical resection, but most gastric cancer patients are in advanced stages when diagnosed and have poor prognoses. therefore, the development of an effective systemic therapy is essential for far advanced gastric cancer patients. Until recently, the most commonly used combination chemotherapy was based on 5-flurouracil or cisplatin, but the results were not satisfactory, so recently etoposide, adriamycin and cisplatin (EAP-II) combination chemotherapy was introduced in patients with advanced gastric cancer. Early studies showed a high response rate and the ability to convert unresectable cases to resectable ones, but later studies couldn`t duplicate the result. the purpose of this study was to evaluate the relative efficacy&toxicity of EAP-II chemotherapy and ELF chemotherapy which is based on 5-flurouracil. MATENRIALS AND METHODS: Between July 1992 and July 2002, sixty-five patients with inoperable advanced gastric cancer were enrolled for this study. Thirty-seven patient received EAP-II chemotherapy:etoposide (20 mg/m2 IV for 1~5 days), adriamycin (20 mg/m2 IV for 1~5 days) and cisplatin (20 mg/m2 IV for 1~5 days) and Twenty-eight patients receieved ELF chemotherapy:etoposide (100 mg/m2 IV for 1~3 days), leucovorin (20 mg/m2 IV for 1~5 days) and 5-FU (500 mg/m2 IV for 1~5 days). Each treatment schedule for each group was repeated every four weeks: EAP-II means 3.4 cycles per patient: ELF means 4.1 cycles per patient RESULTS: Total respones rates were 5.4% in the ELF group and 3.6% in the EAP group (P-value>0.05). The median times to progression were 144 days in the ELF group and 92 days in the EAP-II group (P-value>0.05), and the median overall survival times were 189 days in the ELF group and 139 days in the EAP-II group (P-value>0.05). The difference in the survival curves for the two regimens was not statistically significant. Non-hematologic toxicitis&hematologic toxicitis were more frequently observed for the EAP-II regimen. Anemia: 27.6% in ELF vs 54% in EAP-II; Leukopenia: 8.5% in ELF vs 19% in EAP-II; nausea&vomiting: 45.9% in ELF vs 67.8% in EAP-II. CONCLUSION: EAP-II regimen is not superior to ELF regimen in the tratment of inoperable advanced gastric cancer.

CONCLUSION: EAP-II regimen is not superior to ELF regimen in the tratment of inoperable advanced gastric cancer.

Recent Changes of Organism and Treatment in Pyogenic Liver Abscess / 대한간학회지

BACKGROUND/AIMS: With the advance of antibiotics and the development of newer imaging techniques, marked changes in etiology, diagnosis, treatment and prognosis of liver abscess have been reported. METHODS: We reviewed the clinical data related to 94 patients with pyogenic liver abscess. RESULTS: Of the 94 patients in the study group, the male to female ratio was 1.4:1 and the peak incidence of liver abcess was in the 7th decade. About three quaters (74.5%) of the abcesses were of unknown origin. The predominant location was in the right lobe (70.3%). Single lesion was found in 80 patients and multiple lesions in 14 patients. Pathogens were identified in 67 patients, of which Klebsiella pneumoniae (65.7%) and E. coli (16.4%) were the most common. The modalities of treatment were percutaneous drainage with antibiotics (73.4%), percutaneous aspiration with antibiotics (16.0%), or antibiotics alone (8.5%). The case fatality rate, mainly from associated underlying diseases, was 9 cases (9.6%). Associated diseases were diabetes mellitus (14.9%) and malignancy (10.6%). CONCLUSIONS: Our study revealed that the most common organism was Klebsiella pneumoniae and percutaneous needle aspiration and/or catheter drainage were safe and effective treatment modalities for pyogenic liver abscess. Prognosis was determined by the underlying condition.
