Dieulafoy's lesion is an uncommon cause of gastrointestinal bleeding. Hemorrhage occurs through mucosal erosion from an abnormally dilated submucosal artery. Although Dieulafoy's lesion is usually located in the stomach, it may occur anywhere in the gastrointestinal tract. We report here on a case of jejunal Dieulafoy's lesion presenting as a mass and short segment stricture on CT and enteroclysis.

Chylopericardium is a rare clinical entity in which chylous fluid accumulates in the pericardial cavity. We report a case of primary idiopathic chylopericardium associated with multiple, small cervicomediastinal cystic hygromas occurring in an asymptomatic 43-year-old woman with no history of trauma, thoracic surgery, malignancy, infection or tuberculosis. Echocardiography showed a large amount of pericardial effusions and pericardial fluid analysis revealed inappropriately elevated triglyceride. We did not demonstrate communication between the thoracic duct and the pericardial sac by lymphangiography and chest computed tomography. She successfully responded to 30 days of continuous pericardial drainage and 15 days of a medium-chain triglyceride diet after 30 days of total parenteral nutrition. Follow-up echocardiography 6 months after treatment commencement showed a minimal reaccumulation of pericardial fluid without symptom. We conclude that if a patient is asymptomatic and can well tolerate daily life, surgery including pericardiectomy or ligation of the thoracic duct is not necessarily required.

Spontaneous splenic rupture (SSR) in a patient undergoing hemodialysis has been described as an extremely rare and potentially fatal complication. We report here spontaneous splenic rupture in a 52-year-old woman undergoing regular hemodialysis for end-stage renal disease (ESRD). She complained of colicky abdominal pain in the left upper quadrant area and dizziness when she assumed an upright posture. Her vital signs revealed low blood pressure and tachycardia, which was suggestive of hypovolemic shock. Abdomen CT scan showed splenic hematoma and hemoperitoneum. However, she had no history of any event triggering the splenic rupture. An exploratory laparotomy showed a ruptured spleen and an emergency splenectomy was performed. We suggest that spontaneous spleen rupture may be attributed to uremic coagulopathy and heparin-induced coagulopathy.

We present a case of oral myiasis in a 15-year-old boy with tuberculosis meningitis. The diagnosis was based on the visual presence of wriggling larvae about 1 cm in size and on the microscopic features of the maggots, especially those relating to stigmatic structures. The larvae were identified as third stage larvae of Sarcophaga sp.

Advanced Hodgkin's disease is usually treated with six or more cycles of combination chemotherapy. Spontaneous regression of the cancer is very rarely reported in patients with Hodgkin's disease. We present an unusual case of a patient with Hodgkin's disease who experienced complete remission with a single cycle of chemotherapy, followed by pneumonia. The case was a 36-year-old man diagnosed with stage IVB mixed cellularity Hodgkin's disease in November 2000. After treatment with one cycle of COPP-ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine) chemotherapy without bleomycin, the patient developed interstitial pneumonia and was cared in the intensive care unit (ICU) for two months. Follow-up chest computerized tomography (CT), performed during the course of ICU care, revealed markedly improved mediastinal lymphomatous lesions. Furthermore, follow-up whole body CT and 18-fluorodeoxyglucose positron emission tomography showed complete disappearance of the lymphomatous lesions. Four years later, the patient is well and without relapse. This report is followed by a short review of the literature on spontaneous regression of Hodgkin's disease. To the best of our knowledge, this is the first case report of spontaneous remission of Hodgkin's disease in Korea.

We conducted a meta-analysis using results from the Korean literature to determine whether prostate-specific antigen (PSA) or digital rectal examination (DRE) or transrectal ultrasonography (TRUS) provides a better diagnostic outcome for possible prostate cancer patients. An extensive literature search of MedRIC database et al. (1980 to 2003) was performed using the medical subject headings "PSA", "DRE", "TRUS" and "prostate cancer". Of the 108 articles that we retrieved, 13 studies (2, 029 subjects) were selected for this meta-analysis. The criteria for quality evaluation were as follows: the study subjects must have been compared clinically for suspected prostate cancer, and the articles must have included individual data about sensitivity and specificity for this diagnostic triad based on the biopsy results as a reference standard. For the quantitative meta-analysis process the Hasselblad method was utilized. The pooled sensitivity and specificity for a PSA level greater than 4ng/mL were 91.3% and 35.9%, respectively; and those for a PSA level greater than 10ng/mL were 77.3% and 67.5%, respectively; and those for DRE were 68.4% and 71.5%, respectively; and those for TRUS were 73.6% and 61.3%, respectively. According to the results in a fixed effect model for PSA criteria, the estimates of d for PSA4 and PSA10 were 0.8517 [95% confidence interval (CI) : 0.6694, 1.0340] and 1.0996 (95% CI: 0.9459, 1.2534), respectively. Also, according to the results using a random effect model for both DRE and TRUS criteria, the estimates of d for DRE and TRUS were 0.8398 (95% CI: 0.7169, 0.9627) and 0.8002 (95% CI: 0.6714, 0.9289), respectively. The detection rate for combination testing of PSA, DRE and TRUS for the diagnosis of prostate cancer jumped further to 68.3% or to 76.8%. In conclusion, this study suggests that this diagnostic triad for prostate cancer was noneffective when they were used separately. Therefore, we recommend that the urologists should use PSA together with DRE and TRUS for the primary diagnosis of prostate cancer in men with lower urological symptoms.

MUCP (Maximal urethral closure pressure) is known to be increased in patients with vaginal wall prolapse due to the mechanical obstruction of the urethra. However, urethral function following reduction has not yet been completely elucidated. Predicting postoperative urethral function may provide patients with important, additional information prior to surgery. Thus, this study was performed to evaluate the relationship between MUCP and functional urethral length (FUL) according to stage and age in anterior vaginal wall prolapse patients. 139 patients diagnosed with anterior vaginal wall prolapse at Yonsei University Medical College (YUMC) from March 1999 to May 2003 who had underwent urethral pressure profilometry following reduction were included in this study. The stage of pelvic organ prolapse (POP) was determined according to the dependent portion of the anterior vaginal wall (Aa, Ba). (By International Continence Society's POP Quantification system) Patients were divided into one of four age groups: patients in their 40s (n=13), 50s (n=53), 60s (n=54), and 70 and over (n=16). No difference in MUCP was found between the age groups. The FUL of patients in their 40s was shorter than that of patient's in their 50s and 60s. Patients were also divided into stages: stage II (n=35), stage III (n=76), and stage IV (n=25). No significant difference in MUCP was found according to stage and FUL. However, a significant difference was noted between stage III and IV as stage IV was longer. Anterior vaginal wall prolapse is known to affect urethral function due to prolapse itself, but according to our study, prolapse itself did not alter urethral function. This suggests that, regardless of age and stage, prolapse corrective surgery does not affect the urethral function.

Rifaximin has been reported to be effective for the treatment of hepatic encephalopathy (HE) in Europe. However, it is unknown whether Rifaximin is effective for the treatment of HE in Koreans, therefore we conducted a open-label prospective randomized study to evaluate the efficacy of rifaximin versus lactulose in Korean patients. Fifty-four patients with liver cirrhosis and hepatic encephalopathy were enrolled. Thirty-two patients were randomized to receive rifaximin and 22 to receive lactulose both over a 7-day periods. Before and at the end of treatment, gradation of blood ammonia, flapping tremor, mental status, number connection test (NCT) were performed and estimation of HE indexes determined. Both rifaximin and lactulose were effective in the majority of patients (84.4% and 95.4%, respectively, p=0.315). Blood NH3, flapping tremor, mental status, and NCT was significantly improved by rifaximin and lactulose, and the post- treatment levels of these measures were similar for the rifaximin and lactulose-treated groups, as was the HE index (rifaximin group (10.0-->> 4.2, p=0.000) ; lactulose group (11.3-->> 5.0, p=0.000) ). One patient treated with rifaximin complained of abdominal pain, which was easily controlled. There was no episode of renal function impairment in either treatment group. Rifaximin proved to be as safe and as effective as lactulose for the treatment of Korean patients with hepatic encephalopathy.

The purpose of this volunteer study was to investigate whether pretreatment with UDCA before the administration of 99mTc DISIDA affects the biliary excretion of the DISIDA, and whether it can shorten the total imaging time. Ten young, healthy volunteers (eight males, two females, mean age: 26.3 +/- 2.1 years) participated in the study. Hepatobiliary scintigraphies were performed twice per volunteer within three days, for the control and the UDCA-pretreated studies. In the control study, the gallbladder (GB) was observed first in four cases and the intestine was observed first in another four cases; in contrast, in the UDCA challenge study, the GB was observed first in eight cases. The quantitative results for the factors related to the GB differed significantly between the control and challenge studies. When the subjects were pretreated with UDCA, the time duration until visualization of the GB was shortened, and the maximum activity of the GB became more intense. In conclusion, UDCA pretreatment before hepatobiliary scintigraphy can shorten the total imaging time for evaluating functional obstructions of the cystic duct and increase the specificity of the process.

Bone metastasis is common in lung cancer patient and the diagnosis of bone metastasis is usually made by using imaging techniques, especially bone scintigraphy. However, the diagnostic yield from bone scintigraphy is limited. The aim of this study is to assess the clinical usefulness of urinary pyridinoline cross-linked N-telopeptides of Type I collagen (NTx), urinary deoxypyridinoline (DPD), and serum alkaline phosphatase (ALP) in the assessment of bone metastasis in patients with lung cancer. Urinary NTx, DPD, and serum ALP were measured in 151 lung cancer patients (33 with and 118 without bone metastasis). Lung cancer patients with bone metastasis had a higher urinary excretion of NTx and DPD, and a higher serum ALP than those without bone metastasis. NTx had a better receiver operating characteristic (ROC) curve than DPD and ALP, since the areas under the ROC curve were 0.82, 0.79, and 0.71, respectively. Although correlation coefficients among NTx, DPD and ALP were significantly positive (p < 0.005), the strongest relationship was appeared between NTx and DPD (R=0.616). In conclusion, our results showed the utility of the new bone markers in detecting bone metastasis and suggested that measurement of urinary NTx was valid diagnostic method of bone metastasis from lung cancer.
