BACKGROUND: Administration of anticancer drugs may damage gastrointestinal epithelium, thereby increasing the permeability of the gastrointestinal mucosa. It is known that intestinal permeability test using 51Cr-EDTA is a useful test to assess the damage of intestine. The aim of this study was to evaluate intestinal permeability in patients who were treated with 5-fluorouracil (5-FU) based chemotherapy and to evaluate the relationship between the excretion of 51Cr-EDTA and the grading of mucositis. METHODS: Twenty eight patients who were treated with 5-FU based chemotherapy were chosen as study cases while 18 healthy volunteers as controls. Intestinal permeability was assessed by measurement of the urinary excretion of 51Cr-EDTA after oral challenge, and the National Cancer Institute common toxicity criteria were used for assessing oral mucositis. RESULTS: All except 3 patients in the chemotherapy group experienced grade 1~3 stomatitis. The median value of intestinal permeability test was significantly higher in the chemotherapy group than in control group (7.61%, range 2.10-22.92 vs 2.17%, range 1.16-2.76, respectively, p<0.001). The grading of oral mucositis did correlate with the urinary excretion of 51Cr-EDTA (p<0.001, r=0.867). CONCLUSIONS: The measurement of 51Cr-EDTA excretion after oral challenge may be a useful test for evaluating the intestinal permeability by chemotherapy induced intestinal mucosal damage. Testing of intestinal permeability using 51Cr-EDTA may be applicable to evaluate the effect of therapeutic trials in patients with chemotherapy induced mucositis.

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder of the primitive hematopoietic stem cells. CML is characterized by the overproduction of myeloid cells, which results in marked splenomegaly and leukocytosis. CML presented by multiple chloromas is extremely rare. Multiple chloromas in the skin and brain are quite rare as the initial presentation of CML. These rare manifestation should alert clinicians to include CML in the differential diagnosis of patients presenting with multiple non-pruritic skin nodules or neurologic symptoms. Dasatinib has promising therapeutic potential for managing intracranial leukemic disease. Here, we report the case of a patient who visited the hospital with multiple chloroma which is unusual presentation of CML, and treated with dasatinib successfully.

Hepatic tuberculosis (TB) is usually associated with pulmonary or miliary TB, but primary hepatic TB is rare less than 1% of all cases of TB. Because hepatic TB lacks typical clinical manifestations as well as typical imaging findings, it is difficult to differentiate TB from the malignancies such as hepatic metastasis, intrahepatic cholangiocarcinoma and hepatocellular carcinoma. A 76-year-old woman was presented with single liver mass detected on routine examination. She was clinically diagnosed with hepatocellular carcinoma and underwent surgical excision of the lesion. However, histologic examination revealed caseous necrotizing granuloma and the PCR test for Myco-bacterium tuberculosis was positive. The final diagnosis was primary hepatic TB. Here we report the case with primary hepatic TB who was initially misdiagnosed with hepatocellular carcinoma and underwent surgical excision.

Systematic and effective welfare for the disabled is possible when there are scientific and objective criteria demonstrating either presence or severity of the impairment. We need our own scientific criteria suitable for our culture and society, since the impairment is influenced by them. In 2007, we established the Developing Committee of Korean Academy of Medical Sciences (KAMS) Guideline for Impairment Rating under KAMS supervision. We included all fixed and permanent physical impairments after a sufficient medical treatment. The impairment should be stable and medically measurable. If not, it should be reevaluated later. We benchmarked the American Medical Association Guides. The KAMS Guideline should be scientific, objective, valid, reasonable and practical. In particular, we tried to secure objectivity. We developed the KAMS Guideline for Impairment Rating.

BACKGROUND: Aldosterone antagonists are reported to have beneficial effects on diabetic nephropathy by effective blocking of the renin-angiotensin-aldosterone system. We investigated the renoprotective effect of the selective aldosterone receptor blocker eplerenone, the angiotensin converting enzyme inhibitor lisinopril, and combined eplerenone and lisinopril treatment in type 2 diabetic rats. METHODS: Animals were divided into six groups as follows: Otsuka Long-Evans Tokushima Fatty (OLETF) rat control, OLETF rats treated with a low dose of eplerenone (50 mg/kg/day), OLETF rats treated with a high dose of eplerenone (200 mg/kg/day), OLETF rats treated with lisinopril (10 mg/kg/day), OLETF rats treated with a combination of both drugs (eplerenone 200 mg/kg/day and lisinopril 10 mg/kg/day), and obese non-diabetic Long-Evans Tokushima Otsuka rats for 26 weeks. RESULTS: Urinary albumin excretion was significantly lower in the lisinopril group, but not in the eplerenone group. Urinary albumin excretion was decreased in the combination group than in the lisinopril group. Glomerulosclerosis and renal expression of type I and type IV collagen, plasminogen activator inhibitor-1, transforming growth factor-beta1, connective tissue growth factor, and fibronectin mRNA were markedly decreased in the lisinopril, eplerenone, and combination groups. CONCLUSION: Eplerenone and lisinopril combination showed additional benefits on type 2 diabetic nephropathy compared to monotherapy of each drug.

BACKGROUND/AIMS: Treating hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) remains controversial. We compared the outcomes of hepatic resection (HR), transarterial chemoembolization (TACE), and sorafenib therapy as treatments for HCC with PVTT. METHODS: Patients diagnosed as HCC with PVTT between January 2000 and December 2011 who received treatment with sorafenib, HR, or TACE were included. Patients with main PVTT, superior mesenteric vein tumor thrombosis, or Child-Turcotte-Pugh (CTP) class C were excluded. The records of 172 patients were analyzed retrospectively. HR, TACE, and sorafenib treatment were performed is 40, 80, and 52 patients respectively. PVTT was classified as either involving the segmental branch (type I) or extending to involve the right or left portal vein (type II). RESULTS: The median survival time was significantly longer in the HR group (19.9 months) than in the TACE and sorafenib groups (6.6 and 6.2 months, respectively; both p<0.001), and did not differ significantly between the latter two groups (p=0.698). Among patients with CTP class A, type I PVTT or unilobar-involved HCC, the median survival time was longer in the HR group than in the TACE and sorafenib groups (p=0.006). In univariate analyses, the initial treatment method, tumor size, PVTT type, involved lobe, CTP class, and presence of cirrhosis or ascites were correlated with overall survival. The significant prognostic factors for overall survival in Cox proportional-hazards regression analysis were initial treatment method (HR vs. TACE: hazard ratio=1.750, p=0.036; HR vs. sorafenib: hazard ratio=2.262, p=0.006), involved lobe (hazard ratio=1.705, p=0.008), PVTT type (hazard ratio=1.617, p=0.013), and CTP class (hazard ratio=1.712, p=0.012). CONCLUSIONS: Compared with TACE or sorafenib, HR may prolong the survival of patients with HCC in cases of CTP class A, type I PVTT or unilobar-involved HCC.

BACKGROUND: Antitumor drugs such as 5-fluorouracil (5-FU) are known to induce intestinal damages and bacterial translocation. The present studies examined whether or not bovine colostrum protects against gut barrier damage, bacterial translocation and endotoxemia from these antitumor drugs. METHODS: Rat received either no drug, chemotherapy alone (5-FU, 300 mg/kg intraperitoneal injection) or bovine colostrum (4 g/day per os) for 5 days prior to 5-FU and for 5 days afterward. Intestinal permeability, enteric aerobic bacterial counts, serum albumin and protein levels, and pathologic findings of ileum were measured. Bacterial translocation to systemic blood, mesenteric lymph nodes, liver and spleen were measured. Systemic plasma endotoxin levels were quantified by the chromogenic limulus amebocyte lysate (LAL) technique. RESULTS: 5-FU increase intestinal permeability and plasma endotoxin levels, and decreased serum levels of total protein and albumin. Also 5-FU induced bacterial translocation to mesenteric lymph nodes, liver and spleen, not to systemic blood, but did not induce changes of enteric bacterial numbers and mucosal damages of small intestine. Combined administration of bovine colostrum with 5-FU reduced an increase in intestinal permeability and declines in serum albumin and protein levels by 5-FU. Bovine colostrum supplements also reduced bacterial translocation to mesenteric lymph nodes, liver and spleen, and endotoxemia. CONCLUSION: Bovine colostrums may beneficial effects in preventing 5-FU induced gut barrier damage, bacterial translocation and intestinal endotoxemia.
