A 51-year-old man underwent partial hepatectomy in July 2000 for metastatic liver tumor after gastrectomy for gastric cancer. He received seven cycles of hepatic arterial infusion with mitomycin C 20 mg during induced hypertension with angiotensin II from October 2000 to April 2001. His body temperature sometimes rose above 38 degrees C in June and jaundice appeared in August 2001. Blood biochemistry tests showed an elevated value of alkaline phosphatase, gamma-glutamyl transpepsidase and total bilirubin. Based on an enhanced CT scan of the liver showing a low-density area along intrahepatic biliary tracts and hepatic arteriography showing stenosis of the proper hepatic artery, we diagnosed bile duct necrosis and hepatic necrosis. Bile duct necrosis is a serious complication in arterial infusion chemotherapy, and the infusion chemotherapy should be suspended or the dose should be reduced for patients with abnormalities shown by hepato-biliary function tests.

International studies in geographic pathology provide background information that a disease may have a quite different incidence and resulting mortality as a function of area of residence. Investigations in animals can model fairly precisely what is learned through such international research, and provide the basis for examining relevant hypotheses and, more importantly, possible mechanisms of action. These approaches can yield public health recommendations and health promotion activities. Regular intake of foods rich in saturated fats, such as meat and certain dairy products, raises the risk of coronary heart disease, especially in smokers. The total mixed fat intake is associated with a higher incidence of the nutritionally linked cancers (i.e. of the postmenopausal breast, distal colon, prostate, pancreas, ovary and endometrium). Monounsaturated oils, such as olive or canola oil, are low-risk fats, as shown in animal models, and through the finding that the incidence of coronary heart and neoplastic diseases is lower in the Mediterranean region, where such oils are customarily used. Fish and fish oils are protective. The associated genotoxic carcinogens for several of these cancers, and also in heart disease causation, are heterocyclic amines, produced during the broiling and frying of creatinine-containing foods such as meats. Excessive salt intake is associated with high blood pressure and with stomach cancer, especially with inadequate intake of potassium, from fruits and vegetables, and calcium from certain vegetables and low-fat dairy products. Bran cereal fiber intake, especially with adequate calcium, yields an increased stool bulk, eliminating factors involved in colon and breast cancer. Vegetables and fruits, as well as soy products, are rich in antioxidants that are essential to lower disease risk stemming from reactive oxygen species in the body. Green and black tea are excellent sources of such beneficial antioxidants of a polyphenol nature, as are cocoa and chocolates. Antioxidants also extend healthy aging and may protect against Alzheimer's and Parkinson's diseases. Nutritional lifestyles can be described for most populations in the world and offer the possibility of a healthy long life.

A 58-year-old normotensive male with normal renal function and gastric cancer underwent total gastrectomy and received adjuvant chemotherapy with mitomycin C (MMC) for 10 months. He developed anemia, hypertension, and renal function impairment 9 months after initiation of chemotherapy. Kidney biopsy showed thrombotic microangiopathy with marked mesangiolysis and expansion of the subendothelial space resulting in cystic dilation of the glomerular capillaries, and cellular atypia in the tubular cells. His renal function deteriorated gradually then stabilized after treatment with plasma exchange, antihypertensive agents, and antiplatelet agents. He had no sign of tumor recurrence after 3 years of follow-up. We suggest that patients receiving MMC should have their blood pressure and renal function closely monitored for the possibility of development of drug-induced renal insufficiency.

A genome-wide linkage equilibrium mapping is an emerging strategy to identify risk-modifying genes for common diseases, despite unsettled controversies upon many aspects, including its premises, designs, marker choices and cost benefits. One large-scale attempt in Japan aims to identify disease-associated single nucleotide polymorphisms (SNPs) for five diseases among the Japanese population: Alzheimer's disease, gastric cancer, diabetes, hypertension and asthma. Following an initial screening of c.a. 100,000 SNPs on 940 subjects (five diseases x 188 patients) to select about 2,000 SNPs, we compared which subsequent screening design is more appropriate, and an additional one or two screens to further narrow down any disease-associated SNPs within a fixed total volume of 15,040,000 typings (2,000 SNPs x five diseases x 1,504 subjects, comprising 752 cases and 752 controls). We employed a Monte Carlo simulation to evaluate the probability of identifying truly disease-associated SNPs. The results suggest the single additional stage design (i.e., total two-stage design including the initial screening of 100,000 SNPs) was more practicable for the simple reason that the gain in probability is considered insufficient relative to an associated increase in study complexity in the three-stage design.

Many Koreans were forced to move to Japan while Korea was occupied by Japan. Consequently, when the atomic bombs were dropped on Hiroshima and Nagasaki an estimated 40,000 Koreans died and 30,000 survived. In 2004, 2,235 Koreans were registered as A-bomb survivors in South Korea. A mail questionnaire survey to evaluate the present status and self-reported diseases of the Korean survivors was conducted. In total, 1,256 questionnaires were returned and analysed. The most frequent chronic diseases reported by Korean survivors were hypertension (40.1 per cent), peptic ulcer disease (25.7 per cent), anaemia (23.3 per cent) and cataracts (23.1 per cent). The most frequent malignant diseases were stomach cancer (1.9 per cent), colon cancer (0.5 per cent) and leukaemia/multiple myeloma (0.4 per cent). This study suggests that further investigations are needed into the health concerns of the survivors and into health protection measures.

A 66-year-old man with hypertension and hyperlipidemia developed a hemorrhagic stomal ulcer and massive hematoma of the face at 4 and 7 months, respectively, after fundusectomy for early gastric cancer. The diagnosis of acquired hemophilia A was made based on the marked prolongation of activated partial thromboplastin time, an extremely low factor VIII activity, and a very high-titer factor VIII inhibitor. After admission, oral prednisolone and cyclophosphamide were started. In addition, activated prothrombin complex concentrates and recombinant activated factor VII were intravenously administered which successfully controlled his hemorrhage. Only 1 week after the episode of bleeding, however, he complained of abdominal pain accompanied by watery stool with fresh blood. The diagnosis of ischemic colitis was made based on the clinical course and the findings on both CT-scan and colon fiberoscopy. The colitis spontaneously and quickly resolved with conservative observation. To the best of our knowledge, this is the first reported case of ischemic colitis that occurred in an acquired hemophilia patient without simultaneous administration of coagulation factors or antifibrinolytic agents. We should thus pay attention to the possible occurrence of thrombotic events even in acquired hemophilia patients in the presence of risk factors for thrombosis.

We report a case of early gastric cancer and early colon cancer detected by positron emission tomography (PET) cancer screening. A 64-year-old male patient with an unremarkable past history except for hypertension and cerebrovascular disease underwent 18F-FDG PET for cancer screening. Images revealed increased uptake in the gastric antrum and sigmoid colon. Both areas appeared suspicious for neoplasm on subsequent fluoroscopy and endoscopy, and biopsies were positive for neoplasia at both sites. The gastric lesion was treated by distal gastrectomy and D2 lymphadenectomy and the colon cancer by endoscopic mucosal resection (EMR). Both surgical specimens were positive for cancer.

A 70-year-old man presented with dizziness, headache and hearing loss. He was admitted to our hospital because of increasing unsteadiness of gait. Magnetic resonance imaging of the brain revealed meningeal thickening with enhancement. The lumbar puncture revealed high opening pressure. The cerebrospinal fluid showed pleocytosis, high carcinoembryonic antigen (CEA) concentration, and presence of neoplastic cells, leading to the diagnosis of leptomeningeal carcinomatosis. Systemic investigation for primary neoplasm identified a Bormman type 3 gastric cancer (papillary adenocarcinoma with micropapillary pattern). Except for the meninges, no metastatic lesions could be detected. A ventriculoperitoneal shunt (Codman Hakim Programmable Valve) was placed for management of intracranial hypertension and intrathecal chemotheray. He was started on oral S-1 (TS-1) combined with intrathecal methotrexate injection using the VP shunt reservoir. In two weeks, headache and hearing loss completely disappeared and gait disturbances started to improve. CSF findings also improved remarkably with disappearance of neoplastic cells and almost normalization of CEA. For the next five months, he was well on oral S-1 and monthly intrathecal chemotherapy, being able to walk using a walker and to stay at home. He subsequently developed posterior cortical symptoms such as prosopagnosia and cortical blindness and gradually lapsed into coma. He died from pneumonia one year after the onset of neurological symptoms. At autopsy, primary gastric cancer was found but much reduced in size. No peritoneal metastasis could be found. In the brain, leptomeningeal carcinomatosis involved the occipital lobes, the base of the temporal lobe, and the cerebellum. We suggest that intrathecal chemotherapy using ventriculoperitoneal shunt with programmable valve system could be an effective method for the treatment of meningeal carcinomatosis.

Gastric cancer was detected in a 71-year-old man with severe aortic stenosis. According to ACC/AHA guidelines, aortic stenosis in the patient was so severe that noncardiac surgery was considered appropriate only after aortic valve replacement. However, due to uncontrollable hemorrhage from gastric cancer, total gastrectomy was urgently required. Surgery was performed under epidural and general anesthesia. Blood pressure and heart rate were stable during anesthetic induction, tracheal intubation and skin incision. Just after peritoneal incision, however, ST decreased significantly following hypertension and sinus tachycardia, which were controllable by deepening of the anesthetic level. This ST depression was dependent on heart rate but not blood pressure. Therefore, in order to control the heart rate and prevent myocardial ischemia, low dose landiolol was infused prophylactically. This agent regulated the heart rate below 85 beats per minute without inducing hypotension and prevented myocardial ischemia during the remaining anesthetic course including extubation and recovery from anesthesia. Although beta blocker is not generally recommended in patients with aortic stenosis, present case suggests that landiolol is effective and useful to prevent cardiac ischemia even in a patient with severe aortic stenosis.

We have experienced a successful case of liver metastasis from gastric cancer treated with S-1 plus induced hypertensive hepatic arterial infusion chemotherapy. A 50-year-old man had undergone distal gastrectomy with extended lymphadenectomy for advanced gastric cancer. Although he was given 100 mg/day of S-1 for postoperative adjuvant therapy, an abdominal CT scan showed a liver metastasis at the hepatic segment 6 after 3 courses of adjuvant chemotherapy. Then, intra-arterial hepatic cannulation connecting to a subcutaneously implanted port system was indwelt via left subclavial artery. Mitomycin C (10 mg) was injected through out the induced hypertension with intravenously-administered angiotensin II once a month. After he received three courses of this combination chemotherapy, the liver metastasis has disappeared on CT scan and a complete response (CR) has been maintained.
