On 2nd April 2007, at 7:40 local time (20:40 GMT 1 April), a massive earthquake, the epicenter of which was 10 km deep and 45 km south-southeast of Gizo, the provincial capital of the Western Province, struck the Solomon Islands, killing 52 people and displacing approximately 5,000. This study, based on field research in May 2007, reports on the result of the cross-sectional assessment of the bacterial contamination (E. coli, Vibrio spp. and total bacteria) of drinking water and water sources and the longitudinal comparison of dietary intake and epidemiology in six earthquake- and tsunami-affected villages in the Western Province, Solomon Islands. The test-paper method revealed that 92.0% of drinking-water was unsafe in four camps of evacuated people. Only 3 out of 11 drink-water samples collected from safe water sources were free from contamination throughout the study villages. The reported occurrence of diarrhea, while only 7.6 per mil in 2001 and 4.8 per mil in 2003 in one of the study villages, was 12.7 person-days per mil after the disaster in 2007. Deterioration of dietary intakes was not observed. Although further studies are expected to follow up on the changes in water, diet, and health in mid- and long-term recovery operations, the rapid assessment suggested the need to provide safe water or purifiers and education regarding water and hygiene-related management in order to minimize health risks in devastated villages.

Objectives: A survey was conducted to investigate the usability and safety of fentanyl sublingual tablets (FST) and to examine problems associated with their proper use.
Methods: Subjects were 18 cancer inpatients who received FST for breakthrough pain in their pharmacological cancer pain management. Changes in the pain score and the occurrence of adverse effects (nausea, vomiting and somnolence) were compared before and after FST administration.
Results: The pain score before FST administration was 6.4±2.4, and this was significantly improved to 3.4±2.8 at 30 min after administration (p<0.01). Somnolence occurred significantly more often 30 min and 2 h after FST administration than immediately before administration (p<0.05). There were no differences in the occurrence of nausea and vomiting before or after FST administration. Nine patients receiving FST therapy developed xerostomia, but there were no significant changes in the pain score or occurrence of adverse effects while they had xerostomia.
Conclusion: It is essential to observe the oral condition to judge whether FST therapy is indicated, and FST should be administered after providing sufficient oral care. The results indicate the possibility of increased occurrence of somnolence as an adverse effect.

Before the introduction of high density barium for contrast studies of the upper gastrointestinal tract, we conducted a survey concerning the adverse reactions to a swallow of barium and barium concentration.
The incidence of side effects rose as the density of barium increased but the effects were transient. There were no cases requiring medical treatment.
Furthermore, the constipation group and the normal group were examined separately.
The ratio of adverse reactions was high in the constipation group even when the barium density was low. In this group stool hardening and delayed excertion were also noticed.
The constancy of barium stool excretion was basically normal, and the barium density had little effect.
The effects of a laxative on the excretion consistency were investigated. The administration of a laxative did not always have a positive affect on excretion. The timing of the administration of the laxative and the amount of water intake should be examined in the future.
We also investigated how the patients feel when they are swallowing barium. We found that whether feel uncomfortable or not depended on the properties of barium rather than its density.
From these results it appears that appropriate guidance is necessary about the use of high density barium, in order to supress the occurrence of side effects, especially in the constipation group.

Aim:The usefulness of high-density barium, which was made to 150w/v% (MIX150), was examined to obtain better radiographs of the intestines. Methods: “MIX150” was compared with existing pharmaceutical “BAM100” to evaluate x-ray images (barium adhesion, dryness evaluation). MIX150 was used in 232 patients (mean age 56 years), while BAM 100 in 210 patients (mean age 55 years). Results: In terms of adhesion, MIX150 was excellent in the the cecum significantly and in dryness evaluation, in the entire region of the colon. Conclusion: High-density barium (150w/v%) was useful for enhancing the quality of radiographic images.

A case of abdominal aortic aneurysm associated with systemic lupus erythematosus (SLE) is described. SLE is rarely associated with aneurysm of great arteries. Histological investigation revealed marked infiltration of inflammatory cells in the aneurysmal aortic wall. Immunocytochemical analysis using anti-factor VIII-related antigen antibody showed a marked increase of the vasa vasorum with luminal narrowing due to intimal thickning. In this case the major etiology of aortic aneurysm is considered to be non-specific inflammation of the abdominal aorta, not arteriosclerosis.

BACKGROUND/AIMS: It is important to determine the noninvasive parameters of histological features in nonalcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the value of genetic variations as surrogate markers of histological features. METHODS: The parameters that affected the histological features of NAFLD were investigated in 211 Japanese patients with biopsy-proven NAFLD. The relationships between genetic variations in PNPLA3 rs738409 or TM6SF2 rs58542926 and histological features were analyzed. Furthermore, the impact of genetic variations that affected the pathological criteria for the diagnosis of nonalcoholic steatohepatitis (NASH) (Matteoni classification and NAFLD activity score) was evaluated. RESULTS: The fibrosis stage of PNPLA3 GG was significantly more progressive than that of CG by multiple comparisons. Multivariate analysis identified PNPLA3 genotypes as predictors of fibrosis of stage 2 or more, but the impact tended to decrease at stage 3 or greater. There were no significant differences among the histological features of the three genotypes of TM6SF2. PNPLA3 genotypes partly affected the definition of NASH by the NAFLD activity score, but TM6SF2 genotypes did not affect the definition of NASH. CONCLUSIONS: In Japanese patients with biopsy-proven NAFLD, PNPLA3 genotypes may partly affect histological features, including stage of fibrosis, but the TM6SF2 genotype does not affect histological features.

BACKGROUND/AIMS: The aim of this study was to determine the pharmacodynamics of cisplatin following three different treatment procedures for intrahepatic arterial infusion therapy for hepatocellular carcinoma (HCC). METHODS: We divided 13 HCC patients into the following three groups: group A, lone injection of cisplatin (n=3); group B, combined injection of cisplatin and lipiodol, with embolization using small gelatin cubes (GCs) (n=5); and group C, injection of suspended lipiodol with cisplatin powder, with embolization using small GCs (n=5). In each group, the free cisplatin concentration in the hepatic vein was measured at 0, 5, 10, and 30 minutes. RESULTS: The mean free cisplatin concentrations were as follows. For group A, the mean was 48.58 microg/mL at 0 minute, 7.31 microg/mL at 5 minutes, 5.70 microg/mL at 10 minutes, and 7.15 microg/mL at 30 minutes. For the same time points, for group B, the concentrations were 8.66, 4.23, 3.22, and 1.65 microg/mL, respectively, and for group C, the concentrations were 4.81, 2.61, 2.52, and 1.75 microg/mL, respectively. The mean area under the curve (AUC)0-infinity for the free cisplatin concentration was 7.80 in group A, 2.48 in group B, and 2.27 in group C. The AUC0-infinity for the free cisplatin concentration gradually decreased, from group A to group C. CONCLUSIONS: These results indicate that the combination of lipiodol and small GCs may be useful for delaying cisplatin drainage from the liver.

Miriplatin is a novel lipophilic platinum complex that was developed to treat hepatocellular carcinoma (HCC). Although HCC patients frequently have coexisting chronic renal failure, little prospective data are available regarding the clinical toxicity of chemotherapeutic agents used to treat HCC patients with chronic renal failure. In a phase II study, the plasma concentration of total platinum in patients who received miriplatin was very low, and no severe renal toxicity caused by miriplatin injection was reported. Here, we present three cases of HCC with stage 4 chronic renal failure who received transcatheter arterial chemotherapy with miriplatin. All cases were male, ages 72, 84, and 83 years, and had serum creatinine levels of 2.3, 1.6, and 1.9 mg/dL, respectively. Their estimated glomerular filtration rates were 21.9, 20.3, and 22.2 mL/min, respectively. All cases were treated for unresectable HCC with transcatheter arterial chemotherapy with miriplatin. No serious adverse events were observed, and serum creatinine levels did not elevate, even in the patient who experienced renal failure caused by cisplatin administration. These results might suggest that transcatheter arterial chemotherapy with miriplatin can be safely used in HCC patients with chronic renal failure.

For patients with epidermal growth factor receptor (EGFR) mutation-positive lung cancer, the relationship between the dose or duration of treatment with tyrosine kinase inhibitor (TKI) and overall survival remains unclear. Here, we analyzed clinical data of 39 patients who were diagnosed with EGFR mutation-positive non-small cell lung cancer and treated with TKI, but subsequently died. Several parameters were measured in this study: overall survival; first, second, and overall TKI therapy durations; first TKI intensity (actual dose/normal dose); and TKI rate (overall TKI therapy duration/overall survival). The response rate to TKI therapy was 50%, and the median survival was 553 days. After TKI therapy failed, 38.5% patients were re-challenged with TKI. We observed a moderate relationship [r = 0.534, 95% confidential interval (CI) = 0.263 to 0.727, P < 0.001] between overall TKI therapy duration and overall survival. However, we found no relationship between overall survival and first TKI intensity (r = 0.073, 95% CI = -0.380 to 0.247, P = 0.657) or TKI rate (r = 0.0345, 95% CI = -0.284 to 0.346, P = 0.835). Non-small cell lung cancer patients with mutation-positive tumors remained on TKI therapy for, on average, 33% of the overall survival time. These findings suggest that patients with EGFR mutation-positive tumors should not stick to using TKIs.

Introduction:Hyponatremia, which is frequently present in patients with end-stage cancer, causes delirium and disturbance of consciousness and is considered a poor prognostic factor. We report a case of hyponatremia with hypopituitarism in association with leptomeningeal metastasis, resulting in reversible disturbance of consciousness. Case report:A 77 year-old female received chemotherapy at our hospital for postoperative recurrence of lung cancer, and best supportive care due to a side effect. After transfer to another hospital, she experienced a sudden disturbance of consciousness and was returned to our hospital. A detailed examination resulted in a diagnosis of hyponatremia from hypopituitarism following leptomeningeal metastasis involving the cerebral ventricles. Hyponatremia was improved by NaCl supplement and hormone replacement, followed by recovery from disturbance of consciousness. Discussion:QOL of patients with end-stage cancer can be improved through the active treatment of reversible causes of disturbance of consciousness. Conclusion:When severe hyponatremia is detected in cancer patients, it is important to consider the possibility of hypopituitarism with brain metastasis or meninges dissemination in the differential diagnosis.
