We report a case of patient who is alive 10 years after total gastrectomy and partial liver resection for gastric cancer and liver metastasis, respectively. The patient is 69-year-old man who was examined in another hospital for nausea, tarry stool, and weight loss. Diagnosis by stomach fluoroscopy revealed gastric cancer and he was admitted to our hospital in September 2002. Computed tomography (CT) scan and ultrasonography (US) revealed liver metastasis in S7. Distant metastases were not detected. The patient underwent distal gastrectomy, transverse colon partial resection, and a hepatic partial resection in October 2002. Pathological findings showed SI, N1, and M1. Though adjuvant chemotherapy was given, a local recurrence was detected in the liver in February 2003. Hepatic arterial infusion (HAI) was started in April 2003. After 8 courses, HAI was discontinued because of hepatic artery obstruction. No additional distant metastases were found. Therefore, transdiaphragmatic radiofrequency ablation (RFA) was performed by thoracotomy. Currently, the patient is treatment free and remains alive after 10 years with no recurrence.

A 43-year-old diabetic man had a productive cough and high fever and was admitted to another hospital. His condition did not improve despite treatment with Cefepime, and he was transferred to our hospital. Chest X-ray films and CT findings showed pulmonary infiltration and diffuse ground-glass opacities in bilateral lung fields, but disseminated nodules were not identified. Since his bronchial lavage fluid (BALF) was bloody, we suspected diffuse alveolar hemorrhage due to vasculitis. Steroid pulse therapy was given, and his fever and chest X-ray findings completely improved. However, 1 week later, he again suffered a high fever and bloody sputum, and a chest X-ray film showed granular shadows in bilateral lung fields. He died of respiratory failure on the 18th hospital day despite treatment and mechanical ventilation. An autopsy revealed many necrotizing epithelioid granulomas in both lungs, the liver, the spleen, both kidneys and both adrenal glands. These findings indicated miliary tuberculosis, and a culture of his sputum and BALF finally revealed mycobacterium tuberculosis. Marked alveolar hemorrhage and a hyaline membrane were also found in both lungs, but vasculitis was not recognized in any organ. We report this case, because to the best of our knowledge diffuse alveolar hemorrhage has not been reported as the primary symptom of miliary tuberculosis.

Unusual to-and-fro waveforms were demonstrated in the left gastric vein on Doppler sonograms in four patients with liver cirrhosis. The patterns of the to-and-fro waveforms were diverse in each of the patients: both hepatopetal and hepatofugal flow occurred in a single waveform in case 1, changes in the flow direction with flow interruption were noted in case 2, and changes in flow direction without observation of flow interruption and changes after meals were noted in cases 3 and 4, respectively. These waveforms may represent a transitional phase during the development of a portal systemic shunt in patients with portal hypertension. © 2011 The Japan Society of Ultrasonics in Medicine.

Objectives: Recently several clinical isolates of Streptococcus agalactiae [also known as group B Streptococcus (GBS)] that have acquired reduced penicillin susceptibility (PRGBS) by amino acid substitutions in the penicillin-binding protein 2X have emerged. The frequency of fluoroquinolone (FQ)- and macrolide-resistant streptococci among PRGBS is not yet known. Methods: Fifty-seven GBS [19 PRGBS and 38 penicillin-susceptible GBS (PSGBS)], isolated from different medical institutions in Japan, were studied. For GBS, the MICs of penicillin G, levofloxacin and erythromycin were determined using the agar dilution method. Nineteen PRGBS were previously confirmed as genetically diverse streptococci by PFGE. Further, the mechanisms underlying penicillin, FQ and macrolide non-susceptibility/resistance were analysed. Results: The frequency of non-susceptibility to FQs among PSGBS was 18.4% (7/38), whereas that among PRGBS was 100% (19/19). The frequency of resistance to erythromycin among PSGBS was 7.9% (3/38), while that among PRGBS was 47.4% (9/19). Statistical significance was determined using Fisher's exact test between reduced penicillin susceptibility and FQ non-susceptibility (P ≤ 0.0001) and macrolide resistance (P = 0.0012). The resistance/non-susceptibility mechanisms among PRGBS were diverse, suggesting that the PRGBS examined were not clonal. Conclusions: PRGBS isolates tend to show resistance to FQs and/or macrolides. Because the drug choice for treating these multidrug-resistant GBS is more limited than that for usual GBS, these strains may present future public health challenges. © The Author 2012.

Background: According to the Japanese Circulation Society guidelines, a bioprosthesis is recommended for aortic valve replacement (AVR) in patients aged ≥65 years who have no risk factors for thromboembolism. There are few data, however, regarding the actual durability of bioprosthetic valves in Japanese patients. The purpose of this study was to assess the long-term durability of Carpentier-Edwards pericardial (CEP) valves in Japanese AVR patients, and to assess the risk factors for reoperation due to structural valve deterioration (SVD). Methods and Results: From 1986 to 2001, a total of 591 patients underwent AVR with CEP valves in 9 hospitals. Of these, 574 patients (mean age, 71.9±8.5 years) were analyzed in this study. There were 26 in-hospital deaths (4.5%). The 10-year follow-up rate was 82.6% and the median follow-up time was 9.2 years. Freedom from reopera-tion due to SVD was 99.5%, 96.7%, and 87.5% at 5, 10, and 15 years, respectively. Factors that raised the risk of reoperation due to SVD included younger age at operation and history of prior operation. In patients aged ≥65 years, freedom from reoperation due to SVD was 94.4% at 15 years. Conclusions: The durability of CEP valves in patients with AVR was excellent, especially in elderly patients. Thus, it seems appropriate to follow the current Japanese Circulation Society recommendations for the use of biopros-thetic valves.
