AIM: To describe a case in which vitrectomy was required for vitreous hemorrhage and fibrovascular proliferation after laser-induced chorioretinal venous anastomosis (LCVA) for non-ischemic central retinal vein occlusion (CRVO).METHODS: Observational case report.RESULTS: A 72-year-old man complained of central scotoma in the left eye, and was diagnosed as suffering from non-ischemic CRVO. LCVA was performed in another hospital. Although favorable visual function was briefly maintained postoperatively,severe vitreous hemorrhage developed in his left eye, necessitating vitrectomy. CONCLUSION: Considering that LCVA carries a risk of serious complications, we must apply this treatment with caution, especially in ethnic groups, such as the Japanese, in whom pigmentation reacts to photocoagulation excessively.

A 33-year-old woman underwent aortic root replacement for aortic regurgitation and an aneurysm of the ascending aorta due to annuloaortic ectasia. Ehlers-Danlos syndrome was diagnosed by skin biopsy when she was 23 years old. At operation, to avoid mechanical stress to the residual aorta, cardiopulmonary bypass was established via cannulation of the left femoral artery and we used the open distal anastomosis method under hypothermic circulatory arrest with selective cerebral perfusion. Moreover, the sutures of the aortic annulus were reinforced sewing the aortic wall together. Her postoperative course was uneventful. Despite the fragility of the cardiovascular tissues in Ehlers-Danlos syndrome, cardiac surgery could be performed safely with appropriate surgical procedures.

We performed drug susceptibility testing on first- and second-line drugs in Mycobacterium tuberculosis (M. tuberculosis) for the first time in Ghana to obtain preliminary data on drug-resistant tuberculosis. Of 21 isolates (4 new cases and 17 treated cases), 5 (23.8%) were multi-drug resistant tuberculosis (MDR-TB) and 19 (90.5%) were resistant to at least one drug, but no extensively drug-resistant TB (XDR-TB) was identified. Since the target patients were Category II, IV or smear positive at follow-up microscopy, it is understandable that there were many drug-resistant TB cases. Six isolates were resistant to one or two second-line drugs, but the second-line drugs were not approved in Ghana. It is considered that the bacilli were imported from abroad. Preventing the import of drug-resistant TB bacilli is probably one of best ways to control TB in Ghana.

Approximately 100 kinds of Foods for Specified Health Use (FOSHU) are used to “control postprandial elevated blood glucose level”. In this review, we describe their safety and effectiveness.

Hemolytic uremic syndrome (HUS) is a heterogeneous disorder characterized by hemolytic anemia, thrombocytopenia and renal failure that occurs predominantly in infants and young children. However, HUS in adults has also been described as a complication of various chemotherapy regimens with a relatively poor prognosis. Since cisplatin is now widely used for treatment of solid cancers, it is necessary to take into account the possibility of cisplatin-induced hemolytic uremic syndrome as a rare but potentially fatal side- effect. Herein, we describe our experience with a 67-year old woman being treated for a urothelial carcinoma of the bladder who suffered chemotherapy-induced HUS after a cisplatin-based regimen. Plasmapheresis was carried out five times; however, her serum platelets remained depressed, and she subsequently died. We conclude that there is a high risk potential for HUS in patients undergoing intensive chemotherapy for advanced-stage bladder cancer.

An investigation was performed about clinical histories before hospitalization in 1142 cases of gastric cancer during 16 years from 1969 to 1984.
The average term from onset of the disease to hospitalization was 4.53 months which tends to decrease becoming 3.49 months in the latest 5 years. The patients had visited 0.72 other doctor in average before coming to our hospital, 0.35 in early cancer cases and 0.83 in advanced cases. The sources of patients of our surgery were as follows ; 60.5% were introduced from medical department of our hospital, 20.2% were introduced from other clinics or hospitals, 10.6% visited our surgical department directly, and 8.7% came to us after visiting one or some other doctors. The rate of early cancer cases were high and unresectable cases were low relatively in cases from our medical department and direct visitors to our surgical department.
The causative factors of delay of hospitalization more than one month were considered from both sides of patient and doctor. The results were ; no delay 55.3%, delay due to patient's fault 28.2%, delay due to doctor's fault 19.9%. The delay of hospitalization due to either side's fault was one factor of decreasing early cancers and increasing advanced cases. Among those with no delay, however, 22.6% were unresectable cases. Gastric cancers are too malignant to be cured by visiting hospitals with complaints. Gastric mass survey among symptomeless people is the only reasonable way to come out of this difficult situation.

Background: Rapid diagnostic tests (RDTs) are used widely in the diagnosis of malaria. Although the effectiveness of RDTs for malaria has been described in many previous studies, the low performance of RDT particularly for Plasmodium ovale malaria in traveller has rarely been reported. Methods: This was a retrospective cohort study conducted on Japanese travellers diagnosed with malaria at the National Center for Global Health and Medicine between January 2004 and June 2013. The diagnosis of malaria was confirmed by microscopic examination, RDT, and polymerase chain reaction in all patients. The RDTs used in our study were Binax NOW Malaria (Binax Inc., Scarborough, Maine, USA) (BN) and SD Malaria Antigen Pf/Pan (Standard Diagnostics Inc., Korea) (SDMA). We compared the sensitivity of the RDTs to P. ovale malaria and Plasmodium vivax malaria. Results: A total of 153 cases of malaria were observed, 113 of which were found among Japanese travellers. Nine patients with P. ovale malaria and 17 patients with P. vivax malaria undergoing RDTs were evaluated. The overall sensitivity of RDTs for P. ovale malaria and P. vivax malaria was 22.2% and 94.1%, respectively (P < 0.001). The sensitivity of SDMA for P. ovale malaria and P. vivax malaria was 50% and 100%, respectively. The sensitivity of BN for P. vivax malaria was 90.0%, but it was ineffective in detecting the cases of P. ovale malaria. Conclusions: The sensitivity of RDTs was not high enough to diagnose P. ovale malaria in our study. In order not to overlook P. ovale malaria, therefore, microscopic examination is indispensable.

An echocardiogram revealed a mobile mass attached to the left coronary cusp of the aortic valve in an 81-year-old woman. The tumor was surgically removed without valve replacement. The tumor was whitish in color, with a sea anemone-like appearance, and it measured 10 mm in maximum dimension. It was histopathologically defined as papillary fibroelastoma (PFE), and the postoperative course was uneventful. Primary cardiac tumors are rare, and the majority are myxomas. However recent advances in noninvasive examination and surgery may increase the detection of PFE, which occurs most frequently on the endocardial surface of the cardiac valve. We report a case of cardiac PFE with a review of the pertinent literature.

Results: A total of 153 cases of malaria were observed, of which 113 patients were Japanese travellers. Nine patients with P. ovale malaria and 17 patients with P. vivax malaria performing RDTs were evaluated. The overall sensitivity of RDTs for P. ovale malaria was 22.2% and that for P. vivax malaria was 94.1% (P < 0.001). The sensitivity of SDMA for P. vivax malaria was 100% and that for P. ovale malaria was 50%. The sensitivity of BN for P. vivax malaria was 90.0%; however, it was unable to detect the cases of P. ovale malaria. Conclusions: The sensitivity of RDTs was not high enough to diagnose P. ovale malaria in our study. Thus, microscopic examination is indispensable not to overlook P. ovale malaria.

Medical therapies, adapted to local requirements, are necessary in the field of community medicine. Generalized medical treatment is often all there is in Japan's Konsen Area, due to the large number of elderly people and a paucity of medical institutions. Kampo medical treatment is useful for elderly patients with plural diseases, and the demand for such treatment has been increasing. Therefore, we collected data on Kampo prescriptions prescribed by the doctors at the Nakashibetsu Municipal Hospital, which is the main local hospital in the Konsen Area, from 2010 to 2013. We conducted similar investigations at the Kushiro Red Cross Hospital in Kushiro city, which is centrally located in the Konsen Area, and at Asahikawa Medical University Hospital in Asahikawa, central Hokkaido. The aim of these investigations was to compare Kampo medicine use based on hospital location and size. The results can be used in community medicine to enhance the use of Kampo medicine with increase for its demand. Medical students and doctors should be educated in Kampo medicines, since their prescriptions have a significant impact on community health.
