Mass Gastric Examinations of Prisoners at Miyagi Prison in Japan

Mass examinations of the stomach were carried out on 79 convicts over 40 years of age confined in the Miyagi Prison, Japan. Of the 79 subjects, 11.9% were found to need detailed examination of the stomach which disclosed gastric polyp in one case and scar from gastric ulceration in one. None was found to have carcinoma of the stomach. Complaints of symptoms were obviously more frequent with the convicts as compared with a control group. There was not, however, a significant depression in efficiency of this group examination by photofluorography, as compared with the usual gastric mass examination on general inhabitants.     

Health promotion in Japan: An overview

Health promotion in Japan today should be seen in the contextof its historical development. The movement started as hygieniceducation in the 1950s; in the 1960s health education appeared,in the early 1970s health promotion was launched as a publicpolicy and in 1978 the government introduced health creationpolicy which was an extension of the previous health promotionpolicy. This development was closely linked with the rapid changein the morbidity and mortality structure, the ageing populationstructure and the rapid expansion of medical costs during thisperiod. Owing to this historical development, the concept of healthpromotion in Japan is wider than is usual in Europe and theNorth America. In Japan it includes health checks, family counselling,a fitness movement, community development, etc. Health promotionin Japan is closely associated with medical care and healthchecks. By law at least 5% of health insurance expenditure onthe compulsory health insurance schemes should be used for preventiveactivities in which health promotion plays an important role.A large amount of resources was used and experience accumulatedin health promotion. Despite the flourishing health promotion activities both onthe governmental and non-governmental levels in recent years,a comprehensive national health promotion does not yet exist.As in many countries collaboration and coordination among thegovernmental bodies, government and NGOs, and among NGOs isfar from satisfactory. It is badly needed.     

Efficacy of Superficial Temporal Artery-Middle Cerebral Artery Double Anastomoses in a Patient with Rapidly Progressive Moyamoya Disease: Case Report

Moyamoya disease can be associated with a rapidly progressive course in young patients. This report describes a patient with moyamoya disease who experienced rapid disease progression, resulting in cerebral infarction and a wide area of diminished cerebral perfusion. Double superficial temporal artery (STA)-middle cerebral artery (MCA) anastomoses were utilized to immediately increase cerebral perfusion in the affected area. This case involved a 5-year-old girl who had been diagnosed with moyamoya disease and had undergone STA-MCA anastomosis with indirect bypass in the right hemisphere at the age of 3. At the time of presentation, magnetic resonance (MR) imaging showed cerebral infarction at the left frontal lobe, and MR angiography showed rapidly progressive narrowing of the left MCA that had not been present 3 months prior. N-isopropyl-p-[I123] iodoamphetamine single-photon emission computed tomography (IMP-SPECT) showed markedly decreased uptake in the left hemisphere. She underwent emergent STA-MCA double anastomoses with indirect bypass on the left side. IMP-SPECT showed marked increase in uptake in the left hemisphere. The anterior cerebral artery (ACA) territory adjacent to the cerebral infarction also showed increased uptake on the SPECT. Postoperatively, there were no clinical or radiographic indications of ischemic or hemorrhagic complications. Double anastomoses are effective in quickly and significantly increasing blood flow. The postoperative course in this case was uneventful. Double anastomoses are a surgical option for patients with moyamoya disease who show rapid disease progression, even in those in the acute phase of cerebral infarction.     

An early gallstone clearance following repeat piezoelectric lithotripsy

Piezoelectric extracorporeal litotripsy was performed in 128 symptomatic patients with radiolucent gall-bladder stones to assess the significance of disintegration in fragment clearance. Up to 10 repeat lithotripsy sessions were scheduled to achieve a fragment target size of <3 mm. Fragmentation assessed by the size of the largest fragments after the last session was graded into three classes. I: sludge-like disintegration, 18%; II: <3 mm (mean ± s.d., 1.7 ± 0.5 mm), 56%; and III: < 3 mm (3.3 ± 0.6), 26%. All patients were initially subjected to lithotripsy alone. Bile acid dissolution therapy was started only when ultrasonography failed to show the evidence of decrease in the <3 mm fragments during a 1 month follow up. Finally, 69 patients (54%) were treated by lithotripsy alone, and the remaining 59 received additional dissolution therapy at a mean period of 2.5 months after the initial lithotripsy. The rate of complete clearance in class I, II and III patients was 91, 42 and 10% at 6 months and 100, 68 and 49% at 18 months, respectively. Significant differences were noted between the three fragmentation grades (I vs II, III, P <0.0001; II vs III, P <0.02). The patients with complete clearance within 6 months were seen only in those treated by lithotripsy alone, while the majority (87%) of patients with complete clearance during the later period were seen in those treated by additional dissolution therapy. We conclude that a high degree of fragmentation appears to lead stones to an earlier period clearance, and reduce the need for dissolution therapy.     

Hepatic angiomyolipoma pre-operatively diagnosed by imaging

An asymptomatic patient with pre-operatively diagnosed solitary angiomyolipoma is reported. The tumour was a well defined, fat density mass on computerized tomography (CT) and magnetic resonance imaging (MRI), and a hyperechoic nodule with a sharp margin on ultrasonography (US). The lesion was hypervascular on arteriography and CT during hepatic angiography. Chemical shift MRI confirmed the fat component within the lesion. Although a review of the literature shows this tumour to be rare and difficult to differentiate from a malignant lesion pre-operatively, the pre-operative diagnosis of angiomyolipoma is considered feasible when the characteristic findings as described here are present.     

Sonographic patterns of radiolucent gall-bladder stones for predicting successful shock-wave lithotripsy

The aim of this study was to examine whether the sonographic patterns of gallstones are useful for predicting the outcome of piezoelectric shock-wave lithotripsy. Pretreatment analysis of gallstones based on our sonographic classification was conducted on 115 patients with radiolucent solitary stones of 10–30 mm in diameter, monitored for at least a year after the first lithotripsy. All stones were categorized as type I with gradual attenuation of echoes: type Ia, the stone echo appears as a full moon, usually accompanied by comet-tail artifacts beyond the stone itself (n= 55); type Ib, the stone echo showing the anterior half of the stone, seen as a half moon (n= 29); and type Ic, the stone echo seen as a crescent (n= 31). The most complete fragmentation, ‘pulverization', was achieved at a significantly higher rate for type Ia (51%) than for type Ib (14%, P < 0.005) and type Ic (7%, P < 0.0001) after significantly fewer shock-waves (vs type Ib, P < 0.01; vs type Ic, P < 0.0001). The rate of complete clearance at 12 months after lithotripsy was significantly greater for type Ia (91%) than for type Ib (62%, P < 0.01) and type Ic (45%, P < 0.0001). Comparison of the sonographic and computed tomography (CT) patterns of stones revealed a close relationship between the two: the vast majority (98%) of type Ia showed the iso- or hypo-dense, and the majority (90%) of type Ic the rimmed. We conclude that the sonographic patterns of radiolucent gallstones appear to provide another parameter for predicting fragmentation and clearance of the stones in lithotripsy treatment, and to be probably alternative to pretreatment CT.     

Trazodone for aggression in an adolescent with hydrocephalus

Abstract A case of 19 year old male with hydrocephalus is reported whose aggressive self-injurious behaviors were resistant to conventional pharmacotherapy but successfully treated by trazodone. In addition to the self-injurious behaviors, this patient displayed withdrawal and eating refusal, which initially resulted in his admission to a psychiatric ward. Various conventional treatments with pharmacotherapy (e.g., tricyclic antidepressants, antipsychotics, anxiolytics and anticonvulsants) in combination with psychotherapy and family therapy proved not to be effective for 15 months. Neither was electroconvulsive therapy successful. Administration of trazodone for 5 months after tapering of the above agents improved his aggressive behaviors. A survey of previous cases with organic brain syndromes who had aggressive behaviors and responded well to trazodone revealed that most of the cases were aged individuals and that cases in adolescence are rare.
