This paper reports the study of kaizen as practised in a selection of Japanese companies. After discussing the general understanding of kaizen and proposing a clear definition, the paper describes the methodology of the study, and presents findings from the research, taking Nippon Steel Corporation (NSC) as a base model and comparing this with the data from(More)
The authors report three exceptional cases of vascular lesions occurring during arthroscopic meniscectomies involving the posterior horn of the lateral meniscus. These lesions consisted of false aneurysms of the popliteal artery detected early (1 month) or later (5 months and 3 years) after the procedure, one of which formed a fistula with the accompanying(More)
The turns joining segments of secondary structure have been proposed to be key elements in dictating the folded structures of native proteins. An alternative view assumes that turns play a passive role and are merely default structures that occur as a consequence of interactions between antiparallel segments of secondary structure, with chain reversal being(More)
A case of endocardial tuberculoma of the left atrium in a 20-year-old woman is presented. Ulceration of the tuberculoma at the aortic anulus led to disruption of the aortic valvular attachment and induced severe aortic insufficiency. Replacement of the aortic valve and administration of antituberculous medication permitted an uneventful recovery. This is(More)
34 cases of traumatic rupture of the aortic isthmus have been operated on since 1963: 14 acute ruptures and 20 secondary false aneurysms. Diagnosis was confirmed by aortography. A special feature seen in cases of total transsection is described. Partial extracorporeal bypass was used in 29 cases and direct cross-clamping in 5 cases. Two techniques were(More)
A 21-year-old male patient presented with a typical middle aortic syndrome. Echography disclosed a severe narrowing of the lower thoracic aorta with parietal thickening. The isolated character of the lesion was confirmed by magnetic resonance imaging and aortography. The surgical cure was realized by a Dacron bypass between the upper thoracic descending(More)
The authors report the case of a 72 year old woman with a Carpentier-Edwards bioprosthesis implanted in March 1981 for severe mitral stenosis, asymptomatic until 1986. The progression of effort dyspnoea with prosthetic valve dysfunction despite digitalo-diuretic therapy and severe ventricular subannular pseudoaneurysm. Doppler echocardiography and cardiac(More)
Two hundred patients had an aortic valve replacement with the Smeloff-Cutter prosthesis between 1972 and 1980. One hundred and seventy six patients had aortic valve replacement alone (mortality 2.8%) and 24 patients had additional procedures. The overall mortality was 6.5%. One hundred and eighty seven patients have been followed up for from 4 months to 8(More)
