Background
Reports on childhood cancer survivors estimated cumulative probability of developing secondary neoplasms vary from 3,3% to 25% at 25 years from diagnosis, and the risk of developing another cancer to several times greater than in the general population. 相似文献12.

Computerized information systems, especially decision support systems, have become an increasingly important role in medical applications, particularly in those where important decision must be made effectively and reliably. But the possibility of using computers in medical decision making is limited by many difficulties, including the complexity of conventional computer languages, methodologies and tools. Thus a conceptual simple decision making model with the possibility of automating learning should be used. In this paper we introduce a cardiological knowledge-based system based on the decision tree approach supporting the mitral valve prolapse determination. Prolapse is defined as the displacement of a bodily part from its normal position. The term mitral valve prolaps (PMV), therefore, implies that the mitral leaflets are displaced relative to some structure, generally taken to be the mitral annulus. The implications of the PMV are the following: disturbed normal laminar blood flow, turbulence of the blood flow, injury of the chordae tendinae, the possibility of thrombus's composition, bacterial endocarditis, and finally hemodynamic changes defined as mitral insufficiency and mitral regurgitation. Uncertainty persists about how it should be diagnosed and about its clinical importance. It is our deep belief that the echocardiography enables properly trained experts armed with proper criteria to evaluate PMV almost 100%. But unfortunately, there are some problems concerned with the use of echocardiography. In that manner we have decided to start a research project aimed at finding new criteria and enabling the general practitioner to evaluate PMV using conventional methods and to select potential patients from the general population. To empower one to perform needed activities we have developed a computer tool called ROSE (computeRised prOlaps Syndrom dEtermination) based on algorithms of automatic learning. This tool supports the definition of new criteria and the selection of potential PMV-patients. 相似文献

The syndactyly repairs of 11 hands in seven patients (average age 20.4) who had simple complete syndactyly between the third and fourth fingers were done by the use of tissue expanders in order to obtain adequate skin closure. At the first stage, a wedge type, 7 cc tissue expander was placed beneath the dorsal skin of the syndactylous digits via a vertical dorsal hand incision under local anesthesia. Inflation was begun on the 15th postoperative day. After the inflation period (average 32 days), syndactyly repair similar to the Littler technique was performed using axillary block anesthesia. During the expansion period one tissue expander became exposed and this hand was repaired by the classical skin grafting technique. In the remaining ten hands the expanded dorsal skin ensured skin closure of the digits and web reconstruction without any need for skin grafting. No complications were encountered during the postoperative period. Active and passive abduction angles, tip-to-tip length, active range of motion of the digits, and two point discrimination tests were done at follow-up (average six months). The web appearances were normal in all patients. Active abduction angles and active range of motion of the digits was always normal at the third postoperative month. Two point discrimination was 8.7 mm on the interdigital sides of the digits and there was no tip-to-tip length differences of the digits. No contractures were seen.Presented at the International Congress of Surgery of the Hand and Upper Extremity, Izmir, Turkey, September 25, 1994. 相似文献

Cytochemical analysis of leukemic blasts from 46 patients with acute myeloblastic M2 leukemia (according to the FAB classification)
was performed before and after cytostatic therapy, and compared with findings obtained in 20 age- and sex-matched control
subjects. Cytochemical findings for myeloperoxidase (MPO), Sudan black B, acid phosphatase and alpha-naphthyl-acetate esterase
(ANAE) were related to the achievement of the first complete remission (CR),i.e. data were compared after the patients had been divided into CR and non-CR groups. The analysis clearly showed that a high
proportion of myeloperoxidase- and, to a lesser extent, Sudan black B-positive blasts before treatment may have constituted
a significantly unfavourable prognostic factor. 相似文献

Circular stereotactic callosotomy: A preliminary report 总被引:1,自引:0,他引:1

Summary The authors propose a new method for performing Stereotactic callosotomy, which they have named circular callosotomy. The operating device is the original Riechert-Mundinger's string electrode, which can be protruded through a side window and by rotating the probe it is possible to cut the commisural pathways to the extent required. The anatomical results of the operation can be checked using MRI scanning. 相似文献
