Conclusion Quantification of nuclear cardiac images provides a secondary support in reading myocardial perfusion images and improves
the reproducibility in the diagnosis of cardiovascular diseases. The technology for the remote Web reading of nuclear cardiac
images and the quantitative data allows for an easy and secured access to patient studies without the limitations of time
and space. The recent increasing interests and applications in molecular targeted imaging have opened a new field in nuclear
cardiology, and absolute image quantification of the focal tracer uptake in the myocardium is exceedingly critical for the
quantitative analysis of molecular targeted images. 相似文献

CASE REPORT: A 12-year-old boy who had a history of Kawasaki disease 9 years ago experienced a subarachnoid hemorrhage by ruptured right posterior cerebral artery aneurysm. On day 1 operation, as the aneurysm was very fragile and bled easily, two intraoperative ruptures, including a very premature rupture, were encountered. As a result, a left hemiparesis especially severe in the left hand was caused by the right anterior thalamic infarction due to the occlusion of a thalamo-perforating artery arising near the neck of the aneurysm. DISCUSSION: The histopathological examination of the intraoperative excised aneurysmal dome disclosed the thickening of the endothelial inner due to the endothelial hypertrophy and the invasion of inflammatory cells. This finding of the aneurysm was partially mimicking the finding of the coronary artery of the patients with Kawasaki disease. The combination of cerebral aneurysm and Kawasaki disease has never been reported until now, and the etiology of the aneurysm of this patient is unclear. 相似文献

回盲部恶性肿瘤的诊治 总被引:1,自引:0,他引:1
目的:分析回盲部恶性肿瘤的诊断和治疗过程,总结经验.以期提高早期确诊率和患者生存率。方法:回顾性分析近5年53例住院治疗的回盲部恶性肿瘤患者的临床资料。结果:53例患者中腺癌、黏液腺癌50例,恶性淋巴瘤3例。首次确诊率为75.5%。误诊或延迟诊断的疾病主要为阑尾炎、阑尾脓肿,胆囊炎、胆石症、下消化道出血、贫血待查等。结论:60岁以上的老年患者为回盲部恶性肿瘤的主要人群,肿瘤类型主要为腺癌。尽管首发症状缺乏特异性,但提高警觉性,详细询问病史,通过大便隐血试验、钡灌肠或气钡双重造影、纤维结肠镜检查仍能有效的提高首次确诊率,积极手术冶疗,可显著改善患者的预后。 相似文献

Background
The telomeric region of mouse chromosome 12 has previously shown frequent allelic loss in murine lymphoma. The Bcl11b gene has been identified and suggested as a candidate tumor suppressor gene within this region. In this study, we aimed to elucidate whether Bcl11b is mutated in lymphomas with allelic loss, and whether the mutations we detected conferred any effect on cell proliferation and apoptosis. 相似文献75.

Abstract 10 embalmed cadaver forearms and wrists were dissected to determine the anatomical course of the superficial branch of the
radial nerve in the distal forearm. The superficial radial nerve bifurcated in two branches at a mean of 54,7 mm proximal
to the radial styloid. From the styloid process of the radius, the mean distance to the closest dorsal branch of the superficial
radial nerve was 3,5 mm and the mean distance to the closest volar branch was 9,8 mm. The mean distance between the closest
branch of the superficial radial nerve and Lister?s tubercle was 16,4 mm. The crossing point between the nerve and the cephalic
vein was located at a mean of 54,3 mm proximal to the styloid process. At the level of styloid process the mean distance between
the closest dorsal branch of the superficial radial nerve and the first dorsal compartment was 15,2 mm and between the closest
volar branch and the first dorsal compartment 4,4 mm. Detailed knowledge of anatomic characteristics of the superficial branch
of the radial nerve may help prevent injury during operations and treat traumatic lesions of the nerve. Because of great variations
in the course of the superficial radial nerve we could not define an absolute safe zone for surgical procedures on the distal
forearm. Iatrogenic lesions of the superficial radial nerve are described complications of percutaneous procedures. Therefore
open surgical approaches are recommended.

The purpose of this study was to determine the genetic characteristics of foot polydactyly and identify its inheritance pattern by analyzing familial pedigree. Five cases from 2 Korean families were studied: 1 is a family whose members have been affected for 4 generations and the other for 2 generations. Using peripheral blood samples, we performed chromosomal analysis using the banding technique with Giemsa stain and karyotyping. We investigated the shape and structure of 46 chromosomes, looking for translation, deletion, inversion, ring chromosome, and isochromosome abnormalities. All peripheral blood samples demonstrated no chromosomal abnormalities, though the genetic nature of foot polydactyly and a new genetic locus was identified recently by other studies. Familial pedigree analysis suggested that polydactyly was inherited as an autosomal dominant trait in the first family. The mode of inheritance for the second family could not be determined due to an insufficient number of family members. The result of this study brought us to the conclusion that, while genetic factors play a major role in polydactyly, other factors may contribute to its occurrence. 相似文献

Benign schwannoma of the pancreas 总被引:2,自引:0,他引:2

Reported cases of intrapancreatic schwannomas have recently increased in the literature. However, none of these cases were
diagnosed clearly as schwannoma preoperatively. We herein describe the clinicopathologic findings of a solitary benign schwannoma
occurring in the head of the pancreas. Additionally, the differential diagnosis versus other cystic- and solid-appearing pancreatic
masses is briefly discussed. 相似文献

Genetic studies on spontaneous mouse mutants with hearing defects have provided important insights into the function of genes
expressed in inner ear hair cells. Here we report on our genetic analyses of the deaf mutants varitint-waddler (Va) and jerker
(Espnje). A high-resolution genetic map localizes VaJ to a 0.14 ± 0.08 cM region between D3Mit85 and D3Mit259 on distal chromosome
3. By comparative mapping, the human ortholog resides at 1p22.3 between markers D1S3449 and D1S2252. To study the effect of
different genetic backgrounds on the hearing phenotype, Espnje and VaJ were crossed to various inbred strains. Auditory-evoked
brainstem response tests on F2 progeny demonstrate that expression, inheritance, and penetrance of the hearing phenotype are
solely controlled by the mutant allele. To test for a genetic interaction between Espnje and Cdh23v, auditory function was
analyzed in double heterozygotes; no significant increases of thresholds of sound pressure levels were observed. The results
establish the framework for cloning the Va gene and provide valuable insights into the genetics of deafness mutations in the
mouse. 相似文献
