We report an unusual form of chorioretinal anastomosis in a 20-year-old man with chronic recurrent Vogt-Koyanagi-Harada syndrome. Several subretinal optic disc-like lesions of subretinal fibrosis were found in the vicinity of the equator. No evidence of neovascularization or arteriovenous shunt was noted.  相似文献

Bone and soft tissue tumours are rare neoplasms. There are five major roles of imaging in the management of primary musculoskeletal tumours, that is, to differentiate between benignity and malignancy, to evaluate for local tumour extension, to screen for metastases, to judge the effect of chemotherapy, and to monitor for recurrence. To accomplish this, multiple modalities are required because no single examination is able to complete all these tasks. These modalities include plain radiography, CT, MRI, conventional nuclear medicine as well as positron emission tomography (PET) imaging. Elsewhere, PET imaging has been discussed at length, because it is likely to be superior in the assessment of bone and soft tissue tumours over conventional nuclear medicine procedures. However, conventional nuclear medicine may be of value when PET is unavailable. In this review, an overview of anatomical imaging will be given and the role of non‐PET functional imaging will be discussed in detail. A variety of illustrative cases will be presented.  相似文献

Hyperoxaluria is frequently seen in patients with inflammatory bowel disease, or after resection of the ileum. It is assumed to be responsible for the development of nephrolithiasis, nephrocalcinosis (oxalate nephrosis) and progressive renal impairment in these patients. Steatorrhea may aggravate the severity of hyperoxaluria. A 60-year-old male underwent massive resection of the jejunum and ileum 10 years prior to admission, due to strangulation of the small bowel, with occlusion of the superior mesenteric artery. He remained well except for steatorrhea which developed two-and-a-half years prior to admission, when microhematuria, proteinuria and oxaluria developed progressively. Since that time, the nephrolithiasis, nephrocalcinosis and renal failure have continued to worsen despite therapy with oxalate restriction and oxalate-binding agents. A renal biopsy, performed late in the clinical course, showed severe changes in the renal parenchyma. The decline in renal function proved irreversible. The unusual metabolic consequences of massive resection of the small intestine and their mechanisms are discussed.  相似文献

OBJECTIVES: This paper aims to report the methodology of a study of a cohort of middle-aged women in Taiwan, their age at menopause, and related factors and prevalence of menopausal symptoms, and to examine the relationships between symptoms and sociodemographic variables. METHODS: An epidemiological study of neuropsychological change during the menopausal transition among Chinese women aged 40-54 years old on the islet of Kinmen. RESULTS: Of a targeted population of 2256 individuals, 1497 (66%) participated in the study. The mean age at menarche was 15.6 years and that at menopause was 48 years. The hormone use rate at the time of study was 23% in surgical menopausal women, and 9% were past users. After excluding surgical menopausal and premenopausal women, 6% reported a current use of estrogen replacement therapy and 6% were past users. The most frequently reported discomforts for those women aged >45 were troubled sleep, backaches, and joint pain. Four symptom clusters: musculoskeletal, non-specific somatic complaints, urogenital, and vasomotor, were identified. After adjustment for age, the urogenital and vasomotor symptoms were significantly associated with menopausal status. CONCLUSIONS: The age at menopause did not differ much from Western studies, but the menopausal symptoms, especially the vasomotor symptoms, were much lower in our study population. Nevertheless, vasomotor symptoms were still significantly associated with menopausal status.  相似文献
