Summary Conventional imaging with computed tomography (CT) and magnetic resonance imaging (MRI) may show abnormalities in central nervous system Behcet's syndrome but is normal in some cases. Recently in two cases positron emission tomography has shown abnormalities in blood flow and glucose metabolism far more extensive than the abnormalities seen on CT and MRI scans in the same patients. We report a patient with neuro-Behcet's syndrome presenting with headache and personality change in whom CT and MRI brain imaging was normal, but regional cerebral blood flow imaging using single photon emission tomography with the tracer HMPAO showed extensive perfusion deficits which partially reversed after 3 months of prednisolone therapy. This technique may aid the diagnosis of cerebral involvement in Behcet's syndrome, although the cause and incidence of the perfusion deficits need further evaluation. 相似文献

Intravenously injected 99mTc-DTPA was evaluated in 64 patients for its efficiency in detecting and localizing sites of acute upper and lower gastrointestinal (G.I.) bleeding. These studies were correlated with endoscopic and surgical findings. There were 34 bleeders and 30 non bleeders giving a sensitivity of 90%, specificity of 82% and accuracy of 86%. Of these, 49 were upper G.I. studies (stomach 21 and duodenum 28) and 15 were lower G.I. studies (small intestine 8, large bowel 7). Of the 49 upper G.I. studies, 27 showed active bleeding while 22 showed no bleeding at the time of the study resulting in a sensitivity of 87.5%, specificity of 76% and accuracy of 82%. Of the 15 lower G.I. studies, 7 were bleeders while 8 were non bleeders. All the lower G.I. bleeding sites were accurately localized with the 99mTc-DTPA. An incidental finding of these studies was the localization of 99mTc-DTPA in the site of inflammatory and malignant lesions of the G.I. tract. Of the 64 studies, 18 inflammatory and malignant lesions were detected with the IV injected 99mTc-DTPA; 10 were bleeders while 8 were non bleeders. Image subtraction of early from delayed images was helpful to differentiate bleeding from non bleeding cases in this last group of studies. 相似文献

Summary This study deals with 49 fractures of the dens treated at the Orthopedic Department of Athens University during the past 17 years. These fractures represent 14.2% of all cervical fractures treated during the same period at our department. Forty-one cases have been reviewed and analyzed, the average follow-up time being 10 years (1–16). Pseudarthrosis was found to be present in seven cases (17%), and its relationship to different factors was examined. The type of fracture and particularly the direction of the fracture line were found to be major factors leading to pseudarthrosis. Many other factors, such as displacement, traction, the stability obtained, the presence of associated injuries, and the time elapsed till treatment was started, as well as the age of the patients, seem to play — alone or in combination — important roles in the development of pseudarthrosis. These factors have been classified according to their importance and graded. With a total of 10 points or more a dens fracture is characterized as a fracture at risk of pseudarthrosis, i.e., a fracture with a higher possibility of developing a pseudarthrosis. This knowledge may contribute to proper and earlier management of such an injury. 相似文献

Leg ulcers have been shown to have a significant impact on a patient's quality of life (QoL). Little is known, however, about the secondary impact of the disease on the QoL of the relatives and partners of patients with leg ulcers. The aim of this study was to explore the impact of chronic leg ulcers on the lives of both patients and their family members. Two hundred sixteen patients with leg ulcers and their family members were recruited. All patients entered were evaluated for QoL using the Dermatology Life Quality Index (DLQI) scale, and family members were similarly evaluated using the Family Dermatology Life Quality Index (FDLQI).The study included 56 female and 52 male patients, and 50 female and 58 male family members. The FDLQI score for the latter group was 14.37 ± 2.46 with over 96% of family members reporting a large effect on their QoL due to their relative's disease. The DLQI score in patients with leg ulcers was 13.18 ± 2.88. A significant positive and high correlation between DLQI and FDLQI scores (r = 0.71, p < 0.001) was documented, while DLQI contributed significantly to the prediction of FDLQI (standardized β = 0.71, p < 0.001). Our study results indicate that the QoL of the family was also affected by the patient's condition of chronic leg ulcers and clearly associated with that of the patients. 相似文献

We report a case of an acute ST-T elevation myocardial infarction in a middle-aged female with a mechanical mitral valve prosthesis and subtherapeutic INR levels. We performed a primary coronary intervention, using a thromboaspiration catheter. After blood clot aspiration, a TIMI III flow was restored and no residual lesions remained at the site of the occlusion. A transesophageal echo revealed a movable thrombus over the mechanical mitral valve prosthesis and patient underwent subsequent mitral valve replacement. Embolic myocardial infarction remains underdiagnosed. A high level of suspicion and the quest of the source of embolus are crucial. 相似文献

Comparative study of plasma ghrelin levels in women with polycystic ovary syndrome, in hyperandrogenic women and in normal controls 总被引:3,自引:0,他引:3
Panidis D Farmakiotis D Koliakos G Rousso D Kourtis A Katsikis I Asteriadis C Karayannis V Diamanti-Kandarakis E 《Human reproduction (Oxford, England)》2005,20(8):2127-2132
BACKGROUND: Ghrelin is a novel peptide associated with energy balance, obesity, and perhaps gonadal function. The present study was designed in order: (i) to compare plasma ghrelin levels between women with PCOS, women who presented only with hyperandrogenaemia and healthy controls; and (ii) to investigate the relationship between circulating ghrelin and the heterogeneity of clinical and biochemical manifestations of PCOS. METHODS: Two hundred and fifty-nine women with PCOS, 25 women who had only hyperandrogenaemia and 46 controls, were studied. Women with PCOS were further divided, based on the presence of chronic anovulation, biochemical hyperandrogenaemia, clinical hyperandrogenism, and polycystic ovary morphology on ultrasound evaluation. In all women, the basal levels of gonadotrophins, androgens, 17-OH-progesterone, sex hormone-binding globulin, glucose, insulin and ghrelin were measured. RESULTS: Women with PCOS had lower ghrelin levels, compared to both women with hyperandrogenaemia and controls; women with hyperandrogenaemia had lower ghrelin levels, compared to controls, but not significantly so. While PCOS-associated hyperandrogenaemia was inversely related to ghrelin levels, anovulation and polycystic ovary morphology were associated with higher concentrations. Ghrelin levels were negatively correlated with 17-OH-progesterone levels. CONCLUSIONS: In PCOS, circulating ghrelin and androgens are inversely related and it is possible that this peptide is involved in steroidal synthesis and/or action. It is also likely that different clinical and biochemical manifestations of the syndrome are also associated with different ghrelin concentrations. 相似文献

DESIGN: We examined 16 men who had been subjected to unilateral orchiectomy owing to seminoma and to preventive radiotherapy, in order to investigate the morphologic abnormalities of the spermatozoa (headless and small-round-headedness) that may contribute to infertility. RESULTS: The same morphologic abnormalities of the head and neck found in the semen samples of fertile men were also found in the semen samples of the patients, albeit in higher percentages; the morphologic abnormalities of the tail in the semen samples of the patients were similar to those of the fertile men, both qualitatively and quantitatively. CONCLUSION: No specifically characteristic morphologic abnormalities of the spermatozoa were detected in men who were subjected to unilateral orchiectomy and to preventive radiotherapy in comparison with fertile men. The percentage rate of morphologic tail abnormalities is not affected by preventive radiotherapy. 相似文献
