A 76-yr-old man developed necrotizing fasciitis due to Salmonella enteritidis 1 month after an episode of gastroenteritis due to the same microorganism. The fact that S. enteritidis was the only organism isolated despite adequate anaerobic cultures confirm the ability of salmonellae to produce severe monomicrobial soft tissue infections. 相似文献

The present report describes a patient with polycythemia vera who developed a severe arterial and venous thrombosis caused by systemically administered heparin. An immunologic implication has been proposed as pathophysiological mechanism of this heparin-associated thrombocytopenia and thrombosis syndrome. It is suggested, however, that a strong decrease in platelet count as occurred in this patient leads to a higher chance of developing this complication. 相似文献

One hundred and fifteen persons with asymptomatic Entamoeba histolytica or E. hartmanni infection, or both, were given metronidazole (750 mg three times daily for 5 days), tinidazole (1 g twice daily on 2 consecutive days), or a starch placebo. Three post-treatment stools were examined in the 2 weeks following initiation of treatment. Cysts of E. histolytica reappeared in the stools of 37% of 30 given metronidazole, 62% of 34 given tinidazole, and 70% of 31 given placebo. Cysts of E. hartmanni reappeared in the stools of 46% of 24 given metronidazole, 69% of 16 given tinidazole, and 90% of 10 given placebo. Rapid absorption and short duration of treatment make both drugs ineffective for the treatment of ameba carriers. 相似文献

Situs inversus, a condition in which the major visceral organs are reversed from their normal positions in the body, can be detected by prenatal ultrasonography. Often benign, it may be associated with primary ciliary dyskinesia, an autosomal recessive disorder characterized by chronic respiratory disease. Yet, prenatal diagnosis of primary ciliary dyskinesia has not been reported. We describe a pregnancy in which situs inversus was diagnosed by fetal ultrasound at 20 weeks gestation. Prenatal testing for primary ciliary dyskinesia led to the discovery that both parents were asymptomatic carriers of a pathogenic mutation in the CCDC103 gene, with an affected neonate. 相似文献

A 51-year-old man with a history of stage IV angioimmunoblastic T-cell lymphoma was diagnosed with osteomyelitis of the patella. Legionella anisa was identified by 16S rRNA gene sequencing and culture. The patient had pneumonia 2 months prior to this osteomyelitis episode. L. anisa was retrospectively detected in his lung tissue by 16S rRNA gene sequencing and was considered the source of the L. anisa that caused his patella osteomyelitis. 相似文献

IntroductionExtravasation or partial extravasation of the positron emission tomography (PET) tracer negatively effects image quality in PET and the accuracy of the standard uptake value (SUV). A commercially available topical sensor has been validated using a number of metrics to characterise injection quality. This evaluation explores contributing factors for extravasation and refines metrics to predict extravasation based on the time-activity-curves (TAC) of the topical sensor device.MethodsA multi-site, multi-national pooling of 18F FDG PET/CT data was undertaken with 863 patients from 6 sites in the USA and 2 sites in Australia. A number of dose migration metrics determined with topical application of Lara sensors were retrospectively analysed using conventional statistical analysis. Deeper insights into the complex relationship between variables was further explored using an artificial neural network.ResultsExtravasation was independently predicted by the time taken for the injection sensor counts to reach double the counts of the reference sensor (tc50), the normalised difference between injection and reference sensors counts at 4 min post injection (ndAvgN), or the ratio of injection sensor counts to reference sensor counts at the end of data collection (CEnd ratio). The algorithm developed using the artificial neural network produced 100% sensitivity and 100% specificity against grounded truth for detecting extravasation by weighting and scaling these 3 key metrics; CEnd ratio, ndAvgN and tc50.ConclusionPartial extravasation of a PET dose is readily detected and differentiated using TAC metrics and these metrics could provide deeper insight into the impact of partial extravasation on image quality or quantitation. Further validation of key metrics developed in this study are recommended in a larger and more diverse cohort.Implications for practicePartial extravasation undermines image quality and accuracy of quantitation, impacting efficacy of outcomes for patients. Characterisation of extravasation informs decision making to optimise protocol and procedure, enhancing patient outcomes. Awareness provides the opportunity for education and training to minimise impact. The information can be used to drive policy and regulations to support improved techniques in practice. 相似文献

Gangliogliomas are well-differentiated, slow-growing tumors. The majority are grade I of WHO. It appears predominantly in children and young adults. Most are located at the temporal lobe, and as symptomatology more frequent epileptic seizures of difficult pharmacological control. In general, they have a good prognosis after surgical resection. The anaplasic variant, considered to be grade III of the WHO, presents greater clinical and radiological aggressiveness. Leptomeningeal dissemination is exceptional in these types of tumors, but when diagnosed it presents a rapidly progressive and fatal course for the patient. 相似文献
