Osteomyelitis frequently requires more than one imaging technique for an accurate diagnosis. Conventional radiography still remains the first imaging modality. MRI and nuclear medicine are the most sensitive and specific methods for the detection of osteomyelitis. MRI provides more accurate information regarding the extent of the infectious process.(More)
We reviewed the clinical features of 26 children with Takayasu's arteritis. In contrast to what is often seen in adults, in this age group inflammation of different systems is a conspicuous feature. Eighty five percent of cases had arterial hypertension. The high incidence of arthritis and heart failure provoked confusion with rheumatic fever. There was a(More)
The diagnostic imaging of osteomyelitis can require the combination of diverse imaging techniques for an accurate diagnosis. Conventional radiography should always be the first imaging modality to start with, as it provides an overview of the anatomy and the pathologic conditions of the bone and soft tissues of the region of interest. Sonography is most(More)
OBJECTIVE To produce consensus-based definitions of the US elementary lesions in gout and to test their reliability in a web-based exercise. METHODS The process consisted of two steps. In the first step a written Delphi questionnaire was developed from a systematic literature review and expert international consensus. This collated information resulted in(More)
Rheumatic and musculoskeletal diseases (RMDs) represent a multitude of degenerative, inflammatory and auto-immune conditions affecting millions of people worldwide. Persons with these diseases may potentially experience severe chronic pain, joint damage, increasing disability and even death. With an increasingly ageing population, the prevalence and burden(More)
Alkaptonuria is a rare, hereditary metabolic disorder in which a deficiency in the homogentisate 1,2-dioxygenase enzyme results in an accumulation of homogentisic acid. Deposition of excess homogentisic acid in different intra- and extra-articular structures with high content of connective tissue causes brownish-black pigmentation and weakening, ultimately(More)
Ultrasonographic characteristics of two common musculoskeletal lesions, ganglion cysts (GCs) and synovial cysts (SCs) are presented through a review of the literature. Although similar in many ways, these two lesions display different morphostructural characteristics justifying, in our view, their descriptions as separate entities. Mainly different from an(More)
At the end of 2013, the Pan American Health Organization issued an epidemiological alert due to the detection of the first local cases of Chikungunya in the Americas. By August 2015, autochthonous transmissions were detected in 33 countries and territories of the Americas. Latin America has reported nearly one million cases; only Colombia has issued a(More)
Larvae of the brine shrimp Artemia franciscana serve as important feed in fish and shellfish larviculture; however, they are subject to bacterial diseases that devastate entire populations and consequently hinder their use in aquaculture. Exposure to abiotic stress was shown previously to shield Artemia larvae against infection by pathogenic Vibrio, with(More)
