Infectious spondylitis

BACKGROUND: Hepatic artery aneurysms (HAAs), albeit rare in infective endocarditis (IE), are associated with a life-threatening morbidity. METHODS: Retrospective review of 10 HAA-IE-patients based on a total of 623 IE-patients managed in two institutions (2008-2020) vs 35 literature' cases. RESULTS: In our patient population, HAAs (10 males, mean-age 48) were incidentally found during IE-workup. All were asymptomatic. IE involved mitral (n=6), aortic (n=3), or mitral-aortic valve (n=1)...

Spinal infections are a diverse group of diseases affecting different compartments of the spine with variable clinical and imaging presentations. Diagnosis of spinal infections is based on a combination of clinical features, laboratory markers, and imaging studies. Imaging plays a pivotal role in the diagnosis and management of spinal infections. The characteristic imaging manifestations of bacterial and viral infections in the spine are discussed with key teaching points emphasized.

Inflammasomes are intracellular multiprotein complexes that activate inflammatory signaling pathways. Inflammasomes comprise two major classes: canonical inflammasomes, which were discovered first and are activated in response to a variety of pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs), and non-canonical inflammasomes, which were discovered recently and are only activated in response to intracellular lipopolysaccharide (LPS). Although a larger number of studies have successfully demonstrated that canonical inflammasomes, particularly the NLRP3 inflammasome, play roles in various rheumatic diseases, including rheumatoid arthritis (RA), infectious arthritis (IR), gouty arthritis (GA), osteoarthritis (OA), systemic lupus erythematosus (SLE), psoriatic arthritis (PA), ankylosing spondylitis (AS), and Sjögren's syndrome (SjS), the regulatory roles of non-canonical inflammasomes, such as mouse caspase-11 and human caspase-4 non-canonical inflammasomes, in these diseases are still largely unknown...

OBJECTIVE: To evaluate the effect of adalimumab (ADA) on choroidal thickness (ChT) and choroidal vascularity index (CVI) in eyes with non-infectious uveitis (NIU).

RESULTS: There were 40 adult patients identified with the discharge diagnosis of PA...

BACKGROUND: Tuberculous (TB) spondylitis is a hazardous infectious disease causing significant spinal deformity. Increased toll-like receptor-4 (TLR-4) activity promotes more extensive infections in patients with TB spondylitis, so it has the potential to be used as a biomarker to predict the severity. This study aims to determine the relationship between TLR-4 levels and the degree of vertebral destruction in TB spondylitis patients. MATERIALS AND METHODS: A cross-sectional study was conducted from May to October 2023...

INTRODUCTION: Brucellosis is an infectious illness contracted by humans through the consumption of unpasteurized milk and dairy items. Brucella organisms are diminutive, gram-negative, non-motile, and non-spore-forming facultative intracellular, aerobic intracellular coccobacilli residing within the reproductive organs of host animals, leading to conditions such as abortions and sterility. Numerous species of Brucella have been identified, with the following four exhibiting varying degrees of pathogenicity in humans: Brucella melitensis (originating from sheep), Brucella suis (associated with pigs), Brucella abortus (linked to cattle), and Brucella canis (found in dogs)...

BACKGROUND: Pyogenic spondylitis (PS) and Brucella spondylitis (BS) are commonly seen spinal infectious diseases. Both types can lead to vertebral destruction, kyphosis, and long-term neurological deficits if not promptly diagnosed and treated. Therefore, accurately diagnosis is crucial for personalized therapy. Distinguishing between PS and BS in everyday clinical settings is challenging due to the similarity of their clinical symptoms and imaging features. Hence, this study aims to evaluate the effectiveness of a radiomics nomogram using magnetic resonance imaging (MRI) to accurately differentiate between the two types of spondylitis...
