A 45-year-old woman who suffered from juvenile tuberculous coxitis at the age of 4 is presented. Her hip joint replacement lasted for 18 years and then needed replacing. Intraoperatively removed caseous soft tissue and an opalescent secretion histologically resembled a tuberculous focus, and bacteriological culture grew a Mycobacterium tuberculosis strain. Four months after the replacement, the patient suffered from a tuberculosis-induced septic loosening of the newly replaced hip joint endoprosthesis. The tuberculosis relapse was probably due to aseptic loosening of the first hip joint endoprosthesis.
The novel NMR-MOUSE represents a cost efficient and portable sensor, which allows for a reliable evaluation of surface structures, such as the Achilles tendon. The anisotropic structure of the tendon and the surrounding soft tissue can be reliably differentiated with the help of the NMR-MOUSE.
Similar to other chronic inflammatory diseases such as rheumatoid arthritis the distribution of macrophage subtypes seems to be disturbed in post-traumatic osteomyelitis. This atypical distribution is clearly locally restricted in osteomyelitis. 27E10-positive macrophages found only during the acute phase of inflammation were reduced in 39%, the 25F9-positive subtype, predominating in the late stage of inflammation, was missing in 33%. The antiinflammatory macrophage RM3/1 was decreased in 40% of the osteomyelitis biopsies. Local suppression of macrophage subsets has to be discussed as one of the reasons for the persistence of chronic inflammatory processes in osteomyelitis.
With increasing life expectancy and better medical competence, the number of older patients with multimorbidity is growing. Patients with a deficient immune system need more attention during diagnosis and treatment of osteomyelitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
