“…While we recognize through the review of pathogenic mechanisms of extrapulmonary tuberculosis that the primary involvement of the biceps tendon is unlikely, there is no way to confirm in this case whether the osteoarticular infection preceded the tendon involvement or vice versa. In fact, no case of isolated bicipital tendinitis tuberculosis was found during the literature review done in the preparation of this report, although many authors have reported other atypical locations 19 , 20 , 28 , 29 , 31 , 32 , 33 , 34 . Only one third of patients with musculoskeletal tuberculosis have a history of pulmonary disease (4) , although the presence of findings consistent with previous tuberculosis is common in imaging studies (chest radiography and computed tomography) 7 , 23 .…”

Objective: The authors report a rare case of disseminated tuberculosis which had compromised the long head of biceps tendon and shoulder joint, during standard drug therapy. Methods: On a first sight, the accurate diagnosis wasn't accomplished and the patient had been treated with physiotherapy for rotator cuff tear. However, the patient presented with a fast growing mass in anterior region of the proximal third of the arm, complaining of pain increase. Aspirative punction of the mass revealed a yellow fluid and the laboratorial analysis confirmed infection by M. Tuberculosis. The patient was treated with surgical debridement and his drug therapy was changed. Results: Resolution of infectious status and complete shoulder function restoration was succeeded. Conclusion: Due to its high prevalence in Brazil, tuberculosis must always be considered as a possible cause of inflammatory joint disease, even in immunocompetent patients.

“…After the hematogenous dissemination of mycobacterium tuberculosis, it is easy to cause inflammation, hyperemia, edema and exudation of tendon sheath and synovium. (10) In the development of tuberculous tenosynovitis, inflammatory secretions can be changed into serous cellulosic exudates. The lesion starts from the synovium of the tendon sheath and the inflammatory exudate and caseous necrotic lesions gradually enlarge in the synovial cavity to form masses.…”

Background: Tuberculosis is a significant public health challenge and tuberculous tenosynovitis is therefore a rare form of musculoskeletal tuberculosis which usually affects the flexor tendons of the hand and wrist. Case presentation: We present a case of a 63-year-old male. He presented multiple progressively enlarging mass over the volar side of the right hand and wrist. He did not have a previous history of tuberculosis. However, his erythrocyte sedimentation rate was high and tuberculosis antibody test was slightly positive. Radiograph of chest showing multiple nodular and patchy dense shadows in bilateral lungs, and localized soft tissue mass around the radiocarpal joint. Excision biopsy of the mass was done and samples sent for histopathology comment. The findings were an inflamed, thickened synovia: suggestive of tuberculous tenosynovitis. Anti-tuberculous chemotherapy was commenced on the second postoperative day. Conclusion: Tuberculous tenosynovitis of the wrist is rare. However, in developing area where tuberculosis is prevalent, it should be part of the differential diagnosis of compound palmar ganglion in order to prevent delayed diagnosis and treatment.

“…Exposure of B2M has certain toxicity in nervous system of human beings, recognized as a useful marker in early diagnosis and monitoring of brain metastasis in malignant disease (Alsobhi et al, 2007; Hansen et al, 2009). Research has shown that B2M, a systemic pro-aging factor, negatively regulates neurogenesis in the hippocampus (Smith et al, 2015).…”

Background and AimAccumulation of β2-microglobulin (B2M), a systemic pro-aging factor, regulates negatively cognitive function. Hydrogen sulfide (H2S), a novel gas signaling molecule, exerts protection against cognitive dysfunction. Therefore, the present work was designed to explore whether H2S attenuates cognitive dysfunction induced by B2M and the underlying mechanism.Materials and MethodsThe cognitive function of rats was assessed by Y-maze, Novel object recognition (NOR), and Morris water maze (MWM) tests. The levels of autophagosome and autolysosome in hippocampus were observed by transmission electron microscopy. The expression of p62 protein in hippocampus was detected by western blot analysis.ResultsNaHS (a donor of H2S) significantly alleviated cognitive impairments in the B2M-exposed rats tested by Y-maze test, NOR test and MWM test. Furthermore, NaHS recovered autophagic flux in the hippocampus of B2M-exposed rats, as evidenced by decreases in the ratio of autophagosome to autolysosome and the expression of p62 protein in the hippocampus.ConclusionIn summary, these data indicated that H2S attenuates B2M-induced cognitive dysfunction, involving in recovery of the blocked autophagic flux in the hippocampus, and suggested that H2S may be a novel approach to prevent B2M-induced cognitive dysfunction.
