Myocardial calcification is a life-threatening condition that is a recognised complication of ischaemic heart disease, cardiac surgery, rheumatic fever, myocarditis and sepsis. Only sparse data, reporting the clinical symptoms, the anatomo-pathological findings, the imaging findings have been published and no exhaustive analysis of all these factors exists in literature. To date, there have been 26 published cases in the medical literature in which myocardial calcifications is the consequence of a septic status. In this review, we will describe the main imaging and histological findings, with particular attention to the known and hypothesized mechanisms of myocardial calcifications. The results of this study may help clinicians and forensic pathologists to identify possible unrecognized cases and inspire the development of an international registry by which to coordinate further research.CD39 (nucleoside triphosphate diphosphohydrolase) and Ecto-5-nucleotidase (CD73) have been recognized as important factors mediating various pathological and physiological responses in the tumor microenvironment. Elevated expression of CD73 and CD39 is correlated with the over-production of adenosine in the tumor region. This increase is associated with an immunosuppressive state in the tumor site that enhances various tumor hallmarks such as metastasis, angiogenesis, and cell proliferation. Adenosine promotes these behaviors through interaction with four adenosine receptors, including A3R, A2BR, A2AR, and A1R. Signaling of these receptors reduces the function of immune effector cells and enhances the expansion and function of tumor-associated immune cells. Several studies have been shown the important role of adenosine/CD73/CD39/ARs axis in the immunopathogenesis of colorectal cancer. These findings imply that components of this axis can be considered as a worthy target for colorectal cancer immunotherapy. In this review, we summarized the role of CD73/CD39/adenosine/ARs in the immunopathogenesis of colorectal cancer. Fibroblast dysfunction is the main pathogenic mechanism of idiopathic pulmonary fibrosis (IPF). S100 calcium-binding protein A4 (S100A4) plays critical roles in the proliferation of fibroblasts and in the development of pulmonary, hepatic, and renal fibrosis. However, the clinical implications of S100A4 in IPF have not been evaluated. The S100A4 mRNA and protein levels were measured by real-time PCR and immunoblotting in fibroblasts from IPF patients and controls. The S100A4 level was measured by enzyme-linked immunosorbent assay in bronchoalveolar lavage fluid (BALF) from the normal controls (NCs; n = 33) and from patients with IPF (n=87), non-specific interstitial pneumonia (NSIP; n=22), hypersensitivity pneumonitis (HP; n=19), and sarcoidosis (n=9). S100A4 localization was evaluated by immunofluorescence staining. The S100A4 mRNA and protein levels were significantly higher in fibroblasts from IPF patients (n=14) than in those from controls (n=10, p<0.001). The S100A4 protein level in BALF was significantly higher in the IPF (89.25 [49.92-203.02pg/mL]), NSIP (74.53 [41.88-131.45pg/mL]), HP (222.36 [104.92-436.92pg/mL]) and sarcoidosis (101.62 [59.36-300.62pg/mL]) patients than in the NCs (7.57 [1.31-14.04pg/mL], p<0.01, respectively). Cutoff S100A4 levels of 18.85 and 28.88pg/mL had 87.4% and 87.8% accuracy, respectively, for discriminating IPF and other lung diseases from NCs. S100A4 is expressed by α-SMA-positive cells in the interstitium of the IPF patients. S100A4 may participate in the development of IPF, and its protein level may be a candidate diagnostic and therapeutic marker for IPF.
