Intracardiac masses are rare in infants and children. Early detection is essential to their successful management. We present seven patients in whom echocardiography established the diagnosis and was crucial in the management. Three of the masses were primary cardiac tumors and four were thrombi. Patient 1: an infant with a calcified left ventricular fibroma. Patient 2: a neonate who presented with cyanosis due to obstruction of the right ventricular inflow tract by a fibroblastic tumor. Patient 3: an infant with a right atrial myxoma presenting as sepsis. Patient 4: a child who had a pulmonary embolus after a pulmonary valvotomy and was found to have a right ventricular thrombus. Patient 5: a child with a right atrial thrombus following a Fontan procedure for univentricular atrioventricular connection. Patient 6: a child with a left ventricular thrombus due to a dilated cardiomyopathy in association with epidermolysis bullosa. Patient 7: An infant with bilateral lobar emphysema, an aorticopulmonary window with left ventricular fibroelastosis, who developed a left ventricular thrombus.

Matrix metalloproteinases (MMPs) have a great variability that provides a complex intervention in pathophysiological conditions. MMPs roles in pathology may be grouped into the following main types: (1) tissue destruction, as in cancer invasion and metastasis, rheumatoid arthritis, osteoarthritis, different types of ulcers, periodontal disease, brain injury and neuroinflammatory diseases; (2) fibrosis, as in liver cirrhosis, fibrotic lung disease, otosclerosis, atherosclerosis, and multiple sclerosis; (3) weakening of matrix, as in dilated cardiomyopathy, epidermolysis bullosa, aortic aneurysm and restenotic lesions. Recent data also adds new MMPs functions in angiogenesis and apoptosis. Interesting opposite intervention in escaping mechanisms vs. antitumor defensive mechanisms had been also reported. As MMP-7 is expressed by tumor cells of epithelial and mesenchymal origin, it may be used as a biological marker of an aggressive phenotype and as a target of therapeutic intervention. MMPs play a pivotal role in the pathogenesis of arthritis, atherosclerosis, pulmonary emphysema, and endometriosis. Although MMP involvement in pathology is more than simple excessive matrix degradation, or an imbalance between them and their specific tissular inhibitors (TIMPs), MMP inhibition may be of therapeutic benefit, so synthetic MMPs inhibitors had been developed and are currently under clinical testing.

A 49-year-old female visited our hospital with a complaint of pelvic pain. She was under treatment for diabetes mellitus and dilated cardiomyopathy. Radiography revealed a radiolucent area in the bladder. We suspected vesicorectal fistula. Computed tomography showed gas within the bladder wall and the lumen. Cystoscopy revealed diffuse emphysema in the bladder wall without fistula. These findings were consistent with a diagnosis of emphysematous cystitis. The urine culture yielded Escherichia coli. After urinary drainage and antibiotic therapy, she was cured of emphysematous cystitis.

Systemic sclerosis (SSc) sine scleroderma (ssSSc) is characterized by the absence of skin involvement, despite other manifestations of systemic sclerosis are present. It is not known whether sSSc represents a forme fruste of limited cutaneous SSc or a distinct entity, but the 2013 American College of Rheumatology/European League Against Rheumatism criteria for the classification of SSc have considered SSc without skin involvement to be a distinct subset. The authors present the case of a 70-year old female that was referred for a consultation for Raynaud's phenomenon and a chronic anterior uveitis (CAU). She had a history of dysphagia, diffuse pulmonary emphysema and a biopsy-documented fibrosis of the upper lobes, and an idiopathic non-ischemic dilated cardiomyopathy with severe left ventricle systolic dysfunction and left bundle branch block. Anti-nuclear and anti-centromere antibodies were positive, while manometry revealed distal esophageal hypomotility. After establishing the diagnosis of ssSSc and starting immunosuppression, the ocular disease improved, while the lung and heart diseases remained stable. This case underlines that it is very important to suspect SSc when CAU is present and/or skin thickening is absent. To our knowledge, this is the first report of CAU in a patient with ssSSc.
