BACKGROUND/AIMS: Phosphatase and the tensin homolog deleted on chromosome ten (PTEN) has been recognized as a promoter of apoptosis in various tissues and has been shown to be upregulated in circumstances of coronary microembolization (CME). We hypothesized that the upregulation of PTEN correlates with CME-induced myocardial apoptosis. METHODS: Swine CME was induced by an intracoronary injection of inert plastic microspheres (diameter of 42 μm) into the left anterior descending coronary, with or without pretreatment of the PTEN small-interfering RNA (siRNA)...

Cases of embolism after using hydrogen peroxide have been described in many circumstances in the operating room. Hydrogen peroxide is not more effective than other antiseptics; its potentially serious risk should not be unrecognized. The alternative use of saline seems very reasonable. The widespread use of hydrogen peroxide by practitioners is explained mainly by its antiseptic effect associated with effervescent backlash visual and auditory, but sometimes the liquid hiding behind a black hole that absorbs the life of the patient in case of inappropriate use...

UNLABELLED: Hypocalcemic cardiomyopathy in infants is characterized by heart failure in a previously normal infant with hypocalcemia without organic cardiac lesion. Vitamin D deficiency rickets is increasing in Middle East. In a six month study 136 cases of rickets were diagnosed in the main Children's Hospital in Almadinah but none of them showed evidence of cardiomyopathy. Concerned of missing this serious complication of rickets we searched pub med and present this review article. RESULTS: 61 cases of hypocalcemic cardiomyopathy were reported as case reports with two series of 16 and 15 cases from London and Delhi, respectively...

A 94-year-old woman was admitted to our hospital because of altered mental status and cerebellar ataxia of left upper and lower extremities. A brain CT scan revealed a right cerebellar hemorrhage approximately 15 cc. Plasma brain natriuretic peptide (BNP) value on admission was 1,064.6 pg/ml. Twelve-lead ECG revealed negative T-wave in V3-V5. Transthoracic echocardiology confirmed an ejection fraction of 35%, and left ventricular apical akinesia and basal hyperkinesis were seen. Plasma BNP value was dramatically declined in the subacute phase of cerebellar hemorrhage...

A 24-yr-old, male western lowland gorilla (Gorilla gorilla gorilla) was diagnosed with congestive heart failure using transesophageal and transthoracic echocardiology. New York Heart Association (NYHA) Class III was assigned to the severity of the condition. Over 16 mo, this progressed to NYHA Class IV despite increasing medical therapy. Repeated evaluations suggested that implantation of a cardiac resynchronization therapy device with a defibrillator (CRT-D) could benefit this animal based on clinical signs and underlying evidence of dyssynchrony and suspected fibrotic myocardial disease...

BACKGROUND: Hyperuricemia is frequently present in patients with heart failure. Many pathological conditions, such as tissue ischemia, renal function impairment, cardiac function impairment, metabolic syndrome, and inflammatory status, may impact uric acid (UA) metabolism. This study was to assess their potential relations to UA metabolism in heart failure. METHODS: We retrospectively assessed clinical characteristics, echocardiological, renal, metabolic and inflammatory variables selected on the basis of previous evidence of their involvement in cardiovascular diseases and UA metabolism in a large cohort of randomly selected adults with congestive heart failure (n = 553)...

PURPOSE: To demonstrate a simple low-cost system for tele-echocardiology, focused on paediatric cardiology applications. METHODS: The system was realized using open-source software and COTS technologies. It is based on the transmission of two simultaneous video streams, obtained by direct digitization of the output of an ultrasound machine and by a netcam showing the examination that is taking place. These streams are then embedded into a web page so they are accessible, together with basic video controls, via a standard web browser...

BACKGROUND/AIMS: Histological studies have provided evidence that carvedilol can prevent cardiac hypertrophy in spontaneously hypertensive-stroke prone rats (SP) fed a high-fat and -salt diet. However, the effects of carvedilol on cardiac function have not been studied in these animals. In addition, the ability of carvedilol to reverse established cardiac hypertrophy and dysfunction under these conditions remains to be determined. Here we have evaluated the ability of carvedilol to prevent and reverse cardiac hypertrophy and progressive dysfunction using echocardiography...

We created a Web catalogue of approved telemedicine systems that authoritative Italian research bodies had made available for more general use. The evaluation process was divided into two stages: (1) classification of the telemedicine systems and rough preliminary evaluation; (2) assessment of the telemedicine products and services. The scoring method was applied to four well-known telemedicine systems that had been tested in health-care settings: an echocardiology teleconsulting and analysis system; a ward nursing management system; a virtual cooperative system for the management of oncology patients and a telepathology system based on remotely controlled microscopy...
