Live/real time three-dimensional transesophageal echocardiographic assessment of ventricular septal volume and mass before and after myectomy in hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is the most common genetically transmitted cardiomyopathy. In patients resistant to medical management, myectomy is the surgical procedure of choice to reduce the symptoms of left ventricular outflow obstruction. Two-dimensional transesophageal echocardiography (2DTEE) has become part of the operative procedure by decreasing the incidence of postoperative complications.

Cellular interferon-gamma based assay for diagnosis of pulmonary tuberculosis.

A major breakthrough in recent years has been the development of an in vitro assays that measure T-cell release of interferon gamma (IFN-gamma) in response to stimulation with antigens specific to Mycobacterium tuberculosis (MTB) such as early secreted antigenic target 6 (ESAT6) and culture filtrate protein 10 (CFP10). This study aimed at evaluating the diagnostic potential of IFN-gamma in vitro production assay for diagnosis of pulmonary tuberculosis. The study included 40 patients from Abbasia Chest Hospital, Cairo, Egypt.
