Case report<br>Left atrial myxoma crossing the mitral valve

In this article, we report a 79-year-old man with a large mobile and pediculated mass in left atrium crossing the mitral valve in diastol and enter the left ventricle. Transthorasic two-dimensional echocardiography showed the big neoplastic mass attached to interatrial septum (IAS) and measured 7x4.5 cm. The patient presented signs and symptoms of Transient Ischemic Attack (TIA) with aphasia, dysphagy suddenly developed 24 hours earlier to admission. Brain axial CT scan showed a hypodense area in the left parietal lobe and a hypodense trigonal shaped area in the left temporal lobe. The surgical approach used for resection of this tumour was an isolated left atriotomy that provided excellent exposure and safe excision

Short Communication<br>Immunization coverage of health care workers against hepatitis B

Introduction: Hepatitis B virus (HBV) infection remains a serious risk for health care workers (HCWs). Vaccination of the group against HBV therefore is a central part of programs to prevent nosocomial infections in healthcare workers. An evaluation of the anti-HBs level in vaccinated persons is a necessary measurement to handle immunization coverage. Material and methods: We evaluated the Anti-HBs level of 100 randomly selected HCWs in an Educational Hospital 6 months after implementing a vaccination program against HBV to handle the immunization coverage of HBV in the group. Results: 90 (90%) HCWs responded to the immunization program that 72 (72.0%) had anti-HBs titers in an equal range (>10 MIu/L), 18 (18%) were <10 MIU/L and 10 had negative anti-HBs. Conclusions: Immunization coverage should be assessed to find out low-responded or non-responded healthcare workers to immunization. Some factors such as age, gender, race and storage conditions of vaccine may interfere with one’s response to immunization
