Effects of propofol versus isoflurane on liver function after open thoracotomy.

Background: Anesthetic agents and type of surgery may contribute to postoperative hepatic injury. Inhalational anesthetics have been associated with hepatic dysfunction after surgery, however, propofol is expected to have a lower potential for postoperative liver injury. This prospective double-blind randomized clinical study was planned to determine whether postoperative liver function differs after anesthesia with isoflurane and total intravenous anesthesia with propofol in patients undergoing a posterolateral thoracotomy.

No association between simian virus 40 and diffuse malignant mesothelioma of the pleura in Iranian patients: a molecular and epidemiologic case-control study of 60 patients.

Background: Diffuse malignant mesothelioma (DMM) is increasing in incidence on a worldwide basis and is linked to exposure to asbestos. Simian virus 40 (SV40), a DNA virus, was introduced inadvertently to human populations through contaminated polio vaccine during the years 1956-1963. It has been associated with various types of malignancy in animal experiments.

Incidence of fever and bacteriemia following flexible fiberoptic bronchoscopy: a prospective study.

The latest American Heart Association (AHA) statement for preventing infectious endocarditis, has not recommended prophylactic antibiotic therapy prior to fiberoptic bronchoscopy (FB) except for patients with preexisting predisposing cardiac conditions. Our aim was to determine the incidence of bacteriemia and fever following FB in our experience and compare with those which have been mentioned in AHA guideline as well as other studies. Venous blood of 85 consecutive patients was evaluated for both aerobic and anaerobic cultures before (for detecting possible previous bacteriemia) and after FB.

Surveillance of antimicrobial susceptibility among bacterial isolates from intensive care unit patients of a tertiary-care university hospital in Iran: 2006-2009.

Background: This study was conducted to determine the antimicrobial susceptibility patterns among common pathogens in the intensive care unit (ICU) of a university hospital in Iran between 2006 and 2009.

Methods: The isolates cultured in appropriate media and antimicrobial susceptibility were determined by disk diffusion tests according to the guidelines of the Clinical and Laboratory Standards Institute.

Results: A total of 606 isolates were recovered from respiratory (70.

The effect of cup versus alligator forceps on the results of transbronchial lung biopsy.

Background: Transbronchial lung biopsy (TBLB) is a routine diagnostic procedure for pulmonary diseases and is performed by using either the alligator or cup forceps. The purpose of this study was to compare the role of the type of forceps in the quality and complications of TBLB.

Methods: This was a prospective, observational, double-blinded study.

Prognostic values of proliferative markers ki-67 and repp86 in breast cancer.

Background: Breast cancer is the leading cause of carcinoma death in women. Proper treatment depends on the consideration of molecular biology status of tumor cells, which may determine the patient's treatment and prognosis. To determine the prognostic models for this disease, we evaluated the role of cell proliferation-related antigens including ki-67 (a nuclear antigen, expressed in G1, G2, and M phases of cell cycle) and repp86 (an 86-kDa nuclear protein expressed in S, G2, and M phases of cell cycle) for detection of biologic behavior of breast cancer.
