Background & Aim : Symptoms associated with acute discomfort, e.g., headache eye, nose, or throat irritation dry and itchy skin, which are known as Sick Building Syndrome (SBS) are well reported amongst people who work in hospital environment especially in the X- ray department. The aim of this study was to determine the prevalence of the symptoms and to identify work related factors in hospital environment.

Materials and Methods : A questionnaire survey has been done from 219 hospital personnel who worked in the university hospitals (medical X-ray technologists, physiotherapists and office staff) as the exposed group and 219 personnel of the same occupations from private health care units and offices as the control group about if they experienced any of the mentioned symptoms in the last eight weeks. A total of 215 and 216 the questionnaire were accepted from each group respectively and included in analyses.

Results: From data provided by this work, 6 symptoms (headache, sorethroat, sinusitis, dermatitis,nasalaids and sore eyes)  have significant relationship between exposed and control groups. One symptom (catarrh) had significant difference among physiotherapists (P< 0.05), but with no significant difference between hospital and non-hospital environment. In addition, there was a relationship between incidence of dermatitis and history of skin allergy (P< 0.05).

Conclusion: The results from this preliminary work are similar with the studies, which have been done by others. These results also suggest that there is a link between incidence of SBS and hospital based chemical agents.

Background and Aim: Excessive Bleeding continues to play a key role and an important cause of morbidity and mortality after cardiopulmonary bypass (CPB). The goal of this study was to determine the differences in bleeding and transfusion between OPCAB and on -pump CABG patients.

Materials and Methods: In a randomized, double blinded prospective study 300 patient's undergoing coronary revascularization surgery were enrolled, 150 CABG patients were compared with 150 OPCAB patients. The patients were assessed during the first 72 hours to determine the postoperative side effects. The 2 groups were compared using the chi-square test or fisher's exact test and the rank sum test.

Results: CABG patients received more intraoperative red blood cells (P<0.0001), more albumin and more fresh- frozen plasma (P<0.0001). Postoperatively, CABG patients were more likely to receive more platelets (29.3% ν 70.7 %, P<0.007). During the operative and the initial 4-hour postoperative period OPCAB patients exhibited greater blood loss (P<0.0001) however, at 12,24and 72 hours postoperatively, CABG patients exhibited greater blood loss. There were4 death in CABG patients (P<0.05)

Conclusion: Despite not reversing the heparin at the end of the OPCAB surgery, OPCAB surgery was associated with an overall reduction in platelets, fresh- frozen plasma, Albumin and transfusion requirements.
