FirstAid knowledge among industry workers in Greece.

Occupational accidents cause serious consequences. Providing first aid (FA) in the workplace can reverse unpleasant results. Aim of our study was to evaluate the knowledge on FA of industry workers through a questionnaire. Our sample constituted of 236 workers, 40 (Group A) were trained on FA by a team of doctors authorised by the Hellenic National Centre of Emergency Help, while 196 had never have a formal training on FA (Group B). In Group A the mean value of correct answers (performance score) was higher than Group B (62.7 and 50.4 respectively), while the total sample of workers ranged from 21.1 to 84.2. Group A replied correctly about normal values (NVs) of pulse, arterial blood pressure (BP) and breaths at 67.5%, 35% and 47.5% respectively. Group B replied at 32.8%, 18.4% and 30.6% on the corresponding NVs. In Group A, 95% answered properly about the definition of Cardiopulmonary Rehabilitation (CPR) but only 25% were acquaint with the necessary number of chest compressions and 32.5% with the number of necessary mouth-to-mouth ventilations to practice in case of CPR. In Group B, the corresponding percentages were 72.4%, 26% and 36.7%. Only 5% from Group A and 1% from Group B answer correctly and simultaneously about estimation of vital signs and CPR practice. In conclusion, the vast majority of workers are unable to provide efficient FA as long as they can't estimate vital signs and provide satisfactory CPR.

Prognostic value of serum tumor markers in patients with lung cancer.

BACKGROUND: The role of tumor markers in the diagnosis and prognosis of lung cancer is under investigation. OBJECTIVES: The aim of this study was to investigate the diagnostic and prognostic significance of pre-therapeutic levels of various serum tumor markers, CYFRA 21-1, neuron-specific enolase (NSE), tissue polypeptide antigen (TPA), carcinoembryonic antigen (CEA), CA 125 and squamous cell carcinoma antigen (SCCAg), in patients with lung cancer. METHODS: We studied 102 consecutive patients (mean age 65.2 +/- 11 years) with newly diagnosed lung cancer (96 males, 94%, with a mean age of 66.3 +/-10.5 years). All patients had a 5-year follow-up. Measurements of the serum tumor markers were performed on initial diagnosis. RESULTS: Eighty-four patients (82%) had non-small-cell lung cancer (NSCLC) and 18 (18%) small-cell lung cancer (SCLC). From the 84 patients with NSCLC, 34 patients (33%) had squamous-cell lung cancer, 23 (22%) adenocarcinoma and 23 (22%) large-cell carcinomas. The overall median survival was 8.5 months. All SCLC patients had extensive disease with a median survival of 10.1 months and NSCLC patients of 8.4 months. Significant differences in the mean values of NSE and CYFRA 21-1 were observed between SCLC and NSCLC. In NSCLC, CYFRA 21-1, TPA, CA 125 and SCCAg serum levels were related to the stage of the disease at diagnosis, and CYFRA 21-1, NSE, TPA and CA-125 were related to a poor outcome. None of the above tumor markers was related to survival in the SCLC group. CONCLUSION: CYFRA 21-1 and NSE may help to differentiate cell types in lung cancer patients. Also, CYFRA 21-1 with TPA and CA 125 may provide useful information regarding the staging of the disease at diagnosis and the prognosis of patients with NSCLC.
