Nosocomial pneumonia is associated with increases in health care costs, morbidity and mortality. Data from our study in Bach Mai Hospital in 90 patients admitted to intensive care units from 1999 to 2001 indicate that, approximately 86% of patients got nosocomial infections. Gram(-) organisms were predominant (76%) with P.aeruginosa 57.3%; S.aureus 10.7%; Enterobacter 7.7%; Acinetobacter 6.8%. Almost these gram(-) becterial isolates were sensitive to imipenem (95.7%) and amikacin (87.8%).

Thibeault C. Special Committee Report : Cabin Air Quality Aviat Space Environ Med 1997 ;68 : 80-2. Cabin Air Quality has generated considerable public and workers' concern and controversy in the last few years. To clarify the situation, AsMA requested the Passenger Health Subcommittee of the Air Transport Medicine Committee to review the situation and prepare a position statement. After identifying the various sources of confusion, we review the scientifically accepted facts In the different elements involved in Cabin Air Quality : pressurization, ventilation, contaminants, humidity and temperature. At the same time, we identify areas that need more research and make recommendations accordingly.

In this clinical trial, 60 patients who suffered from AFB positive infiltrative pulmonary tuberculosis and being cured in consolidative chemotherapy in specialized hospitals, the age from 20 to 59 years old, not sexes distinguish. Kinds of ventilation: 93.33% of patients suffered from restrictive ventilation and the rate of mix ventilation was 6.67%, no participant was obstructive ventilation. Mean values of VC was 53.93%5.97; of Tiffeneau index 80.756.63%

Study on 75 subjects included 54 silicatosis patients (51 males, 3 females, mean age 43.9±9.8) working in seagoing vessel repairing and new building branch. Control group included 21 people (19 males, 2 females). All of these subjects were working in a labor environment, in which SiO2 dust level exceeded allowable limit from 4 to 21 folds with mean exposed times 16.8±5.2 years. The results showed that: 54 silicatosis patients had remarkable symptoms such as chest pain (83.3%), exercise dyspnea (74.1%), decreased alveolus soughing (59.3%). There were 75.9% in all of patients had pulmonary ventilation disorder, in which mainly were limited pulmonary ventilation disorder (53.7%).

Study on 33 asthma patients and identifying maximum expiring volume per second and medium flow between expiring stage of living volume from 25% to 75% in asthma patients without severe stuffy treated at Bach Mai hospital in 2000. The results: there was no difference of sex in asthma. 24% of patients with childhood asthma; 0.6% of them with asthma over 20 years and 30% of them with asthma from 10 to 20 years. After treatment, medium expiring gaz flow at the middle of expiring stage at 25% to 75% of living volume decreased down 50.8% compared with theory value. 48% of patient with mixture ventilation disorder. 40% of patients with obstructed ventilation disorder, 24% of patients with pheriperal obstructed ventilation disorder
