objective: infection control is one of the important aspects in dentistry. oral and maxillofacial surgery is one of the most sensitive fields in dentistry in which infection control is important a sterile surgical set is imperative. manufacturers only guarantee the sterility of the anesthetic not the sterility of its outer surface. they recommend alcohol to sterile the outer surface (especially...

Contamination of hospital surfaces by bacteria is increasingly recognized. We assessed commonly touched surfaces using contact plates and Petrifilms (3M, St. Paul, MN) and compared the results against proposed microbiology standards. Toilet door handles were the most heavily contaminated (7.97 ± 0.68 colony forming units [CFU]/cm(2)) and exceeded proposed standards on 74% of occasions. Petrifil...

OBJECTIVES Studies examining healthcare workers' exposure to antineoplastic drugs have focused on the drug preparation or drug administration areas. However, such an approach has probably underestimated the overall exposure risk as the drugs need to be delivered to the facility, transported internally and then disposed. The objective of this study is to determine whether drug contamination occu...

Finding a non-pathogenic surrogate aerosol that represents the deposition of typical bioaerosols in healthcare settings is beneficial from the perspective of hospital facility testing, general infection control and outbreak analysis. This study considers aerosolization of dilute aqueous lithium chloride (LiCl) and sodium chloride (NaCl) solutions as surrogate tracers capable of representing Sta...

Many healthcare workers are concerned about the risk of occupational exposures to hazardous drugs. The Japanese Society of Hospital Pharmacists (JSHP) revised the "Guidelines for the Handling of Antineoplastic Drugs in Hospitals", however, the precautions and awareness of handling drugs varied in institutions. We assessed the levels of environmental contaminations in our hospital and urinary ex...

BACKGROUND Nowadays, the bacterial contamination in the hospital environment is of particular concern because the hospital-acquired infections (HAIs), also known as nosocomial infections, are responsible for significant morbidity and mortality. This work evaluated the capability of Enterococcus hirae to form biofilm on different surfaces and the action of two biocides on the produced biofilms. ...

conclusions the frequency of nis in this hospital was lower in comparison with other worldwide studies. however, low incidence of health care-associated infections in our study may be due to under diagnosis and underreporting of such infections by health care staff. results the incidence of nis was low (i.e. < 2%). among 16936 admitted patients in this hospital, 174 patients (79 males and 95 fe...

objective(s): the nosocomial infections by aspergillus species are associated with constructions and increased dust loads in hospital indoors. our main object was to find the environmental sources of aspergillus species causing hospital acquired infections. materials and methods: the clinical and environmental samplings were performed during 18 months from spring 2010 to summer 2011 in imam edu...
