Saturation divers regularly inspect North Sea installations, working at depth for periods of 12-16 days. Diver's hand is a particular problem in saturation diving, and there is no effective protection or treatment available. This paper presents the occurrence of diver's hand and describes the disease in clinical and epidemiological terms. Three studies of(More)
OBJECTIVES Occupational saturation divers have various skin disorders, of which skin infections are the most serious and frequent. Pseudomonas aeruginosa is the microbe most often isolated from skin infections in divers. The purpose of the present work was (a) to report the occurrence of P aeruginosa in skin infections in operational saturation diving in(More)
INTRODUCTION Skin infections in saturation diving are caused by microbes that flourish in saturation environments. Improvements in the prevention of infections must therefore be based on environmental control and elimination. Furthermore, only a few genotypes seem to be responsible for the majority of infections in the Norwegian sector of the North Sea, and(More)
In this study, the authors sought to address the relationships between measured indoor environmental factors and nasal patency (i.e., minimum cross-sectional area) and volume and markers of nasal inflammation in nasal lavage fluid. Clinical data were obtained for 115 females who worked at 36 geriatric nursing departments. The indoor climates in the nursing(More)
BACKGROUND Little is known about the occurrence of Legionella pneumophila in water supply systems on board ships. Our aim was to study the occurrence of L. pneumophila in the water supply system on board Norwegian naval vessels as the basis for framing preventive strategies against Legionella infection. MATERIAL AND METHOD Water samples were collected(More)
BACKGROUND Occupational saturation divers suffer from various skin disorders, of which skin infections are the most serious and frequent. Pseudomonas aeruginosa is the microbe most often isolated. METHODS P. aeruginosa isolates from 292 skin infections in operational saturation divers and about 800 isolates from occupational saturation diving systems have(More)
Skin infection caused by Pseudomonas aeruginosa is the most frequent health problem associated with occupational saturation diving on the Norwegian continental shelf. In the course of 14-y surveillance of infection and environmental control in occupational offshore saturation diving systems, a collection of approximately 1000 P. aeruginosa isolates has been(More)
BACKGROUND Recurrent legionella outbreaks at one and the same location are common. We have identified a single Legionella pneumophila genotype associated with recurrent Legionella outbreaks over 6 years. METHODS Field emergency surveys following Legionella outbreaks were performed on a vessel in 2008, 2009 and 2013. Water samples from both the(More)
OBJECTIVE Skin and ear infections, primarily caused by Pseudomonas aeruginosa (P. aeruginosa), are recurrent problems for saturation divers, whereas infections caused by P. aeruginosa are seldom observed in healthy people outside saturation chambers. Cystic fibrosis (CF) patients suffer from pulmonary infections by P. aeruginosa, and it has been(More)
