Detection of chemical warfare agent related phenylarsenic compounds and multibiomarker responses in cod (Gadus morhua) from munition dumpsites.

Recently, sea-dumped chemical weapons (CWs) containing toxic chemical warfare agents (CWAs) have raised international attention. It is well known that CWAs are leaking from corroded munitions causing a risk to the surrounding marine environment, while the impact on marine biota is still unknown. In this study, cod (Gadus morhua) was used as a model species to study the possible bioaccumulation of phenylarsenic CWAs and their negative effects at multiple levels of biological organization on fish living in the vicinity of a major CWs dumpsite in the Bornholm Basin in the Baltic Sea.

Rotavirus gastroenteritis in Finland: burden of disease and epidemiological features.

The burden of disease attributable to childhood rotavirus infection in Finland was assessed from data on hospital admissions for acute gastroenteritis and from reported virological diagnoses of rotavirus from 1985 to 1995. The mean number of hospitalizations (3584 annually in children under 5 y of age) corresponded to approximately 5.6% of the birth cohort.

Management of acute diarrhoea with low osmolarity oral rehydration solutions and Lactobacillus strain GG.

Two hypotonic oral rehydration solutions with osmolarities of 224 mosmol/l (Na+ 60 mmol/l, glucose 84 mmol/l) and 204 mosmol/l (Na+ 60 mmol/l, glucose 64 mmol/l), respectively, and oral treatment with Lactobacillus GG were evaluated in a double blind trial in children aged 6-36 months hospitalised for acute diarrhoea. Early administration of Lactobacillus GG at the start of oral rehydration resulted in the shortest duration of diarrhoea, best weight gain, and fastest correction of acidosis. A reduced osmolarity oral rehydration solution (224 mosmol/l) combined with early administration of Lactobacillus GG is an effective treatment for acute diarrhoea in young children; further reduction of osmolarity may not be beneficial.

Community-based survey of paediatric diarrhoeal morbidity and home treatment practices in Finland.

To determine total diarrhoeal morbidity and current home case management practices, a recall study was conducted among 345 mothers whose 406 children under 5 y of age had had diarrhoea in the past 4 months. The seasonally adjusted annual diarrhoea incidence rate was 0.48 episodes/child/y.

Randomised double blind study of hypotonic oral rehydration solution in diarrhoea.

A hypotonic (osmolality 224 mmol/l, sodium 60 mmol/l) oral rehydration solution (ORS) was compared with an isotonic high glucose ORS (osmolality 304 mmol/l, sodium 60 mmol/l) in children with acute diarrhoea in a randomised double blind study. The stool output and hence the mean consumption of ORS for maintenance hydration was less (p = 0.036) in patients receiving hypotonic (69 ml/kg) than isotonic (97 ml/kg) ORS.
