[Cognitive symptoms in an elderly patient--maintaining the functional capacity is always important].

In primary health care, elderly patients having problems in their ability to deal with information are increasingly encountered as a result of lessened institutional care and altered population structure. The most common causes of cognitive problems in the elderly include delusional disorder, various progressive memory diseases and delirium. Treatment of cognitive problems is multidisciplinary collaboration, and maintaining the functional capacity is important at all stages of the disease.

[General practice research in Finland].

Researchers within our largest specialty, general practice, are above all interested in the contents and quality of their own work, organizing the work and treatment practices. Clinical research is conducted to a limited extent only. Primary health care is being studied in the universities and research institutes in a multidisciplinary manner, but only a small proportion of the authors of peer-reviewed studies are working in community health centers.

Artificial radionuclides ⁹⁰Sr and ²⁴¹Am in the sediments of the Baltic Sea: total and spatial inventories and some temporal trends.

The Baltic Sea was contaminated by radioactivity following global nuclear fallout and later by the Chernobyl accident. Despite the decrease of radioactivity caused by radioactive decay, radionuclides have a prolonged residence time in the water of the Baltic Sea due to slow water exchange and relatively rapid sedimentation. Very little is known about the amounts or spatial differences of ⁹⁰Sr and ²⁴¹Am in the Baltic Sea sediments.

Spatial distibution and temporal accumulation of polychlorinated dibenzo-p-dioxins, dibenzofurans, and biphenyls in the Gulf of Finland.

Dated sediment cores and surface sediments were analyzed from the Gulf of Finland, a part of the Baltic Sea, to study the sources, levels, distribution, and total amounts of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs). The gulf was found to be severely polluted, with PCDD/F sum concentrations as high as 101000 ng/kg and 479 ng/kg WHO-TEQ in dry weight. The source of pollution was the former manufacturing and use of a chlorophenol based wood preservative along the Kymijoki River.
