[Season and age related structure of acute intestinal infections morbidity in the Russian Federation].

Aim: To study seasonal and age features of etiological structure of acute intestinal infections (AII) in the territory of the RF.

Material And Methods: A total of 7388 AII inpatients aged from 1 day to 90 years from 7 cities (Moscow, St-Petersburg, Nizhniy Novgorod, Chelyabinsk, Tyumen, Makhachkala and Khabarovsk) of the RF participated in a trial conducted from December 2001 to September 2006 The patients were examined with diagnostic tests based on polymerase chain reaction (PCR) for detection of rotaviruses of group A (RVA), noroviruses, astroviruses, adenoviruses, salmonella, termophilic campilobacteria, shigella and enteroinvasive Escherichia coli (EIEC).

Results: The above agents were detected in 72% children and 52% adults.

[Changes in the peripheral circulation of children with severe forms of acute intestinal infections].

Photoelectroplethysmography of the skin of the end phalanx of the right hand thumb was used in 100 children with grave forms of acute intestinal infections and in 31 healthy babies to study changes in peripheral circulation. The patients demonstrated the lowering of the skin blood content, in proportion to the degree of dehydration, as well as an increase of postcapillary resistance to the blood flow in the skin and subcutaneous fat, seen not only in the acute disease period but also in the stage of early convalescence.
