[Etiology, clinical manifestations, and epidemiology in community-acquired respiratory infection in children in the Khabarovsk region]. / Etiologicheskaia kharakteristika, klinika i épidemiologiia gruppovogo zabolevaniia respiratornoi infektsiei u detei Khabarovskogo kraia.

Clinico-epidemiological analysis and etiological verification of the outbreak of respiratory infection among school children in a rural district of the Khabarovsk territory, registered in spring 1997, were made. According to clinical signs, one-third of the patients had whooping cough, while the rest of the children exhibited the signs of respiratory infection with the symptoms of longering bronchitis. A half of the children had not been vaccinated against whooping cough, as they had been given injections of adsorbed DT vaccine with reduced antigen content. Etiologically, the diagnosis of whooping cough was confirmed in 57% of the patients with 47.4% of them having Bordetella pertussis monoinfection and 52.6% having mixed infection, mainly in combination with chlamydiosis. Whooping cough took an abnormal course under these circumstances. Treatment with erythromycin produced a good effect.

[Prenatal diagnosis of cytomegalovirus infection]. / Prenatal'naia diagnostika tsitomegalovirusnoi infektsii.

Prognostic value of markers of cytomegalovirus infection (CMV) in pregnant women for the neonatal status was assessed. Detection of such markers as antiCMV IgM and CMV DNA in cervical secretion by DNA dot-spot hybridization in women with a complicated course of pregnancy indicates a 5.7% risk of delivery of children with stable symptoms. Studies of antibodies to pre-early proteins (IE CMV) showed that antiCMV IgG to IE are more incident in pregnant women than antiCMV IgM; moreover, antiCMV IgG to IE but not antiCMV IgM are detected in umbilical blood. The results of detection of antiCMV IgG and IgM to IE correlated with the clinical characteristics of newborns.
