[Biochemical changes of red blood cells in children with cerebral palsy and other organic brain disorders].

One hundred and twenty-five children with cerebral palsy (n = 108) and organic CNS lesions (n = 17) have been studied. A control group included 30 children without any neurological lesions. Lipids and phospholipids spectra, Ca, Mg- and Na, K-ATPases, intensity of red blood cells lipid peroxidation and erythrocyte free magnesium content have been determined.

[Significance of congenital mixed viral infection in the pathogenesis of retinopathy of prematurity].

Forty-three infants aged 1-5 months with somatic and neurological diseases, including congenital, 18 of these with retrolental fibroplasia (RF) and 25 without RF were examined. Control group consisted of 36 age-matched infants. Based on identification of viral antigens in urine precipitate cells, mixed viral infection was diagnosed in 100% patients and 16.

[Chronic congenital Coxsackie virus infection in the etiology of allergic disease in children].

The authors prove the involvement of congenital Coxsackie virus infection in the etiology of allergic diseases in children: 1) indications of high risk of vertical transmission of viruses of this group from mothers with persistent infection to children are more incident in the history of mothers whose children develop allergies in comparison with healthy age-matched children (83 vs. 38.8%); 2) Coxsackie viruses are detected in sick children more often than in healthy ones (58.

[Study of vertical transmission of coxsackie group enteroviruses in the etiology of congenital immunodeficiencies].

Morphological and virological studies were carried out in 26 cases of perinatal and neonatal deaths in a group at a high risk of vertical transmission of Coxsackie viruses. Antigens of Coxsackie viruses A and B were identified in 73.1% of autopsy materials, including the thymus.

[The importance of the vertical transmission of enteroviruses in the epidemiology of congenital viral infections].

A total of 814 newborns were examined using a highly sensitive method of indication of viral antigens. A high incidence of congenital viral infection was revealed: 450 per 1000 live-born children. Enteroviral infections (mainly Coxsackie) ranked first in prevalence.

[The significance of a mixed congenital viral infection in human antenatal and perinatal pathology].

Examinations of 202 newborn babies for a representative group of viral infections by detection of viral antigens in cells of urine sediment and in the autopsy materials by indirect immunofluorescence permitted diagnosis of a congenital viral infection in 92% of patients with intrauterine and perinatal pathology; in 72.5% it was a mixed infection. In the patients the virus-virus associations were, as a rule, represented by enteroviruses of Coxsackie group and/or influenza A, B, and C viruses.

[An experimental model of the vertical transmission of the Coxsackie-group enteroviruses and its use in developing methods to prevent congenital coxsackievirus infection].

An experimental model of vertical transmission of Coxsackie group enteroviruses was developed in BALB/c mice the first generation of which was infected with Coxsackie A18 virus in the neonatal period. Persistence of the virus was demonstrated in all females of the first generation tested and in 90.9% to 100% of the animals of the next two generations.

[The significance of a congenital enterovirus infection in the pathogenesis of transient intrainfectious nephropathy and interstitial nephritis detected in children with influenza-like and acute respiratory diseases].

The paper presents the data confirming the hypothesis on the involvement of the congenital enteroviral infection in etiology of chronic nephropathy manifesting in children in the presence of influenza-like and acute respiratory infections diseases. 100 relevant children were examined. Family history indicated a high risk of enteroviruses inheritance from mothers who were chronic carriers in 19 out of 20 children with pyelonephritis or interstitial nephritis (95%), in 17 out of 23 children with transitory nephropathy (73.

[The immunomorphological characteristics of the appendix in a viral-bacterial lesion in children with appendicitis].

The characteristics of viral-bacterial lesion in the appendix of children with appendicitis are given by means of histologic, histochemical, immunomorphological and morphometric methods. Antigens of influenza viruses A, B, C, entero-, adeno- and paramyxoviruses were observed among which influenza C was found significantly more frequently (64.1%).

[The role of congenital Enterovirus infection in the pathogenesis of suppurative and inflammatory diseases in newborn infants].

Newborns with suppurative-inflammatory disease were found to be at high risk of intrauterine infection with Coxsackie enteroviruses from mothers with persistent enterovirus infection; in 54.9%, congenital Coxsackie virus infection was confirmed by virus antigen identification in the urine sediment cells and autopsy material. Coxsackie A viruses were identified in 68.

[A method for the assessment of adaptation possibilities of a child's body].

The authors suggest a new method for the assessment of the adaptation potentialities of the child's body according to the conjugated shift in the systolic arterial pressure and heart rate (in percent from normal) within the system of coordinates. The method provides an objective evaluation of the individual responses of the child to different actions, supplements an overall estimation of the health status, and makes it possible to identify the risk group children.

[The role of prenatal Coxsackievirus infection in the etiology of congenital heart defects in children].

Sixty-two children with congenital heart diseases and 100 normal children were examined, their age ranging from 5 days to 6 years. Indicators of intrauterine enterovirus infection risk were detected in 93.5% of children with congenital heart diseases and in just 21.

[Long-term persistence of coxsackieviruses in familial foci of infectious myocarditis patients].

Numerous examinations during 12-36 months of 16 children suffering from myocarditis and their 37 relatives revealed long-term persistence of Coxsackie A13/A18 viruses in the familial foci of infection in 13 cases. In addition, 9 families were found to have foci of Coxsackie B virus infection of which 2 were also persistent (Coxsackie B1 and B3) and 7 transitory. In 8 families, Coxsackie B viruses circulated simultaneously with Coxsackie A13/A18.

[Risk of intrauterine infection of the human fetus with Coxsackie viruses in pregnancy complicated by late toxicosis and pyelonephritis].

During virological examinations of 144 pregnant women including 85 women with complicated course of pregnancy Coxsackie A viruses were isolated from the blood or identified in the cells of urinary tracts in 60.3% of the cases of nephropathy, in 68.3% of the pregnant women with pyelonephritis, and in 8.

[Antibodies to viruses in children with diabetes mellitus].

Serological studies were carried out in the time course of insulin-dependent diabetes mellitus in 419 children, among whom paired sera from 66 were studied in the very beginning of diabetes mellitus. By seroconversion in 83% of the children early in the disease, different, frequently mixed virus infections were diagnosed: Coxsackie B2, B3, B4 (46%), rubella (41%), influenza A, B, C (38%), parainfluenza types 1-3 (35%), mumps (23%), adenovirus infection (18%), HB virus infection (4.5%).
