[The immunoglobulin content in the saliva of children living under different radioecological conditions]. / Soderzhanie immunoglobulinov v sliune detei, prozhivaiushchikh v razlichnykh radioékologicheskikh usloviiakh.

Salivary specimens of 80 children aged 8-14 years from the Stolin District and of 34 children of the city of Minsk are examined by radial immunodiffusion in gel and by enzyme immunoassay. Residents of a region contaminated with radionuclides (soil contamination with 137Cs 185-555 kBq/m2) develop an imbalance in the production and secretion of specific salivary antibodies: the production of IgM in early periods of immune response is suppressed and the level of IgE is increased.

[Ways to improve the caries resistance of the temporary teeth by using fluoridated salt]. / Puti povysheniia kariesrezistentnosti vremennykh zubov pri ispol'zovanii ftorirovannoi soli.

The content of calcium and phosphorus is decreased and that of fluorine increased in the oral fluid of children whose diet includes fluorinated salt, and the levels of calcium and phosphorus in their dental enamel are increased in comparison with children using common table salt. Three-year consumption of fluorinated salt resulted in a decrease of calcium release and increase of phosphorus release into acid biopsy.

[An epidemiological study of herpetic viral infections in the Republic of Byelarus]. / Izuchenie épidemiologii gerpeticheskikh virusnykh infektsii v Respublike Belarus'.

Studies on the epidemiology of infections caused by Herpes simplex virus, cytomegalovirus and Epstein-Barr virus in different age groups of the population of the Republic of Belarus, carried out over the period of many years, are summarized. The frequency of clinical manifestations of different forms of herpetic viral pathology in newborns, children and adults in different regions of the republic was studied. More frequent cases of the most severe clinical forms of herpetic viral infections (encephalitides, generalized infection) were noted in persons having immunodeficient states of different etiology, as well as among the population residing on the territory with unfavorable radiation conditions as a consequence of the catastrophe in the Chernobyl nuclear electric power station. For further study of the specific features of the epidemiology of herpetic obligatory registration of all cases of herpetic viral infections, starting from January 1, 1996, was introduced.

[The assessment of the stomatological status of children living in radionuclide-contaminated areas]. / Otsenka stomatologicheskogo statusa detei, prozhivaiushchikh na zagriaznennykh radionuklidami territoriiakh.

Dental status of 1051 children aged 3 to 13 living at Byelorussian territories polluted by radionuclides (Gomel and Mogilev districts) was examined in 1993-1994. Examinations revealed high incidence of caries, poor oral hygiene, high incidence of various pathological shifts in the buccal mucosa and red lips. The temperature and nonspecific resistance of the mucosa were reduced. Changes of the buccal mucosa were more expressed in younger children.

[The clinico-laboratory diagnosis of herpetic stomatitis in newborn infants]. / Kliniko-laboratornaia diagnostika gerpeticheskogo stomatita u novorozhdennykh detei.

A clinical picture of herpetic stomatitis was studied in 173 newborns, 122 of these preterm and 51 full-term ones, aged 2 to 43 days. Herpesvirus origin of the disease was proved in 68 out of 77 examinees with stomatitis (88.31 +/- 3.66%) by virological and immunofluorescent methods. The authors conclude that herpetic stomatitis in newborns is usually a result of ante- and perinatal infection, with intrauterine infection occurring in 37.57 +/- 3.68% cases.

[The clinical manifestations of herpetic stomatitis in children with acute lymphoblastic leukemia]. / Klinicheskie proiavleniia gerpeticheskogo stomatita u detei s ostrym limfoblastnym leikozom.

Clinical (n = 137) and virological (n = 50) analysis of the course of herpetic stomatitis in children with acute lymphoblastic leukemia was carried out. 97.8 +/- 1.4% of cases were relapses of a chronic herpetic infection, 73.8 +/- 3.7% of cases ran a medium severe or severe course. Herpetic stomatitis in children suffering from acute lymphoblastic leukemia was characterized by the following features: 1) a high risk of infection generalization; 2) progressive necrosis of tissues in a state of leukopenia; 3) infiltration at the site of necrosis; 4) tissue anemia; and 5) risk of hemorrhage from necrotic sites.

[Experience in preventing dental caries in the children of a city with a low fluorine content in its water]. / Opyt profilaktiki kariesa zubov u detei goroda s nizkim soderzhaniem ftora v vode.

Examinations of the dental status of 12-year-old children of the same schools of the town of Baranovichi in various years of two decades, from 1970 to 1990, showed an increase in the incidence and intensity of dental caries up to the year 1986. After a program of caries prevention was introduced in 1990, these parameters reduced. Local and systemic prophylactic means were tested and introduced in a complex of prophylactic measures. The best prophylactic effect was attained in children aged 9 administered sodium fluoride tablets since the age of 2 in comparison with the children administered such tablets since the age of 6. Efficacy of fluorine varnish and sealing of fissures on permanent molars with vitacryl was assessed.

[A preliminary analysis of oral morbidity in the children of Byelarus after the accident at the Chernobyl Atomic Electric Power Station]. / Predvaritel'nyi analiz stomatologicheskoi zabolevaemosti detei Belorussii posle avarii na Chernobyl'skoi AES.

Presents the data of analysis of medical files of therapeutic institutions, of questionnaires distributed among dentists, and the results of examinations of 883 children aged 3 to 6, living in 19 towns of Byelorussia. The incidence and clinical picture of a number of dental diseases were found changed in the children living in the regions contaminated with radionuclides, as well as the general well-being of these children.

[The status and functional characteristics of the organs of the oral cavity in children with chronic gastroduodenitis]. / Sostoianie i funktsional'naia kharakteristika organov polosti rta u detei s khronicheskim gastroduodenitom.

The status and functional characteristics of the oral cavity organs were studied in 85 children aged 7 to 12 with chronic gastroduodenitis with various gastric acid production and in 32 age-matched healthy children. Under study were mixed saliva pH values, oral mucosa temperature, Iakovets and Iasinovskii's tests, nonspecific resistance of the oral mucosa, that were examined over the course of hospital treatment. The findings evidence a higher dissemination and intensity of caries, a worse status of the oral cavity, and a higher incidence of periodontitis in the children suffering from gastroduodenitis as against the reference group. The patients' salivary pH values were found changed, oral mucosa temperature and defense potential reduced, oral mucosa saturation with ascorbic acid insufficient, and leukocyte migration into the oral cavity increased.

[The clinico-experimental validation of the use of low-intensity laser radiation for the treatment of exacerbated recurrent herpetic stomatitis in children]. / Kliniko-éksperimental'noe obosnovanie primeneniia nizkointensivnogo lazernogo izlucheniia dlia lecheniia obostreniia retsidiviruiushchego gerpeticheskogo stomatita u detei.

Experimental data are presented, validating the use of low-intensity laser irradiation at a wave length of 633 nm for the treatment of chronic recurrent herpetic stomatitis. Clinical trials were carried out in 167 children. Laser exposure with the optimal stimulating parameters was found to be an effective means for the treatment of children suffering from this condition.

[The clinical and pathogenetic characteristics of acute herpetic stomatitis in children belonging to a group at risk for the conversion of the disease into a chronic form]. / Osobennosti kliniki i patogeneza ostrogo gerpeticheskogo stomatita u detei, otnosiashchikhsia k gruppe riska perekhoda zabolevaniia v khronicheskuiu formu.

Two groups of children suffering from acute herpetic stomatitis were under study. 214 patients were referred to a group at risk of developing a chronic form of the condition on the basis of mathematical prediction. The immunofluorescent antibody technique was used to detect herpes simplex virus antigen in the peripheral blood leukocytes of healthy children and patients. The studies have shown inadequate humoral and local immunologic defense in the children referred to the risk group; herpes simplex antigen was more often detectable in their blood leukocytes than in the reference group.

[Use of an immunoglobulin with targeted action for the prevention and treatment of recurrent herpetic stomatitis in children]. / Primenenie immunoglobulina napravlennogo deistviia dlia profilaktiki i lecheniia retsidiviruiushchego gerpeticheskogo stomatita u detei.

The results of parenteral (2 to 3 injections of 1.5 to 3 ml once on 3-rd to 4-th day) application of the prepared immunoglobulin with the titer of antiherpetic antibodies of 1:512 to 1:1024 in combined treatment of 2 groups of patients are summarized. In 34 children aged 2 to 12 years recurrent herpetic stomatitis was at its exacerbation. In 27 patients aged 1 to 3 an acute (primary) herpetic stomatitis was present and the group was considered, on grounds of the originally designed prognostic system, as being at high risk of transition into the chronic frequently exacerbating form of the disease. Positive immediate anti-recidive and preventive effect was obtained and confirmed in 12 to 24 months' follow-up.
