The entry of food into the trachea causes severe obstructive and ventilatory disorders in infants. Surgical treatment of developmental anomalies includes open thoracic or transsternal access, which is traumatic, often complicated by pleurisy and mediastinitis in the postoperative period and long-term musculoskeletal deformities. Purpose. To demonstrate the effectiveness of minimally invasive surgery in the correction of this defect. Fibro-tracheo-bronchoscopy confirmed an isolated tracheoesophageal fistula in a 2-month-old child. Thoracoscopic intervention using 3 ports was chosen and performed as a surgical method of treatment. A large tracheoesophageal fistula, up to 10 mm, was found. The tracheal end of the fistula was sutured with 2 ligatures, tied and cut off. The defect in the wall of the esophagus was hermetically sutured. The postoperative period proceeded without complications. Enteral nutrition through the nipple started on the 10th day. Control examination after 1 and 6 months: the child has no anxiety; psychomotor development corresponds to age, on esophagoscopy the esophagus is freely passable, constrictions and defects were revealed . Conclusion. The high resolution and ergonomics of modern endoscopic equipment made it possible to visualize the malformation in an infant in detail, to separate pathological communication with minimal trauma and to avoid early and long-term complications.","PeriodicalId":21550,"journal":{"name":"Rossiyskiy Vestnik Perinatologii i Pediatrii (Russian Bulletin of Perinatology and Pediatrics)","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89434469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods. 121 adolescents received various preparations containing pertussis, diphtheria and tetanus as revaccination. Results. The use of the pertussis component in preparations for revaccination of adolescents, despite the fact that they initially have a certain level of seroprotection, is not accompanied by a significant increase in specific antibody titers.

To present a case of lingual ectopia of the thyroid gland in a child with an incidentally diagnosed formation of the root of the tongue based on primary ultrasound diagnosis. Material and methods. A 7-year-old boy without clinical signs of hypothyroidism during a routine examination revealed a voluminous asymptomatic formation of the root of the tongue. Results. Along the midline at the root of the tongue there is a rounded, non-displaced, painless formation about 20 mm in diameter. Regional lymph nodes are not enlarged.

There is subclinical hypothyroidism with a TSH level of 12.8 mсME/mL (normal 0.6–4.84). The presence of ectopia was confirmed by scintigraphy with Technetium-99m pertechnetate. Normal TSH level of 3.37 mcME/mL and a reduction in the volume of ectopic thyroid tissue from 3.3 mL to 2.13 ml revealed 3 months after levothyroxine therapy at a dose of 50 mcg/day. Conclusion. Ultrasound exam with Doppler mapping is mandatory and allows not only to identify ectopic tissue, but also to identify the absence of thyroid in a typical anatomical area on the neck.

There is no comparative analysis of data on the taxonomic diversity of the intestinal microbiota in chronic liver diseases in children. Purpose. To investigate the taxonomic diversity of the intestinal microbiota in children with chronic liver diseases compared with healthy patients, to identify differences in bacterial diversity in autoimmune and non-autoimmune liver diseases, as well as the impact of immunosuppressive therapy on the intestinal microbiota. Material and methods. A metagenomic analysis of the gut microbiota of 24 children with chronic liver diseases (mean age 10,3 ± 4,7 years) was carried out with the identification of the V3–V4 region of the 16S rRNA gene. The group included 18 children with autoimmune liver diseases and 6 children with non-autoimmune liver diseases. The control group consisted of fecal samples of 34 apparently healthy children. Results. When comparing fecal samples of children with autoimmune liver diseases with samples of healthy children, the taxa of Bacteroides dorei, Collinsella aerofaciens, Ruminococcus caffidurs prevailed, and for children of the control group — Neisseria flavescens. When comparing samples of patients with non-autoimmune liver diseases and the control group, it was found that the taxa Bacteroides fragilis, Klebsiella pneumoniae, Bifidobacterium longum prevailed in healthy children. When comparing fecal samples from children with autoimmune and non-autoimmune liver diseases, it was found that Veillonella dispar, Cloacibacillus porcorum, Veillonella parvula, Prevotella histicola and Bacteroides eggerthii taxa dominate in patients with non-autoimmune diseases. No dominant taxa of the gut microbiota were found in children with autoimmune liver diseases. It has been established that the taxa Veillonella dispar, Faecalibacterium prausnitzii, Roseburia inulinivorans, Bacteroides xylanisolvens and Alistipes obesi prevail in patients receiving immunosuppressive therapy, and the taxa Phascolarctobacterium succinatutens, Bacteroides ovatus, Solobacterium mooreis and Holdemanella massilien prevail in patients not receiving immunosuppressive therapy. Conclusion. A recent study of the gut microbiota in children with chronic liver disease shows differences in the imbalance of the gut microbiota compared to the results obtained in adults. The gut microbiota model is capable of distinguishing autoimmune liver diseases from non-autoimmune diseases. Immunosuppressive therapy is accompanied by the dominance of taxa that reduce the production of short-chain fatty acids.","PeriodicalId":21550,"journal":{"name":"Rossiyskiy Vestnik Perinatologii i Pediatrii (Russian Bulletin of Perinatology and Pediatrics)","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89102527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the top places in the structure of morbidity in late preterm is occupied by respiratory disorders. Quite often there is transient tachypnea, respiratory distress syndrome of the newborn, pulmonary hypertension, and congenital pneumonia. Currently, there are various approaches to prevention, treatment, and diagnosis of respiratory disorders in late preterm children. Until now, the issue of the advisability of prenatal prevention of respiratory distress syndrome with corticosteroids after the 34th week of gestation has not been resolved. Non-invasive methods of respiratory support are more popular along with minimally invasive administration of surfactant preparations when indicated. The trend towards an annual increase in late preterm births determines the need to improve the methods of their nursing.

To reveal the features of postural control development in infants of the first year of life with the consequences of perinatal lesions of the central nervous system in the form of impaired motor development, born at different gestational ages. Material and methods. We examined 120 infants of the first year of life with impaired motor development and 16 infants without neurological pathology. Infants with impaired motor development were divided into 4 subgroups: 1 (n = 30) — full-term, 2 (n = 30) — very preterm, 3 (n = 30) — moderately preterm, 4 (n = 30) — late premature children depending on their gestational age at birth. The examination was conducted at 3–4 months of calendar age in full-term and corrected in premature infants and included an assessment of the neurological status, a clinical assessment of postural control, and computer stabilometry. Results. Violation of postural control was found in infants of the first year of life with the consequences of perinatal lesions of the central nervous system in the form of impaired motor development, born at different gestational ages. These postural disorders may be associated with changes in muscle tone and impaired sensorimotor integration. Conclusion. Further research will enable the development of objective criteria for diagnosing postural disorders in infants of the first year of life, depending on the gestational age at birth.
