Application of informatics in the work of a pathologist: guidelines for learning how to create and use a digital archive of gross images
Khramtsov A.I., Nasyrov R.A., Khramtsova G.F.
Abstract

Pathology informatics has been developing as a response to a large amount of diagnostically relevant morphological information and attempt to the best store and use it. The main components of pathology informatics include digital images of histological slides and gross photographs, telepathology, and electronic data collection. Photo documentation of gross specimens is an integral part for efficient work of a pathologist. Currently, many grossing stations are equipped with continuously recording video cameras. A logical and detailed description of the macroscopic specimens, supported by properly obtained digital photographs, should be the standard of a modern pathology report. However, with the increasing workload of the pathologists, they have less and less time to take gross photographs. That is why, in our opinion, it is important to ask questions such as: what is necessary to photograph, how to take a photo of the gross specimen, and in which order? There are only a few publications on this topic in both domestic and foreign literature. This paper attempts to summarize the literary data on this topic, based on which a list of medical use cases that require a mandatory photo documentation has been created. Practical recommendations have been developed and are outlined for gross photographs. In the context of widespread use of digital photography as a resource for deep learning of neural networks and digital analysis, this article will be useful not only for postgraduate education of pathologists, but also for physicians of other specialties.

Original studies

Influence of pain on the development in preterm infants
Andreyev A.V., Kharlamova N.V., Mezhinskij S.S., Shilova N.A.
Abstract

Introduction. The influence of uncontrolled exposure to pain in newborns in the first days of life on the long-term consequences for both the brain and the development of the nervous system as a whole is of interest.

The aim of the study was to assess the intensity of pain in preterm infants who need respiratory care in the early neonatal period and to determine its impact on the development of the child by the end of the first month of life.

Materials and methods. From December 2018 to December 2019, 92 preterm infants requiring respiratory support in the early neonatal period were examined. Pain intensity was assessed on the EDIN6 scale, and neuro-muscular maturity was assessed on the J. Ballard scale. The preterm infants were divided into 2 groups: Group I – 34 children who underwent invasive ventilation (body weight 1120 [865; 1390] g, gestational age 29 [26; 31] weeks); group II – 58 newborns who used non-invasive respiratory therapy (CPAP) (body weight 1160 [875; 1400] g, gestational age 29 [28; 31] weeks). Group I newborns had a lower Apgar score at 5 minutes (p = 0.001) and a higher Silverman score (p = 0.001).

Results and discussions. In all newborns, the maximum pain intensity score on the EDIN6 scale was registered on the 3rd day of life: in group I, it was 9, and in group II – points (p = 0.041), which corresponds to moderate pain. Group I children underwent more manipulations (20.8 ± 2.14 vs 17.7 ± 2.05; p = 0.016). An increase in the average airway pressure of ≥10 cm H2O in group I children and ≥6.5 cm H2O in group II patients is accompanied by an increase in the intensity of pain to severe and moderate, respectively. In both groups of children, an inverse correlation was found between the number of manipulations, head circumference (R = –0.64; p = 0.004) and the J. Ballard score on the 28th day of life (R = –0.57; p = 0.008). The number of painful manipulations in the early neonatal period, exceeding 21 procedures per day, increases the risk of delayed child development by more than 3.5 (p = 0.009; OR = 3.68; CI = 1.12–8.36).

Conclusion. The number of manipulations performed and the value of the average airway pressure are the main factors affecting the intensity of pain in preterm infants and determining their development in the neonatal period.

Changes of morphofunctional state of cardiovascular system in adolescents with metabolic syndrome manifestations
Gonchar N.V., Аvakyan А.А., Chuprova S.N., Slizovskiy N.V.
Abstract

The results of investigation of features of morphofunctional state of cardiovascular system in adolescents with manifestations of metabolic syndrome depending on presence of hyperuricemia are presented. In the cardiorheumatology department of the hospital, 34 adolescent patients were observed. Criteria for inclusion in the study: the presence of increased blood pressure levels, increased body mass index values. Depending on serum uric acid levels, patients were divided into two groups: group 1 – patients without hyperuricemia (n = 18) and group 2 – patients with hyperuricemia (n = 16). Functional diagnostic methods were used: standard 12-channel electrocardiography, transtoral echocardiography, daily Holter monitoring. The main attention was paid to the study of the parameters of the left ventricle. Student’s t-test was used to determine the significance of the differences, the results at p < 0.05 were considered reliable. It was established that adolescents with hyperuricemia were more often diagnosed with primary and secondary arterial hypertension, less often with labile arterial hypertension and autonomic dysfunction syndrome by hypertensive type, and adolescents without hyperuricemia were equally often diagnosed with primary arterial hypertension and labile arterial hypertension, autonomic dysfunction syndrome by hypertensive type. Signs of left ventricular remodeling according to echocardiography were more often noted in boys without hyperuricemia (62.5% of cases) than in girls without hyperuricemia (10%; p < 0.01) and in boys with hyperuricemia (26.7%; p > 0,05). The findings indicated more significant changes in the morphofunctional state of the cardiovascular system in adolescents with hypertensive conditions and manifestations of metabolic syndrome without hyperuricemia, which requires further study.

Relationship between the parameters of the frontal cortex bioelectric activity and extraversion and neuroticism level
Smit N.Y., Aleksandrov M.V., Karelina N.R., Lytaev S.A., Marchenko E.V.
Abstract

The frontal lobes make a significant contribution to the formation of individual personality traits, in connection with which it is important to identify the links between the parameters of the bioelectric activity of the frontal cortex and the indicators of psychological tests. The aim of this work was to study the relationship between the indicators of extraversion and neuroticism of the subjects and the parameters of their EEG. For the first time, differences in these relationships were found at rest and during standard functional tests, without the use of additional specialized loads. The study involved healthy subjects of both sexes, average age 19.3 years; all subjects are right-handed. To identify the level of extraversion and neuroticism, the standard Eysenck test (option B) was used. The EEG was recorded using the bipolar derivation method. 19 electrodes were exposed in accordance with the international Jasper system 10–20%. EEG was recorded at rest with eyes closed and during functional tests: eye opening, hyperventilation, photostimulation. The correlation coefficients of the index and absolute power of the EEG with the level of extraversion and neuroticism were calculated both for the entire sample of subjects and for individual groups according to the level of extraversion and the level of neuroticism. For the entire sample of subjects, positive significant correlations of EEG power with the level of extraversion and negative – with the level of neuroticism were revealed. In the groups of subjects with high, medium and low levels of extraversion and neuroticism, the differences in correlation relationships with EEG parameters are more pronounced. In these groups, these differences are more often manifested when performing functional tests than at rest with closed eyes.

The research of motor development of premature infants in an outpatient-polyclinic service
Ivanov D.O., Suslova G.A., Surenkova I.N., Filippova V.N.
Abstract

The article is devoted to the research of the development of motor skills of premature babies on the background of medical rehabilitation in an outpatient-polyclinic and the determination of the age standard (scale) for the development of motor skills of premature babies. The research includes 137 premature babies with the gestational age from 26 to 37 weeks, birth weight from 800 to 2600 grams. The main group of the research consisted of 117 premature babies who had already took a part in the early and complex rehabilitation, the control group which consisted 20 children who were included in the research because of a history of prematurity and who applied to the rehabilitation department with already established disabilities (the health status of premature babies in the control group was studied retrospectively). Premature babies in the control group began medical rehabilitation after 6 or more months of life and did not receive it in full. The assessment of the motor skills of premature babies was carried out in dynamics on the monthly basis. Of the 117 premature babies of the main group 2.5% had motor disorders that led to disability, the premature babies of the control group reached disability in 100% of cases. The research of motor development of premature babies revealed that with a delay in applying for medical rehabilitation, even for one day, the integrated indicator of the relative deviation of actual skills development from the standard increases by 0.9%.

Basic principles of early intervention for children with hearing loss
Garbaruk E.S., Kozhevnikova E.V., Struzhkin M.L.
Abstract

Hearing loss is a common birth problem that can affect a baby’s ability to develop speech, language and social skills in lack of comprehensive early intervention. Early intervention occurring within the first 6 months has higher effectiveness for hearing impaired children. The introduction of universal newborn hearing screening programs allowed to identify hearing loss in the first months of life. That determines the need of immediate comprehensive early intervention for children identified with hearing loss. The main approaches of such intervention have been described in detail in the literature. However there are not well-developed, evidence-based, well-documented recommendations for family-centred early intervention for children who are deaf or hard of hearing. Similar problems are noted in many countries, that is why in 2012, within the framework of an international conference, specialists and parents of deaf and hard of hearing children developed a document (international consensus statement). The experts arrived at consensus on 10 principles guiding family-centred early intervention. These principles are presented in the article as well as a brief description of their implementation in various countries. The consensus statement has become an important document which is intended to provide a framework for professionals over the world. Knowledge of these principles allows specialists to apply evidence-based approaches working with children who are deaf of hard of hearing.

Obesity and functional bowel disorders in children
Pogodina A.V., Romanitsa A.I., Rychkova L.V.
Abstract

Obesity and functional bowel disorders (FBDs) are often observed in children and share common risk factors. However, the possible relationship between these conditions has begun to be studied recently and the results obtained are ambiguous. Therefore, it is important to summarize the literature on the relationship between obesity and FBDs in children and to discuss the possible pathophysiological mechanisms mediating this. The literature suggests that obesity and FBDs are likely associated conditions. A significant link between obesity and irritable bowel syndrome in children has been confirmed by all studies on this problem. There is also a many evidence that obesity in the pediatric cohort is associated with constipation. However, it should also be noted that there are few studies of this issue, they are heterogeneous in the composition of participants and the diagnostic criteria used, in most cases they are unadjusted for potential confounders. The link between obesity and FBDs may be mediated by diet, eating habits, and psychological factors. But the most promising direction in studying the association between these conditions may be studies of the gut microbiota, changes in which can contribute to impaired intestinal immune function, the development of chronic low-grade inflammation, increased intestinal permeability, impaired motility and visceral hypersensitivity. To date, there is insufficient data to confidently confirm the existence and nature of the relationship between obesity and FBDs in children, but research in this direction can provide important information for the development of approaches to treatment, prevention and early diagnosis of both groups of diseases.

Precocious puberty in girls: a clinical case of idiopathic central precocious puberty
Lagno O.V., Turkunova M.E., Bashnina E.B.
Abstract

Central precocious puberty occupies an important place in the practice of a pediatric endocrinologist. If the patient reveals signs of premature sexual development, the diagnostic search is aimed at eliminating the tumor origin of both false (peripheral) and gonadotropin-dependent, or central, precocious puberty, as well as gonadotropin-independent forms of premature sexual development. Oncological alertness is important in the work of not only a pediatric endocrinologist, but also a pediatrician. In the treatment of all non-tumor forms of central precocious puberty, drugs of the group of analogues of gonadotropin-releasing hormone are used, which allows to stop the progression of sexual development, reduce the rate of bone maturation and, thereby, increase the final growth of the child. The most common idiopathic variant of central precocious puberty. The article presents a clinical case of observing a patient with an idiopathic variant of central premature sexual development during therapy with a drug from the group of analogues of gonadotropin releasing hormone of prolonged action. The classical course of the idiopathic variant of central precocious puberty with typical diagnostic difficulties in the onset of the disease, good compensation against the background of therapy with a drug from the group of agonists of gonadotropin-releasing hormone and normal puberty 6–12 months after cancellation of the therapy is demonstrated. The latter is explained by the proven reversibility of the effects of this group of drugs. The description of this clinical case, in the authors’ opinion, should be of interest to doctors at the local pediatricians and pediatricians working in the medical care departments for children in educational institutions.

History of pediatric university

In memoriam of our colleagues and friends
Gorbunova V.N.
Abstract

The Department of General and Molecular Medical Genetics of St. Petersburg State Pediatric Medical University has existed for more than thirty years. Over these years, three outstanding scientists and clinical geneticists, our colleagues and members of the department, have passed away. Fundamental works of A.M. Polishchuk contributed to the study of radiation-induced chromosomal instability. One of the pioneers in the field of clinical cytogenetics in our country, A.M. Polishchuk was also at the origins of teaching genetics to future doctors. He was in the staff of the Department of Medical Genetics of St. Petersburg State Pediatric Medical University since its foundation in 1989, where his teaching experience was very appreciated. Having emigrated to Israel in the mid-1990s, A.M. Polishchuk continued his studies in laboratory genetics. The history of the development of genetics in Russia remained In the field of scientific interests of A.M. Polishchuk, until recent years. A.M. Polishchuk died in February 2020. Among the first members of the Department of Medical Genetics was also V.V. Krasilnikov. A student of the famous geneticist-neurologist E.A. Savelyeva-Vasilyeva, V.V. Krasilnikov became a prominent specialist in the field of clinical genetics, who spent more than three decades working at the Medical Genetic Center. An excellent diagnostician, he had a broad scientific outlook and deep knowledge in the study of microanomalies of development in hereditary pathology. After a long-lasting illness V.V. Krasilnikov died in 2012. V.G. Vakharlovsky was also a student of E.A. Savelyeva-Vasilyeva. The opus magnum of this outstanding clinician was the development of methods for pathogenetic therapy of the very grave hereditary diseases: Wilson–Konovalov disease and spinal muscular atrophy. Having joined the team of the Department of Medical Genetics of the St. Petersburg State Pediatric Medical University in the 2000s, he brought into the educational process the practice of visiting a boarding home for mentally-handicapped children, introduced regular case studies. In 2010, with the Vakharlovsky’s death our collective suffered the big loss.
