Introduction. Currently, only a small number of countries have a stable iodine adequacy, about a third of the world’s population lives in areas with some iodine deficiency. Because children have an increased risk of adverse effects in response to iodine deficiency, it is important to assess the health of these children. Aim. To investigate the frequency of iodine deficiency in children from the iodine deficiency region. Methods. The research was conducted during expeditions to various geographical areas of Northern Bukovyna (Chernivtsi region, Ukraine). 1,973 school-age children were examined (measurement of anthropometric indicators, assessment of cognitive, physical and sexual development, ultrasonography of the thyroid gland (TG), ovaries and testicles, determination of hormonal status and iodine in urine). Results. Of 1,973 children, 53.7% (1060) had thyroid abnormalities. The frequency of goiter in the mountain zone – 59.8%. In 12.3% of children there was a tendency to increase of TSH. The median ioduria in children from mountainous areas corresponds to moderate iodine deficiency. Children from mountainous areas have various disorders: 38.5% disharmonious physical development, a third low intellectual development, disorders of the order of appearance and development of secondary sexual characteristics in the examined children. Conclusion. The results of the study show the negative impact of iodine deficiency on the body of children. It is necessary to continue monitoring of ioduria and children’s health and implement preventive measures.

Hormone Therapies

Displacing the physiological model that had held sway in 19th-century medical thinking, early 20th-century hormone research promoted an understanding of the body and sexual desires in which variations in sex characteristics and non-reproductive sexual behaviours such as homosexuality were attributed to anomalies in the internal secretions produced by the testes or the ovaries. Biotypology, a new brand of medical science conceived and led by the Italian endocrinologist Nicola Pende, employed hormone research to study human types and hormone treatments to normalise individuals who did not conform to accepted medical norms. Latin American medical doctors, eugenicists, and sexologists took up biotypology with enthusiasm. This article considers the case studies of Italy, Argentina, and Brazil, and analyses the work of medical doctors who adopted a biotypological mode of reasoning and employed to various extents hormone therapies in their practice. By focusing on hormone therapies that aimed to normalise secondary sexual characteristics and the sexual instinct, the article suggests that while the existence of normality was contested to the point that a number of medical scientists argued that no such thing existed, the pursuit of normality was carried out in very practical terms through the new medical technologies hormone research had introduced.

The paper is devoted to investigation of the influence of the family structure and family attitudes, child-parent relationship, styles of family upbringing on the intellectual develop- ment of pre-school-age children. Attention is paid to the analysis of the influence of parents and children gender. The sample included 150 children, 150 mothers and 75 fathers, all the families live in St. Petersburg. Results of the study reveal a significantly greater influence of the child's parent-child relationship and family atmosphere on the intellectual develop- ment in comparison with its structure. Negative impact of attitudes on the severity, harsh- ness, acceleration the development of the child on the intellectual development is revealed. Influence of parents’ gender on intellectual development of children manifests in the lead- ing role of the father’s relationship in girls IQ results, and mother’s parental attitudes in boys IQ results. The authors of the article reveal the importance of the adequacy of the system of regulation and control, severity of requirements for the development of girls; lack of parental custody and adequacy to meet the needs — for the development of boys. The authors outline the significant role of preschool children perception, especially girls, of the emotional atmosphere in the family in their intellectual development.

Background. The consequence of iodine deficiency is a decrease in the secretion of thyroid hormones, which adversely affects the immune system with the development of somatic and predisposition to frequent respiratory diseases. The purpose was to investigate the iodine supply of the body of children with recurrent respiratory infections (RRI) by studying the organification and inorganic fractions of iodine in the serum and excretion of iodine in the urine. Materials and methods. The study was conducted by simple sampling, taking into account the characteristics of the clinic course of respiratory disease. Clinical and laboratory and instrumental examination was performed in 60 children aged 3 to 11 years with a diagnosis of RRI. The concentration of iodine in urine, the level of inorganic and organification iodine in the blood were studied. Results. The clinical picture presented with the symptoms of intoxication, fever, and catarrhal symptoms typical of RRI. In children with severe RRI experienced a clear decrease in the iodine level to 57.34 μg/l (p < 0.05) and a decline in the blood content of total iodine and iodine organification by 31.12 and 39.11 % (p < 0.001), respectively. The concentration of inorganic iodine was significantly higher (p < 0.001). Such results indicate a “wrong” subcellular distribution of iodine into fractions in the inflammatory process caused by RRI. The children with detected iodine deficiency demonstrated a more severe course of RRI. There was a moderately negative relationship between the levels of organification and inorganic iodine (r = –0.515; p < 0.05) and a direct relationship between the blood concentrations of total and organification iodine (r = 0.899; p < 0.05). Conclusions. The course of RRI in patients with iodine deficiency is characterized by an increase in the level of inorganic iodine, a decrease in organification iodine and total iodine, the deepening of these changes correlates with the severity of the respiratory disease.

Obesity In Children

Abstract BackgroundOverweight and obesity in children have a negative impact not only on the physical development but also on the mental health of children. That is why researchers are constantly looking for possible causes of such high frequency of this phenomenon. One of the environmental factors contributing to abnormal weight changes in children may be maternal exposure to adverse environmental factors during pregnancy, which in previous studies led to inconclusive results showing both overweight and obesity and underweight in children. The aim of the study was to examine the relationship between prenatal stress and body weight status. MethodsThe cohort study included 254 girls and 276 boys. Information on prenatal stress was collected with a questionnaire completed by a parent/guardian of a 6–12-year-old child. We assessed the body mass status on the basis of BMI according to the IOTF criterion and on the basis of body fat according to McCarthy criterion. ResultsThe results of our study show that the prenatal stress was related to increased risk of overweight (OR 2.14, 95%CI: 1.25-3.65) diagnosed on the basis of body fat cut-off points, but not when the BMI was a diagnostic criterion (OR 1.03, 95%CI:0.58-1.83). ConclusionThe method of diagnosis based on the fat content appears to be an indicator of the occurrence of abnormalities in body composition due to prenatal stress more sensitive than that based on the BMI. Level of evidence: Evidence obtained from well-designed cohort or case-control analytic studies

Abstract Background: Borax and Formalin are often misused by naughty producers as additional preservatives in children's snacks such as cilok, meatballs, noodles and other foods. BPOM data shows that throughout 2012, the incidence of poisoning due to consuming food occupied the highest position, namely 66.7%, one of the causes of food poisoning was the presence of chemical contamination in children's snack foods, such as borax and formalin. The accumulation of these substances in the body can have a negative impact on health. Purple trumpet flower is a simple detection material to find out the presence of borax and formalin in food. The aim of community service is to increase knowledge in mothers of school-age children, how to detect simple borax and formalin in children's snacks with purple trumpet flowers. Methods: The method by means of detection training is how to detect simple borax and formalin in children's snacks with purple trumpet flowers. Results: From the results of community service, that mothers with 90% of school-age children can do a simple way of detecting borax and formalin in children's snacks with purple trumpet flowers. Conclutions: that mothers of school-age children can do a simple way of detecting borax and formalin in children's snacks with purple trumpet flowers.

A list of 1298 species and 172 genera of Chrysomelidae from the subfamily Galerucinae (sensu stricto) with the males having at least one form of secondary sexual characteristic (SSC) is presented. The number of species amounts to 24% of the total Galerucinae presently known from all over the world—a very significant amount. The SSCs comprise various types of modified structures found on all parts of the body—head, thorax, and abdomen. They are not variable but species specific. Illustrations from selected 87 species that include 84 images and 15 line drawings showing various types of SSC are provided. The amazing array of SSCs from the Galerucinae offers a large and taxonomically diverse set of data that are not comparable with other subfamilies in the Chrysomelidae and may be useful in phylogenetic analysis of the family.

Operational Information

Differentiation and individualization of school physical education allows one to take into account the features of each child, its existing experience and level of achievements, interests and inclinations. To organize a differentiated approach during a teacher of physical culture, operational information on the physical state of students of a particular class is required. The purpose of the work is to analyze the physical condition of children 7-8 years for planning physical activity during exercises. Methods of research: analysis of scientific and methodological literature; Pedagogical observation and experiment; testing; Methods of mathematical statistics. Organization of research. The research was conducted on the basis of School No. 66 of the Dnipro. 125 children 7-8 years have participated in the study. The processing of test results was carried out using the KIFZOS Computer Program. Research results. The age of 7-8 years is the most calm period in the development of children, during which there is a smooth change in the structures and functions of the organism. However, despite the slowdown in growth rates, the length of the body in girls and the boys increases more intense than body weight. The body proportions are changing, the volume of the chest increases, that is, there is a "pulling" of the body. A clear difference between boys and girls in anthropometric indicators almost not observed. The general assessment of the level of health of children under the method of G. L. Apanasenko allowed to distribute examined schoolchildren to 3 groups by levels of somatic health. Most children belonged to the group "Patients". Among boys, low level of physical fitness is observed more in children for 8 years - 63.0% (7 years - 33.3%). High levels are not fixed. Among girls, low levels of physical fitness had 29.4% - 7 years, 14.3% - 8 years. High levels were observed in 7.1% of girls 8 years. Conclusions. Thus, an individual assessment of the physical state of school-age children allows you to determine the means and methods of development of motor qualities, taking into account sensitive periods and age-sexual characteristics of students. The obtained data indicate a low level of physical condition of children, which determines the use of a differentiated approach in planning physical activity. Prospects for further research. We plan to develop exercises for increasing the level of physical status of schoolchildren who can be used when working on-line.

Purpose — study of the severity of secondary sexual characteristics in girls with general and genital infantilism in the early reproductive period. Materials and methods. 150 girls with general and genital infantilism were examined. All examined girls underwent clinical, functional, hormonal, biochemical, radiological, genetic and laboratory tests. The average age of girls was 19.56±0.13 (17–22) years. The average weight of the examined was within 55.37±1.56 (32–98) kg, height 1.57±0.13 (1.36–1.71) m. The body-mass index was 22.5±0.48 (15–48). The severity of secondary sexual characteristics was assessed according the J. Tanner scale. Results and conclusions. It was found that adolescents with general infantilism (hypogonadotropic hypogonadism) have a significant delay in the development of secondary sexual characteristics against the background of mild hirsutism (р<0.05). In Patients with genital infantilism (hypergonadotropic hypogonadism), significant axillary and suprapubic hair growth at the background of poor development of the mammary glands was noted. Also the moderate degree of hirsutism was confirmed. With normogonadotropic hypogonadism, the development of secondary sexual characteristics corresponds to similar indicators of practically healthy girls. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. The authors declare no conflicts of interests. Key words: general infantilism, genital infantilism, hypogonadotropic hypogonadism, normogonadotropic hypogonadism, hypergonadotropic hypogonadism, hirsutism.

Efficient Elimination

In many animals, including us, the genetic sex is determined at fertilization by sex chromosomes. Seemingly, the sex determination (SD) in human and animals is determined by the amount of constitutive heterochromatin on Y chromosome via cell thermoregulation. It is assumed the medulla and cortex tissue cells in the undifferentiated embryonic gonads (UEG) differ in vulnerability to the increase of the intracellular temperature. If the amount of the Y chromosome constitutive heterochromatin is enough for efficient elimination of heat difference between the nucleus and cytoplasm in rapidly growing UEG cells the medulla tissue survives. Otherwise it doomed to degeneration and a cortex tissue will remain in the UEG. Regardless of whether our assumption is true or not, it remains an open question why on Y chromosome there is a large constitutive heterochromatin block? What is its biological meaning? Does it relate to sex determination, sex differentiation and development of secondary sexual characteristics? If so, what is its mechanism: chemical or physical? There is no scientifically sound answer to these questions.

Background: Reading disabilities (RD) are the most common learning disabilities, affecting 3-7% of school-aged children in North America. RD is associated with increased risk for comorbid language-based disorders including early language delay (ELD), speech sound disorders, and language impairments. Despite decades of research on the relationship between RD and these disorders, questions remain as to the strength of their associations. This study is the first of this size to assess all four disorders in a sample of children with RD. Method: We examined the association these disorders in a large, well-characterized family-based sample, recruited for reading difficulties in school-aged children. Parents of 492 families (674 children) completed a questionnaire that queried ELD, and current speech and language difficulties in their children. Children were also directly assessed for multiple quantitative measures of language and reading. Children were divided into three groups: Reading Disabled (RD), Intermediate Readers (IR), and Typical Readers (TR). Results: We found that the parents of the RD and IR groups reported significantly more ELD and current speech and expressive/receptive language difficulties in their children, compared with the TR group. When examined further, we found ELD was associated with poorer performance on word reading and decoding tasks, as well as with speech and language difficulties. Conclusion: The results demonstrate multiple significant associations between reading difficulties, ELD, speech and language, especially in children with severe RD. The results add to research supporting comorbidity between these disorders and will help inform teachers and psychologists when assessing and treating children’s language-based disabilities.
