Cytological Characteristics

Objective. To determine the relationship between metabolic parameters and cytological characteristics of the buccal mucosa in obese children. Patients and methods. An open cross-sectional case-control study included 78 schoolchildren aged 9 to 15 years, 44 of them were obese. We determined body mass index, lipid metabolism parameters (total cholesterol, high- and low-density lipoprotein cholesterol, apolipoproteins), and also cytological characteristics of buccal epithelial cells. Results. The number of buccal epithelial cells with condensed chromatin was by 10 times higher in obese children. A correlation was found between cholesterol concentrations and certain cytological parameters, but this correlation was statistically significant only in the pair “cholesterol – number of binucleated cells” (correlation coefficient 0.925, p = 0.05) in obese children and in the pair “total protein – binucleated cells” in practically healthy children. Conclusion. We confirmed the known data about specific characteristics of lipid metabolism in obese children that correlate with certain cytological parameters of the buccal mucosa, namely, an increased number of cells with chromatin condensation. This phenomenon is suggestive of activation of apoptosis in obese children. Keywords: buccal epithelial cells, obesity, schoolchildren, cholesterol

Background: The sulfur vapor consists of  SO2 and CO2 which are genotoxins that may cause the damage of DNA to the micronucleus in buccal epithelial cells. Micronucleus is a mass like a nucleus, measuring one-third of the nucleus. DNA damage can also be seen from changes in the morphology of epithelial cells. Objective: This study aimed to identify the effect of sulfur vapor exposure on the number of micronucleus and morphology epithelial cells in the oral cavity on the sulfur miner. Methods: The method of this study was analytic observational with a cross-sectional approach. The total sample of this study was 24  respondents divided into 2 groups, each group contained 12 respondents. Exfoliated buccal cells were collected by scrapping the buccal mucosa. The specimens stained using Hematoxylin and Eosin. Nucleus and cytoplasmic area were examined using image J 1.40 Results: The result showed the average number of buccal mucosa micronucleus on coal miners higher (35,50) than controls (11,58). The result of Independent-measures T-test obtained significant different on the number of micronucleus between sulfur miner and controls (p=0,000). The result of Independent-measures T-test on the nuclear area and cytoplasmic area between sulfur miner and controls obtained insignificant different (p=0,379 dan p=0,616). Conclusion: Based on this study can be concluded that sulfur vapor exposure affected on the number of micronucleus on sulfur miners, but did not influence morphology of epithelial cells.

Abstract The objective of this study was to reveal the likely genomic instability in children with chronic kidney disease (CKD) using micronucleus (MN) assay on buccal epithelial cells (BEC). We investigated the frequencies of micronuclei and other nuclear anomalies, such as nuclear buds, binucleated cells, condensed chromatin, and karyorrhectic and pyknotic cells in BEC. Children with CKD were grouped as follows: children in the pre-dialysis (PreD) stage (N=17), children on regular haemodialysis (HD) (N=14), and children who have undergone transplantation (Tx) (N=17). As a control group, twenty age- and gender-matched healthy children were selected. The MN frequency in BEC of all groups of children with CKD was significantly elevated (5- to 7-fold) as compared to the control group (p<0.001). In contrast, the frequencies of nuclear buds were not significantly higher in the study groups compared to the control group. The frequencies of binucleated cells and condensed chromatin cells were significantly higher in all subgroups of children with CKD relative to the control group (p<0.001). Our results show that the BEC of pediatric PreD, HD, and Tx patients with CKD display increased cytogenetic, cytokinetic, and cytotoxic effects. They also point to the sensitivity and usefulness of the BEC MN assay in the assessment of genetic susceptibility of patients with CKD.

Abstract Background Obesity in children and adolescents is associated with increased morbidity and mortality due to multisystemic impairment, including deleterious changes in lung function, which are poorly understood. Objectives To perform a systematic review to assess lung function in children and adolescents affected by obesity and to verify the presence of pulmonary changes due to obesity in individuals without previous or current respiratory diseases. Methods A systematic search was performed in the MEDLINE-PubMed (Medical Literature Analysis and Retrieval System Online), Embase (Excerpta Medica Database) and VHL (Virtual Health Library/Brazil) databases using the terms “Lung Function” and “Pediatric Obesity” and their corresponding synonyms in each database. A period of 10 years was considered, starting in February/2008. After the application of the filters, 33 articles were selected. Using the PICOS strategy, the following information was achieved: (Patient) children and adolescents; (Intervention/exposure) obesity; (Control) healthy children and adolescents; (Outcome) pulmonary function alterations; (Studies) randomized controlled trial, longitudinal studies (prospective and retrospective studies), cross-over studies and cross-sectional studies. Results Articles from 18 countries were included. Spirometry was the most widely used tool to assess lung function. There was high variability in lung function values, with a trend towards reduced lung function markers (FEV1/FVC, FRC, ERV and RV) in obese children and adolescents. Conclusion Lung function, measured by several tools, shows numerous markers with contradictory alterations. Differences concerning the reported results of lung function do not allow us to reach a consensus on lung function changes in children and adolescents with obesity, highlighting the need for more publications on this topic with a standardized methodology.

OBJECTIVE: To explain why adrenal androgens rise with increasing adiposity during childhood, the role of body mass index (BMI), leptin and IGF-I was studied. We also tested whether these parameters contribute to inducing premature adrenarche (PA). DESIGN: In a cross-sectional study, 26 prepubertal obese children were compared with a group of 26 prepubertal children of normal weight, and 30 children under observation for PA were compared with 30 healthy children, matched for gender, bone age and BMI. METHODS: Relative contributions of BMI standard deviation scores (SDS) and height SDS, as well as unbound leptin and IGF-I, to the levels of androgens, dehydroepiandrosterone sulfate (DHEAS) and Delta4-androstenedione (AD) were investigated by means of stepwise regression models. Logarithms of all hormones were standardised for age using residuals of a simple regression analysis, labelled by the suffix '(res)'. RESULTS: In the obese children, height SDS, IGF-I(res,) DHEAS(res) (all P<0.05), leptin(res) (P<0.01), and AD(res) (P=0.07) were higher than in the controls, and covariates were correlated with each other (leptin(res) versus BMI SDS r=0.71, IGF-I(res) versus height SDS r=0.61). In the stepwise regression analysis of control and obese children, BMI SDS explained 26% and leptin(res) explained 12% of the variability of DHEAS(res), but this percentage remained at 26% when both variables were simultaneously introduced into the model. In contrast, IGF-I(res) and BMI SDS alone each accounted for 15% of the variability of AD, and their joint influence accumulated to explain 28% of the variability of AD(res). In PA, neither BMI SDS nor leptin(res) were correlated with the increased androgens. CONCLUSION: Before the onset of gonadal activity in obese and control children, DHEAS levels, to some extent, are explained by BMI and leptin, while IGF-I in addition to BMI in part accounts for AD levels. Enhanced adrenal androgen secretion in children with PA, however, may be explained by parameters other than leptin or BMI.

To investigate and correlate total AgNOR area/Total nucleus area (TAA/TNA ) values in buccal epithelial cells of healthy individuals in different age groups. Material and Methodology:- In present study 50 healthy individuals are included with age ranging 10 to 60 years. These are divided into 5 groups.Group1-10-20year, Group2-20- 30year, Group3-30-40year, Group4-40-50year, Group5-50-60year. Oral epithelial cells collected with the help of cyto brush from buccal mucosa. Smears were prepared on clean glass slides and fixed with 95% alcohol. Fixed slides Smears were stained with AgNOR stain. Results: Statistically significant correlations were found between mean TAA/TNA values and age p < 0.001 for linear and p < 0.0001 for polynominal regression, and between AgNOR number and age, p < 0.001 for linear. Conclusion: There is a significant correlation between age and AgNOR amount (ribosome biosynthesis rate) in buccal epithelial cells of healthy individuals. AgNORs in buccal epithelial cells may be used for detection of age.

SUMMARY This study aimed to assess the prevalence of medical and nonmedical use of psychiatric medication among undergraduate students of health sciences from a public university in Brasil. Another objective was to determine the frequency of nuclear morphological abnormalities in the buccal mucosa of students using psychiatric drugs. A cross-sectional study based on a Web survey was carried out with 375 health sciences undergraduate students from schools of Pharmacy, Physical Education, Nutrition, and Medicine. Additionally, spontaneous genetic damages in exfoliated cells of the buccal mucosa of 41 individuals by counting micronucleus (MN) and binucleated (BN) cells frequencies were evaluated. The results showed 76 (20.3%) of students reported the use of psychotropic drugs after enrolling in university. The majority of these students were from Pharmacy and Medicine programs, females, aged between 18-25 years old, nonsmokers, alcohol addicts, and with a family history of mental illness. In addition, Medical students, individuals with high-income, who live alone and are in the last period of the program are more likely to use psychotropic drugs. Moreover, exposure to psychiatric medication was able to increase the number of binucleated cells. These results provide evidence that the use of psychoactive drugs is increased in the academic context and may be related to the failure of the cell cycle.

Background: Thyroid hormones influence nearly all major metabolic pathways. Their most obvious and well-known action is the increase in basal energy expenditure obtained by acting on protein, carbohydrate and lipid metabolism. The lipid metabolism is more influenced by the thyroid hormone. Methods: A cross-sectional study was conducted on 100 patients with suspicion of thyroid disorders were taken as cases. One hundred patients with normal thyroid profile and no history of other chronic diseases were taken as control group. Results: The serum TC, TG and LDL levels in hypothyroid individuals (both overt and subclinical) were significantly higher than euthyroid subjects but the levels were comparable between hyperthyroid and euthyroid group. Conclusion: Dyslipidemias are associated with thyroid disorders, so biochemical screening for thyroid dysfunction in all dyslipidemic patients. Therefore, patients presenting with dyslipidemia are recommended for investigation to explore thyroid dysfunction. Keywords: Thyroid profile, Total cholesterol, Triglycerides and LDL

Mealtime Environment

Parental feeding practices and mealtime routine significantly influence a child’s eating behavior. The aim of this study was to investigate the mealtime environment in healthy children and children with gastrointestinal diseases. We conducted a cross-sectional case–control study among 787 healthy, typically developing children and 141 children with gastrointestinal diseases, aged two to seven years. Parents were asked to provide data on demographics and describe their mealtime environment by answering to 24 closed-ended questions. It was found that the majority of the children had the same number of meals every day and at the same hour. Parents of both groups exerted considerable control on the child’s food intake by deciding both when and what their child eats. Almost one third of the parents also decided how much their child eats. The two groups differed significantly in nine of the 24 questions. The study showed that both groups provided structured and consistent mealtime environments. However, a significant proportion of children did not control how much they eat which might impede their ability to self-regulate eating. The presence of a gastrointestinal disease was found to be associated with reduced child autonomy, hampered hunger cues and frequent use of distractions during meals.
