Hiperinsulinemia and ketotic hypoglycemia as the most common forms of hypoglycemic states in childhood
Hypoglycemia is defined asplasma glucose level sufficiently low to result in neurological damage. In the new-born age, the incidence of hypoglycemia ranges from 0.4-11.4%. Etiologically, low levels of plasma glucose can result from the hormonal or metabolic disorders; high doses of insulin, drug poisoning, liver disease or systemic disorders. The most common cause of severe and permanent hypoglycemia in the neonatal age group is congenital hyperinsulinism - the result of pancreatic cells hyperplasia and/or adenoma. Between two and five years of age, the most common form of hypoglycemic state is ketotic hypoglycemia of childhood, caused by limited amount of substrate. Diagnostic criteria include biochemical confirmation of low of glucose and/or high insulin levels, blood hormone testing (epinephrine, cortisol, growth hormone, glucagon levels), as well as metabolic screeningfor gluconeogenesis, glycogenolysis, and lipolysis disorders and disarrangements of fatty acid oxidation. Therapy is directed towards the substrate supplementation and the application of medications and fuels aiming atrapid attainment of normoglycemia (fruit juices, parenterally applied glucose and dextrose, glucagone, corticosteroid therapy); diazoxide and somatostatin therapy is indicated for patients with hyperinsulinemia.

Histological analysis of tissue of the interdental space before and after correction of irregular fillings: Experimenting on animals
Correlation of fillings on the tooth and changes in the tissues having direct contact with the tooth aroused keen interest amongst many professionals. Irregularly shaped fillings can damage the periodontal tissues. The primary indicator of the validity of the dental work is its ability to ensure the preservation of normal physiological status of the tissue, primarily gingival, alveolus and periodontum. The main purpose of this paper is to make histological assessments of the tissue of the interdental region before and after correction of irregular filling in experimental animals. The research was conseived as a histiological study with experimental animals ( rabbits). The tested teeth were divided into two groups: a) the experimental group consisted of teeth with irregular fills, and b)the control group consisted of teeth with regular fillings and healthy teeth. The experiment carried out under general anesthesia. The experiment was being monitored over 12-month period. Having been expired the first part of the experiment , after 6-month period, in experimental animals, it was carried out the second part of the one consisting of the correction of irregular fillings. The second part of thhe experiment was closely monitored a month, three and six months after the correction of irregular filings. After sacrificing the animals, tissue was prepared for histological analysis. Histological analysis showed changes in the periodontal tissues prior to correction of irregular fillings and significant improvementof the tissue of the interdental region after correction of the same ones. The pathological changes occuring in the periodontal tissues are not irreversible since after correction of irregular filligs are being lost mainly.

Precision of Moyers table values of predicting C-P2 segment applicable to our population
Introduction: One of the basic tasks of the orthodontist is to establish a proper dental array, to provide a favorable mastication function and an adequate appearance of the maxillofacial complex.Aim: The aim of this paper was to determine whether the values obtained from Moyers' tablets within the 75% probability correspond to the values the width of the side segment measured on our population. Subjects and method: The study included 60 people with a constant dentition of age from 15 to 18 years (30 men and 30 women). Results: The total tooth width of the side segment in the upper and lower jaw obtained from Moyers's analysis is significantly higher than Our findings, regardless of gender, with an average of about 1mm. Conclusion: We have defined the new regression equations for calculating the size of the C-P2 segment for the upper and lower jaws especially for men and especially for females.

Effect of topical ozone therapy on denture-related traumatic ulcers: A case report
Introduction: Dental related oral mucosal lesions are most often complications of wearing removable dentures. Painful lesions treatment beside removing ethiologyical factor is symptomatic therapy. Recent investigations of ozone have reported that ozone can induce the wound healing. Case raport: A patient with three ulcerative lesions subsequently developed as a result of wearing implant retained overdenture were included in the study. Each lesion recived conventional care whereas tested lesion recived topical gaseous ozone therapy additionaly. Ozone was applied directly on the musocal lessions for three times in 1 week (baseline-1.day-3.day). The basic result were changes in greatest dimension of every lesion from first treatment and at days 1 and 3. Conclusion: The current case report showed positive effect of gaseous ozone on accelerating the process of healing and pain reduction but future clinical studies are needed to confirm these findings.

Suicide as a cause of death with drug addicts
There were 351 drug addicts examined post mortem from 2006 till 2015 at The Institute of Forensic Medicine in Belgrade. In most of the cases death was accidental, caused by the use of psychoactive substances totaling 219(62,4%), followed by suicidal deaths 35 (10,0%) and deaths from traumas caused in traffic accidents. The most common manner of suicide was death by hanging (48,6%), jump from a height (28,6%), suicide by firearm (17,8%). There were no recorded suicides by overdose. The age of post mortem drug addicts where the suicide was a cause of death, did not statistically differ from others, accidental deaths, caused by the use of psychoactive substances. However, drug addicts died from traumas in traffic accident were statistically significantly younger in comparison to previous two groups. The median blood morphine levels concentration value did not statistically differ significantly in all three examined groups. Quite often there was alcohol presence in blood of drug addicts who died in traffic accidents.

Obstructive sleep apnea from the dentist point of view: The very first experiences
Obstructive sleep apnea (OSA) is the most common respiratory sleep disorder and present the occurrence of a minimum of five interruptions in breathing and/or the decrease in ventilation for more than 50%, minimum duration of 10 seconds, during one hour of sleeping (apnea/hypopnea index -AHI) with the existence of daytime and nighttime difficulties.The diagnosis of sleep-disordered breathing is made by polysomnography testing in specialized centers. Depending on the type and severity of the disorder different therapeutic modalities are available:hygienic-dietary regimen and lifestyle, use of oral appliances (OA), noninvasive ventilation with continuous positive airway pressure (CPAP)through a mask during sleep time and surgical approach to upper airways. CPAP is a gold standard in sleep apnea syndrome treatment, especially in severe forms of OSA.A therapy of choice for mild to moderate obstructive sleep apnea and at the same time an alternative treatment for CPAP intolerance are oral appliances.A mandibular advancement device and a tongue-retaining device are in use. Simplicity, portability, lack of noise, independence from a power source, and potentially lower cost, bring potential advantages over CPAP.By increasing the volume of upper airways, the number of obstructive breathing events is being significantly reduced, and arterial oxygen saturation is being improved. A close cooperation and surveillance by medical doctor and dentist is required, from the correct choice and drafting of oral appliance, through initial patient's accommodation to treatment, to long-term follow-up of therapeutic effect in sleep medicine laboratories.

Pulp and dentin modifications that occur after direct and indirect overlay with materials on the calcium hydroxide-base
When pulp tissue gets exposed, therapy procedures are supposed to promote healing and to ease forming of reparative dentin in order to preserve vitality and health of the pulp. Vital pulp therapy (VPT) procedure includes removal of the local irritants as well as application of protective materials directly or indirectly on tooth pulp. Vital pulp therapy may be used for the treatment of the reversible pulp diseases in order to promote root development and to form apical region which will ensure correct endodontic tooth treatment in later stages. There are numerous controversies concerning vital pulp therapy but mostly related to the choice of the materials, correct technique and evaluation of the final therapy results. The goal of the experimental research is to use scanning electron and polarized microscopy to analyze modifications on cellular and extracellular components of the tooth pulp after direct and indirect overlaying with materials on the calcium hydroxide basis (Calcimol VOCO USA). We will also determine the appearance of dental surface after direct and indirect overlaying and if Calcimol proves good and effective in dentinogenesis, we will propose it for clinical usage. Research has been conducted on experimental animals (pig). Materials used in this research were on calcium hydroxide - base, Calcimol. V class preparation has been applied on the teeth of the experimental group. Eleven teeth have been overlaids directly and the same number of teeth has been overlaid indirectly. After the preparation, materials based on calcium hydroxide have been applied and cavity has been closed with materials from the glass ionomer cement group (FUJI IX GC Japan). Teeth that were treated with pulp perforation had their chambers filled with materials on calcium hydroxide-base and their cavities were closed with glass ionomer cement (FUJI IX GC Japan). Correctly prepared teeth have been observed with SEM and polarization microscopes. Observing and analyzing of the results with polarization and scanning electron microscope in comparison with control group showed that gained results may have significant clinical implication in biological pulp treatment. Directly applied Calcimol observed through polarization microscope points to intensive changes in blood vessels and beginnings of erythrocyte disintegration, distinct extravasation, and appearance of the small necrotic spots. SEM analyzes shows contact of the amalgam-Calcimol without new amorphous dentinal structures. Indirectly applied Calcimol observed through polarization microscope points to newly formed dentinal structures, calcification cores surrounded by huge cells and blood vessels presence. SEM analyzes shows clear border between newly formed dentinal tubules and ordinary dentinal structure. Gained results suggest application of the Calcimol as a material for indirect pulp overlay while its application in indirect overlay isn’t indicated.

Takotsubo cardiomyopathy
Takotsubo cardiomyopathy was described for the first time by Sato in Japan in 1990. It is also called: stress cardiomyopathy, ampulla cardiomyopathy, transient left ventricular apical ballooning syndrome, "broken heart" syndrome and takotsubo-like left ventricular dysfunction. It is characterized by finding of transient abnormal wall motion of the left ventricle, without significant coronary artery stenosis (<50% of lumen), typically accompanied by chest pain, dynamic, reversible disorders of ST-T segment and a slight increase in levels of cardiac enzymes. Previously it was thought that this disease occurs primarily in older women, usually in menopause. With the increase of knowledge and experience about this cardiomyopathy, it is more and more often diagnosed in younger people of all ages, even in younger women during pregnancy or childbirth. Etiology of this disease still remains unknown. The trigger for development of this syndrome is usually, but not always, an intensive emotional or physical stress. Pathogenesis is still not clear enough. There are several pathogenetic theories, and the most widely accepted is a catecholamine theory. It is described seven different types of cardiac dysfunction until now, and the most common are apical akinesia of the left ventricle with a compensatory basal hyperkinesia (classical form), akinesia of the middle part of the left ventricle with preserved ability of contraction in the basal and apical regions (MLV form), biventricular akinesia and isolated right ventricular dysfunction. In this paper are presented the latest findings about this cardiomyopathy, by etiopathogenetic, clinical and therapeutic aspects.

Systematic review of factor validity of psychiatric scales in longitudinal studies
Validity shows the degree of concurrence between the results received by an actual measuring and that of what an instrument is supposed to measure. There are three main types of validity: content validity, criterion-related validity and construct validity. Factor validity is a special approach to constructive validity, tested by statistical analysis called factor analysis. Hamilton rating scale for depression and Montgomery-Asberg depression scale are the most widely used psychiatric instruments. The aim was to carry out a systematic review of the literature on factor structure of psychiatric scales reported in different times during longitudinal studies. The units of analysis were published papers obtained by searching the two bibliographic databases: MEDLINE and PsycINFO. Factor validity of the HAMD scale was reported in 6 (0.09%) of 6590 studies which used this scale, whereas the factor validity of the MADRS scale was reported in 4 (0.2%) of 2051 studies which used the MADRS scale. The difference between the first and the last measuring in relation to values was not statistically significant: median of the number of extracted factors of the HAMD scale (p=0.371), median of total explained factor variance of the HAMD scale (p=0.250), median of variance explained by the first factor of the HAMD scale (p=0.125). Factor validity of the MADRS scale in repeated measuring also did not have statistically significant difference for the following values: median of the number of extracted factors of the MADRS scale (p=0.174), median of variance explained by the first factor of the MADRS scale (p=0.125). Coefficients of concurrent validity of the HAMD i MADRS depression scales show the trend of increase in longitudinal studies and their values are for about a third higher at the end of studies than in their beginning. Low frequency of reporting the data about reliability and validity of applied rating scales is the main problem in using the meta-analytical methods effectively to study changes in adequacy of measures in longitudinal studies.

The impact of stress on occupational burnout among miners
Existence of stress at workplace leads to the occurrence of occupational burnout among miners. OBJECTIVE is testing of influence of stress on occupational burnout among miners. METHODS The research was designed as a cross-sectional study and covered 345 subjects, which were classified into three groups: two investigated groups, consisting of Miners A (142), Miners B (147) and Control group (56) consisting of administrative workers. The research was conducted in the Health Center ZveĆan, in the Medical Laboratory Service in ZveĆan and at the Institute of Occupational Medicine in Niš. The following questionnaires were used in the study: Questionnaire on basic sociodemographic indicators of respondents, Copenhagen Burnout Inventory (CBI), and Occupational stress assesment questionnaire. Data analysis was performed using the SPSS 16.0 software package. RESULTS The study of the presence of stressors in the workplace compared to the examined groups showed that a large number of stressors were evident, with the average value of all stressors at miners 2.60 ± 1.02, which is significantly above the average value of all stressors in the control group 1.85 ± 1.02. Above the total average of all stressors 2.60 ± 1.02, there is a large number of stressors. All stressors statistically significantly higher in miners compared to the control group (p <0.001) and the values of each individual stressor in the control group are below the average values of all stressors in miners (2.60 ± 1.02). High burnout level is present in 50.70% of Miners A, 46.90% of Miners B and 16.10% of Control group subjects. It was found that there is a statistically significant difference in the incidence of high burnout in relation to the investigated groups (p <0.001). DISCUSSION There is a large number of stressors among miners and their average value is significantly above the average value of all stressors in the control group. The stressors are both quantitatively and qualitatively different in relation to the control group. A large number of high-strength stressors significantly increases the probability of stress in both groups of miners and contributes to the occurrence of occupational burnout. There is a high exposure to stress among miners, and the impact of stress on occupational burnout has been proven in a large number of research in different professions. This was also confirmed in miners, among whom high exposure to stress led to high occupational burnout, which is statistically significant in relation to the control group. CONCLUSION The results of the study showed that there are a large number of stressors in the miner groups, that the average value of all stressors in miners is significantly above the average value of all stressors in the control group, that there are a large number of stressors that are in strength above the total average of all mining stressors and that all stressors are statistically significantly higher in miners than in the control group. The strongest stressors are most important for stress, and the presence of a large number of stressors above the total average of all stressors not only increases the probability of stress, but also proves a great deal of stress, but also contributes to the intense occurrence of occupational burnout. The results of the study have shown that high burnout is present in about 50% of miners in both mines and that there is a statistically significant difference in the incidence of high burnout in relation to the control group. Occupational stress affects occupational burnout among miners.
