Description:
Midazolam is a short acting sedative with small number of adverse effects. Administered orally, it is currently the most common form of conscious sedation in children. The objective of this paper is to describe effect of midazolam administered to children during dental treatment on their vital signs, and to monitor changes in children’s behavior. We described values of vital signs and behavior in 418 sedations conducted in 272 children between 1-12 years of age. To achieve the following results, we used data from 272 all first-time sedations. After administration of midazolam arterial blood pressure and blood oxygen saturation decreased by values which were not clinically significant. The heart rate increased, with values staying within the limits of physiological range. The speed of onset of midazolam’s clinical effects depends on age and dose. The lower age and dose correlated with the higher behavior score. The effectiveness of midazolam treatment is 97.8 %. Unwillingness of child to receive midazolam is predictor for disruptive behavior during sedation. 1.8 % of all sedation cases showed paradoxical reactions. The administration of midazolam in dose of 0.5 mg per 1 kg of child’s body weight is safe and could be recommended for dental treatment in pediatric dentistry., Jana Vasakova, Jana Duskova, Jitka Lunackova, Klara Drapalova, Lucie Zuzankova, Luboslav Starka, Michaela Duskova, Zdenek Broukal., and Obsahuje bibliografii

Description:
Je podán stručný souhrn nejdůležitějších endokrinních změn, které provázejí stárnutí u muže. Klíčovou je osa hypotalamus-hypofýza-testes, jejíž snížená výkonnost vede k relativnímu poklesu androgenů. Také snížený potenciál sekrece růstového hormonu je snížením androgenního zásobení ještě dále oslabován a podobně je tomu i u melatoninu. Specialni roli hraje nadledvinová kůra, která zásobuje organismus glukokortikoidy v podstatě ve stejné míře jako v období reprodukčního optima, ale nadledvinové androgeny, zejména dehydroepiandrosteron se svou pestrou škálou příznivých účinku na metabolismus, vykazují výrazný pokles s narůstajícím věkem. Suplementace chybějícími hormony je schopna v pozoruhodné míře zmírnit známky a symptomy endokrinosenescence., There is a brief summary of the most important endocrine changes going with man's ageing here. The essential is the hypotalamus - pituitary gland - testes axis, the decreased capacity of which leads to the relative androgens loss. The lowered potential of growth hormone secretion is also further impaired by lowered androgens supply and similar situation is with melatonine. Special role has adrenal cortex, which supplies the organism with glucocorticoids basically at the same extent as in the reproduction optimum period, but adrenal cortex androgens, especially dehydroepiandrosterone with its wide range of positive effects on the metabolism show significant decrease with ageing. The supplementation with missing hormones is able to moderate the signs and the symptoms of endocrinosenescence at noticeable extent., Luboslav Stárka, Lit: 30, and Souhrn: eng

Description:
The determination of steroid hormones and subsequent interpretation of results is accompanied by a range of difficulties. The amount of information that current technology can provide on the circulating concentrations of more than a hundred various steroid compounds can lead to problems with interpretation. The aim of this study is to help provide orientation in this maze of data on steroid hormones. First we focus on specific aspects arising from the pre-analytical phase of steroid determination that need to be considered when planning sampling, whether for diagnostics or research. Then, we provide a brief summary of the characteristics and diagnostic relevance of several steroid hormones and/or their metabolites: pregnenolone, 17α-hydroxypregnenolone, dehydroepiandrosterone, hydroxyderivatives of dehydroepiandrosterone, androstenedione, testosterone, estrone, estradiol, estriol, cortisol, cortisone, which in our institute are determined with validated LC-MS/MS methods. For these steroids, we also provide newly calculated reference values in fertile women according to the phase of their menstrual cycle and Obsahuje bibliografii

Description:
Starling’s original definition of a hormone from 1905 was “a hormone is a substance produced by glands with internal secretion, which serve to carry signals through the blood to target organs”. Today, this definition is understood to be lacking, but newer definitions also do not encompass the entire meaning of hormones as specific carriers of information. One main problem is that there is no delineation between hormones and other signaling molecules such as cytokines, growth factors or autacoid compounds. It seems that a precise definition is not even possible, since some cytokines and growth factors, such as the cytokines erythropoietin, lipocalin-2 and asprosin or fibroblast growth factor 23, act as hormones under certain conditions., Luboslav Stárka, Michaela Dušková., and Obsahuje bibliografii
