Introduction: Oral Lichen planus (OLP) is chronic inflammatory oral mucosal disease of unknown etiology. Basement membrane damage and T‑cell migration in OLP may be mediated by matrix metalloproteinases (MMPs). We examined the expression of matrix metalloproteinase 9 to support this hypothesis. Materials and methods: The study population consisted of 71 patients with OLP and 10 control patients with oral fibromas. Indirect immunohistochemistry was used for detection of MMP 9 expression (polyclonal rabbit anti‑human MMP antibody). Results: In all cases of OLP, the MMP‑9 expression was seen mainly in the area of lymphocytic inflammatory infiltrate in the lamina propria including lymphocytes within the overlying epithelium. In addition, it was observed in the epithelial keratinocytes, particularly in the stratum basale and stratum spinosum with occasional positivity in the superficial layer. Fibroblasts and endothelium of small vessels in the lamina propria showed MMP9 expression as well. In all cases of oral mucosal fibromas, the MMP‑9 expression was seen only in fibroblasts and in endothelium of small vessels with occasional positivity within the overlying epithelium. It remains unclear, whether MMP‑9 is directly connected to OLP pathogenesis., Vladimíra Paulusová, Jan Laco, Ivo Dřízhal, Radovan Slezák, and Literatura 24
Cíl práce: Analýza výsledků extrakčních vaginálních operací ve FN Motol v období let 2007 – 2011. Typ studie: Retrospektivní analýza Soubor a metodika: Analýza 341 vaginálních extrakčních porodů – frekvence využití jednotlivých instrumentů, indikace k jednotlivým extrakčním operacím, mateřské a neonatologické komplikace. Výsledky: V daném období stouplo využití extrakčních metod z 0,81 % na 3,55 %. Tento stoupající trend byl dán zejména zvyšující se frekvencí využití vakuumextraktoru (VEX). Na našem pracovišti se VEX do roku 2007 nepoužíval vůbec, v roce 2011 již tvořil 92 % všech extrakčních operací (nárůst z 0 % na 3,27 %, forceps pokles z 0,81 % na 0,28 %). Indikační schéma k využití jednotlivých instrumentů se v průběhu let také změnilo, dominantou k využití forcepsu byla hypoxie, v roce 2011 při vzrůstající oblibě vakuumextraktoru tvořila právě hypoxie již 50 % indikací k jeho využití. Četnost poranění matky i novorozence byla nižší při použití vakuumextraktoru, kefalhematom novorozence v 7 % u VEXu a 13 % u forcepsu. Závěr: V daném období došlo na našem pracovišti k celkovému zvýšení četnosti extrakčních porodů, a to zejména vlivem použití vakuumextraktoru. Vakuumextraktor je dle našich dat spojen s nižší mateřskou a novorozeneckou morbiditou. Neonatologické výsledky obou metod jsou srovnatelné, mírně však ve prospěch vakuumextraktoru. Výjimkou je jeho neúspěšné použití., Objective: To analyze the results of assisted vaginal deliveries at the Motol University Hospital for the period 2007–2011. Type of study: A retrospective analysis Material and Methods: Analysis of 341 vaginal assisted deliveries - frequency of individual instrument use, indications for assisted vaginal deliveries, maternal and neonatal complications. Results: During the given time period the frequency of assisted vaginal deliveries increased from 0,81 % to 3,55 %. This increasing trend was mainly due to the increasing frequency of vacuum extractor (VEX) use. The first vacuum assisted vaginal delivery at our hospital was recorded in 2007. In 2011 this method already accounted for 92 % of all assisted vaginal deliveries (an increase from 0 % to 3,27 %; the frequency of forceps deliveries decreased from 0,81 % to 0,28 %). Over the years, indications for the use of instruments have also changed. Main indication for forceps delivery used to be hypoxia, but in 2011, with increasing popularity of vacuum extractions, it accounted only for 50 % of indications for its use. Frequency of maternal and neonatal injuries was lower when using vacuum extractor, newborn cephalhaematoma was recorded in 7 % when vacuum extractor was used and 13 % when forceps was used. Conclusion: During the given time period there was an overall increase of assisted vaginal deliveries at our department, mainly because of the vacuum extractor use. According to our data, vacuum extraction is associated with lower maternal and neonatal morbidity. Neonatal results of both methods are comparable, but slightly in favour of vacuum extraction, except cases of its unsuccessful application., P. Hanulíková, H. Hrubantová, R. Vlk, T.

Cíl: Hlavním cílem výzkumného šetření bylo zjistit, které faktory ovlivňují pouţívání ošetřovatelských diagnóz v klinické praxi. Dalším cílem bylo zjistit rozdíly v hodnocení faktorů ovlivňujících pouţívání ošetřovatelských diagnóz v praxi podle věku, vzdělání a typu pracoviště. Metodika: Pro získání dat byl sestaven nestandardizovaný dotazník zaměřený na zjištění faktorů ovlivňujících pouţívání ošetřovatelských diagnóz. Výzkumný soubor tvořilo 253 registrovaných všeobecných sester z 9 zdravotnických zařízení v České republice. Sestry hodnotili na Likertově škále od 1 do 5, jak jednotlivé faktory ovlivňují pouţívání ošetřovatelské diagnostiky v praxi. Výzkumné šetření probíhalo od června 2011 do listopadu 2011. Výsledky: Podle našeho výzkumného souboru nejvíce ovlivňují pouţívání ošetřovatelských diagnóz v praxi následující faktory: počet pacientů na 1 sestru, administrativní zátěţ, syndrom vyhoření, nedostatek času, rozdíly v teorii a praxi a nedostatek personálu. Statisticky významné rozdíly v hodnocení faktorů podle věku byly zjištěny v hodnocení 2 faktorů: rozdíly v teorii a praxi, nedostatek motivace. Podle dosaţeného vzdělání byly statisticky významné rozdíly zjištěny v hodnocení 4 faktorů: nejednotnost ošetřovatelských diagnóz, terminologie diagnóz, rozdíly v teorii a praxi, rutinní práce. V závislosti na typu pracoviště byly statisticky významné rozdíly nalezeny v hodnocení 5 faktorů: terminologie diagnóz, rozdíly v teorii a praxi, nedostatek praktických zkušeností s ošetřovatelskou diagnostikou, rutinní práce, syndrom vyhoření. Závěr: Rozeznání faktorů ovlivňujících pouţívání ošetřovatelských diagnóz v praxi a zlepšení institucionální podpory můţe ulehčit implementaci ošetřovatelské diagnostiky v klinické praxi, Aim: The main aim of the study was to identify which factors influenced the use of nursing diagnoses in clinical practice. Another aim was to ascertain whether age, education and type of workplace affected the relative importance accorded to these factors. Methods: A non-standardized questionnaire on factors influencing the use of nursing diagnoses was administered to a sample consisting of 243 registered general nurses from 9 healthcare facilities in the Czech Republic. Using Likert´s 5-point scale, the nurses rated the importance of several factors in influencing their use of nursing diagnoses in practice. The research was conducted between June 2011 and November 2011. Results: Based on our sample, there are several factors which influence the use of nursing diagnoses in practice. Some of them are: number of patients per nurse, administrative strain, burnout syndrome, lack of time, discrepancies between theory and practice, lack of staff. Statistically significant age-related differences in rating factors were found for the following: discrepancies between theory and practice, lack of motivation. Statistically significant differences in ratings relative to education were found for four factors: disunity of nursing diagnoses, diagnostic terminology, discrepancies between theory and practice, workplace routine. Based on type of workplace, statistically significant differences in ratings were found for five factors: diagnostic terminology, discrepancies between theory and practice, lack of practical experience in nursing diagnostics, workplace routine, burnout syndrome. Conclusion: Recognizing the factors which influence the use of nursing diagnoses and enhancing institutional support can facilitiate the implementation of nursing diagnostics in practice., Helena Macková, Renáta Zeleníková, and Literatura 14
Cieľ: Cieľom štúdie bolo analyzovať faktory ovplyvňujúce dentálnu hygienu, medzi ktoré patrí konzumácia sladkostí a sladených nápojov u školskej mládeže z hľadiska veku a pohlavia a zároveň analyzovať výskyt dentálnej hygieny počas dňa. Metodika: Súbor respondentov tvorilo 1187 žiakov (620 dievčat a 567 chlapcov) vo veku 11, 13 a 15 rokov v oblasti stredného Slovenska. Zber údajov prebiehal v období máj 2010 až jún 2010. Na zber údajov bol použitý štandardizovaný dotazník vytvorený pre potreby HBSC štúdie (Health Behaviour in School – aged Children). Výsledky boli vyhodnotené Chí-kvadrát testom. Výsledky: Sladkosti a kolu v jednotlivých vekových kategóriách konzumuje každý deň alebo viac krát za deň približne tretina respondentov. Výskyt umývania zubov viac ako raz denne je približne rovnaký vo všetkých vekových kategóriách od 53% u 11 ročných chlapcov do 64% u 15 ročných dievčat. Vo všetkých vekových kategóriách dievčatá udávajú častejšie umývanie zubov v porovnaní s chlapcami. Záver: Výsledky poukazujú na zvýšenú konzumáciu sladkostí a koly počas dňa u školskej mládež stredného Slovenska, čo môže spôsobovať zvýšenú kazivosť zubov. Dentálna hygiena je v našom súbore respondentov nedostačujúca. Na základe získaných výsledkov je možné konštatovať, že potreba zvyšovania úrovne vedomostí nielen detí, ale aj rodičov o zásadách správneho stravovania a o zásadách dentálnej hygieny je neodmysliteľnou súčasťou výchovy k zdraviu a preventívnych opatrení v školskom veku., Aim: The aim of the study was to analyse the factors affecting dental hygiene such as consumption of sweets and sweet soft drinks in school-aged pupils in terms of their age and gender and at the same time to analyse the occurrence of dental hygiene during the day. Methods: The set of respondents consisted of 1187 pupils (620 girls and 567 boys) at the age of 11, 13 and 15 years in the area of central Slovakia. The data collection was conducted in the period of May 2010 to June 2010. For data collection was used standardized questionnaire for HBSC studies (Health Behaviour in School–aged Children). The results were analysed by Chi-square test. Results: Approximately one third of respondents in each category consumes sweets and Coca-cola every day or several times a day. The occurrence of cleaning the teeth more than once a day was equally proved in all age groups ranging from 53% in 11 years old boys to 64% in 15 years old girls. The girls of all age groups indicate more frequent cleaning of teeth in comparison with boys. Conclusion: The results show increased consumption of sweets and Cocacola during the day in the school youth from central Slovakia, which may cause an increase in tooth decay. Dental hygiene in our set of respondents is insufficient. Based on the obtained results is possible to state that the need for higher level of knowledge, not only in children but also in parents about the principles of proper diet and proper dental hygiene is the integral part of the preventive measures and health education at school age., Mária Kožuchová, Martina Bašková, and Literatura 18
Účel studie: Hlavním cílem studie bylo odhadnout dosažení patologické kompletní odpovědi nemocných trpících lokálně pokročilým adenokarcinomem rekta po předoperační (neoadjuvantní) chemoradioterapii (CHRT) s využitím individuálních farmakokinetických parametrů 5-fluorouracilu (5-FU). Sekundárním cílem bylo hodnocení bezpečnosti a snášenlivosti léčby. Tato otevřená prospektivní studie podporovaná grantem IGA NS 9693–04/2008 zahrnula 34 dospělých s lokálně pokročilým karcinomem konečníku ozařovaných do celkové dávky 50,4 Gy ve 28 frakcích po 1,8 Gy 10–15 MV paprsky v režimu 5 + 2 (5 dní radioterapie, 2 dny volno) s kontinuálně podávaným 5-FU v i. v. infuzi 200–1000 mg/m2 po dobu 4–5 týdnů kontinuálně 7denní infuzí. Chirurgická resekce následovala 4–6 týdnů po ukončení CHRT a po klinickém restagingu. Hodnocena byla klinická a patologická odpověď na chemoradioterapii pomocí zobrazovacího (MR) a histopatologického vyšetření, vyjádřená v % jako reziduální choroba. Výsledky a závěr: Výsledek dokládá vztah mezi velikostí kumulativní dávky 5-FU a kumulativní AUC 5-FU (r = 0,61, p < 0,001). Podobný vztah byl prokázán mezi kumulativní AUC 5-FU a metabolickým poměrem (poměr dosažených plazmatických koncentrací neaktivního metabolitu dihydrofluorouracilu (5-FUH2) ku koncentracím 5-FU, r = -0,80, p < 0,0001). Kumulativní AUC korelovala se stupněm odpovědi na léčbu (r = – 0,53, p < 0,005) a určovala také stupeň toxicity léčby. Pokud bychom chtěli dosáhnout kompletní patologickou odpověď, pak by denní dávka 5-FU měla být u středně rychlého metabolizéra >350 mg/m2 a kumulativní AUC1–39 dní > 50 mg/L*h. U žádného z nemocných nebyla nalezena mutace v genu pro dihydropyrimidindehydrogenázu (DPD) a multidrug resistance-1 protein (MDR-1), přesto byla nalezena vysoká interindividuální variabilita v dosažených plazmatických koncentracích 5-FU, a to i s ohledem na cirkadiální rytmus kinetiky léčiva., Background and Purpose: The main goal of the present study was to estimate the early patients´response following neoadjuvant chemoradiotherapy (CHRT) based on 5-fluorouracil (5-FU) with curative aim in relation to plasma concentrations and pharmacokinetic parameters of 5-FU. Secondary objectives included evaluation of the safety and tolerability of the regimen. Patients and Methods: This open prospective study enrolles 34 adult patients with locally advanced rectal cancer, who received 5-FU 200 -1000 mg/m2 administered as a continuous i. v. infusion over 4–5 week and radiotherapy delivered with 10–15 MV photon beams at 1.8 Gy/fraction up o 50.4 Gy in 28 daily fractions for 5 days a week. Surgical resection with curative aim followed 4–6 weeks after the completion of CHRT and clinical restaging. Pathologic response evaluation and the rate of tumor regression was evaluated using tumor downstaging by MR, histopathological staging, and expressed as residual disease (%). Results and Conclusion: The outcome evidenced the correlation between the cumulative 5-FU dose and cumulative AUC of 5-FU (r = 0.61; p < 0.001). The similar relationship was demonstrated between the cumulative AUC and metabolic ratio (the plasma concentration od inactive metabolite dihydrofluotouracile 5-FUH2 to 5-FU; r = -0.80; p < 0.0001). The cumulative AUC was correlated with tumor regression rate (r = -0.53; p < 0.005) and determined toxicity grade. To reach pCR, the daily dose of 5-FU in patient with average metabolic ratio of 5-FUH2/5-FU should be >350 mg/m2 and the cumulative AUC1–39days > 50 mg/L*h. No mutation of gene for enzyme dihydropyrimidindehydrogenase (DPD) and mutidrug resistance-1 protein (MDR-1) were identified, although the interindividual variability of 5-FU plasma concentration was high, also with regard to circadial 5-FU pharmacokinetics variability., Jiří Grim, Miloš Hroch, Jaroslav Chládek, Ondřej Slanař, Jiří Petera, Jiřina Martínková, and Literatura 27
The important biological role of saliva in maintaining of the homeostasis of the oral cavity environment, preventing infection and tooth decay is widely accepted. Salivary glands insufficiency may violate the balance between health and disease. Clinical data indicated that the destruction, agenesis and aplasia of salivary gland commonly followed with hypo salivation, low salivary flow, which resulted in severe caries and periodontal disease. Salivary gland dysfunction also frequently found in preterm and low birth weight newborns. But the information about structural background of abnormal salivation in early childhood is still limited. A presence of any correlation between salivary glands structural development and intrauterine restrictions of fetal growth (IUGR) is unclear. The aim of present study was to determine morphological and morphometric peculiarities of human parotid gland in case of IUGR at late gestation. Material and methods: Parotid glands of twenty human fetuses 2022 weeks of gestation with diagnosed IUGR from late abortions material were compared with ten fetal glands in cases of induced abortions due to psychological reasons (control group). Tissue samples were immersionfixed in 10% buffered formalin solution, embedded in paraffin wax. Histological slides were stained routinely with hematoxylin & eosin, with Van Gieson's Stain. Microscopical examination was performed on magnification x 40 and x 100. Stereometric study by point count method at magnification x 40 allowed finding out volume fractions (VF) of glands parenchyma and stroma. VF of lobules components (glands wall, glands lumen, ducts wall, ducts lumen, vessels, intralobular connective tissue) were registered at magnification x100. Morphometry of the secretory portion of the parotid gland was conducted on the Zeiss microscope with the help of the AxioVision Rel.4.8 program. The mature (differentiated) end pieces were measured, including their area (in mkm2), width, height, perimeter (all in mkm). Similar measurements were done in the foci of immature secretory ends of a gland. Additionally the mean height of the epithelial cells layer within the mature secretory end pieces was measured. The differences were analyzed by methods of mathematical statistics using the software Microsoft Excel; data was compared with control measurements by Students ttest. Results: The results of present research have shown the delayed differentiation of fetal parotid glands parenchymal components in case of IUGR. The parenchymal VF did not reach control values. Furthermore, VF of lobules components was also decreased. Ducts lumens appeared to be significantly narrower than at physiological gestation. Interlobular and intralobular connective tissue stroma, in contrast to the controls, occupied vast areas, and their volume fraction was increased. Deficit of the parenchymal components of the gland was enhanced by slower maturation of glands. In cases with IUGR, differentiated glands occupied smaller area, with reduced width, height and perimeter. Epithelium lining the differentiated glands is characterized by significantly lower height compared to the control group. Delayed differentiation resulted in higher proportion of immature glands. Their area, width, height and perimeter increased. IUGR was also accompanied with a variety of pathological changes. Conclusion: Present evidences suggest that IUGR leads to impaired growth and maturation of the parotid gland. Structural immaturity and lack of differentiated parenchymal elements of the organ may form the basis of its secretory functions lesion. The finding tends to support the hypothesis that the mechanism behind the increased risk of dental pathology in preterm, low birth weight and retarded children is centred at structural and functional immaturity of salivary gland., Sergiy Morozov, Olga Reshetnikova, and Literatura
INTRODUCTION: Autologous stem cell transplantation (ASCT) became standard of care for patients with multiple myeloma (MM) under the age of 65 years. We routinely perform ASCT for newly diagnosed MM since 1996 in our department. PATIENTS AND METHODS: We retrospectively analyzed all 285 transplants in 185 patients done for MM from January 1996 till December 2010. We analyzed overall survival (OS) and progression-free survival (PFS) regarding conditioning, stage, complete or very good partial remission (CR, VGPR) achievement, renal impairment, single vs. double transplant. RESULTS: Estimated 10-years survival of the whole set of patients is 39% (median survival 95 months). Patients with renal impairment show same OS as those without (p = 0.22). Patients show similar overall survival and event free survival regardless of type of transplant. We observed better outcome in terms of overall survival in patients treated with new drugs (p = 0.0014). Reaching CR or VGPR was not translated into better OS (p = 0.30) and EFS (p = 0.10). Also stage of the disease and whether single or double transplant was used did not make any significant difference in the outcome. CONCLUSION: Stem cell transplantation greatly improved outcome of patients with MM. Poor outcome of allogeneic transplantation in our group of patients is related to high transplant related mortality (20% vs. 0%) and unexpected high relapse rate. There is a trend towards better survival, when new drugs are incorporated at any time in the course of the disease. This fact supports hypothesis that use of these drugs with ASCT should translate into better long-term outcome. and J. Radocha, V. Maisnar, A. Zavrelová, M. Cermanová, M. Lánská, M. Kmonícek, L.
