Abstract
Abstract: Tuberous sclerosis complex is a rare disease with high phenotypic heterogeneity, characterized by the appearance of multiplex hamartomas in the different organs. The disease is inherited by autosomal dominant manner, due to the mutations of two genes: the TSC1 or the TSC2. In this publication we present the cases of two young male and two middle-aged female patients, where pathogenetic differences of TSC1/TSC2 could not be verified by Sanger sequencing. However, multiplex ligation-dependent probe amplification confirmed different sizes of deletions in different regions of the TSC2 gene. All patients carry the typical clinical signs of the disease. However, the individual phenotypic variability is very different. With this manuscript, we would like to draw attention to the relative frequent rate of gross gene deletions.

Abstract
UNLABELLED Rheumatoid arthritis (RA) has been associated with osteoporosis. Quantitative computed tomography (QCT) is capable of assessing bone density and composition. We found lower bone density in RA compared to controls. Age and RA duration influenced bone density. QCT may be useful to assess bone metabolism in RA. INTRODUCTION RA is associated with generalized and periarticular osteoporosis. In addition to DXA that determines areal bone mineral density (BMD), peripheral QCT also detects volumetric BMD. QCT differentiates between total, trabecular, and cortical BMD. Here, we compared DXA and QCT in RA patients and healthy controls. METHODS BMD of 57 female RA patients and 32 age-matched healthy female controls were assessed by DXA. QCT of the forearm ultradistal region was also performed. Densitometry data were correlated with age, disease duration, disease activity, serum CRP, and anti-CCP levels. RESULTS Total bone density (310.4 ± 79.7 versus 354.0 ± 54.1 mg/cm3; p = 0.007) and attenuation (0.37 ± 0.05 versus 0.40 ± 0.03 1/cm; p = 0.001), trabecular density (157.6 ± 57.0 versus 193.8 ± 48.7 mg/cm3; p = 0.005) and attenuation (0.28 ± 0.03 versus 0.32 ± 0.04 1/cm; p < 0.0001), and cortical density (434.3 ± 115.8 versus 492.5 ± 64.0 mg/cm3; p = 0.006) and attenuation (0.44 ± 0.07 versus 0.47 ± 0.04 1/cm; p = 0.004) were significantly lower in RA. Both lumbar and femoral neck BMD, as well as T-scores, were significantly lower in RA versus controls (p < 0.001 in all cases). In RA, total and cortical QCT attenuation and density were associated with age, the presence of RA, and their combination. In contrast, trabecular density and attenuation were only affected by the presence of the disease but not by age. Also in RA, total trabecular and cortical density as determined by QCT significantly correlated with lumbar and/or femoral neck BMD as measured by DXA. Finally, anti-CCP seropositivity was associated with lower trabecular density and attenuation. CONCLUSIONS Both DXA and QCT may be suitable to study bone metabolism in RA. Areal BMD determined by DXA may correlate with volumetric bone density measured by QCT. Moreover, trabecular osteoporosis may be associated by the underlying autoimmune-inflammatory disease, while cortical osteoporosis may rather be age-related.

Abstract
The structural similarities between the inorganic component of bone tissue and geological formations make it possible that mathematic models may be used to determine weight percentage composition of different mineral element oxides constituting the inorganic component of bone tissue. The determined weight percentage composition can be verified with the determination of element oxide concentration values by laser induced plasma spectroscopy and inductively coupled plasma optical emission spectrometry. It can be concluded from calculated weight percentage composition of the inorganic component of bone tissue and laboratory analyses that the properties of bone tissue are determined primarily by hydroxylapatite. The inorganic bone structure can be studied well by determining the calcium oxide concentration distribution using the laser induced plasma spectroscopy technique. In the present study, thin polished bone slides prepared from male bovine tibia were examined with laser induced plasma spectroscopy in a regular network and combined sampling system to derive the calculated calcium oxide concentration distribution. The superficial calcium oxide concentration distribution, as supported by "frequency distribution" curves, can be categorized into a number of groups. This, as such, helps in clearly demarcating the cortical and trabecular bone structures. Following analyses of bovine tibial bone, the authors found a positive association between the attenuation value, as determined by quantitative computer tomography and the "ρ" density, as used in geology. Furthermore, the calculated "ρ" density and the measured average calcium oxide concentration values showed inverse correlation.

Abstract
Abstract. Weather Research and Forecasting (WRF) single-column model simulations were performed in the late summer of 2012 in order to analyse the diurnal changes of the planetary boundary layer (PBL). Five PBL schemes were tested with the WRF. From the radiometer and wind-profiler measurements at one station, derived PBL heights were also compared to the simulations. The weather conditions during the measurement period proved to be dry; the soil moisture was below wilting point 85 percent of the time. Results show that (1) simulation-based PBL heights are overestimated by about 500–1000 m with respect to the observation-based PBL heights, and (2) PBL height deviations between different observation-based methods (around 700 m in the midday) are comparable with PBL height deviations between different model schemes used in the WRF single-column model. The causes of the deviations are also discussed. It is shown that in the estimation of the PBL height the relevance of the atmospheric profiles could be as important as the relevance of the estimation principles.

Abstract
Medical therapy for Crohn’s disease has changed significantly over the past 20 years with the increasing use of immunosuppressants. In contrast, surgery rates are still high and evidence about the the changes in the outcome of Crohn’s disease over the past decades is scarce. Aims: The objective of this study was to analyze the evolution of the surgical rates and medical therapy in the population-based Veszprém county database. Methods: Data of 506 Crohn’s disease patients were analyzed (age at diagnosis: 31.5 years, SD: 13.8 years). Both hospital and outpatient records were collected and comprehensively reviewed. The study population was divided into three groups based on the year of diagnosis (cohort A: 1977–1989, cohort B: 1990–1998 and cohort C: 1999–2008). Results: Overall azathioprine, systemic steroid, and biological (only available after 1998) exposure was 45.8, 68.6, and 9.5%, respectively. The 1 and 5-year probabilities of azathioprine use were 3.2 and 6.2% in cohort A, 11.4 and 29.9% in cohort B, and 34.8 and 46.2% in cohort C. In multivariate analysis, decade of diagnosis (P<0.001), age at onset (P = 0.008), disease behavior at diagnosis (P<0.001), and need for systemic steroids (P<0.001) were significantly associated with the time to initiation of azathioprine therapy. Early azathioprine use was significantly associated with the time to intestinal surgery in Crohn’s disease patients; in a multivariate Cox analysis (HR: 0.43, 95% confidence interval (CI): 0.28–0.65) and after matching on propensity scores for azathioprine use (HR: 0.42,95% CI:0.26–0.67). Conclusions: This population-based inception cohort showed that reduction in surgical rates was independently associated with increased and earlier azathioprine use. Orv. Hetil., 2012, 153, 541–552.

Abstract
A terápiarezisztens, súlyos Crohn-beteg gyermekek kezelésére új lehetőséget nyújt az antitumornekrózis-faktor-α-terápia (infliximab). Jelen vizsgálat célja az infliximabterápia hatékonyságának, mellékhatásainak felmérése hazánkban, a gyógyszer gyermekgyógyászati alkalmazásának engedélyezésétől a 2008. december 31-ig terjedő időszakban. A vizsgált periódusban országosan 23 gyermek részesült infliximabkezelésben. Az indukciós terápia során a betegek 5 mg/ttkg infliximabot kaptak a 0., a 2. és a 6. héten, ahol meghatároztuk a betegség aktivitását jelző mutatót (pediatric Crohn disease activity index). Az infliximabkezelés során kedvező terápiás választ 18 betegnél (81,8%) tapasztaltunk, teljes remisszióba 13 gyermek került (59,1%). A számításokat 22 beteg adatai alapján végeztük. A kezelés 6. hetére a fistulák 70%-a bezárult. A gyógyszerrel összefüggésbe hozható akut infúziós reakció 2 betegnél jelentkezett, egy másik esetben anaphylaxiás reakció alakult ki. Késői mellékhatás három gyermeknél jelentkezett. A vizsgálatunkban részt vett, hagyományos terápiára rezisztens, súlyos Crohn-betegek döntő többségénél az indukciós infliximabterápia hatásosnak bizonyult.
