We sought to record the acquisition of antibiotic-resistant Escherichia coli (E. coli) in healthy infants in Northern Thailand and investigated potential determinants. Methods Stool samples from 142 infants after birth, at ages 2wk, 2mo, 4 to 6mo, and 1y, and parent stool samples were screened for E. coli resistance to tetracycline, ampicillin, co-trimoxazole, and cefazoline by culture, and isolates were further investigated for multiresistance by disc diffusion method. Pulsed-field gel electrophoresis was performed to identify persistent and transmitted strains. Genetic comparison of resistant and transmitted strains was done by multilocus sequence typing (MLST) and strains were further investigated for extra- and intra-intestinal virulence factors by multiplex PCR. Results Forty-seven (33\%) neonatal meconium samples contained resistant E. coli. Prevalence increased continuously: After 1y, resistance proportion (tetracycline 80\%, ampicillin 72\%, co-trimoxazole 66\%, cefazoline 35\%) almost matched those in parents. In 8 infants (6\%), identical E. coli strains were found in at least 3 sampling time points (suggesting persistence). Transmission of resistant E. coli from parents to child was observed in only 8 families. MLST showed high diversity. We could not identify any virulence genes or factors associated with persistence, or transmission of resistant E. coli. Full-term, vaginal birth and birth in rural hospital were identified as risk factors for early childhood colonization with resistant E. coli. Conclusion One third of healthy Thai neonates harboured antibiotic-resistant E. coli in meconium. The proportion of resistant E. coli increased during the first year of life almost reaching the value in adults. We hypothesize that enhancement of infection control measures and cautious use of antibiotics may help to control further increase of resistance.}, language = {en} } @phdthesis{Breitenbach2010, author = {Breitenbach, Andrea}, title = {Welche Kinder haben Einfluss auf das Scheidungsrisiko?}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-52258}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2010}, abstract = {In der Scheidungsforschung werden Kinder als ein zentraler Einflussfaktor der Ehestabilit{\"a}t thematisiert. Je nachdem welches Kindschaftsverh{\"a}ltnis oder Charakteristikum von Kindern vorliegt, ist mit der Erh{\"o}hung oder Verminderung der Ehestabilit{\"a}t zu rechnen. Zum Beispiel wird nach der Familien{\"o}kononmie, durch das Vorhandensein von unehelichen Kindern in einer Ehe die Ehestabilit{\"a}t vermindert, w{\"a}hrend eheliche Kinder das Scheidungsrisiko reduzieren. In den meisten Untersuchungen der Scheidungsforschung werden die unterschiedlichen Einfl{\"u}sse von Elternschaft auf das Scheidungsrisiko dennoch weniger gut beleuchtet. Weiterhin ist in Anlehnung an die Theorien davon auszugehen, dass der Einfluss von Kindern auf die Ehestabilit{\"a}t nur erforscht werden kann, wenn bei der Operationalisierung der Kindvariablen eindeutig nach Kindschaftsverh{\"a}ltnissen differenziert wird, dieses Vorgehen findet sich allerdings nur in wenigen Studien der Scheidungsforschung. Diese Dissertation versucht die L{\"u}cke zu schließen, indem sie die Einfl{\"u}sse unterschiedlicher Charakteristika von Kindern und verschiedener Kindschaftsverh{\"a}ltnisse auf die Ehestabilit{\"a}t mit den Daten des Familiensurveys 2000 methodisch korrekt und in einem m{\"o}glichst großem Spektrum untersucht. In dieser Arbeit werden die unterschiedlichen Kindschaftsverh{\"a}ltnisse und Charakteristika von Kindern so operationalisiert, dass der Einfluss anderer Effekte ausgeschlossen wird. Nur durch dieses Vorgehen k{\"o}nnen letztendlich die Einfl{\"u}sse von Kindern auf die Ehestabilit{\"a}t eindeutig aufgezeigt werden. Die Ergebnisse der Dissertation zeigen zum einen, wie die relevanten Theorien den Einfluss von Kindern auf die Ehestabilit{\"a}t begr{\"u}nden und zum anderen best{\"a}tigen die Befunde der multivariaten Analysen, dass in Abh{\"a}ngigkeit von Kindschaftsverh{\"a}ltnis oder Charakteristika der Kinder unterschiedliche Richtungen des Scheidungsrisikos zu berichten sind. Dadurch kann die Vermutung best{\"a}tigt werden, dass die exakte Differenzierung nach Kindschaftsverh{\"a}ltnissen und unterschiedlichen Charakteristika von Kindern und die methodisch korrekte Operationalisierung der Kindvariablen bedeutsame Unterschiede in den Scheidungsraten aufdeckt.}, subject = {Ehescheidung}, language = {de} } @phdthesis{Grimm2013, author = {Grimm, Susann}, title = {Validierung der deutschen Version der Parents' Postoperative Pain Measure PPPM-D bei Kindern im Alter zwischen 2 und 12 Jahren nach orthop{\"a}dischen Operationen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-83873}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2013}, abstract = {HINTERGRUND: Eltern spielen im Rahmen der postoperativen Schmerztherapie von Kindern eine immer wichtigere Rolle.

DYSF mutations lead to a wide range of muscular phenotypes, with the most prominent being Miyoshi myopathy (MM) and limb girdle muscular dystrophy type 2B (LGMD2B). Methods: We assessed the one-year-natural course of dysferlinopathy, and the safety and efficacy of deflazacort treatment in a double-blind, placebo-controlled cross-over trial. After one year of natural course without intervention, 25 patients with genetically defined dysferlinopathy were randomized to receive deflazacort and placebo for six months each (1 mg/kg/day in month one, 1 mg/kg every 2nd day during months two to six) in one of two treatment sequences. Results: During one year of natural course, muscle strength declined about 2\% as measured by CIDD (Clinical Investigation of Duchenne Dystrophy) score, and 76 Newton as measured by hand-held dynamometry. Deflazacort did not improve muscle strength. In contrast, there is a trend of worsening muscle strength under deflazacort treatment, which recovers after discontinuation of the study drug. During deflazacort treatment, patients showed a broad spectrum of steroid side effects. Conclusion: Deflazacort is not an effective therapy for dysferlinopathies, and off-label use is not warranted. This is an important finding, since steroid treatment should not be administered in patients with dysferlinopathy, who may be often misdiagnosed as polymyositis.}, language = {en} } @phdthesis{Fekete2018, author = {Fekete, Stefanie}, title = {Therapeutisches Drug Monitoring (TDM) von Kindern und Jugendlichen unter Behandlung mit Tiaprid : eine prospektive naturalistische Beobachtungsstudie}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-173085}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2018}, abstract = {Tiaprid wird bei Kindern und Jugendlichen im deutschsprachigen Raum als Mittel der ersten Wahl zur Behandlung von Ticst{\"o}rungen off-label eingesetzt.

Therapeutische Referenzbereiche f{\"u}r Tiaprid sind bisher jedoch nur f{\"u}r erwachsene Patienten mit Chorea Huntington definiert worden (1000 bis 2000 ng/ml) (Hiemke et al., 2011). An ausgew{\"a}hlten Zentren im Rahmen des Kompetenznetzwerks Therapeutisches Drug Monitoring Kinder- und Jugendpsychiatrie (www.tdm-kjp.com) wurden von 2007 bis 2014 standardisiert TDM-Daten erfasst, um den Zusammenhang zwischen Dosis, Serumkonzentration, Wirksamkeit und UAW von Tiaprid zu untersuchen sowie Hinweise auf einen m{\"o}glichen alters- und diagnosespezifischen therapeutischen Referenzbereich zu generieren.

Knowledge on dose-concentration relationships of risperidone treatment in children and adolescents with schizophrenia or other psychotic disorders is, however, scarce and no age-specific therapeutic ranges have been established yet. Multicenter data of a therapeutic drug monitoring service were analyzed to evaluate the relationship between risperidone dose and serum concentration of the active moiety (risperidone (RIS) plus its main metabolite 9-hydroxyrisperidone (9-OH-RIS)) in children and adolescents with psychotic disorders. Patient characteristics, doses, serum concentrations and therapeutic outcomes were assessed by standardized measures. The study also aimed to evaluate whether the therapeutic reference range for adults (20-60 ng/ml) is applicable for minors. In the 64 patients (aged 11-18 years) included, a positive correlation between daily dose and the active moiety (RIS\(_{am}\)) concentration was found (r\(_s\) = 0.49, p = 0.001) with variation in dose explaining 24\% (r\(_s\)\(^2\) = 0.240) of the variability in serum concentrations. While the RIS\(_{am}\) concentration showed no difference, RIS as well 9-OH-RIS concentrations and the parent to metabolite ratio varied significantly in patients with co-medication of a CYP2D6 inhibitor. Patients with extrapyramidal symptoms (EPS) had on average higher RIS\(_{am}\) concentrations than patients without (p = 0.05). Considering EPS, the upper threshold of the therapeutic range of RIS\(_{am}\) was determined to be 33 ng/ml. A rough estimation method also indicated a possibly decreased lower limit of the preliminary therapeutic range in minors compared to adults.

Other countries have already adopted additional childhood influenza immunisation programmes. The objective of this study is to determine the potential epidemiological impact of implementing paediatric influenza vaccination using intranasally administered live-attenuated influenza vaccine (LAIV) in Germany. Methods: A deterministic age-structured model is used to simulate the population-level impact of different vaccination strategies on the transmission dynamics of seasonal influenza in Germany. In our base-case analysis, we estimate the effects of adding a LAIV-based immunisation programme targeting children 2 to 17 years of age to the existing influenza vaccination policy. The data used in the model is based on published evidence complemented by expert opinion. Results: In our model, additional vaccination of children 2 to 17 years of age with LAIV leads to the prevention of 23.9 million influenza infections and nearly 16 million symptomatic influenza cases within 10 years. This reduction in burden of disease is not restricted to children. About one third of all adult cases can indirectly be prevented by LAIV immunisation of children. Conclusions: Our results demonstrate that vaccinating children 2-17 years of age is likely associated with a significant reduction in the burden of paediatric influenza. Furthermore, annual routine childhood vaccination against seasonal influenza is expected to decrease the incidence of influenza among adults and older people due to indirect effects of herd protection.

Children were assessed with a 3-loudspeaker setup (front, left and right) at 0.9 years (interval I) and 1.6 years (interval II) after the second implantation, and after 5.3 years of bilateral implant use (interval III) with a 9-loudspeaker setup in the frontal horizontal plane between -90° and 90° azimuth.

Methods Systemic chemotherapeutic treatment of 138 patients enrolled in the German HIT-REZ-studies was analyzed. Survival depending on the use of chemotherapy, disease-stabilization rates (RR), duration of response (DOR) and time to progression (TTP) were estimated. Results Median age at first recurrence was 7.6 years (IQR: 4.0-13.6). At first recurrence, median PFS and OS were 15.3 (CI 13.3-20.0) and 36.9 months (CI 29.7-53.4), respectively. The Hazard Ratio for the use of chemotherapy in local recurrences in a time-dependent Cox-regression analysis was 0.99 (CI 0.74-1.33). Evaluable responses for 140 applied chemotherapies were analyzed, of which sirolimus showed the best RR (50\%) and longest median TTP [11.51 (CI 3.98; 14.0) months] in nine patients, with the strongest impact found when sirolimus was used as a monotherapy. Seven patients with progression-free survival > 12 months after subtotal/no-resection facilitated by chemotherapy were found. No definitive survival advantage for any drug in a specific molecularly defined EPN type was found. Conclusion No survival advantage for the general use of chemotherapy in recurrent EPN was found.
