Autoři prezentují mezioborové řešení vrozené končetinové vady levé ruky a pravé dolní končetiny u jinak zdravého batolete, a to ortopedicko-chirurgické léčení centrální polysyndaktylie s flekční kontrakturou PIP kloubu 2. a 3. prstu (operace ve 13 měs.) a ortopedicko- protetické ošetření po exartikulaci v pravém kolenním kloubu pro tibiální aplazii (typ IA podle Jonese et al., 1978) v 16 měsících věku. Tato longitudinální vrozená vada dolní končetiny vylučuje zátěž končetiny při chůzi, a to i pokud by byla k vybavení použita individuálně zhotovená nosná ortéza (tzv. ortoprotéza). Výkon umožnil vytvořit stehenní amputační pahýl, který toleruje plnou zátěž při stoji a chůzi batolete. Po vybavení protézou dolní končetiny se rychle rozvinula pohybová aktivita dítěte, které ihned začalo pravou dolní končetinu v protéze plně zatěžovat. Protéza se pro chlapce stala zcela samozřejmou a nezbytnou součástí. Kazuistika upozorňuje na nezbytnou spolupráci mezi ortopedickým a protetickým pracovištěm v oblasti řešení problematiky vrozených vad pohybového aparátu. Sdělení ukazuje specifika chirurgického řešení biomechanicky závažných vrozených vad horních a dolních končetin a základní principy protetického vybavení dolních končetin u dětí.
The authors present interdisciplinary solution of the congenital left hand defect and the tibial aplasia of the right lower extremity in a healthy toddler. The case report is concerned about orthopaedic surgery of the central polysyndactyly of 2nd and 3rd finger (surgery in 13 months of age) and orthopaedic prosthetic fitting after amputation (in 16 months of age) at the level of the knee joint due to deficiency of the tibia (type IA). This longitudinal defect of the lower extremity debar the leg from loading in standing and walking even when the toddler would be fitted by individual orthosis. Amputation (disarticulation) facilitated to form a stump that enough tolerate full load by standing and walking. After prosthetic fitting the movement activity of the toddler promptly developed and he immediately began to load his right leg in prosthesis. Prosthesis became self-evident and requisite component of the small boy. The case report alerts to needful cooperation between orthopaedic and orthopaedic prosthetic department in area of the congenital locomotor defects problems. This communication shows particularities of surgical solution of biomechanically severe congenital limb defects and the main principles of prosthetic fittings of lower extremities in children.

In this chapter, we demonstrate the advantage of the simultaneous multicurve nonlinear least-squares analysis over that of the conventional single-curve analysis. Fitting results are subjected to thorough Monte Carlo analysis for rigorous assessment of confidence intervals and parameter correlations. The comparison is performed on a practical example of simulated steady-state reaction kinetics complemented with isothermal calorimetry (ITC) data resembling allosteric behavior of rabbit muscle pyruvate kinase (RMPK). Global analysis improves accuracy and confidence limits of model parameters. Cross-correlation between parameters is also reduced with accompanying enhancement of the model-testing power. This becomes especially important for validation of models with "difficult" highly cross-correlated parameters. We show how proper experimental design and critical evaluation of data can improve the chance of differentiating models.

The susceptible-infected-removed (SIR) and the susceptible-exposed-infected-removed (SEIR) epidemic models with constant parameters are adequate for describing the time evolution of seasonal diseases for which available data usually consist of fatality reports. The problems associated with the determination of system parameters starts with the inference of the number of removed individuals from fatality data, because the infection to death period may depend on health care factors. Then, one encounters numerical sensitivity problems for the determination of the system parameters from a correct but noisy representative of the number of removed individuals. Finally as the available data is necessarily a normalized one, the models fitting this data may not be unique. We prove that the parameters of the (SEIR) model cannot be determined from the knowledge of a normalized curve of "Removed" individuals and we show that the proportion of removed individuals, [Formula: see text], is invariant under the interchange of the incubation and infection periods and corresponding scalings of the contact rate. On the other hand we prove that the SIR model fitting a normalized curve of removed individuals is unique and we give an implicit relation for the system parameters in terms of the values of [Formula: see text] and [Formula: see text], where [Formula: see text] is the steady state value of [Formula: see text] and [Formula: see text] and [Formula: see text] are the values of [Formula: see text] and its derivative at the inflection point [Formula: see text] of [Formula: see text]. We use these implicit relations to provide a robust method for the estimation of the system parameters and we apply this procedure to the fatality data for the H1N1 epidemic in the Czech Republic during 2009. We finally discuss the inference of the number of removed individuals from observational data, using a clinical survey conducted at major hospitals in Istanbul, Turkey, during 2009 H1N1 epidemic.

The study deals with the process of estimation of material parameters from uniaxial test data of arterial tissue and focuses on the role of transverse strains. Two fitting strategies are analyzed and their impact on the predictive and descriptive capabilities of the resulting model is evaluated. The standard fitting procedure (strategy A) based on longitudinal stress-strain curves is compared with the enhanced approach (strategy B) taking also the transverse strain test data into account. The study is performed on a large set of material data adopted from literature and for a variety of constitutive models developed for fibrous soft tissues. The standard procedure (A) ignoring the transverse strain test data is found rather hazardous, leading often to unrealistic predictions of the model exhibiting auxetic behaviour. In contrast, the alternative fitting method (B) ensures a realistic strain response of the model and is proved to be superior since it does not require any significant demands of computational effort or additional testing. The results presented in this paper show that even the artificial transverse strain data (i.e., not measured during testing but generated ex post based on assumed Poisson's ratio) are much less hazardous than total disregard of the transverse strain response.
