Poranění podkolenní tepny u 12leté pacientky, zraněné ve válečném konfliktu na Ukrajině, se navzdory zdánlivě chudé symptomatice a absenci subjektivních těžkostí ukázalo jako závažné, vyžadující operační řešení. Netypická byla prezentace arteriálního poranění bez akutní končetinové ischémie. Klinický obraz dolní končetiny ve smyslu pulseless pink na základě tepenní léze sice není častý, ale jeho podcenění může mít pro pacienta trvalé následky.
A popliteal artery injury in a 12-year-old female patient, injured in the war conflict in Ukraine, proved to be serious, requiring surgical treatment, despite seemingly poor symptoms and the absence of subjective difficulties. The presentation of arterial injury without acute limb ischemia was atypical. The clinical picture of the lower limb in the sense of "pulseless pink" based on an arterial lesion is not common, but its underestimation can have permanent consequences for the patient.

Úvod: 3D tisk, koncept starý přes 40 let, nachází díky technologickému pokroku stále širší uplatnění v klinické praxi. Ve FN Ostrava je využíván k vytváření anatomických modelů konkrétních pacientů před chirurgickými výkony na základě dat ze zobrazovacích vyšetření. Kazuistiky: 3D tisk nachází uplatnění jako doplněk ke konvenčním zobrazovacím metodám s cílem zhotovit morfologicky přesné modely anatomických struktur konkrétních pacientů. Tyto modely slouží především pro předoperační přípravu v elektivní břišní, cévní a hrudní chirurgii. Využívají se rovněž při plánování osteosyntéz složitých zlomenin a korekčních osteotomií. Vícebarevný tisk, přestože zvyšuje časovou náročnost procesu, umožňuje lepší přehlednost a diferenciaci jednotlivých anatomických struktur v rámci jednoho modelu. Diskuze: 3D modely poskytují lepší prostorovou orientaci a rozpoznání operovaných struktur než 2D obrazy, což přispívá k lepším výsledkům zákroků. Jejich přínos je potvrzen studiemi napříč obory, od kardiochirurgie po traumatologii. Závěr: Po odstranění počátečních překážek se 3D tisk stal spolehlivou součástí arzenálu Chirurgické kliniky FN Ostrava pro elektivní chirurgii. I když 3D tisk nepředstavuje univerzální odpověď na všechny výzvy, kterým v medicíně čelíme, jeho role je v řadě indikovaných případů velmi přínosná a perspektivní.
Introduction: 3D printing, a concept over 40 years old, is finding broader application in clinical practice thanks to technological advancements. At University Hospital Ostrava, 3D printing is utilized to create anatomically accurate models of specific patients before surgical procedures based on imaging data. Case series: 3D printing is employed as a complement to conventional imaging methods to produce morphologically precise models of anatomical structures of individual patients. These models primarily serve for preoperative planning in elective abdominal, vascular, and thoracic surgery. They are also used in planning osteosynthesis of complex fractures and corrective osteotomies. Multicolor printing, although increasing the process‘s time demands, allows better clarity and differentiation of individual anatomical structures within a single model. Discussion: Compared to 2D images, 3D models provide better spatial orientation and awareness of the operated structures, contributing to improved surgical outcomes. The benefits of 3D printing in preoperative planning and patient education are confirmed by studies across the fields ranging from cardiac surgery to traumatology. Conclusion: After overcoming initial challenges, 3D printing has become a reliable component of the surgical arsenal at University Hospital Ostrava for elective surgery. While 3D printing does not represent a universal answer to all medical challenges, its role is highly beneficial and promising in many indicated cases.
Background and Objectives: Surgical site infections (SSIs) are a significant complication following ventral hernia repair, potentially leading to prolonged hospital stays and increased morbidity. This study aimed to evaluate whether closed incision negative pressure wound therapy (ciNPWT) reduces the incidence of SSI after ventral hernia repair with polypropylene mesh compared to standard wound care. Materials and Methods: A randomized study was conducted with 100 patients undergoing ventral hernia repair using a polypropylene mesh. Participants were divided into two groups: a control group (n=50), which received standard sterile gauze dressing with an iodine-based disinfectant, and an intervention group (n=50), treated with the ciNPWT system (Vivano® by HARTMANN) for 5 days postoperatively. The primary outcome was the incidence of SSI within one year after surgery. Secondary outcomes included the influence of factors such as age, sex, smoking status, and hernia size on SSI occurrence. The study was approved by the Ethics Committee at the University Hospital Ostrava, adhering to the ethical standards of the Helsinki Declaration. Results: The incidence of SSI was lower in the ciNPWT group compared to the standard care group (4% vs. 12%), though this difference did not reach statistical significance. No significant effect of sex or smoking status on SSI was observed. The control group had a shorter mean length of hospital stay. Larger hernias in the non-ciNPWT group were more prone to SSIs, as expected. Conclusions: Although limited by a small sample size, the findings suggest that ciNPWT may be associated with a reduced rate of SSI following ventral hernia repair. Further studies with larger populations are needed to confirm these results.

The analysis of biomedical signals is a very challenging task. This review paper is focused on the presentation of various methods where biomedical data, in particular vital signs, could be monitored using sensors mounted to beds. The presented methods to monitor vital signs include those combined with optical fibers, camera systems, pressure sensors, or other sensors, which may provide more efficient patient bed monitoring results. This work also covers the aspects of interference occurrence in the above-mentioned signals and sleep quality monitoring, which play a very important role in the analysis of biomedical signals and the choice of appropriate signal-processing methods. The provided information will help various researchers to understand the importance of vital sign monitoring and will be a thorough and up-to-date summary of these methods. It will also be a foundation for further enhancement of these methods.
In the Czech part of the Upper Silesian Coal Basin (Moravian-Silesian region, Czech Republic), there are many deposits of endogenous combustion (e.g., localized burning soil bodies, landfills containing industrial waste, or slag rocks caused by mining processes). The Hedwig mining dump represents such an example of these sites where, besides the temperature and the concentrations of toxic gases, electric and non-electric quantities are also monitored within the frame of experimentally proposed and patented technology for heat collection (the so-called "Pershing" system). Based on these quantities, this paper deals with the determination and evaluation of negative heat sources and the optimization of the positive heat source dependent on measured temperatures within evaluation points or on a thermal profile. The optimization problem is defined based on a balance of the heat sources in the steady state while searching for a local minimum of the objective function for the heat source. From an implementation point of view, it is the interconnection of the numerical model of the heat collector in COMSOL with a user optimization algorithm in MATLAB using the LiveLink for MATLAB. The results are elaborated in five case studies based on the susceptibility testing of the numerical model by input data from the evaluation points. The tests were focused on the model behavior in terms of preprocessing for measurement data from each chamber of the heat collector and for the estimated value of temperature differences at 90% and 110% of the nominal value. It turned out that the numerical model is more sensitive to the estimates in comparison with the measured data of the chambers, and this finding does not depend on the type optimization algorithm. The validation of the model by the use of the mean-square error led to the finding of optimal value, also valid with respect to the other evaluation.

Many different investments háve gone into hospital information systems worldwide. When those systems are evaluated, most of them do not meet clinicians' needs. To address the shortcomings EuroMISE Centre has developed an electronic health record (EHR) application MUDRLite, which can be customized to needs of a particular health care provider. To address the shortcomings especially in dental medicíně we háve brought together a unique cross-disciplinary collaborative group of computer scientists, statisticians, software developers, and clinicians, from the Department of Medical Informatics, Institute of Computer Science, Academy of Sciences of the Czech Republic and the Department of Prosthodontics of the Charles University in Prague, lst Medical Faculty, to collaborate on research and development with the prevailing goal of providing consistency in electronic recording, archiving, analyzing and disseminating of dental medicíně data. A highly-advanced MUDRLite component implementing the interactive dental cross represents one of the results of the joined effort. The data model of this component originates in a technology called "Dental Medicíně Data Structuring Technology Using a Dental Cross". This technology was enrolled as a patent application form under the No. PV 2005-229. Using the dental cross component a dentist can choose among about 60 different actions, treatment procedu-res or dental parameters that are displayed lucidly on the screen. The components support typical clinical workf-lows including treatment of primary and secondary caries, fillings, pulp pathology etc. It combines a treatment pian with an interactive calendar that enables to schedule patients' visits and treatments. The interactive dental cross analysis was prepared in a form of a čase report. Information record in a graphic structure accelerates dentisťs decision-making and it enables a more complex view while suggesting a treatment pian.
