Interdyscyplinarna opieka nad chorymi po zabiegach z zakresu chirurgii szczękowo-twarzowej

Wstęp: Zabiegi z zakresu chirurgii czaszkowo-szczękowo-twarzowej ze względu na swoją specyfikę mogą prowadzić do znacznych upośledzeń czynnościowych. Zniekształcenia pooperacyjne i pourazowe twarzy oraz wady ortognatyczne zaburzają estetykę i harmonię rysów twarzy, utrudniając choremu wyrażanie emocji i porozumiewanie się z otoczeniem. Dlatego priorytetem jest interdyscyplinarna opieka przedi pooperacyjna. Zespół lekarzy, fizjoterapeutów, logopedów, foniatrów, dietetyków oraz psychologów ma przywrócić pacjenta do życia w społeczeństwie w zakresie najbardziej zbliżonym do tego sprzed choroby. Materiał i metody: Badaniem objęto 132 pacjentów Przyklinicznego Zespołu Rehabilitacyjnego Kliniki Chirurgii Czaszkowo-Szczękowo-Twarzowej SUM w Katowicach w latach 2020–2022. Wiek chorych wahał się w zakresie 20–70 lat, średnia wieku wynosiła 44,02. Wśród badanych osób było 71 kobiet (53,8%); 45,5% pacjentów stanowiły osoby po urazach twarzoczaszki, 20,5% osoby z dysfunkcjami stawów skroniowo-żuchwowych, 18,9% chorzy onkologiczni, a 15,2% pacjenci z innymi schorzeniami. Chorzy poddani zabiegom uczestniczyli w rehabilitacji przed- i pooperacyjnej, która odbywała się w trakcie hospitalizacji oraz ambulatoryjnie. Wykonywano zabiegi rehabilitacyjne z zakresu nowoczesnej terapii ruchowej, terapii oddechowej, manualnego drenażu limfatycznego, manualnej terapii mięśniowo-powięziowej oraz procedury wspomagające, jak: suche igłowanie, kinesiotaping i techniki fizjoterapeutyczne. Pacjenci korzystali dodatkowo z pomocy dietetyka, psychologa oraz logopedy. Wyniki: Skuteczność przeprowadzonej rehabilitacji uzyskano w około 90% w zakresie zmniejszenia obrzęku, terapii blizn oraz w działaniu przeciwbólowym. Wzrost odwodzenia żuchwy notowano u 79,2% pacjentów. Porównanie pacjentów po przebytym urazie twarzoczaszki i z nowotworem tej okolicy wskazuje na uzyskanie gorszych wyników u pacjentów onkologicznych oraz występowanie u nich dodatkowych problemów z mową i oddychaniem. Wnioski: Wielospecjalistyczna terapia jest nieodłącznym elementem uzupełniającym leczenie chirurgiczne. Uzyskane wyniki wskazują na potrzebę przeprowadzenia dalszych badań klinicznych na poszczególnych grupach chorych, aby dać możliwość opracowania algorytmów interdyscyplinarnego postępowania z chorym na oddziale chirurgii szczękowo-twarzowej

Analysis procedure of the positronium lifetime spectra for the J-PET detector

Positron Annihilation Lifetime Spectroscopy (PALS) has shown to be a powerful tool to study the nanostructures of porous materials. Positron Emissions Tomography (PET) are devices allowing imaging of metabolic processes e.g. in human bodies. A newly developed device, the J-PET (Jagiellonian PET), will allow PALS in addition to imaging, thus combining both analyses providing new methods for physics and medicine. In this contribution we present a computer program that is compatible with the J-PET software. We compare its performance with the standard program LT 9.0 by using PALS data from hexane measurements at different temperatures. Our program is based on an iterative procedure, and our fits prove that it performs as good as LT 9.0.Comment: 4 figures, 8 page

Overview of the software architecture and data flow for the J-PET tomography device

Modern TOF-PET scanner systems require high-speed computing resources for efficient data processing, monitoring and image reconstruction. In this article, we present the data flow and software architecture for the novel TOF-PET scanner developed by the J-PET Collaboration. We discuss the data acquisition system, reconstruction framework and image reconstruction software. Also, the concept of computing outside hospitals in the remote centers such as Świerk Computing Centre in Poland is presented

Multiple scattering and accidental coincidences in the J-PET detector simulated using GATE package

Novel Positron Emission Tomography system, based on plastic scintillators, is developed by the J-PET collaboration. In order to optimize geometrical configuration of built device, advanced computer simulations are performed. Detailed study is presented of background given by accidental coincidences and multiple scattering of gamma quanta

Sampling FEE and trigger-less DAQ for the J-PET scanner

In this paper, we present a complete Data Acquisition System (DAQ) together with the readout mechanisms for the J-PET tomography scanner. In general, detector readout chain is constructed out of Front-End Electronics (FEE) measurement devices such as Time-to-Digital or Analog-to-Digital Converters (TDCs or ADCs), data collectors and storage. We have developed a system capable for maintaining continuous readout of digitized data without preliminary selection. Such operation mode results in up to 8 Gbps data stream, therefore, it is required to introduce a dedicated module for on-line event building and feature extraction. The Central Controller Module, equipped with Xilinx Zynq SoC and 16 optical transceivers, serves as such true real time computing facility. Our solution for the continuous data recording (trigger-less) is a novel approach in such detector systems and assures that most of the information is preserved on the storage for further, high-level processing. Signal discrimination applies a unique method of using LVDS buffers located in the FPGA fabric

Introduction of total variation regularization into filtered backprojection algorithm

In this paper we extend the state-of-the-art filtered backprojection (FBP) method with application of the concept of Total Variation regularization. We compare the performance of the new algorithm with the most common form of regularizing in the FBP image reconstruction via apodizing functions. The methods are validated in terms of cross-correlation coefficient between reconstructed and real image of radioactive tracer distribution using standard Derenzo-type phantom. We demonstrate that the proposed approach results in higher cross-correlation values with respect to the standard FBP method

A method to produce linearly polarized positrons and positronium atoms with the J-PET detector

A method for creating linearly polarized positrons and ortho-positronium (o-Ps) atoms with the J-PET detector is presented. The unique geometry and properties of the J-PET tomography enable one to design a positron source such that the quantization axis for the estimation of the linear polarization of produced o-Ps can be determined on the event by event basis in a direction of the positron motion. We intend to use ²²Na or other β⁺ decay isotopes as a source of polarized positrons. Due to the parity violation in the beta decay, the emitted positrons are longitudinally polarized. The choice of the quantization axis is based on the known position of the positron emitter and the reconstructed position of the positronium annihilation. We show that the J-PET tomography is equipped with all needed components

Time calibration of the J-PET detector

The Jagiellonian Positron Emission Tomograph (J-PET) project carried out in the Institute of Physics of the Jagiellonian University is focused on construction and tests of the first prototype of PET scanner for medical diagnostic which allows for the simultaneous 3D imaging of the whole human body using organic scintillators. The J-PET prototype consists of 192 scintillator strips forming three cylindrical layers which are optimized for the detection of photons from the electron-positron annihilation with high time- and high angular-resolutions. In this article we present time calibration and synchronization of the whole J-PET detection system by irradiating each single detection module with a 22Na source and a small detector providing common reference time for synchronization of all the modules

Preliminary studies of J-PET detector spatial resolution

The J-PET detector, based on long plastic scintillator strips, was recently constructed at the Jagiellonian University. It consists of 192 modules axially arranged into three layers, read out from both sides by digital constant-threshold front-end electronics. This work presents preliminary results of measurements of the spatial resolution of the J-PET tomograph performed with ²²Na source placed at selected position inside the detector chamber

Evaluation of the Acute Oral Toxicity Class of Trinuclear Chromium(III) Glycinate Complex in Rat

Chromium(III) is considered as an essential element playing a role in carbohydrate and lipid metabolism, and various chemical forms of this element are widely used in dietary supplements. A new trinuclear chromium(III) glycinate complex [Cr3O(NH2CH2CO2)6(H2O)3]+NO3− (CrGly), an analogue of Cr3 (trinuclear Cr(III) propionate complex) has been synthesized as a potential source of supplementary Cr. In this study, we evaluated the acute toxicity class of CrGly in Wistar rats applying the OECD 423 procedure. Male and female Wistar rats (n = 12, 6 ♀ and 6 ♂) were given by gavage either a single dose of CrGly 2,000 mg/kg body mass (equals to 300 mg Cr(III)/kg body mass; in aqueous solution) or equivalent volumes of distilled water and fed ad libitum commercial Labofeed B diet, and observed carefully for 14 days, then sacrificed to collect blood and internal organs for biochemical and histologic examination. No death cases were detected. No abnormalities in animal behavior, body mass gains, gross organ histology, or blood morphology and biochemistry were observed. The results demonstrate that LD50 of CrGly is greater than 2,000 mg/kg when administrated orally to rat; thus, this compound appears to belong to the fifth category in the GHS system or the fourth class (“unclassified”) in the EU classification system
