Authors: Suciu B.A. , Bud V. , Milutin Doina , Halmaciu Ioana , Constantin C. , Brinzaniuc Klara
Published: May 2015

Gastrointestinal stromal tumors are an uncommon sarcomas with mesenchymal origin that arises in the gastrointestinal tract. Recently, most of the published reports describe such tumors located outside of the gastrointestinal tract, with similar pathological characteristics and are named extra-gastrointestinal stromal tumors. We report the case of a patient suffering for a giant retroperitoneal extra-gastrointestinal stromal tumor, complicated with intra-tumoral hemorrhage. The particularity of this case is the presence of the intra-tumoral hemorrhage in a retroperitoneal extragastrointestinal stromal tumor that grew rapidly in volume (in 1 week).

Authors: Popa Oana , Bordei P. , Ionescu C. , Iliescu D.M.
Published: May 2015

The diameter at the origin of the internal iliac vein was found between 4.7 to 9.9 mm; for the right internal iliac vein between 4.7 to 9.7 mm; the statistical distribution groups value in ascending order being as follows: 4.7 to 5.5 mm: 4 cases (22.22% of cases); 6.9 to 7.8 mm: 6 cases (33.33% of cases); 8.4-8.8 mm: 4 cases (22.22% of cases); 9.1 to 9.7 mm: 4 cases (22.22% of cases). The diameter at the origin of the left internal iliac vein was between 4.8 to 9.9 mm, while the distribution statistics on groups of values, in ascending order, being as follows: 4.8-5.2 mm: 4 cases (22.22 % of cases); 6.8-7.1 mm: 8 cases (44.44% of cases); 8.3 to 9.9 mm: 6 cases (33.33% of cases). The diameter at the end of the internal iliac vein was between 5.9 to 10.2 mm; the diameter at the end of the right internal iliac vein was between 6.1 to 10.2 mm, the statistical distribution of values groups in ascending order being follows: 6.1 to 7.5 mm: 6 cases (33.33% of cases); 8.4 to 8.7 mm: 8 cases (44.44% of cases); 9.3 to 10.2 mm: 4 cases (22.22% of cases). The diameter at the end of the left internal iliac vein was between 5.9 to 9.9 mm, while the distribution statistics on groups of values in ascending order being as follows: 5.9 to 6.2 mm: 4 cases (22.22 % of cases); 7 to 7.6 mm: 3 cases (16.67% of cases); 8.3-8.4 mm: 5 cases (27.28% of cases); 9.1 to 9.9 mm: 6 cases (33.33% of cases). Comparing the common iliac vein caliber of the two, right and left, we found that in 10 cases (55.56% of cases), the right internal iliac vein has a greater diameter than the left one by 0.3 mm. In 8 cases (44.44% of cases), the left internal iliac vein has a larger diameter than the right one with 0.1-0.6 mm; between the two values there is a difference of 0.5 mm
Morphometric Characterization of Marginal Zone Lymphoma
Authors: Chisoi Anca , Aşchie Mariana , Enciu Manuela
Published: May 2015

The morphometry in histopathology is used to characterize cell populations belonging to different tissues and to identify differences in their parameters with prognostic implications. To achieve morphometric examination were selected 6 of 8 cases identified as marginal zone lymphoma. For each case analysis was done on five fields, for each field measuring the parameters of 20 cells. The studied parameters were for cytoplasm: cytoplasmic area, maximum and minimum cytoplasmic diameter, cytoplasmic perimeter; for nucleus were measured: nuclear area, minimum and maximum nuclear diameter, nuclear perimeter, nuclear contour index, nuclear ellipticity index, nuclear irregularity index. Also the nucleo-cytoplasmic ratio was calculated in all studied cases. Marginal zone lymphoma is characterized in terms of morphometric parameters by small cytoplasmic and nuclear area, and small nucleo-cytoplasmatic ratio of about 1:1. Nuclear contour index is small, accompanied by a large ellipticity index and an small index of nuclear irregularity. Standard deviations for measured morphometric parameters are variable, having high values for cytoplasmic and nuclear area, highlighting the polymorphic nature of the cells. Morphometric aspects, with corresponding microscopic aspects of large and small lymphocyte proliferation with cleaved and uncleaved nuclei, fit this form of lymphoma in terms of clinical outcome in indolent lymphomas category.

Published: May 2015

Basaloid squamous cell carcinoma is a rare variant of squamous cell carcinoma that most often occurs in the upper aerodigestive tract. This type of tumor has an aggressive behavior and usually is diagnosed in the advances stage. The diagnosis of basaloid squamous cell carcinoma is rather difficult and is based on histopathological and immunohistochemical examination. We report a case of laryngeal basaloid squamous cell carcinoma diagnosed by histological examination of a excisional biopsy specimen. The patient was a 57-year old female with a 3 months-history hoarseness and odynophagia. The histopathological aspect was strongly suggestive for BSCC. Immunohistochemical examination has been done using a panel of biomarkers in order to confirm our initial diagnose. The tumors nests were positive for squamous epithelial marker citokeratin 34βE12, AE1/AE3, CK 19 and also p53 and negative for carcinoembryonic antigen (CEA), vimentin and for neuroendocrine markers. Ki- 67 marker was positive in 60% of the tumoral cells. Based on histopathological and immunohistochemical findings, the tumor was diagnosed as basaloid squamous cell carcinoma.

Authors: Maiorean Alexandra , Aşchie Mariana , Mitroi Anca Florentina , Poinareanu I.
Published: May 2015

Crohn’s disease is an idiopathic inflammatory disorder which can affect any segment of the digestive tract. Generally considered uncommon and often underestimated, it can endanger the patient’s life due to its local and systemic complications. In this article we present the case of a 67-year-old male patient who was admitted for cramping abdominal pain, nonbloody diarrhea, fever and anorexia. He described a 5-year history of similar episodes composed of the same symptoms for which he was admitted. In the past no diagnosis was confirmed and he received no treatment, due to the fact that the episodes were autolimited and the patient didn’t ask for medical attention. In this case surgery was required and the diagnosis of Crohn’s disease was histopathologically confirmed, thus leading to a proper choice of treatment to avoid possible complications.

Authors: Dumitru Irina Magdalena , Cernat Roxana Carmen , Rugină S.
Published: May 2015

In the past years there have been numerous discoveries regarding treatment of patients with HIV. If at first the doctors watched as patients live longer, now we want these patients to live better with regimens potent, safe, individualized and without side effects. HAART has revolutionized “the world HIV” and caused a significant reduction in mortality, and morbidity associated with HIV-related opportunistic infections. However, side effects associated with HAART, metabolic toxicity (such as abnormal fat distribution, abnormal lipid and glucose metabolism, and bone loss) and the large number of pills led to decreased patient adherence.
Statistical Control Charts: Performances of Short Term Stock Trading in Croatia
Authors: Dumičić Ksenija , Žmuk Berislav
Published: May 2015

Background: The stock exchange, as a regulated financial market, in modern economies reflects their economic development level. The stock market indicates the mood of investors in the development of a country and is an important ingredient for growth. Objectives: This paper aims to introduce an additional statistical tool used to support the decision-making process in stock trading, and it investigate the usage of statistical process control (SPC) methods into the stock trading process. Methods/Approach: The individual (I), exponentially weighted moving average (EWMA) and cumulative sum (CUSUM) control charts were used for gaining trade signals. The open and the average prices of CROBEX10 index stocks on the Zagreb Stock Exchange were used in the analysis. The statistical control charts capabilities for stock trading in the short-run were analysed. Results: The statistical control chart analysis pointed out too many signals to buy or sell stocks. Most of them are considered as false alarms. So, the statistical control charts showed to be not so much useful in stock trading or in a portfolio analysis. Conclusions: The presence of non-normality and autocorellation has great impact on statistical control charts performances. It is assumed that if these two problems are solved, the use of statistical control charts in a portfolio analysis could be greatly improved.
A Comparative Analysis of Value at Risk Measurement on Emerging Stock Markets: Case of Montenegro
Authors: Cerović Julija , Lipovina-Božović Milena , Vujošević Saša
Published: May 2015

Background: The concept of value at risk gives estimation of the maximum loss of financial position at a given time for a given probability. The motivation for this analysis lies in the desire to devote necessary attention to risks in Montenegro, and to approach to quantifying and managing risk more thoroughly. Objectives: This paper considers adequacy of the most recent approaches for quantifying market risk, especially of methods that are in the basis of extreme value theory, in Montenegrin emerging market before and during the global financial crisis. In particular, the purpose of the paper is to investigate whether extreme value theory outperforms econometric and quantile evaluation of VaR in emerging stock markets such as Montenegrin market. Methods/Approach: Daily return of Montenegrin stock market index MONEX20 is analyzed for the period January, 2004 - February, 2014. Value at Risk results based on GARCH models, quantile estimation and extreme value theory are compared. Results: Results of the empirical analysis show that the assessments of Value at Risk based on extreme value theory outperform econometric and quantile evaluations. Conclusions: It is obvious that econometric evaluations (ARMA(2,0)- GARCH(1,1) and RiskMetrics) proved to be on the lower bound of possible Value at Risk movements. Risk estimation on emerging markets can be focused on methodology using extreme value theory that is more sophisticated as it has been proven to be the most cautious model when dealing with turbulent times and financial turmoil.
The Impact of the Great Recession on Monetary and Fiscal Policy in Developed Market Economies
Authors: Šehović Damir
Published: May 2015

Background: With the occurrence of the crisis in 2007, which caused the largest economic contraction since the Great Depression in the thirties, it has become evident that the previous understanding of strategies, effects and roles of monetary and fiscal policy should be redefined. Objectives: The aim of this paper is to illustrate a possible expected change in monetary and fiscal policy in developed market economies that could occur as a consequence of the Great Recession. Methods/Approach: The paper provides a comparative analysis of various primary economic variables related to the developed OECD countries, as well as the empirical testing of the selected theoretical assumptions. Results: The changes in monetary policy refer to the question of raising target inflation, considering a possible use of aggregate price level targeting and paying attention to the role of central banks in suppressing the formation of an asset bubble. The success of fiscal policy in attaining stabilization depends on the size of possible fiscal measures and creation of automatic stabilizers. Conclusions: For the most part, monetary and fiscal policies will still stay unchanged, although some segments of these policies need to be improved.
Acquiring topic structures in Mandarin Chinese
Authors: Liu Feng-hsi
Published: May 2015

Previous studies suggest that Chinese topic structures, especially base-generated structures, are difficult for L1 English L2 Chinese learners, and only at the very advanced stage do learners perform at the target-like level. Yuan (1995) hypothesizes that non-advanced L2 learners may have difficulty adding a topic node to the subject-predicate structure and that they tend to interpret the topic as the subject. The present study tests this hypothesis and seeks to find out if structure building is accessible to L2 learners before they reach an advanced stage. A grammatical judgment experiment was conducted on several types of topic structures. Results show that lower-level subjects behaved on a par with native speakers on certain types of topic structures. This result suggests that L2 learners are able to build new structures at an early stage.

Acquiring Topic Structures in Mandarin Chinese

前人认为汉语的主题结构，尤其是未经过移位产生的基本式结构，对以英语为母语的汉语学习者构成极大困难，只有当学习者达到最高水平时才能掌握。袁（1995）提出假设认为汉语学习者在初，中阶段可能无法在结构上加上主题节点，因此倾向于将句子主题分析为主语。本文针对此一假设进行测试，查看初，中阶汉语学习者是否有能力在主谓结构上加建主题节点。学习者对不同的主题结构进行合法度判断，结果显示对于某些主题结构初阶者的判断和母语为汉语者的判断并无不同。此一结果表示汉语学习者在初阶即有能力在主谓结构上加建结构。
“一 X 就 Y” 格式的句法语义界面

提要

本文探析汉语的 “一X 就 Y” 格式的下位类型区分，分别对其中小类的格式意义作了描写，它们不同的格式意义一方面源自 “一” 与 “就” 的原始意义，另一方面是句法环境作用的结果，格式意义形成以后会影响所组成词汇意义的选择。从类型学的角度看，“一X 就 Y” 格式从时间关系发展为条件关系的动因是句内语义环境从现实转为非现实，它表达规律性语义的句法条件主要有不能带已然标记、以类名词作主语、以时段表示事件时间以及添加条件句标记、认识情态标记和频率标记等，这一格式句法和语义的衔接界面，可构拟一个操作性极强的语义生成流程。
香港南亚少数族裔小学生的汉语阅读和朗读
Authors: Chou Priscilla
Published: May 2015

提要

南亚裔人士移居香港主要缘于英国的百年贸易和殖民地统治。面对南亚裔人口的急剧增加，但南亚裔学生却因汉语能力欠佳而较难升读大学，南亚裔学生的汉语教学遂成为香港当今最重要的教育议题之一 。近年不少学者已明确指出，南亚裔中学生的汉语学习困难以 “写” 为最，“读”次之。但有关香港的南亚裔小学生的汉语学习困难仍然没有定论。本文通过测试、访谈、观课，比较 4 个地区 5 所学校 32 位香港南亚裔小三学生在写作和阅读方面的表现，又透过访谈、观课考查 10 位研究对象的汉语朗读问题。结果发现对于已掌握一定写字能力的学生而言，在阅读方面较写作有更大的 “隐忧”，而朗读由于不是 “听、说、读、写”的日常考试范围，在小学阶段没有“朗读”考试，所以更容易被忽略。文章最后提出一些改善南亚裔学生阅读和朗读表现的建议方法，希望能有效提升第二语言教师对学生这两方面“潜伏”困难的注意力，解决学生在阅读和朗读方面遇上的学习困难。
Quantity quotient reporting. Comparison of various models
Authors: Haeckel Rainer , Wosniok Werner , Postma Theo
Published: May 2015

Quantity quotient (QQ) reporting has been proposed by several authors to improve or support the present situation of presenting quantitative laboratory results. This proposal is based on a concept (symmetrical model) known from the intelligence quotient, which was developed to make intelligence tests comparable. In laboratory medicine, however, most measurands follow a non-symmetrical (skewed) distribution, leading to a compression of the QQ values at the lower end of the reference interval. This effect can be avoided by several alternatives. Three models considering non-symmetrical distributions are compared with the symmetrical model in the present study. The corresponding algorithms can be easily handled on the Excel platform. Graphical presentation of the QQ allows a quick overview of test results if they occur in a large number.

Published: May 2015

Diabetes mellitus is a global pandemic and continues to increase in numbers and significance. Several pathogenic processes are involved in the development of such disease and these mechanisms could be influenced by genetic, epigenetic and environmental factors. Non-enzymatic glycation reactions of proteins have been strongly related to pathogenesis of chronic diabetic complications. The identification of fructosamine 3-kinase (FN3K), an enzyme involved in protein deglycation, a new form of protein repair, is of great interest. FN3K phosphorylates fructosamines on the third carbon of their sugar moiety, making them unstable and causing them to detach from proteins, suggesting a protective role of this enzyme. Moreover, the variability in FN3K activity has been associated with some polymorphisms in the
Neurotrophine-3 may contribute to neuronal differentiation of mesenchymal stem cells through the activation of the bone morphogenetic protein pathway
Authors: Li Lei , Li Yunpeng , Jiang Hongkun
Published: May 2015

We investigated whether neurotrophin-3 (NT-3) can promote differentiation of mouse bone mesenchymal stem cells (MSCs) into neurons via the bone morphogenetic protein pathway. MSCs were prepared from rat bone marrow and either transfected with pIRES2-EGFP or pIRES2-EGFP-NT-3 or treated with bone morphogenetic protein 4. The pIRES2-EGFP-NT-3-transfected MSCs further underwent noggin treatment or siRNA-mediated knockout of the TrkC gene or were left untreated. Immunofluorescence staining, real-time PCR and Western blot analyses were performed to evaluate the transcription and expression of neural-specific genes and BMP-Smad signaling. MSCs were efficiently transduced by the NT-3 gene via pIRES2-EGFP vectors. pIRES2- EGFP-NT-3 could initiate the transcription and expression of neural-specific genes, including nestin, NSE and MAP-2, and stimulate BMP-Smad signaling. The transcription and expression of neural-specific genes and BMP-Smad signaling were significantly suppressed by siRNA-mediated knockdown of the TrkC gene of MSCs. These findings suggest that the BMP signaling pathway may be a key regulatory point in NT-3-transfected neuronal differentiation of MSCs. The BMP and neurotrophin pathways contribute to a tightly regulated signaling network that directs the precise connections between neuronal differentiation of MSCs and their targets.
Non-Intrusive Historical Assessment of Internet-Facing Services in the Internet of Things
Authors: Genge Béla , Enăchescu Călin
Published: May 2015

The expansion of Internet has led to a variety of directly accessible devices and services. Nowadays, companies tend to increase the number of Internetfacing services in order to ensure higher visibility, and accessibility towards end-users. Nonetheless, this profound expansion towards an “Internet of Things” brings new opportunities to malicious actors. As a result, novel cyber-physical attacks bring new challenges to systems administrators in order to accommodate traditional user requests with security prerequisites. Therefore, in this paper we propose a novel approach for historical Internet connectivity assessment of services. The technique uses the output of the popular Shodan search engine to infer the lifetime of different Internet-facing services. Experimental results conducted on IP address blocks attributed to six different institutions distributed across four sectors (university, telecommunications, banking, and power) show different possible service lifetime patterns.
DATALEAK: Data Leakage Detection System
Authors: Skrop Adrienn
Published: May 2015

Data leakage is an uncontrolled or unauthorized transmission of classified information to the outside. It poses a serious problem to companies as the cost of incidents continues to increase. Many software solutions were developed to provide data protection. However, data leakage detection systems cannot provide absolute protection. Thus, it is essential to discover data leakage as soon as possible. The purpose of this research is to design and implement a data leakage detection system based on special information retrieval models and methods. In this paper a semantic informationretrieval based approach and the implemented DATALEAK application is presented.

Authors: Máté Márton , Hollanda Dénes , Egyedfaluvégi Erzsébet
Published: May 2015

Some cutting tools work in kinematic conditions that differ consistently from the hypothetical conditions admitted in the phase of project. Especially in case of gear cutting the difference between the main cutting velocity vector and total cutting velocity vector can't be neglected. The present paper analyses the constructive and the functional geometry of the milling head's arbitrary cutting edge and emphasizes the dependence of the real cutting geometry of the constructive elements and the kinematic peculiarities of the cutting process, where the relative position of cutting tool and cut gear becomes a severe factor of influence.
Designing Fatigue Experiment for Investigating Polymer Specimens
Authors: Fodor Antal , Boza Pál
Published: May 2015

The using of „technical materials” speeded up lately. Because of this, parts are being designed from plastic, which have to sustain extreme stresses. The proper definition of material qualities is expensive; despite in every phase of designing, we need it to be done perfectly. In every industrial section it is important to work with exact material qualities, especially areas where there are strict safety rules (in connection with the lifespan). In this work we will introduce how to design suitable fatigue stress for the plastic samples and how to define the fatigue qualities of the various materials of Rapid Prototyping. This information could be important to change damaged equipments and parts in the military. Due to this, we performed the design of fatigue tests to help the designers elaborate military, safety improvements and proper renewing technologies.
Innovation in retinal diseases – ultra-widefield imaging
Authors: Dolar-Szczasny Joanna , Święch-Zubilewicz Anna , Mackiewicz Jerzy
Published: May 2015

The understanding of retinal disease has evolved rapidly with a growing number of clinical evidence supplied by ultrawidefield retinal imaging.

Optos 200Tx ultra-widefield retinal imaging system uses a scanning laser ophthalmoscope, as well as an ellipsoid mirror. This creates a possibility of making a virtual focal point inside the eye and, in turn, enables the system to simultaneously make a single capture of the central retina and periphery. This system offers multimodal ultra-widefield imaging, including color photographs, fundus autofluorescence images, red-free images and fluorescein angiography (FA), allowing visualization of the retinal circulation. For color photographs, green and red lasers are used simultaneously to allow visualization of retinal substructures from the sensory retina and retinal pigment epithelium to the choroid.

In our clinic ultra-widefield fluorescein angiography has became an elegant diagnostic imaging modality that has improved our ability to diagnose and plan treatment strategies.

In the future widefield imaging will probably be coupled with OCT (optical coherence tomography) option to better evaluate retinal pathologies in the periphery.
What’s new about symptomatic reflux disease
Authors: Solecki Michał , Wallner Grzegorz , Masiak Wioletta , Ćwik Grzegorz
Published: May 2015

During the last 4 decades reflux disease (GERD) has evolved from being a rare clinical problem to a disease with high incidence. This automatically rises its social costs. First descriptions came from western countries only but nowadays there are many published papers from Asia and Middle East that can be found on the Internet. There is no clear explanation for this fact. Our understanding of GERD has changed over the time. At first GERD, hiatal hernia and oesophagitis were synonyms. Since the 1940s when the first manometrical studies were done it was concerned as lower oesophageal sphincter or peristaltic disfunction. The following years gave a definition of acid-peptic disorder. Nowadays all this concepts are mixed together and we are considering GERD as a heterogeneous clinical problem. In this paper we would like to present up-to-date knowledge about GERD.

Published: May 2015

Effective treatment of peritoneal surface neoplasms is possible through the simultaneous use of cytoreductive surgery with intraperitoneal chemotherapy in hyperthermia. It is successfully performed in patients with peritoneal pseudomyxoma, mesothelioma, as well as a limited and resectable peritoneal carcinomatosis in the course of colorectal cancer. It can also be used in patients with gastric or ovarian cancer but also metastatic colorectal cancer or metastases to the ovaries from gastric cancer. Aggressive surgical management of patients with primary or secondary neoplasms of the peritoneal surface was initiated by Sugarbaker’s research group.

Published: May 2015

The number of patients with type 2 diabetes increases along with civilizational development. Advanced treatment methods applied in diabetology and other branches of medicine increase the number of patients. The aim of this work is to present diagnostic and therapeutic problems in elderly people with diabetes. There isa a number of other diseases coexisting with diabetes. These are: hypertension, hyperlipidemia and obesity. The risk of diabetes increases with age and it is related to lowered insulin secretion, worsened absorption and insulin resistance. Diabetes symptoms in older patients differ from those of other age groups. An early diagnosis can minimize the risk of any cardiovascular events, ranked as one of the leading causes of death in elderly patients. The choice of treatment should be adjusted to the particular patient’s needs, avoid any sudden modifications of administered drugs and educating the patients. These are the most important elements of the therapy.

Motor organ injuries are one of the most common consequences of trauma, out of which comminuted fractures with a bone loss are the most challenging. Numerous methods are applied to treat these injuries; however, still in many cases we are unable to suggest successful medical treatment. Therefore, treating these injuries using elastic and surgically handleable bone replacement materials was started at Trauma Surgery and Emergency Medicine of Medical University of Lublin (provided for the experiments by Medical Inventi Lt). Preliminary assessment based on the results of treatment with bone replacement materials of two patients with comminuted fractures of femur was promising. Bone union was achieved without any adverse effects.

Authors: Heidler Maria-Dorothea , Salzwedel Annett , Liero Hannelore , Jöbges Michael , Völler Heinz
Published: May 2015

Introduction: Variables predicting successful decannulation from a tracheotomy tube after long-term mechanical ventilation remain obscure.

Material and methods: To identify such predictors, data from 150 consecutive critically ill patients with a tracheotomy for the purpose of mechanical ventilation were analyzed retrospectively. Of the 150 tracheotomized patients who were admitted to a rehabilitation center, 103 were successfully decannulated. Items concerning socio-demographic data, indication for mechanical ventilation (neurologic, cardiologic, respiratory or gastro-intestinal disease), comorbidities, tracheotomy technique (dilatational vs. surgical), duration of mechanical ventilation, complications during weaning from tracheotomy tube, and also care dependency, alertness and the degree of aspiration at admission to the rehabilitation clinic were tested using a multiple logistic regression model.

Results: A successful decannulation was associated with no complications during decannulation procedure (OR 0.175, 95% CI; p=0.002), high alertness at the beginning of rehabilitation (OR 1.079, 95% CI; p=0.014), female gender (OR 0.338, 95% CI; p=0.031), a low number of comorbidities (OR 0.737, 95% CI; p=0.043), and dilatational tracheotomy (OR 2.375, 95% CI; p=0.054).

Conclusions: The identified predictor variables can be collected easily in the clinical routine. Except for complications during decannulation procedure all predictors can be assessed at admission with the result that a prediction of decannulation success is possible very early in clinical course.
Efficiency of inclusive physical education lessons for schoolchildren with minor deviations in health
Authors: Ivanna Bodnar , Eugene Prystupa
Published: May 2015

Introduction: Some contradictory data regarding the effects of inclusive physical education were revealed. The purpose of the research is to determine the efficiency of inclusive physical education for schoolchildren of I-III health groups of middle school age on the base of indices of complaints connected with health conditions, mental development, and physical activity.

Material and methods: theoretical knowledge, sociological, educational, psycho diagnostics (degree of anxiety by Spielberger - Hanin, HAM: health, activity, mood) auto timing of motor activity (the Framingham method). The experimental group consisted of schoolchildren who were studying at secondary schools in inclusive terms - in these schools physical culture lessons for schoolchildren of I-III health groups were held both for practically healthy children and children with minor deviations in health status (with differentiation of tasks depending on the needs and capabilities of each child). The control group consisted of schoolchildren from the schools where the physical education lessons were conducted separately (segregatively) for schoolchildren of base, preparatory, and special medical groups. The study involved 1414 pupils of secondary school age (5-9 grades). The experimental group consisted of 694 individuals (320 girls and 374 boys) - the control one - 720 individuals (332 girls and 388 boys).

Results: The trend toward the decreasing of the number of schoolchildren complaining of health condition with years of training in the experimental group confirmed the higher efficiency of inclusive physical education. Inclusive physical training lessons are less psychologically traumatic than segregative ones because schoolchildren from different medical groups in such terms suffer from the high level of anxiety less; low, often subjective, self-estimation, well-being, activity and mood are significantly higher. Positive changes in mental health are observed in the most tangible inclusive environment among schoolchildren with health deviations. Intensive everyday household physical activity and sports confirm the benefits of inclusive physical education.

Conclusions: A high efficiency inclusive physical education student of I-III health groups was proved.

Celem pracy jest przedstawienie wynikow leczenia zachowawczego 12-letniej dziewczynki z progresywną skoliozą idiopatyczną.

Opis przypadku: Diagnostykę fizjoterapeutyczną przeprowadzono po raz pierwszy w marcu 2010 roku z powodu zaobserwowanej przez matkę asymetrii ustawienia łopatek. Pacjentkę skierowano do poradni ortopedycznej w celu dalszej diagnostyki. W badaniu radiologicznym stwierdzono: prawostronne wygięcie kręgosłupa w odcinku piersiowym (Th6-Th11, 30°) oraz lewostronne w odcinku piersiowo-lędźwiowym (Th11-L4, 30°), test Rissera (0). Zalecono leczenie gorsetem Cheneau (23 godz./dobę) oraz intensywną fizjoterapię. Na podstawie wywiadu z rodzicami dziewczynki ustalono, że zalecenia dotyczące noszenia gorsetu i ćwiczeń nie były w domu przestrzegane. Kontrolne zdjęcie rentgenowskie wykonane we wrześniu 2010 roku wykazało progresję prawostronnego skrzywienia w odcinku piersiowym (Th6-Th11, 36°). Zalecono zwiększenie systematyczności noszenia gorsetu i wykonywania ćwiczeń. Zdjęcie rentgenowskie wykonane w czerwcu 2011 roku wykazało zmniejszenie wartości kątowych skrzywienia: Th6-Th11, 18° oraz Th11-L4, 14°. Test Rissera określono na (1). Wystąpienie pierwszej miesiączki odnotowano w listopadzie 2011 roku. Pacjentka kontynuowała leczenie gorsetem i fizjoterapią. We wrześniu 2013 roku wykonano kontrolne zdjęcie rentgenowskie (Th5-Th11, 15°, Th11-L4, 11°). Test Rissera określono na (4). Zalecono zakończenie leczenia gorsetem oraz kontynuację fizjoterapii w celu poprawy estetyki sylwetki.

Podsumowanie i wnioski: Leczenie zachowawcze (gorset i fizjoterapia) może prowadzić do zmniejszenia wielkości kątowej skrzywienia u dzieci z progresywną SI.

Streszczenie

W prezentowanym opracowaniu podjęto analizę poglądow i postaw wobec niepełnosprawności na przestrzeni dziejow cywilizacji zachodniej. Wskazano także na pewne uproszczenia, a nierzadko przekłamania, ktore pojawiały się w opisie analizowanej rzeczywistości, głownie pod wpływem pewnych ideologii. W części drugiej opracowania poddano analizie ewolucję pedagogiki specjalnej, ukazując uwarunkowania tegoż rozwoju, a także zmieniającą się - w związku z tym - sytuację człowieka słabego. W części tej przedstawiono także zagrożenia zdrowia i rozwoju człowieka, jakie niesie wspołczesna kultura, zwłaszcza dla człowieka słabego. W końcowej, trzeciej części opracowania przedstawiono propozycje działań edukacyjnych, ktore w konsekwencji mogą doprowadzić do właściwych (dobrych) zmian społecznych, poprawiających trudną sytuację i relacje osob słabych.
Dotyk w relacji fizjoterapeuta – pacjent a granice kontaktu fizycznego / Touch in the physiotherapist patient relationship – limits of physical contact
Authors: Dadura Emilia , Wójcik Agnieszka
Published: May 2015

Streszczenie

Wstęp: Relacja fizjoterapeuta - pacjent jest specyficznym rodzajem kontaktu, ponieważ w jej ramach dochodzi do naruszania granic definiowanych przez normy społeczno - kulturowe, chociażby poprzez osobiste pytania czy też fizyczny kontakt, wymagany w trakcie niektórych procedur diagnostyczno - leczniczych. Relacja terapeutyczna generuje pewien rodzaj bliskości, gdyż w trakcie leczenia dochodzi do kontaktu pomiędzy fizjoterapeutą a pacjentem na płaszczyźnie fizycznej, psychicznej i społecznej. Tego typu sytuacja może sprzyjać próbom naruszania granic przez każdą ze stron interakcji.

Celem badań pilotażowych było ukazanie z perspektywy fizjoterapeuty problemu granic w relacji terapeutycznej oraz nakreślenie obszarów, które w przyszłości należałoby zbadać w ramach tego zagadnienia.

Materiał i metody: Badaniem objęto grupę 80 losowo wybranych fizjoterapeutów (39K/41M) z czterech placówek. Posłużono się autorską ankietą, wypełnianą anonimowo (28 pytań - zamknięte, otwarte i półotwarte).

Wyniki: 56% badanych nie doświadczało naruszania granic ze strony pacjentów, 37% zetknęło się z tym problemem, podając najczęściej dotyk z podtekstem seksualnym, usiłowanie pocałunku i agresję. Znaczna większość respondentów (65%) uznała, że normy ograniczające kontakty seksualne z pacjentami są słuszne i należy ich przestrzegać, z czego 26% dopuszczało odstępstwa od wspomnianych norm. Dla 86% badanych płeć pacjenta nie miała znaczenia, 14% respondentów preferowało pracę z kobietami.

Wnioski: Większość fizjoterapeutów w trakcie wykonywania czynności zawodowych nie doświadcza ze strony pacjentów naruszania dopuszczalnych granic kontaktu fizycznego. Badani, mimo iż w większości akceptują zasadność istnienia granic etycznych dotyczących kontaktów intymnych z pacjentami, dopuszczają od nich pewne odstępstwa. Płeć leczonego pacjenta i związana z nią sfera seksualna zdaje się nie stanowić dla fizjoterapeutów znaczącej bariery w trakcie pracy manualnej.

Streszczenie

Wstęp: Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) jest międzynarodową organizacją wyznaczającą standardy leczenia osób ze skoliozami i prowadzenia badań naukowych w tej dziedzinie. Standardy leczenia uwzględniają konieczność stosowania fizjoterapii. Wytyczne SOSORT określają jakie warunki powinny spełniać metody fizjoterapii stosowane w procesie leczenia. Jedną z koncepcji stosowanych na świecie w procesie leczenia zachowawczego osób ze skoliozą jest metoda Proprioceptive Neuromuscular Facilitation (PNF). International PNF Association (IPNFA) tworzy standardy nauczania, stosowania metody PNF i prowadzenia badań naukowych związanych z koncepcją.

Cel: Celem pracy jest proba wykazania zgodności założeń metody PNF z wytycznymi SOSORT dotyczącymi leczenia zachowawczego skolioz.

Materiał i metody: Do analizy wykorzystano rekomendacje SOSORT stworzone w latach 2005 - 2012 oraz informacje i wiedzę zgodną z aktualnymi ustaleniami International PNF Association (IPNFA).

Wyniki: W pracy wykazano zgodność założeń metody PNF z wytycznymi SOSORT odnoszącymi się do fizjoterapii takimi jak: indywidualne planowanie leczenia, ukierunkowanie na główne cele leczenia (zatrzymanie progresji skrzywienia, poprawa funkcji układu oddechowego, zmniejszenie dolegliwości bólowych, względy estetyczne) oraz możliwość specjalistycznego oddziaływania na deformacje kręgosłupa (autokorekcja kręgosłupa i miednicy w trzech płaszczyznach, stabilizacja postawy, trening czynności codziennych, edukacja zdrowotna). Wstępne badania wykazują pozytywny wpływ wybranych wzorców metody PNF na parametry posturalne osób ze skoliozą.

Wnioski: Szczegółowo opisana struktura metody PNF może być wykorzystana przy planowaniu badań naukowych. Konieczne jest prowadzenie badań mających na celu wykazanie skuteczności metody PNF w procesie leczenia osób ze skoliozą.

Streszczenie

Wstęp: Zespoły bólowe odcinka lędźwiowego kręgosłupa są powszechnym problemem współczesnych społeczeństw. Rzetelna diagnoza funkcjonalna jest kluczem do postawienia rozpoznania oraz stanowi pierwszy etap do rozpoczęcia leczenia tego schorzenia oraz zapobiegania jego nawrotom. Celem pracy było zbadanie zgodności stawianej diagnozy przez początkującego terapeutę po ukończeniu kursu „A” według metody McKenziego w porównaniu z diagnozą stawianą przez instruktora metody z wieloletnim doświadczeniem.

Materiał i metody: Badania były prowadzone w Instytucie McKenziego Polska w Poznaniu. Pacjentami (n=30) z bólami odcinka lędźwiowego kręgosłupa poddani zostali diagnostyce metodą McKenziego. Analizie poddano następujące elementy diagnozy i leczenia: rozpoznanie, kierunkową preferencję ruchu, wybór pozycji wyjściowej do ćwiczeń oraz ich częstotliwość.

Wyniki: Na podstawie przeprowadzonych badań stwierdzono zgodność diagnoz na poziomie: 75%, 100%, 100% i 78% odpowiednio dla zmiennych: rozpoznanie, kierunek leczniczy, pozycja wyjściowa i częstotliwość ćwiczeń.

Wnioski: 1. Kurs „A” metody McKenziego, jako pierwszy etap szkolenia pozwala w pełni przygotować terapeutę do zadań takich jak diagnostyka i planowanie terapii pacjentow z dolegliwościami bólowymi kręgosłupa lędźwiowego.

2. Metoda McKenziego umożliwiła minimalizację błędów diagnostycznych, pomimo dużej różnicy w doświadczeniu diagnostów.

3. Różnice wynikające z doświadczenia diagnostów istniały przede wszystkim w sytuacjach diagnozowania pacjentów kwalifikujących się do grupy „inne”.
The diagnosis of a cervical tumefaction in children
Authors: Sarafoleanu Dorin , Enache Raluca
Published: May 2015

Neck pathology in children involves many diseases with similar clinical expression. Different disorders in paediatric practice may be clinically manifested by a cervical tumefaction. The cervical tumefaction can be represented by adenopathies or tumors. Cervical adenopathies may be unilateral or bilateral; the cause of their occurrence may be infectious, inflammatory, tumoral or may be associated with rare diseases. Tumoral cervical tumefactions can be represented by: congenital cervical cysts and fistulae, cystic lymphangiomas, thyroid swellings, malformations and cervical tumors detected antenatally. A correct diagnosis is established after a complete clinical and paraclinical assessment. In this article the authors make a review of the types of cervical tumefactions in children, emphasising the diagnostic protocol.

Authors: Budu Vlad , Schnaider Alexandra , Tache Maria Sabina , Bulescu Ioan
Published: May 2015

BACKGROUND. The ostiomeatal complex (OMC) is the anatomical region situated between the middle turbinate and the lateral nasal wall, at the level of the middle meatus. Common anatomical variations of OMC are concha bullosa, hypertrophy of the uncinate process and of the bulla ethmoidalis and Haller’s cell. Our study was aimed to investigate the prevalence of these conditions and their relations to different symptoms.

MATERIAL AND METHODS. The study is a retrospective descriptive study based on 256 files of patients who were hospitalized and treated for OMC pathology in our clinic between January 2009 and January 2014. The data acquired were included into Excel Worksheets and statistically analyzed using GraphPad Software.

RESULTS. The most common finding was concha bullosa (63.67%), followed by hypertrophy of the bulla ethmoidalis (10.93%) and of the uncinate process (10.15%). Haller’s cell was found in only 3% of cases. The most common symptom for all patients was nasal obstruction, followed by nasal discharge. The majority of symptoms improved after functional endoscopic sinus surgery for OMC drainage.

CONCLUSION. OMC pathology is a frequent indication for functional endoscopic sinus surgery. The most common condition that determines blockage of OMC and need for surgical treatment is concha bullosa. The most common complaint of patients with OMC pathology is nasal obstruction.

Authors: Chistruga-Blajin Viorica , Alexandru Sandul
Published: May 2015

BACKGROUND. Chronic maxillary sinusitis is a frequently encountered pathology, resistant to treatment, which can cause significant economic losses. Considering these aspects, it is necessary to develop new methods of treatment.

OBJECTIVE. The purpose of this study was to assess the therapeutic efficacy of the “Cahul” ozonated mineral water in the treatment of experimentally induced chronic rhinosinusitis and its action on the mucosa of the maxillary sinus.

MATERIAL AND METHODS. The experimental study was conducted on a group of 14 chinchilla rabbits, aged between 8 and 12 months, weighing 2.5-3.0 kg, kept in vivarium conditions. In the first stage of the study, chronic rhinosinusitis was induced. 3 months after, maxillary antrostomy in the medial wall was performed on all animals included in the study; the intervention was performed under general anesthesia. The rabbits were divided into two groups. The rabbits enrolled in the study group underwent daily inhalations and maxillary sinus lavage with the “Cahul” ozonated mineral water. In the control group, inhalations and lavage were performed with 0.9% NaCl solution. Efficacy of the treatment was assessed observing the clinical character of the pathology. On days 2, 5 and 9 of the experiment, endoscopic and histological examinations were performed.

RESULTS. On the ninth day of treatment, if in the study group the appearance of the sinus mucosa was almost normal, in the control group, the histological examination revealed: epithelial hyperplasia, cylindrical cell hyperplasia, thickening of the basement membrane and lymphocyte infiltration. Mucosal fragments harvested after 5 days revealed submucosal fibrosis, leukocyte infiltration in the control group being more pronounced than in the study group.

CONCLUSION. Maxillary sinus lavage with the “Cahul” ozonated mineral water improves mucociliary clearance and stimulates regeneration of affected cells.
