    Opis:
    Threats associated with the production, storage and use of warfare agents containing high explosives against the backdrop of political and social events emerging in the 21st century present new challenges for specialized laboratories involved in detecting contamination and identifying its source. A common analytical problem in studies conducted in the ecosystem is the low concentration of the test substance - below the detection limit of the instrument. Helpful in solving this dilemma are accumulation bio-markers, which appear to be an excellent tool for detecting contamination in, for example, flowing water. Such biomarkers make it possible to determine the presence of specific chemical agents at the same time they are a sensitive indicator of the ecosystem's response to contamination. The presented chromatographic method allows quantitative and qualitative determination of 2,6-diamino-4-nitrotoluene, 2,4-diamino-6- nitrotoluene, 1,3,5-trinitrobenzene, trinitrotoluene, 2-amino-4,6-dinitrotoluene, 4-amino-2,6- dinitrotoluene and tetryl in the biological matrix. The effects of accumulation in the tissue of crustaceans on TNT test solutions were studied from 1 to 24 hours. The saturation effect was observed and the concentration of TNT derivatives was measured. The observed effects confirmed the usefulness of the selected larva as a bio-indicator of TNT contaminant accumulation in the ecosystem.
    agrożenia związane z produkcją, przechowywaniem oraz użyciem środków bojowych zawierających kruszące materiały wybuchowe na tle wydarzeń politycznych i społecznych pojawiających się w XXI wieku stanowią nowe wyzwania dla specjalizowanych laboratoriów zajmujących się wykrywaniem skażeń oraz identyfikowaniem źródła jego pochodzenia. Częstym problemem analitycznym w badaniach prowadzonych w ekosystemie jest niskie stężenie badanej substancji – poniżej limitu detekcji urządzenia. Pomocne w rozwiązaniu tego dylematu są biowskaźnik kumulacji, które wydają się doskonałym narzędziem do wykrywania zanieczyszczeń np. wody płynącej. Biomarkery takie umożliwiają stwierdzenie obecności określonych czynników chemicznych jednocześnie są czułym wskaźnikiem reakcji ekosystemu na skażenie. Przedstawiona metoda chromatograficzna pozwala ilościowo i jakościowo oznaczyć 2,6-diamino-4-nitrotoluen, 2,4-diamino-6-nitrotoluen, 1,3,5-trinitrobenzen, trinitrotoluen, 2-amino-4,6-dinitrotoluen, 4-amino-2,6-dinitrotoluen oraz tetryl w matrycy biologicznej. Badano efekty kumulacji w tkance chruścików na roztworach testowych trotylu w czasie od 1 do 24h. Zaobserwowano efekt wysycenia oraz zmierzono stężenie pochodnych trotylu. Zaobserwowane efekty potwierdziły użyteczność wytypowanej larwy jako biowskaźnika akumulacji zanieczyszczeń trotylu w ekosystemie. Zaobserwowane efekty potwierdziły użyteczność wytypowanej larwy jako biowskaźnika akumulacji zanieczyszczeń trotylu w ekosystemie.

    Opis:
    The purpose of this study was to evaluate pain reduction as the main parameter for monitoring improvements in Health-Related Quality of Life (HRQoL) in a female patient following endovascular treatment of Pelvic Congestion Syndrome (PCS). A 38-year-old female patient with chronic intermittent, “dragging” abdominal pain, lasting more than two years, mainly in the lower abdomen, radiating to the sacral region, underwent SARS CoV-2 infection in October 2021, and COVID-19, which lasted 10 days. Eight months later, complaints of pain in the lower abdominal area, during the menstrual cycle, during prolonged standing, after sports activities and during and after intercourse, increased. The patient was compelled to begin diagnosis of these complaints due to the severe pain and concerns about whether she had contracted cancer of the cervix uteri. She was diagnosed on transvaginal ultrasound-Doppler and Angio-MR of the pelvic vessels with PCS. Treatment was undertaken at the Department of Vascular Surgery and Endovascular Interventions, St. John Paul II Hospital, Krakow, Poland. Intraoperatively, after confirmation through selective angiography, of previously diagnosed insufficiency of the left ovarian vein (LOV) and of the parametrial veins (PMV), the selective obliteration was performed with an adhesive dedicated to endovascular closure of veins and vascular malformations (Glubran®2). The range of pain intensity, according to theVisual Analogue Scale (VAS), in Exam. 1 (before surgery), was in the premenstrual period (BM) 7.0 points, which increased during menstruation (DM) or after intense activity (AIA) to 8.0 points, and occasionally during and after intercourse even to 9.0 points. These values were very high, indicating that pain significantly affected the patient's quality of life. The extent of pain severity decreased significantly in Study 2 (two months after surgery) and Study 3 (four months after surgery) and was 2.0 points in the premenstrual period (BM), which increased only slightly during menstruation (DM) or after intense activity (AIA) to 3.0 points, and decreased again to 2.0 points during and after intercourse. The patient reported that the procedure significantly and positively affected her functioning in daily life, especially in caring for a young child, which is evidence of the achievement of HRQoL improvement. Endovascular treatment for Pelvic Congestion Syndrome (PCS) was effective in reducing pain and improving the Health-Related Quality of Life (HRQoL) of a patient with PCS.

    Opis:
    Introduction. Cerebral palsy (CP) is a problem presenting multiple issues and the prevalence of this condition is quite significant. CP risk factors are mainly observed in prematurely born children as well as those affected by complications around the time of birth or during the period of mother’s pregnancy. Quite frequently CP is manifested by abnormal muscle tone, contractures and deformities, and consequently impaired fine and gross motor functions. Aim. The study was designed to examine the level of hand function, i.e. fine motor skills and to investigate whether there is a correlation between development of fine motor and gross motor functions. Material and methods. The study group included 80 children with infantile CP. In the group there were 24 cases with spastic diplegia, 36 with spastic hemiplegia, and 20 with bilateral hemiplegia. During the study the children performed Box and Blocks test, and their parents filled in Manual Ability Classification System (MACS) describing the level of fine motor function development in their children. The children were additionally asked to perform two motor tasks. The first one involved an attempt to assume position on all fours, and the other one checked the ability to assume and maintain standing position. Results. The best scores in the conducted tests were found in children with CP taking the form of spastic diplegia, and the poorest scores in MACS, Box and Blocks test as well as in motor tasks assessing gross motor function were observed in children with bilateral hemiplegia. Conclusion. The form of infantile CP affects the level of manual abilities. There is a correlation between the level of gross motor and fine motor functions development.

    Opis:
    The aim of the study was to determine the level of functional independence in adult patients with previously undiagnosed or untreated phenylketonuria (PKU). The study was conducted among 400 intellectually impaired adult residents of Social Welfare Homes in South-Eastern Poland born prior to the introduction of neonatal PKU screening programs. PKU was screened by filter paper test using tandem mass spectrometry methods, and confirmed by gas chromatography-mass spectrometric analysis of PKU organic acids in urine. Degree of functional independence included the assessment of activities of daily living (Barthel Index) and measures of balance and gait (Tinetti scale). Eleven individuals with previously untreated PKU were identified whereby eight presented with moderate disability and three with mild disability. Six had a high risk of falls and five had a moderate risk of falls. This study indicates that there is considerable number of undiagnosed PKU patients within the Polish population who require assessment and management in order to reduce the impact of the neurological and neuropsychiatric problems associated with the condition. Appropriate therapy for those with undiagnosed PKU should, in particular, address the risk of falls.

    Opis:
    Delusional misidentification syndrome (DMS) is an umbrella term for syndromes of intermetamorphosis, Fregoli, and Capgras. DMS) is thought to be related to dissociation between recognition and identification processes. DMS was described for the first time in 1932 as a variant of the Capgras syndrome and is currently on the DSM-V list of diseases as an independent disease entity. Patients affected by DMS believed that people around them, most often family, have changed physically (appearance) and mentally (character). Other symptoms include confabulation, derealization or depersonalization. In patients, aggressive behavior is often observed, aimed at alleged doppelgangers resulting from the sense of being cheated and manipulated. With the intermetamorphosis syndrome, for example, schizophrenia, depression, bipolar disorder or other misidentification syndromes (Fregoli's, Capgras) may coexist. There is also a reverse intermetamorphosis, where the object of the changed appearance or character becomes the patient himself. One of its forms may be lycanthropy. The etiology of the intermetamorphosis has not been fully understood, one of the reasons may be brain damage and changes in the parietal and/or temporal lobes of the right hemisphere. It may then damage long neuronal connections to the frontal areas of the brain, disturbances of working memory (WM) accountable for the keep and online management of data, so that it is available for further processing, and the patient's will be uncritical. The basic method of diagnosis of this delusion is a medical interview with the patient. Other diagnostic methods include computed tomography, magnetic resonance imaging, EEG and ERPs. Experimental methods include searching for the neuromarker of DMS. Currently, there are no treatment guidelines of this delusional disorder, and pharmacotherapy experimental, but the drugs from the group of neuroleptics and lithium seem effective. Some hope for the treatment is created by neurotherapy, but it is also experimental.

    Introduction Since 1 January 2016 certain groups of nurses and midwives (N&Ms) have been entitled to administer certain medicines to patients and issue perceptions for it (independent nurse prescribing - INP), issue prescriptions upon physician's order (supplementary nurse prescribing - SNP) and to refer patients to determined diagnostic tests. Students’ knowledge on the possibility and principles of nurse prescribing seems to be important. Aim of study To evaluate the knowledge of 1st year students of Bachelor’s studies in nursing and midwifery on the possibility and principles of prescribing authorities of N&Ms in Poland. Material and methods 2338 1st year students of Bachelor’s nursing (1941) and midwifery (398) studies from 26 state higher vocational schools of universities. Own questionnaire assessed in the pilot study; the internal reliability of measurement on the knowledge rating scale was estimated by calculating Cronbach’s alpha reliability coefficient Results Group of 11% to 64% (depending on a question) gave correct answers. 14 % knew criteria which N&Ms are required to meet in order to refer patients to diagnostic tests. Almost 2/3 of the interviewees also knew where to find the list of active substances allowed in medicines independently prescribed by N&Ms. The internal reliability of the knowledge rating scale was 0,389. Conclusions The knowledge of students regarding N&Ms’ prescribing powers is superficial, but most of respondents knew the crucial issues. It is necessary to correctly determine education standards and to focus on their implementation tools, so that those concerned could acquire desired competences during studies.

    Opis:
    The article describes three interlaboratory experiments concerning 222Rn determination in water samples. The first two experiments were carried out with the use of artificial radon waters prepared by the Laboratory of Radiometric Expertise (LER), Institute of Nuclear Physics, Polish Academy of Sciences in Kraków in 2014 and 2018. The third experiment was performed using natural environment waters collected in the vicinity of the former uranium mine in Kowary in 2016. Most of the institutions performing radon in water measurements in Poland were gathered in the Polish Radon Centre Network, and they participated in the experiments. The goal of these exercises was to evaluate different measurement techniques used routinely in Polish laboratories and the laboratories’ proficiency of radon in water measurements. In the experiment performed in 2018, the reference values of 222Rn concentration in water were calculated based on the method developed at LER. The participants’ results appeared to be worse for low radon concentration than for high radon concentrations. The conclusions drawn on that base indicated the weaknesses of the used methods and probably the sampling. The interlaboratory experiments, in term, can help to improve the participants’ skills and reliability of their results.
