Hidatidosis of the Spleen

100%
EN
Hydatidosis of the spleen (SH) is an extremally rare condition. The aim of the study was to present our experience and discuss diagnostic methods and therapeutical options in cases of spleen hydatidosis. Material and methods. Between 1993 and 2008, 8 patients were diagnosed with SH, 6 of whom were operated on (4 males and 2 females). Their average age was 44.5 years (the age range 30-59 years). Four patients presented isolated SH, one had a spleen and liver hydatidosis and there was also a case of one spleen, liver and peritoneal hydatidosis. Results. The main symptom of the condition was abdominal pain and hydatidosis serology was always positive. The average hydatidisis cyst size was 13.3 cm (range: 7-18 cm). Splenectomy was performed in 5 cases and a partial cystectomy in one case. A left lateral sectionectomy was required in 1 case, a segment III subsegmentectomy was delivered in 1 case and multiple cystectomies in the case of the patient with disseminated hydatisis. In the follow-up period of the above mentioned surgical procedures no mortality among the treated patients was reported. The majority of patients did not present any symptoms of morbidity (4 patients). We registered one wound infection and one cavity abscess solved with percutaneous drainage in the patient following partial cystectomy. The hospitalisation period avaraged to 5 days (within the range of 5 to 12 days). The patients’ follow-up was 98 months on average (range:19-190 months) without any traced relapse. Conclusions. Total splenectomy is the treatment of choice of SH. Other surgical techniques could be employed in special cases

Purpose. The purpose of this study was to analyze scientific evidence on the effects that Nordic Walking (NW) has on the human body. Basic procedures. A comprehensive search of computer databases (MEDLINE/PubMed, CINAHL, and SPORTDiscus) was conducted to identify relevant English and Polish studies on NW that were published from 1995 to 2009 and based on scientific research. Main findings. A total of 26 studies met the inclusion criteria. The majority of studies (12) discussed physiological issues, eleven studies were dedicated to NW as a form of rehabilitation (including one case study), and three studies focused on biomechanical issues present in NW. Conclusions. Not all of the widely promoted benefits of NW were confirmed in the results of the found scientific studies. Often analyzed issues did not provide sufficient explanation. There is a large discrepancy in the results of physiological responses during NW in a variety of conditions (on a treadmill with/without grade; field - uphill/downhill/horizontal level terrain). The results of studies analyzing the effects of NW training as a form of rehabilitation particularly in the areas of cardiology confirmed the positive aspects of including NW towards a patient's rehabilitation after acute coronary syndrome, with intermittent claudication, and after coronary artery disease, or after myocardial infarction. Contrary to popular belief and previously done studies, recent research has shown that NW does not reduce the loading of the knee joint.

Technology of molecularly imprinted polymers (MIP) has become very popular in recent decades. MIPs are primarily used in medical diagnostics, chromatographic separation and solid phase extraction (SPE); also as sensors and catalysts. In recent years there have been reported benefits of combining molecular imprinted polymers with additional features, e.g. magnetic properties, through the build-up of this type of material on magnetite particles (Magnetic Molecularly Imprinted Polymer – MMIP). This method produces a multifunctional material which has high selectivity and the ability to isolate the analyte from biological and environmental samples, allowing effective purification from such interferents as proteins and fats. This developing branch of new materials for the preparation and purification of complex sample matrices is an interesting alternative to materials routinely used to date, particularly with regard to the immunosorbents. This paper summarizes recent reports regarding MMIP preparation and their application for purification and isolation of compounds from biological matrices.

This review classifies and analyzes over fifty heterohepta- and heterooctanuclear platinum clusters. There are eight types of metal combinations in heteroheptanuclear: Pt6M, Pt5M2, Pt4M3, Pt3M4, Pt2M5, PtM6, Pt3Hg2Ru2 and Pt2Os3Fe2. The seven metal atoms are in a wide variety of arrangements, with the most common being one in which the central M atom (mostly M(I)) is sandwiched by two M3 triangles. Another arrangement often found is an octahedron of M6 atoms asymmetrically capped by an M atom. The shortest Pt-M bond distances (non-transition and transition) are 2.326(1) Å (M = Ga) and 2.537(6) Å (M = Fe). The shortest Pt-Pt bond distance is 2.576(2) Å. In heterooctanuclear platinum clusters there are eight types of metal combinations: Pt6M2, Pt4M4, Pt3Ru5, Pt2M6, PtM7, Pt2W4Ni2, PtAu6Hg and PtAu5Hg2. From a structural point of view, the clusters are complex with bicapped octahedrons of eight metal atoms prevailing. The shortest Pt-M bond distances (non-transition and transition) are 2.651(3) Å (M = Hg) and 2.624(1) Å (M = Os). The shortest Pt-Pt bond distance is 2.622(1) Å. These values are somewhat longer than those in the heteroheptanuclear clusters. Several relationships between the structural parameters were found, and are discussed and compared with the smaller heterometallic platinum clusters

PDGF is one of the most potent serum mitogens, and the signalling mechanism by way of its receptor tyrosine-kinase has been extensively studied since its first purification in 1979. The identification of homology between the simian sarcoma virus oncogene, v-sis, and the B-chain of PDGF, as well as the frequent over-expression of both the ligands and receptors in various tumours and stroma led to the proposal of the PDGF-mediated autocrine and paracrine hypothesis. Consistent with the important roles of PDGF in the growth and survival of cells, the expression and activity of PDGF receptors are tightly controlled by both positive and negative feedback mechanisms at different levels. The deregulation of the control system can result in serious pathological conditions such as chronic inflammation and tumours. Understanding the molecular mechanisms for the regulatory system and the signalling pathway of PDGF is essential in order to find effective therapies in the diseases where PDGF is involved.

Granulocyte colony-stimulating factors, introduced in the 1990s to prevent neutropenic fever, improve patients’ prognosis after myelotoxic chemotherapy. G-CSFs accelerate bone marrow recovery, shortening the duration of neutropenia and reducing its intensity as well as the risk of febrile neutropenia. There are short- and long-acting G-CSFs available these days. This paper is a review of the efficacy, toxicity and indications for short- and long-acting G-CSFs as indicated in the most recent studies.

Recenzowana książka wpisuje się w listę lektur ukazujących problemy szkolnego wychowania fizycznego i poszukujących skutecznego ich rozwiązywania.Przygotowanie takiego opracowania polega, jak pisał Maciej Demel (1973, s. 7), „na krytycznym atakowaniu współczesności, przezwyciężaniu tradycji przeżytych i szkodliwych, podważaniu autorytetów, (…) ciągłym niepokoju i poszukiwaniu, na równoczesnej penetracji stanu aktualnego, jego genezy i perspektyw”. Autor przygotował książkę w nieco innej formule. Swój niepokój o przyszłość wychowania fizycznego przedstawił w opowieściach, co nadaje pracy oryginalności. Józefa Węglarza można zaliczyć do grona nielicznych autorów, którzy subiektywnie, z odrobiną sarkazmu i humoru, odsłaniają słabości fizycznej edukacji. Jednocześnie, wykorzystując wieloletnie doświadczenie, Autor podpowiada jak dany problem rozwiązać.…

The reviewed book is included in the reading list showing the problems of school physical education and looking for their effective solution. The preparation of such a study consists, as Maciej Demel (1973, p. 7) wrote, ‘in critically attacking the present, overcoming outdated and harmful traditions, undermining authorities, (...) constant anxiety and searching, simultaneous penetration of the current state, its origins and prospects.’ The author has prepared the book in a slightly different formula. He presented his anxiety about the future of physical education in stories, which gives the work originality. Józef Węglarz can be counted among the few authors who subjectively, with a bit of sarcasm and humor, reveal the weaknesses of physical education. At the same time, using many years of experience, the author suggests how to solve a given problem…

Problem identification: The desire for motherhood is one of the top priorities for most female young cancer survivors. The risk of infertility after cancer therapy is an important concern with several physical and emotional consequences. This comprehensive literature review aims to summarize and contextualize recent research that has been carried out on female fertility after cancer, suggesting future research and clinical directions. Literature search: Searches included the keywords “cancer”, “female”, “adults”, and “fertility”. Studies were selected if focused on infertility issues in female cancer survivors. Data synthesis: Eight themes were identified: the effects of anticancer treatments on fertility; fertility preservation methods; international recommendations regarding infertility risk; health professionals’ attitudes towards fertility preservation; patient’s concerns regarding the risk of infertility; patients' information needs; and the impact of the risk of infertility in patient’s quality of life. Conclusions: Psycho-oncologists should be integrated in the oncofertility teams to assess patients’ needs before cancer treatment initiation.

MicroRNAs (miRNAs) are small non-coding, single-stranded RNAs (19–25 nucleotides long) that regulate expression of multiple target genes, predominantly by binding to the 3′ untranslated region of messenger RNA (mRNA) transcripts, resulting either in translational inhibition or mRNA degradation. miRNAs are found in many bodily fluids, including plasma and serum, and are protected from degradation in the circulation through association with lipids, proteins, or microparticles, making them attractive disease biomarker candidates. Circulating levels of cardiac miRNAs (including miR-1, miR-133a, miR-208a, miR-208b, and miR-499) have been frequently reported as elevated in both coronary heart disease (CHD) and heart failure (HF) and have been proposed as candidate biomarkers that reflect the severity of myocardial injury. Subsequent large, array-based screening studies comparing patients and controls have identified altered expression of additional miRNAs, not just those of cardiac origin. However, among these studies there has been little consensus as to which miRNAs are top candidates for diagnosis or prognosis in either CHD or HF. The measurement of circulating miRNAs is further complicated by the timing of collection, especially after acute cardiac events while miRNA levels in blood may be rapidly changing; confounding influences from medications or contaminating blood cells at the time of sampling; and the need for standardization of normalization strategies. This review evaluates recent developments in the identification of circulating miRNAs as markers for diagnosis and prognosis in CHD and HF, and the methodological issues in measurement of circulating miRNAs.

Maxillofacial bone diseases represent a heterogeneous group involving benign and malign tumors, and metabolic, malformative, and infectious diseases. They have a tendency to relapse even with a good initial treatment. Therefore, we need to start with active surveillance based on medical imaging (CT scanner). The treatment of maxillofacial bone diseases is based mainly on clinical examination, radiological findings, and pathological diagnosis. The treatment consists of curettage or maxillary/mandibulary interruptive or not-interruptive bone resection. Development of guidelines seems impossible due to the heterogenicity of clinical presentations. The individualized treatment should prevail.

Plusieurs pathologies osseuses des maxillaires ont comme caractéristique une tendance à la récidive, et ce même après un traitement approprié. Il convient donc de les reconnaître afin de pouvoir les surveiller, à la fois cliniquement et par une technique d’imagerie appropriée. On distinguera ici des pathologies tumorales bénignes et malignes, métaboliques, malformatives et infectieuses. Actuellement, le CT scan est la technique d’imagerie médicale de premier choix pour établir le diagnostic différentiel et permettre la surveillance de ces pathologies osseuses. Le traitement de ces pathologies récidivantes est soit le curetage/énucléation si possible (corticales non rompues) soit une résection interruptrice ou non des maxillaires ou de la mandibule, et ce en fonction des données cliniques et surtout anatomopathologiques à discuter et envisager au cas par cas, la généralisation dans ce domaine étant impossible voire dangereuse pour le patient. Il ne peut donc être question de proposer des recommandations ni des algorithmes décisionnels.

Prion diseases or transmissible spongiform encephalopathies are a group of neurodegenerative disorders characterized by a widespread deposition in the central nervous system, and some other tissues, of the pathological isoform of the prion protein (PrPd; “d” from disease). TSEs include: 1) kuru; 2) Creutzfeldt-Jakob disease (CJD), the disease that occurs in four etiologically forms: • sporadic CJD (sCJD), • familial CJD (fCJD), • iatrogenic CJD (iCJD), • variant CJD (vCJD); 3) Gerstmann-Sträussler-Scheinker disease (GSS); 4) fatal familial insomnia (FFI). There are also several TSEs in animals: – scrapie – in sheep, goats and moufflons; – bovine spongiform encephalopathy (BSE) and bovine atypical spongiform encephalopathy (BASE) or mad cow disease; – BSE passaged to: • domestic cats (feline spongiform encephalopathy, FSE) and large cats (lion, tiger, cheetah, ocelot and puma) • antelopes (kudu, nyala, oryx), bison; – chronic wasting disease in mule deer and elk; – transmissible mink encephalopathy in ranch-reared mink. Historically, the eponimic names are also included: atactic type of CJD or Betty Brownell syndrome, CJD with a cortical blindness (Heidenhain type) and the panencephalopathic type (Tateishi). The amyotrophic type is not TSE but motor neuron disease with dementi. In 1996, a new variant CJD (now only vCJD) was discovered as a result of a passage from BSE to humans.

Choroby wywołane przez priony (prion diseases) lub pasażowalne encefalopatie gąbczaste (transmissible spongiform encephalopathies, TSE) to grupa chorób neurozwyrodnieniowych charakteryzująca się odkładaniem w ośrodkowym układzie nerwowym i w niektórych innych tkankach patologicznej izoformy białka prio-nu, PrPd (prion protein). U ludzi do grupy tej zalicza się: 1) kuru; 2) chorobę Creutzfeldta-Jakoba (Creutzfeldt-Jakob disease, CJD), która występuje w czterech postaciach: • sporadycznej CJD (sCJD), • rodzinnej CJD (fCJD, od familial), • jatrogennej CJD (jCJD), • wariancie CJD (vCJD); 3) chorobę Gerstmanna-Strausslera-Scheinkera (GSS); 4) śmiertelną rodzinną bezsenność (fatal familial insomnia, FFI). U zwierząt występuje kilka chorób niebędących przedmiotem niniejszego opracowania: - scrapie - u owiec, kóz i muflonów; - pasażowalna encefalopatia bydła (bovine spongiform encephalopathy, BSE) i atypowa BSE (bovine atypical spongiform encephalopathy, BASE) lub „choroba szalonych krów” (mad cow disease); - BSE przepasażowana na: • koty domowe (feline spongiform encephalopathy, FSE), lwa, tygrysa, geparda, ocelota i pumę, • egzotyczne gatunki antylop (m.in. kudu, nyala, oryks), bizona; - przewlekła choroba wyniszczająca (chronic wasting disease, CWD) u małych jeleni i jelenia wapiti w USA; - pasażowalna encefalopatia norek. Historycznie w obrębie CJD wyróżnia się eponimiczne zespoły: ataktyczny (Betty Brownell), ze ślepotą korową (Heidenhaina) i panencefalopatyczny (Tateishi). Typ amiotroficzny jest to stwardnienie zanikowe boczne z otępieniem, aczkolwiek w przypadkach CJD o długim przebiegu zajęcie motoneuronu dolnego (amio-trofia) jest relatywnie częste. W 1996 roku wyróżniono tzw. nowy wariant CJD (nvCJD; obecnie wariant CJD, vCJD), będący wynikiem przepasażowania choroby szalonych krów (encefalopatii gąbczastej bydła, bovine spongiform encephalopathy, BSE) na człowieka.

Corynebacterium diphtheriae (C. diphtheriae) is the primary pathogen causing diphtheria, which basically exists in two forms: nasopharyngeal and cutaneous. According to a commonly introduced vaccination programme against diphtheria, pertussis and tetanus (DPT), the incidence of diphtheria has significantly dropped around the world, in some areas disappearing almost completely. However nowadays, we observe the reappearance of diphtheria, especially the cutaneous form, even in countries with very high vaccination rates due to the increasing migration from countries with a lower level of vaccinated citizens. We present a case study of a Ukrainian immigrant diagnosed with cutaneous diphtheria to raise the awareness of the medical community about this returning disease, its cutaneous form and new medical challenges connected to it. It has been the first reported case of C. diphtheriae infection in Poland since 2005. We analysed the most recent articles available in PubMed and Google Scholar databases using criterion keywords such as: “diphtheria case”, “diphtheria case report”, “cutaneous diphtheria”. We selected the most suitable out of approximately 1,700 articles. The presented case report and analysis of scientific publications on cutaneous diphtheria show the importance of this form of the disease in the modern, post-vaccination era. We claim that the importance of vaccination, self-protection during contact with patients, and awareness of the risks of the medical environment are becoming even more important.

Corynebacterium diphtheriae (C. diphtheriae) jest pierwotnym patogenem wywołującym błonicę, która zasadniczo występuje w dwóch postaciach: nosowo-gardłowej i skórnej. W związku z powszechnymi szczepieniami przeciwko błonicy, krztuścowi i tężcowi (diphtheria, pertussis and tetanus – DPT) częstość występowania błonicy na świecie znacząco zmalała, na niektórych obszarach zanikając niemal całkowicie. W dzisiejszych czasach ponownie obserwujemy przypadki błonicy, zwłaszcza postaci skórnej, nawet w krajach z wysokim wskaźnikiem wyszczepienia, w związku z nasilającą się migracją z krajów o niższym odsetku zaszczepionych obywateli. Prezentujemy studium przypadku ukraińskiego imigranta ze zdiagnozowaną błonicą skóry, by zwiększyć świadomość środowiska medycznego o tej powracającej chorobie, jej postaci skórnej oraz związanych z tym nowych wyzwaniach. To pierwszy zaraportowany przypadek zakażenia C. diphtheriae w Polsce od 2005 r. Przeanalizowano najnowsze artykuły dostępne w bazach PubMed i Google Scholar, używając jako kryterium następujących słów kluczowych: „błonica przypadek”, „błonica opis przypadku”, „błonica skóry”. Wybrano artykuły o najwyższej korelacji z ponad 1700 wyników wyszukiwania. Opis przypadku i analiza publikacji naukowych na temat błonicy skóry pokazują znaczenie tej postaci choro-by w nowej, poszczepiennej erze. Twierdzimy, że szczepienia, stosowanie ochrony osobistej podczas kontaktu z pacjentem oraz świadomość środowiska medycznego dotycząca możliwych zagrożeń stają się jeszcze bardziej istotne.
