Cancer of Unknown Primary Origin (CUPO) is defined by the presence of metastatic lesions, diagnosed by means of cytological or pathological evaluation, for which no primary site can be detected during a thorough examination. The clinical investigation, directed at locating the site of the neoplastic lesion, is determined by the results of laboratory tests, imaging procedures, and pathological examinations. It is also essential to conduct a complete medical history and thorough physical examination. The detection of the primary site allowed to introduce specific therapy, which can offer clinical benefits, considering a favorable prognosis. The aim of the study was to assess the range of diagnostic procedures performed in patients with CUPO and efficacy in identifying the primary lesion. Material and methods. Retrospective analysis comprised a group of 29 patients with CUPO, operated between January, 2002 and December, 2011, at the Department of Surgical Oncology, Medical University in Łódź. The study group comprised 16 male and 13 female patients; median age at presentation was 58.3 years (ranging between 30-79 years). Results. Detailed diagnostic management depending on the location of metastatic lesions and their histological type was performed in 20 of the 29 study patients (69%). Considering the remaining 9 (31%) patients detailed diagnostics was not performed, due to the patients' poor general condition. In 55% (11/20) of patients subject to detailed diagnostics, the primary neoplastic lesion was determined. Conclusions. Considering the study group, most patients with cancer of unknown primary origin were characterized by a favorable prognosis, which justified thorough diagnostics, in order to establish the primary neoplastic lesion. The introduction of diagnostic examinations enabled to identify the primary site of the tumor in more than 50% of patients. With the development of imaging methods one can expect improvement of unsatisfactory results, considering the detection of primary neoplastic foci.

Ultrabiomicroscopic (UBM) examination is a powerful diagnostic tool that can assist in the management and treatment of many patients. It is especially helpful in the case of glaucoma and damage to the optic nerve. We can successfully treat patients only if we are aware of the disease cause. Although UBM examination cannot replace a complete clinical examination (including dynamic gonioscopy), it is a great supplement that can confirm many diagnoses.

PL

Badanie ultrabiomikroskopowe to silne narzędzie diagnostyczne, które może pomóc w prowadzeniu i leczeniu wielu pacjentów. Jest szczególnie pomocne w przypadku jaskry, gdyż nie zawsze patomechanizm powstawania zmian jest znany, a uszkodzenie nerwu wzrokowego często postępuje. Będąc świadomym przyczyny, można skutecznie leczyć pacjenta. Samo badanie UBM nie może jednak zastąpić pełnego badania klinicznego, włącznie z wykonaniem gonioskopii dynamicznej. Jest ono świetnym uzupełnieniem, które może potwierdzić wiele postawionych diagnoz.

Malignant lymphomas represent approximately 5% of all malignant neoplasm of the head and neck and may involve nodal or extranodal sites. The head and neck region is the second most frequent anatomical site of extranodal lymphomas (after the gastrointestinal tract). Most are non-Hodgkin lymphomas (NHL) of B-cell lineage. Hodgkin's lymphoma (HL) rarely occurs in extranodal site.The aim of the study was to evaluate head and neck manifestation of lymphoma (both HL and NHL) and emphasize diagnostic difficulties of these pathologies.Material and methods. Retrospective review of medical records of patients diagnosed for lymphomas in our department was performed. Authors analyzed demographic data as well as clinical manifestation and diagnostic trials.Results. 9 patients were included to the study. 7 of them suffered from extranodal NHL and 2 of them from HL (one patient - extranodal and one nodal manifestation). There were diagnostic complications in all cases and final diagnosis was made after surgical material analysis.Conclusions. This data demonstrate low sensivity of fine needle aspiration for identification of lymphoma as well as clinical picture is non characteristic.

Intraoperative ultrasound (IOUS) allows confirming and verifying the preoperative diagnosis. In many cases it allows correct determination of the severity of the disease, safe surgery performance and shortening its duration. Proper assessment of anatomic structures during the surgery and evaluation of the operating field after the treatment termination, in combination with their ultrasound evaluation that permits more complete assessment of radical treatment. The aim of the study was to define current indications for the use of intraoperative ultrasound in the treatment of pancreatic lesions, based on our own experience and the cited literature. Material and methods. The Clinic, where the authors work, uses intraoperative ultrasound in everyday practice. In this paper we try to share our experience in this imaging technique. Studies were compared before the procedure both in the ultrasound and CT examination rooms with the images obtained intraoperatively. Intraoperative examination was performed by the surgeon who performed assessment before the procedure, what enabled verification of diagnoses. Presented material refers to 102 IOUS procedures performed during laparotomy due to pancreatic lesions. Results and conclusions. IOUS is a reliable test for the evaluation of both inflammatory and acute lesions in the pancreas during the surgery of chronic, symptomatic pancreatitis. It correctly determines the extent of the planned surgery. In the case of pancreatic cancer it verifies local severity of the tumour lesions, assessing involving of the peripancreatic vessels, lymph nodes and the presence of local and distant metastases, including those in the liver. IOUS proved highly effective in the evaluation of endocrine and cystic pancreatic tumours. The study significantly improves the effectiveness of intraoperative BAC and aspiration or drainage of fluid reservoirs

Renal artery aneurysms are the second most common visceral artery aneurysms after splenic artery aneurysms, and before hepatic artery aneurysms. The study presented a case of a ruptured giant right renal artery aneurysm in a female patient. The presented case is worth mentioning, due to the giant size of the lesion. The diameter of the aneurysm exceeded 10 cm. Available literature data mentioned single reports of such large aneurysms located in the renal arteries. In spite of the fact that renal artery aneurysms are the second most common visceral artery aneurysms, their management is accompanied by some controversy. Literature data mentioned the dominance of endovascular techniques. However, surgical treatment remains to be the most effective and radical method.

Background: The purpose of this study was to design a factor model whose application would refine the diagnostics of actual and continuous states in ice hockey players.Material/Methods: The following batteries of tests were used: Test battery 1 serves as a monitoring tool for the Methods Department of Slovak Ice Hockey Federation. Test battery 2 was designed on the basis of previous empirical evidence. A comparative analysis of the batteries was aimed at the qualitative aspect of the criteria of the individual test items.Results: The results showed partial incompleteness of the battery and a need to complement the battery with test items that would be more indicative of skating performance. The saturation of five factors within test battery 2 demonstrated a hierarchy of individual parameters, which were actually indicative of skating performance.Conclusions: With a high degree of probability, one may conclude the incidence of a common base of running parameters (factor model 1), which despite a different character of loading shared an identical base. This contradiction represents a certain knowledge paradox indicating that the implementation of these items into the test battery does not sufficiently assess general fitness in ice hockey players making their number redundant.

Glycosylation is a form of post-translational modification of proteins and occurs in every living cell. The carbohydrate chains attached to the proteins serve various functions. There are two main types of protein glycosylation: N-glycosylation and O-glycosylation. In this paper, we describe the O-glycosylation process and currently known congenital disorders of glycosylation associated with defects of protein O-glycosylation. This process takes place in the cis Golgi apparatus after N-glycosylation and folding of the proteins. The O-glycosylation is essential in the biosynthesis of mucins, the formation of proteoglycan core proteins and blood group proteins. Most common forms of O-glycans are the mucin-type glycans. There are more than 20 known disorders related to O-glycosylation disturbances. We review 8 of the following diseases linked to defects in the synthesis of O-xylosylglycans, O-N acetylgalactosaminylglycans, O-xylosyl/N-acetylglycans, O-mannosylglycans, and O-fucosylglycans: multiple exostoses, progeroid variant of Ehlers-Danlos syndrome, progeria, familial tumoral calcinosis, Schneckenbecken dysplasia, Walker-Warburg syndrome, spondylocostal dysostosis type 3, and Peter's plus syndrome. Causes of these diseases include gene mutations and deficiency of proteins (enzymes). Their diagnosis includes syndromic presentation, organ-specific expression and laboratory findings.

Glycosylation is the most common chemical process of protein modification and occurs in every living cell. Disturbances of this process may be either congenital or acquired. Congenital disorders of glycosylation (CDG) are a rapidly growing disease family, with about 50 disorders reported since its first clinical description in 1980. Most of the human diseases have been discovered recently. CDG result from defects in the synthesis of the N- and O-glycans moiety of glycoproteins, and in the attachment to the polypeptide chain of proteins. These defects have been found in the activation, presentation, and transport of sugar precursors, in the enzymes responsible for glycosylation, and in proteins that control the traffic of component. There are two main types of protein glycosylation: N-glycosylation and O-glycosylation. Most diseases are due to defects in the N-glycosylation pathway. For the sake of convenience, CDG were divided into 2 types, type I and II. CDG can affect nearly all organs and systems. The considerable variability of clinical features makes it difficult to recognize patients with CDG. Diagnosis can be made on the basis of abnormal glycosylation display. In this paper, an overview of CDG with a new nomenclature limited to the group of protein N-glycosylation disorders, clinical phenotype and diagnostic approach, have been presented. The location, reasons for defects, and the number of cases have been also described. This publication aims to draw attention to the possibility of occurrence of CDG in each multisystem disorder with an unknown origin.

Besides their structural catalytic and diverse regulatory functions, proteins are also precursors of many important biological compounds essential for normal functioning of humans. Many of these compounds may be used as markers for identification of specific pathological states. A comprehensive knowledge about the metabolism of salivary proteins and the mechanisms of action of their metabolites allowed the development of effective treatment for many disorders. However, it should not be forgotten that in some pathological conditions, these compounds not only could be involved in the pathogenesis but also could be used as tool in the prediction of many diseases. This paper is a review of the published literature on selected salivary proteins in the context of the physiological processes of the human body and chosen chronic disorders, such as diabetes, diabetic nephropathy, mucositis, oral mycoses and caries.

Computed tomographic colonography (CTC) has the potential to become an accepted technique for detecting of colorectal cancer.The aim of the study was to evaluate usefulness of CTC in preoperative evaluation of colorectal tumors and the regions of colon endoscopically unavailable.Material and methods. A total of 49 patients with colorectal tumors identified at conventional colonoscopy were included. In all these patients CTC was performed and results were compared with colonoscopy. In addition in CTC infiltration of surrounding tissues, organs, lymph nodes and liver were assessed. Findings were compared with contrast-enhanced CT of abdomen.Results. Colonoscopy was completed to the caecum in 24 (48.9%) patients. CTC failed only in one patient. CTC was congruent with colonoscopy in evaluation of tumor location and morphological type. In CTC two additional tumors were found proximately to occlusive masses, it is in endoscopically unavailable regions. Sensitivity and specificity of CTC comparing to CT in diagnosis of fat tissue infiltration and surrounding organs infiltration at the site of tumor were 95.5% / 50% and 100% / 86.9% respectively. Concordance of results in evaluation of lymph nodes was 93.9% while sensitivity and specificity for CTC was 84.6% and 100% respectively. Concordance of evaluation of liver metastases was 78.8%, while sensitivity and specificity for CTC was 61.5% and 90% respectively.Conclusions. CTC is a useful method in diagnostics of colorectal tumors. It allows to diagnose tumor, determine local tumor staging and detect synchronous lesions in endoscopically unavailable regions.

Introduction: The aim of the study was to present selected cases with Eagle’s syndrome diagnosed and treated at the Department of Otolaryngology, Laryngological Oncology, Audiology and Phoniatrics, Medical University of Lodz, in the years 2016–2020. Material and method: Five selected clinical cases with Eagle’s syndrome are presented, including three male patients and two female patients, aged 28 to 42 years. Results: The prevalence of Eagle’s syndrome was similar for both female and male patients. The carotid artery syndrome, which is characterized by: visual disturbances, unilateral pain located along cervical vessels, headache and migraine, was more common. Lack of proper diagnosis of Eagle’s syndrome often significantly delays the implementation of proper treatment and thus exposes patients to long-term struggle with pain. Our observations have shown that the time between the onset of symptoms and correct diagnosis in patients averaged about five years. 3D-CT scan is the gold standard for detecting Eagle’s syndrome. An intraoral approach was used in surgical treatment. Although this approach offers shorter treatment time and better cosmetic effect, there is also a greater risk of complications associated with limited visibility of the surgical field and infection. Conclusions: Although styloid syndrome usually occurs bilaterally, these patients reported unilateral symptoms. No correlations were found between the prevalence of Eagle’s syndrome and sex, the length of the styloid process or age, nor side of the body. The best healing effect is obtained by surgical correction/reduction of the elongated styloid process.

Early diagnosis of cystic fibrosis (CF) made by the introduction of CF NBS (Cystic Fibrosis Newborn Screening) provides the opportunity to undertake preventive measures and provide treatment before the development of irreversible changes in the respiratory tract and other complications. CF NBS was conducted as a pilot programme in four Polish districts in the period 1999-2003. In 2006 CF NBS started again and was gradually extended across the country. The aim of this study was to show the evolution of the Polish CF NBS strategies and assess the diagnostic consequences of this programme. Material and methods: The study involved children diagnosed and treated only in the IMiD Centre. The strategy in Polish CF NBS was modified over time. Firstly, the model IRT/IRT and IRT/IRT/DNA with one mutation was implemented, which was followed by IRT/DNA with a gradually expanding number of CFTR mutations (tab. I). Newborns with positive results of CF NBS were called to the CF IMiD Centre, and sweat tests were performed. The children diagnosed and children with mutations in both alleles of the CFTR gene (even if at least one of them had undefined pathogenicity) were taken under IMiD Centre care. Sensitivity, specificity and positive predictive values during subsequent stages of CF NBS were calculated (tab. III). Results: During the 1999-2003 pilot study 444 063 newborns underwent CF NBS and in 74 cases CF was diagnosed. 582 693 newborns were screened from September 2006 to December 2011 in four regions and 100 children were diagnosed with CF. The frequencies of CF in the Polish population in both screening periods were 1:5767 and 1:5712 respectively. Firstly, the IRT/IRT model was implemented, but the number of newborns called to the CF Centre was high - the PPV was 7.6%. In the next step CF NBS DNA analysis was used. Here sensitivity and specificity were high − nearly 100%. In the following years the number of mutations detected was expanded (including 16 most common ones in the Polish population). Due to the panel changes, the number of calls declined and the PPV (predictive positive value) improved (to 26.1%) after the application of expanded genetic analysis. Expanding the panel of mutations resulted in an increased number of carriers and observational subjects. Conclusions: IRT/DNA strategy with expanded DNA analysis provides the opportunity for earlier CF diagnosis even in children with normal sweat test values. However, this model caused frequent carrier detection and inconclusive diagnosis in comparison to IRT/IRT or IRT/IRT/DNA with a limited number of mutations. Further research and changes in Polish CF NBS are needed to increase the PPV, while preserving high sensitivity and specificity. Key words: diagnostics, newborn screening, cystic fibrosis

Wczesne rozpoznanie mukowiscydozy dzięki wprowadzeniu CF NBS (Cystic Fibrosis Newborn Screening) daje możliwość podjęcia działań profilaktycznych i leczniczych przed powstaniem nieodwracalnych zmian w układzie oddechowym oraz innych powikłań. W latach 1999-2003 prowadzono pilotażowy CF NBS na terenie czterech polskich województw. W 2006 roku wznowiono program na tym samym obszarze, a od czerwca 2009 roku jest on prowadzony w całym kraju. Celem pracy było przedstawienie ewolucji algorytmów diagnostycznych, według których prowadzono w Polsce badanie przesiewowe noworodków w kierunku mukowiscydozy oraz ich przydatności diagnostycznej. Materiał i metody: Praca dotyczy dzieci, u których diagnostyka i leczenie prowadzone było w Instytucie Matki i Dziecka. W trakcie prowadzenia polskiego CF NBS algorytm diagnostyczny ulegał modyfikacji. Początkowo wdrożono schemat IRT/IRT oraz IRT/IRT/DNA z oznaczeniem jednej mutacji, Następnie wprowadzono schemat IRT/DNA ze stopniowo rozszerzanym panelem mutacji genu CFTR (tab. I). Dzieci z nieprawidłowym wynikiem CF NBS wzywane były na wizytę weryfikacyjną. podczas której wykonywano testy potowe. Dzieci, u których potwierdzono chorobę lub gdy stwierdzano mutacje w obu allelach genu CFTR (nawet jeśli przynajmniej jedna z nich była mutacją o nieznanych lub niejednoznacznych konsekwencjach klinicznych), pozostawały pod opieką IMiD. Czułość, swoistość oraz wartość predykcyjną dodatnią (PPV) obliczono dla poszczególnych etapów prowadzenia CF NBS (tab. III). Wyniki: W okresie prowadzenia badania pilotażowego (1999-2003) zbadano 444 063 noworodków, u 74 rozpoznano CF. W latach 2006-2011 na terenie województw mazowieckiego, warmińsko- -mazurskiego, podlaskiego i lubelskiego zbadano 582 693 noworodki i rozpoznano CF u 100 dzieci. Częstość występowania mukowiscydozy w populacji polskiej w obu okresach, w których prowadzony był przesiew, wynosiła odpowiednio 1:5767 oraz 1:5712. Początkowo stosowano schemat IRT/IRT. Skutkiem była duża liczba wezwań na wizyty weryfikacyjne i niskie PPV – 7,6%. Dołączenie analizy DNA do CF NBS pozwoliło na uzyskanie wysokiej czułości i swoistości bliskiej 100%. W kolejnych latach prowadzenia CF NBS poszerzono panel analizy DNA uwzględniający wykrywanie 16 najczęściej występujących w polskiej populacji mutacji genu CFTR, stopniowo zwiększając liczbę mutacji rzadziej występujących. Dzięki temu zmniejszyła się liczba wezwań do ośrodka na wizyty weryfikacyjne, Najwyższe PPV – 26,1% uzyskano po zastosowaniu rozszerzonej analizy genetycznej. Rozszerzanie panelu analizy molekularnej przyczyniło się do wzrostu liczby przypadków obserwacyjnych. Wnioski: Na podstawie przedstawionych wyników można wnioskować, że zastosowanie schematu IRT/DNA z rozszerzonym panelem analizy DNA daje możliwość wczesnego rozpoznania CF nawet u dzieci z prawidłowymi wartościami testów potowych. Jednakże zastosowanie tego modelu powoduje zwiększenie liczby przypadków wymagających obserwacji w porównaniu do używanego uprzednio schematu IRT/IRT lub IRT/IRT/DNA z ograniczonym panelem mutacji. Potrzebne są dalsze badania oraz wprowadzenie zmian w polskim CF NBS, tak aby zwiększyć PPV utrzymując wysoką czułość iswoistość.

INTRODUCTION: Acute coronary syndromes are one of the leading causes of death due to cardiovascular diseases. The diagnosis is made on the basis of the clinical picture, ECG record and laboratory tests. Diagnosis of critical myocardial ischemia in pre-hospital conditions is a challenge for emergency medical teams. MATERIAL AND METHODS: In order to determine the level of knowledge and the ability to recognize and deal with patients with acute coronary syndrome tests were carried out among fifty employees of the emergency medical service (doctors, nurses and paramedics) in the region of central Poland. Statistical analysis was carried out using the normality test of the Shapiro-Wilk distribution and non-parametric chi-square test of independence. The results were considered significant at the level p < 0,05. RESULTS: In the field of diagnostics, doctors obtained the result of 73.20% (SD ± 32.23), paramedics: 52.00% (SD ± 24.51), and nurses: 30.00% (SD ± 13.75). Correct treatment was best implemented by paramedics who obtained an average of 51.11% (SD ± 34.98). In turn, doctors gave 49.33% (SD ± 39.05) correct answers, and nurses 43.22% (SD ± 34.17). There was no statistical dependence of the test results on the profession (ᵡ² = 1.13; p> 0.05), nor being the head of the emergency medical team (ᵡ² = 0,43; p>0,05). CONCLUSIONS: The level of preparation of ambulance service personnel in the field of identifying and dealing with patients with suspected acute coronary syndrome is insufficient. Further research is indicated indicating the greatest substantive deficiencies of emergency doctors, paramedics and emergency nurses to implement the necessary professional development.

Rozpoznanie krytycznego niedokrwienia mięśnia sercowego w warunkach przedszpitalnych stanowi wyzwanie dla zespołów ratownictwa medycznego. MATERIAŁ I METODY: W celu określenia poziomu wiedzy i umiejętności rozpoznawania oraz postępowania z pacjentem z ostrym zespołem wieńcowym przeprowadzono testy wśród pięćdziesięciu pracowników systemu Państwowego Ratownictwa Medycznego (lekarzy, pielęgniarek i ratowników medycznych) w rejonie centralnej Polski. Analizę statystyczną przeprowadzono za pomocą testu normalności rozkładu Shapiro-Wilka oraz testu nieparametrycznego chi-kwadrat niezależności. Wyniki uznano za istotne na poziomie p < 0,05. WYNIKI: W zakresie diagnostyki lekarze uzyskali wynik 73,20% (SD ± 32,23), ratownicy medyczni: 52,00% (SD ± 24,51), a pielęgniarki: 30,00% (SD ± 13,75). Poprawne postępowanie najlepiej potrafili wdrożyć ratownicy medyczni, którzy uzyskali średnią 51,11% (SD ± 34,98). Z kolei lekarze udzielili 49,33% (SD ± 39,05) poprawnych odpowiedzi, zaś pielęgniarki 43,22% (SD ± 34,17). Nie wykazano zależności statystycznej wyników testu z wykonywanym zawodem (ᵡ² = 1,13; p>0,05), ani pełnieniem funkcji kierownika zespołu ratownictwa medycznego (ᵡ² = 0,43; p>0,05). WNIOSKI: Poziom przygotowania personelu zespołów ratownictwa medycznego w zakresie rozpoznawania i postępowania z pacjentem z podejrzeniem ostrego zespołu wieńcowego jest niewystarczający. Wskazane są dalsze badania wskazujące na największe braki merytoryczne lekarzy systemu, ratowników medycznych i pielęgniarek systemu, aby wdrożyć niezbędne doskonalenie zawodowe.

Inferior vena cava leiomyosarcoma is a malignant neoplasm rarely diagnosed. The study presented two cases of inferior vena cava leiomyosarcomas subject to treatment at the Department of Oncology, Center of Oncology in Warsaw. The first patient underwent surgery after a two-year thorough gastroenterological diagnostic process, being suspected of pancreatic cancer. Proper diagnosis was established intraoperatively, the tumor was completely excised. After ten months the patient was subject to chemotherapy, due to the presence of distant metastatic lesions. Chemotherapy was stopped after 24 months, due to disease progression. The patient died six months, thereafter. The second patient underwent surgery after a short diagnostic process, being suspected of an adrenal gland tumor. Proper diagnosis was established intraoperatively, and the tumor was completely excised. The patient remained under close oncological control. Three years after the procedure disease recurrence was not observed. Retroperitoneal space tumors pose a significant clinical problem. Rapid diagnosis and proper therapeutic decisions often determine the future of such patients. The five-year survival rate of patients subject to radical surgical treatment, due to inferior vena cava leiomyosarcomasa ranges between 33 and 55%.
