Objective: Approximately one third of patients diagnosed with muscle-invasive urinary bladder cancer (UBC) have undetected metastases at the time of treatment of the primary tumor. Currently there are no reliable specific serum markers for monitoring and evaluating risk profiles of urothelial cancers. Several studies suggest that detection of circulating tumor cells (CTCs) may correlate with the disease status and prognosis at baseline and early in the treatment of cancers. In this study a new way of isolation and in vitro cultivation of CTCs of urinary bladder cancer was introduced. Materials and methods: Peripheral blood (PB) samples from 53 patients who had undergone urological procedure were evaluated using the MetaCell device (MetaCell s.r.o., Ostrava, Czech Republic). The patients enrolled in the study were both oncological patients with UBC and non-oncological patients with inflammation (14 patients). The sensitivity and quantification of CTCs were evaluated. The separated CTCs were cultured in vitro. Results: 39 patients with confirmed UBC were enrolled in the study. CTCs were detected in 25 (64%) patients, and most of these patients had between 6 and 10 cells. The separated CTCs were successfully cultured in vitro. Conclusion: CTCs were detected in a higher percentage of patients than in other studies. This paper describes the first successful culturing of human UBC cells. The MetaCell approach used in this study enabled the capture of viable intact virgin CTCs (virgin CTC) suitable for next in vitro culturing, single cell analysis or drug testing.

Following absorption, polychlorinated biphenyls (PCBs) bind to albumin and are transported via blood into the target tissues. PCBs then accumulate in tissues and induce a variety of harmful chronic and developmental effects. The aim of the present study is to determine binding parameters, such as binding constant, quenching constant, and number of binding sites for three PCB congeners (PCB118, PCB126 and PCB153) in complex with human serum albumin (HSA). The binding parameters for the complexes of HSA-PCB118, HSA-PCB126, and HSA-PCB153 excited at 280 nm were compared with those excited at 295 nm. Quenching (static and dynamic) of HSA fluorescence was analyzed based on the Stern-Volmer method. Binding (Ka) constants were calculated according to the Scatchard method and analysis of non-linear regression was based on a two-component model with the Lavenberg-Marquardt algorithm. For all analyzed complexes, a single independent class of binding site for PCB congeners was found in HSA subdomain IIA. Tyrosine residues appear to play the most prominent role in binding of PCB126 to HSA, while tryptophan-214 played a dominant role in interactions of PCB153 with HSA. Among studied PCB congeners, PCB118 formed the most stable complexes with HSA. These results illustrate the importance of studies targeting the binding of PCBs to serum albumin as part of the strategy to understand and protect against toxicity of these environmental toxicants. © 2014 Published by Elsevier B.V.

Aim. The aim of this open-label study was to assess extracranial Doppler criteria of chronic cerebrospinal venous insufficiency in multiple sclerosis patients. Methods. Seventy patients were assessed: 49 with relapsing-remitting, 5 with primary progressive and 16 with secondary progressive multiple sclerosis. The patients were aged 15-58 years and they suffered from multiple sclerosis for 0.5-40 years. Sonographic signs of abnormal venous outflow were detected in 64 patients (91.4%). Results. We found at least two of four extracranial criteria in 63 patients (90.0%), confirming that multiple sclerosis is stronghly associated with chronic cerebrospinal venous insufficiency. Additional transcranial investigations may increase the rate of patients found positive in our survey. Reflux in internal jugular and/or vertebral veins was present in 31 cases (42.8%), stenosis of internal jugular veins in 61 cases (87.1%), not detectable flow in internal jugular and/or vertebral veins in 37 cases (52.9%) and negative difference in cross-sectional area of the internal jugular vein assessed in the supine vs. sitting position in 28 cases (40.0%). Flow abnormalities in the vertebral veins were found in 8 patients (11.4%). Pathologic structures (membranaceous or netlike septa, or inverted valves) in the junction of internal jugular vein with brachiocephalic vein were found in 41 patients (58.6%), in 15 patients (21.4%) on one side only and in 26 patients (37.1%) bilaterally. Conclusion. Multiple sclerosis is highly correlated with chronic cerebrospinal venous insufficiency. These abnormalities in the extracranial veins draining the central nervous system can exist in various combinations. The most common pathology in our patients was the presence of an inverted valve or another pathologic structure (like membranaceous or netlike septum) in the area of junction of the IJV with the brachiocephalic vein.

Aim Abdominal pain, defaecation disorder and change of bowel habit are the commonest symptoms of irritable bowel syndrome (IBS). The effect of microencapsulated sodium butyrate (MSB) was assessed on the severity of symptoms in patients with IBS. Method Sixty-six patients treated with one of the standard pharmacological therapies for at least 3months were included in the study. They were randomized to receive MSB as a supplemental treatment to standard therapy or to receiving a placebo. Previous pharmacological therapy was continued throughout the study in both arms. Clinical evaluation was performed at baseline, 4 and 12weeks. Each assessment was documented by a validated visual analogue score questionnaire measuring the severity of selected clinical symptoms, a closed-end questionnaire measuring the frequency of selected clinical symptoms and a single closed-end question measuring the subjective improvement of symptoms. Results After 4weeks there was a significant decrease of pain during defaecation in the MSB group which extended to improvement of urgency and bowel habit at 12weeks. Reduction of abdominal pain, flatulence and disordered defaecation was not statistically significant. Conclusions MSB as a supplemental therapy can reduce the frequency of selected clinical symptoms in patients with IBS, without significant influence on reducing symptom severity. © 2012 The Authors.

The management of enteroatmospheric fistula (EAF) in open abdomen (OA) therapy is challenging and associated with a high mortality rate. The introduction of negative pressure wound therapy (NPWT) in open abdomen management significantly improved the healing process and increased spontaneous fistula closure. Retrospectively, we analysed 16 patients with a total of 31 enteroatmospheric fistulas in open abdomen management who were treated using NPWT in four referral centres between 2004 and 2014. EAFs were diagnosed based on clinical examination and confirmed with imaging studies and classified into low (<200 ml/day), moderate (200-500 ml/day) and high (>500 ml/day) output fistulas. The study group consisted of five women and 11 men with the mean age of 526 years [standard deviation (SD) 119]. Since open abdomen management was implemented, the mean number of re-surgeries was 37 (SD 22). There were 24 EAFs located in the small bowel, while four were located in the colon. In three patients, EAF occurred at the anastomotic site. Thirteen fistulas were classified as low output (419%), two as moderate (65%) and 16 as high output fistulas (516%). The overall closure rate was 613%, with a mean time of 467 days (SD 434). In the remaining patients in whom fistula closure was not achieved (n = 12), a protruding mucosa was present. Analysing the cycle of negative pressure therapy, we surprisingly found that the spontaneous closure rate was 70% (7 of 10 EAFs) using intermittent setting of negative pressure, whereas in the group of patients treated with continuous pressure, 57% of EAFs closed spontaneously (12 of 21 EAFs). The mean number of NPWT dressing was 9 (SD 33; range 4-16). In two patients, we observed new fistulas that appeared during NPWT. Three patients died during therapy as a result of multi-organ failure. NPWT is a safe and efficient method characterised by a high spontaneous closure rate. However, in patients with mucosal protrusion of the EAFs, spontaneous closure appears to be impossible to achieve.

A new technique for intra-operative breast cancer tissue recognition is proposed. Using the open-ended probe covered by Mylar® film we investigated dielectric properties of breast tissue samples coming from 131 patients. The high efficiency in differentiation between normal and anomalous tissue and the ability to fulfil aseptic conditions is promising in cancer diagnostics. Presence of blood and electrolytes does not disturb measurements. A prototype of intra-operative cancer probe was designed and tested. © 2010.

Background & Aims The aim of the study was to evaluate early metabolic perfusion, and microstructural cerebral changes in patients with the hepatitis C virus (HCV) infection and normal appearing brain on plain MR using advanced MR techniques, as well as to assess correlations of MR measurements with the liver histology activity index (HAI). Methods Fifteen HCV-positive patients and 18 control subjects underwent single voxel MR spectroscopy (MRS), perfusion weighted imaging (PWI), and diffusion tensor imaging (DTI), using a 1.5T MR unit. MRS metabolite ratios (NAA/Cr, Cho/Cr, mI/Cr) were calculated. PWI values of relative cerebral blood volume (rCBV) were assessed from 8 areas including several cortical locations, basal ganglia, and fronto-parietal white matter. DTI fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values were obtained from 14 white matter tracts. Results Compared to controls, HCV-positive patients showed significantly (p <0.05) lower NAA/Cr ratios within frontal and parietal white matters, lower rCBV values within frontal and temporo-parietal cortices, decreased FA values, as well as increased ADC values in several white matter tracts. We also found elevated rCBV values in basal ganglia regions. The increase in mI/Cr and Cho/Cr ratio was correlated with a higher HAI score. Conclusions The results of advanced MR techniques indicate neurotoxicity of HCV reflected by neuronal impairment within white matter, cortical hypoperfusion, and disintegrity within several white matter tracts. Hyperperfusion in basal ganglia may be an indicator of brain inflammation in HCV patients. Our findings may suggest a biologic link between HCV-related liver disease and cerebral dysfunction.

The binding of piroxicam (PIR) to human (HSA), bovine (BSA) and sheep (SSA) serum albumin in native and destabilized/denaturated state was studied by the fluorescence quenching technique. Quenching of the intrinsic fluorescence of three analyzed serum albumins was observed due to selective exciting of tryptophanyl and tyrosil residues at 295 nm and 280 nm. Based on fluorescence emission spectra the quenching (KQ) and binding constants (K a) were determined. The results showed that PIR is bound mainly in IIA subdomain of HSA and is additionally able to interact with tyrosil groups located in subdomains IB, IIB or IIIA. PIR interacts only with tryptophanyl residues of BSA and SSA [Trp-214, Trp-237 (IIA) and Trp-135, Trp-158 (IB)]. The presence of denaturating factors modified the mechanism of fluorescence quenching of SSA by PIR. Linear Scatchard plots suggest that HSA, BSA and SSA bind PIR in one class of binding sites. © 2012 Elsevier B.V. All rights reserved.

The aim of the study was to "refresh" the knowledge about the course of acute appendicitis, to confront the classical clinical picture with the practice, analyze its fluctuations and identify factors influencing these. Material and methods. All patients admitted to the Department of General Surgery in Grudzia̧dz District Hospital with the suspicion of acute appendicitis, who underwent appendectomy and in whom the appendicitis was confirmed in pathologic examination were included in the study. There were 85 patients, 49 men (58%) and 36 women (42%) in a mean age of 30 years (range 10-75). Symptoms, signs and results of biochemical tests (leukocyte rate and CRP) were considered in the analysis. Results. The commonest constellation of symptoms and signs, occurring in at least of 3/4 patients consisted of pain and tenderness localized in right lower quadrant (100%), which exacerbates at movements (98%), felling unwell (93%), loss of appetite (88%), and rebound tenderness in right lower quadrant (74%). Conclusions. No particular fluctuation of clinical features in relation to gender, age, duration of symptoms, biochemical parameters and morphological severity of the inflammation was observed. Relevant findings included relatively fast development (<12 hrs) of advanced appendicitis in 18% of adult patients and more than a half patients with normal body temperature, regardless true appendicitis.

We determined the frequency of occurrence and dynamism of the mentioned retrograde lesions. The investigated material comprised 371 cartilages collected from 95 male tracheas (mean age: 56 ±13 years), and 279 cartilages collected from 70 female tracheas (mean age: 65.3 ±14 years) during the process of aging. The dynamism proved non-homogenous with a visible gender difference. The empirical regression curves often crossed each other. Some of the presented curves in female patients were observed beginning two decades after that of male patients, and at lower levels. Thus, it seems hard to conclude that some processes considering tracheal cartilage morphokinesis always precede others.
