21. Influence of surgical treatment and radiotherapy of the advanced intraoral cancers on complete blood count, body mass index, liver enzymes and leukocyte CD64 expressionTadej Dovšak, Alojz Ihan, Vojislav Didanovič, Andrej Kansky, Nataša Ihan Hren, 2009, original scientific article Abstract: Background. The aim of our study was to evaluate the influence of the surgery and radiotherapy of the advanced oral squamous cell carcinoma on the complete blood count, body mass index (BMI), acute inflam-matory response, liver enzymes and expression of the CD64 index on leukocytes in the peripheral blood. Patients and method. Venous blood was obtained from 16 patients with advanced oral squamous cell carcinomas treated with radical surgery and external beam radiotherapy. Blood samples were collected prior to surgery (T1), after surgery (T2) and after radiotherapy (T3). Blood samples were analyzed for whole blood count, immunoglobulin G levels, liver enzymes (transaminases (ALT and AST) and gammaglutamyl trasferase (?-GT)), inflammatory response markers (C-reactive protein, erythrocyte sedimentation rate, albumin, white blood count, leukocyte count and CD64 expression on leukocytes). Assessment of nutrition was done by calculating the body mass index.Results. Surgery caused anaemia, trombocytosis, leukocytosis, lymphopenia, rise in acute phase proteins, elevation of CD64 expression on monocytes and neutrophyls, elevation of liver transaminases and lowering of ?-GT, albumin, protein and bilirubin levels. After radiotherapy haemoglobin, leukocytes, C-reactive protein, erythrocyte sedimentation rate, liver transferases, albumin, bilirubin and proteins returned almost to T1 levels, levels of lymphocytes, ?-GT and body mass index lowered. IgG levels remained almost unchanged at T2 and T3. Levels of the CD64 expression on monocytes and neutrophyls also elevated after radiotherapy.Conclusions. Surgery caused a significantly larger acute phase response than radiotherapy, while radiotherapy worsened the already present lymphopenia.

24. Surgical treatment of malignant pleural mesotheliomaJanez Eržen, Stanko Vidmar, Mihael Sok, Andrej Debeljak, Peter Kecelj, Viljem Kovač, Marjeta Stanovnik, Tomaž Rott, Izidor Kern, 2005, original scientific article Abstract: Background. The aim of the study was to identify perioperative morbidity and mortality, the category and mode of adjuvant treatment, local recurrence and survival in patients treated by extrapleural pneumonectony (EPP) for malignantpleural mesothelioma (NLPM). Methods. From 2000 to 2003, 18 patients with MPM were referred to the Department of Thoracic Surgery in Ljubljana, and17 of them were operated on. Two patients underwent explorative thoracotomy, and 15 patients were evaluated. Five female and nine male patients (aged 52-68 years) were treated by EPP and one male patient by pleurectomy. Eight patients received both adjuvant chemotherapy (ChT) and radiotherapy (RT), with cisplatin 100 mg/m2 + mitomycin C 6-10 mg/m2 gemcitabine 1000 mg/m2 and external beam radiation with 24 Gy - 58 Gy respectively, three patients received no adjuvant therapy, three patients weretreated by adjuvant ChT, two of them were given cisplatin 100 mg/m2 + mitomycin C 6-10 mg/m2, and one patient cisplatin 100 mg/m2 on the first day and gemcitabine 250 mg/rn2 in prolonged 6 hours infusion on the first and on the eighth day. One patient was treated only by adjuvant RT. Results. There were no perioperative deaths and the postoperative morbidity was 42%. Of the 15 evaluable patients, and in the median follow up of 40 months (28-64), we noticed nine (60.0%) recurrences, seven local and two abdominal. Eight (53.3%)patients died, all because of the local progress of disease. (Abstract truncated at 2000 characters)

25. Interventional radiological management of complications in renal transplantationPeter Popović, Katarina Šurlan Popović, 2004, review article Abstract: Background. The most frequent radiologically evaluated and treated complications in renal transplantation are perirenal and renal fluid collection and abnormalities of the vasculature and collecting system. Renal and perirenal fluid collection is usually treated successfully with percutaneous drainage. Doppler US, MRA and digital subtraction angiography (DSA) are most important in the evaluation of vascular complications of renal transplantation and management of the endovaseular therapy. Conclusions. Stenosis, the most common vascular complication, occurs in 1% to 12% of transplanted renal arteries and represents a potentially curable cause of hypertension following transplantation and/or renal dysfunction. Treatment with percutaneous transluntinal renal angioplasty (PTRA) or PTRA with stent has been technically successful in 82 to 92% of the cases, and graft salvage rate has ranged from 80-100%. Complications such as arterial and vein thrombosis are uncommon. Intrarenal A/V fistulas and pseudoaneurysms are occasionally seen after biopsy, the treatment reguires superselective embolisation. Urologic complications are relatively uncommon; they consist predominantly of the urinary leaks and urethral obstruction. Interventional treatment consists of percutaneous nephrostomy, balloon dilation, insertion ofthe double J stents, metallic stent placement and external drainage of the extrarenal collections. The aim of the paper is to review the role of interventional radiology in the management of complications in renal transplantation.

26. Radiologic imaging of acute pancreatitisMojca Glušič, Erika Brenčič, Peter Popović, 2004, professional article Abstract: Background. Acute pancreatitis comprises a broad spectrum of inflammatory changes in the gland and has a variety of causes. The most common are alcoholism and biliary tract disease. This paper discusses the current concepts of diagnosis and the relationship between morphology as depieted by imaging, pancreatic function tests and treatment planning. Conclusions. Our understanding of the morphologic changes produced by the inflammatory process has expanded in the last decade as more sophisticated imaging techniques have been used for evaluation.

27. A web-application that extends functionality of medical device for tumor treatment by means of electrochemotherapyIvan Pavlović, Peter Kramar, Selma Čorović, David Cukjati, Damijan Miklavčič, 2004, original scientific article Abstract: Electrochemotherapy (ECT) is a novel method for efficient tumor treatment in clinical environment. It combines local drug delivery and application of shorthigh voltage pulses, which permeabilize the plasma membrane by electroporation. Drug can enter only the cells with permeabilzed membrane. Recently, medical device CliniporatorTM for controlled electroporation was developed. Here, we present a web-application that extends the functionality of this medical device. The aim of the application is to collect, store and toallow the analysis of every ECT application using this medical device. The application helps transferring data collected by devčce during the electroporation process to the central database, and enables filling of medical records through the web forms. The application is based on technologies ASP, HTML, Flash, JavaScript, XML and others. The application main advantages are easy and rapid data access, scalability and independence of client computer operating system as well as easy application debugging and upgrading.

30. Recovery study of gold nanoparticle markers from lateral flow immunoassaysTilen Švarc, Peter Majerič, Darja Feizpour, Žiga Jelen, Matej Zadravec, Timi Gomboc, Rebeka Rudolf, 2023, original scientific article Abstract: Lateral flow immunoassays (LFIAs) are a simple diagnostic device used to detect targeted analytes. Wasted and unused rapid antigen lateral flow immunoassays represent mass waste that needs to be broken down and recycled into new material components. The aim of this study was to recover gold nanoparticles that are used as markers in lateral flow immunoassays. For this purpose, a dissolution process with aqua regia was utilised, where gold nanoparticles were released from the lateral flow immunoassay conjugate pads. The obtained solution was then concentrated further with gold chloride salt (HAuCl4) so that it could be used for the synthesis of new gold nanoparticles in the process of ultrasonic spray pyrolysis (USP). Various characterisation methods including scanning electron microscopy, transmission electron microscopy, ultraviolet-visible spectroscopy and optical emission spectrometry with inductively coupled plasma were used during this study. The results of this study showed that the recovery of gold nanoparticles from lateral flow immunoassays is possible, and the newly synthesised gold nanoparticles represent the possibility for incorporation into new products.
