Eva Korcakova, Hynek Mirka, Vaclav Liska, Petr Hosek, Kristyna Bajcurova
AIM: Our research evaluated the ability of contrast-enhanced ultrasound (CEUS) and contrast enhanced computer tomography (CECT), performed 48 h after radiofrequency ablation (RFA), to detect residual tumor tissue. As recently published studies have evaluated periprocedural CEUS performed within 24 h after procedure and their results were not satisfactory, it seems that postponing the control test by one day could increase the sensitivity of both methods. PATIENTS AND METHODS: We evaluated 33 patients with 37 lesions, who met the criteria for our study...

BK virus nephropathy (BKVN) is a serious opportunistic infection threatening renal function especially during the first year after transplantation. Its incidence is now on the rise and is closely related to the level of the recipient's immune system inhibition. This is more intensive with current trends in transplantation medicine, where more potent immunosuppressive protocols are used and more aggressive antirejection therapy is applied. In the absence of BK virus (BKV) specific therapy and limited treatment options for advanced BKVN, active screening of BKV replication and subsequent preemptive adjustment of immunosuppression are essential measures to prevent BKVN...

Obesity and insulin resistance are closely associated with chronic inflammation in adipose tissue, where macrophages play an important role. Adipose tissue macrophages can be divided into two main phenotypes: the classical M1 macrophages and alternatively activated macrophages M2. M1 macrophages produce pro-inflammatory cytokines (TNF-α, interleukin IL-6 and MCP-1) and thus contribute to the development of insulin resistance. On the other hand, M2 macrophages, anti-inflammatory, are involved in the maintenance of tissue homeostasis and are typical in the adipose tissue of slender individuals...

BACKGROUND: Cytomegalovirus enterocolitis is a rare but potentially life threatening complication after allogeneic stem cell transplantation. Its early diagnosis and treatment are essential for a successful outcome. OBJECTIVE: To determine the potential benefit of fecal CMV DNA detection in the diagnosis of CMV colitis among stem cell transplant recipients. STUDY DESIGN: Biopsies from the lower gastrointestinal tract, taken during 69 episodes of diarrhea, were compared with fecal samples previously examined for CMV DNA in 45 patients after allogeneic stem cell transplantation...

BACKGROUND: The standard treatment for metastatic renal cancer is based on vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTor) inhibitors. Compared to other advanced tumors, the treatment of renal cancer is highly affected by impaired renal function; therefore, patients with severe renal insufficiency, including patients on hemodialysis, are generally excluded from clinical trials. CASE REPORT: In the present manuscript we present the case of a renal cancer patient who underwent bilateral nephrectomy and received two lines of treatment...

Triple negative breast cancer (TNBC) is an aggressive form of breast cancer (BC) with a poor prognosis. Second, patients cannot benefit from targeted therapy, except for those with BRCA1/2 mutations, for whom poly (ADP-ribose) polymerase (PARP) inhibition therapy using olaparib has recently been approved. As global priorities continue to be epidemiological analysis of BC risk factors and early diagnosis, this review focuses on the risks and protective factors associated with TNBC. A PubMed keyword search for new knowledge on the risks and protective factors for TNBC was carried out...

Patients who are unable to receive oral medication (p.o.) are a major problem in outpatient settings, especially in home health care systems. Mucosal administration of drugs offers an alternative to the oral route, especially when the parenteral mode cannot be used. There are three main pathways of mucosal administration: sublingual/buccal, intranasal and rectal. We discuss the possibility of mucosal delivery of antihypertensive drugs. Perindopril arginine and Amlodipine besylate are registered in the EU as orodispersible tablets for oromucosal delivery, however, they are not available in all countries...

OBJECTIVE: Mesiodens is the most common form of supernumerary tooth mainly located between the maxillary central incisors. Its etiology is not completely understood but both genetic and environmental factors are assumed. The degree of mineralization and inorganic element content in hard tooth tissues is poorly understood as well as is the durability and suitability for allo- and auto-transplantation. Therefore aim of this study was to examine the content of inorganic elements. MATERIALS AND METHODS: This study included 26 mesiodens teeth and 26 normal central incisor teeth as controls...

The correct diagnosis of CPA tumours is a relatively common issue in both neurological and ENT practice, the omission of which can have serious consequences for the patient. Properly set clinical guidelines and diagnostic protocols are key aspects of good clinical practice. In the case of CPA tumours, two options are available: the first is diagnosis with the help of an ABR as the primary tool for determining the group of patients with a possible tumour; the second is an MRI scan of the posterior cranial fossa...

BACKGROUND: Epigenetic modifications have been recognized as an important mechanism underlying carcinoma progression. DNA methylation plays an important role in cancer biology and represents potentially heritable changes in gene expression that do not involve DNA sequence. The aim of this study was to investigate promoter methylation of selected genes in sinonasal carcinoma by comparison with noncancerous sinonasal tissue. METHODS: To search for epigenetic events (methylation in 25 tumor suppressor genes) we used MS-MLPA (Methylation-specific multiplex ligation-dependent probe amplification) to compare methylation status of 59 formalin fixed, paraffin embedded tissue samples of sinonasal carcinomas with 18 control samples...

INTRODUCTION: Hysteroscopy with biopsy is a common diagnostic and therapeutic method in gynaecology. Its use is preceded by ultrasound examination. The success rate of predicting intrauterine findings based on ultrasound has not been assessed in the Czech Republic for a long time. In the meantime, there have been technological improvements in ultrasound devices. METHOD: Patients indicated for hysteroscopy underwent ultrasound examination and their medical history was recorded...

BACKGROUND: Clinical monitoring is the most common method of adjusting the appropriate level of general anesthesia. However, episodes of intraoperative awareness (AWR) are still reported, suggesting that clinical observations may not be sufficient in some cases. The objective of this study was to compare the efficacy of clinical and instrumental neuromonitoring with auditory evoked potentials (AEP) in an intraoperative analysis of the proper level of general anesthesia. METHODS: Patients scheduled for elective surgery were randomly divided into two groups...

BACKGROUND: Leri-Weill syndrome (LWS) ranks among conditions with short stature homeobox gene (SHOX) haploinsufficiency. Data on possible association of SHOX aberrations with malignant diseases are scarce. METHODS AND RESULTS: We report a unique case of an 8-year-old girl who was successfully treated for acute lymphoblastic leukemia (pre-B ALL, intermediate risk) and was subsequently diagnosed with LWS due to characteristic clinical appearance (short disproportionate stature, Madelung deformity of the wrist) and molecular genetic examination (complete deletion of SHOX)...

Atherosclerosis is the most common cause of both carotid and coronary steno-occlusive disease. Rupture of an atherosclerotic plaque may lead to the formation of an overlying thrombosis resulting in complete arterial occlusion or downstream embolism. Clinically, this may manifest as a stroke or acute myocardial infarction, the overall leading causes of mortality and disability in developed countries. In this article, we summarize current concepts of the development of vulnerable plaque and provide an overview of commonly used imaging methods that may suggest/indicate atherosclerotic plaque vulnerability...
