INTRODUCTION: The introduction of total mesorectal excision (TME) in the 1980s was pivotal in the surgical treatment for rectal carcinoma (RC). Routinely applied TME led to a significant reduction in the incidence of local recurrences. The purpose of our paper is to present the results of our non-randomized study comparing prospectively acquired data from radical resection / rectal extirpation using classic open access, laparoscopy and da Vinci robotic system. METHOD: The study group included 116 patients with RC who underwent radical surgical treatment between 1/2014-12/2016, after which the collected resection specimens were assessed in pathology laboratories of the referring hospital using the Quirkes protocol...

The purpose of this study was to semi-quantitatively assess the evidence on the value of ultrasound (US) for assessment of haemophilic arthropathy (HA) in children and adults based on the following questions: (1) Does early diagnosis of pathological findings, using available US techniques, impact the functional status of the joint? (2) Do current available US techniques have the ability to accurately detect pathological changes in target joints in haemophilic patients? (3) Does treatment (prophylaxis) improve US evidence of haemophilic arthropathy in children and adults? (4) Is there any association between various US scoring systems and other clinical/radiological constructs? Of the 6880 citations identified searching databases such as MEDLINE, Embase, CENTRAL and Web of Science, 20 articles investigating either the diagnostic accuracy of US and/or US scanning protocols and scoring systems for assessment of HA met the inclusion criteria for the study...

Over the past two decades there have been significant advances in the use of magnetic resonance imaging (MRI) to assess the vascular system. New imaging sequences and improvements in magnet design have enabled the creation of higher spatial resolution images. MRI is now a viable alternative imaging modality when compared to both invasive angiography and computed tomographic angiography. The use of blood pool agents has further facilitated the use of MR angiography (MRA); their high molecular weight allows for lower doses of contrast medium administration while their prolonged presence in the blood stream allows for repeated high-quality volumetric imaging of both the arterial and venous circulation...

Heterotopic Ossification (HO) is a rare but severely debilitating complication after a burn. Despite there being literature of varying quality explaining the postulated pathological process, risk factors and treatment for HO, the individual experiences of adults diagnosed with HO following a burn, remains unreported. This study sought to explore and describe burn survivors' experiences of HO to gain a greater understanding of the clinical needs for this unique patient population. A phenomenological inquiry of five men and one woman selected through purposeful sampling collected in-depth interviews analysed using Colaizzi's method of data analysis...

BACKGROUND: Safe robot-assisted intervention using magnetic resonance imaging (MRI) guidance requires the precise control of assistive devices, and most currently available tools are rarely MRI-compatible. To obtain high precision, it is necessary to characterize and develop existing MRI-safe actuators for use in a high magnetic field (≥3 T). Although an ultrasonic motor (USM) is considered to be an MRI-safe actuator, and can be used in the vicinity of a high field scanner, its presence interferes with MR images...

BACKGROUND: Recent studies of molecular biology have provided great advances for diagnostic molecular pathology. Automated diagnostic systems with computerized scanning for sampled cells in fluids or smears are now widely utilized. Automated analysis of tissue sections is, however, very difficult because they exhibit a complex mixture of overlapping malignant tumor cells, benign host-derived cells, and extracellular materials. Thus, traditional histological diagnosis is still the most powerful method for diagnosis of diseases...
