Deep learning pipeline for quality filtering of MRSI spectra.

With the rise of novel 3D magnetic resonance spectroscopy imaging (MRSI) acquisition protocols in clinical practice, which are capable of capturing a large number of spectra from a subject's brain, there is a need for an automated preprocessing pipeline that filters out bad-quality spectra and identifies contaminated but salvageable spectra prior to the metabolite quantification step. This work introduces such a pipeline based on an ensemble of deep-learning classifiers. The dataset consists of 36,338 spectra from one healthy subject and five brain tumor patients, acquired with an EPSI variant, which implemented a novel type of spectral editing named SLOtboom-Weng (SLOW) editing on a 7T MR scanner.

icobrain ms 5.1: Combining unsupervised and supervised approaches for improving the detection of multiple sclerosis lesions.

Multiple sclerosis (MS) is a chronic autoimmune, inflammatory neurological disease of the central nervous system. Its diagnosis nowadays commonly includes performing an MRI scan, as it is the most sensitive imaging test for MS. MS plaques are commonly identified from fluid-attenuated inversion recovery (FLAIR) images as hyperintense regions that are highly varying in terms of their shapes, sizes and locations, and are routinely classified in accordance to the McDonald criteria.

Improving the detection of autism spectrum disorder by combining structural and functional MRI information.

Autism Spectrum Disorder (ASD) is a brain disorder that is typically characterized by deficits in social communication and interaction, as well as restrictive and repetitive behaviors and interests. During the last years, there has been an increase in the use of magnetic resonance imaging (MRI) to help in the detection of common patterns in autism subjects versus typical controls for classification purposes. In this work, we propose a method for the classification of ASD patients versus control subjects using both functional and structural MRI information.

Primary malignant fibrous histiocytoma of the spleen: recurrence eight years after splenectomy--report of a case and literature review.

Primary intraabdominal malignant mesenchymal tumors are very rare. There are just few cases of intraabdominal visceral malignant fibrous histiocytoma in the literature. We report a case of primary malignant fibrous histiocytoma of the spleen in a 57-year-old man, with a recurrence eight years after the splenectomy.

Genu recurvatum as a complication after total knee arthroplasty.

A 73-year-old female patient underwent total knee arthroplasty for arthrosis. After surgery, recurvatum instability over 55 degrees occurred. Two years later, primary endoprosthesis was removed and a revision endoprosthesis implanted.

New paradigm in training of undergraduate clinical skills: the NEPTUNE-CS project at the Split University School of Medicine.

Clinical skills' training is arguably the weakest point in medical schools' curriculum. This study briefly describes how we at the Split University School of Medicine cope with this problem. We consider that, over the last decades, a considerable advancement in teaching methodologies, tools, and assessment of students has been made.

Spinal cord stimulation for chronic visceral pain secondary to chronic non-alcoholic pancreatitis.

Spinal cord stimulation (SCS) suppresses visceral response to colon distension in an animal model. In humans, it may be an effective therapy for chronic pain of pelvic origin, irritable bowel syndrome, and persistent unspecified abdominal pain. Described here is the case of SCS for 38-year-old woman with visceral pain secondary to chronic pancreatitis.

Age-related attenuation of isoflurane preconditioning in human atrial cardiomyocytes: roles for mitochondrial respiration and sarcolemmal adenosine triphosphate-sensitive potassium channel activity.

Background: Clinical trials suggest that anesthetic-induced preconditioning (APC) produces cardioprotection in humans, but the mechanisms of APC and significance of aging for APC in humans are not well understood. Here, the impact of age on the role of two major effectors of APC, mitochondria and sarcolemmal adenosine triphosphate-sensitive potassium (sarcKATP) channels, in preconditioning of the human atrial myocardium were investigated.

Methods: Right atrial appendages were obtained from adult patients undergoing cardiac surgery and assigned to mid-aged (MA) and old-aged (OA) groups.

Application of novel lossless compression of medical images using prediction and contextual error modeling.

Conduction of tele-3D-computer assisted operations as well as other telemedicine procedures often requires highest possible quality of transmitted medical images and video. Unfortunately, those data types are always associated with high telecommunication and storage costs that sometimes prevent more frequent usage of such procedures. We present a novel algorithm for lossless compression of medical images that is extremely helpful in reducing the telecommunication and storage costs.

Comparison of on-demand vs planned relaparotomy for treatment of severe intra-abdominal infections.

Aim: To compare morbidity and mortality of patients with severe intra-abdominal infections after two types of surgical treatment, on-demand ("wait and see") relaparotomy and modified planned relaparotomy.

Methods: We prospectively analyzed the outcomes of 65 patients with severe peritonitis surgically treated in two Croatian hospitals. In one hospital, 34 patients were treated on-demand, and in another hospital 31 patients were treated by planned relaparotomy.
