INTRODUCTION: Angiostrongyliasis is a disease caused by Angiostrongylus nematodes that is present worldwide. The infections with the highest impact on human and animal health are caused by A. cantonensis, A. costaricensis, and A. vasorum. Clinical forms of the disease in humans are eosinophilic meningitis and abdominal angiostrongyliasis, while the most common effect on dogs are cardiopulmonary damages. It is deemed as an emerging disease as the result of the global dissemination of the African snail Lissachatina fulica, an intermediary host of these parasites...

BACKGROUND: There is lack of recent multicenter epidemiological data on invasive aspergillosis (IA) among solid organ transplant recipient (SOTr) in the mold-acting antifungal era. We describe the epidemiology and outcomes of IA in a contemporary cohort of SOTr using the Swiss Transplant Cohort Study. METHODS: All consecutive SOTr with proven or probable IA between 01.05.2008 and 31.12.2014 were included. A case-control study to identify IA predictors was performed: 1-case was matched with 3-controls based on SOT type, transplant center, and time post-SOT...

Delusional infestation (DI), also known as delusional parasitosis, consists of a patient's strong belief that he or she is infested with a nonliving substance or living organism despite lack of medical evidence to support this belief. The most commonly reported sources of infestation include insects, fibrous strands, worms, and scabies. Delusional infestation is predominantly seen in women and older patients. This disorder has a variable course and prognosis in patients. Delusional infestation can be a primary psychiatric problem, or secondary to underlying medical conditions or other psychiatric disorders...

Well-differentiated neuroendocrine tumours (NETs) of the digestive tract are being increasingly detected, which is partly explained by the increased use of endoscopic and cross-sectional imaging as well as improved recognition at histopathological evaluation. After the discovery of this relatively indolent type of epithelial malignancy over 100 years ago, their sporadic occurrence and divergent biological behaviour at multiple primary sites have hampered dedicated studies into NET pathogenesis and testing of drug efficacy in well-designed clinical trials...

BACKGROUND: Myocardial scar is associated with adverse cardiac outcomes. The Selvester QRS-score was developed to estimate myocardial scar from the 12-lead ECG, but its manual calculation is difficult. An automatically computed QRS-score would allow identification of patients with myocardial scar and an increased risk of mortality. OBJECTIVES: To assess the diagnostic and prognostic value of the automatically computed QRS-score. METHODS: The diagnostic value of the QRS-score computed automatically from a standard digital 12-lead was prospectively assessed in 2742 patients with suspected myocardial ischemia referred for myocardial perfusion imaging (MPI)...

Introduction: Maturity onset diabetes of the young due to HNF1A mutations (HNF1A-MODY) is the most frequent form of monogenic diabetes in adults. It is often misdiagnosed as type 1 or type 2 diabetes, but establishing genetic diagnosis is important, as treatment differs from the common types of diabetes. HNF1A-MODY has not been investigated in Croatia before due to limited access to genetic testing. In this study we aimed to describe the characteristics of young adults diagnosed with diabetes before the age of 45 years, who have rare HNF1A allele variants, and estimate the prevalence of HNF1A-MODY in Croatia...

Slavica Dodig, Ivana Čepelak
The initial laboratory approach in the diagnosis of allergies is to detect the type of allergic reaction, i.e. whether the patient's allergy is mediated by immunoglobulin E (IgE) or not. For this purpose, the concentration of total serum IgE (tIgE) and specific IgE (sIgE) are determined. Progress in laboratory diagnostics is the use of component-resolved diagnosis (CRD) which implies determination of sIgE against purified native and recombinant allergenic molecules. Component-resolved diagnosis is used in laboratory practice as singleplex and multiplex assays...

Changes in DNA methylation in cancer have been heralded as promising targets for the development of powerful diagnostic, prognostic, and predictive biomarkers. Despite the existence of more than 14,000 scientific publications describing DNA methylation-based biomarkers and their clinical associations in cancer, only 14 of these biomarkers have been translated into a commercially available clinical test. Methodological and experimental obstacles are both major causes of this disparity, but the genomic location of a DNA methylation-based biomarker is an intrinsic and essential property that also has an important and often overlooked role...

It is well known that lower urinary tract symptoms (LUTS) have a multifactorial etiology. Therefore, there is an increased need for improved diagnostics for the optimal assessment of patients with LUTS in order to identify the various causes of symptoms and improve disease phenotyping. Research has focused on the development of improved urodynamic technologies and the development of noninvasive tests that could replace urodynamic studies. This mini-review will present the most recently published studies on the topic including new technologies in the diagnosis of bladder outlet obstruction, novel metrics for bladder sensation, analysis of filling phase rhythm, measurement of detrusor wall tension, and brain imaging during urodynamic studies...

BACKGROUND: Recurrent pregnancy loss (RPL) occurs in 3-5% in about 30% of cases no cause can be found. Women with RPL show higher prevalence of undiagnosed gut disorders. Furthermore, in endometrial tissues of RPL women, higher expression of pro-inflammatory cytokines and Nalp-3 inflammasome has been observed. Aim of this study was to investigate whether an abnormal gut permeability might occur in RPL women and allow passage into systemic circulation of pro-inflammatory molecules able to induce endometrial inflammation...
