Muscle and nerve biopsy may be vital diagnostic tools in various neuromuscular disorders. Since these procedures are invasive, it matters to decide when perform a biopsy, which muscle or selected, how interpret the pathologies. This review addresses indications, methods of biopsies, also significant pathological findings frequently encountered pathology.

BACKGROUND The invasive fractional flow reserve has been considered the gold standard for identifying ischaemia-related stenosis in patients with suspected coronary artery disease. Determining non-invasive FFR based on coronary computed tomographic angiography datasets using computational fluid dynamics tends to be a demanding process. Therefore, the diagnostic performance of a simplified metho...

BACKGROUND Reduction of radiation burden of multidetector computed tomography coronary angiography (CTCA) has remained an important task. OBJECTIVE To compare effective radiation dose of low-dose 64-slice CTCA using prospective ECG-triggering versus diagnostic invasive coronary angiography (CA). METHODS 42 patients referred for elective invasive CA owing to suspected coronary artery disease...

NIFTY (Non-invasive Fetal Trisomy Test) is a non-invasive prenatal test which is used for diagnosing fetal trisomy. The test is based on the analysis of cell free fetal DNA (cffDNA) present in the plasma and serum of a pregnant woman. NIFTY allows to detect fetal trisomy of chromosomes 13, 18, 21, X and Y and also X monosomy. Abnormal NIFTY results still need to be verified using other diagnost...

Objective: This study aimed to establish a new non-invasive diagnostic model for liver fibrosis in Chinese patients with chronic hepatitis B (CHB) and to evaluate its diagnostic accuracy. Methods: This was a prospective study on the liver histology of 240 CHB patients. Patients were divided into 2 groups: 120 patients were included for the establishment of diagnostic model (modeling group) and ...

In many research centers all over the world nowadays works are being carried out aimed at compiling method for diagnosis machines technical condition. Special meaning have non-invasive methods including methods using vibroacoustic phenomena. In this article is proposed using DWT analysis and energy or entropy, which are a base for diagnostic system of fuel injectors damage in car combustion eng...

OBJECTIVE To study short and long term results after surgical closure of isolated ventricular septal defects (VSDs) from 1976 to 1996, especially in relation to changes in preoperative evaluation during this period. DESIGN Retrospective study. SETTING Tertiary referral centre for paediatric cardiac care. PATIENTS All children under 18 years of age who had corrective surgery for VSD betwee...

OBJECTIVE To determine the diagnostic accuracy of echocardiography for indicating surgery without catheterization in patients with congenital heart disease through a prospective analysis and comparison of the echocardiographic diagnosis with the intraoperative findings, or invasive study, or both. METHODS From February 2000 to January 2001, 493 patients with congenital heart diseases indicate...

background: pediatric oncology patients frequently need several painful procedures during their diagnostic and therapeutic process. during the past decades, most centers abroad have developed safe and effective protocols for procedural sedation and analgesia in children. this report describes procedural sedation and analgesia as performed in pediatric oncology unit and tries to report success o...
