BACKGROUND: Evaluation of acute chest pain in emergency department (ED), using limited resource and time, is still very difficult despite recent development of many diagnostic tools. In this study, we tried to determine the applicability of new semi-automated cardiac function analysis tool, velocity vector imaging (VVI), in the evaluation of the patients with acute chest pain in ED. METHODS: We prospectively enrolled 48 patients, who visited ED with acute chest pain, and store images to analyze VVI from July 2005 to July 2007...

Anomalies of the origin of coronary arteries are detected in 0.5-1.5% of all angiographies. Anomalous origin of the left main trunk is the most uncommon and its origin from pulmonary artery in adults is exceptional, usually because it is associated with a short survival. We report a 49-year-old female, presenting with a two months history of angina. The exercise electrocardiogram suggested ischemia. A coronary angiography was performed, showing the absence of the left main trunk in the left coronary sinus, a dilated right coronary artery, with no lesions and extensive collateral circulation to the anterior descending and circumflex arteries, with inverted flow and the left main trunk draining to the pulmonary artery...

Objectives.: Specific cardiac involvement in granulomatosis with polyangiitis (GPA) is probably underestimated since many of these conditions are subclinical. The objective of this study was to assess the prevalence and patterns of cardiac abnormalities detected by cardiac MRI (CMRI) in patients with GPA. Methods.: Thirty-one consecutive patients with newly diagnosed or relapsing GPA underwent CMRI to assess morphological, functional, perfusion at rest and delayed enhancement abnormalities...

An 18-year-old man came to the hospital because of 1 day of chest pain typical of pericarditis. He had had an upper respiratory infection 10 days earlier. His electrocardiograms indicated evolving pericarditis. His echocardiogram showed mild, diffuse left ventricular hypokinesia, and his troponin I level peaked at 47.5 ng/ml. Thus, he had myopericarditis.

BACKGROUND: Menkes disease (MD) is an X-linked recessive neurodegenerative disorder caused by mutations in ATP7A gene. Depending on the residual ATP7A activity, manifestation may be classical MD, occipital horn syndrome, or distal motor neuropathy. Neurological sparing is expected in female carriers. However, on rare occasions, females may manifest with classical clinical phenotype due to skewed X-chromosome inactivation, X-autosome translocation, and XO genotype. Here, we describe a small series of probands with MD and their response to copper histidine therapy...

Subclavian artery aneurysm is usually operated under general anesthesia (GA), but in specific situations, it can also be conducted under regional anesthesia (RA) such as cervical epidural anesthesia (CEA). A 48-year-old male presented with chief complaint of progressive swelling in the right side of the neck for the past 3 months following trauma. He was diagnosed as subclavian artery aneurysm, and surgical intervention was advised. He had previous history of angina 4 months back for which tablet aspirin 75 mg and tablet clopidogrel 75 mg once daily was prescribed...

INTRODUCTION: Delayed encephalopathy due to carbon monoxide (CO) poisoning can even occur in patients with mild symptoms of acute CO poisoning. Some cases taking conventional hyperbaric oxygen (HBO) therapy or steroid-pulse therapy may be insufficient, and AchEI may be effective. PATIENT CONCERNS AND DIAGNOSES: We report two cases of delayed encephalopathy after acute CO poisoning involving two women aged 69 (Case 1) and 60 years (Case 2) whose cognitive function improved with acetylcholinesterase inhibitor (AchEI) treatment...

BACKGROUND: Gait disorders of Parkinson's disease (PD) are characterized by the breakdown of the temporal organization of stride duration variability that was tightly associated to dynamic instability in PD. Activating the upper body during walking, Nordic Walking (NW) may be used as an external cueing to improve spatiotemporal parameters of gait, such as stride length or gait variability, in PD. The aim of this study was to evaluate the beneficial effects of NW on temporal organization of gait variability and spatiotemporal gait variables in PD...

Subcostal transverse abdominis plane (TAP) block anesthetizes area of the abdomen with cutaneous innervation of T6-T10 dermatomes. These abdominal field blocks become very advantageous when cardiac patient presents for noncardiac surgeries as sole anesthetic or as a part of multimodal anesthesia. A 58-year-male came for open surgical repair of subxiphoid incisional hernia developed post coronary artery bypass grafting (CABG). Echocardiography showed hypokinesia of left ventricle (LV) in the left anterior descending (LAD) artery territory, dilated LV, and ejection fraction of 30%, and coronary angiography after 6 months of CABG showed 70% stenosis of LAD...

Environmental enrichment is a widespread neuroprotective strategy during development and also in the mature nervous system. Several research groups have described that enriched environment in adult rats has an impact on the progression of Parkinson's disease (PD). The aim of our present study was to examine the effects of early, postnatal environmental enrichment after 6-hydroxydopamine-induced (6-OHDA) lesion of the substantia nigra in adulthood. Newborn Wistar rats were divided into control and enriched groups according to their environmental conditions...

PURPOSE: The clinical significance of septic myocardial dysfunction is controversial, a fact that may be explained by the influence of loading conditions. Many indices may be useful to characterize cardiac function during septic shock, but their feasibility and physiological coherence in the clinical setting are unknown. METHODS: Hemodynamic and echocardiographic data with tissue Doppler and speckle tracking were prospectively recorded on the first 3 days of human septic shock...

Akinesia, hypokinesia, and bradykinesia are extensively used to describe motor execution disturbances, but are applied inconsistently and cover more conditions than their Greek translations would suggest. We investigated the origins and changes in meaning of these terms over time, particularly in relation to Parkinson's disease (PD). We searched the literature from 1817 to 2015 for use and interpretation of the words akinesia, bradykinesia, hypokinesia, and PD. We found that akinesia and hypokinesia appeared as terms in the 19th century, opposite to hyperkinesia, but were used in the context of PD since 1920, while at the same time the 'bradykinetic syndrome' was introduced...

Parkinson's disease (PD) patients experience loss of normal motor function (hypokinesia), but can develop uncontrollable movements known as dyskinesia upon treatment with L-DOPA. Poverty or excess of movement in PD has been attributed to overactivity of striatal projection neurons forming either the indirect (iSPNs) or the direct (dSPNs) pathway, respectively. Here, we investigated the two pathways' contribution to different motor features using SPN type-specific chemogenetic stimulation in rodent models of PD (PD mice) and L-DOPA-induced dyskinesia (LID mice)...

BACKGROUND: Typical left bundle branch block (LBBB) during ventricular tachycardia (VT) is a diagnostic criterion of bundle branch reentry tachycardia (BBRT) with activation of the right bundle in the anterograde direction. METHODS AND RESULTS: Eleven patients (seven male, 60 ± 12 years) with nonischemic cardiomyopathy (left ventricular ejection fraction 37 ± 16%) presenting with BBRT were successfully treated by ablation of the right bundle. Among them, five patients had atypical surface electrocardiograms (ECGs) differing from a typical LBBB during the VT...

Huntington's disease (HD) affects both neurons and astrocytes. To target the latter and to ensure brain-wide transgene expression, adeno-associated viral (AAV) vectors can be administered intravenously, as AAV vectors cross the blood-brain barrier (BBB) and enable preferential transduction of astrocytes due to their close association with blood vessels. However, there is a possibility that the subclass of GFAP-expressing astrocytes performs a distinct role in HD and reacts differently to therapeutic measures than the rest of the astrocytes...
