Mazen M Kawji, David Luke Glancy
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.

We report a case of 34-year patient who had uncomplicated elective caesarean-section. Postoperatively, she developed sudden hypotension, bradycardia, dyspnea and disseminated intravascular coagulation (DIC), all signs associated with amniotic fluid embolism (AFE). Echocardiogram showed signs of acutely increased right ventricular after load including McConell's sign, i.e. right ventricular dilatation, segmental hypokinesia (mid-right ventricular) and hypercontractile right ventricular apex and overall right ventricular dysfunction...

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...

Current task force criteria (TFC) of cardiac magnetic resonance (CMR) for the diagnosis of arrhythmogenic right ventricular cardiomyopathy (ARVC/D) were generated by comparing probands (mean age of 44 years) to healthy participants of the multi-ethnic study of atherosclerosis (mean age of 60 years). These age differences may be a selection bias because right ventricular end-diastolic volume index decreases 4.6% per decade. Moreover, fat infiltration and late gadolinium enhancement were not included. We evaluated the diagnostic accuracy of TFC using the same methodology used by the task force but comparing probands and age- and gender-matched healthy controls and considering also other morphofunctional and tissue abnormalities detected by CMR...
