Takotsubo cardiomyopathy (TTC) consists of an acute onset of transient akinesia of various parts of the left ventricle (apex and mid in classical TTC, mid and base in the variant form), without significant coronary artery stenosis, often accompanied by chest pain, dynamic reversible ST-T segment abnormalities and elevation of cardiac enzymes disproportionate to the extent of akinesia. Contrast-...

Introduction: Due to severe burden of depressive disorders and a low rate remission in patients receiving antidepressant therapy, there is an urgent need for developing novel agents with action fundamentally new mechanism action. 3-ethoxythietane-1,1-dioxide (N-199/1) molecule that showed significant properties when administered intraperitoneally once or repeatedly. The aim the present study wa...

Akinesia and gait disturbances are particularly incapacitating for patients with Parkinson's disease. The anatomical and physiological substrates for these disturbances are poorly understood. The pedunculopontine nucleus (PPN) is thought to be involved in the initiation and modulation of gait and other stereotyped movements, because electrical stimulation and the application of neuroactive subs...

AIMS The microvasculature damage after myocardial infarction has important implications. The hypothesis of the study was that wall motion abnormalities and microcirculation status do not necessarily match after myocardial infarction, and therefore the study of only myocardial wall motion could offer an incomplete evaluation in these patients. METHODS Wall motion and myocardial perfusion asses...

Akinesia (or absence of movement) is a prominent feature of Parkinson's disease. Akinetic symptoms, however, are also observed in depression and schizophrenia, which support the hypothesis that akinesia involves more than only motor behavior. A common feature of these disorders is the disruption of dopamine homeostasis in the CNS. Here we aimed at relating the respective involvement of the nigr...

AIMS Detection and correct localization of transmural lesions can be important for optimal treatment of patients with chronic coronary artery disease (CAD). The aim of the study was to investigate the ability of peak longitudinal ejection strain (PLS) to detect the presence and extent of scar-tissue in CAD patients with normal or near normal ejection fraction, in comparison to cardiac magnetic ...

Fetal akinesia refers to a broad spectrum of disorders in which the unifying feature is a reduction or lack of fetal movement. Fetal akinesias may be caused by defects at any point along the motor system pathway including the central and peripheral nervous system, the neuromuscular junction and the muscle, as well as by restrictive dermopathy or external restriction of the fetus in utero. The f...

BACKGROUND Volumes of local anaesthetics for sub-Tenon's anaesthesia vary. Lower volumes produce less akinesia, whereas higher volumes increase chemosis and intra-ocular pressures. Hyaluronidase is often added to local anaesthetics to improve akinesia without increasing the volume of the injection, but this is controversial. This randomized, sequential allocation study examines the addition of ...

OBJECTIVE To compare the efficacy of subtenon with peribulbar local anesthesia without hyaluronidase in patients undergoing cataract surgery. STUDY DESIGN A randomized controlled trial. PLACE AND DURATION OF STUDY Eye "B" Unit, Khyber Teaching Hospital, Peshawar, from October 2009 to October 2010. METHODOLOGY Patients undergoing cataract surgery were divided into two groups. Group A recei...

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...
