<p>Shock Waves as a Treatment Modality for Spasticity Reduction and Recovery Improvement in Post-Stroke Adults – Current Evidence and Qualitati…
2020
Purpose: This systematic review examines intervention studies using extracorporeal shock wave therapy (ESWT) application in post-stroke muscle spasticity with particular emphasis on the comparison of two different types of radial (rESWT) and focused shock waves (fESWT). Methods: PubMed, PEDro, Scopus, and EBSCOhost databases were systematically searched. Studies published between the years 2000 and 2019 in the impact factor journals and available in the English full-text version were eligible for inclusion. All qualified articles were classified in terms of their scientific reliability and methodological quality using the PEDro criteria. The PRISMA guidelines were followed and the registrat…
The electrocardiographic ‘triangular QRS-ST-T waveform’ pattern : a marker of severe haemodynamic compromise in Takotsubo syndrome : a case report
2020
Abstract Background Takotsubo cardiomyopathy is characterized by transient regional systolic dysfunction of the left ventricle, mimicking myocardial infarction. Although systolic left ventricular (LV) function normalizes in most cases, the outcome is not always favourable. Recently, a rare electrocardiogram (ECG) finding, lambda wave ST elevation or ‘triangular QRS-ST-T waveform’, was suggested as a possible marker of poor outcome in Takotsubo patients Case summary After a brief episode of chest pain and shortness of breath, a 67-year-old woman developed cardiogenic shock. Her resting ECG showed widespread ST elevations, which soon evolved into a pattern of triangular QRS-ST-T waveforms in …
Endothelial function, adipokine serum levels and white matter hyperintesities in subjects with diabetic foot syndrome.
2019
Abstract Context No study has analyzed the prevalence of white matter hyperintensities (WMHs) in subjects with diabetic foot syndrome (DFS) and their relationship to adipokine serum levels and indexes of endothelial and cognitive performance. Objective To evaluate omentin and vaspin serum levels and the prevalence of WMHs in subjects with DFS and to analyze their relationship with other endothelial, arterial stiffness, and cognitive functions. Design Case-control study enrolling 40 subjects with DFS, 40 diabetic subjects without foot complications, 40 controls with foot lesions without diabetes, and 40 patients without diabetes mellitus. Main Outcome Measures Pulse wave velocity (PWV), augm…
An irregular atrial tachycardia : What is the underlying mechanism?
2017
A particular bigeminy during atrial tachycardia.
2014
The ECG shows clearly visible P waves only in lead V1 (Fig. 1). Regular PP intervals and an isoelectric baseline are present between the P waves, so the diagnosis is atrial tachycardia [1]. During the ECG recording, lead V1 shows 12 P waves but some of these are not visible because they are concealed by the QRS complex (Fig. 2). In lead V1, the beats following the long RR intervals are conducted by the first and the seventh P wave and the premature QRS complexes are conducted by the third and the ninth P wave because the fourth and the tenth P wave are too close to the following QRS complex to conduct the impulse. Consequently, the atrial tachycardia presents an alternating 2:1 and 4:1 cond…
An uncommon clinical picture: Wellens’ syndrome in a morbidly obese young man
2010
A 39-year-old man presented to the emergency department (ED) of the ‘‘Paolo Giaccone’’ Academic Hospital, Palermo (Italy). He had anterior chest pain that did not radiate to the neck or arms. The patient came from home where the chest pain initiated. The patient was morbidly obese (BMI 54 kg/m). At the ED, the patient’s blood pressure was 120/80 mmHg, the serum troponin I concentration was 0.029 ng/ml (normal values \ 0.034, borderline 0.034–0.12), myoglobin 45 ng/ml (normal values \ 120). While experiencing chest pain, the patient underwent a standard 12 lead electrocardiogram (ECG) that was normal. An echocardiogram, also during the chest pain, excluded the presence of hypo-akinetic left …
Inflammation and Aortic Stiffness: An Individual Participant Data Meta‐Analysis in Patients With Inflammatory Bowel Disease
2017
Background The recent finding that aortic pulse wave velocity ( aPWV ) is increased in patients with inflammatory bowel disease may explain why the cardiovascular risk is increased despite the low prevalence of traditional cardiovascular risk factors. We aimed to test whether inflammation is associated with aortic stiffening in this setting after adjustment for major confounders and to perform subgroup analyses. Methods and Results A systematic literature search for aPWV in inflammatory bowel disease was performed using PubMed, Scopus, Web of Science, and Google Scholar databases (last accessed May 7, 2017). Inclusion criterion was peer‐reviewed publications on clinical studies reporting o…
Analysis of radiolucent gallstones by computed tomography for in vivo estimation of stone components.
1990
. Successful oral litholytic and other non-operative therapies of gallstones require exact determination of the stone components. Since computed tomography (CT) provides highly sensitive measurement of density, we performed a study to evaluate whether CT measurement of stone density allows a prediction of the composition of radiolucent gallstones. Twenty-eight patients presenting with 29 radiolucent gallbladder (n= 17) or common bile duct stones (n=12) were included. Prior to operative or endo-scopic therapy the attenuation values (Hounsfield Units, HU) were assessed in vivo by CT under standardized conditions (Somatom II, 125 KV, 130 mAs). After surgical or endoscopic stone removal the con…
Treatment of paediatric urolithiasis by extracorporeal shock-wave lithotripsy.
1988
Non-surgical removal of renal and ureteral stones has proven successful in adults. In this study, 21 paediatric patients have been treated with the first generation extracorporeal shock-wave lithotriptor and an additional 13 children with a second generation local shock-wave lithotriptor. A total of 47 stones was treated. Treatment-related complications such as colics (17%/18.8%) or fever (8.3%/6.2%) were minimal. Stone passage occurred in 93% and 100%, respectively of each group. Open surgery is still the treatment of choice for large staghorn calculi. Extracorporeal shock-wave lithotripsy can be performed successfully in paediatric nephrolithiasis with stones of limited size.
