Thirty-seven patients were evaluated before cardiac catheterisation by bedside physical examination, including Valsalva manoeuvre, to assess the value of the sphygmomanometrically determined arterial pressure responses during the Valsalva manoeuvre and to compare its sensitivity, specificity, and predictive accuracy in the detection of left ventricular dysfunction with that of the commonly used...

The negative expiratory pressure (NEP) method has been previously used to assess the performance of forced vital capacity (FVC) manoeuvre in normal adults. The aim of the present study is to assess whether flow limitation is achieved during FVC manoeuvres in children aged 6-14 yrs. NEP (-10 cmH2O) was successfully applied in 177 normal children, the portion of FVC over which expiratory flow did...

We describe a modification of Belghiti's liver hanging manoeuvre (LHM) using two small tubes placed in the cut planes, the first between the left lateral and medial sections, and the second along the right hepatic vein, to achieve complete anatomic central hepatectomy for a large tumour compressing surrounding vessels. Using this technique, a large central hepatocellular carcinoma compressing h...

background and aim: although nuchal cord is a common occurrence at birth, there is little attention to its importance or management at birth, and teaching includes premature clamping and cutting of the cord as the common option.  although grade 1 evidence is lacking, the optimal management of the nuchal cord,  the somersault manoeuvre  is not taught or included in any current guidelines. what e...

Current research focuses on designing fast trajectories to the trans-Neptunian object (TNO) (90377) Sedna study surface and composition from a close range. Studying distance can provide unique data about Solar System evolution process including protoplanetary disc related mechanisms. The are determined considering flight time total characteristic velocity (${\Delta}V$) constraints. of for analy...

OBJECTIVE Autonomic nerve dysregulation produces a sense of impaired well-being and interferes with work performance in affected individuals. In this study, we characterized the pathophysiology of this condition. METHODS Six patients with high symptom scores for orthostatic intolerance (OI) along with age- and sex-matched normal volunteers were directed to perform a head-down manoeuvre, and t...

Interactions between the cardiovascular responses to the Valsalva manoeuvre and sustained handgrip were analysed in 5 men with untreated mild hypertension and 4 young normal subjects. Though set at a higher level, there was a normal blood pressure response to the Valsalva manoeuvre during concurrent sustained handgrip in 4 of the 5 hypertensive subjects. At the end of the handgrip period in whi...
