Sir, The advances in paediatric cardiology and cardiac surgery have led to earlier and earlier surgical repair of congenital cardiac malformations. In consequence, the clinical picture of many congenital cardiac malformations has changed, and some signs and symptoms are no longer observed in their typical appearance. Sometimes, however, it is possible to recognise the transformation of an old s...

The aim of this study was to investigate the kinematic, kinetic, and electromyographic pattern before, during and after downward squatting when the trunk movement is restricted in the sagittal plane. Eight healthy subjects performed downward squatting at two different positions, semisquatting (40 degrees knee flexion) and half squatting (70 degrees knee flexion). Electromyographic responses of ...

BACKGROUND there long has been debate whether static knee kinematics measured using magnetic resonance imaging are the same as knee kinematics in dynamic weight-bearing motion. Magnetic resonance imaging provides excellent volumetric detail but is static. Fluoroscopic imaging provides for dynamic observation of knee kinematics but provides no direct observation of the soft-tissue structures. We...

IOH (initial orthostatic hypotension) comprises symptoms of cerebral hypoperfusion caused by an abnormally large transient MAP (mean arterial pressure) decrease 5-15 s after arising from a supine, sitting or squatting position. Few treatment options are available. In the present study, we set out to test the hypothesis that LBMT (lower body muscle tensing) attenuates IOH after rising from squat...

BACKGROUND The association between birth position and obstetric anal sphincter injury (OASIS) in spontaneous vaginal deliveries is unclear. METHODS The study was based on the Stockholm-Gotland Obstetric Database (Sweden) from Jan 1(st) 2008 to Oct 22(nd) 2014 and included 113 279 singleton spontaneous vaginal births with no episiotomy. We studied risk of OASIS with respect to the following bi...

abstract background: labor is a physiologic process, and consideration of labor pain and relieving that is among the major components of maternal care. application of some labor position can lay the fetus better in pelvic canal direction. the present study aimed to investigate the effect of laying the mother in three labor positions on the pain severity in the second, third, and fourth stages o...

Aims We assessed changes in pulse pressure (PP) and heart rate (HR) during a squatting test, as indirect markers of arterial stiffness and cardiovascular autonomic neuropathy (CAN), respectively, according to age and gender in patients with type 1 diabetes mellitus. Methods We evaluated 160 diabetic patients, divided in four groups of 20 men/20 women according to age (G1: 20–30 years; G2: 31–40...

PURPOSE To evaluate the preferred position used by Brazilian Urologists to perform DRE, the position that Brazilian patients prefer or think it is less embarrassing to have a DRE, and to evaluate the results of DRE with patients in left lateral decubitus, modified lithotomy, standing-up, or the physician will have them place their elbows on the table and squat down slightly. MATERIALS AND MET...

OBJECTIVE To evaluate pulse pressure changes according to duration of type 1 diabetes and to assess the influence of posture. RESEARCH DESIGN AND METHODS We performed continuous measurement of blood pressure with a Finapres device during a 3 x 1 min posture test (standing, squatting, standing) in 159 type 1 diabetic patients divided into four groups according to diabetes duration (<or=10, 11-...
