In patients with orthostatic intolerance, the mechanisms to maintain BP (blood pressure) fail. A physical counter-manoeuvre to postpone or even prevent orthostatic intolerance in these patients is leg crossing combined with muscle tensing. Although the central haemodynamic effects of physical counter-manoeuvres are well documented, not much is known about the peripheral haemodynamic events. The...

The objective of the present study was to evaluate the influence of posture on the responses of blood pressure (BP) and heart rate (HR) to the Valsalva manoeuvre (VM). Neurohumoral activation, as well as changes in intravascular and intracardiac volumes and pressures, are well known effects of orthostatic stress. These changes are likely to have significant effects on cardiovascular reflexes, s...

BACKGROUND Shifting dullness and fluid wave are two techniques commonly used to detect ascites. However, these may fail to detect moderate or minimal ascites. Ultrasonography is a good non-invasive method to detect ascites but may not be available in distant rural areas of India. We assessed the utility of the puddle sign and auscultatory percussion for detecting ascites. METHODS Sixty-six pa...

OBJECTIVES To clarify the clinical significance of positional down beat nystagmus (pDBN). METHODS A discussion of the neuro-otological findings in 50 consecutive patients with pDBN. RESULTS In 38 patients there was evidence of CNS disease (central group) but in 12 there was not (idiopathic group). In the CNS group, presenting symptoms were gait, speech, and autonomic dysfunction whereas in ...

Background: Benign paroxysmal positional vertigo (BPPV) is a common problem encountered in medical and otorhinolaryngological practice. It is quite a distressing symptom and affects the patients day-to-day activities. A multifactorial etiology has been attributed to the symptom of vertigo. Causes may be otological, neurological, medical or psychogenic. BPPV is probably the most common cause of ...

the same time (two players of the attacking team, the last two players of the defending team, and the ball), and this may not be compatible with the normal eye function—especially as these five objects can be anywhere within the defenders’ half of the pitch, an area of at least 3200 m. This may explain at least some of the instances when television replays of a game clearly show that the offsid...

INTRODUCTION Benign paroxysmal positional vertigo (BPPV) is one of the most common conditions that cause the physiognomy of peripheral vertigo. OBJECTIVE To evaluate the effectiveness of Epley's manoeuvre (EM) in the treatment of BPPV using a critical review of the medical literature and a meta-analysis. METHODS Searches were made in the databases of MEDLINE (PubMed), in the Cochrane collec...
