Ninety-four patients with occasionally elevated (borderline) blood pressure, 61 patients with asymptomatic established hypertension, and 63 normal subjects have been studied at rest and during a progressive exercise test on a cycle ergometer. Subjects with borderline blood pressure had increased cardiac output in the resting recumbent position, but this was not maintained in the sitting positio...

There may be difficulties in the diagnosis of unilateral endocrine exophthalmos particularly in the differential diagnosis from orbital tumour. It is the purpose of this communication to show that endocrine ophthalmopathy is always bilateral, although its exophthalmic component is frequently unilateral in its early stages. This observation could be the basis of differential diagnosis between "u...

OBJECTIVE To determine the effect of upper limb effort on maximal lower limb muscle activation in individuals with incomplete spinal cord injury. METHODS Fifteen individuals with incomplete spinal cord injury performed recumbent stepping using different combinations of upper and lower limb efforts. RESULTS There was no significant difference in active lower limb electromyography amplitudes ...

The ingestion of isotonic saline solution, long considered to have little or no immediate effect on urine flow (1), has recently been shown by Blomhert (2) to be followed by brisk water diuresis. Further, several investigators have demonstrated that similar diuresis may result from intravenous infusion of isotonic saline solution (2, 3, 4). Examination of the latter experiments reveals at least...

The primary aim of the INTERGROWTH-21(st) Project is to construct new, prescriptive standards describing optimal fetal and preterm postnatal growth. The anthropometric measurements include the head circumference, recumbent length and weight of the infants, and the stature and weight of the parents. In such a large, international, multicentre project, it is critical that all study sites follow s...

It is well established that renal acid excretion can be influenced by certain tubular mechanisms that operate independently of systemic acid-base equilibrium. Thus, the stimulus for sodium reabsorption (1, 2), the competition between potassium and hydrogen ions for secretion (3), and the penetrating ability of anions present in the glomerular filtrate (4-6) are factors known to affect acid excr...

413 T SYNDROMES associated with edema in the absence of renal, cardiac, hepatic, pulmonary, central nervous system, or vascular disease have been described in mature women: Streeten and Conn in 1951’ reported edema of obscure origin in six women who demonstrated excessive daily weight gain, reversal of normal diurnal variation of water excretion, and inability to excrete a water load normally w...

The hormonal regulation of sodium and volume homeostasis was investigated in three patients (two related) with the syndrome of familial hyperkalemic acidosis and hypertension with normal glomerular filtration rate. Recumbent plasma renin activity was low during normal sodium intake (135 mmol daily), and the response to upright posture or to low sodium diet (10 mmol daily) was blunted. Recumbent...
