T M, man aged 48 History: Admitted in 1956 with an episode of swelling of legs and backache following a 'cold'. Since then, the patient has been periodically admitted with recurrent attacks of leg cedema, which respond promptly to bed rest. He has been unable to work since 1969, as he found it too uncomfortable to continue standing after 4.00 pm and required two days of bed rest a week to control the swelling. On examination: (September 1973) The patient was obese, with ankle and leg aedema. Blood pressure (readings taken on a tilt table): 125/80 (recumbent), 120/100 (standing). Investigations: ECG and Chest X-ray - normal. Total proteins - 8.3 g/100 ml. Serum albumin 4.85 g/100 ml. Blood urea - 43 mg/100 ml. Na 142, K - 4.3 mmol/l; 24-hour urinary protein 280 mg. Lymphangiogram and venogram (1969) normal. Creatine clearance - 123 mI/min (recumbent), 21.1 ml/min (standing). Water load test (1500 ml) - recumbent: 1500 ml excreted within 4 hours. Standing: 250 ml excreted within 4 hours. After a and P blockade, standing: 1050 ml excreted. Urinary metanephrines - 347 ,g/24 hours. Plasma renin: 2.84 ,tg/h/ml (recumbent), 4.73 ,g/h/ml (standing 4 hours later, on 100 mEq Na diet); both results within the normal range. Aldosterone: 3 ng/100 ml (recumbent), 11.0 ng/100 ml (standing 4 hours later, on 100 mEq Na diet); both results within the normal range. Capillary filtration ccefficient - 0.02 ml per min per mmHg per 100 ml tissue (normal). IVP and renal angiogram showed the left kidney to drop considerably when the patient was tilted to the upright position.

Comment The syndrome of periodic cedema is well known in women. The mechanism is not understood, though abnormalities in albumin metabolism (Gill, Waldmann & Bartter 1972), aldosterone (Hill et al. 1960) and an increase in adrenergic activity (Gill, Cox, Delea & Bartter 1972) have been recorded. The syndrome in males has not, to my knowledge, been documented. The results of treatment by a and 8 blockade suggest that adrenergic activity, perhaps through the renin angiotensin system, is involved. It is postulated that the postural mechanism may be related to the position change of the left kidney. Acknowledgments: I am grateful to Dr J D H Slater (Middlesex Hospital) for the renin measure-

Professor J R Hobbs said that as one who had participated in the original studies of the effect of posture on renal clearances, he could assure them that none of their subjects ever showed such a dramatic reduction in creatinine clearance. Since the rest of this patient's syndrome and findings could all be explained by that reduction, he would encourage them to see if a good surgeon could improve the blood flow through the patient's kidney(s) when in a vertical position. With forethought, this might even be checked during the operation. Mr A P Wyatt said that a radioactive renogram might give further information about the suspected dramatic change in renal blood flow with variation in posture if it could be performed with the patient lying down and then standing. He was doubtful that a nephropexy would cure the complaint because although there was undoubted change in position of the kidney with posture there was no obvious kinking or other obstruction to the renal artery. It was not certain that the movement of the kidney that had been demonstrated with posture was outside the expected normal range.
