1975). This response strongly suggests that excessive quantities of bile are reaching the colon where they inhibit the ab"sorption of salt, potassium and water, resulting in diarrhoea. Increased fecal concentration of bile acids are reported in patients with postvagotomy diarrhoea (Allan et al. 1973, M South 1975, unpublished) and may therefore be the cause of 'intractable' postvagotomy diarrhoea.

abnormality of an intravenous pyelogram was a duplex kidney with a partial double ureter on the right. Fig 1 illustrates the patient's progress. The KPTT and PT were increased when first measured and remained elevated until the patient was venesected. Three weeks after admission the platelets decreased to 175 000/,ul and the fibrin degradation products (FDP) were found to be increased at 80 ,ug/ml (normal 10 ,ug/ml). At this time, there was no clinical evidence of a deep vein thrombosis or any large thrombosis which might have elevated the FDP. These changes reversed spontaneously before therapy. The patient was treated by venesection of 1700 ml which decreased the h2emoglobin concentration and the h2matocrit. Although venesection was associated with an improvement of coagulation abnormalities, the platelet count remained high; it decreased only after 32p therapy when the coagulation factors remained normal and the hmmatocrit fell further to normal values. Discussion The serious symptoms of polycyth2emia rubra vera are thrombotic (Wetherley-Mein 1974) but

paradoxically it may also present as a bleeding problem. Wasserman & Gilbert (1964) reported that hlemorrhage was the most common complication of surgery in patients with PRV. They also showed in another group of patients with PRV that there was a high incidence of certain coagulation abnormalities in addition to the well-known increase in platelet count, namely an increase in the number of untrapped red cells after clot retraction, a decrease in fibrinogen and an increased prothrombin time. These defects were found in our patient before venesection. The cause for the hemorrhagic diathesis in PRV is not established. It has been suggested that the coagulation defects of PRV may be due to abnormal platelet function but in this patient the coagulation defect was not correlated with the platelet count which increased during venesection while coagulation defects were improving. The combination of abnormalities found in this case, namely the raised FDP, decrease in platelet count and reduction of clotting factors suggest that disseminated intravascular coagulation (DIC) may be a cause of the himorrhagic diathesis. We postulate that hyperviscosity in PRV results in small vessel stagnation and DIC with consumption of clotting factors and platelets. Venesection decreased the hematocrit and resulted in disappearance of the coagulation defects. Such an explanation could resolve the paradox of simultaneous thrombosis and haemorrhage in PRV.

Examination showed thickening and deformity of the 2nd and 3rd metacarpophalangeal joints of the right hand. Investigations: Uric acid 500 ,umol/l, RA latex negative, Hb 15.6 g/dl, ESR 6 mm in 1 hour (Westergren). X-rays of hands showed cystic changes and loss of joint space of 2nd metacarpophalangeal joints of both hands (Fig IA).
