    Notes: Background: Transjugular intrahepatic portosystemic stent shunts (TIPSS) have been used successfully to reduce portal pressure in the context of variceal haemorrhage. Recent interest has focused on the possible use of TIPSS to manage refractory ascites. Aim: To study the effect of TIPSS insertion in 18 patients with refractory ascites. Results: Response rates were 33.3%, 50%, 33.3% and 26.7% at 1 week, 4 weeks, 3 months and 6 months, respectively. Overall mortality was 50% with a new or worsening encephalopathy rate also of 50%. Patients with lower serum bilirubin and serum creatinine prior to TIPSS insertion had greater response at 1 and 4 weeks, respectively. There was no improvement in either liver or renal function after TIPSS insertion by standard laboratory tests, although serum sodium increased in the responders after 1 month. Conclusion: TIPSS improves refractory ascites in only a minority of patients, and is associated with high encephalopathy and mortality rates.

    Differing actions of the acute administration of propranolol and isosorbide-5-mononitrate on the portal circulation (1996)

    Notes: Background: The aim of this study was to clarify the actions of propranolol and isosorbide-5-mononitrate upon the portal circulation. Methods: Portal haemodynamics were assessed in 16 patients with transjugular intrahepatic portosystemic stent shunts. A reverse thermodilution catheter was positioned in the portal vein, and portal vein pressure and portal vein flow were measured directly. The effects of propranolol 80 mg and isosorbide-5-mononitrate 20 mg over 1 h were determined independently. Results: This demonstrated that propranolol reduced both portal pressure gradient (7.7±2.3 to 5.5±2.1 mmHg, P〈0.01) and portal vein flow (925±123 to 597±99 mL/min, P=0.01) significantly, implying a reduction in splanchnic inflow as its main effect. In contrast, isosorbide-5-mononitrate tended to increase portal vein flow (814±186 to 911±211 mL/min; P=0.06) whilst reducing portal pressure significantly (108±12 to 92±10 mmHg P=0.014). This suggests a fall in intrahepatic resistance and provides no evidence for baroreceptor-mediated reflex splanchnic vasoconstriction. Conclusions: These drugs act upon different variables contributing to portal hypertension and so they may have a powerful synergistic effect in combination. Direct measurement of portal vein flow is a valuable method for assessing the pharmacological modulation of portal venous inflow.

    A comparison of two techniques for inducing fibrous crystallization from solution (1975)

    Notes: Experimental results are presented and discussed comparing two techniques for inducing fibrous growth of polyethylene crystals from flowing solutions: a plunging cone device and a standard rotating cylinder (Couette) device. Comparison of crystal “overgrowth” diameter to spacing ratios for the several experiments with predictions based on an earlier postulated model lead to conclusions regarding the model inadequacy. A detailed comparison is made of the melting behavior of crystals produced by both flow fields and those results are discussed in light of a modified model for the growth process presented elsewhere. The conclusion is reached that differences in melting behavior may be attributed to differences in extension of the high molecular weight chains involved in the growth processes occurring in the two different flow fields.
