A series of 108 arterial embolectomies in 91 patients performed during 1960-64 and 1970-74 is presented. The Fogarty catheter was introduced in our clinic between these periods. Early mortality was 56 and 29%, respectively. Limb salvage rate according to our definition was 38 and 53%, respectively. We found a significantly higher mortality when embolies were located proximal to the profunda femoral artery compared to more distally located embolies. Amputation frequency was 4% after embolectomies performed within 12 hours, but 27% with longer duration of symptoms. Limb salvage rate was significantly higher in patients treated with anticoagulation. In conclusion it is stressed that local surgical therapy should be combined with adequate measures against cardiac failure and other systemic complications. This therapeutic principle is particularly important in cases with proximal embolies.

The significance of fetal arrhythmia presenting during pregnancy and labour has been examined in 68 patients. The different types of rhythm disorders diagnosed included 61 extrasystoles, 6 atrioventricular blocks and 1 auricular fibrillation. Extrasystoles were not associated with acidosis or organic cardiac disease. Atrioventricular block, though not associated with fetal hypoxia, was occasionally associated with congenital cardiac failure.

Eight patients with diuretic-resistant ascites due to cirrhosis were treated by reinfusion of concentrated ascitic fluid. In 11 procedures, with a mean duration of 21.9 hours, weight loss averaged 14.8 kg. Complications during reinfusion included septicemia in 1 procedure, left-sided heart failure in 5, pyrexia in 7 and coagulation abnormalities in 10. Ascites recurred within 2 months after reinfusion in all but one patient. Although this technique is an efficient and inexpensive method of treatment of ascites, it does not appear indicated in patients with cirrhosis and resistant ascites in view of the possibly serious complications associated with reinfusion and the poor long-term results.

A mechanism is outlined to explain why oedema forms so readily in hot climates. A continual cutaneous vasodilation produces a low total peripheral resistance so that the mean arterial pressure cannot be raised except by increasing cardiac output. This inability to raise the arterial pressure as efficiently as usual will lead to difficulties in dealing with excess sodium and water loads, because the mean arterial pressure is the major determinant of urinary output. Anything which favours the retention of sodium and water in hot climates must therefore make things worse. This mechanism will also explain the post-partum cardiac failure syndrome which occurs in Northern Nigeria, since Hausa women take high-sodium diets and lie on heated beds during the post-partum period. The necessity for a further increase of cardiac output to excrete excess sodium and water in hot climates causes stress in persons with vulnerable myocardia and produces the symptoms and signs of cardiac failure more rapidly.

Between 1969 and 1976 sixteen children have had surgery for total atrioventricular canal lesions at the Royal Children's Hospital, Melbourne. Twelve infants had palliative banding of the main pulmonary artery to control heart failure and prevent the development of pulmonary hypertension, with two hospital deaths (17%) and one late death. One other patient has been lost to follow-up and may also have died. Nine patients have undergone complete repair, with three hospital deaths (33%), and one later death at reoperation for residual mitral incompetence. Five of these had previously had banding of the main pulmonary artery, and the mortality has occurred exclusively in this group. The techniques of repair are discussed, and reasons advanced in favour of early primary repair of the defect in preference to palliative banding and later secondary repair.

17 patients with severe hyponatraemia (none had cardiac failure or had lately had an operation) all had excessively high plasma-antidiuretic hormone (A.D.H.). Only 13 had features typical of the syndrome of inappropriate secretion of A.D.H. (S.I.A.D.H.). Plasma-A.D.H. was not related to either plasma-sodium or diagnosis. There were as many patients with chest infection as with carcinoma of the lung. Plasma-sodium and plasma-A.D.H. returned rapidly towards normal in the patients with chest infection or volume depletion but these concentrations corrected much more slowly in patients with carcinoma of the lung. The increase in plasma-sodium in patients with chest infection was too rapid to be produced by water-deprivation treatment and was due to return of plasma-A.D.H. to normal. The term S.I.A.D.H. implies an understanding of pathophysiology that does not exist. As a diagnosis it does not help in management or prognosis. A simpler, more descriptive terminology such as "hyponatraemia with carcinoma of the lung" would be more useful and less confusing in the clinical situation.

The clinical and pathological findings in two brothers with biochemically diagnosed Refsum's disease are given. The pathology, in general, was that already described in this condition. An unusual complication in one case was the development of renal failure. Death was caused in the other by heart failure.

A man, aged 63, had an illness which lasted 11 months from onset with pain under the left costal margin which radiated to the epigastrium, until his death from cardiac failure. His symptoms consisted principally of parasthesias and proximal weakness of both upper and lower extremities with atrophy of the shoulder and pelvic girdles. He developed pyramidal tract signs, became euphoric, emotionally unstable and mentally retarded. There was no clinical evidence of cerebellar dysfunction. Bronchogenic carcinoma was suspected from a tomograph of the thorax, but, in spite of extensive clinical and laboratory studies, the diagnosis was verified only postmortem. The CSF cell count was high at first but diminished as the disease progressed. Muscle biopsies revealed chronic generalized denervation without signs of myopathy. Neuropathologically, encephalomyeloradiculoneuritis concentrated on the spinal cord was combined with severe rarefaction of the ganglion cells of the anterior horns and with bilateral degeneration of the lateral pyramidal spinocerebellar and posterior tracts. A more diffuse process was obvious in the anterolateral tracts of the lumbar region. Polyneuropathy concentrated in the distal region was accompanied by slight inflammatory reaction in the sciatic nerve. Cerebellocortical degeneration which exceeded physiological age-related rarefaction was also present. The findings are discussed in relation to the literature.

9 pre-term babies with patent ductus arteriosus (P.D.A.) and cardiac failure were found to have significantly higher plasma-levels of three prostaglandins (P.G.E, P.G.F, and P.G.FM) than a group of normal pre-term infants of the same age. There was no difference in the plasma-prostaglandin levels before and after surgery in the 5 infants who underwent ligation of the ductus, suggesting that the high P.G. levels are not the result of a patent ductus, but that P.G.S may have a role in the pathogenesis of P.D.A. 3 infants who were treated by indomethacin (a P.G. synthetase inhibitor) showed a sharp initial drop in plasma-levels of the three P.G.S, but levels of P.G.F and P.G.FM had risen either during or within 48 h of completion of the course of indomethacin. These results may explain why high failure-rates have been reported for treatment of P.D.A. by indomethacin.

Propafenone, a new anti-arrhythmia drug, was given at an average dose of 70-140 mg (1-2 mg/kg body-weight) to 124 patients with various types of cardiac arrhythmias. It proved successful in patients with ectopic beats and tachycardias of atrial or ventricular origin. Ectopic beats were suppressed in 40 of 81 patients, while sinus rhythm was restored in 15 of 19 patients with paroxysmal tachycardias. On the other hand, sinus rhythm was restored in only 5 of 22 patients with atrial tachy-arrhythmias, while in most of the others in this group the heart rate decreased markedly during propafenone injection. The effect of propafenone was on atrial and ventricular myocardium and on the conduction system, lowering the discharge rate of sinus node and ectopic pacemakers. ECG signs of pre-excitation disappeared in 4 of 9 patients with WPW syndrome given the drug. Propafenone may prolong atrioventricular and intraventricular conduction, as well as cause a transitory decrease in cardiac function and a fall in systemic arterial blood pressure. It should, therefore, not be given to patients in severe heart failure, hypotension or shock, or with high-degree atrioventricular, intraventricular or sinoatrial block.
