The problems of clinical measurement of pain are considered. Various adjuncts to the standard clinical interview are proposed. ⋯ Correlations between various pain measures are shown. The use of the weekly pain chart by doctors is recommended in cases of chronic pain.

Lymphocytes lacking receptors for sheep erythrocytes and surface immunoglobulin were present in the blood in large numbers at some stage in four cases of chronic lymphocytic leukaemia (which included a mother and son), and formed a substantial proportion of the circulating lymphocytes in other cases. These null cells possessed receptors for mouse erythrocytes. Other B-cell markers were also found on these cells. Serial studies showed a great variation in the number of null cells during the course of the disease (which may be associated with treatment), suggesting variation in the the maturation of leukaemic cells, and indicating that the surface marker complement may not reflect the constitution of the cell undergoing the original malignant change.

Case Reports
Plasmapheresis in the treatment of thrombotic thrombocytopenic purpura: a report of five cases.
Thrombotic thrombocytopenic purpura, an acute clinical disorder of uncertain aetiology, has previously been associated with almost 100% mortality. Dramatic response to exchange transfusion has been reported, and there is some evidence that a circulating immune complex may be involved in the pathogenesis. ⋯ Three patients showed a dramatic response, which was manifested by rapid correction of the neurological deficit and of the abnormalities in laboratory findings. We conclude that the thrombotic thrombocytopenic syndrome should be regarded as an indication for emergency plasma exchange.

Cefamandole, a new cephalosporin derivative, has been used in treatment of six patients who had diminished renal function and respiratory infections, and of 14 patients with urinary tract infections (UTI). Infection was eliminated in all patients with respiratory infections, and in seven of the patients with UTI. No serious side effects were encountered and, even in patients with pre-existing renal dysfunction, no reduction in renal function occurred.
