Alcoholic ketoacidosis: a case report

A 43-year-old alcoholic presented in coma with ketoacidosis, after three days of nausea and feeling generally unwell, which had been preceded by a prolonged three-week period of heavy alcohol consumption with poor dietary intake. The acidosis responded rapidly to intravenous dextrose. This is the first Scottish report of a case of alcoholic ketoacidosis.     

Early cardiovascular changes with ibopamine: evidence for a biphasic haemodynamic action.

1. The haemodynamic effects of ibopamine, an oral dopamine derivative, were studied in eight patients with left ventricular dysfunction using invasive catheterisation techniques. 2. An early rise was seen in the mean right atrial pressure (P less than 0.05), the mean capillary wedge pressure (P less than 0.01) and the mean pulmonary arterial pressure (P less than 0.001) which occurred at 15 min and persisted for 30 min. 3. A second, later, positive chronotropic effect was seen as an increase in the heart rate (P less than 0.05) at 45 min with an increased cardiac output (P less than 0.05) persisting above baseline values at 1 h, but with no change in stroke volume. 4. These results support a biphasic mode of action for ibopamine which may be explained by a time phase difference in alpha- and beta-adrenoceptor stimulatory effects.

Anulus fibrosus in bulging intervertebral disks

In this investigation the association of radial tears of the anulus fibrosus and bulging of the intervertebral disk was studied. An index of disk bulging was measured in sagittal anatomic sections in 149 lumbar disks from 31 cadavers. The indexes of disk bulging were correlated with stages of disk development and the presence of an annular tear. The largest disk-bulging indexes were always associated with radial tears of the anulus. Eighty-four percent of the disks with radial tears had disk-bulging indexes greater than 2.5 mm. Most normal adult disks had an index of less than 2.5 mm. The results challenge the concept that the anulus fibrosus is intact in bulging disks, although ruptured in herniated disks.     

Red cell antigens and renal transplantation

Donor-specific transfusion was performed with and without cyclosporine between haplomismatched relatives prior to living-donor renal transplantation. Red cell antigen mismatching was not taken as a contraindication to DST. Of 80 patients included in the trial; eleven were ABO-mismatched, 15 were Rh(D)-mismatched, and a further 11 were transfused in the presence of atypical red cell antibodies (anti-D, -C, -Fya, -Kell -N, -H/I -I, -P1, -Wra). Patients were randomized to receive cyclosporine (10 mg/kg) daily during DST or not (control group). The presence of atypical red cell antibodies, with the exception of Rh anti-D, did not appear to influence DST or renal transplantation. DST did not act as a primary stimulus to Rh anti-D production but stimulated preexisting anti D levels. ABO mismatching did not appear to influence DST or subsequent renal transplantation except in one group A [corrected] patient who received group O [corrected] blood and cyclosporine. This patient developed a severe, but self-limiting, autoimmune hemolytic anemia due to auto-anti A antibodies. A similar group A patient in the control group developed an auto-antibody with no clinical sequelae. The influence of cyclosporine on the development of this auto-antibody is uncertain. We conclude that, with the exception of preexisting anti-D antibodies, minor red cell antigen disparities should not preclude pretransplant conditioning with donor-specific transfusions.
