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.     

Radiation dose reduction during hysterosalpingography: an application of scanning-beam digital radiography

Hysterosalpingography was performed in 31 patients by means of a low-dose scanning-beam digital radiographic system. The technique permits adequate evaluation of gynecologic abnormalities while allowing significant reduction in radiation: 2.4-mR (6.1 X 10(-7) C/kg) exposure to the skin and 0.7-mrad (7 X 10(-6) Gy) mean dose to the ovaries per image obtained. Sixteen patients demonstrated readily recognizable and documented abnormalities, corroborated by laparoscopy, laparotomy, or other supportive evidence.     

Cyclosporin-A nephrotoxicity and acute cellular rejection in renal transplant recipients: correlation between radionuclide and histologic findings

Serial radionuclide studies using both Tc-99m DTPA (perfusion) and I-131 hippuran (tubular function) were correlated with histologic findings in 25 patients with renal transplants. These cases included 15 cases of cyclosporin-A nephrotoxicity (CsA-NT) and ten cases of acute cellular rejection that were retrospectively selected on the basis of biopsy findings and favorable clinical response to therapy specific for each of these conditions. The serial radionuclide studies enabled the correct diagnosis in 12 of 15 cases of CsA-NT and eight of ten cases of acute rejection. Posttherapy radionuclide studies, furthermore, demonstrated improvement consistent with clinical response. In all cases, the radionuclide results were available at least 24 hours before biopsy findings. These results indicate that serial radionuclide studies evaluating interval changes in both perfusion and tubular function are of significant value in the diagnosis and follow-up of CsA-NT and acute cellular rejection in transplant recipients. This initial experience suggests a sensitivity of 80%.     

Effectiveness of early orthodontic treatment with the Twin-block appliance: a multicenter, randomized, controlled trial. Part 1: Dental and skeletal effects.

This study evaluated the effectiveness of early orthodontic treatment with the Twin-block appliance for the developing Class II Division 1 malocclusion. This multicenter trial was carried out in the United Kingdom. A total of 174 children, aged 8 to 10 years old, with Class II Division 1 malocclusion were randomly allocated to receive treatment with a Twin-block appliance or to an untreated, control group. Data were collected at the start of the study and 15 months later. Results showed that early treatment with Twin-block appliances resulted in reduction of overjet, correction of molar relationships, and reduction in severity of malocclusion. Most of this correction was due to dentoalveolar change, but some was due to favorable skeletal change. Early treatment with the Twin-block appliance is effective in reducing overjet and severity of malocclusion. The small change in the skeletal relationship might not be considered clinically significant.     

Protection against hyperglycemia in female nonobese diabetic mice treated with 15-deoxyspergualin.

The effects of 15-deoxyspergualin (15-DS), a newly described immunosuppressive agent, have been studied on the development of diabetes in female NOD mice. 15-DS treatment was started two weeks after weaning i.e. at five weeks of age. The mice received either one daily intraperitoneal injection of 15-DS (2.5 mg/kg body weight) or saline for two weeks. The mice were then injected every third day up to eight months of age for evaluation of the diabetes incidence. In another set of experiments the mice were treated up to three months of age, whereafter islet insulin release, islet insulin content and DNA content was measured together with an evaluation of spleen cell proliferation rates. Different spleen cell subsets were studied directly after the two weeks of daily injections. In the saline group 8 out of 9 mice developed diabetes, whereas only 4 out of 11 of the 15-DS treated mice became diabetic (p < 0.05). There was no difference between the groups in islet insulin release in response to glucose, however, the islet insulin release increased after one week in culture. The 15-DS treatment did not affect the insulin or DNA content of the isolated islets or the insulin concentration in the pancreas. No detectable changes in the relative number of CD4+ and CD8+ T-cell subsets in the spleen were seen and there were no obvious differences in splenocyte proliferation rates. The histological examinations of the pancreatic glands showed gradual increasing signs of islet inflammation with age and 15-DS could apparently not prevent this.(ABSTRACT TRUNCATED AT 250 WORDS)     

Urinary output of endogenous monoamine oxidase inhibitor and isatin during acute migraine attacks

Summary Urinary output of endogenous monoamine oxidase (MAO) inhibitory activity, was significantly raised in serial samples collected across a migraine attack compared with collections during attack-free periods and in healthy controls, which did not differ from each other. There was a highly significant correlation in output between isatin, a major fraction of the MAO inhibitory activity, and output of the MAO inhibitory activity itself. However, although there was a tendency towards increased isatin excretion during migraine attacks, it failed to reach statistical significance.
