Motor evoked potentials after magnetic transcranial stimulation and the excitability of the motor cortex to increasing magnetic stimulus intensities were evaluated in six patients with hemiparesis after ischaemic stroke within 8 hours after stroke. The latencies of motor evoked potentials were normal in all patients. ⋯ This finding was associated with a poor motor recovery and the NIH score after 15 days was unchanged (NIH score 1.75 (SD 1.5)). The present data suggest that the evaluation of the excitability of motor cortex may offer a mean of predicting functional outcome following stroke.

A 55-year-old man developed acute respiratory failure, pulmonary hypertension and left heart failure due to acute myocardial infarction. Nitric oxide (NO) inhalation improved arterial oxygenation, decreased pulmonary arterial pressure and increased cardiac output (CO), but combined use of dobutamine with NO produced increases in pulmonary arterial pressure and pulmonary capillary wedge pressure (PCWP). In this patient, amrinone decreased pulmonary arterial pressure and PCWP, and increased PaO2/FiO2 effectively while increasing CO. Combined use of inhaled NO and intravenous amrinone may have beneficial effects for a patient with acute respiratory and cardiac failure.

Intravenous urography (IVU) is a useful radiographic study in the detection of renal and ureteral calculi. However, it is time consuming, expensive, and exposes the patient to i.v. contrast and radiation. To determine the impact of utilizing IVU less for the detection of renal calculi, criteria for ordering IVU in the emergency department (ED) were evaluated, and patients with high probability of positive IVU were identified. ⋯ The combined objective findings of acute flank pain and haematuria are sensitive, and prior history is specific in identifying patients with renal calculi. Degree of haematuria was not useful in predicting renal calculi. By utilizing the criteria of acute flank pain and haematuria as a decision aid, 66% of all IVUs ordered could have been avoided.

Comparative Study
Advanced trauma life support (ATLS) courses: should training be refocused towards rural physicians?
Recently there has been an increase in the number of courses designed to improve the theoretical knowledge and practical skills of health workers for immediate emergency management under life-threatening conditions. However, the numbers of applicants for these courses far exceed the available places. Priorities should be reviewed to solve the current shortfall. ⋯ Furthermore, the net gain was significantly higher (p < 0.05). Efforts should be made to increase the participation of paediatricians practising in rural level II trauma centres in trauma care courses. Further research should address the applicability of these results for recruiting primary care physicians to the ATLS courses.

We report the case of a 30-year-old male, heroin dependent, receiving methadone treatment, who, while staying at home, ingested 50 mg of naltrexone. He immediately developed serious withdrawal symptoms and was admitted to the hospital. In the emergency department the drugs given to counteract the agitation were ineffective, and the patient developed respiratory distress. ⋯ Afterwards he did not attend his scheduled outpatient follow-up visits. Treatment with propofol is effective in the case of a patient with a serious withdrawal syndrome secondary to naltrexone overdose during methadone therapy. Despite the actual possibility of getting through the withdrawal symptoms the patient failed to return for follow-up visits, which might be related to a lack of motivation.
