Methylbromide intoxication: a case report.

This work focuses on the neurophysiological features in a patient with action myoclonus and mental deterioration following methylbromide intoxication. The patient is a 28-year-old man, without respiratory distress or exposure to other toxics. Myoclonus improved with polytherapy (clonazepam, 5-HT, carbidopa, GABA). The neurophysiological and neuropsychological evidence in this patient suggests a possible double site of action of methylbromide at cortical and subcortical levels.

[Acute segmental hemorrhagic penicillin-associated colitis].

Four days after beginning a perioperative antibiotic prophylaxis with amoxicillin and clavulanic acid a 33-year-old patient developed an acute haemorrhagic diarrhoea with cramp-like lower abdominal pain. Coloscopy revealed diffuse mucosal oedema with map-like ulcerations, increased susceptibility to trauma and submucous haemorrhages extending from the middle of the ascending to the middle of the descending colon. Granulocytic inflammation with cryptal atrophy was seen histologically. Stool cultures, including tests for Clostridium difficile toxin, were normal. All symptoms disappeared within three days of discontinuing the medication. Coloscopy after one week revealed marked improvement, after three months nothing abnormal. Acute segmental haemorrhagic penicillin-associated colitis is rare and must be distinguished from antibiotic-associated pseudomembranous colitis.

[Systemic thrombolysis using streptokinase. Experiences at the Civic Hospital of Lugano in the framework of the ISIS-2 study].

With a small group of Swiss hospitals we had an opportunity of participating in ISIS-2, the major study on thrombolysis in acute myocardial infarction. Experience with our microcosm (Ospedale Civico Lugano) was compared with the macrocosm of the results of ISIS-2 in 17,187 randomized patients (in brackets). Mortality was 5.1% (7.8%) in our streptokinase group and 15.8% (12.8%) in our placebo group. In the ISIS-2 study the combination of thrombolytic therapy with streptokinase, and of antiplatelet therapy with aspirin, showed a reduction of approximately one third in acute mortality of myocardial infarction, stroke and reinfarction. Our experience confirms the reduced incidence of allergic side effects (3.5%), major bleeding (0.3%) and minor bleeding (2.9%) during or after thrombolytic therapy.

Brain-stem auditory evoked potentials (BAEPs) and magnetic resonance imaging (MRI) in a case of facial myokymia.

The case of a 37-year-old woman with facial myokymia is reported. Magnetic resonance imaging (MRI), electromyography (EMG) and brain-stem auditory evoked potentials (BAEPs) supported the clinical diagnosis of suspected multiple sclerosis (MS). MRI showed a single area of abnormal signal in the pontine region. The authors discuss the possible relationship between the brain-stem lesion and the electrophysiological abnormalities demonstrated by BAEPs and the EMG of facial muscles.
