We report a case of probable contrast-induced neurotoxicity that followed a technically challenging cardiac catheterization in a 69-year-old woman. The procedure had involved the administration of a large cumulative dose of an iodinated, nonionic contrast medium into the innominate artery: twelve hours following the catheterization, the patient developed a seizure followed by a left hemiplegia, and an initial computed tomography (CT) scan showed sulcal effacement in the right cerebral hemisphere due to cerebral swelling. The patient's clinical symptoms resolved within 24 hours, and magnetic resonance imaging at 32 hours showed resolution of swelling. Contrast-induced neurotoxicity should be found in the differential diagnosis of acute neurological deficits occurring after radiological procedures involving iodinated contrast media, whether ionic or nonionic.

The International Diabetes Federation (IDF) and the American Diabetes Association (ADA) have introduced specific criteria to define the 'optimization' of the metabolic state and glycaemic 'remission' of type 2 diabetes mellitus (T2DM) after bariatric surgery, respectively. Our objective was to assess the percentage of patients achieving these criteria. Data were collected for body mass index, glycaemic markers, lipids, blood pressure, hypoglycaemia and medication usage from 396 morbidly obese T2DM patients who underwent bariatric surgery in two centres and followed up for 2 years. At year 1, 14% of patients achieved the IDF criteria and 38% the ADA criteria, whereas at 2 years 8 and 9% satisfied these criteria, respectively. A relatively low proportion of patients achieved optimization of the metabolic state and T2DM remission. These patients may potentially benefit from the combination of bariatric surgery and adjuvant medical therapy to achieve optimal metabolic outcomes.
