448. Cisplatin-induced non-convulsive posterior reversible encephalopathy syndrome in a 41-year-old woman with metastatic malignant melanomaJanja Ocvirk, Marko Boc, Martina Reberšek, Tanja Roš-Opaškar, 2009, original scientific article Abstract: Background. Cisplatin, a widely used antineoplastic agent usually induces peripheral neuropathy, but can rarely also complicate with encephalopathy, with or without seizures. Case report. We report a case of a young patient with metastatic malignant melanoma with signs and symptoms of cisplatin-induced non-convulsive posterior reversible encephalopaty syndrome. Within the days shortly after the first cycle of cisplatin based chemotherapy the patient suffered from nausea, vomitus, headache, severe pain at the site of sub-cutaneous metastases and confusion. She later experienced somnolence, cortical blindness and aphasia, but without epileptic seizures. Conclusions. Cisplatin is an effective chemotherapeutic drug but also very toxic one and physicians using it must also be aware of possible encephalopathy.

450. Influence of magnesium sulphate infusion before total thyroidectomy on transient hypocalcemia - a randomised studyNikola Bešić, Špela Žagar, Gašper Pilko, Barbara Perić, Marko Hočevar, 2008, original scientific article Abstract: Background. Transient hypocalcemia is the most common complication after thyroidectomy. Normomagnesemia is needed for normal secretion of PTH and end-organ responsiveness. Our aim was to determine the influence of infusion of magnesium sulphate before thyroidectomy on the incidence of laboratory and clinical transient hypocalcemia. Methods. In our prospective study, 48 patients (5 men, 43 women; age 22-73 years, median 45 years), who underwent total or near-total thyroidectomy, were randomised preoperatively. Half of them received intravenously 4 ml of 1M magnesium sulphate at the beginning of the surgical procedure, the other half were the control group. Serum concentrations of calcium, ionised calcium, magnesium, phosphate, albumin and PTH were measured prior to surgery and on the first day after surgery. Results. Laboratory postoperative hypocalcemia was present in 27% of patients and 23% of patients had clinical signs and/or symptoms of postoperative hypocalcemia. The concentration of total calcium (p=0.024) and of albumin (p=0.01) was lower in the group that received magnesium sulphate. Conclusions.The patients who received infusion of magnesium sulphate before total thyroidectomy had lower concentration of total serum calcium and albuminin comparison to the control group. There was no statistical differencein the incidence of clinical transient hypocalcemia.
