ABSTRACT
PURPOSE: The purpose of this study was to assess the effect of magnesium supplementation on total magnesium, ionized magnesium, ionized calcium, potassium, and pH in critically ill cancer patients and to compare the validity of the measurements. MATERIALS AND METHODS: Thirty-three consecutive critically ill patients receiving magnesium supplementation were placed in this prospective observational study at the Comprehensive Cancer Center, University Hospital. One gram (4.1 mmol) magnesium in 50 mL D5W was administered to critically ill patients, and the following were measured: total magnesium, ionized magnesium, ionized calcium, potassium, albumin, pH, BUN, creatinine, creatinine. RESULTS: Total magnesium and ionized magnesium increased by a mean of .11 +/- .02 and .05 +/- .01 mmol/L, respectively, after supplementation with 4.1 mmol of magnesium sulfate (P = .0001). Total magnesium, ionized magnesium, albumin, ionized calcium, potassium, and pH did not change significantly by the administration of 1 g of magnesium sulfate. CONCLUSION: The mean ionized magnesium (IMg+2) relationship to total magnesium (TMg) cannot be predicted before the supplementation with the available technology. After supplementation of 4.1 mmol/L the ionized magnesium level increased by .05 +/- .01 mmol/L. Magnesium supplementation had no significant effect on ionized calcium, potassium, and pH. TMg and IMg+2 should be followed independently.

Human echinococcosis is endemic disease that occurs in some regions of Yugoslavia. It is caused by tapeworm Echinococcus granulosus, whose larva can develop cysts in liver and other organs. In the study were presented 119 patients with hepatic echinococcosis, 57 (47.9%) females of average age 41.4 years (9-80) and 62 (52.1%) males of average age 35.5 years (6.72). Primary echinococcosis was present in 75 (63%), and recurrent in 44 (37%) patients. Right lobe of liver was affected in 83 (69.7%), left in 17 (14.3%) and both lobes in 19 (16%) of cases. The complications of hepatic echinococcosis such as cyst infection, cholestasis, cyst rupture in biliary tract and liver fibrosis were observed in 20 (16.8%) patients. Indirect immunofluorescence antibody test was positive in 91 out of 119 (68.1%) patients, and hemagglutination inhibition test was positive in 56 out of 77 (72.7%) patients. Surgically were treated 57 (47.9%) patients, and 41 of them received antihelminithic drugs pre and/or postoperatively. Disease recurrence was observed in 4 (7%) patients. Percutaneous puncture and drainage of echinococcus cyst with simultaneous albendazole administration was performed in 12 (10%) patients. In three of them liver abscess was developed during drainage, and for that reason, two patients had to be surgically treated. Ten (83.3%) patients were completely cured. Medicamentous therapy as the only treatment was used in 31 (26.1%) patients, 9 patients received mebendazole, 19 received albendazole and 3 patients received praziquantel. The success was achieved in 10 (32.3%) patients. Out of the total number, 19 (16%) patients were not treated at all. Surgical removal of the cyst takes a leading place in the treatment of hepatic echinococcosis. However, in well-selected cases and in the patients with high surgical risk, antihelminithic therapy and percutaneous drainage of echinococcus cyst are of more significance.

In 22 patients with alimentary toxoinfection caused by salmonella and other gram-negative bacteria, endotoxemia was proved in 8 (36%) patients. The causative agent of the disease was proved in 11 (50%) of cases. In 6 (54%) patients the causative agent were from salmonella species: S. enteritidis, S. typhimurioum, S. hadar and S. heidelberg. Endotoxemia and positive coprocultures, that is, hemocultures were found in two patients respectively. In two patients with positive coprocultures and hemocultures, endotoxemia was found as well as in two patients with unknown causative agent. In patients with alimentary toxoinfection caused by salmonella and other gram-negative bacteria, endotoxemia occurred relatively often. Early detection of endotoxemia is important for application of urgent therapeutic measures and procedures, especially in immunocompromised patients.

Clinical characteristics of Lyme disease were analysed in 22 patients. Erythema migrans was found in 20 (91%), arthralgia in 18 (81%), neuralgia in 8 (36%), encephalitis in 3 (13%), carditis in 2 (9%) and arthritis in 2 (9%) patients. The positive antibody titer was found in 14 (63%) patients. Favourable effects of antibiotic therapy was achieved in all patients. Erythema migrans has been manifested up to 12 days after tick sting and arthralgia, arthritis, neuralgia, hepatitis and chronic dermatitis within a year. Carditis and encephalitis have been developing from a month to ten years after tick sting. Lyme borreliosis is commonly manifested as a systemic disease. Together with the skin, most commonly have been involved ankle joints, heart and nervous system. The time from tick sting to the onset of first signs of the diseases varies by the involved organs.
