Concentrations of 50 major and trace elements in Danish agricultural crops measured by inductively coupled plasma mass spectrometry. 3. Potato (Solanum tuberosum folva).

The multi-element (Ag, Al, Au, Ba, Bi, Ca, Cd, Co, Cr, Cs, Cu, Dy, Er, Fe, Ga, Gd, Ho, In, Ir, La, Lu, Mn, Mo, Nb, Nd, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Ru, Sb, Sc, Sm, Sn, Sr, Ta, Tb, Th, Ti, Tl, Tm, U, V, Y, Yb, and Zn) concentrations (microg/kg, fresh weight) in potatoes (Solanum tuberosum, Folva) were investigated in this study. The potatoes were grown in two fertilization practices; one with pig slurry and one with calcium ammonium nitrate at three levels of N fertilization (0, 60, and 120 kg of N/ha). The experiment field was located at the Riso National Laboratory Agronomy Farms in Roskilde, Denmark. High-resolution-inductively coupled plasma mass spectrometry (HR-ICPMS) was used for analyses of the samples. The effect of three levels of N fertilization on elemental concentrations of the crop are evaluated by use of discriminant partial least-squares regression (PLS). The results provide useful biological and nutritional information on potatoes.

[Atypical mycobacteria. Disseminated infection in patients with hematologic diseases]. / Atypiske mykobakterier. Dissemineret infektion hos hoematologiske patienter.

During the last decade interest in atypical mycobacteria (AM), especially Mycobacterium avium complex (MAC) has been intense, as a large number of AIDS patients develop disseminated infection with MAC. Disseminated infection has also been reported in other immunocompromised patients, but in much fewer cases. Among haematological diseases hairy cell leukemia (HCL) and chronic myelogenous leukemia (CML) seem to predispose to disseminated AM infection. We review 53 cases of disseminated AM infection in haematological patients reported in the literature, 39 with HCL, ten CML, and four other haematological diseases, and a review of possible treatment is given. The prognosis seems to depend on the course of the underlying haematological disease, and we conclude that early diagnosis and treatment of the infection is of great importance. Blood and bone marrow should therefore be cultivated for mycobacteria in such patients with persistent fever of unknown cause, and in cases with negative cultures and elevated serum values of alkaline phosphatase liver biopsy should be considered.

[Disseminated Mycobacterium avium infection in three patients with hematologic diseases]. / Dissemineret Mycobacterium avium-infektion hos tre haematologiske patienter.

We report three cases of disseminated Mycobacterium avium complex infection in immunocompromised haematological patients. We conclude that in haematological patients with longlasting fever of unknown cause Mycobacterium avium complex infection should be considered and the relevant cultures from blood and bone marrow should be done.

The influence of antimicrobial prophylaxis on the microbial and clinical findings in patients after autologous bone marrow transplantation.

The influence of a prophylactic regimen consisting of ciprofloxacin 250 mg bid, was examined by surveillance cultures from nose, throat, axilla, gingiva, exit site of central venous catheters, blood, rectum and urine of 60 patients undergoing autologous bone marrow transplantation during a 6-year period. None of the 60 patients developed any infectious with Gram-negative rods belonging to the Enterobacteriaceae, or deep fungal infections, during hospitalization. All patients were neutropenic. Febrile episodes were seen in all patients but 3. From 13 patients, microorganisms in the blood, mostly nonhaemolytic streptococci (9/13), were cultured. Surveillance cultures did not predict later infections, but revealed the marked influence of the prophylactic antibiotics on the normal flora. Thus, mainly streptococci, coagulase-negative staphylococci and yeasts were cultured from the sites examined. It is concluded that the future objective of the microbiological surveillance should be restricted to monitoring the possible selection of drug-resistant microorganisms, and that routine cultures of blood and urine are unnecessary.

[Spread of an imported multiresistant Staphylococcus aureus to other hospitals via secondary colonized patients]. / Spredning af en importeret multiresistent Staphylococcus aureus til andre sygehuse via sekundaert koloniserede patienter.

UNLABELLED: A secondary spread of an imported methicillin-resistant Staphylococcus aureus strain (MRSA) to two other patients occurred within a Danish surgical ward in spite of isolation of a multitraumatized index-patient immediately after arrival from a hospital in the Mediterranean area. The two other colonized patients were later transferred to other hospitals in Denmark where it became apparent that they had developed serious infections with the MRSA strain. IN CONCLUSION: to prevent spread of imported MRSA within Danish hospitals, strict adherence to isolation procedures and a high level of general hygiene is essential not only when patients are transferred from hospitals situated in endemic areas of MRSA abroad, but also when admitted from Danish hospital wards where known cases of colonisation or infection with MRSA exist.

[Kasabach-Merritt syndrome]. / Kasabach Merritt-syndrom.

Kasabach Merritt syndrome, first recognized in 1940, is characterized by haemangiomatosis, thrombocytopenia and intravascular coagulation. It is most often seen in children, rarely in adults. The mortality rate is 20-30%. Treatment is by removing the haemangiomatosis and correcting the consumptive coagulopathy. The purpose of this paper is to present a patient with Kasabach Merritt syndrome with haemangiomatosis in the spleen and the liver. A review of the relevant literature is given.
