Early detection of breast cancer is gaining importance because it leads to reduction of morbidity and mortality rates of this disease. Detection of infraclinical tumors is best accomplished by ...mammography because of its high sensitivity. Ultrasonography and MR mammography play a complementary role. Ductal carcinoma in situ as well as small invasive tumors can be clinically occult malignant tumors. Preoperative marking should be performed in suspected breast lesions, preferentially by means of a hookwire or carbon. Surgical removal of the lesion is to be verified by intraoperative specimen radiography.
We describe the clinical and neuroradiological findings in a 63-year-old man with Parinaud's syndrome. Magnetic resonance (MR) imaging showed a mass lesion within the quadrigeminal plate. Additional ...MR findings included a right frontoparietal subcortical lesion as well as periventricular white matter edema due to acute deterioration of hydrocephalus. On MR, the diagnosis of multifocal glioma was proposed. Neuropathological examination after resection of the supratentorial lesion revealed an oligodendroglioma, grade II.
Options in parenteral therapy increasingly require administration of several medications simultaneously. Very little is known about the compatibility and pharmacological stability of such mixtures. ...We investigated how widespread this practice is, which carrier solutions are most commonly used, and whether specific medication mixtures ('cocktails') or constant formulations for TPN are applied. Upon our request, physicians and nursing staff of 54 general hospital wards (19 surgical, 18 internal medicine, 17 intensive care) in 17 Austrian hospitals recorded the parenteral admixtures for one week under the supervision of a hospital pharmacist. We found that: 1. Admixing is commonly practiced in all wards. In all but one of the wards two or even more medications are added into one single infusion. 2. Carrier solutions were: Dextrose/fructose (87% of the wards), electrolytes (90%), amino acids (40%), fat emulsions (26%), colloids (14.8%), albumin (5.5%) and Solcoseryl (5.5%). 3. Fixed combinations for i.v. therapy are practiced in 70% of the wards (mostly analgetics with corticosteroids or vitamins) 4. In almost half of the units constant formulations for TPN exist (46%). Only few of the combinations named have been investigated or tested for stability. The compatibility of most of the admixtures is unknown, while a few are clearly incompatible. Admixtures to one of the carrier solutions (Solcoseryl) are known to have caused serious complications before. For several admixtures, conflicting data about compatibility were found in the literature. The theoretical basis for incompatibilities is discussed together with some typical examples. Also some rules for admixtures are given. Questions concerning the compatibility of simultaneous parenteral drug applications are too specific to be answered for most physicians. Advice and counseling on this subject should become a new task for clinical pharmacists.
