    Changes in paranasal sinus abnormalities found incidentally on MRI (1995)

    Neuroradiology 37 (1995), S. 471-474

    Notes: Abstract Abnormal opacification of paranasal sinuses on brain MRI was studied in 178 consecutive adult patients who underwent two examinations separated by at least 4 months because of suspected neurological disease. Sinus abnormality was present in 79 (44%) patients; in 60% the abnormality involved two or more sinuses and it was bilateral in 51%. The most frequently abnormal sinus was the maxillary (46%), followed by the ethmoid (32%), sphenoid (16%), and frontal sinuses (6%). Interval occurrence or complete resolution of abnormalities was observed in 52% of patients (66% of the sinuses). In the remaining 48% of patients the abnormalities were present on two or more examinations, unchanged or of increased or decreased severity. The most frequent interval changing abnormalities were complete sinus opacification and fluid levels, followed by irregular mucoperiosteal thickening more than 4 mm thick. No polypoid abnormalities (polyps or mucosal cysts) decreased over time.

    Sex and age related differences in postmyelographic adverse reactions (1989)
    Springer
    Neuroradiology 31 (1989), S. 331-335

    Notes: Summary Differences in frequency of postmyelographic adverse reactions were analyzed with respect to sex and age in a prospective study including 1026 patients injected with metrizamide and 739 injected with iohexol. Regardless of the type of contrast medium or myelography, all types of adverse reactions were 1.4–3.8 times as frequent in women as in men. Most of the differences were statistically significant. Headache was more frequent, while vomiting and dizziness were less frequent in both women and men aged 26–50 years compared with those over 50 years of age. Dizziness and increased low back pain were consistently reported spontaneously by the patients less frequently than emerged via formal interview. The large differences between the sexes suggest that further research on contrast media toxicity would be best performed with separation of the data by gender.
