The changing mammogram. A primary indication for needle localization biopsy.

Screening mammography results in improved detection and survival for women with breast cancer. Interval mammographic changes may be one of the major indications for biopsy. Four hundred fifty-two needle localization biopsies carried out for microcalcifications, mass, asymmetric density, or a combination of calcifications with mass or asymmetric density detected 95 cancers (21%). Interval mammographic changes detected 35 cases (17.9%). Invasive cancers constituted 51% of the initial group but only 34% of the cancers detected because of interval change. Benign breast disease occurred in 160 of 195 women who had undergone biopsy because of interval changes. These changes continued into the postmenopausal period. Hyperplasia and/or atypia was found in 57 (35%) of 160 of the interval group. Interval mammographic abnormalities detect significant pathologic changes in the breast and should be considered a major indication for breast biopsy.

Molecular characterization of a cytoplasmic dynein from Dictyostelium.

Cytoplasmic dynein is a high molecular weight, microtubule-based mechanochemical ATPase that is believed to provide motive force for a number of intracellular motilities, including transport of membrane-bound organelles. Cytoplasmic dynein also localizes to the mitotic spindles of some organisms and to the kinetochore regions of some condensed chromosomes, where it may play an active role in spindle assembly, spindle position, and/or chromosome movement during cell division. Despite active research efforts from a number of laboratories, little detail is yet available about dynein-based cellular activities. This paper describes our efforts to characterize cytoplasmic dynein from Dictyostelium and to use this protist as a molecular genetic factory to probe structure-function relationships of this molecule.

Magnetic resonance imaging of iliotibial band syndrome.

Seven cases of iliotibial band syndrome and the pathoanatomic findings of each, as demonstrated by magnetic resonance imaging, are presented. These findings were compared with magnetic resonance imaging scans of 10 age- and sex-matched control knees without evidence of lateral knee pain. Magnetic resonance imaging signal consistent with fluid was seen deep to the iliotibial band in the region of the lateral femoral epicondyle in five of the seven cases. Additionally, when compared with the control group, patients with iliotibial band syndrome demonstrated a significantly thicker iliotibial band over the lateral femoral epicondyle (P < 0.05). Thickness of the iliotibial band in the disease group was 5.49 +/- 2.12 mm, as opposed to 2.52 +/- 1.56 mm in the control group. Cadaveric dissections were performed on 10 normal knees to further elucidate the exact nature of the area under the iliotibial band. A potential space, i.e., a bursa, was found between the iliotibial band and the knee capsule. This series suggests that magnetic resonance imaging demonstrates objective evidence of iliotibial band syndrome and can be helpful when a definitive diagnosis is essential. Furthermore, correlated with anatomic dissection, magnetic resonance imaging identifies this as a problem within a bursa beneath the iliotibial band and not a problem within the knee joint.
