[Breast tumor--a diagnostic challenge]. / Tumor mammae--en diagnostisk utfordring.

The study includes all patients referred for surgical examination with suspected breast cancer (n = 439) during a single year. All women were examined clinically. Mammography was performed in 372 cases (88%), and 195 (46%) women underwent biopsy. 37 (8.7%) of the admitted women had breast cancer, which was verified by histological examination. This corresponds to an incidence rate of 0.8 per 1,000 women, and an incidence rate of 2.0 per 1,000 in women above 40 years. In four patients who were not suspected as having breast cancer after clinical examination, breast cancer was revealed by mammography. However, mammography alone is insufficient, since three mammograms were false negative, in cases where cancers were diagnosed clinically. Therefore, both mammography and clinical investigation are necessary in the examination of women with breast tumors. When breast cancer cannot be ruled out by physical and mammographic examination, a representative specimen of the tumor should be removed for histological or cytological examination.

Injuries to the hand inflicted by rotary snowcutters.

In the period January 1, 1975, through December 31, 1986, 28 patients were treated for hand injuries caused by small home rotary snowcutters. These injuries were characterized by extensive lacerations and contusions, particularly on the dorsal side of the hand and the fingers, with concomitant extensor tendon ruptures, comminuted and complicated fractures, and traumatic amputations of fingers of the dominant hand. The index and middle finger were nearly always injured; the thumb was usually totally spared. The frequency of postoperative complications was low after delayed primary surgical treatment. In this series the mean permanent medical disablement was found to be 12%, ranging from 0 to 50%. The present observations, when made available, alarmed national authorities. In turn, manufacturers were required to equip rotary snowcutters with motorquenchers. This device will probably effectively prevent these injuries in the future.
