Is what you see what you get? Breast specimen handling re-visited.

Specimen radiography is already established as an essential adjunct to excisional biopsy of mammographically detected abnormalities. Two methods of specimen sectioning following the initial specimen radiograph are described. The techniques were devised to identify the lesion accurately in the specimen for subsequent pathological analysis. They have been tailored to suit the differing facilities at two Breast Screening Centres. The methods highlight the desirability of a cooperative multidisciplinary approach to the management of breast disease. They underline the importance of radiological localization of the lesion; not only for the surgeon, but also for the pathologist.

Recurrent secondary hyperparathyroidism due to implanted parathyroid tissue: a case report.

Hyperparathyroidism is a common complication of chronic renal failure. Although many patients can be managed by conservative measures, surgery is sometimes necessary. One of two operations can be performed: subtotal parathyroidectomy or total parathyroidectomy with reimplantation of parathyroid tissue into muscle. A case is presented of a patient who underwent the first and then the second of these procedures for recurrent hyperparathyroidism. A further recurrence was found to be caused by the implanted parathyroid tissue in a forearm muscle, requiring a third procedure for control of the disorder.

The wide-angle pattern electroretinogram. Relation between pattern electroretinogram amplitude and stimulus area using large stimuli.

Pattern electroretinograms (PERGs) were recorded from two normal human subjects in response to various spatial frequencies and stimulus areas. The maximum stimulus area was 75 degrees x 86 degrees which was achieved by using a standard TV monitor and a reduced viewing distance. The amplitude of the PERG increased with area in an approximately logarithmic fashion over the range investigated. The explanation relates to non-linearities of the stimulus, the retinal image and neural processing. The wide-angle PERG may be useful in the assessment of retinal diseases affecting the mid-peripheral inner retina, such as diabetic retinopathy.
