Staples for wound closure: a controlled trial.

Skin staples were compared with two conventional suture methods for speed, convenience, effectiveness and cost. One hundred and ninety-five patients having linear abdominal incisions were randomly allocated to one of three methods of interrupted skin closure--polypropylene sutures, polyglactin sutures or stainless steel staples and the wounds were assessed over 30 days. The mean rate of wound closure using sutures was 4.

Primary hyperparathyroidism in German shepherd dogs: a disorder of probable genetic origin.

Primary hyperparathyroidism was diagnosed in two German shepherd pups from a litter of four females. Clinical signs were apparent by two weeks of age and included stunted growth, muscular weakness, and polydipsia/polyuria. Radiography revealed diffuse reduction in bone density.

The measured effect of stopping smoking on intermittent claudication.

One hundred and twenty-four limbs in patients suffering from intermittent claudication were studied over 10 months. Changes in ankle pressure and treadmill exercise tolerance over the period were compared between two groups, one of patients who continued to smoke (group 1) and the other of those who gave up (group 2). Resting ankle systolic pressure fell in smokers' limbs by a mean of 10.

Relationship between condylomata and laryngeal papillomata. Clinical and molecular virological evidence.

In a survey of 49 papilloma patients accurate maternal condyloma history was obtained in 31 instances and of these, 21 were positive for the presence of condyloma during pregnancy or parturition. Molecular virological studies indicate that positive hybridization could be demonstrated to human papilloma virus 2 in both laryngeal papilloma and condyloma by the Southern blot technique. Immunoperoxidase staining illustrated the presence of virus-related particles only near the surface of the mucous membrane papilloma, which is in contrast to the definite staining of the stratum granulosum and stratum corneum of verrucae.

Physiologic features of the canine esophagus: effect of modified Heller's esophagomyotomy.

The effects of the modified Heller's esophagomyotomy on function of the lower esophageal sphincter in the dog were studied. In normal dogs, this surgical procedure produced a les competent lower esophageal sphincter that still maintained the ability to prevent esophageal reflux.

Giant cell tumors of the maxilla in children.

Three types of giant cell lesions occur in the facial skeleton; namely, giant cell reparative granuloma, Brown tumor of hyperparathyroidism, and true giant cell tumor -- osteoclastoma preferably called giant cell neoplasm. An appraisal of the clinical course biochemical laboratory data, radiographic appearance, and histological features are all necessary to distinguish between these varieties. Differentiation is a prerequisite to treatment because the management differs in each lesion.

Frequency and significance of epithelial atypia in laryngeal papillomatosis.

The clinical records and microscopic sections from 32 patients were reviewed in an attempt to correlate histopathologic features with clinical behavior. Three general clinical groups were identified on the basis of recurrence rates and extent of papillomatosis. In those lesions with the highest frequency of recurrences, epithelial atypia tended to be most pronounced.
