Characteristics of bovine early puerperal uterine contractility recorded under farm conditions.

A non-invasive, digital technique was used to measure and quantify intrauterine pressure (IUP) changes in early postpartum dairy cows kept under farm conditions in order to document physiological changes in uterine contractility after uncomplicated calvings. In addition, possible relationships between characteristics of uterine contractility and blood ionized calcium (Ca(2+))-concentrations were investigated. Recordings of uterine contractility were made by using a transcervically inserted open tip catheter in 12 healthy cows during their first 48h after calving.

Survivorship analysis of hemiarthroplasties.

From 1976 until 1988, 679 hemiarthroplasties were inserted for displaced femoral neck fractures. Two hundred two were of the Austin Moore design (one-piece, noncemented), 209 of the Christiansen design (trunion bearing, cemented), and 268 of the Hastings design (bipolar, cemented). Five years after the hemiarthroplasty, the cumulative proportion of prostheses surviving was 90%, declining to 85% after ten years.

Years of potential life lost after hip fracture among postmenopausal women.

From January 1987 and onwards all cases of hip fracture in Arhus County, Denmark, were registered in a prospective multicenter investigation. Until December 1990, 2273 postmenopausal women (greater than 50 years) with first hip fractures were registered. Of these 643 sustained a hip fracture in 1988.

[Thoraco-scapular amputation in sarcomas of the shoulder girdle].

A total of 121 patients with sarcomas localized to the shoulder girdle were referred to the Sarcoma Centre in Arhus. Of these, 17 (14%) underwent interscapulothoracic amputation. At the time of treatment, the average age was 51 years (17-82 years).

Risk factors influencing mortality after bipolar hemiarthroplasty in the treatment of fracture of the femoral neck.

The hospital records of 204 patients (mean age 80 years, range 54-96 years) with a displaced intracapsular femoral neck fracture treated by cemented bipolar hemiarthroplasty were examined to record all available data on factors suspected of influencing mortality. The data were analyzed statistically using survival analysis (Cox model). The six months mortality rate was 20% and the one year mortality rate was 28%.
