Total hip arthroplasty with cement and without acetabular bone graft for severe hip dysplasia. A concise follow-up, at a minimum of twenty years, of a previous report.

We previously evaluated a cohort of fifty-three patients with severe hip dysplasia (Crowe Type-II, III, or IV subluxation) who underwent a total of sixty-six Charnley total hip arthroplasties. The acetabular component was placed at the anatomic hip center, the superolateral defect was filled with cement, and no bone-grafting was used to supplement the acetabular wall. All but one patient, who was lost to follow-up, were followed until death or for a minimum of twenty years.

4.5-gram monofilament sensation beneath both first metatarsal heads indicates protective foot sensation in diabetic patients.

Background: Loss of protective plantar foot sensation is the major cause of diabetic foot ulcerations and ultimate limb loss. Identification of patients without protective sensation can reduce the risk of unrecognized foot injury. The current recommended screening protocol requires 10-g monofilament testing of ten foot sites with use of a forced-choice paradigm.

Charnley total hip arthroplasty with use of improved cementing techniques: a minimum twenty-year follow-up study.

Background: In total hip arthroplasty, techniques for cementing the femoral component have changed over time. The purpose of the present study was to determine whether a cementing technique that includes use of a distal cement plug and retrograde filling of the femoral canal affects the fixation of the femoral component at a minimum of twenty years after the operation.

Methods: Between 1976 and 1978, the senior one of us (R.

The sea pansy Renilla reniformis luciferase serves as a sensitive bioluminescent reporter for differential gene expression in Candida albicans.

The infectious yeast Candida albicans progresses through two developmental programs which involve differential gene expression, the bud-hypha transition and high-frequency phenotypic switching. To understand how differentially expressed genes are regulated in this organism, the promoters of phase-specific genes must be functionally characterized, and a bioluminescent reporter system would facilitate such characterization. However, C.
