Luxatio erecta--two cases without direct injury.

Two cases of erect dislocation of the shoulder occurring during racket sports without associated falls or direct violence to the shoulder are reported. Both were mistaken for anterior dislocations and in one, with unrecognized brachial plexus injury, reduction was delayed with subsequent prolonged and incomplete neurological recovery. Erect dislocation should be recognized as a separate entity with a high incidence of neurological damage and requiring a different method of reduction.

The significance of peak expiratory flow rate in assessing prognosis of elderly patients undergoing operations on the hip.

Peak expiratory flow rate (PEFR) was measured using a Wright peak flow meter in 190 patients with fracture of the proximal part of the femur, and in 110 patients who underwent elective total hip replacement. PEFR was significantly lower in the fracture group than in the elective group when similar age ranges were compared. In the fracture group, PEFR of less than 100 was associated with a 69.6 per cent mortality rate, whereas no deaths occurred where the PEFR was greater than 300. It is suggested that the patients' PEFR is a good indicator of their prospects and it can be easily measured on admission.

New technology and economic incentives will spur the growth of dialysis at home.

Prospective reimbursement was HCFA's attempt to rein in the spiralling cost of the ESRD program. Its implementation would press far-ranging changes upon the operations of providers. As a supplier to the dialysis community. Travenol would also have to adapt if the implications desired by HCFA were likely to come to pass. It was crucial to our planning to assess and understand the implications of the new regulations. We examined two key assumptions in HCFA's design: whether home care was a feasible alternative to in-center care, and whether the costs at home were lower than in-center. CAPD, a relatively new home dialysis procedure, would be the likely target to absorb the bulk of the potential shift in patient referrals. Not an option for everyone, CAPD was limited by medical contraindications (e.g. diverticulitis) and by the requirements of self care. Yet the number of patients on CAPD had grown dramatically from its development in the late 1970s. Worldwide, the number of patients had grown to over 20,000. Despite its apparent success, many nephrologists remained skeptical that CAPD offered care comparable to in-center hemodialysis. Upon examination, it appeared that this controversy was fading as more and more evidence came to light suggesting equivalency. A shift in referral patterns looked feasible. To spur the shift, HCFA attempted to design economic incentives into the reimbursement system. The incentives relied on the costs of home dialysis being lower than those in-center--a fact thrown into question when HCFA's cost database was deemed of doubtful accuracy.(ABSTRACT TRUNCATED AT 250 WORDS)

Regional anaesthesia in elective hand surgery.

The technique of regional anaesthesia for hand surgery is described. This has been successfully carried out in a series of 179 patients treated as day cases. The advantages and disadvantages of the technique are discussed. Emphasis is placed on careful patient selection and attention to detail in applying the technique.
