Impacted corticocancellous allografts and cement for femoral revision of total hip arthroplasty using Lubinus and Charnley prostheses.

Femoral revision of total hip arthroplasty using impacted morcellized allografts and a cemented Lubinus SP-II prosthesis (Waldemar Link GmbH & Co, Hamburg, Germany) or Charnley standard prosthesis (De Puy, Leeds, UK) was performed in patients with loss of bone stock grade II-IV according to the Endoclinic classification from first to eighth revision. We report the results from 57 hips in 56 patients, with a median of 64 months' follow-up. Modified Merle d'Aubigné-Postel postoperative scores increased significantly from preoperative to postoperative values for the Lubinus group and for the Charnley group.

Impacted corticocancellous allografts and cement for revision of the femur component in total hip arthroplasty.

Revision of the femur component in total hip arthroplasty using impacted morcellized bone allografts and cemented Lubinus SP-II prosthesis or Charnley standard prosthesis was performed in patients with loss of bone stock grade II through IV according to the Endo-Klinik classification from 1st to 8th revision. We report the results from 57 hips in 56 patients, with a median of 64 months' follow-up. Modified Merle d'Aubigne-Postel postoperative scores increased significantly from preoperative to postoperative values for the Lubinus group and for the Charnley group.

Successful treatment of adults with severe Hantavirus pulmonary syndrome with extracorporeal membrane oxygenation.

Objective: To describe our experience with the use of extracorporeal membrane oxygenation (ECMO) as a rescue therapy in adult patients with severe cardiopulmonary failure from Hantavirus pulmonary syndrome.

Design: Case series.

Setting: Tertiary referral center.

Cardiopulmonary manifestations of hantavirus pulmonary syndrome.

Objective: To describe the clinical characteristics of a group of patients infected with the newly recognized hantavirus in the Southwestern United States.

Design: Case series.

Setting: Tertiary referral center.

Hantavirus pulmonary syndrome: clinical, diagnostic, and virologic aspects.

Hantavirus pulmonary syndrome is an acute pneumonitis with a high mortality rate that is caused by a newly recognized hantavirus. Four Corners virus (also known as Muerto Canyon virus and Sin Nombre virus) is enzootic among deer mice (Peromyscus maniculatus). Incidental transmission to humans can result in a disease characterized by rapidly progressive respiratory insufficiency, diffuse noncardiogenic pulmonary edema, vascular volume contraction with hemoconcentration, lactic acidosis, depressed cardiac output, and cardiac dysrhythmias preterminally.

Hyperoxic suppression of Fc-gamma receptor-mediated phagocytosis by isolated murine pulmonary macrophages.

Lower respiratory tract exposure to high oxygen (O2) concentrations is known to induce changes in pulmonary function through effects on several cell types located within the lung parenchyma, including pulmonary macrophages (PM). We studied the effects of hyperoxic exposure on phagocytosis via Fc-gamma receptors (FcR) on isolated murine PM. PM cultured in hyperoxic conditions exhibited little change in ingestion via FcR for up to 96 h, compared with significant increases in ingestion by PM cultured in 21% O2 over the same time period.

Manual therapy with steroid injections--a new approach to treatment of low back pain. A controlled multicenter trial with an evaluation by orthopedic surgeons.

Fifty-three acute or subacute patients with low back pain were given standardized but optimized activating conventional treatment by primary health care teams. Forty-eight patients received an experimental treatment that included specific manual treatment, such as manipulation and specific mobilization, muscle stretching, auto-traction, and cortisone injections. After 4 months, the experimental group had a less restricted range of movement in extension, less restricted side-bending to the right and to the left, less local pain caused by extension and side-bending to the right, less pain radiating to the right leg caused by side-bending to the left, and a less positive straight leg raising test (both sides) than the conventionally treated group.

The captopril renogram in percutaneous transluminal angioplasty of the renal arteries.

Technetium-99m DTPA renograms were performed before and after angioplasty in a 63-year-old man with bilateral renal artery stenosis (RAS), hypertension, and renal insufficiency. Decreased isotope uptake after captopril by the right kidney assisted in the selection of the right renal artery for angioplasty. Post-angioplasty improvement in both blood pressure control and renal function was accompanied by an absence of effect of captopril on the isotope uptake by the right kidney.

Loosening of the Charnley hip. Radiographic analysis of 102 revisions.

This retrospective study was based on 102 Charnley hip arthroplasties that underwent a revision operation. Radiographs of hips with loose prosthetic components were compared with those with firm components. Migration and tilting of the socket and subsidence and varus shift of the stem were associated with loosening.

Acromioplasty for impingement syndrome.

In 51 patients (27-67 years) with subacromial impingement syndrome, an acromioplasty according to Neer was performed. In 11 patients, acromioclavicular arthrosis was found, and in these patients the lateral end of the clavicle was resected as well. The patients have been followed for an average of 21 (6-42) months.
