Reasons of drop-out from rehabilitation in patients of Turkish and Moroccan origin with chronic low back pain in The Netherlands: a qualitative study.

Objective: To explore which factors led to drop-out in patients of Turkish and Moroccan origin with chronic non-specific low back pain who participated in a rehabilitation programme.

Subjects: Patients of Turkish or Moroccan origin with chronic non-specific low back pain (n = 23) from 2 rehabilitation centres and 4 rehabilitation departments of general hospitals in the Netherlands.

Methods: In-depth semi-structured interviews were conducted with patients of Turkish and Moroccan origin (n = 23), rehabilitation physicians (n = 8) and rehabilitation therapists (n = 2).

Incidence and sources of native and prosthetic joint infection: a community based prospective survey.

Objectives: To determine the incidence and sources of bacterial arthritis in the Amsterdam health district and the maximum percentage of cases that theoretically would be preventable.

Methods: Patients with bacterial arthritis diagnosed between 1 October 1990 and 1 October 1993 were prospectively reported to the study centre by all 12 hospitals serving the district. Data were gathered on previous health status, source of infection, and microorganisms involved.

The outcome of bacterial arthritis: a prospective community-based study.

Objective: To assess the outcome and adverse prognostic factors of bacterial arthritis (BA).

Methods: In a prospective community survey of BA, data were collected at the time of diagnosis and at a mean of 2 years later. A poor patient outcome was defined as death due to BA or severe overall functional deterioration.

Risk factors for septic arthritis in patients with joint disease. A prospective study.

Objective: To quantify potential risk factors for septic arthritis, in order to identify a basis for prevention.

Methods: The occurrence of potential risk factors for septic arthritis in patients with joint diseases attending a rheumatic disease clinic was prospectively monitored at 3-month intervals over a period of 3 years. Potential risk factors investigated were type of joint disease, comorbidity, medication, joint prosthesis, infections, and invasive procedures.

A high-molecular-weight (greater than 8.10(5)) non-collagenous glycoprotein is synthesized by bovine cartilage in vitro.

A high-molecular-weight (greater than 8.10(5)) glycoprotein was detected in [3H]glucosamine-labeled bovine cartilage. Extraction with varying amounts of guanidinium chloride showed that the molecule was not tightly bound to other matrix substances.
