Bone mineral density (BMD) was assessed by dual-photon X-ray absorptiometry at the lumbar spine (L3, L4), the proximal femur and the femoral shaft, and by single-photon absorptiometry at the forearm in 53 patients with complete traumatic paraplegia of at least 1 year's duration and in age- and sex-matched healthy controls. The patients did (n = 38) or did not (n = 15) regularly perform passive weightbearing standing with the aid of a standing device. Compared with the controls, the BMD of paraplegic patients was preserved in the lumbar spine and was markedly decreased in the proximal femur (33%) and the femoral shaft (25%). When considering all patients performing standing, they had a better-preserved BMD at the femoral shaft (p = 0.009), but not at the proximal femur, than patients not performing standing. BMD at the lumbar spine (L3, L4) was marginally higher in the standing group (significant only for L3; p = 0.040). A subgroup of patients performing standing with use of long leg braces had a significantly higher BMD at the proximal femur than patients using a standing frame or a standing wheelchair (p = 0.030). The present results suggest that passive mechanical loading can have a beneficial effect on the preservation of bone mass in osteoporosis found in paraplegics.

From a questionnaire sent to 90 spinal cord injury (SCI) patients it is concluded that 58% of patients with a complete SCI above L2 suer from constipation, de®ned as two or fewer bowel movements per week, or the use of aids such as laxatives, manual evacuation or enemas. Tetraplegic patients had the highest prevalence of constipation, while patients with low paraplegia were less prone to constipation. The use of anticholinergic drugs was found to predispose to constipation. Preserved rectal sensation did not in¯uence the presence of constipation. Faecal incontinence was rare. Regular abdominal pain was present in one third of SCI patients and might be caused by an irritable bowel syndrome in 62% of these.

In order to plan services for long-term care of those with acquired brain injury (ABI), the prevalence of ABI was investigated by using a postal inquiry sent to a representative sample of general practitioners, of whom 121 cooperated and registered 186 cases. The corresponding estimated prevalence of adults with ABI-related disabilities is 183 per 100 000 population. The large majority remained at home without professional assistance. One in five had resumed education or regained full employment, but over half spent their day at home with no specific activity. The need for specific care at home was present in almost half of the patients. One-quarter had employment-related needs, and one in five had living needs for specialized accommodation or supported living. In conclusion, this study primarily revealed unfulfilled needs in the area of day services aiming at a maximal social and professional reintegration.

Paraplegic patients presenting with a subacute limitation of hip joint mobility were subjected to serial sonographic examinations. In four patients the initial sonographic study disclosed discontinuity with fluid collection in the psoas muscle, which was diagnostic of a traumatic muscle rupture. All four patients subsequently developed sonographic and radiographic evidence of heterotopic ossification_ Our findings confirm that ultrasono graphy is an easy and inexpensive screening method for the early diagnosis of heterotopic ossification. The sonographic results obtained in these four paraplegic patients are indicative of a possible traumatic origin of heterotopic ossification around the hip.

Study design: A retrospective study concerning urinary tract infections in spinal cord injury (SCI) patients. Objectives: To check whether the regular (1/week) urine cultures allow a more accurate treatment of urinary tract infections in SCI patients compared to empiric treatment. Setting: Ghent University Hospital, East-Flanders, Belgium. Methods: Group 1: 24 tetraplegic patients; group 2: 22 paraplegic patients; group 3: 28 other polytrauma patients as controls. These groups were chosen as catheterisation and other voiding methods differ according to the underlying pathology.Results: An average of four clinically significant episodes of bacteriuria were found for groups 1 and 2, while group 3 experienced very few urinary infections. The mean species turnover of the first two groups was 2. No statistically significant difference was found in antibiotic-resistance patterns of organisms isolated. Conclusion: Despite different catheterisation techniques in para-and tetraplegic patients, we conclude that: (1) the number of episodes of clinical significant nosocomial urinary infections is not different; (2) the mean species turnover is the same; (3) because of the species turnover, the value of regular urine cultures for 'documented' treatment of clinical relevant urinary infections seems to be limited. So urine culture could be performed less frequently or only when therapy becomes mandatory; (4) No oral antibiotic with superior activity was found: treatment is best started empirically (after sampling for urine culture) and adjusted to the resulting antibiotic sensitivity screening.
