The objectives of this study were to investigate the development and pathogenesis of osteoporosis in stroke in-patients, to compare the bone mineral density (BMD) of the paretic and non-paretic sides, to study longitudinal changes during the period on the rehabilitation ward and to relate BMD to demographic, impairment and disability variables. Participants were 32 first-stroke in-patients (19 men), with an average age of 62.4 +/- 8.1 years. Demographic and clinical characteristics were documented. The BMD of lumbar spine, bilateral distal radius and femoral neck were measured and compared at admission and discharge. The associations between bone loss and age, sex, time since stroke, Brunnstrom motor recovery scores and functional independence measure motor (mFIM) scores were assessed. The mean percentage differences in BMD between paretic and non-paretic arms at discharge were 12% (P < 0.001) and 3.5% (P < 0.05), respectively, and between paretic and non-paretic legs were 5% (P < 0.01) and 2% (P < 0.05), respectively. There was a statistically significant correlation between BMD loss and Brunnstrom stage (r = -0.41) and mFIM score at admission (r = -0.42). In conclusion, patients with hemiparesis due to stroke are at increased risk of developing osteoporosis on the paretic side. Higher motor impairment and functional dependency at admission increases the risk. New strategies are needed for stroke patients to prevent further decreases in BMD and reduce the risk of fractures.
The objectives of this study were to investigate the effects of Hylan G-F 20 (Synvisc; Genzyme Biosurgery, Ridgefield, New Jersey, USA) injections on clinical and biomechanical gait characteristics of patients with knee osteoarthritis. The design was a before-after trial, set in the gait laboratory of the rehabilitation unit of a university hospital. Twelve patients participated with an average age (+/-SD) of 63.2+/-4.4 years, and Kellgren and Lawrence grade II or III knee osteoarthritis. The main outcome measures were the Western Ontario McMaster Universities Osteoarthritis Index, and time-distance, kinematic and kinetic parameters of gait. The intervention used was a single course of three bilateral intra-articular injections of 2 ml Hylan G-F 20. One week after the treatment, the pain subscore and total score of WOMAC decreased from 9.2+/-2.7 to 4.8+/-3.1 and from 42.1+/-15.2 to 37.9+/-13.5, respectively. There was improvement in sagittal plane excursions of the knee (from 40.2+/-8.1 to 43.3+/-8.5), in extensor and adductor moments (from 0.26+/-0.2 to 0.14+/-0.1 and from 0.45+/-0.1 to 0.41+/-0.1, respectively), and in scaled vertical forces (from 85.8+/-4.5 to 88.4+/-5.4). All these differences were statistically significant. In conclusion, intra-articular Hylan G-F 20 injections not only decrease pain in patients with knee osteoarthritis, but can alter the natural history of the disease by decreasing excessive loads in the knees.
Study design: A case report. Objectives: To present and discuss some of the difficulties in the diagnosis of brucellar spondylitis. Setting: Ankara University, Ibni Sina Hospital, Turkey. Methods: We report a patient with paraplegia, misdiagnosed as having a malignancy or tuberculosis who actually suffered from brucellar spondylitis. Diagnosis was established by her history and a compatible clinical picture together with a standard tube agglutination (Wright test) titer of X1/160 of antibodies for brucellosis. The patient was treated with oral doxycycline, rifampicin, and ciprofloxacin combination. Results: At the end of the treatment, the blood Brucella Wright and anti-human globulin T titer levels decreased. Her lower limb weakness improved. She could walk, and climb stairs with the help of a cane. Urinary retention and fecal incontinence also resolved. Conclusion: Brucellosis is a systemic infection involving the musculoskeletal and nervous systems. Spondylitis frequently occurs in elderly patients. An early diagnosis of brucellar spondylitis can often be difficult. In endemic regions, as in the case of our country, brucellar spondylitis should always be considered in the differential diagnosis of older patients with back pain and constitutional symptoms. An early diagnosis will help to prevent the development of more severe complications such as spinal cord compression.
Reactive arthritis is a seronegative, HLA-B27-linked spondyloarthropathy which occurs as a result of a pathogen, often of gastrointestinal or genitourinary origin, and triggers a cell-mediated immune response. In this article, we present a 64-yearold male case who developed reactive arthritis with fever and asymmetric oligoarthritis following treatment with intravesical Bacillus Calmette-Guerin (BCG) for bladder carcinoma.
