- Objective and designThe prevalence of low back pain was assessed in relation to physical activity, for both work and leisure activities, in a randomly selected population in the northern part of Sweden. Additionally, the associations between age, sex, level of education, lifestyle factors, demographic characteristics, and low back pain were evaluated. Subjects: A total of 5798 subjects aged 25–79 years were selected randomly from a geographically well-defined area in northern Sweden. Methods: Additional questions concerning people's experience of low back pain were added to the questionnaire of the World Health Organization MONICA (MONItoring of trends and determinants in CArdiovascular disease) health survey with the aim of investigating prevalence rates and factors associated with low back pain. Results: Forty-one percent of the participants reported having low back pain (of these 55% were women and 45% men). The prevalence rate was highest in the age group 55–64 years. Chronic low back pain was the most frequent occurring problem. Of those with low back pain, 43% of the women and 37% of the men reported having continuous low back pain for more than 6 months. Individuals with low back pain often experienced a more physically heavy workload at work and lower physical activity during leisure time, and they were also more likely to have been smokers, have had higher body mass index, lived in smaller communities, and were less educated than people without low back pain. Conclusion: Low back pain seems to be associated with physical activity at work and in leisure time, certain lifestyle factors and demographic characteristics.

- Background. Spinal cord compression is an oncological and surgical emergency. Delays in referral and diagnosis may influence functional outcome. It is therefore important to identify patients who will regain or maintain ability to walk after surgery. The aim of the present study was to examine current practice for referral and diagnosis of prostate cancer patients with spinal cord compression and to identify prognostic factors for neurological outcome after surgery.Patients and methods. The study includes 68 consecutive patients with prostate cancer who underwent surgery due to neurological compromise. Intervals from onset of neurological symptoms to referral, diagnosis, and treatment were analyzed in relation to functional outcome. The prognostic significance of preoperative clinical parameters on gait function one month after surgery was evaluated.Results. Patients who were referred from local hospitals had longer delay to surgery than those who directly presented to the cancer centre (p=0.004). The rate of diagnosis with MRI increased through the week and peaked on Friday, with few patients being diagnosed during weekends. Ability to walk before surgery, hormone-naive prostate cancer, and/or shorter time from loss of ambulation were associated with more favorable neurological outcome. In patients with hormone-refractory disease who were unable to walk before surgery regaining of ambulation was associated with: duration of paresis <48 hours (p=0.005), good preoperative performance status (p=0.04), preoperative PSA serum level <200 ng/ml (p=0.03), and surgery with posterior decompression and stabilization (p=0.03).Conclusion. Early diagnosis and rapid treatment of spinal cord compression in prostate cancer patients is crucial for neurological recovery. Rising of awareness for the condition among patients at risk and among physicians is mandatory as well as improvement of local and regional guidelines for treatment.

- Background and purpose The criteria for selecting patients who may benefit from surgery of spinal cord compression in metastatic prostate cancer are poorly defined. We therefore studied patients operated for metastatic spinal cord compression in order to evaluate outcome of surgery and to find predictors of survival. Patients and methods We reviewed the records of 54 consecutive patients with metastatic prostate cancer who were operated for spinal cord compression at Umeå University Hospital. The indication for surgery was neurological deficit due to spinal cord compression. 41 patients had hormone-refractory cancer and 13 patients had previously untreated, hormone-naïve prostate cancer. 29 patients were operated with posterior decompression only, and in 25 patients posterior decompression and stabilization was performed. Results Preoperatively, 6/54 of patients were able to walk. 1 month after surgery, 33 patients were walking, 15 were non-ambulatory, and 6 had died. Mortality rate was 11% at 1 month, 41% at 6 months, and 59% at 1 year. In the hormone-naïve group, 8/13 patients were still alive with a median postoperative follow-up of 26 months. In the hormone-refractory group, median survival was 5 months. Patients with hormone-refractory disease and Karnofsky performance status (KPS) of ≤ 60% had median survival of 2.5 months, whereas those with KPS of 70% and KPS of ≥ 80% had a median survival of 7 months and 18 months, respectively (p < 0.001). Visceral metastases were present in 12/41 patients with hormone-refractory tumor at the time of spinal surgery, and their median survival was 4 months-as compared to 10 months in patients without visceral metastases (p = 0.003). Complications within 30 days of surgery occurred in 19/54 patients. Interpretation Our results indicate that patients with hormone-naive disease, and those with hormone-refractory disease with good performance status and lacking visceral metastases, may be helped by surgery for metastatic spinal cord compression.

- Study design. We retrospectively analyzed prognostic factors for survival in prostate cancer patients operated for metastatic spinal cord compression.Objective. The aim was to obtain a clinical score for prediction of survival after surgery.Summary of background data. Survival prognosis is important when deciding about treatment of patients with metastatic spinal cord compression. The criteria for identifying prostate cancer patients who may benefit from surgical treatment are unclear.Patients and methods The study comprised 68 consecutive patients with prostate cancer operated for metastatic spinal cord compression at Umeå University Hospital, Sweden. The indication for surgery was neurological deficit; 53 patients had hormone-refractory prostate cancer, and 15 patients had previously untreated, hormone-naïve prostate cancer. In 42 patients posterior decompression was performed and 26 patients were operated with posterior decompression and stabilization.Results A new score for prediction of survival was developed based on the results of survival analyses. The score includes: hormone status of prostate cancer, Karnofsky performance status, evidence of visceral metastasis, and preoperative serum PSA. The total scores ranged from 0 to 6. Three prognostic groups were formulated: group A (n = 32) with scores 0-1; group B (n = 23) with scores 2-4, and group C (n = 12) with scores 5-6. The median overall survival was 3 (0.3 - 20) months in group A, 16 (1.8 - 59) months in group B, and in group C more than half (7 of 12) of patients were still alive.Conclusion We present a new prognostic score for predicting survival of prostate cancer patients after surgery for metastatic spinal cord compression. The score is easy to apply in clinical practice and may be used as additional support when making decision about treatment.

- The two northernmost counties in Sweden form together 1 of the 39 collaborating centers in the World Health Organization (WHO) MONICA (MONItoring of trends and determinants in CArdiovascular disease) project. At the last survey in 1999, we added some questions about cervical spine complaints. Persons randomly selected from the population in a geographically well-defined area completed a self-administered questionnaire. The sample included 8,356 subjects and 6,000 (72%) of them answered. 43% of the population reported neck pain, more women (48%) than men (38%). Women of working age had more neck pain than older ones, a phenomenon not seen among men. Chronic neck pain, defined as continuous pain of more than 6 months' duration, was commoner in women (22%) than men (16%).More than one fourth of the cases with chronic symptoms had a history of neck or head trauma and one third of these had sustained a whiplash type of injury. Thus, all types of neck trauma seem to be associated with chronic neck pain.

- Twenty-six consecutive patients (19 men and 7 women) with a mean age of 31.5 years (range 19-52 years) who suffered from an isolated full-thickness cartilage defect of the patella (area ranged from 0.75 to 20.0 cm2) and disabling knee pain were treated with autologous periosteal transplantation (without any chondrocytes). The duration of symptoms was 59 months (range 11-144 months). During the first 5 postoperative days all patients were treated with continuous passive motion (CPM). This was followed by active motion, slowly progressive strength training, and slowly progressive weight-bearing. After a mean follow-up of 42 months (range 24-76 months), 17 patients (65%) were graded as excellent (were painfree), 8 patients (31%) as good (had pain with strenuous knee-loading activities), and 1 patient as poor (had pain at rest). Twenty-two patients (85%) had returned to their previous occupation. Twelve patients (46%) had resumed sports or recreational activities at their former level. Repeated magnetic resonance imaging (MRI) investigations showed progressive, and finally complete, filling of the articular defects. Biopsies taken in five randomly selected cases showed hyaline-like cartilage. Patients with full-thickness cartilage defects of the patella and disabling knee pain can be treated with autologous periosteal transplantation (without any chondrocytes), followed by CPM, and slowly progressive strength training and weight-bearing. We believe this is a good method to accomplish regeneration of articular cartilage and satisfactory clinical results.
