This prospective, randomised controlled trial, with three parallel groups, patient and observer blinded for verum and sham acupuncture and a follow up of 3 months raises the question: "Does a combination of acupuncture and conservative orthopedic treatment improve conservative orthopedic treatment in chronic low back pain (LBP). 186 in-patients of a LBP rehabilitation center with a history of LBP >or=6 weeks, VAS >or=50mm, and no pending compensation claims, were selected; for the three random group 4 weeks of treatment was applied. 174 patients met the protocol criteria and reported after treatment, 124 reported after 3 months follow up. Patients were assorted 4 strata: chronic LBP, or=5 years. Analysis was by intention to treat. Group 1 (Verum+COT) received 12 treatments of verum acupuncture and conservative orthopedic treatment (COT). Group 2 (Sham+COT) received 12 treatments of non-specific needling and COT. Group 3 (nil+COT) received COT alone. Verum- and Sham acupuncture were blinded against patient and examiner. The primary endpoints were pain reduction >or=50% on VAS 3 months after the end of the treatment protocol. Secondary endpoints were pain reduction >or=50% on VAS and treatment efficacy on a four-point box scale directly after the end of the treatment protocol and treatment efficacy after 3 months. In the whole sample a pain relief of >or=50% on VAS was reported directly after the end of treatment protocol: Verum+COT 65% (95%CI 51-77%), Sham+COT 34% (95%ci 22-49%), nil+COT 43% (95%ci 29-58%) - results are significant for Verum+COT over Sham+COT (P

Background and Purpose-Most patients have elevated blood pressure (BP) in the early phase after an acute ischemic stroke. Mechanism and effects of this BP elevation are not well understood. The benefits of intervention by lowering the initial BP or waiting for spontaneous return to normal values remain debated. We studied the hypothesis that increased BP level and profile variability will adversely affect long-term outcome after stroke with and without thrombolytic treatment. Methods-We studied the 615 patients with acute ischemic hemispheric stroke in the first European Cooperative Acute Stroke Study (ECASS). BP was measured at 2-hour intervals during the first 20 hours after randomization, and then every 4 hours, up to 72 hours after admission.

The prognostic relevance of minimal residual disease (MRD) in patients with multiple myeloma is still an open question. We measured MRD levels in bone marrow (BM) samples of 53 patients treated with high-dose therapy (HDT) and autologous peripheral blood stem cell transplantation using real-time quantitative (RQ)-IgH-PCR with allel-specific oligonucleotide probes. We identified a prognostically relevant threshold level of 0.2% 2IgH/β-actin ratio in the BM before HDT. Twenty-six patients with MRD levels below this value were termed as the "low-MRD group," whereas 27 patients with levels above this threshold were allocated to the "high-MRD group." Median event-free-survival (EFS) in the low-MRD group was significantly (P = .001) longer than in the high-MRD group with 35 versus 20 months, respectively. Overall survival (OS) within the low-MRD group was also significantly longer with 70 versus 45 months (P = .04). Using multivariate analysis, we found that the pretransplantation MRD level was an independent prognostic factor for EFS (P = .003) and OS (P = .05). Further, EFS of patients in the high-MRD could be improved (P = .005) when they achieved a low MRD level after HDT. In conclusion, measuring MRD is of prognostic relevance in patients with MM, and low MRD levels should be a goal of treatment.

Predictors for the degree of clinical recovery after stroke are still poorly defined. In this study we tried to assess the predictive value of clinical data and of lesion size for motor recovery after ischemic stroke. In 52 hemiparetic patients we monitored the course of clinical recovery by a dedicated score of sensorimotor hand function after their first stroke. The course of the lesion size was measured in proton density magnetic resonance images. Three groups of patients were identified. Patients with moderate initial motor deficit recovered almost completely within 9 days (17/17, group 1). From the patients with severe initial motor deficit, about equal numbers recovered (16/35, group 2) or remained severely impaired during the entire observation period of more than 6 months (19/35, group 3). There was no correlation between changes of lesion size and motor deficit. Logistic regression of probability of good clinical outcome on initial lesion size, initial motor score and subcortical versus cortical location of lesion showed that only the initial motor score was predictive (p = 0.006). A relative improvement of the initial motor score of about 20% in the first 4 weeks after stroke appeared to be a relevant cut point for good outcome. The data indicate that patients with mild initial motor deficits recover well, whereas severely affected patients may differ in outcome. Since lesion size was not correlated with outcome the amount of spared residual function appeared as major determinant for the capacity for motor recovery.
