Worldwide, different strategies are being applied for symptomatic chronic subdural hematoma (CSDH). The aim of this study was to evaluate the efficacy of two treatment strategies for symptomatic CSDH: initial dexamethasone (DXM) therapy versus primary surgery by burr hole craniostomy (BHC). We retrospectively collected data for 120 symptomatic CSDH patients in two neurotrauma centers between 2014 and 2016, each with their own treatment protocol. Sixty patients received primary BHC (center A), and another 60 initial DXM therapy (center B). Primary outcome was evaluated by dichotomized modified Rankin Scale (mRS) score (0-3 and 4-6) and Markwalder Grading Scale (MGS) score at 3 months. Secondary outcomes were additional interventions, CSDH recurrence, mortality, complications, and duration of hospital stay. Baseline characteristics were similar in both groups. At 3 months, a favorable mRS score (0-3) was observed in 70% and 76% of patients in cohort A and B, respectively (odds ratio [OR] 0.77, 95% CI 0.30-1.98; p = 0.59). A favorable MGS score (0-1) was observed in 96% of patients in both groups (OR 0.98, 95% CI 0.45-2.15; p = 0.95). CSDH recurrence was 12% in cohort A and 22% in cohort B (p = 0.15). Mortality was 10% in both cohorts. In cohort B, additional surgery was performed in 83% at a median of 6 days, and significantly more patients had complications (55% vs. 35%, p = 0.02), a prolonged hospitalization (10 vs. 5 days; p = 0.02), and one or more follow-up cranial CT's (85% vs. 48%; p

Item does not contain fulltext OBJECTIVES: To evaluate the effects of early lumbar disc surgery compared with prolonged conservative care for patients with sciatica over two years of follow-up. DESIGN: Randomised controlled trial. SETTING: Nine Dutch hospitals. PARTICIPANTS: 283 patients with 6-12 weeks of sciatica. INTERVENTIONS: Early surgery or an intended six months of continued conservative treatment, with delayed surgery if needed. MAIN OUTCOME MEASURES: Scores from Roland disability questionnaire for sciatica, visual analogue scale for leg pain, and Likert self rating scale of global perceived recovery. RESULTS: Of the 141 patients assigned to undergo early surgery, 125 (89%) underwent microdiscectomy. Of the 142 patients assigned to conservative treatment, 62 (44%) eventually required surgery, seven doing so in the second year of follow-up. There was no significant overall difference between treatment arms in disability scores during the first two years (P=0.25). Improvement in leg pain was faster for patients randomised to early surgery, with a significant difference between "areas under the curves" over two years (P=0.05). This short term benefit of early surgery was no longer significant by six months and continued to narrow between six months and 24 months. Patient satisfaction decreased slightly between one and two years for both groups. At two years 20% of all patients reported an unsatisfactory outcome. CONCLUSIONS: Early surgery achieved more rapid relief of sciatica than conservative care, but outcomes were similar by one year and these did not change during the second year. TRIAL REGISTRY: ISRCT No 26872154.

BACKGROUND AND PURPOSE: Although enlargement of the cerebral ventricles plays a central role in the diagnosis of normal pressure hydrocephalus (NPH), there are no reports on the use of volumetric assessment to distinguish between patients who respond to ventriculoperitoneal shunt surgery and those who do not. The purpose of this study is to explore the association between preoperative intracranial compartment volumes and postoperative improvement. METHODS: Twenty-six patients (17 men; mean age, 75 years [range, 54–87 years]) with a clinical or radiologic suspicion of NPH were included in the study. Gait, cognition, and bladder function were evaluated by clinical rating. MR imaging of the brain was acquired at 0.5T and 1.5T. Total intracranial volume, ventricular volume, brain volume, and pericerebral CSF volume were determined by volumetric assessment. Four imaging variables were determined: ventricular volume ratio, brain volume ratio, pericerebral CSF volume ratio, and the ratio of ventricular volume to pericerebral CSF volume. All patients underwent ventriculoperitoneal shunt surgery. RESULTS: Clinical follow-up was assessed 1 year after shunt surgery. No difference in the mean ventricular volume ratio, the mean brain volume ratio, the mean pericerebral CSF volume ratio, and the mean ratio between ventricular and pericerebral CSF volume was found between subjects who improved on gait or cognition or bladder function and those who did not. CONCLUSION: Volumetric assessment has no predictive value in differentiating between NPH patients who respond to ventriculoperitoneal shunt surgery and those who do not.
