Abstract

Introduction Endoscopic third ventriculostomy (ETV) is becoming an increasingly widespread treatment for hydrocephalus, but research is primarily based on paediatric populations. In 2009, Kulkarni et al created the ETV Success score to predict the outcome of ETV in children. The purpose of this study is to create a prognostic model to predict the success of ETV for adult patients with hydrocephalus. The ability to predict who will benefit from an ETV will allow better primary patient selection both for ETV and shunting. This would reduce additional second procedures due to primary treatment failure. A success score specific for adults could also be used as a communication tool to provide better information and guidance to patients. Methods and analysis The study will adhere to the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis reporting guidelines and conducted as a retrospective chart review of all patients≥18 years of age treated with ETV at the participating centres between 1 January 2010 and 31 December 2018. Data collection is conducted locally in a standardised database. Univariate analysis will be used to identify several strong predictors to be included in a multivariate logistic regression model. The model will be validated using K-fold cross validation. Discrimination will be assessed using area under the receiver operating characteristic curve (AUROC) and calibration with calibration belt plots. Ethics and dissemination The study is approved by appropriate ethics or patient safety boards in all participating countries. Trial registration number NCT04773938; Pre-results.

Abstract

The article presents a case study of a 33-year-old male patient with chronic low back pain (CLBP). Topics discussed include the possible link between the reported CLBP and the previous lumbar discectomy of the patient, the Pfirrmann grade IV disc degeneration observed from the magnetic resonance imaging (MRI) performed, and the intradiscal injection of platelet-rich plasma to treat the condition.

Abstract

Objective: The authors set out to study whether autosomal dominant polycystic kidney disease (ADPKD), an established risk factor for intracranial aneurysms (IAs), affects the acute course and long-term outcome of aneurysmal subarachnoid hemorrhage (aSAH)., Methods: The outcomes of 32 ADPKD patients with aSAH between 1980 and 2015 (median age 43 years; 50% women) were compared with 160 matched (age, sex, and year of aSAH) non-ADPKD aSAH patients in the prospectively collected Kuopio Intracranial Aneurysm Patient and Family Database., Results: At 12 months, 75% of the aSAH patients with ADPKD versus 71% of the matched-control aSAH patients without ADPKD had good outcomes (Glasgow Outcome Scale score 4 or 5). There was no significant difference in condition at admission. Hypertension had been diagnosed before aSAH in 69% of the ADPKD patients versus 27% of controls (p < 0.001). Multiple IAs were present in 44% of patients in the ADPKD group versus 25% in the control group (p = 0.03). The most common sites of ruptured IAs were the anterior communicating artery (47% vs 29%, p = 0.05) and the middle cerebral artery bifurcation (28% vs 31%), and the median size was 6.0 mm versus 8.0 mm (p = 0.02). During the median follow-up of 11 years, a second aSAH occurred in 3 of 29 (10%) ADPKD patients and in 4 of 131 (3%) controls (p = 0.11). A fatal second aSAH due to a confirmed de novo aneurysm occurred in 2 (6%) of the ADPKD patients but in none of the controls (p = 0.027)., Conclusions: The outcomes of ADPKD patients with aSAH did not differ significantly from those of matched non-ADPKD aSAH patients. ADPKD patients had an increased risk of second aSAH from a de novo aneurysm, warranting long-term angiographic follow-up.

Abstract

Background: The purpose of this population-based case-control study was to evaluate analgesic use after subarachnoid hemorrhage (SAH) caused by rupture of a saccular intracranial aneurysm (sIA)., Methods: The study consisted of 1187 patients alive 12 months after an sIA-SAH who were admitted to Kuopio University Hospital (KUH) between 1995 and 2014. Three controls, matched with age, sex, and birthplace, were included for each patient. Data on ruptured sIA cases admitted to KUH from a defined catchment population in Eastern Finland were obtained from the KUH intracranial aneurysm database. Analgesics were classified according to the Anatomical Therapeutic Chemical Classification system. Data on analgesic medication were retrieved from the Finnish national registry of prescribed medicines of the Social Insurance Institution of Finland., Results: Among 1187 patients with sIA-SAH who were alive 12 months after admission, 83 (7.0%) commenced analgesics use within 12 months after the sIA-SAH versus 53 (1.5%) of the 3561 population controls. The results revealed significantly greater initiation rate of analgesic use among patients with sIA-SAH within a year after sIA-SAH as compared with that of matched population controls (odds ratio 5.0; 95% confidence interval 3.5-7.0; P < 0.001). Analgesic use commencement within 12 months of an sIA-SAH was independently associated with the presence of an intracerebral hematoma. Among patients, commencing analgesic use increased 11% when we compared a year before and a year after sIA-SAH., Conclusions: Our results indicate that patients with sIA-SAH had an increased risk for new pain after sIA-SAH as compared with that of matched control population., (Copyright © 2019 Elsevier Inc.
