Background It is unknown whether decompressive craniectomy improves clinical outcome for people with spontaneous severe deep intracerebral haemorrhage. The SWITCH trial aimed to assess whether decompressive craniectomy plus best medical treatment in these patients improves outcome at 6 months compared to best medical treatment alone. Methods In this multicentre, randomised, open-label, assessor-blinded trial conducted in 42 stroke centres in Austria, Belgium, Finland, France, Germany, the Netherlands, Spain, Sweden, and Switzerland, adults (18–75 years) with a severe intracerebral haemorrhage involving the basal ganglia or thalamus were randomly assigned to receive either decompressive craniectomy plus best medical treatment or best medical treatment alone. The primary outcome was a score of 5–6 on the modified Rankin Scale (mRS) at 180 days, analysed in the intention-to-treat population. This trial is registered with ClincalTrials.gov , NCT02258919 , and is completed. Findings SWITCH had to be stopped early due to lack of funding. Between Oct 6, 2014, and April 4, 2023, 201 individuals were randomly assigned and 197 gave delayed informed consent (96 decompressive craniectomy plus best medical treatment, 101 best medical treatment). 63 (32%) were women and 134 (68%) men, the median age was 61 years (IQR 51–68), and the median haematoma volume 57 mL (IQR 44–74). 42 (44%) of 95 participants assigned to decompressive craniectomy plus best medical treatment and 55 (58%) assigned to best medical treatment alone had an mRS of 5–6 at 180 days (adjusted risk ratio [aRR] 0·77, 95% CI 0·59 to 1·01, adjusted risk difference [aRD] −13%, 95% CI −26 to 0, p=0·057). In the per-protocol analysis, 36 (47%) of 77 participants in the decompressive craniectomy plus best medical treatment group and 44 (60%) of 73 in the best medical treatment alone group had an mRS of 5–6 (aRR 0·76, 95% CI 0·58 to 1·00, aRD −15%, 95% CI −28 to 0). Severe adverse events occurred in 42 (41%) of 103 participants receiving decompressive craniectomy plus best medical treatment and 41 (44%) of 94 receiving best medical treatment. Interpretation SWITCH provides weak evidence that decompressive craniectomy plus best medical treatment might be superior to best medical treatment alone in people with severe deep intracerebral haemorrhage. The results do not apply to intracerebral haemorrhage in other locations, and survival is associated with severe disability in both groups.

BACKGROUND AND OBJECTIVES: Intracranial infection in children is a rare but life-threatening condition that requires immediate neurosurgical care. The impact of the COVID-19 pandemic on incidence and outcome is unclear. METHODS: This study is a multicenter retrospective analysis of children who underwent neurosurgical treatment of intracranial infections (epidural abscess, subdural empyema, cerebral abscess, ventriculitis, and meningitis) between January 2014 and October 2024. Comparison of children with intracranial infections and neurosurgical intervention stratified by pre and postpandemic. RESULTS: The annual incidence of pediatric intracranial infections requiring neurosurgery increased significantly from 5.6 cases (95% CI: 4.0-7.5) prepandemic to 14.4 cases (95% CI: 11.2-18.0) postpandemic, with an incidence risk ratio (IRR) of 2.6 (95% CI: 1.8-3.8; P < .0001). Causative were the observed sinusitis-associated cases, with absolute numbers rising from 13 prepandemic to 31 postpandemic. The annual incidence increased from 1.81 cases (95% CI: 0.99-2.97) to 6.45 cases (95% CI: 4.44-9.00), yielding an IRR of 3.6 (95% CI: 1.9-7.1; P = .0001). For otitis-related cases, absolute counts surged from 6 to 19, accompanied by an incidence increase from 0.83 (95% CI: 0.33-1.69) to 3.95 (95% CI: 2.43-6.01), with an IRR of 4.7 (95% CI: 2.0-13.0; P = .0009). However, functional outcomes assessed by the pediatric modified Rankin Scale showed no statistically significant differences between pre- and postpandemic cohorts in the Wilcoxon-Mann-Whitney test, both at discharge (P = .388) and at 3-month follow-up (P = .927). CONCLUSION: Our study demonstrates a significant increase in the incidence of intracranial infections requiring neurosurgical treatment in children after the pandemic, with a 2.4-fold higher IRR compared with the prepandemic period. The postpandemic group had a significantly higher incidence of underlying complicated otitis and sinusitis.
