Review Meta Analysis
A systematic review and meta-analysis of antiepileptic prophylaxis in spontaneous intracerebral hemorrhage.
Frequency of clinical seizures may be as high as 16% in patients with spontaneous intracerebral hemorrhage (ICH). Current guidelines recommend against antiepileptic drug (AED) prophylaxis, but this recommendation is based on older trials, and the effect of newer AEDs is uncertain. The aim of this review was to study effects of AEDs on seizure occurrence and outcome in patients with spontaneous ICH. ⋯ This systematic review and meta-analysis including recent studies focusing on newer AEDs supports the 2015 guidelines regarding AED use in spontaneous ICH. There are some important caveats, including a possible confounding association between AED use and higher ICH score and the overall poor quality of the available data. A randomized clinical trial may be helpful.

Pain is a common occurrence in patients with cancer, which, in some cases, is not adequately controlled with medical analgesia. Thalamotomy is a treatment option in such circumstances, but synthesis of historical evidence and thalamic stratified data are lacking. We therefore sought to systematically review evidence supporting radiofrequency thalamotomy for intractable cancer pain. ⋯ Adverse events were typically transient. We conclude that radiofrequency thalamotomy for cancer pain is well tolerated and can produce significant relief from intractable cancer pain. No superiority of thalamic target could be determined.

Case Reports Meta Analysis
Optimal management of calvarial lymphoma: a meta-analysis.
Calvarial lymphoma is an exceedingly rare phenomenon; the clinical presentation and imaging pattern mimic many diseases of the central nervous system. Several treatment approaches have been undertaken with variable use of surgery plus adjuvant chemotherapy and radiation; an optimal treatment algorithm has yet to be defined. The aim of this study was to better characterize management strategies and patient outcomes. ⋯ In an analysis from 1976 to 2019, 62 patients with a median age of 60 were included. The most common presentations were subcutaneous scalp mass (89%), headaches (26%), and focal neurological deficits (21%). Osteolytic changes on computed tomography were seen in 69% of patients with extension into either the intracranial or extracranial space in 97% of cases. Surgical excision was performed in 41 patients with a remission rate of 85% and a recurrence rate of 5%, which did not vary significantly from patients treated nonsurgically (remission in 75%, P = 0.479; recurrence in 0%, P = 1.000) CONCLUSIONS: In patients presenting with a progressively enlarging scalp mass, calvarial lymphoma should be in the differential diagnosis, as it can be effectively managed with a biopsy followed by chemotherapy and radiation. The role for open surgery may be limited.

The best surgical treatment for adult Chiari malformation type 1 remains widely debated. ⋯ Posterior fossa decompression and duraplasty with arachnoid preservation is a beneficial technique to treat Chiari malformation type 1 and reduces the risk of complications, particularly cerebrospinal fluid-related complications and the rate of reoperation.
