Interdisciplinary Infection Prevention and Control Bundle in Neurosurgical Patients: Results of a Prospective Cohort Study.
Surgical site infections (SSIs) account for one of the most common causes of nosocomial infections. Bundle approaches for infection prevention and control do not capture the full complexity of neurosurgical interventions. ⋯ Introducing an interdisciplinary IPCB in neurosurgery leads to a significant reduction of sepsis and decreased in-hospital mortality while a pathogen switch toward gram-negative bacteria was observed. Minimizing diagnostic gap of pathogen detection toward a more efficient anti-infective treatment may be the main reason for the substantial decrease in morbidity and mortality.

Histopathological features and molecular biomarkers have been studied as potential prognostic factors. This study aimed to investigate the clinical features, molecular phenotypes, and survival prognosis of isocitrate dehydrogenase (IDH)-mutant (IDHmt) gliomas with histone H3 alterations (H3-alterations). ⋯ Identification and assessment of histone H3 status in clinical practice might help improve prognostic prediction and develop therapeutic strategies for these patient subgroups.

Transpedicular or transisthmic screws for C2 instrumentation represent the gold standard; however, the anatomy is not always compatible (hypoplastic pedicles, procidentia of the vertebral artery). Laminar screws (LS) have been proposed as a rescue technique and recently, bicortical facet screws (FS). To date, the biomechanical property of FS remains unknown. ⋯ Our results suggest that bicortical FS of C2 offer less mechanical resistance than LS.

The microlesion effect refers to the improvement of clinical symptoms after deep brain stimulation (DBS) lead placement and is suggested to indicate optimal lead placement. Very few studies have reported its implications in neuropsychiatric disorders. ⋯ This study shows that the microlesion effect may seem as an immediate improvement after optimal DBS lead placement in patients with Tourette syndrome.

Trigeminal autonomic cephalalgias (TACs) are a group of highly disabling primary headache disorders. Although pharmacological treatments exist, they are not always effective or well tolerated. Occipital nerve stimulation (ONS) is a potentially effective surgical treatment. ⋯ ONS may be an effective surgical treatment for approximately two thirds of patients with medically refractory TACs.
