Comparative StudyComparative effectiveness of antibiotic-impregnated shunt catheters in the treatment of adult and pediatric hydrocephalus: analysis of 12,589 consecutive cases from 287 US hospital systems.
The real-world effectiveness of antibiotic-impregnated shunt catheters to reduce the incidence of shunt infections is still debated. The literature to date consists mostly of small, single-institution studies. The aim of this study was to assess the incidence of infection for antibiotic-impregnated catheters (AICs) versus standard shunt catheters in a large nationwide administrative database. ⋯ The use of antibiotic-impregnated shunt catheters was associated with a reduction in shunt infections for both adult and pediatric patients. This provides further support that AICs may represent a reliable means of reducing shunt infections for both adult and pediatric patients.

Case ReportsFrameless robotic stereotactic biopsies: a consecutive series of 100 cases.
Stereotactic biopsy procedures are an everyday part of neurosurgery. The procedure provides an accurate histological diagnosis with the least possible morbidity. Robotic stereotactic biopsy needs to be an accurate, safe, frameless, and rapid technique. This article reports the clinical results of a series of 100 frameless robotic biopsies using a Medtech ROSA device. ⋯ ROSA frameless stereotactic biopsies appear to be accurate and safe robotized frameless procedures.

Historical ArticleFixed and dilated: the history of a classic pupil abnormality.
The aim of this study was to investigate the development of ideas about the nature and mechanism of the fixed dilated pupil, paying particular attention to experimental conditions and clinical observations in the 19th century. Starting from Kocher's standard review in 1901, the authors studied German, English, and French texts for historical information. Medical and neurological textbooks from the 19th and 20th centuries were reviewed to investigate when and how this information percolated through neurological and neurosurgical practices. ⋯ The key observation of a fixed dilated pupil as a sign of acute mass effect came gradually and after some localization stumbles. Following the period of extensive experimental research in ICP, the results of which were translated to clinical observations, the prognostic significance was gradually acknowledged by authors of neurological textbooks. It is well known that Cushing did similar experiments in Berne (1900-1901), and later suggested he would not have done so if he had studied the literature.
