METHODS: A retrospective case note analysis was undertaken in consecutive patients undergoing brain biopsy at The Walton Centre for Neurology and Neurosurgery during a 15-year period. The diagnostic yield, prebiopsy diagnostic category, biopsy technique (open versus stereotactic), complication rates, and impact on clinical management were assessed. Biopsies were grouped into one of five categories:
diagnostic, suggestive, nonspecific, normal, or nondiagnostic.
RESULTS: Thirty-nine patients underwent biopsy. The diagnostic yield (combined diagnostic and suggestive) of targeted serial stereotactic biopsy was 64% (seven of 11 patients); in the open brain biopsy group, the diagnostic yield was 46% (13 of 28 patients). The prebiopsy diagnosis was confirmed in 100% (three of three patients) stereotactic biopsy patients and 75% (nine of 12 patients) https://www.selleckchem.com/products/px-478-2hcl.html of open biopsy patients. Two patients (7%) in the open biopsy group had short-term complications. The clinical impact
was similar in both groups: nine of 28 (32%) open biopsy patients and four of 11 (36%) stereotactic biopsy patients.
CONCLUSION: Despite the low clinical impact, diagnostic brain biopsy should be considered in patients with nonneoplastic undiagnosed neurological disorders. Patients with neuroimaging abnormalities should preferentially undergo targeted biopsy.”
“The biological characteristics of BoHV-4 make it a good candidate as a gene Idasanutlin order delivery vector for vaccination purposes. These characteristics include little or no pathogenicity, unlikely oncogenicity, the ability to accommodate large amounts of foreign genetic material, the ability to infect several cell types from different animal species, such as sheep, goats, swine, cats, dogs, rabbits, mink, horses, turkeys, ferrets, monkeys,
hamsters, rats, mice, and chickens. In this report, the feasibility to use BoHV-4 based vector in chicken was investigated. Although BoHV-4 Autophagy inhibitor was able to replicate, leading to a cytopathic effect in a chicken cell line and infect the chorion allantoic membrane of embryonated eggs, however it was not pathogenic even when a large dose of virus was injected into the chicken. An immune response could be produced against heterologous antigen delivered by a recombinant BoHV-4. These data suggest the feasibility of using BoHV-4 based vector for vaccination purposes in chickens. (C) 2008 Elsevier B.V. All rights reserved.”
“OBJECTIVE: The aim of this study was to evaluate the effect of early optic canal unroofing on visual function in patients with meningiomas of the tuberculum sellae and planum sphenoidale.
METHODS: We retrospectively reviewed the clinical records of 20 consecutive patients with tuberculum sellae meningiomas and two patients with planum sphenoidale meningiomas who were admitted to our institution from 1999 to 2007.
