Brain biopsy in cryptogenic neurological disease.

Objective: Brain biopsy is standard clinical practice when CNS malignancy is suspected. Its value has not otherwise been clearly established. We reviewed the indications for, complications and outcome of diagnostic brain biopsies performed between 2003 and 2008 in a single UK centre.

Surveillance of primary antibiotic resistance of Helicobacter pylori at centres in England and Wales over a six-year period (2000-2005).

Antibiotic resistance is a key factor in the failure of Helicobacter pylori eradication therapy, yet few sentinel schemes exist to monitor trends in resistance at local, national or international levels. This study aimed, over a six-year period, to monitor resistance levels of H. pylori in England and Wales to the four antibiotics used in its treatment.

Eradication of methicillin resistant Staphylococcus aureus by "ring fencing" of elective orthopaedic beds.

Problem: Deep infection after joint arthroplasty can be catastrophic, leading to further surgery, loss of the prosthesis, disability, and risk of mortality. Twenty nine new cases of methicillin resistant Staphylococcus aureus occurred in the first year after elective orthopaedic surgery was centralised to a district general hospital in Essex.

Design: Prospective trial to establish whether ring fencing of elective orthopaedic beds and introduction of simple infection control measures has an effect on the rates of postoperative infections and number of patients treated.

Non-invasive diagnosis of Helicobacter pylori infection in adult dyspeptic patients by stool antigen detection: does the rapid immunochromatography test provide a reliable alternative to conventional ELISA kits?

Stool antigen-testing allows non-invasive detection of Helicobacter pylori that is indicative of active infection. Three commercial kits are currently marketed in the UK for stool antigen-testing. The aim of this study was to conduct a comparative evaluation of the performances of each of these tests, compared with culture and histological examination of gastric biopsies, for pre-treatment diagnosis of infection in an adult dyspeptic population in south-east England.
