CONTEXT Mediastinal nodal staging is recommended for patients with resectable non-small cell lung cancer (NSCLC). Surgical staging has limitations, which results in the performance of unnecessary thoracotomies. Current guidelines acknowledge minimally invasive endosonography followed by surgical staging (if no nodal metastases are found by endosonography)(More)
Cystic fibrosis (CF) is characterized by progressive and ultimately fatal pulmonary disease although there are notable variations in clinical features. This heterogeneity is thought to lie outside the cystic fibrosis transmembrane regulator (CFTR) gene locus and may stem from deficiencies in the antiproteinase screen that protects the lung from proteolytic(More)
OBJECTIVES To assess the effect on clinical outcome of managing paediatric and adult patients with cystic fibrosis at specialised cystic fibrosis centres. DESIGN Cross sectional study. SETTING Two adult cystic fibrosis centres in the United Kingdom. SUBJECTS Patients from an adult cystic fibrosis centre in Manchester were subdivided into those who had(More)
INTRODUCTION To determine the sensitivity and accuracy of endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) for clarification of the nature of fluorodeoxyglucose-positron emission tomography (FDG) positive hilar and/or mediastinal lymph nodes in patients with (suspected) lung cancer. METHODS All consecutive patients who had(More)
BACKGROUND Obtaining a tissue diagnosis of malignancy is challenging in patients with suspected lung cancer presenting with centrally located intrapulmonary masses. OBJECTIVE (1) To evaluate the yield of endobronchial ultrasound with real-time guided transbronchial needle aspiration (EBUS-TBNA) for diagnosing centrally located lesions after a(More)
We report a rare case of advanced, metastatic gastrointestinal stromal tumor (GIST) in a young female. Molecular analysis of the tumor revealed wild-type (WT) KIT and platelet derived growth factor receptor alpha (PDGFRA) gene status with no mutations characteristic of adult GIST. Despite this she had clinical benefit and evidence of radiological response(More)
Persistent infection with Pseudomonas aeruginosa and inflammatory mechanisms play an important role in cystic fibrosis (CF) lung disease. ANCA against BPI, a potent host defence protein with anti-bacterial and anti-endotoxin properties, have been described in CF. We have assessed the relationship of anti-BPI antibodies to pulmonary disease severity in 148(More)
For many years, intraoperative cholangiography during cholecystectomy to aid definition of the biliary anatomy and to detect choledocholithiasis has been advocated. Although radiation exposure in fluoroscopic procedures is a concern, few available data exist regarding the radiation exposure incurred during intraoperative cholangiography. This study aimed to(More)
Gastrointestinal stromal tumours (GISTs) are defined as a group of C-KIT positive mesenchymal tumours of the gastrointestinal tract. Although they may arise throughout the gut, the commonest sites are stomach and small intestine. Over 80% of metastases are to the liver and omentum. Targeted therapy (imatinib) can inhibit C-KIT and thereby aberrant tumoural(More)
Pancreatic masses may be solid or cystic, benign or malignant, and their characterization can often be difficult as there is considerable overlap in their imaging features. Multidetector computed tomography (MDCT) with multiplanar reconstructions offers improved resolution and optimum visualization of the peripancreatic vasculature, which has improved the(More)
