This study aims to identify major factors that influence the decision to discontinue IVF treatment. METHODS Questionnaires were sent to 1510(More)
PRIMARY OBJECTIVE To investigate whether computer decision support software used in the management of patients with asthma improves clinical outcomes. RESEARCH DESIGN Randomized controlled trial with practices each reporting on 30 patients with asthma over a 6 month period. METHODS AND PROCEDURES 447 patients were randomly selected from practice asthma(More)
An infected axillary sinus tract discharged balls made of an acrylic resin consisting essentially of polymerized methyl methacrylate (Lucite) 45 years following performance of an extraperiosteal pneumonolysis and Lucite ball plombage for collapse therapy of right upper lobe cavitary tuberculosis. Surgical extraction of the balls was performed, followed by a(More)
BACKGROUND A study was undertaken to identify asthma patients at risk of an attack and to assess the economic impact of treatment strategies. METHODS A retrospective cohort analysis of a representative data set of 12 203 patients with asthma in the UK over a one year period was performed. Logistic multiple regression was used to model the probability of(More)
Methyl bromide (MeBr) is used as an insecticide fumigant. Four deaths and three recent hospitalizations have resulted from exposures to MeBr in Dade County, FL. Six cases occurred during burglaries of tented houses over a nine-month period. In four lethal exposures, the symptoms of nausea, vomiting, and malaise preceded fulminant respiratory failure. Two of(More)
Body mass index (BMI) relates weight to height and reflects the shape of a child, but because of age dependency it has not been used conventionally for the estimation of fatness in children. From measurements of Tayside children (n = 34,533) centile charts were constructed for BMI (wt/ht2) from the raw data of height and weight, using Cole's LMS method for(More)
Sudden unexplained death syndrome (SUDS) accounts for about 10% of deaths in patients with epilepsy. It is associated with subtherapeutic postmortem serum antiepileptic drug (AED) levels but no anatomic cause of death on autopsy. The mechanisms of death are not known. We investigated 44 cases of SUDS for details of seizure history, treatment, medical and(More)

Insulin resistance is a recognized feature of PCOS (polycystic ovary syndrome). However, the molecular reason(s) underlying this reduced cellular insulin sensitivity is not clear. The present study compares the major insulin signalling pathways in skeletal muscle isolated from PCOS and controls. We measured whole-body insulin sensitivity and insulin(More)
