Leukoplakia is an asymptomatic, potentially malignant change in the oral mucosa. Previous studies have reported that smoking and betel quid chewing are associated with increased risk of leukoplakia; few studies have reported on these associations in populations where betel quid does not contain tobacco. We conducted a case-control study nested in a(More)
BACKGROUND Several studies have investigated the impact of mobile phone exposure on cognitive function in adults. However, children and adolescents are of special interest due to their developing nervous systems. METHODS Data were derived from the Australian Mobile Radiofrequency Phone Exposed Users' Study (MoRPhEUS) which comprised a baseline examination(More)
Smoking and betel quid chewing are associated with increased risk of oral cancer but few studies have reported on associations in populations where betel quid does not contain tobacco. We conducted a case-control study in Papua New Guinea and a systematic review. Our case-control study recruited 143 cases with oral cancer and 477 controls. We collected(More)
BACKGROUND Ileus commonly occurs after abdominal surgery, and is associated with complications and increased length of hospital stay (LOHS). Onset of ileus is considered to be multifactorial, and a variety of preventative methods have been investigated. Chewing gum (CG) is hypothesised to reduce postoperative ileus by stimulating early recovery of(More)
OBJECTIVE To determine the effects of the anabolic agent oxandrolone on muscle protein and gene expression in severely burned children. SUMMARY BACKGROUND DATA The authors previously showed that oxandrolone increased net muscle protein synthesis in emaciated burned patients receiving delayed treatment for severe burns. They hypothesized that similar(More)
BACKGROUND Severe burn induces the hepatic acute phase response. In this study, we wondered whether continuous insulin treatment decreases acute phase protein levels in the severely burned. METHODS Eighteen children aged 2 to 17 years with burns >40% of total body surface area were randomized to receive either insulin (n=9) or no treatment (n=9) within 72(More)
The management of orbital blowout fractures is controversial. The continuing debate includes the use of antibiotics and steroids, imaging, the surgical approach, and the choice of implant material for repair of the bony defect.A cross-sectional study was undertaken to assess current practice in treating orbital blowout fractures in the UK, in the form of a(More)
Ethnic disparities in patterns of utilization and outcomes after Roux-en-Y gastric bypass surgery (RYGB) were examined from Bariatric Outcomes Longitudinal Database. Descriptive statistics were used for demographics of Whites, Blacks, or Hispanics undergoing RYGB with 1 year of follow-up, between June 2007 and October 2011. Multivariate logistic and normal(More)
Severe burn induces rapid skeletal muscle proteolysis after the injury, which persists for up to 1 year and results in skeletal muscle atrophy despite dietary and rehabilitative interventions. The purpose of this research was to determine acute changes in gene expression of skeletal muscle mass regulators postburn injury. Specimens were obtained for biopsy(More)
There are reasons why survival may have improved in people with head and neck cancer, but few studies have reported on trends in the UK, and results are not consistent. We examined recent trends in survival for people diagnosed with head and neck cancer in the south west of England. Patients were identified over four one-year audits in a population (roughly(More)
