BACKGROUND & AIMS An association between diabetes and chronic liver disease has been reported. However, the temporal relationship between these conditions remains unknown. METHODS We identified all patients with a hospital discharge diagnosis of diabetes between 1985 and 1990 using the computerized records of the Department of Veterans Affairs. We(More)
OBJECTIVES The epidemiology of gastrointestinal stromal tumor has not been well examined, and prior studies often provide conflicting results. We conducted the first population-based study to evaluate the incidence and survival of malignant gastrointestinal stromal tumor in the United States. METHODS We utilized the Surveillance, Epidemiology, and End(More)
BACKGROUND Three patients who received visceral-organ transplants from a single donor on the same day died of a febrile illness 4 to 6 weeks after transplantation. Culture, polymerase-chain-reaction (PCR) and serologic assays, and oligonucleotide microarray analysis for a wide range of infectious agents were not informative. METHODS We evaluated RNA(More)
A critical component of laboratory surveillance for measles is the genetic characterization of circulating wild-type viruses. The World Health Organization (WHO) Measles and Rubella Laboratory Network (LabNet), provides for standardized testing in 183 countries and supports genetic characterization of currently circulating strains of measles viruses. The(More)
Respiratory viruses were identified by the polymerase chain reaction (PCR) in more than 4,200 specimens collected during 2002 and 2003 in Victoria, Australia from patients admitted to hospitals or participating in an influenza surveillance program. Influenza viruses and picornaviruses were important causes of morbidity in both years. Additional testing of(More)
OBJECTIVE To investigate changes in the proportions of patients infected with genital herpes simplex virus (HSV) types 1 and 2 from 1980 to 2003 in Melbourne, Australia. METHODS A total of 25 372 patients were studied retrospectively. The proportions of HSV-1 and HSV-2 detected in these individuals were analysed by age, sex, and genital site. RESULTS In(More)
OBJECTIVE Obesity may increase intra-abdominal pressure on the stomach leading to an increase in intragastric pressure, which in turn induces lower esophageal sphincter relaxation, with subsequent reflux. However, the association between anthropometric measures of total body as well as abdominal obesity and intragastric pressure has not been examined. (More)
Conflicting findings regarding the level of protection offered by seasonal influenza vaccination against pandemic influenza H1N1 have been reported. We performed a test-negative case control study using sentinel patients from general practices in Victoria to estimate seasonal influenza vaccine effectiveness against laboratory proven infection with pandemic(More)
Three outbreaks of respiratory illness associated with human coronavirus HCoV-OC43 infection occurred in geographically unrelated aged-care facilities in Melbourne, Australia during August and September 2002. On clinical and epidemiological grounds the outbreaks were first thought to be caused by influenza virus. HCoV-OC43 was detected by RT-PCR in 16 out(More)
We used a sentinel general practitioner (GP) network to conduct surveillance for laboratory-confirmed influenza amongst patients presenting with influenza-like illness (ILI) in Victoria, Australia in 2011. The test negative variation of the case control study design was used to estimate effectiveness for seasonal trivalent influenza vaccine. Cases and(More)
