| Tuberculosis Breaches Borders, But Not Public Health
Immigrants from countries with high rates of tuberculosis who move to countries of low TB incidence do not pose a public health threat to native citizens, according to researchers in Norway, who analyzed the incidence and genetic origins of all known cases of TB in the country between 1993 and 2005.
Their results were reported in the first issue for November of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
After gathering all available cultures from the identified cases and eliminating samples suspected of being contaminated in the lab, the researchers examined 2,173 cases of TB in the country over 12 years. They tracked outbreaks among native-born citizens and immigrants, and analyzed the genetic strain of each confirmed case using cultures obtained through patient samples at 14 laboratories that service the entire country.
Jehovah's Witness mother dies after refusing blood
A 22-year-old woman died within a few hours of giving birth to twins because, as a Jehovah's Witness, she was not allowed to accept a blood transfusion, it emerged today. Emma Gough suffered severe blood loss after giving birth to a boy and girl at the Royal Hospital in Shrewsbury ten days ago. Doctors and medics begged her 24-year-old husband, Anthony, and other relatives to overrule a form she had ticked insisting that she should not be given blood because of her faith. But the family refused to do so. .
USC School Of Dentistry Researchers Discover Link Between Oral Cancer And Ethnicity
Clinicians from the USC School of Dentistry unravel connection between the incidence of oral cancer and race and ethnicity-- as part of first epidemiological study of oral cancer in California. Dr. Satish Kumar and Dr.Parish Sedghizadeh, clinical professors in the school's Division of Diagnostic Sciences, gleaned through 20 years of records from the California Cancer Registry (CCR)-the state's cancer surveillance database-for the incidence rates of invasive squamous cell carcinoma, the most common form of oral cancer.
Their findings will be published in an upcoming issue of the journal Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology and are currently available online at http://www.ooooe.net.
Kumar and Sedghizadeh theorized that groups who engaged in these high-risk behaviors would also experience higher rates of oral cancer.
