| 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.
New technology allows joint replacement on younger patients
Joint replacement surgery once was reserved for older patients suffering from knee or hip pain usually related to arthritis.
But the face of the joint replacement patient is changing, skewing younger than ever before, and the phenomenon is changing the field, according to orthopedic surgery experts.
Since joint replacement's inception in the 1970s, surgeons traditionally have been reluctant to replace joints in people younger than 70 because the devices lasted no more than 10 years. The younger the patient, the more revision surgeries would be necessary as the replacements wore out.
But now, people in their early 60s, 50s and even 40s are finding relief from the debilitating pain of arthritis with improved replacement devices, new surgical procedures and techniques, making longer lasting, more functional replacements a reality, surgeons said.
Extended-Life pH/ORP Sensor suits processing applications.
Featuring plastic-threaded connections, Rosemount� Analytical PERpH-X(TM) 3500 can handle aggressive fouling applications. Double junction AccuGlass pH glass electrode is resistant to thermal and caustic degradation, and removable slotted tip protects glass bulb from direct impacts. Replaceable porous Teflon liquid junction has surface area optimized to maintain steady reference signal, and potassium-chloride-based reference electrolyte is unaffected by thermal/pressure cycling.
