CONTEXT Increasing cancer incidence is typically interpreted as an increase in the true occurrence of disease but may also reflect changing pathological criteria or increased diagnostic scrutiny. Changes in the diagnostic approach to thyroid nodules may have resulted in an increase in the apparent incidence of thyroid cancer. OBJECTIVE To examine trends(More)
IMPORTANCE We have previously reported on a doubling of thyroid cancer incidence-largely due to the detection of small papillary cancers. Because they are commonly found in people who have died of other causes, and because thyroid cancer mortality had been stable, we argued that the increased incidence represented overdiagnosis. OBJECTIVE To determine(More)
BACKGROUND Cancer rates of the head and neck are traditionally linked to public health issues. OBJECTIVE To describe the epidemiology of head and neck cancer in the United States. DESIGN AND SETTING National Cancer Institute's Surveillance Epidemiology and End Results (SEER) program. RESULTS A total of 75,000 cases of head and neck cancer were(More)
BACKGROUND The rapidly rising incidence of papillary thyroid cancer may be due to overdiagnosis of a reservoir of subclinical disease. To conclude that overdiagnosis is occurring, evidence for an association between access to health care and the incidence of cancer is necessary. METHODS We used Surveillance, Epidemiology, and End Results (SEER) data to(More)
OBJECTIVE To describe time trends in total laryngectomy health services utilization across the United States, such as rates of surgery, cost, length of stay, and insurance payer, and to compare this to important milestones in recommendations for laryngeal cancer treatment. STUDY DESIGN Population-based cohort study. SETTING Healthcare Cost and(More)
OBJECTIVE/HYPOTHESIS To report data on death or permanent disability after tonsillectomy. STUDY DESIGN Electronic mail survey. METHODS A 32-question survey was disseminated via the American Academy of Otolaryngology-Head and Neck Surgery electronic newsletter. Recipients were queried regarding adverse events after tonsillectomy, capturing demographic(More)
OBJECTIVE To compare the survival rate of people with papillary thyroid cancer limited to the thyroid gland who have not had immediate, definitive treatment for their thyroid cancer with the survival rate of those who have had such treatment. DESIGN Cohort study of incident cancer cases and initial treatment data from the National Cancer Institute's(More)
In order to quantify motor disabilities in Parkinson's disease (PD), we designed a compact, portable, neurophysiological system based upon a personal computer to measure tremor, bradykinesia, and muscle tone. Tremor was detected by solid state accelerometers and translated into a digital signal. The system displayed the root mean square displacements and(More)
The activation of motoneurons in a muscle pool is said to proceed as an ordered array in response to both dorsal root stimulation and voluntary activation, with small motoneurons being recruited before larger ones. We have examined 19 voluntarily recruited soleus motor units in 5 normal subjects and found that in 18 cases, the lowest threshold motor unit(More)
BACKGROUND Contrast-induced acute kidney injury (CI-AKI) is associated with increased morbidity and mortality after percutaneous coronary interventions and is a patient safety objective of the National Quality Forum. However, no formal quality improvement program to prevent CI-AKI has been conducted. Therefore, we sought to determine whether a 6-year(More)
