Personalizing Surveillance in Head and Neck Cancer.

Head and neck squamous cell carcinoma (HNSCC) encompasses a spectrum of heterogeneous diseases originating in the oral cavity, pharynx, and larynx. Within the United States, head and neck cancer (HNC) accounts for 66,470 new cases, or 3% of all malignancies, annually. The incidence of HNC is rising, largely driven by increases in oropharyngeal cancer.

Analyzing color imaging failure on consumer-grade cameras.

There are many efforts to employ consumer-grade cameras for home-based health and wellness monitoring. Such applications rely on users to capture images for analysis using their personal cameras in a home environment. When color is a primary feature for diagnostic algorithms, the camera requires calibration to ensure accurate color measurements.

Hazards with ordering troponin in patients with low pretest probability of acute coronary syndrome.

Background: In clinical practice, we progressively rely on biomarkers, without estimating the pretest probability. There is not enough support for the use of cardiac troponin (cTn) I in the management of noncardiac patients. We studied the rate at which this test was ordered, the prevalence of detection of a positive result in noncardiac patients, and the impact of this incidental finding on clinical management.

Preparation and evaluation of mucoadhesive cefdinir microcapsules.

The mucoadhesive microcapsules were prepared by using various concentrations of three different mucoadhesive polymers, namely, chitosan, Carbopol 934P, and methyl cellulose as wall materials and cefdinir as the core material employing orificeionic gelation method. The prepared microcapsules were characterized by scanning electron microscope (SEM) and Fourier transform infrared spectrometry (FT-IR). The prepared microcapsules were found to be spherical with particle size ranging from 765±20 to 985±10 μm and encapsulation efficiencies in the range of 55%-92%.

The use of questionnaires for the identification of high risk areas for urinary schistosomiasis: the Ethiopian experience.

The applicability and usefulness of questionnaires directed at school children and teachers and routed through the usual administrative/educational system for the identification of communities at risk for urinary schistosomiasis in Ethiopia was assessed in the Awash Valley in 1992 as part of a multi-country study. Pre-tested questionnaires were distributed to 28 elementary schools. A total of 2918 children and 56 teachers completed the questionnaires.
