Purpose: Clinicians often test laryngeal sensation by touching the laryngeal mucosa with the tip of a flexible laryngoscope. However, the pressure applied to the larynx by using this touch method is unknown, and the expected responses elicited by this method are uncertain. The variability in pressure delivered by clinicians using the touch method was investigated, and the subject responses to the touches were also reported. Methods: A fiberoptic pressure sensor passed through the working channel of a laryngoscope, with its tip positioned at the distal port of the channel...

The prospective banking of osteosarcoma tissue samples to promote research endeavors has been realized through the establishment of a nationally centralized biospecimen repository, the Children's Oncology Group (COG) biospecimen bank located at the Biopathology Center (BPC)/Nationwide Children's Hospital in Columbus, Ohio. Although the physical inventory of osteosarcoma biospecimens is substantive (>15,000 sample specimens), the nature of these resources remains exhaustible. Despite judicious allocation of these high-value biospecimens for conducting sarcoma-related research, a deeper understanding of osteosarcoma biology, in particular metastases, remains unrealized...

An outbreak of Ebola virus disease (EVD) in Liberia began in March 2014 and ended in January 2016. Epidemiological information on the EVD cases was collected and managed nationally; however, collection and management of the data were challenging at the time because surveillance and reporting systems malfunctioned during the outbreak. EVD diagnostic laboratories, however, were able to register basic demographic and clinical information of patients more systematically. Here we present data on 16,370 laboratory samples that were tested between April 4, 2014 and March 29, 2015...

INTRODUCTION: Endoscopic resection is the first option treatment of early gastric cancer with invasion to mucosa or superficial submucosa, because the risk of nodal metastasis is negligible. Then the prediction of tumor invasion is cardinal. OBJECTIVES: Determine the accuracy of endoscopic prediction for tumor invasion depth in early gastric neoplasia and define endoscopic characteristics associated with massive submucosal invasion. MATERIALS AND METHODS: Prospective sudy of diagnostic test validation...

There are relatively limited data on outcomes of screening older adults for cancer; therefore, the decision to screen older adults requires balancing the potential harms of screening and follow-up diagnostic tests with the possibility of benefit. Harms of screening can be amplified in older and frail adults and include discomfort from undergoing the test itself, anxiety, potential complications from diagnostic procedures resulting from a false-positive test, false reassurance from a false-negative test, and overdiagnosis of tumors that are of no threat and may result in overtreatment...

OBJECTIVE: Snoring is a common reason for referral to a sleep unit. Although there are several instruments to measure snoring, there is no gold standard for this purpose. In this study, we determine the diagnostic accuracy of the cannula as compared with the microphone, which are the two most commonly used tools. STUDY DESIGN: We performed a cross-sectional study of 75 patients who underwent baseline home sleep apnea testing for any reason. METHODS: Snore intensity and percentage were assessed during Home sleep-apnea testing via nasal cannula and microphone in all patients...

PURPOSE: Prostate specific antigen (PSA) has been widely used as the unique serum biomarker for the diagnosis and/ or pre-diagnosis of prostate cancer (PCa). However, the diagnostic value of PSA is a subject of ongoing debate owing to its lack of specificity, especially when the PSA level is moderately increased (e.g., 4-10 ng/ml). Thus, we suggest the need for identification of a new biomarker to discriminate PCa cases from benign prostatic hyperplasia (BPH) and normal controls (N). METHODS: Urine or tissue samples of PCa patients, BPH patients, and normal controls were systematically collected...

BACKGROUND: Clostridium difficile is a major cause of health care-associated infection, but disagreement between diagnostic tests is an ongoing barrier to clinical decision making. Conventional enzyme immunoassay (EIA) for toxin detection is currently the most frequently used technique for CDI diagnosis, but its low sensitivity makes the development of an alternative strategy necessary for improving the diagnosis in developing countries. METHODS: Between years 2011 and 2015, 154 stool samples from patients with antibiotic-associated diarrhea were examined by toxigenic culture (TC) and EIA for the diagnosis of CDI...

Nutrition-related policy, system, and environmental (PSE) interventions such as farmers' markets have been recommended as effective strategies for promoting healthy diet for chronic disease prevention. Tools are needed to assess community readiness and capacity factors influencing successful farmers' market implementation among diverse practitioners in different community contexts. We describe a multiphase consensus modeling approach used to develop a diagnostic tool for assessing readiness and capacity to implement farmers' market interventions among public health and community nutrition practitioners working with low-income populations in diverse contexts...

p16÷Ki-67 dual-stained cytology, either alone or combined with human papillomavirus (HPV) 16÷18 genotyping, could be a useful tool for triage for colposcopy of HPV-positive patients. Based on this background, we aimed at comparing the diagnostic performance of the p16÷Ki-67 dual staining test, and high-risk HPV test for the detection of high-risk cervical intraepithelial neoplasia (CIN2÷3) in patients diagnosed with low-grade squamous intraepithelial lesion (LSIL) on Pap smear. We performed a retrospective study including 184 patients with LSIL cytology on Pap smear, of which 64 were referred for biopsy after colposcopy...

Since they were described, gastrointestinal stromal tumors (GISTs) are, for pathologists and not only for them, a subject of controversy regarding histological origin, differentiation, nomenclature, malignant potential and prognosis. Before 1998, there were no certainties that GISTs were fundamentally different from other types of abdominal cancers in the big family of mesenchymal tumors. Before the discovery of KIT gene mutations, GISTs were most often classified as leiomyoma, leiomyosarcoma, leiomyoblastoma, and gastrointestinal autonomic nerve tumor...

Perinatal autopsy remains the gold-standard procedure used to establish the fetal, neonatal or infant abnormalities. Progressively, perinatal pathology has become a specialized field with important roles of audit for fetal prenatal diagnostic tools, in parents counseling regarding future pregnancies, in scientific research, for epidemiology of congenital abnormalities and teaching. The differences between prenatal ultrasound and autopsy reports represent a strong argument for the autopsy examination following termination of pregnancy...

In drug invention and early disease prediction of lung cancer, metabolomic biomarker detection is very important. Mortality rate can be decreased, if cancer is predicted at the earlier stage. Recent diagnostic techniques for lung cancer are not prognosis diagnostic techniques. However, if we know the name of the metabolites, whose intensity levels are considerably changing between cancer subject and control subject, then it will be easy to early diagnosis the disease as well as to discover the drug. Therefore, in this paper we have identified the influential plasma and serum blood sample metabolites for lung cancer and also identified the biomarkers that will be helpful for early disease prediction as well as for drug invention...
