To assess the reproducibility of diagnostic results obtained by examining Pap smears for cervical neoplasia, a study was conducted using a single group of 20 Pap smears, 3 negative and 17 from patients with varying degrees of neoplasia. These smears were examined by 14 volunteer readers (13 cytotechnologists and 1 cytopathologist) from the Mexican states of Oaxaca and Veracruz, and also by a hi...

Electronic spirometers offer the prospect of paperless home monitoring, but data quality is not automatically better than from conventional monitoring. The aim of this study was to determine the extent to which the quality and processing of self-recorded spirometric data from patients with asthma complied with international guidelines for spirometry. Data were from 33 subjects with poorly contr...

In herbal medicinal products the entire herbal drug or an herbal drug preparation is regarded as the active pharmaceutical ingredient, regardless of whether constituents with defined therapeutic activity are known. In quality control and stability testing of herbal medicinal products, fingerprint chromatograms are used as powerful tools to evaluate and compare the composition of compounds in su...

Low-density microarrays that utilize short oligos (<100 nt) for capture are highly attractive for use in diagnostic applications, yet these experiments require strict quality control and meticulous reproducibility. However, a survey of current literature indicates vast inconsistencies in the spotting and processing procedures. In this study, spotting and processing protocols were optimized for ...

PURPOSE To examine adult epilepsy outpatients for the existence of the interictal dysphoric disorder (IDD) using the interictal dysphoric disorder inventory (IDDI), the overlap between IDD, depression, and anxiety, and the reproducibility of IDDI. METHODS Epilepsy outpatients were assessed with the Danish IDDI and self-report inventories for depression and anxiety. Patients with abnormal scor...

Introduction: Extensive use of diagnostic radiology is the largest contributor to total population radiation doses. Thus, appropriate equipment and safe practice are necessary for good-quality images with optimal doses. This study aimed to perform quality control (QC) audit for radiography and fluoroscopy devices owned by private sector in Syria (2005-2013) to verify compliance of performance o...

An Active Breathing Coordinator (ABC) can be employed to induce breath-holds during CT imaging and radiotherapy of lung, breast and liver cancer, and recently during lung cancer MRI. The apparatus measures and controls respiratory volume, hence subject lung volume reproducibility is its principal measure of effectiveness. To assess ABC control quality, the intra-session reproducibility of ABC-i...
