*  Advances in Cognitive Psychology

The P3 component of event-related potentials increases when stimuli are rarely presented. It has been assumed that this oddball effect (rare-frequent difference) reflects the unexpectedness of rare stimuli. The assumption of unexpectedness and its link to P3 amplitude were tested here. A standard-oddball task requiring alternative key-press responses to frequent and rare stimuli was compared with an oddball-prediction task where stimuli had to be first predicted and then confirmed by key-pressing. Oddball effects in the prediction task depended on whether the frequent or the rare stimulus had been predicted. Oddball effects on P3 amplitudes and error rates in the standard oddball task closely resembled effects after frequent predictions. This corroborates the notion that these effects occur because frequent stimuli are expected and rare stimuli are unexpected. However, a closer look at the prediction task put this notion into doubt because the modifications of oddball effects on P3 by ...

I'd like to take a closer look at the RNC platform statement about protecting Americans.

Hey, here they are, finally listening to their federal safety personel, namely the secret service, but they don't think the American public deserves federal protection. While they criticized Clinton for wanting to protect himself and not the public, they are now doing even worse! They are saying that the public should have minimum wage security personel that are employed by the lowest bidders. Meanwhile, the hypocritical Resident in Chief has plenty of federalized protection, including a now permanently closed Pennsylvania Ave. which they said they would re-open.

Prenatal diagnosis: Prenatal diagnosis or prenatal screening (note that prenatal diagnosis and prenatal screening refer to two different types of tests) is testing for diseases or conditions in a fetus or embryo before it is born. The aim is to detect birth defects such as neural tube defects, Down syndrome, chromosome abnormalities, genetic disorders and other conditions, such as spina bifida, cleft palate, Tay Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, Muscular dystrophy, and fragile X syndrome.Assay sensitivity: Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. Without assay sensitivity, a trial is not internally valid and is not capable of comparing the efficacy of two interventions.Prescription cascade: Prescription cascade refers to the process whereby the side effects of drugs are misdiagnosed as symptoms of another problem resulting in further prescriptions and further side effects and unanticipated drug interactions. This may lead to further misdiagnoses and further symptoms.Dense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.Brain biopsyRavindra Nanda: Ravindra Nanda (born 19 February 1943) is the professor and Head of Craniofacial Department and Chair of the Division of Orthodontics at the University of Connecticut School of Dental Medicine.Computer-aided diagnosis: In radiology, computer-aided detection (CADe), also called computer-aided diagnosis (CADx), are procedures in medicine that assist doctors in the interpretation of medical images. Imaging techniques in X-ray, MRI, and Ultrasound diagnostics yield a great deal of information, which the radiologist has to analyze and evaluate comprehensively in a short time.Generalizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Yury VerlinskyTemporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingHyperintensityQRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Thermal cyclerGross examinationBreast biopsyIncidence (epidemiology): Incidence is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time period, it is better expressed as a proportion or a rate with a denominator.Age adjustment: In epidemiology and demography, age adjustment, also called age standardization, is a technique used to allow populations to be compared when the age profiles of the populations are quite different.Prevalence: Prevalence in epidemiology is the proportion of a population found to have a condition (typically a disease or a risk factor such as smoking or seat-belt use). It is arrived at by comparing the number of people found to have the condition with the total number of people studied, and is usually expressed as a fraction, as a percentage or as the number of cases per 10,000 or 100,000 people.Biomarkers of aging: Biomarkers of aging are biomarkers that better predict functional capacity at a later age than chronological age. Stated another way, biomarkers of aging would give the true "biological age", which may be different from the chronological age.Nested case-control study: A nested case control (NCC) study is a variation of a case-control study in which only a subset of controls from the cohort are compared to the incident cases. In a case-cohort study, all incident cases in the cohort are compared to a random subset of participants who do not develop the disease of interest.Eva Engvall: Eva Engvall, born 1940, is one of the scientists who invented ELISA in 1971.Eva Engvall, The Scientist 1995, 9(18):8Malformative syndrome: A malformative syndrome (or malformation syndrome) is a recognizable pattern of congenital anomalies that are known or thought to be causally related (VIIth International Congress on Human Genetics).List of Parliamentary constituencies in Kent: The ceremonial county of Kent,Abdominal ultrasonographyCancer biomarkers: A cancer biomarker refers to a substance or process that is indicative of the presence of cancer in the body. A biomarker may be a molecule secreted by a tumor or a specific response of the body to the presence of cancer.GeneXpert MTB/RIFFine-needle aspiration: Fine-needle aspiration biopsy (FNAB, FNA or NAB), or fine-needle aspiration cytology (FNAC), is a diagnostic procedure used to investigate superficial (just under the skin) lumps or masses. In this technique, a thin, hollow needle is inserted into the mass for sampling of cells that, after being stained, will be examined under a microscope.Breast cancer classification: Breast cancer classification divides breast cancer into categories according to different schemes, each based on different criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes.Full-body CT scan: A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography (CAT) scan technology is used, it is known as a full-body CT scan, though many medical imaging technologies can perform full-body scans.TSOM: Through-Focus Scanning Optical Microscopy (TSOM) is an imaging method that produces nanometer-scale three-dimensional measurement sensitivity using a conventional bright-field optical microscope.

Registries are different from indexes in that they contain more extensive data.Closed-ended question: A closed-ended question is a question format that limits respondents with a list of answer choices from which they must choose to answer the question.Dillman D.Comorbidity: In medicine, comorbidity is the presence of one or more additional disorders (or diseases) co-occurring with a primary disease or disorder; or the effect of such additional disorders or diseases. The additional disorder may also be a behavioral or mental disorder.Referral (medicine): In medicine, referral is the transfer of care for a patient from one clinician to another.García Olmos L, Gervas Camacho J, Otero A, Pérez Fernández M.Cancer screeningClonal Selection Algorithm: In artificial immune systems, Clonal selection algorithms are a class of algorithms inspired by the clonal selection theory of acquired immunity that explains how B and T lymphocytes improve their response to antigens over time called affinity maturation. These algorithms focus on the Darwinian attributes of the theory where selection is inspired by the affinity of antigen-antibody interactions, reproduction is inspired by cell division, and variation is inspired by somatic hypermutation.Global Risks Report: The Global Risks Report is an annual study published by the World Economic Forum ahead of the Forum’s Annual Meeting in Davos, Switzerland. Based on the work of the Global Risk Network, the report describes changes occurring in the global risks landscape from year to year and identifies the global risks that could play a critical role in the upcoming year.Tumor progression: Tumor progression is the third and last phase in tumor development. This phase is characterised by increased growth speed and invasiveness of the tumor cells.Endobronchial valve: An endobronchial valve is an implantable medical device—a small, one-way valve, which is implanted in an airway in the pulmonary system to treat one of several lung conditions. The one-way endobronchial valve is typically implanted such that when a patient exhales, air is able to flow through the valve and out of the lung compartment that is fed by that airway, but when the patient inhales, the valve closes and blocks air from entering that lung compartment.Cancer survival rates: Cancer survival rates vary by the type of cancer, stage at diagnosis, treatment given and many other factors, including country. In general survival rates are improving, although more so for some cancers than others.RDCRN Contact Registry: The Rare Diseases Clinical Research Network (RDCRN) Contact Registry is an international patient contact registry sponsored by the National Institutes of Health. This registry collects basic data (i.Stichosome: Stichosome (from Greek stichos (στίχος) = row; soma (σῶµα) = body) is a multicellular organ that is very prominent in some stages of nematodes and consists of a longitudinal series of glandular unicellular cells (stichocytes) arranged in a row along the oesophagus that form the posterior esophageal glands. It opens into the esophageal lumen and apparently functions as a secretory gland and storage organ.Non-communicable disease: Non-communicable disease (NCD) is a medical condition or disease that is non-infectious or non-transmissible. NCDs can refer to chronic diseases which last for long periods of time and progress slowly.Death of Ludwig van Beethoven: The death of Ludwig van Beethoven on 26 March 1827 followed a prolonged illness. It was witnessed by his sister-in-law and by his close friend Anselm Hüttenbrenner, who provided a vivid description of the event.Targeted therapy of lung cancer: Targeted therapy of lung cancer refers to using agents specifically designed to selectively target molecular pathways responsible for, or that substantially drive, the malignant phenotype of lung cancer cells, and as a consequence of this (relative) selectivity, cause fewer toxic effects on normal cells.Immunoassay: An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule in a solution through the use of an antibody or immunoglobulin. The macromolecule detected by the immunoassay is often referred to as an "analyte" and is in many cases a protein.Old German Shepherd Dog: Old German Shepherd Dog () is a controversial predicate for the long-hair variation of the German Shepherd Dog (), which is not a separate breed recognized by the Fédération Cynologique Internationale. Nonetheless, there are efforts to establish this variety as a separate breed.International Statistical Classification of Diseases and Related Health Problems: The International Statistical Classification of Diseases and Related Health Problems, usually called by the short-form name International Classification of Diseases (ICD), is the international "standard diagnostic tool for epidemiology, health management and clinical purposes".

(1/65) Overbite depth and anteroposterior dysplasia indicators: the relationship between occlusal and skeletal patterns using the receiver operating characteristic (ROC) analysis.

This study was carried out to investigate the validity of the overbite depth indicator (ODI) and the anteroposterior dysplasia indicator (APDI), based on the cephalometric analysis of 122 Caucasians selected at random for assessment of vertical and sagittal relationships. Considering the occlusion, the sample was divided into three classifications in the sagittal component: 36 cases of neutrocclusion, 54 cases of distocclusion, and 34 cases of mesiocclusion. The sample was also categorized according to the overbite relationship: 54 cases of normal overbite, 34 cases of open bite, and 34 cases of deep overbite. In the sagittal component analysis, the APDI measurement resulted in significant differences between the neutrocclusion, distocclusion, and mesiocclusion groups. In the vertical component analysis, the ODI significantly distinguished between the normal and deep overbite groups, and the open bite and deep overbite groups, but not between the normal overbite and the open bite groups. A receiver operating characteristic (ROC) analysis showed that the APDI matched the anteroposterior molar relationship in 88 per cent, and the ODI matched the amount of incisor overbite in 81 per cent.  (+info)

(2/65) Quality evaluation of clinical records of a group of general dental practitioners entering a quality assurance programme.

This paper discusses the importance of maintaining high quality clinical records. Evidence from studies carried out in the USA, Australia and Scandinavia shows that record keeping often falls well below accepted standards. Evidence of current standards in the UK, however, has tended to be anecdotal or circumstantial. An assessment was carried out on 47 general practitioners entering the quality assurance programme of a private capitation scheme. A sample of clinical records from each practitioner was analysed, and the presence or absence of key diagnostic and treatment planning entries were recorded. Overall, the quality of record keeping was poor, and in line with the findings of the other worldwide studies. Fundamental clinical entries that could impact on basic dental care provision were missing from many records. The frequency of recording for patients whose treatment was funded under NHS regulations was significantly worse than for patients whose treatment was privately funded.  (+info)

(3/65) Evidence-based Dentistry: Part VI. Critical Appraisal of the Dental Literature: Papers About Diagnosis, Etiology and Prognosis.

Critical appraisal methods assist the reader in assessing the validity (closeness to the truth) and the relevance (usefulness in everyday practice) of research findings. The specific techniques of critical appraisal can vary somewhat, depending on the nature of the research question. In this paper, the final in a 6-part series on evidence-based dentistry, frameworks are presented to enable the judicious reader of the dental literature to apply sensible questions to the evaluation of papers related to diagnosis, etiology and prognosis.  (+info)

(4/65) Salivary markers of systemic disease: noninvasive diagnosis of disease and monitoring of general health.

Because of interest in the link between oral and general health, clinicians are increasingly using salivary analyses to diagnose systemic disease and to monitor general health. The reason for this interest lies in the ability of new diagnostic tools, such as sensitive enzyme-linked immunosorbent assays, as well as other technologies, to distinguish a range of salivary components that are biomarkers for changes in the body's health. The noninvasive nature of salivary testing has made it an attractive and effective alternative to blood and urine testing, and home testing kits have made it possible for people to monitor their own health using this diagnostic medium. This paper explores what saliva can reveal about general health, drawing examples from recent research on salivary biomarkers of systemic illness and highlighting the current use, and potential clinical and research applications, of diagnostics based on oral fluids.  (+info)

(5/65) Making a comprehensive diagnosis in a comprehensive care curriculum.

Comprehensive care models in dental education encourage students to deliver patient-centered care. But to deliver effective comprehensive care, a clinician must first make a comprehensive diagnosis. Students of general dentistry are taught to make one or more diagnoses as defined by the dental specialties, and to direct patient care accordingly. Without a comprehensive diagnosis, patients may receive fragmented, poorly prioritized care that is inappropriate to their overall oral health. This paper presents a simple diagnostic classification that can be used to make a comprehensive diagnosis with which to guide the student of general dentistry in planning comprehensive care.  (+info)

(6/65) Malocclusions in guinea pigs, chinchillas and rabbits.

The types of malocclusions encountered in rodents and lagomorphs are classified. Diagnosis, treatment, and prognosis are reviewed. Some malocclusions are curable, whereas others can only be controlled. The need to perform a complete oral examination and to find a cause for the condition is stressed, as it will seriously affect the prognosis.  (+info)

(7/65) Application of thermography in dentistry--visualization of temperature distribution on oral tissues.

The purpose of this study was to devise and propose appropriate conditions for the photographing of thermal images in the oral cavity and to evaluate which thermography techniques can be applied to dentistry by evaluating the differences in temperature among oral tissues. Thermal images of oral cavities of 20 volunteers in normal oral condition were taken according to the guidelines of the Japanese Society of Thermography, with five added items for oral observation. The use of a mirror made it possible to take thermal images of the posterior portion or palate. Teeth, free gingiva, attached gingiva and alveolar mucosa were identified on thermal images. There were differences in temperature between teeth, free gingiva, attached gingiva and alveolar mucosa. These were nearly in agreement with the anatomical view. Thermography need no longer be restricted to the anterior portion using a mirror, and can now be applied to the dental region.  (+info)

(8/65) A closer look at diagnosis in clinical dental practice: part 1. Reliability, validity, specificity and sensitivity of diagnostic procedures.

Dentists are involved in diagnosing disease in every aspect of their clinical practice. A range of tests, systems, guides and equipment--which can be generally referred to as diagnostic procedures--are available to aid in diagnostic decision making. In this era of evidence-based dentistry, and given the increasing demand for diagnostic accuracy and properly targeted health care, it is important to assess the value of such diagnostic procedures. Doing so allows dentists to weight appropriately the information these procedures supply, to purchase new equipment if it proves more reliable than existing equipment or even to discard a commonly used procedure if it is shown to be unreliable. This article, the first in a 6-part series, defines several concepts used to express the usefulness of diagnostic procedures, including reliability and validity, and describes some of their operating characteristics (statistical measures of performance), in particular, specificity and sensitivity. Subsequent articles in the series will discuss the value of diagnostic procedures used in daily dental practice and will compare today's most innovative procedures with established methods.  (+info)


  • When a 26-year-old man presented with an asymptomatic submucosal fibroelastic nodule covered by normal-appearing mucosa in the hard palate, the working diagnosis was minor salivary gland tumor, but histologic analysis of the biopsy specimen revealed the characteristic cellular patterns of a schwannoma. (

  • The information provided by is not a substitute for professional medical advice, diagnosis or treatment. (
  • Before pursuing a ringworm treatment, a proper diagnosis needs to take place. (
  • A ringworm treatment will not help these other skin care problems and therefore, the proper ringworm diagnosis is imperative for a proper cure to be implemented. (
  • A more certain diagnosis before suggesting a ring worm treatment is performed via skin scrapings. (
  • Early diagnosis and aggressive treatment are essential to mitigate the cascading events that lead to irreversible joint erosion in rheumatoid arthritis. (
