BACKGROUND: Diagnostic errors appear to be the most common, costly, and dangerous of all medical mistakes. There has been a notable increase on the focus of error prevention as part of a growing patient safety movement. However, diagnostic errors have received less attention than other types of error. Our goal is to present a short mnemonic that can act as a checklist or posted reminder to help practitioners in dermatology or any field of medicine to avoid diagnostic errors. METHODS: To meet this goal, the authors reviewed the literature and discussed errors and potential errors they have experienced over 55 years of combined practice, to create a short mnemonic...

The main purpose in the practice of pathology is to provide an accurate diagnosis. Second referral and reassessment by a second pathologist significantly cause diagnostic errors, help to make an accurate diagnosis, and improve patient management. This study was aimed to assess the general perspectives of general and oral and maxillofacial pathologists in Iran on second referrals. In this cross-sectional, descriptive-analytical study, a 20-item questionnaire on second referrals was used to assess the general and oral and maxillofacial pathologists' perspective in Iran...

PURPOSE OF REVIEW: This review aims to determine the effectiveness of the use of syndrome diagnosis in the evaluation of vaginitis and to make suggestions based on the review findings. RECENT FINDINGS: Vaginal discharge as the main symptom of vaginitis is unspecific. A randomized study of symptom-based diagnosis and treatment of vaginitis in the USA favored symptoms used for treatment; however, this was only a pilot study. Hence, a population-based study is necessary to validate these findings...

BACKGROUND: This study seeks to clarify the contribution of temporally stable and occasion-specific genetic and environmental influences on risk for major depression (MD). METHOD: Our sample was 2153 members of female-female twin pairs from the Virginia Twin Registry. We examined four personal interview waves conducted over an 8-year period with MD in the last year defined by DSM-IV criteria. We fitted a structural equation model to the data using classic Mx. The model included genetic and environmental risk factors for a latent, stable vulnerability to MD and for episodes in each of the four waves...

BACKGROUND: Proliferation may predict response to neoadjuvant therapy of breast cancer and is commonly assessed by manual scoring of slides stained by immunohistochemistry (IHC) for Ki-67 similar to ER and PgR. This method carries significant intra- and inter-observer variability. Automatic scoring of Ki-67 with digital image analysis (qIHC) or assessment of MKI67 gene expression with RT-qPCR may improve diagnostic accuracy. METHODS: Ki-67 IHC visual assessment was compared to the IHC nuclear tool (AperioTM) on core biopsies from a randomized neoadjuvant clinical trial...

Endometriosis involving the uterine cervix is a rare condition that can lead to diagnostic errors in the interpretation of Pap smear. We report the case of a 41-year-old patient in whom the initial Pap smear revealed three-dimensional clusters of glandular cells with elongated nuclei, occasional mitosis, and atypia, which was interpreted as atypical glandular cells, not otherwise specified (NOS). The patient was taken to colposcopy and endocervical biopsy. Colposcopy was normal and the biopsy presented glands with elongated nuclei and surrounded by endometrial stroma admixed with normal endocervical glands...

BACKGROUND: An early and prompt NAM diagnosis is associated with less invasive surgical procedures and a better patient's prognosis. The diagnostic delay may be related both to the clinical misinterpretations and to errors in the diagnosing process. Biopsy techniques have been adequately describe by nail experts, but the two main problems in the correct choice of the biopsy are probably related to the difficulty in performing surgery in the nail unit and the risk of permanent nail dystrophy...

Identification errors have emerged as a critical issue in health care, as testified by the ample scientific literature on this argument. Despite available evidence suggesting that the frequency of misidentification in vitro laboratory diagnostic testing may be relatively low compared to that of other laboratory errors (i.e., usually comprised between 0.01 and 0.1% of all specimens received), the potential adverse consequences remain particularly worrying, wherein 10-20% of these errors not only would translate into serious harm for the patient, but may also erode considerable human and economic resources, so that the entire healthcare system should be re-engineered to act proactively and limiting the burden of this important problem...

Veterinary clinical pathologists are well positioned via education and training to assist in investigations of unexpected results or increased variation in clinical pathology data. Errors in testing and unexpected variability in clinical pathology data are sometimes referred to as "laboratory errors." These alterations may occur in the preanalytical, analytical, or postanalytical phases of studies. Most of the errors or variability in clinical pathology data occur in the preanalytical or postanalytical phases...

Diagnostic imaging plays an important role in the operating room, providing surgeons with a reference and surgical plan. Surgeon autonomy in the operating room has been suggested to decrease errors that stem from communication mistakes. A standard computer mouse was compared to a wireless remote-control style controller for computer game consoles (Wiimote) for the navigation of diagnostic imaging studies by sterile personnel in this prospective survey study. Participants were recruited from a cohort of residents and faculty that use the surgical suites at our institution...

An important priority in the current healthcare scenario should be to address errors in laboratory testing, which account for a significant proportion of diagnostic errors. Efforts made in laboratory medicine to enhance the diagnostic process have been directed toward improving technology, greater volumes and more accurate laboratory tests being achieved, but data collected in the last few years highlight the need to re-evaluate the total testing process (TTP) as the unique framework for improving quality and patient safety...
