PURPOSE: To evaluate the effects of 2 noise reduction techniques on the auditory brainstem response (ABR). METHOD: ABRs of 20 normal hearing adults were recorded during quiet and active behavioral conditions using 2 stimulus intensity levels. Wave V…
Data from the 2004 National Physician Survey were used to determine when current Canadian radiologists made their decision to pursue a radiology career and to determine which factors were most influential in their decision. Most respondents reported…
Three recently published Institute of Medicine reports, Hospital-Based Emergency Care: At the Breaking Point, Emergency Medical Services: At the Crossroads, and Emergency Care for Children: Growing Pains, examined the current state of emergency care…
Polio may now be considered a disease of the past in the United States; however, the effects of this epidemic on its survivors continue to emerge. Many polio survivors, now in their 40s and older, report the emergence of new, progressive, and…
Objective: The outcomes of 61 patients who underwent a pharyngoplasty for velopharyngeal insufficiency were reviewed to determine potential risk factors for reoperation.Design: This was a retrospective chart review of 61 consecutive patients over…
The challenge for the practitioner is to balance incomplete evidence about efficacy of medications in frail older people against the problems related to adverse drug reactions without denying people potentially valuable pharmacotherapeutic…
The American Diabetes Association recommends routine screening for albuminuria to detect early nephropathy in all patients with diabetes mellitus. If nephropathy is identified, treatment with an antiangiotensin agent decreases progression and…
Adults who exercise regularly have better health, but only 15% of U.S. adults engage in regular exercise, with some social groups, such as people with lower incomes and women, having even lower rates. This study investigates the rate at which…
This column discusses ways that states can implement community-based best practices statewide, by using the crisis intervention team (CIT) model as an example. Although state mental health authorities may want to use a topdown approach to ensure…
The Sequential Intercept Model provides a conceptual framework for communities to use when considering the interface between the criminal justice and mental health systems as they address concerns about criminalization of people with mental illness.…
The skulls and isolated tympanics are described for the earliest whales, pakicetids, from the H-GSP Locality 62 in the Ganda Kas area in Northern Pakistan. Currently three pakicetid genera are known: Pakicetus, Ichthyolestes, and Nalacetus.…
The marsupial middle ear performs an anatomical impedance matching for acoustic energy travelling in air to reach the cochlea. The size of the middle ear sets constraints for the frequencies transmitted. For generalized placental mammals, it has been…
We have generated immortal neuronal cell lines from normal and trisomy 16 (Ts16) mice, a model for Down syndrome (DS). Ts16 lines overexpress DS-related genes (App, amyloid precursor protein; Sod1, Cu/Zn superoxide dismutase) and show altered…
Objective. The purpose of this series is to describe the prenatal echocardiographic findings of vascular rings. Methods. The 3-vessel and trachea view consists of the axial view of the upper mediastinum. The normal left aortic arch appears as a…
Objective. The purpose of this series was to describe the fetal echocardiographic findings in hypoplastic left heart syndrome with aortic atresia and ventriculocoronary arterial communication and implications of these findings. Methods. We describe 2…
One of the intents of tissue engineering is to fabricate biological materials for the augmentation or replacement of impaired, damaged, or diseased human tissue. In this context, novel models of the human phalanges have been developed recently…
The construct of "other-directed versus self-directed career choice" has existed for quite some time. The current focus of vocational psychologists and counselors has made them question the relevance of this construct for contemporary American…
There is significant diversity in growth plate behavior among sites within an individual skeleton and between skeletons of different species. This variation within wild-type animals is an underutilized resource for studying skeletal development. One…
Bejel clearly has a long history in the Middle East and the Sudan, but was it transmitted to Europe? As the major manifestation of bejel is presence of periosteal reaction in 20-40% of afflicted populations, absence of significant population…
The hypothesis of disease-related large mammal extinction has new support. A unique pathologic zone of resorption was first noticed in a Hiscock Mammut americanum metacarpal. The pathognomonic zone of resorption was present in fifty-nine (52%) of 113…
The purpose of this study was to assess birds as a potential model for osteoarthritis. Compromised by confounding factors, it has not been possible to clearly delineate causation in humans. Nonhuman mammals manifest osteoarthritis in the natural…
Objectives. Because several experimental studies have demonstrated that cyclic adenosine monophosphate generation following beta-adrenoceptor activation can markedly stimulate alveolar fluid clearance, we determined whether the endogenous levels of…
Background/Aims: Hemodialysis patients are often hospitalized, during which time they require continuity of care in the inpatient setting. The goal of the present study was to evaluate the clinical outcomes associated with a conversion algorithm from…
As part of a broader effort to identify postreceptor signal regulators involved in specific diseases or organ adaptation, we used an expression cloning system in Saccharomyces cerevisiae to screen cDNA libraries from rat ischemic myocardium, human…
Objectives: The aim of this study was to correlate the anatomic and clinical significance of the prepubic course of dorsal nerve of penis and its groove on the pubic bone from the perspective of the surgeon. Methods: The course of the dorsal nerve of…
The transcription of the cholesterol 7 alpha-hydroxylase gene (CYP7A1) is greatly decreased in cholesterol-fed rabbits. To determine whether the molecular structure of the promoter is responsible for this downregulation, we cloned the rabbit CYP7A1…
A complex plasma disc (CPD) is a stable two-dimensional arrangement of it particles, each with mass in and charge q, confined by a parabolic well and interacting through a shielded Coulomb force (i.e. a Yukawa potential). It is shown that the…
Background: Foot burns in children often result from contact with heated surfaces due to high ambient temperatures during summer in the southwestern United States. The objective of this study was to describe the unique cause and clinical…
