Purpose Since the term orthorexia nervosa (ON) was coined from the Greek (ὀρθός, right and ὄρεξις, appetite) in 1997 to describe an obsession with “correct” eating, it has been used worldwide without a consistent definition. Although multiple authors have proposed diagnostic criteria, and many theoretical papers have been published, no consensus de...

Purpose In recent years, there has been growing interest in pathologically healthful eating, often called orthorexia nervosa (ON). Much of the literature in this area has been about point prevalence of ON in particular populations, which range from less than 1% to nearly 90% depending on the study. Despite this interest, there has been no extensive...

Aim In some cases, detrimental consequences on health are generated by self-imposed dietary rules intended to promote health. The pursuit of an “extreme dietary purity” due to an exaggerated focus on food may lead to a disordered eating behavior called “orthorexia nervosa” (ON). ON raises a growing interest, but at present there is no universally s...

Purpose: Orthorexia nervosa, or pathological dieting based on being "healthy," has been of growing interest. Clinical data are limited to less than a half-dozen case studies reporting instances of medical problems due to healthful eating. However, more than a dozen studies using a measure to identify orthorexia, the ORTO-15, report very high preva...

Introduction: The psychiatric Consult Liaison (CL) service in a general hospital setting provides a fertile environment for psychological service and training. There is significant potential for future growth, both in terms of including psychology on CL teams and in training future psychologists in this setting, due to increased health care demands...

“Orthorexia nervosa” is a term introduced to describe disordered eating behavior with a pathological obsession for healthy nutrition which can result in insufficient diets and serious medical problems. Validated diagnostic criteria have not yet been developed for orthorexia nervosa and as a result, it has not been well studied. In this case, a pati...

There is growing evidence for the similarity between eating disorders and substance use disorders with respect to etiology, neurobiology, clinical presentation, and effective treatments. In addition, they each have features commonly seen in impulse control disorders, which are also frequently characterized as behavioral addictions. Therefore, it is...

Although there have been a limited number of case reports of human bilateral hippocampal injury, none of these have addressed the impact of such injuries on medical decision making capacity. The authors present a case of an elderly man with discrete bilateral hippocampal injury. As a result of his injury, the patient was hopelessly “lost in the pre...

Brown tree snakes, Boiga irregularis, exhibited an elevated frequency of jaw rubbing when a small quantity of petroleum jelly was placed on their lips. Jaw rubbing has the effect of removing foreign material from the lips, and it represents a behavior that cleans and maintains a particular part of the body surface. Although few such behaviors have...

Purpose This paper aims to systematically compare the textbook‐based criminal justice and psychological literatures on detecting deception in field settings to determine the accuracy of the criminal justice literature in this area. Design/methodology/approach A total of 18 criminal justice textbooks covering detecting deception were systematically...

We present the case of a 55-year-old homeless male who presented with penis and scrotal maggot infestation secondary to genital self-mutilation. The patient gave a history consistent with gender identity disorder and indicated that he was intoxicated during the event. The patient had no history of psychosis. He sought medical attention only after h...

To determine the safety and effectiveness of fentanyl administration for prehospital pain management. This was a retrospective chart review of patients transported by ambulance during 2002-2003 who were administered fentanyl citrate in an out-of-hospital setting. Pre- and post-pain-management data were abstracted, including vital signs, verbal nume...

In July 2007, a suburban Denver ambulance began a routine "psych transfer" of a 36-year-old woman from a hospital to a psychiatric facility. During transport, the woman leapt from the moving ambulance onto a busy interstate. She later died of her injuries. Similar incidents are by no means uncommon. In September 2007, another psych transfer ended i...

To perform an initial screening study of methicillin-resistant Staphylococcus aureus (MRSA) contamination in an ambulance fleet. This was a cross-sectional study of MRSA contamination in an ambulance fleet operating in the western United States in June 2006. Five specific areas within each of 21 ambulances (n = 105) were tested for MRSA contaminati...

Helicopters have become a major part of the modern trauma care system and are frequently used to transport patients from the scene of their injury to a trauma center. While early studies reported decreased mortality for trauma patients transported by helicopters when compared with those transported by ground ambulances, more recent research has que...

Those who write about the police have generally neglected the informal ways police officers handle situations involving troublesome persons. Troublesome persons, including homeless and mentally disturbed people, prostitutes, juveniles, and people under the influence of alcohol or drugs, are not necessarily best handled by arrest. In fact the recent...

To be a first step in determining whether emergency medicine technician (EMT)-Basics are capable of using a protocol that allows for selective immobilization of the cervical spine. Such protocols are coming into use at an advanced life support level and could be beneficial when used by basic life support providers. A convenience sample of participa...

Concerns that patients presenting for neuropsychological assessment may not be putting forth maximum effort during testing has prompted the development of measures designed to detect malingering and incomplete effort. Two of these measures are the Computerized Assessment of Response Bias-97 (CARB-97) and Word Memory Test (WMT). Despite widespread u...

Brown treesnakes (Boiga irregularis) responded with more tongue flicks to blood (from rabbits, rats, and mice) than to water. When rat blood was centrifuged at 3,500 rpm for 5 min, separating serum from cellular residue, snakes responded strongly to serum but not to cellular residue.

Twenty-eight subjects from a university's subject pool were paired on sex, age, severity, and type of stressful or traumatic incident. One subject in each pair was selected to receive EMDR; the experimental partner spent the same amount of time receiving a visual (non-movement) placebo. Subjective units of discomfort (SUD) scores and physiological...

Ten specimens ofBoiga irregularis were presented with clean or bloody tampons. The latter were used by women during menses. Trial duration was 60 sec, intertrial interval was 24 hr, and the dependent variable was rate of tongue flicking (a measure of chemosensory investigation). Bloody tampons elicited significantly more tongue flicking than did co...
