BackgroundPanic disorder is associated with neuroendocrinological abnormalities, some of which overlap with those seen in major depression. To date, there has been little assessment of the role of cholinergic mechanisms in this disorder.MethodSixteen patients with DSM–III–R panic disorder and an age and gender-matched comparison group were administered 120 mg of the acetylcholinesterase inhibitor pyridostigmine. Growth hormone (GH) responses over a three-hour period were monitored.ResultsMean ΔGH, the difference between basal and the maximum pyridostigmine levels, was significantly greater in patients with panic disorder than in the comparison group.ConclusionsThis may reflect increased cholinergic responsivity in panic disorder.

Objectives: Retrospective recall of dissociative symptoms has been found to mediate the association between childhood abuse and deliberate self-harm (DSH) in later life. To disentangle the effect of recall bias, we tested whether dissociation symptoms ascertained during an acute DSH presentation mediates this link. Method: All participants with DSH were recruited during emergency presentation. Seventy-one individuals aged 11–17 years with overdose (OD) and/or self-injury (SI) participated in semi-structured interviews and psychiatric assessment to measure abuse and dissociation. An age- and gender-matched comparison group of 42 non-psychiatric patients admitted to the same service were also assessed. Results: The DSH groups reported significantly higher levels of abuse and dissociation compared to comparison group. Dissociation significantly mediated the association between abuse and DSH. Of the four dissociation subtypes, ‘depersonalisation’ was the primary mediator. Adolescents with chronic patterns of DSH and the ‘OD + SI’ self-harm type reported more severe dissociation. Conclusion: Exposure to abuse significantly increased the risk of DSH in adolescence. This association was mediated by dissociation. Our findings suggest a possible dose–response relationship between dissociation with DSH chronicity and the ‘OD + SI’ self-harm type, implicating the importance of evaluating dissociation and depersonalisation symptoms as well as abuse exposure in DSH management.

The role of children in Merovingian society has long been downplayed, and the study of their graves and bones has long been neglected. However, during the past fifteen years, archaeologists have shown growing interest in the place of children in Merovingian society. Nonetheless, this research has not been without challenges linked to the nature of the biological and material remains. Recent analysis of 315 children’s graves from four Merovingian cemeteries in northern Gaul (sixth to seventh centuries) allows us to understand the modalities of burial ritual for children. A new method for classifying children into social age groups shows that the type, quality, quantity, and diversity of grave goods were directly correlated with the age of the deceased. They increased from the age of eight and particularly around the time of puberty. This study discusses the role of age and gender in the construction and expression of social identity during childhood in the Merovingian period.

Current design manuals provide guidance on how to design exit ramps to facilitate driving operations and minimize the incidence of crashes. They also suggest that interchanges should be built along straight roadway sections. These criteria may prove ineffective in situations where there is no alternative to terminals being located along curved motorway segments. The paper investigates driving behavior along parallel deceleration curved terminals, with attention paid to the difference in impact between terminals having a curvature which is the same sign as the motorway segment (i.e., continue design), and those having an opposite curvature (i.e., reverse design). A driving simulation study was set up to collect longitudinal and transversal driver behavioral data in response to experimental factor variations. Forty-eight drivers were stratified on the basis of age and gender, and asked to drive along three randomly assigned circuits with off-ramps obtained by combining experimental factors such as motorway mainline curve radius (2 values), terminal length (3), curve direction (2), and traffic conditions (2). The motorway radius was found to be significant for drivers’ preferred speed when approaching the terminal. Terminal length and traffic volume do not have a significant impact on either longitudinal or transversal driver outputs. However, the effect of curve direction was found to be significant, notably for reverse terminals which do not compel drivers to select appropriate speeds and lane change positions. This terminal type can give rise to critical driving situations that should be considered at the design stage to facilitate the adoption of appropriate safety countermeasures.

AbstractCT colonography has emerged as the investigation of choice for suspected colorectal cancer in patients when a colonoscopy in incomplete, is deemed high risk or is declined because of patient preference. Unlike a traditional colonoscopy, it frequently reveals extracolonic as well as colonic findings. Our study aimed to determine the prevalence, characteristics and potential significance of extracolonic findings on CT colonography within our own institution. A retrospective review was performed of 502 patients who underwent CT colonography in our institution between January 1, 2010 and January 4, 2015. Of 502 patients, 60.63% had at least one extracolonic finding. This was close to other similar-sized studies (Kumar et al. Radiology 236(2):519–526, 2005). However, our rate of E4 findings was significantly higher than that reported in larger studies at 5.3%(Pooler et al. AJR 206:313–318, 2016). The difference may be explained by our combination of symptomatic/screening patients or by the age and gender distribution of our population. Our study lends support to the hypothesis that CT colonography may be particularly useful in identifying clinically significant extracolonic findings in symptomatic patients. CT colonography may allow early identification of extracolonic malignancies and life-threatening conditions such as an abdominal aortic aneurysm at a preclinical stage when they are amenable to medical or surgical intervention. However, extracolonic findings may also result in unnecessary investigations for subsequently benign findings.

Interpreting other people’s intentions during communication represents a remarkable challenge for children. Although many studies have examined children’s understanding of, for example, sarcasm, less is known about their interpretation. Using realistic audiovisual scenes, we invited 124 children between 8 and 12 years old to watch video clips of young adults using different speaker intentions. After watching each video clip, children answered questions about the characters and their beliefs, and the perceived friendliness of the speaker. Children’s responses reveal age and gender differences in the ability to interpret speaker belief and social intentions, especially for scenarios conveying teasing and prosocial lies. We found that the ability to infer speaker belief of prosocial lies and to interpret social intentions increases with age. Our results suggest that children at the age of 8 years already show adult-like abilities to understand literal statements, whereas the ability to infer specific social intentions, such as teasing and prosocial lies, is still developing between the age of 8 and 12 years. Moreover, girls performed better in classifying prosocial lies and sarcasm as insincere than boys. The outcomes expand our understanding of how children observe speaker intentions and suggest further research into the development of teasing and prosocial lie interpretation.
