Facing up to binge drinking: Reducing binge drinking in adolescent males

Objective: To evaluate the effectiveness of an oro-facial trauma-based brief intervention, designed to raise adolescent males’ awareness about the immediate dangers of binge drinking.
Design: Non-randomised controlled exploratory trial
Setting: Secondary level schools
Materials & Methods: Pre, post and follow up validated questionnaires were used to assess a variety of descriptive data and changes in behaviour. Sixty Year 12 students were recruited in the pilot study and 182 in the definitive study.
Intervention: A brief visual presentation containing salient information and anonymised photographs relating to oro-facial injuries.
Main Outcome Measures: Intention to binge drink.
Results: The majority of participants obtained alcohol from off-license or licensed premises. At the commencement of the study, 68% of the participants were regular drinkers. Whilst there was no change in drinking behaviour, the intervention group reported that it was significantly more likely (compared to the control group) that they would reduce their drinking to less than binge levels.
Conclusion: The intervention resulted in participants reporting a more negative attitude towards binge drinking and increased their intention to disengage from binge drinking.

RED COATS AND WILD BIRDS: MILITARY CULTURE AND ORNITHOLOGY ACROSS THE NINETEENTH-CENTURY BRITISH EMPIRE

“Red coats and wild birds: military culture and ornithology across the nineteenth-century British Empire” investigates the intersections between British military culture and the practices and ideas of ornithology, with a particular focus on the British Mediterranean. Considering that British officers often occupied several imperial sites over the course of their military careers, to what extent did their movements shape their ornithological knowledge and identities at “home” and abroad? How did British military naturalists perceive different local cultures (with different attitudes to hunting, birds, field science, etc.) and different local natures (different sets of birds and environments)? How can trans-imperial careers be written using not only textual sources (for example, biographies and personal correspondence) but also traces of material culture? In answering these questions, I centre my work on the Mediterranean region as a “colonial sea” in the production of hybrid identities and cultural practices, and the mingling of people, ideas, commodities, and migratory birds. I focus on the life geographies of four military officers: Thomas Wright Blakiston, Andrew Leith Adams, L. Howard Lloyd Irby, and Philip Savile Grey Reid. By the mid-nineteenth century, the Mediterranean region emerged as a crucial site for the security of the British “empire route” to India and South Asia, especially with the opening of the Suez Canal in 1869. Military stations served as trans-imperial sites, connecting Britain to India through the flow of military manpower, commodities, information, and bodily experiences across the empire. By using a “critical historical geopolitics of empire” to examine the material remnants of the “avian imperial archive,” I demonstrate how the practices and performances of British military field ornithology helped to: materialize the British Mediterranean as a moral “semi-tropical” place for the physical and cultural acclimatization of British officers en route to and from India; reinforce imperial presence in the region; and make “visible in new ways” the connectivity of North Africa to Europe through the geographical distribution of birds. I also highlight the ways in which the production of ornithological knowledge by army officers was entwined with forms of temperate martial masculinity.

Vasoactive intestinal polypeptide (VIP) and VPAC1 receptor in adult human dental pulp in relation to caries

Objective: To quantitatively measure VIP levels and to qualitatively study the distribution of VIP fibres and demonstrate the presence of the VPAC1 receptor in human dental pulp from carious and non-carious adult human teeth. Design: Dental pulp samples were collected from non-carious, moderately carious and grossly carious adult human teeth. VIP levels were determined using radioimmunoassay. The distribution of VIP fibres was studied using immunohistochemistry. The VPAC1 receptor protein expression was determined by Western blotting. Results: VIP levels were found to be significantly elevated in the dental pulp of moderately carious compared with non-carious (p = 0.0032) or grossly carious teeth (p = 0.0029). The distribution of VIP fibres was similar in non-carious and carious teeth, except that nerve bundles appeared thicker in the pulp samples from carious compared with non-carious teeth. Western blotting indicated that the VPAC1 receptor proteins were detected in similar levels in pooled dental pulp samples from both carious and non-carious teeth. Conclusion: It is concluded that quantitative changes in the levels of VIP in human dental pulp during the caries process and the expression of VPAC1 receptor proteins in membrane extracts from carious and non-carious teeth suggests a role for VIP in modulating pulpal health and disease. © 2006 Elsevier Ltd.

Caries-induced changes in the expression of pulpal neuropeptide Y

Recent evidence suggests that the sympathetic nervous system may have a role in modulating neurogenic inflammation and bone remodelling. Neuropeptide Y (NPY) is a well-characterized neuropeptide transmitter in the peripheral sympathetic nervous system. NPY is known to be present in human dental pulp; however, quantitative data on NPY levels in pulpal health and disease in an adult population remain to be determined. The aims of the current study were to assess, quantitatively, NPY levels by radioimmunoassay and confirm the distribution of NPY fibres by immunocytochemistry in carious and non-carious adult human pulp tissue. Our results suggest changes in the levels and distribution of NPY in human dental pulp during the caries process, with significantly higher levels of NPY in carious compared with non-carious adult human teeth. Within the carious samples studied, our finding, that NPY levels were significantly elevated in mild/moderate caries, concurs with the hypothesis that NPY could have a modulatory role in pulpal inflammation and in reparative dentine formation. © 2006 Eur J Oral Sci.

Personality analysis of patients complaining of sialorrhoea

BACKGROUND: Sialorrhoea, the symptom of apparent excessive secretion of saliva is a relatively uncommon complaint. Some authors consider that in the absence of clinical findings, then these patients have a psychiatric disorder masquerading as a physical illness. However, there is little evidence in the literature to support this conclusion and a detailed psychological assessment of this population has not previously been reported. METHODS: In total, 18 patients and 18 age- and sex-matched controls were studied. All had a history of a complaint of excess salivation in the absence of any oral mucosal or systemic abnormality. All patients completed an Eysenck Personality Questionnaire. RESULTS: There were no differences in the extroversion of psychoticism scores between the study and control group. However, the result showed significant increases in the neuroticism and Lie Scale score in the patient group. CONCLUSIONS: The overall results of this study indicate that the complaint of sialorrhoea in otherwise healthy individuals does not have an organic basis and suggest that sialorrhoea is associated with high levels of neuroticism and a tendency to dissimulate. © Blackwell Munksgaard 2006.
