Breathing out dental fear: A feasibility crossover study on the effectiveness of diaphragmatic breathing in children sitting on the dentist's chair.

BACKGROUND: Anxiety related to the dental context is a clinically significant challenge. In children, dental fear is often accompanied by disruptive and uncooperative behaviours that can render treatment difficult. Although techniques to reduce children's anxiety exist, many have not been formally evaluated. DESIGN: Diaphragmatic breathing has been shown to reduce fear and anxiety, but few investigations have evaluated whether it can reduce dental anxiety in children. This crossover study tested the effectiveness and feasibility of diaphragmatic breathing in twenty children undergoing dental care. RESULTS: Compared with the treatment as usual, such a simple technique had significant benefits on mood, self-reported pain and autonomic balance, thus reducing sympathetic activation. CONCLUSION: Diaphragmatic breathing is a low-cost, easy-to-implement technique suitable for daily dental practice, and is a promising tool for reducing negative effect and physiological distress in children with dental anxiety that results in more cooperative behaviours and reduced visit time.

The spectrum of adjustment disorders: too broad to be clinically helpful.

The clinical value of the current Diagnostic and Statistical Manual of Mental Disorders diagnosis of adjustment disorder is controversial. The aim of this article is to review the literature on adjustment disorder and to present suggestions for the improvement of this diagnostic category in future classification systems. The literature utilized for this review was retrieved by MEDLINE (1967 until May 2009) and was supplemented by a manual search of the literature. The analysis of the literature indicates that the diagnosis of adjustment disorder is not characterized by consistent clinical description and prognosis, adequate differentiation from other disorders, or specific psychometric and neurobiologic features. The spectrum of affective disturbances entailed by the diagnosis of adjustment disorder appears to be too broad. A major problem seems to lie in the fact that it is an exclusion diagnosis that overlaps with subthreshold manifestations of mood and anxiety disorders. More precise characterizations of stress-related disturbances are available.

Clinical assessment of allostatic load and clinimetric criteria.

The concept of allostasis emphasizes that healthy functioning requires continual adjustments to the internal physiological milieu. Allostatic load reflects the cumulative effects of stressful experiences in daily life. When the cost of chronic exposure to fluctuating or heightened neural or neuroendocrine responses exceeds the coping resources of an individual, allostatic overload ensues. So far these issues have been addressed only on pathophysiological terms that do not find application in clinical settings. However, several features that have been described in psychosomatic research may allow the assessment of allostatic load on clinical grounds. Clinimetric criteria for the determination of allostatic overload are suggested. They are based on: (a) the presence of a stressor exceeding individual coping skills, and (b) clinical manifestations of distress. They may provide specification to the fourth axis of DSM, may supplement the Diagnostic Criteria for Psychosomatic Research, and may help discriminate neuroendocrine patterns with important clinical and research implications. A state of allostatic overload is frequently associated with alterations in biological markers and calls for a close medical evaluation of the patient's condition. The ultimate goal is to be able to prevent or decrease the negative impact of excessive stress on health.

Use of the Diagnostic Criteria for Psychosomatic Research (DCPR) in a community sample.

The authors assessed the prevalence of Diagnostic Criteria for Psychosomatic Research (DCPR) clusters in a community sample and the association between these syndromes and psychosocial variables. A group of 347 consecutive subjects from the general population were administered the semistructured interview for DCPR and a self-rating scale (the Psychosocial Index). A DCPR syndrome was identified in 59% of subjects. These subjects showed more stress and distress and less well-being than those without a DCPR syndrome. Some DCPR syndromes (alexithymia, Type A behavior, irritable mood) are frequently encountered in a community sample and are associated with impairment in quality of life. Other syndromes (demoralization, persistent somatization) that have been frequently found in medically ill persons were uncommon in this general-population sample.
