Extreme rituals in a BDSM context: the physiological and psychological effects of the 'Dance of Souls'.

Participation in extreme rituals (e.g., fire-walking, body-piercing) has been documented throughout history. Motivations for such physically intense activities include religious devotion, sensation-seeking and social bonding. The present study aims to explore an extreme ritual within the context of bondage/discipline, dominance/submission and sadism/masochism (BDSM): the 'Dance of Souls', a 160-person ritual involving temporary piercings with weights or hooks attached and dancing to music provided by drummers. Through hormonal assays, behavioural observations and questionnaires administered before, during and after the Dance, we examine the physiological and psychological effects of the Dance, and the themes of spirituality, connectedness, transformation, release and community reported by dancers. From before to during the Dance, participants showed increases in physiological stress (measured by the hormone cortisol), self-reported sexual arousal, self-other overlap and decreases in psychological stress and negative affect. Results suggest that this group of BDSM practitioners engage in the Dance for a variety of reasons, including experiencing spirituality, deepening interpersonal connections, reducing stress and achieving altered states of consciousness.

Ectrodactyly ectodermal dysplasia clefting (EEC) syndrome: a rare cause of congenital lacrimal anomalies.

A 9-year-old girl with a medical history significant for ectrodactyly ectodermal dysplasia clefting (EEC) syndrome was referred for evaluation of congenital left-sided epiphora. The patient had undergone successful right external dacryocystorhinostomy at age 5 to treat congenital right-sided epiphora. On examination, several ocular anomalies were noted, including absence of the upper eyelid puncta, absence of the left inferior punctum, a left lacrimal fistula opening at the left caruncle, increased left tear lake, bilateral hypoplastic meibomian glands, mild conjunctival injection, and thin eyelid cilia and brow hair. Systemic findings included cleft lip and palate status-post repair, ectrodactyly of the hands and feet, adontia and microdontia, a pointed nose, and lightly pigmented, dry hair and skin. The patient underwent examination under anesthesia and left conjunctivodacryocystorhinostomy with insertion of a Jones tube with resolution of lacrimation postoperatively. To the authors' knowledge, this is the second report detailing management of congenital lacrimal anomalies in EEC syndrome, and the first describing management of punctal atresia with conjunctivodacryocystorhinostomy and Jones tube placement.

Social support attenuates presyncopal reactions to blood donation.

BACKGROUND: The experience of unpleasant blood donation reactions (e.g., dizziness, nausea, and fainting) has been linked to negative attitudes about donation and decreased likelihood of repeat donation. Consequently, interventions to reduce the adverse effects of blood donation are important and likely to increase donor retention. Based on laboratory studies suggesting that social support attenuates both physical and psychological responses to stress, the present study hypothesized that the presence of a supportive person during the donation process may help reduce reactions. STUDY DESIGN AND METHODS: A final sample of 65 men and women with fewer than three prior donations was randomly assigned to either donate blood as usual or donate with a supportive research assistant. Donors in the support condition were accompanied throughout the donation process by a female research assistant who provided encouragement, made reassuring remarks, and engaged in small talk. Donors in both conditions completed a series of questions to assess anxiety, experience of prefaint reactions, and willingness to provide a future donation. RESULTS: Compared to standard donation controls, donors in the social support condition reported fewer prefaint reactions (F(1,61) = 9.15, p = 0.004, eta(2)= 0.13) and greater likelihood of donating again within the next year (Z =-1.70, p < 0.05, one-tailed). CONCLUSION: Relatively novice donors report reduced reactions to blood donation when accompanied by a supportive individual, suggesting that social support may be a simple strategy to enhance the donation experience and possibly increase donor retention.

Altered States of Consciousness during an Extreme Ritual.

Extreme rituals (body-piercing, fire-walking, etc.) are anecdotally associated with altered states of consciousness-subjective alterations of ordinary mental functioning (Ward, 1984)-but empirical evidence of altered states using both direct and indirect measures during extreme rituals in naturalistic settings is limited. Participants in the "Dance of Souls", a 3.5-hour event during which participants received temporary piercings with hooks or weights attached to the piercings and danced to music provided by drummers, responded to measures of two altered states of consciousness. Participants also completed measures of positive and negative affect, salivary cortisol (a hormone associated with stress), self-reported stress, sexual arousal, and intimacy. Both pierced participants (pierced dancers) and non-pierced participants (piercers, piercing assistants, observers, drummers, and event leaders) showed evidence of altered states aligned with transient hypofrontality (Dietrich, 2003; measured with a Stroop test) and flow (Csikszentmihalyi, 1990; Csikszentmihalyi & Csikszentmihalyi, 1990; measured with the Flow State Scale). Both pierced and non-pierced participants also reported decreases in negative affect and psychological stress and increases in intimacy from before to after the ritual. Pierced and non-pierced participants showed different physiological reactions, however, with pierced participants showing increases in cortisol and non-pierced participants showing decreases from before to during the ritual. Overall, the ritual appeared to induce different physiological effects but similar psychological effects in focal ritual participants (i.e., pierced dancers) and in participants adopting other roles.

Predonation water ingestion attenuates negative reactions to blood donation.

BACKGROUND: Novice blood donors are at increased risk for unpleasant blood donation-related symptoms (e.g., dizziness, weakness, and lightheadedness), and the experience of such symptoms can contribute to a decreased likelihood of repeat donation. Recent laboratory studies suggest that water ingestion produces hemodynamic effects that may be sufficient to reduce risk of syncope and related reactions during blood donation. STUDY DESIGN AND METHODS: Male and female volunteers were randomly assigned to ingest either 500 or 0 mL of water 30 minutes before donating blood for the first time. In addition, bioimpedance analysis was used to assess predonation chronic hydration levels in all donors. Immediately after donation, participants completed the Blood Donation Reactions Inventory to assess subjective experience of negative physiologic reactions. RESULTS: Analysis of Blood Donation Reactions Inventory scores revealed that predonation water ingestion was associated with a 47-percent reduction of total donation-related symptoms (F [1,79]= 11.81, p = 0.001). Chronic hydration status was not related to reported reactions. CONCLUSION: Novice blood donors responded positively to predonation water consumption, and they were able to consume 500 mL in less than 5 minutes. Results of the present study suggests that predonation water ingestion may be a simple and cost-effective strategy to enhance the donation experience and possibly increase donor retention.

Dysregulation of gene expression in the R6/2 model of polyglutamine disease: parallel changes in muscle and brain.

Previous analyses of gene expression in a mouse model of Huntington's disease (R6/2) indicated that an N-terminal fragment of mutant huntingtin causes downregulation of striatal signaling genes and particularly those normally induced by cAMP and retinoic acid. The present study expands the regional and temporal scope of this previous work by assessing whether similar changes occur in other brain regions affected in Huntington's disease and other polyglutamine diseases and by discerning whether gene expression changes precede the appearance of disease signs. Oligonucleotide microarrays were employed to survey the expression of approximately 11,000 mRNAs in the cerebral cortex, cerebellum and striatum of symptomatic R6/2 mice. The number and nature of gene expression changes were similar among these three regions, influenced as expected by regional differences in baseline gene expression. Time-course studies revealed that mRNA changes could only reliably be detected after 4 weeks of age, coincident with development of early pathologic and behavioral changes in these animals. In addition, we discovered that skeletal muscle is also a target of polyglutamine-related perturbations in gene expression, showing changes in mRNAs that are dysregulated in brain and also muscle-specific mRNAs.

Polyglutamine and transcription: gene expression changes shared by DRPLA and Huntington's disease mouse models reveal context-independent effects.

Recent evidence indicates that transcriptional abnormalities may play an important role in the pathophysiology of polyglutamine diseases. In the present study, we have explored the extent to which polyglutamine-related changes in gene expression may be independent of protein context by comparing mouse models of dentatorubral-pallidoluysian atrophy (DRPLA) and Huntington's disease (HD). Microarray gene expression profiling was conducted in mice of the same background strain in which the same promoter was employed to direct the expression of full-length atrophin-1 or partial huntingtin transproteins (At-65Q or N171-82Q mice). A large number of overlapping gene expression changes were observed in the cerebella of At-65Q and N171-82Q mice. Six of the gene expression changes common to both huntingtin and atrophin-1 transgenic mice were also observed in the cerebella of mouse models expressing full-length mutant ataxin-7 or the androgen receptor. These results demonstrate that some of the gene expression effects of expanded polyglutamine proteins occur independently of protein context.

Increased huntingtin protein length reduces the number of polyglutamine-induced gene expression changes in mouse models of Huntington's disease.

Both transcriptional dysregulation and proteolysis of mutant huntingtin (htt) are postulated to be important components of Huntington's disease (HD) pathogenesis. In previous studies, we demonstrated that transgenic mice that express short mutant htt fragments containing 171 or fewer N-terminal residues (R6/2 and N171-82Q mice) recapitulate many of the mRNA changes observed in human HD brain. To examine whether htt protein length influences the ability of its expanded polyglutamine domain to alter gene expression, we conducted mRNA profiling analyses of mice that express an extended N-terminal fragment (HD46, HD100; 964 amino acids) or full-length (YAC72; 3144 amino acids) mutant htt transprotein. Oligonucleotide microarray analyses of HD46 and YAC72 mice identified fewer differentially expressed mRNAs than were seen in transgenic mice expressing short N-terminal mutant htt fragments. Histologic analyses also detected limited changes in these mice (small decreases in adenosine A2a receptor mRNA and dopamine D2 receptor binding in HD100 animals; small increases in dopamine D1 receptor binding in HD46 and HD100 mice). Neither HD46 nor YAC72 mice exhibited altered mRNA levels similar to those observed previously in R6/2 mice, N171-82Q mice or human HD patients. These findings suggest that htt protein length influences the ability of an expanded polyglutamine domain to alter gene expression. Furthermore, our findings suggest that short N-terminal fragments of mutant htt might be responsible for the gene expression alterations observed in human HD brain.
