"Saturday night fever": ecstasy related problems in a London accident and emergency department.

OBJECTIVES: To report on the extent and nature of acute MDMA (ecstasy) related problems presenting to a large London hospital's accident and emergency (A&E) department. METHOD: The computerised attendance records for all patients attending the A&E department over a 15 month period were retrospectively screened. Potential cases thus identified had their case notes systematically reviewed to confirm the history of MDMA use and to extract other relevant data. RESULTS: Forty eight consecutive MDMA related cases were identified. All were in the 15-30 year age group with the majority presenting in the early hours at weekends and having consumed the drug at a night club. The mean number of tablets consumed was two and almost 40% had taken MDMA before. Polydrug use was common with half of the sample having concurrently taken another illicit substance--most commonly other stimulants (amphetamines and cocaine). A wide range of adverse clinical features was found. The most common symptoms were vague and non-specific such as feeling strange or unwell, however many patients had collapsed or lost consciousness. The most common signs elicited were related to sympathetic overactivity, agitation/disturbed behaviour, and increased temperature. The more serious complications of delirium, seizures, and profound unconsciousness (coma) were commoner when MDMA was used in combination with other substances. CONCLUSIONS: For young adults presenting late at night at weekends and exhibiting symptoms of sympathetic overactivity, disturbed behaviour, and increased temperature ("Saturday night fever") the use of stimulant dance drugs especially MDMA should be suspected. As MDMA use does not appear to occur in isolation, the clinical picture is likely to be complicated by multiple rather than single drug ingestion. This poses increased diagnostic and management challenges for A&E staff who typically represent the front line response to dance drug related problems.

The Sufi, his headdress and its significance.

Etymologically Sufi, as an Arabic word, means woolen-clad. This is unsuitable in designating a devotee who tries to have union with God. When the word is taken to Chinese it means (my) master-and-father, my Guru. There are at least nine more words used in addressing the Sufi or speaking of him, all of Chinese origin. This leaves no word specially used for the sufi which is not derived from Chinese. Next comes a rite special to the sufis, it is whirling-dancing. It has no precedence in traditional Islam. On the contrary "Dancing in ancient China was a powerful means of seeking divine will, and producing ecstasy for calling down spirits from the invisible word." Thus sufism would be an adaptation from Chinese Shamanism. The headdress, rather than the dress covering the body, is special to the sufis; it is a long hat made to resemble the male generative organ. In ancient times this organ was sanctified and, as sacred object, its emblem formed the headdress of male and female deities. Even sages were buried with emblem of the male organ on their heads. The earlier form of Hindu Trinity was called Trai-Linga-Ishwara, where Linga literally means the male organ but semantically connotes creative power. To understand creation man had projected Birth as Creation when the male organ of reproduction was sublimated as power of creation. The prehistoric word was Chhiu, meaning phallus. This was pronounced as Shiu or Shew and later became Shiva, who was Phallus-god. In Greece Hermes was Phallus-god. With Shiva there was the Trinity Trai-Linga-Ishwara; Hermes was correspondingly called Tris-Majestis. The headdress, originally formed to resemble the male organ of reproduction underwent modifications. It grew in length while the top, from being round became flat. In this form it could be used without a cloth wrapped round to support it on the head. This was again unique and used only by the Sufis. Its past took it to the emblem of male generative organ but in all stages represented creative power.

Self-reported psychopathology in polydrug users.

There is a large body of work investigating concurrent associations between polysubstance use and psychopathology, but much of this work has either pre-dated or failed to account for the complex and culturally specific patterns of contemporary drug use. In particular, attendees of dance music events report a greater drug history than their peers and engage in a unique lifestyle. To further investigate the consequences of this type of drug use, 100 subjects who regularly attended dance music events were administered a battery of self-report psychiatric symptom scales. This battery contained the Anxiety Sensitivity Index, the Beck Anxiety Inventory (BAI), the Center for Epidemiologic Studies Depression scale (CES-D), the Dissociative Experiences Scale, the Padua Inventory Revised and additional questions about substance use. Our study population included abstainers and drug users with a wide history of use. We demonstrated strong associations between use of many different drugs, suggesting that polydrug use is the norm in this type of population. We found weak, but statistically significant, correlations between use of alcohol (p < 0.05), amphetamine (p < 0.01) and ecstasy (p < 0.01) with self-reported score on the BAI. There were also positive associations between dissociative symptomatology and the use of amphetamine (p < 0.05) and cocaine (p < 0.05). Furthermore, weekly unit intake of alcohol positively correlated with score on the CES-D (p < 0.05). As polydrug use was the norm in this sample, we performed regression analysis to investigate the contribution of multiple drug use on self-report. This showed that weekly use of alcohol, and frequency of use of amyl nitrate and cigarettes were significant predictors of BAI score. However, the majority of subjects reported being unworried by these symptoms, which may represent a lack of self-awareness, or acceptance of them as the subacute effects of substance use. It remains to be determined at what point adverse effects of drug use begin to interfere with day-to-day life.

Physical activity attitudes, preferences, and practices in African American, Hispanic, and Caucasian girls.

Physical activity levels in girls decline dramatically during adolescence, most profoundly among minorities. To explore ethnic and racial variation in attitudes toward physical activity, semistructured interviews (n = 80) and physical activity checklists (n = 130) are conducted with African American, Hispanic, and Caucasian middle school girls in six locations across the United States. Girls from all groups have similar perceptions of the benefits of physical activity, with staying in shape as the most important. Girls have similar negative perceptions of physical activity, including getting hurt, sweating, aggressive players, and embarrassment. Chores, running or jogging, exercises, and dance are common activities for girls regardless of ethnicity. Basketball, swimming, running, and dance are commonly cited favorite activities, although there are slight differences between ethnic groups. The results suggest that factors other than ethnicity contribute to girls' physical activity preferences and that distinct interventions may not be needed for each ethnic group.

Lack of bone accretion and amenorrhea: evidence for a relative osteopenia in weight-bearing bones.

Bone mineral density (BMD) was studied in young exercising amenorrheic girls to determine if density was compromised and the change related to injury. Ninety-eight volunteers (professional ballet dancers and controls) were studied in a cross-sectional study. Dancers and controls were further subdivided into normally cycling and amenorrheic subjects. Amenorrhea significantly lowered bone density of the spine (P less than 0.0001), wrist (P less than 0.03), and metatarsal (P less than 0.01); effects on the wrist were eliminated by controlling for age while controlling for weight eliminated all effects of amenorrhea at three sites. BMD of the metatarsal, a weight-bearing bone, showed an interaction between amenorrhea and dancing (exercising) P less than 0.035); surprisingly, dancing was associated with a further lowering of bone density. This interaction was eliminated when controlling for age, but not when controlling for weight. With multiple comparisons of the groups, spine, wrist, and metatarsal bone density was significantly lower in amenorrheic dancers when compared to normal dancers (P less than 0.05), even when controlling for age and weight in the metatarsal (P less than 0.05), and age in the spine (P less than 0.05). Estradiol levels correlated with bone density of both the wrist and the spine (r = 0.25, r = 0.23, P less than 0.02). Metatarsal density correlated with estradiol levels only in the dancers (r = 0.34, P less than 0.02). The only variable found to correlate with the occurrence of stress fractures was age of menarche. This was also the only variable of 9 (BMD of the wrist, spine or foot, calories ingested and expended, amount of calcium ingested, involvement in high energy activity, age of menarche or presence of amenorrhea) to predict stress fractures. Thus, BMD is significantly affected by the presence of amenorrhea but the effects are generally weight dependent. The compensatory increase in bone density generally seen in stressed bones, such as the metatarsal in ballet dancers, is deficient in amenorrheic premenopausal women even when controlling for weight but this effect may be age and estrogen dependent. Bone mass may not accumulate in the same manner in adolescents as in the mature women, thus putting them at risk for injury.

Transmission of vibration across honeycombs and its detection by bee leg receptors

Vibration of the rims of open cells in a honeycomb, applied in the plane of the comb face, is transmitted across the comb. Attenuation or amplification of the vibratory signal depends on its frequency and on the type of comb. In general, framed combs, both large and small, strongly attenuate higher frequencies, whereas these are amplified in small open combs. The very poor transmission properties of the large framed combs used in commercial hives may explain the bees' habit of freeing an area of comb from the frame in those areas used for dancing. Extracellular electrical recordings from the leg of a honeybee detect large action potentials from receptors that monitor extension of the tibia on the femur. Measurements of threshold displacement amplitudes show these receptors to be sensitive to low frequencies. The amplification properties of unframed combs extend the range of these receptor systems to include frequencies that are emitted by the bee during its dance, namely the 15 Hz abdomen waggle and 250 Hz thorax vibration.

Inflammatory markers and exercise: differences related to exercise type.

PURPOSE: To examine the relationship between elevated inflammatory markers (CRP, fibrinogen, and white blood cell levels) and various forms of exercise for the adult U.S. population while controlling for factors that might influence the relationship. METHODS: An analysis of the adults age 17 and over who participated in the National Health and Nutrition Examination Survey (NHANES) III was conducted. The main goal of the analysis was to determine whether exercise type was associated with systemic markers of inflammation. Bivariate statistics using chi-square to evaluate different types of exercise according to the presence of elevated and nonelevated inflammatory markers was initially performed. In addition, multivariate models were constructed using each type of exercise activity as the predictor variable and each inflammatory marker as the dependent variable. RESULTS: A total of 4072 people were included in the analysis. In bivariate analyses, compared with nonexercisers in a specific exercise type, a significant lower likelihood of elevated inflammatory markers was found among regular participants in jogging, swimming, cycling, aerobic dancing, calisthenics, and weight lifting but not for gardening. After controlling for possible confounding factors including age, race, sex, body mass index, smoking, and health status in logistic regression analysis, only regular participants in jogging and aerobic dancing remained significantly less likely to have elevated cardiovascular markers. CONCLUSIONS: The results of this study indicate that some forms of physical activity are associated with a lower likelihood of elevation of inflammatory markers, although we cannot exclude the possibility that differences may be due to exercise intensity or duration. Future research should be directed toward further exploration of the effects of different types of exercise activity on inflammatory markers and the role of exercise in the prevention of cardiovascular disease.

Honeybee odometry: performance in varying natural terrain.

Recent studies have shown that honeybees flying through short, narrow tunnels with visually textured walls perform waggle dances that indicate a much greater flight distance than that actually flown. These studies suggest that the bee's "odometer" is driven by the optic flow (image motion) that is experienced during flight. One might therefore expect that, when bees fly to a food source through a varying outdoor landscape, their waggle dances would depend upon the nature of the terrain experienced en route. We trained honeybees to visit feeders positioned along two routes, each 580 m long. One route was exclusively over land. The other was initially over land, then over water and, finally, again over land. Flight over water resulted in a significantly flatter slope of the waggle-duration versus distance regression, compared to flight over land. The mean visual contrast of the scenes was significantly greater over land than over water. The results reveal that, in outdoor flight, the honeybee's odometer does not run at a constant rate; rather, the rate depends upon the properties of the terrain. The bee's perception of distance flown is therefore not absolute, but scene-dependent. These findings raise important and interesting questions about how these animals navigate reliably.

Energy expenditure of sedentary screen time compared with active screen time for children.

OBJECTIVE: We examined the effect of activity-enhancing screen devices on children's energy expenditure compared with performing the same activities while seated. Our hypothesis was that energy expenditure would be significantly greater when children played activity-promoting video games, compared with sedentary video games. METHODS: Energy expenditure was measured for 25 children aged 8 to 12 years, 15 of whom were lean, while they were watching television seated, playing a traditional video game seated, watching television while walking on a treadmill at 1.5 miles per hour, and playing activity-promoting video games. RESULTS: Watching television and playing video games while seated increased energy expenditure by 20 +/- 13% and 22 +/- 12% above resting values, respectively. When subjects were walking on the treadmill and watching television, energy expenditure increased by 138 +/- 40% over resting values. For the activity-promoting video games, energy expenditure increased by 108 +/- 40% with the EyeToy (Sony Computer Entertainment) and by 172 +/- 68% with Dance Dance Revolution Ultramix 2 (Konami Digital Entertainment). CONCLUSIONS: Energy expenditure more than doubles when sedentary screen time is converted to active screen time. Such interventions might be considered for obesity prevention and treatment.

Ecstasy (MDMA): effects and patterns of use reported by users in São Paulo.

OBJECTIVE: As there are no studies about the use of ecstasy in Brazil, our aim was to identify the effects and patterns of use of this substance among users in the city of São Paulo. METHODS: Subjects were recruited through the snowball technique. Fifty-two subjects of both genders who had been using ecstasy frequently and recently were interviewed. The instrument was a self-reported and anonymous questionnaire. RESULTS: The sample's mean age was 24 years, mostly composed by single, college graduated middle-class subjects. Among the interviewed users, 61.6% used ecstasy at least once per week and 50% of them took one pill per episode of use and 46% more than one. Drug taking was usually performed in company of several people (63%) in contexts related to night leisure, such as rave parties (78.8%), dancing clubs (69.2%) and parties (53.8%). Ecstasy pills were mainly purchased from friends or acquaintances in order to favor a dancing mood in those places. Most subjects used ecstasy associated to other psychoactive drugs (93.3%), mainly Cannabis, followed by tobacco and LSD. The effects attributed to ecstasy were mainly positive. DISCUSSION: The use of ecstasy in São Paulo has had a recreational pattern quite similar to those described in previous studies. The assessment of the use of ecstasy as positive also agrees with the findings of the literature.

Physiologic status at 1-year follow-up of obese women engaged in a supervised conditioning program.

A follow-up study was conducted to re-evaluate a group of obese middle-aged women (n = 13), eight of whom had completed an 18-wk supervised (3 d/wk) plus unsupervised (2 d/wk) conditioning intervention program (at least 90 min per day) as the exercise plus diet group; while five of the remainder served as the control group. Each session had included a 25- to 45-min jog/run at intensities between the heart rate (HR) corresponding to lactate threshold (LT) and that slightly above the HR @ LT. During 1 year following the program, the women participated in self-controlled training such as running, aerobic dancing, or jazz dancing 2.6 +/- 1.1 d/wk. Dietary intake averaged approximately 1736 +/- 152 kcal/d at the pre-treatment, 1404 +/- 124 kcal/d at the post-treatment, and 1645 +/- 147 kcal/d 1 year after the post-treatment. Interestingly however, oxygen uptake corresponding to LT (VO2 @ LT), maximal oxygen uptake (VO2max), weight, systolic blood pressure, and the ratio of high-density lipoprotein cholesterol to total cholesterol (HDLC/TC) observed 1 year after the post-treatment were significantly different from the original pre-treatment and/or mid-treatment values. For instance, the significant 42% increase (14.7 +/- 2.4----21.3 +/- 4.2 ml/kg/min) in VO2 @ LT and 18% increase (0.284 +/- 0.106----0.335 +/- 0.093) in HDLC/TC from the pre-test to post-test were maintained throughout the 1-year follow-up period, suggesting no detrimental effect either on a cardiorespiratory fitness factor or on an anti-atherogenic factor. These findings indicate that physiologic status of obese middle-aged women engaged in a conditioning intervention program may not regress to pre-treatment status for at least one year after completion; provided they continue to participate in a 2.6-d/wk self-controlled training program with dietary intake of 1600-1700 kcal/d. Another interesting finding was that significant relationships existed between individual changes (delta) in training frequency and individual changes (delta) in physiologic variables (i.e., delta VO2max, delta VO2 @ LT, delta WT, delta fat, and delta HDLC/TC) during the follow-up study. It is concluded that, although the improved physiologic status of obese women can be maintained fairly well during 1 year following the conditioning program; continuation of training (3 d/wk or more) should be critical, either supervised or self-controlled, for successful maintenance of lost weight (8.2 +/- 2.9 kg) and improved fitness.

Does trampolining and anaerobic physical fitness affect sleep?

The structure of nocturnal sleep of 16 volunteers, participating in the anaerobic sports of trampolining, dancing, and soccer, was monitored by means of polygraphic recordings. Since trampolining requires the acquisition of unfamiliar patterns of motor coordination, it can be considered as a special form of motor learning, whereas the acquisition of motor skills specific for dancing and soccer can be linked with motor patterns of normal biped locomotion. According to this view, an experimental group of 8 volunteers was formed; they participated in a training course of trampolining. In addition, a control group of 8 subjects was recruited, who engaged in one of the other two anaerobic sports. Subjects who had acquired new motor skills during a 13-wk. program in trampolining showed a statistically significant increase in REM-sleep. By contrast, the 8 subjects of the control group showed no considerable changes in REM-sleep. This suggests that efforts in acquiring new and complex motor patterns activate processes specifically involved in the generation of REM stage during nocturnal sleep.

Laterality effects for music perception among differentially talented adolescents.

To examine the comparative nature of laterality patterns for music perception among differentially talented adolescents, 138 right-handed subjects (56 boys, 82 girls) trained in music, mathematics, and dance, respectively, were tested on dichotic chords and dichotic melodies tasks. Analyses demonstrated that only the musically trained subjects displayed task-dependent ear asymmetry, that is, a left-ear advantage for dichotic chords and a right-ear advantage for dichotic melodies. The mathematically and dance-talented students displayed a left-ear bias for both tasks of music perception. A control dichotic speech task showed a right-ear bias for all talent groups. The findings speak to how sensory information is managed by the mental-processing systems of differentially talented students and how talent training plays a role in shaping ear asymmetry.

Beta-endorphin response to endurance exercise: relationship to exercise dependence.

Considerable research has shown significant increases in beta-endorphin levels after aerobic activity. These increases and their accompanying euphoric effect have been suggested as a possible psychophysiological mechanism underlying the exercise-dependence syndrome. The relationship between plasma beta-endorphin levels and a tendency towards exercise dependence, however, has not been established. To examine this relationship, 8 women trained in aerobic dance completed an exercise-dependence assessment prior to participation in a 45-min. session of continuous aerobic dance. Plasma beta-endorphin concentration was measured both prior to and following the aerobics routine. A Student t test for paired observations indicated that mean plasma beta-endorphin levels (+/- SE) were significantly higher after the aerobics routine (11.96 +/- 1.3 pg beta-EP.ml-1) than preexercise levels (8.62 +/- 1.4). However, beta-endorphin difference values (% change) were not significantly correlated with scores on the exercise-dependence survey. Those data suggest that scores on exercise dependence are not related to changes in plasma beta-endorphin levels after aerobic exercise.

Hyponatraemia and death after "ecstasy" ingestion.

A 15-year-old girl collapsed with respiratory arrest after taking "ecstasy" at a "dance party". She presented to hospital with hyponatraemia and cerebral oedema and later died. We postulate that ingestion of large amounts of water contributed to the hyponatraemia. Advice to those using ecstasy at dance parties should be modified to suggest moderate fluid intake only and to emphasise the need to seek prompt medical attention for non-resolving symptoms.

[Ecstasy and its "counterparts"].

RISK AWARENESS: Use of psychostimulants is spreading in France, particularly at "techno" dances. The generic term "ecstasy" covers a wide variety of molecules with variable formulations. The situation is a true public health problem, generally concerning very young subjects who must be informed of the risks involved. Knowledge of the chemical makeup of the products currently used is needed to provide valid information and reduce risks. CHEMICAL ANALYSIS: Two types of chemical analysis are used for rapid controls. A coloration test is used by the Rave mission implemented by "Médecins du Monde". More elaborate analysis methods are used to identify the active substances and quantify the compounds in the different "tablets". FINDINGS: Rapid controls give a means of quickly identifying samples containing methylenedioxyamphetamines and distinguishing them from other samples which may contain any number of substances with unknown toxicity. A precise analysis of 73 samples has shown highly variable compositions with 22% actually containing methylenedioxyamphetamines. PREVENTION: Precise analytical knowledge of the drugs circulating in "techno" dances has revealed the extreme danger of a large number of the substances used. A continuous control of ongoing consumption is required to correctly warn the users and reduce risk.

Doing or being?

The founder of Aikido, Morihei Ueshiba, would occasionally distill the essence of the art into three simple shapes--a circle, a square, and a triangle. These are three basic ways of dealing with what's coming at you. The square is the simplest. It is about, essentially, doing nothing. The saying here is from the old spiritual: "I shall not be moved." You meet the challenge head on. The triangle is about forward motion--attack, cutting right to the heart of what is coming at you, or cutting right past it to the space beyond. The circle is often the most interesting space. The circle is not about standing ground or cutting through. The circle is about dancing with whatever is headed your way. The real danger lies in being stuck in any one mode--perpetually intransigent, always flailing away in attack mode, or forever slip-sliding through one dance step after another. It is only when our response is embodied in who we are that we will have the power truly to lead other people.

"Humanities in medicine".

Progress in medicine and medical technology along with economic constraints have led to increasing structural change in the hospital sector over the past years. As a result of these changes, the social needs of the patients are in danger of being eclipsed by the requirements of the optimization of hospital processes. Cultural activities can be a meaningful way to offset such changes. They stimulate individuals, promote well-being and prompt discussion. Cultural activities in hospitals are directed at patients, hospital employees and people in the community. In Germany, the 'National Association for Culture and Health MediArt' founded in 1995 has been responsible for the UNESCO project "Art in Hospitals" 1988-1997. This paper provides a snapshot of German hospitals that have integrated cultural activities in an exemplary fashion. The activities include such events as 'international cultural days', 'theatre groups', 'dance workshops', 'clinclowns'. Participants include professionals, employees, patients and visitors from the community. The activities are organized by individuals and/or cultural departments created to act as 'health centres' for musical, theatrical, dance and plastic art events.
