Snapping iliopsoas tendon in a recreational athlete: a case report.

OBJECTIVE: To describe the evaluation, diagnosis, and conservative treatment of a 31-year-old female recreational athlete with a snapping iliopsoas tendon. BACKGROUND: The iliopsoas tendon has been implicated as an inflamed structure in this unique form of snapping hip. Hip pain, limitation of motion, or both may severely restrict vocational and recreational function and activities of daily living. DIFFERENTIAL DIAGNOSIS: Left snapping hip syndrome secondary to the iliopsoas tendon or the iliotibial band. TREATMENT: The treatment goal was to restore the athlete's pain-free, functional abilities. The primary focus of the treatment program was stretching of the left hip flexors. The patient demonstrated reduced pain and improved function following a 4-week stretching program and was fully functional and symptom free at 6 months. UNIQUENESS: Snapping hip syndrome is a clinical entity that may be described as hip pain associated with an audible snap of the hip during motion. The most common and well-known cause of this syndrome involves the snapping of the iliotibial band over the greater trochanter. A less common cause is the snapping of the iliopsoas tendon over the iliopectineal eminence. CONCLUSIONS: Understanding the anatomy and function of the iliopsoas tendon and related structures provides a basis for evaluation and treatment of this unique problem.

The absence of hearing loss in otologically asymptomatic recreational scuba divers.

We undertook a retrospective cohort study of 16 experienced recreational scuba divers and 16 matched non-diver controls to determine the prevalence of hearing loss and, if present, the likely causes of this loss. Each subject was required to be aged 55 years or less and to have no history or likelihood of hearing loss. An audiologist, blinded to each subject's group status, undertook all examinations. There were no significant differences in group demographics. All divers were highly experienced (median number of dives 725). Comparison of mean hearing thresholds (range 250-8000 Hz) revealed no significant differences between divers and non-divers for both air and bone conduction studies. The only exception was at 6000 Hz where the air conduction threshold was significantly higher in divers than in non-divers (p = 0.03). However, there were no significant differences in Pure Tone and High Frequency averages. We conclude that experienced recreational scuba divers do not have elevated hearing threshold levels overall when compared to non-diver controls. This conclusion differs from that of investigators who have examined the hearing of experienced professional divers. Further investigation is indicated to further investigate this discrepancy and to determine whether the apparent hearing loss among the divers at 6000Hz was an isolated departure from normal hearing thresholds or, in fact, the result of diving.

PFGE analysis of enterococci isolates from recreational and drinking water in Greece.

Biotyping and DNA fingerprinting by pulsed-field gel electrophoresis were applied to a collection of enterococci recovered from recreational and drinking water, in order to identify possible genetic relationships. Clinical strains of hospital origin were compared to the environmental isolates. A total of 104 enterococci were isolated from 128 recreational water (94 marine and 34 river water) and 470 drinking water supplies (440 municipal and 30 natural spring water samples). Sixty-two isolates were characterised as Enterococcus faecium recovered from all sources, 32 E. faecalis (from all sources), 4 E. durans (from marine, river and municipal water), 4 E. gallinarum (from marine water) and 2 E. avium (from marine and municipal water). Biotypes, determined with API20Strep, among E. faecium were correlated with certain environmental sources, while antibiotypes, determined with Etest, did not reveal any relationship to the sample origin. Even though genetic diversity was observed among the studied strains, common clonal types were also identified in different sources, suggesting a possible common origin of the enterococci. Cluster analysis revealed a genetic relationship between certain environmental E. faecium and clinical strains.

Pathogenic marine vibrio species in selected Nova Scotian recreational coastal waters.

Seven heavily frequented coastal recreation sites serving Metropolitan Halifax and Dartmouth were investigated to determine the numbers and species of pathogenic marine vibrios (PMV) present. Seawater, mussels and sea gull feces were cultured using quantitative methods and the effects of temperature and fecal pollution noted. Emergency rooms serving the sites under surveillance were monitored for PMV-related infections. All 11 recognized species of pathogenic marine vibrios were recovered from the 7 sites. Estuarine sites yielded a greater variety of species and greater numbers of PMV than non-estuarine sites. Culture of hand washings after immersion in seawater did not demonstrate contamination of skin by PMV. We did not demonstrate any cases of PMV infection associated with the 7 surveillance sites. PMV contamination of marine recreational waters does not frequently result in superficial infections.

Assessment of the abuse liability of buspirone in recreational sedative users.

The abuse potential of buspirone, a new dopaminergic antianxiety drug, was evaluated by assessing its subjective effects in standard (10 mg) and high (40 mg) doses. These were compared with methaqualone (300 mg), diazepam (20 mg and 10 mg), and placebo in 24 casual recreational sedative users. Addiction Research Center Inventory scales measuring euphoria, sedation, dysphoria, and abuse liability were used as dependent measures. Groups of subjects received all treatments in randomized order in six weekly 4-hour sessions. Compared to placebo, methaqualone caused elevated scores on euphoria, physical sedation, and abuse liability scales compared to placebo, while 40 mg buspirone caused increased physical sedation, increased physical and mental dysphoria, and lower abuse liability scores. Overall, buspirone at 40 mg appeared unlikely to be reinforcing to recreational illicit drug users; the 10 mg dose was not discriminable from placebo or 10 mg diazepam. Diazepam at 20 mg showed some euphoriant effect compared to placebo.

Death during recreational exercise in the State of Rhode Island.

From January 1, 1975 to May 1, 1982, 81 individuals died during or immediately after recreational exercise in the State of Rhode Island. Deaths occurred during a variety of activities, but the majority of deaths occurred during golf (23%), jogging (20%), and swimming (11%). Atherosclerotic coronary heart disease (ASHD) was the presumed cause of 88% of the deaths, primarily in subjects over age 29 with known cardiac abnormalities. Only 7% of ASHD victims had no relevant medical history or ASHD risk factors and were considered healthy by their families and physicians. In contrast, deaths in young subjects were rarely associated with ASHD or prior knowledge of cardiovascular disease. Only six deaths in individuals aged 29 or younger occurred during the study period. These deaths were associated with congenital cardiovascular disease (N = 2), valvular heart disease (N = 1), hemorrhagic gastritis (N = 1), idiopathic myocardial hypertrophy (N = 1), and hypertrophic cardiomyopathy with ASHD (N = 1). A diagnosis was made before death only in the individual with valvular disease. We conclude that death during recreational exercise is predominantly due to ASHD and occurs in men with recognized ASHD risk factors, relevant medical histories, or known disease. Death during exercise in asymptomatic subjects is rare and relatively more frequent in younger age groups.

Reorganization of ascending 5-HT axon projections in animals previously exposed to the recreational drug (+/-)3,4-methylenedioxymethamphetamine (MDMA, "ecstasy").

The recreational drug (+/)3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") is a methamphetamine derivative that selectively destroys central 5-HT axons and axon terminals in animals and, possibly, humans. The fate of 5-HT neurons following MDMA injury is uncertain. In particular, while it is known that central 5-HT axons can undergo regenerative sprouting after MDMA injury, it has not been determined whether they reestablish the original innervation pattern. To address this question, the present studies examined 5-HT innervation patterns in animals lesioned with MDMA 12-18 months previously. Both rodents (rats) and nonhuman primates (squirrel monkeys) were examined, since there is indication that serotonergic recovery after MDMA injury may be species dependent. 5-HT axon projections were studied neurochemically, autoradiographically and immunocytochemically. In both rodents and nonhuman primates previously lesioned with MDMA, substantial serotonergic axonal sprouting was observed. However, in a few rats and in most squirrel monkeys, the reinnervation pattern was highly abnormal: distant targets (e.g., dorsal neocortex) remained denervated, while some proximal targets (e.g., amygdala, hypothalamus) were reinnervated or hyperinnervated. Although the specific determinants of axonal recovery after MDMA injury remain to be identified, it appears that axons which initially sustain more severe damage, are longer, or are more highly arborized have low probability of recovering. The observation that some brain regions remain denervated, while others are reinnervated or hyperinnervated suggests that, under some circumstances, MDMA injury can lead to a lasting reorganization of ascending 5-HT axon projections. Such lasting changes in brain innervation, documented here in MDMA-treated animals, may have implications for humans using MDMA recreationally.

The natural history of untreated anterior cruciate tears in recreational athletes.

A followup study was performed to elucidate the natural course of acutely torn anterior cruciate ligaments in recreational athletes. Fifty-six consecutive patients had arthroscopy within 2 weeks of their initial injuries; however, no surgery was done on the torn anterior cruciate ligament. Twenty anterior cruciate ligament and medial collateral ligament combined ruptures occurred. Patient ages ranged from 14 to 50 years old (mean, 28.9 years). Followup periods ranged from 2 to 10 years (mean, 5 years 6 months). Through examination with the KT-1000 arthrometer, side-to-side differences of anterior translation of the tibia of > or = 3 mm in 72% patients at reexamination were seen. Eight of 46 patients had mild osteoarthritic changes of Grade 1 visible on radiographs, but only 1 patient reported knee trouble. Nine patients had repeat injuries, 3 of whom had late reconstructions and 4 late meniscectomies. Functional scores averaged 95 +/- 6.5 points. Activity scores averaged 4.8 +/- 1.6 points. Operative management for the medial structure did not improve the stability better than nonoperative management. Anterior translation and functional scores of patients with medial meniscectomies showed significant differences from those of other patients. Anterior cruciate ligament reconstruction for recreational athletes should be considered when the patients have reparable meniscal tears, and meniscal repairs should be performed simultaneously.

Recreational drugs. Current trends in the 90s.

Recreational drug use continues to be prevalent in many social settings. These drugs are alleged to enhance sociability and liberate inhibitions, allowing the user to experience feelings of euphoria. This article reviews recreational drugs that have gained notoriety in the 1990s including gamma-hydroxybutyrate (GHB), flunitrazepam, and amphetamine analogues such as 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA), and 3,4-methylenedioxyethylamphetamine (MDEA). Topics discussed include history, drug use and misuse, clinical presentation and treatment, and laboratory analysis.

Risk factors for basal cell carcinoma in a Mediterranean population: role of recreational sun exposure early in life.

OBJECTIVE: To investigate the role of pigmentary traits, different patterns of sun exposure, artificial sources of UV radiation, and lifestyle-related factors on the risk of basal cell carcinoma (BCC) in a Mediterranean population from central-southern Italy. DESIGN: Hospital-based case-control study. SETTING: A referral dermatological hospital in Rome, Italy. PATIENTS: A convenience sample of 166 case patients with histologically confirmed BCC and 158 cancer-free control subjects with minor dermatological conditions observed between March 1995 and June 1997. RESULTS: In the multivariate analysis, the mean number of weeks per year spent at the beach before the age of 20 years was significantly associated with BCC. A dose-response trend was found for subjects who had spent 3 to 4 (odds ratio, 1.8; 95% confidence interval, 0.8-4.4), 5 to 8 (odds ratio, 3.7; 95% confidence interval, 1.5-9.0), or more than 8 (odds ratio, 4.5; 95% confidence interval, 1.9-10.5) weeks per year at the beach (P =.01 for trend). There was a significant association with the presence of actinic keratoses or solar lentigines, whereas no effect was found for skin type, history of sunburns, exposure to nonsolar UV radiation, and lifestyle-related habits such as cigarette smoking, alcohol consumption, and coffee drinking. Subjects reporting a family history of skin cancer had an extremely increased risk of BCC. CONCLUSION: The definite association with recreational sun exposure during childhood and adolescence and the strong relation with family history of skin cancer suggest that genetic predisposition and peculiar exposure patterns to UV radiation are key independent risk factors for the development of BCC in a southern European population.

Recreational physical activity and the risk of breast cancer in postmenopausal women: the Women's Health Initiative Cohort Study.

CONTEXT: Women who are physically active have a decreased risk for breast cancer, but the types, amounts, and timing of activity needed are unknown. OBJECTIVE: To prospectively examine the association between current and past recreational physical activity and incidence of breast cancer in postmenopausal women. DESIGN, SETTING, AND PATIENTS: Prospective cohort study in 74 171 women aged 50 to 79 years who were recruited by 40 US clinical centers from 1993 through 1998. MAIN OUTCOME MEASURE: Incident invasive and in situ breast cancer. RESULTS: We documented 1780 newly diagnosed cases of breast cancer over a mean follow-up of 4.7 years. Compared with less active women, women who engaged in regular strenuous physical activity at age 35 years had a 14% decreased risk of breast cancer (relative risk [RR], 0.86; 95% confidence interval [CI], 0.78-0.95). Similar but attenuated findings were observed for strenuous physical activity at ages 18 years and 50 years. An increasing total current physical activity score was associated with a reduced risk for breast cancer (P =.03 for trend). Women who engaged in the equivalent of 1.25 to 2.5 hours per week of brisk walking had an 18% decreased risk of breast cancer (RR, 0.82; 95% CI, 0.68-0.97) compared with inactive women. Slightly greater reduction in risk was observed for women who engaged in the equivalent of 10 hours or more per week of brisk walking. The effect of exercise was most pronounced in women in the lowest tertile of body mass index (BMI) (<24.1), but also was observed for women in the middle tertile of BMI (24.1-28.4). CONCLUSIONS: These data suggest that increased physical activity is associated with reduced risk for breast cancer in postmenopausal women, longer duration provides most benefit, and that such activity need not be strenuous.

Youthful habits of work and recreation and later cancer among physicians.

Scores on seven factors derived from a Habits of Work and Recreation Survey administered to 1,038 white male medical students 17 to 35 years ago were used to compare students who subsequently developed some form of major cancer with those who did not. With the Type I error rate controlled through use of multivariate analysis of variance and age and smoking ruled out as possible confounding variables, the two groups were significantly differentiated, primarily in terms of intellectual interests--cancer cases having fewer. Students at or below the overall mean on the intellectual interests measure were more than three times as likely to develop cancer as were students with scores above the mean. In this population, the results appear interpretable in terms of the stamina concept, in which few intellectual interests may reflect an absence of stamina and spontaneity and/or failure to meet subcultural expectations--factors possibly associated with increased cancer risk.

Field measurement of dermal soil loadings in occupational and recreational activities.

Risks associated with dermal exposure to contaminated soil are not well-characterized, but nevertheless must be estimated to define endpoints for remedial strategies. Among the parameters contributing to the uncertainty of these estimates is soil adherence to skin. Pre- and postactivity soil loadings have been obtained from hands, forearms, lower legs, faces, and/or feet of volunteers engaged in various occupational and recreational activities. These data are distinguished from other sources of estimates of soil adherence by the manner of their collection. Soil loads were obtained directly from multiple body parts before and after uncontrived exposure scenarios. Data presented for the first time here supplement prior results and roughly double the available data base. This expanded data base provides a useful perspective on types of behavior likely to lead to soil contact falling within general classes of activity (e.g., background, low, moderate, or high contact). Prior conclusions supported by the additional data include the following: (1) post-activity loadings are typically higher than preactivity levels, demonstrating that exposure is episodic; (2) hand loadings are dependent upon class of activity; (3) hand loadings generally provide conservative estimates of loadings on nonhand body parts within activity classes; and (4) hand loadings do not provide conservative estimates of nonhand loadings across activity classes. Finally quantitative estimates of relative loads on unclothed nonhand body parts are presented.

Identification of sport fish consumption patterns in families of recreational anglers through factor analysis.

This paper reports on the identification of sport fish consumption patterns in angler families through the factor analysis technique. New York State recreational anglers and their spouses or partners were surveyed in 1991 about their consumption of Lake Ontario and Lake Erie sport fish. Respondents were surveyed again in 1997 to report the number of sport fish consumed by their children aged 5-10 years. Parental report revealed that 60% of children had consumed at least one sport fish meal over their lifetime. Anglers', partners', and children's variables were entered into three separate factor analysis models to assess consumption patterns. Factors for anglers and partners accounted for 65 and 59% of variance in consumption scores, respectively. Factors dealing with trout and salmon consumption accounted for the most variance. Children's factors accounted for 82% of variance in consumption scores, showing separation in relation to type of fish, body of water, and age at consumption. Children's factors were then used as dependent measures of separate multiple regression runs in which parental factors were entered stepwise as predictors. Significant associations between parental and children's factors were noted, suggesting that sport fish consumption patterns in parents are predictive of similar consumption patterns in children. Results suggest that sport fish consumption advisories do not fully prevent consumption of contaminated sport fish during childhood. Therefore, risk communicators may need to modify the current strategy of informing anglers and their families about sport fish consumption recommendations.

Access rights for outdoor recreation in New Zealand: some lessons for open country in England and Wales.

Access opportunities for outdoor recreation in New Zealand and England and Wales are classified according to their conformity with collective, citizenship or exclusion rights and their degrees of permanence. Alternative criteria for the apportionment of access rights are considered in the context of this classification. Different criteria for rights apportionment are found to be appropriate according to different circumstances in the context of pluralist provision. Policy developments in New Zealand are compared with those in England. After 150 years of a dominance of collective rights in New Zealand current policy is shifting provision towards exclusionary rights. In England, there is a policy shift in the other direction, towards collective rights. Lessons for the development of collective rights in England are drawn from the New Zealand experience in relation to styles of governance, public preferences, public cost, insurance liability and the potential of markets.

Impact of pain on recreational activities of nursing home residents.

The high prevalence of pain in older adults in nursing homes and long-term care institutions is a challenging problem. Nursing home residents were questioned to evaluate whether pain might be an obstacle to their active participation in recreational activities, especially physical activities. This study shows that the intensity and daily experience of pain are both obstacles to participation in physical activities, especially in the oldest patients. The findings also show that participation is linked to the autonomy of the patient; more information about the benefits of physical activity, and coordinating efforts in this area are needed in order to help the elderly preserve their autonomy and quality of life.

Explaining human settlement patterns in a recreational lake district: Vilas County, Wisconsin, USA.

Lakeshore development in Vilas County, northern Wisconsin (USA) is heterogeneous, ranging from lakes that are surrounded by homes and commercial establishments to lakes that have no buildings on their shorelines. Development in this recreational area has increased, and since the 1960s over half of new homes have been built on the lakeshore. We examined building density around lakes in relationship to 11 variables, including in-lake, shoreline, and social characteristics. Buildings in many parts of northern Wisconsin tend to be concentrated around shorelines; in Vilas County 61% of all medium-sized buildings (our proxy for residential development) on private land were < or =100 m of a lake. The probability of development on a lake was largely related to lake surface area, with larger, more accessible lakes showing a higher probability of development. Building density along shorelines varied with travel cost, lake surface area, presence of wetlands, and extent of public land ownership. Building density was greater on larger, more accessible lakes that were surrounded by forest (as opposed to wetlands) and public lands. Gaining a more precise understanding of human settlement patterns can help direct planning and resource protection efforts to lakes most likely to experience future development.

Tourist perceptions of degradation caused by coastal nature-based recreation.

Tourist perceptions of environmental degradation caused by nature-based tourism activities in a coastal environment were determined in the Central Coast Region of Western Australia. Structured surveys were administered to 702 visitors over two peak seasons. Visitors were required to indicate their perceptions on a Likert-type scale. Activities assessed were swimming, boating, fishing, diving and snorkelling, (wind)surfing, sandboarding, four-wheel driving, (bush)walking, camping, horseriding and sightseeing. Tourists had significantly variable demographic characteristics over two seasons and participated in different activities. However, perception of environmental degradation of individual activities did not vary significantly between seasons, except for fishing, four-wheel driving and sandboarding. The age, origin and level of education of visitors had more effect on perceptions than gender or income group. Participation in an activity affected perceptions only for those who went fishing, sandboarding, four-wheel driving and sightseeing. Visitor perceptions were comparable to 'real' impacts documented in the recreation ecology literature. The results of this research indicate a need for improved visitor education and interpretation facilities.
