Potential health risks of recreational fishing in new york city.

BACKGROUND: Fish in the rivers around New York City are contaminated with polychlorinated biphenyls (PCBs) that have been increasingly associated with neurodevelopmental abnormalities. The New York State Department of Health has recommended that the consumption of fish from the rivers around New York City not exceed one meal per month and that no pregnant women or children less than 15 years of age eat any fish from these waters. DESIGN/METHODS: We systematically surveyed anglers at Manhattan fishing sites over a 3-month period to estimate the exposure of anglers, children, and women of childbearing age to PCB-laden fish. RESULTS: One hundred sixty anglers completed the interview. Eighty percent of these anglers were unaware of any advisory to limit fish consumption in order to limit PCB exposure. Most anglers ate the fish they caught. Of the anglers who said that they took the fish home (72.5% of the total sample), 17.7% reported that children regularly eat the fish, and 15.4% reported that an individual had been pregnant while regularly eating the fish. CONCLUSION: Despite state advisories, New York City anglers report high rates of fish consumption by themselves, pregnant women, and children. Although determining the consequences of such consumption will require further study, this represents a worrisome environmental exposure.

Hemodynamic changes induced by recreational scuba diving.

OBJECTIVE: Cardiac changes induced by scuba diving were investigated using Doppler echocardiography. MATERIAL AND METHODS: Ten healthy scuba divers dove to a mean depth of 34.3 +/- 2.7 m of sea water (113 +/- 9 feet) and a mean duration of 25.3 +/- 3.5 min. RESULTS: One hour after the dive, microbubbles could be detected in the right-heart chambers of all subjects. Left atrial and left ventricular (LV) diameters significantly decreased after the dive. Cardiac output, assessed by aortic blood flow, remained unchanged. Heart rate increased and stroke volume (SV) decreased after the dive. LV filling was assessed on transmitral profile. An increase of the contribution of the atrial contraction to LV filling was observed. Right cavity diameters were unchanged, but an increase of the right ventricular/right atrial gradient pressure was found. CONCLUSION: The diving profile studied promotes a rather important bubble grade in all volunteers. A significantly reduced cardiac diameters and SV was found by our hemodynamic study 1 h after diving. Two factors can explain these results: low volemia secondary to immersion, and venous gas embolism induced by nitrogen desaturation. Consequently, restoration of the water balance of the body should be considered in the recovery process after diving.

Recreational scuba diving in Caribbean marine protected areas: do the users pay?

There are more than 200 marine protected areas (MPAs) in the Caribbean and Central America that contain coral reefs and are therefore theoretically attractive to scuba divers. One fifth of dive operators in 30 countries were surveyed for their use of MPAs: the majority are located within 20 km of at least one MPA and 46% conduct at least 80% of their diving within a MPA. An estimated 15 million dives take place outside of Florida each year, half of these occurring inside MPAs. Only 25% of MPAs containing coral reefs charge divers an entry or user fee, which is most usually USD 2-3 levied per dive or per diver. The revenue generated by these fees is estimated at USD 1-2 million annually, but the potential for generating income has not been fully realized. A significant contribution to the cost of regional conservation could be achieved if higher fees were applied more widely than at present.

[Recreation and child development: an approach in music and in nursing care].

The imaginary world is important for the comprehension and insertion of the child in her surrounding world. Being this way, the ludicrous nursing care arises, assuring an integral and careful assitance, where games, plays, songs, and dances are present to subsidize the care. Music and all its involving and instructing sonority must be highlighted, being its musicality inserted in her environment. The child establishes herself as to be for to interact with other and the world, being the playing necessary for her growth and development.

Design of living environments for nursing-home residents: increasing participation in recreation activities.

Nursing-home residents have frequently been characterized as unoccupied and disengaged. At the outset of the present study, most residents were to be found in their own rooms, not exhibiting gross motor behavior or social interaction, and not participating in appropriate activities. To modify residents' levels of participation with the environment, a manipulative area was provided in the lounge. Participation in the lounge averaged 20% on days when the activity was not available, but increased to a mean of 74% on days when equipment and materials were given and residents were prompted to participate. When prompts were withdrawn and materials were available only by request, mean participation fell to 25%. The findings demonstrate that manipulative activities can support a high level of participation with the environment, if residents are prompted to use equipment and materials.

Thermotolerant non-fecal source Klebsiella pneumoniae: validity of the fecal coliform test in recreational waters.

Wisconsin pulp and paper mill processing plants were evaluated for fecal coliform and total Klebsiella (i.e., thermotolerant and thermointolerant) bacterial concentrations. Using the standard fecal coliform test, up to 90 per cent of non-fecal source thermotolerant K. pneumoniae was falsely identified as fecal source bacteria. Since there is a lack of specificity in the currently used standard for fecal coliform evaluation, a more reliable health risk assessment for fecal coliform bacteria is recommended.

Central nervous system injuries in sport and recreation: a systematic review.

Many sports have been associated with a variety of neurological injuries affecting the central nervous system (CNS), with some injuries specific to that sport. A systematic review of sport-specific CNS injuries has not been attempted previously, and could assist in the understanding of morbidity and mortality associated with particular sporting activities, either professional or amateur. A systematic review of the literature was performed using PubMed (1965-2003) examining all known sports and a range of possible CNS injuries attributable to that sport. Numerous sporting activities (45) have associated CNS injuries as reported within the literature. The sports most commonly associated with CNS injuries are: football, boxing, hockey, use of a trampoline, and various winter activities. A number of sporting activities are associated with unique CNS injuries or injury-related diseases such as heat stroke in auto racing, vertebral artery dissection in the martial arts, and dementia pugilistica in boxing. Neurological injuries of the CNS due to sport comprise a wide collection of maladies that are important for the neurologist, neurosurgeon, orthopaedic surgeon, physiatrist, sports medicine doctor, athletic trainer and general physician to recognise.

Peripheral nervous system injuries in sport and recreation: a systematic review.

Many sports are associated with a variety of peripheral nervous system (PNS) injuries specific to that sport. A systematic review of sport-specific PNS injuries has not been attempted previously, and will assist in the understanding of morbidities and mortality associated with particular sporting activities, either professional or amateur. A systematic review of the literature using PubMed (1965-2003) was performed examining all known sports and a range of possible PNS injuries attributable to that sport. Numerous sporting activities (53) were found to have associated PNS injuries. The sports most commonly reported with injuries were football, hockey, soccer, baseball and winter activities. There are a number of sporting activities with injuries unique to the individual sport. This review should be of assistance for the neurologist, neurosurgeon, orthopaedic surgeon, physiatrist, sports medicine doctor, athletic trainer and general physician in contact with athletes possessing neurological injuries.

Density and spatial distribution of Ixodes pacificus (Acari: Ixodidae) in two recreational areas in north coastal California.

The density and distribution of Ixodes pacificus was assessed at 2 parks in north coastal California. The density of I. pacificus adults and nymphs varied significantly between years, trails, and sides of trails. Adult ticks occurred on vegetation along sun-exposed trails in January through March, their density (0-1.93 per 20 m) correlated with brush density, trail width, and presence of an uphill slope. Nymphs (0.06-5.10 per 20 m) occurred in leaf litter along shaded trails in May-July. Adult I. pacificus were rare at picnic sites (0.00-0.24 per 20 m), but nymphal densities (0.93-2.37 per 20 m) were comparable with those along some shaded trails. The prevalence of Borrelia burgdorferi in ticks (2.8% overall) did not differ significantly between locations, years, or stages. We conclude that the risk of acquiring Lyme disease in these sites is low, but varies among trails, seasons, and years.
