[Bacteriological study of seawater for recreational use].

A study was conducted at the request of the authorities of the Municipality of Bahía Blanca city, in order to decide whether the sea-water of a swimming pool was suitable for recreational purposes. The characterization of the water was performed through bacteriological indicators and the following groups of bacteria were studied: marine and terrestrial viable aerobic heterotrophic bacteria; total coliforms; Escherichia coli and fluorescent Pseudomonads. Salinity, temperature and pH were registered together with meteorological parameters. In every case, the bacteriological values obtained were lower than those of the most strict international standards used worldwide for bathing waters. In this way, the particular dynamic processing of the water entering the swimming pool from Blanca Bay becomes important, since previous studies conducted on the water of its Principal Channel had yielded high bacteriological values which rendered it unsuitable for bathing. This work shows that in this tidal-flats system, extrapolation of results is not valid. These conditions will remain the same if other factors do not change in the tidal-flats that surround the swimming pool.

Recreational scuba diving injuries.

Because of the increasing popularity of recreational scuba diving, primary care physicians should be familiar with common diving injuries. One form of barotrauma, middle ear squeeze, is the most common diving injury. Other important diving injuries include inner ear barotrauma and pulmonary barotrauma. Arterial gas embolism, a potentially life-threatening form of pulmonary barotrauma, requires hyperbaric treatment. Decompression sickness is the result of bubble formation in body tissue. Symptoms of decompression sickness range from joint pain to neurologic or pulmonary problems. Recompression is the mainstay of treatment.

A comparison of exercise performance on bicycle and rowing ergometers in female master recreational rowers.

Limited information exists on the response to maximal exercise testing in female masters level recreational rowers. This study examined cardiorespiratory and physiologic responses to progressive, incremental exercise using a variable resistance rowing ergometer and a cycle ergometer in six experienced female masters level rowers. Maximal oxygen uptake (VO2 max:33.8 +/- 7.3, 33.5 +/- 6.6 ml.kg-1.min-1) and minute ventilation (VEmax: 86.1 +/- 9.6 l.min-1, 88.7 +/- 13.8 l.min-1) were similar during both tests (rower vs cycle). Maximal heart rates were significantly higher on the cycle ergometer (177 +/- 9 beats/min-1) compared to the rowing ergometer (173 +/- 11 beats/min-1), while peak power on the rowing ergometer (175 +/- 22 watts) was lower than the cycle ergometer (187 +/- 41 watts). Blood lactate levels taken 1 minute following exercise were similar on the rowing ergometer (10.5 +/- 1.7 mM/l) and cycle ergometer (11.8 +/- 1.5 mM/l) and indicated maximal effort was achieved in all subjects. Ventilatory threshold levels were significantly different on the rower (2.0 +/- 0.16) versus the cycle ergometer (1.9 +/- 0.18) (p = 0.38). These data suggest that the cycle and rowing ergometers yield relatively similar results when testing maximal exercise performance in this population.

Clinical and functional outcome of anterior cruciate ligament reconstruction in the recreational athlete over the age of 35.

This study examined the functional, objective, and subjective outcome of anterior cruciate ligament (ACL) reconstruction in recreational athletes > or = 35 years after a minimum of 2 years of follow-up. Patients > or = 35 years who underwent ACL reconstruction by a single surgeon were identified from our surgical database. Nineteen knees in 18 (62% follow-up) patients were available for review by an independent examiner. The patients underwent physical examination, radiographs, functional testing, isokinetic strength testing, and instrumented ligament arthrometer testing. All were seen at a minimum of 2 years of follow-up. The average age was 40 years. Five of 19 underwent reconstruction less than 1 month after injury, and the remainder underwent reconstruction for chronic injuries. All patients preoperatively had at least a grade 2 Lachman and a positive pivot shift noted on physical examination. After a minimum of 2 years of follow-up, 17 of 18 patients had a stable knee on objective testing, including a negative Lachman and pivot shift. Seventeen patients (94%) had < 3 mm side-to-side difference on maximum manual arthrometric testing. Only one patient had > 3 cm prone heel height difference, and all patients had > 125 degrees of flexion. Mean thigh circumference difference was 0.5 cm. Isokinetic testing demonstrated a mean 11%, 7%, and 4% quadriceps asymmetry at 60 degrees, 180 degrees, and 240 degrees/second, respectively. However, functional testing revealed only a mean 6% asymmetry on vertical jump, single leg hop, and timed 6 meter hop. Seventeen of 18 patients were satisfied with their results. The mean postoperative Lysholm Rating Scale score was 93. The mean Noyes Sports Activity Scale score was 86, improved from 31 preoperatively. Thirteen of 18 returned to their preinjury level of sports performance. These results indicate that ACL reconstruction in patients over the age of 35 has functional, objective, and subjective results comparable to those of a younger patient population.

Brain dopamine neurotoxicity in baboons treated with doses of methamphetamine comparable to those recreationally abused by humans: evidence from [11C]WIN-35,428 positron emission tomography studies and direct in vitro determinations.

The present study sought to determine whether doses of methamphetamine in the range of those used recreationally by humans produce brain dopamine (DA) neurotoxicity in baboons and to ascertain whether positron emission tomography (PET) imaging with the DA transporter (DAT) ligand [11C]WIN-35,428 ([11C]2beta-carbomethoxy-3beta-(4-fluorophenyl)-tropane) could be used to detect methamphetamine-induced DAT loss in living primates. Baboons were treated with saline (n = 3) or one of three doses of methamphetamine [0.5 mg/kg (n = 2); 1 mg/kg (n = 2); and 2 mg/kg (n = 3)], each of which was given intramuscularly four times at 2 hr intervals. PET studies were performed before and 2-3 weeks after methamphetamine treatment. After the final PET studies, animals were killed for direct neurochemical determination of brain DA axonal markers. PET-derived binding potential values, used to index striatal DAT density, were significantly decreased after methamphetamine, with larger decreases occurring after higher methamphetamine doses. Reductions in striatal DAT documented by PET were associated with decreases in DA, dihydroxyphenylacetic acid, and specific [3H]WIN-35,428 and [3H]DTBZ binding determined in vitro. Decreases in DAT detected with PET were highly correlated with decreases in specific [3H]WIN-35,428 binding determined in vitro in the caudate of the same animal (r = 0.77; p = 0.042). These results indicate that methamphetamine, at doses used by some humans, produces long-term reductions in brain DA axonal markers in baboons, and that it is possible to detect methamphetamine-induced DAT loss in living nonhuman primates by means of PET.

A new wellness center concept: integration of the physical therapy and the morale, welfare, and recreation departments.

This case study describes the implementation of a wellness center based on the integration of a Navy outpatient physical therapy department and a morale, welfare, and recreation cardiovascular center. The logistics and services provided are discussed. The productivity of the physical therapy department based on the monthly number of patient treatments is assessed. A statistically significant increase in patient visits of 38% above the previous year was noted. The newly established cardiovascular center averaged 1,500 client visits monthly. This unique collaboration appears to hold promise as an effective wellness center concept.

Knee injuries produced by recreational sports follow a different pattern than casual injuries.

Data was collected on 208 Chinese males who underwent knee arthroscopy following trauma in the period from January 1993 through December 1994. For the purpose of comparison and analysis, the patients were classified according to their sporting habits as sedentary patients, recreational athletes, or competitive athletes. There were no significant differences in age between the three groups (average age: 25.82 +/- 10.6; range: 12 to 73 years). A hemarthrosis was present in 122 patients, and an effusion in 35. The most common mechanism of injury was direct impact (105 patients), followed by a twisting injury (58 patients). The most common arthroscopic finding was an anterior cruciate ligament (ACL) tear (partial in-37 patients and complete in 43 patients). In both sedentary and athletic patients, a hemarthrosis was significantly associated with ACL and meniscal tears (p = 0.02). When comparing the pattern of arthroscopic pathology between sports and casual injuries, a significantly greater number of ACL tears (both complete and partial) were caused during sports activity (p = 0.032). Sports injuries also resulted in a significantly greater number of meniscal injuries (p = 0.028). However, sedentary patients suffered from a greater prevalence of tibial osteochondral fractures (10%) than did those in the sports group (5%) (p = 0.04).

[Common overuse knee-to-toes injuries in recreational exercise. Most cases are treatable in primary health care].

Although overuse injuries are common among recreational exercise-takers, in most cases they are treatable in primary care. It is important to evaluate both intrinsic and extrinsic aetiological factors underlying the development of overuse injuries. Treatment should always be focused on the aetiological factors, rather than solely on the symptoms. After an initial period of rest, a supervised rehabilitation programme, combined with correction of intrinsic and extrinsic factors, is the optimal treatment for most overuse syndromes. Surgery is only rarely necessary.

Breastfeeding and the use of recreational drugs--alcohol, caffeine, nicotine and marijuana.

This paper both reviews the current literature and explores anecdotal information as reported by Nursing Mothers' Breastfeeding Counsellors relating to breastfeeding and the use of alcohol, caffeine, nicotine and marijuana. All of these drugs do enter breastmilk to some extent and can have a detrimental effect on the production, volume, composition and ejection of breastmilk, as well as a direct adverse effect on the infant. Breastfeeding mothers should be encouraged to restrict their intake of these so-called recreational drugs. It is acknowledged that this is a particularly stressful period in a mother's life and that she may need additional support and practical suggestions to limit the exposure of these drugs to the infant.
