Treatment of plantar fasciitis.

Plantar fasciitis is a common cause of heel pain in adults. The disorder classically presents with pain that is particularly severe with the first few steps taken in the morning. In general, plantar fasciitis is a self-limited condition. However, symptoms usually resolve more quickly when the interval between the onset of symptoms and the onset of treatment is shorter. Many treatment options exist, including rest, stretching, strengthening, change of shoes, arch supports, orthotics, night splints, anti-inflammatory agents and surgery. Usually, plantar fasciitis can be treated successfully by tailoring treatment to an individual's risk factors and preferences.

Benzodiazepines in the intensive care unit.

The effects of BZ drugs result from interaction at the GABAA receptor within the CNS, producing anxiolysis, hypnosis, and amnesia in a dose-dependent fashion. These sedative effects are best titrated to reproducible clinical endpoints, using scoring systems such as the Ramsay scale. All BZs exhibit similar pharmacologic effects, but the important differences in pharmacokinetics and pharmacodynamics should be recognized to use these drugs safely and effectively within the ICU. Diazepam is the classic anxiolytic, amnestic, and sedative agent, but the presence of long-acting active metabolites that depend on the kidneys for elimination limits its use in many ICU patients. Lorazepam is the most potent BZ used in the ICU; it has stable pharmacokinetics and relatively low cost. This drug is best reserved for situations in which rapid onset is not essential and long-term sedation is anticipated. Midazolam has the shortest t1/2 of the commonly used BZs, generates few active metabolites, and is water soluble at physiologic pH. Thus, it is well suited for continuous infusion in the ICU, and the recent introduction of generic formulations of midazolam has decreased the drug-acquisition cost for many hospitals. Optimal sedation for ICU patients often requires BZ and concomitant therapy with drugs such as haloperidol, dexmedetomidine, opioids, and so forth, to reduce untoward side effects and, perhaps, overall drug costs. Flumazenil, a specific BZ antagonist, can be used for diagnostic or therapeutic reversal of BZ agonists when appropriate. Most experienced intensivists recommend an individualized approach to sedation and titration of anxiolysis to maximize efficacy, minimize side effects, and optimize cost effectiveness in the ICU. New CNS monitors of the EEG, such as the BIS or entropy EEG monitors, may refine titration algorithms further in the near future.

Snowboarding injuries.

Snowboarding is a popular winter sport that involves riding a single board down a ski slope or on a half-pipe snow ramp. Compared with injuries resulting from traditional alpine skiing, snowboarding injuries occur more frequently in the upper extremities and ankles and less frequently in the knees. Different types of snowboard equipment, rider stance and snowboarding activity tend to result in different types of injury. Snowboarder's ankle, a fracture of the lateral talus, must be considered in a snowboarder with a "severe ankle sprain" that has not responded to treatment. Risk of injury may be lowered by using protective equipment, such as a helmet and wrist guards.

Medical coverage of high school football in Wisconsin in 1997.

OBJECTIVE: The goals of this study were to assess the health care available to Wisconsin high school football players and to assess high schools' compliance with safety requirements of the Wisconsin Interscholastic Athletic Association (WIAA). DESIGN: The design was a cross-sectional survey-based study. SETTING: The setting consisted of WIAA high schools. PARTICIPANTS: Athletic directors of WIAA high school football programs participated in the survey. MAIN OUTCOME MEASURES: The main outcome measures were the prevalence of medical coverage by physicians, certified athletic trainers, and ambulance personnel at football games and practice and the prevalence of compliance with WIAA requirements. RESULTS: Seventy-seven percent (302/392) of surveys were returned. Thirty-six percent of schools had a designated team physician. Eighty-seven percent had a trainer, and 86% were certified athletic trainers (Athletic Trainer Certified, ATC). At practice and scrimmage, 79% had an ambulance available or on call, 52% had a trainer present, and 28% had a physician on call. At football games, 71% had an ambulance, 67% a certified athletic trainer, 48% an emergency medical technician, and 45% a physician present. Regarding WIAA requirements, 9% had no accessible phone, 27% had no written emergency plan of action, 92% had gloves, and 92% had blood spill kits. Larger schools had better compliance with WIAA requirements than did smaller schools. CONCLUSION: Health care coverage was provided mainly by trainers and ambulance personnel, although physicians were routinely present at almost half of all games. Failure to comply with WIAA medical coverage requirements was not infrequent. This study forms the basis for an informational intervention, providing an opportunity to correct deficits.

In-line skating: use of protective equipment, falling patterns, and injuries.

OBJECTIVE: To determine the use of protective equipment, reasons for nonuse of protective equipment, and patterns of injury, falls, and stopping techniques of recreational in-line skaters. DESIGN: Survey. PARTICIPANTS: 313 in-line recreational skaters observed skating in the parks, on bicycle trails, and on parkways in Milwaukee, Wisconsin and Columbus, Ohio were asked to participate in a short survey in 1995. MAIN OUTCOME MEASUREMENTS: The frequency of in-line skater use of protective equipment, reasons for nonuse, patterns of injury, and patterns of falls. RESULTS: Protective equipment was worn most of the time in the following proportions of skaters [95% confidence interval in brackets]: wrist guards (51%) [44.7%-58.1%]; knee pads (36%) [29.3%-42.5%]; elbow pads (15%) [8.4%-22.8%]; and helmets (15%) [8.0%-22.0%]. Reasons cited for not using protective equipment included lack of perceived need (47.3%), discomfort (37.5%), cost (15.9%), and undesirable appearance (15.2%). Stopping techniques included skating off into the grass (14.6%) [11.8%-17.4%] and voluntarily falling (3.5%) [2.1%-4.9%]. Causes of involuntary falls included spontaneous loss of balance (32.9%) [28.9%-36.9%], hitting rocks or other small objects (17.3%) [14.4%-20.2%], uneven pavement (17%) [14.2%-19.8%], and failure to stop (11.3%) [8.4%-14.2%]. Site of initial impact after falling included the hands and wrists (44.6%) [38.3%-50.9%], the knees (19.6%) [16.4%-22.8%], and the buttocks region (17.2%) [14.3%-20.1%]. Injuries had occurred in 26% of the skaters; 14% of injuries were fractures. CONCLUSIONS: In-line skaters often do not wear protective equipment because they believe it is not necessary. Recent studies have suggested, however, that protective equipment does prevent injuries. Physicians should counsel their patients who are in-line skaters to use protective equipment.

Acute pulmonary edema caused by ingestion of hydrochlorothiazide.

Hydrochlorothiazide is one of most commonly prescribed antihypertensive diuretics. In this case, an allergic reaction to hydrochlorothiazide resulted in severe pulmonary edema. Hydrochlorothiazide, one of the most commonly prescribed drugs, is a diuretic which is usually well tolerated. Common side effects include dizziness, weakness, fatigue, and cramps. These side effects are usually caused by fluid and electrolyte imbalances. Acute pulmonary edema, first reported by Steinberg in 1968, is a rare but potentially life-threatening allergic reaction to hydrochlorothiazide. This case illustrates many of the typical presenting features of the reaction.

Serial sevens: not the most effective test of mental status in high school athletes.

OBJECTIVE: To evaluate the ability of uninjured high school athletes to pass three mental status tests that are commonly used on the sidelines for the evaluation of concussions: the serial sevens test, the serial threes test, and recitation of months of year in reverse order (MOYR). PARTICIPANTS: High school student athletes in grades 9, 10, 11, and 12 having sports preparticipation physical examinations. The initial study tested 522 consecutive athletes. The follow-up study tested 109 consecutive athletes. INTERVENTION: The athletes of the initial group were asked to perform a serial sevens test, followed by a serial threes test, and finally to recite the MOYR. The second group was asked to perform the same tests in a random order. MAIN OUTCOME MEASURES: Participants were given 1-min time limits for each test, with passing defined as either 7 consecutive correct iterations or 11 correct with one mistake. RESULTS: For the initial group, 51.3% successfully performed serial sevens, 78.7% successfully performed serial threes, and 89.5% successfully recited the MOYR. For the second group, 52.7% successfully performed serial sevens, 78.1% successfully performed serial threes, and 88.9% successfully recited the MOYR. The pass rates were significantly different for both groups. The pass rates were similar for both sexes, all grade levels, and all sports in both test groups. Participants, both overall and in all subgroups, failed serial sevens more often than serial threes and MOYR (p < 0.001 for the initial group; p < 0.0001 for the second group). They failed serial threes more often than MOYR (p < 0.001 for the initial group; p < 0.01 for the second group). CONCLUSIONS: The percentage of uninjured high school athletes successfully completing serial sevens is too low to make the test useful for evaluation of concussion; the test lacks specificity. The percentage of athletes passing the MOYR was greatest, perhaps making this a better sideline test than the traditional serial sevens test. However, testing needs to be done in injured athletes before clinical application can be recommended.

Temperature monitoring.

Central temperature is usually tightly regulated in human beings. Anesthesia alters the normal thermoregulatory controls of the body. Intraoperatively, mild degrees of hypothermia may provide some cerebral protection. However, the risk of organ dysfunction and shivering require that the anesthesiologist be prepared to treat severe hypothermia. Appropriate measures such as warning the operating room and using forced air blankets can prevent both intraoperative hypothermia and postoperative shivering. The use of temperature measurement is not limited to the operative and immediate recovery periods. Anesthesiologists practicing in intensive care units and in pain clinics use temperature monitoring as a diagnostic tool in a variety of situations.

Establishing a high-school-based training room clinic.

Being a team physician can be a time-consuming commitment. The team physician is responsible for all aspects of the athlete's care and has the final say in all medical matters related to athletic participation. Primary care physicians are well suited to be team physicians. The training room is an outstanding way to increase physician availability to adolescents and underserved population. Setting up a training room must be planned in advance, including funding, supplies and liability. Most legal problems can be avoided with a contract and proper documentation. The school-based training room provides the physician with an excellent opportunity for community service and can be a very rewarding experience.

In-line skating. An observational study of protective equipment used by skaters.

OBJECTIVES: To determine the frequency and patterns of use of the various types of protective equipment by in-line skaters and to determine if use of protective equipment was associated with the age, sex, group composition, or expertise of the skater. DESIGN: A total of 1548 in-line skaters were observed during a 3-month period in Milwaukee, Wis. Identification and protective equipment data were recorded and analyzed by chi 2 tests with Pearson's correlation coefficient. RESULTS: Overall, 491 skaters (31.7%) wore no protective gear. Wrist guards were worn by 999 skaters (64.5%). Helmets were worn by only 40 skaters (2.6%). Overall, adolescent males, children, and advanced skaters were the least likely to be observed wearing protective equipment. CONCLUSIONS: Protective equipment is underused by many in-line skaters. Educating in-line skaters about the value of wearing protective equipment, as recommended by equipment manufacturers, may help reduce the severity or incidence of skating injuries.

Clinical evaluation of continuous noninvasive blood pressure monitoring: accuracy and tracking capabilities.

A continuous, noninvasive device for blood pressure measurement using pulse transit time has been recently introduced. We compared blood pressure measurement determined using this device with simultaneous invasive blood pressure measurements in 35 patients undergoing general endotracheal anesthesia. Data were analyzed for accuracy and tracking ability of the noninvasive technique, and for frequency of unavailable pressure measurements by each method. A total of 25,133 measurements of systolic pressure, diastolic pressure, and mean arterial pressure (MAP) by each method were collected for comparison from 35 patients. Accuracy was expressed by reporting mean bias (invasive pressure minus noninvasive pressure) and limits of agreement between the two measurements. After correction for the offset found when measuring invasive and oscillometric methods of arterial pressure measurement, the mean biases for systolic, diastolic, and mean pressures by the pulse wave method were -0.37 mm Hg, -0.01 mm Hg, and -0.05 mm Hg, respectively (p < 0.001). The limits of agreement were: -29.0 to 28.2 mm Hg, -14.9 to 14.8 mm Hg, and -19.1 to 19.0 mm Hg, respectively (95% confidence intervals). When blood pressure measured invasively changed over time by more than 10 mm Hg, the noninvasive technique accurately tracked the direction of change 67% of the time. During the entire study, 3.2% of the invasive measurements were unavailable and 12.9% of the noninvasive measurements were unavailable. The continuous noninvasive monitoring technique is not of sufficient accuracy to replace direct invasive measurement of arterial blood pressure, owing to relatively wide limits of agreement between the two methods.(ABSTRACT TRUNCATED AT 250 WORDS)
