ABSTRACT: Mild traumatic brain injury, or concussion, is a common consequence of collisions, falls and other forms of contact in sports. Concussion may be defined as an acute trauma-induced alteration of mental function lasting fewer than 24 hours, with or without preceding loss of consciousness. The physician's responsibilities in assessing an athlete with concussion include determining the need for emergency intervention and offering guidance about the athlete's ability to return to play. Concussion may be complicated by cerebral edema related to the second impact syndrome, cumulative neuropsychologic deficits, intracranial bleeding or the postconcussion syndrome. The risk of complications is increased in athletes who prematurely return to play and in those with prolonged loss of consciousness or post-traumatic amnesia. An athlete with prolonged loss of consciousness or signs and symptoms that worsen or persist after a concussion should be evaluated in the emergency department. An athlete should not be allowed to resume sports participation until all symptoms of a concussion have resolved.
ABSTRACT: Athletes and other physically active patients should be screened for hypertension and given appropriate therapy if needed. Mild hypertension should be treated with non-pharmacologic measures for six months. If blood pressure control is adequate, lifestyle modifications are continued. If control is inadequate, low-dose therapy with an angiotensin-converting enzyme inhibitor or a calcium channel blocker may be started. A thiazide diuretic may be used as first-line treatment for hypertension in casually active patients; however, diuretic therapy is less desirable in high-intensity or endurance athletes because of the risk of hypovolemia or hypokalemia. If beta blockade is needed, a combined alpha-beta blocker may be the best choice. When the target blood pressure is achieved, long-term follow-up care and management should be emphasized. If excellent control is maintained for six to 12 months, medication may be reduced or withdrawn in a small number of patients. If the target blood pressure is not achieved, the medication dosage may be adjusted, or a second medication, usually a diuretic, may be added. Physicians need to be aware of the effects of various medications on exercise tolerance and the rules for participation established by sports regulatory bodies (Am Fam Physician 2002;66:457-8).
ABSTRACT: Youth sports participation carries an inherent risk of injury, including overuse injuries. Little leaguer's shoulder, a stress fracture of the proximal humerus that presents as lateral shoulder pain, usually is self-limited. Little leaguer's elbow is a medial stress injury; treatment consists of complete rest from throwing for four to six weeks followed by rehabilitation and a gradual throwing program. Spondylolysis is a stress fracture of the pars interarticularis. Diagnostic modalities include plain film radiography, bone scan, computed tomography, single photon emission computed tomography, and magnetic resonance imaging. Treatment usually is conservative. Spondylolisthesis is the forward or anterior displacement of one vertebral body over another and may be related to a history of spondylolysis. Diagnosis is made with plain film radiography and graded according to the amount of displacement. Osgood-Schlatter disease presents as anterior knee pain localized to the tibial tubercle. Diagnosis is made clinically, and most patients respond to conservative measures. Calcaneal apophysitis (or Sever's disease) is a common cause of heel pain in young athletes, presenting as pain in the posterior aspect of the calcaneus.
Common Problems in Endurance Athletes - Article
ABSTRACT: Endurance athletes alternate periods of intensive physical training with periods of rest and recovery to improve performance. An imbalance caused by overly intensive training and inadequate recovery leads to a breakdown in tissue reparative mechanisms and eventually to overuse injuries. Tendon overuse injury is degenerative rather than inflammatory. Tendinopathy is often slow to resolve and responds inconsistently to anti-inflammatory agents. Common overuse injuries in runners and other endurance athletes include patellofemoral pain syndrome, iliotibial band friction syndrome, medial tibial stress syndrome, Achilles tendinopathy, plantar fasciitis, and lower extremity stress fractures. These injuries are treated with relative rest, usually accompanied by a rehabilitative exercise program. Cyclists may benefit from evaluation on their bicycles and subsequent adjustment of seat height, cycling position, or pedal system. Endurance athletes also are susceptible to exercise-associated medical conditions, including exercise-induced asthma, exercise-associated collapse, and overtraining syndrome. These conditions are treatable or preventable with appropriate medical intervention. Dilutional hyponatremia is increasingly encountered in athletes participating in marathons and triathlons. This condition is related to overhydration with hypotonic fluids and may be preventable with guidance on appropriate fluid intake during competition.
Sports Physicals: A Coding Conundrum - Feature
ABSTRACT: Thousands of young athletes receive preparticipation evaluations each year in the United States. One objective of these evaluations is to detect underlying cardiovascular abnormalities that may predispose an athlete to sudden death. The leading cardiovascular causes of sudden death in young athletes include hypertrophic cardiomyopathy, congenital coronary artery anomalies, repolarization abnormalities, and Marfan syndrome. Because these abnormalities are rare and difficult to detect clinically, it is recommended that family physicians use standardized history questions and examination techniques. Athletes, accompanied by their parents, if possible, should be asked about family history of cardiac disease and sudden death; personal cardiac history; and exercise-related symptoms, specifically syncope, chest pain, and palpitations. The physical examination should include blood pressure measurement, palpation of radial and femoral pulses, dynamic cardiac auscultation, and evaluation for Marfan syndrome. Athletes with "red flag" signs or symptoms may need activity restriction, special testing, and referral if the diagnosis is unclear.
Concussion in Sports - Editorials
ABSTRACT: Nontraumatic sudden death in young athletes is always disturbing, as apparently invincible athletes, become, without warning, victims of silent heart disease. Despite public perception to the contrary, sudden death in young athletes is exceedingly rare. It most commonly occurs in male athletes, who have estimated death rates nearly fivefold greater than the rates of female athletes. Congenital cardiovascular disease is the leading cause of non-traumatic sudden athletic death, with hypertrophic cardiomyopathy being the most common cause. Screening athletes for disorders capable of provoking sudden death is a challenge because of the low prevalence of disease, and the cost and limitations of available screening tests. Current recommendations for cardiovascular screening call for a careful history and physical examination performed by a knowledgeable health care provider. Specialized testing is recommended only in cases that warrant further evaluation.
ABSTRACT: The most common head injury in sports is concussion. Athletes who sustain a prolonged loss of consciousness should be transported immediately to a hospital for further evaluation. Assessment of less severe injuries should include a thorough neurologic examination. The duration of symptoms and the presence or absence of post-traumatic amnesia and loss of consciousness should be noted. To avoid premature return to play, a good understanding of the possible hazards is important. Potential hazards of premature return to play include the possibility of death from second-impact syndrome, permanent neurologic impairment from cumulative trauma, and the postconcussion syndrome.
