2 First year team physician’s dilemma This is your 1st yr as team physician for the local high school. All the talk in the community is about the school’s football team, which is expected to win the state championship this season. The coach of the football team “doesn’t like to lose” and was known to put pressure on the previous team physician to give medical clearance to player before games.
3 Q1Which of the following is the most common cause of sudden death in an athlete younger than age 35 years?CADPremature CADMyocarditisHCMRupture of the aorta
4 Q2Which of the following is a contraindication to participation in contact sports?Sickle cell traitHIVSolitary testicleFever of 102FConvulsive disorder, well controlled
5 Q3Which of the following tests is recommended for routine screening of athletes during the preparticipatation evaluation (PPE)?EchoECGExercise stress testVision screenUA
6 Can’t play any contact sports Can’t play until BP is under control During PPE, you note that the 17yo boy has a BP of 148/95mmHg. His past medical history is negative, and he has never been told that he had HTN. He is 6 ft2in tall and wt 175 lb. As the team physician, you tell himCan’t play any contact sportsCan’t play until BP is under controlHe is cleared to play, but must have his BP measured twice during next monthIf he begins BP med immediately, then he is clearedHe must lose 10lb before he will be cleared
7 Q5The school’s wrestling team has had an unusually high amount of injuries this season. Which of the following conditions is reason to disqualify a wrestler from competition?Herpes simplexHep CInguinal herniaDiabetes mellitus
8 Q6 Which of the following statement concerning PPE is true? About 10% of athletes are denied clearance during PPEThe PPE ideally should be performed 6 month prior to present practiceA primary objective of the PPE is to detect conditions that may predispose an athlete to injuryA complete hx will identify about 95% of problems affecting athletes.
9 IntroductionEach yr , between 17 and 25 million adolescents engage in some type of sports activity.>6 million high school athletes at about 20,000 high schools.>2 million injuries occur each yr requiring 500,000 doctor visit and 30,000 hospitalization.Since 8/08, at least 12 high school football, 2 youthleague football and 2 soccer players have died during or as a result of athletic participation.

16 QuizThe most common abnormalities leading to disqualification are _____________The most common cause of sudden death in age older than 35?
17 Major Questions to ask in Medical History Screening?
18 Critical screening questions Exertional CP or discomfort, or SOB?Exertional syncope or near-syncope, or unexpected fatigue?Hx of cardiac murmur or systemic HTN?FH of HCM, long QT syndrome, Marfan syndrome, significant dysrhythmias?FH of premature death or known CAD in a first- or second-order relative younger than 50 years? (More concern if younger than 40 years.)

25 Athletic Heart Syndrome The Merck Manual online library A constellation of structural and functional changes that occur in the heart of athlete. →Asymptomatic; →Signs include bradycardia, a systolic murmur, and extra heart sounds. →ECG abnormalities are common. →Diagnosis is clinical or by echocardiography. →No treatment is necessary. →It must be distinguished from serious cardiac disorders.

27 Athletic Heart Syndrome Prognosis and Treatment Although gross structural changes resemble those in some cardiac disorders, no adverse effects are apparent. In most cases, structural changes and bradycardia regress with detraining, although up to 20% of elite athletes have residual chamber enlargement, raising questions, in the absence of long-term data, about whether the athletic heart syndrome is truly benign.No treatment is required, although 3 mo of deconditioning may be needed to monitor LV regression as a way of distinguishing this syndrome from cardiomyopathy. Such deconditioning can greatly interfere with an athlete's life and may meet with resistance.
