Q

Relationship between exercise and immune function is described as

A

J shaped curve

24
Q

Excessive exercise may impair

A

Immune function and depressive effect lasts up to 24 hrs after exercise

25
Q

Risk factors with infectious diseases

A
  • strenuous exercise resulting in leukocyte depression

  • lack of sleep
  • mental stress
  • poor nutrition
26
Q

What is the most common infection in athletes and the incidence and the pathogens

A

Upper respiratory tract infection

Incidence- average adult 1-6 inflections per year athletes and non athletes

  • symptoms above the neck; nasal congestion, runny nose, sore throat-> they can play but proceed cautiously
  • symptoms below the neck; vomitting, diarrhea, fever, myalgia, stop activity and rest
  • more severe bacterial infection; athlete should after illness and be on antibiotics for any least 24 hours before RTS
29
Q

Infectious mononucleosis (mono)

A
  • common 95% of adults exposed to
  • viral illness of lymphoreticular system (Epstein- Barr virus)

30
Q

Mono diagnosis

A

32
Q

Complications with mono

A
  • spleen enlargement occur in over 50% of cases
  • splenic rupture occur in 0.1- 0.2% of those with mono
  • great concern in those that are athletes participating in sport
33
Q

The return to sport with mono

A
  • recovery 4-6 weeks from diagnosis ( can take over 12 weeks)
  • when a febrile, fatigue resolved and 3 weeks from onset on symptoms you can return to light no contact activity
  • when there is no worsening of symptoms you can make progress to more strenuous activity
  • RTS should be individualized it’s different for everyone
34
Q

Influenza

A
  • not common cold
  • A or B virus
  • highly contagious
  • winter season
35
Q

Influenza symptoms and complications

A
  • day 1-3 sudden appearance of fever, headache, muscle pain, weakness, dry cough, sore throat
  • day 4 fever ,uncle ache decreases, dry throat, cough and chest discomfort more apparent
  • day 8 symptoms decreases

Complications; dehydration, pneumonia, bronchitis, death

36
Q

Influenza treatment

A
  • supportive care, maintain hydration
  • Tylenol/ nsaids
  • antivirals (tamiflu), within 48 hours of symptoms onset
  • isolate athlete for 5 days
  • RTS when symptoms resolved
37
Q

Prevention of respiratory infections among athletes

A
  • wash hands, social distance etc
38
Q

UTI

A
  • urinary bacteria (ecoli)
  • frequent urge to urinate and burning sensation
  • risk factors; female, dehydration, intense exercise, friction and poor hygiene
    -prevention; stay hydrated, cranberry juice, hygiene, loose clothes
  • treatment; antibiotics, pain relief and increased fluid intake
39
Q

Otitis external

A

-usually bacterial
- itching, redness, pain and hearing loss
- risk factors; chronic moisture, trauma from foreign bodies
- prevention; keep ears dry and don’t damage the skin (scratch inside ear is the main rzn things start)
- treatment; antibiotic/steroid combination drops and pain control

47
Q

HSV treatment and RTS

A
  • pain relief, keep dry
  • oral antivirals-> 10 days for initial infection

RTS
