- incidence has dropped dramatically since widespread vaccination
- hx should focus on immunization status, travel, contact with infected persons?
- presentation: high fever, dry cough, rhinitis, conjunctivitis with clear discharge, distinctive rash
- KOPLIK spots are pathognomonic (occur 1-2 days prior to onset of rash)
- rash is dark red raised (morbilliform) and begins at hairline and spreads to trunk, arms, legs, and eventually hands and feet
41
Rubella (german measles)?
Why do we vaccinate?
Sxs?
Dx?
- uncommon is US, most impt reason we vaccinate is to prevent spread to pregnant women to avoid congenital rubella syndrome
- result from direct infection of dermis
- most common complications: arthralgia and arthritis
- rash is fainter than measles, begins on face and progresses caudally, doesn't coalesce
- rash may be preceded by low grade fever, malaise, URI sxs, may have lymphadenopathy involvling posterior auricular, suboccipital and posterior cervical nodes
- dx difficult as this appear as nonspecific viral illness (ask about immunization hx)
- serum IgM reliable way to confirm dx
42
Cause and spread of Roseola? Sxs?
- results from HHV-6, very common infection
- seroprevalance in most countries is 100% in kids over 2
- complications are uncommon (seizures - during febrile period)
- virus is acquired from close contact with saliva from parents or siblings
- abrupt onset of high fever lasts 3-7 days (occasionally respiratory or GI sxs)
- resolution of fever is followed by ERYTHEMATOUS MACULOPAPULAR RASH that spontaneously resolves (may not appear for 1-2 days after fever breaks)
- mimics meningitis
43
What is fifth disease?

- lesions are in diff stages
- other sxs: malaise, fever
- hx of contact with another infected (either varicella or herpes zoster) within past 10-21 days
- lesions - dew drop on a rose petal
45
How long is chickenpox contagious for? Tx?
- contagious from 1-2 days prior to onset until lesions have crusted
- management: supportive, acyclovir in immunocompromised
- immune globulin may be given to pts exposed to varicella who are at risk for severe disease
- once you have had disease - lifelong immunity
46
What is pityriasis rosea? Signs?
- etiology unclear, harmless
- 1st sign: herald patch - resembles psoriasis or tinea corporis
- following herald patch multiple new lesions that are smaller appear, usually on central trunk
- lesions are often oval with long axis paralleling the lines of skin stress (inverted christmas tree)
- lesions resolve in 6-10 wks and may be pruritic (complaint: "I have this rash that won't go away")
47
What is bronchiolitis? Who are at a greater risk?
- inflammatory process of smaller lower airways, usually caused by RSV
- can progress to respiratory failure and potentially is fatal
- infants with congenital heart disease, chronic lung disease (premature babies), or immunodeficiencies are at risk for severe disease and poorer outcomes
- presentation: fever, URI sxs, and accompanied by tachypnea and wheezing
- management: supportive care - O2
-
48
Other causes of bronchiolitis?
- adenovirus, parainfluenza virus
49
What can be used as prophylaxis against RSV?

50
Presentation of bronchitis? Labs?
- URI sxs with cough and malaise
- coarse bronchial sounds
- WBC normal, CXR clear
- most time it is viral
- abx usually not helpful
51
Pneumonia? usually viral or bacterial? Difference in presentation? labs?
- most cases in kids are viral
- but unable to predict which cases are viral so we tx with abx
- causes of bacterial pneumonia vary with age
- viral pneumonia often with prodrome of rhinorrhea, cough, low grade fever, pharyngitis
- bacterial pneumonia: more abrupt, high fever, cough, chest pain and shaking chills
- tachypnea may be only sign of underlying pneumonia
- Elevated WBC, CXR: much more variable than with adults, don't often see a classic lobar consolidation
52
Tx of pneumonia?
- abxs
- maybe bronchodilators if trouble with airway, steroids if asthma
- fluids, O2
- prognosis in immunocompetent is excellent
- hospitalize if severe
53
Cause of Pertussis? Why is it dangerous? Duration?
- Bordetella Pertussis
- highly communicable
- not all individuals will seroconvert with vaccination, many lose immunity over time
- danger: small infant - cough so hard that they go into respiratory distress
- duration: 4-12 wks
54
Onset of pertussis (whooping cough)?
- insidious: starts as URI sxs and slight fever may be present, cough is initially irritating by not paroxysmal
- after about 2 weeks, cough becomes paroxysmal with classic whoop (lasts 2-4 weeks)
- cough so hard that it leads to vomiting
55
Guidelines for pertussis dx?
- ask about IMMUNIZATION status!!!
- classic presentation suspect pertussis
- cough for more than 2 weeks suspect pertussis
- nasal swab for culture (Bordet-Gengou culture medium)
- nasal swab for PCR more sensitive: state lab, results in 3-7 days
56
Tx for pertussis?
- erythro for 14 days
- azithro for 5-7
- tx awaiting lab results if hx of known exposure
- won't shorten course of cough unless given in early phase but it will prevent transmission (educate pt that cough may last a couple months)
57
What is bronchiectasis? Who does it occur in?
- characterized by abnormal dilation and distortion of bronchial tree, resulting in chronic obstructive lung disease
- condition is the end result of a variety of pp processes, usually including some combo of infection and impaired airway drainage or obstruction
- CF is most common cause of bronchiectasis in kids
58
PP of bronchiectasis?
- induction of bronchiectasis reqrs 2 factors:
infectious insult, and impaired mucus clearance, airway obstruction or defect in host defense
- only common in CF pts
59
When should you consider a malignancy or rheumatologic/autoimmune diseaes in pts?
- with a persisten fever and when mult organ systems are involved (less likely that it is an infection)
60
When should you consider kawasaki disease?

- congenital rubella syndrome
63
key to roseola dx?
- fever for a couple of days, breaks and then you have a rash
64
How does varicella rash appear?
- starts centrally and on neck, and potentially face, spreads outward, occur in crops and are unilocular
65
When does bronchiolitis peak? Presentation?
