You see a mother in clinic with her 6 month-old infant. The mother is anti-HCV positive, and has a history of IV drug use. The infant’s anti-HCV is negative. What do you do for the infant?
a) HCV PCR
b) Reassure
c) Livery Biopsy
d) Repeat anti-HCV in 6 months
b) Reassure
The infant does not have any antibodies present, therefore vertical transmission did not occur or the child cleared Hepatitis C. No further testing is required.
A girl presents for scalp itching and is found to have nits and lice. What do you recommend regarding return to school?
a) After completing treatment
b) Immediately
c) After she is found to have no evidence of infection
a) After completing treatment
There is no sound medical rationale for excluding a child with nits or live lice from school or child care. A full course of treatment and avoiding close head-to-head activities are recommended. The American Academy of Pediatrics and the Public Health Medicine Environmental Group in the United Kingdom also discourage ‘no nit’ school policies.
The families of children in the same classroom or child care group where a case of active head lice has been detected should be alerted. Information on diagnosis and management of head lice from a credible source should be shared, along with clear messages that head lice are neither a disease risk nor a sign of lack of cleanliness.
10 month old recently immigrated from refugee camp in Turkey. He received 3 oral vaccines and 3 injectable vaccines in his lifetime (question did not specify which vaccines). What do you give him at his first visit to you?
a) Pneumococcal + Hib
b) DTAP/IPV/Hib + Pneumococcal
c) DTAP/IPV/Hib + Pneumococcal + Hep B
d) No other vaccination at this time
DTAP/IPV/Hib + Pneumococcal
When a child’s vaccine record is unreliable or unavailable, vaccines should be provided as if the child were non-immunized, as a general rule.1 If a child receives an immunization that was received previously (“re-immunization”), it is usually safe, though there is increased risk of a local reaction with some vaccines. While serological tests may be available for diphtheria, tetanus, hepatitis A, measles, mumps, rubella, varicella and hepatitis B, they are not sufficiently comprehensive (e.g., polio is not available), cost-effective or time-sensitive to be practical in most cases.1

CPS: The benefits of influenza vaccine during pregnancy for the fetus and infant <6 months of age
Influenza vaccines are not licensed or recommended for infants <6 months of age[4] because their immune response, when studied, has been variable and vaccine effectiveness is unclear.[6] Two other immunization strategies to protect the very young have been evaluated: ‘cocooning’ (the immunization of postpartum women and an infant’s household contacts); and immunizing pregnant women.
Cocooning programs have met with some success and evidence suggests that the maternal immunization component provides most of an infant’s protection from influenza.[

Measles is a serious infection characterized by high fever, an enanthem, cough, coryza, conjunctivitis, and a prominent exanthem. After an incubation period of 8-12 days, the prodromal phase begins with a mild fever followed by the onset of conjunctivitis with photophobia, coryza, a prominent cough, and increasing fever.Koplik spots represent the enanthem and are the pathognomonic sign of measles, appearing 1-4 days prior to the onset of the rash

Members of the genus Listeria are facultatively anaerobic, non–spore-forming, motile, Gram-positive bacilli that are catalase positive. Two clinical presentations are recognized for neonatal listeriosis: early-onset neonatal disease (<5 days, usually within 1-2 days of birth), which is a predominantly septicemic form, and late-onset neonatal disease (>5 days, mean 14 days of life), which is a predominantly meningitic form
other presentations of GAS
CPS - Invasive GAS:
Confirmed case: Laboratory isolation of GAS from a normally sterile site +/- evidence of invasive disease
Invasive GAS:
Streptococcal TSS
Soft tissue necrosis (NF, myositis, or gangrene)
Meningitis
GAS pneumonia (Pneumonia with isolation of GAS from a sterile site or from bronchoalveolar lavage [BAL] fluid should be regarded as a form of invasive disease for the purposes of public health management, if only isolated from BAL, not considered a a sterile site specimen, thus would not meet national case definition)
Other life-threatening condition(s)
Confirmed case resulting in death

a. fever
b. encephalitis
c. Asymptomatic
d. Mild non-specific illness
asx

Congenital CMV
It may not be possible to confirm the diagnosis of congenital CMV infection if testing is performed after the first three weeks of life (because of the possibility of postnatal acquisition). Newborn dried blood spot testing can be helpful if available, but negative results do not exclude congenital CMV infection. A diagnosis of “possible” congenital CMV infection may be made if all of the following criteria are met:
•One or more signs or symptoms of congenital CMV.
•Other conditions that cause these abnormalities have been excluded. (See ‘Differential diagnosis’ below.)
•CMV is detected in urine or saliva samples (via viral culture, shell vial assay, or PCR) or CMV IgG antibody is detected in the blood after the first three weeks of life, up to one year of age.
