What is Potts puffy tumor?
Pott puffy tumor is a forehead swelling due to frontal bone osteomyelitis with associated subperiosteal abscess. PPT is a rare complication of sinusitis, but can also occur due to trauma. PPT is most commonly seen in the pediatric and young adolescent populations due to the pneumatization process and venous drainage.

Stasis, endothelial injury, hypercoagulability
How do you diagnose pulmonary embolus?
CT angiogram
How do you treat thrombosis in kids with sickle Cell?
Anticoagulation: enoxaparin is the standard. Usually three months for provoked DVT/PE or 6 to 12 months for unprovoked. Then transition to oral rivaroxaban
Hemarthrosis, easy bruising, epistaxis, bleeding with circumcision would make you worry for what?
Hemophilia
Suspect this with an isolated elevated PTT
Management of hemophilia
Desmopressin and aminocaproic acid for preventing clot breakdown
Factor infusion or FFP for low factor levels
Patient presents with mucosal bleeding, bruising, menorrhagia
Von Willebrand disease (platelet adhesion factor)
Genetic causes of thrombocytopenia
Fanconi disease, gaucher, Wiskott-Aldrich, TAR syndrome
Baby presents with absent radius. What diagnostic modality would be our next step?
CBC to look for thrombocytopenia.
Tar syndrome
Treatment for ITP
Usually supportive care but short course of steroids if needed
Treatment for HUS (fever, anemia, thrombocytopenia, renal dysfunction)
Early hydration improves outcomes.
Eculizimab is helpful for some sub types
Fever and neutropenia that waxes and wanes every 3 to 6 weeks
Cyclic neutropenia
Treat w G-CSF
Pancreatic insufficiency, bone marrow dysfunction, skeletal abnormalities and short stature
Schwachman diamond syndrome
And what is the most common cause of child maltreatment?
Neglect
If you suspect abuse or neglect, are you compelled to report the family even if you’re not sure?
Yes, we are mandated reporters
What is the most common presentation of physical abuse?
Skin injuries
Is bruising normal in an infant?
Bruising is rare in preambulatory infants
What is the most common location for accidental bruising?
Over bony prominences
If location is on the butt, genitals, cheeks, etc. that is less likely to be accidental
What do abusive patterns of bruises look like?
More bruises, clusters of bruises, imprint of object
Children and infants presenting with excessive bruising, what workup should we do?
CBC, PT/PTT, VWf ag/activity, factor 8 and 9 levels for hemophilia
What is TEN4-FACESp
Infant/children with bruises in these areas should raise your concern
TEN: torso, ears, neck.
4: children less than four years of age and infants less than four months of age.
FACES: frenulum, angle of the jaw, cheek, eyelid, sclera.
P: patterned injury
What type of fractures are highly associated with the abuse?
Infants and toddlers with midshaft, humorous or femur fractures.
Non-mobile infants with fractures.
High specificity fractures: rib, scapula, classic metaphyseal lesions, vertebrae, sternum
What labs to workup fractures in kids you suspect abuse in?
Ca, Phos, Alk phos, Mg, PTH, 25-hydroxyvitamin D
Indications for skeletal survey
• Bruises, burns or other skin injuries in non-ambulatory infants
• Oral injuries in non-ambulatory infants
• Burns concerning for abuse in children < 2
• Fractures concerning for abuse in children < 2
• Unexplained intracranial injuries (hemorrhage and hypoxic-ischemic injury)
• Unexplained, unexpected sudden death
Infants and siblings < 2 years and household contacts of an abi child **Twins!!)
recommended occult workup for abdominal injury in children less than five years old?
AST/ALT, lipase
If AST/ALT is > 80 or lipase > 100 get a CT of the abdomen with contrast or if there’s any external evidence of abdominal injury
What is the leading cause of child abuse related fatality?
Abusive head trauma
Initial screening for abusive head trauma
Head CT not head ultrasound
If head CT shows intracranial injury or hemorrhage in a suspected child abuse case, what should be your next step?
MRI brain and spine
Dilated opthalmalogic exam
How do you calculate prevalence?
Total number of people with the condition divided by population at risk
How do you calculate sensitivity in the 2 x 2 table?
A/A +C or true positive/everyone with the disease
SNOUT rules out
Is sensitivity dependent on incidence?
No it’s just dependent on characteristics of the test itself
What does specificity indicate in plain terms?
If a patient does not have the disease what is the likelihood the test will be negative
How do you calculate specificity?
True negative/everyone without disease
D/B+D
SPIN rules in
In plain terms, what is positive predictive value and negative predictive value?
PPV: what is the likelihood I have the disease if I test positive?
NPV: what is the likelihood I don’t have the disease if I test negative?
What is a graph that shows the trade-off between sensitivity and specificity called?
Receiver operating characteristic curve
If someone has screened positive for a disease like positive PPD…What is the most important characteristic of a confirmatory test?
That it is highly specific.
If you hear screening think specificity
Screening for a disease like screening for ebola amongst travelers. What is the most important statistic?
Sensitivity
Screening for a disease like screening for ebola amongst travelers. What is the most important statistic?
Sensitivity
What would be the most important statistical test if you are deciding to omit urine culture in a febrile infant with negative urinalysis?
NPV
What statistical test is most important if you’re interpreting a positive rheumatoid factor in a patient with no signs or symptoms of auto immunity
PPV
What is a case control study?
Retrospective; compares cases (with disease) to controls (without) to identify past exposures
What is a case control study?
Retrospective; compares cases (with disease) to controls (without) to identify past exposures
What is a cohort study?
Prospective or retrospective; follows a group over time to assess the effect of exposures on outcomes
What is a cross-sectional study?
Snapshot; examines the relationship between variables and outcomes in a population at one point in time
What is a randomized controlled trial?
Prospective; participants are randomly assigned to groups to test the effect of an intervention
