Q

Causes of apnea in infants (based on system)

A

CNS

  • Seizures ==> hemorrhage, meningitis/encephalitis, structural abn, metabolic or electrolyte d/o, genetic d/o, epilepsy
  • Breath-holding spells == in kids 6mo-6yo; halting breath during expiration (reflexive d/t injury or anger) - pallid / cyanotic –> LOC +/- seizure, asystole
  • Increased ICP ==> bleed, trauma, tumor, infection
  • non-accidnetal closed head injury

CARDIAC

  • congenital heart block; long-QT syndrome, arrythmia==> bradycardia + apnea
  • congenital heart disease (esp. ductal-dependent lesions - Tetralogy of Fallot) –> acute decompensation in first few weeks of life assoc. with decreased pulmonary BF

PULMONARY

  • RSV infection == esp. premature infants and kids <2yo
  • pertussis
  • other lower respiratory infections = viral/bacterial pneumonias

GI
- swallowing abnormalities
- transesophageal fistula = chronic
+/- reflux ==> choking, gagging, color changes, laryngospasm

SYSTEMIC

  • systemic sepsis (in infants <1mo) == apnea, pallor, tachycardia, tachypnea, fever/hypothermia, decreased feeding, change in tone (==> Group B Strep,E. coli, Listeria(–>meningitis), HSV (–>encephalitis))
  • botulinum toxin (soil, raw honey) (in infants <1yo) == hypotonia, constipation, paralysis, resrpiatory failure
  • metabolic disorders == esp. apnea and AMS
  • meds/toxins == respiratory depression, cardiac arrhythmias, seizures
  • environmental exposures (carbon monoxide) == AMS, hypoxia, respiratory distress

21
Q

Jeremy has a poor suck, a tense full anterior fontanel, an intermittent irritable cry, and decreased tone in his arms and legs. He will open his eyes only to pain, and when his eyes are open he does not fix on or follow examiner’s face. Responds to pain with movement, but does not move spontaneously.

Assign the glasgow coma scale

A

= 10 (moderately depressed neurological status)

EYE
to pain == 2/4

MOTOR
no spontaneous movement, decreased tone =4/6

VERBAL
intermittent irritable cry = 4/5

22
Q

explain how glasgow coma scale works in terms of determining treatment in an infant

A

<8 ==> severe neurological compromise + coma
8-13 ==> moderate neurological compromise
>13 ==> mild/no neurological compromise

23
Q

An 18-year-old mother with her 3-month-old son arrives at urgent care clinic with a chief complaint of “my baby stopped breathing!” She and her baby are rushed into a triage room, where her son is noted to be very lethargic with increased work of breathing. As vital signs are being obtained, the mother reports “my baby stopped breathing in the car coming here, and didn’t start again until I reached over and jostled his car seat!” Mom then shared that “my boyfriend said he rolled off the couch last night. Could it be related?” Mom also stated that her son hasn’t been as active as usual, and has been vomiting occasionally. Physical exam is notable for a respiratory rate of 70 bpm with intercostal retractions and crackles in the right lower lung fields posteriorly. You admit this patient with the diagnosis of pneumonia for empiric antibiotics and support, pending additional evaluation. CXR subsequently demonstrates a RLL infiltrate and faint, vertical lines on several posterior ribs bilaterally. What is the best next step in management?

 Single Choice Answer:
Please select one answer.  
A		Obtain a PTH level	
B		Sweat chloride testing	
C		Skeletal survey (more x-rays)	
D		Anticipatory guidance about appropriate car seat usage	
E		Head ultrasound
A

C.

lethargic
tachypnea + intercostal retractions, RLL crackles (pneumonia)
“rolled off the couch”

3 months old == can’t roll yet
+ less active, vomiting

= likely child abuse - “faint, vertical lines on several posterior ribs bilaterally”
In this case a skeletal survey is essential. Posterior rib fractures are always concerning findings. While treatment of the patient’s pneumonia has been initiated, a complete skeletal survey will screen for other worrisome findings, including multiple fractures in different stages of healing, fracture of the femur or tibia in a non-walking child, and skull fractures.

Although head trauma (from falling from the couch) could result in an intracranial bleed and lethargy, the best test for such a bleed and/or skull fracture would be a CT scan, not an ultrasound.

24
Q

A 2-month-old male is brought to the ED after his mother found him in his crib not breathing. She says he had no color and was still when she found him, but quickly regained his color. While you are examining him he starts having a tonic-clonic seizure and subsequently is found to have a temperature of 96 F, HR 200 bpm, and RR 18 bpm. On exam he cries intermittently, does not track you with his eyes, has a tense, full fontanelle, and decreased tone throughout. You also notice a healing bruise on his left arm. After assessing circulation, airway, and breathing you obtain IV access. What is the next step in your diagnostic workup?

 Single Choice Answer:
Please select one answer.  
A		Skeletal survey	
B		Lumbar puncture	
C		Head CT	
D		Head MRI	
E		Social work consult
A

C

apneic spell
+ seizure

hypothermic, tachycardic, hypochypnic

Motor 4/6
Verbal 4/5
Eyes 2/4

= 10

tense, full fontanelle

for head trauma
head CT is highly sensitive for an intracranial bleed, such as a subdural hematoma, can be quickly carried out in the emergency setting, and may require urgent intervention.

25
Q

A 10-month-old male is brought to the emergency room by his very concerned and frantic grandmother. Earlier that day, she retrieved the child from his mother’s new boyfriend, who had been watching him while his mother was at work. The grandmother makes it very clear she does not approve of this new boyfriend, and she is concerned that he is rough with her grandson. She demands that her grandson be worked up for injuries and that a restraining order be placed against the boyfriend. Which of the following finding does NOT indicate that a child is being physically abused?

 Single Choice Answer:
Please select one answer.  
A		Retinal hemorrhages on fundoscopy	
B		A concaved, crescent-shaped mass on head CT	
C		A spiral fracture of the tibia	
D		Two posterior rib fractures	
E		A metaphyseal fracture of the wrist
A

C. he could already be walking
“toddler’s fracture,” fracture of the tibia is a commonly occurring fracture in young, ambulatory kids. It is not a sign of abuse. Toddler’s fracture is described as a subtle, non-displaced oblique fracture of the distal tibia in kids aged 9 months to 3 years. The child will usually present with acute onset of limp and refusal to bear weight on one leg. It usually occurs when a toddler falls while twisting, or gets a foot caught and falls while trying to free the foot.

which DO indicate abuse
A
B
D = any rib fractures
E =  Metaphyseal fractures, also called “bucket handle” or corner fractures, are caused by torsional force on the limb, or by violent shaking. While these can occasionally occur in older children who test the limits of their limbs, this would be unlikely in an 10-month-old. You can never be reassured by a metaphyseal fracture, and should always have child abuse on your differential when this type of fracture is apparent.
26
Q

A 5-month-old male presents to urgent care with his mother who states that she witnessed her son stop breathing and turn blue for about 25 seconds. Upon physical stimulation by the mother, the patient began to breathe again. This is the first time she has ever witnessed this happening. The patient’s birth and past medical history are unremarkable. Physical exam is unremarkable, vital signs are stable and normal, and lab studies are all within normal limits. Which of the following is LEAST likely to be on the differential diagnosis as a cause for this patient’s ALTE (apparent life threatening event)?

 Single Choice Answer:
Please select one answer.  
A		Seizures	
B		Arrhythmia	
C		Infection	
D		Gastroesophageal reflux	
E		Congenital heart disease
A

E. it is unlikely for a patient with congenital heart disease to first present with an ALTE. This patient has no past medical history and his birth history was unremarkable. Typically the patient will suffer from acute decompensation within the first few weeks of life. These patients will also have growth problems, difficulty with feeding and a murmur is often appreciated on physical exam. Children with undiagnosed Tetraology of Fallot may have intermittent episodes of cyanosis while blood supply is diverted from the pulmonary vasculature.

what IS on the difffernetial
A
B
C  = RSV/pertussis
D = reflux? (not sure of the causal relationship, but it is related)
27
Q

A young couple presents to the ED with their 2-month-old son complaining of excessive sleepiness and difficulty arousing him after his nap. Per the parents, the PMH and prenatal course are unremarkable, except that the patient has always been very fussy and would often cry despite being held and cradled. He is cared for during the day by his babysitter. Today he had been in his usual state of fussiness when the babysitter arrived, and they returned to find him napping quietly in his cradle but could not arouse him from sleep when it came time for his feeds. He finally opened his eyes after several minutes of gentle nudging but seemed to quickly fall asleep again. On exam, patient is afebrile with poor tone and is only mildly responsive to painful stimuli. Eye exam shows dilated pupils and an ophthalmology consult reveals retinal hemorrhages. What is the most likely diagnosis?

 Single Choice Answer:
Please select one answer.  
A		Bacterial meningitis	
B		Infant botulism	
C		Intoxication	
D		Closed head injury	
E		Metabolic disorder
A

D

pt always cries

Motor = 4/6 (barely)
verbal = none? (0/5)
eyes = 2/4

shaken by the babysitter

Closed head injuries and retinal hemorrhages in infants and children are secondary to violent shaking or throwing, resulting in tearing of the bridging vessels. Retinal hemorrhages, as seen in our patient, are pathognomonic for shaken baby syndrome. Other signs and symptoms include stiffness, constant crying, seizures, difficulty to arouse, decreased appetite and excessive sleeping. Victims often have no other signs of physical abuse (e.g., bruises).

28
Q

Common characteristics of perpetrators of child abuse/neglect

A
  • someone close (mothers, unrelated adult in the home)

- <40yo

29
Q

RF for child abuse

A

CHILD

  • disabled (need more care; harder to care for)
  • chronic diseases
  • younger age (can’t talk/defend)
  • female gender

FAMILY/COMMUNITY

  • poverty
  • substance abuse
  • partner violence
  • religious practices
  • community violence
  • physical isolation
  • lack of parenting / communication skills
30
Q

1 predictive factor for child abuse

A

crying

31
Q

what do we want to interview caretakers separately in concerns for child abuse

A
  • consider everyone’s safety (concerns for inter-partner violence)
  • is the story consistent (between caretakers)
  • does the story change over time (between medical providers)
32
Q

why is the development of the child important to consider in child abuse

A
  • does the story make sense (can the baby crawl)

- advanced physical development ==> risk of sexual abuse

33
Q

why are considering medical history in child abuse

A
  • bleeding disorders
  • bone dyscrasias

that can explain the child’s lesions.

34
Q

why does the timing of the injury matter

A

if you have old, healed wounds

bones take ~2w to form callus in a kid

35
Q

what constitutes medical child neglect?

what does NOT

A

medical neglect == anything that causes undue harm

NOT (usually)
- lack of vaccines

36
Q

situations constituting neglect

A
  • Bathtub drowning in child < 5 years
  • Harm due to other gross lack of supervision
  • Abandonment
  • Lack of needed food, shelter, clothing, education to support growth and development
  • Lack of or inappropriate medical care resulting in harm
  • Extreme or chronic failure-to-thrive
  • Unexplained infant death or recurrent Acute Life-Threatening Event (particularly with nasal or oral bleeding or facial petechiae)
  • Recurrent SIDs in a family
  • Supplying alcohol or drugs
  • Exposure of newborn to substances, resulting in harm
37
Q

what is the physician’s role in reporting child abuse/neglect

A

ANY SUSPICION ==> not trained / qualified to investigate

38
Q

what is the most “common” type of child maltreatment?

A

child neglect

39
Q

what consitutes ACE?

A

adverse child experiences

  • emotional abuse
  • physical abuse
  • sexual abuse
  • emotional neglect
  • physical neglect
  • mother treated violently
  • household substance abuse
  • household mental illness
  • parent separation / divorce
  • incarcerated household meber
40
Q

what are some physical signs of abuse? (ex. 2yo)

A

bruises of torso, neck, nears
blood under scalp ==> dragged by hair b/l

2 black eyes

hard to get bruised on the trunk through a fall b/c by 2yo, would usually be able to throw out the arms to catch self.

NOT likely abuse
- bruises in forehead

41
Q

what are the long-term effects of maltreatment

A

Physical consequences (e.g., damage to the child’s growing brain) ==> psychological implications (e.g., cognitive delays or emotional difficulties) ==> high-risk behaviors

Depression and anxiety, for example, may make a person more likely to smoke, abuse alcohol or illicit drugs, or overeat.
High-risk behaviors, in turn, can lead to long-term health problems such as STDs, cancer, respiratory and cardiac problems, and obesity.

42
Q

what is this?

- bruising across the buttock on both sides and down at least 1 legs

A

==> impact on various planes of the body (unlikely to be a fall)

43
Q

what is this?

- petechiae in a linear, parallel conformation on the cheek

A

==> thin ruler

==> outline of fingers on the cheek –> grabbing the child by the face

44
Q

what is this?
- bruising on the top of the helix on the inside and along the outside
+/- petechial outline
+/- blood in the ear canal

A

grabbed by the ear and pulled

cuffed ==> perforated ear drum

45
Q

how to work up a child who has been abused

A

REPORT

- CBC, lipase
