SAEM Clinical Images Series: A Rare Pediatric Scalp Rash

rash

The patient is a 3-month-old, full-term male who presents with a rash on his head. The rash started one day prior to presentation on his forehead and spread to the rest of his head. Today, it developed a central clearing with surrounding redness. He has a history of sensitive skin since birth with patches of eczema and cradle cap. He treats these with Aquaphor and Honest Co. Cream; he has never been prescribed topical steroids for his rashes. Denies fever, cough, rhinorrhea, congestion, decreased appetite, diarrhea, and decreased urination. He had an uncomplicated birth history.

General: Well appearing, no distress.

Skin: Large, serpiginous rash on the left forehead and scalp with central clearing and peripheral erythema as well as areas of erythematous plaques. He has some erythema of the left medial epicanthus. He also has a large erythematous patch at the base of his skull. The remainder of his skin is clear.

CV: Normal rate and rhythm, no murmur.

White blood cell (WBC) count: 8.4

Hemoglobin: 12.4

Hematocrit: 37.1

Platelet Count: 468

Complete metabolic panel (CMP): ALT 30, AST 60, Alk phos 266, Tbili 0.7, Total Protein 6.4

The image is of the cutaneous manifestation of neonatal lupus erythematosus. Neonatal lupus erythematosus is an autoimmune disease caused by transplacental passage of maternal autoantibodies to Sjögren’s syndrome A or B autoantigens (SS-A/SS-B). It can present with reversible changes including cutaneous lesions (most common, in up to 40% of patients), hepatobiliary disease, and cytopenias, which resolve once maternal autoantibodies have been cleared.

All infants that present with concern for neonatal lupus erythematosus should have screening labs performed to evaluate for hematologic, cardiac, and hepatobiliary involvement including a CBC with differential, liver enzymes, and antibody testing. In addition, an EKG is essential given that neonates can present with irreversible total atrioventricular heart block, which can present in utero or after birth.

The rash typically presents in the first few weeks of life but can present as late as 2-3 months of life (usually within 1-2 days of first sun exposure). Eighty percent of cases are not clear at birth and present in the first month of life. The rash appears as a coalescing rash with raised margins, with annular and discoid erythema involving the head in 95% of cases. It is often misdiagnosed as skin infections or eczema if the mom is asymptomatic. Fifty percent resolve by four months of life and 100% by one year.

Any neonate with a slow fetal heart rate or the postnatal diagnosis of atrioventricular heart block warrants immediate maternal testing for these autoantibodies. Most cardiac changes from neonatal lupus are diagnosed before 26 weeks gestation, with <20% later in pregnancy and 2% detected postnatally.

Take-Home Points

  • While cutaneous findings of neonatal lupus most commonly present in the first month of life, they can present as late as 2-3 months.
  • The cutaneous findings associated with neonatal lupus most of the time resolve in 4-6 months (when maternal antibodies are cleared from the infant’s circulation).
  • Any baby with findings concerning for neonatal lupus should have an EKG performed. Around 2% of infants present with heart block postnatally within the first month.

The Febrile Infant: Incorporating the 2021 American Academy of Pediatrics guidelines

Can you trust a febrile infant?

“No” has been, and continues to be, the resounding answer over the last 40 years as researchers and clinicians work to determine the optimal evaluation and management of the well-appearing young febrile infant [1].

The goal remains to identify infants with bacterial infections in this at-risk cohort of patients while also considering the balance of cost-effectiveness on a population scale and the potential for iatrogenic harm with evaluation such as unnecessary lumbar punctures, unnecessary antibiotics, and unnecessary hospitalization. Fortunately, bacteremia and bacterial meningitis in this age group are uncommon [2]. Unfortunately, delayed or missed diagnosis can be devastating [1-3].

In the most recent 2021 Clinical Practice Guideline, the American Academy of Pediatrics (AAP) aims to provide guidance with 3 separate age-based algorithms for the evaluation and management of the well-appearing febrile infant [4]. These guidelines were made possible by the recent PECARN, Step by Step, and other studies and the invaluable information they have provided [5-7].

Who’s included?

  • Well-appearing febrile infants
    • The AAP acknowledges that clinician experience is likely the best determinate of what is “well-appearing”, further admitting that there is no measure or definition of either “experience” or “well-appearing”
  •  Febrile
    • Rectal temperatures of  38.0C or 100.4F at home in the past 24 hours or determined in a clinical setting
    • Subjective fevers at home are excluded
  •  Gestation
    • Between 37-42 weeks
    • Premature infants excluded
  • Age
    • Days 8 to 60 and have been discharged home following birth

Who is not included?

  • Preterm or infants with congenital/chromosomal abnormalities
  • Infants with focal bacterial infections
  • Cellulitis, omphalitis, septic arthritis, osteomyelitis
  •  Bronchiolitis
    • With or without a positive RSV test
  •  Immunocompromised
    • Either suspected or known deficiency
  • Immunizations in the previous 48 hours

It should also be noted that the AAP has named the following as high-risk inflammatory markers that will be referenced in the soon-to-be-discussed guidelines [4,5].

  • Temperature >101.3F (38.5C)
  • C-reactive protein (CRP) > 20 mg/L
  • Procalcitonin >0.5 ng/mL
  • Absolute neutrophil count (ANC) >4000 mm3  (or 5200 mm3 if your facility does not have procalcitonin available)

The Groups

While the AAP makes the distinction of an age 0-7 days group from the age 8-21 days, they provide no specific recommendations about emergency department (ED) management in the youngest group [4]. Despite this, these infant groups are likely best evaluated and managed similarly in the ED:

  • Urinalysis (UA) +/- urine culture if indicated by UA
  • Blood culture
  • Lumbar puncture (LP)
    • Cell count, Gram stain, glucose, protein, bacterial culture, and enterovirus PCR (if available)
  • Admission

Inflammatory markers are not required to determine ED management in this age group but may guide inpatient clinicians.

Treatment

  • Ampicillin IV or IM
  • Ceftazidime IV or IM or gentamicin IV or IM

The addition of acyclovir to IV antibiotics depends on the following risk factors which increase the likelihood of HSV:

  • Maternal genital HSV lesions or fever 48 hours before or after delivery
  • Infants with vesicles, seizures, hypothermia, mucous membrane ulcers
  • CSF pleocytosis with a negative Gram stain result
  • Leukopenia, thrombocytopenia, or elevated AST/ALT levels

Although many febrile infants in this group will still require a full evaluation for sepsis, there are some new alternatives in patients meeting certain criteria. At the minimum, all 22-28 day old infants will need:

  • UA +/- culture
  • Blood culture
  • Inflammatory markers (ANC, CRP, procalcitonin)

Further management of a well-appearing infant in this group can be based on the following pathways:

    1. If UA positive with negative inflammatory markers
      • LP may be performed but is not required
      • IV antibiotics and admission are required regardless
    2. If UA negative with negative inflammatory markers, then there are 2 options
      • Perform LP
        • If LP negative, then the patient can be given a dose of parenteral antibiotics and discharged home with close follow-up in 24 hours.
        • If LP is traumatic or pleocytosis is present, administer antibiotics and admit.
      • Defer LP
        • Antibiotics may be administered, but the patient should be admitted.
    3. If UA negative and ANY positive inflammatory marker (procalcitonin > 0.5 mg/mL, CRP >20 mg/L, ANC >4000, or temperature >101.3F), LP is required
      1. If LP positive
        • Admit with IV antibiotics
      2. If LP negative
        • Admit +/- antibiotics, OR
        • Discharge home after one dose of parenteral antibiotic with 24-hour follow-up

Treatment

  • Same antibiotic options as the day 0-21 infants

The nuances of this group’s decision tree revolve around the inflammatory markers.

Each infant in this group should have the following completed:

  • Urinalysis
  • Blood Cultures
  • Inflammatory markers (CRP, ANC, and procalcitonin)

If everything is negative (UA & inflammatory markers):

  • Infants may be discharged home without antibiotics and with close follow-up within 36 hours.

If inflammatory markers are negative:

  • Infants with a positive urinalysis and negative inflammatory markers may be treated with oral antibiotics.
    • They may be either admitted to the hospital for observation or discharged with 24-hour follow-up.
    • No LP needed.

If inflammatory markers are positive:

  • A LP may be performed if the clinician feels it necessary but is not required.
    • If performed and CSF is negative the infant may be discharged with close follow-up.
    • Given high risk of bacteremia with elevated inflammatory markers in this age group, a dose of parenteral antibiotics prior to discharge is appropriate.
  • If LP deferred:
    • Administer parenteral antibiotics, and likely admit to hospital.
    • The caveat to this is if they have viral testing completed that is positive and are well appearing.
      • Example: A 48-day-old infant presents with a fever of 100.6F, CRP of 22 mg/L, and otherwise normal procalcitonin, ANC, and UA. The mother reports that an older brother has had a runny nose. Viral PCR testing is positive for rhinovirus. Seeing as the UA is negative, the infant appears well with a positive viral test, they may go home with shared decision-making and close outpatient follow-up, despite a positive inflammatory marker (CRP 22 mg/L) [3].

Treatment

Urinary Tract Infection:

  • Ceftriaxone (IV/IM) or cephalexin/cefixime as oral options.

Concern for Bacteremia/Meningitis:

  • Ceftriaxone + vancomycin
  • May add acyclovir for the above-mentioned antiviral treatment indications.

What should be done if the viral panel is positive?

  • Children 29 days or older with fever from a documented viral source can be managed according to their clinical presentation and can go outside the algorithm.
  • This requires a documented positive viral swab and not just a presentation consistent with a viral syndrome.
  • UTI is common in this age group, and a UA should be obtained [8].

Conclusion

Over the course of nearly the last half century there has been a lack of clear evidence-based guidelines in evaluating the young febrile infant [1]. Although serious bacterial infections in these young, febrile infants are uncommon, studies show that in the first month of life, bacteremia can be present in nearly 3% of febrile infants, with bacterial meningitis occurring in about 1% [2]. The absence of consensus regarding management has led to significant costs due to hospitalizations and their associated iatrogenic complications [9]. In the movement to create new recommendations, shifting epidemiology pushed changes in previous guidelines with a new focus on the use of the now widely available inflammatory markers [10].  With the advent of multiple large-scale studies and the recent improvements in lab testing, the newly updated AAP guidelines provide recommendations on how to manage this challenging population [4-7].

Take Home Points

  • These management strategies can only be used in WELL-APPEARING infants – if they’re ill-appearing, do a complete workup.
  • Evaluation of febrile infants 0-21 days remains the same – do everything (blood culture, UA +/- culture, LP with CSF studies), give antibiotics, and admit.
  • For those infants 22-28 days, get the UA, blood culture, and inflammatory markers to guide management.
    • Not all febrile infants in the 22-28 day subset need an LP, though it should still be obtained in certain clinical circumstances, and discussed between  provider and parents in other situations
  • In infants ≤28 days, a complete workup is still needed even if a viral source is present.
  • Febrile infants 29-60 days old may be sent home after a negative workup with close follow-up.

SAEM Clinical Images Series: An 8-year-old Male with Dysuria

dysuria

An 8-year-old Caucasian male with no significant past medical history presented to the pediatric emergency department (ED) with complaints of three days of abdominal pain and dysuria, accompanied by nausea, vomiting, and poor oral intake. The patient had previously presented to his pediatrician, where he was found to have microscopic hematuria and subsequently sent to the ED. Microscopic hematuria and increased abdominal pain in the ED prompted a point of care ultrasound (POCUS).

GI: Soft on palpation, normal bowel sounds, tender to palpation at midline below the umbilicus.

GU: No trauma or erythema of the penis.

Remaining exam wnl.

Urinalysis (UA): Yellow; Cloudy; Ketones: 15; Protein >=300; Leukocyte esterase: large; Nitrite: positive; WBC/HPF: Packed; RBC/HPF:51-100

Urine Culture: >100,000 staphylococcus CFU/mL

The most likely site of abnormality in this patient is the urethra. Image 1 shows massive bilateral hydronephrosis while image 2 shows hydroureter and bladder wall thickening. This presentation in a male, together with the lab findings suggestive of a UTI, should raise concerns for posterior urethral valves (PUV). PUV, a congenital obstruction of the urethra, is one of the most common causes of lower urinary tract obstruction in males. [1]

The next step in management for patients with probable PUV is a referral to a urologist for a voiding cystourethrogram (VCUG) and cystoscopy to assess for vesicoureteral reflux and valvular obstruction. Patients who are found to have PUV can then undergo incision and correction of the urethral valve. PUV typically presents in the newborn period in males with a poor urinary stream, urinary tract infections, and other voiding complaints and can be corrected with bladder catheterization or valvular ablation [1,2].

Take-Home Points

  • While rare, PUV should be considered in the differential for any pediatric patient presenting with urinary tract-related complaints, abdominal pain, and unexplained nausea or vomiting, particularly in school-aged males.
  • A school-aged male without an underlying diagnosis presenting to the hospital with a UTI should prompt clinicians to look for underlying predisposing conditions, such as PUV – an undertaking in which bedside ultrasound can be extremely useful.
  • Point of care ultrasound (POCUS) is a tool used in real time by emergency physicians to provide evidence for hydronephrosis, which can lead to the diagnosis of PUV.

SAEM Clinical Images Series: A Rare Cause of Post-traumatic Neck Pain

neck pain

A 15-year-old male presents to the pediatric Emergency Department (ED) for evaluation of neck pain for three weeks. The patient is vague as to the development of his symptoms, but his mother reveals patient was assaulted by peers three weeks ago and has had progressively worsening neck pain and stiffness. The patient states symptoms have gotten to the point where he is unable to turn his head but denies fevers, chills, nausea, vomiting, focal weakness, or sensory changes.

Vitals: Temp: 99.4°F; HR 80; RR 18; SpO2 98% on room air

Constitutional: No distress, sitting rigidly in bed.

Neck: Cervical midline tenderness noted with rigid neck and severe tenderness with manipulation, no swelling, erythema, or masses noted.

HEENT: No pharyngeal injection, no visible masses in the oropharynx, no trismus.

CV: Regular rate and rhythm, no murmurs, rubs, or gallops. Good peripheral perfusion.

Abdomen: Soft, non-distended and non-tender.

Neuro: 5/5 motor function to the bilateral upper and lower extremities, normal sensory examination, cranial nerves intact. Negative Kernig’s sign.

White blood cell (WBC) count: 9.5

Platelets: 639

Glucose: 105

CRP: 128

ESR: 100

CSF: Color- Clear; Nucleated Cells- 1; Protein- 25; Glucose- 6

This patient was found to have septic arthritis of the atlantooccipital (AO) joint, noted on the CT shown above, with joint space narrowing and erosion (red arrow) of the right AO joint with associated soft tissue swelling and effusion. Seen on the MRI is further confirmation of the findings suggested on CT of septic arthritis, with additional noting of attenuation of the prevertebral space of C2/C3 suggestive of phlegmon, bilateral AO joint arthritis, and involvement of the atlantoaxial joint, all of which can be seen on the above sagittal cut of the MRI, with the most notable being the pre-vertebral phlegmon (red arrow).

Septic arthritis of the facet joints is a rarity, particularly in pediatrics and in the cervical spine; case reports largely describe a lumbar location in elderly adults with predisposing comorbidities (intravenous drug use, diabetes, immunosuppression) for spontaneous infection. There are no published case reports of traumatic, pediatric AO joint septic arthritis. This patient developed septic arthritis following trauma. As with peripheral septic arthritis, the most common cause is hematogenous spread, and even non-penetrating trauma can predispose a joint to infection as likely occurred in this case. Septic arthritis of the facet joints presents similarly to spondylodiscitis, generally with fever, neck or back pain, and elevated inflammatory markers such as CRP/ESR. If left untreated, it can be a dangerous and refractory cause of sepsis that leads to deadly complications such as concomitant epidural access formation. Oftentimes patients are initially misdiagnosed and re-present multiple times as the preferred image modality for diagnosis is MRI which is not always readily available or ordered. In general, treatment generally includes weeks-long courses of intravenous (IV) antibiotics, though this patient was discharged on oral antibiotics after significant symptomatic improvement on IV therapy after four days.

Take-Home Points

  • Septic arthritis of the cervical facet joints, namely the AO joint, is a rare cause of neck pain in patients with fever and elevated inflammatory markers, and can present after trauma. Generally, it is hematogenously spread and associated with comorbidities such as diabetes, intravenous drug use, and immunosuppression, it should be considered in patients with refractory symptoms or in which there is strong suspicion as it can have dangerous complications.
  • The preferred imaging modality for diagnosis is MRI, though CT can be useful in making the diagnosis radiographically. Treatment generally consists of weeks of IV antibiotics.

SAEM Clinical Images Series: Facial Swelling

facial swelling

A 5-year-old male with a history of recent frontal sinusitis associated with preseptal cellulitis requiring surgery presented with facial swelling. Swelling developed in the 24 hours prior to presentation without facial pain, nausea, or emesis. Denied facial trauma as well as any neurologic deficits, loss of consciousness, headaches, or fever/chills. At the time of his prior surgery, he presented with swelling localized to the left eye along with worsening pain, nausea, and emesis. After surgery, he was discharged in stable condition on antibiotics for 10 days. He has been in his usual state of health since that time.

Vitals: BP 93/59 (Sitting); HR 84; Temp 37.3 °C (99.1 °F) (Oral); Resp 12; Wt 20.6 kg (45 lb 6.6 oz)

General: Active, alert, normal development, and in no acute distress

HEENT: Swelling over the forehead and nasal bridge. Tenderness to palpation over the forehead. No erythema or overlying skin changes.

Nose: Normal appearance. No congestion or rhinorrhea.

Mouth/Throat: Mucous membranes are moist. Oropharynx is clear.

White blood cell (WBC) count: 8.9 x 10^3/uL

Hemoglobin: 11.5 g/dL

Platelets: 365 x 10^3/uL

ANC: 4.490 x 10^3/uL

ESR: 15 mm

CRP: <0.5 mg

In the initial management of this patient, CT imaging of the head with contrast should be used to characterize the lesion and evaluate for intracranial involvement. In our patient, the CT scan showed frontal bone osteomyelitis with possible extension into the subdural space. He was admitted on broad-spectrum antibiotics and surgical washout was performed the following day.

Pott’s Puffy Tumor is a rare but serious complication of sinusitis with potential intracranial involvement. Complications include orbital cellulitis, intracranial abscess, meningitis, and cavernous sinus thrombosis.

Take-Home Points

  • Pott’s Puffy Tumor is a rare potential complication of sinusitis. Early diagnosis and treatment are essential to reduce morbidity.
  • CT of the head with contrast is the initial imaging that should be obtained in the emergency department.

SAEM Clinical Images Series: ‘Tis Not the Season to be Wheezing

wheezing

A 2-year-old male with a history of solitary kidney presented with greater than one month of daily coughing, wheezing, and decreased appetite. The patient was previously seen by his primary care physician after three weeks of symptoms where he was prescribed albuterol as needed for viral bronchospasm. The patient’s wheezing did not improve after two weeks of albuterol treatment so a chest x-ray was ordered. The patient’s mother denied any fevers, vomiting, diarrhea, weight changes, or night sweats.

Vitals: BP 131/60; Pulse 148; Temp 36.7 °C (98.1 °F) (Axillary); Resp 28; Wt 15.7 kg (34 lb 9.8 oz); SpO2 95%

General: Alert; well appearing

HEENT: Pupils equally reactive to light; moist mucous membranes; nares with normal mucosa without discharge

Cardiovascular: Regular rate; regular rhythm; normal S1, S2; no murmur noted; distal pulses 2+

Pulmonary: Good aeration throughout all lung fields; clear breath sounds bilaterally; prolonged expiratory phase; stridor with agitation

Abdomen: Soft; non-tender; non-distended

White blood cell (WBC) count: 56.1/uL (Blasts 58%)

Platelets: 288/uL

Uric acid: 8.3 mg/dL

LDH: 2231 iU/LD

D-Dimer: 3.22 ug/mL

Fibrinogen: 463 mg/dL

Bronchospasm, bronchiolitis, viral infection, pneumonia, foreign body aspiration, space-occupying lesion, vocal cord dysfunction, cardiac dysfunction, and acute chest in patients with sickle cell disease.

The radiograph shown demonstrates a mediastinal mass. This patient was ultimately diagnosed with T-cell acute lymphoblastic leukemia. T-ALL can present with fatigue, fevers, weight loss, easy bleeding/bruising, paleness, or a mediastinal mass. Mediastinal masses found on chest x-ray require further evaluation to determine the diagnosis, location, and treatment. If malignancy is suspected, an oncology referral and bone marrow sample will be necessary.

Take-Home Points

  • In patients with first-time wheezing that does not improve with bronchodilator therapy, consider alternative diagnoses and further evaluation.
  • A mediastinal mass is found at the time of diagnosis in 10% to 15% of children with acute lymphoblastic leukemia.

SAEM Clinical Images Series: An Enlarging Scalp Mass

scalp mass

A 27-day-old female infant born at 34 weeks 4 days with a prenatal history of maternal syphilis treated with penicillin presented with an enlarging scalp mass since birth. Since birth, the patient has had a 1 cm erythematous and flat lesion on her scalp. Since that time, the lesion has continued to grow and develop scales. On the day of presentation, the lesion was noted to be 7-8cm in diameter with multiple surrounding smaller lesions. There is some clear to bloody drainage coming from the main lesion. The patient has otherwise been growing and developing normally. No fevers or other sick symptoms. Feeding well. Mom has no concerns with bowel movements or voiding habits.

General: She is active. She is not in acute distress. She is well-developed.

HEENT: No congestion or rhinorrhea. Mucous membranes are moist. No posterior oropharyngeal erythema.

Cardiovascular: Normal rate and regular rhythm. Normal pulses. No murmur heard.

Pulmonary: Respiratory effort is normal. No retractions. Normal breath sounds. No wheezing.

Skin: Skin is warm. Capillary refill takes less than 2 seconds. On the left side of the scalp, there is a large raised keratinized plaque with a stuck-on appearance. Some red blood is noted when tapped with a white sheet. The plaque is firm and non-tender. On the rest of the scalp, there are several peeling flat lesions with hair attached, and intermittent alopecia.

Neurological: No focal deficit present. She is alert. Suck is normal.

Scalp ultrasound: Posteriorly exophytic left parietal lesion is peripherally echogenic, possibly representing a calcified lesion or cephalohematoma. CT or MRI may be useful for further evaluation, as clinically indicated.

a. Seborrheic Dermatitis: A common, self-limiting eruption consisting of erythematous plaques with greasy, yellow-colored scales that distribute to the areas of the body with sebaceous glands.

b. Atopic Dermatitis: Erythematous, scaly, crusted lesions that are poorly demarcated. It is pruritic and commonly involves the cheeks, scalp, and extensor surfaces.

c. Psoriasis: Uncommon in infants, but can mimic seborrheic dermatitis with sharply demarcated, shiny, erythematous plaques with fine silvery scales in non-intertriginous regions.

d. Tinea Capitis: While rare, tinea can present with a scaly scalp rash in infants. There may be a mild to moderate inflammatory reaction associated as well as hair loss.

e. Langerhans Cell Histiocytosis (LCH): LCH can present as refractory seborrheic dermatitis. There may also be papules or reddish-brown nodules that appear with the rash.

Pityriasis Amiantacea secondary to Seborrheic Dermatitis with a significant build-up of crust and scale. Pityriasis amiantacea is an exaggerated inflammatory response to regional dermatitis, most often seborrheic dermatitis. Treatment consists of a keratinolytic and antibacterial ointment. In this patient, 1:4 part vinegar and water soaks were recommended twice daily, followed by mupirocin ointment until the resolution of the lesions.

Take-Home Points

  • Seborrheic dermatitis is a commonly presenting rash in infancy.
  • When rashes are refractory to conservative management, additional diagnoses and sequelae need to be considered.
