“Ringworm”
Ringworm often causes itchy, red, scaly, slightly
raised, expanding rings on the skin of the trunk
of the body, face, groin or thigh fold. The ring
grows outward as the infection spreads, and the
center area becomes less actively infected.
Tinea…
Athlete's foot (tinea pedis). This form affects
the moist areas between your toes and
sometimes on your foot itself.
Jock itch (tinea cruris). This form affects your
genitals, inner upper thighs and buttocks.
Ringworm of the scalp (tinea capitis). This
form is most common in children and involves
red, itchy patches on the scalp, leaving bald
patches.

Chalazion
Chalazion
Chalazions may be treated with any one of the following
methods:
1) Antibiotics and/or steroid drops of injections;
2) Warm compresses;
Warm compresses can be applied in a variety of ways,
The simplest way is to hold a clean washcloth, soaked in
hot water, against the closed lid for five to ten minutes,
three to four times a day. Repeatedly soak the washcloth
in hot water to maintain adequate heat.
3) Massage of expression of the glandular secretions;
4) Surgical incision or excision.

Bacterial infection
usually results from local
spread of adjacent URTI
Preseptal usually follows
periorbital trauma or
dermal infection

Erythema Multiforme
Symmetrically distributed, erythematous, expanding macules or
papules evolve into classic iris or target lesions, with bright red
borders and central petechiae, vesicles, or purpura.
Lesions may coalesce and become generalized.
Vesiculobullous lesions develop within preexisting macules,
papules, or wheals.
Rash favors palms and soles, dorsum of the hands, and extensor
surfaces of extremities and face.
Postinflammatory hyperpigmentation or hypopigmentation may
occur.
Eye involvement occurs in 10% of EM cases, mostly bilateral
purulent conjunctivitis with increased lacrimation.
Mucous membrane blistering occurs in about 25% of cases of
EM, is usually mild, and typically involves the oral cavity.

Febrile Seizures
CRITERIA FOR THE DIAGNOSIS OF
SIMPLE FEBRILE SEIZURE
Between 6 months and 5 years of age
Seizure lasting less than 15 minutes
Fever present prior to the onset of the seizure
No other neurologic diagnoses
Non-focal, generalized seizure, involving all limbs
No severe metabolic disturbance
No more than a single seizure per 24-hour period
No evidence of intracranial infection
Febrile SZ work-up
Clinicians evaluating infants or young
children after a simple febrile seizure
should direct their attention toward
identifying the cause of the child's fever.
In general, a simple febrile seizure does
not usually require further evaluation,
specifically EEGs, blood studies, or
neuroimaging.
Febrile Seizures – Parental
Education
The risk of febrile seizure in the general
population is between ?
2% and 5%
There is no evidence that treating
simple febrile seizures with antiepileptics decreases the incidence of
epilepsy later in life or results in
improved cognitive outcomes.
Febrile Seizures – Parental
Education
If a patient is less than 12 months of age at the
time of the first simple febrile seizure, the risk of
second simple febrile seizure is 50%.
If a patient is over 12 months of age at the time
of the first simple febrile seizure, the risk of a
second simple febrile seizure is 30%.
Following a second simple febrile seizure, the
risk of future simple febrile seizures is 50%,
regardless of the age of the initial simple febrile
seizure.
The risk of epilepsy is minimally increased from
1% to 2.4% in patients who have a simple febrile
seizure
Mumps Clinical Features

Impetigo
Impetigo contagiosa
The most common form of impetigo is impetigo
contagiosa, which usually starts as a red sore on
your child's face, most often around the nose
and mouth. The sore ruptures quickly, oozing
either fluid or pus that forms a honey-colored
crust. Eventually the crust disappears, leaving a
red mark that heals without scarring. The sores
may be itchy
Staphylococcus aureus
Topical antibiotics. Your doctor may prescribe an antibiotic that you apply
to your child's skin (topical antibiotic), such as mupirocin ointment
(Bactroban). Topical antibiotics avoid side effects such as diarrhea that can
result from some oral medications, but as with oral antibiotics, bacteria can
become resistant to them over time.
Oral antibiotics. Your doctor is likely to prescribe an oral antibiotic for
ecthyma and severe cases of impetigo contagiosa. The specific antibiotic will
depend on the severity of the infection and any allergies or conditions your
child might have. Be sure to finish the entire course of medication even if
your child seems better. This helps prevent the infection from recurring and
makes antibiotic resistance less likely.
Pityriasis Rosea
It most often develops in the spring and the fall, and seems to
favor adolescents and young adults.
The skin rash follows a very distinctive pattern. In 3/4 of the
cases, a single, isolated oval scaly patch (the "herald patch")
appears on the body, particularly on the trunk, upper arms, neck,
or thighs.
These patches often form a pattern over the back resembling the
outline of an evergreen tree with dropping branches. Patches
may also appear on the neck and, rarely, on the face. These spots
usually are smaller than the "herald" patch. The rash begins to
heal after 2-4 weeks and is usually gone by 6-14.
Aveeno oatmeal baths, anti-itch medicated lotions and steroid
creams may be prescribed to combat the rash. Lukewarm, rather
than hot, baths , ERYC, Famvir

Erythema Infectiosum (Fifth
Disease)
History:
Erythema infectiosum typically has an incubation period of 4-14
days and is spread primarily via aerosolized respiratory droplets.
Transmission also occurs through blood products and from
mother to fetus.
The prodromal phase often is mild enough to be noticed only
rarely but may include headache, coryza, low-grade fever,
pharyngitis, and malaise.
Infrequently, nausea, diarrhea, arthralgias, and abdominal pain
may occur.
In hosts who are immunocompetent, the patient is viremic and
capable of spreading the infection only during the incubation
period.
Classic cutaneous findings follow within 3-7 days for some
patients, while other patients may manifest no findings.
Erythema Infectiosum (Fifth
Disease)
Physical:
Pertinent physical findings predominantly are limited to the skin and joints.
Skin (first stage): The exanthem begins with the classic slapped-cheek appearance.
The bright red erythema appears abruptly over the cheeks and is marked by nasal,
perioral, and periorbital sparing. The exanthem may appear like a sunburn,
occasionally is edematous, and typically fades over 2-4 days.
Skin (second stage): Within 1-4 days of the malar rash, an erythematous macularto-morbilliform eruption occurs primarily on the extremities. While the eruption
tends to favor the extensor surfaces, it can involve the palms and soles. Pruritus is
rare.
Skin (third stage): After several days, most of the second stage eruption fades into
a lacy pattern, with particular emphasis on the proximal extremities. Despite its
synonym, slapped-cheek disease, the reticulate pattern is distinctly characteristic
for erythema infectiosum and may be the only manifestation of the illness. The
third stage lasts from 3 days to 3 weeks. After starting to fade, the exanthem may
recur over several weeks following physical stimuli, such as exercise, sun exposure,
friction, bathing in hot water, or stress.
Erythema Infectiosum (Fifth
Disease)
Complications of PV-B19 infection include the
following:
Aplastic crisis: The parvovirus infects erythroid cells, causing
a reticulocytopenia that lasts 7-10 days. A healthy host
experiences no consequences, since the normal lifespan of a
red blood cell is 120 days. In patients with a background of
shortened red blood cell survival, such as hemolytic anemia,
an acute aplastic crisis ensues.
Congenital infection: PV-B19 can cross the placenta during
pregnancy and have a direct cytotoxic effect on fetal red
blood cells. Infection

Scarlet fever / scarlatiniform rash
Background:
Scarlet fever is a syndrome characterized by exudative
pharyngitis, fever, and scarlatiniform rash. It is caused by
an infection with a pyogenic exotoxin-producing group A
beta-hemolytic streptococci
Infections occur year-round, but the incidence of
pharyngeal disease is highest in school-aged children (515 y) during winter and spring and in a setting of
crowding and close contact. Person-to-person spread by
means of respiratory droplets is the most common mode
of transmission.
The incubation period for scarlet fever ranges from 12
hours to 7 days. Patients are contagious during the acute
illness and during the subclinical phase.
Scarlet fever / scarlatiniform rash
The rash appears 1-2 days after onset of illness, first on the neck and then
extending to the trunk and extremities.
Scarlatiniform rash
Exanthem texture is usually of coarse sandpaper, and the erythema blanches with
pressure.
The skin can be pruritic but usually is not painful.
A few days following generalization of the rash, it becomes more intense along skin
folds and produces lines of confluent petechiae known as the Pastia sign. These lines
are caused by increased capillary fragility.
The rash begins to fade 3-4 days after onset, and the desquamation phase begins. This
phase begins with flakes peeling from the face. Peeling from the palms and around the
fingers occurs about a week later and can last up to a month.
TX
Treat patients with a standard 10-day course of penicillin or erythromycin. This
regimen prevents acute renal failure if antibiotics are initiated within 1 week of the
onset of acute pharyngitis
Centor Criteria

4. No “cold” symptoms (ie no cough or runny nose)
? (Hint – Not E.T.’s Finger)
Clubbing of Finger/Cystic fibrosis
Background: Cystic fibrosis (CF) is the most common lethal inherited
disease in white persons. CF is an autosomal recessive disorder, and most
carriers of the gene are asymptomatic. CF is a disease of exocrine gland
function, involving multiple organ systems and chiefly resulting in chronic
respiratory infections, pancreatic enzyme insufficiency, and associated
complications in untreated patients. Pulmonary involvement occurs in 90% of
patients surviving the neonatal period. End-stage lung disease is the principal
cause of death.
Gastrointestinal tract manifestations (intestinal)
Neonates: Infants may present with intestinal obstruction at birth and a variety of
surgical findings, for example, meconium ileus (7-10% of patients with CF),
volvulus, intestinal atresia, perforation, and meconium peritonitis. Less
commonly, passage of meconium may be delayed (>24-48 h after birth) or
cholestatic jaundice may be prolonged.
Infants and children: Patients present with increased frequency of stools, which
suggests malabsorption (ie, fat in stools, oil drops in stools), failure to thrive,
intussusception (ileocecal), or rectal prolapse.
Stevens-Johnson syndrome (SJS)
Pathophysiology: SJS is an immune-complex–
mediated hypersensitivity disorder that may be
caused by many drugs, viral infections, and
malignancies. Cocaine recently has been added
to the list of drugs capable of producing the
syndrome. In up to half of cases, no specific
etiology has been identified
In 3-15% of cases, patients with severe SJS die
Stevens-Johnson syndrome (SJS)
The 4 etiologic categories are (1) infectious, (2) drug-induced, (3)
malignancy-related, and (4) idiopathic.
Viral diseases that have been reported include herpes simplex virus (HSV),
AIDS, Coxsackie viral infections, influenza, hepatitis, mumps, mycoplasmal
infection, lymphogranuloma venereum (LGV), rickettsial infections, and
variola.
Bacterial etiologies include group A beta streptococci, diphtheria, Brucellosis,
mycobacteria, Mycoplasma pneumoniae, tularemia, and typhoid.
Coccidioidomycosis, dermatophytosis, and histoplasmosis are the fungal
possibilities.
Malaria and trichomoniasis have been reported as protozoal causes.
In children, Epstein-Barr virus and enteroviruses have been identified.
Drug etiologies include penicillins and sulfa antibiotics. Anticonvulsants
including phenytoin, carbamazepine, valproic acid, lamotrigine, and
barbiturates have been implicated. Mockenhapupt et al stressed that most
anticonvulsant-induced SJS occurs in the first 60 days of use. In late 2002,
the US Food and Drug Administration (FDA) and the manufacturer
Pharmacia noted that SJS had been reported in patients taking the
cyclooxygenase-2 (COX-2) inhibitor valdecoxib.
Various carcinomas and lymphomas have been associated.
SJS is idiopathic in 25-50% of cases

TOF
Pulmonary stenosis (a narrowing of the blood
vessel to the lungs)
Overriding aorta (the main blood vessel from
the heart to the entire body is somewhat
displaced)
A ventricular septal defect (hole in the wall
between the lower two chambers of the heart)
Right ventricular hypertrophy (a thick muscle in
the right pumping chamber)
TOF
First presentation may include poor feeding,
fussiness, tachypnea, and agitation.
Emergency Department Care:
The ED physician should be able to recognize and treat a hypercyanotic episode as one of the
very few pediatric cardiology emergencies that may present to the ED.
Hypoxic tet spell: Hypercyanotic episodes are characterized by paroxysms of hyperpnea,
prolonged crying, intense cyanosis, and decreased intensity of the murmur of pulmonic
stenosis.
Mechanism - Secondary to infundibular spasm and/or decreased SVR with increased right-to-left
shunting at the VSD, resulting in diminished pulmonary blood flow
If left untreated, may result in syncope, seizure, stroke, or death
Treatment for the acute setting of hypercyanosis includes the
following:
Knee-chest position: Place the baby on the mother's shoulder
with the knees tucked up underneath. This provides a calming
effect, reduces systemic venous return, and increases SVR.
Oxygen is of limited value since the primary abnormality is
reduced pulmonary blood flow.
Morphine sulfate, 0.1-0.2 mg/kg IM/SC, may reduce the
ventilatory drive and decrease systemic venous return.
Phenylephrine, 0.02 mg/kg IV, is used to increase SVR.
Treat acidosis with sodium bicarbonate, which may reduce the
respiratory center stimulating effect of acidosis.
General anesthesia is a last resort.

History:
IM may have a varied clinical presentation, but the
symptoms usually consist of fever, pharyngitis, and
lymphadenopathy.
The incubation period of IM is 4-6 weeks. Patients
usually do not recall a history of possible exposure.
Prodromal symptoms consisting of 1-2 weeks of
fatigue, malaise, and myalgia are common
In more than 90% of cases, IM is secondary to EBV
infection
Infectious mononucleosis - Labs
Liver function tests (LFTs) are abnormal in more than 90% of
patients with IM.
Serum transaminase and alkaline phosphatase levels usually are
modestly elevated.
The serum bilirubin may be increased in approximately 40% of
patients, but jaundice only occurs in approximately 5% of IM
cases.
CBC : differential that demonstrates greater than 50% lymphocytes,
an absolute lymphocyte count greater than 4500, or an elevated
lymphocyte count with greater than 10% atypical lymphocytes
Also can have thrombocytosis
Splenic rupture is a serious complication of IM, but it occurs in
fewer than 0.5% of cases. More than 90% of splenic rupture cases
occur in male patients.

Oral thrush
Signs and symptoms
Oral thrush usually produces creamy white
lesions on your tongue and inner cheeks and
sometimes on the roof of your mouth, gums and
tonsils. The lesions, which resemble cottage
cheese
Rubella/German Measles
Background: The name rubella is derived from a Latin term
meaning "little red." Rubella is generally a benign communicable
exanthematous disease.
The major complication of rubella is its teratogenic effects when
pregnant women contract the disease, especially in the early
weeks of gestation. The virus can be transmitted to the fetus
through the placenta and is capable of causing serious congenital
defects, abortions, and stillbirths
Rubella
Incubation period: The incubation is usually 14-21
days after exposure to a person with rubella.
Prodromal phase: Prodromal symptoms are unusual
in young children but are common in adolescents
and adults.
Rubella
The following signs and symptoms usually appear 1-5 days before the
onset of rash:
Eye pain on lateral and upward eye movement (a particularly
troublesome complaint)
Conjunctivitis
Sore throat
Headache
General body aches
Low-grade fever
Chills
Anorexia
Nausea
Tender lymphadenopathy
Sturge-Weber Syndrome
Sturge-Weber syndrome is a neurological
disorder indicated at birth by seizures
accompanied by a large port-wine stain
birthmark on the forehead and upper eyelid of
one side of the face.
Some children will have developmental delays
and mental retardation; most will have glaucoma
(increased pressure within the eye) at birth or
developing later.

Eczema / Atopic Dermatitis
The most common surgical cause of vomiting in
infancy is
a. Intestinal atresias
b. Malrotation
c. Pyloric stenosis
d. Meconium ileus
Pyloric Stenosis
Pathophysiology: Marked hypertrophy and hyperplasia of the 2 (circular and
longitudinal) muscular layers of the pylorus occurs, leading to narrowing of the
gastric antrum.
Frequency:
In the US: The incidence of IHPS is 2-4 per 1000 live births
Sex: IHPS has a male-to-female predominance of 4:1, with 30% of patients
with IHPS being first-born males
Age: The usual age of presentation is approximately 3 weeks of life (1-18 wk).
History:
Classically, the infant will have nonbilious vomiting or
regurgitation,
which may become projectile (up to 70%), after
which the infant is still
hungry.
Emesis may be intermittent or occur after each feeding

Question #1
A 1-week-old infant presents for his first newborn evaluation. He had been
discharged apparently well and thriving at 48 hours of age. He now exhibits
grouped vesicles on an erythematous base that were not present at birth.
Wright stain of scrapings from the floor of the vesicles reveals multinucleated
giant cells and balloon cells.
Of the following, the MOST likely diagnosis is:
A) bullous impetigo
B) congenital varicella
C) herpes simplex virus infection
D) incontinentia pigmenti
E) recessive dystrophic epidermolysis bullosa
