Objectives

• Key in on irritability as an important patient/parent complaint

• Develop a differential diagnosis for this complaint

• Review some of the common entities that cause irritability

Case 1

• A 5 week old is brought to the ED for the problem of irritability. The child was full term product of vaginal delivery without complications. The child has periods of screaming that the parents cannot quiet. She draws her legs up and passes gas. She is growing and appears to be gaining weight. This happened the last three nights.

Case 1

• T 37 C P130 R 40 Wt. 4.2 K

• A well nourished, well developed baby with round cranium, open flat fontanel.

• HEENT – negative

• Chest – clear breath sounds

• Heart – regular rhythm no murmur strong pulses

• Abdomen – no organ increase, soft, non tender, normal bowel sounds

Case 1

• Neurological – normal

• Skin – no bruises, no rash

Are there any other parts of the exam you wish to check?

What is your diagnosis?

How will you instruct the parents?

Differential Diagnosis

• Colic

• Crying with Cause

– Skin –rash, hair tourniquet

– GU – torsion, hernia, UTI

– CNS – infection, anomaly

– Musculoskeletal – fracture

– HEENT- corneal abrasion, otitis, glaucoma

– Drugs - Electrolyte

Parental Instruction

• Colic

– Babies have to cry

– Avoid over-feeding

– Avoid over stimulation

– Saying “it will get better” does not help

Case 2

• A 12 month old child is brought in for 8 days of fever and irritability. The child has been seen by his pediatrician three times. The last visit two days ago resulted in the diagnosis of otitis media and the child started on Amoxicillin. There has been no improvement. The child is still febrile and irritable.

– (Irritability per Ludwig)

Case 3

• A two year old has been irritable and asking the mother to hold her. She has had fevers on and off. The parents noted that she did not want to walk today. They have seen a rash off and on that think is eczema. The child has been growing well and has normal development.

Case 3• What diagnoses are you considering?

• What laboratory tests would you order first?

• Are there procedures you would perform in the ED?

Juvenile Idiopathic Arthritis

• Heterogeneous group of illnesses – genetic and environmental causes 1:1000

• Several Forms – oligo articular-polyarticular – systemic- enthesitis

• Systemic -first 6-18 months spiking fever, irritability, rash

• May start with very subtle symptoms-check all joints

• Carditis, MAS, and other complications

Case 4

• A three year old is brought in for extreme irritability. The only thing the parents note is that she has had a cold recently with cough, rhinitis and low grade fever. They heard her crying in her bed and found her hysterical. They rushed her to the ED when they could not calm her.

Case 4

• Out of control child - screaming and thrashing about.

• As best as you can obtain T 37 C, P 150, R 30 BP 138/78 O2 Sat 70-97%

• Examination is difficult but there appear to be no localized findings.

• She continues to seem very frightened and out of control

Case 4• What is going on?

• How should you manage her behavior?

• Are there labs that will help you?

• Should you bring in the psychiatrist

Night Terrors

• “Temporary insanity”

• Look awake but not awake

• Abrupt onset from sleep

• Brought to ED

• Often follows a disruption in routine

• Return the child to sleep and they awake in their pre-morbid personality

• Heart - regular, tachycardia, no murmur

Case 5

• Abdomen - soft, non tender

• GU - normal

• Skin - bruise on L pinna

• Extremities - becomes very irritable when performing Kernig’s and Brudzinski’s. Falls asleep when left alone, cries when stimulated

Case 5

• What else is important to know in the history?

• What labs would you order and why?

• Anything else that might help you?

Non Accidental Trauma

• Child abuse

• Many different forms

• Very common

• Keep in mind for things that are hard to reconcile and understand

Case 6

• A three month old is referred from the pediatrician’s office for crying. The doctor reports that every time the child tries to nurse, he cries and refuses to drink. This has been happening off and on for awhile but today it is constant. Only past history is four episodes of wheezing

• Remainder of the PE is also normal except that you note intermittent posturing during your exam.

• The child can not sit alone and does not crawl.

Case 6

• What is your differential diagnosis list?

• Are there any labs you need?

• What would you do next?

• Should you admit this child?

Gastroesophageal Reflux GER

• Common but not always associated with pain and irritability

• Several modalities to use in making diagnosis

• Treatments also vary with severity of involvement

• Weight and response to acid blockers are good triage points

Case 7

• A one and one half year old has had irritability all day. Intermittently she screams out as if in pain. She has vomited once and has refused to eat or drink anything. She has no fever and no other symptoms.

• PMH, SH, FH are all negative.

• GU - negative

• Rectal - stool present no blood

• Skin - bruise like lesions on lower extremities

Case 7

• During your exam the child screams in pain and is inconsolable. She draws her legs up in flexion.

• What are you considering as to cause?

• What will you do next?

Intussusception• 3 months to 3 years but can be any age

• Primary – due to hypertrophy of Peyer’s patches in terminal ileum – ileo-ileal

• Secondary to Meckel’s, HSP. CF., Celiac

• Air enema predominant method of reduction

• U/S good diagnostic accuracy

• Irritability mixed with lethargy

Case 8

• HEENT - negative

• Chest - lungs clear Heart - regular tachycardia

Case 8

• Abdomen -negative

• GU - negative

• Extremities - normal

• Skin - normal - well perfused - no rash

• Neurologic - as described above

Case 8

• What is your next step?

• What are you considering?

• Are there tests to order?

Corneal Abrasion

• Topical anesthetic important

• Rule out ruptured globe

• Fluorescein papers

• If large and in visual axis refer to ophthalmologist

• Vertical abrasion – r/o FB

• Most heal within 24 hours.

• Irritability relieved by closing the eye

Summary

• The irritable child can pose diagnostic challenges

• Often details of the history are important such as acute or chronic, timing of onset of symptom, other physical finding

• What relieves the irritability is another good clue.
