Overview of Zika in the US Virgin Islands

•Jan 25, 2016 the first laboratory confirmed case in the US Virgin Islands

•37,000+ positive tests for Zika virus in the U.S. territories •~4500 are pregnant women •~290 infants born to Zika positive mothers in the U.S. Virgin Islands in the last 2 years

HOW TO PERFORM A NEUROLOGICAL

EXAMINATION IN INFANTS AND CHILDREN WITH

CONFIRMED OR SUSPECTED ZIKA VIRUS

• Apply the major components of the infant/child neurological examination.

• Record the infant’s or child’s responses.

• Recognize the neurological signs of congenital Zikasyndrome

• Anticipate neurological complications in infants with neurological signs consistent with congenital Zika syndrome

NEUROLOGIC EXAM COMPONENTS

• General observation• Mental State• Cranial Nerves• Motor

– Tone– Strength– Movement

• Reflexes– Deep tendon reflexes– Plantar reflexes– Primitive reflexes

• Sensation• Head size, shape and

fontanels/sutures

OBSERVATION AND MENTAL STATE

• Observe the infant or child. Is he/she awake or asleep? Is she/he quiet or irritable? Does the child make eye contact? Does the child respond to you or the parents?

• If the child is feeding, does he/she hold a bottle?Can the child pick up food?

• Does the child vocalize or say words? Can the child reach for or hold a toy? Does the child show handedness? Does the child sit or walk?

CRANIAL NERVE EXAMINATION OF

INFANTS

• Observe the infant during the awake state.

• Are the pupils equal and reactive? Are the red reflexes present bilaterally?

• Does the infant open the eyes spontaneously and have full eye movement in all directions?

CRANIAL NERVE EXAMINATION OF

INFANTS

• Does the infant hear?

• Does the infant display spontaneous and symmetrical facial movements?

• Does the infant suck and swallow appropriately when nursed or bottle fed? Is a gag present?

CRANIAL NERVE EXAMINATION OF

YOUNG CHILDREN

• CN II: Are the pupils equal and reactive? Are the red reflexes present and equal bilaterally?

• CN III, IV, VI: Does the child follow an object, such as a toy or flashlight?

CRANIAL NERVE EXAMINATION OF

YOUNG CHILDREN

• CN VII: Does the face movesymmetrically?

• CN VIII: Does the child hear?

• CN IX, X: Does the childsuck and swallow? Is a gagreflex present?

• CN XI: Can the child move the head to each side?

• CN XII: Does the tongue protrude normally?

MOTOR EXAMINATION IN INFANTS

• Is the infant’s posture appropriate for the gestational age? Are the arms and legs flexed if full term, extended if preterm?

• Does the infant move all extremities spontaneously?

MOTOR EXAMINATION IN INFANTS

• Assess flexor and extensortone at all joints.

• Assess head control and response to ventral suspension.

MOTOR EXAMINATION IN INFANTS

AND YOUNG CHILDREN

• Assess tone by observation as well as by passive or active movement.

ASSESSING DEEP TENDON REFLEXES

IN INFANTS AND CHILDREN

• Assess deep tendon (aka “muscle stretch”) reflexes at the biceps, brachioradialis, patellar and Achilles tendons. Grade 0 to 4 based on responses (0 = absent; 4 = clonus).

REFLEXES

• Assess the infant’s response to the Moro reflex. Are arm movements present, symmetrical, and full (displaying both extension and flexion)?

• Does the infant have symmetrical palmar and plantar grasp responses?

• Plantar reflex: an ‘up-going’ toe is typical until 9 -12 months of age

SENSATION

• Assess the response to touch, tickle and mild pain in all four extremities

TODDLERS

HEAD SHAPE AND MEASUREMENT

Adapted from Danmar Co., helmet sizing

PLOT THE INFANT’S HEAD

CIRCUMFERENCE ON A STANDARD

GROWTH CURVE• Head circumference is also

known as occipital-frontal circumference or OFC.

• Microcephaly = OFC <3rd

percentile.

• Normal OFC varies according to gestational age and gender.

• For a term infantmicrocephaly corresponds toan OFC of <32 cm.

ABNORMAL HEAD SIZE

Microcephaly Macrocephaly

CRANIAL SUTURES

Sagittal suture synotosis Metopic suture synostosis

POTENTIAL ABNORMAL SIGNS IN

CONGENITAL ZIKA SYNDROME

• Microcephaly: measure and plot the infant’s head size.

• Chorioretinitis, optic atrophy: perform a retinal examination.

• Hearing loss: obtain the newborn hearing screen, usingotoacoustic emissions and automated auditorybrainstem response by 1 month of age.

• Abnormal muscle tone (spasticity, rigidity, hypotonia): perform a complete motor examination, assessing tone at all extremities.

• Congenital contractures, arthrogryposis multiplex congenita: observe posture, assessing range of motion at all extremities.

FOLLOW-UP FOR INFANTS WITH

CONGENITAL ZIKA SYNDROME

• Enroll infants in early intervention programs, including physical and developmental therapy.

• Refer infants for neurodevelopmental assessment.

• Head ultrasound, ophthalmology examination and hearing assessment (ABR) by 1 month of age.

FOLLOW-UP FOR INFANTS WITH

CONGENITAL ZIKA SYNDROME

• Monitor for seizures, including subtle or electrographic seizures in newborns and infantile spasms in infants 3 to 10 months ofage. An EEG may be necessary.

• Consider a brain MRI.

• Provide psychosocial support to parents andother family members.

AGE-APPROPRIATE DEVELOPMENTAL

SURVEILLANCE AND SCREENING FOR CHILDREN

WITH CONFIRMED OR SUSPECTED ZIKA VIRUS

• Developmental milestones should be assessed at each well child visit

• Four areas:

1. Gross Motor

2. Fine Motor

3. Language

4. Social

https://www.cdc.gov/ncbddd/actearly/milestones-app.html

GROSS MOTOR

• Control develops headto toe, as myelinationprogresses– Head control (no head

lag): 1-2 months

– Upper extremity (lifts chest up): 2-4 months

– Truncal control (sits onown): 5-6 months

– Lower extremity (supports weight standing): 9-11 months

FINE MOTOR

• Progresses from proximal to distal– Involuntary grasp (reflex)

▪ 0-1 month

– Hands to midline▪ 2-4 months

– Bring objects to body▪ 4-5 months

– Transfer between hands▪ 5-7 months

– Immature pincer grasp▪ 9 months

– Mature pincer grasp▪ 12 months

LANGUAGE-EXPRESSIVE

• Ability to producelanguage

• Cooing: 2-3 months

• Babbling (consonants +vowels): 6 months

• Jargon (intonation): 9-12 months

Bing images

LANGUAGE-RECEPTIVE

• Ability to comprehend language

• Startles to voice: at birth

• Turns head to sound: 4 months or more

• Responds to selective words (“no”): 9-12months

• Follows 1 step commands: 12-18 months

• Parental attachment: 6-8 months

• Stranger anxiety: 9-12months

• Pretend/parallel play: 2years

• Group play: 3 years

PERFORM AGE APPROPRIATE

DEVELOPMENTAL SCREENING

• Screening can help identify children with developmental disabilities

• Without screening, 70% of children with developmentaldisabilities may not be identified (Palfrey et al, 1994).

• Surveillance at every well child visit, developmental screening at each well child visit, autism screening at 16 months and older, behavioral/emotional screening annually

• Screening mechanisms:

– Provider exams– Parent/patient questionnaires

https://www.cdc.gov/ncbddd/actearly/ milestones/milestones-18mo.html

AGES AND STAGES QUESTIONNAIRE

(ASQ)• Developmental screening at each well child visit.

• Parent administered survey

• Screens multiple domains (communication, gross and fine motor, problem solving and social)

• Sensitivity 70-90% Specificity 76-91%

• Written at 4th grade literacy

• Available for multiple ages (if children miss a WCC visit for the recommended screening)

• Scored 10 points (always), 5 points (sometimes), 0 points(never)

M-CHAT (MODIFIED CHECKLIST

FOR AUTISM)

• Autism Screening at 16 months

• Parent completed or administered verbally

• Sensitivity 85% Specificity 93%

• PPV 36%

• There are f/u questions for Fails and f/u interview to improve specificity BUT about 50% of those who screen positive will not have ASD- some may have language, cognitive delays
