Q

What is the normal cut off for weight loss that should occur during the first week of a child’s life?

A

They should not lose more than 10% of their birth weight in the first week, and this weight should be regained again by day 14

Q

Describe the breast feeding hormone reflex

A

AP produces prolactin
PP produces oxytocin

suckling stimulates the AP and PP

Prolactin causes alveolar cells to make milk, and oxytocin lets the milk ‘down’
Baby then suckles and the breast is emptied

FIP (feedback inhibitor polypeptide) is released when the baby is not suckling which inhibits the alveolar cells from making milk

Q

Describe the pathophysiology of CF

A

Normal CFTR protein = allows chloride ions to leave mucosal cells and enter the lumen of organs
Defective CFTR = chloride ions cannot leave mucosal cells which leads to thickened, sticky secretions which cannot be cleared

Affects many organ systems:

  • lungs
  • pancreas (exocrine deficiency)
  • liver (fibrosis and thick bile)
  • reproductive system (non-functioning vans deferens and thickened cervical mucous)
  • poor growth and delayed puberty

Q

Describe CF screening

A

Look for raised IRT (immunoreactive trypsin levels) on neonatal blood spot -> as the pancreatic duct shrivels up antenatally this means that enzymes get backed up into the blood

Q

Describe the differences between foetal and adult circulations AND what happens when the baby is born

A
  1. Ductus venosus - carries nutrient rich, oxygenated blood straight from the mother’s placenta to the foetal inferior IVC and into the RA of the heart (bypassing the liver)
  2. Foramen ovale - allows blood to pass RA -> LA (bypassing the lungs which are not yet functioning)
  3. Ductus arteriosus (becomes ligamentum arteriosum) - allows any blood which does pass into the RV and pulmonary artery to move straight from PA -> aorta (avoiding the lungs)

When baby takes first breath, this reduces pulmonary vascular resistance, there is an increase in LA filling as blood is returning from the now functioning lungs and the foramen ovale closes.

Q

What is transient tachypnoea

A

Normally during labour the infant’s chest is squeezed as it passes through the birth canal and this helps to clear fluid from the lungs, however often infants can suffer from transient tachypnoea following a C-section when their lungs have not been squeezed as it can take several hours for the lung fluid to be resorbed, resulting in laboured & rapid breathing.

Q

Describe respiratory distress syndrome

A

Deficiency of surfactant, often in premature babies, lowers surface tension leading to widespread alveolar collapse and inadequate gas exchange
Common in infants born < 28 weeks as type 2 pneumocytes have not secreted enough surfactant, rare at term but may occur in infants of DIABETIC mothers
Clinical signs = >60 breaths/min, laboured breathing

Q

Describe the common pathogens that can cause early and late onset infections in newborn infants

A
  1. Early onset sepsis (within 48hrs of birth)
    Usually due to bacteria which ascended the birth canal and entered the amniotic fluid. Caused by E.COLI and mother may have fever during labour. Presents with resp distress, apnoea and temperature instability
  2. Late onset sepsis (>48hrs from birth)
    Nosocomial or environmental infections
    STAPH EPIDERMIS is the most common pathogen in NICU from indwelling catheters
  3. GROUP B STREP can cause LATE AND EARLY infection
    20% of women have vaginal carriage of this bug

Q

Describe the neonatal resus flow chart

A
  1. As soon as baby is born, it will sit on mother for 1 minute and start the timer on the resuscitaire (delayed cord clamping occurs
  2. Baby is then brought over to resuscitaire and stimulate with towel for a few seconds
  3. Assess tone, breathing and HR
  4. If not breathing/gasping -> give 5 inflation breaths (3 seconds long) and LOOK FOR CHEST MOVEMENT
  5. If still not good chest movement, consider 2 person technique and repeat the 5 inflation breaths
  6. Once chest is moving, assess HR (if <60 then provide ventilation breaths, if >60 then ask senior!) -> may needs sats probe and tailored O2 etc.
56
Q

Describe the components of the APGAR score

A

Appearance (blue/pink with blue extremities/pink)
Pulse (absent/<100/>100)
Grimace (floppy/minimal response to stimulation/maximal response to stimulation)
Activity = ‘muscle tone’ (absent/flexed arms and legs/active)
Respiration (absent/slow and irregular/vigorous cry)

57
Q

Define the cut off for neonatal jaundice and list 3 reasons why newborns can become visibly jaundiced:

A

Serum bilirubin >85umol/L

  1. Shorter RBC lifespan (70 days not 120) therefore more breakdown and Hb production
  2. Newborns have a lot of RBC’s!
  3. Hepatic bilirubin metabolism (converting UC -> C) is less effective in the first few days of life
58
Q

Define ‘prolonged jaundice’ and what can cause it

A

Prolonged = >14 days in a term infant and >21 days in a preterm infant

The commonest cause of prolonged jaundice is breast feeding (mechanism unclear, but thought to be due to increased enterohepatic circulation of BR)

59
Q

List causes of 1) unconjugated, 2) conjugated hyperbilirubinaemia

A

1) Unconjugated = most common type, caused by:
- haemolytic disease (ABO incompat, Rh factor)
- physiological
- breast feeding
- hypothyroidism
- infection (sepsis/UTI)

2) Conjugated = rarer, but most common cause to rule out is BILIARY ATRESIA

60
Q

What complication can occur with unconjugated hyperbilirubinaemia?

A

Unconjugated BR can be deposited in the brain causing kernicterus (encephalopathy, as bilirubin is neurotoxic and can present with lethargy and poor feeding, occurs when serum BR levels >400umol/L)

61
Q

How is neonatal jaundice treated?

A

1) Phototherapy using 450nm wavelength of light (converts the UCBR into soluble pigment which can be excreted)
2) Exchange transfusion

62
Q

List the top 5 causes of respiratory distress in the neonate

A

Ask parents to clean the perineum of the infant or child (from front to back)
Should be a “clean catch” into a foil dish- no touching the inside of the dish
Then decanted into a urine pot

73
Q

Why might nitrites not be present in the urine sample of infants <1yr?

A

74

A

Dilute urine

75
Q

List indications for using a peak flow meter

A

Diagnostic
Monitor response to treatments
Marker of severity in exacerbations

76
Q

Counsel how to use a peak flow meter

A

Set the counter back to zero before starting
Hold so that your fingers don’t obstruct the dial (from beneath/both hands)
Sit up straight/perform standing
Take a breath in to completely fill your lungs
Make a good seal on the mouthpiece, make sure teeth/tongue aren’t in the way
Blow out into the peak flow as hard and as fast as you can
Look at the counter after you perform the test (make a note)
You usually Take the best of 3 goes.

You should ensure that their technique is good enough that the repeatability of the best 2 are within 10%.

77
Q

Counsel how to use an inhaler + spacer

A

Shake well before use
Remove cap
Check expiry date on the inhaler
Prime before first use/if not used for weeks (with one puff)
Keep chin up and create tight seal
Breathe out before using
Breathe in over 2-4 seconds starting as you deliver the puff
Give enough time for inhaler to reset (at least 30 seconds!) before next puff (5-10 breaths in a spacer). Breaths MUST be slow to ensure the drug doesn’t hit the back of the throat and you get optimum delivery to the lungs.

If using a steroid inhaler can advise using just before brushing teeth in morning/evening

We would never advocate using a MDI (metered dose inhaler) without a spacer. Only if there wasn’t one available, but we would always encourage them to have one with their Salbutamol. (Use spacers up to ~5yrs old)

78

A
DMD = duchenne muscular dystrophy (x-linked recessive - only M affected!- show's Knight's move inheritance where a carrier mother with an affected father passes the disease onto her son)
BMD = Becker's muscular dystrophy

DMD = out of frame mutation in the DMD gene which means abnormal ‘dystrophin’ protein is made, which usually acts as an intracellular linking protein for fibrin molecules -> this means that muscles cannot contract properly

BMD = less severe as it is an ‘in-frame’ mutation, so muscle weakness is not as severe
