Paediatric Medicine π§π» Flashcards
Diagnosis of T1 DM
Random blood glucose above 200 and symptoms. Need two readings if asymptomatic. Or fasting above 126
Potential antibody testing for T1 DM patients
Anti GAD, anti islet cell,
Other than insulin, what management should we give to diabetics (T1)
Routine screening and do Vxβs
First invx for DKA
Glucose test
General invx for DKA aside from glucose
ABG, urinalysis, workup for cause
Name as many reasons when you would consider an ICU transfer in DKA
Ketone > 6
HCO3 < 5
pH < 7
K < 3.5
GCS < 12
O2 < 92%
SBP < 90
AG > 16
(HOPAKS slava ukarini)
Management of DKA
Fluid resus (isotonic), insulin, K+ due to risk of hypokalemia when admin insulin, IV HCO3 in severe met ac.
Hypoglycaemia level in diabetics vs non diabetics
Diabetics: <70
Non diabetics: <55
Whipple triad for hypoglycemia
Low glucose, signs of low glucose, relief of symptoms when eat glucose
Neurogenic/autonomic hypoglycaemic symptoms
SNS signs, tremor, pallor, tachycardia, sweating, palpitations.
PNS signs, hunger, parenthesia, N/V
Neuroglycopenic hypoglycaemic symptoms
Agitated, confused, AMS, fatigue, seizure, somnolence (coma and death)
First Invx for hypoglycemia
Glucose test
Mx of hypoglycemia (if alert, if AMS)
If alert: oral glucose/fruit juice etc.
If AMS: IV dextrose (may need multiple doses). IM glucagon if no IV access
After treated hypoglycemia, how to Invx? (Diabetic vs non diabetic patient)
Check for acute illness, review meds if diabetic.
Labs, CXR, urinalysis, insulin, c peptide levels if no obvious cause.
Is pregnancy still possible in Turners
Yes, with IVF, using donor oocytes and exogenous estradiol/progesterone
3 elements to the diagnosis of Turners
Clinical. Low E. High FSH. Karyotype to confirm
Two hormone therapies for Turners, and one important surgery
Estrogen/progesterone Tx, GH Tx, remove streak gonads
EEG for absence seizures
3Hz spikes in all regions of the brain
1st line for absent seizure
Ethosux (2nd line: valproate )
3 main types of cerebral palsy (based on brain location affected)
Spastic (motor cortex), Dyskinetic (basal ganglia), ataxic (cerebellum)
Main risk factor for cerebral palsy
Preterm and low birth weight
Hand preference before age 1β¦ is this a red flag for what?
Hemiplegia
How to diagnose cerebral palsy
Itβs a clinical diagnosis. Consider cranial US in neonates and MRI in older infants (see haemorrhage, hypoxia, periventricular leukomalacia)
Cure for Cerebral Palsy?
No. Just improve QoL
Mx for cerebral palsy
Therapy (physical, occupational, speech, educational, nutritional, social). Antispasmodics (botulinum, baclofen, dantrolene, benzodiazepines).
Most common cause of intellectual disability
Downs
First trimester tests results for downs fetuses
Low PAPP-A, high BHCG, nuchal translucency
Second trimester tests results for downs fetuses
BHCG and Inhibin high
Estriol and AFP low
If screening for downs indicates increased risk, what confirmatory tests can we do?
9-14 wks: Chorionic villus sampling
15-22 wks: amniocentesis
Simple vs complex febrile seizure
Simple: tonic clonic, generalised, less than 15 mins, one in 24 hours
Complex: focal, one side of body, more than 15 mins, more than one seizure in 24 hours. (Complex if 1 or more met)
Aim of diagnostic workup in simple febrile seizure.
Find cause (no specific workup)
diagnostic workup in complex febrile seizure? and the aim?
EEG and imaging needed! To find underlying cause
When do we give abortive therapy for febrile seizure
If complex, or if lasts >= 5 mins. Give IV diazepam
Mainstay treatment for febrile seizure
NSAID/paracetamol to reduce fever
Causes of meningitis if less than 1mo
Strep agalactiae, ecoli, listeria
Causes of meningitis if above 1 month
Strep Pneumoniae, neisseria meningitis, HiB (if unVx)
Symptoms of meningitis in neonates
Very general. Lethargy, hypotonia, vom , poor appetite etc.
Then late on, bulging fontanelle, crying and seizure
Symptoms of meningitis in children
Our classics triad:
Fever
Headache
Neck stiffness
Suspect clinical diagnosis if meningitis. Next thing to do?
Obtain blood culture and LP
Diagnostic test for meningitis
LP and CSF analysis
When does imaging need to be done before LP (use FAILS mneumonic)
Focal neuro
Altered mental status
Immunocomp/ICP high
Lesions
Seizure
Vital treatment for meningitis. Then other Mx
Empiric antibiotics (if LP delayed, give anyway).
Fluids, secure airway if GCS < 8
Age < 1, empiric Tx for meningitis
Ampicillin and Gentamicin
Age > 1, empiric Tx for meningitis
Vancomycin and Cefotaxime/Ceftriaxone
When to give decamethosone when giving treatment for antibiotics?
If suspect strep Pneumoniae or HiBβ¦. Avoid CK storm
Strep Pneumoniae meningitis Abx
Vancomycin
3rd gen cephalosporins can cover which 3 bac meningitis
HiB, Neisseria, Ecoli
Listeria and strep agalactiae meningitis Abx
Ampicillin
status epilepticus definition
Seizure lasting more than 5 mins (Tonic clonic), or sequence of seizures without gap in between. But if focal or absence, needs >10 mins.
Management of status epilepticus
IV benzos, or IM midazolam (if not IV access). Rectal or buccal diazepam are alternatives.
Management of status epilepticus if persistent (20-40mins)
IV fosphenytoin (or valproate, levetiracetam)
Management of status epilepticus, refractory (40-60 mins)
Repeat second lines, or induce coma
Mx of acute airway obstruction. 1st? If doesnβt work emergency measures?
Heimlich if full obs. Endotracheal tube, tracheostomy, Cricothyrotomy. CPR if unconscious
Invx for after an acute airway obs
Bronchoscope, CXR
Invx of acute bronchitis
Clinical diagnosis, can rule out other pathology with CXR, swabs etc.
Mx of acute bronchitis patient
Hydration, rest. Maybe symptomatic relief (paracetamol, antitussive, steroids, expectorants)
Invx for acute pharyngitis
Rapid strep test (and can do the centor score).
M-CENTOR score for strep pharyngitis
M must be older than 3 (3 looks like m)
C cough absent
E exudative tonsils
N node enlargement
T temperature elevation
OR young or old
CENTOR 4 or above
Empiric ABx
CENTOR 2 -4
Rapid test, throat culture
CENTOR 1 or less
No further Invx for strep
Mx for acute pharyngitis
Amoxicillin/clarithromycin for 10 days (recall sign if IM instead)
Diagnostic criteria for anaphylaxis
Mx for anaphylaxis
Epinephrine IM
Diagnosis of bronchiolotitis
Clinical Dx, can do nasopharyngeal swab for RSV (although not often done)
Main management for bronchiolitis
Supportive.
O2 if below 90%, IV fluids, nasal suction. Bronchodilators, steroids for severe encases only.
When do we hospitalise a bronchiolitis patient ?
Toxic, poor feeding, dehydration, respiratory distress, premature Hx, lung or heart disease, immunodef.
Management of mild Croup?
oral Dexamethasone
Management of moderate-to-severe Croup?
Inhaled epinephrine. (Quicker action than dexamethasone. ontop of CSs, IV fluids
Which children require confirmatory testing for CF
If they had positive newborn screening, first degree relative, has CF signs
The confirmatory testing signs of CF. Recall values for chloride
- Sweat test Cl of >60
- CFTR mutations and sweat test Cl >30
- +ve physiological testing
Mx of CF for lung preservation
High dose ibuprofen, bronchodilator, mucolytics, airway clearance technique
Mx of CF for nutrition
High energy diet, CREON, fat sol vitamins, NaCl intake
First thing to do in Epiglottiitis
Secure airway!! Before Invx.
How do we diagnose epiglottitis in acute setting
Clinically
When do we do the lateral cervical X-ray in epiglottitis?
If Dx unclear and patient stable
