diagnosis of asthma
clinical symptoms
Fev1:FVC <70%
bronchodilator reversibility
management of asthma
STEPWISE
1) inhaled SABA PRN- Beta 2 agonist eg salbutamol
2) inhaled steroid daily- low dose bethamethasone
3) add LABA- salmetarol
4) increased steroid dose
5) oral steroid- prednisolone
acute asthma attack management
Escalate as neccessary: ABCDE High flow O2 salbutamol nebuliser IV hydrocortisone/ prednisolone IV magnesium sulphate Ipratropium bromide nebuliser IV aminophylline HDU
cystic fibrosis gene defect and diagnosis (x3)
autosomal recessive defect of CTFR gene on Ch 7
Diagnosis:
- Gutherie heel prick- raised immunoreactive trypsinogen
- sweat test- raised chloride ions
- low faecal elastase
presentation fo CF in infancy
meconium ileus (vomitting, abdo distension, failure to pass meconium) FTT steatorrhoea malabsorption recurrent chest infections prolonged neonatal jaundice
name a mucolytic drug
carbocysteine
<1yo
regurgitation, distress after feeds, apnoea, aspiration pneumonia, FTT, food aversion, infant ‘spells’- seizure like, haematemesis
Investigations to diagnise
GORD
Investigations:
sometimes endoscopy and measure pH
PPI test- give antacids + symptoms improve
presentation of pyloric stenosis
metabolic disturbance
2-7 weeks of age males>females PROJECTILE VOMMITTING- increasing frequency and force. Not bile stained, no diarrhoea hunger weight loss
Hypochloraemic, hypokalaemic metabolic alkalosis
diagnosis and management of pyloric stenosis
diagnosis
-test feed and ultrasound- see L–>R peristalisis and olive shaped pyloric mass
management
- IV fluids
- pyloromyotomy
intersussuption presentation
3mo-2 years boys>girls
paroxysmal abdo colic pain, knees drawn up to chest, pale, screaming in pain
vomiting- may be billious
mucus and blood in stools- RED CURRENT JELLY STOOL
RUQ abdo mass- SAUSAGE SHAPED
Intersussuption investigations and treatment
investigations
- ultrasound abdo: doughnut shape
- X ray: distended small bowel and absence of gas in large bowel
Treatment
Fluid resus
rectal air enema
surgical intervention
Necrotising enterocolitis presentation
Management
PREMATURE BABIES
1st few weeks of life
abdo distension, pain, fresh blood in stools, billous vomitting, feeding intollerance
risk of progressing quickly to abdominal discolouration, perforation and peritonitis.
fed with cows milk increases risk
Xray showing gas in gut wall pathomneumonic= pneumatosis intestinalis
also asymetrical dilated bowel loops, bowel wall oedema
MANAGEMENT
Stop feeding, Abx, parenteral nutrition, surgery if perforation
Presentation of coeliac disease
Diagnosis
Management
= gluten intollerance causing enteropathy (villous atrophy and crypt hyperplasia)–> malabsorption
2yo, failure to thrive following introduction of cereals into diet
general irritability, diarrhoea, abdo distension and buttock wasting, anaemia
DIAGNOSIS
Jejunal biopsy- flat mucosa
gluten withdrawal–> symptom resolution
Serological tests- IgA and endomysal antibodies
Gluten free diet
Presentation of Hirschsprungs disease
presentation
Investigation
=congenital absence of ganglia in segment of colon- poor innervation of bowel
CONSTIPATION
failure to pass meconium within 48 hours of life
older children- abdo distension and constipation
common in DOWNS and M>F
investigations
PR exam- causes explosive discharge of stool and gas
List some causes of jaundice
a) in first 24 hrs of life
b) 24hrs-2weeks of life
c) Prolonged
<24 HOURS
- haemolytic disorders- rheusus (coombes test +ve)
- congenital infections- syphilis, herpes, rubella
24 HOURS- 2 WEEKS
- physiological- as fetal RBC lifespan shorter than adults and hepatic bilirubin metabolism less efficient
- breast milk jaundice
PRLONGED- SERIOUS
- infection-sepsis
- hypothyroidism
- billary atresia
- CF
- Hepatitis
complication of jaundice
Kernicterus
Bilirubin crosses blood brain barrier–> deposited in basal ganglia- neurotoxic- encephalopathy
seizures, learning difficulties, cerabal palsy, death
Signs of dehydration
