Endocrine Flashcards
Which measurements are essential for assessing growth?
- Length/height
- Weight
- OFC
- Bone age
- Pubertal assessments
- MPH and target gentiles
- Growth charts and plotting
Short stature for age aetiology
- FH
- Constitutional
- SGA/IUGR
Pathological •Undernutrition •Chronic illness (JCA, IBD, Coeliac) •Iatrogenic (steroids) •Psychological and social •Hormonal (GHD, hypothyroidism) •Syndromes (Turner, P-W)
What investigations would you do for short stature?
- FBC and ferritin
- U&Es
- LFTs
- Ca
- CRP
- Coeliac serology and IgA : Coeliac disease
- IGF-1, TFTs, prolactin, cortison : Hormonal disorders
- Karyotype : Tuner’s syndrome
Tanner method
B: breast development 1-5 G: genital development 1-5 PH: pubic hair 1-5 AH: axillary hair 1-3 T : testes 2 ml to 20ml
What do you use to assess testicular size?
ORCHIDOMETER
Normal pubertal development in girls
Breast budding at 10-11
Early breast development 12-13
When do girls stop growing?
Once they have got their first menstrual period
Normal pubertal development in boys?
- Boys get growth spurt later
- Onset of testicular growth is about 13
Early and delayed puberty in boys and girls
•Boys –early < 9 years (rare) –delayed >14 (common, especially CDGP) •Girl –early <8 years –delayed >13 (rare)
Delay of growth in puberty
- Mainly boys
- FH
- Bone age delay
- Need to exclude organic disease
Other
- Gonadal dysgenesis e.g. Turner 45X
- Chronic disease e.g. Crohn’s/ Asthma
- Impaired HPG axis e.g. Kallman’s syndrome
- Peripheral e.g. cryptoorchidism, Testicular irradiation
What do you need to exclude in ambiguous genitalia?
Congenital adrenal hyperplasia
There is an adrenal crisis risk at 2 weeks of life
Diabetes symptoms
- Thirsty
- Thinner
- Use toilet more
- Tired
Approach to suspected case diabetes
- Finger prick capillary glucose test
- If result over 11mmol/l then call specialist team
Red flags of DKA
- Nausea and vomiting
- Abdominal pain
- Sweet smelling breath
- Drowsiness
- Rapid, deep “ sighing” respiration
- Coma
Main causes for obesity?
- Simple obesity
- Drugs
- Syndromes
- Endocrine disorders
- Hypothalamic damage
What is an abnormal presentation in obesity?
SHORT + OBESE
Treatment for obesity?
- Diet
- Exercise
- Psychological imput
- Drugs- not much use
When to suspect Acquired hypothyroidism in children
–Lack of height gain
–Pubertal delay (or precocity)
–Poor school performance (but work steadily)
Manifestations of early sexual development?
Breast development
- Infantile thelarche
- Central precocious development
Sexual secondary characteristics ( sex steroid, hormone secretion)
- Exaggerated adrenarche
- Precocious pseudo puberty a.k.a congenital adrenal hyperplasia
PV bleeding: premature menarche
Presentation of central precocious puberty
- Growth spurt
- Advanced bone age
- Pubertal development
- Abnormal sex steroid secretion
What do you need to exclude in central precocious puberty?
- congenital adrenal hyperplasia
- pituitary lesion– MRI
