Q
What are the 3 main causes of microcytic anaemia?
How is iron absorbed I want 4 steps
A
Iron deficient anaemia (poor intake or absorption i.e coeliac)
Anaemia of chronic disease
Sickle Celled Disease or thalassaemia
- It is absorbed in the duodenum and is AT into the duodenum It is incorporated to make ferritin. The iron that does not bind to the ferritin is released into the blood. This binds to the protein transferrin and is used in the plasma to the bone marrow.
2
Q
What is the clinical presentation of microcytic anaemia?
How do you treat iron deficient
How do you treat of chronic disease (cause IBD, cancer and RA)
A
- Fatigue
- SOB and poor feeding
- Pallor
- Angular stomatitis
- Brittle hair and nails
- Pica: inappropriat eating of non food
Treatment:
- Iron deficient: this is improve diet and give iron tablets
- Chronic disease: give the patient EPO and treat cause
3
Q
What will the blood work in iron deficient anaemia look like?
A
FBC and blood film: will show microcytic and hypo-chromic anaemia
Low serum ferritin
Low reticulocyte count
In comparison with anaemia of chronic disease the serum ferritin will be normal
4
Q
What is the definition of a seizure?
What are 4 Causes of epilepsy?

A
Seizure is when you get a sudden disturbances in the neurological function: due to abnormal neuronal firing.
4 causes of epilepsy:
- Idiopathic
- Malignancy
- Cerebral malformation
- Cerebral vascular event
4 causes of non epilepsy:

Q
What is the inner ear made up of?
A
the hearing and balance organs
This includes: cochlea, utricle, saccule and vestibule
16
Q
What embryologically is the ear made from?
What can embryology cause to a child?
A
It is made from the 1st and 2nd branch of the pharyngeal arch
Problems with big ears, absent outer ear or absence of the auricle

A
There is the outer ear:
External acoustic meatus and pinnacle
20
Q
Who does Glue ear affect ? What are RF: What cause it? What are 3 symptoms What are the mangement?
A
Anyone under the age of 12 but is increased in ages 2-5
Down’s Syndrome and Allergic Rhinitis
In children there are more narrow Eustachian tubes. This makes it harder to have a change in air and fluid pressure. This results in fluid being passed into nearby cells. Can lead to a vacuum forming and fluid to seep out of the middle ear.
Ear pain (ear tugging)
Deafness
Change in personality or decreased effort at school
Management: this includes:
- Watch and Wait
- Ballon treatment
- Grommets
- Hearing aids
21
Q
What are grommets and how do they work?
A
happens when you make a slit in the ear drum. Drain the fluid and add a grommet.
This allow air to get into the ear and improves hearing. Grommets eventually fall out after 6-12 months
This is why Glue ear doesn’t affect adults as the Eustachian tubes are wider
22
Q
What are the 4 main layers of the adrenal gland?
A
Outside to the inside:
- Zona Glomerulosa (aldosterone0
- Zona Fasiculata (cortisol)
- Zona Reticularis (androgens)
Medulla (adrenaline)
23
Q
How is cortisol released: mention all the stimulation and what it stimulates
A
Cortisol Releasing Hormone (CRH) is released from the hypothalamus
This then stimulates the anterior pituitary gland to release ACTH
ACTH then acts on the Zona Fasciulta in the adrenal gland and causes it to release cortisol
Cortisol stimulates androgen release from the Zona Reticularis
Adrenaline release from the medulla
24
Q
What does cortisol do? 3 things
A
Anti-inflammatory
Causes the breakdown of carbohydrates, lipids and proteins
Lead to a lowered immune response
25
What is released from the posterior pituitary gland?
vasopressin (ADH)
Oxytocin
26
What type of inheritance is congenital adrenal hyperplasia?
Why is it super important to get a diagnosis?
What population is more common in?
What pathophysiology does it cause?
A.R.
As it can cause an adrenal crisis and massive salt losing situation
Ashkenazi Jews
The idea that there is a 21-hydroxylase deficiency and this means that you get a high serum 17-hydroxuprogesterone
27
How does congenital adrenal hyperplasia present?
In females it is easy as it presents as ambiguous genitalia and enlarged clitoris
In males it is harder: may be penile enlargement and subtle hyperpigmentation.
They will later present after 7-14 days with vomiting, weight loss, lethargy and hyponatraemia and hyperkalaemia.
28
What will happen if congenital adrenal hyperplasia is not recognised?
You can get crisis in boys by 7-14 days after birth.
Nausea, Vomiting, dehydration, weight loss and lethargy,. Alongside hyponatraemia and hyperkalaemia.
By aged 2-4 you will get early virilisation
29
How do you diagnose congenital adrenal hyperplasia?
The condition is caused by 21 hydroxylase deficiency
This means that they patient will have a higher serum 17 hydroxuprogesterone level.
Look at pelvic US for organs
Bone Age
Karotyping
30
How do you treat congenital adrenal hyperplasia?

What is a febrile seizure?
When do they occur?
What triggers them?
What are the 3 types:
What investigations should you do?
```
What are some differentials:
A febrile seizure is a seizure caused by a viral illness and not by another infective or neoplasticism cause
They occur between the ages of 6 months and 5 yrs and have FH element
Triggers include: viral infections such as tonsillitis and otitis media.
The three types:
- Simple: less than 15 mins and no repeat in 24 hours
- Complex: focal symptoms and duration longer than 24 hours or recurrence in illness.
- Febrile status epileptoicus: longer than 30 mins
Investigations: U&E, FBC, LFT you need to do blood cultures and ESR and glucose. Need to do urine microscopy and LP in kids under 12 months
Post ictal fever, syncope and breath holding episodes are also possible causes
36
What is Gonadotrophin Deficiency classed as in girls and boys?
What diagnosis tests do you need to do:
In a Male: give a cause of primary and secondary hypogonadism?
Classed as 13 in girls and
14 in boys
In boys you need to look at LH, FSH, Testosterone, GnRH levels and karotyping
In females you need to do they same but look at oestrogen not testosterone.;
IN A MALE:
- Primary hypogonadism is caused by damage to Ledwig cells so loss in testosterone. Causes no sperm. But elevated LH and FSH
Cause: klienfelters
- Secondary hypogonadism: caused by problems in the pituitary gland. Meaning that low GnRH. Prader will I and Kallman syndromes are examples
37
What would the hormone profile in a Primary and Secondary Hypogonadism individual look like:
How do you treat
Primary:
- Will have high LH and FSH and normal testosterone
Secondary:
- low levels of LH and FSH and low testosterone
Give replacement oestrogen or testosterone
38
What are causes of Gonadotrophin deficiency in women?
Anorexia
Lots of sport
Radiation
Auto immune disease
39
What are the 4 types of leukaemia what is the most common in children?
ALL is the most common
Others include:
AML
CLL (seen mainly in elderly)
CML
40
What is leukaemia:
It is over-proliferation of the immature blast blood cells in the bone marrow.
These cells have no function and can fill up the bone marrow so there’s little space for the functioning cells
41
What is the pathophysiology of ALL leukaemia?
Who is it common in?
How does it present?
ALL affects the B and T lymphocytes. Meaning that it is a malignancy of the immature lymphoid cells.
Normally most derive from B cell precursors

You need to do a FBC and Blood Film
- Will have high WCC and blast cells visible
- Need to do a bone marrow biopsy and a CXR and LP.
44
How do you treat leukaemia?
You need to give blood and platelets
Probably will be neutropenia: so give prophylactic abs
To prevent tumour lysis syndrome give allopurinol.
Systemic Chemo and Spinal Chemo alongside a Bone marrow transplant

What is vesicureteric reflux?
This is a congenital abnormality at the vesicoureteric junction
Means the ureters are displaced laterally or just enter the bladder directly rather than at an angle.
