A

transient aplastic crisis in those with sickle cell/thalassaemia/hereditary spherocytosis/iron deficiency anaemia
can cause immunocytopenia in immunodeficient patients
can cause meningoencephalitis in immunocompromised
DANGEROUS IN PREGNANCY

328
Q

what are the features of osteosarcoma

A

= bone cancer
10-20 y/o
most commonly femur (tibia/humerus)
** persistent bone pain, especially at night **
bone swelling/palpable mass/RoM

329
Q

describe the diagnosis of osteosarcoma

A

very urgent direct access XR in 48 hours if unexplained bone pain/swelling
if XR suggest osteosarcome - urgent specialist assessment 48hrs
blood test = raised ALP
CT
MRI
bone scan
PET scan
bone biopsy

330
Q

describe the features of osteosarcoma on XR

A

poorly defined lesions in bone
destruction of normal bone
fluffy appearance
periosteal reaction = sunburst appearance

331
Q

how is osteosarcoma managed

A

surgical resection of lesion with limb amputation
adjuvant chemo
MDT team
main complication = pathological bone fractures and metastasis

332
Q

what is a wilm’s tumour and how does it present

A

= nephroblastoma = cancer of kidneys
presents 0-5 y/o
asymptomatic abdo mass
adbo pain
haematuria
UTI
HTN

333
Q

how is wilm’s tumour diagnosed and managed

A

FBC
renal function
electrolytes
urinalysis
USS show distortion of renal pelvis
renal angiography
CT/MRI for staging
Tx = nephrectomy followed by chemo
routine postop radiotherapy is stage 3
prognosis = 90% survive long term
increased risk of second tumours in wilms survivors

334
Q

what is a rhabdomyosarcoma

A

malignancy of connective tissue where abnormal cells arise from primitive muscle cells
most common around head/neck
bladder (20%)
muscles/limbs/chest (15-20%)
= highly malignant and grow rapidly
87% patients are <15 (rarely affect adults)

335
Q

what are the risk factors of rhabdomyosarcoma

A

neurofribromatosis
fetal alcohol syndrome
parental use of marijuana/cocaine
exposure to XR

336
Q

how does rhabdomyosarcoma present

A

expanding lump/swelling = may be painful
nose - nasal obstruction/discharge
eyes = swelling eyeball
adbdomen = pain/change in bowel habit
bladder = haematuria

337
Q

how is rhabdomyosarcoma diagnosed

A

non resolving lumps in children = investigated for cancer
bloods = anaemia/raised ALT
urinalysis = haematuria
XR/CT/MRI
bone scan look for mets

338
Q

how is rhabdomyosarcoma managed

A

surgery for all lesions if possible
chemo (vincristine/cyclophosphamide etc)
post-op radiotherapy
prognosis = 60% children/teens cured

339
Q

describe retinoblastoma

A

embryonal tumour of retina = most common eye malignancy in children
inutero-5 y/o onset
40% = hereditary (AD)

340
Q

how does retinoblastoma present and what are the key differentials

A

abnormal pupil (leukocoria)
strabismus
deterioration of vision
red/irritated eye
Ddx:
cataracts
hamartomas
choroiditis

341
Q

how is retinoblastoma diagnosed and managed

A

any child showing indication = red reflex performed
exam under anaesthesia
bidimensional ocular USS/MRI
evaluate presence of mets
genetic counselling
Mx: urgent opthamology referral
1. surgery
2. chemo
3. radiation
99% survival in UK
invasion of optic nerve most significant prognostic factor

342
Q

what are the most common types of brain cancer in children

A

astrocytoma most common = most are low grade, slow spread
medullablastoma = most common high grade, fast spreading
