⚕️ FREE MSRA PODCAST – Attention Deficit Hyperactivity Disorder (ADHD)
🎧 A clear, high-yield breakdown of this common neurodevelopmental disorder in children – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• ADHD is a neurodevelopmental disorder marked by a persistent pattern of inattention, hyperactivity, and impulsivity, significantly interfering with functioning or development. Symptoms start before age 12 and persist in multiple settings.

📌 Causes & Risk Factors
• Strong genetic component (family history, twin studies)
• Environmental: prenatal exposure to smoking/alcohol, low birth weight, prematurity, brain injury
• Lead exposure, maternal mental health or substance misuse, social/environmental stress
• Associated with other neurodevelopmental and mental health conditions
• Mnemonic: “Genetics + Gestation + Growing up = ADHD risk”

📌 Pathophysiology
• Imbalance/dysregulation of neurotransmitters (mainly dopamine and norepinephrine)
• Altered brain network activity – particularly prefrontal cortex and basal ganglia
• Disrupted signalling leads to impaired executive function, self-control, and attention

📌 Symptoms
• Inattention: distractibility, disorganisation, forgetfulness, avoids effortful tasks
• Hyperactivity: fidgeting, inability to stay seated, excessive talking, “on the go”
• Impulsivity: blurting out answers, difficulty waiting, interrupting
• Mnemonic: “A HI FIVE” – Attention, Hyperactivity, Impulsivity, Forgetfulness, Incompletion, Verbal excess, Executive dysfunction

📌 Differential Diagnosis
• Anxiety or mood disorders (e.g. depression, bipolar)
• Autism spectrum disorder
• Oppositional defiant or conduct disorder
• Learning difficulties, intellectual disability
• Thyroid dysfunction, sleep disorders, substance misuse, Tourette’s, fetal alcohol syndrome

📌 Diagnosis
• Clinical assessment by a specialist (psychiatrist, paediatrician)
• DSM-5/ICD-10 criteria
• Input from parents/teachers (questionnaires like Conners, SDQ)
• Symptoms present in ≥2 settings, not better explained by another condition
• Assess for coexisting conditions

📌 Management
• Psychoeducation for family/school; address stigma and support strengths
• Behavioural interventions: parent training, school support, structure/routines
• Medication (for moderate/severe cases):
 – First line: methylphenidate
 – Others: lisdexamfetamine, atomoxetine
• Monitor growth, blood pressure, pulse; regular reviews and shared care
• Consider CBT for older children/adults
• NICE: Individualised, multi-modal approach; medication only when impairment is significant

📌 Complications
• Academic underachievement
• Social/relationship difficulties
• Low self-esteem
• Accidents/injuries
• Higher risk of anxiety, depression, substance misuse, legal problems if untreated

📌 Prognosis
• Many improve with time and appropriate support, but symptoms often persist into adulthood
• Early intervention and holistic care improve outcomes
• Prognosis worsens with comorbidities or lack of support

⚕️ FREE MSRA PODCAST – Acute Asthma in Children
🎧 A clear, high-yield breakdown of this paediatric respiratory emergency – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Acute asthma in children is a sudden worsening of asthma symptoms (wheeze, breathlessness, chest tightness, cough) due to airway inflammation and narrowing.

📌 Causes & Risk Factors
• Viral respiratory infections (most common)
• Allergens (pollen, dust mites, pet dander)
• Cold air, exercise
• Air pollution, cigarette smoke
• Emotional stress
• Family history of asthma/allergy, previous attacks
• Mnemonic: “VACCINE” – Viral, Allergens, Cold air, Cigarette smoke, Irritants, Noted history, Exercise

📌 Pathophysiology
• Airway inflammation, bronchial hyperreactivity, and increased mucus
• Bronchoconstriction narrows the airways, reduces airflow
• Chronic sensitivity + acute trigger = sudden symptoms

📌 Symptoms
• Expiratory wheeze, breathlessness, tachypnoea
• Cough (often nocturnal), chest tightness
• Use of accessory muscles, nasal flaring, retractions
• Difficulty speaking/feeding (sign of severity)
• Mnemonic: “WHEEZE” – Wheeze, Hard breathing, Exhaustion, Exercise-triggered, Zero air, Eating/feeding difficulties

📌 Differential Diagnosis
• Bronchiolitis
• Pneumonia
• Foreign body aspiration
• Cystic fibrosis
• Vocal cord dysfunction
• ITP, allergy, GORD (rarely in exam)

📌 Diagnosis
• Clinical assessment (history & exam)
• Oxygen saturation (SpO2)
• Peak expiratory flow rate (PEFR, if age >5)
• Consider chest X-ray only if complications/doubt
• ABGs if life-threatening
• Tip: “If you hear a wheeze, always check SpO2!”

📌 Management
• Immediate: Inhaled salbutamol (via spacer/nebuliser)
• Oxygen if SpO2 <94% (aim for 94–98%)
• Oral/IV corticosteroids (prednisolone or hydrocortisone)
• Add nebulised ipratropium for severe attacks
• IV magnesium sulphate/aminophylline if poor response
• Admit if severe/life-threatening or poor response
• Long-term: Inhaled corticosteroids, asthma action plan, trigger avoidance, GP/specialist follow-up
• NICE/UK priorities: Follow paediatric asthma pathways, rapid escalation if life-threatening

📌 Complications
• Respiratory failure, hypoxia
• Pneumothorax, atelectasis
• Hospital/ICU admission
• Poor growth, missed school, psychological impact

📌 Prognosis
• Excellent with prompt treatment and ongoing control
• Many children improve with age, but some have persistent symptoms into adulthood

⚕️ FREE MSRA PODCAST – Aplastic Anaemia
🎧 A clear, high-yield breakdown of this rare bone marrow failure syndrome – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Aplastic anaemia is a rare, life-threatening condition where the bone marrow fails to produce enough blood cells, leading to pancytopenia (↓ red cells, white cells, and platelets).

📌 Causes & Risk Factors
• Autoimmune destruction of bone marrow stem cells
• Viral infections – e.g. hepatitis, EBV, HIV, parvovirus B19
• Drugs – chloramphenicol, sulfonamides, chemotherapy
• Toxins – benzene, radiation
• Inherited syndromes – e.g. Fanconi anaemia
• Pregnancy (rare)
💡 Mnemonic: “A-VIT D RIP” – Autoimmune, Viruses, Inherited, Toxins, Drugs, Radiation, Idiopathic, Pregnancy

📌 Pathophysiology
• Damage or loss of hematopoietic stem cells in the bone marrow
• ↓ Production of all three blood cell lines
• Result: anaemia → fatigue, neutropenia → infections, thrombocytopenia → bleeding

📌 Symptoms
• Fatigue, pallor, SOB
• Frequent/severe infections
• Easy bruising, petechiae, nosebleeds, gum bleeding
• In children: purpura, prolonged illness, growth delay
💡 Tip: No lymphadenopathy or hepatosplenomegaly usually – think other causes if present

📌 Differential Diagnosis
• Myelodysplastic syndromes (MDS)
• Paroxysmal nocturnal haemoglobinuria (PNH)
• Hypocellular AML
• Hypersplenism
• Severe infections, TB
• Nutritional deficiencies (B12/folate)
• Autoimmune diseases (e.g. SLE)
• Hairy cell leukaemia, lymphoma

📌 Diagnosis
• FBC: Pancytopenia
• Bone marrow biopsy: Hypocellular/aplastic marrow
• Reticulocyte count: ↓
• Flow cytometry: PNH clone
• Viral screen: EBV, HIV, hepatitis
• Genetic testing: Fanconi anaemia (esp. <35y)
• Imaging: CXR, abdo USS (rule out hepatosplenomegaly)
💡 Mnemonic: “Biopsy CONFIRMS, Bloods SCREEN”

📌 Management
• Supportive:
– RBC/platelet transfusions
– Iron chelation (if transfusion-dependent)
– Irradiated blood products
• Immunosuppression:
– ATG + cyclosporine (first line in most)
– Add eltrombopag to stimulate marrow
• Infection prevention:
– Prophylactic antibiotics/antifungals/antivirals
• Curative:
– Haematopoietic stem cell transplant (esp. <40y with matched sibling)
💡 NICE: Monitor closely and report drug causes via Yellow Card Scheme – https://yellowcard.mhra.gov.uk/

📌 Complications
• Life-threatening infections and bleeding
• Evolution into MDS, AML, or PNH
• Graft failure, GVHD (if transplanted)
• Iron overload with multiple transfusions
• Long-term immunosuppression side effects

📌 Prognosis
• Variable depending on severity and response
• Severe untreated: high mortality within 1–2 years

⚕️ FREE MSRA PODCAST – Apgar Score
🎧 A clear, high-yield breakdown of this essential newborn assessment tool – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• The Apgar score is a rapid clinical assessment done at 1 and 5 minutes after birth, evaluating a newborn’s immediate health based on five signs: Appearance (skin colour), Pulse (heart rate), Grimace (reflex response), Activity (muscle tone), and Respiration (breathing effort).

📌 Causes & Risk Factors
• Low scores can be caused by prematurity, birth asphyxia, maternal medication, infection, difficult delivery, or congenital abnormalities.
• Mnemonic: APGAR = Appearance, Pulse, Grimace, Activity, Respiration.

📌 Pathophysiology
• Assesses how well the newborn has adapted from intrauterine to extrauterine life by checking vital organ function and neurological response immediately after birth.

📌 Symptoms
• Normal score (7–10): Vigorous crying, pink colour, good muscle tone.
• Low/moderate score (0–6): Weak/absent cry, blue or pale, floppy, poor response to stimulation, bradycardia, or apnoea.

📌 Differential Diagnosis
• Prematurity
• Birth asphyxia
• Respiratory distress syndrome
• Sepsis
• Neurological disorders

📌 Diagnosis
• APGAR scoring at 1 and 5 minutes (sometimes repeated at 10 minutes):
 – Each component (0–2 points), total score 0–10
 – 7–10: Normal
 – 4–6: Moderate distress (may need support)
 – 0–3: Severe distress (needs immediate resuscitation)
• Mnemonic tip: “A PGAR Newborn Review”

📌 Management
• Score 7–10: Routine postnatal care
• Score 4–6: Provide supportive measures (stimulation, oxygen, monitor closely)
• Score 0–3: Immediate resuscitation (airway, breathing, circulation)
• Reassess at 5 and 10 minutes if low

📌 Complications
• Hypoxic-ischaemic encephalopathy
• Long-term developmental delay (if hypoxia not corrected)
• Risk of neonatal death (with persistently low scores)

📌 Prognosis
• Most babies with a normal Apgar score have excellent outcomes
• Low initial scores that rapidly improve generally have good prognosis
• Persistent low scores can indicate increased risk of morbidity and long-term complications

⚕️FREE MSRA PODCAST –Aortic Stenosis

🎧 A clear, high-yield breakdown of this critical paediatric heart valvecondition – perfect for exam prep andreal-life clinical scenarios.

🧠Key Learning Points

📌Definition

• Aortic stenosis(AS) is the narrowing of the aortic valve opening, restricting blood flow fromthe left ventricle to the aorta. In children, it’s usually congenital, but itcan also be acquired.

📌Causes & RiskFactors

• Congenital bicuspid aortic valve (most commonin children – valve with two leaflets instead of three)

• Other congenitalmalformations: unicuspid valve, supravalvular AS (e.g. Williams syndrome)

• Age-related calcification (main cause inadults)

• Post-inflammatory (e.g. rheumatic fever)

• Family history, hypertension, chronic kidneydisease

• Mnemonic: WATT – Williams,Aortic coarctation, Turner syndrome, and bicuspid valve

• Mnemonic for general risk: Ages & Associations:Age, Anomalies (congenital), Genetics, Elevated arterial pressure(hypertension), Syndromes

📌Pathophysiology

• Narrowed valveincreases resistance → left ventricle must work harder

• Left ventricular hypertrophy develops as themuscle thickens to compensate

• If uncorrected,eventually leads to heart failure as the muscle stiffens and function declines

📌Symptoms

• May be asymptomatic (mild/moderate AS in children)

• Classic triad (Mnemonic: SAD):

 – Syncope (fainting)

 – Angina (chest pain)

 – Dyspnoea (shortness of breath)

• Others: Fatigue,palpitations, heart failure signs (swollen legs, poor feeding in infants,tachypnoea, hepatomegaly)

• Severe in neonates/infants: Cyanosis, weakpulses, heart failure

📌DifferentialDiagnosis

• Innocent/flowmurmurs (esp. in children)

• Aortic sclerosis

• Aorticregurgitation

• Infectiveendocarditis

• Aortic rootdilation

• Pulmonary valvestenosis

• Septal defects(ASD/VSD)

📌Diagnosis

• Echocardiography (gold standard: assessesvalve, severity, LV function)

• ECG: May show LV hypertrophy

• CXR: May show enlarged heart, calcification

• Others: BNP, exercise testing, CT/MRI(occasionally), cardiac catheterisation if unclear

• Severity (Echo gradients):

 – Mild: Mean <25 mmHg

 – Moderate: 25–40 mmHg

 – Severe: >40 mmHg

📌Management

• All paediatric cases: Refer to paediatriccardiology

• Mild: Regular follow-up, observation

• Moderate/severe: Balloon valvuloplasty(children), surgical repair/replacement (esp. with symptoms or severe gradient)

• Adults: SAVR (surgical) or TAVI(transcatheter), depending on risk/profile

• Treat heart failure or arrhythmias as needed

• No medical cure; medications are forsymptom/support only

• NICE: Symptomatic severe AS = urgentintervention; consider for asymptomatic severe AS with LV dysfunction orabnormal exercise test

📌Complications

• Heart failure

• Arrhythmias (e.g.AF)

• Infective endocarditis

• Stroke/embolism

• Sudden cardiacdeath (rare in asymptomatic, higher in severe/symptomatic)

📌Prognosis

• Variable; worsewith symptoms, severe gradient, or LV dysfunction

• Without intervention: Poor survival in severesymptomatic cases (5-year survival as low as 15–50%)

• With valve replacement: Survival and quality oflife greatly improved

🧠 Key Learning Points

📌 Definition
• Acute Lymphoblastic Leukaemia (ALL) is a rapidly progressing cancer of lymphoid progenitor cells, leading to overproduction of immature lymphoblasts in bone marrow and blood.

📌 Causes & Risk Factors
• Usually a mix of genetic mutations (chromosomal translocations, e.g. t(12;21), Philadelphia chromosome) and environmental factors
• Risk increased with Down syndrome, certain inherited syndromes, prior radiation, family history
• Most common in children aged 2–5 years
• Mnemonic: “DNA-RISK” – Down syndrome, No clear cause, Acquired gene changes, Radiation, Inherited syndromes, Secondary to prior cancer therapy, Kids

📌 Pathophysiology
• Uncontrolled proliferation of lymphoblasts
• Marrow failure (crowding out healthy blood cells)
• Infiltration of organs (liver, spleen, CNS, lymph nodes)

📌 Symptoms

• Immunophenotyping: B vs T cell
• Cytogenetics: guides prognosis (e.g. t(9;22), t(12;21))
• CXR (mediastinal mass), lumbar puncture for CNS disease
• Memory tip: “Blasts = BAD” (Blasts on Blood film = ALL until proven otherwise)

📌 Management
• Multi-phase chemotherapy: induction, consolidation, maintenance
• CNS prophylaxis: intrathecal chemo ± cranial radiotherapy
• Supportive care: transfusions, infection prevention
• High-risk/relapse: stem cell transplant, CAR-T therapy (esp. B-cell ALL)
• UK focus: Follow local paediatric haematology/NICE guidelines

📌 Complications
• Infections, bleeding, tumour lysis syndrome
• Organ damage (heart, liver), infertility
• Long-term: growth/learning issues, secondary cancers, relapse

📌 Prognosis
• Cure rates ~80–90% in children; lower in adults

👶🦻 Deep Dive: Acute Otitis Media – Paediatrics for the MSRA
🎧 It’s the middle of the night, your child’s crying with ear pain – could it be AOM? In this episode, we cover everything you need to know about acute otitis media, one of the most common childhood infections.

📌 What is AOM?
• 🎯 Acute inflammation of the middle ear
• Often follows a cold or URTI
• Related conditions: glue ear (OME), CSOM, cholesteatoma, mastoiditis
• In ~5% of cases, the eardrum may perforate

🦠 Causative Organisms
🔬 Bacterial:
• Strep pneumoniae (pneumococcus)
• Haemophilus influenzae (non-flu)
• Moraxella catarrhalis
🦠 Viral:
• RSV, influenza, rhinovirus
• SARS-CoV-2 detected in post-mortem studies!

⚠️ Risk Factors
🧒 Young age (esp. <2 yrs)
🚬 Passive smoking
🏫 Daycare attendance
🍼 Formula feeding
🧬 Craniofacial abnormalities (e.g., Down syndrome, cleft palate)
📆 Winter season
🎯 First AOM at a young age = higher risk of recurrence

🔬 Pathophysiology
• 🎯 Blocked eustachian tube = fluid builds up behind tympanic membrane
• Bacteria/viruses multiply = inflammation & pressure
• Kids have shorter, more horizontal tubes = easier for bugs to spread from URTIs

🧠 Differentials
• OME (glue ear – fluid, but no infection)
• Otitis externa (swimmer’s ear)
• Referred pain (dental/TMJ)
• Cholesteatoma
• Bullous myringitis
• Foreign bodies
• CSOM

📊 Epidemiology
📈 >2/3 of children will have AOM by age 3
🎯 Peak incidence: 6–15 months
🌍 ~700 million cases/year globally (🧒 Half in kids <5)
🏥 33 deaths per 10 million (mostly in infants <1 in low-income countries)

🩺 Clinical Features
👶 Ear pain (otalgia)
🥵 Fever
😢 Irritability, poor feeding, disturbed sleep
🔊 Hearing loss
💧 Ear discharge if perforation occurs
👀 On exam: bulging, red, opaque eardrum, +/- fluid level or perforation

🧪 Investigations
✅ Diagnosis is clinical
🧫 Ear swab: only if discharge, grommets, or recurrent infections
🎧 Hearing test: if long-term hearing loss suspected
🧠 CT/MRI: if complications suspected (rare)

💊 Management
🩹 First line: Pain relief (paracetamol/ibuprofen)
⏱️ Consider delayed antibiotics for 48–72 hrs if mild
💊 Antibiotics:
• 1st line: Amoxicillin (5 days)
• Allergy: alternatives or co-amoxiclav if worsening
🚫 Antihistamines, decongestants & echinacea = not effective

🏥 When to Refer
📉 No improvement/worsening after a few days
👂 Recurrent AOM (ENT referral)
🎧 Hearing loss or complications
🧪 Grommets or specialist management for chronic issues
🧷 Tympanocentesis in select severe cases

📈 Prognosis
✅ Excellent – most recover in 7–10 days
⚠️ Some may develop CSOM or hearing issues
🧠 Serious complications (rare): mastoiditis, meningitis, facial nerve palsy, intracranial abscesses, sepsis

🛡️ Prevention Tips
🚭 Avoid passive smoking
🍼 Avoid supine feeding
🧸 Limit dummy use after 6–12 months
💉 Keep vaccinations up to date (e.g., pneumococcal vaccine)
👨‍⚕️ ENT input for frequent or complex AOM

⚕️ FREE MSRA PODCAST – Chronic Myeloid Leukaemia (CML)
🎧 A clear, high-yield breakdown of this blood cancer involving the Philadelphia chromosome – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• CML is a chronic myeloproliferative neoplasm characterised by uncontrolled proliferation of myeloid cells in the bone marrow, due to the Philadelphia chromosome.

📌 Causes & Risk Factors
• Caused by a specific translocation t(9;22) forming the BCR-ABL fusion gene
• Risk increases with:
– Age (typically diagnosed at median age 72)
– Male gender
– Prior radiation exposure (e.g., atomic bomb survivors)
– Previous chemotherapy or radiotherapy
– Smoking
– Rare genetic predispositions
💡 Mnemonic: AGGRIP – Age, Gender, Genetics, Radiation, Iatrogenic, Pollutants/Smoking

📌 Pathophysiology
• t(9;22) → BCR-ABL fusion gene → constitutively active tyrosine kinase
• Causes uncontrolled proliferation of granulocytes (esp. neutrophils, eosinophils, basophils)
• Accumulation of immature cells crowds out normal marrow function

📌 Symptoms
• Often asymptomatic in chronic phase
• If symptomatic:
– Fatigue
– Night sweats
– Weight loss
– Splenomegaly (early satiety, LUQ pain)
– Anemia-related symptoms
– Easy bruising
– Gout (↑ urate from cell turnover)
💡 Mnemonic: F.N.W.S.A.G. – Fatigue, Night sweats, Weight loss, Splenomegaly, Anemia, Gout

📌 Differential Diagnosis
• Other myeloproliferative neoplasms (PV, ET, MF)
• Leukemoid reaction
• Acute leukemias

📌 Diagnosis
• FBC: ↑ WCC, left shift, basophilia
• Blood film: spectrum of granulocytes
• Bone marrow biopsy
• Cytogenetics: Philadelphia chromosome (t(9;22))
• Molecular: BCR-ABL via PCR/FISH
💡 Tip: Blood film resembling marrow sample is a CML clue

📌 Management
• First-line: Tyrosine kinase inhibitors (TKIs), e.g. imatinib
• Alternatives: dasatinib, nilotinib for resistance/intolerance
• Monitor via:
– Hematologic remission (blood counts)
– Cytogenetic remission (Ph+ cells)
– Molecular remission (BCR-ABL levels)
• Stem cell transplant (allo-HSCT) for refractory cases
💡 NICE: Imatinib usually first-line in chronic phase
https://www.nice.org.uk/guidance/ta251

📌 Complications
• Blast crisis (progression to acute leukaemia)
• Resistance to TKIs
• Organ damage from hyperviscosity
• Side effects from long-term therapy

📌 Prognosis
• Excellent with treatment:
– 5-year survival >90%
– 10-year survival ~84%
– Many achieve deep molecular remission
• Worse prognosis if blast phase or resistant mutations

🎙️ Deep Dive: Acute Myeloid Leukaemia (AML) – The Bone Marrow Breakdown
🔬 Your ultimate MSRA revision guide to one of the most exam-relevant haematological malignancies.

🧬 What is AML?
• Cancer of the bone marrow involving the myeloid cell line
• Characterised by >20% blasts and blocked cell differentiation
• Most common acute leukaemia in adults

⚠️ Why It Matters for MSRA
• High-yield due to varied symptoms and diagnostic complexity
• Strong emphasis on genetic classification and risk stratification
• Management includes chemo, targeted therapy, transplant, and supportive care

🔥 Causes & Risk Factors
• Genetic mutations or inherited syndromes (Down’s, Fanconi, Bloom)
• Previous chemotherapy/radiotherapy (therapy-related AML)
• Benzene exposure, atomic radiation
• Progression from MDS, CML, or aplastic anaemia

🩺 Classic Clinical Presentation
• Fatigue, pallor (anaemia)
• Infections (neutropenia)
• Bleeding/bruising (thrombocytopenia)
• Bone pain, hepatosplenomegaly, gingival hypertrophy
• Leukostasis: respiratory distress, confusion if WCC >100×10⁹/L
• Rare: skin lesions (leukaemia cutis), DIC

🔍 Differential Diagnosis
• ALL, MDS, aplastic anaemia
• HLH, lupus, vitamin deficiencies
• Drug-induced cytopenia
• Other marrow-infiltrating malignancies

🧪 Diagnosis Essentials
• FBC: pancytopenia or ↑ WCC
• Bone marrow biopsy: >20% blasts = AML
• Flow cytometry confirms lineage
• Cytogenetics: translocations, deletions
• Molecular markers: FLT3, NPM1, CEBPA
• Clotting, urate, LDH, HLA typing if transplant planned

💊 Treatment Pathway

1. Induction chemotherapy: e.g. 7+3 regimen (cytarabine + anthracycline)

2. Consolidation: high-dose chemo or stem cell transplant

3. Maintenance: e.g. oral azacitidine (in selected patients)

4. APL subtype: ATRA + arsenic trioxide = targeted cure!

5. Supportive care: transfusions, antimicrobials, tumour lysis prevention

📊 Prognosis & Outcomes
• Median age at dx ≈ 67 yrs; survival best in <60s
• Cytogenetics/molecular mutations = key predictors
• Better prognosis with NPM1+ / FLT3−, worse with TP53, therapy-related AML
• Paediatrics: 65–75% 5-year survival; adults more variable
• Secondary AML or TAML = poorer outcomes
