D. sucrase isomaltase def.
E. congenital chloride losing diarrhoea 

E. congenital chloride losing diarrhoea 

Congenital Chloride Diarrhoea

  • defect in Na+ independent Cl-/HCO3- exchanger within ileal and colonic epithelium – exchanger absorbs chloride from gastric acid and CFTR and secretes bicarb into lumen to neutralise acidity of gastric secretion
  • prenatal sign – dilated small bowel, can be mistaken for BO
  • severe life-threatening secretory diarrhoea during 1st weeks of life
  • lab findings – metabolic alkalosis, hypochloraemia, hypokalaemia, hyponatraemia (high plasma renin and aldosterone), fecal Cl- >90mmol/L and exceeeds fecal sodium and potassium
  • need lifelong KCL and NaCL substitution
  • long-term complications – urinary infections, hyperuricaemia with renal calcifications, renal insufficiency, HTN
  • febrile illnesses can exacerbate symtoms with severe dehydration and electrolyte imbalance
  • PPIs, cholestyramine and butyrate to reduce diarrhoea
  • Often symptoms regress with age

Sucrase isomaltase def

  • rare, AR disorder
  • complete absence of sucrase and reduced maltase digestive activity
  • sucrase isomaltase is found in brush border of the small intestine.  It catalyses breakdown of sucrose and starch/maltose to glucose and fructose
  • note that sucrose is a non-reducing sugar and maltose is a reducing sugar
  • symptoms – begin when exposed to sucrose of glucose polymer diet (eg non-lactose based formula, pureed food esp fruits)
  • diarrhoea, abdo pain, poor growth

Pyloric stenosis 

  • hypochloraemic, hypokalaemic metabolic alkalosis secondary to vomiting due to thickened pylorus.

Bartter (and Gitelman syndrome)

  • hypokalaemic metabolic alkalosis, hyperreninemia + polydipsia, polyuria

Child undergoes induction for ALL and found to have cerebral venous thrombosis. Which of the following chemotherapy agent is associated with CVT?

A. Aspariginase
B. Daunorubicin
C. Dexamethasone
D. Methotrexate
E. Vincristine 

A. Aspariginase

Drugs that enhance the risk of thrombosis include, most importantly, L-asparaginase and steroids.  There have also been reports of CVT with vincristine.

Asparaginase-induced deficiency of antithrombin III, the most important endogenous anticoagulant, significantly increases the risk of sinovenous thrombosis in the brain.  

It decreases protein synthesis, including synthesis of coagulation factors.  About 2% of children treated with L-asparaginase develop hemorrhagic or nonhemorrhagic infarcts consequent to CSVT. 

More common SE is anaphylaxis/allergic reaction and rarely pancreatitis.

Occurs in 15% of cases in TOF repair


A 3 day old infant is admitted to the Special Care Nursery with feeding difficulties. On examination there is severe hypotonia but no respiratory distress and deep tendon reflexes are preserved. There is no obvious facial weakness and no dysmorphism.

The most likely cause is:

A. Congenital myotonic dystrophy
B. Myotubular myopathy
C. Prader-Wili syndrome
D. Spinal Muscular Atrophy
E. Zellweger syndrome

C. Prader-Willi Syndrome

Congenital myotonic dystrophy and Myotubular myopathy would have facial weakness.

SMA would have reduced/absent reflexes

Zellweger – dysmorphism at birth

Prader willi dysmorphism is not obvious at birth and diagnosis often missed in earlier life. Hypotonic with feeding difficulties, no facial weakness and preserved DTR.


Stem talks about comparing criteria for major depressive disorder between child and adolescents with adults. Which criteria or symptom is more common or is present in child/youth/adolescent but not in adults?

E. poor concentration
F. feelings of worthlessness 

C. irritable mood.

Five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure.

Note:  Do note include symptoms that are clearly due to a general medical condition, or mood-incongruent delusions or hallucinations.

(1) depressed mood. Note: In children and adolescents, can be irritable mood.

(2) anhedonia
(3) Weight loss (or inadequate weight gain in children)
(4) insomnia or hypersomnia nearly every day

(5) psychomotor agitation or retardation nearly every day 
(6) fatigue or loss of energy nearly every day

(7) feelings of worthlessness or excessive or inappropriate guilt

Xray of a boy with a left-sided pneumothorax. Which of the following activities should be avoided for the next 6 months?

A. Playing the saxophone
B. Scuba diving
C. Snorkelling
D. Flying in an aeroplane
E. Flying in a helicopter 

B. Scuba Diving

From Up to Date

Commercial air travel in pressurized airplanes is not thought to precipitate recurrence of pneumothorax. However, because the consequences of a spontaneous recurrence occurring during air travel may be serious, guidelines for adults suggest avoidance of air travel until at least one week after full resolution of the pneumothorax. In addition, most authorities suggest avoidance of sports that involve extreme exertion and physical contact until the pneumothorax is fully resolved.

Activities such as deep sea diving or flying in small, unpressurized aircrafts are associated with increased risk of pneumothorax and should be avoided in individuals who did not undergo pleurodesis.


3 year old child with CP, longstanding history of GOR. Normal swallow on video fluoroscopy. On Omeprazole. Which is the following an indication for fundoplication?

A. Abnormal pH probe
B. Delayed gastric emptying on NM scan

Thiopurine methyltransferase (TPMT) level is useful for what chemotherapeutic agent to adjust dose and reduce toxicity prior to use?

A. Azathioprine
B. Cyclophosphamide
C. Cyclosporin
D. Methotrexate
E. Mycophenolate

A. Azathioprine

TPMT is an enzyme encoded by TPMT gene. TPMT is best known for its role in the metabolism of the thiopurine drugs such as azathioprine, 6-mercaptopurine and 6-thioguanine. TPMT catalyzes the S-methylation of thiopurine drugs.

Defects in the TPMT gene leads to decreased methylation and decreased inactivation of 6MP leading to enhanced bone marrow toxicity which may cause myelosuppression, anemia, bleeding tendency, leukopenia & infection.

10% of population have low activity so should be checked prior to tx

An 11 year old boy is rescued from a house fire. He has had 2 seizures. Saturations are 100% on face mask oxygen.

Blood gas is shown, demonstrating mild acidosis
CO2 27
CO Hb - 23

What is the most appropriate treatment for this child?
A. Heliox
C. Hyperbaric oxygen
D. Haemodialysis
E. Methylene blue

C. Hyperbaric Oxygen

HbCO levels often do not reflect the clinical picture, yet symptoms typically begin with headaches at levels around 10%. Levels of 50-70% may result in seizure, coma, and fatality.

Treatment of poisoning:

  • 100% oxygen OR
  • hyperbaric oxygen therapy,

Oxygen works as an antidote as it increases the removal of carbon monoxide from hemoglobin, in turn providing the body with normal levels of oxygen. Half-life of CO at room air temperature is 3-4 hours. One hundred percent oxygen reduces the half-life to 30-90 minutes; hyperbaric oxygen at 2.5 atm with 100% oxygen reduces it to 15-23 minutes.

Normal CO  levels are around 2% but can be upto 5% in smokers/living in industrialised areas

Methylene blue – used for methaemoglobulinaemia


A 4 year old girl has developed a rash on her hands 17 days after a living related HSCT for high risk ALL. The rash is itchy. It has not spread elsewhere on her body. Her liver function tests are normal.

Picture shown of non specific erythematous rash on palmar aspects of both hands, including fingers.
What is the most appropriate initial treatment?

A. Mycophenylate mofetil
B. Methotrexate
C. Topical steroid
D. Infliximab
E. Antithymocyte globulin

C. Topical Steroid

In most patients, the first (and most common) clinical manifestation of acute GVHD is a maculopapular rash, usually occurring at or near the time of the white blood cell engraftment. Topical steroids are the most commonly used skin-directed therapy for acute GVHD. Antihistamines may be used as adjuvant therapy for patients with pruritus.

Topical steroids differ in their strength, vehicle (eg, ointments, creams, lotions), and method of application. In general, for cutaneous GVHD, mid- to high-potency topical steroids are applied twice daily to moist skin and covered with warm wet towels as an occlusive measure ("wet wrap"). The choice of topical steroid and duration of therapy must take into account the location of disease.


A 6 hour-old infant is found to have a soft systolic murmur and tachypnea. Saturation measured from the right arm is 94% and the right leg 89%.

The finding is most consistent with which abnormality

A. Atrial septal defect
B. Interrupted aortic arch
C. Pulmonary stenosis
D. Transposition of the great vessels
E. Truncus arteriosis
F. Fallot’s tetralogy
G. Pulmonary atresia
H. Ebstein’s anomaly

(these potential answers are the combined listed from a few people)

B. Interrupted Aortic Arch

Interrupted aortic arch is characterized by interruption of the aortic arch distal to the left subclavian artery (Type A), proximal to the left subclavian artery (Type B), or between the innominate artery and the left common carotid artery (Type C).

Blood supply to arterial distributions proximal to the interruption is provided by the ascending aorta. Blood supply to arterial distributions distal to the interruption is provided by a patent ductus arteriosus. Arterial oxygen saturation proximal to the interruption is normal, while the arterial oxygen saturation distal to the interruption is lower than normal.

Closure of the patent ductus arteriosus in patients with interrupted aortic arch results in lower body hypoperfusion and acidosis. Infusion of prostaglandin E1 to maintain ductal patency is an important component of resuscitation and preoperative stabilization. Ventricular septal defect is a frequent association, especially with Types B and C. Surgical correction of this anomaly is performed during the neonatal period. 


2 year old child presents with a 6 months history of sleep disturbance. He would wake up suddenly, thrash around and cry. This happens before the parents go to bed. They would go to him immediately but he would be inconsolable. They would hold him and talk to him, and he would eventually settle and go to sleep. The duration is 5-20 minutes. The symptoms started 3 months ago when he started day care. They have been progressively getting worse, now occurring almost daily. He goes to bed at 830pm and gets up at 630am. There are no other sleep related symptoms.

He has no other medical history and he is well. There is no family history of sleep disorders, but his father walked in his sleep until the age of 12 years.

B. HbA1c
C. Compliance
D. Night hypoglycemia
E. Lipohypertrophy 

D. Night hypoglycemia

  • Glargine/lantus has long mechanism of action of 18-26hrs with a peakless profile.

A. Benztropine.

B. Cyproheptadine.

C. Diazepam.

D. Flumazenil.

E. Naloxone

A. Benztropine.

Benzatropine is an anticholinergic - antagonizes the effect of acetylcholine, decreasing the imbalance between the neurotransmitters acetylcholine and dopamine, which may improve the symptoms of early Parkinson's disease. 
Benzatropine is also a dopamine Reuptake inhibitor, which makes it useful for people with extrapyramidal symptoms who take antipsychotics.

A neonate presents to hospital with suspected Vit B12 deficiency. What drug should not be used for sedation?

A. Chloral hydrate
B. Ketamine
C. Midazolam
D. Nitrous oxide
E. Promethazine

D. Nitrous Oxide

Adverse effects that may be associated with nitrous oxide include gagging, coughing, hypotension, asthma attack, involuntary tracheal closure (spasm), lung damage, neuropathy, tinnitus, extremity numbness, anoxia and general respiratory distress, cardiac events (including myocardial infarcts), seizures, misperception of time, and vision-altering perceptions. Additional adverse effects include possible exacerbation of vitamin B12 deficiency, anemia, and decreased hematopoiesis.
Nitrous oxide has been shown to potentially inhibit methionine synthetase and cause an increase in homocysteine (Hcy) levels.

Vitamin B12 deficiency should be considered in the differential diagnosis of patients who present with psychiatric or neurological manifestations, especially in those with a clear history of nitrous oxide exposure. Pertinent laboratory testing should include B12, homocysteine, and methylmalonyl coenzyme A (CoA) levels. Although levels of B12 may be low to normal, levels of methylmalonyl CoA and homocysteine may be elevated.
Because of the potential delay in the appearance of clinical symptoms, the history of nitrous oxide exposure may be days to weeks prior to the presentation date. Intramuscular administration of cobalamin may be curative in these cases. Recovery may be slow even with high doses of vitamin B12.

No consistent guidelines on timing per Up to Date. 

The three most common treatments for Erb's Palsy are: Nerve transplants (usually from the opposite leg), Sub Scapularis releases and Latissimus Dorsi Tendon Transfers.

Nerve transplants are usually performed on babies under the age of 9 months since the fast development of younger babies increases the effectiveness of the procedure. Surgery is advocated at 3 months if there has been minimal recovery by this time. They are not usually carried out on patients older than 9/12 because when the procedure is done on older infants, more harm than good is done and can result in nerve damage in the area where the nerves were taken from. Scarring can vary from faint scars along the lines of the neck to full "T" shapes across the whole shoulder depending on the training of the surgeon and the nature of the transplant.

Subscapularis releases, however, are not time limited. Since it is merely cutting a "Z" shape into the subscapularis muscle to provide stretch within the arm, it can be carried out at almost any age and can be carried out repeatedly on the same arm; however, this will compromise the integrity of the muscle.

Latissimus Dorsi Tendon Transfers involve cutting the Latissimus Dorsi in half horizontally in order to 'pull' part of the muscle around and attach it to the outside of the biceps. This procedure provides external rotation with varying degrees of success. A side effect may be increased sensitivity of the part of the biceps where the muscle will now lie, since the Latissimus Dorsi has roughly twice the number of nerve endings per square inch of other muscles.

A 10 year old girl with congenital adrenal hyperplasia on hydrocortisone and fludrocortisone. BP 130/90. 17-OH progesterone level 4 (<4) and renin 2 (>4). What is the most appropriate next management:

a. Decrease fludrocortisone dose

b. Increase fludrocortisone dose

c. Decrease hydrocortisone dose

d. Increase hydrocortisone dose

e. Start an anti-hypertensive. 

a. Decrease fludrocortisone dose

?? Incorrectly remembered??

Hypertensive with LOW renin? Would expect high renin...

Fludrocortisone replaces the aldosterone that the adrenals should be making. Decreased aldosterone (fludrocortisone) caused dehydration, hyponatremia and hyperkalemia.

Aldosterone (fludrocortisone) stimulates Na+ retention. If Na+ is too low, this stimulates renin secretion to increase Na+. 

If renin is high = need to increase Fludro

If renin is low = need to decrease Fludro
