How does SVT in children differ from physiologic

sinus tachycardia? SVT typically has the following features:

Sudden onset and termination rather than a gradual change in rate

Persistent ventricular rate of >180 bpm Fixed or almost fixed RR interval on ECG Abnormal P-wave shape or axis or absent P

waves Little change in heart rate with activity, crying,

or breath holding

symptoms?2. What is the preferred method of

gastrointestinal decontamination in patients with iron overdose?

3. What is the antidote with dose?4. What metal intoxication can mimic

Kawasaki disease?

Answers1. Stage 2 (6-24 hours): Iron silently

accumulates in the mitochondria during this period, which is relatively free of symptoms.

2. Whole-bowel irrigation-Syrup of ipecac is no longer recommended, and activated charcoal will not adsorb iron. Many adult-strength iron-containing

pills are very large and are often too large for orogastric lavage 3. Deferoxamine

Iron Toxicity StagesStage 1 (0.5-6 hours): During this stage, iron exhibits

a direct corrosive effect on the small bowel. Symptoms include nausea, vomiting, abdominal pain, and/or gastrointestinal hemorrhage.

Stage 2 (6-24 hours): Iron silently accumulates in the mitochondria during this period, which is relatively free of symptoms.

Stage 3 (4-40 hours): This phase is characterized by systemic toxicity with shock, metabolic acidosis, depressed cardiac function, and hepatic necrosis.

Stage 4 (2-8 weeks): During this phase, pyloric stenosis and obstruction can develop as a result of earlier local bowel irritation.

with Schwartz formula?2. What is Stage II Chronic Kidney disease (CKD) in

terms of GFR?3. State True/ False

a. Growth hormone is a mode of treatment for short stature due to CKD.

b. Anemia in CKD is caused primarily due to loss of ferritin in urine.

c. The most common form of renal osteodystrophy seen with CKD is high turnover bone disease.

Answers1. GFR(ml/min/1.73m2)

= k x Height (cm) serum creatinine (mg/dL)where k is

0.33 for low-birthweight infants younger than 1 yr,

0.45 for term AGA infants younger than 1 yr, 0.55 for children and adolescent females and 0.70 for adolescent males
