Criteria of Pathological Jaundice:

Jaundice is pathologic if:

1-It is evident in the first day of life, also at any time.

2-Bilirubin increases more than 0.5mg/dl/hr or 5mg/dl/day.

3-Peak bilirubin is greater than 13mg/dl in trerm or 15mg/dl in preterm infant.

4-Direct bilirubin fraction is greater than 1.5-2 mg/dl.

5-Associated problems (e.g. anemia, hepatosplenomegaly, signs of sepsis, kernicterus).

6-Clinical jaundice persisting for more than 1week in a full term infant or 2 weeks in a preterm infant.

#Pediatrics
Some equations to ease calculation:

Child’s weight at 3–12 months = (age in months + 8)/2

Child’s weight at 1–6 years = 2(age in years) + 8

In children aged 2–12 years, height can also be estimated by using the following formula:
-Child’s height in centimeters = 6.5(age in years) + 75

#Infections
Complications of exchange transfusion:
1- Apnea and bradycardia, thrombocytopenia, hypervolemia due to overload may lead to cardiac failure.
2-Hypothermia due to exposure especially during winter months.
3-Incompatible blood transfusion reactions.
4-Vomiting and aspiration if stomach isn't empty.
5-Cardiac arrhythmias or arrest.
6-Hypocalcemia.
7-Infections,e.g. sepsis, hepatitis, etc.
8-Air embolism.
9-Hypoglycemia.
10-Metabolic acidosis,vascular spasm.


#Pediatrics
Clinical manifestations of Sickle cell anemia:

1-It is common in negros.

2-Starting after the 6th month of age. Because in this asymptomatic period high levels of HbF protect the patient.

3-Features of anemia"Non- specific":
-Fatigue, Headache, Poor feeding, Lethargy, Dizziness, Dyspnea, irritability, Arthralgias, abdominal pain.
Also signs such pallor, Jaundice, tachycardia and postural Hypotension.

4-Features of chronic hemolysis such as hepatospleenomegaly, GB stones, skeletal manifestations.

5-Renal disorders (CRF, NS, Proteinuria.).

6-Crisises such as splenic sequestration crisis, aplastic crisis, vaso-occlusive episodes such as stroke, pulmonary infarction hepatopathy or hematuria, acute chest syndrome.
May be the presenting features.
PP of crisis: hypoxia, dehydration, infection, stress, trauma..etc.

7-Increase susceptibility to overwhelming infection especially S.pneumoniae.

8-Late manifestations:
1-Long term consequences of chronic hemolytic anemia.
2-Tissue hemosiderosis.
3-Gallstones.
4-Leg ulcers.
5-Renal disease.


#Pediatrics
Why do newborns develop
physiological jaundice?


1-Decreased RBC life span.
2-Decreased Y protein and Ligandin in liver.
3-Decreased activity of UDP glucronyl transferase.
4-Increased enterohepatic circulation.

-Minimal change nephrotic syndrome (MCNS) is most commonly seen in 85% of all cases of nephrotic syndrome in children.

#Pediatrics
Nephritic syndrome vs Nephrotic syndrome.

Note

•Adult remnants of fetal circulation includes:

1- Umbilical vein = Ligamentum teres
2- Ductus venosus = Ligamentum venosus
3- Foramen Ovale = Fossa cialis
4- Umbilical arteries = Proximal part contribute to the internal iliac arteries and superior vesical arteries whereas the distal parts collapse and become fibrotic forming the medial umbilical ligaments.
5- Ductus arteriosus= Ligamentum arteriosum or Harvey's ligament.

Remember:

-The term malnutrition is used to denote undernutrition, overnutrition and selective nutritional deficiencies.

However, the terms malnutrition, PEM and undernutrition are often used interchangeably.

-Undernutrition occurs due to inadequate intake, poor absorption or excessive loss of nutrients.

-Overnutrition occurs due to excessive intake of nutrients.

#Pediatrics
Obesity is a condition with exceas amount of body fat.
-There is an increase in the number and size of adipocytes.

-A child whose weight for age is between 110% and 120% of the standard weight is known as overweight.

-While that more than 120% of the
standard weight is obese.

#Pediatrics
Remember:

-PDD "Postdiarrheal abdominal distension"
It occurs as a complication after diarrhea due to hypokalemia, paralytic ilius.


#Pediatrics
Subacute sclerosing panencephalitis:

-It is a rare form of chronic progressive brain inflammation caused by slow infection with certain defective strains of hypermutated measles virus.

-Cause: Measles virus.

-Usual onset: 6-20 years after infection with measles.
-Frequency: About 1 in 10,000 people infected by measles.
-Symptoms: Behavior changes, seizures, spasticity, poor coordination,ataxia, coma.
-It's also divided into 4 stages
-Diagnostic: EEG, Serologic testing, brain biopsy.
-Prevention:
Measles vaccine
-Treatment:
Supportive treatment,
Intrathecal interferon alpha, intravenous ribavirin.
-Prognosis: usually fatal.

It is not a specific sign of infected endocarditis
