Q

Child with vomiting and diarrhea. On exam .. Sunken eyes.. Skin turgor.. Depressed fontanelle.. The degree of dehydration is

A. 5%

B. 10%

C. 15%

D. 20%

A

Answer: b

Degree of dehydration for uptodate:

mild dehydration (3 to 5 percent volume loss) – a history of fluid losses may be the sole finding, as clinical signs may be absent or minimal.

moderate dehydration (6 to 10 percent volume loss) – signs and symptoms are now apparent and can include the following: tachycardia, orthostatic falls in blood pressure, decreased skin turgor, dry mucous membranes, irritability, decreased peripheral perfusion with a delay in capillary refill between two and three seconds, and deep respirations with or without an increase in respiratory rate. There may be a history of reduction in urine output and decreased tearing, and, in infants, an open fontanelle will be sunken on physical examination.

severe dehydration (>10 percent volume loss) – such children typically have a near-shock presentation as manifested by hypotension, decreased peripheral perfusion with a capillary refill of greater than three seconds, cool and mottled extremities, lethargy, and deep respirations with an increase in rate. Severe hypovolemia requires immediate aggressive isotonic fluid resuscitation to restore the effective circulating volume (ecv) and prevent ischemic tissue injury.

Q

child with flat buttocks. What investigation will you do (celiac)?

A. Antibody

B.Intestine biopsy

A

Answer: A

Antibody testing, especially IgA anti-tissue transglutaminase antibody (IgA TTG), is the best first test, although biopsies are needed for confirmation

; in children younger than 2 years, the IgA TTG test should be combined with testing for IgG-deamidated gliadin peptides.

Celiac disease : gluten sensitive enteropathy

Classical presentation is at 8–24 months with abnormal stools, failure to thrive, abdominal distension, muscle ( buttock) wasting and irritability

• Other modes of presentation – short stature, anaemia ( iron deficiency) , screening, e.g. children with diabetes mellitus

Diagnosis

1- positive serology (IgA tissue transglutaminase and endomysial antibodies)

2- mucosal changes (flat mecosa , increased intraepithelial lymphocytes and a variable degree of villous atrophy and crypt hypertrophy) on jejunal biopsy

3- resolution of symptoms and catchup growth upon gluten withdrawal

Treatment – gluten free diet for life.

The incidence of small bowel malignancy ( lymphoma, carcinoma ) in adult hood is increased in coeliac disease, although a gluten free diet probably reduces the risk to normal.

Answer: A. Reassurance

Breast-Feeding Considerations: Phenytoin is excreted in breast milk; however, the amount to which the infant is exposed is considered small. The manufacturers of phenytoin do not recommend breast-feeding during therapy.

phenytoin, carbamazepine and valproate are probably safe

Q

baby 6 month show regurgitation after every meal he esophagus ph is low he is normally developing what is the Rx?

A. Close follow up

B. Surgical fundal

c. Esophageal manometry

A

Answer: A

no treatment is required may be because I think this is a case of normal physiological gastroesophageal reflux which happen in baby younger than 8months & presented with effortless regurgitation but otherwise the baby is normal

Gastrooesophageal reflux : is the involuntary passage of gastric contents into the oesophagus.

It is extremely common in infancy. It is caused by inappropriate relaxation of the lower oesophageal sphincter as a result of functional immaturity. A predominantly fluid diet, a mainly horizontal posture and a short intraabdominal length of oesophagus all contribute.

nearly all symptomatic reflux resolves spontaneously by 12 months of age.

Most infants with gastrooesophageal reflux have recurrent regurgitation or vomiting but are putting on weight normally and are otherwise well,
