What causes newborn hypercalcemia?
Causes of hypercalcemia Hypercalcemia can occur in very young infants due to excessive vitamin D action that occurs as a result of injury to skin or fat tissue or from genetic conditions. Hypercalcemia can also accompany other medical conditions, such as cancer.
What are the major causes of hypercalcemia?
Hypercalcemia is caused by:
- Overactive parathyroid glands (hyperparathyroidism).
- Cancer.
- Other diseases.
- Hereditary factors.
- Immobility.
- Severe dehydration.
- Medications.
- Supplements.
What is Rag doll Syndrome?
Hypotonia is a medical word for low muscle tone. If your baby has it, they will likely feel limp in your arms, like a rag doll. That’s why it’s also called floppy infant syndrome. Doctors can diagnose the condition in the first few minutes of life.
What causes Floppiness in babies?
Causes of hypotonia include: Brain damage or problems with how your baby’s brain formed during fetal development. Conditions that affect how nerves communicate with muscles. Conditions that affect muscles.
Which type of neonatal hypercalcemia is most common?
Hypercalcemia is total serum calcium > 12 mg/dL (> 3 mmol/L) or ionized calcium > 6 mg/dL (> 1.5 mmol/L). The most common cause is iatrogenic.
What is the most common cause of asymptomatic hypercalcemia?
The diagnosis often is made incidentally in asymptomatic patients. Clinical manifestations affect the neuromuscular, gastrointestinal, renal, skeletal, and cardiovascular systems. The most common causes of hypercalcemia are primary hyper-parathyroidism and malignancy.
Can hypertonia in babies be cured?

What causes high calcium in child?
Familial hypocalciuric hypercalcemia (an inherited condition that causes abnormally high levels of calcium in the blood) Hyperthyroidism (overactive thyroid) Kidney failure. Paget’s disease (a condition that affects the breakdown and formation of the bones)
How do you treat high calcium in babies?
Marked elevation of serum calcium may be treated with normal saline 20 mL/kg IV plus furosemide 2 mg/kg IV and, when persistent, with corticosteroids and calcitonin. Bisphosphonates are also increasingly used in this context (eg, etidronate by mouth or pamidronate IV).
Why is normal saline used in hypercalcemia?
The foundation of hypercalcemia treatment is isotonic saline hydration. This corrects the volume depletion caused by hypercalcemia-induced diabetes insipidus and concomitant nausea and vomiting. Saline infusion of three to six liters over 24–48 hours can lower calcium levels by 1–3 mg/dL.
What does a baby with hypertonia look like?
