Arterial hypertension can be treated by restoring nitric oxide deficiency

Prognosis
Due to the rarity of the disease, it is hard to estimate mortality rates or life expectancy. One 2003 study which followed 88 cases receiving two different kinds of treatment found that very few persons lived beyond age 20 and none beyond age 30. Incidence
Argininosuccinic aciduria occurs in approximately 1 in 70,000 live births. Many patients can now be detected on the newborn screen if their blood citrulline is elevated. References

The prominent knobs of bone at the costochondral joints of rickets patients are known as a rachitic rosary or beading of the ribs. The knobs create the appearance of large beads under the skin of the rib cage, hence the name by analogy with the beads of a Catholic Christian rosary. Causes
Causes include:
Rickets : Nodularity at costochondral junction (rachitic rosary). Scurvy : More angular costochondral junction with a sharper step-off (scorbutic rosary) and depressed sternum. Chondrodystrophy

Pathophysiology
Rachitic rosary is due to a deficiency of calcium resulting in lack of mineralization and an overgrowth of costochondral joint cartilage. The calcium deficiency may be caused by rickets or other causes of calcium deficiency such as hypoparathyroidism. Diagnosis
Management
