Dwarfism • Pituitary dwarfism or dwarfism is a condition characterized by growth and development disorders caused by insufficient secretion of pituitary somatotrope hormone (growth hormone or GH).
Pituitary dwarfism may be caused by: • Genetic mutations – specific investigations are needed in order to determine the specific genetic mutations that can cause pituitary dwarfism occurrence. • Trauma (including surgery) of the pituitary gland • Tumors, trauma or irradiation of the central nervous system • Leukemia • In most cases the cause of pituitary dwarfism is unknown – idiopathic.
Symptomps • Children with pituitary have an abnormal slow growth rate • Due to deficient degradation of fat, • In patients with pituitary dwarfism, protein synthesis is diminished and the muscle mass is proportionally decreased than in normal individuals of the same age. • Patients may have a normal sex • Intelligence is mostly normal • The head and limbs are too small, but proportionate, • Pigmentation spots, freckles and fine wrinkles can be present on the facial skin.
