Central diabetes insipidus is a rare disorder that can result as a consequence of diverse etiologies, including malformations, autoimmune, infiltrative(e.g. neoplastic or histiocytosis) or traumatic processes, as well as mutations in the gene encoding arginine vasopressin. Idiopathic central diabetes insipidus is a diagnosis of exclusion, one that has been made less frequently through the decades. Idiopathic central diabetes insipidus in children and adolescent requires a frequent follow-up regimen using serial brain MRI and CSF examinations especially if an isolated pituitary stalk thickening or loss of a hyperintense signal in the posterior lobe is observed. Also, so-called "idiopathic" central diabetes insipidus warrants close follow-up to determine the etiology, especially if anterior pituitary hormone deficiencies are detected. We report a case of idiopathic central diabetes insipidus with growh hormone deficiency and loss of a hyperintense signal in the posterior lobe. He is a 13 years old. We are scheduled to follow-up with serial contrast enhanced brain MRI and CSF evaluation for the early detection of an evolving occult hypothalamic-stalk lesion.

Congenital hypopituitarism is a rare disorder with absence or reduction of hormones produced by the pituitary gland. The clinical manifestations are hypoglycemia, prolonged jaundice, hyponatremia, micropenis, underdeveloped clitoris, lethargy, convulsion, pallor, cyanosis, apnea, hypotension, temperature instability etc. in neonates and growth failure, delayed or absent puberty in older infants and children. We experienced a case of congenital hypopituitarism who was a 20-year-old male patient with short stature and delayed puberty. Combined pituitary function test revealed panhypopituitarism and magnetic resonance imaging of brain showed anterior pituitary aplasia and ectopic posterior pituitary gland.

The color change of maxillofacial silicone has been attributed to certain environmental factors such as exposure to the UV component of natural sunlight, wetting and drying of the elastomer, and surface abrasion resulting from the application and removal of cosmetics. The purpose of this study was to evaluate the color change of maxillofacial silicone (Silastic MDX4-4210) according to type of pigment (cadmium yellow, titanium white, cosmetic red), and UV absorber application method after 200, 400, and 600 hours of 350nm UV light irradiation. The results were as follows. 1. According to type of pigments, after 200 hours cosmetic red showed significantly larger color change than cadmium yellow and titanium white, and after 400 and 600 hours color change significantly decreased in the order of cosmetic red, cadmium yellow, and titanium white (p<0.05). 2. In the cadmium yellow group, after 200 hours, the non-treatment group showed significantly larger color change, but after 400 and 600hours, color change significantly decreased in the order of non-treatment, surface application and mixed group (p<0.05). 3. In the titanium white group, there was no significant color change difference between the three groups after 200 and 400 hours, but after 600 hours, the mixed group showed significantly smaller color change than the non-treatment and surface application groups (p<0.05). 4. In the cosmetic red group, there was significant decrease in color change in the order non-treatment, surface application and mixed group (p<0.05). From the results above, the effect of UV light absorber differed according to the type of pigment, but mixing UV light aborber with maxillofacial silicone is thought to give superior resistance against UV light irradiation in the long run.
