A 13-year-old boy was diagnosed as having primary nephrogenic diabetes insipidus, and symptoms developed at 3 years of age. Subsequently he developed bilateral hydronephrosis and a neurogenic bladder. His pedigree could be explored back 5 generations and represented an inheritance as an X-linked recessive transmission factor. He was treated with indomethacin 2 mg/kg/day plus chlorothiazide 500 mg/day and this new treatment showed a markedly decreased urine output and increased urine osmolarity.

We report a rare case of diabetes insipidus following fire burn injury. Meticulous fluid balance and the use of carbamazepine resulted in her survival.

Lymphocytic hypophysitis is a rare inflammatory disorder in the pituitary gland. The lesion is usually confined to the adenohypophysis. Although the involvement of the posterior pituitary gland or the stalk is rare, such patients with diabetes insipidus have been reported. Surgery has been used to make the definitive diagnosis. Recent studies suggest, however, that the pathologic diagnosis may not be necessary always. We reported a case of Lymphocytic hypophysitis managed by methylprednisolone pulse therapy. A 50-year-old premenopausal woman with Lymphocytic hypophysitis and diabetes insipidus was treated with methylprednisolone pulse therapy. Her adenopituitary lesion disappeared and the diabetes insipidus resolved. The optimal management for patients with lymphocytic hypophysitis may be the high index of the suspicion prior to the extensive surgical resection. In addition, methylprednisolone pulse therapy may improve the clinical and MRI findings.

Two patients with post-traumatic diabetes insipidus (DI) are reported. One had suffered a fatal injury and the other a mild contusion without amnesia before DI developed. These two instances exemplify the wide spectrum of post-traumatic DI and, hence, the importance of ruling out DI even afer a mild closed-head injury.

Diabetes insipidus (DI) is characterized by excessive urination and thirst. This disease results from inadequate output of antidiuretic hormone (ADH) from the pituitary gland or the absence of the normal response to ADH in the kidney. We present a case of transient central DI in a patient who underwent a cardiopulmonary bypass (CPB) for coronary artery bypass grafting (CABG). A 44-yr-old male underwent a CABG operation. An hour after the operation, the patient developed polyuria and was diagnosed with central DI. The patient responded to desmopressin and completely recovered five days after surgery. It is probable that transient cerebral ischemia resulted in the dysfunction of osmotic receptors in the hypothalamus or hypothalamus-pituitary axis during CPB. It is also possible that cardiac standstill altered the left atrial non-osmotic receptor function and suppressed ADH release. Therefore, we suggest that central DI is a possible cause of polyuria after CPB.
