The effect of DDAVP (1-deamino-8-D-arginine vasopressin), a synthetic analogue of vasopressin, was studied in twelve patients with acute postoperative cranial diabetes insipidus (D.I.). The most severe D.I. occurred in four cases following total removal of tumor (3 pituitary microadenoma, 1 dermoid cyst). The urinary volume over 1000 ml per hour in these four cases could not be controlled by DDAVP but could be controlled by drip infusion of aqueous pitressin (AP) and pitressin tannate in oil (PTO). DDAVP was effective when the urinary volume was decreased in under 500 ml per hour. The mild D.I. occurred in four cases after partial removal of tumor (3 craniopharyngioma, 1 pituitary microadenoma). These four cases could be controlled by drinking water only during one or two postoperative weeks. DDAVP was administered in doses of 10 to 30 microgram two times daily after 2 or 3 postoperative weeks and the urinary production was normalized. The four patients developed D.I. after removal of functioning pituitary microadenoma operated by transsphenoidal route. These four cases were treated with drip infusion of AP and PTO during one or two weeks after the operation and were effectively treated with 5 to 15 microgram of DDAVP intranasally every 8 to 12 hours one or two weeks after the operation. Nine cases in 12 cases with postoperative D.I. became chronic D.I. The maintenance dose of DDAVP gradually lessened in accordance with decreasing urinary volume except the two cases of craniopharyngioma. No side effect was experienced for 19 months of treatment.

Methionine-enkephalin-like substance was measured in CSF by the radioreceptor-assay established by Furui et al. Samples were obtained from preoperative 20 cases, in which were included 11 cases of pituitary adenoma, 3 cases of craniopharyngioma, 2 cases of pseudtumor cerebri and 4 normal cases, by lumbar puncture. Also postoperative measurement of this substance and pre- and postoperative measurement of ACTH in plasma were performed in 5 cases of Cushing's disease. Five ml of CSF was chromatograpied on two successive columns, lyophilized and assayed for opiate receptor affinity against 3H-dihydromorphine. Measured values were expressed as methionine-enkaphalin equivalents using the displacement curve run in parellel. Methionine-enkephalin-like substance level ranged from less than 0.5 to 20.0 pmoles/ml in all cases and mean value was 2.6 pmoles/ml (+/- 1.0 S.E.) in normal subjects. In Cushing's disease the level was not elevated preoperatively (2.1 +/- 0.3) and did not significantly decrease postoperatively (1.6 +/- 0.4 pmoles/ml) in contrast to the decrease of ACTH in plasma. It is suggested that methionine-enkephalin-like substance in CSF is not derived from ACTH producing cells of pituitary gland. One case of craniopharyngioma showed very high value. This case revealed diabetes insipidus at sampling. The possibility of participation of methionine-enkephalin in secretion of antidiuretic hormone was discussed.

Commercial preparations of vasopressin for the treatment of diabetes insipidus are not available in Mexico. Besides, the hormone is useless in the nephrogenic variety. In the department of Endocrinology at the Hospital Infantil de Mexico, a preparation containing hydrochlorothiazide, aminopyrine and potassium chloride, which reduces urinary volumes in about two thirds, is employed in all varieties of the disease. Growth in stature was investigated in 44 patients under treatment, attending the Endocrine Outpatient Clinic since 1967 for a period of 2 to 12 years. Clinical material included 29 males and 15 females. There were 23 idiopathic, 7 histiocytosis, 5 nephrogenic, 4 craniopharyngiomas, 2 psychogenic polydipsia, 2 traumatic and 1, as a sequel of tuberculous meningoencephalitis. Six idiopathic, 2 nephrogenic, 2 traumatic, 1 histiocytosis, and 1 psychogenic proceeded between percentiles 3 and 97, parallel to the nearest line of reference along the whole period of study. Two nephrogenic, 2 histiocytosis, 1 psychogenic, 1 post-meningoencephalitis and 14 idiopathic, grew below the third percentile, but parallel to it. One nephrogenic, 4 histiocytosis, 4 craniopharyngioma and 3 idiopathic progressively departed from the initial centile. Two of the latter had growth hormone deficiency, and 1 had been very irregularly treated. It is concluded that the therapy employed limits stature impairment but does not produce catch-up growth. Accordingly, it is proposed that the treatment of diabetes insipidus should be started as early as possible, and that if progress in stature is appreciably deteriorated, the presence of additional pathology should be suspected.

The growth and endocrine sequelae of 75 children (33 girls and 42 boys) with craniopharyngioma, treated from 1973 to 1994, were studied by retrospective review and by follow up assessment in 66 survivors, with a mean time from initial surgery of 6.7 years (range 1.5 to 19.8 years). Although infrequently complained of, 71% of patients had symptoms to suggest an endocrinopathy at diagnosis. After surgery, multiple endocrinopathies were almost universal, such that 75% of children had panhypopituitarism at follow up. Hypoadrenal crises in association with intercurrent illness contributed significantly to morbidity and mortality, as did the metabolic consequences of concomitant antidiuretic hormone (ADH) insufficiency and absent thirst. Final height in 25 patients was significantly below genetic target height, particularly in the girls, with loss of height potential occurring during the pubertal years. The endocrine morbidity associated with craniopharyngioma and its treatment remains high but manageable with appropriate hormone replacement. However, the combination of ADH insufficiency and an impaired sense of thirst following aggressive surgery and severe hypothalamic injury remains one of the most complex management problems.

In a retrospective study, the intra- and early postoperative data of 39 children with 46 operations for craniopharyngioma were analyzed. Diabetes insipidus (DI) occurred in 30 out of 32 cases without preoperative evidence of DI. We observed that all children who did not have a pituitary stalk preserved and 5 out of 7 patients with preserved pituitary stalk developed DI within 18 h of surgery. Short-term inappropriate secretion of antidiuretic hormone (SIADH) occurred in 2 children, but was quickly followed by DI. The time of onset of DI and SIADH did not correlate with sex, age, body weight, location of tumor, or duration or extent of surgery. Parenteral desmopressin was an effective treatment for intra- and postoperative DI. The duration of the clinical effect of desmopressin administration varied in different patients between 4 and 23 h. An approach to the immediate intra- and postoperative management of children with craniopharyngioma is presented.

Diabetes insipidus (DI) is an uncommon but important complication in the neurosurgical population. This retrospective study aimed to determine the incidence, profile and outcome of patients admitted to an 18-bedded neurosurgical intensive care unit who developed DI. The overall incidence was 3.7% (29/792 admissions). Aetiologies included subarachnoid haemorrhage (12/29), severe head injury (11/29), post-surgical excision of craniopharyngioma or pituitary adenoma (5/29) and acute haemorrhagic stroke (1/29). All patients were treated with a regime of fluid replacement, electrolyte correction, parenteral or intranasal desmopressin (DDAVP), or parenteral pitressin. Overall mortality was 72.4%. There were no deaths in the patients who underwent excision of tumours. Complications included acute pulmonary oedema, hypernatremia and hypokalaemia. The development of DI was found to be associated with impending brain death and mortality in the majority of patients with subarachnoid haemorrhage and severe head injury. However, careful diagnosis and management of DI after hypothalamo-neurohypophyseal surgery did not result in any permanent neurological sequelae.

Sinonasal teratocarcinosarcoma (SNTC) is a rare, aggressive, histologically heterogeneous neoplasm of the paranasal sinuses and nasopharnyx of adults that is composed of variably benign or malignant neuroepithelial, epithelial, and mesenchymal elements. Occasional cases show intracranial extension and may be operated on by neurosurgeons and encountered by neuropathologists who may not be familiar with the entity. STNCs have not previously been associated with functional hypersecretory status. We report a 59-year-old male who presented with headache and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and was subsequently found to have a bulky tumor of the frontal and ethmoid sinuses with focal dural invasion. The tumor was predominantly composed of olfactory neuroblastoma areas (90% of tumor) admixed with unusually well-developed craniopharyngioma-like mature squamous epithelium and ghost cells ( 10% of tumor). Scattered neuroblastoma tumor cells showed strong immunoreactivity with antibodies to arginine vasopressin, supporting ectopic hormone secretion by the tumor. While the coexistence of neuroectodermal and oral ectodermal-like differentiation in SNTCs is characteristic, in our case it was developed to an extreme functional and morphologic degree and was unassociated with other mesenchymal or epithelial elements often found in these complex tumors. SNTCs with limited differentiation have prompted controversy in classification.

Ultrasonography revealed a suprasellar tumor in a fetus at 28 weeks of gestation. The male newborn, delivered 10 weeks later, was operated at the age of 17 days, and a craniopharyngioma was completely removed. Intraoperatively, inappropriate secretion of antidiuretic hormone occurred and was followed by diabetes insipidus causing imbalance of fluid and electrolytes. The tumor recurred and was totally removed 1 year later. Further development was uneventful and, at the age of 8 years, the boy is in generally good mental and physical condition except for a left-sided hemiparesis. In contrast to the poor outcome of neonatal craniopharyngioma reviewed in the literature, this case may encourage radical surgery even in the very young.

Central diabetes insipidus is clinically masked in dialysis patients. We report a 12-year-old girl receiving a living-related donor graft for renal failure from Alport syndrome, in whom a craniopharyngioma had been resected 6 months before transplantation. Pretransplant evaluation had documented central hypothyroidism, growth hormone deficiency, and presumptive hypogonadotropic hypogonadism. The corticotropin-releasing factor test had been normal. Four hours after transplantation, urine output exceeded 1,000 ml/h without diuretic therapy. Serum sodium concentration was 155 mmol/l, serum osmolality 333 mmol/kg, and plasma antidiuretic hormone 4.9 ng/l, while urine osmolality was 233 mmol/kg. Desmopressin acetate was started by continuous intravenous infusion at 1 microgram/day. Serum electrolytes rapidly normalized, urine output stabilized at 2 l/day. The patient was discharged 4 weeks after transplantation with good allograft function, receiving intranasal desmopressin acetate 10 micrograms twice daily. Pre-existing central diabetes insipidus is unmasked after successful kidney transplantation, leading to rapid dehydration and hypernatremia, which can be prevented by prompt institution of desmopressin therapy.

Central diabetes insipidus (DI) can be the outcome of a number of diseases that affect the hypothalamic-neurohypophyseal axis. The causes of the condition can be classified as traumatic, inflammatory, or neoplastic. Traumatic causes include postoperative sella or transection of the pituitary stalk, while infectious or inflammatory causes include meningitis, lymphocytic hypophysitis, and granulomatous inflammations such as sarcoidosis and Wegener's granulomatosis. Various neoplastic conditions such as germinoma, Langerhans cell histiocytosis, metastasis, leukemic infiltration, lymphoma, teratoma, pituitary adenoma, craniopharyngioma, Rathke cleft cyst, hypothalamic glioma, and meningioma are also causes of central DI. In affected patients, careful analysis of these MR imaging features and correlation with the clinical manifestations can allow a more specific diagnosis, which is essential for treatment.
