Two girls, one with septo-optic
dysplasia
and the other with posttraumatic brain damage, had the unusual combination of human growth hormone, thyrotropin, adrenocorticotrophic hormone, and
vasopressin
deficiencies that were associated with sexual precocity in one patient and early sexual maturation in the second patient, and of adult follicle-stimulating hormone and luteinizing hormone concentrations. At autopsy, the first patient had optic nerve aplasia, a normal pituitary gland, and some disorganization of myelinated fibers in the hypothalamus. The second patient had a normal thyrotropin and prolactin response to thyrotropin-releasing hormone, plus hyperphagia, deranged thirst mechanism, and temperature instability. These findings suggest that the lesion may be a defective hypothalamic regulation of pituitary hormone secretion. Congenital or traumatic hypothalamic-pituitary lesions may not affect all releasing factors or trophic hormones in a similar fashion.

The cause of a seventeen-year-old female patient with septo-optic
dysplasia
and pituitary dwarfism is presented. Mental retardatin and epilepsy, in addition to absence of the septum pellucidum, point to a widespread lesion of the central nervous system. There is unilateral hypoplasia of the optic nerve. She is of small stature. The dynamic pituitary tests point to deficiency of GH, TSH and ACTH, and an adequate reserve of prolactin, gonadotropins and
vasopressin
. TSH insufficiency is probably of primary pituitary origin.

We describe two sisters with chronic hypernatremia, lack of thirst, and inappropriate osmoregulated
vasopressin
secretion. Only one sister, who presented with microcephaly and developmental delay, showed signs of
dysplasia
of the midline structures (ie, septum pellucidum and corpus callosum) and a large intracranial cyst. Neither sister showed any signs of thirst, even when osmolality exceeded 337 mmol/kg. In both patients, the
vasopressin
secretion did not respond to either osmotic or nonosmotic stimuli or was suppressed by a water load. Plasma osmolality values returned to normal after treatment with forced hydration and a
vasopressin
analogue, desamino-D-arginine vasopressin. These findings indicate a severe defect in the hypothalamic osmoreceptors that control thirst and
vasopressin
secretion. To our knowledge, this is the first report of such a disorder in two sisters.

Hypothalamic pituitary function and growth hormone releasing hormone (GHRH) loading tests in two children with septo-optic
dysplasia
(SOD) revealed isolated GH deficiency in one and deficiencies of growth hormone, adrenocorticotropic hormone and
antidiuretic hormone
in the other. Secretion of GH was elicited in the first patient by single i.v. bolus administration of GHRH and after repetitive i.v. infusions of GHRH in the second. With these results we confirmed that the hypopituitarism in our patients with SOD was of hypothalamic origin. Both patients also had infantile spasms.

A patient with acquired von Willebrand's disease (type I) had both plasma cell
dyscrasia
and angiodysplasia of the intestine. Based on examination of the components of F VIII/von Willebrand's factor (VWF) and the results obtained following the administration of cryoprecipitate and DDAVP (1-desamino-8-D-
arginine-vasopressin
), it was suggested that the production and release of VIII/VWF was normal and the rapid disappearance from the circulation was related to adsorption by abnormal cells in the bone marrow. The relation of acquired von Willebrand's disease, plasma cell
dyscrasia
and angiodysplasia is discussed and the literature reviewed. Our patient is added to three previous reported cases of such an association of these three disorders.

We reported two infants with hydranencephaly and chronic hypernatremia. Their plasma sodium concentration gradually increased during the first week and remained between 150-160 mEq/L thereafter. They showed no signs of thirst. A water deprivation test demonstrated low urine osmolality and low plasma ADH concentration despite markedly elevated plasma osmolality in both cases. Urine was significantly concentrated when
vasopressin
was given. Thus, it was concluded that both thirst mechanism and ADH secretion were disturbed in these two cases. ADH producing cells, the thirst center and the osmoreceptor are all located in the hypothalamus. Radiographic measures showed
dysplasia
of the hypothalamus, providing the anatomical basis for their dysfunction.

Three transgenic mouse models which proved to develop endocrine tumours are reviewed and discussed. The neoplasms were induced through the production of the transforming oncoprotein simian virus 40 (SV40) large T-antigen. The SV40/metallothionein-growth hormone (MGH), the insulin/SV40 (INS/SV40) and the
vasopressin
/SV40 (AVP/SV40) transgenic mice models all developed endocrine tumours of pancreas mainly composed of insulin-producing B cells, with a minor PP cell component. In the pancreata of INS/SV40 and AVP/SV40 transgenic mice, non-tumour lesions (hyperplasia and
dysplasia
) were also described. AVP/SV40 transgenic mice presented tumour genesis in anterior pituitary too. The usefulness of transgenic mouse models in reproducing human pathology is outlined with special reference to genetically dependent tumours.

Apert syndrome and septo-optic
dysplasia
are rare congenital structural disorders which have not been associated previously; we report a female infant with this association. Brain sonography and computed tomography revealed agenesis of the septum pellucidum; optic hypoplasia was demonstrated by funduscopic evaluation. We postulate that an embryopathic factor, which manifests at 5-6 weeks gestation, may result in this new association. Transverse craniectomy was performed in the hope of preserving brain development. Neither hypopituitarism nor adrenal insufficiency was observed; however, clinical manifestations and laboratory data provided evidence of inappropriate
antidiuretic hormone
syndrome.

Insertion into the mouse genome of the hybrid oncogene made up of bovine
vasopressin
gene derived 5' upstream sequences and the coding sequences of SV40 large T-antigen promoted tumours in anterior pituitary and endocrine pancreas of mice bearing this transgene. In order to investigate the morphology of the steps in the neoplastic process, we used light and electron microscopy to study these organs in 42 animals belonging to the 3rd, 4th and 5th generations, subdivided into 4 age groups from 20 days to 100 days of life. Antibodies to large T-antigen were used to identify sites of expression of the hybrid oncogene, thus monitoring the steps in neoplastic transformation. Large T-antigen immunoreactivity was identified in dysplastic lesions of younger animals and in both dysplastic lesions and tumours of older mice. Insulin (100% of cases) and pancreatic polypeptide (25% of cases) immunoreactivities were revealed in pancreatic lesions but no hormonal immunoreactivity was detected in the pituitary lesions. The ultrastructural study confirmed that the majority cell population of the pancreatic neoplasms was B-type and that the anterior pituitary tumours were poorly granulated. The subcellular localization of large T-antigen immunoreactivity was investigated by the immunogold method and was confined to the heterochromatin of tumour cell nuclei. These findings provide evidence for the
dysplasia
-neoplasia sequence in the genesis of endocrine tumours of pituitary and pancreas of transgenic mice. The
vasopressin
-SV40 large T-antigen transgenic mice may therefore be an useful model for the study of endocrine cell oncogenesis.

Optic nerve hypoplasia is a developmental anomaly of the retina and optic nerves in which there is a reduction in the number of ganglion cells in the retina and of their centripetal fibers projecting through the optic nerve to the lateral geniculate body. The condition may be unilateral or bilateral and is frequently misdiagnosed as optic atrophy. In about 25% of cases, bilateral optic nerve hypoplasia is associated with a variety of cerebral malformations of which the commonest single disturbance is absence of the septum pellucidum (septo-optic
dysplasia
). Cerebral malformations and their endocrine accompaniments are also seen, though less frequently, in unilateral hypoplasia. The endocrine disturbances that may accompany optic nerve hypoplasia include growth hormone deficiency, adrenal insufficiency, hypothyroidism, and disturbances of
antidiuretic hormone
production. Precocious puberty and hypogonadism have also been observed. The prognosis of optic nerve hypoplasia depends upon the severity of the changes in the optic nerves and especially the degree of associated cerebral malformation. The finding of optic nerve hypoplasia should lead to thorough ophthalmologic, neurologic, and endocrinologic evaluation of the patient.
