The now nine years old girl with growth retardation, started to be ill with otitis and then diabetes insipidus of central origin at 1974. A treatment with lysin-vasopressin is prescribed. The PNEG in May 1976 shows a little, pea like, suspicious, supra-sellar nodule who is not surgically explored since they was no ophtalmologic symptoms and because a normal CT scan. Corticoid and thyroid substitutive therapy is added until September 1977 when the general status becomes impaired and vomiting starts. Also because some visual loss, a new neuroradiological study is performed showing a supra-sellar tumour and a fourth ventricle mass. The CT scan asserts the double intracranial expansive process and a posterior fossa craniotomy is done with subtotal resection of a vermian tumour and Torkildsen drainage. The histology is : Immature Dysembryoma (seminoma type) or germinoma. The follow-up was good under hormonal care. X Rays Therapy over the posterior fossa, the suprasellar region, the brain and the spinal channel was instaured. Four months later, the CT scan shows normal sized ventricles and no tumour mass at all. This case gives the authors opportunity for comments and to study the concerned literature.

A 3 1/2-year-old girl with a huge optic glioma was reported. On February 26, 1978, she was hospitalized for signs of increased intracranial pressure, namely headache, vomiting and consciousness disturbance. Before admission she did not complain of her visual disturbance. A huge mass lesion in the subfrontal-suprasellar region was found by neuroradiological examination. The operation was performed on March 7, 1978, and the tumor arising from the right optic nerve, about 170 grams in weight, was totally removed in piecemeals. Histopathological diagnosis was pilocytic astrocytoma. Immediately after operation diabetes insipidus and hypernatremia developed, but two months later these symptoms disappeared. Post-operative CT scan demonstrated no mass lesion in the subfrontal-suprasellar region. After radiation therapy, she was discharged with slight left hemiparesis on August 31, 1978. Though her right eye was blind, visual acuity remained 0.2 in the left eye. No other neurologic deficits could be found.

A veterinary technician while opening a package was accidentally exposed to a commercial canned product formulation containing insecticides and solvents. The patient was twice briefly treated and released as an outpatient from 2 different hospitals on the first and second day after the exposure. However, on the fourth day, as some of the symptoms (headache, nausea, vomiting, diarrhea, difficult breathing) persisted, the patient was admitted to another hospital. The patient was treated for exposure to organophosphates and solvents and was released after 13 days. The patient developed diabetes insipidus, a condition which lasted for approximately 1 year. The cause of the temporary development of diabetes insipidus is not understood. There is a need to prevent and minimize such accidental exposures in future.

Apomorphine, a centrally-acting emetic, was administered subcutaneously (50 micrograms/kg) to nine normal subjects (four male, five female; aged 22-36 years) and four patients with idiopathic diabetes insipidus (DI) (one male, three female; aged 24-49 years). In the normal subjects this stimulus caused nausea (and vomiting in seven of nine) with a latency of 9.5 +/- 0.9 min which was followed by a large increase in plasma arginine vasopressin (AVP) concentration (from 0.9 +/- 0.2 pmol/l to 249 +/- 104 pmol/l at 15 min after the onset of symptoms; mean +/- SEM, P less than 0.01). There was a small but significant increase in plasma oxytocin (OXT) concentration (from 1.6 +/- 0.4 pmol/l to 6.2 +/- 3.4 pmol/l; P less than 0.05). Mean arterial pressure (MAP) fell slightly (from 87 +/- 1.9 mm Hg to 71 +/- 4.4 mm Hg; P less than 0.05) 15 min after the onset of nausea; there was no change in blood haematocrit or plasma osmolality and sodium concentration. In the DI patients apomorphine produced nausea (with vomiting in three of four) with a latency of 10.0 +/- 1.4 min but failed to cause an increase in either plasma AVP or OXT. In the DI patients the fall in MAP did not reach statistical significance (83 +/- 4 mm Hg to 71 +/- 11 mm Hg); there was also no change in haematocrit, osmolality or sodium concentration. Ipecacuanha, an emetic with both peripheral and central actions, was administered orally to seven normal subjects (three male, four female; aged 22-36 years) six of whom also underwent apomorphine tests.(ABSTRACT TRUNCATED AT 250 WORDS)

Germinomas in childhood may arise in both the suprasellar and pineal region, and outcome has been reported to be worse for suprasellar germinomas with a 5-year survival rate of 20% as compared to 60% for pineal germinoma. To determine the factors impacting on outcome, the results of a uniform treatment approach were evaluated and included primary surgical debulking (PSD) and systemic craniospinal axis radiation (CSRT) for suprasellar germinomas. Between 1976 and 1985 ten consecutive patients (seven females, three males) with the pathologically confirmed diagnosis of suprasellar germinoma were treated. Outcome was compared to four male patients with pineal germinoma treated over the same time period and series of patients reported in the literature. At diagnosis the mean age of patients with suprasellar germinoma was 13.9 years (range, 8.9 to 9.4 years). Symptoms were present for a mean of 18 months (range, 2 to 72 months) prior to diagnosis and included diabetes insipidus, anterior pituitary dysfunction, decreased vision, headache, vomiting, and diplopia. Staging studies, including myelography (n = 4) and cerebrospinal fluid cytology (n = 7), disclosed dissemination in only one child. Surgical treatment included biopsy in three cases, partial resection in five, and total resection in two; no permanent postsurgical complications were noted. The mean radiation therapy dose to the tumor site was 4953 cGy (range, 4400 to 5250 cGy) and to the spine 3354 cGy (range, 3000 to 4000 cGy). Patients were followed for a mean period of 5.1 years (range, 1.9 to 10.5 years). One patient with SG who did not receive treatment initially developed a pineal tumor after diagnosis; she was treated with PSD and CSRT and is asymptomatic 5 years later. All the remaining patients are alive and remain disease-free. Surgical resection and CSRT results in excellent disease control for children with suprasellar germinomas, and outcome is similar to those patients with pineal germinoma.

A 59-year-old woman with metastatic breast carcinoma presented with weight loss, vomiting, and polyuria. Basal endocrine testing revealed low levels of thyroxine, cortisol, and gonadotropins, and the presence of diabetes insipidus. Direct stimulation of the pituitary with hypophysiotropic hormones indicated intact pituitary reserve. Insulin-induced hypoglycemia, however, failed to increase plasma cortisol or growth hormone levels significantly. On computed tomographic scanning, a lesion was found in the area of the hypothalamus. Thus, a functional abnormality of the hypothalamic-pituitary axis causing clinically significant hypothalamic hypopituitarism was not clearly apparent following administration of hypothalamic releasing factors but was demonstrable with indirect stimulation via insulin-induced hypoglycemia. Insulin-induced hypoglycemia remains an important diagnostic test in the evaluation of hypopituitarism.

The etiology, epidemiology, pathophysiology, and complications, therapy, and prognosis of hypernatremic (hypertonic) dehydration in infants are briefly discussed. The most likely causal condition for hypernatremic states in infants is enteric disease, because the symptoms of diarrhea and vomiting result in water loss and inability to take in water for replenishment. Other causes include dubious feeding practices, diabetes mellitus, diabetes insipidus, and maladroit diagnostic and therapeutic maneuvers, including administration of radiologic contrast medium or hypertonic sodium bicarbonate or mannitol infusions, or the use of salt solutions as an emetic. Epidemiologically, 2 factors are apparent: high saline diet and winter season. The clinical hallmarks of hypernatremic disturbance are relative preservation of circulation and early presence of neurologic symptomatology. Renal tube necrosis is also occasionally encountered. Therapy is rehydration, but the bone of contention is the technique for replacing water in the face of the fact that water administered without electrolyte causes the brain to swell and frequently results in convulsions. The management of hypernatremic dehydration begins with a replenishment phase if neither shock nor apparent anuria is present. The principle is to replenish the body slowly, and 48 hours has been chosen as the target, so that for volume the deficit plus 2 days of ongoing losses should be allocated. However, the sodium and other ion contents are derived solely from the deficit, without factoring the 2-day maintenance period. A recipe for rehydration fluid is presented.

The authors report a case of histiocytosis X which presented with neurological manifestations in a 20 year old man: episodes of headache with vomiting, followed, three months later, by the development of paralysis of the right 6th and 7th cranial nerves associated with nystagmus. The CT scan revealed a tumour-like lesion on the floor of the IVth ventricle with a long axis of 18 mm. The chest x-ray revealed diffuse nodular opacities in the pleural and apical regions with features suggestive of histiocytosis X. The diagnosis was confirmed by surgical biopsy of the typical pulmonary nodules which were rich in histiocytes with X bodies on electron microscopy. The neurological signs disappeared after one month of treatment with Prednisone (1 mg/kg/day) and Vincaleukoblastine (10 mg/week). By the 3rd month, the pulmonary lesions were reduced and the intra-ventricular formation had regressed by 40%. In the authors' series of 29 cases of confirmed histiocytosis X in adults, the present case is the only one with a clinical neurological presentation, apart from 3 cases of diabetes insipidus. A review of the literature confirms the rarity of this type of presentation. The suggestion of the diagnosis by the chest x-ray appearance enabled a dangerous neuro-surgical operation to be avoided.

The etiology of persistent hypokalemia and renal potassium loss was investigated in three children. Each had normal blood pressure but low plasma aldosterone values in relation to elevated plasma renin activity. None had a history of licorice abuse, laxative or diuretic use, persistent vomiting or diarrhea, pyelonephritis, or diabetes insipidus. Additional studies in one patient showed low prostaglandin E excretion and a normal platelet aggregation response to epinephrine and ADP. Although certain aspects of this condition resemble Bartter syndrome, the low concentrations of aldosterone and the absence of evidence for mineralocorticoid excess suggest a previously undescribed syndrome.

A retrospective analysis was performed to study the fluid and sodium status of patients undergoing transsphenoidal surgery (TS) for Cushing's disease. We evaluated the time of onset, duration, and relative incidence of isolated hyponatremia and identified possible factors associated with it. Of 58 patients that underwent TS over 1 yr, 52 without postoperative diabetes insipidus or volume depletion were studied. Isolated hyponatremia after TS for Cushing's disease occurred in 21%, and symptomatic hyponatremia (plasma sodium, < or = 125 mmol/L) with new onset headache, nausea, and emesis occurred in 7.0% of all operated. These later patients escaped monitoring and intervention for 24 h. The development of hyponatremia began early in the postoperative period and progressed slowly over 7 days. Maximum antidiuresis occurred on postoperative day 7. Vasopressin levels measured in two patients while hypoosmolar suggested that unregulated vasopressin release contributed to the hyponatremia. Cortisol levels, glucocorticoid replacement, and pituitary adenoma size were similar in normonatremic and hyponatremic patients. Patients combining a history of an estrogenic milieu and documented posterior pituitary trauma at surgery experienced lower nadir plasma sodium. All hyponatremic patients were fluid restricted, and none developed progressive neurological symptoms, morbidity, or mortality. We speculate that the mild degree and slow rate of development of hyponatremia and/or active monitoring and intervention contributed to the good outcome.
