A single case of gastric plasmacytoma showing unusual clinical and pathological features is described. The patient had gluten sensitive enteropathy, and showed increased circulating IgA levels prior to gastrectomy. Progression of the disease was associated with both K and L light chain proteinuria, hypoalbuminaemia, and
vasopressin
resistant
polyuria
. Pathological investigation revealed the coexistence of IgA secreting soft tissue plasmacytoma, with IgG secreting myeloma. The significance of these findings is discussed.

Studies were carried out in the rat to detemine if hypothalamic lesions which caused polydipsia and
polyuria
had their effect mediated through an alteration of the ability of the
neurohypophyseal
system to release ADH. Rats with medial preoptic lesions hadincreased water intake while on ad libitum access to water and slightly impaired ability to conserve water following dehydration, but with no impairment of urine-concentrating ability. These were associated with an increase in plasma osmolality both during ad libitum fluid intake and after dehydration. Urinary ADH excretion was at leastas great as in shamoperated controls during ad libitum water intake, but failed to increase during dehydration in spite of a marked increase in plasma osmolality. Pituitary ADH content did not differ from control animals either during ad libitum water intake of after dehydration. Animals with lesions in the lateral preoptic and septal areas did not differ from control animals during ad libitum fluid intake and after dehydration even though lateral preoptic lesions produced polydipsia. In all animals, lesions were remote from the supraoptic nuclei, which showed no histological evidence of damage. It is concluded thatareas of the central nervous system away from the supraoptic nuclei are involved in the regulation of both water intake and ADH release.

The age-dependent polydipsia and
polyuria
observed in SWR/J mice was found to be caused by relative inability of the kidneys to respond to
antidiuretic hormone
(
ADH
), resulting in a concentrating defect, which persisted even following Pitressin injection or water deprivation. Posterior pituitaries contained large amounts of
ADH
, which was also found in the urine and increased in output following water deprivation, indicating normal, or above normal synthesis and release of
ADH
. Kidneys of polydipsic SWR/J mice weighed more than those of normal strains and sometimes contained a lesion in the medullary area. No clear relationship was found between the size of the lesion and water intake.

1. A patient with
polyuria
in whom diabetes insipidus had been diagnosed was treated with Pitressin. Resistance to this therapy developed after 18 months and a circulating antibody to
vasopressin
was then demonstrated. Withdrawal of therapy led to a fall in titre of the antibody and an increase in maximal urinary concentration. 2. The antibody to
vasopressin
was associated with the IgA fraction of the serum immunoglobulins and its characteristics are described.

We describe a case of Cushing's syndrome caused by a phaeochromocytoma secreting corticotrophin-releasing hormone (CRH) and corticotrophin (ACTH). A 49-year-old white woman presented with a 1-month history of lower limb oedema, polydipsia and
polyuria
. Physical examination revealed a patient with plethoric facies, lanugo-type facial hair, central obesity, red abdominal striae, lower limb oedema, and blood pressure of 210/115 mmHg. Laboratory studies showed high plasma ACTH and markedly elevated urinary cortisol excretion that suppressed more than 50% with high-dose dexamethasone administration. Computed tomographic scan of the abdomen showed a 4-cm left adrenal tumour. Catecholamines and metabolites were markedly increased in a 24-hour urine collection. Results of venous catheterization studies showed that CRH and ACTH were secreted by the tumour. In addition, with ovine CRH administration, inferior petrosal sinus sampling showed pituitary secretion of ACTH. Left adrenalectomy resulted in complete remission of Cushing's syndrome. Light microscopic and immunohistochemical studies revealed a phaeochromocytoma that produced CRH, ACTH and
vasopressin
. RNA studies showed that this tumour, in contrast to normal adrenal and other reported phaeochromocytomas, transcribed a lone pituitary-sized (1200 nucleotide) pro-opiomelanocortin mRNA. This is the second reported case of a CRH-secreting phaeochromocytoma.

Brain death is associated with loss of hypothalamic, pituitary and brain stem function resulting in apnea, bradycardia and hypotension, poikilothermia, and diabetes insipidus. In order to preserve body functions mechanical ventilation is continued with the aim to maintain an arterial partial pressure of oxygen of more than 100 mmHg. Previous fluid restrictions and the application of diuretics during the treatment of high intracranial pressure frequently result in dehydration. Progressive vasodilation may induce severe hypotension and fluid replacement with cristalloids and if necessary colloids may be called for until the central venous pressure reaches 10 cm H2O. Continuous substitution of potassium and the use of hypotonic solutions such as glucose 5% may avoid hypokalaemia and hypernatraemia, respectively. Inotropic support with dopamine (5-10 micrograms/kg.min) or adrenaline (0.01-0.1 micrograms/kg.min) may be needed to maintain normal mean arterial blood pressure (65 mmHg).
Polyuria
(5000 ml/24 h) can be treated by continuous intravenous infusion of
antidiuretic hormone
(0.5-2-10 U/h). Hypothermia must be prevented by warming all fluids (37 degrees C) and covering the patient with heat saving blankets.

1. A symptomatic diuresis,
polyuria
, sometimes accompanies paroxysmal tachycardias in man. A study was undertaken in patients with inducible supraventricular tachycardia, irrespective of the symptom of
polyuria
, to measure simultaneous changes in urine output and plasma hormone levels during the arrhythmia. 2. During 14 episodes of induced tachycardia in 10 patients, there was a significant increase in mean urine flow, which was independent of the state of patient hydration. During a mean tachycardia duration of 30 +/- 3 min, the mean group urine flow increased from 3.2 +/- 2.3 ml/min to 7.6 +/- 3.7 ml/min (P less than 0.001). This was characterized by a consistent increase in free water excretion and a variable increase in sodium excretion. 3. The plasma atrial natriuretic peptide level (five patients) significantly increased from 7.6 +/- 4.6 pg/ml to 34.6 +/- 21.7 pg/ml (P less than 0.02) during the arrhythmia. There was no significant change in the plasma
arginine-vasopressin
level and a non-significant reduction in plasma renin activity. 4. This study has shown that induced supraventricular tachycardias in man are accompanied by a significant diuresis. The mechanisms responsible remain unknown, but do not appear to involve the plasma
arginine-vasopressin
level alone.

Diabetes insipidus (DI) is a disorder characterized by
polyuria
, polydipsia and increased thirst [1] while pituitary DI is a syndrome that is known to result from deficient release of the
antidiuretic hormone
(
ADH
) [2,3]. Trauma to the neurohypophysis (operational or accidental) is the most common cause of DI. Primary or metastatic intracranial tumors are the second most common cause of DI. Among the less frequent causes are the granulomatous lesions or infections of the central nervous system, drugs and vascular lesions [2]. In 30-40% of the patients, there is no identifiable cause (idiopathic DI). Idiopathic thrombocytopenic purpura (ITP) is an immunologically mediated destructive thrombocytopenia. The clinical diagnosis is made after excluding the presence of other disorders that are known to be associated with shortened platelet survival [4]. In this paper two cases of DI and ITP are described.

A 44-year-old female with 16-year history of rheumatoid arthritis visited Akiru Hospital with complaints of a thirst, a dry mouth and a general fatigue. One week prior to admission, the patient manifested excessive thirsty feeling, a body weight loss and a sleepless by the
polyuria
. She has been given 5-10 mg of prednisolone and 240 mg of lobenzarit disodium (CCA) in a day for 11 months. A hematologic examination showed no abnormality, and the examination of her serum showed the following values: BUN, 9.3 mg/dl; creatinine, 0.9 mg/dl; sodium, 139 mEq/l; chloride, 102 mEq/l; potassium, 3.9 mEq/l; osmolality, 290 mOsm/l. Plasma
antidiuretic hormone
(
ADH
) level increased slightly (6.0 pg/ml). Examination of her urine revealed specific gravity, 1.005; no trace of glucose, protein, blood and ketones; normal sediment; and osmolality, 209 mOsm/l. The patient was given exogenous
ADH
(10 units of
vasopressin
tannate in oil, intramuscularly) to obtain a diagnosis, and she was found to be unable to concentrate her urine more than 1.008 in the specific gravity. A water restriction, as a test for diabetes insipidus, also failed to concentrate her urine in the specific gravity and in the osmolality. Together with these findings, the patient was diagnosed to be a diabetes insipidus, and CCA was seemed to account for the disease. This unfavorable effect of CCA appeared to be reversible, since the patient recovered her urinary concentrating ability after the medication of CCA was discontinued.

A thirty-year-old male patient suffered subarachnoidal haemorrhage from an angioma positioned in the cranio-cervical transition. After rebleeding twice the patient developed a hydrocephalus internus malresorptivus and excessive natriuresis and
polyuria
, accompanied by depressed renin activity and extremely low aldosterone plasma levels. Neither fluid restriction and sodium substitution, nor administration of hydro-chlorothiazide/indomethacin affected natriuresis and
polyuria
. It was only after treatment with fludrocortisone-acetate/hydrocortisone that hyponatraemia and
polyuria
were resolved. At the same time a ventriculo-peritoneal shunt was applied. Differential diagnosis excluded the syndromes of inadequate
antidiuretic hormone
secretion, renal and cerebral diabetes insipidus, osmotic receptor hypofunction, chronic renal dysfunction and tubular necrosis. Natriuresis and
polyuria
developed under dexamethasone therapy. Since patient history, physical examination and laboratory criteria could not explain the electrolyte and fluid imbalance, this might be attributed to the hydrocephalus. Similar disturbances have been reported from other patients with intracranial disorders. Mechanical pressure exercised on the hypothalamus might cause the disturbance of fluid and sodium balance. Assuming a cerebral salt wasting syndrome, a putative natriuretic factor coming from the brain or an imbalance in the cerebral renin-angiotensin-system, as described in rats and dogs, must be discussed.
