Abstract
Hypernatremic myopathy was rarely reported in the literature and its clinical features have never been well-described. We present a 22-year-old man who had adipsic hypernatremia manifested with progressive proximal muscle weakness and remarkably high creatine kinase level that has never been reported in the cases of hypernatremic myopathy. His initial presentations were similar to that of polymyositis without the evidence of central nervous system dysfunction and hypopituitarism. The serum level of sodium at the beginning of myopathy is the lowest known in the literature. All the clinical presentations in this patient resulted from a hypothalamic mixed germ cell tumor with sub-acute intra-tumoral hemorrhage.

Abstract
We describe a 21-year-old man presenting with proximal muscle weakness associated with hypernatremia. His manifestations other than muscle weakness included dry skin, loss of axillary and pubic hair, decreased libido and loss of thirst sensation. His serum sodium level was elevated to 169-171 mEq./l but all other electrolytes were normal. In addition, serum CK was elevated and an EMG study showed myogenic changes. Endocrinological studies revealed hypothalamic hypopituitarism, while MRI revealed a suprasellar mass. A partial correction of hypernatremia led to an immediate recovery of the muscle weakness as well as a normalization of both the serum CK level and EMG findings, suggesting a direct association between the muscle weakness and hypernatremia. The phosphocreatine/inorganic phosphorus (PCr/Pi) ratios in the resting calf muscle, obtained using 31P magnetic resonance spectroscopy (MRS), were very low during the state of muscle weakness, while they returned to nearly normal values after clinical improvement, suggesting that the muscle weakness in hypernatremic state was caused by a depletion of the intramuscular energy stores, probably due to an overworking Na-K pump to correct the intracellular electrolyte imbalance.

Abstract
Studies to assess the relationship between plasma arginine vasopressin concentration (Pavp) and plasma osmolality (Posm) were performed on an elderly patient with dementia who developed severe hypernatremia due to inadequate water intake following a debilitating hip fracture. Serum sodium concentrations were 174 and 196 mEq/L on two consecutive hospital admissions. During the second of these admissions, sequential measurements of Pavp and Posm were obtained as hypernatremia was gradually corrected. Pavp during this period was correlated with Posm (r = 0.887, P < 0.01), but was low despite the presence of hyperosmolality and volume depletion. Pavp decreased from 0.56 microU/mL to 0.18 microU/mL as Posm decreased from 396 to 338 mOsm/kg H2O. The regression line of this relationship intercepted the abscissa at 320 mOsm/kg H2O. Hypertonic sodium chloride infusion to reassess this relationship 2 days following the correction of hypernatremia increased Pavp only to 0.67 microU/mL while increasing Posm from 297 to 316 mOsm/kg H2O. Nevertheless, Pavp and Posm were significantly correlated (r = 0.937, P < 0.001). The slope of the regression line was 0.031, and Posm at the abscissal intercept was 292 mOsm/kg H2O. A similar increase in Posm from 290 to 310 mOsm/kg H2O during hypertonic sodium chloride infusion 11 days following the correction of hypernatremia increased Pavp to 1.95 microU/mL (r = 0.786, P < 0.05). The magnitude of the increase in Pavp at this time was equivalent to that previously observed in studies of normal subjects. The slope (0.048) and abscissal intercept (280 mOsm/kg H2O) of linear regression were also consistent with observations in studies of normal subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two unrelated boys (C.C. 13 years; J.W. 18 years) presenting with early puberty and episodes of aggressive behaviour were found to have hypernatraemia and hypodipsia. Plasma vasopressin (AVP) levels were inappropriately low in relation to plasma osmolality, but the patients did not have diabetes insipidus since 24 h urinary volumes were less than 1 litre and the maximal urinary osmolality was 1232 in C.C. and 950 in J.W. Plasma renin activity was elevated (greater than 2000 mg AI/1/h) although aldosterone concentrations were normal. Excretion of a water load (20 ml/kg) was delayed, but plasma renin and aldosterone fell with increased naturesis. An infusion of 0.85 mol/l saline produced a rise in AVP in C.C. but not in J.W. Insulin and hypotension resulted in the release of AVP in both boys suggesting a selective defect of osmoreceptor function. Hyperprolactinaemia and an exaggerated PRL response to TRH were also noted but no intracranial lesion was demonstrable on CT scan. These boys appear to have a hypothalamic syndrome with early puberty, hyperprolactinaemia, hypodipsia and osmoreceptor dysfunction which may be associated with aggressive behaviour.

Abstract
We evaluated water metabolism in 11 patients with hypothalamic-pituitary sarcoidosis. Seven patients had abnormal water metabolism: one had partial antidiuretic hormone (ADH) deficiency, one had severe ADH deficiency, one had severe ADH deficiency and deficient thirst, one had only deficient thirst, and three had excessive thirst. In four of the five with thirst disturbances, there was loss of congruence of osmotic thresholds for thirst and ADH release. Five of our patients presented with polyuria and polydipsia, but only two had true diabetes insipidus, whereas three had organic primary polydipsia with adequate endogenous ADH. That disordered thirst resulting in polydipsia was more common than true diabetes insipidus is at odds with previously held views on the prevalence of ADH deficiency in this condition.

Abstract
A 49-year-old man was submitted to neurosurgery for a cranio-pharyngioma. The lesion, which appeared to involve the antero-inferior wall of the third ventricle, caused lack of appropriate antidiuretic hormone (ADH) release in response to hypernatraemia and plasma hyperosmolality. The probable mechanism of this hypothalamic syndrome is suggested.

Abstract
The physiologic factors involved in vaseopressin (ADH) release and action are reviewed with emphasis on the interaction between osmotic and volume stimuli to the discharge of ADH. Abnormalities in reception of stimuli to ADH release, and in the impaired synthesis and release of ADH, are reviewed in relation to the causes of diabetes insipidus, and information on the biochemical changes which have been described in patients with nephrogenic diabetes insipidus is also discussed. We summarize the pathologic lesions and associated diseases found in 54 of our patients with diabetes insipidus. Criteria for establishing the diagnosis of diabetes insipdus are reviewed with emphasis on the dehydration test, including the importance of measuring plasma osmolality at the conclusion of water deprivation. Treatment of diabetes insipidus is briefly discussed with emphasis on the use of DDAVP and oral agents. The syndrome of inappropriate ADH secretion (SIADH) is reviewed including our experience with 39 patients. The differential diagnosis of SIADH, including the value of water loading and the measurement of ADH levels, is discussed. We comment on treatment of these patients including the use of investigational drugs. Lastly, we review the pharmacologic features and clinical relevance of some drugs which alter the release and action of ADH.

Abstract
Acute and chronic effects on the fluid balance of radio-frequency forebrain lesions were studied in the goat. Medial lesions which involved practically the entire anterior wall of the third cerebral ventricle cause persistent loss of thirst and lack of significant antidiuretic hormone (ADH) release in response to hypernatraemia and plasma hyperosmolality. As acute response to such lesions an uncompensated, temporary water diuresis was seen, which rapidly caused pronounced hypernatraemia and hypovolaemia. Lesions extending laterally to encroach upon the supraoptic nuclei resulted in persistent signs of weak, inappropriate ADH secretion (=impaired water diuresis, renal salt wasting, and pronounced hyponatraemia during hydration). Forebrain damage, mainly restricted to the septal region, caused hyperdipsia. In some goats, obvious post-lesioning increase in salt appetite was observed which could not be coreelated to the extent of their forebrain damage. The results are discussed in relation to hypothalamic syndromes in man and previous studies on central control of fluid balance in the goat.

Abstract
1. The effect on renal Na and water excretion of increasing the NaCl concentration of blood supplying the brain was investigated in conscious water-loaded sheep. Intracarotid infusion ot 4 M-NACl at 0-8 ml./min for 60 min was compared with equivalent intrajugular infusion. 2. A more rapid increase in renal Na excretion and urine osmolality occurred with the intracarotid infusions than with intrajugular infusions. 3. Intracarotid infusions of 2 M sucrose or fructose at 1-6 ml./min for greater increase in renal Na excretion, urine osmolality and a decrease in urine flow rate. 4. The results suggest that there are receptors in the brain sensitive to changes in extracellular tonicity which influence renal Na excretion. It is possible that changes in ADH secretion alone mediate the early natriuresis seen with intracarotid hypertonic infusions although an alternative concurrent mechanism cannot be ruled out.

Abstract
A physiological explanation for sustained hyperosmolality was sought in a patient with histiocytosis. During 23 days of observation with only sodium intake regulated at 100 mEq daily, elevation (mean 310 mOsm/kg of water) and fluctuation (range 298-323) of the fasting plasma osmolality were recorded. The presence of endogenous vasopressin was indicated by the patient's ability to concentrate the urine to as high as 710 mOsm/kg of water with a creatinine clearance of 84 cc/min, and by dilution of the urine in response to alcohol. The failure of increasing fluid intake to as high as 6.2 liters daily to lower the plasma osmolality indicated that deficient fluid intake was not solely responsible for the elevated plasma osmolality. Hypertonic saline infusion during water diuresis resulted in the excretion of an increased volume of dilute urine. The water diuresis continued despite a rise in plasma osmolality from 287 to 339. An isotonic saline infusion initiated during hydropenia resulted in a water diuresis which continued despite a rise in the plasma osmolality from 303 to 320. Stable water diuresis induced during recumbency by either oral ingestion of water or intravenous infusion of normal saline was terminated by orthostasis and resumed with the return to the recumbent position. Antecedent alcohol ingestion blocked the antidiuresis of orthostasis. The data are interpreted as indicating impairment of the osmoreceptor mechanism as the primary cause of the hyperosmolar syndrome. They also indicate that vasopressin secretion was regulated primarily by changes in effective blood volume. Chlorpropamide was found to be an effective treatment for the syndrome.
