1/113. A case of fatal salt water intoxication following an exorcism session.

    In response to a recent article published in this review, we present in this paper, an unusual case of fatal salt water intoxication. In this case, we point out three special features, the type of water ingested, the physiopathologic consequences of the ingestion and the very strange context of occurrence. This complex case allows us to point out complications due to salt poisoning and others caused by water intoxication.

2/113. death from hyponatremia as a result of acute water intoxication in an Army basic trainee.

    Several reports during the past 15 years have described hyponatremia as a result of excessive water intake by athletes during endurance races. The high rates of fluid consumption have been attributed to the desire of athletes to prevent heat injury. The military has adopted guidelines for programmed drinking to maintain performance and minimize the risk of heat casualties. As military personnel increase their fluid intake, their risk of hyponatremia as a result of water overload increases. A potentially life-threatening complication is acute water intoxication. We report the first known death of an Army basic trainee as a result of acute water intoxication. The misinterpretation of his symptoms as those of dehydration and heat injury led to continued efforts at oral hydration until catastrophic cerebral and pulmonary edema developed.

3/113. Fatal child abuse by forced water intoxication.

    BACKGROUND: Although water intoxication leading to brain damage is common in children, fatal child abuse by forced water intoxication is virtually unknown. methods: During the prosecution of the homicide of an abused child by forced water intoxication, we reviewed all similar cases in the united states where the perpetrators were found guilty of homicide. In 3 children punished by forced water intoxication who died, we evaluated: the types of child abuse, clinical presentation, electrolytes, blood gases, autopsy findings, and the fate of the perpetrators. FINDINGS: Three children were forced to drink copious amounts of water (over 6 L). All had seizures, emesis, and coma, presenting to hospitals with hypoxemia (PO2 = 44 /- 8 mm Hg) and hyponatremia (plasma Na = 112 /- 2 mmol/L). Although all showed evidence of extensive physical abuse, the history of forced water intoxication was not revealed to medical personnel, thus none of the 3 children were treated for their hyponatremia. All 3 patients died and at autopsy had cerebral edema and aspiration pneumonia. The perpetrators of all three deaths by forced water intoxication were eventually tried and convicted. INTERPRETATION: Forced water intoxication is a new generally fatal syndrome of child abuse that occurs in children previously subjected to other types of physical abuse. Patients present with coma, hyponatraemia, and hypoxemia of unknown etiology. If health providers were made aware of the association, the hyponatremia is potentially treatable.

4/113. Rapid correction of water intoxication by hypertonic saline and frusemide.

    A case of profound hyponatraemia with severe cerebral dysfunction, induced by excess water intake and exacerbated by smoking, is described. Rapid correction with hypertonic saline infusions and frusemide allowed a negative fluid balance and elevation of serum sodium concentration to be achieved without precipitating acute pulmonary oedema.

5/113. Effect of adjunctive cortisol on serum sodium in a polydipsic hyponatremic schizophrenic patient.

    1. Many polydipsic schizophrenics exhibit enhanced antidiuretic hormone (ADH) activity and thus are hyponatremic and suffer life-threatening water intoxication. Excess cortisol inhibits ADH, while cortisol insufficiency produces impairments in water balance resembling those seen in hyponatremic schizophrenics. Furthermore, hyponatremia normally upregulates cortisol receptors on the neurons which synthesize ADH, which should make them more sensitive to the effects of cortisol. 2. The author treated a hyponatremic schizophrenic, whose water imbalance was unresponsive to standard clinical interventions including clozapine, with a 4-week open trial of 60 mg cortisol daily, followed by a three week taper. 3. Mean serum sodium levels appeared to increase modestly from 114.3 to 118.5 mEq/l while the patient received adjunctive cortisol (P < .06). 4. While a modest effect was seen, the results do not suggest that adjunctive cortisol will reverse hyponatremia, and instead support other data indicating that these patients exhibit a central resistance to glucocorticoid actions.

6/113. Treatment of psychogenic polydipsia: comparison of risperidone and olanzapine, and the effects of an adjunctive angiotensin-II receptor blocking drug (irbesartan).

    OBJECTIVE: Our objective was to determine the outcome of novel strategies in managing a case of severe polydipsia. CLINICAL PICTURE: The patient was a 39-year-old male with a 20-year history of paranoid schizophrenia who, despite only mild residual psychotic symptoms, had been hospitalized for the previous 10 years because of severe polydipsic behaviour complicated by water intoxication. TREATMENT: Novel antipsychotic agents, risperidone and olanzapine, as well as the specific angiotensin-II receptor blocking drug, irbesartan were employed at selected intervals in a study lasting nearly 3 years. A strict behavioural management programme was ongoing, in which diurnal weight change and the number of breaches of weight limits, requiring management in a low-stimulus environment, were documented on a daily basis. Summary measures of diurnal weight change and behavioural intervention were charted against changes in treatment. OUTCOME: Polydipsic behaviour improved on risperidone up to 4 mg daily, but was not sustained. Olanzapine was similarly successful in stabilizing polydipsia, and improvement was achieved with the addition of irbesartan. CONCLUSION: We suggest that the D2-sparing profiles of receptor binding achieved with low-dose risperidone and olanzapine may account for this beneficial effect. The benefit derived with irbesartan implicates the involvement of brain angiotensin systems centrally in helping to regulate drinking behaviour.

7/113. coma and seizures due to severe hyponatremia and water intoxication in an adult with intranasal desmopressin therapy for nocturnal enuresis.

    Desmopressin, a synthetic analogue of the antidiuretic hormone, is an effective medication for primary nocturnal enuresis for both children and adults. Its safety is well established. Although it has a favorable side effect profile, because of its pharmacological effect, intranasal desmopressin can rarely induce water intoxication with profound hyponatremia if given without adequate restriction of water intake. The authors describe an adult patient with water intoxication and severe hyponatremia accompanied by loss of consciousness and seizures after 2-day intranasal administration of desmopressin. The present and the previously reported cases emphasize the need for greater awareness of the development of this serious and potentiallyfatal complication. In addition, to adjust the drug to the lowest required dosage, adequate restriction of water intake is recommended, and serum levels of sodium should be measured periodically to allow for early detection of water intoxication and hyponatremia.

8/113. Fatal water intoxication of an Army trainee during urine drug testing.

    An Army trainee developed acute water intoxication, hyponatremia, pulmonary edema, and fatal cerebral edema. This is the first report of a fatality related to urine drug testing. This resulted from supervised excessive water ingestion in an attempt to induce a sufficient urine specimen for substance abuse testing. To avoid a similar preventable death in the future, we make several recommendations. These include limiting the volume of ingested fluid to eight ounces every 30 to 45 minutes, not to exceed 40 ounces, and providing a relaxed, reassuring environment when obtaining urine specimens for substance abuse detection.

9/113. Perinatal water intoxication due to excessive oral intake during labour.

    The increased body water in pregnant women and the birth-related activation of water-sparing systems contribute to a high risk of perinatal water intoxication if the mother drinks too much water during labour. This study reports on four newborn term infants and one mother presenting with life-threatening symptoms due to hyponatraemia from excessive oral intake during labour. awareness of this diagnosis in the delivery unit is very important, because the clinical picture may mimic that of pre-eclampsia or dehydration. CONCLUSION: Guidelines are proposed to prevent and treat perinatal water intoxication due to excessive oral intake during labour.

10/113. Fatal self-induced water intoxication among schizophrenic inpatients.

    Between 1986 and 1998, a review of 61 records of patients who died before the age of 53 years in eight psychiatric departments whose catchment area had a total population of 559,429 inhabitants revealed that 24 (39.3%) of those patients had a schizophrenic disorder. Of those 24 patients, one (4.17%; 95% CI: 0-21%) died from complications of self-induced water intoxication (SIWIS). Among the 37 remaining patients, two (5.4%; 95% CI: 0-18%) died from complications of SIWIS.
