A 45-year-old white man ingested approximately two cups of boric acid crystals dissolved in water in a suicide attempt. Nausea, vomiting, greenish diarrhea, and dehydration occurred shortly thereafter. Two days later, he presented to the hospital with hypotension, metabolic acidosis, oliguric renal failure, a generalized erythematous rash, and several superficial skin abrasions. His condition failed to improve despite intravenous fluids and vasopressors. He later developed atrial fibrillation with a rapid ventricular response and could not be converted to a sinus rhythm. This rhythm deteriorated to electromechanical dissociation, and the patient died 17 hours after admission. The urine and whole blood boric acid concentrations approximately 52 hours after ingestion were 160 and 42 mg/dL, respectively. These results are equivalent to urine and blood boron concentrations of 28 and 7 mg/dL, respectively. A postmortem urine boron concentration was 29.4 mg/dL. The autopsy report listed boron toxicity as the cause of death. This is the only adult reported to die from acute boric acid ingestion in recent years and may be atypical since the patient was untreated for 3 days and presented with dehydration and renal function impairment. This case suggests that lack of adequate urine flow and dehydration increases the risk of boron toxicity.

Poisoning is a significant problem in the elderly. The majority of poisonings in older people are unintentional and may result from dementia and confusion, improper use of the product, improper storage or mistaken identities. Depression is also common in the elderly and suicide attempts are more likely to be successful in this age group. The elderly patient's recuperative abilities may be inadequate as a result of numerous factors including impaired hepatic or renal function as well as chronic disease processes. General management of poisoning in the elderly parallels management of younger adults, but it is especially important to ascertain underlying medical conditions and concurrent medications. In most poisonings, activated charcoal and cathartic are sufficient. Haemodialysis or haemoperfusion may be required at lower plasma drug concentrations in elderly patients. While the specific indications for antidotes are the same for all age groups, dosage alterations and precautions may need to be considered in the elderly. Drugs most often implicated in poisonings in the elderly include psychotherapeutic drugs, cardiovascular drugs, analgesics and anti-inflammatory drugs, oral hypoglycaemics and theophylline. Cardiovascular and neurological toxicities occur with overdoses of neuroleptic drugs and, more frequently and severely, with cyclic antidepressants. Patients with pre-existing cardiovascular disease are at particular risk of worsening ischaemic heart disease and congestive heart failure. Benzodiazepines only appear to produce significant toxicity during long term administration or in combination with other CNS depressants. Digoxin can cause both chronic and acute intoxication, most seriously cardiac toxicity including severe ventricular arrhythmias, second or third degree heart block or severe refractory hyperkalaemia. Immune Fab antibody is indicated for the management of digoxin toxicity, although patients dependent on the inotropic effect of digoxin may develop heart failure after digoxin Fab antibody administration. Nitrates can cause toxicity including headache, vomiting, hypotension and tachycardia from excessive sublingual, transdermal or intravenous doses. Conduction disturbances and hypotension occur with overdoses of antihypertensive drugs; these effects are mild with angiotensin converting enzyme (ACE) inhibitors, occasionally severe with beta-blockers and of significant concern with calcium channel antagonists. The elderly commonly use aspirin and other salicylates, are more likely to develop chronic intoxications to these agents, and are more susceptible to severe complications such as pulmonary oedema. Salicylate poisoning, recognition of which is often delayed, should be considered in elderly patients with neurological abnormalities or breathing difficulties, especially in the setting of acid-base abnormalities. The clinical effects of NSAID overdose are mild and usually involve the central nervous system and gastrointestinal tract.(ABSTRACT TRUNCATED AT 400 WORDS)

Acute salicylate poisoning with enteric-coated aspirin may result from accidental ingestion, a suicide attempt, or a complication of long-term therapy. Because absorption of enteric-coated aspirin is delayed, use of the Done nomogram to determine toxicity may lead to underestimating the severity of the poisoning. Treatment options include induction of emesis or diuresis, gastric lavage, administration of activated charcoal, and surgery.

A 23 year old male developed abdominal pain, diarrhoea, and vomiting several hours after poisoning with acute triphenyltin intoxication in a suicide attempt. Severe ataxia, dysmetria, nystagmus, and blurring of vision soon supervened. Disturbance of consciousness and confusion developed 12 days later and lasted for two months. A delayed sensorimotor polyneuropathy was shown by electrophysiological studies to be due to axonal degeneration and demyelination. The neuropathy rapidly recovered after consciousness was regained.

We experienced a case of a 44 year old man who had ingested potassium bromate solution for suicide attempt. Soon after the ingestion, nausea, vomiting, abdominal pain and diarrhea developed in him. Several hours later, he began to complain of auditory disturbance and, in addition, anuric acute renal failure occurred. Direct hemoperfusion and hemodialysis was performed on the patient for the treatment purpose. Five weeks later, he was released from hemodialysis procedure. Gradually, on the other hand, progressing anemia was observed until 90th hospital day, which slowly improved thereafter. Further, pruritus, lower leg pain, headache, tinnitus and loss of sense of taste, etc. were observed in the clinical course. Renal biopsy was performed on the 119th hospital day and the specimen showed the regenerative stage of acute tubular necrosis. In our case, acute renal failure was reversible and, many other clinical manifestations were observed. However slight anemia and irreversible severe auditory disturbance remained unimproved.

We hypothesized that high school students who experienced prior maltreatment would be more likely than their peers to report health risk behaviors and suicide attempts. Before the establishment of a high school-based clinic, an anonymous needs assessment survey was completed by 600 adolescents (grades 9 to 12). Sociodemographic information was obtained and questions were asked about physical and sexual abuse, health-related behaviors and habits, and suicide attempts. Thirteen percent of the adolescents had been maltreated: 5.2% reported prior physical abuse, 5.4% sexual abuse, and 2.7% both physical and sexual abuse. Multivariate statistical techniques were used to clarify how previous abuse was related to adolescent risk-taking behaviors and suicide. Students with a history of physical abuse were three times more likely than non-abused peers to drink alcohol and smoke cigarettes, almost twice as likely to use illicit drugs, six times more likely to self-induce vomiting, and five times more likely to attempt suicide. A student with a history of prior sexual abuse had a three and one-half times greater chance of being sexually active and was more than three times more likely to attempt suicide. These data on a nonclinical, nondeviant population of adolescents indicate that physical or sexual abuse in childhood may have a significant impact on adolescent health risk behaviors and suicide attempts.

Patients who have bulimia nervosa and are overweight have received little attention in the medical literature. The authors identified 25 patients who weighed greater than or equal to 130% of their ideal body weight out of a series of 591 patients with bulimia nervosa. This subgroup was contrasted with a sample of 25 patients with bulimia nervosa who were 90% to 110% of their ideal body weight. Members of the overweight bulimia nervosa group were binge-eating and vomiting less frequently than the comparison group but were more likely to be abusing laxatives, and to report a history of self-injurious behavior and suicide attempt(s). Both groups reported frequent binge-eating.

The literature was reviewed for cases of cutaneous pigmentation induced by rifampicin overdosage. 29 examples have been described, in which 2 general groups of individuals were observed. The first consisted of older individuals (average age 27.1 years) who attempted suicide. A prior history of suicide attempts, depression and substance abuse was a predominant factor in these patients. The second group included generally younger patients (average age 2.9 years) in whom misformulation of rifampicin preparations for treatment of Haemophilus influenzae Type B resulted in bright reddish-orange discoloration to the skin. The time to clinical appearance of skin discoloration was approximately 2.2 hours after administration. Periorbital or facial oedema occurred in 72.4% of the patients, pruritus in 62.1% and either nausea, vomiting or diffuse abdominal tenderness in 51.7%. Limited laboratory data are available but these indicate that all patients had elevated levels of total bilirubin. Histological examination in selected individuals revealed rifampicin crystal deposits in the nasopharynx, gastrointestinal tract and lining of the aorta. In adults, it appears that a dose of at least 14 g of rifampicin is necessary before cardiovascular-pulmonary arrest occurs. Other than general supportive measures, very few methods are described in the literature for the treatment of acute intoxications with this drug. A differential diagnosis of other causes of reddish-orange pigmentation is discussed, together with clinical information to differentiate these cases from toxic rifampicin ingestion.

Nitulamide (ANANDRON (R] is an antiandrogen used as an adjuvant therapy in the treatment of advanced prostatic cancer. The effects of ingestion of high doses of nitulamide has not been so far reported. A 79 years old man was admitted 2 hours after the ingestion of 13 g of nitulamide (170 mg/kg or 43 times the therapeutic dose), in a suicide attempt. He was receiving nitulamide 300 mg/day for two weeks. On admission, he underwent immediately gastric lavage, followed by administration of oral activated charcoal and received an intravenous infusion of glucose in balanced salt solution. During the first 12 hours, the patient presented with moderate vomiting and diarrhoea. There was no change in the following parameters: blood cell count, plasma electrolytes, serum transaminases and serum bilirubin, arterial blood gases, plasma cortisol value, as compared to the pre-treatment values. Chest X ray was unchanged. Plasma concentrations were measured 2 hours, 3 hours, 12 hours, 24 hours, 48 hours and 72 hours after ingestion. The initial level reached 6 times the normal therapeutic range, then fell to 3.5 times at the 72th hour. The patient recovered rapidly and was discharged on the 4th day. Biologic parameters were controlled on 4th, 9th, 30th day and remained unchanged. Treatment was started again on the 30th day with nitulamide 150 mg/day. We did not notice any side effect previously described in daily administration of nitulamide: anemia, rise in serum transaminases, interstitial pneumopathy.

A 40-year-old woman with a history of alcohol abuse, drug-related suicide attempts, and depression presented with a flu-like illness, vomiting, and changes in mentation. On admission, therapeutic blood levels of salicylates, trazadone, and acetaminophen were found. A tentative diagnosis of a psychotic crisis with possible superimposed drug overdose was made. The etiology of the patient's acute encephalopathy remained unclear until a plasma ammonia and liver biopsy established the diagnosis of Reye's syndrome. The patient was given supportive therapy and recovered completely.
