5-Year analysis of mushroom exposures in California.

OBJECTIVE: To evaluate outcomes following toxic mushroom ingestions. DESIGN: Retrospective data analysis. METHODS: We analyzed American Association of Poison Control Center data for California from 1993 through 1997. RESULTS: A total of 6,317 exposures occurred during the study period. Most (n = 6,229 [99.7%]) were acute exposures, and the rest (0.3%) were chronic; 87.6% (n = 5,536) were unintentional. Most (n = 4,235 [67.0%]) were in children younger than 6 years, and of these, only 6.0% experienced any clinical effects. The most common symptoms in patients aged 6 years and older were vomiting in 588 patients (28.2%), nausea in 307 patients (14.7%), diarrhea in 263 patients (12.6%), and abdominal pain in 221 patients (10.6%). No effects were seen in 3,131 (49.6% of all patients). Major effects were seen in only 17 patients (0.3%). Only 61 patients (1.0%) were admitted to a critical care unit. Death occurred in a 32-year-old adult who ate foraged mushrooms. Of all patients, 1,375 (21.8%) received no therapy or were observed only. CONCLUSIONS: Most mushroom exposures were acute and unintentional and occurred in children younger than 6 years. Major toxic reactions or death was uncommon.

The availability of activated charcoal and ipecac for home use.

Traditionally, ipecac has been used in the home; however, recently attention has focused on pre-hospital activated charcoal (AC) administration. In an effort to assess the availability of AC and ipecac, we conducted a telephone survey. One-hundred and 18 pharmacies were randomly selected from the 59 counties in California to assess availability of AC (liquid or powder) and/or ipecac. Ninety-four (80%) pharmacies participated. Seventy-nine of the pharmacies had ipecac compared to 8 which had AC. Three pharmacies had pre-mixed aqueous AC while 5 had AC in powder formulation. There was no difference between chains and community in AC or ipecac availability. The major limitations of effective GI decontamination are AC availability and rapidity in its administration. Our results identify a significant delay in the administration of AC if a parent was referred to a local pharmacy for home or pre-hospital decontamination. As more toxicologists and poison centers move towards pre-hospital and home AC much education of pharmacists as well as pediatricians and parents is required.

Hypermagnesemia following an acute ingestion of Epsom salt in a patient with normal renal function.

CASE REPORT: Hypermagnesemia is a rare condition that commonly follows excessive therapeutic administration of magnesium sulfate to treat eclampsia of pregnancy. Signs and symptoms of this condition include extreme muscle weakness, loss of deep tendon reflexes, mental status depression, and cardiac dysrhythmias. Clinically significant hypermagnesemia following oral or rectal administration of magnesium containing products in patients with normal renal function is rare. We report a case of hypermagnesemia following massive Epsom salt ingestion that resulted in extreme musculoskeletal weakness and altered mentation.

Ciguatera fish poisoning. A southern California epidemic.

Ciguatera fish poisoning results from the bioconcentration of a variety of toxins produced by marine dinoflagellates. Signs and symptoms vary widely, but it usually presents as gastrointestinal and neurologic complaints beginning shortly after the ingestion of fish containing the toxins. Symptoms may persist for months and sometimes even years. Although cases have been reported throughout the United States, epidemics are most common along tropical and subtropical coasts and usually involve the ingestion of large carnivorous fish. We review the literature and report the first epidemic of 25 cases of ciguatera fish poisoning presenting to area hospitals in Southern California that were successfully tracked by the Department of Health Services and isolated to fish caught off the coast of Baja California, Mexico.

Comparison of pediatric poisoning hazards: an analysis of 3.8 million exposure incidents. A report from the American Association of Poison Control Centers.

This analysis of life-threatening and fatal pediatric poisonings was conducted to aid poison prevention educational efforts, guide product reformulations and aversive agent use, reassess over-the-counter status for selected pharmaceuticals, and identify research areas for clinical advances in the treatment of pediatric poisonings. A hazard factor was devised to assess more objectively the pediatric poisoning hazard posed by pharmaceutical and nonpharmaceutical products. By considering the frequency and extent of injury following actual exposures, the hazard factor reflects more than the acute toxicity of individual ingredients and is also influenced by such variables as packaging, accessibility, availability (as a reflection of marketing), formulations, and closure types. Of the 3,810,405 exposures involving children younger than 6 years of age reported to poison centers in 1985 through 1989, 2117 patients experienced a major outcome (life-threatening effect or residual disability) and an additional 111 fatalities occurred. The three most commonly implicated substance categories, accounting for 30.4% of reported exposures, include cosmetics and personal care products, cleaning substances, and plants. All had low hazard factors, with significant hazards being limited to a small number of products identified herein. Thus this analysis of hazard factors demonstrates that frequent exposure does not imply toxicity. Iron supplements were the single most frequent cause of pediatric unintentional ingestion fatalities, accounting for 30.2% of reported pediatric pharmaceutical unintentional ingestion fatalities reported over an 8-year period. Antidepressants, cardiovascular medications, and methyl salicylate follow in frequency of pediatric pharmaceutical deaths. Hydrocarbons (including five lamp oil deaths) and pesticides were each implicated in 12 pediatric ingestion fatalities during the 8-year period.(ABSTRACT TRUNCATED AT 250 WORDS)

Prehospital use of activated charcoal: a pilot study.

Activated charcoal (AC) is most effective when administered soon after the ingestion of certain substances. Delays are recognized to occur at times in the administration of AC after arrival of poisoned patients in the emergency department (ED). In addition, it has been recognized that these delays may be avoided if AC administration is begun in selected patients by paramedics while en route to the ED. We present a pilot study evaluating the administration of AC to poisoned patients in the ambulance prior to arrival in the ED. We performed a retrospective review of Emergency Medical System (EMS) run sheets and ED records of poisoned patients during a 6-month period from two area hospitals. Cases were identified that met criteria for the prehospital administration of AC. Cases were divided into two groups: those who received prehospital AC, and those who did not. Groups were compared for ambulance transport time, time from first paramedic contact to AC administration, and whether AC was tolerated by the patient. A total of 14 patients received prehospital AC (group 1). This group was compared to 22 cases that would have qualified under County protocol to receive prehospital AC, but for whatever reason did not (group 2). Group 2 patients all received AC after arriving in the ED. Average ambulance transport times did not statistically differ among groups. The average time from first encounter with paramedics to administration of AC was 5.0 minutes when AC administration was given in the ambulance as compared to 51.4 minutes when delayed until arrival in the ED. Tolerance was similar among the groups. The time to initiate AC administration may be significantly shortened when begun by prehospital personnel. All EMS should consider including AC in protocols addressing the prehospital management of certain poisoned patients.
