Analysis of initial requests for information of non-exposure related topics at a regional poison center.

Regional poison centers have experienced continued growth for drug exposure related information. At our regional poison center, because of increased requests for information which is non-drug or non-exposure related, we chose to select a sampling of telephone inquiries to document such topics. We wished to document the demographics of the caller, the major category of information requested, the triage of the call, the pertinent history and quote of the call, and the interpretation of the call by our poison information specialists. Of the 164 calls sampled, the majority of the calls were initiated from a home site (89%) with an adult (79.3%) female (62.2%) asking for the information. Of the ten major categories of non-drug or non-exposure related issues, general medical information was most often requested (65.2%). The poison specialists' triage of calls required no follow-up in 72% of calls, however 5.5% of the callers were directed to an emergency department, with 12.2% directed to another health agency for additional information. As funding for all medical and health related resources becomes limited, it is important the public be made aware of its own utilization of public resources. This will enable a basis for obtaining financial support outside of drug-related arenas, will return a positive statement to the public that not only do poison centers consult on exposures; but also that the dollars spent are utilized in an extremely widened brevity of information for the publics consumption. This information will support enhanced budget requests for personnel education and training in areas of non-drug or non-exposure related issues.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of fluid volume on syrup of ipecac emesis time.

Large volumes of fluid have been recommended to aid rapid ipecac-induced emesis, however, large volume intake may also have deleterious effects. We prospectively studied 121 children treated at home by a regional poison center to determine if a relationship existed between fluid volume and time to emesis. These children were treated in the usual manner except that parents were asked to measure the volume of fluid given and to note the time that fluid was given and the time of first emesis. The time ranged from 6 to 58 minutes (mean 20.6) with two who failed to respond and the volume ranged from 0 to 28 ounces (mean 6.7 ounces). In children who respond to ipecac, there is no significant relationship between the amount of fluid given and the time until emesis. We conclude that the traditional recommendation of forcing fluid with syrup of ipecac does not hasten emesis in children.

Home parenteral nutrition in a child with Menetrier disease.

A 4-year-old boy is described with abdominal pain, emesis, weight loss, hypoproteinemia and edema. The diagnosis of Menetrier disease was made based on radiographic studies, gastroscopy and gastric biopsy. There was little response to medical treatment and enteral feedings were poorly tolerated for many weeks. Although Menetrier disease in children has a benign and transient course, we found the use of home hyperalimentation significantly shortened the length of hospitalization and provided adequate nutritional support until the gastric lesions began to resolve.

The referral of patients from freestanding emergency centers to a hospital emergency department.

This retrospective study is a review of patients referred from a network of eight freestanding emergency centers FECs to a hospital emergency department during January and February 1984. During that time, 17,387 patients were seen at the FECs. Sixty-three (0.36%) of these patients were referred to the base hospital, of which 28 (44%) were admitted and six (9.5%) were admitted to a critical care unit. Four of the six critical care admissions arrived by ambulance. One was unstable and required cardioversion in the ED. Of the patients discharged from the hospital 70% were satisfied with FEC and 97% with hospital treatment. Of admitted patients, 89% were satisfied with FEC and 100% were satisfied with hospital treatment. For a similar illness in the future, 23% of all patients would return to a FEC, 28% would go to a private practitioner, and 48% would go directly to a hospital.

A pictorial portrayal of poisoning possibilities: a public awareness approach.

Areas of a high density university housing cooperative were randomly photographed following reports of decreased child supervision and increased potential for childhood poisoning and injury. A slide show was developed using these actual settings which revealed potential exposure to multiple toxic chemicals. This show was presented to the residents and demonstrated the high risk situations. Residents discovered that toxic chemicals were present in their own living environment, that many routes of exposure were possible and the high susceptibility of children during unsupervised play. As a result of this educational program, a poison prevention policy was approved with subsequent visible improvement in the community awareness and environment. This pictorial approach is a useful method for educating residents of a high density housing development about potential poisonings in their home environment and may be applied to other similar settings.

Membrane changes in a single photoreceptor cause associative learning in Hermissenda.

Single type B photoreceptors in intact, restrained Hermissenda were impaled with a microelectrode and exposed to either paired or unpaired presentations of light and depolarizing current to simulate natural stimulus effects during conditioning with light and rotation. Paired, but not unpaired, stimulus presentations produced cumulative depolarization and increased input resistance in type B cells. These membrane changes are similar to those observed after pairings of light and rotation are administered to either intact animals or isolated nervous systems or when light is paired with electrical stimulation of the vestibular system in isolated nervous systems. One and two days after treatment, pairing- and light-specific suppression of phototactic behavior was observed in recovered animals. These findings indicate that the membrane changes of type B cells produced by pairing light with current injections cause acquisition of the learned behavior.

Diltiazem overdose: case report and review.

We present a case of diltiazem overdose in which the patient ingested 4.2 grams in an apparent suicide attempt. He arrived in the emergency department two hours postingestion with a blood pressure of 60/40 torr and a heart rate of 62 beats/min in a junctional rhythm. Intervention included activated charcoal, gastric lavage, intravenous fluids, calcium (both chloride and gluconate), dopamine, and atropine with improvement in vital signs. Diltiazem levels were obtained and half-life calculated. This ingestion is one of the largest reported in the literature and is remarkable in that the patient recovered without pacing or other extraordinary measures. All eight previously published cases of diltiazem overdose, including all unpublished reports to the manufacturer, are reviewed and their management strategies examined. Successful treatment in which recovery has occurred in less than 48 hours, includes pressors, calcium, glucagon, pacing, and charcoal hemoperfusion. A strategy for emergency physicians to use when approaching this problem is suggested from the review.
