Predictors of outcome in children with hydrocarbon poisoning receiving intensive care.

The retrospective study included 48 children between 8.5 months--10 years, admitted to the PICU of an urban, tertiary care, teaching hospital in northern India from January 1995 to December 2001. Eighteen (38%) patients were hypoxemic on arrival, of which 8 (45%) required mechanical ventilation. Compared to the non-hypoxemic children, the hypoxemic patients were more likely to have received gastric lavage before arrival to our center (Odds Ratio 23.2, 95% CI 2.4 - 560.7) and had higher frequency of severe respiratory distress and leucocytosis (Odds Ratio 8.0, 95% CI 1.79 -38.6). On multiple regression analysis, we could not identify any particular variable that could predict hypoxemia. Secondary pneumonia developed in 16 (33.3%), with the duration of PICU stay being longer in these patients as against those who did not (144 hours vs 72 hours, p <0.05). Two (4.2%) children died and one suffered hypoxic sequelae. Prior lavage, hypoxemia at admission, need for ventilation, secondary sepsis and ventilator related complications were associated with poor outcome.

[Thorn apple poisoning].

A 20-year-old man presented with signs of thornapple intoxication: restlessness, disorientation, hallucinations, euphoria, and furthermore dry and red skin and symmetrical dilation of the pupils. Thornapple intoxication mimics atropine intoxication. Thorn apples (Datura stramonium) are seemingly becoming popular as a hallucinogenic drug. When the symptoms are mild gastric lavage leaving active charcoal in the stomach afterwards will suffice. In case of severe symptoms treatment with physostigmine is indicated.

Slow-release verapamil poisoning. Use of polyethylene glycol whole-bowel lavage and high-dose calcium.

OBJECTIVE: To present three cases of slow-release verapamil poisoning that demonstrate the prolonged absorption of the drug and the role of polyethylene glycol and high-dose calcium in management. CLINICAL FEATURES: Three patients with slow-release verapamil poisoning are presented. An 18-year-old woman took 2.3 g and developed hypotension and bradyarrhythmias 18 hours after ingestion, despite gastric lavage and administration of charcoal at three hours. A 23-year-old woman took 4.8 g and presented two hours later clinically unaffected. A 44-year-old woman presented 24 hours after taking 15-20 g. She had a systolic blood pressure of 50 mmHg, no measurable diastolic blood pressure and bradyarrhythmias. INTERVENTION AND OUTCOME: Case 1 responded to administration of 30 g of calcium and fluids intravenously. Case 2 was given polyethylene glycol on admission which resulted in passage of a tablet bezoar and no toxicity. Polyethylene glycol was ineffective in Case 3. She responded initially to high doses of calcium and other treatments, but subsequently died of hypotension and cardiac conduction block 39 hours after the overdose. CONCLUSION: The severity of poisoning with slow-release verapamil warrants aggressive pre-emptive treatment. Polyethylene glycol should be used routinely irrespective of the clinical state. High doses of calcium may be required to treat conduction block and hypotension.

A fatal case of apparent water hemlock poisoning.

A 14-y-o North American native boy died 20 h after ingesting "wild carrot". He was gathering edible plants with his family on Canadian Thanksgiving. A sample of the plant he ingested couldn't be positively identified but it contained cicutoxin on chromatography. Bioassay caused death in mice which demonstrated clinical signs similar to water hemlock (Cicuta maculata) poisonings. Cicutoxin could not be demonstrated in postmortem tissue or gastric lavage. The boy's clinical signs and laboratory tests were consistent with other reported cases of this poisoning.

[The characteristics of the radiation lesion in exposure of the anterior abdomen in dogs and the effect of modifying factors].

A comparative study was made of the effect of gamma/neutron and X-radiation on the forepart of dog abdomen. The RBE coefficient was found to depend upon body mass and to range from 1.3 to 1.5. The exclusion of the sympathetic nervous system before irradiation was shown to aggravate the clinical condition and to increase the death rate. On the contrary, the exclusion of the parasympathetic nervous system before irradiation and gastric lavage after irradiation improved the clinical picture of radiation sickness and increased the radioresistance of dogs.

Adverse reactions and interactions with theophylline.

Despite the trend towards newer therapeutic agents, theophylline continues to play a major role in the treatment of reversible airway obstruction. Clinical use of the drug is complicated by a relatively narrow therapeutic range and a large pharmacokinetic variability between patients. Generally, however, theophylline toxicity is foreseeable and preventable. Most cases can be attributed to either inadvertent or intentional overdosing of the drug. Age, disease state and drug interactions are other factors which may contribute to its toxicity. Nausea, vomiting and tachycardia are common signs of mild theophylline toxicity; seizures, ventricular arrhythmias and hypotension are life-threatening manifestations of severe toxicity which may respond poorly to standard therapy. Although serum theophylline concentration correlates with toxicity in a general fashion, life-threatening adverse reactions are not readily predictable from the drug concentration alone. Treatment of theophylline toxicity primarily involves supportive care along with gastric lavage and administration of activated charcoal to facilitate drug removal. The early use of haemoperfusion may be life-saving in cases of severe toxicity.

[Acute klofelin poisoning].

Clofelin poisoning induced accidentally, criminally or suicidally was treated and followed up in 862 adults and 96 children admitted to specialized centers. The most common clinical symptoms were bradycardia and mental confusion due to SNC toxic affection. Specific cardiotoxic effect of the drug was not registered. Therapeutic measures included detoxication (gastric lavage, forced diuresis, ect.) and pharmacological correction of cardiac rhythm with atropine and metacine.

Esophageal food impaction: description of a new method for bolus removal.

Food impaction in the esophagus is a relatively common problem seen in an emergency room setting. Traditional methods of extraction have been dangerous, time-consuming, or laborious. We review available therapeutic modalities for bolus extraction, and describe a new method using a modified 34F gastric lavage tube connected to a 120-cc aspiration syringe. This method of food removal has proven safe and effective and is readily utilized in the outpatient setting.

[Role and potentials of the pathologist in modern clinical gastroenterology. In memory of Prof. Géza Hetényi].

In the course of memorial lecture the author commemorates Professor Géza Hetényi. His synthetizering role is stressed, analysing the professor's views on the clinical and theoretical medicine, on the medical practice and teaching in the medicine. Author performs it from the points of view of practising pathologist who considered the clinical pathology as the most important. After these introductory thoughts the role of pathologist is outlined in the gastroenterological diagnostics. Before the introduction of modern fiberoptic endoscopy, the pathologist met with some forms of the gastroenterological diseases at most during the processing work of surgically removed specimens or even more in the autopsy room, but in the latter cases only their end stage could be demonstrated. The introduction of so-called blind exfoliative cytology by the gastric lavage was a great leap forward. Advanced gastric carcinoma were detected mostly by this method but some early gastric cancer could be also discovered occasionally. The more and more wide-spread use of modern fiberpotic endoscopy was of decisive importance because by this way the aimed forceps biopsy could be performed completed with a new form of gastric cytology, with abrasive smears. The specificity and sensitivity of the latter method achieves or surpasses the 90%. Nowadays, not only the stomach carcinomas but their possible precancerous conditions and changes as chronic gastritis can be diagnosed on morphological basis. The history of different gastritis classifications is also surveyed emphasised author's own pathogenetic conceptions which can be included well in our now accepted modern Sydney-classification.(ABSTRACT TRUNCATED AT 250 WORDS)

Gastrointestinal decontamination after poisoning. Where is the science?

The approach to the use of gastrointestinal decontamination procedures in the treatment of ingested toxins has changed in recent years. Many toxicologists and physicians have taken strong positions either for or against the use of emesis, gastric lavage, activated charcoal, or other procedures. What is the scientific basis for these positions? This article reviews and comments on the published studies comparing the effectiveness of these widely used procedures.

[Poisoning with cholinesterase inhibitors].

A 32-year-old woman who had ingested 300 ml of a potent cholinesterase inhibitor insecticide (Fonofos) with suicidal intent became progressively comatose and finally suffered respiratory arrest. Tracheal intubation, mechanical ventilation, vigorous gastric lavage and intravenous administration of atropine and obidoxime brought about complete clinical recovery within 24 hours of ingestion of this potentially fatal dose of Fonofos.

[The intoxication with cyclizin in infancy and adult age (Experiences of a contamination-information-central office) (author's transl)].

Epidemiological, clinical and therapeutic aspects obtained from 38 cases of intoxication with the antiemetic drug "cyclizine" in children and adults are discussed. The relative frequency of accidentally or purposely performed overdosage shows a decreasing tendency. The introduction of regulations after the prescription of cyclizine compounds, leaving a limited dose available without prescription and the introduction of a safety package to prohibit misuse by children are reported in their relationship with the epidemiologic data. A toxic dose of 5 mg/kg body weight, a minimal lethal dose (MLD) of about 80 mg/kg are evaluated and compared with previous published data. Differences of age in the development of the clinical picture of the cyclizine-intoxication with a disposition for the evolvement of convulsions in children compared to the total lack of convulsions in adults have to be pointed out. The management of overdoses follows general principles of treatment like gastric lavage, supporting care and includes the specific treatment with the antidote "physostigmin-salicylate", which causes a shortening of the time of recovery.

Decontamination.

Decontamination is the removal or reduction of chemical, biologic, or radiologic agents from the patient's skin, mucosa, lungs, and gastrointestinal tract. Decontamination is an important step in decreasing the clinical effects of the agent on the patient, as well as protecting coworkers from exposure. For most agents and the vast majority of scenarios, the removal of clothing and a simple 5- to 6-minute shower with soap and water is sufficient to eliminate the risks to the patient and hospital staff. In rare circumstances, additional steps in decontamination including gastric lavage, broncho-alveolar lavage, surgical removal of wound foreign bodies, and administration of activated charcoal, polyethylene glycol electrolyte solution, and radioisotope binding agents, may be necessary.

Successful management of severe paraquat poisoning.

A case of paraquat poisoning was successfully treated which would have been considered lethal according to a reported prognostic index. Main features in the treatment were removal of paraquat by gastric lavage, forced diuresis, hemodialysis, and charcoal hemoperfusion. Early ventilation with low FIo2 and with positive end-expiratory pressure (PEEP) were also utilized.

Assessment and treatment of acetaminophen overdose.

The assessment and treatment of acute acetaminophen toxicity are reviewed, and several unresolved issues are discussed. The drug most commonly involved in analgesic ingestions, as a single agent or in combination, is acetaminophen. Hepatotoxicity, the major manifestation of acetaminophen ingestion, is believed to result from the accumulation of a toxic metabolite, N-acetylimidoquinone. The clinical features of acetaminophen toxicity are divided into four stages ranging from minor symptoms, such as gastrointestinal irritation, to coma and death. The most reliable method for assessing the severity of acetaminophen ingestion is comparison of serum acetaminophen concentrations with the Rumack-Matthew nomogram. Delaying the start of antidotal therapy for more than 10 hours after the ingestion increases the risk of toxicity; no benefit is observed when antidotal therapy is initiated more than 24 hours after ingestion. Acetaminophen is often marked in combination with other drugs; a detailed patient history and a urine toxicology screen help determine whether multiple toxic ingestions have occurred. The roles of ipecac, gastric lavage, and activated charcoal in therapy are controversial. The mainstay of treatment for acetaminophen intoxication is a 17-dose course of acetylcysteine.
