There is limited information on potentially adverse lisinopril ingestions reported to poison control centers. Using adult lisinopril ingestions reported to Texas poison control centers during 1998-2005, the proportion of cases involving serious outcomes was determined for selected variables and evaluated for statistical significance by calculating the rate ratio (RR) and 95% confidence interval (CI). Of 468 cases identified, 43 (9%) involved serious outcomes. ⋯ Thus, serious outcomes were significantly more likely to occur with a maximum dose >80 mg (RR 5.69, CI 2.43-13.33) or, if the dose was unknown, > or =3 tablets (RR 9.57, CI 2.39-54.97), where the circumstances of the exposures involved self-harm or malicious intent (RR 6.96, CI 3.65-13.31), or the patient was already at or en route to a health care facility when the poison control center was contacted (RR 7.33, CI 3.09-17.85) or referred to a health care facility by the poison control center (RR 23.76, CI 10.62-55.67). The management of patients with severe outcomes was more likely to involve health care facilities. Such information is useful for creating of triage guidelines for the management of adult lisinopril ingestions.

Aluminium phosphide is a solid fumigant pesticide and has systemic toxicity due to liberation of phosphine gas. We report a case of aluminium phosphide poisoning with systemic toxicity in a 16-year-old patient who developed previously undocumented complication of subendocardial infarction, with characteristic electrocardiographic changes reverting back to normal after a period of 10 weeks, even though the patient had clinical recovery much earlier.

Lisinopril is not recommended for use by young children. This study attempted to identify factors associated with serious outcomes in pediatric lisinopril ingestions. Cases for this study were lisinopril ingestions by children age < or =5 years reported to Texas poison control centers during 1998-2005. ⋯ Higher serious outcome rates were found with a maximum dose of >4 mg/kg (RR: 2.54, CI: 0.05-25.62), or >80 mg (RR: 7.85; CI: 1.73-29.29), or five or more tablets (RR: 8.18; CI: 2.73-22.54), or the patient was already at or en route to a health care facility when the poison control center was contacted (RR: 13.93; CI: 3.68-77.78), or referred to a health care facility by the poison control center (RR: 33.49; CI: 9.04-194.94). The management of patients with severe outcomes was more likely to involve health care facilities. This information is useful for drafting triage guidelines for the management of pediatric lisinopril ingestions.

Between 1993 and 2004, patients with antidepressant poisoning admitted to an emergency department (ED) were analysed retrospectively with regard to demographics, clinical findings and treatment attempts. Age, gender, suicide attempts, classification of antidepressants, Glasgow Coma Scale (GCS) score, ECG findings, need for endotracheal intubation, follow-up period and Antidepressant Overdose Risk Assessment (ADORA) criteria were analysed by SPSS software. A total of 356 antidepressant poisoning cases were evaluated. ⋯ Patients with TCA ingestion had a longer observation time in the ED, abnormal ECG findings, abnormal physical examination findings and more ADORA criteria, than patients who ingested selective serotonin re-uptake inhibitors (SSRI) (P = 0.008, P = 0.008, P < 0.001, P < 0.001). It was found that the patients who ingested TCA (P = 0.001), poisoned with amitriptyline (P = 0.001), patients with GCS scores of 8 and less (P = 0.001), patients with two or more ADORA criteria (P = 0.001), with seizures (P = 0.001), with abnormal ECG (P = 0.012), and patients with a history of two or more suicide attempts were intubated more frequently. Suicide attempts, classification of the antidepressant, ECG findings, seizure, GCS score and number of detected ADORA criteria affect the need for intubation in patients with antidepressant poisoning.

Carbon monoxide (CO) poisoning is the leading cause of death from intoxication. In CO poisoning, it is important to know if there are any symptoms regarding myocardial damage, which are usually unobserved as a result of hypoxia. This study was planned to assess myocardial damage in young healthy patients with CO poisoning. ⋯ Myocardial damage due to CO poisoning should not be ignored. If patients are at risk in terms of myocardial damage, further studies, such as ECHO and scintigraphy are needed to determine myocardial damage resulting from CO poisoning. However, in the young adults of the risk group, if the baseline ECG and serial cardiac biomarkers are normal, further studies such as ECHO and scintigraphy, considering the length of exposure and the severity of poisoning, may not be necessary for the evaluation of myocardial damage due to CO poisoning.
