Severe accidental colchicine poisoning by the autumn crocus: A case of successful treatment

AbstractBackgroundThe common garden plant autumn crocus contains colchicine and its derivatives. Colchicine poisoning causes abdominal cramps and diarrhea within hours. Several days later, multiorgan failure, pancytopenia, and cardiovascular collapse occur.1,2 Severe colchicine poisoning is associated with high mortality.Case reportA 63-year-old woman who accidentally ingested an autumn crocus, which contained ∼0.38 mg colchicine, had severe vomiting and was taken to an emergency center. She presented with symptoms of gastroenterocolitis within 1 hour of ingestion, and bone marrow hypoplasia with pancytopenia developed on the 3rd day after ingestion. We continued administration of granulocyte colony-stimulating factor (300 μg) for 5 days until we confirmed that the patient's white blood cell count was increasing. Also, there was focal and segmental intestinal ischemia and some cakes of charcoal remained in the intestinal tract. Therefore, we presumed that nonocclusive mesenteric ischemia was caused by hypotension with severe dehydration, although pseudo-obstruction due to the activated charcoal may have been a contributing factor. We were able to promptly intervene to treat paralytic ileus and gastrointestinal edema before anticipated worsening of abdominal compartment syndrome, by conducting open peritoneal drainage. Despite severe poisoning, our patient survived with intensive care. Conclusion: Colchicine intoxication may lead to a sudden and extreme critical course. Therefore, as there is no means to predict prognosis from initial severity of symptoms at onset, we suggest that all patients suspected of colchicine intoxication should be managed in hospital with continuous vital sign monitoring and frequent laboratory testing for at least a few days after ingestion

Successful treatment of severe accidental hypothermia with cardiac arrest for a long time using cardiopulmonary bypass - report of a case

Accidental hypothermia is defined as an unintentional decrease in body temperature to below 35°C, and cases in which temperatures drop below 28°C are considered severe and have a high mortality rate. This study presents the case of a 57-year-old man discovered drifting at sea who was admitted to our hospital suffering from cardiac arrest. Upon admittance, an electrocardiogram indicated asystole, and the patient's temperature was 22°C. Thirty minutes of standard CPR and external rewarming were ineffective in raising his temperature. However, although he had been in cardiac arrest for nearly 2 h, it was decided to continue resuscitation, and a cardiopulmonary bypass (CPB) was initiated. CPB was successful in gradually rewarming the patient and restoring spontaneous circulation. After approximately 1 month of rehabilitation, the patient was subsequently discharged, displaying no neurological deficits. The successful recovery in this case suggests that CPB can be considered a useful way to treat severe hypothermia, particularly in those suffering from cardiac arrest

Acquisition of a Transposon Encoding Extended-Spectrum β-Lactamase SHV-12 by Pseudomonas aeruginosa Isolates during the Clinical Course of a Burn Patient▿

Three of seven clonally related Pseudomonas aeruginosa strains isolated from a burn patient produced the extended-spectrum β-lactamase (ESBL) SHV-12. Its gene was flanked by two IS26 elements with a large transposon (>24 kb). The transposon also contained at least five IS26 elements and a gene encoding the amikacin resistance determinant aminoglycoside 6′-N-acetyltransferase type Ib [aac(6′)-Ib]. It was inserted into the gene PA5317 in the P. aeruginosa chromosome
