Patient's death as a result of mistakenly injection of pancuronium.

Pancuronium is a typical non-depolarizing, curare-mimetic, very potent muscle relaxant. Besides application in anesthesiology and intensive care, it is used in execution as a part of lethal injection. In medico-legal practice, there are cases of using this substance in order to commit suicide or to deprive other people of their lives. Accidental pancuronium intoxications are very rare. The authors present such case ended in sudden death of hospitalized woman after mistakenly injection of the drug. 57-year-old female alcoholic was admitted to the Acute Poisoning Centre after ethylene glycol ingestion. During the fifth day of treatment the nurse by mistake, instead of furosemide, intravenously administered her pancuronium. Sudden respiratory and circulatory arrest occurred, so she was intubated and resuscitation with artificial ventilation were undertaken, however within 1 hour and 45 minutes the patient died. Due to the vague background of a sudden deterioration in the patient's condition, the case was brought for prosecution. The autopsy and histopathological studies did not reveal the cause of death, but undertaken chemico-toxicological examinations identified the presence of pancuronium in blood, liver and kidney (190 ng/ml, 70 ng/g and 125 ng/g, respectively). Chemico-toxicological analysis proved that the cause of death of the 57-year-old hospitalized woman was pancuronium intoxication due to evident medical error during drug administration. In our case the concentration of pancuronium in blood was in therapeutic range (200-600 ng/ml). However, even a therapeutic pancuronium dose administered to patient the breath of whom is not supported and monitored can be a threat to his life.

[S-adenosyl L-methionine in CNS diseases]. / S-adenozylo L-metionina w schorzeniach OUN.

S-adenosyl L-methionine (SAMe) is the natural, universal methyl group donor, participating in transmethylation reactions, known and commonly used as a dietary supplement since 1952. It plays an important role in the synthesis of neuromediators and melatonin and mechanisms of epigenetic regulation. The aim of this article is to review the literature about possibilities of SAMe application in the therapy of CNS diseases: depression, dementia syndromes, schizophrenia and somatic disorders. SAMe is the promising dietary supplement, which may be successfully used as a substance increasing effectiveness of the treatment of depression, with antidepressants in monotherapy in mild depressive states or depressive symptoms. SAMe addition to antipsychotic drug, may lead to the improvement of the quality of life and reduction of aggressiveness of patients. SAMe may be an effective substance in the therapy and prophylaxis of mild cognitive impairments and mild dementia syndrome. SAMe possesses some hepatoprotective action, so it may decrease the risk of the development of neoplasm, alcohol-induced liver disease (ALD) and cirrhosis. SAMe improves the functions of joints and decreases the experience of pain in rheumatoid arthritis (RA).
