A questionable diagnosis in a woman with drowsiness
2019
A 60-year-old caucasian woman was admitted to our Division of Internal Medicine for a 10-day history of drowsiness, irritability, dysphasia, weakness and difficulties in the maintenance of an upright position with numerous falls, with a traumatic lumbar spine injury and on the left shoulder. Then, while general clinical conditions were getting worse with drowsiness and hyposthenia of the right side of the body, after neurological evaluation, she was recovered in hospital. Pathological history includes a 20-year epilepsy and depression with emotional lability, behavior’s disorders and attempted suicide. For such reason, she was followed in a mental health institute, treated with phenobarbita…
Determination of propofol by GC/MS and fast GC/MS-TOF in two cases of poisoning
2017
Two cases of suspected acute and lethal intoxication caused by propofol were delivered by the judicial authority to the Department of Sciences for Health Promotion and Mother-Child Care in Palermo, Sicily. In the first case a female nurse was found in a hotel room, where she lived with her mother; four 10 mg/mL vials and two 20 mg/mL vials of propofol were found near the decedent along with syringes and needles. In the second case a male nurse was found in the operating room of a hospital, along with a used syringe. In both cases a preliminary systematic and toxicological analysis indicated the presence of propofol in the blood and urine. As a result, a method for the quantitative determina…
Molecular mechanisms of Id2 down-regulation in rat liver after acetaminophen overdose. Protection by N-acetyl-L-cysteine.
2010
Id2 is a pleiotropic protein whose function depends on its expression levels. Id2-deficient cells show increased cell death. This study explored the molecular mechanisms for the modulation of Id2 expression elicited by GSH and oxidative stress in the liver of acetaminophen (APAP)-intoxicated rats. APAP-overdose induced GSH depletion, Id2 promoter hypoacetylation, RNApol-II released and, therefore, Id2 down-regulation. Id2 expression depends on c-Myc binding to its promoter. APAP-overdose decreased c-Myc content and binding to Id2 promoter. Reduction of c-Myc was not accompanied by decreased c-myc mRNA, suggesting a mechanism dependent on protein stability. Administration of N-acetyl-cystein…
The pathogenetic role of adulterants in 5 cases of drug addicts with a fatal outcome
2013
The purpose of the present study is to determine the role of lidocaine, caffeine and dextromethorphan, used as adulterant substances, in five cases of drug overdose which have come to our attention. Taking into account the pharmacological mechanism, blood concentration and route of administration (intravenous) we evaluated the hypothesis that these substances could act with a synergistic effect - or at least additive - with the illicit drugs on the central nervous system and cardiovascular system.
The role of the hospital pharmacy in the storage and supply of antidotes
2013
Cases of poisoning have been analyzed with the aim of estimating both the incidence and the seriousness of such xenobiotic effects, the major determinant agents, and the related antidotes used in hospital departments. From 2009 to November 2012, a survey of the availability of antidotes in the emergency room services was carried out in all hospital pharmacies under the Palermo Health Authority: Policlinico Paolo Giaccone, ARNAS Civico di Cristina Benefratelli, Azienda Ospedaliera Ospedali Riuniti Villa Sofia-Cervello. Figures show that the majority of poisoning events were caused by the use/abuse of drugs, especially psychopharmaceuticals, alcohol and narcotic substances. This overdose of m…
Fatal cerebellar haemorrhage due to phenprocoumon poisoning.
1996
A 32-year-old patient died of a cerebellar haemorrhage and the blood coagulation analysis before death suggested defective synthesis of vitamin K-dependent clotting factors due to vitamin K deficiency. The post-mortem toxicological examination of different tissues revealed phenprocoumon poisoning as the cause of death. The differential diagnosis of vitamin K deficiency and the toxicology of hydroxycoumarins are discussed.
Zunehmende Bedeutung von Antidepressiva bei suizidalen und parasuizidalen Intoxikationen
2002
BACKGROUND AND OBJECTIVE: Antidepressant drugs are frequently used in deliberate self-poisoning resulting in a major risk for the patients due to their cardiac and central-nervous toxicity. In the present study the cases of intoxications consulting our Poison Center should be analysed illustrating recent results and trends about self-poisoning with antidepressants. PATIENTS AND METHODS: During the study period from 1995 to 2001 35 394 inquiries concerning deliberate self-poisoning were registered in our Poison Center. The substance used, age and gender of the patient as well as the degree of the observed symptoms were documented. Thereby, antidepressant drugs were grouped in tricyclic antid…
An unusual fatal case of overdose of Vinblastine and review of literature
2017
The pharmacological treatment of neoplasia is based on the use of chemotherapeutic substances. Chemotherapeutic agents can cause acute and chronic toxicity even at therapeutic doses. For this reason their overdose puts a patientâs life at severe risk. This work presents an unusual fatal case of overdose subsequent to an accidental massive administration of Vinblastine (90Â mg instead of 9Â mg), slow bolus (five minutes), to a 33-year-old woman who suffered from Hodgkinâs Lymphoma. The administration of the massive dose was due to a transcription error of the therapeutic treatment plan and miscommunication between the health professionals which caused the use of the wrong dose. The foren…
Analysis of suicide attempts among children hospitalised in the Department of Paediatrics in Zabrze in 2010–2016
2018
Introduction: Despite the current decline in the number of suicides, they are the second most common cause of death among children and adolescents. At the end of the 20th century, suicides represented about 10% of all causes of death of people up to 18 years old, but currently they reach up to 20%. Over the years, the number of suicide attempts (SA) has also increased. Aim of the study: The aim of the study was to analyse the cases of hospitalisation of children in the Department of Paediatrics of the Independent Public Clinical Hospital No. 1 in Zabrze (DP IPCH1) due to a suicide attempt. Material and methods: Medical records of 87 patients hospitalised due to SA in the years 2010–2016 in …
