Clinical And Evolutive Characteristics in Acute Toxic Methemoglobinemia in Children

  Abstract Introduction: Acquired or toxic methemoglobinemia is the result of exposure by swallowing, inhalation or dermal absorbtion of medicines or non-drug chemicals with oxidizing properties. The main objectives of the study were to highlight the main causes of methemoglobinemia in children, to identify the associated factors and their influence on the clinical form of the disease as well as the response to antidote treatment with methylene blue. Methods: All patients with acute toxic methemoglobinemia hospitalized over a period of six years were included in the study, the inclusion criteria being: age < 18 years, suggestive symptomatology (generalized cyanosis, asthenia, dyspnea) and methemoglobin values >3%. Results: 82 patients with acute toxic methemoglobinemia were identified of which the majority (94%) were between 0-5 years. 69 cases were secondary to exposure to nitrates from water used to prepare food. The severity of methemoglobinemia was ...

Fulminant hepatic failure induced by antipsychotic drugs (a case report)

 Open Access Journal of Toxicology Introduction Fulminant hepatitis is a rare condition but has a very poor prognosis in the absence of liver transplantation. It is important to identify the cause as soon as possible to start the etiological treatment, which may be drug poisoning, viral hepatitis, or alcoholic ... [1-3]. N-acetylcysteine (NAC), a glutathione precursor, was first used as a treatment for paracetamol overdose in 1979. Since then, it has been firmly established as an effective and safe treatment for paracetamol induced IHC prevention. NAC has also been shown to be effective outside paracetamol intoxication. It has been evaluated as an option for acute IHC other than paracetamol in adults and children. In a randomized clinical trial comparing NAC with placebo in adults with paracetamol-free IHC, NAC was associated with a marked improvement in survival without liver transplantation [4]. NAC has also been evaluated for non-hepatic clinical conditions, these...

Further Studies in Translatable Model Systems are Needed to Predict the Impacts of Human Microplastic Exposure

Open Access Journal of Toxicology Abstract Microplastics are a pervasive environmental contaminant that have been found in many media including water sources, soils, and foodstuff. Due to the worldwide presence and persistence of microplastic debris, human exposure is inevitable. Human exposure occurs predominantly through ingestion, although dermal and inhalation exposures are probable. Microplastic single exposure studies in aquatic species and fish have shown various toxic effects including those on reproduction and survival. In addition to potential intrinsic toxicity, microplastics often have chemicals adsorbed to their surfaces. Studies report that these chemicals can have innate toxicity that is modulated by the composition of microplastics. Both the impacts of microplastics alone and co-exposures with adsorbed chemicals exhibit size dependent effects. Analysis of the current literature has revealed published studies predominantly investigate the toxicity of micropl...
