ingested corrosive substances produce different injuries, ranging from minor gastro esophageal burns to death, depending on the agent type, amount, concentration, and duration of substance exposure. the purpose of this study was to investigate the outcomes and different causes of mortality in patients ingesting caustic substances. in a prospective study, between april 1999 and january 2006, a t...

background: this study was focused on the probability of carcinogen risk of low-level ingestion and dermal exposure with polycyclic aromatic hydrocarbons (pahs) from drinking water in tehran, capital of iran. methods: concentrations of 16 pahs were measured in the tap, bottled and heated tap water in four different seasons. using a questionnaire-based survey, exposure with pahs from drinking wa...

Introduction Radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. Therefore, entrance skin dose (ESD), body organ dose (BOD), and effective dose (ED) from adult patients undergoing routine thorax posterior-anterior (PA) and thorax right lateral (RLAT) were estimated in Uni...

Determination of radionuclide transfer from animal feeds to products and ingestion rates is important in assessing internal radiation risk humans who consume the products. Seventy-nine (79) pasture samples milk were collected cattle farms seven sub-counties. Activity concentrations radionuclides determined using gamma spectroscopy. Transfer ratios calculated. Ingestion cow also determined. Radi...

Ingestion of ethanol in the presence of disulfiram may cause a histamine-like reaction due to accumulation of acetaldehyde. These disulfiram-ethanol reactions (DERs) are manifested by hypotension, tachycardia, gastritis, and angioedema. Fomepizole, an inhibitor of alcohol dehydrogenase, may halt progression of this reaction by blocking ethanol metabolism to acetaldehyde. We present 2 cases of d...

Individuals are exposed to volatile compounds present in tap water by ingestion, inhalation, and dermal absorption. Traditional risk assessments for water often only consider ingestion exposure to toxic chemicals, even though showering has been shown to increase the body burden of certain chemicals due to inhalation exposure and dermal absorption. We collected and analyzed time-series samples o...

Introduction: The CT Provide high quality images, especially in low-contrast soft tissue, are another advantage. Along with all the benefits that the CT scans which have, the patient dose of this modality is much greater than other methods. As a result, medical imaging community must ensure that the benefits of radiological examination for each patient are higher than related r...

Acetaminophen (AAP) is a commonly analgesic found in numerous non-prescription pharmaceuticals. High dose and chronic ingestion of AAP caused renal toxicity. This study designed to assess the possible nephroprotective role flaxseed oil (FSO) male rats. Nephrotoxicity was induced rats via ingested single (3 g/kg). Five groups were used; Control, AAP, FSO (1.5 ml/kg) + (4.5 AAP. Rats received ora...
