Toxic leucoencephalopathy (TLE) is a rare neurological complication of heroin abuse. 'Chasing the dragon' is an inhalational mode of heroin abuse that originated in Southeast Asia. Intriguingly, no cases of TLE have been reported from this region, although the inhalational mode of heroin abuse is common. We herein report the case of a middle-aged man with a history of polysubstance abuse who pr...

A large and diverse group of coagulase-negative staphylococci were assayed for the ability to produce toxic shock syndrome toxin 1 (TSST-1) by immunological reactivity, and whole-cell DNAs from 33 of these strains were hybridized with a TSST-1-specific gene probe. None of the strains tested, including isolates that have been reported as TSST-1+, produced the exotoxin, and no DNA homology was fo...

adverse effects of antiepileptic drugs including cutaneous reactions may not only affect the result of treatment and quality of life, but can also be fatal if severe. skin rash is more likely to occur during the first few months of treatment. the objective of this study was description of skin rashes in users of four antiepileptic drugs. we identified skin rashes of phenytoin, carbamazepine, so...

Radioiodine therapy is the safest, simplest, least expensive and most effective method for treatment of hyperthyroidism. The method employed in this research was a systematic bibliographic review, in which only valid studies or the clinically detailed enough open-labeled studies using validated scales were used. Iodine-131 (I-131) acts by the destructive effect of short-range beta radiation on ...

background: dental clinics are known to be one of the largest users of toxic inorganic mercury. it is well documented that dentists and dental assistants who work with amalgam are chronically exposed to mercury vapor. this study investigates exposure to mercury vapor in a dental clinic. methods: gbc cold vapor atomic absorption spectrometry (aas), using sodium borohydride as the reducing agent,...

sediments are generally regarded as the sink for dissolved elements carried out to the sea by rivers. in order to study the source and mechanism of metal transport in sea water, 123 surface sediment samples were taken by using grab sampler in the northwest part of the persian gulf in summer. grain size analysis and geochemical analysis by icp-oes were carried out on samples after sample prepara...
