Introduction: The prevalence of polysubstance use is well described, but less is known about correlates and patterns of polysubstance use. Previous research characterized latent subgroups of substance users by the type substance used. Racial disparities in the prevalence of polysubstance use exist, particularly for American Indian/Alaska Native (AI/AN) populations. Read More

Background: Self-reported chemical sensitivity (SCS) is characterized by adverse effects due to exposure to low levels of chemical substances. The clinical manifestations of SCS are similar to the allergy, and a high percentage of individuals with both diseases have been found. Various genes, especially genes of importance to the metabolism of xenobiotic compounds, have been associated with SCS. Read More

Toluene is an organic solvent commonly misused by inhalation among adolescents to experience psychoactive effects. Repeated toluene exposure produces several cognitive deficits, including working memory impairment in which the medial prefrontal cortex (mPFC) plays a central role. Among other effects, toluene antagonizes NMDA receptors, enhance GABA receptor-mediated responses and increases dopamine release. Read More

Background: Molecular allergy has significantly improved the quality of allergy diagnosis; however, the positioning of singleplex and multiplex assays in the diagnostic algorithm is still a matter of debate.

Methods: Aim of the study was to test the analytical performance of the recently commercialized Allergy Explorer-ALEX® in a selected population (105 allergic patients and 15 negative controls), comparing it with the reference ImmunoCAP® method and with skin prick test (SPT).

Results: Inter-assay qualitative comparison showed a substantial agreement between ALEX® and SPT (k = 0. Read More

Purpose Of Review: Acute toxic inhalation exposures affect thousands of individuals worldwide each year. The acute evaluation of these inhaled exposures is often fraught with difficulty in identifying a specific agent, may involve multiple compounds, and a wide variety of responses are seen depending on the physical properties of the specific toxicant, the length of time of inhalation, and the concentration of the exposure. Recognizing key aspects of the most common acute toxic inhalations is useful in developing a diagnosis and treatment strategy. Read More

The pathology and impact of COPD results from an abnormal inflammatory process resulting in tissue damage with ineffective repair in response to toxic inhalants (especially cigarette smoke). Identification of mechanisms provides the opportunity to develop new therapies and a personalised approach to management. The collection of multiple genetic and detailed biochemical data from small and large patient cohorts has led to an explosion of studies investigating biomarkers, to achieve these aims. Read More

Inhalants are widely used as recreational drugs, and toluene is the main chemical compound present in most inhalants used for these purposes. Previous studies have shown that repeated toluene exposure produces cellular death and memory impairment, while environmental enrichment (EE) rescues from those effects. However, the mechanisms involved in those responses are unclear. Read More

Introduction: A school-based randomized controlled trial was conducted in 2014/2015 with students in 7 and 8 grades in 72 public schools in 6 Brazilian cities. A total of 5028 students were linked (75, 7%) in at least one of the two waves of follow-up (9 months and 21 months later). The principal research question was whether this 12-lesson program delays the initiation of alcohol, tobacco, inhalants and binge drinking among early adolescents when compared to usual care, that is, no prevention program in Brazilian schools, after 21 months of follow up.

Adolescent substance abuse remains common, with almost a third of adolescents admitting to ethanol use, and a quarter admitting to illicit drug use. It is essential for pediatricians to regularly screen adolescent patients for substance use, because early initiation of drug use has been associated with physical, behavioral, and social health risks. Adolescents abuse what is common and readily available; this includes ethanol, over-the-counter products, marijuana, and inhalants. Read More

Difluoroethane is the active ingredient in various computer cleaners and is increasingly abused by teenagers due to its ease of access, quick onset of euphoric effects, and lack of detectability on current urine drug screens. The substance has detrimental effects on various organ systems; however, its effects on the kidneys remain largely unreported. The following case report adds new information to the developing topic of acute kidney injury in patients abusing difluoroethane inhalants. Read More

Despite serious health effects, volatile industrial products containing toluene are deliberately inhaled for their psychoactive actions, mainly among adolescents and young adults. Chronic toluene inhalation induces multiple alterations at the cellular and behavioral level; however, modifications of neuronal networks associated with the reward system after repeated toluene exposure are not thoroughly characterized. Here we used whole-cell recordings to determine the effects of repeated exposure to toluene (1000, 4000 or 8000 ppm for 30 min, twice a day, for ten days) on the neurophysiological properties of prelimbic layer 5 pyramidal neurons of the medial prefrontal cortex (mPFC) in adolescent male Wistar rats.

The skin prick test (SPT) is the most common test for the diagnosis of allergy. SPT is performed by pricking the skin, usually in the volar surface of the forearm, with a lancet through a drop of an allergen extract and is usually the first choice test in the diagnostic workup for allergic diseases because of its reliability, safety, convenience and low cost. SPT is minimally invasive and has the advantage of testing multiple allergens in 15 to 20 min. Read More
