Inhaled Toxins

چکیده
Many airborne toxins produce local noxious effects on the airways and lungs as irritants. The respiratory tract can also serve as a portal of entry for systemic poisons as simple or systemic asphyxiants. Inhalational exposure can be covert and indolent (as in occupational exposure to asbestos or urban exposure to photochemical smog) or fulminant and obvious. The circumstances and location of the exposure, the presence of combustion or odors, and the number and condition of victims assist in the diagnosis. Despite the array of possible toxic inhalants, identification of a specific inhalant is generally unnecessary because therapy is based primarily on the clinical manifestations (Table 159-1).

Evaluation of a vaporizing device (Volcano) for the pulmonary administration of tetrahydrocannabinol.
What is currently needed for optimal use of medicinal cannabinoids is a feasible, nonsmoked, rapid-onset delivery system. Cannabis "vaporization" is a technique aimed at suppressing irritating respiratory toxins by heating cannabis to a temperature where active cannabinoid vapors form, but below the point of combustion where smoke and associated toxins are produced. The goal of this study was t...
متن کاملEffect of Particulate Properties of Inhaled Dry Powder Formulation on Bioavailability, Dissolution Rate of Drug Particles and Rate of Drug Removal from the Body
Introduction: The use of pulmonary drug delivery as a non-invasive drug delivery system for the systemic treatment of diseases as well as the topical treatment of respiratory diseases is increasing. Among the various inhaled formulations, inhaled dry powders show advantages over the other forms of inhaled medicines due to high stability, bioavailability and ease of use. The effect of particle p...
متن کاملPulmonary Alveolar Proteinosis in Setting of Inhaled Toxin Exposure and Chronic Substance Abuse
Pulmonary alveolar proteinosis (PAP) is a rare lung disorder in which defects in alveolar macrophage maturation or function lead to the accumulation of proteinaceous surfactant in alveolar space, resulting in impaired gas exchange and hypoxemia. PAP is categorized into three types: hereditary, autoimmune, and secondary. We report a case of secondary PAP in a 47-year-old man, whose risk factors ...

Idiopathic chronic eosinophilic pneumonia (ICEP) is a rare form of diffuse parenchymal lung disease first identified by Carrington et al. in 1969. It is characterized by the presence of constitutional and respiratory symptoms with associated peripheral opacities on imaging and elevated serum and/or bronchoalveolar eosinophilia. Although data is limited regarding etiology or prevalence, it is kn...
متن کاملToxin mixture in cyanobacterial blooms--a critical comparison of reality with current procedures employed in human health risk assessment.
Cyanobacteria are the oldest life forms on earth known to produce a broad spectrum of secondary metabolites. The functions/advantages of most of these secondary metabolites (peptides and alkaloids) are unknown, however, some of them have adverse effects in humans and wildlife, especially when ingested, inhaled or upon dermal exposure. Surprisingly, some of these cyanobacteria are ingested volun...
