REVIEW
Kshipra Naik, Meenal Kowshik
Silver has attracted a lot of attention as a powerful, broad spectrum and natural antimicrobial agent since the ancient times because of its non-toxic nature to the human body at low concentrations. It has been used in treatment of various infections and ulcers, storage of water, and prevention of bacterial growth on the surfaces and within materials. However there are numerous medical and health benefits of colloidal or nano silver apart from its microbicidal ability which as yet have not been fully embraced by the medical community...

Carbon monoxide (CO) inhalation is nowadays the most common cause of fatal poisoning worldwide. CO binds to haemoglobin 230-270 times more avidly than oxygen, thus leading to formation of carboxyhaemoglobin with subsequent reduction of tissue oxygenation. Brain is mainly affected due to its high oxygen requirement. Up to two-thirds of patients who survive the acute phase of this pathology present a delayed leukoencephalopathy, usually in a period ranging from two to 40 days. White matter damage closely relates to long-term prognosis of these patients...

BACKGROUND: Thermal injury is the main cause of pulmonary disease in stroke after burn and can be life threatening. Heat-induced inflammation is an important factor that triggers a series of induces pathological changes. However, this mechanism underlying heat-induced inflammation in thermal inhalation injury remains unclear. Studies have revealed that astragaloside-IV (AS-IV), a natural compound extracted from Astragalus membranaceus, has protective effects in inflammatory diseases. Here, we investigated whether the protective effects of AS-IV occur because of the suppression of heat-induced endoplasmic reticulum (ER) stress and excessive autophagy Methods: AS-IV was administered to Wistar rats after thermal inhalation injury and 16HBE140-cells were treated with AS-IV...

Hypersensitivity pneumonitis (HP) is an immune-mediated pulmonary disorder involving inflammation of the lung interstitium, terminal bronchioles, and alveoli caused by the immune response to the inhalation of an offending environmental airborne agent. It can manifest as exertional dyspnea, fatigue, weight loss, and progressive respiratory failure if left untreated. Because of its protean features, it can be misdiagnosed as other common obstructive lung conditions such as asthma. If triggers are not avoided, it can progress to irreversible pulmonary fibrosis...

Engineered nanomaterials (ENMs), or small anthropogenic particles approximately < 100 nm in size and of various shapes and compositions, are increasingly incorporated into commercial products and used for industrial and medical purposes. There is an exposure risk to both the population at large and individuals in the workplace with inhalation exposures to ENMs being a primary concern. Further, there is increasing evidence to suggest that certain ENMs may represent a significant health risk, and many of these ENMs exhibit distinct similarities with other particles and fibers that are known to induce adverse health effects, such as asbestos, silica, and particulate matter (PM)...

Diisocyanates are highly reactive electrophiles utilized in the manufacture of a wide range of polyurethane products, and have been identified as causative agents of occupational allergic respiratory disease. However, in spite of the significant occupational health burden associated with diisocyanate-induced asthma, the mechanism of disease pathogenesis remains largely unknown. To better understand the fate of inhaled diisocyanates, a nose-only aerosol exposure system was constructed and utilized to expose a BALB/c mouse model to aerosol generated from 4,4'-methylene diphenyl diisocyanate (MDI)...

Although asthma, a chronic inflammatory airway disease, is relatively well-managed by inhaled corticosteroids, the side effects associated with the long-term use of these agents precipitate the need for alternative therapeutic options based on differing modes of action. Bilirubin, a potent endogenous antioxidant, and anti-inflammatory molecule have been shown to ameliorate asthmatic symptoms; however, its clinical translation has been limited owing to its water insolubility and associated potential toxicity...

BACKGROUND: Opioid analgesics decrease the minimum alveolar concentration of inhalation agents during the acute phase response. However, the effect of chronic opioid exposure on minimum alveolar concentration of inhalation agents remains unknown. This study aimed to determine the concentration of sevoflurane necessary to maintain a bispectral index (BIS) <50 (SEVOBIS50) in patients with chronic opioid use compared with those naïve to opioid use. METHODS: We included chronic opioid users who received a stable dose of oral morphine of at least 60 mg/d according to the morphine equivalent daily dose for at least 4 weeks and opioid-naïve patients...

Nitrous oxide and midazolam have been used as sedative agents to decrease fear and anxiety associated with dental procedures. Although these agents have been widely used individually, the combination of the two is also commonly used. Four clinical trials were identified that compared the combination technique with the individual use of the drugs. The standardized mean difference (SMD) for each outcome measure was considered for final analysis. Three studies with 534 participants were included in the final meta-analysis, and the SMD [95% CI] was obtained as -0...

AGC(®) (Automatic Gas Control) is the FLOW-i's automated low flow tool (Maquet, Solna, Sweden) that target controls the inspired O2 (FIO2) and end-expired desflurane concentration (FAdes) while (by design) exponentially decreasing fresh gas flow (FGF) during wash-in to a maintenance default FGF of 300 mL min(-1). It also offers a choice of wash-in speeds for the inhaled agents. We examined AGC performance and hypothesized that the use of lower wash-in speeds and N2O both reduce desflurane usage (Vdes). After obtaining IRB approval and patient consent, 78 ASA I-II patients undergoing abdominal surgery were randomly assigned to 1 of 6 groups (n = 13 each), depending on carrier gas (O2/air or O2/N2O) and wash-in speed (AGC speed 2, 4, or 6) of desflurane, resulting in groups air/2, air/4, air/6, N2O/2, N2O/4, and N2O/6...

OBJECTIVE: N-butane and n-pentane can both produce general anesthesia. Both compounds potentiate γ-aminobutyric acid type A (GABAA) receptor function, but only butane inhibits N-methyl-d-aspartate (NMDA) receptors. It was hypothesized that butane and pentane would exhibit anesthetic synergy due to their different actions on ligand-gated ion channels. STUDY DESIGN: Prospective experimental study. ANIMALS: A total of four Xenopus laevis frogs and 43 Sprague-Dawley rats...

REVIEW
Matthew Loxham, Donna E Davies
The bronchial epithelium is continuously exposed to a multitude of noxious challenges in inhaled air. Cellular contact with most damaging agents is reduced by the action of the mucociliary apparatus and by formation of a physical barrier that controls passage of ions and macromolecules. In conjunction with these defensive barrier functions, immunomodulatory cross-talk between the bronchial epithelium and tissue-resident immune cells controls the tissue microenvironment and barrier homeostasis. This is achieved by expression of an array of sensors that detect a wide variety of viral, bacterial, and nonmicrobial (toxins and irritants) agents, resulting in production of many different soluble and cell-surface molecules that signal to cells of the immune system...

BACKGROUND: Kanamycin, an injectable agent, is currently used to treat drug-resistant tuberculosis (TB). Parenteral kanamycin causes high systemic toxicity which could be avoided by direct delivery to the lungs. This study focused on producing a highly aerosolizable dry-powder of hygroscopic kanamycin by spray-drying with l-leucine. METHODS: Kanamycin powders were prepared with different concentrations (0, 5, 10, 15 and 20% w/w) of l-leucine using the Buchi B-290 Mini Spray-Dryer...

Lipopolysaccharide (LPS) contributes to asthma exacerbations and development of inhaled corticosteroid insensitivity. Complete resistance to systemic corticosteroids is rare and most patients lie on a continuum of steroid responsiveness. The objective of this study was to examine the sensitivity of combined ovalbumin- (Ova) and LPS-induced functional and inflammatory responses to inhaled and systemic corticosteroid in conscious guinea-pigs, to test the hypothesis that the route of administration affects its sensitivity...
