Each year, synthetic cannabinoids are occurring in high numbers on the illicit drug market but data obtained after controlled application are rare. The present study on pharmacokinetics in urine is part of a pilot study on adverse effects of JWH-018, which is one of the oldest and best known synthetic cannabinoids. Six subjects inhaled smoke from 2 and 3mg JWH-018. The drug and ten potential metabolites were analyzed in urine samples collected during 12h after inhalation by liquid chromatography-mass spectrometry (LC-MS/MS) without and with conjugate cleavage...

RATIONALE: Many in-hospital cardiac arrests are precipitated by hypotension, often associated with systemic inflammation. These patients are less likely to be successfully resuscitated and novel approaches to their treatment are needed. OBJECTIVES: To determine if the addition of inhaled nitric oxide (iNO) to hemodynamic-directed cardiopulmonary resuscitation (HD-CPR) would improve short-term survival from cardiac arrest associated with shock and systemic inflammation...

Nanotechnology offers innovation in products from cosmetics to drug delivery, leading to increased engineered nanomaterial (ENM) exposure. Unfortunately, health impacts of ENM are not fully realized. Titanium dioxide (TiO2) is among the most widely produced ENM due to its use in numerous applications. Extrapulmonary effects following pulmonary exposure have been identified and may involve reactive oxygen species (ROS). The goal of this study was to determine the extent of ROS involvement on cardiac function and the mitochondrion following nano-TiO2 exposure...

Benzyl alcohol, benzoic acid and its salts, and benzyl benzoate function mostly as fragrance ingredients/preservatives in cosmetic products. The Cosmetic Ingredient Review Expert Panel previously established concentration limits for benzyl alcohol, benzoic acid, and sodium benzoate in cosmetics and determined that the available data were insufficient to support the safety of these ingredients during inhalation exposure. After reviewing newly available data, it was concluded that benzyl alcohol, benzoic acid and its salts, and benzyl benzoate are safe in the present practices of use and concentration described in this safety assessment...

Inhalation of ozone (O3), a gaseous air pollutant, causes lung injury, lung inflammation, and airway hyperresponsiveness. Macrophages, mast cells, and neutrophils contribute to one or more of these sequelae induced by O3 Furthermore, each of these aforementioned cells express chemokine (C-C motif) receptor-like 2 (Ccrl2), an atypical chemokine receptor that facilitates leukocyte chemotaxis. Given that Ccrl2 is expressed by cells essential to the development of O3-induced lung pathology and that chemerin, a Ccrl2 ligand, is increased in bronchoalveolar lavage fluid (BALF) by O3, we hypothesized that Ccrl2 contributes to the development of lung injury, lung inflammation, and airway hyperresponsiveness induced by O3 To that end, we measured indices of lung injury (BALF protein, BALF epithelial cells, and bronchiolar epithelial injury), lung inflammation (BALF cytokines and BALF leukocytes), and airway responsiveness to acetyl-β-methylcholine chloride (respiratory system resistance) in wild-type and mice genetically deficient in Ccrl2 (Ccrl2-deficient mice) 4 and/or 24 hours following cessation of acute exposure to either filtered room air (air) or O3 In air-exposed mice, BALF chemerin was greater in Ccrl2-deficient as compared to wild-type mice...

Essential oils (EOs), also known as volatile oils, are concentrated natural plant products which contain volatile aroma compounds. Most EOs are derived by steam distillation, a tradition which can be traced back as many as 5000 years. They possess unique properties which result in various possibilities for application, also in modern medical contexts. Areas for medical aromatherapy include respiratory diseases, pain management or stress alleviation, amongst many others. Different modes of application exist: The rich ingredients can be absorbed by the body by anointment, gentle massage, inhalation, or oral intake of capsules...

BACKGROUND: There are few studies addressing the longitudinal analysis of vitamin D deficiency and its impact to the development of atopic diseases in early childhood. METHODS: We investigated 155 children who regularly followed up at our clinic for 5 years as subjects enrolled in a birth cohort study. The pattern of vitamin D levels from birth to 5 years of age was clustered using K-means method in R software. Absolute eosinophil count (AEC), total serum and specific immunoglobulin E antibodies against food (egg white, milk, and wheat) and inhalant allergens (D...

Flavoring a facemask with a lip balm for inhalational induction in children is a common practice. However, most anesthesia providers are unaware of potential complications and the management of allergic reactions caused by lip balm. We describe the occurrence of allergic reaction to lip balm-flavored facemask in a child who underwent an inhalational anesthetic induction. The facial rash resolved completely without complications after administration of an antihistamine and steroid.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4...

Ensuring adequate ventilation and oxygenation and delivering inhaled anesthetic agent to the patient remain core responsibilities of the anesthesia provider during general anesthesia. Because of the emphasis placed on physiology, pharmacology, clinical sciences, and administrative duties, the stellar anesthesia workstation technology may be underutilized by the anesthesia community. Target-controlled O2 and agent delivery and automated end-expired CO2 control have entered the clinical arena, with only cost, luddism, and administrative hurdles preventing their more widespread use...

AIM: To describe the experience of using a "Burns Extrication Form" at a regional Burns Centre. Communication between the fire services and burns team previously has been regarded as poor. Significant information is collected by the fire services at the scene and this can aid the management of the patient. METHODS: The Burns Extrication Form was devised to provide a clear framework of communication between the two services. Information regarding time frames, exposure to heat & smoke, fire loading (potential severity of a fire in a given space by measuring amount of combustible material in confined space), building construction, chemicals involved is passed to the medical team through this form through a National Health Service mailbox...

REVIEW
M Mosing, J M Senior
In the first edition of this journal Barbara Weaver wrote a review titled 'Equine Anaesthesia' [1], stating, that, at that time it was quickly becoming accepted practice that many horses were being anaesthetised "by essentially similar procedures, i.e. premedication, induction and then maintenance by controlled inhalation". Her review focussed upon the last procedure. Maintenance of anaesthesia through controlled inhalation implies that an anaesthetic agent can be suitably delivered via the respiratory system and that ventilation is sufficiently maintained to deliver that agent and maintain adequate gas exchange...

The Objectives of the study were to investigate whether 400 µg inhaled salbutamol influences 3 km running time-trial performance and lung function in eucapnic voluntary hyperpnoea positive (EVH+ve) and negative (EVH-ve) individuals. Fourteen male participants (22.4 ± 1.6yrs; 76.4 ± 8.7kg; 1.80 ± 0.07 m); (7 EVH+ve; 7 EVH-ve) were recruited following written informed consent. All participants undertook an EVH challenge to identify either EVH+ve (↓FEV1>10%) or EVH-ve (↓FEV1<10%). Participants performed three separate 3 km running time-trials in a low-humidity (20-25%) environment on a non-motorized treadmill, 15 minutes following inhalation of salbutamol (400 µg), placebo (non-active inhalant) or control (no inhalant), in a randomized, single-blind, repeated measures design...

Rationale: DPP-4 may regulate immunological pathways implicated in asthma. Assessing whether DPP-4 inhibitor (DPP-4i) use might affect asthma control is clinically important because DPP-4i use in type 2 diabetes mellitus management (T2DM) is increasing. This study evaluated associations between DPP-4i use and asthma control. Methods: This was a retrospective, observational, matched cohort study using administrative claims in the MarketScan® Commercial Claims and Encounters (Commercial) and Medicare Supplemental and Coordination of Benefits (Medicare Supplemental) databases...

Luisa Brussino, Paolo Solidoro, Giovanni Rolla
Severe asthma is defined as asthma that requires treatment with high-dose inhaled corticosteroids (ICSs) plus a second controller and/or systemic corticosteroids to prevent it from becoming uncontrolled or that remains uncontrolled despite this therapy. This definition has limitations: 1) it does not define any biological characteristic that distinguishes severe asthma from asthma in general and 2) it relies on the clinical interpretation of asthma symptoms that are not specific. Actually, wheezing, dyspnea, cough and chest tightness may be caused by the comorbidities (such as rhinosinusitis, obesity and vocal cord dysfunction [VCD]) which are associated with asthma...

Background: Exacerbation history is used to grade the risk of COPD exacerbation, but its reliability and relationship to other risk factors and prior therapy is unclear. To examine these interrelationships, we conducted a post hoc analysis of patients in the TIOSPIR trial with ≥2 years' follow-up or who died on treatment. Patients and methods: Patients were grouped by their annual exacerbation rate on treatment into nonexacerbators, infrequent, and frequent exacerbators (annual exacerbation rates 0, ≤1, and >1, respectively), and baseline characteristics discriminating among the groups were determined...
