Successful smoking cessation with electronic cigarettes in smokers with a documented history of recurring relapses: a case series.

Beschreibung:

Smoking cessation programs are useful in helping smokers to quit, but smoking is a very difficult addiction to break and the need for novel and effective approaches to smoking cessation interventions is unquestionable. The E-cigarette is a battery-powered electronic nicotine delivery device that may help smokers to remain abstinent during their quit attempt. We report for the first time objective measures of smoking cessation in smokers who experimented with the E-cigarette.

WHO Study Group on Tobacco Product Regulation. Report on the scientific basis of tobacco product regulation: third report of a WHO Study Group.

Beschreibung:

This report presents the conclusions reached and recommendations made by the members of the WHO Study Group on Tobacco Product Regulation at its fifth meeting, during which it reviewed two background papers specially commissioned for the meeting and which dealt, respectively, with the following two themes. 1. Devices designed for the purpose of nicotine delivery to the respiratory system in which tobacco is not necessary for their operation. 2. Setting regulatory limits for carcinogens in smokeless tobacco. The Study Group's recommendations in relation to each theme are set out at the end of the section dealing with that theme; its overall recommendations are summarized in section 4.

Chronic idiopathic neutrophilia in a smoker, relieved after smoking cessation with the use of electronic cigarette: a case report.

Beschreibung:

Smoking is a major risk factor for a variety of diseases. Electronic cigarettes are battery-operated devices that deliver nicotine to the lungs by evaporation of a liquid. Chronic idiopathic neutrophilia is a condition characterized by elevated white blood cell and neutrophil counts without any underlying disease; smoking has been implicated as a potential cause.

Nicotine increases ciliary beat frequency by a direct effect on respiratory cilia.

Beschreibung:

We studied the direct effects of nicotine on the ciliary beat frequency (CBF) undisturbed by interference from mucus secretion by using epithelial strips from ferret tracheae which contain no goblet cells and, because the glands were left behind in the submucosa, no gland tissue either. Strips were studied in a chamber perfused with medium M-199 at 37 degrees C at a perfusion rate of 1.6 ml min-1 using a perfusion pump (Braun, Melsungen). CBF was determined photometrically, the signal being subjected to a fast Fourier transformation. We measured CBF continuously for 10 min (5 min with and 5 min without perfusion). Under baseline conditions without nicotine, it decreased from 23.4 +/- 0.8 to 22.2 +/- 0.5 Hz during perfusion and increased from 22.0 +/- 0.8 to 23.3 +/- 0.8 Hz during the subsequent period without perfusion. Nicotine increased CBF transiently, i.e., the effect was demonstrable only during perfusion, being strongest during the first 3 min of perfusion. At 10(-5) M, the increase in CBF was significant only during the 3rd minute, but at 10(-4) and 10(-3) M, CBF was elevated significantly throughout most of the perfusion period compared with control tissues perfused with medium M-199 only. Thus, at 2 min, CBF was 22.8 +/- 0.6 (mean +/- SE) in tissues perfused with medium M-199 only but was 24.3 +/- 0.8 Hz (NS, Student's unpaired t-test), 26.6 +/- 0.5 Hz (P = 0.001), and 26.8 +/- 1.2 Hz (P = 0.01) in tissues perfused with 10(-5), 10(-4), and 10(-3) M nicotine (dissolved in medium M-199), respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
