<p class="abstract"><strong>Background:</strong> Surgery for tympanic membrane perforation entails its own morbidity, risk of anesthesia, psychological trauma, along with long waiting periods for patients, especially in a tertiary care centre like ours. The purpose of this study was to evaluate outcomes of chemical cauterization and patching of perforation, performed as an office procedure in select cases.</p><p class="abstract"><strong>Methods:</strong> The study was conducted in a tertiary hospital from January 2016 to December 2017. The patients were selected based on the inclusion criteria, after thorough clinical assessment, examination under microscope and pure tone audiogram. All cases underwent cauterization of margins of perforation using 10% trichloroacetic acid (TCA), followed by patching with appropriately sized pre-sterilized cigarette paper patch. The patients were followed up weekly till the perforation was completely healed or till 12 weeks. If required, the procedure was repeated.  </p><p class="abstract"><strong>Results:</strong> 68 cases were included in the study. Most common site of perforation was antero-inferior quadrant of pars tensa. Most common etiology was inflammatory. Number of applications ranged from 1 to 3. The procedure was successful in 62 cases (91.2%). All cases with traumatic perforation, residual perforation post-surgery and persistent perforation after grommet extrusion healed well. All 6 cases with treatment failure had inflammatory etiology, 4 involving postero-superior quadrant.</p><p class="abstract"><strong>Conclusions:</strong> In patients with small, central, dry perforation of tympanic membrane, chemical cauterization using TCA and paper patching can yield results comparable to that of surgery, while abating the morbidity and psychological trauma of surgery and saving time for both patient and doctor.</p>

AbstractThe phenomenon of the smoulder stream flowing through the cigarette during smouldering and during the puff intervals is demonstrated for the first time and its dependence upon physical conditions is examined. The volume of the smoulder stream can amount up to 180 ml per cigarette. Increasing draw resistance of the cigarette and augmenting moisture content of the tobacco as well as perforation of the cigarette paper have a decreasing effect on volume and velocity of the smoulder stream. The porosity of the cigarette paper has no perceptible influence. The spatial position of the cigarette affects volume and velocity of the smoulder stream. The influence exercised by the smoulder stream on the yields of total condensate, nicotine, phenols, aldehydes, and acroleine when the cigarette tip is open during the puff intervals is determined. When the moisture contents of the tobacco were extremely high, yield decreases reaching 50 % could be observed.

AbstractA ventilating filter for cigarettes has been developed which reduces the delivery of smoke constituents from the final two to three puffs. Since the normaI delivery for these three puffs can account for up to half the total particulate matter and nicotine delivered by the whole cigarette, usefuI reductions per cigarette can be produced. The ventilating filter consists of cellulose acetate tow wrapped in heat-shrinkable film and attached to a tobacco rod using perforated tipping paper. When the cigarette is smoked, the perforations remain closed by contact with the impermeable film until transfer of heat to the filter is sufficient to soften the filter tow and shrink the film. Ventilating air now enters the cigarette and reduces the smoke deliveries. The effectiveness of the ventilating filter is increased by using films which have a low shrink temperature, high shrink tension and a high degree of biaxiaI shrinkage. Increases in filter plasticiser level, tipping perforation area and puff volume improve the effectiveness of the ventilating filter but increases in cigarette paper porosity and tobacco butt length reduce the effectiveness
