Wax Removal

Introduction: There are various methods of ear wax extraction and there are no specific guidelines on this subject. Many times we ask patients to instil some wax softening product for a few days and revisit for wax removal. This revisits result in increased cost, discomfort and loss of time. We conducted this study to determine the effectiveness of same-day ear wax removal as an office procedure with one or more techniques. Our secondary objective was to find the association between various factors and successful wax removal. Methods: During the study period, all patients with ear wax managed by a single ENT surgeon were included. History and examination were done and findings noted. One or more methods including probe, forceps, hooks, curette, suction, wax softening with wax softening agents, syringing were applied for wax removal. Complete wax removal was noted as success. Results: There were a total of 63 cases of ear wax among 34 participants. Wax was successfully removed in 52 (82.5%) cases in the same day. Presence of ear ache, narrow canal, complete obstruction and hard dry wax were adversely associated with successful wax removal. Presence of ear fullness, ear discharge, or use of ear drops in home was not significantly associated with successful ear wax removal. Conclusion: We were able to extract wax from a large proportion of patients on the same day of visit, thereby reducing their cost of revisit, however there were 17.5% of cases who could not be treated successfully on the same day.

Increasing environment noise pollution is a matter of great concern and of late has been attracting public attention. Sound produces the minute oscillatory changes in air pressure and is audible to the human ear when in the frequency range of 20Hz to 20 kHz. The chief sources of audible sound are the magnetic circuit of transformer which produces sound due to magnetostriction phenomenon, vibration of windings, tank and other structural parts, and the noise produced by cooling equipments. This paper presents the validation for sound level measurement scale, why A-weighted scale is accepted for sound level measurement, experimental study carried out on 10MVA Power Transformer. Also presents the outcomes of comparison between No-Load sound & Load sound level measurement, experimental study carried out on different transformer like - 10MVA, 50MVA, 100MVA Power Transformer, to define the dominant factor of transformer sound generation.

In the modern world, human recognition systems play an important role to   improve security by reducing chances of evasion. Human ear is used for person identification .In the Empirical study on research on human ear, 10000 images are taken to find the uniqueness of the ear. Ear based system is one of the few biometric systems which can provides stable characteristics over the age. In this paper, ear images are taken from mathematical analysis of images (AMI) ear data base and the analysis is done on ear pattern recognition based on the Expectation maximization algorithm and k means algorithm.  Pattern of ears affected with different types of noises are recognized based on Principle component analysis (PCA) algorithm.

ABSTRACT: The present study evaluated the efficacy of a single oral dose of doramectin in the control of Psoroptes ovis and Leporacarus gibbus in naturally infested rabbits. Sixteen adult rabbits were selected and distributed in two experimental groups. The treated group received 200 μg/Kg of oral doramectin and the control group received the same volume of saline solution. The diagnosis of the mites was made with a stereoscopic microscope. Hairs from the dorsal part of the neck, lumbar right, lumbar left, ventral side of the tail and ventral abdomen were evaluated for L. gibbus, and ear wax evaluated for P. ovis. The evaluation of the efficiency and the clinical assessment of the lesions was made in days 0, +3, +7, +14, +21, +28, and +35 after treatment. An efficacy of 75% and 87,5% was observed for L. gibbus in days +3 and +7 after treatment, an efficacy of 100% was observed in days +14, + 21, +28 e +35. An efficacy of 100% for the control of P. ovis was observed following day +7. The clinical lesion score of the control group remained unaltered, except for one animal which conditions worsened during experimentation. In the treated group animals, regression of the lesions was observed following day +3, and on day +21 no signal of infestation by P. ovis was present. None of the animals from the treated group presented secondary collateral effects caused by the doramectin, which proved itself as an optimal alternative for mite control in naturally infested rabbits.
