A bacteriological study of CSOM in Konaseema region

Abstract

Background: Chronic Suppurative Otitis Media is a disease of multiple aetiology and is well known for its persistence and recurrence in spite of treatment. Changes in the microbiological profile following the advent of sophisticated synthetic antibiotics and unscrupulous usage of antibiotics increase the relevance of reappraisal of the modern day organisms in CSOM and their in vitro antibiotic sensitivity pattern. Aim: To identify bacteriological profile in our geographical area in CSOM both in TTD and AAD types, their latest sensitivity trends to antibiotics. Materials & Methods: 100 Patients with more than 3 months history of ear discharge selected over a period of 18 months. All patients are enquired about the history then subjected to ENT examination. From the discharging ear, pus taken with two sterile swabs and sent for direct smear and aerobic culture and sensitivity. Results: Gram negative organisms are predominant than gram positive. Pseudomonas is the most common organism found followed by Staph. aureus. Sensitivity in gram negative bacteria were mainly to Ciprofloxacin, Gentamycin and Amikacin. The gram positive organisms were highly sensitive to Amoxycillin/Clavulanic acid, Amikacin, Gentamycin, Ciprofloxacin and Tetracycline. Conclusion: Bacterial profile in discharging ears keep changing, latest bacteriological profile with antibiotic sensitivities needed to be obtained from time to time so as to treat the patient more efficiently.

A comparative study of tympanoplasty with or without mastoidectomy in tubotympanic type of chronic suppurative otitis media

“…In the study conducted by Raju et al, similar observation was made with 53% males and 47% females. 8 Male preponderance was also observed by Kumar et al in which 52% were males and 48% were females. 9 The possible reason for high predominance in males could be, because our society is conservative where men have more privileges when compared with women in being taken to tertiary centers for treatment and they indulge in outdoor work.…”

Recent Progress in Hexagonal Ferrites Based Composites for Microwave Absorption

“…Due to the composites' high attenuation of electromagnetic waves may be employed as antiradar devices and shielding materials to reduce electromagnetic interference. [183] Numerous researchers have synthesized nanocomposites materials capable of absorbing EM radiation, including ferrite/polymer, [184][185][186][187][188][189][190][191][192][193][194] graphene/polymer, [195][196][197][198][199][200][201][202] hexaferrite/polymer, [203][204][205] polyaniline/carbon nanotube, [206][207][208][209][279][280][281][282] and polyaniline/MWCNT nanocomposite. In situ polymerization of MWCNTs/BaM/PANI was used by Afghahi et al [210] Their process begins with 30 min of mixing 10 cm 3 DBSA with water.…”
