UNLABELLED Secretory otitis media (SOM) and recurrent acute otitis media (RAOM) may require surgical treatment to proper ventilate the middle ear. Incisional myringotomy is usually done under microscopy with a micro-knife, but it remains patent for just a few days. Recent research indicates that laser assisted myringotomies remain open much longer, allowing middle ear ventilation and healing. ...

Nontypeable Haemophilus influenzae (NTHi) is associated with chronic otitis media (COM). In this study, we generated a murine model of COM by using eustachian tube (ET) obstruction and NTHi (10(7) CFU) inoculation into the tympanic bulla, and we investigated the relationship between regulatory T cells (Treg) and chronic inflammation in the middle ear. Middle ear effusions (MEEs) and middle ear ...

background: otitis media with effusion (ome) is common in the children. it is proven that pathogenic bacteria as a causative agent of middle ear effusion, however the role of fungal infection in otitis media with effusion remains unclear. therefore, this study was conducted to assess presence of fungi in ome. methods: from january 2005 to september 2006, a number of 62 children with proven otit...

The buried hetero-structure (BH) InGaAsP-InP waveguide is used for asystem of double microring resonators (DMR). The light transmission and location ofresonant peaks are determined for six different sets of ring radii with different ordermode numbers. The effect of changing middle coupling coefficient on the box likeresponse is studied. It is found that the surge of coupling coefficient to the ...

Background: Internet is an important source of online health information seeking. Middle-aged people, may face more health-threatening challenges if they lack seeking skills. Therefore, the evaluation of seeking skills on health information in middle-aged people needs to be further studied. Objectives: The purpose of this paper was to examine the Online Health Information-Seeking Skills (OHISS...

The excellent preservation of the acritarchs, their great abundance, diversity and good stratigraphic control permit establishment of a detailed Middle and Late Cambrian acritarch biozonation. A total of 56 palynomorph species form the basis of 10 local acritarch assemblage zones. Assemblage zones I-II occur in the lower and middle parts of the Member C of the Mila Formation and suggest Early-m...

introduction: first branchial cleft anomalies manifest with duplication of the external auditory canal.   case report: this report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. external auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...
