Otitis media is a group of inflammatory diseases of the middle ear. [2] One of the two main types is acute otitis media (AOM), [3] an infection of rapid onset that usually presents with ear pain. [1] In young children this may result in pulling at the ear, increased crying, and poor sleep. [1] Decreased eating and a fever may also be present. [1]
Rarely, Mycobacterium species can also cause the infection. Some mastoiditis is caused by cholesteatoma, which is a sac of keratinizing squamous epithelium in the middle ear that usually results from repeated middle-ear infections. If left untreated, the cholesteatoma can erode into the mastoid process, producing mastoiditis, as well as other ...
Otomycosis does not usually cause as much canal skin edema as does acute bacterial external otitis.While a severe pressure type of pain is a prominent feature of advanced cases, the ear is usually much less tender, if at all, to traction or tragal pressure.
A common cause of primary otalgia is ear infection called otitis media, meaning an infection behind the eardrum. [3] The peak age for children to get acute otitis media is ages 6–24 months. One review paper wrote that 83% of children had at least one episode of acute otitis media by 3 years of age. [10]
The most common aetiology of acute otitis externa is bacterial infection, [5] while chronic cases are often associated with underlying skin diseases such as eczema or psoriasis. [6] A third form, malignant otitis externa, or necrotising otitis externa, is a potentially life-threatening, invasive infection of the external auditory canal and ...
Haemophilus influenzae (formerly called Pfeiffer's bacillus or Bacillus influenzae) is a Gram-negative, non-motile, coccobacillary, facultatively anaerobic, capnophilic pathogenic bacterium of the family Pasteurellaceae. The bacteria are mesophilic and grow best at temperatures between 35 and 37 °C. [1]
Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. It causes the infection of the host cell by sticking to the host cell using trimeric autotransporter adhesins.
