[3][4] This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. [5]: 28 ...
Orbital cellulitis is inflammation of eye tissues behind the orbital septum. It is most commonly caused by an acute spread of infection into the eye socket from either the adjacent sinuses or through the blood. It may also occur after trauma. When it affects the rear of the eye, it is known as retro-orbital cellulitis.
Health care providers distinguish bacterial and viral sinusitis by watchful waiting. [1] If a person has had sinusitis for fewer than 10 days without the symptoms becoming worse, then the infection is presumed to be viral. [1] When symptoms last more than 10 days or get worse in that time, then the infection is considered bacterial sinusitis. [53]
Acute infectious thyroiditis (AIT) also known as suppurative thyroiditis, microbial inflammatory thyroiditis, pyrogenic thyroiditis and bacterial thyroiditis. [1][2][3] The thyroid is normally very resistant to infection. Due to a relatively high amount of iodine in the tissue, as well as high vascularity and lymphatic drainage to the region ...
Treatment options depend on the nature of an individual's post-nasal drip and its cause. Antibiotics may be prescribed if the PND is the result of bacterial sinusitis. [ 8 ] In cases where PND is caused by allergic rhinitis or irritant rhinitis, avoidance of allergens or irritating factors such as dander, cigarette smoke, and cleaning supplies ...
Moraxella catarrhalis. 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 ...
Citrobacter koseri. Specialty. Infectious disease. Citrobacter koseri, formerly known as Citrobacter diversus, is a Gram-negative non-spore forming, rod-shaped bacterium. It is a facultative anaerobe capable of aerobic respiration. It is motile via peritrichous flagella. [2] It is a member of the family of Enterobacteriaceae.
Bacterial tracheitis is a rare complication of influenza infection. [4] It is the most serious in young children, possibly because of the relatively small size of the trachea that gets easily blocked by swelling. The most frequent sign is the rapid development of stridor. It is occasionally confused with croup.
