Otomycosis is defined as a fungal infestation of the external ear canal. It is a common complaint in an otolaryngologist’s clinic. Patients with otomycosis usually complain of pruritus, otalgia, decreased hearing & otorrhea with otoscopic findings of small, well-defined areas of granulation tissues with thick fibrinous deposits on the external auditory canal or on the tympanic membrane (1). Lack of cerumen, increased air saturation, heat environment, water sports activity and frequent trauma to the ear canal are contributing factors in development of otomycosis. Cerumen is acidic in nature with a pH of 4 to 5 which does not promote growth of bacteria and fungi. Frequent water exposure of the external ear canal leads to elimination of cerumen and drying of the ear canal (4). Aspergillus niger and Candida albicans are the two most frequent pathogens of otomycosis (5). …show more content…
They can inhabit a wide variety of substrates hence, they are widely distributed, and are found in an extensive array of habitats (6). The genus Aspergillus is the most common cause of otomycosis which comprises approximately 75% of the cases, with Aspergillus niger being the most common species and less common are the Aspergillus flavus and Aspergillus fumigates

The article from the American Academy of Pediatrics (AAP) and American Academy of Family Physicians (AAFP) that addresses acute otitis media (AOM) is a filtered resource. This article is appropriate for use in nursing practice as it establishes diagnosis and management guidelines for the treatment of AOM. In addition the article recommends treatment options for the symptoms of AOM and addresses the concept of watchful waiting. The is an evidence based guideline as it provides recommendations for practice and was created a systematic review and best clinical research in clinical literature.

4. Know the classification of fungal diseases (mycoses). 30% of known fungal species produce mycoses, which are fungal diseases of plants, animals, and humans. Classifications of fungi are; Zygomycota, Ascomycota, and Basidiomycota.
Acute Otitis Media (AOM), inflammation or infection of the middle ear, is an illness most parents have had experience with. Countless hours of lost sleep and worry secondary to their child’s pain and distress can keep even the most seasoned parents awake at night. Before the age of 36 months, 83% of children will experience 1 or more ear infections and AOM is the most common reason for office visits of preschoolers in the United States (Zhou, Shefer, Kong & Nuorti, 2008). The graphic below serves as a review of evidence and explores the usefulness of the information in relation to the option of watchful waiting in the management of AOM.
Otitis Externa is most often caused by Staphylococcus aureus and Pseudomonas aeruginosa. Acute otitis media can be caused by bacterial or viral pathogens. Some of the pathogens associated with acute otitis media (AOM) include, S. pneumoniae, H. influenza, M. catarrhalis, and Streptococcus pyogenes. The common cold or rhinosinusitis is likely caused by rhinoviruses, adenoviruses, coronaviruses, enteroviruses, influenza and parainfluenza viruses, and respiratory syncytial virus (Burns, Dunn, Brady, Starr, & Blosser, 2013). Acute bacterial rhinosinusitis (ABRS) is a result of the S. pneumoniae, H. influenza, M. catarrhalis and/or B-hemolytic streptococci bacterias. Sore throats or acute pharyngitis is 90 percent of the time caused by a viruse. Bacterial sore throats are often a result of the group A streptococci bacteria. According to Burns et al., 2013, Mycoplasma pneumoniae, Chlamydia pneumoniae, groups C and G streptococci, and Arcanobacterium hemolyticum can cause acute pharyngitis. Pathogens that typically cause infections of the tonsils include B-hemolytic streptococci, group D streptococcus, and S. pneumonia (Burns, et al., 2013). The pathogens involved in acute cervical adenitis include B-hemolytic strep, staphylococcus, B. heneslae, viruses, and atypical
External otitis is an infection of the skin covering the outer ear and ear canal. It is also known as swimmers ear. It is most often a bacterial infection caused by the streptococcus, staphylococcus, or pseudomonas bacteria. Acute external otitis is usually caused by excessive water (usually from water sports), trapped in the external ear canal by cerumen. This trapped moisture can cause the skin in the ear canal to become a breeding ground for bacteria. As always, any cuts or abrasions can leave the any part of the body, including the ear canal, susceptible to bacteria and infections. External otitis affects the ear and auditory system. Someone with swimmers ear may first notice that their ear may feel full and itchy. The ear will swell,

ear infections (American Academy of Otolaryngology). There are antibiotics for these diseases, but over the years they have been becoming more resistant.
The patient is an eight-year old girl who is taking hydrocortisone, neomycin, and polymyxin eardrops for the diagnosis of a bacterial ear infection. The dose is 10mg (1%)/3.5mg (0.35%)/10000 units/10ml and was instructed to take this medication every six to eight hours with three drops in the affected ear. The medication has multiple classes since this medication contains multiple drugs. Hydrocortisone is a corticosteroid medication that works to decrease inflammation within the ear. Neomycin and polymyxin are within the antibacterial class and work to combat infection. The combination of the drug helps to eliminate the bacteria within the ear; decrease pain, redness, and itching that were accompanying her bacterial

Otitis externa is cellulites of the external auditory canal. The most common pathogens include, Staphylococcus aureus and Pseudomonas aeruginosa. Bullous myringitis is inflammation of the tympanic membrane; common pathogen is Streptococcus pneumoniae. Acute otitis media in an acute infection of the middle ear; most common pathogen includes S pneumoniae and H influenza (35-45%). The third most pathogen is M catarrhalis (15-18) and the fourth most common pathogen is Streptococcus pyogenes.
When removing this patient’s cerumen, there are two factors that influence my decision to use suction as my method of removal. First of all, his cerumen is soft and near the entrance of the canal, which is ideally removed with suction. Secondly, this patient has diabetes. Diabetic patients’ cerumen has a significantly higher pH than patients without diabetes who have more acidic cerumen. Because of this, using irrigation can lead to external otitis, which can develop into pseudomonas osteomyelitis. To avoid this, it is best to avoid irrigation as a means of cerumen removal in this population.
Otitis externa, is one of the common types of ear infection. The other type of ear infection is otitis media. Both affect the Otolaryngology organ system. Otitis externa is also known as “swimmers ear” and affects the external ear canal. That is why it is called otitis externa, because the affect is to the external air canal. Otitis externa is called swimmers ear because swimmers develop this condition when water settles in the ear and mixes with the cerumen (ear wax). This combination is ideal for bacteria and fungus.
In case of clearly established bacterial infection to otorhinolaryngological evaluation or in the event of persistence of fever with painful symptomatology after the first 72 hours the antibiotic is necessary. Generally they use broad-spectrum antibiotics properly administered daily dose and duration. In the event of repeated infections, and in close suspicion of insufficient efficacy, sensitivity testing provides information useful sull'antibiotico to which the beat is sensitive or sull'antibiotico more effective for therapeutic treatment.
