Summary
Otomycosis, a fungal ear infection, commonly causes hearing loss and itching. Topical clotrimazole and salicylic acid are effective treatments, with clotrimazole showing the best resolution rates.
Area of Science:
- Otolaryngology
- Mycology
- Infectious Diseases
Background:
- Otomycosis is a common fungal infection of the external ear canal.
- Understanding its clinical presentation and effective treatments is crucial for patient management.
Purpose of the Study:
- To determine the frequency, clinical presentation, predisposing factors, and treatment outcomes of otomycosis.
- To evaluate the efficacy of topical antifungal agents in treating otomycosis.
Main Methods:
- An observational study involving 180 patients diagnosed with otomycosis.
- Data collected included patient demographics, symptoms, predisposing factors, and response to treatments like 1% clotrimazole and 2% salicylic acid.
Main Results:
- Otomycosis presented most commonly with hearing loss (77.7%), pruritus (68.8%), and otalgia (40%).
- Topical 1% clotrimazole and 2% salicylic acid showed effectiveness, with clotrimazole yielding higher resolution and lower recurrence rates.
- 83% of patients improved with initial treatment, while 17% did not respond.
Conclusions:
- Otomycosis commonly presents with hearing loss, pruritus, otalgia, and otorrhoea.
- Local ear care and antifungal instillation are generally effective, but eradication can be challenging in patients with mastoid cavities or diabetes mellitus.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Toxidromes: Clinical Features
171
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

01:22Microbiome of the Eye
67
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
