Several types of dermatitis exist, each with its own cause:

• Atopic dermatitis: This chronic, inflammatory skin condition often starts in early childhood and is linked to allergies [1].
• Contact dermatitis: This arises from direct contact with irritants (irritant contact dermatitis) or allergens (allergic contact dermatitis) [2].
• Seborrheic dermatitis: This condition affects areas rich in oil glands, such as the scalp and eyebrows, and can cause redness, flaking, and itching [2].

Diagnosis of Dermatitis:

Dermatitis diagnosis typically involves a physical examination of the affected area. Doctors may inquire about the patient's medical history, potential allergens, and lifestyle habits. In some cases, additional tests like skin patch testing might be necessary to identify specific allergens in contact dermatitis [2].

Treatment of Dermatitis:

Treatment for dermatitis depends on the type and severity. Common approaches include [1, 2]:

• Moisturizers: These help hydrate dry, itchy skin.
• Corticosteroids: Topical corticosteroids reduce inflammation and itching.
• Immunomodulators: In severe cases, medications like tacrolimus or pimecrolimus might be used.
• Allergen avoidance: Identifying and avoiding triggers is crucial for managing allergic dermatitis.

Conjunctivitis and Otitis Media: Drug Therapy

Conjunctivitis:

Conjunctivitis, or pink eye, is inflammation of the conjunctiva, the thin membrane lining the eyelids and covering the eyeball. It can have various causes, including viruses, bacteria, allergies, and irritants. Treatment depends on the cause:

• Viral Conjunctivitis: Viral conjunctivitis is highly contagious but usually resolves on its own within a week. Artificial tears might be used for symptom relief [3].
• Bacterial Conjunctivitis: This type may require antibiotic eye drops like erythromycin or ophthalmic gentamicin [3].
• Allergic Conjunctivitis: Antihistamine eye drops like olopatadine or ketotifen can help manage symptoms [3].

Otitis Media:

Otitis media refers to inflammation of the middle ear. It is a common childhood illness often caused by bacterial infections. Treatment typically involves antibiotics, such as amoxicillin or amoxicillin-clavulanate [4]. Pain relievers like acetaminophen or ibuprofen can help manage discomfort [4].

Herpes Virus Infections

Herpes viruses are a group of viruses that can cause various infections, including:

• Herpes simplex virus (HSV): HSV-1 typically causes cold sores around the mouth, while HSV-2 causes genital herpes [5]. Symptoms include blisters, itching, and burning. Antiviral medications like acyclovir can shorten the duration and severity of outbreaks but don't offer a cure [5].
• Varicella-zoster virus (VZV): VZV causes chickenpox in children and shingles in adults. The initial infection with VZV results in chickenpox, characterized by an itchy rash of fluid-filled blisters. Shingles arises from the reactivation of the virus and manifests as a painful rash along a nerve pathway [6]. Antiviral medications like acyclovir can help alleviate symptoms of both chickenpox and shingles [6].

Patient Presentation and Treatment of Herpes Infections:

The presentation of herpes infections varies depending on the specific virus and the location of the infection. Common symptoms include:

• Blisters or sores
• Pain
• Burning
• Itching

Treatment for herpes infections focuses on managing symptoms and reducing the duration of outbreaks. Antiviral medications are the mainstay of treatment, but lifestyle modifications like stress management and avoiding triggers can also be helpful [5, 6].

Primary Bacterial Skin Infections: Treatment of Choice

Several bacterial infections can affect the skin. Here are some common types and their treatment approaches:

• Impetigo: This highly contagious bacterial infection causes red, crusty sores, typically on the face, arms, and legs. Topical antibiotics like mupirocin or oral antibiotics like cephalexin are commonly used for treatment [7].
• Boils and carbuncles: These are localized collections of pus caused by bacterial infections. Treatment involves draining the pus and
