Certainly! Here are the answers to each question based on Module 2 and relevant sources:
### Question 1: Dermatitis
– **Description**: Dermatitis refers to inflammation of the skin that can have various causes, including allergic reactions (contact dermatitis), irritants, or underlying skin conditions.
– **Diagnostic Criteria**: Diagnosis is primarily clinical, involving history-taking, physical examination, and sometimes patch testing for allergens.
– **Treatment Modalities**:
– **Topical Corticosteroids**: First-line treatment for acute dermatitis to reduce inflammation and itching.
– **Emollients**: Moisturizers to maintain skin hydration and barrier function.
– **Avoidance of Triggers**: Identifying and avoiding allergens or irritants that exacerbate dermatitis.
### Question 2: Drug Therapy for Conjunctivitis and Otitis Media
– **Conjunctivitis (Pink Eye)**:
– **Drug Therapy**: Depending on the cause (bacterial, viral, allergic):
– **Bacterial**: Topical antibiotics (e.g., erythromycin, polymyxin B).
– **Viral**: Symptomatic relief with lubricating eye drops; antiviral medications for severe cases (e.g., acyclovir).
– **Allergic**: Antihistamine eye drops (e.g., ketotifen).
– **Otitis Media (Middle Ear Infection)**:
– **Drug Therapy**:
– **Bacterial**: Oral antibiotics (e.g., amoxicillin-clavulanate, cefdinir) for 5-7 days.
– **Pain Relief**: Acetaminophen or ibuprofen for pain and fever management.
– **Antibiotic Ear Drops**: Occasionally used for persistent infections or when oral antibiotics are not feasible.
### Question 3: Herpes Virus Infections
– **Patient Presentation**:
– **Herpes Simplex Virus (HSV)**: Presents with painful vesicular lesions on the skin or mucous membranes, typically recurring in outbreaks.
– **Varicella-Zoster Virus (VZV)**: Causes chickenpox (varicella) initially and shingles (herpes zoster) later in life, characterized by a painful rash.
– **Treatment**:
– **HSV**: Antiviral medications such as acyclovir, valacyclovir, or famciclovir to shorten the duration and severity of outbreaks.
– **VZV**: Antiviral treatment (acyclovir, valacyclovir) for both chickenpox and shingles to reduce symptoms and complications.
### Question 4: Primary Bacterial Skin Infections
– **Description**: Common bacterial infections include:
– **Impetigo**: Superficial infection characterized by honey-colored crusts.
– **Cellulitis**: Deeper skin infection with redness, warmth, and swelling.
– **Folliculitis**: Infection of hair follicles, presenting with pustules or papules.
– **Treatment of Choice**:
– **Impetigo**: Topical antibiotics (e.g., mupirocin) for limited cases; oral antibiotics (e.g., dicloxacillin, cephalexin) for extensive involvement.
– **Cellulitis**: Oral antibiotics (e.g., cephalexin, amoxicillin-clavulanate) covering Staphylococcus aureus and Streptococcus species.
– **Folliculitis**: Mild cases may resolve with topical antibiotics; severe cases may require oral antibiotics.
These answers provide a concise overview of each topic as requested. If you need more details or further clarification on any point, feel free to ask!
