Question 1: Describe dermatitis, diagnostic criteria, and treatment modalities

Dermatitis Overview: Dermatitis, commonly referred to as eczema, is an inflammatory skin condition characterized by itching, redness, and rash. It’s a multifactorial disorder with various subtypes, including atopic dermatitis, contact dermatitis, seborrheic dermatitis, and nummular dermatitis.

Diagnostic Criteria: Diagnosis involves a comprehensive assessment of clinical history, physical examination, and sometimes additional tests. Key diagnostic criteria include:

Presence of pruritus (itchiness)
Erythema (redness)
Papules, vesicles, or plaques
Lesions located in typical sites
Chronic or recurrent nature of symptoms
Treatment Modalities:

Topical Corticosteroids: First-line treatment for most cases. They help reduce inflammation, itching, and redness. Potency varies based on severity.
Emollients/Moisturizers: Important for maintaining skin barrier function and reducing dryness.
Topical Calcineurin Inhibitors: Used in cases where corticosteroids are not suitable. They reduce inflammation and help with itching.
Systemic Treatment: For severe cases, oral corticosteroids, immunosuppressants, or biologic therapies might be considered.
Avoid Triggers: Identifying and avoiding allergens or irritants that exacerbate symptoms.
Education: Patient education on proper skin care, hygiene, and moisturizer application.
Question 2: Describe the drug therapy for Conjunctivitis and Otitis Media

Conjunctivitis Drug Therapy:

Bacterial Conjunctivitis: Topical antibiotics like fluoroquinolones, aminoglycosides, or macrolides are commonly prescribed.
Viral Conjunctivitis: Supportive care, lubricating eye drops, and cold compresses. Antiviral medications in severe cases caused by herpes simplex virus.
Allergic Conjunctivitis: Antihistamine eye drops and mast cell stabilizers to reduce symptoms.
Otitis Media Drug Therapy:

Acute Otitis Media (AOM): Antibiotics like amoxicillin are the first-line treatment, especially in severe cases or children under 6 months.
Otitis Media with Effusion (OME): Usually managed conservatively, with watchful waiting and addressing underlying causes like allergies or respiratory infections.
Question 3: Discuss Herpes Virus infections, patient presentation, and treatment

Herpes Virus Infections: Herpes viruses include herpes simplex virus (HSV) types 1 and 2, and herpes zoster virus (HZV). They cause a range of infections, including oral and genital herpes, and shingles.

Patient Presentation:

HSV-1 and HSV-2: Painful oral or genital lesions, itching, burning, flu-like symptoms during primary infection, and subsequent recurrent outbreaks.
Herpes Zoster: Painful rash along a dermatome, preceded by tingling or burning sensations, often accompanied by severe pain (post-herpetic neuralgia).
Treatment:

Antiviral Medications: Acyclovir, valacyclovir, and famciclovir are used to manage herpes virus infections. They reduce viral replication and symptom duration.
Pain Management: Analgesics and anti-inflammatory drugs for pain relief, especially in herpes zoster cases.
Preventive Measures: Vaccines are available for herpes zoster (Shingrix) and certain populations at risk of HSV.
Question 4: Describe the most common primary bacterial skin infections and the treatment of choice

Common Bacterial Skin Infections:

Impetigo: Superficial infection caused by Staphylococcus aureus or Streptococcus pyogenes, leading to honey-colored crusted lesions.
Cellulitis: Infection of the deeper skin layers, usually due to S. aureus or Streptococcus spp., presenting as redness, warmth, swelling, and pain.
Treatment of Choice:

Impetigo: Topical antibiotics like mupirocin for limited lesions. Systemic antibiotics like penicillin or cephalosporins for more extensive cases.
Cellulitis: Empiric antibiotic therapy based on the likely causative pathogens, including beta-lactam antibiotics like cephalexin or dicloxacillin.
