Herpes Virus infections

1. Describe dermatitis, diagnostic criteria, and treatment modalities

Dermatitis: Dermatitis, also known as eczema, is an umbrella term for inflammation of the skin. It manifests as red, swollen, and itchy patches. Various types of dermatitis include atopic dermatitis, contact dermatitis, seborrheic dermatitis, and stasis dermatitis.

Diagnostic Criteria:

  • History and Physical Examination: The diagnosis of dermatitis primarily relies on the patient’s medical history and a physical examination. Key questions focus on the onset, duration, location of the rash, associated symptoms (itching, pain), and any potential triggers.
  • Skin Prick Tests or Patch Tests: Used to identify specific allergens in contact dermatitis.
  • Biopsy: In uncertain cases, a skin biopsy might be performed to confirm the diagnosis and exclude other conditions.

Treatment Modalities:

  • Topical Corticosteroids: First-line treatment to reduce inflammation and itching.
  • Emollients and Moisturizers: Used to maintain skin hydration and barrier function.
  • Antihistamines: For relief from itching.
  • Calcineurin Inhibitors: Used for sensitive areas like the face and neck.
  • Phototherapy: Ultraviolet light therapy for severe cases.
  • Avoidance of Triggers: Identifying and avoiding specific allergens or irritants is crucial in managing dermatitis, especially contact dermatitis.

2. Describe the drug therapy for Conjunctivitis and Otitis Media

Conjunctivitis (Pink Eye):

  • Bacterial Conjunctivitis: Treated with antibiotic eye drops or ointments such as erythromycin, polymyxin B/trimethoprim, or fluoroquinolones.
  • Viral Conjunctivitis: No specific antiviral therapy; treatment is supportive, including lubricating eye drops and cold compresses. Antihistamines or mast cell stabilizers can be used for allergic conjunctivitis.
  • Allergic Conjunctivitis: Treated with antihistamines (e.g., olopatadine) or anti-inflammatory eye drops (e.g., ketorolac).

Otitis Media:

  • Acute Otitis Media (AOM): The primary treatment is antibiotics, with amoxicillin being the first-line choice. Alternatives include amoxicillin-clavulanate, cefdinir, or cefuroxime.
  • Chronic Otitis Media with Effusion (OME): Typically does not require antibiotics unless there are signs of acute infection. Management focuses on monitoring and, in some cases, tympanostomy tube placement.
  • Pain Management: Acetaminophen or ibuprofen for pain relief.

3. Discuss Herpes Virus infections, patient presentation, and treatment

Herpes Virus Infections:

  • Herpes Simplex Virus (HSV): Presents as grouped vesicles on an erythematous base. HSV-1 typically causes oral lesions (cold sores), and HSV-2 causes genital lesions.
  • Varicella-Zoster Virus (VZV): Causes chickenpox in primary infection and shingles (herpes zoster) upon reactivation. Shingles presents as a painful, unilateral vesicular rash along a dermatome.

Patient Presentation:

  • HSV: Oral herpes presents with fever, sore throat, and painful blisters around the mouth. Genital herpes presents with fever, malaise, and painful genital lesions.
  • VZV: Chickenpox presents with fever and a generalized itchy vesicular rash. Shingles presents with severe localized pain followed by a vesicular rash.

Treatment:

  • HSV: Antiviral medications such as acyclovir, valacyclovir, and famciclovir reduce the severity and duration of symptoms.
  • VZV: Antivirals like acyclovir and valacyclovir are used for shingles to reduce pain and prevent complications. Pain management for shingles includes analgesics, and in severe cases, corticosteroids.

4. Describe the most common primary bacterial skin infections and the treatment of choice

Primary Bacterial Skin Infections:

  • Impetigo: A highly contagious skin infection caused by Staphylococcus aureus or Streptococcus pyogenes. It presents with honey-colored crusted lesions.
    • Treatment: Topical mupirocin or oral antibiotics like cephalexin for widespread cases.
  • Cellulitis: A deeper infection of the skin and subcutaneous tissues, usually caused by Staphylococcus aureus or Streptococcus pyogenes. It presents as red, hot, swollen, and tender skin.
    • Treatment: Oral or intravenous antibiotics depending on the severity; commonly used antibiotics include cephalexin, dicloxacillin, or clindamycin.
  • Folliculitis: An infection of the hair follicles, often caused by Staphylococcus aureus. It presents as small, red, pus-filled bumps around hair follicles.
    • Treatment: Topical antibiotics like mupirocin or clindamycin, and in more severe cases, oral antibiotics.

These descriptions, diagnostic criteria, and treatments align with the latest clinical guidelines and evidence-based practices in managing common skin, eye, and ear disorders.
