Study Notes
Genital Herpes Simplex (Type 2)
- Transmitted primarily through sexual contact.
- Causes lesions in the genital or rectal area.
- Produces vesicles that rupture, encrust, and cause ulcerations.
Genital Herpes Symptoms
- Malaise, fatigue, and pruritus (intense itching) are common symptoms.
- Edematous and erythematous areas on the labia, vulva, penis, or rectum may be present.
- Tender or enlarged lymph nodes in the surrounding area.
- Cervix is a common site for vesicles in women, leading to complaints of pain, burning, and discomfort.
- Penis is the most common site in men.
- Painful urination and difficulty voiding, especially during the first week of infection.
- Flu-like symptoms (headache, fatigue, muscle aches, fever, anorexia) may occur 3-4 days after vesicle eruption.
- Infection typically presents 2-3 weeks after exposure and develops 2 days to 2 weeks after exposure.
Genital Herpes Transmission
- Can occur by direct contact with any open lesion.
- More common during acute illness or infection.
- Severe consequences for pregnant women (miscarriage, premature delivery, fatal to newborn).
- Cesarean section is usually recommended for infected pregnant women to prevent transmission to the baby.
Genital Herpes Prevention
- Condom use during sexual activity, even in the absence of lesions, is crucial.
- Practicing safe sex.
- Good hygiene, including hand washing, to prevent secondary infections.
- Avoiding touching lesions.
Genital Herpes Diagnosis & Treatment
- Diagnosed through cultures.
- No cure; treatment focuses on symptom relief.
- Acyclovir (antiviral medication) can alter the course of the disease, decreasing severity and duration of outbreaks.
- Acyclovir can be administered orally, topically, or intravenously (in severe cases).
- Warm compresses, keeping lesions dry, avoiding direct contact, and loose-fitting underwear can help relieve pain and pruritus.
- Analgesics (Tylenol, NSAIDs, lidocaine) can be used for pain management.
- Teaching patients about preventing spread is a priority.
- Sitz baths are effective for symptom relief.
Genital Herpes Prognosis
- Healing typically occurs within 10-14 days without treatment, and faster with treatment.
- Recurrences are common, with 2 out of 3 people experiencing 1-5 outbreaks annually.
- Triggers include fatigue, illness, emotional distress, and stress.
Genital Herpes Myths & Facts
- Myth: It's impossible to have sex again after having genital herpes.
- Fact: Sexual contact can be resumed, but it's important to avoid contact when symptoms are present.
- Myth: Safer sex barriers are only needed when lesions are present.
- Fact: Safer sex barriers (condoms) should be used at all times because the virus can be transmitted even in the absence of lesions.
- Myth: Cold sores are not associated with genital herpes.
- Fact: Cold sores are caused by herpes simplex virus type 1, and oral-genital sex can transfer the virus, leading to genital herpes.
- Myth: Genital herpes can be transmitted by toilet seats.
- Fact: This is not true. Genital herpes virus is fragile and dies quickly when exposed to air.
Shingles
- Caused by the same virus that causes chickenpox (varicella-zoster virus).
- Virus lies dormant in the body until resistance to infection is lowered.
- Lesions are located along nerve fibers of spinal ganglia, typically affecting one side of the body.
- Occurs in individuals with compromised immune systems (HIV, chemotherapy, aging, stress, other infections).
- Can also be contracted from someone with chickenpox.
Shingles Manifestations
- Severe pain precedes the eruption of vesicles.
- Pain is often described as burning and knife-like.
- Lesions typically occur in the thoracic region but can affect the lower back, lumbar, cervical, and cranial nerves.
- Skin excoriation (scratching) is common due to intense itching.
- Painful condition lasts 7 to 28 days.
Shingles Subjective Findings
- Severe pain on one side of the body.
- Pruritus.
- General malaise and fatigue.
- History of chickenpox or exposure to chickenpox.
Shingles Objective Findings
- Skin exfoliation from scratching.
- Patches of vesicles on erythematous skin, typically following the spinal nerve pathway.
- Tenderness to the touch.
- Frequent requests for analgesics.
Shingles Management
- Diagnosis is made based on physical exam, health history, and culture.
- Management focuses on pain control, pruritus relief, and prevention of complications.
- Steroids (corticosteroids) are used to reduce inflammation and edema.
- Antiviral medication (acyclovir) decreases pain and duration of the virus.
- Lotions, medicated baths, and warm, moist dressings are used to relieve discomfort and pruritus.
- Heat should be avoided as it can increase blood flow and pain.
Shingles Prognosis
- Recovery takes 2-3 weeks, but can last up to 28 days.
- Postherpetic neuralgia (nerve pain) can develop in 20% of patients, lasting for months to years.
- Older adults are more susceptible to complications.
- Complications can include eye complications (leading to blindness), deafness, brain inflammation, and death.
- The virus remains latent in the body and can reactivate later.
- Individuals with shingles can transmit chickenpox to those who have not been vaccinated.
Cellulitis
- Infection of the skin, not contagious but can be spread by direct contact with an open area on an infected person.
- Typically caused by Streptococcus and Staphylococcus bacteria.
- Bacteria enter the body through a break in the skin.
- Often superficial but can spread to deeper tissues and bloodstream, leading to sepsis.
Cellulitis Symptoms
- Edematous (swelling) and erythematous (redness) area of the skin that feels hot and tender.
- Fever, chills, and malaise.
- Pain in the affected area.
- Small red spots.
- Affected area may resemble a "pitted orange peel."
- Enlarged lymph nodes in the affected area.
- Elevated white blood cell count.
Cellulitis Management
- Diagnosed through cultures and sensitivity testing.
- Treatment involves antibiotics (usually penicillin, erythromycin, or cephalosporins) for 10 days.
- Intravenous antibiotics are given for severe infections.
- Wound care includes warm, moist dressings to relieve discomfort, and elevating the affected extremity.
- Analgesics are used to manage pain.
- Monitoring for hydration, nutrition, and superinfection (secondary infection) is important.
- Immediate medical attention is required if red streaks develop, indicating potential sepsis.
Cellulitis Risk Factors
- Diabetes.
- Lymphedema following surgery.
- Malnutrition.
- Substance abuse.
- HIV.
- Chemotherapy treatment.
- Autoimmune diseases (e.g., lupus).
Impetigo Contagiosa
- Bacterial skin infection caused by Staphylococcus or Streptococcus.
- Occurs at any age but is most common in children.
- Begins as macules (flat, discolored areas), which develop into pustules (pus-filled bumps).
- Pustules rupture and form a dried exudate (honey-colored crust).
- Easily removed crust reveals smooth red skin beneath.
- Commonly affects face, hands, arms, and legs.
- Highly contagious and spread by touch, personal articles, and contact with infected individuals.
Impetigo Contagiosa Subjective Findings
- Pruritus.
- Pain.
- Malaise (general discomfort).
- Spreading of the infection.
- Low-grade fever.
Impetigo Contagiosa Objective Findings
- Erythematous (red) and pruritic (itchy) areas.
- Honey-colored crust over lesions.
- Smooth red skin under the crust.
- Leukocytosis (elevated white blood cell count).
- Purulent exudate (pus-filled discharge).
Impetigo Contagiosa Risk Factors:
- Impaired immune response.
- Crowded living conditions.
- Close contact (e.g., sports).
- Contact with someone who has impetigo.
Impetigo Contagiosa Management
- Treatment involves antibiotics (based on culture and sensitivity).
- Antiseptic soaps used to remove crusts.
- Topical antibiotic cream (e.g., Bactroban) is applied after crust removal.
- Earlier treatment with cream is more effective.
- Prevention of glomerulonephritis (kidney disease) is crucial due to potential complications from strep infection.
- Gloves and sterile technique are used when applying topical antibiotics.
- Education regarding preventing the spread of the infection and completing the full course of antibiotics is essential.
Fungal Infections of the Skin
- Commonly referred to as "tinea" infections.
Tinea Capitis (Ringworm of the Scalp)
- Spread through contact with infected articles (combs, brushes, hats).
- Erythematous (red) lesions with pustules around the edges.
- Temporary alopecia (hair loss) in affected areas.
- Diagnosed by examining the hair follicles under ultraviolet light, which causes them to appear blue-green.
- Wood's Lamp can also be used for diagnosis.
Tinea Corporis (Ringworm of the Body)
- Produces flat lesions with a clear center and an erythematous border.
- Found on non-hairy body parts.
- Intense pruritus (itching).
Tinea Cruris (Jock Itch)
- Found in the groin area.
- Brownish-red lesions that migrate or radiate out from the groin.
- Pruritus and skin excoriation (scratching).
Tinea Pedis (Athlete's Foot)
- Most common type of tinea infection.
- Affects the feet, especially between the toes.
- Common in individuals who perspire heavily, especially in enclosed shoes.
- Can be spread through contaminated public areas (bathrooms, swimming pools, locker rooms).
- Causes maceration (softening) of the skin, fissures, and vesicles around the toes.
- Often discolored.
Fungal Infections of the Skin Management
- Treated with topical or oral antifungal medications.
- Topical treatments (e.g., Tinactin, Lotrimin, Desenex) may not penetrate the hair bulb.
- Antifungal soaps and shampoos are recommended.
- Treatment can last 2-6 weeks.
- Protecting the affected area from trauma and irritation is important for faster healing.
