Vaginal Infections

Vaginal Infections

• Vaginitis: General inflammation of the vagina.

• Candidiasis (Yeast Infection)

  • Risk Factors: Use of antibiotics, diabetes mellitus, and states of immunosuppression.

  • Symptoms: Intense itching, thick white discharge (often described as cottage cheese-like), and local irritation.

  • Treatment: Antifungals administered either topically or orally. Fluconazole (Diflucan) is commonly used as a single-dose oral therapy.

• Bacterial Vaginosis (BV)

  • Pathophysiology: An overgrowth of "bad" or pathogenic bacteria within the vaginal flora.

  • Symptoms: Thin, gray-white discharge and a characteristically strong fishy odor.

  • Treatment: Antibiotics including Metronidazole (Flagyl) or Clindamycin (available as a cream or gel).

  • Alcohol Warning: Patients must strictly avoid alcohol consumption during and shortly after Metronidazole treatment due to the risk of a severe disulfiram-like reaction.

• Trichomonas

  • Definition: The most common non-viral sexually transmitted infection (STI).

  • Symptoms: Characteristic frothy yellow-green discharge, vaginal itching, dysuria (painful urination), and dyspareunia (painful intercourse).

  • Clinical Presentation: Some patients may remain entirely asymptomatic.

  • Patient Education: Patients must abstain from sexual intercourse until the full course of treatment is complete.

• Natural Defense Mechanisms of the Vagina

  • Acidic Vaginal pH: This environment serves as a primary protection against infection.

  • Lactobacillus acidophilus: A bacterium that helps maintain the healthy acidic environment.

  • Estrogen Role: Supports the acidic environment.

  • Effects of Low Estrogen (e.g., Menopause/Perimenopause): Leads to decreased glycogen and decreased lactic acid, resulting in a less acidic (higher) pH and an increased risk of infection.

Pelvic Inflammatory Disease (PID)

• Infection Progression Pathway:

  1. The cervix becomes infected initially.

  2. The infection spreads to the endometrium, causing endometritis.

  3. The infection spreads to the fallopian tubes, causing salpingitis.

  4. The infection may involve the ovaries, causing oophoritis.

  5. In severe cases, the infection spreads to the pelvic peritoneum and the pelvic vascular system.

• Causes: Gonorrheal and chlamydial organisms are identified as the most common causes.

• Hallmark Symptom: Pelvic or lower abdominal pain, which frequently begins shortly after menstruation.

• Clinical Manifestations: Abnormal vaginal discharge, pain during intercourse (dyspareunia), and fever.

• The Chandelier Sign: A clinical finding of severe pain when the cervix is moved during a bimanual exam; the pain is so intense the patient may "jump upward" toward the chandelier.

• Complications: Peritonitis, chronic pelvic pain, increased risk of ectopic pregnancy, and infertility.

• Treatment: Managed with broad-spectrum antibiotics because PID is typically polymicrobial (caused by multiple types of microbes). Common medications include Ceftriaxone, Doxycycline, and Flagyl (Metronidazole).

Toxic Shock Syndrome (TSS)

• Definition: A life-threatening systemic reaction to bacterial toxins that leads to septic shock.

• Common Cause: Prolonged use of high-absorbency tampons.

• Other Causes: Postsurgical infections, infected wounds or burns, nasal packing, and use of diaphragms or sponges.

• Symptoms: Sudden onset of high fever, hypotension (low blood pressure), a diffuse rash resembling a sunburn, and subsequent skin peeling, particularly on the palms and soles.

• Diagnostics:

  • Cultures: Obtained from the vagina, blood, and urine.

  • Laboratory Findings: Elevated Blood Urea Nitrogen ($\text{BUN}$), elevated creatinine, elevated bilirubin, and a decreased platelet count ($\text{thrombocytopenia}$).

• Medical Management:

  • Administration of IV fluids.

  • Broad-spectrum antibiotics.

  • Vasosuppressors: Used to counteract vasodilation when fluids alone are insufficient to maintain blood pressure, such as Epinephrine and Dopamine.

  • Oxygen therapy.

  • Continuous monitoring for bleeding.

Structural Disorders

• Vaginal Fistulas: Defined as an abnormal opening between two internal structures.

  • Ureterovaginal Fistula: An opening between the ureter and the vagina.

  • Vesicovaginal Fistula: An opening between the bladder and the vagina.

  • Rectovaginal Fistula: An opening between the rectum and the vagina.

  • Assessment Findings: Observation of urine or feces draining from the vagina, skin excoriation (irritation), and infection.

  • Diagnosis: Physical examination or the use of methylene blue dye administered via the bladder, vagina, or IV.

  • Nursing Care: Management of Foley catheters, dietary restrictions (such as a low-fiber diet), and enema preparation prior to surgical repair.

• Pelvic Organ Prolapse: Occurs when pelvic organs descend into or through the vaginal canal due to weakened support structures.

  • Cystocele: The bladder bulges into the anterior vaginal wall, often causing urinary frequency.

  • Rectocele: The rectum bulges into the posterior vaginal wall, causing difficulty with bowel movements.

  • Enterocele: The small intestine bulges into the upper vaginal wall; this is common following a hysterectomy.

  • Common Manifestations: Stress incontinence, feelings of pelvic pressure or fullness, a visible vaginal bulge or protrusion, and cystitis (inflammation of the bladder).

  • Interventions:

    • Anterior/Posterior Colporrhaphy: Surgical repair procedures.

    • Pessaries: Silicone devices inserted into the vagina to provide physical support for pelvic muscles.

    • Kegel Exercises: Pelvic floor muscle training to strengthen support.

Fibroid Tumors (Leiomyomas/Myomas)

• Definition: Non-cancerous muscular tumors that grow within or on the walls of the uterus.

• Characteristics: Most common in women of reproductive age; can be small or large, single or multiple, and are typically slow-growing.

• Symptoms:

  • Many patients are asymptomatic.

  • Menorrhagia: Excessive or heavy menstrual bleeding.

• Treatment Options:

  • Dilation and Curettage (D&C): A surgical procedure where the cervix is dilated and the uterine lining is scraped or suctioned; this helps reduce heavy bleeding but does NOT remove the actual fibroids.

  • Myomectomy: Surgical removal of the fibroids while leaving the uterus intact.

  • Hysterectomy: The definitive treatment involving the complete removal of the uterus.

Endometriosis

• Definition: A chronic condition where tissue similar to the lining of the uterus (endometrial-like tissue) grows outside the uterus, causing inflammation, scarring, and adhesions.

• Common Sites:

  • Ovaries: May form endometriomas, colloquially known as "chocolate cysts."

  • Fallopian Tubes: Leads to scarring and a high risk of infertility.

  • Pelvic Lining: Cited as the most common site of growth.

  • Rare Sites: Can occasionally involve distant organs.

• Symptoms:

  • Cyclical pelvic pain.

  • Dyspareunia: Defined as persistent or recurrent genital pain that occurs before, during, or after sexual intercourse.

  • Pain during urination or defecation.

  • Infertility: Present in $30-50\%$ of women struggling with infertility.

• Causes and Theories:

  • Retrograde Menstruation: Menstrual blood flows back through the fallopian tubes into the pelvic cavity.

  • Immune Dysfunction: The immune system fails to recognize and destroy ectopic endometrial tissue.

  • Genetic Predisposition: A family history of the condition.

• Risk Factors:

  • Early menarche (starting menstruation at a young age).

  • Short menstrual cycles.

  • Long menstrual duration (older individuals).

  • Nulliparity (having never given birth).

• Diagnosis: Definitive diagnosis is made via Laparoscopy and Biopsy.

• Treatment:

  • NSAIDs for pain management.

  • Oral contraceptives to control or stop menstruation.

  • GnRH agonists to suppress the growth of endometrial tissue.

  • Surgical excision to remove adhesions, though this is not considered a permanent cure.

Gynecological Cancers

• Cervical Cancer

  • Risk Factors: Early sexual activity, having multiple sexual partners, Human Papillomavirus (HPV) infection, and chronic cervicitis.

  • Symptoms: Watery, bloody, or foul-smelling vaginal discharge; pelvic or lower abdominal pain; and irregular vaginal bleeding.

  • Diagnosis: Pelvic exam, Pap test, and Biopsy (BX).

• Endometrial Cancer

  • Definition: A malignancy of the uterine lining.

  • Risk Factors: Age greater than $50$, estrogen therapy without accompanying progesterone, early menarche or late menopause, nulliparity, and obesity (as adipose tissue converts androgens into estrogen).

  • Symptoms: Often asymptomatic in early stages. Symptoms include abnormal vaginal discharge, pelvic/abdominal pain, unexplained bleeding, and pressure on the bowel or bladder.

  • Diagnosis: Pelvic exam, Pap smear, and Hysteroscopy.

• Ovarian Cancer

  • Characteristics: Known for high mortality rates because symptoms are often vague until the disease is advanced.

  • Early Symptoms: Lower abdominal discomfort, urinary frequency or urgency, and bloating.

  • Late Symptoms: Ascites (fluid accumulation in the abdomen), weight loss, severe pelvic/abdominal pain, and a palpable pelvic mass.

  • Diagnosis:

    • No routine screening currently exists.

    • CA-125 Tumor Marker: Normal range is generally less than $35\,U/mL$. In advanced cancers, levels may exceed $200\,U/mL$.

  • Treatment: Total hysterectomy or removal of the diseased ovary, and chemotherapy to shrink tumors prior to surgery.
