Chapter 7 - Sexually Transmitted and Other Infections Flashcards
Reproductive Tract Infections
Sexually transmitted diseases (STDs)
Sexually transmitted infections (STIs)
Infections or infectious disease syndromes primarily transmitted by close, intimate contact
-Include more than 25 infectious organisms
-Bacteria, viruses, protozoa, and ectoparasites (lice and scabies)
-Cause tremendous human suffering
Most common STIs in women
Chlamydia Gonorrhea Human papillomavirus Herpes simplex virus type 2 Syphilis HIV infection
Primary Prevention
Primary prevention the most effective way of reducing STIs in women
19 million Americans infected yearly-1/2 of them 15-24 yr olds
Secondary Prevention
Prompt diagnosis and treatment can prevent personal complications and transmission to others
Risk Reduction
Knowledge of partner Reduction of the number of partners Low risk sex Avoiding exchange of body fluids Immunization
Risk Reduction Measures
Physical barriers - Condoms
Chemical barriers - Nonoxynol-9
Communication - Expressing feelings and fears, Attention to partner’s response
Vaccination
Chlamydia trachomatis
Most common and fastest spreading STI
Infections often silent and highly destructive
Difficult to diagnose
PID scarring
15-19 yo highest rates of infection
(scarring end up being fertile when trying to get pregnant)
Chlamydia trachomatis Screening and diagnosis
Asymptomatic and pregnant women
DNA probe
Chlamydia trachomatis Management
Doxycycline
Azithromycin
Erythromycin (eye ointment on babies)
Amoxicillin
Chlamydia trachomatis Perinatal transmission
Antibiotic ointment
Gonorrhea
Aerobic gram-negative diplococcus
Oldest communicable disease in the U.S.
Second to chlamydia in reported cases
Highest rates among teenagers, young adults, and African-Americans
Women often asymptomatic
S/S: purulent discharge, menstrual irregularities, pain
Can have rectal gonorrhea
Gonorrhea Screening and diagnosis
CDC recommends screening all women at risk
Testing during first trimester and at 36 weeks of pregnancy
Reportable disease
Gonorrhea Management
Antibiotic therapy: cefixime or ceftriaxone PCN resistance 1 x IM
Treat partner-frequent reinfections
Perinatal complications of gonococcal infection
Miscarriage Preterm labor Premature rupture of membranes Neonatal sepsis Intrauterine growth restriction Postpartum endometritis Maternal postpartum sepsis
Syphilis
Treponema pallidum, a motile spirochete
Earliest described STI
Transmission by entry in subcutaneous tissue through microscopic abrasions that can occur during sexual intercourse
Also transmitted through kissing, biting, or oral-genital sex
Transplacental transmission may occur at any time during pregnancy
(can cure)
Syphilis
Can lead to serious systemic disease and even death
Infection manifests itself in distinct stages
Infection of Syphilis manifests itself in distinct stages
Primary: 5 to 90 days after exposure-chancre, painless papule, erodes to ulcer
Secondary: 6 weeks to 6 months-widespread rash, maculopapular, feel bad, painless, pink-gray, wartlike infectious lesions
Tertiary: develops in one third of women infected
Syphilis Screening and diagnosis
-VDRL, RPR
Pregnant women
Serologic tests
False positives
Syphilis Management
Penicillin
Sexual abstinence during treatment-monthly follow up
Pelvic inflammatory disease (PID)
An infectious process that most commonly involves the fallopian tubes, uterus, and occasionally the ovaries and peritoneal surfaces
Multiple organisms have been found to cause PID
Pelvic inflammatory disease (PID) Increased risk of
Ectopic pregnancy
Infertility
Chronic pelvic pain
Pelvic inflammatory disease (PID) Symptoms
Lower abdominal tenderness, cervical motion tenderness Abx Pain control (very painful to move cervix)
Human papillomavirus (HPV)
Condylomata acuminata
Affects 20 million Americans
Most prevalent viral STI seen in ambulatory health care settings
Previously named genital or venereal warts
More frequent in pregnant women due to immunosupression
