Pathophysiology NU545--Unit 3--STDGonorrhea - ANS Caused by Gonococci.PID sterility disseminated infection (which is spread
throughout the bloodstream to the skin, joints, and heart. Infection can be local or systemic.
Gonorrhea - ANS Passes from mother to child across the amniotic membranes, by direct
inoculation with a fetal scalp electrode during labor monitoring or during passage through the
birth canal,
usually manifests as an eye infection and develops 1-12 days after birth. Ophthalmic abx are
not sufficient to prevent infection. Causes corneal ulceration, with profuse yellow or gray
exudate that is following by necrosis, scarring and compromised vision
Syphilis - ANS 4 Stages: 1. primary chance 2. spread to all systems 3. latent min symptoms 4.
tertiary syphilis most severe stage, distraction of bone, skin, and neurological issues; Congenital
syphilis contributes to prematurity of the newborn bone marrow depression, CNS involvement,
renal failure, and intrauterine growth retardation.
Chancroid - ANS 1-14 day incubation period. Women are generally asymptomatic but can have
dysuria, dyspareunia, vaginal discharge, pain on defecation, or rectal bleeding. A
vesiculopustular lesion forms and erodes into soft ulcer with a necrotic base, surrounding
erythema, and a ragged, serpiginous border. Unilateral painful, local lymphadenopathy presents
primarily in men. Inguinal buboes (abscess) develop and fill with exudate. Lesions spread
through autoinoculation.
Granuloma Inguinale (Donovanosis) - ANS Rare in the U.S. -Bacteria are gram negative and
survive within macrophages. Localized nodules coalesce to form granulomas and ulcers on the
penis in men and labia in women. A chronic and progressively destructive bacterial
infection.Disease can spread to bones, joints, and liver. Infection can spread to inguinal area
and produce pseudo buboes.
Bacterial Vaginosis - ANS Overgrowth of anaerobic bacteria, pH rises in vagina, "clue cells" are
found on a wet mount, fishy odor present assoc with PID, chorioamnionitis, preterm labor,
postpartum endometritis; Treatment of males is not recommended.
Bacterial STDs - ANS Gonorrhea, Syphilis, Chancroid, Granuloma Inguinale (Donovanosis),
Bacterial Vaginosis.
Chlamydia - ANS Most common STI in the US; leading cause of infertility; common bacterial
STI in the US; Cause is C. trachomatis; localizes to the epithelial tissue and can spread through
the urogenital tract or pass from the infected mother to NB infant during birth.
, Lymphogranuloma Venereum - ANS Uncommon in US, initially a skin lesion that spreads into
the lymph system, causing inflammation, necrosis, buboes, and abscesses of the inguinal lymph
tissue; Secondary infections: meningitis, pneumonia,
Lymphogranuloma Venereum - ANS Primary Lesions: MALE: penis&scrotum FEMALE: cervix
vaginal wall and labia. Secondary Lesions: inflammation and swelling of the lymph nodes with
formation of large blue buboes that rupture and form draining ulcerative lesions.
Non Gonococcal or non specific urethritis - ANS NGO is associated with heterosexual men,
men of higher socioeconomic status, caused by a VARIETY of microbes. C. Trachomatis is the
most common cause, this disease is also associated with gonorrhea and chlamydial infection
and develops biphasic illness because of the longer incubation.
Chlamydial Infections - ANS Urogenital Infections: Chlamydia
Lymphogranuloma Venereum
Non Gonococcal or non specific urethritis
Genital Herpes - ANS Most common genital ulceration in the US, lesions appear as groups of
vesicles progress to ulceration with pain, lymphadenopathy and fever; HERPES can pass from
mother to unborn fetus, causing spontaneous abortion or prematurity; THREE district
syndromes: a) 1st episode primary infection b) 1st episode non primary infection c) recurrent
infection. Caused by HSV-1 or HSV-2.
HPV - ANS Assoc with cervical dysplasia, cancer, condylomata; HIGH risk strains cause cancer
(not warts); condylomata acuminata (genital warts) are associated with multiple sex partners
and HIGHLY contagious; can be transmitted to infant at birth;most common symptomatic STI.
HR-HPV is a high risk strain precursor to cervical cancer.
Molluscum Contagiosum - ANS benign viral infection of the skin, transmitted skin to skin
contact in children. In adults it tends to occur on genitalia and be transmitted by sexual contact.
Condylomata acuminata - ANS Genital warts which are sexually transmitted and highly
contagious. Velvety cauliflower-like lesions occur in the genital and anal areas, vaginal, and
cervix and are painless. Can be transmitted to infants at birth.
Trichomoniasis - ANS causes vaginitis in women and urethritis in men; WOMEN Vaginal
symptoms range from none to severe; vaginal discharge (copious, frothy, malodorous &
yellow/green to gray/green), internal itching, dysuria, vaginal appearance of erythema and
soreness. Sometimes strawberry spots (small, punctate red marks) are visual. Vaginal pH > 4.2.
MEN asymptomatic.
Scabies - ANS common parasitic infection that can be spread skin to skin contact and sexual
contact, The mites burrow into the skin depositing 2-3 eggs a day. INTENSE PRURITUS, esp at
night.
