SEXUALLY TRASMISSITED INFECTION - PowerPoint Presentation

Slide1

SEXUALLY TRASMISSITED INFECTION

DR.WASSAN NORI MOHAMMED

Slide2

In order to assess it is necessary to find out -When sexual intercourse last took place-Whether this was oral, vaginal -What contraception was used?-A travel history and knowledge about the origin of partner might indicate risk of tropical infection.

-Information about previous pregnancies and menstruation

-Mix infection possible so full screen should be performed-To break the chain of infection and prevent re-infection, it is essential to avoids to intercourse until she is that her partners has been screen and received appropriate treatment,fallow up &evalution test of cure

Many gynecological infection are sexually transmissible

Slide3

it is commonest bacterial STD,obligate intracellular bacteria that grows in vitro only in tissue culture infect columnar epithelium of endocervix,urethra, endometrium ,fallopain

tubes and rectum .

This organism can persist for long periods in an asymptomatic carrier state There s no vaccine available and even though chlamydia antibodies are produced, they do not protect against reinfectionCHLAMYDIA TRACHOMATIS

Slide4

1-Asymptomatic in 50% of male 2-Or can cause non- gonococci urethritis in maleIn female

1-Asymptomatic 80%in female

2-Vaginal discharge and lower abdominal pain 3-Postcoital bleeding 4-Intermenstrual bleeding 5-Mucopurulent cervical discharge with contact bleeding 6-Dysuria with urethral dischargeClinical features

Slide5

1-ELISA limited sensitivity samples are collected from the endocervix and areas of cervical ectropian (infect columnar epithelium)2-Nuclic acid amplification technique 90% sensitive should used replace the old ELISA.

3-Aptima

Cmbo 2 and BD probetec are the recommended test for Chlamydia infection Diagnostic test:

Slide6

1- Avoid intercourse before treatment of both partners is complete 2- Use of condoms should be encouraged to prevent reinfection and other STDs 3- Restarting if any doubt about complete treatment 4- Test of cure should be routine in pregnancy

5- Contact tracing of all partners when possible

6- A follow-up interview which could also include a telephone consultation within 2-4weeks 7- Test for other STDs 8-Antibiotic treatment Treatment. ,General advice:

Slide7

Doxycycline 100mg twice for 7daysAzithromycin 1gram orally single dose is recommended during pregnancyAmoxicillin 500mg three times for seven day In

pregnancy can cause

: -PTL-ChorioamnionitisPost partum endometritis-Neonatal conjunctivitis and pneumonia

Slide8

1-Partner of the patient diagnosed or suspected with infection2-History of Chlamydia in the last year 3-Patient attending GUM clinics4-Ptients with two or more partners with in 12monthes5-Women undergoing termination of pregnancy 6-History of other sexually transmitted infection and HIV

Screening and opportunistic testing:

Slide9

It is the 2nd most common bacterial STI Chronic a symptomatic infection is common. It infect columnar epitheliumClinical

features:

1-Most of infected female are asymptomatic 2-Increase vaginal discharge with lower abdominal pain3-dysuria with urethral discharge 4-proctitis with rectal bleeding discharge and pain5-Endometritis6-Mucopurluent urethral discharge7-pelvic tenderness with cervical excitation

GONORRHOEA

Slide10

1-Demonstrating typical gram –ve intracellular diplococcic (columnar cubical epith) on gram stained smear of end cervical and rectal pharynx swabs if symptomatic infection Culture required co2 7%, blood agar antibiotic to inhibit growth of other bacteria(Thayer-Martin or

Transgrow

media culture)2-Nnuclic acidamplificationtest(NAATs)3-Nuclic acid hybridization testsDiagnosis

Slide11

1-Screen both parteners and refer them to genitourinary medicineclinic2-Counselled regarding the long term implicationsof

infection leading to chronic pelvic pain and tubal infection and

subfertilty1-Azithromycin 1g single dose2-Amoxycillin 1g +probencid 2g single dose3-ciprofloxacin 500mg single dose4- single dose cefixime

400mg

Sex partner should screened fully

Treat other associated infection Abstinence during treatment at least 7 days

Treatment:

Slide12

1-Fitz –hugh –curytis syndrome:Intra-abd spread of GC can cause per appendicitis, per hepatitis patient presented with right hypochondria pain tenderness, pyrexia .

Examination: usually sign of

salpingitis, laparoscopy (fine violin string adhesions)seen between the liver capsule and visceral peritoneum ,treatment 3weeks antibiotic per hepatitis cured2-Ritters syndrom or sexually acquired reactive arthritis, uveitis and rash3-PID4-Adult conjunctivitis

COMPLECATIONS OF CHLAMYDIA AND GC

Slide13

Incurable STDHSV1 cused oral lesion (cold sores),30% of genital herps HSV2 cause genital lesion and 90%of recurrent genital

herps

.The ferquency of reurranceis much heigher in type 2 than type 1Infection is frequently sub clinical, presentation can occur many years later as newly acquired infection

HERPS SIMPLEX VIRUS

Slide14

Presents up to 3 weeks after acquisition wide spread lesion involve vulva, vagina ,cx painful vesicles coalesce in to multiple ulcers, per urethral involvement may cause sever pain ,urine retention .Systemic symptoms fever ,

headache ,malaise and lymphadenopathy.

Acute cervicitis may be present. The lesion heal without scarring in 14-21 daysVery early vulvae affect small area, so antiviral treatment for 5 days very early vulvae affect small area, so antiviral treatment for 5days for all patients presenting with the first attack An infected mother can transmit the virus to her infant during delivery resulting in significant fetal mortality and morbidity

PRIMARY HERPS

Slide15

DX1-culture2-virus by electron microscope of the swab taken from the lesion.TREATMENT

1-analgesics

2-bathing in salt and water3-lignocaine gel to sore area, acyclovir 200mg five times for 5 days

Slide16

After primary herpes, virus colonizes the neuron in the dorsal root ganglia establishing latent infection.Ulcer, vesicles in the same area or area supply by the same dermatome

The spectrum of severity varies

1-asymptomatic shedding of virus2-apparently trivial ulcers resembling small abrasion on the vulva,3-locolized clusters of vesicles and ulcers over an area 1-2 cm diameter 4-wide spread or chronic ulceration resembling a primary infection can be seen in pregnant female if a women is immune suppressed, large atypical chronic ulcers may develop5-a herpetic ulcer persisting for more than 1 month in ADIS individual

RECURRENT HERPS

Slide17

Swabbing small ulcer in female if initial swab –ve repeated if ulcer recursTREATMENT of RECURRENT EPISODES

1-attack

will resolve ,washing with salt and water to avoid sexual intercourse until healed.2-frequent recurrences more than 6-8 per year ,long term suppression with acyclovir 400mg twice day, to reduce frequency,but infection can still be transmitted to partner

diagnosis

Slide18

Neurological symptoms tingling sensation)before onset of vesicles and pain in the thigh and perineum ,so episodic treatment for 5days,

Slide20

Provider –applied topical therapy include:10%-20%

podophylin

1-2 per week for 6 weeks 5%has the advantage of self application at home twice per day for 3 days Trichloroacetic acid

80%-90%.

Warts

will recur until the immune response control the growth of virus

Topical

imiquimod

cream 5%

(stimulate local cytokine )may be helpful.

Female with warts are not at increase risk of cancer, screen done every 3years, recent sexual partner should examine for genital warts and other

STI

Surgical therapy:

Visible warts with physical methods ,

crytherapy

,

surgicalexcision,electrocautery,lazervaporization

Immune suppressed patient immune based therapies with

intralesion

TREATMENT

Slide21

is a retrovirus ,single strand of RNA, reverse transcriptase is carried with in the core to enable proviral DNA to be produce in an infected cell .the outer membrane protein gp 120 ,bind to cd4 receptors which are present on Helper lymphocytes macrophages ,dendritic cell and microglial cell.Another viral protein P24 surrounds the RNA and enzymes present with in the core of the virus which enters the cytoplasm of an infected cell the drugs target reverse transcriptase or viral proteases

HIV INFECTION

Slide22

1-antibodies to gp-1202-P24 antigen during seroconversion s detectable3-monitor the disease by measuring the level of CD4 lymphocyte in the peripheral blood.

4-PCR technology we can measure the viral concentration of viral RNA in the plasma high level so rapid disease

diagnosis

Slide23

In developing countries HIV spread through vaginal intercourseIn developed countries through homosexual or I.V .drug user and heterosexualGenital ulcer Chlamydia ,GC ,BV. All risk factor for transmission and acquisition ,so good control of STD should decrease incidence of HIV infection

Transmission

Slide24

the aim of therapy is to reduce the level in the plasma to zero with a combination of antiretroviral agents with each cycle of replication of virus if therapy is effective CD4 lymphocyte count rises progressively and at least partial immune restoration occurs HIV ,infects long lived memory cells, so eradicated and cure is unlikely ever after several years of treatment If

succeful

the immune system improves after a few months These drug have potential interaction withOther drug ,they increase the rate of break down of synthetic estrogen in oral CCPTreatment:

Slide25

1-Hpv infection (genital warts) present despite aggressive surgical treatment ,so any persistent atypical warty lesion of skin or vulva should be biopsied2- HPV can result in ca cx , VIN, cytological of cx should done annually

3-PIDrequires longer courses of antibiotic

4-post partum endometritis is common5-HSV eruption of 2nd genital herpes may become wide spread sever and persist for weeks if not diagnosed and treated genital herpes often present as deep painful ulceration6-Although all HIV infected female are urged to use condoms to prevent them transmitting the infection to others they should also be advised to used a more reliable form of contraception if they do not wish to become pregnant.7-CMV infection reactivation

is transmitted mainly in blood, but also in other body fluids such as saliva, semen and vaginal fluid. Drug users who share needles are at high riskClinical featuresThe HBV has an incubation period of 6 weeks to six monthsHepatitis B is a virus that infects the liver but many people with hepatitis B viral infection have no symptoms.

Hepatitis B Virus

Slide27

HBsAg is not infec¬tious ,HBsAg is detectable in serum in almost all cases of acute and chronic HBV -HBVeAgcan be detected in liver tissue of persons with acute or chronic HBV infect.

HBeAg

is detected in the serum of persons with high virus titers and indicates high infectivity.-The presence of anti-HBs indicates immunity to HBV.)Antibody to HBeAg (anti-HBe) becomes detectable when HBeAg is lost and is associated with low infectivity.- Serumantibody

to

HBcAg

(

IgM

anti-

HBc

) indicates recent infection with HBV

diagnosis

Slide28

Women who screen positive for hepatitis B should be referred to a hepatologist for ongoing monitoring for the long-term consequences of chronic infection, for example hepatocellular carcinoma.

Prevention

: 1-Transmission that can be prevented through vaccination and immunization active vaccine provides ongoing protection from subsequent exposure in the household. 2- women who screen negative her partner positive barrier method should use to provide protection against acquiring the infectionManagement
