5Cont. Know the treatment of sexual transmitted diseases. Identify the particular nursing care for each disease/problems.Identify the nursing process.Know the preventive measures.
6INTRODUCTIONSexual transmitted infections constituted one of the major health problems facing the world.Over recent years the prevalence of these diseases has increased at alarming rate.Prevalence 1in5 adult , 1in6 teenagers.
7Cont.Some of these infections linked with cervical carcinoma and HIV infection.The factors Increase STDs:Short duration partners relationship.Increase in world population, increase in those at risk.Diverse sexual practices making diagnosis and treatment more complicated.
8Cont. Increase mobility of population(contact tracing more difficult). Incompliance use of barrier methods.Difficulties in relation to control include:Asymptomatic.Long interval between the person becoming infectious and becoming aware of having disease.
9Cont. Some symptoms not related to genitalia. Failure to produce an antibodies response sufficiently to protect against further infection.Poor heath (venereal diseases).High Risk Group:Age (60%).Prostitutes.Homosexual &Bisexual.
10Estimated Burden of STDs in US STD Incidence PrevalenceChlamydia million millionGonorrhea ,Syphilis ,Trichomoniasis 5 millionHSV million millionHPV million millionHepatitis B , ,000HIV , ,000
12How are STDs spread Skin to skin contact. Oral sex, and kissing (herpes, syphilis, gonorrhea, hepatitis B).Anal sex.Sexual intercourse.Drug abuseSharing personal things(towels, shaving instrument).
13How can STDs harm the body By causing:Abnormal discharge.Abscess.Rashes.Blindness.Brain damage.Liver damage.Cancer
14Cont. Pelvic inflammatory disease. Sterility in both. Tubal pregnancy. Miscarriage.Still birth.Premature birth.Deformities(adult, newborns).Death(HIV, hepatitis B, and syphilis).
15PREVENTION In Islamic public health measures: Personal hygiene, marriage, banish with illegal sexual intercourse, religious values.In Bible public health measures are described to control the spread of the diseases (the suggestion of killing all women likely to be source of infection).
16Cont.Know that sexual activity provides potential contact with STDs and precautions reduce risk.Avoid sexual intercourse with man who has discharge.Avoid unsafe sex practices.Use condom un till disease is fully treated.Periodic screening for STDs.Ask for partner’s cooperation.
17CONT Recognize individuals at high risk. When caring for patients use appropriate barrier precautions.Apply all universal precaution when expose to body fluids of high risk.
18Pathological Vaginal Discharges Candidiasis or moniliasis (thrush) :2nd most common STDsCause by; Candida Albicans is yeast – like fungus.The commonest form is vulvitis, often associated with Diabetes & pregnancyThe feature: small sporesOther sites: Nose, mouth, throat, skin and bowel.
19Risk FactorsLower resistance to infection .(immunosuppressant therapy)Lowering of the vaginal PH.(by using antibiotic & combined oral contraceptive pills)Glycoseuria (High in pregnancy).Humidity and poor hygiene.K-Y jelly used for intercourseWomen how use the diaphragm.
20Cont.In men usually sexually transmitted but in women other factors should be consider.Diagnosis:Microscopic test: Gram- positive spores & mycelia can be detected.Swab for culture.
21Signs and Symptoms Incubational period 1-90 days In some women and most men are asymptomatic.Vulval pruritus (increased by warm).Vaginal discharge, white- cottage- cheese-like in consistency, it’s removal from the vaginal wall leaves a raw area Alternatively:Thin, watery or purulent discharge.
22Cont. Dysuria. Dyspareunia. In male small red spots or curd- like plagues.Treatment:100mg clotrimazole pessary for 6 nights & 1%Clotrimazole cream for vulva and perineum 2-3 times daily.
23Cont.Alternatively:1-2 Nystatin pessary (100,000 i.u.) for 14 nights.Nystatin cream (100,000 i.u.) externally 2-4 times dailyFor male:Warm saline wash.Clotrimazol cream.
24Nursing Care Advise: Use cotton underwear. Avoid vaginal contamination after defecation.Use the pessary and cream over same time.Avoid humidityTreatment should continued during menstruation.Change method of contraceptive.Personal hygiene.
25Trichomoniasis (‘Trike’ or T.V.) One of the most commonest sexual transmitted diseases.Causative organism: Trichomonas vaginalis, an oval flagellate protozoon.Transmission: 1- sexual intercourse contaminated towels infects the lower genito-urinary tract.
26Signs & symptoms Some are Asymptomatic. Incubation period 4-21 days. Vaginal discharge:- offensive(fishy smelling).- Watery, yellow-green and frothy.-possibly profuse.Vulval pruritus and inflammation.
27Cont. Dysuria. In men: un common Urethral discharge. Prostatitis(rare).Balanitis(rare).Dyspareunia in both.
28DiagnosisMicroscopic test: the organism and the movement of it’s four flagellate and undulating membrane can be seen.Swab for culture.By examination: running finger along the anterior vaginal wall the examiner may milk discharge from skene’s tubules.
29Treatment400 mg tablets metronidazole twice /day after meals for 5daysDuring pregnancy 1st trimester 100 mg clotrimazole pessary each night for 6 nights with 1% clotrimazole cream 2-3 times daily.Partner should be treated over same period.
30Nursing care Personal hygiene. Avoid alcohol intake during treatment (unpleasant test, gastrointestinal disturbances & giddiness).Intercourse should be avoided un till the swab is negative.Partner should be treated routinely.
31Cont. Chlamydia: Caused by Chlamydia trichomatis. Commonest cause of genital infection in both sexes.Only survive inside the cells of it’s host.More closely resemble a bacteria than virus.High risk group women years age with multiple partner.Those who do not consistently use condoms.
34diagnosis Swab for culture. Direct immuno-fluorescence detect monoclonal antibodies for Chlamydia(expensive).Enzyme-linked immunosorbent assay(ELISA).Treatment:Erythromycin 500 mg 4 times daily for 14 days(in pregnancy)
35Cont. Doxycycline, 100mg, twice/day for 7 days Azithromycin single-doseOflaxacin, 400mg twice/day for 7 days.
36Complications Infertility. Tubal pregnancy. Infection of Bartholin's glands.TrachomaConjunctivitisBlindness.In men:Epididmo-orchitisGonococcus urethritis.
38Virus Infections Herpes Simplex: The prevalence of this disease is rapidly increasing.Three-quarters of adult population have antibodies to this virus, indicating that they have been infectedEpisode may be primary or recurrent.Wide spread on vulva, vagina and cervixCommonly affecting mouth, pharyngeal, nose, genital area.There are 2 types : type 1 (HSV-1), type 11(HSV-11).Causative organism: Herpes virus hominis.
39Signs & Symptoms Incubation period 2-21 days. Painful vesicles develop in to multiple ulcer.Small, irritant blisters on the perineum.Small red painful erosions (the base is not hard).Dysuria (urine irritating sores).Urine retention.Women may experience a purulent vaginal discharge.
41Cont.Psychological distress (contaminated, difficult to initiate future partner relationship, transmitted to the neonate with disastrous consequences).Type 1 oral lesions(cold sores) less common.Type 11 genital lesions.Primary attack 60% of people develop influenza- like symptoms(headache, backache,
42Cont.(muscle pain & pyrexia, painful enlargement of local lymph glands). THENThe virus lies dormant in nerve ganglia.2nd attacks occur in about 70% of people. Occur up to 3 weeks after ecquisition.Recurrences is less frequent, and resolve more rapidly.Sacral nerves may involve.
43DiagnosisTake adequate sexual & travel histories(common in tropical countries).Culture; collecting serum from vesicle with small-gauge needle & syringe or Appling cotton tipped swab to ulcers.Serological test (distinguish b/w type1 & type11, antibodies).
44Treatment:Antiviral treatment: Aciclovir. Valaciclovir, famciclovir 200 mg 5 times/day for 5 days.Aciclovir cream 5% applied to the lesions 5 times /day for 5 days.Topical 5% Idoxuridine 4 times daily for 4 days (inhibits viral replication by altering its DNA therefore not to be used during pregnancy, near to conceive, during lactation).
45Cont. Simple analgesics Local anesthetic (lignocanine gel applied to sore area).Nursing care:Sensitive discussion and counseling are essentialSeveral follow up are needed. Advise patient herpes is likely even if the swab is negative.
46Cont. Return for further culture if any similar lesion occur. Infection control measures when collecting the sample for investigation.Encourage frequent warm saline washes ( 1 teaspoonful salt in 1 paint water) relive pain & prevent 2nd infection.
47Cont.Relive pain by give analgesic, local anesthetic cream, warm salt washes.Exposure to air (speed healing).Patient with recurrent episode not need antiviral treatment just clean lesions with salt and avoid sexual intercourse.
48Cont. Prevention measures: Avoid contact between other people and open or newly healed lesions.Avoid traveling before the lesion healed completely.Avoid using sharing towels(asymptomatic persons).Treat symptomatic partner.
49Cont.Pregnant women with history, vulva & vaginal swab should be taken weekly from 36 weeks gestation.Improvement of lower socio-economic groups.Vaccine.Avoid reactivation by stress, lower resistance to infection, exposure the sites of original lesions to sun light, friction, use poor lubrication)Use sheaths.
50Complications: Risk of cervical carcinoma. (yearly Pap smear test is suggested).Neurological involvement:Septic meningitis.Transverse myelitis.Autonomic neuropathy.
51Cont.Encephalitis.Herpes keratitis- can lead to corneal scarring and blindness particularly treatment use steroid without antiviral.Surgical intervention(C/S).Resolution usually take 1-2 months.
52HARMFUL EFFECTS of HERPES HARMFUL EFFECTS of HERPES
53Venereal Diseases Usually present as vulvas lesions. Include: Syphilis, Gonorrhea, and chancroid.Common in tropical regions.Gonorrhea (Drip or clap):Is a commonest bacterial sexual transmitted infection.3-5 million cases /year.Teenage have the highest rate of occurrence.
54Cont. 60% of females and 20%-40% of male don’t know they are infected. Despite it’s increasing prevalence remains difficult disease to diagnose in women.Causative organism:Neisseria gonorrhea- gram-negative, diplococcal intracellular.Thrive in wet, mucus-lined body area (vagina, rectum, genitourinary, and endo cervix.
55Cont. Incubation period: 3-30 days after contact. Transmission: sexual relationsSigns and symptoms:Asymptomatic 60% (F) and 40% (M) causing silent epidemic.(103 weeks).Thin- watery or milky discharge, may be yellowish or purulent greenish with foul smelling in female.
57Cont. Pain with burning during urination. Frequent urge to urinate. Cramps in lower abdomen in female.Sore throat.Swelling vulva, urethra, and skene’s glands.In male symptoms may only occur in the morning(ignored).
58DiagnosisHigh power microscopic test: Demonstrate gram negative intracellular diplococcus of fresh smear.(triple swabs, urethral, vaginal, cervical).Swab culture.History.Clinical examination.
60HARMFUL EFFECTS OF GONORRHEA Abscess of penis, may rupture and require surgical repairEpididymitis: infection in the sperm-carrying tubes, can lead to sterility (unable to have children)
61Cont. Treatment: May be resistant to antibiotic. Ceftriaxone 125mg im +100mg doxycycline twice/ day for 7 days.Spectinomycin 2g im in single dose. Or ampicillin2-3.5g im.AlternativeOflaxacin 400 mg oral twice/ day for 7 days.
62Cont. Nursing care: Advise: Both sexual partners need treatment over same period.Avoid sexual activityNeed for condom use.Follow up till 2 tests are negative.Personal hygiene.
63Venereal diseases Syphilis (‘pox’- bad blood): There has been a surge in syphilis over the last 5 years. It is a systematic sexual transmitted infection, 50% of people don’t know they have it.The rate 2-8/100,000 population.Risk Factors:Sexual activity.Lower socioeconomic class.Illicit drug use
64Cont. Causative organism: Treponema palidum- spirochaete, can enter skin & mucous membrane.Transmission:1-Direct contact with skin lesions.2-Sexual intercourse. Kissing3- Through the blood.4- Through the placenta.Incubation period:
65Cont. 9-90 days after exposure, (3-4 weeks average) lesions may appear 1 year after exposure.Stages of Syphilis:Primary stage: Chancre is located at the point of entry. Highly infectious dull red or yellowish ulcer with hard base. Pain less, may appear at labia, clitoris, cervix common site, penis, lips, tongue, anus, and rare in vagina.
70Cont. Chancre healed within 1 month, but infection has not ended. Second stage: 6weeks – 6months after chancre disappear. Later last 3-9 monthsAny organ system may be affected.Sign & symptoms: 80% of peopleLow grade Pyrexia.Regional lymph nodes enlarged.
71Cont. malaise, headache. sore throat joint pain. Large genital warts known as condylomata lata.Dull red rashes, non irritant, non vesicular can cover the body, palms and soles. Systemic eruption occur.All sports & ulcers exude infectious serum.
72Cont. Symptoms may disappear without treatment in 23% of people. Some individuals 20-30% experience clinical relapse, lesions reappear.very infectious.hair loss (alopecia), mucous patches on the mucous membrane (tongue, lips, gum and pharynx).
77Cont.Latent stage:During this stage no manifestation of infection only positive syphilis serology..InfectiousInfection can transmitted to partner.It begins after end of secondary stage and my last for a life time.
78CONT.It begins after end of secondary stage and my last for a life time.Divided into : early and late latency.Early latency :1st year after the resolution of p.& 2nd stage lesions.Infectious.Secondary latency: not infectious except pregnant women may transmit infection to her fetus
79tertiary stage Is the destructive stage of the disease . After 5 years if infection untreated, 5% of people affected.Usually are very slowly progressive.Can be life threaten.Non infectiousThe main types are:1 - late benign gummata (large open sores, slow to heal).
83Cont. Meningovascular syphilis with stroke. Tabe dorsalis. General paresis of insane (loss of memory, emotional liability, personal changes, confusion, impaired balance )Joint degeneration.Urinary retention & constipation.
84Cont.Swelling in skin mucous membrane and bone can be marble- size and may ulcerated .Congenital syphilis complications:Due to vertical transmission.-Eighth nerve deafness.-Interstitial keratitis.- Abdominal teeth.-Meningitis, arthritis-Blindness
85Cont. Deformities (face, jaw, nose, leg, head bone Hand, ect.) Hepatomegaly, spleenomegaly.Convulsion.Hydrocephalus.Mental retardation.Miscarriage, still birth.
86Cont.70% of primary & secondary syphilis can not prevented unless the mother treated before 20 weeks gestation.Diagnosis:Dark- field microscopic test demonstrate thin spiral bacterium.Serological test:
88Cont. History and clinical examination (cervical chancre). Treatment: The treatment of choice is penicillin. Variety of regimens is used.Procaine penicillin 1.2mu injection i.m. daily for 12 daysBenzathine pencillin2.4mu injection i.m. repeated after 7days.
89Cont. Doxycycline 100 mg twice/day for 14 days. Erythromycin 500mg four times a day for 14 days.If infection has been more than 1 year treatment for 21 days for penicillin & 28 days for oral regimen.For neurosyphilis : procaine penicillin 2.4mu i.v, combined with probenecid 500mg -4 times/day.
90Cont. Prognosis: VDRL become negative within 2 years. Nursing care: Both partner should be seen by doctor, tested and treated over the same period.Follow instruction exactly for taken medication.Avoid sexual intercourse.Sample for test HIV infection in all patients.
91Cont.Don’t share medication with other the amount given only to cure your infection.Follow up the serological test for 2 years to be sure you are completely free of infection.Penicillin- allergic women skin test should be done.Advise patient that flu-like reaction is not always due to medication reaction but an allergic toxic response to treponemapallidum.
92Hepatitis BThis virus is present in the blood, and body fluid of those who have been infected.300 million people infected world wide.5,000-6,000 death/ year.Transmission:Through blood.Body fluids.Sexual intercourse.
93Cont. Infected needles(drug addicts & tattooed). The most common risk group:Homosexual and heterosexual (30%).Illicit drug use.Prostitutes.Blood and blood products recipients.15-19 age group
94Cont. People with high risk occupation. Signs and symptoms: Incubation period: days after exposure.Occur within month after contact.Some may have mild or not noticeable symptoms.The degree of infectivity is measure by the presence of viral DNA.
95Cont. Fever, achiness, headache, dizziness, nausea. Vomiting, light or grey colored stool, yellow skin and eyes(jaundice).Pain in liver area(under the ribs).Sever attack in pregnant woman.(immunoSuppressed state)Diagnosis:Serological test for HBV antigen.
96Treatment Supportive and symptoms management. Alpha-interferon therapy.Antiviral (Acyclovir, Zidovudine).Immunomodulatory may used such as corticosteroids, interleukin, thymocin.Mothers who develop acute attack during last trimester of pregnancy or HBe Ag is positiveThey are in high infectious stage and babies
97Cont. Need to be treated prophlactically with specific immunoglobulin. Give 1st dose of vaccine within 24 hours after birth, repeated at 1 and 6 months.Neonatal HB is rare, if occur is serious with poor prognosis. Give several dose of immunogolobulin at 1st 6 months of life.
98Nursing careUniversal precautions in relation to blood, body fluids, and procedures.Avoid intrapartum infections.Cord sample may need to be taken to detect the newborn infection state(HBe Ag).Give 1st dose of vaccine within 24 hours.Encourage test and treat the men who are partner .
99cont Proper disposal of waste product and sharps. Proper collection and transport specimen.Staff should be vaccinated.Protect the baby from becoming carrier and long-term danger (hepatocellular carcinoma, chronic hepatitis, and cirrhosis.Preventive method: HBV vaccine 3doses and 1 boosters 1 month apart.
100Cont. Advise breast feeding mothers: carrier can breast feed. Following acute attack start breastfeeding after baby develop a good level of passive immuinty.
101Cont. Complications: Sever liver damage. Cancer of the liver. Cirrhosis of the liver.Chronic asymptomatic carrier state.Death.Abortion, premature labor.Newborn infection un less treated within hours after birth.

May have flu-like symptoms (may be ignored)Fever, night sweats, swollen glands.Loss of appetite, diarrhea, skin rashes.Window period 6-12 weeks or more:Before HIV antibodies are produced person may be infected but their blood test is negative(false negative).
113Cont. Later signs & symptoms: Significant weight loss Lack of resistance to infection.Shortness of breathing and dry cough.Furry white spots in the mouth.Red or purplish spots on the body(Kaposi’s sarcoma).Memory or movement difficulties.Painful peripheral neuropathy.
115Nursing ProcessAssessing: To identify the patient’s health status , actual or potential problems and needsHistory includes: personal data, complain, when condition start, sexual relationship, obstetric and neonatal history ectPhysical examination: describe the appearance and location of discharge, rashes or ulcers, pain, and any complications
116Cont. Correctly record the findings. Identify the problems and needs Develop the goals related to patient’s out come.Nursing diagnosis: Analyzing patient’s data to determine strengths and weakness.
117Cont.Nursing planning/intervention:Described how you carry out the care plan and integrated the doctor prescription with your plan for each nursing diagnosis.Educate patients and their families.On going planning.discharge planning
118Cont.Evaluation:Measure the extent to which the patient achieved out come.Modify the care plan if necessary.Terminate the care plan if fulfill the patient goals and achieve out come.
