absolutists = all about poverty and absolute measures of socioeconomic deprivation
relativists = think about the relative differences and the larger the differences in society the poorer the outcomes for those worse off
spirit level = think health and social problems are worse in unequal rich countries
Which type of behaviour/personality is a risk factor for CHD?
type A - competitive, hostile, impatient
How can personality/behavior be assessed?
questionnaires, self report, structured clinical interview, assess non verbal, answer content, speech, psychomotor
Psychosocial factors that cause CHD?
mental health problems, low control and high demand at work, shift work, lower rank at work, lack of social support
How can depression be measured?
MMPI, beck depression inventory, general health questionnair, spielbergers state anxiety intervention
primary prevention strategies to prevent STIs?
raise awareness, vaccinations, one to one risk reduction discussions (15-20mins structured discussion, based on CBT), pre and post exposure prophylaxis
secondary prevention strategies to prevemt STIs?
easy access to STI/HIV tests/treatments, partner notification, targetted screening, antenatal screening for HIV and pyphilis, national chlamydia screening programme
tertiary prevention for STIs?
anti retrovirals for HIV, prophylactic antibiotic for PCP, acyclovir for suppression of genital herpes
What is the STI/HIV transition model?
R=BCD reproduction rate infectivity rate partners over time duration of infection
What is partner notification?
a public health activity that aims to control infection by identifying key individuals and sexual networks, warn the unsuspecting and attempt to break the chain of infection
Why trace partners for STIs?
break the chain of transmission, prevent reinfection of the index patient, prevent complications of untreated infection
How are partners traced for STIs?
patient referral, provider referral from phone, test, letter, internet sites, visit, conditional or contract referral
emphasis on the patients choice and confidentiality
Partner notification challenges?
hard to reach client group (from phoneless, homeless, floor sleepers, social exclusion, criminal activities, chaotic life, health care is low priority)
How to increase partner notification?
MDT with public health, PCT, infectious diseases, GUM and drug and alcohol advisory, partner notification undertaken by specialist community outreach nurse and drug worked, GUM health adviser provided notification training and support and coordinated notification management

18-28
Where do adults get chlamydia and gonorrhea?
urethra, endocervical canal, rectum, pharynx, conjunctiva
Where can neonates get STI?
conjunctiva
Symptoms of chlamydia and gonorrhea in males?
dysuria and urethral discharge, complications are epididymoorchitis, reactive arthritis
Female complications of STIs?
pelvic inflammatory disease, tubal factor infertility, ectopic pregnancy, chronic pelvic pain, neonatal transmission, opthalmia neonatorum, atypical pneumonia with chlamydia, Fitz high curtis syndrome (peri hepatitis)
Diagnosis of chlamydia?
nuclei acid amplification tests (NAAT), high specificity and sensitivity (but not 100% sensitive so negative test does not mean not infection)
female - endocervical swab, self collected vaginal swab, first void urine
male - first void urine
Aim of community screening for chlamydia?
reduce complications by reducing the prevalence of the asymptomatic infection (an asymptomatic diagnosis does not mean recent partner change)
Treatment of chlamydia?
partner managment, test for other STIs, azithromycin 1g stat or doxycycline 100mgbd for 7 days
Treatment of chlamydia if pregnant?
Erythromycin 500mg bd for 14 days
gonorrhea diagnosis?
microscopy of gram stained smear of genital secretions looking for gram negative diplococci with cytoplasm of polymorphs, male urethra and female endocervix and urethra, culture on selective medium to confirm, sensitivity testing, NAAT
Treatment of gonorrhea?
partner notification, test for other STIs, continuous surveillance of antibotic sensitivity, single dose treatment preferred, with ceftriaxone 500mg IMI with Azithromycin 1g orally stat
Is chlamydia or gonorrhea more associated with a partner change?
gonorrhea and it has more clinical manifestations, whereas chlamydia can be asymptomatic
What organism cause syphilis?
treponema pallidum subspecies pallidum
What are the stages of syphilis?
early - primary, secondary, early latents
late - late latent, CNS, CVS, gummatous
What STIs are gay men more likely to have?
HIV and syphilis
Symptoms of primary syphilis?
primary chancre normally on genital skin, nipple and mouth
intubation is 9-90days, usually 21-35
dusky macule-papule-indurated clean bases non tender ulcer 50% solitary (genital ulcer is syphilis until proved otherwise)
regional nodes 1-2 weeks after
untreated heals without scarring in 4-8weeks
Symptoms of secondary syphilis?
onset 6-8 weeks after infection, may have primary chancre or none, most present with skin rash
mucus membrane lesions, generalised lymphadenopathy, alopecia, hoarseness, bone pain, hepatitis, nephrotic syndrome, deafness, iritis, meningitis, cranial n palsies, constitutional symptoms
What is the transmission of STIs like?
early syphilis - 40-60% of contactable partners are infected (transmission decreases in early latency and after 4 years)
chlamydia - 70%
gonorrhea - 50-90% women, 20-60% male
What causes death in syphilis?
late benign gummatous, neurosyphilis, cardiovascular
Diagnosis of syphilis?
early moist lesions - identify motile spirochetes on went mount using dark ground microscopy
genital ulcer
rash
use serology for diagnosis
