Infectious disease Flashcards
Fine needle vs core needle aspirate?
Fine needle = cytological info
Core needle = histological info*
- done for breast tissue histological analysis for breast lesions
Family hx of breast cancer conditions for referral to secondary care?
BC in first degree male relative!
BC in first degree relative under 40
Bilateral BC in first degree relative under 50
BC in 2 first degree relatives
What is a triple assessment of the breast for BC?
Clinical exam
Mammography
Core needle biopsy
Ductal carcinoma mammogram findings
areas of calcification
which Breast cancer causes pagets disease of breast (eczema like feeling of nipple with lump behind it)
Ductal carcinoma in situ
if someone has HER2 receptor positive breast cancer?
Can treat with a biologic
= trastuzumab
if someone is on trastuzumab for breast cancer what needs to be monitered?
Cardiac function
cardiotoxicity causing drug
TNM for breast cancer?
Small tumours under 2cm in size score T1.
If cancerous cells are found in 4-9 local lymph nodes (axillary or internal mammary), an N2 score is given. If fewer than 4 are affected, then the score is N1. If more than 9, or it has spread to supra- or infra-clavicular lymph nodes, the score will be N3.
If no metastasis is found, the score will be M0. If there is metastasis, the score will be M1.
every px who has a wide local excision of breast cancer should be offered wat?
adjuvant radiotherapy
How does candida albicans affect the skin?
Itchy rash in folds e.g. sub-mammary, groin, axilla
How can a baby get congenital herpes simplex virus?
transmission through vaginal birth within 6 weeks that the mother had infection, mum should do a c section and take intra-partum IV acyclovir
Baby will have vesicular lesions around skin, eyes, oral mucosa, can have encephalititis and sepsis
Most common cause of encephalitis
Herpes simplex virus (1)
Baby with well defined circular papules, target shaped lesions of 3 concentric rings of different colours
starts at palms and spreads out, what is it
Erythema multiforme (allergic reaction to infection), caused by HSV
px has painful ulcers on vulva, but swabs and PCR for HSV are both negative
what next?
probable diagnosis is still genital HSV so
if it is negative PCR and swab (e.g. atypical ulcers) do anti-HSV antibodies to confirm diagnosis
pregnancy and HSV?
Offer patient acyclovir and elective C section
young patient with hx of eczema is pyrexic, fluid filled blisters which break open to leave shallow sores on skin?
Herpes simplex virus caused Eczema herpeticum
an USS of a px showing fluid and air accumulating between fascia in their right thigh?
necrotising fasciitis
How does fourniers gangrene present?
e.g. presented with severe testicular pain, a day ago, dramatically worsened
very unwell, with hx of diabetes/HIV etc
oedematous testicle, erythema with poorly defined margins
palpation impossible due to pain
cremasteric reflex is fine
px with pneumonia and shingles?
Primary HIV infection (leads to recurrent shingles/molluscum contagiosum/pneumocystis jirovecii pneumonia)
hiv diagnosis/screening
combination test
- tests for P24 antigen +
- antibodies against HIV
hiv diagnosis/screening
combination test
- tests for P24 antigen +
- antibodies against HIV
TRALI acute transfusion reaction?
Transfusion related acute lung injury
basically non cardiogenic pulmonary oedema
due to stuff in new blood activating neutrophils in pulmonary vascualture increasing permeability = oedema
TRALI vs TACO?
Transfusion related acute lung injury
vs
Transfusion associated circulatory overload
- too much transfusion in a px with a heart failure causing pulmonary oedema LIKE TRALI except the px will be hypertensive not hypotensive
breast mastitis organisms
Staph A
mastitis risk factors?
Smoking
breast feeding
