What is the most significant risk factor for pelvic inflammatory disease?
A history of prior infection with chlamydia or gonorrhoea is the most significant risk factor for PID
What is the treatment for pelvic inflammatory disease?
Parenteral cephalosporin + Oral doxycyclin
Adjunct metronidazole
Think: Pelvis or vagina can get fungal infections which have spores, so cephalosporin.
You also use your pelvis to ride a bicycle, so doxycycline
Pelvis has a hole, like metronidahole
Which two gastrointestinal infections cause bloody diarrhoea?
Shigella - bloody diarrhoea with vomitting and abdominal pain
Amoebiasis - gradual onset bloody diarrhoea, abdominal pain and tenderness lasting several weeks
Which gastroenteritis presents with a flu-like prodrome, crampy abdo pain, fever and diarrhoea (possibly bloody) and can lead to complications including GBS?
Campylobacter
think: camp = cramp
Which gastroenteritis results in severe dehydration and profuse watery diarrhoea?
Cholera
think: found in the water in poverty, drink water, loose water
Which gastroenteritis results in severe vomiting?
Staph Aureus
think: respiratory pathogen, breath out, vomit out
Which gastroenteritis results in vomiting within 6 hours, diarrhoea after, stereotypically due to rice?
Bacillus cereus
think: basmati bacillus
What antibiotic treatment is recommended for invasive diarrhoea (bloody + fever)?
Ciprofloxacin
think: Cip and Flux, Sip and Flush out that invasive diarrhoea
What antibiotic is recommended for non-invasive / travellers diarrhoea?
Clarithromycin
think: Clear my sins over seas
What is the clinical triad of ARDS?
A - Acute onset
R - Ratio <300 (PaO2/Inspired)
D - Density on CXR of duo-lateral opacities
S - Sepsis is a common cause
What are the most common underlying causes of ARDS?
Sepsis
Aspiration
Pneumonia
Cardinal symptoms of acute pancreatitis?
Sudden onset abdominal pain radiating to the back
Also N&V with anorexia
Tachycardia may result from hypovolaemia.
What investigations may you perform to diagnose coeliacs?
FBC - IDA / folate deficiency
IgA transglutaminase (high titre)
Endomysial Antibody (EMA)
What marker should be investigated to anticipate refeeding syndrome?
Serum phosphate will be low and indicates refeeding syndrome, with the anticipation of a cardiac arrest
What differences in blood test results may be seen in osteomalacia or vitamin D deficiency?
Low Calcium
Low Phosphate
Low Vit D
Raised Alk Phos
Raised PTH
*blood values are normal in osteoporosis
What investigation would you order in suspected myeloma?
What would be the effect on calcium?
Serum electrophoresis and a skeletal survey
Hypercalcaemia
What are some organic causes of osteomalacia?
Vitamin D deficiency Renal failure Liver disease e.g. cirrhosis Drug induced e.g. anticonvulsants Vitamin D resistant; inherited
What are some risk factors and protective factors of ovarian cancer?
Ovarian cancer is hormonal. Ovulation increases Ovarian cancer.
Therefore, early menarche and late menopause, HRT and obesity all increase the risk
Pregnancy and the COCP are both protective
What test is done initially in suspected ovarian cancer?
If raised, what is the next step in management?
CA125
Urgent USS of abdo / pelvis
What is a cause of relative polycythemia?
Dehydration or Diuretics
Plasma volume : Red cell mass
is reduced
What are some secondary causes of polycythemia?
COPD (reduced PaO2 simulates EPO)
Altitude
Obstructive sleep apnoea
Excessive EPO
How may you differentiate true (primary or secondary) and relative polycythemia?
True: Red Cell Mass is >35ml/kg (M) or >32ml/kg (F). Plasma volume remains same giving a true ratio.
Relative: Plasma volume is reduced giving derranged ratio
What is the step-wise management of chronic SIADH?
Fluid restriction
Treat underlying cause
NaCl + Forusemide
Demeclocycline
What is the most common cause of SIADH.
SCLC
