  60. Allopurinol
    • Do not start in acute attack, wait until resolved (usually 1 or 2 weeks later)
    • When starting may trigger gout flares (esp if not titrated up slowly)-consider prophylactic treatment with colchicines 500mcg BD for up to 6 months, if cannot tolerate due to diarrhoea use NSAID with PPI
  61. Atopic eczema
    • Affects 20% children 10%adults Aqueous cream as a soap substitute not as an emollient
    • Continuing the emollient with steroid for flare up increases the efficacy of the steroid, steroid should be applied 30mins after the emollient to aid absorption
  62. Eczema and food allergy

  78. Management of IDA
    Monitor with monthly FBC, and continue treatment until 3m after iron def is corrected.  E.g. ferrous sulphate 200mg BD

    • Follow up with 3 monthly FBCs for one year and a further test after another year. If poor response to iron and Hb not maintained consider ref for further investigations e.g. repeat OGD
  79. Iron deficiency in pregnancy
    • Iron requirements 3x higher in pregnancy
    • Vit Cinc iron absorbption, tea, coffee, wholegrains, calcium and antacids decrease iron absorption when consumed with or after a meal/oral iron

    • Genetic conditions such as FAP and HNPCC
  82. Family history of colorectal cancer-another risk factor what is significant?
    -family history in a first degree relative <45years or in 2 first degree relatives diagnosed at any age gives rise to an increased lifetime risk  reaching 16-25% in men and 10-15% women.

    • -a single first degree relative diagnosed >65 years gives rise to only a slightly increased risk
  83. NICE referral guidelines for suspected cancer 2005

    • >40 with change in bowel habit for 6 weeks
  85. FOB screening
    • England 60-74 offered screening 2 yearly, over 75 can request a test kit
    • Current uptake is 50%

    Sensitivity 55-92% in one study- important to tell patient this is not 100% effective and so to report any bowel symptoms

    May cause distress if falsely positive result and need to warn about complications of colonoscopy if they go on to have this after a positive result

    Reduces mortality from CRC in those screened
  86. Irritable bowel syndrome
    • Affects 5-20%
    • Proposed mechanism- abnml GI motility, enhanced visceral perception, immune activation and altered gut flora as well as psychosocial, genetic and env factors

    Unexplained or unintentional weight loss, rectal bleeding, +FH ovarian/colorectal cancer

    In pt over 60 change in bowels towards loose stools over 6 weeks

    Anaemia, masses (inc rectal- therefore PR recommended), inc inflammatory markers

    Consider OVARIAN pathology in women with new onset IBS like symptoms esp if >50 – do a Ca 125 blood test as this would be raised in ovarian pathology
  89. How to make + diagnosis IBS

    Refer if positive for confirmation of diagnosis with small bowel biopsy
  100. What are the risks of coeliac?
    • Osteoporosis- need bone scan at diagnosis
    •  advice about dietary calcium intake

    Vaccination as 30% have functional hyposplenism- need haemophilus, pneumococcal and annual influenza

    • Advise that risk of malignancy and small bowel lymphoma is greater in coeliacs, absolute risk is small and diminishes with time from diagnosis, autoimmune disease is more common.
  101. Management of coeliac
    Dietitian- for gluten free advice and advice on iron, folate, vit D and calcium

    Annual follow up

    Supply of GF food

  102. Gilberts
    Hereditary – autosomal recessive

    5-10% western populations

    Is due to a genetic variation in the way the pigment bilirubin is metabolised resulting in slightly higher circulating levels than average

    • Reassure not a disease jaundice will resolve in a few days without treatment, does not indicate liver damage

  129. Alcohol in pregnancy
    • Heavy intake-growth restriction and preterm. Binge may affect neurodevelopment. May inc risk of miscarriage
  130. Chronic kidney disease
    All patients should be informed of their diagnosis leading to increased involvement in their care, inc risk of vascular disease
  131. Advise patients CKD
    Adequate hydration, temporary cessation of medications e.g. ACEI/ARB in intercurrent illness, avoid NEPHROTOXIC drugs (NSAIDS),

    care with opiods, hypoglycaemics, digoxin, lithium, high dose statins

    Control BP target <140/90
  132. Interpreting and investigation of proteinuria?
    1.       Check persistent- defined as dip positive proteinuria>2samples, send MSU to ex infection repeat at least 2 wks after uti resolved

    2.       Send urine for albumin:creatinine ratio/protein : creatinine ratio

    • 3.       If confirmed significant proteinuria: do U+E, FBC, ESR, lipids, check USS renal tract, refer nephrology if above referral threshold
  133. Referral threshold for proteinuria?
    ACR >70 or >30 concomitant haematuria 

    PCR>100 or >50 concomitant haematuria
  134. What is the clinical significance of proteinuria?
    Clinically significant proteinuria PCR>30 indicates glomerular rather than tubular pathology e.g. glomerulonephritis+ diabetic retinopathy,

    isolated proteinuria PCR<30 just needs monitoring
  135. Renal USS in CKD when?
    • If patient has obstructive symptoms, FH polycystic kidneys, haematuria, progressive CKD or stages 4
  136. Stages of CKD 1+2
    Stage 1 – kidney damage and normal eGFR (proteinuria, haematuria, anatomical abml) eGFR>90

    Stage2- kidney damage and mild reduction egfr 60-89
  137. stages 3 to 5 CKD?
    • Stage 3a- moderate reduction in egfr 45-59,
    • 3b 30-44

    Stage 4- reduction in gfr 15-29

    Stage 5- established kidney disease.
  138. CKD rate of progression
    • Progressive if rate of decline is greater than average of 5ml/yr over years or >10ml/min over one year
  139. Refer CKD
    If stages 4+5

    • High proteinuria (ACR>70)
    • Proteinuria (ACR>30)with haematuria
    • Rapidly declining egfr (>10ml/min in one year or aveof>5ml/min pa over a few years)
    • Poorly cont HTN despite at least 4 drugs . Or suspected Renal artery stenosis or rare genetic cause of CKD.
  140. CKD when to give ACEI or ARB?
    Diabetes + ACR>30 irrespective BP/egfr

    ACR>70 irrespective of HTN/CVD

    CKD+HTN with clinically sig proteinuria (ACR>30)

    • Use max tolerated dose ACEI check renal function after 1-2w if declines >25% stop + look for cause.
  141. Managing CVD risk in CKD
    Statins if otherwise indicatied e.g. est vascular disease,1prev after SHARP consider

    Antiplatelets for secondary prevention CVD only

    • Identify anaemia if 3b, 4 or 5+ex other cause check haematinics
  142. Bones and CKD
    Check PTH, Ca, Phos only in 4+5

    • Bisphosphonates if indicated ergo/cholecalciferol in stages1-3B, alfacalcidol +ca monitoring stage4 or 5.
  143. Haematuria >+ blood on dipstick what do I do?
    Exclude transient(UTI/exercise) or spurious (menstruation, dietary,sex)cause

    Send MSU to exclude infection

    Persistent- repeat twice more at intervals 2-3 w, if 2/3 positive then manage further ignore’ trace’

    • No UTI but symptomatic? Refer likely urological cause
  144. Assymptomatic NON VISIBLE haematuria (NVH)/microscopic haematuria what do I do?
    Do baseline renal – BP, blood for creatinine eGFR, urine for ACR

    PCR to look for possible glomerular disease-nephropathy and GN
  145. NVH + under 40
    If eGFR<60, urine ACR>30 (PCR>50) or BP >140/90 – REFER NEPHROLOGY

    If normal for primary care monitoring – annual renal function refer if sig change
  146. NVH+ over 40
    • REFER NEPHROLOGY to exclude cancer
  147. Primary care monitoring of continued NVH?
    Annual assessment recommended

    • Refer back to urology if symptomatic/visible
    • Refer nephrology if worsening eGFR >5ml/min/yr or proteinuria
  148. Hypomagnesemia causes
    PPI, antidepressants-citalopram and escitalopram, diuretics

    Hypomagnesemia can cause torsades de points/QT prolongation
  149. Prediabetes study Lancet 2012
    IGT 5-12% will develop diabetes

    • Reduction prog to diabetes after 3 yrs lifestyle intervention by 58% compared to placebo, metformin by 31% compared to
    • placebo

    • 150mins/week aerobic exercise reduces risk by 52%
  150. Prediabetes for patients identified as high risk?
    Offer bloods (fasting gluc/HBa1c) :

    if FBG>7 or hba1c>48(6.5%)repeat tests to look for DM

    FBG 5.5-6.9 Hba1c 42-47 (6-6.4) offer intensive lifestyle programme

    • FBG<5.5 Hba1c <42 reassess risk every 3y
  151. Intensive lifestyle change programme
    • Group based prog min 8 times meet over 18m
    • Focus exercise, weight loss inc whole grains vegetables, reduce fat, annual blds and assessments
  152. Metformin and IGT
    Offer to pts prog to DM despite intensive programme

    Start 500mg daily gradually inc to 1500mg to 2000mg daily

    • Orlistat if BMI>28, 12 w then review need to lose 5% body  weight
  153. Diagnosing DM
    Random FBG>11.1

    Fasting gluc >7

    Plasma gluc >11.1 2hrs after a glucose load 75g in OGTT

    Asymptomatic patients need to repeat to confirm diagnosis.New – Hba1c >48( x2)= correlates with gluc over 3m prev
  154. 2nd line after metformin
    • Used to always use sulphonylurea but evidence to show GLIPTIN good as next step- less risk of hypos and does not affect body weight, expensive though!!
  155. Exentatide/Byetta
    • 3rd line for diabetes for those with BMI>35 or selected BMI<35
    • BD s/c injection
    • SE- N and V
  156. Diabetes
    • EDUCATION and LIFESTYLE- priority – smoking, diet, exercise, nutrition, high fibre, low GI, little sat fat, oily fish, low salt
    • Blood pressure in diabetes
    • Target 140/80, 130/80 if small vessel disease 
  157. Diabetes review things to ask about? 
    • Vision- any vision changes need annual retinal screening, digital images
    • Neuropathic- pain? Rx with TCA/duloxetine
    • Gastroparesis – suspect with unexplained bloating/vomiting-trial of metoclopromide/domperidone
    • ED review annual offer PDE5
    • Foot
    • Screen for depression
  158. Erectile dysfunction
    Affects 30-50%men aged 40 to 70, 80% primarily organic cause, 20% purely psychological

    Maybe the first presentation of vascular disease
  159. Assessment for ED
    • Hx and Ex
    • Examination – check genitals (DRE not essential unless history of LUTs, pain or ejaculatory problems)Blood pressure, weight
  160. Tests for ED
    Serum lipids and fasting glucose in all patients

    All men should have serum testosterone (between 8am and 11am)

    PSA only if clinically indicated but essential prior to commencing testosterone therapy
  161. Management of ED
    Lifestyle advice – some men might want ginseng/yohimbine

    First line PDE5-must receive 8 doses with appropriate advice +sexual stimulation at maximum dose before considered a non-responder.

    Tadalafil licensed at 2.5 and 5mg daily use maybe cost effective if needed >twice/wk

    Vacuum erection device- highly effective but under used 84% satisfaction rates reported

    Second line- intracavernous/intraurethral alprostadil

    3rd line refer for surgical prosthesis
  162. ED caused by hypogonadism
    • If serum total testosterone consistently <12 consider a trial for up to 6m of testosterone replacement, if satisfactory response continue, unsatisfactory- combine with PDE5
  163. Treatment of ED?
    • PDE5 inhibitors- beneficial
    • Alprostadil, intracavernous injection

    • Evidence for ginseng (58% vs placebo 0.5-2g))and yohimbine(30% improved erections in 1 study)
  164. Can I get Viagra on the NHS?
    IF DM, prostate cancer, Parkinsons, MS, prostatectomy, pelvic surgery/injury, RF treated by dialysis or implant, spinal cord injury, may if ‘severe distress’ need specialist input, one per week allowed.
  165. Premature ejaculation
    20-40% prevalence, commonest sexual dysfunction in men, stigma- therefore under-reported and under-treated.

    Definition- ejaculation which always or nearly always occurs within one minute of vaginal penetration associated with negative personal consequences

    Recently tx behavioural strategies and SSRIs

    DAPOXETINE- short acting ssri on demand dosing inc IELT by 3-4min
  166. Causes of premature ejaculation
    Lifelong PE- from first sex ono all attempts of intercourse, genetic basis, neurobiological in cause, ejaculatory control under neuronal control involves neurotransmitters inc 5HT

    Secondary- later in life more likely psychological triggers stress/adv events
  167. Current treatment options for premature ejaculation
    Psychotherapy (couple psychosexual counselling), behavioural methods to improve control

    Topical anaesthetic cream- EMLA prilocaine/lidocaine cream 1st line mx- cause genital numbness  and reduced ability to maintain erection

    • SSRIs- highly effective need to take daily e.g. paroxetine 20-40mg daily, or sertraline, fluoxetine and citalopram-daily initially then to use as needed once ejaculatory control successfully regained/clomipramine if SSRI not tolerated
  168. Restless legs syndrome
    • Ekboms, urge to move your legs
    • difficult to describe sensation
    • crawling/electric/toothache/water running
    • jumpy or twitchy legs, occur every10-60secs
    • typically symptoms occur at rest- particularly sitting/lying
    • worse in evening/sleep
    • eased by walking,moving, shaking, massaging, occ affects arms
    • 1 in10 people
  169. causes of restless legs
    • pregnancy 1 in5
    • lack of iron

    medicines-antidepressants,antipsychotics, dopamine antagonists, antihistamines,calcium channel blockers, antipsychotics,phenytoins or steroids

    As a symptom of other diseases- kidney failure, PD, diabetes, underactive thyroid

    Inv- FBC, iron, UEC

    • general measures- treat cause,  distractions, reading or watching tv if symptoms mild, sleep hygiene
    • reduce caffeine/alcohol
    • salt may affect it

    Exercise during the day 3x per week

    Tx Dopamine agonists- pramipexole, ropinirole, rotigotine,feeling sick,  lightheadedness, lack of sleep, many ppl no side effects. Others carbamazepine, gabapentin, benzodiazepines.
