⚕️FREE MSRA PODCAST –Inflammatory Bowel Disease (IBD)

🎧 A rapid, high-yield breakdown of IBD, focusing on Crohn’s disease and ulcerative colitis – causes,symptoms, diagnosis, and the latest management approaches. Built for effectiveMSRA revision.

🧠Key Learning Points

📌Definition

• IBD is a chronic inflammatory condition of thegastrointestinal tract.

• The two majortypes are Crohn’s disease and Ulcerative Colitis (UC).

• Crohn’s can affectany part of the GI tract (mouth to anus);UC is limited to the colon and rectum.

📌Causes & RiskFactors

• Cause =multifactorial: genetics, environment,and an abnormal immune response to gutflora.

• Revision mnemonic:FGUNU

• F – Family history
• G – Genetic predisposition
• U – Urban living
• N – NSAID use
• U – Unhealthy lifestyle: smoking (↑ Crohn's risk; ↓ UC risk)

📌Pathophysiology

• Immune systemloses tolerance to gut microbes → chronicgut inflammation.

• In Crohn’s: patchy, transmural inflammation.

• In UC: continuous mucosal inflammation starting fromthe rectum.

📌DifferentialDiagnosis

• IBS (IrritableBowel Syndrome)

• Infectious colitis(e.g. Campylobacter, C. diff)

• Coeliac disease

• Colorectal cancer

📌Epidemiology

• ~1 in 250 peoplein the UK

• Affects both sexesequally

• Commonest age atdiagnosis: teens and 20s

• Fluctuatingdisease course with flares and remission

📌Clinical Features

• Crohn’s disease: Abdominal pain, weight loss,diarrhoea (non-bloody), fatigue

• Ulcerative colitis: Bloody diarrhoea, rectalbleeding, urgency, tenesmus

• Systemic signs:Anaemia, malnutrition, fatigue

• Extra-intestinal:Arthritis, uveitis, erythema nodosum, PSC

📌Diagnosis

• Blood tests: FBC, CRP, ESR, LFTs, ferritin

• Stool tests: Faecal calprotectin, stoolcultures

• Endoscopy (colonoscopy ± biopsy): Confirmsdiagnosis and assesses severity

• Imaging: CT or MRI for deeper bowel involvement(esp. in Crohn’s)

📌Management

• Mild UC: 5-ASA (mesalazine)

• Moderate/severe IBD:

• Corticosteroids for induction
• Immunosuppressants: azathioprine, methotrexate
• Biologics: infliximab, adalimumab
  • Lifestyle: Smoking cessation, nutritional support, stress reduction
  • Surgery:
• Indicated in strictures, fistulas, abscesses (Crohn’s)
• Colectomy can be curative in UC

📌Complications

• Crohn’s: Strictures, fistulas, abscesses,perianal disease

• UC: Toxic megacolon, severe bleeding

• Both: Malabsorption, anaemia, increased risk of colorectal cancer (especiallywith pancolitis >10 years)

• Surveillance:Regular colonoscopy for long-standingcolitis

🎧 A clear, high-yield breakdown of this toxin-mediatedantibiotic-associated colitis –perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition

• Overgrowth of Clostridium difficile in the colon →production of toxins A & B → inflammatory diarrhoea ranging from mild tolife-threatening pseudomembranous colitis.

📌 Causes & Risk Factors

• Broad-spectrum antibiotics (esp. cephalosporins, clindamycin,fluoroquinolones)

• Hospital / care-home stay or recent healthcareprocedures

• Older age (> 65 yr)

• Proton-pump inhibitors & H₂ blockers

• Immunosuppression / chemotherapy

• Previous CDIepisode

• GI surgery / tubefeeding

Mnemonic – H-A-P-I GAP

H Hospitalisation A Antibiotics P PPIs I Immunosuppressed G Geriatric A AntecedentCDI P Procedures

📌 Pathophysiology

• Antibioticsdisrupt normal flora → C. difficile spores germinate

• Toxins glucosylateRho-GTPases → cytoskeleton breakdown, apoptosis & leaky mucosa

• Result: waterydiarrhoea, colitis ± toxic megacolon/sepsis

📌 Symptoms

• Watery diarrhoea ≥3 times / day

• Colickylower-abdominal pain & bloating

• Low-grade fever,malaise

• Severe disease:bloody stools, ileus, toxic megacolon

Mnemonic – D-A-M-P

D Diarrhoea AAbdominal pain M Megacolon risk P Pyrexia

📌 Differential Diagnosis

• Viral / bacterialgastroenteritis (norovirus, Salmonella, Campylobacter)

• IBD flare (UC /Crohn’s)

•Antibiotic-associated, non-C-diff diarrhoea

• Ischaemic colitis

• Irritable bowelsyndrome

📌 Diagnosis

• Stool tests: GDH antigen + toxins A/B EIA orPCR for toxin gene

• FBC: leukocytosis;U&E: acute kidney injury; CRP raised

• CT abdomen ifsevere – colitis, megacolon, perforation

Quick memory tip: “GDH + Toxin = Treat; GDH + PCR only? Correlate with symptoms.”

📌 Management

• Stop culprit antibiotic & review PPIs

• First episode (mild–mod): oral vancomycin 125mg QDS × 10 days

• Severe / life-threatening: oral vancomycin + IVmetronidazole; surgical review

• First recurrence (< 12 w): oral fidaxomicin200 mg BD × 10 days

• ≥ 2 recurrences orrefractory — consider faecal microbiotatransplant (FMT)

• Bezlotoxumab IVadjunct in selected high-risk cases

• Infection-control:side-room isolation, gloves & aprons, sporicidal cleaning, hand-washingwith soap (not alcohol gel)

• NICE: severitystratification (WCC, creatinine, fever, colitis imaging) and antimicrobialstewardship to prevent CDI

📌 Complications

• Toxic megacolon& colonic perforation

• Septic shock /multi-organ failure

• Recurrent CDI(20–25 % after 1st episode)

• Dehydration &AKI

📌 Prognosis

Full recovery inmost mild cases; hospital mortality for severe CDI ≈ 5–10 %. Recurrence riskrises with each episode but falls dramatically after successful FMT. Earlydiagnosis, targeted therapy and robust infection control are key to goodoutcomes.

Welcome to anotherhigh-yield deep dive — this time tackling Gastroenteritis,a common and high-stakes topic for bothexams and real-life clinical practice.

🧠 Key Learning Points

📌 Definition

• Gastroenteritis is inflammation of the stomach and intestines, typically due toinfection, leading to diarrhoea, vomiting,abdominal pain, and potentially dehydration.

📌 Causes & Pathogens

• Viruses: Norovirus, Rotavirus (especially inchildren), Adenovirus

• Bacteria: Campylobacter, Salmonella, E. coli O157 (bloody diarrhoea), Shigella

• Toxins: Staph.aureus, Bacillus cereus, Clostridium perfringens

• Parasites: Giardia, Cryptosporidium, Entamoeba

Mnemonic: “NoRotten Apples Scare Every Germy Child” (Norovirus, Rotavirus,Adenovirus, Salmonella, E. coli, Giardia, Campylobacter)

📌 Risk Factors

• Poor sanitation,contaminated food/water

• Acid suppression(e.g. PPIs)

• Immunocompromisedstates

• Vulnerable groups:infants, elderly, immunosuppressed

📌 Pathophysiology

• Pathogens damageintestinal lining → impaired fluid absorption + inflammation → diarrhoea,cramps, and vomiting (via GI irritation or CNS signals)

📌 Differential Diagnoses

• Food poisoning

• Inflammatory boweldisease (Crohn's, UC)

• IBS, appendicitis,viral hepatitis

• UTI, hyperemesisgravidarum, Addison’s disease

• C. difficile,GORD, constipation with overflow

Exam Tip: Vomiting& diarrhoea within hours after food = likely toxin-mediated food poisoning

📌 Epidemiology

• Extremely common:~17 million UK cases/year

• Norovirus → peak in winter; Bacteria → more in summer

• Rotavirus vaccine has reduced severe childhoodcases

• Major cause ofchild mortality in developing nations (due to dehydration)

📌 Symptoms

• Sudden onset diarrhoea, vomiting,nausea, fever,abdominal cramps, loss of appetite

• Watch for dehydration: postural hypotension, dry mouth,oliguria, sunken eyes, poor skin turgor

• Red flags: bloody diarrhoea, confusion,persistent vomiting, signs of sepsis

📌 Diagnosis

• Mostly clinical – based on history + exam

• Stool samples: if symptoms are severe,prolonged, bloody, or if public health concern

• Blood tests: if systemically unwell (checkU&Es, FBC)

• Imaging only ifsuspecting surgical causes

📌 Management

• Mainstay: Rehydration– oral (ORS) or IV fluids

• Antiemetics: cautiously, may aid fluidretention

• Antidiarrhoeals: avoid if invasive bacterialcause suspected

• Antibiotics: only if specificbacterial/parasite confirmed

• Public health: hand hygiene, food safety,isolation 48 hrs post-last symptom

📌 Complications

• Severe dehydration and electrolyte imbalance

• Hemolytic Uremic Syndrome (HUS) – esp. E. coliO157

• Reactive arthritis – e.g. post-Campylobacter

• Guillain-Barré Syndrome – post-Campylobacter

• Toxic megacolon, malnutrition (insevere/prolonged cases)

🎓 Clinical Pearls

• 🚨 Infants, frail elderly, immunocompromised = lower threshold forhospitalisation

• 🌍 Clean water, sanitation & hygiene (WASH) remain critical public health measures globally

• 💡 Safety netting: advise when to seek urgent help (e.g. signs ofdehydration or red flag symptoms)

⚕️FREE MSRA PODCAST –Diverticular Disease (Diverticulosis & Diverticulitis)

🎧 High-yield audio summary covering definition, diagnosis, andmanagement of Diverticular Disease –from asymptomatic pouches to surgical emergencies.

🧠Key Learning Points

📌Definition

• Diverticulosis = presence of colonicdiverticula (pouches), usually asymptomatic

• Diverticular Disease = symptomaticdiverticulosis

• Diverticulitis = inflammation/infection of adiverticulum

🧠Tip: “Osis” =pouches, “Itis” = inflammation

📌Causes & RiskFactors

• Low-fibre diet → hard stools → ↑ intraluminalpressure

• Ageing – most common >50

• Obesity, smoking,sedentary lifestyle

• NSAID use and chronic constipation

🧠Think “LOW-FIBRE +PRESSURE + AGE”

📌Pathophysiology

• Mucosal herniationat weak points (esp. near blood vessels)

• In diverticulitis:blockage by stool (fecalith) → bacterial overgrowth → inflammation/infection

🧠Analogy: Like foodstuck in a pouch → festers → flares up

📌Symptoms

✅Diverticulosis: often asymptomatic or mild LLQ pain, bloating,constipation

✅Diverticulitis: LLQ pain, fever, nausea, vomiting, tenderness, ↑WCC/CRP

✅Diverticular bleeding: sudden, painless PR bleeding,maroon or bright red

🧠Red Flags: Sepsis,peritonitis, recurrent UTI from fistula, palpable mass

📌DifferentialDiagnoses

• IBS, IBD(UC/Crohn’s)

• Gastroenteritis, colorectalcancer, appendicitis, ischaemic colitis, gynaecological causes

🧠Always rule out colorectalcancer if symptomsare unclear

📌Diagnosis &Investigations

• Bloods: FBC, CRP, U&Es, WCC, Anaemia (ifbleeding)

• CT abdomen with contrast = gold standard fordiverticulitis

• Colonoscopy (after acute phase) to excludemalignancy

• Other tools: US,MRI, stool cultures, cystoscopy if fistula suspected

🧠Tip: Avoidcolonoscopy during acute diverticulitis due to perforation risk

📌Management

✅Asymptomaticdiverticulosis: no treatment

✅Uncomplicateddiverticular disease:

 – ↑ dietary fibre,hydration, lifestyle change

 – Bulk-forminglaxatives (e.g., ispaghula husk)

✅Diverticulitis:

 – Mild: oralantibiotics, analgesia, rest

 – Severe: IVantibiotics, fluids, hospital admission

 – Emergency:Surgery if perforation, sepsis, abscess

✅Bleeding:

 – Colonoscopy ±embolisation

 – Surgery ifuncontrolled

🧠Avoid NSAIDs/opioidslong-term; Paracetamol preferred

📌Complications

• Abscess, Peritonitis,Fistulas (colo-vesical, colo-vaginal)

• Bowel obstruction (stricture/scar)

• Hemorrhage

• Chronic strictures or ongoing inflammation

• Rare: potentiallong-term link with colorectal cancer

📌Prognosis &Prevention

• Most withdiverticulosis never develop symptoms

• Recurrence of diverticulitis possible;complications usually with first episode

• Prevention: High-fibre diet, regular exercise,smoking cessation

🧠75% of patients withdiverticulosis stay well

⚕️ FREE MSRA PODCAST – Hepatitis B

🎧 A clear, high-yield breakdown of this DNA viral liver infection with chronic disease risk – perfect for exam prep and real-life clinicalscenarios.

🧠 Key Learning Points

📌 Definition

•Hepatitis B is a DNA virus infection (HBV)that targets the liver and can result in both acuteand chronic liver disease.

📌 Causes & Risk Factors

•Transmission via infected blood, semen, orbodily fluids

•Risk factors:

• Unprotected sex (especially with multiple partners)
• IV drug use (needle sharing)
• Mother-to-child transmission at birth
• Healthcare workers
• Travel to high prevalence areas
  💡 Mnemonic: “BLOOD” – Birth, Lifestyle (sex, drugs), Occupation, Overseas travel, Donor exposure (transfusions)

📌 Pathophysiology

•HBV infects hepatocytes → triggers immuneresponse

•Inflammation damages the liver

•Chronic infection results when immuneclearance is incomplete → fibrosis, cirrhosis, cancer

📌 Symptoms

•Often asymptomatic, especially in acutecases

•If symptomatic: fatigue, malaise, jaundice, RUQ pain, nausea

•Chronic HBV may show non-specificsymptoms or liver decompensation signs in late stages

📌 Differential Diagnosis

•Other viral hepatitis: A, C, D, E

•Autoimmune hepatitis

•Drug-induced liver injury

•Alcoholic liver disease

•Non-alcoholic fatty liver disease

📌 Diagnosis

•Serology panel is key:

• HBsAg: infection (acute/chronic)
• Anti-HBs: immunity
• Anti-HBc IgM: recent infection
• Anti-HBc IgG: past/chronic exposure
• HBeAg: high infectivity
  • Also order: LFTs, coagulation screen, HBV DNA, ultrasound, AFP
  💡 Mnemonic: “SAB Cores and Ends” – Surface Antigen/Antibody, Core IgM/IgG, e-Antigen

📌 Management

•Acute HBV – supportive care, avoidalcohol, rarely antivirals

•Chronic HBV

• Referral to hepatologist
• Antivirals: tenofovir, entecavir, peginterferon
• Monitor LFTs, HBV DNA, liver fibrosis (FibroScan), and screen for HCC
  • Prevent transmission: educate, vaccinate contacts, safe sex advice
  • Pregnancy: treat with tenofovir in 3rd trimester if high viral load; newborns receive vaccine + HBIG
  • Immunosuppression: prophylactic antivirals if HBV DNA >2000 IU/mL
  💡 Treatment depends on phase, HBV DNA level, ALT, and liver damage

📌 Complications

•Cirrhosis

•Hepatocellular carcinoma (HCC)

•Fulminant hepatitis (rare, acute liverfailure)

•Glomerulonephritis, PAN, cryoglobulinaemia

•Hepatorenal syndrome

📌 Prognosis

•Acute infection: usually self-limiting in adults

•Chronic HBV: risk of progression to cirrhosisor HCC

•Monitoring and antiviral treatmentsignificantly improve outcomes

•Vaccine is highly effective – key for prevention

🎧 FREE MSRA PODCAST – Gilbert’s Syndrome: Causes, Diagnosis& Triggers

A subtle yellowtinge in your eyes? Feeling more tired than usual? You might be dealing with Gilbert’s Syndrome, a common and benign condition that often flies under the radar.

This episode unpacksit all in a way that's relevant for exam prep(MSRA) and for patients alike — no fluff, just high-yield clinicalinsight.

🧠 Key Learning Points

📌 Definition

• Gilbert’s Syndromeis a benign inherited condition thatresults in mild, intermittent elevations ofunconjugated bilirubin in the blood.

• It occurs due to reduced activity of the bilirubin-conjugatingenzyme UGT1A1.

📌 Causes

• Genetic mutation in the UGT1A1 gene.

• Leads to reducedactivity (~60–70%) of the enzyme UDP-glucuronosyltransferase,which is responsible for bilirubin conjugation.

• The result: Unconjugated hyperbilirubinaemia — bilirubinthat’s not water-soluble.

📌 Mnemonics

• Gently Yellow – Describes the key sign (mildjaundice) and reminds you the condition is gentle/benign.

• UGT Underperforming – For the gene and enzymeinvolved.

• Reduced Conjugation → Raised Unconjugated Bilirubin– Core mechanism.

• Jaundice flares with FAST STRESS

• F: Fasting
• A: Alcohol
• S: Sickness
• T: Tiredness
• STRESS: Psychological/physical stress

📌 Symptoms

• Often asymptomatic.

• May experience intermittent jaundice (especially scleralicterus), usually triggered by fasting, illness,stress, alcohol, or intense exercise.

• Some report fatigue or mild abdominaldiscomfort, though this isn’t always directly due to the bilirubin rise.

📌 Diagnosis

• Isolated raised unconjugated bilirubin, usually>17 μmol/L but <85 μmol/L.

• Normal liver function tests (LFTs) and normal haemoglobin, reticulocytes, and blood film(to rule out haemolysis).

• Urine tests typically show no bilirubin.

• Genetic testingfor UGT1A1 mutation only if diagnosis unclear.

📌 Differential Diagnosis

• Haemolysis: G6PD deficiency, sickle cell,hereditary spherocytosis, autoimmune haemolytic anaemia

• Liver disease: Hepatitis, cirrhosis,drug-induced hepatotoxicity

• Crigler-Najjar Syndrome (Type I/II) – moresevere enzyme deficiencies

• Drug-induced bilirubin rise: Rifampicin,paracetamol overdose, sulfasalazine

• Other causes: Breast milk jaundice,thyrotoxicosis

📌 Epidemiology

• Affects 3–10% of the UK population

• More common in men and those of Caucasiandescent

• Many remain undiagnosed due to mild or absent symptoms

📌 Management

• No specific treatment is needed – it’s a benign and non-progressivecondition

• Reassurance is key

• Avoid triggers where possible: prolongedfasting, dehydration, overexertion, alcohol

• Encourage a healthy lifestyle with regular meals andhydration

• Awareness ofcondition is helpful if taking medications

Reminder Mnemonic:

Manage Triggers, Maintain Health

📌 Medications to Watch

• Some antivirals: Atazanavir, Indinavir

• Chemo: Irinotecan

• Others: Gemfibrozil, especially with statins

• Always inform healthcare professionals ifdiagnosed with Gilbert’s before starting new medications

📌 Prognosis

• Excellent

• No effect on life expectancy

• No progression to chronic liver disease

• May even have antioxidant benefits (under investigation)

⚕️ FREE MSRA PODCAST – Gastric Ulcer

🎧 A clear, high-yield breakdown of this acid-driven sore in stomach lining – perfect for exam prep and real-life clinicalscenarios.

🧠 Key Learning Points

📌 Definition

•≥ 5 mm breach through gastric mucosa into sub-mucosa caused by loss ofacid–mucosal defence balance.

📌 Causes & Risk Factors

•Helicobacter pylori infection (≈ 70 % ofcases)

•Chronic NSAID / aspirin use

•Cigarette smoking

•Excess alcohol intake

•Corticosteroids ± SSRIs, bisphosphonates

•Severe physiological stress (ICU, burns)

•Increasing age & comorbid cardiac / renal / liver disease

Mnemonic – HANS PAIN

H H. pylori AAlcohol N NSAIDs S Smoking P Physiologicalstress A Ageing I Immunosuppressives/steroids NNicotine (again – double reminder!)

📌 Pathophysiology

•H. pylori urease → ↑ ammonia & inflammation → mucus layer disruption

•NSAIDs ↓ prostaglandins → ↓ mucus, bicarbonate & mucosal blood flow

•Unopposed gastric acid/pepsin → focal necrosis → ulcer crater formation

📌 Symptoms

•Epigastric burning/gnawing pain, often eased briefly by food/antacids

•Early satiety, bloating

•Nausea ± vomiting, haematemesis (coffee-grounds)

•“Black-tar” melena, iron-deficiency anaemia, weight loss

Mnemonic – BURNT

Burning pain Upper-abdomen Relieved by food Nausea/ melena Tired (anaemia)

📌 Differential Diagnosis

•Duodenal ulcer

•GORD / oesophagitis

•Biliary colic, gall-stone disease

•Chronic pancreatitis

•Gastric carcinoma

•Acute coronary syndrome (“indigestion”-like pain)

📌 Diagnosis

•Upper GI endoscopy with multiple biopsies(rule-out malignancy)

•Non-invasive H. pylori tests (¹³C-urea breath or stool antigen)

•FBC for microcytic anaemia; group & save if bleeding

•NICE red-flags → urgent endoscopy (age ≥ 55 + dyspepsia, weight loss, anaemia,dysphagia)

Quick memory tip: “Scope + Bugs = Answer & Cure”.

📌 Management

•Eradicate H. pylori – triple therapy 7days (PPI + clarithromycin + amoxicillin / metronidazole)

•Stop NSAIDs; if essential, co-prescribedaily PPI & consider COX-2 inhibitor

•PPI (e.g. omeprazole 20 mg BD) for 4–8 weeks (longer if complicated)

•Lifestyle: smoking & alcohol cessation, avoid late-night high-fat meals

•Endoscopic haemostasis ± IV PPI for acute bleed (Rockall / Glasgow-Blatchfordrisk)

•Surgery or interventional radiology for refractory bleeding / perforation

•NICE UK priorities: test-and-treat H.pylori in dyspepsia, confirm ulcer healing endoscopically, repeat breath test 4weeks post-therapy.

📌 Complications

•Upper GI haemorrhage (most common)

•Perforation → peritonitis

•Gastric outlet obstruction (pyloric scarring)

•Recurrent ulceration

•Long-term ↑ risk of gastric adenocarcinoma if H. pylori persists

📌 Prognosis

95% heal with successful H. pylori eradication ± PPI. Recurrence low if causeremoved; rises markedly with ongoing NSAID use or smoking. Mortality frombleeding/perforation ≤ 10 % with prompt endoscopic therapy.

🎧 A clear, high-yield breakdown of this common but often late-detected malignancy – perfect for exam prep and real-life clinicalscenarios.

🧠 Key Learning Points

📌 Definition

•Gastric cancer (stomach cancer) is a malignanttumour of the stomach lining, most often arising from the mucosa, with potential for local invasion and metastasis.

📌 Causes & Risk Factors

•Helicobacter pylori infection – majormodifiable risk

•Chronic atrophic gastritis

•Diet: high salt, smoked/preserved foods,nitrates

•Smoking – linked to ~20% of cases

•Alcohol – especially high daily intake

•Age >55, male gender, low socioeconomicstatus

•Genetics – family history, CDH1 mutation (E-cadherin)

•Medical conditions: pernicious anaemia,post-gastrectomy, Menetrier’s disease

•Blood group A, obesity, chemical exposure

Mnemonic: “AGASHDS FMBHA” – Age, Gender, Access (SES), Salt (diet), H. pylori, Drugs(smoking/alcohol), Surgery (post-gastrectomy), Family history, Medicalconditions, Blood group A, Hypogammaglobulinaemia, Alcohol

📌 Pathophysiology

•Chronic inflammation from H. pylori →cellular mutations

•Disruption of DNA control mechanisms → unregulatedgrowth

•Local invasion → lymph nodes → distant metastases (liver, lungs, peritoneum)

📌 Symptoms

•Often asymptomatic early on

•Later: weight loss, abdominal pain, earlysatiety, dysphagia, nausea, vomiting (± blood), anorexia

•Alarm signs: Virchow’s node, Sister Mary Joseph nodule, jaundice, ascites,anaemia

Mnemonic: “PAIN-DAY-FEW”– Pain, Appetite loss, Indigestion, Nausea, Dysphagia, Anaemia, Vomiting, Earlysatiety, Weight loss

📌 Differential Diagnosis

•Gastritis

•Peptic ulcer disease

•Gastro-oesophageal reflux

•Pancreatic or oesophageal cancer

•Functional dyspepsia

•Anorexia or anaemia from other causes

📌 Diagnosis

•Endoscopy with biopsy = gold standard

•CT chest/abdomen/pelvis → staging

•Endoscopic ultrasound (EUS) for local invasion

•Bloods: FBC (anaemia), LFTs, tumour markers (e.g. CEA, CA19-9)

•Consider PET, MRI, laparoscopy in selected cases

📌 Management

•Curative intent:

• Surgery: subtotal or total gastrectomy + D2 lymphadenectomy
• Perioperative chemotherapy: e.g. 5-FU-based
• Trastuzumab for HER2-positive cases
  • Palliative care:
• Chemotherapy/radiotherapy
• Stenting (gastric outlet obstruction), transfusions
• Nivolumab + chemo for PD-L1 positive advanced cancers
  • Supportive: appetite stimulants, pain control, antiemetics
  • Endoscopic mucosal resection (EMR) for early lesions

📌 Complications

•Metastases – liver, lungs, peritoneum

•GI bleeding, obstruction, malnutrition

•Post-op complications (e.g. dumping syndrome)

•Chemo/radio side effects – fatigue, cytopenias, nausea

📌 Prognosis

•Highly dependent on stage at diagnosis

•UK 5-year survival ~20%; Japan >50% (due to screening)

•Early diagnosis = better outcomes

•Late stage → poor prognosis due to spread and treatment limitations

⚕️FREE MSRA PODCAST –Gallbladder Cancer

🎧 A clear, high-yield breakdown of this rare but aggressive biliary tractmalignancy – perfect for exam prep andreal-life clinical scenarios.

🧠Key Learning Points

📌Definition

• Gallbladder canceris a malignancy arising from the epitheliallining of the gallbladder.

• Around 90% are adenocarcinomas.

📌Causes & RiskFactors

• Chronic gallstones(cholelithiasis)

• Chroniccholecystitis

• Porcelaingallbladder (calcification of the wall)

• Primary sclerosingcholangitis (PSC)

• Geneticpredisposition: Lynch syndrome, FAP

• Female sex, age>60

• Obesity, diabetes,high-fat diet

💡Mnemonic:"Go-FOLD" – Gallstones, Older age, Female, Obesity/diabetes, Lifestyle/Inflammation, DNA (genetics)

📌Pathophysiology

• Chronic irritationleads to dysplasia, which progresses to invasive carcinoma.

• Spreads locally tothe liver, bile ducts, duodenum, andlater metastasises to distant sites.

📌Symptoms

• Often asymptomaticin early stages

• Vague abdominalpain (RUQ), indigestion

• Late symptoms:jaundice, anorexia, weight loss, vomiting

• Advanced cases:palpable mass, hepatomegaly

📌DifferentialDiagnosis

• Gallstones(cholelithiasis)

• Cholecystitis(acute or chronic)

• Gallbladder polyps

• Cholangiocarcinoma

• Biliaryobstruction due to infection or stones

📌Diagnosis

• Ultrasound – first-line to identify gallbladderabnormalities

• CT/MRI – staging and spread

• MRCP / EUS – detailed biliary tract imaging

• ERCP with biopsy – confirm malignancy

• Percutaneous biopsy if required

💡Visualise(US/CT/MRI), then Verify (biopsy)

📌Management

• Surgery is the only potential cure

• Simple cholecystectomy for very early disease
• Extended cholecystectomy (includes liver tissue and lymph nodes) for most cases
  • Palliative care if inoperable
• Biliary stenting to relieve obstruction
  • Adjuvant chemotherapy/radiotherapy – especially if positive margins or nodal disease
  💡 Early stage = curative intent; late stage = symptom control

📌Complications

• Local invasion(bile ducts, liver, duodenum)

• Distant metastasis(liver, peritoneum, lungs)

• Biliaryobstruction → jaundice

• Liver failure

• Post-opcomplications: bleeding, infection

•Chemotherapy/radiotherapy side effects

📌Prognosis

• Late diagnosis = poor prognosis

• Advanced disease5-year survival: 5–10%

• Early resectablecases: much better outcomes

• Key prognosticfactors: stage, resection margins, nodal involvement, response to adjuvanttherapy

⚕️FREE MSRA PODCAST –Coeliac Disease

🎧 A clear, high-yield breakdown of this autoimmune gluten-triggeredenteropathy – perfect for exam prepand real-life clinical scenarios.

🧠Key Learning Points

📌Definition

• Coeliac Disease isa chronic autoimmune condition triggeredby gluten, where ingestion leads to immune-mediated damage of the smallintestinal lining, resulting in malabsorptionand systemic complications.

📌Causes & RiskFactors

• Geneticpredisposition: HLA-DQ2 (95%), HLA-DQ8 (80%)

• Environmentaltrigger: gluten ingestion

• Family history(1st-degree relatives)

• Associatedautoimmune diseases: Type 1 diabetes,autoimmune thyroid disease

• Genetic syndromes:Down’s syndrome, Turner’s syndrome

🧠Mnemonic: “GAF-T” – Gluten, Autoimmune, Family, Trisomies/Turner

📌Pathophysiology

• Gluten ingestion →abnormal immune response → villous atrophy

• Key antibodies: anti-TTG (IgA), EMA,deamidated gliadin peptide (DGP)

• Leads to reduced nutrient absorption

• Inflammatory andimmune-mediated damage driven by T-cells

📌Symptoms

• Diarrhoea,bloating, abdominal pain

• Fatigue

• Iron-deficiencyanaemia

• Weight loss

• Dermatitisherpetiformis

• Neurologicalsymptoms: tingling, ataxia

• In children:faltering growth, delayed puberty

🧠Mnemonic: “DIGEST-FATIN” – Diarrhoea, Iron-deficiency, GI symptoms, Energylow, Stomach pain, Tiredness, Faltering growth, Anaemia, Tingling, Neurology

📌DifferentialDiagnosis

• Inflammatory BowelDisease (Crohn’s, UC)

• IBS

• Lactoseintolerance

• Non-coeliac glutensensitivity

• Tropical sprue

• Intestinalinfections

📌Diagnosis

• Serology: Anti-TTG (IgA), EMA – first-line

• Check total IgAlevels – if deficient, use IgG-based tests(e.g. IgG-DGP)

• Small bowel biopsy (duodenum): confirms villous atrophy, crypthyperplasia, intraepithelial lymphocytes

• HLA-DQ2/DQ8 testing: useful to exclude diagnosis

• Biopsy-freediagnosis possible in some adults with strong serology

🧠Tip: Must remain on a gluten-containing diet untilbiopsy is done

📌Management

• Lifelong strict gluten-free diet – cornerstoneof treatment

• Support from dietitians and patientgroups (e.g. Coeliac UK)

• Nutritionalsupplements (iron, folate, calcium, vitamin D) as needed

• Monitor forcomplications and dietary adherence

• Annual review:symptom check, bloods (FBC, LFTs, vitamins), consider DEXA scan

• Refractory CoeliacDisease → specialist referral ± immunosuppressive therapy

📌Complications

• Nutritionaldeficiencies (iron, folate, B12, vitamin D)

• Osteoporosis, osteomalacia

• Infertility

• Increased risk of GI malignancies (e.g.enteropathy-associated T-cell lymphoma)

• Neurological symptoms, splenic dysfunction,dermatitis herpetiformis

🧠Mnemonic: “BONES CAN FAIL” – Bones (osteoporosis), Cancer, Anaemia,Neurology, Endocrine, Skin/Spleen

📌Prognosis

• Excellent withstrict gluten-free diet – symptoms resolve and gut heals

• Risk ofcomplications is significantly reduced with good adherence

• Non-adherenceleads to ongoing symptoms, nutritional deficits, and increased malignancy risk
