🎧 MSRA Podcast: Anterior Uveitis (Iritis) – Red Eye, Real Risk
A focused Deep Dive into anterior uveitis, the most common uveitis type in the UK. Perfect for MSRA revision, GP triage, or acute red eye cases.

🧠 What You’ll Learn
✅ Definition
• Inflammation of the anterior uveal tract (iris + ciliary body)
• Presents with unilateral red eye, photophobia, pain
• May be granulomatous (chronic/systemic) or non-granulomatous (acute/idiopathic)
🧠 Mnemonic: Mutton fat KPs → think systemic disease

⚠️ Key Associations
• Strong links: HLA-B27 (Ankylosing Spondylitis, Psoriatic Arthritis, IBD, Reactive Arthritis)
• Other: Sarcoidosis, Behçet’s, JIA, Herpes simplex, CMV, Syphilis, TB
🧠 Mnemonic: A-I-I-I – Autoimmune, Infectious, Iatrogenic, Idiopathic

🔬 Pathophysiology
• Immune-mediated, often due to molecular mimicry
• Triggers cytokine release → keratic precipitates, synechiae, flare, hypopyon

🔍 Differential Diagnosis
• Conjunctivitis, scleritis, acute glaucoma, herpes keratitis (no steroids!)
• Other uveitis types, trauma, lens-induced inflammation
🚨 Red flag: Dendritic ulcer on slit lamp = avoid steroids!

📊 Epidemiology
• Most common uveitis in the UK (25–50/100,000/year)
• Peaks age 20–50, slight male predominance (HLA-B27)
• JIA-related uveitis may be asymptomatic – screen regularly

👁️ Clinical Features
• Unilateral red eye, photophobia, blurred vision, lacrimation
• Miotic, irregular pupil, ciliary flush, hypopyon, keratic precipitates
🧠 Mnemonic: RIPP – Red eye, Irregular pupil, Photophobia, Pain

🧪 Diagnosis & Investigations
• Slit lamp: cells + flare in anterior chamber
• IOP may be low or high
• OCT: for macular oedema
• Investigate if recurrent, bilateral, granulomatous, or systemic symptoms
• Bloods: FBC, ESR, ACE, HLA-B27, ANA, RF, Syphilis, TB
• Imaging: CXR (sarcoidosis/TB)
• Infectious screen: HSV, CMV, VZV, toxoplasmosis, Lyme, HIV

💊 Management
• Urgent ophthalmology referral within 24 hours
• Cycloplegic drops (e.g. atropine) – relieve pain, prevent synechiae
• Topical corticosteroids (e.g. prednisolone) – reduce inflammation
❌ Do not start steroids in primary care unless advised
• If infectious: add antivirals/antibiotics
• Systemic immunosuppressants for chronic/refractory cases
• Monitor for glaucoma, macular oedema, cataracts with OCT + exams

📉 Prognosis
• Good with prompt treatment
• Risk of relapse, esp. in HLA-B27
• Chronic cases = higher risk of complications

🚨 Complications
• Glaucoma, cataracts, macular oedema, posterior synechiae
• Long-term: vision loss, optic nerve damage, retinal detachment, neovascularisation

🎧MSRA Podcast:Argyll-Robertson Pupil – A Small Sign with Big Implications

In today’s DeepDive, we explore the Argyll-Robertson pupil– a classic and high-yield neurological sign that can unlock insight intoserious underlying conditions like neurosyphilis.

This is the “light-near dissociation” you absolutely needto know for the MSRA.

🧠What is theArgyll-Robertson Pupil?

• Bilateral, small, irregular pupils

• Do not react to light

• But constrict normally to accommodation (near focus)

• Classic for neurosyphilis, but also seen in otherneurological conditions

🧠Mnemonic: “ARP” =Accommodation Reflex Present, Pupillary Reflex Absent

🔍Key Causes to Know

• Tertiary syphilis (neurosyphilis) – most commoncause

• Diabeticneuropathy

• Midbrain lesions(e.g., Parinaud syndrome)

• Alcoholic midbraindegeneration

• Encephalitis

• Multiple sclerosis

• Pineal glandtumours

🔬Pathophysiology – WhyDoes This Happen?

• Damage to the pretectal area of the midbrain

• Disrupts light reflex pathway

• Accommodation reflex pathway is either sparedor takes an alternate route

• A brilliantclinical example of how localised neurologicaldamage can dissociate reflexes

🧪DifferentialDiagnoses

Don’t forget to ruleout:

• Adie’s (tonic) pupil

• Horner’s syndrome (with ptosis and anhidrosis)

• Opioid overdose (pinpoint pupils)

• Pharmacologic causes – e.g. miotic agents

📊Epidemiology

• Rare in the modern UK due to earlydiagnosis/treatment of syphilis

• Still important tospot in undiagnosed or inadequately treatedlate syphilis

• May be seen in global health contexts, or in patients with complex neurological presentations

🔎Clinical Features

• Bilateral, small, irregular pupils

• Poor or absentlight reflex

• Normalconstriction to near stimulus

• No direct visualcomplaint – diagnosis based on clinicalexamination

🧪Investigations

• Detailed eye exam including light and near reflex testing

• Syphilis serology: treponemal-specific andnon-specific tests

• Neuroimaging (MRI) if other midbrain pathologysuspected

• Consider CSF analysis if neurosyphilis is suspected

💉Management

• Treat the underlying cause, not the pupil abnormalityitself

• For neurosyphilis:

– IV high-dose penicillin G is the treatment ofchoice

– Monitor for Jarisch-Herxheimer reaction

• Addressco-existing neurological or infectious complications

📈Prognosis &Complications

• ARP itself causes no direct harm

• But underlyingneurosyphilis can lead to:

– General paresis

– Tabes dorsalis

– Cognitiveimpairment

– Vision and hearingloss

• Early detectionand treatment improve outcomes

🧠Quick Summary – Whatto Remember

• ARP = small, irregular pupils, poor light response,good near response

• Strongly associated with neurosyphilis

• Test with light and accommodation reflexes

• Confirm with syphilis serology

• Manage the underlying cause, not the pupil itself

• MSRA loves classicsigns – and this one is gold

👁️ Cataracts – High-Yield Revision for the MSRA 👁️

Welcome to anotherDeep Dive! Today we’re focusing on one of the most common causes of vision lossworldwide – cataracts.

🧠 What you'll learn in this episode:

• Clear definition of cataracts: progressive clouding of the lens leading to blurry vision
• Why age is the biggest culprit, but how trauma, diabetes, steroids, UV exposure & smoking also play key roles
• How cataracts present: think gradual vision loss, glare sensitivity, faded colours, halos, frequent glasses changes
• Types of cataracts (nuclear, cortical, subcapsular) and how they differ
• How to diagnose them (visual acuity, slit lamp exam, red reflex check, dilated fundoscopy)
• Definitive management: cataract surgery with IOL implantation
• Prognosis: excellent with surgery, but untreated cataracts can lead to blindness
• Key complications post-op: posterior capsule opacification (PCO), infection (endophthalmitis), or raised IOP

📝 Memory Aids:

• 🔑 Mnemonic: AFMSS for risk factors – Age, Family history, Medical conditions (esp. diabetes), Sunlight, Smoking
• 🔍 Symptoms: BGLCDH – Blurred vision, Glare, Low-light difficulty, Colour fading, Double vision, Halos

🎯 MSRA Focus:

• Know when surgery is indicated (not just vision score – based on functional impact)
• Surgery is the only curative treatment – drops & glasses help symptoms but don’t reverse the disease
• Posterior capsule opacification is the most common post-op issue and is fixed with YAG laser

🌍 Did you know?

• Over 12 million people globally are blind due to cataracts
• In the UK, >50% of people over 65 have cataracts, and 70% of those over 85
• Cataract surgery is one of the most commonly performed surgeries worldwide

🎧 Whether you're revising or just want to betterunderstand one of the most impactful eye conditions, this episode distilseverything you need to know into one clear, concise package.

🎧Deep Dive: AllergicConjunctivitis – MSRA Ophthalmology Essentials

You know that itchy,watery, red-eye feeling—especially during spring or when your pet curls up nextto you? That’s where today’s deep dive begins. We're unpacking allergic conjunctivitis — what it is, whatcauses it, and how to manage it effectively, especially for your MSRA prep.

👁️What Is It?

An inflammation of the conjunctiva triggered byallergens like pollen, pet dander, or dust mites. It's your immune systemoverreacting to harmless substances.

🧬Pathophysiology

Exposure toallergens → IgE binds to mast cells →release of histamine and inflammatory mediators→ itching, redness, watering, and swelling.

📌Key Risk Factors

• Personal or familyhistory of atopy (eczema, asthma,allergic rhinitis)

• Seasonal pollenexposure (hay fever overlap)

• Indoor allergens(dust mites, pets)

• Contact lens use(risk of Giant Papillary Conjunctivitis)

🧠Symptoms & Signs

• Intense itching – the hallmark symptom

• Bilateral red, watery eyes

• Puffy eyelids,chemosis (conjunctival swelling), papillae under lids

• History ofseasonal allergy or atopic conditions

❗DifferentialDiagnosis

Don’t confuse itwith:

• Infective conjunctivitis (viral/bacterial –sticky discharge)

• Uveitis, keratitis (pain, photophobia, visionloss)

• Blepharitis, scleritis, glaucoma – especiallyif pain, photophobia, or unilateral

🔍 Always ask: Is it itchy or painful? Pain = red flag 🚨

📊Epidemiology

• Affects up to 40% of the population

• Common in childrenand young adults

• Oftenunderdiagnosed

• Peaks in spring/summer (pollen), but can be perennial (dust/pets)

🩺Diagnosis

✅ Primarily clinical

✅ Based on history + bilateral itch/redness

🔬 Investigations (if needed):

• Conjunctival swab(to exclude infection)

• Allergy testing(if severe/recurrent)

• Slit lamp exam(for papillae, corneal involvement)

• Fluoresceinstaining (if keratitis suspected)

💊Management (UKNICE-Based)

1️⃣Avoidance – limit allergen exposure

2️⃣Cool compresses +artificial tears

3️⃣Topicalantihistamines – fast symptom relief

4️⃣Mast cell stabilisers – prevent recurrence

5️⃣Oral antihistamines – useful if hay fever present

6️⃣Steroid eye drops – only under ophthalmology care

🚫 Avoid rubbing eyes – it worsens inflammation!

📈When to Refer

🔺 Severe or persistent symptoms

🔺 Need for topical steroids

🔺 Unclear diagnosis

🔺 Suspected sight-threatening causes (uveitis,keratitis, etc.)

📅Prognosis

✅ Excellent in most common forms(seasonal/perennial)

⚠️Vernal and atopickeratoconjunctivitis carry risk ofcorneal damage – need specialist input

✅ Vision usually well preserved with proper care

🧠MSRA Key Takeaways

• Itch = Allergy

• Bilateral, red,watery eyes = classic

• Atopy is a strongclue

• Rule out painful, unilateral, or vision-threateningcauses

• Topicalantihistamines + stabilisers = 1st-line

• Refer if red flagsor steroid needed

🎓 Mnemonic: ITCH = Intense Tearing, Chemosis, Hyperaemia

🧰 Management: Avoid, Antihistamines, Artificial tears, Atropine(stabiliser)

📤 Referral if Pain, Photophobia, Poor vision

👁️‍🗨️ Age-related Macular Degeneration(AMD): The Fast Facts for MSRA 🚦

🔍 What is AMD?

• AMD = progressive degeneration of the macula (central retina) → central vision loss.
• #1 cause of severe visual impairment in older adults in the UK.

🧬 Types

• Dry (atrophic) AMD 🟡 (90%)
  Gradual loss, drusen (yellow deposits), slow atrophy.
• Wet (neovascular/exudative) AMD 💧 (10%)
  Rapid, severe vision loss. Caused by leaky, abnormal new blood vessels under the macula.

🧑‍⚕️ Causes & Risks

• Age ↑ (biggest risk)
• Genetics (family history)
• Smoking 🚬 (x2-5 risk & more severe)
• CV: Hypertension, high cholesterol, diabetes
• UV light ☀️, poor diet, obesity, Caucasian ethnicity, female gender

⚡️ Pathophysiology

• Dry: Drusen accumulate → damage retinal pigment epithelium (RPE) → photoreceptor loss.
• Wet: Choroidal neovascularization → vessels leak fluid/blood → fast central vision loss.

🤔 Differentials

• Diabetic maculopathy, myopic degeneration, CSR, macular dystrophies, macular hole, retinal vein/artery occlusion, late glaucoma, stroke/tumor (visual pathway), cataract, posterior vitreous detachment.

📊 Epidemiology

• Prevalence increases steeply with age:
  2.4% (>50y), 5% (>65y), 12% (>80y)
• 90% dry, 10% wet—but wet AMD causes most severe vision loss.

🛑 Symptoms

• Blurry or distorted central vision (trouble reading, faces)
• Metamorphopsia (straight lines bend)
• Central scotoma (dark/empty spot)
• Loss of contrast/colour, glare
• Charles Bonnet syndrome (visual hallucinations)

🩺 Diagnosis

• Fundoscopy: Drusen (dry); subretinal fluid, hemorrhage, exudates (wet)
• OCT (Optical Coherence Tomography): Essential for detecting retinal changes/fluid
• Fluorescein angiography: For diagnosis/planning wet AMD
• Amsler grid: Self-test for distortion

💊 Management

Dry AMD

• No cure—but slow progression:
• Lifestyle: Stop smoking, healthy diet (leafy greens, lutein)
• Supplements: AREDS2 (antioxidants, zinc, lutein, zeaxanthin)
• Low vision aids, regular monitoring

Wet AMD

• Urgent referral!
• Anti-VEGF injections (e.g., ranibizumab, aflibercept, bevacizumab)
• 🏥 Given monthly, then as needed based on OCT.
• Rare: Photodynamic therapy (PDT), laser (uncommon now)
• Supportive: Visual aids, driving advice, support groups

🧨 Complications

• Central vision loss → legal blindness
• Wet AMD: Rapid progression, subretinal hemorrhage, retinal detachment
• Anti-VEGF: Infection, inflammation, rarely retinal detachment, IOP rise
• Mental health: Depression, social isolation, falls risk

🎧MSRA Deep Dive: AcuteIritis (Anterior Uveitis)

Suddenpainful red eye? Blurred vision? Sensitivity to light? 🚨 Let’s break down one of the most tested ophthalmology topics for theMSRA: acute iritis, also known as anterior uveitis.

In this episode, wecover everything you need to know in a concise, high-yield format perfect forfast revision — or helping a patient in clinic. Get the essential facts,mnemonics, red flags, and NICE-aligned management steps all in one go.

🧠Core Learning Points

📌Definition

• Acute iritis = inflammation of the anterior uveal tract (iris + ciliary body)
• Most common type of uveitis
• Rapid onset (within hours–days)

📌Symptoms

🔺 Painful red eye

🔺 Photophobia (light sensitivity)

🔺 Blurred vision

🔺 Watery eye, no discharge

🔺 Usually unilateral

📝Mnemonic: PURR

Painful red eye

Unilateral

Reduced vision

Reaction to light

📌Differentials to RuleOut

• 🌫️ Conjunctivitis – itchy, gritty, sticky discharge
• 🌈 Acute angle closure glaucoma – severe pain, halos, vomiting, firm eye
• 🌊 Keratitis – corneal damage
• 🧠 Posterior/Intermediate/Pan-uveitis – different ocular zones

📌Causes

🔹 Idiopathic (most common)

🔹Autoimmune diseases:

• Ankylosing spondylitis
• Reactive arthritis
• Psoriatic arthritis
• IBD (Crohn’s/UC)
  🔹 Infections: HSV, TB, syphilis, HIV
  🔹 Trauma or post-op
  🔹 HLA-B27 associated (↑ risk)

📌Investigations

🧪Slit lamp exam – shows cells & protein flare in anteriorchamber

📏 Check intraocular pressure (to exclude secondaryglaucoma)

🧬 Bloods if: recurrent, bilateral, systemic symptoms

• HLA-B27
• ESR/CRP
• Autoimmune panel
  🩻 Chest X-ray – if sarcoidosis/TB suspected

📌Management

💧Topicalcorticosteroids (e.g. prednisolonedrops) – reduce inflammation

💧Cycloplegic drops (e.g. atropine) – dilate pupil, reduce pain &prevent synechiae

📉IOP-lowering drops – if raised pressure

📅 Taper steroids over 6+ weeks

🔁 Regular follow-up to prevent complications

📌Complications

🚨 Posterior synechiae (iris sticking to lens)

🚨 Secondary glaucoma

🚨 Cataracts (from inflammation/steroids)

🚨 Chronic uveitis or vision loss (if not treated)

📌Prognosis

👍 Excellent with prompt treatment

⚠️ Risk of recurrence (especially in HLA-B27+)

🎙️MSRA Podcast:Volvulus – A Critical Twist in the Gut

Today’s episodetackles one of the most dangerous causes ofacute abdominal pain: Volvulus.

From green vomit inneonates to sudden obstruction in elderly adults, we unravel the twisting pathology, clinical signs, andessential investigations you need to know for exams like the MSRA andreal-world clinical scenarios.

🔄What is Volvulus?

• A twist of the bowel around its mesentericattachment

• Leads to bowel obstruction and compromised blood flow

• Can affect the sigmoid colon, caecum, small intestine, or stomach

• When linked tocongenital issues, especially in children, it's often due to midgut malrotation

📦Causes & RiskFactors

• Congenital malrotation (especially in infants)

• Chronic constipation

• Adhesions from past abdominal surgery

• Neurological or motility disorders (e.g.,Parkinson’s)

• Connective tissue disorders

• Advanced age andanatomical variants (e.g., long mesentery)

🧠Mnemonic: “V forVolvulus = Vascular + Volumetric Twist”

🧠Pathophysiology

• Intestinal looptwists → mechanical blockage

• Simultaneouslycuts off blood supply → ischemia → necrosis →perforation

• Malrotation often underlies midgut volvulus,especially in neonates

• Surgical emergencydue to rapid onset of tissue death and sepsisrisk

📊Epidemiology

• Rare but serious

• Midgut malrotation occurs in ~1 in 500 to 1 in2,500 live births

• Most malrotation presents in infancy, but can remain silent into adulthood

• Volvulus is more common in older adults, particularly with predisposingfactors

🩺Clinical Features

• Sudden abdominal pain, vomiting, distension

• Inability to pass gas or stool

• In neonates: green (bilious) vomiting is a red flag

• In severe cases: shock, peritonitis,bloody stools, palpable abdominal mass

🧠Mnemonic: “V’s forVolvulus” – Vomiting, Very painful abdomen, no Voluntary bowel movements

🔍Differential Diagnosis

• General bowelobstruction

• Appendicitis

• Gastroenteritis

• IBS

• Intussusception

• Meckel’sdiverticulum

• Pancreatitis

• In females:ovarian torsion

• In neonates:Hirschsprung’s, NEC, pyloric stenosis

🧪Investigations

• Abdominal X-ray – Look for “coffee bean” sign (sigmoid)

• CT scan – Detailed visualisation of the twistand complications

• Upper GI contrast study – Especially useful formalrotation (bird’s beak sign)

• Ultrasound with Doppler – Can show “whirlpool sign” of twisted vessels

• Bloods: FBC,U&Es, lactate, CRP, infection markers

🧠Green vomiting =investigate immediately with contrast study or ultrasound

🛠️Management

• Definitive treatment = surgery

• Supportive care: fluids, antibiotics,electrolyte correction

• Proceduresinclude:

– Sigmoidoscopy for decompression (sigmoidvolvulus only)

– Right hemicolectomy for caecal volvulus

– Ladd’s procedure for volvulus due tomalrotation

• Laparoscopic options preferred when feasible

• In emergencies: resection of necrotic bowel may be required

⚠️Complications

• Bowel ischemia → necrosis,perforation, peritonitis, sepsis

• Short bowel syndrome – following resection

• Nutritional deficiencies, parenteral nutrition dependence

• Post-op adhesions, recurrence risk if nottreated definitively

🧠 Prevention in malrotation: elective Ladd’s procedure increasingly recommended even if asymptomatic

🎧MSRA Podcast:Superficial Thrombophlebitis – More Than Just a Red Leg

Welcome to thishigh-yield deep dive on SuperficialThrombophlebitis — a deceptively common condition with importantclinical implications. Whether you're revising for the MSRA or improving your diagnostic thinking, this episode breaksdown what you need to know: definition, riskfactors, differentials, diagnosis, and management — all grounded in UKclinical guidelines.

🧠What You’ll Learn inThis Episode:

✅Definition

• Inflammation +thrombus formation in a superficial vein (most commonly the long saphenous vein)

• Typically in the legs, but may occur elsewhere (breast, penis)

• Usually non-infective, but septic cases exist

⚠️Risk Factors &Causes

• Varicose veins

• IV cannulation, trauma, or direct injury

• Prolonged immobility, pregnancy

• Hypercoagulable states – thrombophilia,malignancy

• Smoking, obesity, recent surgery

🧠 Mnemonic: VIP-TVPB – VeinInjury, Immobility, Pregnancy, Trauma, Varicose veins, Pro-coagulable Blood

🧬Pathophysiology

• Clot forms in asuperficial vein → local inflammation

• Can cause pain, redness, swelling, and a palpable cord-like vein

• Risk of extension into deep veins (DVT) → pulmonaryembolism

🔍DifferentialDiagnosis

• Deep Vein Thrombosis (DVT) – always rule out

• Cellulitis

• Lymphangitis

• Baker’s cyst

• Migratory thrombophlebitis (Trousseau’s sign) –consider malignancy

• Vasculitis-related phlebitis

🧠 Tip: Red, swollen leg ≠ always DVT. Think broadly.

📊Epidemiology

• Occurs in 3–11% of the population

• More frequent in warmer months

• Affects all ages, slightly more common in women

• Often seen inpatients with varicose veins or IV lines

🩺Clinical Features

• Localised pain, redness, warmth, swelling

• Palpable cord along the vein

• Skin may appear discoloured or feel firm

• Often self-limiting, but needs careful assessment

🧠 Variant: Mondor’s disease(in the breast)

🧪Investigations

• Clinical exam + good history = essential

• Duplex ultrasound: confirms clot, rules out DVT

• Blood tests forthrombophilia in recurrent/unexplained cases

• DO NOT use venography (can worsen condition)

• If infection suspected (e.g. via IV cannula):remove device + culture tip

💉Management

• Conservative First Line

 – Warm compresses

 – Limb elevation

 – Simple analgesia(e.g. paracetamol)

 – Oral/topical NSAIDs

 – Compression stockings (check ABPI first)

• Encourage gentle mobilisation

• Anticoagulation (LMWH or fondaparinux):

 – Consider if clotis near sapheno-femoral junction

 – Or for extensive thrombophlebitis to prevent DVT

• Antibiotics: only if signs of infection orsepsis

• Surgical vein removal: for severe or recurrentvaricose-related cases

📉Complications

• DVT (20% risk in some cases)

• Pulmonary embolism (PE) – rare but serious

• Recurrence

• Infection – suppurative phlebitis

• Chronic venous insufficiency

• Skin hyperpigmentation, residual lumps

🧠 MSRA Tip: Proximal clots near deep vein junctions= higher risk → consider anticoagulation

📈Prognosis

• Generally excellent with appropriate management

• Most cases resolvewithin a few weeks

• Risk of recurrenceand complications increases with underlyingvenous disease or past DVT/PE

🎧Deep Dive: SmallBowel Obstruction – MSRA Surgery Essentials

You know that stuckfeeling in the gut? That’s our jumping-off point for today’s topic: small bowel obstruction – a surgical emergencyyou absolutely need to know inside out for the MSRA.

🔎What Is It?

A blockage in the small intestine that stopsfood, fluid, and gas from moving normally.

Two types:

• Mechanical – physical blockage (adhesions,hernias, tumours)

• Functional – bowel motility failure (e.g.paralytic ileus)

⚠️Causes & RiskFactors

✅ Adhesions (from prior surgery – most common)

✅ Hernias (can strangulate)

✅ Tumours

✅ Crohn’s disease (strictures)

✅ Volvulus, intussusception, gallstone ileus

✅ Post-op ileus, opioid use

✅ Bowel malrotation in children

🧠Pathophysiology

• Blockage → fluid +gas build up

• Bowel stretches →pressure rises

• Blood flow iscompromised → ischaemia, necrosis, perforation

Mnemonic: Blockage → Buildup → Bowel distension → Blood flowcompromise → Bad outcome

🧬Differentials

🌀 Large bowel obstruction

🦠 Gastroenteritis

🔥 Pancreatitis, appendicitis

🩺 Mesenteric ischaemia

🧪 Perforated ulcer or tumour

🧒 In kids: Intussusception, malrotation

👩 Women: Ovarian torsion, ectopic

📊Epidemiology

• Very common inemergency surgery

• Most frequent inolder adults

• Recurrence risk ishigh after previous SBO

🩺Clinical Features

• Crampy abdominal pain (colicky → constant ifischaemia)

• Distension and bloating

• Vomiting (early: bile, late: feculent)

• Absolute constipation – no flatus/stool

• Hyperactive bowel sounds early → absent late

🩻Diagnosis

1. Examination – scars, distension, hernias, sounds
2. X-ray – dilated loops + air-fluid levels
3. CT with contrast – gold standard for location, cause, complications
4. Bloods – FBC, U&Es, lactate, group & save
5. Fluids – monitor urine output, correct dehydration

💉Management Overview

🔹Drip & suck (NBM, IV fluids, NG tube)

🔹Conservative (if partial, no red flags)

🔹Surgical (if complete, strangulated, or fails to resolve)

🔹Stenting – for malignancy

🔹Volvulus – endoscopic decompression (sigmoid), surgery ifneeded

🔹Pseudo-obstruction – neostigmine, decompression

🧬Complications

❌ Bowel ischaemia → necrosis → perforation → sepsis

❌ Shock, AKI, malnutrition

❌ Short bowel syndrome (if large resection)

❌ High recurrence risk (especially adhesions)

✅MSRA Key Takeaways

✔️ Think adhesions, hernias, tumours

✔️ SBO = emergency → CT critical

✔️ Key symptoms: pain, distension, vomiting, no stool

✔️ Early treatment = better outcomes

✔️ Red flag signs = prompt surgery

🏥 Testicular Torsion: UROLOGICAL EMERGENCY 🚨

🚦 The Essentials

• Testicular torsion = twisting of the spermatic cord → blood supply cut off!
• Think: “Twisting cord, blood flow ignored.”
• 💡 Most common in males 10–30 yrs (peak: 13–16), but can happen at any age (including neonates).

🧬 Why Does It Happen?

• Bell clapper deformity (testicle free to twist)
• 🧬 Family history/genetic factors
• 💥 Sudden movement, trauma, or sometimes no obvious trigger

🚩 Classic RED FLAGS

• ⚡️ Sudden, severe, one-sided testicular pain (may wake from sleep)
• 💥 Scrotal swelling & redness
• 🤢 Nausea & vomiting
• ❌ Absent cremasteric reflex (no upward movement when inner thigh stroked)
• 🔝 High-riding, horizontal testis
• History of previous similar pain? (suggests intermittent torsion!)

🩺 Key Differentials

• Epididymo-orchitis (usually older, slower onset, urinary/STI signs)
• Torsion of appendix testis (blue dot sign)
• Trauma, hernia, tumour (usually painless, gradual), hydrocele
• Mnemonic: Severe pain, swollen & red, reflex fled

📈 Epidemiology

• Incidence: ~1 in 4,000 males <25
• Peak: Adolescence
• Time = Testicle: 6hr = 90–100% salvage; >12hr = 50% or less!

🩻 Investigations

• Clinical diagnosis is KING 👑 – don’t delay!
• 🔊 Doppler ultrasound: Absence of blood flow (can help but don’t delay surgery if high suspicion)
• 🧪 Urinalysis: Rule out infection

UK/US guidelines:

If clinicalsuspicion is high, immediate surgicalexploration—do NOT wait for scan.

🔪 Management

• EMERGENCY SURGERY: Detorsion + orchidopexy (fix both sides)
• Attempt manual detorsion only if immediate surgery not available (temporary)
• Orchidectomy if testis is non-viable
• Prosthesis option later if needed
• Mnemonic: “Six-hour window, high-win ratio”

😱 Complications

• Testicular loss/atrophy (irreversible tissue death)
• Infertility/subfertility (can affect both testes via immune response)
• Recurrence if not fixed
• Psychological distress
• Infection/abscess if tissue necrosis

🔑 TAKEAWAY

• Sudden testicular pain = torsion until proven otherwise!
• ACT FAST: Every minute counts for testicular survival & fertility!
• 🚑 If in doubt, get help—no delay!
