💥 FREE MSRA PODCAST – Herpes Simplex Virus (HSV): The Essentials, Exam Tricks & Real-World Insights 💡
Your shortcut to mastering herpes simplex virus for the MSRA: fast, focused, and packed with everything you need to remember.

🧠 Key Learning Points

📌 Definition• Herpes simplex virus (HSV) is a highly contagious DNA virus—two main types: HSV-1 (oral, “cold sores”) and HSV-2 (genital, “herpes”), but both can affect either site.• Causes painful blisters/ulcers on skin or mucous membranes, with a tendency for lifelong, recurrent episodes.

📌 Causes & Transmission• HSV-1: Primarily oral-to-oral (kissing, shared items), but can cause genital infection (often oral sex).• HSV-2: Mainly sexually transmitted—genital to genital.• Key Fact: Virus spreads via direct contact—skin, saliva, genital secretions, and crucially, asymptomatic viral shedding (can transmit even without symptoms).

📌 Risk Factors• Unprotected sex• Multiple partners• Immunosuppression (HIV, steroids, chemo)• Previous HSV infection (type 1 ≠ type 2 immunity)• Direct contact with active lesions

📌 Pathophysiology• Virus enters through tiny skin/mucosal breaks → infects local cells → creates painful blisters/sores• Latency: HSV hides in sensory nerve ganglia (trigeminal for oral, sacral for genital), reactivates with triggers (stress, fever, sunlight, menstruation) causing recurrent outbreaks.

📌 Differential Diagnosis• Oral: Varicella zoster (shingles), coxsackie (hand, foot, mouth), aphthous ulcers• Genital: Syphilis, chancroid, aphthous ulcers, lichen planus, other viral/bacterial causes

📌 Epidemiology (UK Focus)• Common: Most adults carry HSV-1; HSV-2 less prevalent but increasingly diagnosed• Genital herpes: Traditionally HSV-2, but HSV-1 is rising as a cause (especially in young people and via oral sex)

📌 Clinical Features• Primary outbreak: Painful blisters/ulcers, can be extensive; fever, malaise, headache, tender nodes• Recurrent outbreaks: Shorter, milder, prodrome (tingling/itching); oral: cold sores, genital: local blisters/ulcers• Special: Gingivostomatitis in children (widespread oral ulcers, pain, dehydration risk)

📌 Diagnosis• Clinical appearance + history is often enough• Lab confirmation: – PCR from swab (gold standard—most sensitive, fast) – Viral culture (less sensitive, slower) – Serology (antibodies)—useful for past infection, not acute diagnosis

📌 Management (UK NICE/CKS-aligned)• Antivirals: Aciclovir, valaciclovir, famciclovir – Episodic: Short course at onset of symptoms – Suppressive: Long-term for frequent/severe recurrences (reduces outbreaks & transmission risk)• Supportive care: Analgesia, saline bathing, barrier creams, keeping area clean/dry• Patient education: Asymptomatic transmission, safe sex (condoms reduce but don’t eliminate risk)• Special cases: – Severe oral (gingivostomatitis): Oral aciclovir + chlorhexidine – Pregnancy: Primary HSV in late pregnancy → C-section + antivirals to prevent neonatal herpes

📌 Complications
• Neonatal herpes (rare but severe—especially with primary maternal infection late in pregnancy)
• Severe/disseminated infection in immunocompromised
• Herpes encephalitis, keratitis (eye), meningitis
• Psychological impact, recurrent discomfort

📌 Prognosis
• Lifelong infection—virus remains latent in nerves
• Major complications rare

💥 FREE MSRA PODCAST – Genital Herpes: High-Yield, Stigma-Free Exam Essentials 💡
Master everything you need to know about genital herpes—from causes and diagnosis to key memory tricks, management, and real-life clinical tips. Designed for fast revision, GP training, and MSRA success!

🧠 Key Learning Points

📌 Definition
• Genital herpes is an STI caused by herpes simplex virus (HSV-1 or HSV-2).
• Classic feature: Recurrent, often painful blisters or sores around the genitals or anus.

📌 Causes & Transmission
• Usually HSV-2 (traditionally genital), but HSV-1 (the “cold sore” virus) now common due to oral sex.
• Direct contact with infected skin/mucous membranes—vaginal, anal, or oral sex.
• Key Point: Up to 80% of cases spread by people with no symptoms (asymptomatic shedding).

📌 Risk Factors
• Unprotected sex, multiple partners, history of other STIs
• Younger age at first sex
• MSM (men who have sex with men), female sex (anatomical risk)
• Immunosuppression (HIV, steroids, chemo)

📌 Pathophysiology
• Virus enters through tiny skin breaks, travels along sensory nerves, becomes dormant (latent) in nerve ganglia.
• Stress, illness, menstruation, etc. can trigger reactivation—virus travels back down nerves causing new sores.

📌 Differential Diagnosis (Mnemonic: Very Often Similar Skin Stuff Requires Better Guessing How)
• Vulvovaginal candidiasis (thrush), other STIs (gonorrhoea, syphilis), skin disorders (psoriasis, eczema), lichen sclerosus, reactive arthritis, genital malignancy (rare), herpes zoster (shingles)

📌 Epidemiology
• Extremely common: 30,000+ new UK cases per year (most in ages 15–24)
• HSV-1 now responsible for many genital cases in the UK

📌 Clinical Features
• Primary infection: Painful blisters/ulcers, itching/tingling (prodrome), swollen groin nodes, flu-like symptoms (fever, malaise), dysuria, can last up to 4 weeks
• Recurrences: Shorter, milder, often just on one side (unilateral), usually no systemic symptoms
• Asymptomatic cases common

📌 Diagnosis
• Clinical exam—typical sores, lymphadenopathy
• NAAT/PCR swab from lesion—gold standard
• Serology (antibody test): Not first-line, but useful for atypical/recurrent cases or partner screening

📌 Management
• Antivirals: Aciclovir, valaciclovir, famciclovir (shorten and reduce severity, but do not cure)
• Episodic therapy: Take at start of outbreak
• Suppressive therapy: Daily low-dose antivirals for frequent/severe recurrences (reassess after 12 months)
• Supportive: Pain relief, saline bathing, lidocaine gel, barrier creams, practical advice
• Counselling: Vital! Address stigma, signpost to Herpes Viruses Association ( https://herpes.org.uk ), support for disclosure, safer sex, pregnancy risk

📌 Prognosis & Prevention
• No cure—lifelong latent infection, but outbreaks usually decrease over time
• Condoms lower risk (but not 100% protective)
• Suppressive antivirals reduce asymptomatic shedding
• No effective vaccine (yet)
• Most live well with proper management and support

📌 Complications
• Frequent recurrences, psychological impact, stigma
• Higher risk of HIV/STI transmission
• Neonatal herpes (if passed on during birth—rare but serious)
• Severe/prolonged disease in immunocompromised
• Rare: aseptic meningitis, autonomic neuropathy, urinary retention, superinfection

• HPV types 6 & 11
• Unprotected sex
• Multiple partners
• Early sexual activity
• Smoking
• Anoreceptive intercourse
• Immunosuppression (e.g., HIV)
🧠 Mnemonic: “Sex Starts Making HPV Spread Incredibly”

📌 Pathophysiology
• HPV infects epithelial cells → viral replication → benign wart formation
• Virus may remain latent → recurrence possible
• Warts = hyperplasia, not cancer (but check for co-infection with high-risk HPV)

📌 Symptoms

📌 Diagnosis
• Clinical diagnosis – visual inspection
• Acetic acid test (turns lesions white – not specific)
• Biopsy if atypical or suspicious for malignancy
• STI screening essential

📌 Management
• Topical: Podophyllotoxin, Imiquimod
• Physical: Cryotherapy, excision, laser
• Avoid Podophyllotoxin/Imiquimod in pregnancy
• HPV vaccine (covers 6, 11, 16, 18) for prevention
• Reassure re: benign nature
• STI screen and treat if positive
• Partner treatment not always necessary

📌 Complications
• Recurrence (common due to viral latency)
• Emotional distress and stigma
• Pain during sex
• Slightly increased STI risk
• In children: consider safeguarding concerns

📌 Prognosis

🦠 FREE MSRA PODCAST – Chancroid: Painful Genital Ulcers, Rapid Diagnosis & Management 🚦

A must-know for exams and clinical practice! This high-yield episode distils everything you need about chancroid—from classic painful ulcers to diagnosis, treatment, and public health tips. Get the essentials fast for your MSRA revision.

🧠 Key Learning Points

📌 Definition
• Chancroid is a sexually transmitted infection (STI) caused by Haemophilus ducreyi
• Characterised by painful genital ulcers (the classic sign!) and swollen groin lymph nodes (buboes)

📌 Causes & Transmission
• Spread via sexual contact (vaginal, anal, oral)
• Bacteria enter through tiny skin/mucosal breaks during sex
• Risk factors: unprotected sex, multiple partners, history of STIs, sex work, travel to endemic regions

📌 Mnemonic: D.U. Cray = D.U.lcerous sores
(Haemophilus ducreyi → painful D.U.lcers)

📌 Pathophysiology
• Bacteria invade at microabrasions, cause local tissue destruction → ulcers
• Body responds with inflammation; pus in ulcers is infectious
• Ulcers increase risk of HIV transmission!

📌 Clinical Features
• Painful soft genital ulcers with ragged/undermined edges
• Swollen, tender inguinal lymph nodes (buboes)
• Ulcer base may appear necrotic, covered in grey/yellow exudate
• May merge into larger ulcers, sometimes with fever/malaise

📌 Differential Diagnosis
• Syphilis (typically painless ulcer)
• Genital herpes (painful blisters/ulcers)
• Lymphogranuloma venereum (LGV)
• PCR testing from ulcer is essential for confirmation
• Test for other STIs (syphilis, HIV, herpes) as coinfection is common

📌 Epidemiology
• Rare in the UK—more common in Africa, Asia, Latin America, Caribbean
• Associated with limited sexual health resources

📌 Investigations
• Clinical assessment + PCR from ulcer swab (most reliable)
• Culture possible but technically challenging
• Always screen for other STIs!

📌 Management
• Antibiotics:
 – Single-dose azithromycin (oral)
 – Single-dose ceftriaxone (IM injection)
 – Alternatives: erythromycin or ciprofloxacin
• Supportive care: pain relief, saline compresses
• Incision/drainage for fluctuant lymph nodes (buboes) if needed
• Public health: Contact tracing & partner treatment—vital to stop reinfection

📌 Complications
• Abscess formation (from untreated buboes)
• Secondary infection, scarring/disfigurement
• Greatly increased HIV transmission risk if untreated

📌 Prognosis
• Excellent with prompt antibiotics—ulcers usually heal without much scarring
• Delayed treatment → abscess, scarring, public health risk

🦠 FREE MSRA PODCAST – Candidiasis: Thrush, Invasive Fungal Disease & Exam Essentials 🌟

This high-yield deep dive breaks down candidiasis (thrush)—from everyday oral or vaginal infections to serious, life-threatening invasive disease. Ideal for your MSRA revision or clinical practice. Packed with exam-focused tips, memorable mnemonics, and practical advice!

🧠 Key Learning Points

📌 Definition
• Candidiasis (thrush) = fungal infection caused by Candida species
• Candida albicans is the most common culprit, but others matter too (glabrata, tropicalis, auris, etc.)
• May be local (mouth, vagina, skin) or systemic (bloodstream, organs)

📌 Causes & Risk Factors
• Overgrowth often triggered by:
 – Antibiotics (wipe out normal flora)
 – Immunosuppression (HIV, cancer, steroids, transplant)
 – Diabetes (esp. poorly controlled)
 – Hormonal changes (pregnancy, oral contraceptives)
 – Moisture, poor hygiene, obesity
 – Medical devices (catheters, central lines)
• Non-albicans species and drug-resistant strains (Candida auris) are rising globally

📌 Mnemonic: I DO A POOR HAT
Immunosuppression
Diabetes
Oral contraceptives
Antibiotics
Pregnancy
Obesity
Oral/poor hygiene
Renal replacement
Hospitalisation/ICU
Age extremes
Tight clothing

📌 Pathophysiology
• Overgrowth → yeast cells form hyphae & biofilms → invade tissue → inflammation (redness, soreness, discharge)
• Systemic disease occurs when candida enters the bloodstream in vulnerable patients

📌 Clinical Features
• Oral (thrush): White “cottage cheese” patches (can be wiped off, leaving red base), soreness
 – 6 types: Pseudomembranous, acute/chronic erythematous, chronic plaque, median rhomboid glossitis, angular cheilitis
• Genital (vulvovaginal): Intense itch, thick white discharge, soreness
• Skin: Red, moist, macerated rash in folds
• Systemic: Fever, chills, organ-specific symptoms if invasive

📌 Diagnosis
• Usually clinical for mild/local cases
• Swabs or scrapings + microscopy/culture for confirmation, especially if recurrent/atypical
• Blood cultures for suspected systemic infection
• Imaging if deep organ involvement suspected

📌 Management
• Local/mild: Topical azoles (clotrimazole, miconazole), nystatin suspension (oral), oral fluconazole for severe/recurrent cases
• Systemic: IV echinocandins (caspofungin/micafungin), IV/PO fluconazole, amphotericin B
• Address underlying risk factors: Glycaemic control, hygiene, medication review
• Prevention: Hygiene, drying skin folds, rinse mouth after inhaled steroids

📌 Complications
• Recurrent/chronic infection
• Invasive candidiasis (candidaemia, organ dysfunction, potentially fatal if untreated)
• Antifungal resistance (esp. Candida auris, glabrata, krusei)

📌 Prognosis
• Localised: Excellent with prompt treatment
• Systemic: High mortality in immunocompromised—urgent treatment essential

📌 Causes & Risk Factors
• Spread via vaginal, anal, or oral sex
• Risk factors:

• Unprotected sex 🚫

• Multiple sexual partners

• Previous STIs

• Immunosuppression

• More commonly diagnosed in women
  💡 Mnemonic: “Many STIs Multiply TRICH Risks” – Multiple partners, STI history, TRICH contact

📌 Pathophysiology
• T. vaginalis attaches to urogenital epithelium → causes local inflammation
• Moves via flagella; triggers immune response
• Can persist without treatment and cause ongoing damage

📌 Symptoms
• Women:

• Itching, burning, dysuria

• Frothy yellow-green discharge, strawberry cervix 🍓

• pH > 4.5
  • Men: Often asymptomatic; may have mild urethritis or discharge
  💡 Mnemonic: “TRICH Froths Then Burns”

📌 Differential Diagnosis
• Women: BV, candidiasis, chlamydia, gonorrhoea, herpes, forgotten tampon
• Men: Urethritis, prostatitis, cystitis

📌 Diagnosis
• NAAT (PCR): gold standard 🧪
• Wet mount: visualise motile trophozoites
• Test sexual partners & screen for co-STIs
💡 Tip: Must test quickly if using wet prep – mobility drops within 10 mins

📌 Management
• Metronidazole:

• 2g single dose OR

• 400–500mg BID for 5–7 days
  • Treat ALL sexual partners regardless of symptoms
  • Abstain from sex until both partners are treated
  • In pregnancy: use metronidazole (long course preferred)
  ⚠️ Resistance exists – monitor if symptoms persist

⚕️ FREE MSRA PODCAST – Bacterial Vaginosis
🎧 A clear, high-yield breakdown of this common vaginal discharge disorder – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Bacterial vaginosis (BV) is a non-STI condition caused by an imbalance in vaginal flora – specifically a reduction in lactobacilli and overgrowth of anaerobes like Gardnerella vaginalis.

📌 Causes & Risk Factors
• Overgrowth of anaerobic bacteria (e.g. Gardnerella, Prevotella, Mobiluncus)
• Reduced lactobacilli → ↑ pH
• Sexual activity (new partners)
• Use of copper IUD
• Vaginal douching, bubble baths
• Receptive oral sex
• Smoking
• Higher prevalence in Afro-Caribbean women
💡Mnemonic: "SEX COORS" – Sexual activity, Ethnicity, X-linked hygiene (douching), Copper IUD, Oral sex, Recurrent partners, Smoking

📌 Pathophysiology
• ↓ Lactobacilli → ↑ vaginal pH (>4.5)
• Less H₂O₂ → anaerobes thrive
• Anaerobes release amines (putrescine, cadaverine) → fishy odor
💡Think: "Garden gone wild" – Lactobacilli are gardeners, anaerobes are weeds

📌 Symptoms
• Thin, grey-white, homogeneous vaginal discharge
• Fishy odour (esp. after sex or menstruation)
• Mild irritation or burning (less common)
• Often asymptomatic (≈50%)
💡Mnemonic: “Gray, Fishy, Maybe Itchy, Maybe Nothing”

📌 Differential Diagnosis
• Candidiasis (thick, white discharge)
• Trichomoniasis
• Chlamydia, Gonorrhoea
• Herpes simplex
• Atrophic vaginitis (postmenopausal)
• Irritant vaginitis (e.g. soaps, foreign body)
• Normal physiological discharge

📌 Diagnosis
• Clinical assessment + pelvic exam
• Vaginal pH >4.5
• Amsel's Criteria (need 3/4):

• Homogeneous grey-white discharge

• Clue cells on microscopy

• Vaginal pH >4.5

• Positive whiff test (fishy odor on KOH)
  💡Quick tip: Discharge, Clue, pH, Whiff = Amsel

📌 Management
• First-line: Oral metronidazole 400–500mg BD for 5–7 days
• Alternatives: Intravaginal metronidazole gel or clindamycin cream
• Avoid vaginal douching
• No need to treat asymptomatic cases unless pregnant or undergoing termination
• Recurrent BV: consider metronidazole gel 2x/week or Astodrimer gel
• Probiotics – evidence limited
💡Mnemonic: “Metro or Clinda to Clear, Avoid Douching to Dodge”
📌 NICE CKS: https://cks.nice.org.uk/topics/bacterial-vaginosis/

📌 Complications
• ↑ Risk of HIV & STIs
• Pregnancy risks: preterm birth, low birth weight, PPROM
• Postpartum endometritis
• High recurrence (up to 70% within 3 months)

📌 Prognosis
• Usually benign and self-limiting
• Recurrence is common – prevention and patient education are key

⚕️ FREE MSRA PODCAST – Wilms’ Tumour
🎧 A clear, high-yield breakdown of this common childhood kidney cancer – perfect for exam prep and real-life clinical scenarios.

🧠 Key Learning Points

📌 Definition
• Wilms’ tumour (also called nephroblastoma) is a renal cancer primarily affecting children under 5.
• Typically arises from fetal kidney precursor cells that fail to differentiate properly.

📌 Causes & Risk Factors
• Genetic mutations (especially WT1, WT2)
• Syndromic associations:
• WAGR syndrome (Wilms, Aniridia, Genitourinary anomalies, Retardation)
• Beckwith-Wiedemann syndrome
• Denys-Drash syndrome
• Other associated syndromes: Perlman, Sotos, Simpson-Golabi-Behmel
• Family history (rare, ~1–2%)
• Congenital anomalies even without named syndrome
💡 Mnemonic: “WAG the Beckwith” for key syndromes

📌 Pathophysiology
• Mutations disrupt normal development of nephron precursor cells
• Results in proliferation without differentiation, forming a solid renal tumour
• WT1 gene (on chromosome 11) is most commonly implicated

📌 Symptoms
• Painless abdominal mass (most common)
• Hematuria (painless)
• Hypertension
• Abdominal pain
• Systemic symptoms: fever, weight loss, fatigue
• Rare: UTI, respiratory symptoms if lung metastases present
💡 Mnemonic: “PMHH” – Painless Mass, Hematuria, Hypertension

📌 Differential Diagnosis
• Mesoblastic nephroma (infants)
• Clear cell sarcoma of kidney
• Renal cell carcinoma (rare in children)

📌 Diagnosis
• Ultrasound (initial test)
• CT/MRI – for staging, tumour extent, vascular invasion, and metastases
• Histology via surgical biopsy – needle biopsies often avoided
• Bloods: FBC, U&Es, urinalysis
• Consider screening in high-risk syndromes (every 3–4 months up to age 5–7)

📌 Management
• Multidisciplinary team approach
• Nephrectomy – surgical removal of tumour and affected kidney
• Chemotherapy – often given pre-op (neoadjuvant) and post-op
• Drugs: vincristine, dactinomycin, doxorubicin; ± cyclophosphamide
• Radiotherapy – for stage III disease or unfavourable histology
✅ NICE-aligned: Urgent referral within 48h for any unexplained abdominal mass

📌 Complications
• Metastasis (commonly lungs, ~20% at diagnosis)
• Tumour rupture and haemorrhage
• Chemotherapy complications – neutropenia, infection, nausea
• Radiation toxicity
• Long-term risk of second cancers (e.g. sarcoma, leukaemia, breast cancer)
• Impaired renal function (post-nephrectomy)

📌 Prognosis
• Excellent with early treatment – ~90% overall survival in the UK
• Factors affecting prognosis:
• Stage at diagnosis
• Tumour histology (favourable vs unfavourable)
• Response to chemotherapy
• Age and bilateral involvement
