Infections of the Foreskin (Prepuce/Posthitis) and Glans (Balanitis/Balanoposthitis): Viral vs. Fungal vs. Bacterial

1. FUNGAL Infections (Most Common)

Causative Organisms

• Candida albicans - by far the most common single pathogen
• Other Candida spp. less frequently

Risk Factors

• Diabetes mellitus (recurrent candidal balanitis should prompt blood glucose testing)
• Poor hygiene, tight foreskin (phimosis)
• Antibiotic use (disrupts normal flora)
• Immunosuppression (HIV, steroids)
• Sexual contact with partner who has vaginal candidiasis

Clinical Features

• Erythema of the glans and inner prepuce - often vivid red
• Satellite lesions: small pustules or papules around the main erythematous patch (characteristic of Candida)
• Thick, curdy (cottage-cheese-like) white discharge under the foreskin
• Soreness and itch - often more itch than pain
• Skin may appear glazed or shiny
• Unpleasant cheesy odour from smegma accumulation

Diagnosis

• KOH (potassium hydroxide) preparation of swab - shows pseudohyphae and yeast buds
• Swab culture on Sabouraud's agar

Treatment

• First-line: Topical clotrimazole or miconazole cream to glans and prepuce
• Oral: Fluconazole 150 mg single dose for moderate-severe cases; 2-3 doses 72 hours apart for severe/recurrent cases
• Hygiene measures (gentle retraction, washing, drying)
• Recurrent cases: investigate for diabetes

2. BACTERIAL Infections (Second Most Common)

Causative Organisms

• Streptococcus spp. (beta-haemolytic strep most common aerobic cause)
• Staphylococcus aureus
• Pseudomonas spp.
• Neisseria gonorrhoeae (STI-associated)
• Chlamydia trachomatis (STI-associated)
• Gardnerella vaginalis
• Mycoplasma genitalium

• Bacteroides spp.
• Other mixed anaerobes

• Treponema pallidum (syphilis) - presents as a painless chancre

Clinical Features - General Bacterial

• Warmth, erythema, and oedema of glans, foreskin, and sometimes penile shaft
• Purulent, malodorous discharge on foreskin retraction
• Excoriation and tenderness
• Foul smell specifically suggests anaerobic infection
• Discharge, lymphadenopathy, or urethral discharge raises suspicion for STI

Specific Bacterial Presentations

Diagnosis

• Swab for culture and sensitivity (aerobic + anaerobic)
• STI screen (gonorrhoea, chlamydia, syphilis serology, RPR) if STI suspected
• Urinalysis if dysuria present

Treatment

• Mixed flora / mild: Topical bacitracin + hygiene measures
• Anaerobic infection: Oral metronidazole 500 mg twice daily x 7 days, or clindamycin 300 mg three times daily x 7 days
• Aerobic/streptococcal: Cephalexin (especially in children, 25-50 mg/kg/day divided doses x 7 days)
• Gonorrhoea: Ceftriaxone IM 500 mg + azithromycin
• Syphilitic chancre: Benzathine penicillin G IM
• Severe cellulitis: IV antibiotics and urological consultation

3. VIRAL Infections (Least Common among infectious causes)

Causative Organisms

• Herpes Simplex Virus (HSV-2, less often HSV-1) - most common viral cause
• Human Papillomavirus (HPV) - causes condylomata acuminata (genital warts)
• Molluscum contagiosum

HSV (Genital Herpes)

• Pathognomonic feature: Grouped erythematous vesicles on a red base, on the glans and prepuce
• Vesicles rapidly rupture to form shallow, painful ulcers with erythematous edges
• Pain is prominent - burning/stinging (unlike syphilitic chancre)
• May have prodrome: local tingling, burning before vesicle eruption
• Tender inguinal lymphadenopathy
• Dysuria if urethral involvement
• Recurrent episodes less severe than primary infection (virus remains latent in dorsal root ganglia)
• Systemic symptoms (fever, malaise) more pronounced in primary infection

HPV (Condylomata Acuminata / Genital Warts)

• Soft, flesh-coloured, cauliflower-like papules on the prepuce, coronal sulcus, and glans
• Usually painless unless secondarily infected
• May coalesce into large warty masses
• Diagnosis: clinical (aceto-white test with 5% acetic acid)
• Treatment: Podophyllin, imiquimod cream, cryotherapy, or surgical excision

Molluscum Contagiosum

• Caused by a poxvirus
• Pearly, dome-shaped papules with central umbilication on penile skin and prepuce
• Usually asymptomatic, multiple lesions
• Treatment: cryotherapy, curettage

Quick Comparison Table

Key Clinical Pearls

1. Recurrent Candida balanitis in an adult should always prompt fasting blood glucose to rule out diabetes mellitus.
2. Foul smell = anaerobe - think Bacteroides, treat with metronidazole.
3. Grouped vesicles = HSV until proven otherwise; never squeeze or incise them.
4. A painless indurated ulcer on the prepuce = syphilis (chancre) until serology proves otherwise.
5. Infections frequently show mixed flora (fungal + bacterial co-infection); broad-spectrum coverage with topical antifungal + antibiotic may be needed empirically.
6. Balanoposthitis can be the sole presenting sign of diabetes - always consider in adult males presenting with recurrent cases.
7. Persistent or treatment-refractory balanitis warrants biopsy to exclude premalignant (Erythroplasia of Queyrat) or malignant conditions.

• Orange - Fungal (Candida): itchy, curdy white discharge, satellite pustules, linked to diabetes
• Red - Bacterial (Mixed Flora): purulent/foul discharge, warmth and swelling, includes STI pathogens like gonorrhoea and syphilis
• Blue - Viral (HSV/HPV): grouped vesicles turning to painful ulcers (HSV), cauliflower warts (HPV), with a burning prodrome

Vatakantaka (वातकण्टक)

Etymology & Concept

Modern Correlation

Anatomy (Modern Understanding)

• Originates at the medial calcaneal tuberosity (heel bone)
• Fans out across the sole of the foot
• Inserts into the proximal phalanges (toes)

Ayurvedic Pathology (Samprapti)

Symptoms

Classic Presentation (both Ayurvedic & Modern)

• Stabbing, pricking, thorn-like pain in the heel
• Worst in the morning (first steps out of bed) or after prolonged rest - classic "post-static dyskinesia"
• Pain lessens with movement initially, then returns with prolonged standing or walking
• Tenderness at the medial calcaneal tuberosity on palpation
• Stiffness of the foot after inactivity
• In chronic/Kapha-dominant cases: mild swelling, heaviness, possible calcaneal spur on X-ray

Red Flags (consider alternative diagnosis)

• Bilateral heel pain - consider rheumatoid arthritis, ankylosing spondylitis, Reiter syndrome
• Pain in younger patients - consider calcaneal stress fracture
• Night pain, systemic symptoms - consider tarsal tunnel syndrome, osteomyelitis

Differential Diagnosis (Modern)

Treatment

Ayurvedic Treatments

• Heated metal probe (Panchadhatu Shalaka or Swarna Shalaka) applied to the most tender points of the heel
• Creates focal heat (Ushna, Tikshna guna) - counteracts Vata's cold/dry nature and breaks Kapha obstruction
• Done in multiple sittings; progressively reduces morning pain
• Considered the most effective Ayurvedic intervention for this condition, especially chronic cases

• Padabhyanga (foot massage with medicated oils like Mahanarayan taila, Ksheerabala taila)
• Vata-shamana (Vata-pacifying) property; reduces pain and stiffness

• Leech therapy or venesection at the site
• Reduces local inflammatory load

• Vata-pacifying formulations: Mahayogaraja guggulu, Rasnasaptaka kwatha, Dashamoola kashayam
• Basti (medicated enema) in systemic Vata vitiation

• Warm, unctuous (oily/ghee-rich) foods
• Avoid cold, dry, raw foods
• Warm water consumption
• Good supportive footwear
• Avoid prolonged standing, walking on hard/uneven surfaces

Modern Medical Treatment

• Plantar fascia stretching exercises - most evidence-based intervention
• Calf stretching (tight heel cord is a key risk factor)
• Ice/ice massage to the heel
• Heel cushioning / orthotic devices
• NSAIDs - for analgesia (not true anti-inflammation, as the condition is degenerative)
• Night splints - maintain stretch during sleep

• Corticosteroid injection - short-term relief; risk of plantar fascia rupture and fat pad necrosis with repeated injections
• Autologous blood injection / PRP - under investigation

• Extracorporeal shock wave therapy (ESWT) - mixed results
• Dry needling
• Physical therapy

• Partial plantar fascia release
