Assessment on Sexually Transmitted Disease

Assessment of Sexually Transmitted Infections (STIs/STDs)

Sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs), are infections transmitted predominantly through sexual contact (vaginal, anal, and oral intercourse). Certain STIs may also be transmitted via blood, shared needles, or from mother to child. Etiological agents include bacteria, viruses, parasites, protozoa, and rarely fungi. Manifestations may involve the genitals, urethra, anus, rectum, pharynx, conjunctiva, or skin; many infections remain asymptomatic for extended periods.

A systematic, non-judgmental, and patient-centered approach is essential when assessing individuals for possible STIs.

The assessment comprises four core components:
• Comprehensive sexual & medical history
• Physical examination
• Diagnostic investigations
• Patient education and counseling

Common Clinical Presentations

• Abnormal genital, urethral, vaginal, or rectal discharge
• Dysuria (burning or pain on urination)
• Genital sores, ulcers, vesicles, blisters, warts, or rashes
• Genital or perianal pruritus
• Lower abdominal or pelvic pain (especially in females)
• Scrotal pain, swelling, or tenderness
• Dyspareunia
• Intermenstrual or post-coital bleeding
• Enlarged/tender lymph nodes
• Pharyngeal discomfort or exudates
• Systemic symptoms (fever, rash, arthralgia)

Note: Many STIs (e.g., chlamydia, gonorrhea in women, HPV) are asymptomatic; screening is indicated in high-risk groups even without symptoms.

Comprehensive Sexual and Medical History

Key elements to cover confidentially and empathetically:

• Presenting complaint and timeline of symptoms
• Number and gender of sexual partners (past 6–12 months and lifetime)
• Types of sexual practices (oral, vaginal, anal; insertive/receptive)
• Consistency of condom/barrier use
• Symptoms or known STIs in partner(s)
• Date of last sexual contact and last unprotected exposure
• Previous STI history and treatment completion
• Drug use (especially stimulants linked to high-risk behavior)
• History of sexual assault or coercion
• Contraceptive method, last menstrual period, pregnancy history (women)
• Cervical screening and vaccination status (HPV, Hep A & B)
• Travel history and general medical/medication history

Physical Examination

General Examination

• Vital signs, weight, pallor, jaundice
• Skin and mucous membranes (rashes, lesions)
• Lymph node palpation (cervical, axillary, inguinal)
• Oral and pharyngeal inspection

Genitourinary & Anorectal Examination

• Inspection: External genitalia, urethral meatus, retraction of foreskin (males), speculum exam (females when tolerated), perianal region
• Palpation: Inguinal nodes, bimanual pelvic exam, Bartholin/Skene glands, scrotal contents, digital rectal exam if indicated

Important: Defer speculum/bimanual exam in suspected sexual assault or when severe pain/ulceration is present.

Diagnostic Investigations

• Serology: HIV Ag/Ab (4th gen), syphilis (RPR/VDRL + TPHA/FTA-ABS), hepatitis B & C
• NAAT (preferred): First-void urine or vaginal/rectal/oropharyngeal swabs for Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Mycoplasma genitalium
• Lesion swabs: HSV PCR, syphilis PCR/dark-field
• Other: Wet mount, Gram stain, Pap smear/HPV co-test, pelvic ultrasound (if PID suspected)

Patient Education and Counseling

• Consistent and correct condom use (male/female condoms, dental dams)
• Reduction in number of sexual partners or mutual monogamy
• Regular STI screening, especially <25 years or with new/multiple partners
• Completion of full treatment course and abstinence until cured
• Partner notification and simultaneous treatment
• Vaccination: HPV (up to age 45 where indicated), hepatitis A & B
• Avoid vaginal douching and unnecessary antibiotics
• Offer PrEP or doxy-PEP where guidelines recommend
• Psychosocial support and referral as needed

A holistic, patient-centered approach combining accurate diagnosis, effective treatment, and compassionate education is key to reducing STI transmission and promoting sexual health.

Chest Pain - Differential Ciagnosis Chart

Chest Pain – Differential Diagnosis Chart

Clinical Guidance

This chart provides a quick reference for differentiating common causes of chest pain. Always consider patient history, risk factors, and conduct appropriate diagnostic tests for accurate diagnosis.

Feature	Cardiac (Angina / MI)	Gastrointestinal (GERD, Esophageal spasm)	Pulmonary (PE, Pleurisy, Pneumonia)	Musculoskeletal (Costochondritis, Trauma)
Location	Sub-sternal / Retro-sternal / Mediastinum	Sub-sternal (burning, retrosternal)	Localized (lateral or pleuritic), may radiate anteriorly	Anterior chest wall (localized)
Quality	Heavy, squeezing, crushing, choking	Burning, sharp, "heartburn-like"	Sharp, stabbing, pleuritic	Aching, sharp, tender on palpation
Radiation	Neck, jaw, left shoulder, left arm, forearm, ring finger	Rare, sometimes back (esophagus)	Rare	None (localized only)
Onset	Sudden (MI) or exertional (angina)	After meals, lying flat, spicy food	Sudden (PE) or gradual (infection)	After movement, strain, trauma
Duration	Angina < 5 min, MI > 20 min	Variable (minutes–hours)	Variable (depends on cause)	Hours–days
Relation with Respiration	No relation	No relation	Worse with inspiration/cough	Worse with movement / pressure
Relief	Rest, O₂, nitrates	Antacids, proton pump inhibitors	Rest, analgesics, treatment of cause	Rest, NSAIDs, local heat
Other Clues	Sweating, nausea, palpitations, dyspnea	Acid reflux, regurgitation, sour taste	Fever, cough, dyspnea, hemoptysis (PE)	Local tenderness, reproducible pain

Key Clinical Takeaways

• Cardiac pain = retrosternal, heavy, radiating, not affected by breathing/movement.
• Gastro pain = burning, post-meal, relieved by antacids.
• Pulmonary pain = pleuritic, sharp, worse with breathing/cough.
• Musculoskeletal pain = localized, reproducible by palpation/movement.

Important Note

This chart is for educational purposes only. Always perform a thorough clinical assessment and use appropriate diagnostic tools. Cardiac causes should be ruled out first in patients with chest pain, especially those with risk factors.

Hallmark Signs

🩺 Hallmark Signs Decoded!

How they differ from Cardinal & Classic Signs – With Real Clinical Examples

✨ Hallmark Signs & Symptoms

These are the most distinctive, defining features of a disease — so unique that their presence often points directly to a diagnosis.

• They may not be present in every case, but when seen, they're highly suggestive.
• Think of them as the "smoking gun" of a condition.
• Often used in differential diagnosis to narrow down possibilities.

🌟 Real-Life Hallmark Examples:

• Pulmonary Edema: Frothy pink sputum — a hallmark sign of fluid-filled lungs.
• Multiple Sclerosis: Babinski sign (upgoing toe) + optic neuritis + ataxia — classic triad.
• Acute Pancreatitis: Grey Turner’s sign (flank bruising) or Cullen’s sign (periumbilical bruising).
• Myasthenia Gravis: Ptosis (drooping eyelid) and diplopia (double vision) worsened by fatigue.
• Systemic Lupus Erythematosus (SLE): Malar rash (butterfly-shaped facial rash) + photosensitivity.
• Hypercalcemia: “Stones, bones, groans, moans” — but the hallmark is bone pain due to resorption.
• Cushing’s Syndrome: Moon face, buffalo hump, purple striae — especially the central obesity.
• Diabetic Ketoacidosis (DKA): Kussmaul breathing (deep, rapid breathing) — a hallmark compensatory mechanism.

💡 Pro Tip: A hallmark sign doesn’t need to be in every patient — but if you see it, think: “This disease just became more likely.”

✅ Cardinal Signs

These are the essential, non-negotiable symptoms required to diagnose a condition — part of formal diagnostic criteria.

• Missing one may prevent diagnosis.
• Used in guidelines like DSM-5, ICD-11, and WHO standards.
• More rigid than hallmark signs.

🎯 Cardinal Examples:

• Diabetes Mellitus: Polyuria, polydipsia, polyphagia, weight loss.
• Depression (DSM-5): Depressed mood OR anhedonia + ≥4 other symptoms (sleep, appetite, energy, etc.).
• Chronic Obstructive Pulmonary Disease (COPD): Chronic cough, sputum production, dyspnea on exertion.
• Alzheimer’s Disease: Progressive memory loss + cognitive decline + functional impairment.

📚 Classic Signs

These are the textbook, traditional presentations taught in medical school — historically famous, but not always seen today.

• May be outdated or rare in modern practice.
• Great for teaching, but beware over-reliance.
• Use as a reference, not a rule.

📚 Classic Triads & Signs:

• Charcot’s Triad: Right upper quadrant pain, jaundice, fever — classic for cholangitis.
• Reynolds’ Pentad: Charcot’s triad + hypotension + altered mental status — severe cholangitis.
• Triad of Parkinson’s: Tremor, rigidity, bradykinesia.
• Wernicke’s Triad: Confusion, ophthalmoplegia, ataxia — vitamin B1 deficiency.
• “Hirsutism, Amenorrhea, Obesity” in PCOS — a classic presentation, though not all patients have all three.

⚠️ Caution: Not every patient fits the "classic" picture. Always look beyond textbooks!

🧠 Quick Comparison

Hallmark: The "aha!" moment — distinctive & diagnostic.

Cardinal: The "must-have" criteria — required for diagnosis.

Classic: The "textbook image" — helpful, but not universal.
