Clinical Skills
The general examination represents your first hands-on patient encounter, functioning as a clinical detective scanning for vital clues. Significant diagnostic information can be gathered through systematic observation before specialized examination begins.
🎯 The Big Picture: The Art of Observation
Systematic Patient Assessment
Fundamental Principles:
🎯 Holistic Assessment
- Evaluate the patient as a complete person
- Primary tools: eyes, ears, and nose
- Begin observation immediately upon entering
🎯 Early Clues
- Handshake quality and strength
- Gait pattern when rising from chair
- Posture and body positioning
- May reveal neurological/musculoskeletal issues
Critical First Question: "Does this patient look ill?" Trust your clinical intuition—this sense sharpens with experience but provides valuable initial diagnostic direction.
😷 The Head-to-Toe Reconnaissance
Facial Assessment & Spot Diagnoses
Facial Expression Analysis:
- Pain indicators: grimacing, tension
- Anxiety signs: worried expression, restlessness
- Fear manifestations: wide eyes, tense posture
Characteristic Disease "Faces":
🎯 Parkinsonism
- Fixed, staring "mask-like facies"
- Reduced blinking frequency
- Soft, hypophonic speech
🎯 Hyperthyroidism
- "Startled" or worried appearance
- Prominent, staring eyes (exophthalmos)
- Lid lag and retraction
🎯 Acromegaly
- Coarse, enlarged facial features
- Prominent nose and jaw
- Thickened lips and large hands
🎯 Myxoedema (Severe Hypothyroidism)
- Puffy, dull facial appearance
- Dry skin texture
- Thinning of lateral eyebrows
- Clinical Pearl: Changes often gradual and easily missed
🎯 Cushing's Syndrome
- Round "moon face"
- Facial plethora (redness)
- Flushed complexion
🎯 Down Syndrome
- Upward-slanting palpebral fissures
- Flat nasal bridge
- Characteristic facial profile
👁️ General Body Clues & Systemic Signs
Whole-Body Assessment
Weight Loss Indicators:
🎯 Physical Signs
- Baggy, ill-fitting clothing
- Loose belt notches
- Gaping collar space
🎯 Differential Clues
- Chronic Illness (TB/Cancer): Wasted, unwell appearance
- Anorexia Nervosa: "Perky" demeanor despite emaciation
- Hyperthyroidism: Restless, fidgety with weight loss
Anaemia Assessment:
🎯 Reliable Examination Sites
- Palmar creases (blanching assessment)
- Conjunctiva (lower eyelid inspection)
- Nail bed color and capillary refill
🎯 Diagnostic Confirmation
- Critical: Only haemoglobin level provides definitive diagnosis
- Clinical signs are suggestive, not diagnostic
Other Diagnostic Clues:
🎯 Chronic Alcohol Use
- Facial flushing and plethora
- Fine hand tremor
- Alcohol odor on breath
🎯 Tobacco Smoking
- Nicotine-stained fingers (index/middle)
- Characteristic tobacco odor
- Tar-stained teeth
👃 Skin, Sounds, and Smells
Multisensory Diagnostic Clues
Skin Pigmentation Patterns:
🎯 Generalized Pigmentation
- Chronic systemic illness
- Addison's disease (bronze tan, including palmar creases)
🎯 Patchy Depigmentation
- Vitiligo (autoimmune association)
- Linked with thyroid disease, pernicious anemia
Abnormal Movement Patterns:
🎯 Parkinson's Disease
- Slow, "pill-rolling" resting tremor
- Bradykinesia and rigidity
🎯 Liver Failure
- Asterixis ("liver flap")
- Coarse, flapping tremor with wrist extension
🎯 Hyperthyroidism
- Fine tremor of outstretched hands
- Increased amplitude with stress
Diagnostic Sounds & Odors:
🎯 Voice Quality
- Hoarseness: laryngitis or recurrent laryngeal nerve lesion
- Myxoedema: slow, deep, "thick" speech
🎯 Characteristic Breath Odors
- DKA: Sweet, fruity acetone odor
- Liver Failure: Sweet, musty foetor hepaticus
- Uremia: Ammonia-like odor
👐 The Hands: Diagnostic Goldmine
Comprehensive Hand Examination
Color Assessment:
🎯 Palmar Pallor
- Suggests anaemia
- Compare with patient's normal baseline
🎯 Palmar Erythema
- Redness of palms (especially thenar/hypothenar eminences)
- Liver disease or hyperthyroidism association
Shape & Structure Abnormalities:
🎯 Dupuytren's Contracture
- Palmar fascia thickening
- Flexion contracture of fingers
- Strong association: Chronic liver disease
🎯 Arachnodactyly
- Long, spider-like fingers
- Marfan syndrome characteristic
- Assess with wrist and thumb signs
Clubbing Assessment:
🎯 Progressive Stages
- Stage I: Spongy nail bed fluctuation
- Stage II: Loss of nail bed angle (>165°)
- Stage III: Increased nail curvature
- Stage IV: Bulbous finger appearance
🎯 Major Causes
- Lung cancer and bronchiectasis
- Cyanotic heart disease
- Inflammatory Bowel Disease (IBD)
- Cirrhosis and thyroid disease
Nail Pathology:
🎯 Koilonychia
- Spoon-shaped, concave nails
- Classic for severe iron deficiency
🎯 Nail Pitting
- Small depressions in nail plate
- Psoriasis characteristic finding
🎯 Splinter Haemorrhages
- Tiny linear blood streaks
- Possible infective endocarditis sign
🎯 Leuconychia
- White nail discoloration
- Hypoalbuminaemia association
