GENERAL PHYSICAL EXAMINATION
GENERAL PHYSICAL EXAMINATION INTRODUCTION The general examination should follow the same three principles as any other element of the diagnostic process: (what are the aims of performing general physical exam?) 1.to establish or refute diagnostic hypotheses generated by the history 2 .to screen for important abnormalities 3. to satisfy patient requests for reassurance When undertaking a physical examination the following rules should be considered: 1-keep the patient comfortable and relaxed. 2-explain what you are going to do. 3-warm environment is essential. 4-consider privacy of the patient. 5-optimal (preferably natural) lighting. 6-examine exposed parts of the body or undress the patient down to underclothes and cover him with a sheet or blanket. 7-expose both sides when examining paired structures in order to compare the diseased with normal. 8-the examiner stands on the right side of the patient. 9-examination time should be short especially in ill patients and in emergencies. 10-interpret findings as you go along. PROCEDURE: - Introduce yourself and explain the procedure. Ensure the patient is comfortable and maintain the patient’s dignity. -Look at the patient from the end of the bed: Does the patient prefer a fixed position(eg: knees up, bending forward etc) ? -Introduce these as localising signs and concept of pain being enhanced by tissue tension -Patient lying rigid or restless? Classical position adopted to ease pancreatic pain (patient with chronic pancreatitis) The general examination should contain the following elements: 1-General impression: -age -sex -built: signs of weight loss -looks: well, ill, in pain or depressed… -hydration -state of hygiene 2-Mental status: -consciousness and orientation (to time, place and persons) Glasgow Coma Scale (GCS) -restlessness, anxiety ,sweating ,apathy ,depression ,rapid breathing , speech 3-Abnormal facies and body configuration : Down’s,Turner’s and Marfan’s syndromes,acromegaly,Cushing’s syndrome,Hippocratic facies ,myxoedema and thyrotoxicosis, parkinsonism and renal failure. Face:pallor,anaemia,cyanosis.oedema,jaundice,polycythaemia. Cushing’s syndrome (moon face ) hypothyriodism Acromegaly Down's syndrome Marfans Syndrome 4-Eyes : pupils , exophthalmos , ptosis , squint , eye movements , conjunctiva (anaemia), sclera (jaundice) Exophthalmos One of the eye signs of thyrotoxicosis 5-Hands : sweating , temperature , size , deformity , pallor , cyanosis , erythema , nicotine stains, tremor. Nicotine- stained fingers of a chain smoker Paronychia Vitiligo It is often autoimmune in origin Dupuytren´s contracture The acromegalic hand is large with wide long fingers Leprosy The muscle wasting is due to peripheral nerve damage Palmar erythema of a patient with chronic liver failure Rheumatoid Thrombophlebitis arthritis deformity 6-Nails: brittled , clubbing , pallor of anaemia and hypoalbuminaemia , splinter haemorrhages , spoon shaped , paronychia , Beau’s lines, Mei’s lines. Koilonychia it indicates iron deficiency Beau's lines Onychomycosis Fungal infection of the nails 7-Skin: skin of the palm of the hand (erythema) , colour of skin creases , spider naevi, laxity of the skin , bruising , skin nodules and moles , ulcers , Osler’s nodes , Dupuytren’s contracture 8-Hair 9-Mouth: -halitosis (foetor oris) ,special mouth odores (diabetic keto acidosis, renal and hepatic failure ,alcohol smell. oral candidiasis , angular stomatitis, tongue : hydration, congenital abnormalities , tumours , anaemia , central cyanosis , jaundice , vitamine deficiency , hydration , tongue atrophy,smooth tongue , ulceration (aphthous ulcers) , inflammation (glossitis) , coating , size of the tongue , tongue movement. Aphthous ulcer . Carcinoma of the tongue Macroglossia of acromegaly Leukoplakia 10-Lymphadenopathy 11-Leg oedema. Pallor The pallor of anaemia is noticeable in the following areas: 1- mucous membranes. 2- The inner surface of the lower lid . 3- Palm and palmar creases. Jaundice: Is a yellowish discoloration of the skin and mucous membranes due to excess circulating bile pigments . Mild degrees of jaundice are easily picked up by staining of the sclera As jaundice becomes more pronounced there is yellow discoloration of the skin and this may progress to yellow/orange or even dark brown with high levels of plasma pigment. Cyanosis: Is blue discoloration given to the skin by deoxygenated blood. However,a minimum of 5g/dl is required to produce visible cyanosis;it is thus not detectable in severe anaemia. Cyanosis is difficult to elicit in dark-skinned people with anaemia. A-Peripheral cyanosis: bluish discoloration of the skin of fingernails and ear lobes in the presence of normal oxygen saturation ,it occurs due vasoconstriction caused by cold. B-Central cyanosis: bluish discoloration of the lips and tongue due to excess of deoxygenated blood . It occurs in the following conditions: 1-Respiratory abnormalities: chronic obstructive airways disease. 2-Mismatched arterial ventilation and perfusion : pulmonary embolism;pulmonary shunts; AV fistula. 3-Hypoventilation: head injuries; drug overdosage. 4-Cardiac conditions: congenital abnomalies with right-to-left shunt. 5-High altitude. Pitting oedema Unilateral leg oedema Facial oedema Raccoon eyes a sign for basal skull fracture The Hippocratic facies in diffuse terminal peritonitis Port Wine Stain Laxity With aging skin becomes thinner and loses its elasticity Angular stomatitis with cracking and fissuring of the lips: A feature of vitamin deficiency Acanthosis nigricans Cutaneous pigmentation & thickening associated with an underlying malignancy. Vitiligo An autoimmune destruction of melanocytes
