D. PROVISIONAL DIAGNOSIS
Try to give a complete diagnosis, such as:
  • This is a case of carcinoma of the left breast T2N1M0 (stage II) in a premenopausal woman
  • This is a case of obstructive jaundice probably due to carcinoma of head of the pancreas.
 
E. INVESTIGATIONS SUGGESTED
Investigations may be mentioned under the following headings:
  • Investigations for confirmation of diagnosis
  • Investigations to stage the disease (in case of a malignant disease)
  • Investigations to assess fitness of patient for anesthesia and surgery.
Investigations may also be mentioned under the following headings:
  • Base line investigations

    • Blood for sugar, urea and creatinine
    • Urine for routine examination
    • Stool for routine examination for ova/parasite/cyst
    • Chest X-ray (posteroanterior view)
    • 12-lead electrocardiogram.
  • Special investigations
    • Depends on the provisional diagnosis.
 
F. DIFFERENTIAL DIAGNOSIS
  • Write few relevant differential diagnoses. In list of differential diagnosis the more probable diagnosis should be written before the rare diagnosis.
In a long case examination: Examiner usually asks what is your case?
Then you should mention the summary of the patient and end up by giving the provisional diagnosis.
  • If the examiner asks you what is your diagnosis. Then straightway give a complete diagnosis.9
 
CLINICAL QUESTIONS ON GENERAL SURVEY
What are symptoms and signs?
Symptom is what the patient complains of and the sign is what the clinician elicits. Patient complains of pain at one site. When the clinician presses the area and patient experiences pain, this is tenderness. Pain is the symptom and tenderness is the sign.
How will you assess mental state?
While taking history try to make some initial assessment of the patient's intelligence, mental and emotional state. If the patient has been able to narrate the history well, cooperated with the clinician for the clinical examination patient may be considered conscious, alert, cooperative and oriented.
How will you assess performance status of the patient?
Originally performance status was assessed for consideration of patient fitness for administration of chemotherapy. This assessment of performance status may also be applied to surgical patient for assessing fitness for surgery and also to assess the surgical outcome.
There are two different ways for assessing the performance status:-
  • The Eastern Coopeartive oncology group (ECOG) performance status is as follows:
    Performance scale:
    • 0: Fully active and is able to carryout normal activities without any restriction.
    • 1: Symptoms restrict strenuous activity but is able to carryout light sedentary activities.
    • 2: Ambulatory but unable to carryout normal activities.. Up and about >50% waking hours.
    • 3: Only limited self care. Confined to bed for >50% of waking hours.
    • 4: Completely confined to bed, disabled, needs assistance.
    So ECOG performance status is written as.. score of 0, 1, 2, 3 or 4.
  • Karnofsky scale for performance status is as follows:
    • Able to carry on normal activity and to work; no special care needed (100–80).
      • 100: Normal no complaints; no evidence of disease.
      • 90: Able to carry on normal activity; minor signs or symptoms of disease.
      • 80: Normal activity with effort; some signs or symptoms of disease.
    • Unable to work; able to live at home and care for most personal needs; varying amount of assistance needed (70–50).
      • 70: Cares for self; unable to carry on normal activity or to do active work.
      • 60: Requires occasional assistance, but is able to care for most of his personal needs.
      • 50: Requires considerable assistance and frequent medical care.
    • Unable to care for self; requires equivalent of institutional or hospital care; disease may be progressing rapidly (40–0).
      • 40: Disabled; requires special care and assistance.
      • 30: Severely disabled; hospital admission is indicated although death not imminent.
      • 20: Very sick; hospital admission necessary; active supportive treatment necessary.
      • 10: Moribund; fatal processes progressing rapidly.
      • 0: Dead
Karnofsky performance status expressed as... score of 100, 90.............
10 How will you assess built or physique?
Built is the skeletal structure of an individual in relation to age and sex. Built may be described as short (Fig. 1.1), average or gigantism in comparison to a normal individual of the same age and sex.

What is Facies?
Observe the patient's face. The facial expression particularly the eyes indicate the facies of the patient. Some typical facies are thyrotoxic facies (Fig. 1.2A), facies of myxedema, moon facies of Cushing's syndrome (Fig. 1.2B), acromegaly (Fig. 1.2C), facies hippocratica, anxious facies, etc.

How will you assess gait?
Gait is observed while the patient walks. Patient examined in the bed is asked to sit, stand and then walk.
Decubitus or the Physical Attitude
Attitude of the patient in bed is called decubitus. Patient with abdominal pain due to peritonitis may lie still, while patient with colic may be restless and even roll with an attempt to get relief. Various neurological diseases may have characteristics posture. When the patient is comfortable in any position then the decubitus may be described as “decubitus of choice”.
How will you assess hydration status of the patient?
Assessment of the hydration status is important in surgical patient. Some diseases may cause chronic dehydration either due to failure of intake (dysphagia due to carcinoma esophagus) or excessive fluid loss due to Vomiting (gastric outlet obstruction) or diarrhea (ulcerative colitis or Crohn's disease). There may be evidence of fluid overload in patient with renal failure.
Hydration status is assessed by:
  • Look at tongue and oral mucosa—Normally moist. In case of dehydration will appear dry.
  • Pull the skin and release. Normal skin is elastic. In case of dehydration, the skin turgor will get lost (Figs 1.3A and B).
  • Patient will feel thirsty and urine output will also diminish.

12 How will you assess nutritional status of the patient?
Nutritional status is assessed by:
  • Calculating the body mass index.
  • Assessing the thickness of the subcutaneous fat in the arm, forearm or the back (Fig. 1.4A)
  • Assessing the bulk of the muscle by measuring the mid upper arm circumference (Figs 1.4B and C)
  • Look for any evidence of vitamin deficiency: skin changes (dermatitis), stomatitis, glossitis (Fig. 1.4D), etc.

What is body mass index?
Body mass index is calculated by:
  • Body mass index = Weight in kg/Height in sq meter.
    • Body weight—60 kg, height—1.5 metre.
    • 13Body mass index (BMI) + 60/2. 25 = 26. 6
    • Depending on the body mass index patient may be classified as:
      • Underweight
      :
      BMI—<18. 5
      • Normal
      :
      BMI—18. 5–24. 9
      • Overweight
      :
      BMI—25–29. 9
      • Obese
      :
      BMI—30 or higher
    • Nutritional state is described as poor, average or overnutrition.
    • In practical examination it may not be possible to measure BMI, unless you have a weighing machine and a height scale.
How will you assess anemia?
Anemia is quantitative or qualitative reduction of hemoglobin or red blood cell (RBC) or both in relation to standard age and sex.
Anemia is assessed by presence of pallor at the lower palpebral conjunctiva, tip and dorsum of the tongue, soft palate, nail beds and the skin on the palm and sole and the general body skin Figs 1.5A to D).

14Depending on the degree of pallor anemia is described as mild, moderate and severe anemia.
  • Mild anemia: When the hemoglobin is 50–60% of the normal
  • Moderate anemia: When the hemoglobin is 40–50% of normal
  • Severe anemia: When the hemoglobin is less than 40% of normal.
How will you assess jaundice?
Jaundice is defined as yellowish discoloration of skin, eyes and mucous membrane due to excessive bilirubin in blood. Jaundice is looked for in upper bulbar sclera, soft palate, undersurface of tongue, palms, soles and general body skin (Figs 1.6A to D).

Figure 1.6D: Look at the palm and soles
  • In deep jaundice there is yellowish hue of general body skin surface. Jaundice is also looked in general body skin surface, palms and soles
  • 15Normal bilirubin: Serum bilirubin value of 0. 2–0. 8 mg%
  • Latent jaundice: Serum bilirubin between 1 mg% 1. 9 mg%
  • Clinical jaundice is seen when the bilirubin level is more than 2 mg%.
What is cyanosis?
Bluish discoloration of the skin and mucous membrane due to excessive amount of reduced hemoglobin in circulation, i.e. more than 5 gm% of reduced hemoglobin in circulation. The cyanosis may be:
  • Peripheral cyanosis: Arterial oxygen saturation is normal but there is more oxygen desaturation at the veno-capillary bed. This may be due to peripheral vasoconstriction or sluggish circulation
  • Central cyanosis: This is due to excessive oxygen desaturation of the arterial blood.
Where will you look for cyanosis?
Peripheral cyanosis is looked for at tip of nose, ear lobule, tips of fingers and toes, and palms and soles. Central cyanosis is looked for in the tongue, inner surface of the lips in addition to the sites of peripheral cyanosis (Fig. 1.7).
How will you assess for presence of clubbing?
  • Look at the nail from the side to look for increased curvature of the nail (Fig. 1.8A) and assessment of angle between the nail and nail bed
  • Look for fluctutation at the base of the nail with two index fingers (Fig. 1.8B).
  • Look for Schamroth sign (Fig. 1.8C).

zoom view
Figure 1.8A: Look at the nail from the side
zoom view
Figure 1.8B: Fluctuation at the base of the nail with two index fingers
Clubbing is characterized by increase in transverse and longitudinal curvature of the nail with increase of the angle between the nail and the nail bed (Lovibond's angle) (Fig. 1.8D). This is 16also associated with bulbous changes and diffuse enlargement of the terminal phalanges. These changes are due to proliferation of subungual connective tissues.
What is Schamroth's sign?
When the nail of two normal fingers are apposed there is a diamond shaped gap. In clubbing this diamond shaped gap disappears. This is known as Schamroth sign (Fig. 1.8C).
zoom view
Figure 1.8C: Schamroth sign
What is Lovibond angle?
When the nail is viewed from the side, the skin fold of the nail and the base of the nail makes an angle known as Lovibond angle. Normally this angle is less than 165 degrees. In case of clubbing the angle between the skin of the nail fold and the base of the nail is more than 180 degrees (Fig. 1.8D).
zoom view
Figure 1.8D: Lovibond angle
What are the degrees of clubbing?
1st degree: There is only increased fluctuation of the nail bed.
2nd degree: In addition to fluctuation, there is increased anteroposterior and transverse diameter of the nail.
3rd degree: Above changes with increased pulp tissue in the terminal phalanges.
4th degree: Combination of above changes with subperiosteal thickening of bones of wrist and ankle (hypertrophic osteoarthropathy).
Where will you look for presence of edema?
edema is defined as excessive accumulation of fluid in the extravascular compartment.
In ambulant patient, edema is looked for by pressing on the medial surface of the tibia about 2. 5 cm above the medial malleolus for about 5–10 seconds. If edema is present a dimple will appear in the skin (Figs 1.9A and B).

How will you assess jugular venous pressure?
The jugular venous pressure reflects the hemodynamics of the right atrium. Patient is made to lie supine with head end propped up to about 45° and the upper level of the jugular venous pulsation is localized by the clinician looking from the side (Fig. 1.10). The height of the upper point of jugular venous pulsation measured from the level of the sternal angle in centimeter is the jugular venous pressure (Fig. 1.11).
zoom view

Figure 1.11: Measurement of the height of jugular venous pressure
In normal individuals, the jugular venous pressure does not exceed 2 cm vertically above the sternal angle. The jugular venous pressure is elevated in patients with congestive heart failure and in superior mediastinal syndrome.
What are the characteristics of jugular venous pulsation wave?
Normal jugular venous pulse wave is characterised by both positive and negative waves. a, c, and v are positive waves and x and y are negative waves (Fig. 1.12).
18a wave: Due to right atrial contraction.
c wave: Due to impingement of carotid artery into the jugular vein during systole.
x wave: Due to atrial diastole reulting in fall of right atrial pressure.
v wave: Due to right atrial filling.
y wave: Due to opening of tricuspid valve resulting in emptying of right atrium.

What are the different lymph node groups in the neck?
Depending on the location of the lymph nodes in relation to the investing layer of deep cervical fascia the cervical lymph nodes may be:
  • Superficial: Lymph nodes lying superficial to the investing layer of the deep cervical fascia
  • Deep: Lymph nodes lying deep to the investing layer of deep cervical fascia
  • These lymph nodes may further be subdivided into horizontal chain and vertical chain.
What are the different levels of lymph nodes in the neck?
There are six levels of lymph nodes in the neck (Fig. 1.13)
Level I: Submental lymph nodes lying in the submental triangle (IA) and submandibular lymph nodes situated in the submandibular triangle (IB).
Level II (Upper Jugular Group): Lymph nodes located around the upper third of the internal jugular vein from the level of carotid bifurcation to the base of the skull.
Level III (Middle Jugular Group): Lymph nodes located around the middle third of the internal jugular vein extending from the carotid bifurcation above to the cricothyroid membrane below.
Level IV (Lower Jugular group): Lymph nodes located around the lower third of the internal jugular vein lying between the cricothyroid membrane above and the clavicle below.
Level V (Posterior Triangle Group): Lymph nodes located in the posterior triangle extending laterally up to the anterior border of the trapezius and medially up to the lateral border of sternomastoid. The supraclavicular nodes are also included in this group.
Level VI (Anterior Compartment Group): This includes the perilaryngeal, pericricoid and peritracheal nodes lying above up to the hyoid bone, below up to the suprasternal notch, and laterally extend up to the medial border of sternomastoid.
(Lymph nodes in the anterior mediastinum is included as level VII nodes).

What is Virchow's gland?
The left supraclavicular lymph node lying between the two heads of sternocleidomastoid is called the Virchow's lymph node. This lymph node may be involved by metastasis from carcinoma 19of stomach, testicular tumor, carcinoma of esophagus and bronchogenic carcinoma (Fig. 1.14).
zoom view

How will you palpate the cervical lymph nodes?
The cervical lymph nodes may be palpated both from front and the back.
The clinician stands behind the patient. The neck is slightly flexed and turned to the side of examination. The different groups of lymph nodes levels I to VI are then palpated systematically with one hand.
  • Level IA lymph nodes are palpated at the submental triangle with the pulp of the fingers directed upwards with the neck slightly flex and turned to the same side (Fig. 1.15A)
  • Similarly level IB nodes are palpated at the submandibular triangle (Fig. 1.15B)

How will you examine pulse?
Pulse is the lateral expansion of the arterial wall due to a column of arterial blood forced into the arteries by the contraction of the heart.
21Palpate the radial pulse just above the wrist on the anterior aspect of the lower end of the radius lateral to the tendon of the flexor carpi radialis (Fig. 1.16)
Look for rate, rhythm, volume, tension, condition of arterial wall, equality of pulse with the opposite radial and femoral pulses, any special character of the pulse.
Regarding rate:
  • Normal heart rate: It is 60–100 beats per minute, average 72 beats per minute
  • Bradycardia: Heart rate less than 60 beats per minute
  • Tachycardia: Heart rate more than 100 beats per minute
  • Relative bradycardia: When there is fever, there is rise of pulse rate. for each degree rise of temperature and there is rise of 10 beats per minute. When with per degree rise of temperature, the pulse rate increase is less than 10 beats per minute then it is called relative bradycardia, e. g. enteric fever (1st week)
  • Relative tachycardia: With per degree rise of temperature, the pulse rate rise is more than 10 beats per minute, e. g. rheumatic carditis.
zoom view
Figure 1.16: Palpation of radial pulse
Regarding rhythm: Appearance of successive pulse waves with time:
  • Normal rhythm: The successive pulse beats are appearing at definite intervals
  • Irregular rhythm: The successive pulse beats are not appearing at definite interval. This may be
    • Irregularly irregular
    • Successive beats are appearing at irregular intervals or the rhythm may be occasionally interrupted by a slight irregularity coming at definite interval
    • Regularly irregular.
How would you assess volume of pulse?
The amplitude of the pulse is defined as the pulse volume and is palpated with the fingers. This may be normal, low volume or high volume depending on the amplitude of the pulse wave.
How will you assess tension of the pulse wave?
Tension of pulse is defined as the pressure required to obliterate the pulse wave.
How will assess the condition of the arterial wall?
Empty the segment of the artery by using two middle fingers and then palpate with the two fingers and try to roll the artery against the bone. The arterial wall may be thickened in atherosclerosis (Figs 1.17A to C).

How will you measure blood pressure?
Blood pressure is measured by sphygm­omanometer (Fig. 1.18).
The patient lies supine in the bed. The blood pressure cuff is wrapped around the arm firmly and evenly around the arm one inch above the elbow joint, with the middle of the rubber bag lying over the brachial artery. The blood pressure cuff is then inflated till the radial pulse disappears. The diaphragm of the stethoscope is placed over the brachial artery under the edge of the sphygmomanometer cuff taking care not to press the diaphragm too heavily over the brachial artery.
zoom view
Figure 1.18: Measurement of blood pressure
The blood pressure cuff is then deflated gradually and listen with the stethoscope when clear tapping sound becomes first audible. This is the point which indicates systolic blood pressure. The cuff is continually deflated. The character of the audible sounds changes and the sound becomes muffled and then disappears. This is the point which indicates diastolic blood pressure.
The blood pressure may also be measured by palpatory method. The blood pressure cuff is inflated till the radial pulse disappears. The cuff is then deflated slowly. The point at which the radial pulse reappears is the systolic blood pressure. The cuff is then continually deflated and the radial pulse assumes a water hammer character and then suddenly resumes the normal character. The point at which pulse resumes normal character indicates diastolic blood pressure.
What is hypertension?
Persistent systolic blood pressure above 140 mm Hg and diastolic blood pressure above 90 mmHg is defined as hypertension.
What is hypotension?
Persistent systolic blood pressure below 90 mmHg is defined as hypotension.
23 How will you assess respiration?
Normal respiration is abdominothoracic and the normal rate is 18–20 breaths per minute. Allow the patient to take normal breathing and observe the rate of respiration by noting the movement of chest and abdomen in one minute. Look for rhythm of respiration and any special type of respiration. Note whether the respiration is thoracic, abdominal or abdominothoracic.
What is Cheyne-Stokes breathing?
This is a special type of respiration, when there is a period of hyperpnea followed by apnea. The respiration becomes deeper and deeper until a peak is reached when there is apnea followed by hyperpnea. The period of hyperpnea lasts for 1–3 minutes, whereas the period of apnea lasts for 10–30 seconds.
This type of respiration is usually found in patients with increased intracranial pressure, renal failure and morphine poisoning.
How will you measure temperature?
Temperature is measured by clinical thermometer and is expressed in either Fahrenheit or Centigrade scale. In surgical case, temperature is not recorded routinely.
  • Normal body temperature: 98–99°F
  • Subnormal temperature: Below 98°F
    zoom view
    Figure 1.19: Types of fever
  • 24Pyrexia: Above 99°F
  • Hyperpyrexia: Above 106°F
  • Hypothermia: Below 95°F.
Types of fever (Fig. 1.19):
  • Continuous fever: The daily fluctuation of temperature is less than 1. 5°F and the temperature does not touch the baseline. It is found in pneumococcal pneumonia, in second week of enteric fever and rheumatic fever
  • Remittent fever: The daily fluctuation is more than 2°F and the temperature does not touch the baseline. This is found in urinary tract infection and pulmonary tuberculosis
  • Intermittent fever: Fever continues for several hours and returns to normal during the day. This may be:
    • Quotidian: The paroxysm of intermittent fever occurs daily
    • Tertian: The paroxysm of intermittent fever occurs on alternate days
    • Quartan: The paroxysm of intermittent fever occurs every three days
    • Relapsing fever: There cyclic periods of fever and periods of apyrexia.
What is Pel-Ebstein fever?
This is a type of relapsing fever when there is fever for a period of 14 days and there is apyrexial period of 14 days. Found in Brucellosis and Hodgkin's lymphoma.
What do you mean by pyrexia of unknown origin (PUO)?
When a fever of more than 101°F persists for more than 2 weeks with the cause remaining obscure in spite of intensive investigations is called pyrexia of unknown origin.
Where do you look for pigmentation?
The usual sites to be looked for pigmentation are face, oral cavity, tongue, creases of palms and soles and general body skin. Pigmentation may be seen in Cushing's syndrome, Addison's disease, Peutz-Jeghers syndrome (Figs 1.20A and B) and other dermatological diseases.

CLINICAL QUESTIONS
How will you examine temperature over the swelling?
The temperature of the swelling is ascertained by palpation with the dorsum of the fingers. Compare the temperature over the swelling with the temperature of the adjacent area or corresponding area of the body (Fig. 1.22).
zoom view
Figure 1.22: Ascertaining temperature over the swelling
How to ascertain tenderness over the swelling?
Press the swelling with the pulp of the fingers and look at the patient face. If the patient experiences pain on pressure, tenderness is said to be present.
How will you measure the size of the swelling?
The size of the swelling on inspection is assessed approximately and expressed in centimeter.
During palpation the margins of the swelling are marked and the swelling is measured with a tape. If the swelling is spherical the measurement of diameter is sufficient. In other swelling measure the length and breadth of the swelling and express in centimeter (Fig. 1.23A to C). Ideally the size of the swelling should be measured by using a vernier calliper.

Figures 1.23B and C: In elongated swelling measure the length and breadth of the swelling
28 How will you examine the surface of the swelling?
Palpate with the pulp of the finger over the surface of the swelling. The surface of the swelling may be smooth, irregular (The irregular surface may be granular, nodular or lobulated) (Fig. 1.24).
How will you assess the margin of the swelling?
Palpate the periphery of the swelling with the pulp of the finger (Figs 1.25A and B).
The margin of the swelling may be well defined (When it can be palpated well) or illdefined when the margins are not delineated well on palpation.
The margin of the swelling may be regular (when it is uniform throughout) or irregular (when the periphery of the swelling is not uniform).

Figures 1.25A and B: Ascertaining the margin of the swelling
How will you assess underlying bony indentation?
Some swelling like long standing dermoid cyst may show bony indentation.
Palpate at the periphery deep to the margin of the swelling. If there is bony indentation the raised bony margin can be felt deep to the margin of the swelling (Fig. 1.26).
zoom view
Figure 1.26: Palpation for ascertaining underlying bony indentation
How will you assess consistency of the swelling?
Press the swelling with the pulp of the finger and assess the feel (see Fig. 1.24).
The consistency of the swelling may be:
  • Soft (Feel of a relaxed muscle) or
  • 29Firm (Feel of a contracted muscle).
  • Hard (Feel of bone).
  • The consistency of a swelling may be described as variegated when the swelling has a variable feel soft, firm or hard at different parts of the swelling.
How will you demonstrate fixity of the swelling to skin?
Try to pick up the skin from the underlying swelling (Fig. 1.27). If the skin can be picked up from the swelling, the swelling is not fixed to skin. If the skin cannot be picked up from the swelling, the swelling is said to be fixed to the skin. The malignant swelling may infiltrate the skin and the overlying skin may be fixed to the swelling.
zoom view
Figure 1.27: Demonstration of skin fixity. The skin can be picked up from the swelling
How will you ascertain relation of the swelling with the underlying muscle?
A swelling may lie either superficial or deep to the muscle or it may arise from the muscle itself.
Ask the patient to contract the muscle. If the swelling becomes more prominent, the swelling lies superficial to the muscle (Figs 1.28A and B). If the the swelling becomes less prominent, it lies deep to the muscle. If the swelling remains same or becomes less prominent and becomes immobile, it may arise from the muscle.
zoom view
Figures 1.28A and B: Ascertaining relation of a chest wall swelling to the underlying pectoralis major muscle. The swelling is first examined with the muscle relaxed. Patient is then asked to contract the pectoralis major muscle—the swelling becomes more prominent with the muscle contracted—suggesting that the swelling lies superficial to the pectoralis major muscle
How will you ascertain fixity of the swelling to the underlying muscle?
A swelling may become fixed to the underlying muscle or bone. Before testing for fixity of the swelling to the muscle it is necessary to exclude whether swelling is fixed to the underlying bone or not.
30Hold the swelling and try to move it with the underlying muscle relaxed both along and across the axis of the muscle (Figs 1.29A and B).
If the swelling is immobile with the muscle being relaxed, this indicates that the swelling is fixed to the underlying bone. It is not necessary now to ask the patient to contract the muscle and test for fixity of the swelling to the muscle. The swelling has to be fixed to the underlying muscle as it fixed to the underlying bone.
If the swelling is mobile with the muscle relaxed, this indicates the swelling is not fixed to the underlying bone.
Ask the patient to contract the muscle (confirmed by palpating the contracted muscle), and try to move the swelling over the contracting muscle in both axes (Fig. 1.29C).
If the swelling is freely mobile, this indicates that the swelling is not fixed to the underlying muscle.
Restriction of mobility of the swelling over the contracted muscle indicates fixity of the swelling to the underlying mscle.
zoom view
Figures 1.29A and B: Ascertaining fixity of the swelling with the underlying muscle. The swelling is moved with the muscle relaxed. The swelling is mobile—suggesting that the swelling is not fixed to the underlying bones and prevertebral fascia
zoom view
Figure 1.29C: The right sternocleidomastoid muscle is contracted by asking the patient to look to the opposite side against resistance and the mobility is tested again. if the mobility remains same, then the swelling is not fixed to the underlying sternocleidomastoid muscle, If the mobility becomes restricted—the swelling is fixed to the underlying muscle
How will you demonstrate fluctuation?
Fluctuation means transmitted impulse in two planes at right angles to each other.
Depending on the size of the swelling one finger or two fingers of each hand is used to demonstrate fluctuation. The finger which presses the swelling is called the displacing finger while the static fingers, which appreciate the displacement is called the watching finger.
31Usually index and middle fingers straight with slight flexion at metacarpophalangeal joint are placed over the swelling. The tip of the pulp of the left index middle finger is placed halfway between the center and the periphery of the swelling. This is the watching finger and is kept static throughout the procedure. The tip of the pulp of the right index and middle finger is placed at similar point diagonally opposite the right index and middle finger. This is the displacing finger.
The displacing fingers are pressed inward, if the watching fingers are displaced by this pressure in both axes of the swelling then fluctuation is said to be positive (Figs 1.30A and B).
In small swelling, the two fingers of the left hand are placed apart over the swelling and this acts as the watching finger. The right index finger acting as the displacing finger exerts pressure at the center of the swelling. If the watching finger is displaced in both axes of the swelling then fluctuation is said to be positive (Fig. 1.30C).
zoom view
Figures 1.30A and B: Demonstration of fluctuation
zoom view
Figure 1.30C: Demonstration of fluctuation in small swelling
In small swelling the fluctuation may be demonstrated by Paget's test. The swelling is fixed at the periphery with two fingers and feel the swelling from centre to the periphery. The swelling feels softer at the center than at the periphery.
In case of a mobile swelling, the swelling should be fixed by an assistant and the fluctuation demonstrated by the above method.
If the swelling is very small (less than 2 cm), it is difficult to demonstrate fluctuation.
32 How will you differentiate transmitted and expansile pulsation?
Place the index and middle finger over the swelling. If the pulsation is transmitted, the fingers move up parallel to each other with each pulsation. If the pulsation is expansile, the fingers are lifted up and also move apart with each pulsation (Figs 1.31A to C).
The transmitted pulsation is present when there is a swelling in front of an artery. Expansile pulsation is present in cases of an aneurysm.
zoom view
Figures 1.31A to C: (A) Demonstration of transmitted and expansile pulsation. (B) both the fingers are lifted up. (C) The fingers are both lifted up and moved apart
How will you demonstrate transillumination?
The transillumination is usually demonstrated by placing a torch over the swelling and usually under the shade of a screen. The normal skin transillumination should be taken into account before commenting that the swelling is transilluminant.
The important brilliantly transilluminant swelling includes:
  • Vaginal hydrocele
  • Cystic hygroma
  • Encysted hydrocele of the cord
  • Hydrocele in the canal nuck
  • Congenital hernia in infants may show positive transillumination.
How will you demonstrate that the swelling is compressible?
When the swelling is compressed with the fingers it diminishes in size and may disappear completely and when the pressure is released, it reappears slowly (Figs 1.32 and 1. 33).
Hemangiomas, lymphangiomas and meningocele or meningomyelocele are com­pressible.

What do you mean by indentation of a swelling?
Press the swelling for 15–30 seconds. if a dimple appears over the swelling then the swelling is said to have shown the sign of indentation (Figs 1.34A to D).
Cysts containing pultaceous materials as in dermoid cyst or sebaceous cyst are said to be indentable.
