CLINICAL SURGERY, I found while searching
on internet so , I hoped you ge benefit from ... Just I hope !!!!!
Q. What is your diagnosis?
A. Subcutaneous lipoma.
Q. Why this is a lipoma?
A. Because it is a very slowly growing swelling which is soft, pseudofluctuant with a slippery edge.
Q. Why the edge of the lipoma is slippery ?
A. Because it is present within a very loose capsule so that pressure on one edge moves the swelling within the capsule.
Q. Why the lipoma is pseudofluctuant ?
A. Because the fat globules constituting the lipoma are very soft in consistency.
Q. How do you elicit fluctuation in a very small swelling ?
A.
By Paget's test; the swelling is fixed by the index and thumb of the
left hand and pressure is applied on the center of the swelling by the
index of the right hand. If there is yeilding in the center of the
swelling, it is considered fluctuant.
Q. Why this is a subcutaneous and not a subfascial lipoma ?
A.
Because it is attached to the skin at multiple sites while in
subfascial lipoma the skin is not attached to the swelling at all. Also,
making the fascia tense does not make the swelling smaller.
Q. How did you detect the skin attachment ?
A. There are two methods to detect skin attachment; either by pinching or by gliding
Q. Mention the different sites of lipoma ?
A. 1. Subcutaneous lipoma
2. Subfascial lipoma,
3. Intermuscular lipoma
4. Intramuscular lipoma
5. Subperiosteal,
6. Subserous lipoma,
7. Extradural lipoma
8. Retroperitoneal lipoma
9. Subsynovial
10. Intraglandular
Q. Which site is famous for being precancerous ?

9. Multiple Keloids
10. Multiple Boils
11. Multiple Skin Metastases
Q. What is the commonest multiple skin swelling ?
A. Multiple naevi.
Q. How do you treat this patient ?
A.
The treatment of lipoma is usually conservative. Excision is indicated
if 1) cosmetically annoying the patient , 2) complicated, 3) painful,
or 4) causing pressure on a surrounding structure.
Q. What are the complications of a lipoma ?
A.
Pressure on a surrounding structure e.g. a retroperitoneal lipoma
compressing the ureters, hindering the movement of a nearby joint,
calcification, myxomatous degeneration, and very rarely malignant
transformation (liposarcoma).
Q. What is Dercum's disease ?
A. It is a painful lipoma, also called "adiposa dolorosa".
Case 2. HAEMANGIOMA
Q. What is your diagnosis ?
A. Cavernous haemangioma of the ......(mention the site).........
Q. Why this is a haemangioma ?
A. Because it is a skin swelling dating since birth (may be shortly after), it is pink in color and compressible.
Q. Why the haemangioma is compressible ?
A.
Haemangioma consists of multiple blood-filled vascular spaces. These
spaces communicate with the surrounding veins. Haemangioma is
compressible because its contained blood empties into the veins
communicating with the haemangioma.
Q. What are the compressible swellings you know ?
A.

Q. What do you mean by embolization injection ?
A.
That is the injection of some material into the feeding artery of the
haemangioma through angiography to produce occlusion of this artery and
so necrosis of the haemangioma.
Q. What are the famous materials to be used in this regard ?
A. Gelfoam, alcohol foam and silicon particles.
Q. What is a hamartoma ?
A.
A hamartoma is "a developmental tumour-like malformation characterized

Oral Questions on a Case of Hernia
Case 1. INGUINAL HERNIA
Q. What is your diagnosis ?
A. Rt. oblique inguinal hernia, uncomplicated, containing intestine (omentum), no other hernias, no predisposing factors.
Q. Why this is a hernia ?
A.
Because 1) It is a swelling, 2) At the anatomical site of a hernia, 3)
Gives an impulse on cough, and 4) It is (or was) reducible on lying
down and by the patient fingers.
Q. Why inguinal and not a femoral hernia ?
A.
Because 1) the hernia is above the inguinal ligament and not below it,
and 2) the neck of the hernia is above and medial to the pubic
tubercle and because the hernia descends into the scrotum.
Q. Why oblique and not direct ?
A.
Because 1) it descends into the scrotum, 2) On doing the internal ring
test, there was no swelling to appear on coughing, and 3) the patient
is a young male.
Q. Describe how did you do the internal ring test ?
A.
After reduction of the hernia, the patient is asked to stand while
occluding the internal ring (by pressing the finger 1/2 an inch above
the mid inguinal point), the patient is then asked to cough, observing
the appearance of any inguinal swelling.
Q. Why you did not do the external ring test ?
A. Because it is painful.
Q. Can a direct hernia descend into the scrotum ?
A. A direct hernia can reach the scrotum very rarely.
Q. Where is the defect in oblique inguinal hernia ?
A. In the internal ring.
Q. Where is the defect in direct inguinal hernia ?
A. The posterior wall of the inguinal canal (Hasselbach's triangle).
Q. What are the boundaries of Hasselbach's triangle ?
A.
Lateral border of the rectus abdominis muscle medially, the inferior
epigastric artery laterally and the inguinal ligament inferiorly.
Q. What are the subdivisions of the Hasselbach's triangle ?
A. Hasselbach's triangle is subdivided into medial and lateral parts by means of the medial umbilical ligament.
Q. What are the common contents of a hernia in general ?
A. Intestine, omentum and fluid.
Q. Mention the clinical types of oblique inguinal hernias ?
A. 1) Bubonocoele, 2) Funicular type and 3) Scrotal (complete) type
- Bubonocoele = Hernia is only in the groin.
- Funicular type = Hernia descends into the scrotum but the testis is felt separate from the hernial sac.
- Scrotal
(complete) type = Hernia descends into the scrotum and the hernial sac
surrounds the testis which is not felt through the contents of the
hernia.
A. Hydrocoele of the hernial sac : Part of the sac near its neck becomes encysted by a piece of omentum and accumulates fluid.
A.
Hernia of hydrocoele : In cases of vaginal hydrocoele, a defect occurs
in the dartos fascia of the scrotum through which a part of the
hydrocoele herniates.
Q. What are the causes of residual swelling after reducing the hernia ?
A.
1) Sliding hernia , 2) incomplete reducibility due to adhesions
between the contents and the sac , 3) hydrocoele of the hernial sac and
4) associated lipoma of the cord
Q. How would you clinically differentiate between obstructed and strangulated hernias ?
A.
- # This is difficult because both are very acute conditions with the hernia being painful, irreducible & tender.
- # Impulse on cough is preserved in obstructed but is lost in strangulated hernias.
- # The hernia is tense in strangulation but not in obstruction.
- # Symptoms and signs of intestinal obstruction are present in obstructed hernias and maybe present in strangulated hernis
- # The degree of shock and toxaemia are more severe in strangulated hernias.
- #
However, both conditions are considered surgical emergencies and
necessitate an urgent interference to relieve the cause of
strangulation and to deal with the contents
An enterocoele can be obstructed and can be strangulated while an
omentocoele can only be strangulated as it has no lumen to be
obstructed.
Q. What are the conditions that you may find strangulation without obstruction ?
A. If the content of the hernia is one of the following :
1. Omentum
2. Part of the circumference of the intestinal lumen (Richter's hernia)
3. Michael's diverticulum (Littre's hernia)
4. Fallopian tube & ovary
5. Intestine, but there is an associated mesenteric vascular occlusion
Q. What is the treatment of this case of oblique inguinal hernia ?
A.
- O.I.H. in children and adolescents -----------> Inguinal herniotomy
- O.I.H. in adults --------------------------> Inguinal herniorrhaphy
- O.I.H. in elderly and recurrent cases --------> Inguinal hernioplasty
A. Inguinal herniotomy, that is excision of the hernial sac. They do not need repair as they have very good muscles
Q. What is the principle of operation for O.I.H. in adults?
A. Excision of the sac + repair of the defect
Q. What are the principles of such repair ?
A. Repair of the defect is done either by the local tissues (herniorrhaphy) or by adding a graft of tissue (hernioplasty).
The principles in both herniorrhaphy and hernioplasty, in general, are the following ;
1. Narrowing the internal ring,
2. Repair of the fascia transversalis, and;
3. Reinforcement of the posterior wall of the inguinal canal.
Q. What is the most popular type of repair ?
A. Bassini repair.
Q. What is its principle ?
A. Suturing the conjoined muscle to the inguinal ligament.
Q. What are the causes of recurrence of a hernia ?
A.
- 1.
Untreated preoperative condition : Chronic straining (asthmatic
bronchitis, prostatic enlargement ....etc.), debility, obesity - 2. Intraoperative causes: Improper haemostasis, tense repair, lax repair, repair with absorbable suture material
- 3. Postoperative causes : Haematoma, infection, early return to hard work

1) Supraumbilical
2) Infraumbilical
Q. Is it common for patients with PUH to complain of dyspepsia ?
A. Yes.
Q. Why ?
A. Due to traction on the greater omentum which is commonly the content of such a hernia.
Q. What is the commonest complication of paraumbilical hernia ?
A. Irreducibility, due to marked adhesions between the contents.
Q. What is the danger of such irreducibility ?
A. It predisposes to obstruction and strangulation.
Q. What is the treatment of this case ?
A. Herniorrhaphy.
Q. What type of repair do you do ?
A. It varies according to the size of the defect as follows :
A.
In paraumbilical hernia, the defect is close to the umbilicus so that
the umbilicus forms a crescent at the edge of the sac, while in
epigastric hernia, there is a bridge of normal abdominal muscles between
the defect and the umbilicus. Besides, epigastric hernia could be
multiple
Q. What are the causes of incisional hernia
A. There are;
Case 1. PRIMARY VARICOCOELE
Q. What is your diagnosis ?
A. Left primary varicocoele.
Q. Why this is varicocoele ?
A. Because there is an inguinoscrotal swelling characterized by ;
* By inspection : Varicose veins are seen just beneath the skin of the scrotum (bag of worm appearance)
*
By palpation : There are multiple soft, compressible swellings with
impulse and thrill on cough. They decrease in size on lying down and
disappear on elevation of the scrotum.
Q. What is the definition of varicocoele ?
A. It is dilatation, elongation, and tortuosity of the pampiniform plexus of veins.
Q. What are the types of varicocoele ?
A. Primary and secondary varicocoele.
Q. How does hypernephroma produce secondary varicocoele ?
A. By extension of tumour thrombus into the renal vein leading to obstruction of the testicular vein.
Q. On which side is 2ry varicocoele more common and why ?
A.
On the left side, because the left testicular vein drains into the
renal vein, while the right testicular vein drains into the inferior
vena cava. So, 2ry varicocoele on the left side occurs when there is
tumour thrombosis of the left renal vein, whereas on the right side,
thrombosis should extend to the IVC to occlude the right testicular
vein.
Q. Why 1ry varicocoele is more common on the left side ?
A. Because of the following reasons :
A. 1. Recurrent attacks of thrombophlebitis.
2. 2ry hydrocoele.

By grasping the neck of the scrotum by two fingers; the thumb infront
and the index finger behind the neck, it was found that the swelling is
completely below the fingers.
Q. How did you know that it is a cystic swelling ?
A.
By doing the bipolar fluctuation test ; One hand's fingers are placed
around the neck of the scrotum, and the other hand's fingers hold the
bottom of the swelling. The latter squeezes the swelling where an
impulse is perceived by the other hand's fingers at the top of the
swelling.
Q. What are the values of transillumination in hydrocoele ?
A.
It differentiates between hydrocoele which is translucent and other
opaque cysts. It also localizes the testis in case of vaginal
hydrocoele.

A. It varies according to the size of the defect as follows :
- Very small defect ---------> Anatomical repair
- Small to Moderate defect ---------> Mayo's repair
- Moderate to Large defect ---------> Hernioplasty (prolene mesh graft)
A.
In paraumbilical hernia, the defect is close to the umbilicus so that
the umbilicus forms a crescent at the edge of the sac, while in
epigastric hernia, there is a bridge of normal abdominal muscles between
the defect and the umbilicus. Besides, epigastric hernia could be

thyroid gland, pretracheal L.N., cold abscess of the larynx,
parathyroid gland tumours, laryngocoele and tracheocoele.
Q. When doesn't the goitre move up and down with deglutition ?
A. In 1) Huge goitre, 2) Malignant goitre and 3) Retrosternal goitre.
Q Why this is a simple goitre ?
A.
Because there are no manifestations suggestive of thyrotoxicosis, no
manifestations suggestive of malignancy and no manifestations
suggestive of inflammation.
Q. What are the manifestations suspicious of malignancy in a goitre ?
A.
A.
By fixing the trachea by one hand and trying to move the gland up and
down with the other hand, normally there is a slight range of movement.
Q. How do you elicit fixity to the sternomastoid ?
A.
By asking the patient to swallow while pinching the relaxed
sternomastoid, normally I do not feel something pulling on the
sternomastoid between my fingers.
Q. Can the cervical L.Ns. develop secondaries from a thyroid carcinoma while the 1ry is not felt clinically ?
A.
Yes, in occult papillary carcinoma of the thyroid gland. This was
thought in the past as some form of ectopic thyroid gland and was
called "lateral aberrant thyroid".
Q. What are the manifestations suspicious of an inflammatory goitre ?
A.
A.
Simple goitre is due to stimulation of the thyroid gland by increased
level of circulating T.S.H. secondary to low levels of circulating
thyroid hormones secondary to either iodine deficiency or defective
synthesis of thyroid hormones.
Q. What are the causes of iodine deficiency ?
A.
A.
1) Enzymatic deficiency, and 2) Goitrogens (Cabbage, P.A.S.,
antithyroid drugs and iodides in large amounts "iodide goitre")
Q. What is Pendred's syndrome ?
A. This is a cretinoid goitre associated with deafness.
Q. What is the cause of this goitre ?
A. Congenital deficiency of peroxidase enzyme.
Q. What are the types of simple goitre ?
A. 1. Simple diffuse goitre (Physiological goitre)
2. Simple nodular goitre (S.N.G.).
Q. Which of them is reversible ?
A. Physiological goitre can be reversible if the cause of iodine defeciency is eliminated.
Q. What are the complications of simple nodular goitre ?
A.
1) Pressure on surrounding structures (dyspnoea and dysphagia), 2)
Disfigurement, 3) 2ry toxic goitre (30%), 4) Haemorrhage in a cyst, and
5) Malignant transformation (1/2%), {Follicular Type}.
Q. How does a patient with a haemorrhage in a cyst present ?
A. Sudden onset of dyspnoea.
Q. What is the cause of dyspnoea in such cases ?
A. Sudden enlargement of the gland and more important is the reflex spasm of the pretracheal muscles.
Q. How do you manage such a patient ?
A. Emergency needle aspiration.
Q. What investigations do you want to do for this patient with a goitre ?
A. In addition to the routine laboratory investigations, we do thyroid function tests.
Q. What are the complications of subtotal thyroidectomy for S.N.G.?
A. Complication of subtotal thyroidectomy for S.N.G. include :
A. It can lead to suffocation as it is enclosed within the pretracheal muscles.
Q. How do you treat it ?
A.
First, urgently, while the patient is in bed, the sutures are cut to
relieve the tension and the patient is taken to the theatre to deal with
the bleeder.
Q. What are the causes of dyspnoea after thyroidectomy ?
A.
1) Tension haematoma, 2) Laryngeal oedema due to rough manipulations
during the operation, 3) Bilateral recurrent laryngeal nerve injury,
and 4) Tracheomalacia (very rare).
Q. What are the effects of RLN injury ?
A.
&Unilateral
RLN injury -------------> hoarseness of voice which is improved by
time due to compensatory crossing of the contralateral cord to the
other side.
&Bilateral RLN injury -------------> Suffocation which should be treated at once by emergency tracheostomy.
Q. What is the effect of external laryngeal nerve injury ?
A. Loss of high pitched voice due to paralysis of cricothyroid muscle..
Case 2. TOXIC GOITRE[/b]
Q. What is your diagnosis ?
A1. Toxic diffuse goitre (1ry toxic goitre)
A2. Toxic nodular goitre (2ry toxic goitre)
Q. Why this is a goitre ?
A.
Because there is a swelling in the lower part of the front of the neck
which is the anatomical site of the thyroid gland, having the shape of
the thyroid gland (butterfly) and this swelling moves up and down with
deglutition.
Q. Why it is toxic ?
A. Because the patient has manifestations of thyrotoxicosis in the form of:
A.
1. Infrequent blinking (staring look)
2. Apparent rim of sclera above the cornea.
3. Lid lag : the upper lid does not follow the eyeball on looking down.
4. Absence of forehead corrugation on looking upwards
5. Absence of convergence on looking to anear object
6. Exophthalmos : A. Apparent exophthalmos B. True exophthalmos
7. Tremors of the eyelids
Q. What is the pathogenesis of each of these eye signs ?
A.
#
Infrequent blinking, apparent rim of sclera above the cornea, lid lag
and apparent exophthalmos are all due to upper eyelid retraction which
is caused by spasm of MullerÕs muscle (thyroxine makes this
muscle oversenstised to the effect of circulating catecholamines).
# Absence of forehead corrugation is caused by true exophthalmos.
# Absence of convergence on looking to a near object is due to paresis of the medial recti.
#
True exophthalmos is due to exophthalmos producing substance which
causes deposition of oedema fluid and round cell infiltration in the
retro-orbital space.
Q. How to differentiate between true & apparent exophthalmos ?
A. By 1) Naffziger's test; 2) Frazer's test; 3) Ruler test (See clinical notes for details of these tests)
Q. Define hyperthyroidism and thyrotoxicosis.
A.
Hyperthyroidism is the term referred to the manifestations caused by
the increased level of circulating thyroid hormones. Thyrotoxicosis is a
syndrome consisting of manifestations caused by the increased level of
circulating thyroid hormones as well as others that are not due to
increased level of circulating thyroid hormones (Exophthalmos and
Pretibial myxoedema).
Q. What are the types of toxic goitre ?
A. There are three types
1) Toxic diffuse goitre (1ry toxic goitre) (Grave's disease)
2) Toxic nodular goitre (2ry toxic goitre) (Plummer's disease)
3) Toxic nodule.
Q. Are there other causes of thyrotoxicosis ?
A. Yes. the following are rare causes of thyrotoxicosis :
1. Thyrotoxicosis factitia : Due to intake of thyroxine (e.g. for weight reduction)
2. Infantile thyrotoxicosis : A baby born to a thyrotoxic mother
3. Jod Basedow disease : Due to high intake of iodides in a colloid goitre
4. De Quervain thyroiditis (in some cases)
5. Hashimoto thyroiditis (in early cases)
6. Some tumours secrete thyroxine e.g. struma ovarii.
Q. How do you treat a case of toxic nodular goitre (2ry toxic goitre) ?
A. Subtotal thyroidectomy.
Q. How would you prepare a case of toxic goitre for operation ?
A. 1. Antithyroid drugs e.g. Neomercazole until the patient is euthyroid,
2. Propranolol (Inderal) for regulation of heart rate,
3. Lugol's Iodine
Q. When do you contraindicate antithyroid drugs in preop. preparation ?
A. In retrosternal goitre.
Q. Why ?
A. Because antithyroid drugs cause enlargement of the thyroid gland which may lead to mediastinal syndrome.
Q. What is Lugol's iodine ?
A. It is 5% iodine and 10% KI in water.
Q. What is its mechanism of its action ?
A. 1) Inhibition of protease enzyme which releases thyroid hormones from thyroglobulin,
2) Inhibition of organic iodine formation,
3) Prevention of the stimulant effect of TSH on adenyl cyclase enzyme.
Q. What is the principle of subtotal thyroidectomy in toxic goitre ?
A.
Subtotal Thyroidectomy = Removal of both lobes + Isthmus, Leaving
postero-medial part of the lobes on each side to protect the recurrent
laryngeal nerve and parathyroid glands.
Q. What are the complications of subtotal thyroidectomy for toxic goitre ?
A. 1. Tension haematoma (due to slipped ligature from the superior thyroid artery).
2. Dyspnoea.
3. Injury to the related nerves : i) recurrent laryngeal nerve, and ii) external laryngeal nerve .
4. Thyrotoxic crisis.
5. Hypoparathyroidism (due to accidental removal of the parathyroid glands).
6. Hypothyroidism in 20-30% (if the gland was removed near totally).
7. Recurrent thyrotoxicosis in 5-10% (If no adequate excision is done).
Q. What is thyrotoxic crisis ?
A. It is an acute exacerbation of hyperthyroidism. It occurs if the patient is not adequately prepared for thyroidectomy.
Q. What are the manifestations of thyrotoxic crisis ?
A. Hyperpyrexia, restlessness, severe tachycardia, and dehydration.
Q. Is it a dangerous condition ?
A. Yes it is. Severe tachycardia may lead to heart failure and hyperpyrexia may lead to brain damage.
Q.What are the indications of antithyroid drugs in toxic nodular goitre ?
A.
A. No, radio-iodine is ineffective in toxic nodular goitre because of the fibrosis present in the gland.
Q. How do you treat a case of toxic nodule ?
A.
Surgery (hemithyroidectomy) is the main line of treatment. Medical
treatment is indicated in preoperative preparation, in young patients
and in patients refusing surgery or unfit for surgery. Radio-iodine can
be given to patients over 45 years as an alternative to surgery.
Q. What is the mechanism of action of radioactive iodine in the treatment of toxic goitre ?
A.
Radioactive iodine emits beta rays which destroys the thyroid cells
without affecting much the surrounding tissue due to their low
penetrability.
Q. What type of radioactive iodine is given in the treatment of toxic goitre ?
A. I 131.
Q. Why I131 and not I123 ?
A. Because I131 can emit beta rays while I123 can emit only gamma rays which are ineffective.
Q. What is the dose of radioactive iodine in treatment of toxic goitre ?
A. 10 uCi (10 micro Curi).
Q. What are the disadvantages of radioactive iodine ?
A. 1. Isotope facilities must be present.
2. Indefinite follow up is essential.
3. Thyroid insufficiency in 80% after 10 years.
4. Recurrence of toxicity if low dose is given.
5.
Risk of inducing carcinoma in adults if given in childhood or
adolescence (that is why it is not given for patients below 45 years).
6. Risk of hypothyroidism and foetal anomalies if given in pregnancy.
Q. What are the contraindications to radio-iodine ?
A. 1. During pregnancy (risk of foetal anomalies and foetal hypothyroidsm).
2. During lactation (risk of hypothyroidsm to the baby).
3. Young age (risk of inducing thyroid carcinoma).
4. Toxic nodular goitre (ineffective). 5. Iodine allergy.
Q. What is the advantage of radio-iodine in a case of toxic nodule ?
A. No, because the thyroid tissue surrounding the toxic nodule is suppressed and so will not uptake iodine.
Case 1. SIMPLE NODULAR GOITRE
Q. What is your diagnosis ?
A. Simple nodular goitre.
Q. Why this is a goitre ?
A.
Because there is a swelling in the lower part of the front of the neck
which is the anatomical site of the thyroid gland, having the shape of
the thyroid gland (butterfly) and this swelling moves up and down with
deglutition.
Q Why does a goitre move up and down with deglutition ?
A.
Because the thyroid gland is enclosed within the pretracheal fascia
which is attached to the thyroid cartilage and hyoid bones.
Q. Mention other swellings that move up and down with deglutition.
A.
Subhyoid bursitis, prelaryngeal L.Ns., thyroglossal cyst, ectopic
thyroid gland, pretracheal L.N., cold abscess of the larynx,
parathyroid gland tumours, laryngocoele and tracheocoele.
Q. When doesn't the goitre move up and down with deglutition ?
A. In 1) Huge goitre, 2) Malignant goitre and 3) Retrosternal goitre.
Q Why this is a simple goitre ?
A.
Because there are no manifestations suggestive of thyrotoxicosis, no
manifestations suggestive of malignancy and no manifestations
suggestive of inflammation.

- In
acute and subacute thyroiditis : Short duration, pain, may be fever
(with or without chills), warmth and tenderness over the gland. - In
Hashimoto thyroiditis : Locally the gland is very similar to S.N.G.
but the course of the disease is characteristic; early there is
thyrotoxicosis which is followed by hypothyroidism. - In
Riedle's thyroiditis : The gland is irregularly enlarged, hard, fixed
to skin, trachea, and sternomastoid i.e. very similar to anaplastic
carcinoma of the thyroid gland.

Oral Questions on a Case of Leg Ulcer
Case 1. POST-TRAUMATIC LEG ULCER
Q. What is your diagnosis ?
A. A chronic post-traumatic (non-specific) leg ulcer in the (mention the region) of the Rt./Lt. leg.
Q. Why did you diagnose it non specific ulcer ?
A. Because it has the following characters (in addition to a history of severe trauma) :
A.
It is caused by wounds, burns, corrosives, radiation or traumatic
gangrene including bedsore (decubitus ulcer), plaster sores and direct
crushes.
Q. Why this type of ulcer has the tendency to become chronic ?
A.
It becomes chronic being maintained by repeated trauma, pyogenic
infection and poor blood supply from congestion caused by long sitting
or standing.
Q. What is indolent ulcer ?
A.
In very chronic ulcers with excess fibrosis base and edge become hard
(callous) and such an ulcer resists healing and is called indolent
ulcer.
Q. What are the investigations required in this case ?
A.
Plain X ray tibia to show any bony involvement, culture and
sensitivity to give the specific antibiotic, Biopsy from the edge to
confirm the diagnosis. This is in addition to the routine
investigations.
Q. What is the treatment of this case ?
A.
1.
Conservative treatment : This is indicated in small ulcers, provided
that they are not indolent. (i.e. not callous). Conservative treatment
includes : rest, elevation of foot, avoid long sitting or standing,
frequent dressings, pressure bandage, and antibiotics if indicated
(according to culture and sensetivity).
2.
Surgery : It is indicated in 1) large ulcers, 2) indolent ulcers.
Surgery includes excision of the ulcer and covering the defect by a
skin flap.
Q. Why do you prefer a skin flap as the method of coverage ?
A.
Because skin grafts in the leg have the tendency to re-ulcerate
(venous congestion, poor blood supply, frequent traumata,...)
Q. What are the characters of venous ulcer ?
A.
Over the medial malleolus; surrounded by pigmentation, dermatitis,
scaly skin and leg oedema; sloping edge; floor shows healthy or
unhealthy granulations which may be raised, flat or below surface;
indurated base, and serous or pus discharge.
Q. What is the aetiology of this type of ulcers ?
A. It is caused by 1ry or 2ry varicose veins but more commonly with 2ry V.V (in postphlebitic limbs following D.V.T.).
Q. What are the trophic ulcers ?
A. These are ulcers due to impaired nutrition of the skin. They include both ischaemic ulcers and neurotrophic ulcers.
Q. What is chronic osteomyelitis ulcer ?
A. It Develops at outer opening of osteomyelitis sinuses. There are multiple sinuses discharging sequestra.
Q. What are the malignant ulcers that can develop in the leg ?
A. Malignant leg ulcers include :
A. This is very rare because of the severe fibrosis surrounding the ulcer
Oral Questions on a Case of Cleft Lip & Palate
Case 1. CLEFT LIP
Q. What is your diagnosis ?
A. Unilateral incomplete simple cleft lip not associated with cleft palate.
Q. What do you mean by incomplete ?
A. The cleft is not reaching the nostril floor.
Q. What do you mean by simple ?
A. There is no associated cleft of the alveolar margin.
Q. Did you hear about cleft lower lip ?
A. It is an extremely rare anomaly it is characterized by being median in position.
Q. What are the types of cleft palate you know ?
A.
Cleft uvula, cleft soft palate, incomplete cleft palate (Cleft soft
and hard palate not reaching the alveolar margin), Complete cleft
palate. Incomplete and complete cleft palate could be unilateral or
bilateral.
Q. What do you mean by uni or bilateral cleft palate ?
A. It depends on whether the mouth cavity is communicating with one or the two nasal cavities.
Q. When do you repair cleft lip ?
A. At about the age of 3 months.
Q. Why this age specifically ?
A.
It is preferred not to do the operation before this age because at
that age the Hb% is almost 10 gm% and the weight of the child is almost
10 bounds and this is optimum and safe for anasthesia (in other words,
the operation before this age is rather risky).
On
the other hand, the operation is preferred not to be delayed after
that age for the following reasons : 1) for the proper development of
teeth, 2) for psychological relief of the parents' worry about their
child and 3) for proper suckling (although the role played by the lip
in suckling is not that considerable if compared with that of the
palate).
Q. What is the principle of any operation described for the repair of cleft lip ?
A. The principles for any repair of cleft lip are :
1. To bypass the defect : by suturing the muscles, skin and mucous membrane (3 layer closure)
2. To lengthen the lip : by interpositioning of flaps from both sides adjusting all esthetic points.
Q. What is the commonest operation for the repair cleft lip ?
A. Millard repair.
Q. Why not to do freshening and direct suture without the need to do rotation and advancement flaps ?
A.
This direct suture would produce what is called "a lip notch" because
of the shortening of the lip at the edges of the cleft.
Q. What are the complications of cleft palate ?
A. 1) Malnutrition due to improper suckling.
2) Repeated chest infection due to aspiration from regurgitated food and water
3) Speech abnormalities
4) Otitis media due to Eustachean tube obstruction by oedema around its mouth.
Q. What is the cause of improper suckling in cleft palate ?
A. Failure to create an intraoral negative pressure.
Q. What are the speech abnormalities encountered in cleft palate ?
A. 1) Nasal tone of speech (Rhinolalia) and 2) Inability to pronounce some syllables like K, L, Q.
Q. At what age do you prefer to repair cleft palate ?
A.
The repair of the most anterior palate can be done during the same
operation of repair of the cleft lip, while the remaining posterior
palate is repaired at about the age of 11/2 to 2 years.
Q. Is it preferred to postpone the operation after the age of 2 years ?
A. No, because the speech abnormalities of the cleft palate become irreversible (Imprinted in the brain).

Oral Questions on a Case of Hypospadias
Case 1. DISTAL SHAFT HYPOSPADIAS
Q. What is your diagnosis ?
A. Distal shaft hypospadias.
Q. What other types of hypospadias do you know ?
A. Glandular, coronal, midpenile, posterior penile, penoscrotal, scrotal and perineal hypospadias.
Q. What are other deformities that can be seen in the penis ?
A. 1) The prepuce is incomplete on the ventral aspect, being represented as a dorsal hood,
2) Chordee may be present especially in the posterior types.
3) There may be meatal stenosis.
4) The penis may be smaller in size (microphalus)
5) May be deviation of the median raphe.
Q. What are the associated anomalies that can be seen in the testis and scrotum ?
A. 1) Incompletely descended testis.
2) Split scrotum.
Q. What is chordee ?
A. It is the ventral curvature of the penis on erection.
Q. What is the principle of treatment of hypospadias ?
A.
Two things : 1) To correct (to release) the chordee (if present) by
excision of the fibrous tissue causing this chordee. 2) To replace the
missing urethra (urethroplasty)
Q. When do you prefer to repair hypospadias ?
A. Before school age, between 4 to 5 years.
Q. Why this age in particular ?
A.
The repair is better not to be delayed after the age of school because
the child develops psychological disturbances if he was admitted to
school while he has hypospadias. On the other hand, before this time,
the penis is not that developed to allow the operation to be done
easily.
Q. How do you explain the psychological disturbances in hypospadias in school age children ?
A.
Due to the abnormal direction of the stream of urine, the child sprays
urine on his clothes which makes him feels guilty and shy.
Case 1. POST-TRAUMATIC LEG ULCER
Q. What is your diagnosis ?
A. A chronic post-traumatic (non-specific) leg ulcer in the (mention the region) of the Rt./Lt. leg.
Q. Why did you diagnose it non specific ulcer ?
A. Because it has the following characters (in addition to a history of severe trauma) :
- Site : It is commonest over shin of tibia
- Size : Any size
- Shape : Rounded, oval or irregular
- Edge : Sloping edge
- Floor : shows healthy or unhealthy granulations which may be raised, flat or below surface
- Base : Indurated, may be fixed to the underlying bone
- Margin : May be pigmented
- Discharge : Serous or pus discharge
- Draining LNs. : Usually show secondary lymphadenitis
A.
It is caused by wounds, burns, corrosives, radiation or traumatic
gangrene including bedsore (decubitus ulcer), plaster sores and direct
crushes.
Q. Why this type of ulcer has the tendency to become chronic ?
A.
It becomes chronic being maintained by repeated trauma, pyogenic
infection and poor blood supply from congestion caused by long sitting
or standing.
Q. What is indolent ulcer ?
A.
In very chronic ulcers with excess fibrosis base and edge become hard
(callous) and such an ulcer resists healing and is called indolent
ulcer.
Q. What are the investigations required in this case ?
A.
Plain X ray tibia to show any bony involvement, culture and
sensitivity to give the specific antibiotic, Biopsy from the edge to
confirm the diagnosis. This is in addition to the routine
investigations.
Q. What is the treatment of this case ?
A.
1.
Conservative treatment : This is indicated in small ulcers, provided
that they are not indolent. (i.e. not callous). Conservative treatment
includes : rest, elevation of foot, avoid long sitting or standing,
frequent dressings, pressure bandage, and antibiotics if indicated
(according to culture and sensetivity).
2.
Surgery : It is indicated in 1) large ulcers, 2) indolent ulcers.
Surgery includes excision of the ulcer and covering the defect by a
skin flap.
Q. Why do you prefer a skin flap as the method of coverage ?
A.
Because skin grafts in the leg have the tendency to re-ulcerate
(venous congestion, poor blood supply, frequent traumata,...)
Q. What are the characters of venous ulcer ?
A.
Over the medial malleolus; surrounded by pigmentation, dermatitis,
scaly skin and leg oedema; sloping edge; floor shows healthy or
unhealthy granulations which may be raised, flat or below surface;
indurated base, and serous or pus discharge.
Q. What is the aetiology of this type of ulcers ?
A. It is caused by 1ry or 2ry varicose veins but more commonly with 2ry V.V (in postphlebitic limbs following D.V.T.).
Q. What are the trophic ulcers ?
A. These are ulcers due to impaired nutrition of the skin. They include both ischaemic ulcers and neurotrophic ulcers.
Q. What is chronic osteomyelitis ulcer ?
A. It Develops at outer opening of osteomyelitis sinuses. There are multiple sinuses discharging sequestra.
Q. What are the malignant ulcers that can develop in the leg ?
A. Malignant leg ulcers include :
- a. Primary Skin Cancer : squamous cell carcinoma, melanoma
- b.
Marjolin's Ulcer : Squamous cell carcinoma in chronic ulcer,
osteomyelitis sinus or old scar. It is a slowly growing malignancy - c. Ulcerating Deep Cancer as osteosarcoma, fibrosarcoma of bone or muscle
A. This is very rare because of the severe fibrosis surrounding the ulcer
Oral Questions on a Case of Cleft Lip & Palate
Case 1. CLEFT LIP
Q. What is your diagnosis ?
A. Unilateral incomplete simple cleft lip not associated with cleft palate.
Q. What do you mean by incomplete ?
A. The cleft is not reaching the nostril floor.
Q. What do you mean by simple ?
A. There is no associated cleft of the alveolar margin.
Q. Did you hear about cleft lower lip ?
A. It is an extremely rare anomaly it is characterized by being median in position.
Q. What are the types of cleft palate you know ?
A.
Cleft uvula, cleft soft palate, incomplete cleft palate (Cleft soft
and hard palate not reaching the alveolar margin), Complete cleft
palate. Incomplete and complete cleft palate could be unilateral or
bilateral.
Q. What do you mean by uni or bilateral cleft palate ?
A. It depends on whether the mouth cavity is communicating with one or the two nasal cavities.
Q. When do you repair cleft lip ?
A. At about the age of 3 months.
Q. Why this age specifically ?
A.
It is preferred not to do the operation before this age because at
that age the Hb% is almost 10 gm% and the weight of the child is almost
10 bounds and this is optimum and safe for anasthesia (in other words,
the operation before this age is rather risky).
On
the other hand, the operation is preferred not to be delayed after
that age for the following reasons : 1) for the proper development of
teeth, 2) for psychological relief of the parents' worry about their
child and 3) for proper suckling (although the role played by the lip
in suckling is not that considerable if compared with that of the
palate).
Q. What is the principle of any operation described for the repair of cleft lip ?
A. The principles for any repair of cleft lip are :
1. To bypass the defect : by suturing the muscles, skin and mucous membrane (3 layer closure)
2. To lengthen the lip : by interpositioning of flaps from both sides adjusting all esthetic points.
Q. What is the commonest operation for the repair cleft lip ?
A. Millard repair.
Q. Why not to do freshening and direct suture without the need to do rotation and advancement flaps ?
A.
This direct suture would produce what is called "a lip notch" because
of the shortening of the lip at the edges of the cleft.
Q. What are the complications of cleft palate ?
A. 1) Malnutrition due to improper suckling.
2) Repeated chest infection due to aspiration from regurgitated food and water
3) Speech abnormalities
4) Otitis media due to Eustachean tube obstruction by oedema around its mouth.
Q. What is the cause of improper suckling in cleft palate ?
A. Failure to create an intraoral negative pressure.
Q. What are the speech abnormalities encountered in cleft palate ?
A. 1) Nasal tone of speech (Rhinolalia) and 2) Inability to pronounce some syllables like K, L, Q.
Q. At what age do you prefer to repair cleft palate ?
A.
The repair of the most anterior palate can be done during the same
operation of repair of the cleft lip, while the remaining posterior
palate is repaired at about the age of 11/2 to 2 years.
