Q

Hernias

A

•Direct inguinal
hernias arise from a weakness in the posterior wall of the inguinal canal,
allowing abdominal viscera to protrude ‘directly’ through the back of the
inguinal canal.
•In indirect inguinal hernias, the abdominal contents pass
through the deep inguinal ring and along the inguinal canal. The hernial
sacs in both conditions will protrude through the superficial ring and
produce a swelling in the groin. These two types of hernia are differentiated
on examination by reducing the hernia, placing a finger on the deep inguinal
ring and asking the patient to cough. As you are blocking the deep inguinal
ring with your finger, an indirect inguinal hernia should not reappear as a
groin lump when the patient is asked to cough. Therefore, if the hernia
appears again when the patient increases their intra-abdominal pressure (by
coughing), it suggests that it is a direct inguinal hernia. This test is very
crude and error prone — definitive diagnoses are often made in theatre.
•Spigelian hernias occur when
abdominal contents herniate through the linea semilunaris, typically
occurring inferior and lateral to the umbilicus.
•Obturator hernias occur
through the obturator canal and they present with inner thigh pain when the
hip is internally rotated (Howship–Romberg sign).

Q

Examination signs

A

○psoas sign — achieved by
lying the patient on their left-hand side, straightening their right leg and
then passively extending their right hip. If pain is elicited, this suggests that
the appendix is retrocaecal.

○Rovsing’s sign - when palpation of the left iliac fossa causes pain in the
right iliac fossa.

○Obturator sign - is pain on flexion and internal rotation of
the hip and indicates that the appendix lies close to the obturator internus.
○Aaron’s sign is referred as epigastric pain when pressure is applied over
McBurney’s point.
○ Murphy’s sign is the cessation of inspiration when two
fingers are placed below the right costal margin in the midclavicular line
and the patient is asked to take a deep breath in. This is suggestive of
cholecystitis.

○A keratoacanthoma is a variant of
SCC which grows rapidly but does not metastasise.
○Basal cell carcinomas -most common type of skin cancer. A skin lesion with
raised pearly edges and fine telangiectasia on the surface. It grows across
the skin but never metastasises.
○Melanoma - worst. an asymmetrical pigmented skin
lesion with an irregular border. rapid growth and metastasis

Q

Anaemias

A

○Haemolytic uraemic syndrome (HUS) is a triad of microangiopathic
haemolytic anaemia (MAHA), acute renal failure and thrombocytopaenia. It
most often occurs following a diarrhoeal infection by E. coli O157 in
children. N.B. The clotting screen is normal in HUS.
○ Thrombotic thrombocytopaenic purpura (TTP) has the same features as
HUS with the addition of fever and fluctuating neurological signs.
○ Disseminated intravascular coagulation (DIC) is widespread activation of
the clotting cascade resulting in low platelets, low Hb and low fibrinogen
with a high APTT/PT.

Q

Rectal masses

A

A
lump that protrudes with defecation and requires manual reduction suggests
haemorrhoids or rectal prolapse.
Grades of haemorrhoids:
Grade 1: no prolapse
Grade 2: prolapse on defecation but reduces spontaneously
Grade 3: prolapse requires manual reduction
Grade 4: remain persistently prolapsed and cannot be reduced

Type 1
rectal prolapse occurs when only the rectal mucosa protrudes through the
anus and type 2 occurs when all layers of the rectum protrude through the
anus, creating a mass which has palpable, concentric muscular rings.

way as viral pericarditis — pleuritic chest pain that is relieved by sitting
forward, fever and a pericardial rub.

Q

PVD

A

○ Intermittent claudication is a cramping pain in the lower
limb muscles that occurs on exercise and is relieved by rest.
○ Critical limb
ischaemia is a more severe form of PVD characterised by rest pain, night
pain and tissue loss (e.g. arterial ulcers, gangrene). This patient has all the
main features of critical limb ischaemia.
○ Leriche syndrome is a type of
intermittent claudication resulting in buttock claudication, erectile
dysfunction and weak distal pulses, due to aortoiliac stenosis.
○ PVD can be diagnosed using ABPI: 0.5–0.9 = peripheral vascular
disease; <0.5 = critical limb ischaemia.
○ Acute limb ischaemia is caused by sudden cessation of blood flow to a limb
by a thrombus or embolus (usually from AF). Chronic DVT causes leg
swelling, pain and skin discolouration.

systolic murmur and a double apex beat. family history
of sudden death

52
Q

infectious

mononucleosis (also known as glandular fever)

A

non-specific flu-like symptoms (fever, malaise, sore throat) along with
cervical lymphadenopathy and splenomegaly
Ampicillin and amoxicillin
should not be given to patients with suspected infectious mononucleosis
because it causes a widespread maculopapular rash in nearly all of these
patients.

53
Q

TB treatment

A

All four drugs are started at the same time
Rifampicin and Isoniazid — 6 months
Pyrazinamide and Ethambutol — 2 months
These drugs can be remembered using the mnemonic: RIPE
N.B. Pyridoxine (vitamin B6) is given alongside TB treatment because
isoniazid leads to vitamin B6 deficiency, which causes peripheral
neuropathy
