Q

50-year-old man with a history of ulcerative colitis comes for review. Six years ago he had an
ileostomy formed which has been functioning well until now. Unfortunately he is currently suffering
significant pain around the stoma site. On examination a deep erythematous ulcer is noted with a
ragged edge. The surrounding skin is erythematous and swollen. What is the most likely diagnosis?
Munchausen’s syndrome
Irritant contact dermatitis
Pyoderma gangrenosum
Dermatitis artefacta
Stomal granuloma

A

Pyoderma gangrenosum is associated with inflammatory bowel disease and may be seen around the
stoma site. Treatment is usually with immunosuppressants as surgery may worsen the problem
A differential diagnosis would be malignancy and hence lesions should be referred for specialist
opinion to evaluate the need for a biopsy. Irritant contact dermatitis is common but would not be
expected to cause such a deep ulcer.

Q

You are asked to review a 60-year-old Greek man with known glucose-6-phosphate dehydrogenase
(G6PD) deficiency who was admitted with malaria and a chest infection. He has developed jaundice
and haemolytic anaemia after starting some medications this morning.
Which of these medications are most likely to have precipitated his crisis?
Clarithromycin
Amoxicillin
Artesunate
Primaquine
Salbutamol
.

A

Primaquine
is a well known cause of haemolysis in G6PD deficiency and is used in the treatment of
malaria. Artesunate is generally considered safe to use in G6PD deficiency. Penicillins and macrolides
are safe antibiotics to use in G6PD deficiency.

Q

42-year-old woman presented with sudden onset gait ataxia, intention tremor and nystagmus. CT
head demonstrated a 4cm left cerebellar haematoma. She is discussed with the local neurosurgical unit
and urgently transferred for intervention. She is repatriated a week later for further rehabilitation.
Routine blood tests are notable for a platelet count of 1,700 * 109
/l . Initially, you attribute this to a
post-surgical rise. However, on closer examination of her results you realise that on initial presentation
her platelet count was 1,300 * 109
/l. What gene mutation is likely to be discovered in this lady?
JAK2
HFE
CFTR
WASP
BCR-ABL

A

JAK2
This lady has presented with a stroke at a young age, on a background of raised platelets. This is very
suggestive of essential thrombocythaemia which is known to be a rare cause of stroke and is
associated with a mutation in the JAK2 gene.
HFE mutation is seen in haemochromatosis, CFTR in cystic fibrosis and WASP in Wiskott-Aldrich.
Mutations in BCR-ABL are associated with chronic myeloid leukaemia, and is known as the
Philadelphia translocation.

A

Aplastic crisis
The sudden fall in haemoglobin without an appropriate reticulocytosis (3% is just above the normal
range) is typical of an aplastic crisis, usually secondary to parvovirus infection

Q

A 34-year-old man who is HIV positive is starting treatment for Burkitt’s lymphoma. His
chemotherapy regime includes cyclophosphamide, vincristine, methotrexate and prednisolone. Around
24 hours after starting chemotherapy he becomes confused and complains of muscle cramps in his

Burkitt's lymphoma is an uncommon, very high grade non Hodgkin's lymphoma endemic to west Africa and the mosquito belt. There is a close association with contraction of Epstein Barr virus (EBV). Burkitt's lymphoma often presents with symmetrical painless lymphadenopathy, systemic B symptoms (fever, sweats and weight loss), central nervous system involvement and bone marrow infiltration. Classically in the textbooks the patient also develops a large jaw tumour.

72-year-old man is admitted with a deep vein thrombosis. He is normally fit and well but has recently lost weight.

65-year-old woman is reviewed. She is on the waiting list for a varicose vein operation but during the preoperative assessment was noted to have a raised lymphocyte count. She reports feeling well currently and clinical examination is normal. Her bloods were as follows: Hb 11.8 g/dl Plt 184 * 109 /l WBC 21.2 * 109 /l There are no previous bloods to compare these results with. Following referral to haematology a diagnosis of chronic lymphocytic leukaemia was made. What is the most appropriate management?

``` A 73-year-old woman is reviewed in the pre-op clinic prior to an elective hip replacement. Her past medical history includes polymyalgia rheumatica and ischaemic heart disease.
