A 74-year-old man presents to the physician with complaints of hoarseness of voice and cough for the past 3 weeks. The patient has been a smoker and quit 3 years ago. Radiological examination reveals a mass in the mediastinum. Which investigation should be employed to establish a diagnosis?
Your Answer: CT thorax
Correct Answer: LN biopsy
Explanation:Masses in the middle mediastinum most commonly represent lymph nodes that are enlarged by a malignant, infectious, or inflammatory process. Masses in the posterior mediastinum are usually benign tumours or cysts originating from either the nerves that are present in this area (neurogenic tumours) or from the oesophagus (foregut duplication cysts). Lymph node biopsy would be the ideal choice of investigation in this case.

A 75-year-old woman presented with difficulty in climbing the stairs and difficulty in holding her head up, for the past 6 months. She didn't have any significant joint pain. Her creatinine phosphokinase level was very high and ESR was normal. Which of the following is the most probable diagnosis?
Your Answer: Polymyalgia rheumatica
Correct Answer: Polymyositis
Explanation:Polymyositis is an idiopathic inflammatory myopathy characterized by symmetrical, proximal muscle weakness, elevated skeletal muscle enzyme levels and characteristic electromyography (EMG) and muscle biopsy findings. Weak neck extensors cause difficulty holding the head up. Pain is not a significant symptom, which differentiates it from arthritic conditions. ESR is elevated in only 50% of patients with polymyositis.

A 20-year-old heroin addict is admitted following an overdose. She is drowsy and has a respiratory rate of 6 bpm. Which of the following arterial blood gas results (taken on room air) are most consistent with this?
Your Answer: pH = 7.31; pCO2 = 7.4 kPa; pO2 = 8.1 kPa
Explanation:In mild-to-moderate heroin overdoses, arterial blood gas (ABG) analysis reveals respiratory acidosis. In more severe overdoses, tissue hypoxia is common, leading to mixed respiratory and metabolic acidosis.
The normal range for PaCO2 is 35-45 mmHg (4.67 to 5.99 kPa). Respiratory acidosis can be acute or chronic. In acute respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range (i.e., >45 mm Hg) with an accompanying academia (i.e., pH < 7.35). In chronic respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range, with a normal or near-normal pH secondary to renal compensation and an elevated serum bicarbonate levels (i.e., >30 mEq/L).
Arterial blood gases with pH = 7.31; pCO2 = 7.4 kPa; pO2 = 8.1 kPa would indicate respiratory acidosis.

An 8-year-old boy was admitted following a MVA. His BMI is 28 kb/m2 and he's been found to have glycosuria, which resolved after his recovery. Which investigation is necessary to perform as part of the follow-up?
Your Answer: Glycosylated haemoglobin (HbA1c)
Correct Answer: Fasting blood glucose concentration
Explanation:The boy has an increased BMI which implies he is overweight. Possible trauma to his pancreas might have led to a diabetes-like condition, induced by damage to the beta cells. Fasting blood glucose should be measured as a follow-up strategy to see if the damage is reversible or irreversible and to conclude if the glycosuria is related to his metabolic profile or to his accident.

A diagnosis of ulcerative colitis is suspected. Which part of the bowel is most likely to be affected?Your Answer: Terminal ileum
Correct Answer: Rectum
Explanation:The most COMMON site of inflammation from ulcerative colitis is the rectum, making this the correct answer. This is simply a fact you need to memorize. In general, ulcerative colitis only occurs in colorectal regions– nothing in the small bowel (unless there is backwash into the terminal ileum) and nothing further up the GI tract. In Crohn’s it can affect the entire GI tract from mouth to anus.

A 22-year-old male has had complex tics since childhood. He repeatedly bends his knees and rubs his nose. He is prone to loud vocalisations, sometimes including swear-words. A diagnosis of Gilles de la Tourette syndrome has been made. Which of the following is the best treatment option?
Your Answer: Cognitive-behavioural therapy
Correct Answer: Risperidone
Explanation:Gilles de la Tourette syndrome is the most severe and rare of the tic syndromes, consisting of multiple tics involving both motor actions and vocalisation. Onset is usually in childhood. Symptoms include utterance of obscenities (coprolalia); echolalia (repetition of another person’s spoken words) and palilalia (involuntary repetition of words, phrases, or sentences).
The underlying cause is unknown, with no particular imaging or standard histopathological abnormalities having been identified. The EEG shows non-specific abnormalities in about half of patients. However, more recent immunocytochemical studies have suggested altered dopamine uptake in the striatal system.
Risperidone is an effective therapeutic option without the effects associated with chlorpromazine and haloperidol. -

A 37-year old female nurse presents with severe generalized itching, claiming that she had previously applied cream to the body of a patient with similar symptoms. What is the mechanism that produces her itch?
Your Answer: None of the above
Correct Answer: Allergic reaction
Explanation:Contact dermatitis is a red, itchy rash caused by direct contact with a substance or an allergic reaction to it. The entry of allergen into the epidermis or dermis causes a localized allergic reaction. Local mast-cell activation in the skin leads immediately to a local increase in vascular permeability, which causes extravasation of fluid and swelling. Histamine released by mast cells activated by allergen in the skin causes large, itchy, red swellings of the skin.

A 23-year-old woman presents with lethargy. Her bloods show: Hb: 10.4 g/dL Plts: 278 x 10^9/L WCC: 6.3 x 10^9/L MCV: 68 fL Blood film: Microcytic hypochromic RBCs, marked anisocytosis and basophilic stippling noted HbA2: 3.9% What is the most likely diagnosis?
Your Answer: Hereditary spherocytosis
Correct Answer: Beta-thalassaemia trait
Explanation:Individuals with thalassemia major usually develop symptoms within the first two years of life. These infants may fail to thrive and often have difficulty feeding, tire easily and suffer from severe anemia.
The infants may also suffer from diarrhea, irritability, recurrent episodes of fever, and other intestinal problems. These children have trouble gaining weight and growing at the rate expected for their age. Other complications include enlarged spleen, heart and liver and misshapen bones.
In many cases, the symptoms are severe enough to warrant regular blood transfusion to replenish the blood with healthy red blood cells. However, these regular transfusions can lead to a build up of iron in the blood that can damage the heart, liver and endocrine system and chelation therapy may be needed to remove this iron from the body.
Individuals with beta thalassemia trait usually have evidence of microcytosis and increased levels of hemoglobin A2. Hemoglobin F is sometimes elevated as well. Individuals with alpha thalassemia trait usually have evidence of microcytosis and normal levels of hemoglobin A2 and F.
In thalassemia major, the hemoglobin (Hb) level is usually less than 7 g/dl; the mean corpuscolar volume (MCV) less than 70 fl and the mean corpuscolar Hb (MCH) is over 20 pg.
In thalassemia intermedia, the hemoglobin level is between 7 and 10 g/dl; the MCV between 50 and 80 fl and MCH between 16 and 24 pg.
Thalassemia minor is characterized by a reduced MCV and MCH and an increased haemoglobin A2 level.

A 17-year-old Jewish girl presents with primary amenorrhoea. On examination, she looks a little hirsute and has evidence of facial acne. She is within her predicted adult height and has normal breast and external genitalia development, however, there is excess hair over her lower abdomen and around her nipple area.
Investigations were as follows:
Hb 13.1 g/dl
WCC 8.6 x109/l
PLT 201 x109/l
Na+ 139 mmol/l
K+ 4.5 mmol/l
Creatinine 110 µmol/l
17-OH progesterone 1.4 times the upper limit of normal
Pelvic ultrasound: bilateral ovaries and uterus visualised.
Which of the following is the most likely diagnosis?Your Answer: Polycystic ovarian syndrome
Correct Answer: Non-classical congenital adrenal hyperplasia
Explanation:Mild deficiencies of 21-hydroxylase or 3-beta-hydroxysteroid dehydrogenase activity may present in adolescence or adulthood with oligomenorrhea, hirsutism, and/or infertility. This is termed nonclassical adrenal hyperplasia.
Late-onset or nonclassical congenital adrenal hyperplasia (NCAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive disorders. Reported prevalence ranges from 1 in 30 to 1 in 1000. Affected individuals typically present due to signs and symptoms of androgen excess.
Treatment needs to be directed toward the symptoms. Goals of treatment include normal linear growth velocity, a normal rate of skeletal maturation, ‘on-time’ puberty, regular menstrual cycles, prevention of or limited progression of hirsutism and acne, and fertility. Treatment needs to be individualized and should not be initiated merely to decrease abnormally elevated hormone concentrations.

A 15-year-old child with learning difficulties is referred to the endocrine clinic for review. His lab results show hypocalcemia and increased serum concentration of parathyroid hormone. On examination, there is subcutaneous calcification and a short fifth metacarpal in each hand.
What is the treatment of choice in this case?Your Answer: Calcium supplementation
Correct Answer: Calcium and vitamin D supplementation
Explanation:This child has pseudo hypoparathyroidism. It is a heterogeneous group of rare endocrine disorders characterized by normal renal function and resistance to the action of parathyroid hormone (PTH), manifesting with hypocalcaemia, hyperphosphatemia, and increased serum concentration of PTH.
Patients with pseudo hypoparathyroidism type 1a present with a characteristic phenotype collectively called Albright hereditary osteodystrophy (AHO). The constellation of findings includes the following:
Short stature
Stocky habitus
Obesity
Developmental delay
Round face
Dental hypoplasia
Brachymetacarpals
Brachymetatarsals
Soft tissue calcification/ossification
The goals of therapy are to maintain serum total and ionized calcium levels within the reference range to avoid hypercalcaemia and to suppress PTH levels to normal. This is important because elevated PTH levels in patients with PHP can cause increased bone remodelling and lead to hyper-parathyroid bone disease.
The goals of pharmacotherapy are to correct calcium deficiency, to prevent complications, and to reduce morbidity. Intravenous calcium is the initial treatment for all patients with severe symptomatic hypocalcaemia. Administration of oral calcium and 1alpha-hydroxylated vitamin D metabolites, such as calcitriol, remains the mainstay of treatment and should be initiated in every patient with a diagnosis of pseudo hypoparathyroidism. -

A 53 year-old dancer presents to the ED with increasing weakness. She has no pertinent past medical history aside from a recent diarrhoeal illness, which she attributes to an undercooked chicken meal. Her husband says that she has been unable to get up out of a chair for the past day. Upon examination, there is bilateral limb weakness and areflexia noted, but it is more severe in the lower limbs. You notice that if she lies flat in the bed, her oxygen saturations fall by around 2% on the pulse oximeter and she is unable to perform spirometry. Which of the following represents the most appropriate immediate management of choice in this patient?
Your Answer: High dose iv corticosteroids
Correct Answer: ITU review for consideration of ventilation
Explanation:This woman has a history that is suggestive of Guillain- Barre syndrome. This may be precipitated by Campylobacter, and her history of recent diarrhoeal illness is pointing towards that. Certain features point to a poor prognosis, including rapidity of onset, reduced vital capacity or respiratory failure, age >40 and reduced amplitude of compound muscle action potential. Her inability to perform spirometry and desaturating whilst lying flat are suggestive of impending respiratory muscle weakness. Review for consideration of ventilation is recommended. Further management of choice for Guillain-Barre syndrome is IV immunoglobulins. Steroids have no value in the treatment of the condition.

An 80-year-old woman is brought to the ER with altered sensorium. She is accompanied by her daughter who noticed the acute change. The patient has had a nagging cough with purulent sputum and haemoptysis for the last few days. Previous history includes a visit to her GP two weeks back because of influenza.
On examination, the patient appears markedly agitated with a respiratory rate of 35/min. Blood gases reveal that she is hypoxic. White blood cell count is 20 x 109/l, and creatinine is 250 mmol/l. Chest X-ray is notable for patchy areas of consolidation, necrosis and empyema formation.
Which of the following lead to the patient's condition?Your Answer: Mycoplasma pneumonia
Correct Answer: Staphylococcus aureus pneumonia
Explanation:Though a common community pathogen, Staphylococcus Aureas is found twice as frequently in pneumonias in hospitalized patients. It often attacks the elderly and patients with CF and arises as a co-infection with influenza viral pneumonia. The clinical course is characterized by high fevers, chills, a cough with purulent bloody sputum, and rapidly progressing dyspnoea. The gross pathology commonly reveals an acute bronchopneumonia pattern that may evolve into a necrotizing cavity with congested lungs and airways that contain a bloody fluid and thick mucoid secretions.

A 21-year-old university student is taken to the A&E. She lives alone in a small apartment. She is normally fit and well but she has been complaining of difficulty concentrating in classes. She is a one pack per day smoker and she has no significant past medical history. She is also not on any medication.
She had a pulse of 123 beats per minute and her blood pressure was measured to be 182/101 mmHg. She looked flushed. Chest x-ray was normal and her oxygen saturations were normal. She has typical features of carbon monoxide poisoning.
Initial investigations showed:
Haemoglobin 13.0 g/dL (11.5-16.5)
White cell count 10.3 x109/L (4-11 x109)
Platelets 281 x109/L (150-400 x109)
Serum sodium 133 mmol/L (137-144)
Serum potassium 3.7 mmol/L (3.5-4.9)
Serum urea 7.3 mmol/L (2.5-7.5)
Serum creatinine 83 μmol/L (60-110)
Drug screen Negative
Arterial blood gases on air:
pO2 7.9 kPa (11.3-12.6)
pCO2 4.7 kPa (4.7-6.0)
pH 7.43 (7.36-7.44)
Which test would confirm this diagnosis?Your Answer: Carboxy haemoglobin
Explanation:Carbon monoxide (CO) is a colourless, odourless gas produced by incomplete combustion of carbonaceous material. Clinical presentation in patients with CO poisoning ranges from headache and dizziness to coma and death. Hyperbaric oxygen therapy can significantly reduce the morbidity of CO poisoning, but a portion of survivors still suffer significant long-term neurologic and affective sequelae.
Complaints:
Malaise, flulike symptoms, fatigue
Dyspnoea on exertion
Chest pain, palpitations
Lethargy
Confusion
Depression
Impulsiveness
Distractibility
Hallucination, confabulation
Agitation
Nausea, vomiting, diarrhoea
Abdominal pain
Headache, drowsiness
Dizziness, weakness, confusion
Visual disturbance, syncope, seizure
Faecal and urinary incontinence
Memory and gait disturbances
Bizarre neurologic symptoms, comaVital signs may include the following:
Tachycardia
Hypertension or hypotension
Hyperthermia
Marked tachypnoea (rare; severe intoxication often associated with mild or no tachypnoea)
Although so-called cherry-red skin has traditionally been considered a sign of CO poisoning, it is in fact rare.The clinical diagnosis of acute carbon monoxide (CO) poisoning should be confirmed by demonstrating an elevated level of carboxyhaemoglobin (HbCO). Either arterial or venous blood can be used for testing. Analysis of HbCO requires direct spectrophotometric measurement in specific blood gas analysers. Elevated CO levels of at least 3-4% in non-smokers and at least 10% in smokers are significant.

What are the most common types of transformation seen in patients with polycythaemia vera?
Your Answer: Myelodysplasia + acute myeloid leukaemia
Correct Answer: Myelofibrosis + acute myeloid leukaemia
Explanation:5-15% of the cases of polycythaemia vera progress to myelofibrosis or acute myeloid leukaemia (AML).
Polycythaemia vera (PV), also known as polycythaemia rubra vera, is a myeloproliferative disorder caused by clonal proliferation of marrow stem cells leading to an increase in red cell volume, often accompanied by overproduction of neutrophils and platelets. It has peak incidence in the sixth decade of life, with typical features including hyperviscosity, pruritus, splenomegaly, haemorrhage (secondary to abnormal platelet function), and plethoric appearance.
Some management options of PV include lose-dose aspirin, venesection (first-line treatment), hydroxyurea (slightly increased risk of secondary leukaemia), and radioactive phosphorus (P-32) therapy.
In PV, thrombotic events are a significant cause of morbidity and mortality. 5-15% of the cases progress to myelofibrosis or AML. The risk of having AML is increased with chemotherapy treatment.

A 17-year-old boy presents with a 2 day history of colicky abdominal pain, vomiting and diarrhoea. He has been passing blood mixed with diarrhoea. He has no significant past medical history and takes no regular medication.
On examination he is pyrexial and clinically dehydrated. Cardiorespiratory and abdominal examinations are normal.
What is the most likely diagnosis?Your Answer: Campylobacter infection
Explanation:The patient has bloody diarrhoea that sounds like a food poisoning in the clinical scenario. Campylobacter is the most common cause of this in the United Kingdom. This is then followed by Salmonella and Shigella. The symptoms are usually self limiting. This is more likely to be bacterial from the food than a viral gastroenteritis.

ECG - Lateral ST depression , Upper GI endoscopy reveals a large bleeding ulcer on the posterior aspect of the duodenum. It cannot be easily reached with the endoscope, and you decide to attempt embolization.
Which of the following is the artery that should be targeted?Your Answer: Gastroduodenal artery
Correct Answer: Posterior Superior Pancreaticoduodenal artery
Explanation:The most common location for a duodenal ulcer bleed is the posterior duodenum (remember: posterior bleeds, anterior perforates). The perfusion to this area is most specifically from the posterior superior pancreaticoduodenal artery.
The anterior superior pancreaticoduodenal artery supplies the anterior region. The gastroepiploic artery supplies mostly the stomach. The splenic artery goes, obviously, toward the spleen, in the other direction. The gastroduodenal artery is a branch of the celiac artery, and it’s branches are the anterior superior pancreaticoduodenal artery and posterior superior pancreaticoduodenal artery.
