PMP END BLOCK QUESTION


Here is the recent end block PMP question that I prepared and marked recently. There are a lot of things that you can learn and also could be a "muhasabah" to me as well....... The answers and comments are right at the bottom.....
Trigger I

Mrs. G is a 45 year-old lady was referred by a physician when her series of blood investigations and endoscopic examination performed revealed normal findings. She frequently visited many doctors for many somatic symptoms such as body ache, epigastric burning sensation, non-specific headache and insomnia for the last 6 months. Occasionally she would feel that her heart was beating too fast when she thought of her physical symptoms. When her physician suggested her to meet a psychiatrist, she was initially skeptical as she did not feel that she had any psychiatric ailments.

1. Based on the short explanation above, list down 4 psychiatric differential diagnoses.

ANSWER
Q1 Answer:
Somatization disorder – top on the list
Major Depressive disorder with prominent somatic symptoms – good answer
Pain disorder
Hypochondriasis
Generalized anxiety disorder
Substance abuse/dependence- ½ mark (hardly they present with above symptoms)

Common mistakes done by students when they answer:
Somatoform disorder – wrong (non-specific)
Anxiety disorder - wrong (non-specific)
Factitious, Malingering disorder – wrong (should not think along this line first, not fair to your patient)
Q2 The answer is based on your diagnoses in question 1:
Any episode of persistent feeling depressed
Other depressive symptoms such as hopelessness, or melancholic features
For somatization disorder; other form of pain; sexual complaint, neurological symptoms (numbness)
Any drug abuse
Family history of similar symptoms or psychiatric disorder
Any recent stressor
Q3
Comment:
Many students failed to get the right answer although the presentation is very clear.
The correct answer is Major depressive disorder with prominent somatic symptoms.
Supporting evidences:
No other symptoms of somatization disorder
There are a lot of pessimistic ideas about her current and future life.
There is thought of dying.

Please bear in mind that among middle aged and elderly women in Asia, they tend to present with many somatic symptoms but in actual fact they are having major depression). Even the presentation of depression is commonly with somatic complaints.

Statistics on the result;
60% of students (12 students) answered major depressive disorder
15% (3) answered Adjustment Disorder (not accurate answer due to suicidal thought)
15% answered Somatization disorder (wrong it is clearly mentioned no other body complaint)
5% Conversion (0 mark – commonly conversion presents with neurological deficit e.g. paralysis)
5% (1 student) answered mixed anxiety and depressive symptoms (I’m speechless and no comment on the answer because it is not the diagnosis and the mark is definitely 0)
Common mistake made by students
Q4 Acceptable answers; Thyroid function test or cortisol

Q5 Answer:
Anhedonia
Early morning awakening (more than 2 hours from usual time)
Diurnal variation of mood (feeling depressed esp in early morning)
Excessive guilt
Psychomotor retardation/agitation

Common mistakes/wrong answers by students:
Feeling low mood every day, feeling low mood most of the time (this is a core symptom depression not melancholic feature)
Anorexia
Loss of emotional reactivity
Poor sleep
Q6 Answer
Bio-psychosocial spiritual model of management
Antidepressant SSRI
Psychoeducation
Family psychoeducation
CBT
Community or social welfare helps

Common mistake;
Students did not lay out the bio-psychosocial and spiritual model.
ECT is correct answer but if you mention ECT as the first choice, then it is wrong
Q7 Answer:
To develop therapeutic relationship and good rapport with the patient
Psychoeducation to the patient and family
Single dose antidepressant
Prescribe less side effect medicine.
Explanation on early relapse symptoms and possible side effects
Ensure good social support

Common mistakes:
When students answered depot injection (antidepressant has no depot form!!!!!!)
CBT or psychodynamic psychotherapy (they are targeting on cognitive errors not for insight enhancement!!!)
