Obs & Gynae End Posting Exam

As usual, MCQ, OBA and OSPE questions were easy peasy!! - only if you have read about the topics before sitting for exam lol how we wish we have a brain like sponge >..<

PMP 1 (Obs) was about Rhesus Isommunization and PMP 2 (Gynae) was on Ectopic Pregnancy with Pelvic Inflammatory Disease.

LONG CASE with Prof. Roszaman

42 year old Malay housewife, G4 P3 (last childbirth 7 years ago) at 37 weeks 5 days POG with underlying Gestational Diabetes Mellitus and late onset Pregnancy Induced Hypertension, admitted for Bishop score and Induction of Labour.

On examination, she was a medium build lady, alert and comfortable. She did not look pale or jaundiced. Abdomen looked distended with presence of gravid uterus. There was linea nigra and striae gravidarum seen, but no surgical scar or dilated veins. Abdomen soft and non-tender, uterus was not irritable. SFH 34 cm which was smaller than date. There was a singleton fetus lying in longitudinal lie cephalic presentation, fetal back at maternal right side. Fetal movement was felt on palpation. No contraction felt. Head 3/5th palpable. Estimated fetal weight 2.6-2.8kg. Liquor was adequate.

Prof interrupted in between my history, and asked a lot of questions. Some of them that I can remember:

1. Differences between complications of GDM and DM complicating pregnancy
2. How to screen for Down Syndrome antenatally? Ever heard of triple tests?
3. Side effects of methyldopa and labetolol
4. How to investigate IUGR?
5. List problems in this patient
6. Investigations you want to do
7. Management plan
8. Methods of induction of labour (medical and mechanical)

SHORT CASE with Prof. Mokhtar

17 year old big build Malay lady, lying in supine position, looked in pain. Branula attached at dorsum of right hand. She was not pale. Abdomen distended with presence of gravid uterus. There was linea nigra seen, but no surgical scar. Umbilicus was flat, abdomen looked tense.  Abdomen was tender at suprapubic area. SFH at 40 cm. There was a singleton fetus lying in longitudinal lie cephalic presentation, fetal back at maternal right side. I could not appreciate the head engagement. Estimated fetal weight was 2.8-3.0 kg. Liquour was excessive. Fluid thrill was positive.

1. What is latent phase of labour?
2. Definition of prolonged phase of labour
3. Complications that you expect for this patient during delivery - Prof wanted to hear the answer cord prolapse

Now let's focus on FINAL PRO EXAM!!

We were divided into 9 groups and there were 9 stations altogether, 20 minutes allocated for each station. I was in Group 6, with my other 13 friends. 

Here's a summary on what each station is all about.

STATION 6 
Lump and Bump - Dr. Yusuf

It's actually the cover of chest tube lol that was funny


STATION 8
X-Ray - Dr. Hisham

We did not have time to go through all xrays, basically we revised on how to read xrays.


Case 1

65 year-old gentleman with history of myocardial infarction 5 years ago, did angioplasty, on beta blocker and frusemide, presented with 5 days history of worsening dyspnea. Interpret his chest xray.

This is the chest xray of Mr.S, taken on (date) at (time), AP view (portable), right side is marked correctly. The patient is rotated, however it has good penetration and exposure. There is homogenous opacity over the right lung with blunting of costophrenic angle.

Diagnosis - Right pleural effusion

How to assess rotation, penetration and exposure?
1. Rotation : look at the distance between clavicle and spinous process (teardrop shape). It must be the same between right and left side.

2. Penetration : look at the last few lumbar vertebrae, near the heart, they must be visible

3. Exposure : can see first rib, diaphragm and lateral border of ribs. Anterior axillary line must intersect the middle of 6 1/2 anterior ribs.

How to manage this patient?
ABCDE first! Remember to do step by step, insert 2 large bore branula, take blood for investigations, CXR, ECG, and then chest tube insertion.

Case 2

65-year-old man, psychiatric patient, bed bound, presented with recurrence abdominal pain, abdominal distension and constipation. Interpret his abdominal xray.

Coffee bean sign!

Diagnosis - Sigmoid volvulus

Management?
ABCDE! Branula, hydration, consent for immediate sigmoidoscopy to derotate sigmoid. Then, put rectal tube. After that, can decide for rectopexy or sigmoid colectomy.

Complications of sigmoid volvulus?
Can cause bowel obstruction, ischaemia, perforation.

Case 3

Barium swallow : bird-beak appearance

Diagnosis? Achalasia!

Case 4

KUB XRay : Right staghorn calculi!

STATION 1
Abdomen - Mr. Mizam

Who wants to volunteer to examine this patient's abdomen?


Middle aged Chinese man comfortably lying in supine position. He looks pale but not jaundiced. On inspection of abdomen, there is no surgical scar seen, no dilated veins, visible pulsation or stigmata of chronic liver disease (spider naevi, gynaecomastia,  loss of axillary hair, caput medusae). There is no inguinal hernia. 


On palpation, there is a mass located at left iliac fossa measuring (? cm) that has well-defined margin, round in shape, can get above and can get below, smooth surface, firm in consistency, not mobile, tender on palpation, dullness on percussion (don't percuss if patient is in pain), not attached to skin or muscles. There is no hepatosplenomegaly, kidneys were not ballotable, no ascites.

Points to remember:

1. Stand at the end of patient's bed for general inspection
2. Look at patient's face when palpating abdomen or mass
3. Ask patient to flex his neck to check if mass is below or above muscle
4. Do skin pinch to check for attachment to skin

We didnt manage to discuss about the diagnosis, investigation and management because the time's up. Our friend says that it's a case of rectosigmoid carcinoma.




STATION 2
Thyroid - Prof. Junaini

Must master thyroid examination, confirm will come out in exam! At that time, there was no real thyroid patient, so one of us had to examine a normal male with no thyroid enlargement.


1. Ask patient to swallow water and protrude tongue

2. Do thyroid examination from back of patient
3. Check trachea and percuss retrosternal, check lymph nodes
4. Auscultate carotid bruit, check Pemberton sign
5. Check peripheral - fine tremor, sweating palms, pulse for atrial fibrillation, eyes for ophthalmopathy, shoulder for proximal myopathy

What do you know about thyroid carcinoma?

I made this myself, for future reference. Some of the information is from the internet.


STATION 3
Breast - Mr. Faiz

Practice, practice, practice! No patient with breast lump, so one of us had to wear fake boobs to be examined lol

Organise your examination:
1. Inspection - look for asymmetry, skin dimpling, peau de orange, discharge etc. 
2. Ask patient to raise both hands (look if there is anything underneath breast). Ask patient to press hands on hips (if there is attachment to pectoralis major, mass will become prominent).
3. Examine normal breast first, then the pathological one. Cover the other breast.
4. Ask patient to raise hand above head.
5. Lift up breast and look under breast for surgical scar (breast augmentation)
6. Palpate four quadrants + on nipple + below scapula
7. If there is a mass, describe it as usual - site, size, shape, surface etc.
8. Don't squeeze the nipple! Ask patient if she has any nipple discharge, if not then proceed. If yes, ask if she can demonstrate.
9. After examine both breasts, ask patient to sit down facing you. Check for axillary lymph nodes. Anterior, apical, medial, lateral and posterior. Check cervical and supraclavicular lymph nodes. Check spine tenderness (bone mets), percuss lung (pleural effusion, lung mets), auscultate lungs (reduced air entry, crepitations)
10. Ask patient to lie supine. Check for hepatomegaly.

STATION 4
Hernia - Mr. Islah

The patient was very willing to let us examine him, one person per group, that's a total of 9 students touching him....thank youu pakcik may Allah bless you!

Elderly man, lying comfortable in supine position. On inspection of abdomen, there is a midline laparotomy scar noted, with two transverse scars at right and left iliac fossa. There is an obvious right inguinal swelling, not extending to scrotum. There is no erythematous changes, no skin excoriation, no dilated veins, no punctum or discharge, no visible pulsation or peristalsis. Cough impulse is positive as the mass becomes obvious after coughing. 

On palpation, mass is oval in shape 5 x 4 cm, soft and doughy, has well-defined margin, non tender, not warm to touch, can get below and reducible. Occlusion test is negative. 

Genitalia examination is normal. Scrotum is well-developed. Both testis palpable, normal size. Normal spermatic cord, no bag of worms felt.

Since patient's swelling is completely reducible, I would like to ask patient to stand for further assessment. When patient standing, do transillumination test. It's negative.

I would like to complete my examination by doing per rectal examination, abdomen and respiratory examination.

How to do occlusion test?
Make sure swelling is completely reducible. Find landmark. Midway between ASIS and pubic tubercle (first bony prominence after pubic symphysis). Occlude opening with one finger. Ask patient to cough. If negative, ask patient to stand, finger still occlude the opening. Ask patient to cough again. 

Your complete provisional diagnosis?
Right recurrent completely reducible direct inguinal hernia with no complications such as strangulation, ischemia or incarceration.

How to know if its bowel or omentum?
- Bowel : Visible peristalsis on inspection, gurgling sensation on palpation and when you try to reduce it, initially it's hard and then becomes easy, bowel sound on auscultation

- Omentum : No visible peristalsis, soft and doughy on palpation and when you try to reduce it, it's easy initially but hard at last, no bowel sound heard

How to manage this patient?
Since this is a recurrent disease, I would like to take complete history and assess his risk factors (occupation, congenital, complications of previous operation, abdominal mass, urinary and bowel symptoms, respiratory problems, heavy lifting). After that, I would like to perform complete physical examination. Then, do pre-op assessment, optimize patient's condition, take blood for investigations, do CXR, ECG. Prepare patient for laparoscopic hernioplasty where we put in mesh to induce fibrosis and prevent hernia.

Advantages of laparoscopic surgery?
Small incision, less bleeding, less infection, faster recovery, reduced hospitalisation, reduced chronic pain

Disadvantages?
Need highly-experienced surgeon, longer operating time, risk of recurrence if surgeon is not experienced enough

Other options for surgery?
- Herniotomy : excision of sac after reduction, usually in children because they have weak and immature ligaments.
- Herniorraphy : reconstruction by using patient's own tissues

Type of open repair surgery that you know of?
- Lichtenstein : most common, flat mesh is placed on top of the defect
- Shouldice : four-layer reconstruction of fascia transversalis, difficult to perform
- Bassini : tension repair, edges of defect are sewn back together without any mesh 
- Desarda : simpler, faster, tension-free, mesh-free

Read more about Inguinal Hernia Surgery in this website.

Special types of hernia that you know of?
- Sliding hernia : an organ is part of hernia sac eg. colon or urinary bladder
- Pantaloon hernia (saddle bag hernia) : combined direct and indirect hernia
- Maydl's hernia : two adjacent loops of small intestine are within a hernial sac with a tight neck - double lumen.
- Richter's hernia : hernia involving only one sidewall of bowel
- Littre's hernia : hernia involving Meckel's diverticulum 

Read more about other types of hernia (there are a lot!) in this website.


STATION 5
Vascular - Mr. Ahmad Faidzal

The patient is a middle-aged Indian lady with varicose veins. We managed to feel defect in her veins. We did Doppler as well.

I have written about peripheral vascular examination last year, you can read it here. This is just a summary.

Remember : Inspection, Inspection, Inspection - Palpation, Percussion, Auscultation and Special Test.

Arterial system
1. Inspect for muscle wasting, colour, chronic signs of infection, arterial ulcer
2. Palpate for temperature, CRT, bone or joint tenderness, pulses (proximal to distal)
3. Ascultate bruit for AV malformation
4. Buerger's test - lift patient's leg and look at what angle it turns pale
5. Complete examination by doing ABSI, doppler, carotid pulse, cardiovascular, neurological and abdomen examination

What are the 6Ps of acute limb ischemia?
Pain, Pallor, Perishingly cold, Paralysis, Paraesthesia, Pulseless

Venous system
1. Inspect for calf swelling, lipodermatosclerosis, previous scar or healing ulcer, varicosity
2. Palpate the varicosity, tenderness (phlebitis), hardness (thrombosis), cough impulse
3. Auscultate bruit for AV malformation
4. Percussion is optional
5. Tradelenburg test and Multiple Tourniquet test
6. Complete examination by doing abdomen, per rectal, arterial system examination

Sooo... 10 stations COMPLETED!

Hope we can remember all of these points during exam!!

Hope all of us will pass the exam!! Amiiinnnn

Of the Results

Quick update.

1. Currently I am at the end of Week 3 in Obstetrics and Gynaecology posting. 3 more weeks to go, then one week of revision, and then exam week! Go Go!

2. I just realised that I havent posted my result in Internal Medicine yet.

It's sad to see how little mark I scored in MCQ =..=''

3. Last posting result - Paediatrics.

Slightly higher mark in MCQ. I think I didnt score a lot in PMP

4. Two sets of PMPs in end posting paediatric examination were about "Cardiogenic Shock secondary to Acute Rheumatic Fever / Rheumatic Heart Disease" and "Anaphylactic Shock secondary to Insect Bite".

For Long Case with Dr. Mohammad Nasser, I got a case of "Breakthrough Seizure" in a 10-year-old Malay girl. He listened to my presentation from history, physical examination, case summary, investigations and management. One of the questions asked was "What are the issues in this patient?". My patient's major issue was non-compliant to antiepileptic medications. She had been hospitalised frequently for the same complaint. Apart from that, she also had underlying bronchial asthma. I think, her parents being busy working all day might contribute to her compliance issue.

For Short Case, Dr. Chan gave me a case of "Nephrotic Syndrome". A boy with facial puffiness and bilateral pedal edema. She asked about differential diagnosis and investigations. 

You think Paediatrics is easy posting, but I doubt that. It's quite tough.

5. Preparing for SPA interview next week on 2nd June. All documents must be certified. Bring certificates. Read a bit on SPA and latest issues. 

Partial Academic Transcript

CFS Academic Transcript
C+ in Chemistry lol. I dont like neither Physics nor Chemistry.
Biology is cool.

6. If only you knew, what my heart goes through for you, I'm trying to break through, don't you think it's worth the chance? Let's leave the past, is that too much to ask?

And where do we stand? Can we pull through this avalanche?
