    Clinical Examination Tutorial

1. Mrs. Smith has just separated from her husband, comes to see you with

    suspicion that her 2 year-old daughter might be sexually abused by her

    new partner. The child doesn‟t want to go back to her father‟s house. Task : Management

The main thing to do is doing nothing! Shouldn‟t contaminate the history by

    asking the child questions or do physical examination. These things need to be

    done by expert (Gatehouse Centre)

Ask general questions to the child, not sexual abused questions and do general

    PE, including find the evidence of possible child abused.

    - Would you like to stay with your dad? If not, why don‟t you like your dad?

Contact child protection or human service department.

I understand that it‟s very upsetting to you. This thing is beyond my

    responsibility, I‟d refer your child to Gatehouse centre. People there are expert in child sexual abuse, they will take sample from you child and find evidence to

    prove your suspicion. They will take care of your concern and I‟ll follow up you with the Gatehouse centre after everything is done.

Should I contact the police?

    Not necessary now, the Gatehouse centre will take care of that and if need to,

    they‟ll arrange for you.

If the child doesn‟t want to stay with her father and cannot isolate her from her

    step-father ? can admit the child for protection. Anyway, the first thing is refer

    to Gatehouse centre and they have their guideline for this.

    If it‟s a child abuse case, GP or HMO can do PE and record on the chart ? bruise, anal excoriation.

2. You are a local GP, 150 km from the nearest Paediatric Centre. The lady

    brings her daughter, 9, who has been diagnosed with DM type1 for 18

    months. You‟ve been asked to continue Mx for her. No further Hx. Task: Talk to the mother about your management

Management:

     a. Check BS record book

    b. Check HbA1C every 3 months

    c. Check the injection site

    d. Check blood pressure

    e. Check Urine sugar

     1

    f. Ensure follow up with endocrinologist, dietician and children diabetic clinic

    at least once a year

    g. Other issues:

    -Sick Mx

    -Exercise

    -Travel Mx

    -Eating ? don‟t skip meal

    -Review school report

Ask mum if she‟s coping alright

    Eye, heart and kidney complications: annual review from 10 or 12 years old

    3. Father of a 3 wk old child comes to you as child is vomiting profusely since

    last 2 days. No diarrhea. The father says „vomit went everywhere‟. The baby is

    on breast milk and feeds well. O/E: baby looks well, hydration good, v/s is

    given (all normal). Giant peristaltic waves seen on the abdomen. No mass felt.

    Task: Explain to the father what the problem is.

    No further history to be taken

If can ask questions: Questions to ask:

    - Is there any bile in vomitus?

    - How far is the vomiting?

    - Is the child febrile? ? meningitis, UTI

    - Gastro-esophageal reflux symptoms

    - Time of vomiting after feeding

Congenital pyloric stenosis

    ? 2-8 weeks after birth

    ? As stomach becomes bigger, the vomiting is more severe and more

    volume.

Complication of pyloric stenosis

    - Dehydration

    - Hypokalaemia

    - Alkalosis

I‟d like to do investigation to confirm my diagnosis.

    - U/S to see severity of the stenosis

    - U&E to see dehydration and electrolyte imbalance

Your child has a condition called “pyloric stenosis”, (draw a diagram) this part of

    the stomach has a thickened wall and slows down the food.

The treatment is a simple operation (pyloromyotomy) to make this site bigger

    and the successful rate is high. Your child will grow normally and everything

    will be normal. We need to refer your child to the surgeon as soon as possible.

     2

Does he have to have an operation now?

    The surgeon will assess his condition and decide whether he should have an operation now or later. The time of the operation depends on surgical team.

Treatment:

    ? Admit the child

    ? IV (might need NSS + KCl)

    ? Consult surgery

     4. Mr. Graham a 50 yr old man comes to ED, complaining of pain in his

    lumbar region for 3 days. He believes it may be spinal in origin. The

    pain became so severe 2 hours ago and was not settling. The nurse gave

    him some pain reliever and you are called to see him.

    Task: Take a history

     Tell the examiner what investigation you want to do.

     Explain the condition and management to the patient

    Pain occurred 3 times before for about 1 week. Father has stone but not sure where. His water work is smelly, thick color, no stone passing. He drinks occasionally and smokes 5-10/day for 20 years.

    Full ward test: Protein + RBC

    Microscopy:

    Blood U&E, Cr, uric acid normal

    Plain KUB: calcification 1 cm at lower 1/3 of the ureter with some

     Dilatation.

    U/S: Kidney size is normal, no stone, no dilated calyx.

Questions to ask:

    - Pain: site, size, radiation, relieved by, aggravated by, associated symptoms. - Any temperature

    - Trauma or lifting

    - 1st episode?

    - History of sciatica

    - Major health problem, any stone before, job sitting all the time

    - Fluid intake

    - PH, FH, Medication, Allergy, operation

Investigation:

    - 85% of stones are radio-opaque

    - Urine full ward test ? if +ve then MSU microscopy

    - Blood test is not really necessary

    - Plain KUB

    - Renal U/S to see kidney function, anatomy, size, dilatation - Abdomen CT scan if can‟t see stone from above tests

     3

DDX:

    ? Stone

    ? Sciatica

    ? Rib fracture

    ? Gallstones if right side

    ? Pyelonephritis if fever

We got the result of your test & found a stone there (draw a diagram), that‟s why

    you feel pain. This stone moves and irritates the ureter so there is RBC in the

    urine.

It‟s 1 cm, and too big to pass out by itself so I need to admit you and have either

    open surgery or laparoscopic surgery. I need to talk to the surgical urologist to

    consider taking it out.

It might be the previous stone that you had, fortunately, we found it early and

    kidney is not affected yet. To prevent further attacks, I suggest you to drink

    plenty of water.

Can I leave it there?

    If left there ? causes pain and affects your health and renal function: such as

    hydronephrosis.

If < 4 or 5 mm ? may pass, ask patient to pass urine using mesh to collect stone.

    If pass, plain KUB to see again.

Surgery:

    ? Endoscopy (cystoscopy with basket) if < 5 mm and < 5 cm from cysto-

    ureteric junction

    ? Shock wave lithotripsy

    ? Open surgery

    5. Magi, a 32 yr old woman, comes to see you complaining of feeling

    anxious and irritable 1 week before her period, resulting in her getting

    mood change from happy to miserable in a short time which leads to

    getting short tempered with work colleagues and family members.

    is regular and she had tubal ligation many years ago.

    ? OCP: No need in this case as she had tubal ligation. It‟s good for control of

    symptoms and contraception at the same time, SE > benefit for her.

    ? Mefenamic acid (Ponstan)

    ? If severe PMS and failed other methods ? can give anti-depressant (last
