Clubbing


It's been some while since I last wrote. I have been busy with Neurology. Well, this patient is a 60 years old Malay man who was admitted to my ward with progressive L sided weakness over a week. He is non toxic looking and there is no stigmata of chronic liver disease. He has been a chronic smoker. To tell the truth, I was rather upset that 2 of my house officers could not come to a conclusion even after I mentioned the gross clubbing in this patient.
I hope medical students reading this will practice what has been learned in medical student years.
This is a clear cut case of Ca lung with metastasis to the brain.
What I would like to stress here is - Do not forget the causes of clubbing !

Respiratory :
Ca lung
Pulmonary fibrosis
Bronchiectasis
Chronic suppurative lung diseases
Cystic fibrosis

CVS :
Congenital cyanotic heart disease
Eisenmenger syndrome
Infective endocarditis

GI :
Chronic liver disease (Cirrhosis)
Inflammatory bowel disease

Thyrotoxicosis (pseudoclubbing - acropachy)

Plantar Response - Other than Babinski

art-sin447785.fig1.gif

Other than Babinski sign, what other signs do you know ?

In upper motor neuron lesion, the big toe will dorsiflex with the following :

Gordon reflex – On applying pressure to the muscle of the calf

Oppenheim sign – on applying heavy pressure with thumb and index finger to the shin, stroking downwords from below the knee down to the ankle

Bing reflex – when the dorsum of the toe is pricked with a pin

Schaefer reflex – pinching the Achilles tendon sufficiently to cause pain

Chadock reflex – on stroking the lateral side of the foot, beginning below the malleolus and extending anteriorly along the dorsum of the foot to the base of the big toe

Gonda reflex – grasping the small toes between the fingers, slowly and forcibly flexing the toe and then suddenly releasing the toe


I know an MRCP examiner who likes to ask this question. Try practicing it !  Physical examination is the most crucial step in Neurology.

MRCP PACES Course 2009

The time we feared most and the time we can't wait for it to be over. However, we choose to face it. PACES exam.....
We know that part of it is due to pure luck but if you are better prepared, the chances of passing is much higher.
Once again, Penang General Hospital, Seberang Jaya Hospital and Penang Medical College is planning for a MRCP PACES course the August 29 and 30. This is a soft launch for the course for those whom I am grateful for keeping up this blog. 

Thank you very much for the support. All entries are now closed. 

All the best !!

Tuberculous meningitis





A 45 year old man was admitted with a 3 day history of coma following 2 weeks of headache and fever. Examination revealed a GCS of 8/15, neck stiffness, and a complete R oculomotor nerve palsy. Examination of the CSF showed an opening pressure of 20 cmH2O, 800 leucocytes.mm3 (30% neutrophils, 70% lymphocytes), protein 180 mg/dl, CSF/ blood glucose 0.18. Gram and Ziehl-Neelsen stains of the CSF were negative. Culture of the CSF on Lowenstein Jensen media grew Mycobacterium tuberculosis.
(Adapted from Practical Neurology 2002)

This type of scenario can come out in the Part 1 or 2a MRCP and medical student exams. Not possible for PACES.

Name 3 complications of TB meningitis that may need neurosurgical intervention.
