Over 400 medical students at Kings College London have had to re-sit an exam paper over claims of cheating with an app.
Complaints arose over claims that the lecturer who wrote the paper had based a lot of the questions on information in an app that they had also designed.
The BBC news website quoted that the author of the paper had an app on iTunes which “a few students” had been told about.
“Over 60% of the final paper was lifted from this app,” the student said.
“Instead of conducting a full investigation, Kings College London is making the whole year, 400 students, re-sit their exam only a few days after their practical exams, causing a lot of stress.”
Have you experienced similar issues? Do apps help or hinder your progress as a medical student?

We asked you about the treatment to this skin rash… and the answer is….
a. Coal Tar
This is the classic salmon pink rash of psoriasis. You can see the surface has a scaly appearance.
As the rash in psoriasis is palpable and spread over an area of >0.5cm it is called a plaque not a macule – (If it was an impalpable area of colour change it would be called a patch).
Skin psoriasis is treated by emmollients, vitamin D analogues, coal tars, dithranol, topical steroids and oral retinoids. Methotrexate and Anti TNF therapy in addition to other immune modulating therapies are used in severe cases. Remember the four main types:
- plaque (seen here)
- pustular (pustules often occuring on the hands and feet)
- guttate ( teardrop lesions -sometimes occuring following a streptococcal infection)
- erythrodermic (diffuse skin involvement – potentially lifethreatening)
Capsaicin is a Rubefacient: a topical skin irritant. Its use is based on the principle that irritation of the skin produces a “distracting” effect from the pain from OA/ neuropathy (e.g. post herpetic neuralgia).
It is used topically for osteoarthritis and neuropathic pain.
Capsaican is the “active” ingredient in chillies which gives them their heat. Its use over a rash like psoriasis would be liable to produce excruciating pain and significant inflammation.

We asked you about this 27 year old female who presented with a 3-day headache. After looking at her lumbar puncture results, the diagnosis is….
a. Benign Intracranial Hypertension
The pressure is very high! The CT was normal essentially excluding raised intracranial pressure secondary to an obstructive hydrocephalus (e.g. meningioma obstructing the 4th ventricle draining CSF). The red cells are high in the first sample of CSF but as further CSF is tapped off, this clears. This supports a slightly “traumatic” tap. Xanthochromia testing in the sample is negative, providing no evidence of a prior bleed into the CSF which has then been broken down into xanthochromia.
To diagnose a S.A.H. you have to have either blood or altered blood in the CSF. As a rule of thumb you should have “no” red cells in the CSF if its not a traumatic tap and there is no other pathological processes.
The diagnosis is BIH. This is reasonably common in young people and is not benign: untreated it can threaten sight. Treatment is via means to reduce CSF pressure e.g. repeated lumbar punctures.
