Stevens-Johnson syndrome (SJS) & Toxic epidermal necrolysis (TEN):
• Drugs cause > 50% of SJS and up to 95% of TEN cases, but infection, vaccination, and graft-vs-host disease are also potential causes.
• Confirm the diagnosis by biopsy (showing necrotic epithelium) if clinical characteristics (eg, target lesions progressing to bullae, ocular and mucous membrane involvement, positive Nikolsky sign, desquamation in sheets) are inconclusive.
• Early treatment decreases the often high mortality rate.
• Except for mild cases, treat SJS/TEN in a burn unit and with intensive supportive care.
• Consult ophthalmology if the eyes are affected.
• Consider cyclosporine and possibly plasmapheresis for severe cases.

I think this is more likely to be EM than SJS, because Nikolsky sign is -ve, the lesions are raised (SJS lesions are macular), and the trunk is not affected.

If anyone has any other dx, plz tell me

Tile classification of pelvic fractures

Hand-foot-mouth disease (HFMD)

HFMD in an adult

Patients with unstable pelvic fractures are severely hemodynamically unstable. It is rare to see a stable pelvic fracture causing hemodynamic instability.

Therefore, if a patient has a stable fracture yet he is hemodynamically unstable, search for the cause elsewhere, such as the abdomen, the chest, or the lower limbs.

The mortality due to pelvic trauma is approximately 9%, yet it increases to 50% if the patient is hemodynamically unstable at presentation.

Cerebral palsy (CP)

It's an umbrella term for the neurodevelopmental disorders that cause motor problems. Most of the cases have their etiology prenatally (rarely postnatally), and are caused by things like infections, hypoxia, and head trauma. They are only rarely due to genetic mutations.

It is classified according to its effect on the motor system:
• Spastic (pyramidal), due to lesions in the upper motor neurons of the pyramidal system. It has many subtypes, like spastic hemiplegic, and diplegic CP.
• Dyskinetic (extrapyramidal), due to lesions in the basal ganglia leading to symptoms such as chorea and dyskinesia.
• Ataxic, due to cerebellar problems.

You should be able to differentiate between ecchymosis, purpura, and hematoma.
