What term is used to describe this finding? Q:
1. Hyphema
Layering of blood in the anterior segment is termed hyphema. Hypopyon refers to pus in the anterior segment. Iridocyclitis refers to inflammation of the iris. Iridodonesis is a quivering of the iris when the patient moves the eye. Synechia is an adhesion between the iris and the lens.

What is the diagnosis? Q:
5. Keratoderma blennorrhagicum
These vesiculopustular waxy lesions are most consistent with keratoderma blennorrhagicum. This finding should prompt diagnostic testing for sexually transmitted or gastrointestinal pathogens.

Treatment with which one of the following medications is associated with this clinical finding?
Q:
1. Erlotinib
Erlotinib, a tyrosine kinase inhibitor of the epidermal growth factor receptor, induces characteristic hair alterations. Trichomegaly, curling, elongation, and trichorrhexis are typical; these reverse after discontinuation of therapy. The pictured changes are not typical of leflunomide, methotrexate, pegvisomant, or psoralen.

Serotonin SyndromeSerotonin Syndrome
• Described in all age groups.
• In 2004, the Toxic Exposure Surveillance System identified 48,204 exposures to SSRI that resulted in mod-major outcomes in 8187 patients and death in 103 patients.
• Diagnosed based on clinical findings; Hunter Diagnostic Toxicity Criteria Rules.
MechanismMechanism• Due to excess of serotonergic activity at CNS and
peripheral serotonin receptors. – Produce autonomic, cognitive and somatic effects.
• Drugs that may contribute:– Anti-depressants (SSRIs, MAOIs, SNRIs, trazodone )– Opiods (tramadol, fentanyl, oxycodone )– CNS stimulants (cocaine, methylphenidate)– 5-HT agonists (triptans)– Psychedellics (LSD, MDA)– Herbs (St. Johns Wort, ginseng, nutmeg)– Others including:tryptophan, L-dopa, valproate, lithium
linezolid, ondesetron, metoclopramide, dextromethorphan
(AND MORE!)
Hunter CriteriaHunter Criteria• Must have taken a serotonergic agent and
1+ of the following:– Spontaneous clonus– Indicible clonus + agitation or diaphoresis– Ocular clonus + agitation or diaphoresis– Tremor and hyperreflexia– Hypertonia– Temp >38C + ocular clonus or inducible clonus*Findings often more pronounced in LE.
TreatmentTreatment• Discontinue serotonergic agent. • Sedate using benzodiazepines. • Supportive cares: oxygen, IV fluids, cardiac
monitoring. • Anticipate complications, VS can fluctuate
widely. • If benzos and supportive cares not adequate, may
need to use cyproheptadine. • Treat temperatures >41C with standard measures
including intubation and sedation but try to avoid APAP.
PrognosisPrognosis
• Good! (Unlike an attack by a slap bracelet )
– Patients usually respond within 24 hours.
However, the difficulty can be a co-ingestion as this is often seen with serotonin syndrome.
