| Steven’s Johnson’s Syndrome | SJS, often referred to as a more severe version of erythema multiforme, is a hypersensitivity reaction that occurs in response to various triggers, including infections, medications, and malignancy. Infectious agents include viruses, bacteria, fungi, and protozoa. Many medications, such as NSAIDs, antiepileptics, penicillins, sulfa drugs, TNF-alpha antagonists, and some antidepressants, have also been implicated. More than a quarter of cases may be idiopathic. |
| Toxic Epidermal Necrolysis | SJS may involve the mucous membranes, including the eyes and gastrointestinal tract. When more than 30% of the body surface area is involved, cases are generally referred to as toxic epidermal necrolysis. Treatment is symptomatic, including treatment of superinfection and pain control. Patients with severe cases should immediately be fluid-resuscitated and treated as burn victims. Offending agents should be removed or treated. Use of steroids is controversial. Involvement of specialists, including ophthalmologists, immunologists, and burn specialists, may be indicated. Morbidity and mortality are correlated with the percentage of body surface area involved. |
| Henoch-Schonlein purpura (HSP). | |
| Idiopathic thrombocytopenic purpura (ITP) | Platelet count is generally normal in HSP, helping to differentiate it from idiopathic thrombocytopenic purpura (ITP), which has low platelets. ITP presents with petechiae, bruising or bleeding, often in areas of trauma. If counts are sufficiently low, there is a risk for intracranial bleed. A consult with hematology can help determine appropriate management in case of uncertainty. |
| Rocky Mountain Spotted Fever | RMSF is the most common fatal tick-borne disease in the United States. It is caused by Rickettsia rickettsii. Multiple ticks may serve as vectors, including the American dog tick, the common brown dog tick, and the Rocky Mountain wood tick. The incidence is highest in individuals aged 5-9 and 60-69 years. The majority of cases occur between April and September in the Southeast and Midwest United States. A tick must feed for 6 hours before infection transmission occurs, and Rickettsia replicate for an average of 1 week before clinical symptoms begin. The most common symptoms are high fever (> 102° F), headache, rash, and myalgias. Image courtesy of the US Centers for Disease Control and Prevention. |
| Allergies | Pollen: Trees pollinate from late winter to spring Grasses pollinate during late spring and summer. Weeds pollinate during the late summer and fall.Mold: Most molds, whose habitats include rotting logs and fallen leaves, do not follow a clear seasonal pattern for allergen dispersal. They are primarily dependent on weather patterns to release their spores, with some needing dry, breezy weather and others requiring high humidity and the resulting fog or dew. |
