Diagnosis

Shown below are 04 algorithms summarizing the diagnosis of Rash with fever in a patient:

Patient with Fever and Rash

Take complete history

Record Vital signs: ❑ Measure the temperature ❑Record Pulse rate ❑Record Blood pressure ❑Record Respiratory rate

Ask about associated symptoms: ❑ Vomiting ❑ Nausea ❑ Abdominal Pain ❑ Cough ❑ Sore throat ❑ Chest pain ❑Arthralgias

Ask about other medical history: ❑ Asplenia ❑ Infection or Inflammation ❑Sarcoid ❑ Malignancy ❑ Collagen vascular disease ❑Any recent medications ❑Valvular heart disease ❑Chronic liver disease ❑Solid organ or bone marrow transplantation ❑Steroid use ❑Chemotherapy related immune suppression

Ask about recent Exposure: ❑Communal living ❑ Tick exposure ❑ Dog exposure ❑ Salt water exposure ❑ Tampon use ❑ IVDU ❑Trauma and Diabetes Mellitus ❑Exposure to sexually transmitted disease, including risk factors for infection with human immunodeficiency virus (HIV)

Ask about recent travel history: ❑ International Travel history ❑Travel in the mid-Atlantic, central, western, and northeastern parts of the United States(Lyme disease is common) ❑Travel in wooded areas(Rocky Mountain spotted fever and tick-borne diseases are common) ❑ Recent camping fever (RMSF) and other tick-borne illnesses.

General Physical Examination: ❑General appearance-Is the patient toxic? or normal appearance ❑Look for new-onset heart murmur or nuchal rigidity ❑Nuchal rigidity. ❑Palpate Lymph nodes for Generalized lymphadenopathy ❑Conjunctival injection ❑Look for Nikolsky sign:Sloughing of full-thickness skin with lateral pressure ❑Look for any lesion on the back, buttocks, or perineum ❑ In diabetic patients check feet ❑Palpate abdomen for hepatosplenomegaly

Characterize rash

Maculopapular rash

Petechial/Purpuric rash

Vesiculobullous rash

Erythematous rash

Terminolgies used to diagnose Rashes

Term	Clinical Features
Lesion	Single,Small affected area
Rash	An eruption on the skin; more extensive than a single lesion
Macule	Well circumscribed area of change without elevation
Papule	Solid raised lesion ≤1 cm
Petechia	Small red/brown macule ≤1 cm that does not blanche
Purpura	Hemorrhagic area > 3 mm that does not blanch

If a patient present with fever with maculopapular rash then follow the algorithm given below:

Fever with maculopapular rash

Look at the rash and it's distribution

Central distribution with fever

Peripheral distribution with fever

❑Viral exanthem ❑Lyme disease❑Still disease

Look for target lesion

Present

Absent

Stevens-Johnson Syndrome

Erythema Multiforme

Lyme disease

Characteristics: ❑ Usually as a result of drug reaction ❑Diffusely distributed target lesions including the palms and soles ❑ Mucous membrane may be involved ❑Toxic appearing patient ❑Fever

Characteristics: ❑ Usually autoimmune ❑May follow Herpes simplex, Mycoplasma, Fungal diseases or may occur due to drug exposure (sulfa drugs, anticonvulsants, antibiotics) ❑ Mucous membrane not involved in EM minor ❑In EM major significant involvement of mucous membrane ❑Nonspecific upper respiratory tract infection, moderate fever, general discomfort, cough, sore throat, vomiting, chest pain, diarrhea may occur before the onset of rash ❑Rash may be seen in the palms, soles,face, and extensor surfaces and eye involvement in 10%

Characteristics: ❑ Usually there is a history of travelling to wooden area ❑Tick-borne illness is caused by Borrelia burgdorferi ❑A big lesion with dark red border and central clearing known as erythema migrans ❑Migratory arthalgia ❑Atrioventricular Nodal block ❑Mylagia ❑fever ❑Bell’s palsy ❑Confusion ❑Meningitis
