Has this happened before • Most drug rashes resolve once the with this medication drug is stopped, mild reactions may be treated with creams to decrease (increasing sensitivity) symptoms but serious reactions may require treatment with drugs such as epinephrine (given by injection), diphenhydramine, and/or a corticosteroid to prevent complications.

Macules represent a change in color and are not raised or depressed compared to the skin surface. A patch is a large macule. Examples include freckles, flat moles, and some allergic drug eruptions Macules 13 Common Lesion Types Papules Elevated lesions usually < 10 mm in diameter that can be felt or palpated. Examples include nevi, warts, insect bites, some lesions of acne. Papules 14 7 5/20/2020 Common Lesion Types The term maculopapular is often loosely and improperly used to describe many red rashes; because this term is nonspecific and easily misused, it should be avoided. • Remember a macule is <10mm …the pictured reactions is much bigger. • Additional terms should be used • Confluent: flowing or coming *Maculopapular together also : run together. 15 Common Lesion Types • Hives AKA Urticaria AKA Wheals: • Circumscribed, raised, erythematous plaques, often with central pallor. • Lesions may be round, oval, or serpiginous( wavy margin) in shape and vary in size from less than 10mm to several centimeters in diameter. They are intensely itchy • Individual lesions are transient, usually appearing and enlarging over the course of minutes to hours and then disappearing within 24 hours.

Rationale 25 Summary of Common Lesions portion • A thorough physical assessment utilizing appropriate dermatological terms is critical to assisting physician recommendations and patient safety. • The term maculopapular is commonly misused and should be avoided. • Additional terms like confluent can better describe the reaction’s macular and/or papular presentation. • Remember: macules are flat discolorations and papules are elevated lesions; neither are larger than 10mm. 26 13 5/20/2020 Not all Rashes are Drug Rashes 27 “Nurse, I have a rash and I think it’s because of the medicine!” 28 14 5/20/2020 Objectives 1 Define atypical drug rashes 2 Define why some rashes are not drug rashes 3 Test your knowledge / self‐check 29 • Started anti TB therapy 3 weeks ago • Multiple erythematous papules primarily on wrist and fingers • Symptoms started 3 days ago • Itching worse at night Is this a drug rash? 30 15 5/20/2020 • Started anti TB therapy 3 weeks ago • Multiple erythematous papules primarily on wrist and fingers • Symptoms started 3 days ago • Itching worse at night Is this a drug rash?

  • In Diagnosis Must Be Based on Clinical Signs and Symptoms. in This Paper
    242 POST-GRADUATE MEDICAL JOURNAL August, 1938 Postgrad Med J: first published as 10.1136/pgmj.14.154.242 on 1 August 1938. Downloaded from SOME REMARKS ON DIFFERENTIAL DIAGNOSIS OF BLOOD DISEASES. By A. PINEY, M.D., M.R.C.P. (Assistant Physician, St. Mary's Hospital for Women and Children.) Differential diagnosis of blood diseases has been discussed time and again, but, as a rule, blood-pictures, rather than clinical features, have been taken into account, so that the impression has become widespread that the whole problem is one for the laboratory, rather than for the bed-side. It is obvious, however, that the first steps in diagnosis must be based on clinical signs and symptoms. In this paper, there- fore, certain outstanding clinical features of blood diseases, and various rather puzzling syndromes will be described. The outstanding external sign that leads the practitioner to consider the possi- bility of a blood disease is pallor, which is not quite so simple a state as is often supposed. It is, of course, well known that cutaneous pallor is not an infallible sign of anaemia, but it is often presumed that well-coloured mucous membranes are fairly good evidence that anaemia is not present. This is not necessarily true. The conjunctive may be bright pink in spite of anaemia, because mild inflammationProtected by copyright. may be present, masking the pallor. This is quite frequently due to irritation by eyelash dyes. Similarly, the finger-nails, which used to serve as a reliable index of pallor, are now found disguised with coloured varnish.

Kim, MD, MPH This is the case of a previously healthy 15-month-old girl who initially abstract presented to her primary pediatrician with a 2-week history of intermittent periorbital edema. The edema had improved by the time of the visit, and a urine specimen was unable to be obtained in the clinic. A routine fingerstick demonstrated anemia to 8.8 mg/dL, so the patient was started on ferrous sulfate. She then returned to the emergency department 1 month later with severe periorbital edema and pallor but no other significant symptoms. On physical examination, she was tachycardic with striking periorbital edema and an otherwise normal physical examination. She was noted to have a severe microcytic anemia (hemoglobin of 3.9 mg/dL and mean corpuscular Mattel Children’s Hospital and University of California, Los Angeles, Los Angeles, California volume of 53.1 fL) and hypoalbuminemia (albumin of 1.9 g/dL and total protein of 3.3 g/dL).
