4 Interesting Facts of Rubeola Like MIS-C, characterized by high fever that persists for several days, conjunctival involvement, and diffuse rash Unlike MIS-C, rash typically progresses from head to toe Koplik spots—gray-white punctate spots on buccal mucosa near parotid duct—are pathognomic for measles, if present Diagnosis is confirmed by detection of rubeola IgM in serum
4 Interesting Facts of Septic shock Life-threatening systemic syndrome caused by microbial infection and dysregulated physiologic response Presentation varies depending on source of infection, but includes fever, tachypnea, tachycardia, hypotension, and signs of tissue hypoperfusion Rash, lip changes, ocular changes, and edema of hands and feet are not typical Diagnosis is based on recovery of …
4 Interesting Facts of Primary amyloidosis Primary systemic light chain amyloidosis is a plasma cell dyscrasia caused by a pathologic clonal population of plasma cells in the bone marrow that produce monoclonal light chains that misfold and aggregate into a fibrillar pattern These amyloid fibrils’ monoclonal light chains have a high affinity for visceral organs, …
3 Interesting Facts of Solitary plasmacytoma A solitary plasmacytoma is a single tumor composed of monoclonal plasma cells A solitary plasmacytoma of bone is a plasma cell tumor located only in bone, without other clinical features (ie, myeloma-defining events) of multiple myeloma However, the plasmacytoma itself contains clonal plasma cells that are histologically similar to those …
8 Interesting Facts of Multifocal atrial tachycardia Multifocal atrial tachycardia is a type of supraventricular tachycardia originating from multiple foci and characterized by: Irregular atrial rate greater than 100 beats per minute; typically 110 to 180 beats per minute Organized P waves with at least 3 distinct wave morphologies in the same ECG lead Irregular P-P …
4 Interesting Facts of Paroxysmal supraventricular tachycardia One focus in the atria begins to fire rapidly, overtaking the sinoatrial node Abrupt onset and termination ECG shows P waves different from normal sinus P waves; QRS complex may be wide Differentiated from multifocal atrial tachycardia by ECG findings
Atrial flutter with variable atrioventricular conduction Causes increased heart rate, palpitations, and irregular rhythm Flutter rate is approximately 300 beats per minute; 2:1 atrioventricular conduction, which results in a ventricular rate of 150 beats per minute ECG results show saw-toothed pattern of F waves, especially in leads II, III, aVF, or V₁ Presence of regular P-P …
