Metabolic Alkalosis - Differential Diagnosis Algorithm
 • Cl- responsive metabolic alkalosis

Metabolic Alkalosis - Differential Diagnosis Algorithm • Cl- responsive metabolic alkalosis - Kidney loss of Cl-: Remote use of loop or thiazide diuretics, Post-hypercapneic metabolic alkalosis - Loss of Cl- outside the kidneys: Gastrointestinal (Vomiting/nasogastric suction, Congenital chloride diarrhea), Sweat (Cystic fibrosis) • Cl- resistant metabolic alkalosis - Normal/low blood pressure: Active diuretic use, Bartter syndrome, Gitelman syndrome, Hypomagnesemia - Hypertension: Increased mineralocorticoid or mineralocorticoid-like effect) • Normal gap metabolic acidosis: Chronic diarrhea, Kidney tubular acidosis • Anion gap metabolic acidosis: Diabetic ketoacidosis, Starvation ketoacidosis, Alcoholic ketoacidosis, D-lactic acidosis, Chronic salicylate poisoning • Normal acid-base status: LiCl use #Metabolic #Alkalosis #Differential #Diagnosis #Algorithm #causes

Echinococcus Life Cycle 1) Adult in small intestine eggs 2) Embryonated egg in feces 3) Oncosphere hatches; penetrates intestinal wall 4) Hydatid cyst in various organs (commonly liver and lung) 5) Protoscolex from cyst 6) Scolex attaches to intestine #Echinococcus #LifeCycle #diagnosis #pathophysiology #infectiousdiseases #cdc #parasite

Anisakiasis - Life Cycle Anisakis, Pseudoterranova, Contracecum 1) Definitive hosts excrete unembryonated eggs in 2a) Eggs become embryonated in water and L3 larvae form in the eggs. 2b) L3 larvae hatch from eggs as ensheathed, free-swimming forms. 3) Free-swimming larvae are ingested by crustaceans, and develop in the hemocoel. 4) Infected crustaceans are eaten by fish or cephalopod paratenic hosts. L3 larvae released in digestion migrate to the mesentery and muscle tissues, and can be transferred to other paratenic hosts via predation. 5) Paratenic hosts maintain L3 larvae in tissues, which are infective to definitive hosts. 6) Marine mammal definitve hosts ingest fish/squid paratenic hosts, and L3 larvae develop into adults in the gastric mucosa. 7) Transmission to humans via raw or undercooked seafood consumption. Diagnosis of anisakiasis can be made by gastroscopic examination during which the larvae can be removed. #LifeCycle #diagnosis #pathophysiology #infectiousdiseases #cdc #parasite

How much sodium is in 1 Liter of Normal Saline? In Bags if Potato Chips
How much sodium is in 1 Liter of Normal Saline? In Bags if Potato Chips 1 L of normal saline = 0.9% sodium chloride contains 154 meq of sodium per liter. 1 L normal saline x (154 meq/L) x (23 mg Na+/meq) = 3,542 mg Na A 1 oz. bag of Lay's Classic potato chips contains 180 mg of sodium. Thus, 1 L of normal saline has about as much sodium as 20 bags of chips. Bryan Carmody @jbcarmody #bags #chips #lays #normal #saline #ns #nephrology #sodium #comparison #hotdogs #conversion

Bullous Pemphigoid - Diagnosis and Management Summary Pathophysiology: Autoantibody-mediated damage to epithelial basement membrane -> separation of epidermis from dermis Clinical Signs/Symptoms/Exam findings: - Prodrome: pruritic, inflammatory plaques (may resemble eczema or urticaria) weeks to months bullous phase - Bullous phase: tense 1-3 cm bullae, often pruritic. Most commonly located on trunk, flexural surfaces, and axillary and inguinal folds - Erosions and crusts at sites of ruptured bullae - Mucous membrane involvement with blisters/erosions in ~20% Management: 1. High-potency topical steroids 2. Systemic glucorticoids if 1) not feasible CMC IM Residency @CMC_IM #Bullous #Pemphigoid #Diagnosis #Management #dermatology
