The patient, who is a construction worker, was at work when he suddenly experienced severe pain in his arms, legs, chest, and back. He has experienced this before and was treated 2 months ago for a similar concern. His temperature is 100F 37.8C, blood pressure is 12768 mmHg, pulse is 120min, respirations are 17min, and oxygen saturation is 98 on room air. Physical exam is notable for tenderness to palpation of the patients legs, chest, abdomen, and arms. Laboratory values are obtained and shown below.Hemoglobin: 10 gdLHematocrit: 30Leukocyte count: 8,500mm3 with normal differentialPlatelet count: 199,000mm3Serum:Na: 139 mEqLCl-: 100 mEqLK: 4.9 mEqLHCO3-: 25 mEqLBUN: 23 mgdLLDH: 327 ULGlucose: 99 mgdLCreatinine: 1.1 mgdLCa2: 10.2 mgdLAST: 12 ULALT: 10 ULWhich of the following is the most likely diagnosis?? A: Autoimmune hemolysis, B: Avascular necrosis, C: Infarction of a major organ, D: Infection of the bone, E: Microvascular occlusion,  <response>: Based on the information provided, the key findings are:- 23-year-old male construction worker with severe pain in arms, legs, chest and back, similar to previous episode 2 months ago - Fever of 100F, tachycardia, tenderness on physical exam- Normal WBC count, normal electrolytes- Mildly decreased Hgb and Hct, mildly increased LDH- Normal liver enzymes and calciumThis presentation is most consistent with recurrent episodes of severe pain, fever, and evidence of tissue damage based on mild anemia and increased LDH. The distribution of pain and lack of focal findings makes infection less likely. The normal calcium and liver enzymes go against avascular necrosis or infarction of a major organ. There is no evidence to support autoimmune hemolysis.Therefore, the most likely diagnosis is microvascular occlusion, which can cause recurrent episodes of ischemia and tissue damage.E: Microvascular occlusion
