  2. Chief Complaint “My chest hurts and I’ve been having trouble breathing.”

  3. History of Present Illness • This is a 46-year-old woman with PMHx of vitiligo, endometriosis, and irritable bowel syndrome, who was in her usual state of health until 2 months prior to admission when she started feeling short of breath, tired and weak. • The patient does report one episode of feeling light headed about 2 months ago in Atlanta while walking her dog. She thought that she was going to pass out but did not lose consciousness. • Following this episode she went to the ED where a work-up failed to explain her symptoms. • She moved to New Orleans about one month prior to admission. Her symptoms continued to worsen She also began to experience intermittent chest pain and shortness of breath that was more pronounced with exertion. Worsening of these symptoms prompted the patient to present to the emergency department.

  4. HPI (continued)… • She described her chest pain as: left sided in location; 6-7/10 in intensity; radiated to the neck and left arm; and associated with shortness breath, nausea, diaphoresis.

  10. Physical Exam: • VITAL SIGNS: • BP-118/84 • HR-103 • Temp- 98.3 • O2 sats on RA-98% • GENERAL: AAO x3. No apparent distress. • HEENT: Positive minimal scleral icterus, and in the soft palate and hypoglossal fossa as well • No appreciated thyromegaly or cervical lymphadenopathy. • No paranasal tenderness. • No oropharyngeal erythema or exudate. • Moist mucous membranes. • Positive skin change and vitiligo to the face. PERRL. EOMI • CARDIOVASCULAR: Regular rate and rhythm. S1, S2 normal. No murmurs,rubs, or gallops appreciated on auscultation. • RESPIRATORY: Clear to auscultation bilaterally. No wheezes, rales, or crackles appreciated.

  11. Physical Exam (continued)… • ABDOMEN: Nondistended. Positive bowel sounds. No hepatosplenomegaly appreciated; nontender to palpation. • EXTREMITIES: No cyanosis, clubbing, or edema. 2+ pulses x4 extremities. Poor capillary refill with resting pallor, positive vitiliginous changes to the bilateral upper extremities and lower extremities with islands of amelanotic patches surrounded by hyperpigmented areas. No rashes, no petechiae.

  12. Physical Exam (continued)…

  13. Chest X-ray

  14. EKG

  15. Laboratory Work Up… 10 97.8 140 N = 3.0 L = 2.7 M = 0.1 E = 0.1 B = 0 6.9 Peripheral Smear: Microcytes, macrocytes + tear drop cell + schistocytes Hypochromic Polychromasia Decreased platelets 103 10 99 82 5.9 3.4 26 0.39 20.7 32.8 Mg = 1.8 Phos = 5.1 RBC = 2.12 MCH = 32.4 Tpro Alb Tbili AST AlkP ALT 7.4 4.9 3.2154 44 77 • Amylase = 19 • Lipase = 25 11.6 21.1 D-dimer = 5640 LDH = 2730 Haptoglobin = 7 Retic % = 0.8 Trop #1 = 0.03 Trop #2 = 0.03 1.0 • Hep Panel = (-) • U/A: 1.008/7.0/+nitrites/+leukocytes/ many bacteria, 3-5 wbc, 2-20 squam, 0 casts

  16. More laboratory work-up… • Iron Profile: Iron = 132 Transferrin = 238 TIBC = 309 Iron Sat = 43 • Methylmalonic acid = 1363 • Homocysteine = 45 • Vit B 12 = <12 • Ferritin = 177.5 • Folate = 15.8 • TSH = 1.45 • ANA = (-)

  17. Chest CT Angiogram • 1. No evidence of intra-arterial pulmonary thrombus. • 2. No pulmonary mass, pneumothorax, pleural effusion, or lymphadenopathy • 3. Mild cardiomegaly.

  18. Abdominal U/S • Hepatomegaly. Heterogeneous hepatic echotexture. This limits evaluation of the underlying hepatic parenchyma and therefore detection of focal abnormality. Further evaluation with contrast-enhanced MRI or CT can be performed as clinically warranted. • The SPLEEN is normal in size and appearance , measuring 11-12 cm. • The left KIDNEY is normal borderline size measuring 13.1 cm. thickness of the parenchyma is normal. No stones are seen. There is no evidence of hydronephrosis. No significant solid masses are noted.

  19. Peripheral Blood Smear

  20. Additional lab data • Celiac Sprue = (-) • Electrophoresis = Normal • A = 95% • A2 = 2.3% • Intrinsic Factor AB = (+)

  21. Hospital Course • Day: 1-2 • Blood Transfusion x 2 with appropriate response • Hematology/Oncology Consult • Vit B12 dose given

  22. Diagnosis… Vitamin B-12 Deficiency secondary to Pernicious Anemia

  23. Follow-Up… • Patient received Vit B12 for 1-1/2 months • At present time the patient’s vitamin B12 levels are within normal limits. • The patient will require vitamin B12 for the rest of her life and should take 1000 mcg of vitamin B12 subcutaneously every month
