Iron-Deficiency Anemia

Case Study

A 72-year-old man developed chest pain whenever he was physically active. The pain ceased on

stopping his activity. He has no history of heart or lung disease. His physical examination was

normal except for notable pallor.

Diagnostic Analysis

The patient was found to be significantly anemic. His angina was related to his anemia. His

normal RBC survival studies and normal haptoglobin eliminated the possibility of hemolysis..

His RBCs were small and hypochromic. His iron studies were compatible with iron deficiency.

His marrow was inadequate for the degree of anemia because his iron level was reduc

AIDS (Acquired Immunodeficiency Syndrome)

Case Studies

The patient, a 30-year-old homosexual man, complained of unexplained weight loss, chronic

diarrhea, and respiratory congestion during the past 6 months. Physical examination revealed

right-sided pneumonitis. The following studies were performed:

Diagnostic Analysis

The detection of Pneumocystis jiroveci pneumonia (PCP) supports the diagnosis of AIDS. PCP is

an opportunistic infection occurring only in immunocompromised patients and is the most

common infection in persons with AIDS. The patient??s diarrhea was caused by Cryptosporidium

muris, an enteric pathogen, which occurs frequently with AIDS and can be identified on a stool

culture. The AIDS serology tests made the diagnoses. His viral load is significant, and his

prognosis is poor.

The patient was hospitalized for a short time for treatment of PCP. Several months after he was

discharged, he developed Kaposi sarcoma. He developed psychoneurologic problems eventually

and died 18 months after the AIDS diagnosis.

Case Studies

Critical Thinking Questions

1. What is the relationship between levels of CD4 lymphocytes and the likelihood of

clinical complications from AIDS?

2. Why does the United States Public Health Service recommend monitoring CD4

counts every 3??6 months in patients infected with HIV?

3. This is patient seems to be unaware of his diagnosis of HIV/AIDS. How would you

approach to your patient to inform about hi
