Case Study
#1
Clinical
history: An HIV positive male presented in clinic with
confusion and disorientation. He had a fever 38.5°C and
photophobia. His CD4 T cell count was 80/ul. An MRI and lumbar
puncture were performed. The MRI showed various small lesions
within the brain. CSF analysis indicated 32 White Blood Cells/ul
with 89% lymphocytes, and 6% monocytes, glucose of 22mg/dl, and
protein of 89mg/dl. Gram stain showed yeast and India ink negative
stain showed a thick capsule.

A 40-year-old male called 911 stating that he was having difficulty breathing and felt too nauseous to drive himself to the hospital. He said he had type I diabetes and had not been able to afford insulin on a consistent basis, especially over the past week, since he lost his job. Fortunately, the emergency medical team promptly got to the patient and took him to the hospital. His blood work revealed an exceedingly high blood glucose level, a finding consistent...
