TRX?
Urinary tract infection with PARASITIC BLOOD FLUKE WORK.
S/S:

LATE NEUROSYPHILIS?
EALRY NEUROSYPHILIS
- Meningitis (milder than bacterial)
- Posterior uveitis (decreased visual acuity)
- CNS Vasculitis (infarctions/ischemia)
- Cranial neuropathies (especially optic, facial, auditory)
LATE NEUROSYPHILIS
- Progressive Dementia
- Tabes Dorsalis - Argyll Robinson Pupils (accomodate but don’t constrict with light); Post column/dosal root disease (ataxia, impaired proprioception and vibratory)
HERPANGINA presents similar to hand-foot and mouth disease, but differs in what aspect?
BOTH: painful pharyngeal vesicles in mouth, BUT HFM have anterior vesicles, and Herpangina has posteriorly located vesicles.
