Horner Syndrome induced by toxoplasmosis infection in a patient with AIDS and disseminated herpes simplex virus.

Purpose: This case report describes a case of Horner syndrome resulting from central nervous system (CNS) toxoplasmosis in an immunocompromised patient. Horner Syndrome is a neurological condition characterized by unilateral miosis, ptosis with apparent enophthalmos, and anhidrosis due to inhibition of the sympathetic pathway. The ocular sympathetic pathway runs from the posterolateral hypothalamus to the ophthalmic branch of the trigeminal nerve (cranial nerve V1).

Presentation and care of a family with Huntington disease in a resource-limited community.

Background: In high-income countries patients with Huntington disease (HD) typically present to healthcare providers after developing involuntary movements, or for pre-symptomatic genetic testing if at familial risk. A positive family history is a major guide when considering the decision to perform genetic testing for HD, both in affected and unaffected patients. Management of HD is focused upon control of symptoms, whether motor, cognitive, or psychiatric.
