HCV infection should be considered in the differential diagnosis of a variety of neurologic disorders. Further studies are necessary to establish the full spectrum of the neurologic complications, identify specific pathophysiologic mechanisms, and provide clear guidelines for management.

Abstract-The psychosocial toll of caring for an individual with dementia is an important, if understudied, concept. For practitioners and researchers alike, understanding the relation between patient characteristics and different facets of caregiver burden is important for guiding treatment and prevention efforts. The current study analyzed the dimensions of caregiver burden and the relation between caregiver burden and results of neuropsychological testing. Participants included 243 dyads of caregivers and Veterans referred for neuropsychological evaluation. Caregivers completed the Zarit Burden Interview (ZBI) to assess caregiver burden. Patients completed a battery of neuropsychological tests measuring the domains of attention/processing speed, memory, language, and executive functioning. A principal components analysis of the ZBI revealed a three-factor structure: psychosocial burden, dependency burden, and guilt. Correlations with neuropsychological test performance by Veteran patients suggested that test performance in the memory, attention, processing speed, executive functioning, and emotional functioning domains were solely related to the caregiver dependency burden factor of the ZBI. Additional analyses suggested severity of dementia and number of tests in the impaired range further influenced reported caregiver burden. The current study is one of the few studies examining caregiver burden in relation to neuropsychological functioning in a mixed clinical sample and has important implications for clinical practice.

The authors report a case of fungal otitis media complicated by extension of the infection into adjacent structures causing apical petrositis and subsequently involvement of the jugular foramen in a 71-year-old diabetic man. First described in 1907, Gradenigo’s syndrome is a serious but rare clinical triad of acute otitis media, unilateral pain in the distribution of cranial nerve V (trigeminal) and ipsilateral cranial nerve VI (abducens) palsy that commonly presents without all three features and is therefore often missed. In this report, our patient was initially misdiagnosed as having a diabetic cranial neuropathy, and later he developed Vernet’s syndrome. Despite aggressive surgical and medical management, he did poorly and died a few weeks later. Clinicians need to be aware of this serious and life-threatening complication of otitis media in high-risk individuals with diabetes or immunocompromised states, to allow early diagnosis and improved clinical outcomes.
