Social policy is a reflection of changing ideological stances; and ideological stances are influenced by social conditions and events. Policy-makers and social welfare administrators need to be acutely aware of the existing ideologies and the subtle or dramatic shifts as they occur and affect perceptions of clients, programmatic components, and the nature of social service delivery. The author offers a dichotomy of ideological positions as they are applied to the issues of social problems vs sub-populations, societal vs individual responsibility, residual vs institutional welfare, enforceable rights vs revocable privilege, existential vs preferential attention to social needs, government regulation vs deregulation, and governmental aid vs voluntary philanthropy.

We report a case of epidural abscess due to Haemophilus parainfluenzae. This microorganism is a normal inhabitant of the upper respiratory tract that causes endocarditis and, rarely, other invasive infections. To the best of our knowledge, epidural abscess due to H. parainfluenzae has not been reported previously. A 74-year-old man presented with neck pain and subsequently developed incomplete quadriparesis. A cervical epidural abscess and vertebral osteomyelitis were detected by radiologic studies. Surgical drainage and antibiotic therapy resulted in resolution of the abscess and osteomyelitis, and the neurologic sequelae were minimal. Cultures of the purulent material from the abscess yielded H. parainfluenzae. Descriptions in the literature of infections caused by H. parainfluenzae and the antimicrobial agents used for treatment of these infections are reviewed.
