Relationship of functional status of persons having chronic ‘non-affective psychosis’ with anxiety, depression and self-esteem of family caregivers

Abstract

Acute pain associated with herpes zoster (HZ) is the most debilitating symptom, which if not treated in early phase may lead to postherpetic neuralgia (PHN), a potentially crippling disorder with prolonged intractable chronic pain. The socioeconomic consequences secondary to prolonged severe pain include decreased socialization, depression, fatigue, restricted daily activities, and poor quality of life. HZ and PHN impose a significant economic burden in the form of direct inpatient care and loss of productivity. Early interventional treatments attenuate central sensitization by interrupting the transmission of nociceptive afferent impulses to the central nervous system and minimize nerve damage by improving blood flow to the nervous tissue in addition to the local anti-inflammatory action of corticosteroids. Interventions treatment options have been increasingly used as a part of multimodal approach in the management of acute pain of HZ in addition to pharmacological agent. This article reviews the various interventional treatment options which have used in the recent years for the management of acute pain of HZ and subsequent prevention of PHN.
