Spontaneous Spread of Limb Complex Regional Pain Syndrome to the Ipsilateral Face With Ultimate Corneal Abrasion: A Case Report.

Complex regional pain syndrome (CRPS) has the potential to spread from the initial site to distant areas of the body. However, there is a paucity of data reporting the patterns and underlying cause of the spread. This case describes spontaneous, ipsilateral spread of CRPS from the right lower extremity to the orbit, leading to corneal abrasion.

Postoperative Analgesic Requirement and Pain Perceptions after Nonaerodigestive Head and Neck Surgery.

Objectives: Little data exist on associations between patient factors and postoperative analgesic requirement after head and neck (H&N) surgeries. Such information is important for optimizing postoperative care considering concerns regarding opioid misuse. We analyzed factors associated with narcotic use and pain perception following H&N surgery sparing the upper aerodigestive tract.

Multimodal Analgesia Protocol after Head and Neck Surgery: Effect on Opioid Use and Pain Control.

Objective: To assess the effect that implementation of a multimodal analgesic plan has on opioid requirements and pain control in head and neck (H&N) surgery patients.

Study Design: Prospective cohort.

Setting: Tertiary academic hospital.

Treating Opioid Dependence: Pain Medicine Physiology of Tolerance and Addiction.

Inappropriate and excessive opioid prescribing practices for treatment of chronic nonmalignant pain contributed to rising rates of opioid related mortality. Effective and widely available opioid addiction treatment resources are needed to ensure successful resolution of the "opioid epidemic". This chapter outlines the basic pathophysiology of addiction as well as principles of opioid addiction management focusing on the pharmacological and nonpharmacological aspects of care.

Principles of Burn Pain Management.

This article describes pathophysiology of burn injury-related pain and the basic principles of burn pain management. The focus is on concepts of perioperative and periprocedural pain management with extensive discussion of opioid-based analgesia, including patient-controlled analgesia, challenges of effective opioid therapy in opioid-tolerant patients, and opioid-induced hyperalgesia. The principles of multimodal pain management are discussed, including the importance of psychological counseling, perioperative interventional pain procedures, and alternative pain management options.

Piloting a Text Message-based Social Support Intervention for Patients With Chronic Pain: Establishing Feasibility and Preliminary Efficacy.

Objectives: To examine preliminarily the effectiveness of a short message service (SMS) text message-based social support intervention for reducing daily pain and pain interference levels, improving affect and perceptions of social support in patients with chronic noncancer pain, and exploring the feasibility of a novel mobile application to track perceptions of pain and pain interference.

Materials And Methods: Participants (17 men, 51 women) from 2 pain clinics in New York City downloaded a pain tracking application (App) on their Smartphone and used it to record twice-daily pain, pain interference, and affect scores over the 4-week study period. Participants were randomly assigned to receive standard care (control) or standard care along with receipt of twice-daily supportive SMS text messages delivered during the second and third week of the study (intervention).
