Pain control in critical limb ischemia (CLI) varies considerably between individuals. ⋯ BUP-TTS is efficacious in the control of pain in patients with CLI. The homozygous AA carriers of the CYP3A4 gene respond better to treatment with BUP-TTS.

This study aimed to identify the following: (1) the proportion of the defensive high-anxious personality type in a chronic pain population; (2) whether personality type affects the relationships between cognitive factors and disability. ⋯ The interaction between defensiveness and anxiety plays an important role in patients' perceptions of, and outcomes from, chronic pain. Differentiating the defensive high-anxious group revealed different patterns of relationship between a range of cognitive factors and disability. This highlights the necessity of assessing personality characteristics that include defensiveness in order to identify those individuals who may be more vulnerable to cognitive factors influencing their perceptions of disability. If personality type is identified as a predictor of poor adjustment, interventions could be customized to the unique needs of this group (eg. high defensive and anxious individuals).

Randomized Controlled Trial
Local Administration of Methylcobalamin and Lidocaine for Acute Ophthalmic Herpetic Neuralgia: A Single-Center Randomized Controlled Trial.
To determine the therapeutic efficacy of combined methylcobalamin and lidocaine for acute ophthalmic herpetic neuralgia (AOHN). ⋯ Methylcobalamin combined with lidocaine mediated detumescence and improved cutaneous healing of the affected area, as well as a significant and sustained analgesic effect on AOHN. The incidence of PHN was also significantly decreased. Local methylcobalamin intervention within 4 to 7 days of onset may be an effective therapeutic option for AOHN.

Ketamine is a commonly used analgesic agent in the management of both acute and chronic pain. While dose-dependent side effects are well described, allergy to ketamine is extremely rare. ⋯ This case represents a likely immunoglobulin E-mediated type I hypersensitivity reaction to ketamine, supported by elevated tryptase levels and positive intradermal skin testing. The interpretation of these results and likely mechanism of the hypersensitivity reaction are described. The patient and treating team were advised against subsequent use of ketamine, due to the risk of serious adverse systemic reaction with repeat exposure.
