Atypical chest pain is a common complaint among Complex Regional Pain Syndrome (CRPS) patients with brachial plexus involvement. Anatomically, the intercostobrachial nerve (ICBN) is connected to the brachial plexus and innervates the axilla, medial arm and anterior chest wall. By connecting to the brachial plexus, the ICBN could become sensitized by CRPS spread and become a source of atypical chest pain. ⋯ The results of this study support the idea that chest pain is greater in CRPS patients than normal controls. The ICBN could be the source of this sensitization by CRPS spread from the brachial plexus.

For many headache types, occipital peripheral nerve stimulation (ONS) provides significant relief of chronic, frequent, and severe headaches. Though rarely reported, ONS may cause painful muscle spasms that make stimulator use impractical. The classic description of the technique advocates placement of the leads transversely at the level of the arch of C1 or at C1-2. At that level, the greater occipital nerve (GON) infrequently pierces the superficial fascia of the neck muscles to become superficial. However, important anatomic variability exists. ⋯ Stimulation parameters vary, thus posting parameters may be misleading as muscle spasms occurred despite multiple reprogramming attempts and were a function of lead position, not program settings.

Pain is a common problem in older age and strongly interacts with neuropsychiatric disorders. In this paper we studied the prevalence of pain and the connection between pain and neuropsychiatric comorbidities among older nursing home residents. ⋯ It is important when assessing pain to consider the patient's neuropsychiatric status and especially communication abilities. The information above helps understand the variances in pain parameters in neuropsychiatric patients and may ultimately lead to better pain management in these difficult patients.

Herpes zoster radiculopathy treated with fluoroscopically-guided selective nerve root injection.
Varicella-zoster virus, a member of the herpes virus family, is a neurotrophic virus that primarily affects afferent sensory neurons. Reactivation of latent virus within the dorsal root ganglion and axoplasmic transport to epithelial nerve terminals causes the segmental cutaneous rash and neuralgic pain characteristic of herpes zoster. ⋯ Cases of herpes zoster-induced radiculopathy may become more frequent, as evidenced by the increasing number of cases of herpes zoster in the United States noted epidemiologically.

Antidepressants are prescribed in a wide range of doses to treat both depression and chronic pain, with optimal psychopharmacology individualized for each patient. In the past decade more antidepressants from different chemical classes have become available and are being used for the treatment of both chronic pain and depression. ⋯ The data suggest that in the context of multimodal treatment for chronic pain, antidepressant therapy at both low and therapeutic doses demonstrates similar response rates. Tricyclic antidepressants (TCAs), which include secondary and tertiary amines, as well as SSRI/SNRIs and atypicals, all appear to show similar favorable response rates.
