Persistent pain is a common side effect of breast cancer treatment. The present study aimed to assess the prevalence, associated treatment-related factors, and the type of pain (neuropathic or nociceptive) in patients who had undergone a unilateral mastectomy. ⋯ Persistent pain after breast cancer treatment continues to have a high prevalence. Our results indicate that the largest proportion of patients experiencing persistent pain after breast cancer treatment do not have a clear neuropathic pain component.

Palliative care clinicians are increasingly involved in the care of elderly patients suffering from chronic malignant and nonmalignant illnesses, of which neuropathic pain is a prevalent problem. As a person becomes more frail, pain medications such as opioid analgesics and adjuvant pain medications can result in unwanted effects such as sedation, confusion, and increased risk of falls. ⋯ Methadone is an opioid analgesic that is effective in the treatment of neuropathic pain, is excreted by the bowels, is highly lipophilic, and can be administered through the oral, buccal, or sublingual routes. We present three cases highlighting the use of low-dose adjuvant methadone to manage complex neuropathic pain in the frail elderly.

The differential diagnosis of strictly unilateral hemicranial pain includes a large number of primary and secondary headaches and cranial neuropathies. It may arise from both intracranial and extracranial structures such as cranium, neck, vessels, eyes, ears, nose, sinuses, teeth, mouth, and the other facial or cervical structure. Available data suggest that about two-third patients with side-locked headache visiting neurology or headache clinics have primary headaches. ⋯ Therefore, each suspected secondary headache should be subjected for appropriate investigations or referral. The diagnostic approach of primary side-locked headache starts once one rule out all the possible secondary headaches. We have discussed an algorithmic approach for both secondary and primary side-locked headaches.

Comparative Study
A retrospective study of open thoracotomies versus thoracoscopic surgeries for persistent postthoracotomy pain.
Persistent thoracotomy pain syndrome (PTPS) is a recognized complication and is considered to be less after video-assisted thoracoscopic surgery (VATS) compared with open thoracic surgery (OTS). The primary objective was to compare the incidence of PTPS at 6 months. Secondary objectives were to compare the incidence of neuropathic pain between VATS and OTS and to report perioperative factors associated with the development of PTPS. ⋯ Our study indicates that PTPS is significantly more common and has a higher chance of being neuropathic with OTS. Despite being relatively less traumatic, VATS still carries a significant potential for PTPS. A diagnosis of cancer and history of previous pain are highly predictive of its development.
