Opioid-induced constipation persists as a challenge in the management of chronic pain treated with opioid therapy. Multiple opioid antagonists have been applied in attempt to combat the gastrointestinal side effects of opioid analgesia, however their lipid-soluble nature allows passage into the central nervous system and consequent antagonism of centrally mediated analgesia. In contrast, methylnaltrexone offers the advantage of peripheral receptor-specific opioid antagonism due to chemical alterations conferring greater polarity and less lipid solubility. We present use of enteral methylnatrexone to treat severe opioid-induced constipation in a young boy who had failed treatment with the non-specific opioid antagonist, naloxone. This case reports describes the safe transition from enteral naloxone to enteral methylnaltrexone and discusses the potential risk of relative opioid toxicity during the transition. ⋯ Our case report demonstrates safe transition from enteral naloxone to enteral methylnaltrexone in a pediatric patient, avoiding the serious consequences of relative opioid toxicity. This patient experienced significant improvement of opioid-induced constipation and reduction in opioid requirements and it is possible that other patients would benefit as well. The role of enteral methylnaltrexone deserves further investigation.

Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) syndrome is a rare type of trigeminal autonomic cephalalgia. SUNCT syndrome is typically idiopathic, and secondary SUNCT syndrome after indirect injury is very rare. We report a case of SUNCT syndrome manifested dramatically after a whiplash injury and treated by greater occipital nerve (GON) block. ⋯ Secondary SUNCT syndrome induced by whiplash injury is rare. Our case showed good outcome of SUNCT syndrome treated by GON.

Randomized Controlled Trial
A randomized, placebo-controlled trial of acetaminophen extended release for treatment of post-marathon muscle soreness.
To compare the efficacy of acetaminophen extended release (ER) caplets to placebo in treating muscle soreness after a marathon. ⋯ Acetaminophen ER 1300 mg, a nonprescription drug, was an effective treatment for post-race muscle soreness on the day of the marathon. In addition, acetaminophen ER provided benefit for interference with sleep and overall satisfaction with treatment, and was generally well tolerated.

Multicenter Study
Addressing parental concerns about pain during childhood vaccination: is there enough time to include pain management in the ambulatory setting?
Pain from vaccine injections remains undertreated, despite the availability of numerous pain-relieving strategies. Healthcare providers report lack of time within current office workflows as a major barrier to routine pain management. The objective was to document the total time involved in outpatient vaccine appointments to test the hypothesis that offering pain-relieving strategies can be practically implemented when considering the element of time to vaccine injection. ⋯ Contrary to healthcare provider perceptions, the timing of outpatient childhood vaccine appointments allows for the inclusion of pain management interventions. Efforts should now focus on educating healthcare providers and parents about the value of pain management and how to implement evidence-based strategies.

The objective of the study was to examine patients' experiences of pain in Hospital in the Home (HITH) programs and identify the issues related to providing optimal pain management for acute care patients in the home environment. ⋯ Treatment of pain at home was suboptimal with patients experiencing moderate-to-severe pain and discomfort during the treatment phase of their illness. Lack of appropriate discharge planning strategies meant that patients went home without adequate analgesia and use of nonprescribed pain medication was common. The number of patients transferred home without analgesics indicates a worrying underrecognition of the need for analgesia in this care context and poses a risk to patient safety that is no less significant because patients are at home.
