Two Patients Experience Same-Day Analgesic Effect of Methadone on Trigeminal Neuralgia Secondary to Malignancy: A Case Report.

Trigeminal neuralgia (TN) secondary to malignancy leads to significant distress and subsequently impacts a patient's quality of life. Use of methadone as a first-line opioid analgesic in this subset of oncology patients is uncommon and is rarely initiated after traditional first-line therapies have failed. We report two patients with TN secondary to tumor burden who experienced significant analgesia within 24 hours of methadone initiation.

Lucid Dreams Associated with Pregabalin: Implications for Clinical Practice.

Here, we describe a case of a patient with multiple myeloma who reported symptoms of lucid dreams. This patient was taking methadone for neoplasm related pain. The patient was also taking pregabalin which was initially started at dosing of 50 mg taken orally three times a day. Five days after initiation of pregabalin, the dosing was increased to 100 mg taken orally three times daily. The patient developed lucid dreams during a hospital stay and methadone was initially thought to be the cause of her lucid dreams. Methadone dosing was decreased with no success, and her lucid dreams persisted. On the patient's thirteenth day of hospital admission, the pregabalin dose was decreased from 100 mg three times a day to 75 mg twice daily. Five days later, the pregabalin was decreased from 75 mg twice daily to 50 mg twice daily. Pregabalin was continued for five more days and then discontinued. Resolution of the lucid dreams occurred following discontinuation of pregabalin. To our knowledge, this is the first reported case of an association between pregabalin and lucid dreams. Given that pregabalin is a widely used medication, we found this case to be relevant to describe this unique presentation.

Neurologic Complications: Effects of Ipilimumab and Nivolumab Therapy in Patients With Metastatic Melanoma.

Checkpoint inhibitors are a form of immunotherapy that have revolutionized treatment for malignant melanoma, resulting in longer survival and better disease control. Multiple autoimmune disorders can occur with the use of checkpoint inhibitors, including severe, potentially fatal neurologic complications. Although neurologic complications are uncommon, their early recognition and treatment is required. The purpose of this article is to present information on neurologic complications of ipilimumab and nivolumab to inform nursing practice. Recommendations for evaluation and treatment of neurologic complications are reviewed.

Opioid-Induced Hyperalgesia: Clinical Implications for Advanced Practice Nurses in Oncology.

Opioid-induced hyperalgesia (OIH) is a key factor in the clinical management of patients experiencing pain. However, limited knowledge exists regarding the specific mechanisms involved in OIH and its treatment. A thorough assessment is usually required, and clinical diagnosis is mainly determined by exclusion in medical practice. Patients who are taking opioids should receive ongoing, comprehensive assessment by a clinician. Early identification of OIH will lead to improved patient outcomes.

5-Fluorouracil toxicity and dihydropyrimidine dehydrogenase enzyme: implications for practice.

5-fluorouracil (5-FU) is a fluorinated pyrimidine analog, which is commonly used in combination chemotherapy for treating solid tumors. Dihydropyrimidine dehydrogenase plays an important role in catabolism and clearance of 5-FU. Any alteration in that sequence of enzymatic activity can lead to toxicity and even death in some patients. The most common loss of a functional allele of the dihydropyrimidine gene is the splice-site mutation c.1905+1G>A, which leads to deficiency of the enzyme. However, because of the small percentage of the population in which the deficiency occurs, routine screening is not recommended, and commercial testing is costly. Treatment measures for 5-FU toxicity are mainly supportive, including palliation of symptoms. Good patient assessment and education are imperative to early treatment of 5-FU-induced toxicity. Advanced oncology practitioners and oncology nurses should thoroughly educate patients and their caregivers on both the common and adverse side effects of 5-FU-based therapy and when it may be necessary to immediately contact their healthcare provider.
