Surgery-induced acute postoperative pain and stress response can lead to prolonged convalescence. The present study was designed to investigate the effects of intraoperative dexmedetomidine on postoperative analgesia and recovery following abdominal hysterectomy surgeries. Sixty-four patients scheduled for abdominal hysterectomy under general anesthesia were divided into two groups that were maintained using propofol/remifentanil/dexmedetomidine (PRD) or propofol/remifentanil/saline (PRS). During surgery, patients in the PRD group had a lower bispectral index (BIS) value, which indicated a deeper anesthetic state, and a higher sedation score immediately after extubation than patients in the PRS group. During the first 24 hours post-surgery, PRD patients consumed less morphine with patient-controlled analgesia (PCA) and had lower scores on a visual analogue scale (VAS) than their controls from the PRS group. The global 40-item quality of recovery questionnaire and 9-question fatigue severity score both showed higher recovery scores from day 3 after surgery in the PRD group. with the data are considered together, intraoperative administration of dexmedetomidine appeared to promote the analgesic properties of morphine-based PCA and to expedite recovery following surgery in patients undergoing abdominal hysterectomy.

Pain is the central symptom in endometriosis and often persists despite treatment of the disease. Multiple mechanisms underlie endometriosis-associated pain including nociception, inflammation, and alterations in peripheral and central nervous system pain processing. As also occuring in other chronic conditions, pain in endometriosis is often associated with psychological distress and fatigue, both of which may amplify pain. It is hoped that in the future methods of phenotyping women on the basis of the underlying pain mechanisms will be developed, likely combining a critical evaluation of clinical symptoms and signs with laboratory and imaging tests. Optimal pain relief for an individual is more likely if her specific contributory pain mechanisms are identified and appropriately addressed. Such methods may also improve the selection of patients for clinical trials, potentially increasing the probability of identifying novel treatments for the many women with endometriosis for whom acceptable analgesia is not achieved.

Poor sleep is an increasingly recognised problem with chronic pain and further increases the effect on daily function. To identify the relationship between chronic pain, opioid analgesia and sleep quality, this study investigated activity and sleep patterns in patients taking opioid and non-opioid analgesia for chronic back pain. Thirty-one participants (10 healthy controls, 21 patients with chronic pain: 6 on non-opioid medication; 15 on opioid medication) were assessed using actigraphy, polysomnography and questionnaires. Patients with chronic pain subjectively reported significant sleep and wake disturbances as shown by decreased overall sleep quality (Pittsburgh Sleep Quality Index, p < 0.001), increased symptoms of insomnia (Insomnia Severity Index, p < 0.001) and increased fatigue (Fatigue Severity Scale, p = 0.002). They also spent increased time in bed (p = 0.016), took longer to get to sleep (p = 0.005) and had high interindividual variability in other measures of activity but no overall irregular rest-activity pattern. Patients on high doses of opioids (> 100 mg morphine-equivalent/day) demonstrated distinctly abnormal brain activity during sleep suggesting that polysomnography is necessary to detect sleep disturbance in this population in the absence of irregular rest-activity behaviour. Night-time sleep disturbance is common in individuals suffering from chronic pain and may be further exacerbated by opioid treatment. Considerations must be made regarding the appropriate use of combined actigraphy and miniaturised polysomnography for future population-based studies.

Methemoglobinemia can cause life-threatening hypoxia associated with cyanosis and dyspnea not responsive to oxygen. We present a case of recurrent methemoglobinemia because of occult use of topical benzocaine to the vulva. A 47-year-old female with medical history of vulvar cancer and HIV undergoing chemoradiation was sent by the oncology clinic to the emergency department for worsening dyspnea, fatigue, hypoxia to 78% on room air, and gradual onset of cyanosis over the past week. A methemoglobin (MetHb) level was 49%. She received methylene blue, and repeat MetHb levels initially decreased but later increased to 56% despite continued treatment. Additional interviews with the patient revealed she was applying vagicaine (20% benzocaine), an over the counter preparation to the vulvar area for analgesia, and she continued application while hospitalized. She received a total of 6 mg/kg methylene blue and underwent vaginal lavage with 60 mL of sterile saline and cleansed with soapy water. Cyanosis, hypoxia, and dyspnea resolved, and the MetHb level decreased to 5.4% on the day of discharge. Benzocaine is a frequent cause of iatrogenic methemoglobinemia. In this case, additional medication inquiries were helpful in making the diagnosis. Many patients do not consider over-the-counter medications to be potentially harmful. Methemoglobinemia from occult topical benzocaine administration to the vulva is an uncommon exposure route. Occult medication use can be a source of methemoglobinemia.

Patients diagnosed with breast cancer may have supportive care needs for many years after diagnosis. High quality multidisciplinary care can help address these needs and reduce the physical and psychological effects of breast cancer and its treatment. Ovarian suppression and extended endocrine therapy benefits are associated with vasomotor, musculoskeletal, sexual and bone density-related side effects. Aromatase inhibitor musculoskeletal syndrome is a common reason for treatment discontinuation. Treatment strategies include education, exercise, simple analgesia and a change to tamoxifen or another aromatase inhibitor. Chemotherapy-induced alopecia may be a constant reminder of breast cancer to the patient, family, friends, acquaintances and even strangers. Alopecia can be prevented in some patients using scalp-cooling technology applied at the time of chemotherapy infusion. The adverse impact of breast cancer diagnosis and treatment on sexual wellbeing is under-reported. Identification of physical and psychological impacts is needed for implementation of treatment strategies. Fear of cancer recurrence reduces quality of life and increases distress, with subsequent impact on role functioning. Identification and multidisciplinary management are key, with referral to psychosocial services recommended where indicated. The benefits of exercise include reduced fatigue, better mental health and reduced musculoskeletal symptoms, and may also include reduced incidence of breast cancer recurrence. Identification and management of unmet supportive care needs are key aspects of breast cancer care, to maximise quality of life and minimise breast cancer recurrence.

Chronic pain is one of the most common conditions seen in the clinic, and it is often one of the most frustrating for both clinicians and patients. This condition stems from common comorbidities, including depression, insomnia, fatigue, and physical deconditioning, which often create barriers to recovery. In addition, chronic pain has had divergent approaches for treatment, including an overemphasis on analgesia and curative treatments while underemphasizing the biopsychosocial needs of those in pain. This article attempts to provide an initial framework for approaching those in pain and initiating patient-centered options to support improvements in pain, function, and self-care.

Understanding of the causes and underlying mechanisms of pain in people with RA is rapidly changing. With the advent of more effective disease modifying drugs, joint inflammation is becoming a more treatable cause of pain, and joint damage can often be prevented. However, the long-term prognosis for pain still is often unfavourable, even after inflammation is suppressed. Pain is associated with fatigue and psychological distress, and RA pain qualities often share characteristics with neuropathic pain. Each of these characteristics suggests key roles for central neuronal processing in RA pain. Pain processing by the central nervous system can maintain and augment RA pain, and is a promising target for future treatments. Inflammatory mediators, such as cytokines, may provoke central pain sensitisation in animal models, and both local and systemic inflammation might contribute to central pain augmentation in RA. Controlled trials of treatments that target central pain processing have shown some benefit in people with RA, and might be most effective in individuals for whom central pain augmentation plays a key role. For people with RA who experience persistent pain, identifying underlying pain mechanisms critically determines the balance between escalation of anti-inflammatory and disease-modifying treatments and other strategies to provide symptomatic analgesia.

A 61-year-old woman was introduced for consultation with a chief complaint of frequent vomiting. CT revealed a pancreatic body cancer approximately 40mm in size; an invading stenosis from the horizontal part of the duodenum to the jejunum, superior mesenteric artery, and portal vein, splenic vein obstruction, lymphadenopathy, and some ascitic fluid. We diagnosed a passage disorder due to the invasive stenosis from the horizontal part of the duodenum of the pancreatic body cancer to the jejunum, and subsequently performed a duodenum and jejunum bypass operation. We controlled cancer pain with opioid analgesia, and S-1 monotherapy was chosen as the primary chemotherapy. A tendency to increase and the cancer pain of the tumor was aggravated when 5 courses took effect, so gemcitabine plus nab-paclitaxel(GEM plus nab-PTX)therapy was chosen as the second-line chemotherapy because of adverse Grade 3 events due to difficulties with S-1 internal use. We tapered off the opioid analgesia dosage because the cancer pain was relieved after 1 course. The imaging top indicated stable disease at the end of 5 courses, but the pain was relieved so opioid pain killers were unnecessary. Foreign continuation is under treatment with 10-course GEM plus nab-PTX therapy after initial diagnosis. Currently, the patient has undergone 5 courses of S-1 for approximately 18 months, and has achieved stable disease. The only adverse events were nausea, fatigue, Grade 1 malaise, and Grade 2 alopecia, as detected with imaging.

Pain and fatigue are the most common problems reported by women in the early postpartum period. Pain can interfere with a woman's ability to care for herself and her infant. Untreated pain is associated with a risk of greater opioid use, postpartum depression, and development of persistent pain. Nonpharmacologic and pharmacologic therapies are important components of postpartum pain management. Because 81% of women in the United States initiate breastfeeding during the postpartum period, it is important to consider the drug effects of all prescribed medications on the mother-infant dyad. Multimodal analgesia uses drugs that have different mechanisms of action, which potentiates the analgesic effect. If opioids are included, a multimodal regimen used in a stepwise approach allows for administration of lower doses of opioids. Given interindividual variation in metabolism of opioids, as well as the risk of maternal and neonatal adverse effects in women who are ultra-rapid metabolizers of codeine, monitoring for excessive sedation and other adverse effects in infants is prudent for women who are prescribed opiates. Although the U.S. Food and Drug Administration recommendations underscore the need for anticipatory guidance regarding opioid effects in all patients, obstetrician-gynecologists and other obstetric care providers should ensure that the application of this guidance does not interfere with pain control or disrupt breastfeeding during the postpartum period. Women with opioid use disorder, women who have chronic pain, and women who are using other medications or substances that may increase sedation need additional support in managing postpartum pain.
