Women with breast cancer have many adverse symptoms, of which some are specific to premenopausal patients. Management of these common symptoms include non-hormonal drugs, such as antidepressants and antiseizure compounds to alleviate hot flushes. Non-oestrogenic vaginal lubricants seem to moderately decrease occurrence of vaginal dryness and dyspareunia. Transdermal testosterone alone has not been shown to improve libido in these women. Options for fertility preservation include cryopreservation of embryos or oocytes before chemotherapy. Exercise is the one evidenced-based intervention shown to positively affect cancer-related fatigue. However, effective prevention and treatments for peripheral neuropathy and paclitaxel acute pain syndrome remain elusive. Weight-bearing exercise helps to maintain bone strength with adequate intake of calcium and vitamin D. Use of bisphosphonates in women taking aromatase inhibitors (combined with ovarian suppression in premenopausal women) to prevent bone fractures has not been substantiated, although it should be considered in women with osteoporosis. No specific drug has been shown to prevent radiation-induced dermatitis alone. Although some effective treatments can counteract symptoms related to cancer or treatments, research is needed to expand evidence-based care in premenopausal survivors of breast cancer.

Fibromyalgia (FM) is a mysterious pain syndrome with progressive and widespread pain, explicit areas of tender points, stiffness, sleep disturbance, fatigue, and psychological distress without any obvious disease. FM is commonly perceived as a condition of central pain and sensory augmentation. There are documented functional abnormalities in pain and sensory processing in FM. Central sensitization and lack of descending analgesic activity are the 2 leading mechanisms that have been demonstrated by advance in both basic and clinical research. The pathogenesis of FM may also be attributed to the genetic polymorphisms involving serotoninergic, dopaminergic, and catecholaminergic systems. Any psychiatric disorders and psychosocial influences in FM may also affect the severity of pain. The various external stimuli or trigger such as infection, trauma, and stress may all contribute to proceed to presentation of FM. The recent launches of 3 US Food and Drug Administration-approved pharmacotherapy for FM namely pregabalin, duloxetine, and milnacipran have certainly raised the profile of optimal chronic pain management. However, appropriate evaluation and efficacious management of acute pain has not been as well publicized as chronic pain in FM. Acute pain or flare up caused by any trauma or surgery certainly may present a real challenge for patients with FM and their health care providers. Pre-emptive analgesia and pro-active treatment may offer the momentum for acute pain control based on model of central sensitization and pain in FM. This review article on FM appraises the modern practice of multimodal therapy focus on both acute and chronic pain management. Meanwhile, the evolving nonpharmacological approach is summarized and stressed as an essential component of integrated care in FM.

Protecting metallic implants from the harsh environment of physiological fluids is essential to guaranteeing successful long-term use in a patient's body. Chemical degradation may lead to the failure of an implant device in two different ways. First, metal ions may cause inflammatory reactions in the tissues surrounding the implant and, in extreme cases, these reactions may inflict acute pain on the patient and lead to loosening of the device. Therefore, increasing wear strength is beneficial to the performance of the metallic implant. Second, localized corrosion processes contribute to the nucleation of fatigue cracks, and corrosion fatigue is the main reason for the mechanical failure of metallic implants. Common biomedical alloys such as stainless steel, cobalt-chrome alloys, and titanium alloys are prone to at least one of these problems. Vapor-deposited hard coatings act directly to improve corrosion, wear, and fatigue resistances of metallic materials. The effectiveness of the corrosion protection is strongly related to the structure of the physical vapor deposition layer. The aim of this paper is to present a comprehensive review of the correlation between the structure of physical vapor deposition layers and the corrosion properties of metallic implants.

It is generally thought that exercise is beneficial to alleviate pain. However, prolonged movement may lead to the development of painful injuries, because of the overload of low-threshold motor units. Especially in individuals with a pain condition, exercise prescription and the impact of fatigue is less clear. This may be because of the dual effects, aggravation and relief, which fatigue has on pain. The purpose of this review is to ascertain the relation between pain and the motor system, both in the development and management of pain. Recent studies show that fatigue alters pain-induced increases in corticomotor excitability and leads to within and between-muscle adaptations. Studies of acute pain have shown complex adaptations such as increased movement variability, which may be because of a search for motor solutions to prolong overall task performance. In contrast, chronic pain seems to limit movement duration, speed, and variability which could be protective in the short term but also counterproductive over time. Owing to these adaptations in movement strategies, pain chronicity may help to dictate exercise prescription. For example, the correct dosage of multimuscle, dynamic exercises would act to promote movement variability. Thus, it seems that exercise involving the use of different movement strategies could be effective in helping people to obtain exercise-induced benefits while avoiding injury and pain reaggravation.

Recovery from ambulatory surgical procedures can be limited by postoperative pain. Inadequate analgesia may delay or prevent patient discharge and can result in readmission. More frequently, postoperative pain produces discomfort and interrupts sleep, contributing to postoperative fatigue. The development of effective analgesic regimens for the management of postoperative pain is a priority especially in patients with impaired cardiorespiratory, hepatic, or renal function. Tramadol and tapentadol hydrochloride are novel in that their analgesic actions occur at multiple sites. Both agents are reported to be mu-opioid receptor agonists and monoamine-reuptake inhibitors. In contrast to pure opioid agonists, both drugs are believed to have lower risks of respiratory depression, tolerance, and dependence. The Food and Drug Administration has approved both drugs for the treatment of moderate-to-severe acute pain in adults. This article provides an evidence-based account of the role of tramadol and tapentadol in modern clinical practice.

Mechanisms underlying chronic pain differ from those underlying acute pain. In chronic pain states, central nervous system (CNS) factors appear to play particularly prominent roles. In the absence of anatomical causes of persistent pain, medical sub-specialities have historically applied wide-ranging labels (e.g., fibromyalgia (FM), irritable bowel syndrome, interstitial cystitis and somatisation) for what now is emerging as a single common set of CNS processes. The hallmark of these 'centrally driven' pain conditions is a diffuse hyperalgesic state identifiable using experimental sensory testing, and corroborated by functional neuroimaging. The characteristic symptoms of these central pain conditions include multifocal pain, fatigue, insomnia, memory difficulties and a higher rate of co-morbid mood disorders. In contrast to acute and peripheral pain states that are responsive to non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, central pain conditions respond best to CNS neuromodulating agents, such as serotonin-norepinephrine reuptake inhibitors (SNRIs) and anticonvulsants.

Severe pain is usual after laparoscopic ventral hernia repair (LVHR). Mesh fixation with titanium tacks may play a key role in the development of acute and chronic pain and alternative fixation methods should therefore be investigated. This PhD thesis was based on three studies and aimed too: 1) assess the intensity and impact of postoperative pain by detailed patient-reported description of pain and convalescence after LVHR (Study I), 2) evaluate the feasibility of fibrin sealant (FS) for mesh fixation in an experimental pig model (Study II), and 3) investigate FS vs. tacks for mesh fixation in LVHR in a randomised, double-blinded, clinical controlled study with acute postoperative pain as the primary outcome (Study III). In Study I - a prospective descriptive study - 35 patients were prospectively included and underwent LVHR. Scores of pain, quality of life, convalescence, fatigue, and general well-being were obtained from each patient. Follow-up was six months. Average pain from postoperative day (POD) 0-2 and POD 0-6 measured on a 0-100 mm visual analogue scale (VAS) was 61 and 48, respectively. Pain scores reached preoperative values at POD 30. The incidence of severe chronic pain was 7%. No parameter predicted postoperative pain significantly. Significant correlations were found between pain, and general well-being (rS= -0.8, p < 0.001), satisfaction (rS= -0.67, p < quality of life score (rS= -0.63, p < 0.001) six months postoperatively. Patients resumed normal daily activity at POD 14. In Study II - a randomised experimental study in pigs - nine pigs were operated laparoscopically with insertion of two different meshes fixed with either FS or tacks. All pigs were euthanized on POD 30. The primary outcome parameter was strength of ingrowth between the mesh and the anterior abdominal wall. A mechanical peel test was performed for each tissue sample. The secondary outcome parameters were grade and strength of adhesions to the mesh, shrinkage and displacement/folding of the mesh and histological parameters. All nine pigs survived without complications until sacrifice. No meshes were displaced from their initial position at autopsy, but in two cases mesh folding was observed. No significant difference in strength of ingrowth was found between different fixation methods or mesh types. Furthermore, no significant difference was found in grade or strength of adhesions or any histological parameters. In Study III - a randomised, controlled, double-blinded, multicenter trial - 40 patients with umbilical hernia defects between 1.5-5 cm, were randomly assigned to receive FS or titanium tacks for mesh fixation in LVHR. Patients, care givers and those assessing the outcomes were blinded to group assignment. The primary outcome was average pain from POD 0-2 (VAS score). Secondary outcome parameters were fatigue, general well-being and time to resume normal daily activity. Follow-up was one month for all. Patients in the FS group reported significantly less pain at POD 0-2 (median VAS 38 (range 6-98) vs. 60 (18-96), p = 0.01). Absolute VAS score difference between groups was 20 mm (95% CI 4-35 mm) at activity, and 19 mm (95% CI 3-34 mm) at rest. Patients in the FS group reported significantly less discomfort from POD 0-2 and POD 0-10, compared with the tack group. No significant difference was found in fatigue score between groups. No significant difference in hospital stay, hernia diameter, or morphine consumption in the post anesthesia care unit was found between groups. Patients in the FS group resumed normal daily activity at POD 7 (1-66) versus POD 18 (1-95) in the tack group (p = 0.03). No recurrences were observed. No adverse events or side effects were observed. No significant differences in predefined complications were found between groups. In conclusion, pain is a significant clinical problem after LVHR with impact on general well-being, quality of life and patient satisfaction. This issue must have first priority in future ventral hernia repair research. It is now documented, that the simple application of fibrin glue instead of titanium tacks for mesh fixation in LVHR of defects < 5 cm significantly reduced acute pain, discomfort and the period of convalescence. Long-term follow-up will show the value of FS fixation in terms of chronic pain and recurrence. As FS potentially may solve many of the outcome problems associated with LVHR, future studies should include larger hernia defects including large incisional hernias, as the operative technique may be different.

Workplace bullying is defined as the repetitive and systematic engagement of interpersonally abusive behaviors that negatively affect both the targeted individual and the work organization. According to the findings of 12 studies, being bullied in the workplace affects approximately 11 percent of workers. Victims are frequently blue-collar and unskilled workers. However, there also appear to be gender and milieu/management factors. Emotional/psychological consequences of workplace bullying may include increased mental distress, sleep disturbances, fatigue in women and lack of vigor in men, depression and anxiety, adjustment disorders, and even work-related suicide. Medical consequences of workplace bullying may include an increase in health complaints such as neck pain, musculoskeletal complaints, acute pain, fibromyalgia, and cardiovascular symptoms. Finally, socioeconomic consequences of workplace bullying may include absenteeism due to sick days and unemployment. Clinicians in both mental health and primary care settings need to be alert to the associations between bullying in the workplace and these potential negative consequences, as patients may not disclose workplace maltreatment due to embarrassment or fears of retribution.

Stress fracture, in its most inclusive description, includes both fatigue and insufficiency fracture. Fatigue fractures, sometimes equated with the term "stress fractures," are most common in runners and other athletes and typically occur in the lower extremities. These fractures are the result of abnormal, cyclical loading on normal bone leading to local cortical resorption and fracture. Insufficiency fractures are common in elderly populations, secondary to osteoporosis, and are typically located in and around the pelvis. They are a result of normal or traumatic loading on abnormal bone. Subchondral insufficiency fractures of the hip or knee may cause acute pain that may present in the emergency setting. Medial tibial stress syndrome is a type of stress injury of the tibia related to activity and is a clinical syndrome encompassing a range of injuries from stress edema to frank-displaced fracture. Atypical subtrochanteric femoral fracture associated with long-term bisphosphonate therapy is also a recently discovered entity that needs early recognition to prevent progression to a complete fracture. Imaging recommendations for evaluation of stress fractures include initial plain radiographs followed, if necessary, by magnetic resonance imaging (MRI), which is preferred over computed tomography (CT) and bone scintigraphy. Radiographs are the first-line modality and may reveal linear sclerosis and periosteal reaction prior to the development of a frank fracture. MRI is highly sensitive with findings ranging from periosteal edema to bone marrow and intracortical signal abnormality. Additionally, a brief description of relevant clinical management of stress fractures is included.

The mechanisms underlying chronic pain states, including osteoarthritis, differ from those underlying acute pain. In chronic pain states, central nervous system (CNS) factors often play a particularly prominent role. In many individuals with chronic pain, pain can occur with minimal or no evidence of ongoing nociceptive input. Medical subspecialties have applied a wide-range of labels to these pain conditions including fibromyalgia, irritable bowel syndrome and interstitial cystitis to name just a few. These same CNS processes can augment or magnify pain when there is ongoing nociceptive input, as in conditions such as osteoarthritis or autoimmune disorders. The hallmark of these 'centrally driven' pain conditions is a diffuse hyperalgesic state identifiable though the use of experimental sensory testing, that has been corroborated by functional neuroimaging. Characteristic symptoms of these central pain conditions include multifocal pain, fatigue, poor sleep, memory complaints and frequent co-morbid mood and anxiety disorders. In contrast to acute and peripheral pain states that are responsive to non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, central pain conditions respond best to CNS neuromodulating agents, such as serotonin-norepinephrine reuptake inhibitors (SNRIs) and anticonvulsants. While osteoarthritis is generally considered a peripherally mediated pain state, a subset of these patients also manifests centrally driven pain characteristics. Thus, osteoarthritis can also be thought of as a "mixed" pain state and this requires a more tailored approach to treatment.
