Cancer Pain Emergencies: Is There a Role for Radiation Therapy?

Emergent cancer pain is a difficult entity to manage. Radiation therapy potentially may be used for its treatment. Several key issues must be addressed in patients with emergent cancer pain before initiating radiation. These issues include whether the necessary diagnostic information is available, whether the tumor will respond rapidly to radiation, and whether there are additional patient factors that will affect treatment. If these questions have been addressed, it is more likely that a successful outcome will be obtained if radiation therapy is used for the management of emergent cancer pain.     

Bilateral Open Thoracic Cordotomy for Refractory Cancer Pain: A Neglected Technique?

At least 10% of patients with cancer have pain that is refractory to systemic analgesics. For most of these patients, interventional techniques may be of benefit but are often not considered or are difficult to access. Of these techniques, spinal analgesia is most commonly used in Australia and the United Kingdom, and neurosurgical procedures, such as open cordotomy with sectioning of the spinothalamic tract, are rarely used. We describe a case illustrating the successful use of bilateral open thoracic cordotomy in a patient with refractory mixed nociceptive and neuropathic pain secondary to a lumbosacral tumor. We discuss the various interventional options and review the recent literature regarding the use of both percutaneous and open cordotomy for cancer pain.     

Sex Differences in Pain Intensity in Adolescents Suffering From Cancer: Differences in Pain Memories?

Although sex differences have been investigated in chronic pain populations, little is known about sex differences in the pain experience of paediatric oncology patients and also whether their parents rate the pain experience differently for boys and girls. The aim of the present study was to determine if (1) boys and girls with cancer differ in current perception and past recollection of cancer-related pain and (2) if adolescents' and parents' pain ratings differ in relation to the sex of the adolescent. One hundred twelve adolescents with malignant diagnoses (12 to 18 years) and their parents participated in the study. Girls reported higher pain intensity within the last 7 days and 4 weeks despite similar diagnosis, physical status, duration of diagnoses, and main pain causes. When asked for pain intensity that dated back in time, parent and adolescent ratings diverged, with a trend for parents to reporting higher pain intensity in boys and lower pain intensity in girls, particularly for pain in the preceding 7 days. The present study provides preliminary evidence for sex differences in the recalled pain experience of adolescents with malignant diagnoses. Although boys and girls experience present pain similarly and hence should be treated similarly, girls recall higher pain intensity than boys. Future studies should address whether negative memories in girls play a significant role and may have an impact on girls' well-being and pain-related distress. Additionally, psychosocial factors such as gender role expectations may need to be investigated. Parental variables and their impact on parents' pain ratings, especially for ratings of precedent pain, warrants further investigation.PerspectiveGirls with malignant diagnoses differ from boys in their recalled pain intensity ratings, with girls reporting higher pain intensity. Additional pain management strategies referring to the memory of pain may need to be implemented.     

Buccal spray insulin (Oralgen) for type 2 diabetes: what evidence?

INTRODUCTION: The achievement of a good glycemic control and, in particular, the management of postprandial hyperglycemia represent the most significant treatment target for the management of diabetes. Multiple daily insulin injections are often still required to gain the treatment goals. Since the noncompliance with injected insulin therapy causes a slowdown in the process of glycemic compensation, novel non-injectable insulin formulations have been developed. Oral spray insulin (Oralgen) is a tasteless liquid formulation that provides insulin absorption via buccal mucosa. AREAS COVERED: To elucidate the current status of Oralgen in type 2 diabetes patients, studies of pharmacodynamic and pharmacokinetic and clinical trials are reviewed. EXPERT OPINION: The 'psychological insulin resistance,' represented by the reluctance of both patients and health-care professionals to initiate insulin therapy, could be won by alternative routes of insulin administration, improving patients' compliance. In particular, Oralgen seems to be suitable to manage the postprandial hyperglycemia without hypoglycemic risk, although no comparative studies with rapid-acting insulin analogs and no randomized controlled trials in large cohort subjects with type 2 diabetes are available to date.     

Pain Management Practices for Lumbar Punctures: Are We Consistent?

In most pediatric oncology centers across Canada, it is now standard practice for children to be sedated for lumbar punctures (LPs). Although the use of sedation for LPs is well established in the pediatric oncology population, its use in other hospital units is not well documented. A patient record audit was completed to understand the types of pain management strategies used for LPs performed throughout a pediatric hospital. Fifty-nine patients aged between 3 days and 17 years underwent a total of 67 LPs. Pain management strategies varied among the different patient service units. Oncology patients were consistently sedated for an LP, whereas patients in the emergency department were less likely to be given any type of sedation. Recommendations are aimed at providing consistent best practice pain management for LPs throughout the hospital.
