Angina pectoris that is refractory to optimal medication and revascularization is becoming an increasingly common clinical problem. Recently the US Food and Drug Administration (FDA) approved transmyocardial laser revascularization (TMLR) for use in this group of patients and a large numbers of patients have already undergone this therapy. Unfortunately TMLR has is associated with an unacceptably high perioperative mortality (Cooley DA, Frazier OH, Kadipasaoglu KA, Lindenmeir MH, Pehlivanoglu S, KoIff JW, Wilansky S, Moore WH. ⋯ Am J Med Sci 1966;252:289-295). Here we describe a patient with end stage coronary artery disease and chronic refractory angina whose has been successfully treated with repeated unilateral left SGBs following multiple bypass operations, angioplasty procedures and laser therapy. This case report details his progress over a 34 month follow-up period.

The ultimate objective of our epidemiological research is to complete a longitudinal population-based study to document the prevalence and impact of acute, recurrent, and chronic pain in children and adolescents. As the first phase of our epidemiological research, we developed a comprehensive screening instrument for identifying children with acute, recurrent, and chronic pain, the Pain Experience Interview. We designed this interview to provide information about the lifetime and point prevalence of various pains, and also to provide information about the intensity, affect, duration, and frequency of children's pain. ⋯ These included four predictions about the common response patterns that we would expect to observe for all children based on our understanding of acute pain caused by trauma/disease, and six predictions about the distinct response patterns that we would expect to observe based on the known differences among children in their experiences of headache, acute treatment-related pain, recurrent pain, and chronic pain. All study predictions were confirmed, demonstrating that the Pain Experience Interview is a valid screening instrument for differentiating children with different types of pain problems. The interview can provide estimates for the lifetime and point prevalence of various pains in children, and data on the intensity, affect, duration, and frequency of their pain experiences.

This study examined the generalizability of the non-malignant pain patient profiles based on the Multidimensional Pain Inventory (MPI) to patients with cancer-related pain. Data were collected from 112 cancer patients. In total, 107/112 patients completed the MPI. ⋯ Given that 80% were classified as either Adaptive or Anomalous, these findings suggest that while the MPI-based profiles do apply, a two profile classification system may be more suitable for cancer patients than the usual three. In particular, the low proportion of patients classified as Interpersonally Distressed may reflect important differences in social support for cancer patients compared with non-cancer patients. Whereas the MPI-based profiles are consistent across non-malignant pain problems, it appears that the nature of cancer may affect the MPI-based profile classification system more than non-malignant pain problems do.

Little is known about the epidemiology of pain in children. We studied the prevalence of pain in Dutch children aged from 0 to 18 years in the open population, and the relationship with age, gender and pain parameters. A random sample of 1300 children aged 0-3 years was taken from the register of population in Rotterdam, The Netherlands. ⋯ The intensity of pain was higher in the case of chronic pain (P<0. 001) and multiple pains (P<0.001), and for chronic pain the intensity was higher for girls (P<0.001). These findings indicate that chronic pain is a common complaint in childhood and adolescence. In particular, the high prevalence of severe chronic pain and multiple pain in girls aged 12 years and over calls for follow-up investigations documenting the various bio-psycho-social factors related to this pain.

Phantom pain in subjects with an amputated limb is a well-known problem. However, estimates of the prevalence of phantom pain differ considerably in the literature. Various factors associated with phantom pain have been described including pain before the amputation, gender, dominance, and time elapsed since the amputation. ⋯ Phantom pain is a common problem in upper limb amputees that causes considerable suffering for the subjects involved. Only a minority of subjects are treated for phantom pain. Further research is needed to determine factors associated with phantom pain.
