Coping, pain severity, interference, and disability: the potential mediating and moderating roles of race and education.

Researchers have demonstrated that certain types of pain coping are correlated with less pain severity and disability and that there are differences between Caucasians and African-American pain patients in their use of specific coping strategies. However, the extent to which racial group differences exist in the associations between pain coping strategies and pain severity, interference, and disability is unclear. Furthermore, the role of education in these associations is uncertain. We recruited a diverse community sample of individuals with chronic pain and their spouses to examine this issue (N = 105). Participants completed the Coping Strategies Questionnaire, Multidimensional Pain Inventory, and Sickness Impact Profile. Results showed that African-American participants reported significantly more pain severity, interference, and disability and reported using diverting attention and prayer and hoping pain-coping strategies significantly more often than Caucasian participants; however, only the racial group difference in prayer and hoping remained when controlling for education. We also examined whether race and education interacted with coping strategies in relating to pain and disability. Significant three-way interactions were found for physical and psychosocial disability, suggesting that educational level should be included in analyses exploring racial group differences. The results suggest the need for pain treatments that take into account the educational and cultural context of pain. PERSPECTIVE: This article demonstrates that demographic variables such as race and education should be considered together when evaluating the effectiveness of coping with pain. The findings have the potential to enhance research and clinical practice with diverse groups.     

Value of MR imaging in the evaluation of chronic infiltrative lung diseases: comparison with CT.

The value of MR imaging was compared with that of high-resolution CT in assessing chronic infiltrative lung disease in 25 patients. The cases included nine patients with usual interstitial pneumonia, six with sarcoidosis, four with hypersensitivity pneumonitis, and six with miscellaneous conditions. The diagnosis was proved by biopsy (n = 17) or by means of clinical, laboratory, and radiologic criteria (n = 8). All patients had 1.5-T MR imaging and CT of the chest. Cardiac-gated T1-, proton density-, and T2-weighted spin-echo sequences were obtained. Initially, the MR images were assessed independently; later they were compared directly with the corresponding CT scans. In six patients, MR images and CT scans were obtained before open lung biopsy, and the images and scans were assessed prospectively. CT was superior to MR imaging in the anatomic assessment of the lung parenchyma and in showing fibrosis. However, areas of air-space opacification (ground-glass opacities) were seen as well on MR as on high-resolution CT. In the six patients who had open lung biopsy, areas of air-space opacification seen on MR and on CT corresponded to areas of active alveolitis or air-space infiltrates pathologically. Follow-up in six patients showed equal degrees of change in the air-space opacification over time on MR and CT. We conclude that, although MR imaging is inferior to high-resolution CT in the assessment of chronic infiltrative lung diseases, it may play a role in the assessment and follow-up of patients with air-space opacification.     

Terrorist bombing

Bombings and explosion incidents directed against innocent civilians are the primary instrument of global terror. In the present review we highlight the major observations and lessons learned from these events. Five mechanisms of blast injury are outlined and the different type of injury that they cause is described. Indeed, the consequences of terror bombings differ from those of non-terrorism trauma in severity and complexity of injury, and constitute a new class of casualties that differ from those of conventional trauma. The clinical implications of terror bombing, in treatment dilemmas in the multidimensional injury, ancillary evaluation and handling of terror bombing mass casualty event are highlighted. All this leads to the conclusion that thorough medical preparedness to cope with this new epidemic is required, and that understanding of detonation and blast dynamics and how they correlate with the injury patterns is pivotal for revision of current mass casualty protocols.     

Traumatic or septic aortic regurgitation: diagnosis by oesophageal echocardiography

Severe aortic regurgitation was discovered in a young man 21 days after blunt chest trauma and after a prolonged febrile state with positive blood cultures. Using transoesophageal echocardiography (TEE), it was possible to make the differential diagnosis between traumatic rupture and endocarditis as the cause of valvular insufficiency. The use of TEE in the initial evaluation of severe thoracic trauma with an unclear clinical picture is recommended. This method is easy to use at the bedside and gives precise information on the aortic valve and the ascending aorta.     

Lack of acute d-amphetamine effects on thyrotropin release

Case reports have suggested that amphetamine abuse causes excessive secretion of thyrotropin (TSH) and thyroxine (T4). Such an amphetamine-induced effect might be noradrenergic-mediated in the hypothalamus. The current controlled study examined oral d-amphetamine effects on the hypothalamic-pituitary-thyroid axis in normal humans. No acute effects were seen on TSH, T3 or T4 levels. d-Amphetamine elevated cortisol levels at 180 min, as previously reported.     

Clinical and histological patterns of dermatofibromas of the nail apparatus

True fibromas develop as painless slow-growing nodular tumours. They may appear in any portion of the nail apparatus. The clinical features vary according to their anatomical site. In contrast, the histological features, consisting of a dermal hypocellular reticular nodule with ill-defined demarcation, were similar in all our patients, and factor XIIIa was negative.
