This paper explores culturally-related concerns that arose during a multi-year study of obsessive-compulsive disorder (OCD) along the U.S.-Mexico border and describes adaptations made to better connect the research process to study participants. The purpose of this exploration is two-fold: (1) to offer suggestions for culturally sensitive borderland mental health research; and (2) to enhance dialog focused on culture, mental health research and the U.S.-Mexico border. Systematic coding of the written record of weekly research team meetings identified six recurring cultural concerns: emotionally charged and poorly understood terminology; differing meanings of ethnicity and acculturation; quality of life—regional variation and uncertainty; overlap of research and care; hopeful but hesitant; and fatalism. We conclude that diligence in the initial planning phase of a study is only part of the challenge in doing culturally sensitive research. Equally important is an ongoing process of evaluation to make explicit cultural concerns that arise during research, as well as a readiness to implement culturally sensitive research adaptations. 相似文献

During computed tomography (CT) pelvimetry of two pregnant women, bony abnormalities of the fetuses were noted on the scout images that were not confirmed at delivery. To explore the cause of these artifacts, specimen long bones were manipulated in various ways during CT scout imaging. Artifacts like those seen during in vivo imaging were found to be caused by motion of the object. The CT scout view is an example of an image produced by a digital system that uses a scanning beam. This type of digital system is being used for several types of body imaging including screening for scoliosis and chest radiography. Attention to motion artifacts should decrease diagnostic errors and aid further development of these systems. 相似文献

As a component of a series of studies of childhood diarrhoea in rural Nicaragua, lay knowledge regarding the condition and its appropriate management has been investigated through semistructured interviews with 70 mothers. These data have been combined with information from focus group discussions and observations from investigators who have been resident in the study area for many years. For any episode of childhood diarrhoea, the lay nosology influences the treatment path followed. Thus for some types of diarrhoea, treatment at a health centre or health post and the use of rehydration fluids is seen to be appropriate, while for other types the use of traditional healers or home-based treatment, often explicitly without the use of rehydration fluids, is applicable. The implications of lay nosological systems for the interpretation of epidemiological studies and for the implementation of health promotion programmes are discussed. 相似文献

Cerebral blood flow relationships associated with a difficult tone recognition task in trained normal volunteers 总被引:2,自引:2,他引:0

Tone recognition is partially subserved by neural activity in the right
frontal and primary auditory cortices. First we determined the brain areas
associated with tone perception and recognition. This study then examined
how regional cerebral blood flow (rCBF) in these and other brain regions
correlates with the behavioral characteristics of a difficult tone
recognition task. rCBF changes were assessed using H2(15)O positron
emission tomography. Subtraction procedures were used to localize
significant change regions and correlational analyses were applied to
determine how response times (RT) predicted rCBF patterns. Twelve trained
normal volunteers were studied in three conditions: REST, sensory motor
control (SMC) and decision (DEC). The SMC-REST contrast revealed bilateral
activation of primary auditory cortices, cerebellum and bilateral inferior
frontal gyri. DEC-SMC produced significant clusters in the right middle and
inferior frontal gyri, insula and claustrum; the anterior cingulate gyrus
and supplementary motor area; the left insula/claustrum; and the left
cerebellum. Correlational analyses, RT versus rCBF from DEC scans, showed a
positive correlation in right inferior and middle frontal cortex; rCBF in
bilateral auditory cortices and cerebellum exhibited significant negative
correlations with RT These changes suggest that neural activity in the
right frontal, superior temporal and cerebellar regions shifts back and
forth in magnitude depending on whether tone recognition RT is relatively
fast or slow, during a difficult, accurate assessment.

Summary Sixty five patients with various traumatic lesions of the fingers have been operated on under digital anaesthesia using 3 ml of 2% Mepivacaine injected into the flexor tendon sheath. The anaesthesia was adequate for surgery in all instances except in one patient. No complications were encountered with this technique. The authors studied the mechanism of action by dissecting a cadaveric hand after injecting a tracer (Methylene blue) in place of the local anaesthesia, suggesting, but not proving, that anaesthesia is achieved by blocking the nerve in the area of the injection.
Résumé Soixante-cinq patients, victimes de traumatismes divers des doigts, ont été opérés sous anesthésie locale, à travers la gaîne du tendon fléchisseur, par 3ml de Mapivacaïne à 2%. Sauf dans un cas, l'anesthésie a toujours permis d'effectuer l'intervention. Il n'y a pas eu de complications dues à cette technique. Les auteurs ont étudié le mécanisme d'action en disséquant la main d'un cadavre auquel avait été, au préalable, administré un marqueur (bleu de méthylène) comme s'il s'agissait d'un anesthésique local. On a pu en conclure que l'anesthésie était obtenue par le blocage du nerfprès du lieu d'injection.相似文献
