Un repaso de la etnografía educativa en México hoy

Esta es una excelente oportunidad para repasar con ustedes lo que está sucediendo en México hoy en la investigación educativa, -particularmente en el acercamiento etnográfico- y así poder intercambiar puntos de vista sobre los problemas educativos de nuestros países y las formas de estudiarlos y analizarlos. Asimismo, nos permitirá reflexionar sobre sus alcances y limitaciones teórico-metodológicos, sobre el impacto que tiene en la esfera social y sobre los principales problemas y discusiones que debe enfrentar con el fin de avanzar en este campo de investigación. En mi exposición abordo lo que es la investigación etnográfica aplicada al campo educativo, presento un panorama sobre el desarrollo y las aplicaciones que ha tenido este enfoque en América Latina -y particularmente en México- y señalo algunas discusiones que se están llevando a cabo en la comunidad de etnógrafos.Este trabajo ha sido una exposición realizada en el IICE/UBA y FLACSO (Bs.

Myelofibrosis involving lymph node: a novel cytogenetic abnormality in a mimicker of mesenchymal neoplasm

A case of primary myelofibrosis involving lymph node and with a novel cytogenetic abnormality [del (18) (p11.2-3)] is reported. The abnormalities are identical among specimens from the lymph node, peripheral blood, and bone marrow that were analyzed years apart. Additionally, we show that the infiltrate by dysplastic megakaryocytes in the lymph node morphologically mimics a metastatic mesenchymal neoplasm, even when the clinical history myelofibrosis was known

Co-occurrence of outlet impingement syndrome of the shoulder and restricted range of motion in the thoracic spine - a prospective study with ultrasound-based motion analysis

<p>Abstract</p> <p>Background</p> <p>Shoulder complaints, and especially the outlet-impingement syndrome, are a common condition. Among other things, poor posture has been discussed as a cause. A correlation between impingement syndrome and restricted mobility of the thoracic spine (T) has been described earlier, but there has been no motion analysis of the thoracic spine to show these correlations. In the present prospective study, we intended to find out whether there is a significant difference in the thoracic sagittal range of motion (ROM) between patients with a shoulder outlet impingement syndrome and a group of patients who had no shoulder pathology. Secondly, we wanted to clarify whether Ott's sign correlates with ultrasound topometric measurements.</p> <p>Methods</p> <p>Two sex- and age-matched groups (2 × n = 39) underwent a clinical and an ultrasound topometric examination. The postures examined were sitting up straight, sitting in maximal flexion and sitting in maximal extension. The disabilities of the arm, shoulder and hand (DASH) score (obtained by means of a self-assessment questionnaire) and the Constant score were calculated. Lengthening and shortening of the dorsal projections of the spine in functional positions was measured by tape with Ott's sign.</p> <p>Results</p> <p>On examination of the thoracic kyphosis in the erect seated posture there were no significant differences between the two groups (p = 0.66). With ultrasound topometric measurement it was possible to show a significantly restricted segmental mobility of the thoracic spine in the study group compared with the control group (p = 0.01). An in-depth look at the mobility of the subsegments T1-4, T5-8 and T9-12 revealed that differences between the groups in the mobility in the lower two sections of the thoracic spine were significant (T5-8: p = 0.03; T9-12: p = 0.02). The study group had an average Constant score of 35.1 points and the control group, 85.5 (p < 0.001). On the DASH score the patient group reached 34.2 points and the control group, 1.4 (p < 0.001). The results of Ott's sign differed significantly between the two collectives (p = 0.0018), but showed a weak correlation with the ultrasound topometric measurements (study group flexion/extension: r = 0.36/0.43, control group flexion/extension: r = 0.29/0.26).</p> <p>Conclusion</p> <p>The mobility of the thoracic spine should receive more attention in the diagnosis and therapy of patients with shoulder outlet impingement syndrome.</p

Physical tests for shoulder impingements and local lesions of bursa, tendon or labrum that may accompany impingement

BackgroundImpingement is a common cause of shoulder pain. Impingement mechanisms may occur subacromially (under the coraco-acromial arch) or internally (within the shoulder joint), and a number of secondary pathologies may be associated. These include subacromial-subdeltoid bursitis (inflammation of the subacromial portion of the bursa, the subdeltoid portion, or both), tendinopathy or tears affecting the rotator cuff or the long head of biceps tendon, and glenoid labral damage. Accurate diagnosis based on physical tests would facilitate early optimisation of the clinical management approach. Most people with shoulder pain are diagnosed and managed in the primary care setting.ObjectivesTo evaluate the diagnostic accuracy of physical tests for shoulder impingements (subacromial or internal) or local lesions of bursa, rotator cuff or labrum that may accompany impingement, in people whose symptoms and/or history suggest any of these disorders.Search methodsWe searched electronic databases for primary studies in two stages. in the first stage, we searched MEDLINE, EMBASE, CINAHL, AMED and DARE (all from inception to November 2005). in the second stage, we searched MEDLINE, EMBASE and AMED(2005 to 15 February 2010). Searches were delimited to articles written in English.Selection criteriaWe considered for inclusion diagnostic test accuracy studies that directly compared the accuracy of one or more physical index tests for shoulder impingement against a reference test in any clinical setting. We considered diagnostic test accuracy studies with cross-sectional or cohort designs (retrospective or prospective), case-control studies and randomised controlled trials.Data collection and analysisTwo pairs of review authors independently performed study selection, assessed the study quality using QUADAS, and extracted data onto a purpose-designed form, noting patient characteristics (including care setting), study design, index tests and reference standard, and the diagnostic 2 x 2 table. We presented information on sensitivities and specificities with 95% confidence intervals (95% CI) for the index tests. Meta-analysis was not performed.Main resultsWe included 33 studies involving 4002 shoulders in 3852 patients. Although 28 studies were prospective, study quality was still generally poor. Mainly reflecting the use of surgery as a reference test in most studies, all but two studies were judged as not meeting the criteria for having a representative spectrum of patients. However, even these two studies only partly recruited from primary care.The target conditions assessed in the 33 studies were grouped under five main categories: subacromial or internal impingement, rotator cuff tendinopathy or tears, long head of biceps tendinopathy or tears, glenoid labral lesions and multiple undifferentiated target conditions. the majority of studies used arthroscopic surgery as the reference standard. Eight studies utilised reference standards which were potentially applicable to primary care (local anaesthesia, one study; ultrasound, three studies) or the hospital outpatient setting (magnetic resonance imaging, four studies). One study used a variety of reference standards, some applicable to primary care or the hospital outpatient setting. in two of these studies the reference standard used was acceptable for identifying the target condition, but in six it was only partially so. the studies evaluated numerous standard, modified, or combination index tests and 14 novel index tests. There were 170 target condition/index test combinations, but only six instances of any index test being performed and interpreted similarly in two studies. Only two studies of a modified empty can test for full thickness tear of the rotator cuff, and two studies of a modified anterior slide test for type II superior labrum anterior to posterior (SLAP) lesions, were clinically homogenous. Due to the limited number of studies, meta-analyses were considered inappropriate. Sensitivity and specificity estimates from each study are presented on forest plots for the 170 target condition/index test combinations grouped according to target condition.Authors' conclusionsThere is insufficient evidence upon which to base selection of physical tests for shoulder impingements, and local lesions of bursa, tendon or labrum that may accompany impingement, in primary care. the large body of literature revealed extreme diversity in the performance and interpretation of tests, which hinders synthesis of the evidence and/or clinical applicability.University of Teesside, Middlesbrough, UKDepartment of Health, UKUniv Teesside, Hlth & Social Care Inst, Middlesbrough TS1 3BA, Tees Valley, EnglandUniversidade Federal de São Paulo, Dept Orthopaed & Traumatol, São Paulo, BrazilUniv Birmingham, Birmingham, W Midlands, EnglandUniversidade Federal de São Paulo, Dept Orthopaed & Traumatol, São Paulo, BrazilWeb of Scienc
