ABSTRACT: The professor's education posture (PEP) is a clearly indicator of the teaching practice that he or she realizes. Our objective was to estimate the presence of the PEP on medic groups with teaching formation: participative, traditional and without formation.
AN instrument was constructed and validated to estimate the presence of the PEP on three medic groups that work in two different medic units of high specialty in the north zone of Mexico City.
The instrument was applied in the evaluation of the PEP to 86 physicians, it was observed significant statistical differences in the development of the physicians that had realized a methodology qualify in teaching with a participative focus.
It is observed the development of an PEP in the physicians that have a teaching formation under a participative focus versus other physicians that had not the same teaching formation.

ABSTRACT: To build, validate and apply an instrument to evaluate the clinical aptitude in intraepitelial cervical neoplasia (ICN) in residents.
The instrument included four clinical real cases, validated by experts and included 106 items using true, false and don't know answers. A pilot test and the 21 Kuder-Richardson formula were used to estimate consistency. It was applied to residents, in an observational, transversal, comparative and open study, including 11 second year residents, 13 third year residents and 12 fourth year residents.
Consistency of 0.88 was obtained; 22% were located in the middle level, 39% were located in the low level and 39% in the very low level. There were no residents in the high or very high level or by chance answer level. The Kruskal-Wallis test showed significant differences among the three groups and with the U test of Mann Whitney there were no differences between groups.
The year of residence did not show differences in the development of clinical aptitude in ICN. Most of the residents were located in the inferior level of clinical aptitude. This study makes evident the need to reframe our educative processes in a qualitative different manner.

ABSTRACT: To determine the type and the frequency of diabetic neuropathy, diagnosed by electroneuromyography, in patients with type 2 diabetes mellitus, and the correlation between the neuropathy diagnosis and clinical symptoms.
Design: Cross-sectional descriptive and correlative of patients with diagnosis of type 2 diabetes mellitus, sent for electroneuromyography study in 2000. Study place: Laboratory of electrodiagnosis of the Unidad de Medicina Física y Rehabilitación Región Norte. Measuring: Electroneuromyography was performed, and the type and frequency of the diabetic neuropathy, as well as the presence of clinical systematization, according to the initial diagnosis, were assessed. Furthermore, sex, occupation, and medical unit of reference were identified. Analysis: Measures of central tendency and dispersion, as well as association by means of quadruple correlation ratio were considered.
219 electrodiagnostic studies were carried out in patients with type 2 diabetes mellitus, of which 152 were males. The age average was of 54.3 +/- 8.9 years old. The prevailing occupation was that of housewives with 128. The references of the Hospital General de Zona 24 were 39; those of Unidad de Medicina Física y Rehabilitación Región Norte were 32, and those of the Hospital General de Zona 98 were 28. There was a presence of clinical systematization in 186 (84.9%) patients. The electroneuromyography diagnosed diabetic neuropathy in 174 patients, of which 89 correspond to neuropathy due to segmental demyelination, and 85 to mixed neuropathy; in 21 patients, the electroneuromyography was normal. Of the 186 patients with clinical systematization, the electroneuromyography was positive in 170, with r = 0.70.
The prevalence of diabetic neuropathy in patients with type 2 diabetes mellitus is of 80%, the type of variety is of segmental demyelination in 51% and of mixed type in 49%. There is a high correlation between the clinical diagnosis of diabetic neuropathy and the confirmation by electroneuromyography.

ABSTRACT: To develop and validate an instrument to measure users' satisfaction of rehabilitation services.
Literature review to identify main construct domains, elaboration of items, pilot testing to reduce the number of items and redefinition of the questionnaire. The face and content validity were established by rehabilitation specialists. The questionnaire was applied to 85 users of rehabilitation services. The analysis was performed using a principal component factor analysis followed by a varimax rotation, then, the Scree test was used to select significant components and to estimate reliability and validity of the instrument, also Cronbach's alpha coefficient and the split-half test were ascertained.
The final version of the questionnaire consisted of 24 questions. Eighty-five patients answered the questionnaire that was completed in ten minutes on average. The principal components factor analysis and the Scree test detected 8 significant components. Internal consistency of the instrument had a coefficient Cronbach's alpha of 0.80 which was considered as acceptable, and the reliability, by means of the split-half test showed an alpha of 0.72 and 0.69 respectively.
The instrument to evaluate user's satisfaction of rehabilitation services showed to be valid and reliable.

ABSTRACT: To build, validate and apply an instrument to evaluate the clinical aptitudes of the emergency medicine residents of different degrees in the management of traumatic diseases at six different treatment locations in Mexico City.
This was a comparative cross-sectional study that evaluates the clinical aptitudes in the management of patients with traumatic injuries by residents specializing in emergency medicine at six different locations in Mexico City. The instrument was based on four clinical areas being validated by a consensus of experts in emergency medicine and educational investigation. A consistency of 0.94 within the pilot test was obtained. A non-parametric statistical analysis was carried out.
Included in the study were 141 residents from six locations and three with degrees of the specialty. A minimum scoring of 3 was obtained and a maximum of 119, with 25 possible answers expected by chance. Kruskal-Wallis test did not show significant differences among the six locations. To obtain comparison between levels, in only one location were significant differences found; 61 % of the residents demonstrated low aptitudes, 20.6 % reached intermediate level, 16.3 % showed a very low level, and only 0.7 % demonstrated a high level; no resident reached a very high level.
The educational process in the analyzed locations appears to not promote students generating their own criterion, which negatively affects the solution to routine problems.
