Motivating Medical Students To Learn Basic Science Concepts Using Chronic Myeloid Leukemia As An Integration Theme.

To report on the use of chronic myeloid leukemia as a theme of basic clinical integration for first year medical students to motivate and enable in-depth understanding of the basic sciences of the future physician. During the past thirteen years we have reviewed and updated the curriculum of the medical school of the Universidade Estadual de Campinas. The main objective of the new curriculum is to teach the students how to learn to learn. Since then, a case of chronic myeloid leukemia has been introduced to first year medical students and discussed in horizontal integration with all themes taught during a molecular and cell biology course. Cell structure and components, protein, chromosomes, gene organization, proliferation, cell cycle, apoptosis, signaling and so on are all themes approached during this course. At the end of every topic approached, the students prepare in advance the corresponding topic of clinical cases chosen randomly during the class, which are then presented by them. During the final class, a paper regarding mutations in the abl gene that cause resistance to tyrosine kinase inhibitors is discussed. After each class, three tests are solved in an interactive evaluation. The course has been successful since its beginning, 13 years ago. Great motivation of those who participated in the course was observed. There were less than 20% absences in the classes. At least three (and as many as nine) students every year were interested in starting research training in the field of hematology. At the end of each class, an interactive evaluation was performed and more than 70% of the answers were correct in each evaluation. Moreover, for the final evaluation, the students summarized, in a written report, the molecular and therapeutic basis of chronic myeloid leukemia, with scores ranging from 0 to 10. Considering all 13 years, a median of 78% of the class scored above 5 (min 74%-max 85%), and a median of 67% scored above 7. Chronic myeloid leukemia is an excellent example of a disease that can be used for clinical basic integration as this disorder involves well known protein, cytogenetic and cell function abnormalities, has well-defined diagnostic strategies and a target oriented therapy.

Variations on a theme: diversification of cuticular hydrocarbons in a clade of cactophilic Drosophila

Background: We characterized variation and chemical composition of epicuticular hydrocarbons (CHCs) in the seven species of the Drosophila buzzatii cluster with gas chromatography/mass spectrometry. Despite the critical role of CHCs in providing resistance to desiccation and involvement in communication, such as courtship behavior, mating, and aggregation, few studies have investigated how CHC profiles evolve within and between species in a phylogenetic context. We analyzed quantitative differences in CHC profiles in populations of the D. buzzatii species cluster in order to assess the concordance of CHC differentiation with species divergence. Results: Thirty-six CHC components were scored in single fly extracts with carbon chain lengths ranging from C(29) to C(39), including methyl-branched alkanes, n alkenes, and alkadienes. Multivariate analysis of variance revealed that CHC amounts were significantly different among all species and canonical discriminant function (CDF) analysis resolved all species into distinct, non-overlapping groups. Significant intraspecific variation was found in different populations of D. serido suggesting that this taxon is comprised of at least two species. We summarized CHC variation using CDF analysis and mapped the first five CHC canonical variates (CVs) onto an independently derived period (per) gene + chromosome inversion + mtDNA COI gene for each sex. We found that the COI sequences were not phylogenetically informative due to introgression between some species, so only per + inversion data were used. Positive phylogenetic signal was observed mainly for CV1 when parsimony methods and the test for serial independence (TFSI) were used. These results changed when no outgroup species were included in the analysis and phylogenetic signal was then observed for female CV3 and/or CV4 and male CV4 and CV5. Finally, removal of divergent populations of D. serido significantly increased the amount of phylogenetic signal as up to four out of five CVs then displayed positive phylogenetic signal. Conclusions: CHCs were conserved among species while quantitative differences in CHC profiles between populations and species were statistically significant. Most CHCs were species-, population-, and sex-specific. Mapping CHCs onto an independently derived phylogeny revealed that a significant portion of CHC variation was explained by species' systematic affinities indicating phylogenetic conservatism in the evolution of these hydrocarbon arrays, presumptive waterproofing compounds and courtship signals as in many other drosophilid species.

Biochemistry of the Envenomation Response-a Generator Theme for Interdisciplinary Integration

The understanding of complex physiological processes requires information from many different areas of knowledge. To meet this interdisciplinary scenario, the ability of integrating and articulating information is demanded. The difficulty of such approach arises because, more often than not, information is fragmented through under graduation education in Health Sciences. Shifting from a fragmentary and deep view of many topics to joining them horizontally in a global view is not a trivial task for teachers to implement. To attain that objective we proposed a course herein described Biochemistry of the envenomation response aimed at integrating previous contents of Health Sciences courses, following international recommendations of interdisciplinary model. The contents were organized by modules with increasing topic complexity. The full understanding of the envenoming pathophysiology of each module would be attained by the integration of knowledge from different disciplines. Active-learning strategy was employed focusing concept map drawing. Evaluation was obtained by a 30-item Likert-type survey answered by ninety students; 84% of the students considered that the number of relations that they were able to establish as seen by concept maps increased throughout the course. Similarly, 98% considered that both the theme and the strategy adopted in the course contributed to develop an interdisciplinary view.

Phonological development in relation to native language and literacy: Variations on a theme in six alphabetic orthographies

Phonological development was assessed in six alphabetic orthographies (English, French, Greek, Icelandic, Portuguese and Spanish) at the beginning and end of the first year of reading instruction. The aim was to explore contrasting theoretical views regarding: the question of the availability of phonology at the outset of learning to read (Study 1); the influence of orthographic depth on the pace of phonological development during the transition to literacy (Study 2); and the impact of literacy instruction (Study 3). Results from 242 children did not reveal a consistent sequence of development as performance varied according to task demands and language. Phonics instruction appeared more influential than orthographic depth in the emergence of an early meta-phonological capacity to manipulate phonemes, and preliminary indications were that cross-linguistic variation was associated with speech rhythm more than factors such as syllable complexity. The implications of the outcome for current models of phonological development are discussed.

Renewable energy systems the theme for the PACITA summer school on TA, Liège, Belgium, 25 28 June 2012

The summer school “Renewable Energy Systems: Role and Use of Parliamentary Technology Assessment” was the first European Summer School with a pure focus on technology assessment. The aim of the three-day long summer school of the European project Parliaments and Civil Society in Technology Assessment (PACITA) was to create awareness of the potential of technology groups in Europe. Therefore, the summer school involved keynotes, practical exercises, mutual reflection, cutting edge training and networking to deal with the theme of renewable energy systems out of the perspective of Technology Assessment (TA), to meet transition objectives or to critically assess energy technologies.

Oculopalatal Tremor : Variations on a theme by Guillain and Mollaret

Le trémor oculo-palatin (TOP) est une complication tardive et rare faisant suite à une lésion au niveau du tronc cérébral. Il est caractérisé par des contractions involontaires du voile du palais (pratiquement toujours asymptomatique), synchronisées avec un nystagmus pendulaire à environ 2 Hz (toujours symptomatique, se manifestant par des oscillopsies). Un hypersignal du noyau de l'olive inférieure (HNOI) est visible en IRM ; l'HNOI persiste au fil des ans. Notre objectif était de mieux définir le profil clinique des patients avec un TOP. Pour ceci nous avons effectué une étude rétrospective de 8 patients présentant un TOP et avons compilé ces résultats avec les 82 cas que nous avons retrouvé dans la littérature mondiale (revue PubMed). L'âge moyen était de 54 ans, avec une prédominance masculine. L'étiologie la plus fréquente était une lésion vasculaire du tronc cérébral (80%). Un nystagmus pendulaire principalement vertical a été retrouvé dans 90% des cas. Un nystagmus dissocié était principalement associé à une HNOI controlatérale et unilatérale sur l'IRM. Un nystagmus bilatéral et symétrique résultait d'une HNOI bilatérale dans la majorité des cas. Trois singularités ont été retrouvées parmi nos 8 patients : 1) une HNOI ipsilatérale à un nystagmus dissocié ; 2) la persistance du nystagmus en cas de disparition de l'HNOI ; 3) la découverte d'un micronystagmus asymptomatique. Le profil clinique du TOP reste assez stéréotypé, malgré quelques variations possibles (cf nos trois singularités). Les oscillopsies sont parfois handicapantes et il n'existe pas à ce jour de traitement spécifique du TOP.

Oculopalatal tremor: variations on a theme by Guillain and Mollaret.

BACKGROUND: Oculopalatal tremor (OPT) is a delayed complication of a brainstem lesion, characterized by involuntary contractions of the soft palate associated with a synchronized ocular pendular nystagmus. MRI reveals inferior olivary nucleus hypersignal/hypertrophy (IONH). Our objective was to refine the clinical profile of patients with OPT and to report a few oddities in both presentation and evolution. METHODS: We performed a retrospective study of patients diagnosed with OPT and a literature search. RESULTS: From our database, we retrieved 5 men and 3 women with a diagnosis of OPT. Eighty-two patients with OPT were retrieved from the literature and were compiled with our series. The average age was 54 years and there was a male predominance. Brainstem vascular lesion was the most common etiology (80%). Prominent vertical pendular nystagmus was found in 90%. Dissociated nystagmus was mostly associated to unilateral contralateral IONH on MRI, while bilateral symmetrical nystagmus was due to a bilateral IONH in the majority of cases. Three oddities were found amongst our 8 patients: prominent nystagmus ipsilateral to IONH; disappearance of IONH on MRI despite persisting nystagmus, and asymptomatic OPT. CONCLUSION: The clinical profile of OPT is rather stereotyped. Rarely do patients deviate from the classical description of OPT.
