The institutional design of intra-party democracy through legal instruments: Turkish case

The importance of political parties for contemporary representative democracies is beyond dispute. Despite their significance for state-level democracy, political parties continue to be regarded as oligarchical and to be criticised because of their internal practices. For this reason, intra-party democracy (IPD) warrants in-depth analysis. This thesis investigates IPD in Turkey, primarily from the perspective of participatory democracy, with the purpose of suggesting reforms to the Turkish Political Parties Law (TPPL). Turkish political parties and Turkish party regulation provide an interesting case because there is a significant difference between mature democracies and Turkey regarding IPD regulation. IPD in established democracies has always been regarded as a private concern of parties and has been left unregulated. IPD in Turkey, by contrast, is provided for both by the constitution and the TPPL. Although IPD is a constitutional and legal requirement in Turkey, however, political parties in fact display a high level of non-democratic administration. The main reason is that the TPPL only pays lip service to the idea of IPD and requires no specific measures apart from establishing a party congress with a representative form of democracy. By establishing and holding party congresses, political parties are perceived as conforming to the requirements of IPD under the law. In addition, the contested nature of democracy as a concept has impeded the creation of efficacious legal principles. Thus, the existing party law fails to tackle the lack of IPD within political parties and, for this reason, is in need of reform. Furthermore, almost every Turkish party’s own constitution highlights the importance of IPD and promises IPD. However, these declared commitments to IPD in their constitutions alone, especially in countries where the democratic culture is weak, are unlikely to make much difference in practice. Accordingly, external regulation is necessary to ensure the protection of the rights and interests of the party members with regards to their participation in intra-party decision-making processes. Nevertheless, in spite of a general consensus in favour of reforming the TPPL, a lack of consensus exists as to what kind of reforms should be adopted. This thesis proposes that reforming the TPPL in line with an approach based on participatory democracy could provide better IPD within Turkish political parties, citing as evidence comparative case studies of the participatory practices for policy-making, leadership selection and candidate selection in mature democracies. This thesis also analyses membership registration and the effect of state funding on IPD, which are highly problematic in Turkey and represent impediments to the flourishing of IPD.

Étude d’évaluabilité et évaluation des processus et des effets d’un programme de prévention de l’usage de substances psychoactives lors de la transition primaire-secondaire

La mise en œuvre d’activités de prévention de la consommation de substances psychoactives (SPA) (tabac, alcool et cannabis) en milieu scolaire est une stratégie couramment utilisée pour rejoindre un grand nombre de jeunes. Ces activités s’inspirent, soit de programmes existant, soit d’innovations dictées par le contexte d’implantation ou l’existence de données de recherche. Dans un cas comme dans l’autre, l’évaluation de ces programmes représente la meilleure voie pour mesurer leur efficacité et/ou connaître comment ceux-ci sont implantés. C’est cet impératif qui a motivé une commission scolaire du Québec a recommandé l’évaluation de l’Intervention en Réseau (IR), un programme développé en vue de retarder l’âge d’initiation et de réduire la consommation problématique de SPA chez les élèves. Ce programme adopte une approche novatrice avec pour principal animateur un intervenant pivot (IP) qui assure le suivi des élèves de la 5e année du primaire jusqu’en 3e secondaire. Inspiré des modèles en prévention de la santé et de l’Approche École en santé (AES), le rôle de l’IP ici se démarque de ceux-ci. Certes, il est l’interface entre les différents acteurs impliqués et les élèves mais dans le cadre du programme IR, l’IP est intégré dans les écoles primaires et secondaires qu’il dessert. C’est cet intervenant qui assure la mobilisation des autres acteurs pour la mise en œuvre des activités. Cette thèse vise à rendre compte de ce processus d’évaluation ainsi que des résultats obtenus. L’approche d’évaluation en est une de type participatif et collaboratif avec des données quantitatives et qualitatives recueillies par le biais de questionnaires, d’entrevues, de groupes de discussion, d’un journal de bord et de notes de réunions. Les données ont été analysées dans le cadre de trois articles dont le premier concerne l’étude d’évaluabilité (ÉÉ) du programme. Les participants de cette ÉÉ sont des acteurs-clés du programme (N=13) rencontrés en entrevues. Une analyse documentaire (rapports et journal de bord) a également été effectuée. Cette ÉÉ a permis de clarifier les intentions des initiateurs du programme et les objectifs poursuivis par ces derniers. Elle a également permis de rendre la théorie du programme plus explicite et de développer le modèle logique, deux éléments qui ont facilité les opérations d’évaluation qui ont suivi. Le deuxième article porte sur l’évaluation des processus en utilisant la théorie de l’acteur-réseau (TAR) à travers ses quatre moments du processus de traduction des innovations (la problématisation, l’intéressement, l’enrôlement et la mobilisation des alliés), l’analyse des controverses et du rôle des acteurs humains et non-humains. Après l’analyse des données obtenues par entrevues auprès de 19 informateurs-clés, les résultats montrent que les phases d’implantation du programme passent effectivement par les quatre moments de la TAR, que la gestion des controverses par la négociation et le soutien était nécessaire pour la mobilisation de certains acteurs humains. Cette évaluation des processus a également permis de mettre en évidence le rôle des acteurs non-humains dans le processus d’implantation du programme. Le dernier article concerne une évaluation combinée des effets (volet quantitatif) et des processus (volet qualitatif) du programme. Pour le volet quantitatif, un devis quasi-expérimental a été adopté et les données ont été colligées de façon longitudinale par questionnaires auprès de 901 élèves de 5e et 6e année du primaire et leurs enseignants de 2010 à 2014. L’analyse des données ont montré que le programme n’a pas eu d’effets sur l’accessibilité et les risques perçus, l’usage problématique d’alcool et la polyconsommation (alcool et cannabis) chez les participants. Par contre, les résultats suggèrent que le programme pourrait favoriser la réduction du niveau de consommation et retarder l’âge d’initiation à l’alcool et au cannabis. Ils suggèrent également un effet potentiellement positif du programme sur l’intoxication à l’alcool chez les élèves. Quant au volet qualitatif, il a été réalisé à l’aide d’entrevues avec les intervenants (N=17), de groupes de discussion avec des élèves du secondaire (N=10) et d’une analyse documentaire. Les résultats montrent que le programme bénéficie d’un préjugé favorable de la part des différents acteurs ayant participé à l’évaluation et est bien acceptée par ces derniers. Cependant, le roulement fréquent de personnel et le grand nombre d’écoles à suivre peuvent constituer des obstacles à la bonne marche du programme. En revanche, le leadership et le soutien des directions d’écoles, la collaboration des enseignants, les qualités de l’IP et la flexibilité de la mise en œuvre sont identifiés comme des éléments ayant contribué au succès du programme. Les résultats et leur implication pour les programmes et l’évaluation sont discutés. Enfin, un plan de transfert des connaissances issues de la recherche évaluative est proposé.

Physical internet-enabled hyperconnected distribution assessment

L’Internet Physique (IP) est une initiative qui identifie plusieurs symptômes d’inefficacité et non-durabilité des systèmes logistiques et les traite en proposant un nouveau paradigme appelé logistique hyperconnectée. Semblable à l’Internet Digital, qui relie des milliers de réseaux d’ordinateurs personnels et locaux, IP permettra de relier les systèmes logistiques fragmentés actuels. Le but principal étant d’améliorer la performance des systèmes logistiques des points de vue économique, environnemental et social. Se concentrant spécifiquement sur les systèmes de distribution, cette thèse remet en question l’ordre de magnitude du gain de performances en exploitant la distribution hyperconnectée habilitée par IP. Elle concerne également la caractérisation de la planification de la distribution hyperconnectée. Pour répondre à la première question, une approche de la recherche exploratoire basée sur la modélisation de l’optimisation est appliquée, où les systèmes de distribution actuels et potentiels sont modélisés. Ensuite, un ensemble d’échantillons d’affaires réalistes sont créé, et leurs performances économique et environnementale sont évaluées en ciblant de multiples performances sociales. Un cadre conceptuel de planification, incluant la modélisation mathématique est proposé pour l’aide à la prise de décision dans des systèmes de distribution hyperconnectée. Partant des résultats obtenus par notre étude, nous avons démontré qu’un gain substantiel peut être obtenu en migrant vers la distribution hyperconnectée. Nous avons également démontré que l’ampleur du gain varie en fonction des caractéristiques des activités et des performances sociales ciblées. Puisque l’Internet physique est un sujet nouveau, le Chapitre 1 présente brièvement l’IP et hyper connectivité. Le Chapitre 2 discute les fondements, l’objectif et la méthodologie de la recherche. Les défis relevés au cours de cette recherche sont décrits et le type de contributions visés est mis en évidence. Le Chapitre 3 présente les modèles d’optimisation. Influencés par les caractéristiques des systèmes de distribution actuels et potentiels, trois modèles fondés sur le système de distribution sont développés. Chapitre 4 traite la caractérisation des échantillons d’affaires ainsi que la modélisation et le calibrage des paramètres employés dans les modèles. Les résultats de la recherche exploratoire sont présentés au Chapitre 5. Le Chapitre 6 décrit le cadre conceptuel de planification de la distribution hyperconnectée. Le chapitre 7 résume le contenu de la thèse et met en évidence les contributions principales. En outre, il identifie les limites de la recherche et les avenues potentielles de recherches futures.

Age and growth of Nassarius reticulatus in the Ria de Aveiro, north-west Portugal

Shell growth of the whelk Nassarius (¼Hinia) reticulatus was studied in the Ria de Aveiro (north-west Portugal) between 1995 and 1998. Temporal analysis of shell height frequency distributions demonstrated that growth occurs during the ¢rst ¢ve years of life, whelks attaining a size of 6.7^7.8 mm in the 1st year, 12.1^14.5 mm in the 2nd year, 18^19.5 mm in the 3rd year, 22.7^23.6 mm in the 4th year and by the 5th year males have achieved an average size of 25 mm whilst females have reached 27 mm. Age estimates from internal microscopic annual growth lines present in the shell lip suggest that large whelks may achieve a longevity of at least 11 years. External annual rings become less discernible as the whelks increase in size and estimates of their age based solely on ring counts can underestimate their age. In males sexual maturation is reached between the 3rd and 4th years whilst in females it is attained between the 4th and 5th years. Imposex was visible in 2 year old females and attained maximum development by the 5th year.

Anomalias dentárias em crianças com fissura palatina ou labial

As anomalias dentárias podem ocorrer como resultado de fatores genéticos e ambientais. Estas são geralmente causadas por defeitos em genes específicos, no entanto, eventos pré e pós-natais têm também sido implicados em diferentes tipos de anomalias dentárias. Quando comparados com a população geral, os indivíduos que apresentam fenda labial (FL) e fenda palatina (FP) demonstraram ter uma maior prevalência de anomalias dentárias, tais como variações de número, posição e tamanho, que na sua maioria se localizavam na área do defeito da fenda. Com este trabalho, pretendeu-se então, realizar uma revisão narrativa sobre as várias anomalias dentárias que podem estar associadas a FL ou FP, a sua prevalência e as opções terapêuticas recomendadas. Durante os meses de Dezembro de 2012 e Janeiro de 2013 foi realizada uma pesquisa bibliográfica na base de dados Pubmed atendendo às seguintes palavras chave “dental anomalies” AND “cleft lip and palate”; “oral health” AND “cleft lip and palate”. Na pesquisa empregaram-se os seguintes limites, artigos publicados nos últimos cinco anos, estudos em humanos, abstract disponível e artigos disponíveis em português, inglês e espanhol. Nesta pesquisa obteve-se um total de 50 artigos. Os artigos encontrados foram seleccionados primeiramente pelo título, seguidamente pela leitura cuidadosa dos abstracts e, finalmente, do artigo por inteiro, daí resultando um total de 17 artigos. Para o melhor entendimento do tema a ser desenvolvido, foram ainda considerados artigos de referência publicados em anos anteriores e livros de Odontopediatria e Genética Orofacial. As crianças com FL ou FP apresentam maior prevalência de anomalias dentárias de forma, número, posição, erupção e estrutura dentária, com localização privilegiada na área do defeito da fenda. Os pacientes portadores desta malformação congénita necessitam de intervenção precoce e acompanhamento continuado ao longo de toda a infância e adolescência, por uma equipa multidisciplinar que deverá incluir o pediatra, cirurgião maxilofacial, médico dentista, terapeuta da fala, psicólogo e cirurgião plástico.

Reproducing violence: Rihanna, Chris Brown and the aestheticisation of the Ciudad Juarez Femicides.

When Kate and Laura Mulleavy of Rodarte worked with MAC to create their Autumn/Winter 2010 makeup collection and based their ideas on the murdered women of Ciudad Juarez, there was a public and industry outcry which led to the withdrawal of cosmetics with names such as ‘Factory’ ‘Juarez’ and ‘Ghost Town’. Rodarte tapped into the borderland mythologies of Juarez and crated an illusory fantasy world which sought to simultaneously obliterate and venerate the dead women. One eyeshadow, ‘Bordertown’, appears to look like chunks of rotting flesh streaked with blood. The models for their catwalk show had hollow blackened eyes, green-white pallor and lips that had been bloodlessly ‘lip-erased’ with a product specifically designed for the purpose. In Spanish, maquillar is to make up, to assemble. The women in the factories are asked to repeat simple mechanical operations thousands of times a day to make up the products which will be sold by global corporations. At the same time their images are being assembled, made up and aestheticized to create a cosmetic erasure of the crimes which they are subject to. When two American women and a global company make profit from this dangerous cosmetic erasure in order to sell products, the borders between bodies, countries, art and crime become leaky through the act and the illusion of symbiosis between the women of Ciudad Juarez and the products they inspired is threatened by the haunting of exploitation. Since then, the situation has become more complex. Chris Brown got a neck tattoo, based, he says, on the promotional material produced by MAC for the Rodarte sisters campaign. The image, which is of a skull, bears a striking resemblance to the police photographs of his ex, and now current, girlfriend, superstar Rihanna. The controversy over gendered violence, race and exploitation, begun by Rodarte and MAC, came back, haunting, once again. This paper seeks to address these connections, and ask what happens when domestic violence collides with globalism, fashion and murder.

Three dimensional study to quantify the relationship between facial hard and soft tissue movement as a result of orthognathic surgery

Introduction Prediction of soft tissue changes following orthognathic surgery has been frequently attempted in the past decades. It has gradually progressed from the classic “cut and paste” of photographs to the computer assisted 2D surgical prediction planning; and finally, comprehensive 3D surgical planning was introduced to help surgeons and patients to decide on the magnitude and direction of surgical movements as well as the type of surgery to be considered for the correction of facial dysmorphology. A wealth of experience was gained and numerous published literature is available which has augmented the knowledge of facial soft tissue behaviour and helped to improve the ability to closely simulate facial changes following orthognathic surgery. This was particularly noticed following the introduction of the three dimensional imaging into the medical research and clinical applications. Several approaches have been considered to mathematically predict soft tissue changes in three dimensions, following orthognathic surgery. The most common are the Finite element model and Mass tensor Model. These were developed into software packages which are currently used in clinical practice. In general, these methods produce an acceptable level of prediction accuracy of soft tissue changes following orthognathic surgery. Studies, however, have shown a limited prediction accuracy at specific regions of the face, in particular the areas around the lips. Aims The aim of this project is to conduct a comprehensive assessment of hard and soft tissue changes following orthognathic surgery and introduce a new method for prediction of facial soft tissue changes.   Methodology The study was carried out on the pre- and post-operative CBCT images of 100 patients who received their orthognathic surgery treatment at Glasgow dental hospital and school, Glasgow, UK. Three groups of patients were included in the analysis; patients who underwent Le Fort I maxillary advancement surgery; bilateral sagittal split mandibular advancement surgery or bimaxillary advancement surgery. A generic facial mesh was used to standardise the information obtained from individual patient’s facial image and Principal component analysis (PCA) was applied to interpolate the correlations between the skeletal surgical displacement and the resultant soft tissue changes. The identified relationship between hard tissue and soft tissue was then applied on a new set of preoperative 3D facial images and the predicted results were compared to the actual surgical changes measured from their post-operative 3D facial images. A set of validation studies was conducted. To include: • Comparison between voxel based registration and surface registration to analyse changes following orthognathic surgery. The results showed there was no statistically significant difference between the two methods. Voxel based registration, however, showed more reliability as it preserved the link between the soft tissue and skeletal structures of the face during the image registration process. Accordingly, voxel based registration was the method of choice for superimposition of the pre- and post-operative images. The result of this study was published in a refereed journal. • Direct DICOM slice landmarking; a novel technique to quantify the direction and magnitude of skeletal surgical movements. This method represents a new approach to quantify maxillary and mandibular surgical displacement in three dimensions. The technique includes measuring the distance of corresponding landmarks digitized directly on DICOM image slices in relation to three dimensional reference planes. The accuracy of the measurements was assessed against a set of “gold standard” measurements extracted from simulated model surgery. The results confirmed the accuracy of the method within 0.34mm. Therefore, the method was applied in this study. The results of this validation were published in a peer refereed journal. • The use of a generic mesh to assess soft tissue changes using stereophotogrammetry. The generic facial mesh played a major role in the soft tissue dense correspondence analysis. The conformed generic mesh represented the geometrical information of the individual’s facial mesh on which it was conformed (elastically deformed). Therefore, the accuracy of generic mesh conformation is essential to guarantee an accurate replica of the individual facial characteristics. The results showed an acceptable overall mean error of the conformation of generic mesh 1 mm. The results of this study were accepted for publication in peer refereed scientific journal. Skeletal tissue analysis was performed using the validated “Direct DICOM slices landmarking method” while soft tissue analysis was performed using Dense correspondence analysis. The analysis of soft tissue was novel and produced a comprehensive description of facial changes in response to orthognathic surgery. The results were accepted for publication in a refereed scientific Journal. The main soft tissue changes associated with Le Fort I were advancement at the midface region combined with widening of the paranasal, upper lip and nostrils. Minor changes were noticed at the tip of the nose and oral commissures. The main soft tissue changes associated with mandibular advancement surgery were advancement and downward displacement of the chin and lower lip regions, limited widening of the lower lip and slight reversion of the lower lip vermilion combined with minimal backward displacement of the upper lip were recorded. Minimal changes were observed on the oral commissures. The main soft tissue changes associated with bimaxillary advancement surgery were generalized advancement of the middle and lower thirds of the face combined with widening of the paranasal, upper lip and nostrils regions. In Le Fort I cases, the correlation between the changes of the facial soft tissue and the skeletal surgical movements was assessed using PCA. A statistical method known as ’Leave one out cross validation’ was applied on the 30 cases which had Le Fort I osteotomy surgical procedure to effectively utilize the data for the prediction algorithm. The prediction accuracy of soft tissue changes showed a mean error ranging between (0.0006mm±0.582) at the nose region to (-0.0316mm±2.1996) at the various facial regions.

An auditory, acoustic, articulatory and sociophonetic study of Swedish Viby-i

The study investigates the acoustic, articulatory and sociophonetic properties of the Swedish /iː/ variant known as 'Viby-i' in 13 speakers of Central Swedish from Stockholm, Gothenburg, Varberg, Jönköping and Katrineholm. The vowel is described in terms of its auditory quality, its acoustic F1 and F2 values, and its tongue configuration. A brief, qualitative description of lip position is also included. Variation in /iː/ production is mapped against five sociolinguistic factors: city, dialectal region, metropolitan vs. urban location, sex and socioeconomic rating. Articulatory data is collected using ultrasound tongue imaging (UTI), for which the study proposes and evaluates a methodology. The study shows that Viby-i varies in auditory strength between speakers, and that strong instances of the vowel are associated with a high F1 and low F2, a trend which becomes more pronounced as the strength of Viby-i increases. The articulation of Viby-i is characterised by a lowered and backed tongue body, sometimes accompanied by a double-bunched tongue shape. The relationship between tongue position and acoustic results appears to be non-linear, suggesting either a measurement error or the influence of additional articulatory factors. Preliminary images of the lips show that Viby-i is produced with a spread but lax lip posture. The lip data also reveals parts of the tongue, which in many speakers appears to be extremely fronted and braced against the lower teeth, or sometimes protruded, when producing Viby-i. No sociophonetic difference is found between speakers from different cities or dialect regions. Metropolitan speakers are found to have an auditorily and acoustically stronger Viby-i than urban speakers, but this pattern is not matched in tongue backing or lowering. Overall the data shows a weak trend towards higher-class females having stronger Viby-i, but these results are tentative due to the limited size and stratification of the sample. Further research is needed to fully explore the sociophonetic properties of Viby-i.

Effect of temperature, food availability, and estradiol injection on gametogenesis and gender in the pearl oyster Pinctada margaritifera

The black-lip pearl oyster Pinctada margaritifera is a protandrous hermaphrodite species. Its economic value has led to the development of controlled hatchery reproduction techniques, although many aspects remain to be optimized. In order to understand reproductive mechanisms and their controlling factors, two independent experiments were designed to test hypotheses of gametogenesis and sex ratio control by environmental and hormonal factors. In one, pearl oysters were exposed under controlled conditions at different combinations of temperature (24 and 28°C) and food level (10,000 and 40,000 cells mL−1); whereas in the other, pearl oysters were conditioned under natural conditions into the lagoon and subjected to successive 17β-estradiol injections (100 μg per injection). Gametogenesis and sex ratio were assessed by histology for each treatment. In parallel, mRNA expressions of nine marker genes of the sexual pathway (pmarg-foxl2, pmarg-c43476, pmarg-c45042, pmarg-c19309, pmarg-c54338, pmarg-vit6, pmarg-zglp1, pmarg-dmrt, and pmarg-fem1-like) were investigated. Maximum maturation was observed in the treatment combining the highest temperature (28°C) and the highest microalgae concentration (40,000 cells mL−1), where the female sex tended to be maintained. Injection of 17β-estradiol induced a significant increase of undetermined stage proportion 2 weeks after the final injection. These results suggest that gametogenesis and gender in adult pearl oysters can be controlled by environmental factors and estrogens. While there were no significant effects on relative gene expression, the 3-gene-pair expression ratio model of the sexual pathway of P. margaritifera, suggest a probable dominance of genetic sex determinism without excluding a mixed sex determination mode (genetic + environmental)

Sialadenoma Papilliferum with Inverted Pattern in a Young Patient: A Case Report

BACKGROUND: Sialadenoma papilliferum (SP) is a rare, benign neoplasm of salivary gland origin which manifests as an exophytic papillary excrescence of the mucosa. Indeed, SP is both an exophytic proliferation of papillary stratified squamous epithelium above the mucosal surface and an endophytic salivary ductal proliferation beneath the mucosa. It arises predominantly in minor salivary glands and usually affects patients in the age range of 32-87 years, with reports in young patients being exceedingly rare.

Polynesian pearls

Black-lip pearl oyster culture in French Polynesia is still based on natural spat collection from wild stocks, but new developments in hatchery technology and selective breeding are bringing substantive change to the sector.

Evaluación de los cambios dentarios y su influencia en los tejidos blandos de pacientes tratados con sistema Damon Q y MBT

Se realizó una investigación con el objetivo de establecer los cambios dentarios y evaluar la influencia de estos en los tejidos blandos comparando pacientes tratados con sistema Damon Q (N=23) y MBT (N=16). Se seleccionó una muestra de estudio conformada por 39 individuos siendo 28 mujeres y 11 varones de edades comprendidas entre 11 y 26 años. Se registraron radiografías cefálicas laterales digitales tomadas antes y después de concluido el tratamiento. Las inclinaciones de los incisivos superiores e inferiores así como las alteraciones del perfil facial fueron medidas mediante el Software de análisis cefalométrico Nemotec Dental. Para determinar los cambios en los tejidos duros y blandos se aplicó la prueba T-Student verificándose diferencias estadísticamente significativas (p < 0,05) para los dos sistemas en las variables: ángulo incisivo maxilar, mandibular, posición del labio inferior según el plano estético de Ricketts y el de Burstone. La correlación existente entre los cambios en la inclinación de los incisivos y la posición labial, se evaluó mediante el coeficiente de relación de Pearson encontrando para el sistema Damon una correlación entre la posición del incisivo superior y la del labio superior e inferior, la posición del incisivo inferior tuvo una correlación moderada con el labio inferior, con la técnica MBT se encontró una relación moderada entre la posición del incisivo superior y el labio inferior. Se concluyó que existen cambios postratamiento en la posición de los incisivos, así como protrusión labial inferior hallando relación entre la inclinación vestibular de los incisivos y el movimiento de los labios en ambas técnicas

Molecular analysis of exons 8, 9 and 10 of the fibroblast growth factor receptor 2 (FGFR2) gene in two families with index cases of Apert Syndrome

Introduction: Apert syndrome (AS) is a craniosynostosis condition caused by mutations in the Fibroblast Growth Factor Receptor 2 (FGFR2) gene. Clinical features include cutaneous and osseous symmetric syndactily in hands and feet, with variable presentations in bones, brain, skin and other internal organs. Methods: Members of two families with an index case of Apert Syndrome were assessed to describe relevant clinical features and molecular analysis (sequencing and amplification) of exons 8, 9 and 10 of FGFR2 gen. Results: Family 1 consists of the mother, the index case and half -brother who has a cleft lip and palate. In this family we found a single FGFR2 mutation, S252W, in the sequence of exon 8. Although mutations were not found in the study of the patient affected with cleft lip and palate, it is known that these diseases share signaling pathways, allowing suspected alterations in shared genes. In the patient of family 2, we found a sequence variant T78.501A located near the splicing site, which could interfere in this process, and consequently with the protein function.

Clinical aspects associated with syndromic forms of Orofacial Clefts in a Colombian population

Objectives: To present descriptive epidemiology of Orofacial Clefts and to determine the association of syndromic forms with antenatal high-risk conditions, preterm birth, and comorbidities among nestedseries of cases. Methods: A study of nested-series of cases was conducted. Frequencies of cleft type, associated congenital anomalies, syndromic, non-syndromic and multiple malformation forms, and distribution of Orofacial Clefts according to sex and affected-side were determined. Odds ratios were calculated as measures of association between syndromic forms and antenatal high-risk conditions, preterm birth and comorbidities. A total of three hundred and eleven patients with Orofacial Clefts were assessed in a 12-month period. Results: The most frequent type of Orofacial Clefts was cleft lip and palate, this type of cleft was more frequent in males, whereas cleft palate occurred more often in females. The most common cases occurred as non-syndromic forms. Aarskog-Scott syndrome showed the highest frequency amongst syndromic forms. Hypertensive disorders in pregnancy, developmental dysplasia of the hip, central nervous diseases and respiratory failure showed significant statistical associations (p <0.05) with syndromic forms. Conclusions: These data provide an epidemiological reference of Orofacial Clefts in Colombia. Novel associations between syndromic forms and clinical variables are determined. In order to investigate causality relationships between these variables further studies must be carried out.
