Pensamiento & Gestión , 2008,
Abstract: Este trabajo de investigación intenta determinar un perfil gerencial para las instituciones de salud de Barranquilla, basado en el consenso de un panel de expertos de las ciudades de Bogotá, Medellín y Barranquilla. Para ello se definen las competencias del hacer, ser y del conocimiento que componen todo perfil, apoyadas en el Instituto Latinoamericano para el Liderazgo y autoridades académicas en el tema de las competencias y en los estudios realizados por Renée Bédard en los Modos de ser y su aplicación en la administración. Para la determinación del perfil gerencial se aplicaron algunos de los Métodos de Michel Godet de la Caja de herramientas de la prospectiva estratégica -Laboratoire d'Investigation Prospective et Stratégique CNAM, Instituto Europeo de Prospectiva y Estrategia-. El resultado es un perfil gerencial conformado por 50% de las competencias que se considera están relacionadas con el ser, el 30% con la competencia del conocer y el 20% con la competencia del hacer. Además se establece que cada una de esas competencias están estrechamente interrelacionadas entre sí y representan un verdadero desafío para quienes quieran ocupar u ocupan posiciones gerenciales para el logro exitoso de su gestión.

Abstract: secondary cementum is deposited in a root apical third throughout the lifespan of a tooth to compensate occlusal erosion, keeping dental pieces in occlusion contact. pearls are more difficult to spot, found by x-rays or after extraction. their ovoid or spherical aspect is well outlined, hard to touch, and located in different thirds of the root. our objective was to compare physical and radiological dental normal roots characteristics with those presenting this type of formations that alter radicular anatomy. we used 20 normal roots and 20 pearl shapes. variables compared: age, sex, previous general pathologies and periodontals; extracted tooth type, dental arch location, extraction cause, consistency characteristics, color, aspect and texture of all roots and pearls. radiological image was crucial for incorporation of teeth with cementum excess. proportions between normal pieces and pearls were calculated with fisher's exact test, with 5% significance level. average age was 61years (16-79), and male proportion was 42.5% and 57.5% female. general pathology presented 37.5 % and periodontal 55%, more extracted teeth were right side upper premolars 15%. caries were extraction chief motive 72.5%. roots were of hard consistency and smooth texture in both groups; nacreous aspect was 65%, clear colors 75%. pearl consistency was hard in all of them; white color 60% and root similar color 40%; nacreous aspect 75% and smooth texture 90%. in radiographs was observed that cementum did not differ from dentine in 85% of pearls and in 60% of normal roots (p=0.004). adults can develop cementum anomalies located in another apex sector although the root physical characteristics are considered inside normal parameters.

Abstract: El cemento secundario del ápice radicular se deposita en forma lenta y continua durante toda la vida útil del diente, siendo su función compensar el desgaste producido por la masticación. En raras ocasiones podemos hallar en la raíz dental, a posteriori de una extracción dentaria, excesos de cementos redondeados u ovalados, bien delimitados y duros al tacto, ubicados en un sector radicular diferente al ápice. Nuestro objetivo fue comparar las características físicas y radiológicas de raíces dentales normales con aquéllas que presentan este tipo de formaciones que alteran la anatomía radicular. Fueron incluidos 20 dientes adultos con raíces normales y 20 con raíces donde se visualizaron estos depósitos. Las variables investigadas fueron edad, sexo, patologías generales y periodontales previas, tipo de diente extraído, ubicación en el arco dental, motivo de extracción, características de consistencia, color, aspecto y textura de todas las raíces. La imagen radiológica fue crucial para la inclusión de dientes con exceso de cemento. Se recolectó un total de 40 dientes adultos, cuya edad promedio fue de 61a os (16-79), 42.5% masculinos y 57.5% femeninos. Patología general presentó el 37.5% y periodontal el 55%, los dientes mas extraídos fueron premolares superiores del lado derecho 15%. La caries fue causa principal de extracción 72.5%. En ambos grupos las raíces fueron de consistencia dura y textura lisa. El aspecto nacarado fue de 70% y 60%, los colores claros 45% y 75%, respectivamente. En las radiografías se observó que el cemento no se diferenció de la dentina en el 40% y 85% de cada grupo (p=0.004). Los adultos pueden desarrollar anomalías de cemento ubicadas en otro sector del ápice si bien las características físicas de la raíz se consideran dentro de parámetros normales.

Abstract: neural tube defects are congenital malformations that occur during initial fetal development, leading to anencephaly and spina bifida; folic acid deficiency is the most important risk factor identified to date. brazil has one of the world's highest neural tube defect rates. food consumption surveys among pregnant brazilian women showed a high rate of inadequate folic acid intake (< 0.6mg/day). in 2004, the national health surveillance agency (anvisa) mandated the fortification of corn meal and wheat flour with folic acid (0.15mg/100g). the national family budget survey estimated the average amount of bread/flour products available in households as 106.1g/day (contributing with 0.16mg folic acid/day). however, while in the south of the country the supply was 144g/day, in the north and central west it barely reached 70g/day. folic acid food fortification is mandatory in some 40 countries, but only four have assessed this strategy. the existing studies have all shown a significant impact, ranging from 19 to 78%. folic acid fortification is an undeniably important intervention for primary prevention, and neural tube defects can now be considered a preventable epidemic.

Abstract: iron deficiency anemia (ida) is the most prevalent micronutrient deficiency in the world. in school age children, ida is particularly deleterious: anemic children are sleepy and pay less attention. as a consequence, anemia can lead to high absenteeism and lower school performance. a cross-sectional survey was conducted in a representative sample of 424 randomly selected first graders (ages 6 to 11 years) from public schools located in the northern public health region of brasília. the study objectives were to: (a) determine the prevalence of anemia; (b) compare the results obtained in 2004 to those of a similar survey conducted in the same area in 1998. hemoglobin (hb) was determined in finger-prick blood samples using hemocue?. two cut-off points were used to classify anemia, both established by the who: hb<11.5g/dl and hb<12.0g/dl. the height/age, weight/age and weight/height indicators below -2.0 standard deviations from the nchs reference were used to indicate growth retardation. prevalence of anemia was 12.5% and 11.9% (hb<11.5g/dl) and 26.9% and 21.5% (hb<12.0g/dl) in 2004 and 1998 respectively. the prevalence of anemia increased between the surveys, but the difference was not significant. there was no statistically significant association between growth retardation and anemia. a high prevalence of anemia was observed, which justifies the implementation of public policies to fight the problem, such as the fortification of wheat and corn flours with iron, mandatory since 2004.

Abstract: causes of poverty, hunger and malnutrition are multiple and complex. current and past discussions promote the idea of an income able to guarantee the human right to adequate food, which is fundamental to life. local experiences in brazil have supported the creation of national conditional cash transfer programs. the objective of the study was to perform a qualitative analysis about the perception and practice of the stakeholders directly or indirectly involved in the programs bolsa escola, bolsa alimenta??o and cart?o alimenta??o in the federal and state levels. program managers and key informants were interviewed, and minutes of social councils meetings and speeches of congressmen were analyzed. programs objectives indicate an apparent universality; however, their essence revealed fragmentation and selection among the already targeted beneficiaries. considering their importance in the reduction of poverty these programs should be articulated and interdisciplinary, integrating several interventions in order to improve the quality of life of their beneficiaries. isolated, they are not capable of finding solutions for poverty and hunger.

Abstract: the dentin-pulp complex shares the odontoblast, whose body is located in the external part of the dental pulp. the odontoblast process emerges from the apical pole and penetrates the dentinal canaliculus through the dentine producing multiple collaterals along the way. descriibing the process was an arduous task for researchers, who combined histological techniques to preserve it in the interior of the canaliculi using transmission electron microscopy or scanning to visualize it. in a previous work we observed both tissues joined by the odontoblasts and the stained processes. the objective now was to micrometrically measure the length of the processes and canaliculi to verify if they are similar in the crown and in the root. thirty healthy teeth were used, extracted for orthodontic reasons, from individuals of both sexes whose ages ranged from 6 to 18. the dental pulp was uncovered and attached, and they were divided in equal parts. the halves without pulp were prepared with the erosion technique. the halves that kept the pulp were demineralized with type ii collagenase and stained with the schmorl technique. with an optical microscope and a calibrated grid with a micrometric objective the width of the histological fields was first measured and then the length of the dentinal processes and canaliculi. the results were analyzed with chi2 test, student t and fischer's exact test with a 5% significance level. we observed that the width of the stained histological fields had a 92 % retraction compared to the same field in the erosion and that the length of the canaliculi was always greater than the length of the processes, although four coincidences in length were found in the crown and one in the root. these results suggest that the length of the process is still a controversial topic. professional precaution in odontological treatments is the safest prevention against injuries.

Abstract: the embryological, structural and functional unit of the dentine-pulp complex shares the odontoblast, located in the border of the dentine pulp, with basal nuclei and organelles. the odontoblast process emerges from its apical pole. it is formed by microtubules, microfilaments and vesicles covered by membranes penetrating the dentinal tubules, isolated from the inter-tubular matrix, along the extent of the dentine. the objective of this study was to evaluate the efficacy of three staining techniques: hematoxylin-eosin, periodic acid-schiff and schmorl, by staining the process, from beginning to end, and compare the results with the erosion technique. thirty human teeth were employed in the trial; after their extraction the pulp was fixated, the pieces demineralized in nitric acid at 8%, the collagen filaments eliminated with type ii collage-nase, the tissue was stained, and the measurements were made. the portions with no pulp were prepared with the erosion technique. results: comparing the best results obtained by staining with the values obtained with the erosion technique, the former showed lower values. conclusion: staining techniques show lower density of the staining processes compared with the dentinal tubules in the erosion technique.
