    Se evaluó la concentración de elementos químicos esenciales del musculo axial de las truchas arcoíris (Oncorhynchus mykiss) colectadas en dos provincias: Puno y Huancané, ubicadas al noreste del lago Titicaca. Para la caracterización química se empleó el método de Espectrometría de Absorción Atómica (ICP-OES), bajo el protocolo 7003 EPA 200.7. Los elementos químicos esenciales que se encontraron en el musculo axial de las truchas colectadas en la provincia de Puno fueron: Zn (15,00±0,95 mg/kg); Se (1,26±0,37 mg/kg); Al (2,03±0,23 mg/kg); Ca (513,33±112,40 mg/kg); Na (1733,33±152,75 mg/kg); Mg (496,00±35,12 mg/kg); K (11333,33±1154,70 mg/kg); Mn (0,07±0,02 mg/kg) y P (5066,67±251,66 mg/kg), mientras que la concentración de elementos esenciales en las muestras del musculo axial de las truchas colectadas en la provincia de Huancané fueron: Zn (14,30±3,48 mg/kg); Se (1,27±0,34 mg/kg); Al (0,76±0,15 mg/kg); Ca (663,33±170,10 mg/kg); Na (1733,33±513,16 mg/kg); Mg (586,67±15,28 mg/kg); K (11000,00±0,00 mg/kg); Mn (0,16±0,06 mg/kg) y P (5300,00±264,58mg/kg) estos no superan los límites máximos permisibles, por lo que constituyen una fuente importante de proteínas, además de los dos ácidos grasos omega-3 esenciales conocidos como DHA (ácido docosahexaenoico) y EPA (ácido eicosapentaenoico) y vitaminas, por lo que las truchas arcoíris (Oncorhynchus mykiss) de las zonas evaluadas, fueron aptas para el consumo humano, debido a que no superan los límites máximos permisibles de los elementos químicos analizados.

    Relación de la Lactancia Materna y Hábitos de Succión no Nutritiva con Maloclusión Dental
    (Elsevier BV, 2010) Alfredo Pelayo Calatayud Mendoza; PAOLA ASBÚN; ANDREA CRESPO A; Susana Gonzáles; ROSA PATIÑO
    Objectives: To analyze the effects of the maternal breast feeding over the development of the different structures that compose the estomatognatico apparatus, its preventive effects. Design: Case control cohort retrospective longitudinal. Place: Hospital del Nio Dr. Ovidio Aliaga Uria, in the city of La Paz. Participants: 500 children between three ands seven years old that come to the outpatient clinic and emergency ward. Material and Methods: The information was obtained with previous consent from the parents, questionnaire given to the mothers, that included: general information, time of breastfeeding, type of feeding, non nutritive suction habits: also we examined the children in the study and take their records in a history chart including: sex, age, postlacteum plane, occlusion classifi cation, presence of habits, presence of anomalies and we studied the possible associations between them. Results: Of the 500 children studied, 250 cases and 250 controls; 47% (n = 235) male and 53% (n = 265) female. The exclusive maternal breastfeeding during the fi rst six months of life represents a preventive factor for the development of altered occlusion, OR of 0.09 with (IC 95% 3.46-5.28). On the other hand feeding bottle feeding has a probability of altered occlusion OR of 18.2 (IC 95% 4.23-4.79). We found a statistically signifi cant association between the habits of non nutritive suction and altered occlusion OR 24.57 (IC 95% 2.55-3.01) between the fi rst three years of life. Depending of the type of feeding we observed that in those children who had feeding through bottle 64% had habits of non nutritive suction. The most frequent non nutritive suction habit is the digital suction with 53%, representing less percentages the bottle feeding with 28% and other habits like the lip interposition and tongue with 19%. Conclusions: The non nutritive suction habits and the bottle feeding in the fi rst months of life are the primary risk factor for the development of altered occlusion like deep bite in deciduous dentition and Class II of Angle in mixed dentition.
