No-Prep semidirect composite resin veneer. A Step-by-Step case report in a deciduous canine with a one-year follow-Up / Carilla de resina semidirecta sin preparación. Un reporte paso a paso en un canino deciduo con seguimiento de un año

Abstract The presence of deciduous canines in adulthood may be of aesthetic concern for patients. Many clinical alternatives include surgical and orthodontic treatment. Since patients search for highly esthetic results and more conservative alternatives, the present clinical report describes a treatment for deciduous canine through an indirect composite resin veneer and an indirect composite resin fragment restoration in a premolar to improve esthetic outcomes with a one-year follow up.

Resumen La presencia de caninos deciduos en adultos puede ser de preocupación estética por parte de los pacientes. Diversas alternativas clínicas pueden incluir tratamientos quirúrgicos y ortodóncicos. Desde que los pacientes buscan por resultados de alta estética y cada vez más conservadores, es que el presente caso clínico describe el tratamiento de un canino deciduo mediante una carilla indirecta de resina compuesta junto a un fragmento indirecto de resina de un premolar con el fin de mejorar los resultados estéticos, y con un año de seguimiento.

Type of delivery and gestational age is not affected by pregnant Latin-American women engaging in vigorous exercise. A secondary analysis of data from a controlled randomized trial / El tipo de parto y la edad gestacional no se afectan por el ejercicio aeróbico vigoroso en mujeres gestantes latinas. Análisis secundario de un ensayo clínico

ABSTRACT Objective There is controversy concerning whether exercise during pregnancy may increase preterm delivery risk and type of delivery. The effect of pregnant Latin-American women engaging in vigorous exercise during the second and third trimester was examined regarding type of delivery and gestational age. Materials and Methods This was a secondary analysis of data from a controlled randomized trial for determining the influence of physical exercise on pregnant women's endothelial function. The study included 35 nulliparous women, gestational week 16-20 attending prenatal care at three tertiary hospitals in Colombia, who were randomly assigned to one of two groups. The experimental group engaged in aerobic exercise involving 55 % - 75 % maximum heart rate for 60 min, three times a week for 12 weeks. The control group engaged in their usual physical activity. Maternal weight, height, weight gain, blood pressure and type of delivery were recorded; gender, abdominal and head circumference (cm), weight (g), height (cm), vitality (Apgar score at 1 and 5 min) and gestational age at the time of delivery (in weeks, days) were recorded for the newborn. Results There was no difference in type of delivery by the end of the 12-week program (p>0.05), nor regarding newborn anthropometric variables, Apgar score, or maternal variables concerning weight, height, relative weight gain, blood pressure or weeks of gestation (p>0.05). Conclusion The potential public health benefits of vigorous exercise were enormous. This study support ed existing guidelines indicating that Latin-American women may begin or maintain an on-going exercise program during pregnancy. Trial registration: NCT00741312.

Objetivo Existe controversia acerca del efecto del ejercicio físico vigoroso (EFV) durante el embarazo por sus posibles consecuencias en el tipo de parto y la edad gestacional. El objetivo de este estudio fue evaluar el efecto del EFV durante el segundo y tercer trimestre, en mujeres gestantes latinas sobre el tipo de parto y la edad gestacional. Materiales y Métodos Se trata de un análisis secundario de un ensayo clínico controlado en 35 gestantes, asignadas al azar en dos grupos. Grupo experimental (n=18): EFV entre el 55 % y 75 % de la FC max, por 60 min, 3 veces por sem. Por 12 sem. Grupo Control (n=17): actividad física cotidiana y control prenatal habitual. Se registraron en las maternas: peso, talla, ganancia de peso, presión arterial y tipo de parto. En el recién nacido se registró: género, perímetro cefálico y abdominal (cm), peso (g), talla (cm), semanas de gestación, vitalidad (score Apgar al 1 y 5 min), y semanas de gestación. Resultados No se encontraron diferencias estadísticamente significativas respecto al tipo de parto (p>0,05). Tampoco en las variables antropométricas del recién nacido, ni en las variables maternas: peso, talla, ganancia de peso, presión arterial o semanas de gestación (p>0,05). Conclusión Los beneficios potenciales en salud pública del efecto EFV durante la gestación son importantes y este estudio favorece que mujeres latinas puedan comenzar o mantener un programa de ejercicios durante el embarazo. Trial registration: NCT00741312.

Multicenter survey of badminton-related eye injuries

Objective: To determine the patient profile and risk factors for badminton-related eye injuries in Metro Manila. Methods: We conducted a cross-sectional survey of badminton-related eye injuries in Metro Manila. A survey form was sent to 13 ophthalmologists who were asked to report on patients treated for badminton-related eye injuries from July 1 to December 1, 2004. The following data were collected: patient age, gender, and sports experience; details of eye injury; use of protective eyewear; and visual outcomes. Logistic regression analysis was performed to predict sight-threatening injuries. Results: The average patient age was 34.7 +/- 6.2 years (range 18 to 46). There were more males than females (1.55:1). All patients sustained eye injury while playing doubles. None of the patients were wearing protective eyewear at the time of injury. Blunt trauma due to shuttlecock impact was the cause of injury in 74 % of cases. The most common ocular findings were iridocyclitis (n = 11), secondary glaucoma (n = 6), and hyphema (n = 5). Twenty-nine sight-threatening conditions were reported. Six (26 %) patients developed chronic ocular sequelae. Conclusion: Sight-threatening injuries can occur in individuals playing badminton. While vision loss is uncommon, treatment outcomes are generally good. Since all injuries were sustained without the use of protective eyewear, ophthalmologists have a responsibility to promote its use when playing badminton.
