Hallazgos ecográficos en trauma ocular / Ultrasound findings in ocular trauma

OBJETIVO: Evaluar las frecuencias de las distintas alteraciones oculares u orbitarias en pacientes con trauma ocular, mediante estudio ecográfico. MATERIALES Y MÉTODOS: Este estudio prospectivo y descriptivo incluyó a 100 ojos evaluados en el Instituto Conde de Valenciana debido a traumatismo ocular desde marzo hasta noviembre del 2014. Se realizó la exploración ecográfica empleando primariamente el ultrasonido modo B y solo el modo A estandarizado como método de correlación. Se recogieron la edad, género, tipo de trauma y los distintos hallazgos ecográficos encontrados. RESULTADOS: El trauma ocular fue más frecuente en hombres (83%) comparado con mujeres (17%); el ojo izquierdo fue el afectado en el 55% de las veces y el ojo derecho en el 45%; el 55% fueron traumas abiertos y el 45% traumas cerrados. La mayoría de los casos fueron pacientes jóvenes, con un promedio de edad de 33,7 años; el grupo etario más afectado fue entre los 41 y los 50 años. Dentro de las lesiones encontradas las más frecuentes fueron la hemorragia vítrea (45%) y el desprendimiento de hialoides posterior (38%), seguido del desprendimiento de retina (32%) y el desprendimiento coroideo (18%). CONCLUSIÓN: La ecografía se mantiene como el estudio de elección en pacientes con trauma ocular, ya que es un estudio sencillo, barato, no invasivo y que puede ser muy útil al brindar información diagnóstica y pronóstica. Este estudio demostró que el trauma es más común en hombres jóvenes y que la hemorragia vítrea es la lesión más comúnmente encontrada

OBJECTIVE: To evaluate the frequencies of various eye and/or orbital disorders by ultrasound examination in patients with ocular trauma. MATERIALS AND METHODS: This prospective and descriptive study was conducted on 100 patients with ocular trauma treated in the Conde de Valenciana Institute from March to November 2014. Ultrasound examination was performed primarily using ultrasound B mode, with standardised A mode only used as correlation method. Age, gender, type of trauma, and various ultrasound findings were recorded. RESULTS: Ocular trauma was more frequent in men (83%) compared to women (17%). The left eye was affected in 55%, and right eye in 45%, with 55% being open traumas and 45% blunt traumas. Most cases were young patients with a mean age of 33.7 years, with the group between 41 to 50 years being the most affected. Among the most frequent injuries found was the vitreous haemorrhage (45%) and posterior hyaloid detachment (38%), followed by retinal detachment (32%), and choroidal detachment (18%). CONCLUSION: Ultrasound remains as the investigation method of choice in patients with ocular trauma, since it is a simple, cheap and non-invasive study, and can be very useful in providing diagnostic and prognostic information. This study demonstrated that trauma is more common in young men, with vitreous haemorrhage as the most common finding

Detection of Epstein-Barr virus in saliva by real-time PCR.

The purpose of this investigation was to assess the salivary levels of Epstein-Barr virus (EBV) in patients with periodontitis using real-time PCR. EBV was detected in 16 out of 33 (48.5%) periodontitis patients and in 3 out of 20(15%) healthy subjects. The baseline mean values for bleeding on probing in EBV-positive patients were significantly higher than those in EBV-negative patients. A significant decrease in EBV levels was observed after initial periodontal treatment. Our findings indicate that levels of EBV in saliva may reflect the status of periodontal inflammation.

Detection of Streptococcus anginosus from saliva by real-time polymerase chain reaction.

AIMS: The purpose of the present investigation was to assess the salivary levels of Streptococcus anginosus in periodontitis patients. METHODS AND RESULTS: The salivary levels of Strep. anginosus were assessed using real-time polymerase chain reaction (PCR). Streptococcus anginosus was detected in 28 of 37 (75.6%) of periodontitis patients and in three of the 20 (15%) healthy subjects. The mean values for bleeding on probing and probing depth in positive patients were statistically higher than those in negative patients. A significant decrease in Strep. anginosus levels was observed after periodontal treatment. CONCLUSIONS: Although the levels of Strep. anginosus are extremely low, they may reflect the status of periodontal health. SIGNIFICANCE AND IMPACT OF THE STUDY: Real-time PCR is a useful method for obtaining the relative quantities of Strep. anginosus from saliva samples and for monitoring the effect of therapy.
