RESUMEN
La rotura uterina es una complicación obstétrica cuyas consecuencias pueden ser graves. Se diagnostica principalmente antes o durante el trabajo de parto en mujeres con antecedente de cesárea y una extracción rápida del feto es necesaria. Sin embargo, pocos casos de dehiscencia uterina son diagnosticados a distancia del parto. Presentamos el caso de una paciente con útero cicatrizado, que consulta por metrorragia 27 días después de parto por vía vaginal, en la que se diagnosticó una dehiscencia uterina con consecuente histerectomía abdominal a través de una incisión de Pfannenstiel. Por medio de este caso se evaluarán los signos y síntomas para el diagnóstico temprano de una dehiscencia, permitiendo así proporcionar el tratamiento más conservador posible (AU)
Uterine rupture is an uncommon but potentially devastating maternal and obstetric complication that is usually diagnosed in women with a prior caesarean delivery before or during labour, leading to an emergency foetal extraction. However, there are very few reports of uterine rupture diagnosed in the postpartum period. We report the case of a patient with a scarred uterus who presenting with metrorrhagia 27 days after a vaginal delivery. A diagnosis of uterine dehiscence was made, requiring an abdominal hysterectomy through Pfannenstiel incision. Through this case we highlight the symptoms and signs to establish an early diagnosis, which allow provision of the most conservative treatment possible (AU)

Herpetic lesions most frequently occur on oral and genital areas. However, herpes simplex virus (HSV) can be a rare cause of breast infection. In few published articles, the route of transmission is predominantly from infant to mother. We report two cases about simultaneous mammary and extramammary (oral and genital) herpetic infection in nonlactating women. In both cases, HSV breast lesions were acquired by sexual contacts with partners who were asymptomatic HSV carriers. Through a review of literature, we highlight clinical signs for an early diagnosis. We also emphasize the advantage of the valacyclovir for treating this uncommon pathology.

Direct measurements of the effects of spatial separation between stimuli in whole report from brief visual displays are reported. The stimuli were presented on the periphery of an imaginary circle centered on fixation. In Experiment 1, each display showed two capital letters (letter height approximately equal 1.3 degrees, width approximately equal 0.9 degree, eccentricity approximately equal 5.5 degrees). The proportion of correctly reported letters was a strictly increasing, decelerating function of the spatial separation between the letters for center-to-center separations ranging from less than 2 degrees to more than 10 degrees of visual angle. Experiment 2 yielded similar results with triples of letters. Experiment 3 showed that accuracy increased with spatial separation for report of two short words, and Experiment 4 showed the same result for words presented upside down. The results are explained by a model of lateral masking (crowding) based on competitive interactions within receptive fields of cortical neurons.
