RESUMO

OBJECTIVE: The objective of the study was to evaluate the longitudinal changes in maternal systolic and diastolic function in a series of women carrying an uncomplicated twin pregnancy. STUDY DESIGN: A series of women carrying a twin pregnancy underwent standard M-mode, 2-dimensional color Doppler, and tissue Doppler transthoracic echocardiography during the first (11-13 weeks), the second (20-23 weeks), the third (28-32 weeks) trimesters, and the postpartum (6 months after delivery). RESULTS: From January 2012 to September 2013, 30 women with an uncomplicated twin pregnancy were included in this prospective study. All the pregnancies were diamniotic including 24 dichorionic and 6 monochorionic sets. Overall, 60 live births were observed with a mean gestational age at delivery of 37 ± 1 weeks and a mean birthweight of 2532 ± 313 g. During pregnancy a significant worsening of left ventricle systolic function expressed by ejection fraction, fractional shortening and S1 longitudinal contractility decrease was observed. These findings also persisted at postpartum assessment. Regarding diastolic function, our data showed a significant progressive reduction of pulsed Doppler E-wave velocity and an increase of A-wave from the first to the third trimester. Similar changes were documented for tissue Doppler E1 and A1 peak velocities assessed at the level of the mitral and tricuspid annulus. After delivery diastolic findings returned to values comparable with those obtained in the first trimester. CONCLUSION: In uncomplicated twin gestations, significant changes in maternal systolic and diastolic function occur from the first to the third trimester. Moreover, although diastolic parameters normalize after pregnancy, a relative systolic dysfunction seems to persist after delivery.

RESUMO

Foreign body aspiration can produce serious pulmonary diseases. Timely diagnosis and appropriate treatment is important to prevent long-term complications in affected children. We report the case of a 15-month-old child with a 5-month history of regurgitation, vomiting, recurrent tracheobronchitis, and pneumonia. The diagnosis was gastroesophageal reflux. The laryngotracheal endoscopy revealed a rabbit vertebra partially obstructing the airway at the level of the cricoid cartilage. With a rigid bronchoscope and forceps equipped with a telescope, it was possible to disengage and extract the foreign body. Six months later endoscopic control revealed no residual alterations in the larynx and trachea.
