Abnormal sonographic appearances of the yolk sac: which can be associated with adverse perinatal outcome?

Aims: The present study aimed to determine whether yolk sacs with abnormal sonographic appearance are associated with adverse perinatal outcomes in both early and late gestation.

Material And Methods: A total of 305 viable singleton pregnancies with gestational age of 6 to 9 weeks were prospectively evaluated with respect to perinatal outcomes and sonographic characteristics of the yolk sacs.

Results: An abnormal yolk sac was found in 66 pregnancies.

Unusual manifestation of acute retrocecal appendicitis: pericholecystic fluid.

Subhepatic-retrocecal appendicitis is a rare entity in which the diagnosis is challenging. In patients presenting with right abdominal pain with atypical clinical, laboratory and ultrasound (US) findings, acute appendicitis should be eliminated with computed tomography (CT). Multi-detector CT (MDCT) can be used effectively for the diagnosis of retrocecal appendicitis without additional preparation or focused examination.

Frequency of a persistent yolk sac and its relationship with the gestational outcome.

Objectives: This study aimed to determine the frequency of a persistent yolk sac in pregnancies at 12 to 13 weeks and to investigate whether a persistent yolk sac is associated with an adverse gestational outcome.

Methods: This study reviewed a total of 282 women who had normal singleton pregnancies with a gestational age of 12 weeks to 13 weeks 6 days and who were consecutively admitted to the study center for first-trimester screening (for chromosomal abnormalities) between April 2010 and February 2011. A persistent yolk sac has been defined as a yolk sac that has achieved a diameter of 5.

Real-time sonoelastography of the Achilles tendon: pattern description in healthy subjects and patients with surgically repaired complete ruptures.

Objective: The purpose of this study is to describe the elastographic appearance of the Achilles tendon in healthy subjects and patients with surgically repaired complete ruptures.

Materials And Methods: Nineteen Achilles tendons of 16 amateur footballers with surgically repaired complete ruptures and their contralateral asymptomatic Achilles tendons were assessed with ultrasound and real-time sonoelastography. Additionally, 40 asymptomatic Achilles tendons of 20 healthy amateur footballers were assessed.

Prevalence of scrotal calculi and their relationship with pain.

Purpose: The purpose of this study was to determine the frequency of scrotal calculi in men referred for scrotal ultrasonography (US), to identify any associated pathologies, and to investigate if any relationship exists between scrotal lithiasis and pain.

Materials And Methods: This was a retrospective study in which 4084 scrotal US examinations in 3435 men were evaluated. Scrotal US was performed using a high-frequency linear transducer.
