RetCam is an excellent screening tool for the detection of retinopathy of prematurity (ROP). However, affordability is a barrier when adopting the use of RetCam in developing countries. We aimed to describe different stages of ROP using ultrasonographic B-scan and to evaluate the association between funduscopic examinations and ultrasonographic B-scan findings in premature neonates with ROP in ...
Background: The anticipation of a challenging airway can be demanding in emergency care settings. Due to the patient’s clinical condition, executing pre-intubation screening tests during management an situation sometimes troublesome. Ultrasonographic assessment may become helpful tool, but no specific sonographic measurements precisely visualize prospect meeting difficult airway. Therefore, pre...
In the second half of the 20 century, the prenatal diagnosis armamentarium changed dramatically with the introduction of amniocentesis and chorionic villus sampling. Both modalities are, however, invasive techniques and carry a certain risk, albeit low (0.5–1%), of pregnancy loss [1]. Routine noninvasive methods of prenatal diagnosis include firstand second-trimester ultrasonography and materna...
Developmental dysplasia of the hip (DDH) encompasses a wide spectrum of clinical severity, from mild developmental abnormalities to frank dislocation. Clinical hip instability occurs in 1% to 2% of full-term infants, and up to 15% have hip instability or hip immaturity detectable by imaging studies. Hip dysplasia is the most common cause of hip arthritis in women younger than 40 years and accou...
Congenital heart disease is the most common abnormality in the human fetus. Fetal echocardiography has been used to detect the majority of cardiac defects, and it is now part of the routine screening method for fetal evaluation. In this article, we present standard ultrasonographic views of the normal fetal heart obtained during the second trimester, first-trimester fetal echocardiography findi...
The authors consider the possibility of using color Doppler of the ductus venosus and the measurement of nuchal translucency as a screening test for alterations in fetal cardiac functions in the first trimester of gestation. Review of the literature suggests that the combination of the ultrasonographic measurement of nuchal translucency and Doppler at 10 and 14 weeks of gestation can be effecti...
OBJECTIVE To examine the interobserver variability for fetal biometric parameters and to focus on how this variability affects the combined first-trimester screening test results. METHODS Sixty-four singleton pregnancies who were scheduled for combined first-trimester screening were investigated. Two experienced sonographers performed all examinations at the same visit. The risk calculations ...
Ultrasound tissue Doppler imaging (US-TDI) has been used to diagnose regional wall motion (WM) abnormalities in coronary artery disease but has not been applied to oropharyngeal diseases. This study aimed first to validate an US-TDI method to assess cervical esophageal (CE) WM and secondly to use the method to evaluate CE WM in patients with oropharyngeal dysphagia (OD). First, we enrolled 22 h...
OBJECT The authors performed spinal ultrasonography and/or magnetic resonance (MR) imaging in 20 consecutive newborns with spinal strawberry nevi. METHODS In 15 patients the strawberry nevi were isolated and in five they were associated with other cutaneous markers of occult spinal dysraphism (OSD). In four of five patients with additional cutaneous markers, but in none of those without, MR i...
