Ultrasound techniques for the detection of developmental dysplasia of the hip: a systematic review and meta-analysis.

Background: Developmental dysplasia of the hip (DDH) encompasses a broad spectrum of hip pathologies, including femoral or acetabular dysplasia, hip instability, or both. According to the medical literature, ultrasonography is the most reliable diagnostic method for DDH. Several techniques for the assessment of hips in newborns and infants, using ultrasonography, have been described.

Efficacy and safety of a device used to prevent fogging and residue buildup on surgical optics during video-assisted thoracic surgical procedures (LacrimaSurg): a pilot in vivo study in 30 patients.

Introduction: Nowadays the majority of the surgical procedures are video surgeries. Despite technological advances, some problems remain. The buildup of residues in front of the lens is an example of this problem.

Prevalence of Developmental Dysplasia of the Hip in a Maternity Hospital in São Paulo, Brazil.

 To evaluate the prevalence of developmental dysplasia of the hip (DDH), that is, hips classified as Graf type-IIc or higher, among a sample of the population of newborns aged from 0 to 3 days of life, and to correlate the findings with the main risk factors described in the literature.  An observational, cross-sectional, prospective study on a sample of newborns at a Maternity Hospital School in the city of São Paulo, Brazil, to assess the prevalence of DDH diagnosed by the Graf method and verify its correlation with the risk factors.  A total of 678 newborns underwent hip ultrasound (1,356 hips).

Measurement of Pubofemoral Distance in the Diagnosis of Developmental Dysplasia of the Hip: Sensitivity and Specificity.

Objectives: To evaluate the accuracy of measurement of the pubofemoral distance (PFD) for the diagnosis of developmental dysplasia of the hip (DDH), using the Graf method as the reference standard.

Methods: This was a prospective diagnostic accuracy study evaluating 1980 hips in at-risk neonates. The PFD measurement and the Graf method were performed at the same opportunity, with the hips in the same position (slightly flexed, adducted, and medially rotated).
