AbstractObjectivesTo identify the most common ultrasound patterns of markers and anomalies associated with Patau syndrome (PS), to explore the efficacy of multiparameter sonographic protocols in detecting trisomy 13 (T13) and to analyze the influence of maternal age (MA) on screening performance. Methods: The project was a prospective study based on singleton pregnancies referred for a first-trimester screening examination. The scan protocol included nuchal translucency (NT), fetal heart rate (FHR), secondary ultrasound markers [nasal bone (NB), tricuspid regurgitation (TR), ductus venosus reversed a-wave (revDV)] and major anomaly findings. Results: The study population comprised 6133 pregnancies: 6077 cases of euploidy and 56 cases of T13. Statistically significant differences were found in MA, FHR, NT, absence of NB, presence of revDV, TR and single umbilical artery. Fourteen cases of T13 (25%) demonstrated no markers of aneuploidy. The best general detection rate (DR) (DR of 78.6% with an false positive rate (FPR) of 1.2%) was obtained for a cutoff of 1/300 utilizing the “NT+T13” algorithm. The logistic regression model revealed that the central nervous system (CNS) anomalies had the greatest odds ratio (of 205.4) for T13. Conclusions: The effectiveness of the multiparameter sonographic protocol used for T13 screening showed promising results in patients older than 36 years and suboptimal results in patients between 26 and 36 years old. When screening for T13 left heart defects, CNS anomalies, abdominal anomalies, FHR above the 95th percentile, increased NT, revDV and lack of NB should receive specific attention.

ABSTRACT Objective To evaluate mode of injury and different management options reliant on types of nasal bone fractures. Study design Prospective analytical study. Subjects and methods Seventy-five patients with nasal bone fractured were clinically and radiologically evaluated and divided into different types according to Lee's classification. They were provided conservative, closed reduction and/or osteotomy according to the type of fracture and outcome noted. Results Lee's classification is found to be valid in real patient scenarios and using good radiological evaluation better post operative outcome can be achieved. For type 1 and 3 fractures, closed reduction and osteotomy are the treatment of choice. Conclusion We confirm that systematic approach on Lee's classification for nasal bone fracture can be used to select appropriate management strategy.
