The outcome of one-stage bilateral open reduction through a medial approach for the treatment of developmental dysplasia of the hip in children under 18 months was studied in 23 children, 18 girls and five boys. Their mean age at operation was 10.1 months (6 to 17) and the mean follow-up was 5.4 years (3 to 8). Acceptable clinical and radiological results were achieved in 44 (95.7%) and 43 (93.5%) of 46 hips, respectively. Excellent results were significantly evident in patients younger than 12 months, those who did not require acetabuloplasty, those whose ossific nucleus had appeared, and in those who did not develop avascular necrosis. One-stage bilateral medial open reduction avoids the need for separate procedures on the hips and has the advantages of accelerated management and shorter immobilisation and rehabilitation than staged operations.
The aim of this study is to define paediatric lateral humeral condyle fractures prone to later displacement. The authors reviewed 106 children who were treated surgically for this fracture. There were 74 boys and 32 girls with an age range of 3-10 years. The study included 27 minimally displaced and 79 displaced fractures. The average follow-up was 50 months. Binary logistic regression model indicated that 6-8-year-old children with minimally displaced fractures and who underwent immediate surgery have a better chance for satisfactory results. The authors concluded that routine use of 2 mm displacement for treatment decisions should be changed to avoid delayed surgery.
Acetabular cartilaginous angle is considered a reliable measurement to identify hips with DDH that will need later acetabuloplasty after successful closed reduction. The acetabular index is important in monitoring acetabular development, and reaching a value of less than 30 degrees 2 years after closed reduction is considered a good sign of acetabular development.
Introduction
Cardiac arrhythmias are regulary seen in patients following orthotopic heart transplantation (OHT). So far, there is no data available about the prevalence in a large cohort.
Methods
We retrospectively screened our database for subjects with OHT who received inpatient or outpatient treatment in our center between January 2000 and December 2018. All these patients were carefully reviewed with special attention to rhythm disturbances after successful transplantation.
Results
We identified a total number of 1890 subjects with history of OHT being treated in our center during the pre-defined time-period. The prevalence of supraventricular tachycardias was as follows: atrial fibrillation/atypical flutter and atrial ectopy 10%, AV-node-re-entry tachycardia 3%, typical atrial flutter 2% and higher degree AV-Block or Sick-Sinus-Syndrom (SSS) was 6%. Sustained ventricular tachycardia or ventricular premature contractions were present in 2%. Regarding the patients with arrhythmias, 13% received catheter ablation for arrhythmias, thereof 53% an atrial ablation (24% left atrial ablation), the remainder received a ventricular ablation.
Conclusion
In this very large cohort and following a long observational time, there was a higher incidence of atrial arrhythmias in patients following OHT as reported in healthy subjects with an emphasis on atrial fibrillation and flutter. This data gives a valuable background information on morbidity following OHT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
