:Valgus-varus Deformity (VVD) is an outward or inward deviation of the tibiotarsus or tarsometatarsus, which results in physical distress of chickens and economic loss in poultry industry. While the etiology and pathogenesis of VVD at the molecular level are still not fully understood so far. Here, based on a case/control design with VVD birds and normal birds, we identified genes and lncRNAs which associated with VVD using RNA sequencing. Transcriptome analysis revealed 231 differentially expressed mRNAs and 23 differentially expressed lncRNAs between case and control of leg cartilage. We identified the cis- and trans-regulatory targets of the differentially expressed lncRNAs, and we constructed a functional lncRNA-mRNA co-expression network. Analysis of the network showed that the differentially expressed mRNAs and the target genes of the differentially expressed lncRNAs were enriched in the signaling pathways associated with bone development, including p53, MAPK, Toll-like receptor, Jak-STAT, Hedgehog, and PPAR. The expression levels of DENND4A, FGF10, FGF12 and BMP3 were also determined in cartilage and other six tissues. Overall, our study predicted the mRNAs and lncRNAs related with leg diseases by transcriptome analyses, which might contribute to understand the etiology and pathogenesis of VVD. It established the foundation for the further research on the function of -mRNAs and lncRNAs in skeleton development.


: 外翻-内翻畸形 (VVD) 是指足前鼠或跗跖的向外或向内偏移,导致鸡的身体痛苦和家禽业的经济损失。VVD的病因和发病机制在分子水平上尚未完全阐明。在此,基于VVD鸟类和正常鸟类的病例/对照设计,我们使用RNA测序鉴定了与VVD相关的基因和lncrna。转录组分析揭示了腿部软骨病例和对照之间的 231 个差异表达mrna和 23 个差异表达lncRNAs。我们鉴定了差异表达lncRNAs的顺式和反式调控靶点,并构建了一个功能性lncRNA-mRNA共表达网络。网络分析表明,差异表达的mRNAs和差异表达的lncRNAs的靶基因富集在与骨发育相关的信号通路中,包括p53 、MAPK、Toll样受体、jak-STAT、Hedgehog和PPAR。还测定了软骨和其他 6 种组织中DENND4A、FGF10 、FGF12 和BMP3 的表达水平。总的来说,我们的研究通过转录组分析预测了与腿部疾病相关的mRNAs和lncRNAs,这可能有助于了解VVD的病因和发病机制。为进一步研究-mRNAs和lncRNAs在骨架发育中的功能奠定了基础。

METHODS::Impairments in social cognition have been frequently described in 22q11.2 deletion syndrome (22q11.2DS) and are thought to be a hallmark of difficulties in social interactions. The present study addresses aspects that are critical for everyday social cognitive functioning but have received little attention so far. Sixteen children with 22q11.2DS and 22 controls completed 1 task of facial expression recognition, 1 task of attribution of facial expressions to faceless characters involved in visually presented social interactions, and 1 task of attribution of facial expressions to characters involved in aurally presented dialogues. All three tasks have in common to involve processing of emotions. All participants also completed two tasks of attention and two tasks of visual spatial perception, and their parents completed some scales regarding behavioural problems of their children. Patients performed worse than controls in all three tasks of emotion processing, and even worse in the second and third tasks. However, they performed above chance level in all three tasks, and the results were independent of IQ, age and gender. The analysis of error patterns suggests that patients tend to coarsely categorize situations as either attractive or repulsive and also that they have difficulties in differentiating emotions that are associated with threats. An isolated association between the tasks of emotion and behaviour was found, showing that the more frequently patients with 22q11.2DS perceive happiness where there is not, the less they exhibit aggressive behaviour.

METHODS:BACKGROUND:We describe the first radiographic clinic in the literature for DDH and how this novel clinic can significantly improve the efficiency and cost-effectiveness of service in a tertiary referral centre. AIMS:A radiographic clinic for the management of developmental dysplasia of the hip was introduced in 2017 in our institution. We performed a detailed cost analysis to assess the economic savings made with the introduction of this new clinic. We assessed the efficiency of the service by identifying how many unnecessary outpatient visits were prevented. We also assessed the difference in times from referral to review between the two clinics. METHODS:Analysis of the clinic activity in 2017 was possible as all data was collected prospectively by the DDH CNS and stored in our database. Cost analysis was performed, and the savings made per patient along with the financial benefit to our institution was recorded. RESULTS:The new radiographic clinic reduced the cost of reviewing one patient by €162.51 per patient. There was a 73% discharge rate from the clinic which prevented 251 unnecessary patient visits to the outpatient department over the course of the year. There was a significant 11-day reduction in waiting times between referral and review when comparing the radiographic to the conventional clinic (p < 0.05). CONCLUSIONS:A radiographic clinic for the management of developmental dysplasia of the hip has a significant effect on the efficiency and overall cost-effectiveness of service provision in a tertiary referral centre.

METHODS:INTRODUCTION:Triple pelvic osteotomy (TPO) involves periacetabular osteotomies of the ilium, ischium, and pubis to reorient the acetabulum. This operation is indicated in certain situations for the treatment of developmental dysplasia of the hip, dysplastic neuromuscular hips, and for containment of the femoral head in cases of Legg-Calvé-Perthes disease. METHODS:This retrospective cohort study compares radiographic outcomes of patients who underwent TPO using two different techniques and describes a novel single-incision direct lateral approach. TPO was performed on 22 patients by the senior author. The first 10 patients underwent TPO through a single-incision anterolateral approach. The last 12 patients underwent TPO using the direct lateral approach. Preoperative and postoperative pelvic radiographs were reviewed for each patient, and the migration index and center-edge angle were recorded. RESULTS:The migration index and center-edge angle were evaluated and were not found to be significantly different between the anterolateral and direct lateral groups. The direct lateral approach is described. CONCLUSION:The direct lateral approach for TPO is equivalent to the anterolateral approach on radiographic evaluation. Advantages of the direct lateral approach include direct visualization of the ischial osteotomy, effective mobilization of the acetabulum, and safety of the sciatic nerve.
