Abstract

BACKGROUND:Outcomes for a continuously applied alveolar bone grafting protocol, established in 1982, are reported and compared to previously published outcomes from the authors' unit and elsewhere. METHODS:A descriptive, retrospective cohort study of alveolar bone grafting outcomes at a tertiary referral cleft center was performed. Records of all alveolar bone grafts between 2002 and 2014 were reviewed (224 grafts). Three-year postoperative periapical radiographs were evaluated using the Bergland, Kindelan, and standardized way to assess graft scores by an external rater. Incomplete records, a syndromic diagnosis, or primary surgery performed elsewhere resulted in 123 grafts being excluded, leaving 101 grafts for assessment. The distribution of scores was compared to the authors' previous studies and international reports. The authors also tested for any impact on the outcome based on cleft type, laterality, timing for incisor or canine eruption, and surgeon experience. RESULTS:A total of 95.6 percent of applicable grafts (66 of 69) were considered "successful" by Bergland scores and 96 percent by Kindelan scores. Eighty-nine percent of grafts were "very good" based on standardized way to assess graft score. No significant differences were detected in outcomes based on timing, cleft type, or laterality. Surgeon experience had a significant impact (p < 0.05) on outcome for Bergland and Kindelan scores. Distribution of Bergland scores did not differ from the authors' earlier studies demonstrating consistent outcomes for over 30 years. CONCLUSIONS:The Western Australian alveolar bone grafting protocol has consistently achieved a very high success rate (96 percent) for over 30 years despite multiple staff changes. These results compared well with best-reported outcomes from worldwide cleft centers. Surgeon training and experience were significant in achieving these outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE:Therapeutic, IV.

摘要

背景: 报告了 1982 年建立的持续应用牙槽骨移植方案的结果,并与作者单位和其他地方以前发表的结果进行了比较。 方法: 进行了一项关于三级转诊腭裂中心牙槽骨植骨结局的描述性、回顾性队列研究。回顾了 2002 年至 2014 年间所有牙槽骨移植物的记录 (224 个移植物)。使用Bergland、Kindelan和标准化方法评估三年术后根尖周x线片,通过外部评定者评估移植物评分。记录不完整、综合征诊断或其他地方进行的初次手术导致 123 例移植物被排除,留下 101 例移植物供评估。将评分分布与作者以前的研究和国际报告进行比较。作者还根据裂隙类型、偏侧性、切牙或尖牙萌出的时间以及外科医生的经验,测试了对结局的任何影响。 结果: 共有 95.6% 的适用移植物 (69 例中的 66 例) 被Bergland评分认为 “成功”,96% 被Kindelan评分认为 “成功”。根据评估移植物评分的标准化方法,89% 的移植物 “非常好”。未检测到基于时间、裂隙类型或偏侧性的结局存在显著差异。外科医生的经验对Bergland和Kindelan评分的结果有显著影响 (p <0.05)。Bergland评分的分布与作者早期的研究无差异,证明 30 多年来的结果一致。 结论: 西澳大利亚牙槽骨移植方案 30 多年来一直取得了非常高的成功率 (96%),尽管有多个工作人员的变化。这些结果与来自全球腭裂中心的最佳报告结果进行了良好的比较。外科医生的培训和经验对实现这些结果意义重大。 临床问题/证据水平: 治疗性,IV。

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.
