OBJECTIVES:Congenital midline cervical cleft (CMCC) is a rare congenital anterior neck anatomical anomaly. We present the case of two related patients (grandchild and maternal grandmother) who were both born with a congenital midline cervical cleft along with genetic analysis. METHODS:Clinical examination of both patients and surgical excision of the grandchild was performed. Genetic analysis with exome sequencing (ES) was conducted for both patients. RESULTS:Genetic analysis with exome sequencing (ES) revealed apparently novel single nucleotide variants in 66 genes present in both proband and grandmother. Five of these variants are predicted to cause frameshifting in the coding region of the respective genes and truncated proteins (OVGP1, TYW1B, ZAN, SSPO, FOLR3). Two of these genes (TYW1B and SSPO) have homozygous indel mutations in both patients. CONCLUSIONS:To our knowledge, this is the first case of two related patients with a congenital midline cervical cleft. The results of our genetic analysis reveal potential relevance to CMCC development.


目的: 先天性颈中线裂 (CMCC) 是一种罕见的先天性颈前解剖异常。我们介绍了两名相关患者 (孙子和外祖母) 的病例,他们都出生时患有先天性中线颈椎裂,并进行了遗传学分析。 方法: 对 2 例患者进行临床检查,并手术切除孙子。对两例患者进行了外显子组测序 (ES) 遗传学分析。 结果: 用外显子组测序 (ES) 进行的遗传分析揭示了先证者和祖母中存在的 66 个基因中明显新的单核苷酸变异。预测其中 5 种变异会导致各自基因和截短蛋白编码区的移码 (OVGP1 、TYW1B、ZAN、SSPO、for3)。其中两个基因 (TYW1B和SSPO) 在两个患者中均有纯合indel突变。 结论: 据我们所知,这是两例先天性中线颈椎裂相关患者的第一例。我们的遗传分析结果揭示了与CMCC发育的潜在相关性。

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.
