General practitioners' satisfaction with and attitudes to out-of-hours services

Background  

In recent years, Dutch general practitioner (GP) out-of-hours service has been reorganised into large-scale GP cooperatives. Until now little is known about GPs' experiences with working at these cooperatives for out-of-hours care. The purpose of this study is to gain insight into GPs' satisfaction with working at GP cooperatives for out-of-hours care in separated and integrated cooperatives.     

Chronic scapholunate dissociation: ligament reconstruction combining a new extensor carpi radialis longus tenodesis and a dorsal intercarpal ligament capsulodesis

Scapholunate dissociation (SLD) is the commonest cause of carpal instability and wrist osteoarthrosis. The value of early diagnosis and treatment of this injury is well established in the literature. When a partial or total rupture of the scapholunate ligament is treated with early anatomic reduction and repair, functional results may be good to excellent. However, if this ligament is not addressed acutely then an overall carpal malalignment may seem progressively as a result of failure of the secondary scaphoid stabilizers. Chronic SLD will lead to scapholunate advanced collapse and progressive painful arthritis of the wrist. Although most surgeons agree that operative intervention is indicated, no clear consensus exists on the best treatment for patients with chronic SLD. Several procedures have been described that include some sort of partial fusion, capsulodesis, tenodesis, or bone-ligament-bone graft. If there is no evidence for arthrosis, soft-tissue procedures using either capsulodesis or tenodesis may be carried out in an attempt to preserve radiocarpal and intercarpal motion whereas avoiding fusion. This article describes a scapholunate ligament reconstruction combining a new dorsal extensor carpi radialis longus tenodesis and a dorsal capsulodesis for the treatment of chronic SLD.     

Current structures of cardiac centers

The "Working Group for Congenital Heart Surgery and Pediatric Heart Surgery" of the German Society for Thoracic and Cardiovascular Surgery (GSTCVS) has analysed and recommended structures for congenital heart surgery departments in Germany. The document was worked out according to a similar paper approved earlier by the European Association for Cardio-thoracic Surgery (EACTS). The "Working Group" unifies the majority of cardiac surgeons involved in congenital heart surgery in Germany. Current structures of cardiac centers vary. Therefore the aim of this document is to elucidate additional structural needs for both highly specialized institutions and those for standard care. Specialized centers should allow for treatment of newborns and adult patients with congenital heart disease, include implementation of assist devices and transplantation, possess research facilities and ensure highest standards of education and training. Standard care units do not necessarily need to cater for the above mentioned spectrum. However, the evaluation of quality of care should be given priority in all centers involved in care of patients with congenital heart disease. Data acquisition and transfer must be guaranteed to both the GSTCVS and EACTS in order to ensure national and international comparison of surgical results. This may also give further guidance for improved patient care.     

Contribution of VANGL2 mutations to isolated neural tube defects

Kibar Z, Salem S, Bosoi CM, Pauwels E, De Marco P, Merello E, Bassuk AG, Capra V, Gros P. Contribution of VANGL2 mutations to isolated neural tube defects. Vangl2 was identified as the gene defective in the Looptail (Lp) mouse model for neural tube defects (NTDs). This gene forms part of the planar cell polarity (PCP) pathway, also called the non‐canonical Frizzled/Dishevelled pathway, which mediates the morphogenetic process of convergent extension essential for proper gastrulation and neural tube formation in vertebrates. Genetic defects in PCP signaling have strongly been associated with NTDs in mouse models. To assess the role of VANGL2 in the complex etiology of NTDs in humans, we resequenced this gene in a large multi‐ethnic cohort of 673 familial and sporadic NTD patients, including 453 open spina bifida and 202 closed spinal NTD cases. Six novel rare missense mutations were identified in seven patients, five of which were affected with closed spinal NTDs. This suggests that VANGL2 mutations may predispose to NTDs in approximately 2.5% of closed spinal NTDs (5 in 202), at a frequency that is significantly different from that of 0.4% (2 in 453) detected in open spina bifida patients (p = 0.027). Our findings strongly implicate VANGL2 in the genetic causation of spinal NTDs in a subset of patients and provide additional evidence for a pathogenic role of PCP signaling in these malformations.     

Blood patch treatment of chylothorax following transthoracic oesophagogastrectomy: a novel technique to aid surgical management

Chylothorax is a well-recognised complication of oesophagectomy, occurring in around 3% of cases. If managed conservatively, the mortality rate can be over 50%. We describe our experience of managing a patient with a chylothorax following oesophagectomy, and the use of a blood patch (a novel technique) to overcome persistent leakage following re-operation. The authors feel that this technique has the potential for a wider application in the treatment of chyle leak, especially if combined with minimally invasive or radiological techniques.     

Assessment of right ventricular systolic function using tricuspid annular-plane systolic excursion in Nigerians with systemic hypertension

Aim

Right ventricular (RV) systolic function in patients with hypertensive heart disease (HHD) is not well characterised. The primary aim of this study was to assess the systolic function of the right ventricle in patients with HHD using tricuspid annular-plane systolic excursion (TAPSE).

Methods

The study was cross-sectional in design and carried out in Kano, Nigeria. Patients were recruited if they had HHD on echocardiography and were at least 15 years of age. Patients with other cardiac pathologies such as ischaemic and valvular heart diseases were excluded. Patients were considered to have abnormal RV systolic function if they had reduced values of TAPSE (< 15 mm). A p-value of < 0.05 was considered statistically significant.

Results

A total of 186 patients were serially recruited over seven months. Of these, 131 (70.4%) had normal RV systolic function (group 1) and 55 patients (29.6%) had abnormal function (group 2). Group 2 patients were older (p = 0.002) and had a higher prevalence of peripheral oedema (p = 0.002), moderate to severe dyspnoea, higher heart rate and lower left ventricular ejection fraction (p < 0.001). Atrial arrhythmias were also more prevalent among group 2 patients (p < 0.05). The best correlate to TAPSE was the septal mitral annularplane systolic excursion (r = +0.541, p < 0.001). Several variables such as age predicted the presence of reduced TAPSE.

Conclusion

The study found that almost one-third of patients with HHD in Kano had RV systolic dysfunction as defined by reduced TAPSE, and these patients had a greater prevalence of factors associated with morbidity and mortality.
