Temporale Enzephalozelen – eine neue Ursache von Temporallappenepilepsien?

Clinical Epileptology - Temporale Enzephalozelen sind bisher nur in wenigen Fällen als Ursache von symptomatischen Epilepsien beschrieben worden. Zunehmende Beschreibungen in Fallserien weisen...     

An unusual mid term complication of coronary rupture

A 55-year-old man was admitted with a four-month history of lethargy, dyspnea and ascites. An idiopathic liver cirrhosis was suspected to be responsible for these symptoms and for elevated hepatic enzymes on blood tests. A few months before he had an angioplasty on the left anterior descending artery for an acute coronary syndrome (ACS). The intervention was complicated by coronary perforation which required the implantation of a polytetrafluoroethylene-covered (PTFE) stent to seal the rupture. On admission, pressure measurements during cardiac catheterism revealed a typical right ventricular dip-plateau consistent with the diagnosis of constrictive pericarditis (CP). Magnetic resonance imaging (RMI) showed localized pericardial thickening next to the right ventricle. We suspect hemopericardium, due to coronary perforation, is responsible for constrictive pericarditis. This mid-term complication of coronary rupture has not been reported before and should be suspected in this particular clinical setting.     

Salmonella aortic valve endocarditis presenting with rupture of a femoral artery mycotic aneurysm

The incidence of Salmonella enteritidis infections has greatly increased over the last few years. Cardiovascular are amongst the most severe extra-digestive complications. The authors report a case of Salmonella enteritidis presenting with rupture of a femoral artery mycotic aneurysm in a chronic alcoholic patient. Salmonella enteritidis was isolated from blood cultures and the operation specimen after the obligatory limb amputation. The outcome was finally favourable after appropriate antibiotic therapy with a residual, stable grade 3 aortic regurgitation. This rare condition is generally observed in immuno-compromised subjects and carries a high mortality (40 to 70% of cases). The initial infectious signs may be masked, and, in these cases, rupture of an aneurysm is often the mode of presentation. Rapid treatment is essential with, ideally, resection of the aneurysm with reestablishment of arterial continuity and adapted, prolonged antibiotic therapy.     

Direct detection of Staphylococcus aureus from adult and neonate nasal swab specimens using real-time polymerase chain reaction

Nasal carriage of Staphylococcus aureus is considered a source of subsequent infection in health care settings. Utilization of real-time polymerase chain reaction (PCR) for detection of S. aureus has the potential to dramatically affect infection control practice by rapidly identifying S. aureus-colonized patients. We developed and validated the use of real-time PCR for detection of S. aureus colonization in two patient populations. Paired nasal swabs were collected from 299 neonates and from 151 adult patients at Evanston Hospital. One swab was used for culture and the other placed into a bacterial lysis solution containing achromopeptidase. The DNA liberated was used as the template for real-time PCR with primers for the femA gene. SYBR Green was used for amplicon detection. In the neonatal population the sensitivity, specificity, predictive value positive and predictive value negative for culture and PCR was 92% versus 96%, 100% versus 100%, 100% versus 100%, and 98% versus 99%, respectively. In the adults the results were 90% versus 100%, 100% versus 98%, 100% versus 96%, and 95% versus 100%, respectively. Real-time PCR was able to detect S. aureus in 2 hours compared to 1 to 4 days for culture and provided sensitivity equal to or greater than culture.     

An evaluation of a strategy to improve the support of orthopaedic nurses through a team preceptorship programme

Transition to a new work area is often stressful for both experienced and new graduate nurses. It is essential that the new graduate be supported through this transition period to enable them to adjust to the environment itself, refine knowledge, and develop skills specific to their chosen clinical stream. In past years, several strategies have been designed with varying levels of success.This study evaluates an Australian transition support model, where the fundamental difference is that the management of the program is facilitated by a nurse possessing refined leadership, communication, clinical and organisational skills.The model has been evaluated on its effectiveness in meeting specific outcomes. The findings revealed that this coordinated team approach provided increased support for the new graduate, reduced the stress and workloads on the preceptors, whilst promoting confidence in the new starters and preventing conflict between preceptors and preceptees. The Coordinator’s role was shown to be an effective and crucial component in the Coordinated Team Preceptorship Model (CTPM) and findings illustrated that a team preceptorship model is not sustainable without a Coordinator.

Phaeochromocytoma, new genes and screening strategies

Following recent advances in the genetics of phaeochromocytomas and paragangliomas, the members of the European Network for the Study of Adrenal Tumours (ENS@T) Phaeochromocytoma Working Group have decided to share their genotyping data and to propose European recommendations for phaeochromocytoma/functional paraganglioma (PH/FPGL) genetic testing. Germline DNA from 642 patients was analysed by ENS@T teams. In 166 patients (25.9%) the disease was familial and caused by germline mutations in VHL (56), SDHB (34), SDHD (31), RET (31) or NF1 (14), causing von Hippel-Lindau disease, SDHB- or SDHD-PH/FPGL syndromes, multiple endocrine neoplasia type 2 (MEN 2) and type 1 neurofibromatosis (NF1), respectively. In almost 60% of inherited cases it was possible to formulate a probable genetic diagnosis based on family history and/or typical syndromic presentation. Genetic testing revealed mutations in 12.7% of cases with an apparently sporadic presentation. Several clinical characteristics, such as young age at onset, the presence of bilateral, extra-adrenal or multiple tumours or a malignant tumour, should be seen as indications for genetic testing. The ENS@T Phaeochromocytoma Working Group recommends the genetic testing of all patients with PH and FPGL and suggests a practice algorithm for the management of their exploration.
