Hospital without dyspnea： rationale and design of a multidisciplinary intervention

Dyspnea is a common and disabling symptom of respiratory and heart diseases, which is growing in incidence. During hospital admis- sion, breathlessness is under-diagnosed and under-treated, although there are treatments available for controlling the symptom. We have developed a tailored implementation strategy directed to medical staff to promote the application of these pharmacological and non-pharmacological tools in dealing with dyspnea. The primary aim is to decrease the rate of patients that do not receive an adequate relief of dyspnea. This is a four-stage quasi-experimental study. The intervention consists in two teaching talks that will be taught in Cardiology and Respiratory Medicine Departments. The contents will be prepared by Palliative Care specialists, based on available tools for management of dyspnea and patients＇ needs. A cross-sectional study of dyspnea in hospitalized patients will be performed before and after the intervention to ascertain an improvement in dyspnea intensity due to changes in medical practices. The last phase consists in the creation of consensus protocols for dyspnea management based in our experience. The results of this study are expected to be of great value and may change clinical practice in the near future and promote a changing for the better of dyspnea care.

Hip Arthroscopy in Children under the Age of Ten

引用

Open Journal of Orthopedics 2013年第1期3卷 41-48页

作者： Oliver Eberhardt Thomas Wirth francisco fernandez fernandez Orthopaedic Department Olgahospital Stuttgart Stuttgart Germany.

Arthroscopic hip surgery has become an established diagnostic and therapeutic method for addressing different hip pathologies. This paper focuses on hip arthroscopy for treating hip disorders in children under the age of 10. Arthroscopic hip surgery was performed 30 times on 24 children to address various hip pathologies. Indications were septic arthritis, benign soft tissue tumors, traumatic and congenital hip dislocation, juvenile idiopathic arthritis and osteochondroma of the acetabulum. Diagnostic arthroscopy was technically feasible in all cases. All cases of septic arthritis were successful treated using arthroscopic lavage and antibiotics. In the miscellaneous cases (benign fibrous tumor, juvenile idiopathic arthritis, osteochondroma congenital hip dislocations and traumatic hip dislocation) 4 hips had additional open surgery including surgical dislocation with synovectomy, open reduction and stabilization of the fractured posterior rim of the acetabulum, acetabulopasty and open resection of an osteochondroma with acetabuloplasty. In conclusion arthroscopic hip surgery is an additional diagnostic and therapeutic method that is suitable for treating different hip pathologies in children under the age of 10. Primary treatment of septic arthritis can be done easy by hip arthroscopy. Using cannulated mini arthroscopic hip instruments (2.7 mm), the range of application can be expanded to include treatment of very young infants. Hip arthroscopy can reduce the need of open surgery but cannot replace bony procedures in hip surgery.

End-of-life care in a cardiology department： have we improved？

Background End-of-life care is not usually a priority in cardiology departments. We sought to evaluate the changes in end-of-life care after the introduction of a do-not-resuscitate （DNR） order protocol. Methods ＆ Results Retrospective analysis of all deaths in a cardiology department in two periods, before and after the introduction of the protocol. Comparison of demographic characteristics, use of DNR orders, and end-of-life care issues between both periods, according to the presence in the second period of the new DNR sheet （Group A）, a conven- tional DNR order （Group B） or the absence of any DNR order （Group C）. The number of deaths was similar in both periods （n = 198 vs. n = 197）. The rate of patients dying with a DNR order increased significantly （57.1% vs. 68.5%; P = 0.02）. Only 4% of patients in both periods were aware of the decision taken about cardiopulmonary resuscitation. Patients in Group A received the DNR order one day earlier, and 24.5% received it within the first 24 h of admission （vs. 2.6% in the first period; P 〈 0.001）. All patients in Group A with an implantable cardioverter defibrillator （ICD） had shock therapies deactivated （vs. 25.0% in the first period; P = 0.02）. Conclusions The introduction of a DNR order protocol may improve end-of-life care in cardiac patients by increasing the use and shortening the time of registration of DNR orders. It may also contribute to increase ICD deactivation in patients with these orders in place. However, the introduction of the sheet in late stages of the disease failed to improve patient participation.

作者： Aitor Uribarri Iria AGonzalez Esther Perez-David francisco fernandez-Aviles Cardiology Department Hospital General Universitario“Gregorio Maranon”MadridSpain

We present the case of an unusual presentation of Dressler’s syndrome and the important role of new imaging techniques in its diagnosis. A 42-year-old man was admitted with progressive dyspnoea and pleuritic chest pain during the last two months. Physical examination showed signs of hemodynamic instability (BP 75/40, HR 120 bpm). X-Ray showed cardiomegaly and electrocardiogram was suggestive of chronic anterior myocardial infarction. Transthoracic echocardiography showed pericardial effusion with signs of hemodynamic compromise. Emergent cardiac surgery was performed with suspicion of cardiac rupture. Only fibrinous material and serous fluid was found. 72 hours later he required reoperation because of recurrence of cardiac tamponade. Pleuropericardial window was made. Anti-inflammatory treatment was initiated. At discharge a magnetic resonance imaging study was performed. Diffuse pericardial inflammation consistent with a diagnosis of Dressler’s syndrome (DS) was demonstrated in T2- weighted black-blood and late enhancement sequences. One month later neither pleural nor pericardial effusion had recurred. Postinfarction pericardial effusions are common and magnetic resonance imaging has proven useful in determining its aetiology.

An approximate Kerr-Newman-like metric endowed with a magnetic dipole and mass quadrupole

引用

Communications in Theoretical Physics 2024年第8期76卷 124-138页

作者： francisco Frutos-Alfaro Space Research Center and School of Physics University of Costa RicaSan PedroSan JoseCosta Rica

Approximate all-terrain spacetimes for astrophysical applications are presented. The metrics possess five relativistic multipole moments, namely, mass, rotation, mass quadrupole, charge,and magnetic dipole moment. All these spacetimes approximately satisfy the Einstein-Maxwell field equations. The first metric is generated using the Hoenselaers-Perjés method from given relativistic multipoles. The second metric is a perturbation of the Kerr-Newman metric, which makes it a relevant approximation for astrophysical calculations. The last metric is an extension of the Hartle-Thorne metric that is important for obtaining internal models of compact objects perturbatively. The electromagnetic field is calculated using Cartan forms for locally non-rotating observers. These spacetimes are relevant for inferring properties of compact objects from astrophysical observations. Furthermore, the numerical implementations of these metrics are straightforward, making them versatile for simulating potential astrophysical applications.
