Перикапсулярная блокада тазобедренного сустава после его эндопротезирования

We report a case of postoperative pain relief in a patient after total cement arthroplasty of the right hip joint in the early postoperative period. Pericapsular nerve group block (PENG-block) of the hip joint was suggested to provide adequate pain relief and reduce the risk of postoperative complications. This clinical case shows an example of effective pain relief in a patient in the early postoperative period after reconstructive plastic restoration of the right hip joint, performed for a fracture of the femoral neck. Severe pain syndrome, restriction of movements, forced position and volume of surgical intervention are risk factors for the development of thromboembolic complications. According to the literature, the incidence of thromboembolic complications after total cemented hip arthroplasty varies from 9.3 to 20.7%. Our observation indicates that pericapsular block of the hip joint is an effective method of pain relief in the early postoperative period after total hip replacement.Представлено клиническое наблюдение послеоперационного обезболивания пациентки после тотального цементного эндопротезирования правого тазобедренного сустава в раннем послеоперационном периоде.Предложена перикапсулярная блокада (Pericapsular nerve group block, PENG-block) тазобедренного сустава с целью адекватного обезболивания и снижения риска послеоперационных осложнений.Данное клиническое наблюдение показывает пример эффективного обезболивания пациентки в раннем послеоперационном периоде после реконструктивно-пластического восстановления правого тазобедренного сустава, выполненного по поводу перелома шейки бедренной кости. Выраженный болевой синдром, ограничение движений, вынужденное положение и объем оперативного вмешательства являются факторами риска развития тромбоэмболических осложнений. По данным литературы, частота развития тромбоэмболических осложнений после тотального цементного эндопротезирования тазобедренного сустава варьирует в пределах от 9,3 до 20,7%. Наше наблюдение свидетельствует, что перикапсулярная блокада тазобедренного сустава является эффективным методом обезболивания в раннем послеоперационном периоде после тотального протезирования тазобедренного сустава

Polaritonic molecular clock for all-optical ultrafast imaging of wavepacket dynamics without probe pulses

Conventional approaches to probing ultrafast molecular dynamics rely on the use of synchronized laser pulses with a well-defined time delay. Typically, a pump pulse excites a molecular wavepacket. A subsequent probe pulse can then dissociate or ionize the molecule, and measurement of the molecular fragments provides information about where the wavepacket was for each time delay. Here, we propose to exploit the ultrafast nuclear-position-dependent emission obtained due to large light–matter coupling in plasmonic nanocavities to image wavepacket dynamics using only a single pump pulse. We show that the time-resolved emission from the cavity provides information about when the wavepacket passes a given region in nuclear configuration space. This approach can image both cavity-modified dynamics on polaritonic (hybrid light–matter) potentials in the strong light–matter coupling regime and bare-molecule dynamics in the intermediate coupling regime of large Purcell enhancements, and provides a route towards ultrafast molecular spectroscopy with plasmonic nanocavitiesThis work has been funded by the European Research Council grant ERC-2016-STG-714870 and the Spanish Ministry for Science, Innovation, and Universities—AEI grants RTI2018-099737-B-I00, PCI2018-093145 (through the QuantERA program of the European Commission), and CEX2018-000805-M (through the María de Maeztu program for Units of Excellence in R&D

Magic Curiosity Arousing Tricks (MagicCATs): a novel stimulus collection to induce epistemic emotions

There has been considerable interest in empirical research on epistemic emotions, i.e. emotions related to knowledge-generating qualities of cognitive tasks and activities such as curiosity, interest, and surprise. One big challenge when studying epistemic emotions is systematically inducting these emotions in restricted experimental settings. The current study created a novel stimulus set called Magic Curiosity Arousing Tricks (MagicCATs): a collection of 166 short magic trick video clips that aim to induce a variety of epistemic emotions. MagicCATs are available for research, and can be used in a variety of ways to examine epistemic emotions. Rating data also supports that the magic tricks elicit a variety of epistemic emotions with sufficient inter-stimulus variability, demonstrating good psychometric properties for their use in psychological experiments

ALGORITHM OF DIAGNOSIS AND TREATMENT OF PATIENTS WITH PELVIC TRAUMA COMPLICATED WITH RETROPERITONEAL HEMORRHAGE

Introduction. Despite great diagnostic and therapeutic advances, the amount of complications and mortality rate in patients with retroperitoneal hemorrhage associated with pelvic trauma remains high. The primary aim of treatment in such patients is early recognition and arrest of bleeding source and intensive therapy. Thus, the development of diagnostic and treatment algorithm is important for improvement the results of treatment of patients with pelvic trauma complicated by retroperitoneal hemorrhage.The aim of the study is to evaluate the effectiveness of the developed algorithm for diagnosis and treatment of patients with pelvic trauma complicated with retroperitoneal hemorrhage.Material and Methods. Retrospective comparative analysis was performed in 374 patients with pelvic fractures complicated with retroperitoneal hemorrhage who were admitted to our hospital from 2007 to 2015. The study group consisted of 164 patients who were treated according to the new algorithm for diagnosis and treatment. The control group consisted of 210 patients who were not treated with the developed algorithm.Results. Clinical use of the developed algorithm led to reduction in mortality from 12.2 to 9.7%. The number of common complications decreased from 41.3 to 25.0%, and local complications decreased from 28.6 to 18.9%. The time of patients’ activation after the definitive fixation of pelvis reduced from 17.5 to 7.6 days. The average hospital stay decreased from 46.1 to 35.2 days.Conclusion. The developed diagnostic and treatment algorithm helped reduce mortality rate, the number of general and local complications in patients with pelvic trauma complicated by retroperitoneal hemorrhage as well as the duration of bed rest and hospital stay

Shoulder Dislocations

ABSTRACT. Shoulder dislocations are among the most common injuries and occupy the first place among all dislocations of limbs. Currently, the conventional approach to the treatment and diagnosis of this pathology is preserved. The closed reduction is performed under local anesthesia, the limb is immobilized with a bandage sling. There is no single opinion on the period of immobilization. Common indications for surgical treatment are unreduced, habitual and open shoulder dislocations. The preference is given to operations with the restoration of anatomy, while at the end of the last century, techniques were often used to limit the amplitude of movements in the shoulder joint. Currently unphysiological reconstruction methods are not favourable, since they violate the normal biomechanics of the shoulder joint and do not directly affect the pathological substrate of damage. Outcomes after arthroscopic options for operations are not inferior to those after open interventions. This article provides an overview of clinical and radiological methods for examining patients and treatment options for this pathology
