Timely Diagnosis

Background. The problem of timely diagnosis of complications of acute destructive pneumonia accompanied by pyofibrothorax remains relevant. The study was aimed to investigate the features of ultrasound diagnosis (ultrasound) of the condition of the visceral and parietal pleural lamina in acute destructive pneumonia in children at different stages of the disease. Materials and methods. In the departments of purulent surgery and pulmonology of the Regional Children’s Hospital of Dnipro for the period of 5 years, there were observed about 475 children aged from 1 to 17 years with pneumonia, purulent-destructive changes in the lungs and pleura. For analysis and further study, we choose a group of 50 patients of different age groups, who underwent ultrasound in real time without prior preparation of patients. The condition of the parietal and visceral pleural lamina at the different stages of diagnosis and treatment was studied. Results. A group of patients aged from 4 to 10 years was performed an ultrasound of the pleural cavities in real time without prior preparation on the paraspinal, scapular, axillary, midclavicular, and thoracic lines when admitted to the hospital and on the first day of treatment. Ultrasound was used to determine the structure and volume of free fluid as well as the condition of the parietal and visceral pleural lamina, their thickness, and other features. The use of ultrasound allowed diagnosing the early manifestations of pyofibrothorax and determining the condition of the parietal and visceral pleural lamina in the children with destructive pneumonia. Conclusion. Further improvement of the algorithm of ultrasound diagnosis of acute destructive pneumonia in children with pyofibrothorax will reduce radiation exposure to a child’s body, increase the efficiency of the development and improvement of treatment methods at the stages of pyofibrotorax, reduce the duration of inpatient treatment.

The Difference

Background—Several methods to reduce radiation exposure in the setting of coronary procedures are available on the market, and we previously showed that additional radiation shields reduce operator exposure during radial interventions. We set out to examine the efficacy of real-time personal dosimetry monitoring in a real-world setting of radial artery catheterization. Methods and Results—In an all-comer prospective, parallel study, consecutive coronary diagnostic and intervention procedures were performed with the use of standard radiation shield alone (control group) or with the addition of a real-time dosimetry monitoring system (Raysafe, Billdal, Sweden, monitoring group). The primary outcome was the difference in exposure of the primary operator among groups. Additional endpoints included patient, nurse, second operator exposure and fluoroscopy time. A total of 700 procedures were included in the analysis (n = 369 in the monitoring group). There were no differences among groups in patients’ body mass index (p = 0.232), type of procedure (intervention vs. diagnostic, p = 0.172), and patient sex (p = 0.784). Fluoroscopy time was shorter in the monitoring group (5.6 (5.1–6.2) min vs. 7.0 (6.1–7.7) min, p = 0.023). Radiation exposure was significantly lower in the monitoring group for the patient (135 (115–151) µSv vs. 208 (176–245) µSv, p < 0.0001) but not for the first operator (9 (7–11) µSv vs. 10 (8–11), p = 0.70) and the assistant (2 (1–2) µSv vs. 2 (1–2) µSv, p = 0.121). Conclusions—In clinical daily practice, the use of a real-time dosimetry monitoring device reduces patient radiation exposure and fluoroscopy time without an effect on operator radiation exposure.

Abstract Background Real-time dosimeters may create a relatively safer environment not only for the patient but also for the physician and the assistant as well. We propose the use of a real-time radiation measurement dosimeter having auditory feedback to reduce radiation exposure. Methods Radiation dose rates were measured for 30 fluoroscopy-guided puncturing procedures of femoral arteries in swine. Fifteen puncturing procedures were performed with real-time radiation measurement dosimeter having auditory feedback and other 15 were performed without auditory feedback dosimeter by an interventional cardiologist with 10 years of experience. Results The left body side of the operating physician (38%, p < 0.001) and assistant (25%, p < 0.001) was more exposed as compared to the right body side. Radiation dose rate to the left hand, left arm and left leg were reduced from 0.96 ± 0.10 to 0.79 ± 0.12 mSv/h (17% reduction, p < 0.001), from 0.11 ± 0.02 to 0.07 ± 0.01 mSv/h (36% reduction, p < 0.001) and from 0.22 ± 0.06 to 0.15 ± 0.02 mSv/h (31% reduction, p < 0.001) with the use of auditory feedback dosimeter, respectively. The mean fluoroscopic time was reduced from 4.8 ± 0.43 min to 4.2 ± 0.53 min (p < 0.001). The success rate of performing arterial puncturing was 100%. Conclusions The use of auditory feedback dosimeter resulted in reduction in effective dose. The sound beep alerted the physician from the danger of exposure, and this approach induced awareness and protective mindset to the operating physician and assistant.

Background: Chronic exposure to occupational ionising radiation is seen as one reason for elevated cancer prevalence. </P><P> Objective: The aim of this retrospective study was to evaluate radiation exposure of anaesthetists by real-time dosimetry. Methods: Data of 296 patients were analyzed. Ten types of trauma operation procedures including osteosynthesis of upper and lower extremity fractures and minimally invasive stabilisation of traumatic and osteoporotic vertebral fractures were accomplished. Evaluation was performed by an occupational dosimetry system, which visualises anaesthetists radiation exposure feedback compared to surgeons in real-time. Results: A significantly lower radiation exposure to anaesthetists compared to surgeons was observed in four types of operative procedures: Plate fixation of proximal humerus fractures, osteosynthesis of proximal femoral fractures, stabilisation of traumatic and osteoporotic vertebral fractures. In four types of operations (plate osteosynthesis of proximal humeral, distal radial and tibial fractures and intramedullary nailing of the clavicle), anaesthetists` amount of radiation exceeded one-third of the surgeons' exposure, especially if the C-arm tube was positioned close to the anaesthetists work station at the patients' head. Conclusion: By using the occupational radiation dose monitoring system, radiation exposure to anaesthetists was visualised in real-time during trauma operations. Radiation exposure of anaesthetists depends on the type of operation and the position of the C-arm. The system may help to increase anaesthetists` awareness concerning radiation exposure and to enhance compliance in using radiation protection techniques.

New Model

BACKGROUND Healthcare for older patients is a worldwide challenge for public health system. A new medical Internet system in healthcare which is a new model of telegeriatrics system has been established. The key innovation is the new telegeriatrics system was conducted jointly by general practitioners in the Community Health Service Center and specialists in university teaching hospital. Unlike the typical telemedicine that has been practiced in other countries, the new model provides a solution for the key issues in telemedicine where a doctor is unable to conduct a direct physical examination and the associated potential diagnostic error. OBJECTIVE This study is to introduce the operation mechanism of the new Telegeriatrics system and analyze healthcare demands of older patients in different age groups applying the new Telegeriatrics system. METHODS 472 older patients (aged≥60) were enrolled and divided into the young older group (aged 60 to 74), the old older group (aged 75 to 89) and the very old group (aged≥90) according to the age stratification of World Health Organization. Proportion of the top 10 diseases of older patients of different age groups was analyzed. RESULTS The process of older patients’ diagnosis and treatment made by specialist and general practitioners formed a closed loop. It ensures the timeliness and effectiveness of diagnosis and treatment of older patients. The treatment effect can be observed by general practitioners and specialist can adjust the treatment plan in time. In this study, it was found that older patients in different age groups have different healthcare demands. Coronary heart disease and type 2 diabetes mellitus were found to be the main diseases of the older patients and the young older patients as well as the old older patients applying Telegeriatrics. CONCLUSIONS The new telegeriatrics system can provide convenient and efficient healthcare services for older patients and overcome the disadvantage of currently used models of telegeriatrics. Older patients in different age groups have different medical care demands. Cardiovascular diseases and metabolic diseases have become the main diseases of the elderly applying the new Telegeriatrics system. Healthcare policy makers should invest more medical resources to the prevention of cardiovascular diseases and metabolic diseases in the elderly.
