Piezoelectric surgery is an innovative and promising surgical technique in the temporal bone. PEI appears to enable safer and more precise bone removal in close proximity to soft tissue when compared to the drill. The slower bone removal and cost factors represent current limitations to its wider use in ear surgery.

Diagnosis of pregnancy associated cancer is especially challenging because tumor symptoms may be masked by normal physiologic changes of pregnancy. The burden of care for both mother and child goes well beyond factual medical information. Balancing the potential risks and benefits to the mother and fetus necessitates a superior level of knowledge and expertise that includes epidemiology, pathophysiology, ionizing radiation and teratogenesis, risks and benefits of various imaging modalities, oncology, and radiotherapy, and other areas. Radiologists are an integral part of a multidisciplinary team that shares responsibility for selection of safe and effective diagnosis and management. Throughout the course of treatment, counseling and support are of paramount importance to the patient and her family. A compassionate culture of care bolsters the effectiveness of the care team to inform, counsel, and engage with the patient to achieve optimal outcomes. This special section of Abdominal Radiology is meant to offer insights for diagnostic imaging and its role in personalized management of this most serious and challenging condition. This article will provide an overview of imaging cancer in pregnancy and detail the relevant epidemiology.
To develop and validate a computed tomography (CT) radiomics nomogram from multicentre datasets for preoperative prediction of perineural invasion (PNI) in colorectal cancer.

A total of 299 patients with histologically confirmed colorectal cancer from three hospitals were enrolled in this retrospective study. Radiomic features were extracted from the whole tumour volume. The least absolute shrinkage and selection operator logistic regression was applied for feature selection and radiomics signature construction. Finally, a radiomics nomogram combining the radiomics score and clinical predictors was established. The receiver operating characteristic curve and decision curve analysis (DCA) were used to evaluate the predictive performance of the radiomics nomogram in the training cohort, internal validation and external validation cohorts.

Twelve radiomics features extracted from the whole tumour volume were used to construct the radiomics model. The area under the curve (AUC) values of the radiomics model in the training cohort, internal validation cohort, external validation cohort 1, and external validation cohort 2 were 0.82 (0.75-0.90), 0.77 (0.62-0.92), 0.71 (0.56-0.85), and 0.73 (0.60-0.85), respectively. The nomogram, which combined the radiomics score with T category and N category by CT, yielded better performance in the training cohort (AUC = 0.88), internal validation cohort (AUC = 0.80), external validation cohort 1 (AUC = 0.75), and external validation cohort 2 (AUC = 0.76). DCA confirmed the clinical utility of the nomogram.

The CT-based radiomics nomogram has the potential to accurately predict PNI in patients with colorectal cancer.

Sixty adult SARS Cov-2 PCR-positive patients (22 mild, 25 moderate, and 13 severe) and 50 healthy controls were included in this study. The serum levels of CHI3L1, IL-1-alpha, and IL-6 for all study participants were measured by protein-specific ELISAs. https://www.selleckchem.com/products/ti17.html Mean serum CHI3L1 levels in patients with severe disease (7,185.5 ± 1,109.4) were significantly higher than in the moderate (3,977.4 ± 1,260.3), mild (1,379.5 ± 598.8), and control (329.5 ± 128.4) groups (P = 0.001). There was no difference in IL-1-alpha levels between the patient and control groups (P = 0.083). IL-6 levels differed significantly, being lowest in the control group (35.9 ± 13.7), 89.1 ± 23.4 in the mild group, 156.2 ± 29.6 in the moderate group, and the highest in the severe group (214.9 ± 28.1) (P = 0.001). A strong significant correlation was found between disease severity and serum IL-6 and CHI3L1 values (r = 0.894 and r = 0.905, respectively, and P  less then  0.001 for both). Serum CHI3L1 and IL-6 levels exhibited a linear correlation with the clinical course of COVID-19 infection. These results indicate that inhibitors of IL-6 and/or CHI3L1 may provide useful treatments for COVID-19.The previous report partially brought to light history of publishing of "The letters of S. P. Botkin from Bulgaria 1877". The original letters were abroad for many years and they were returned to the USSR in 1974 by grandchildren of S. P. Botkin, S. P. Chekhov and D. P. Chekhov, who resided in France. The circumstances of handing over of the letters to the N. A. Semashko Institute of Health Organization and Social Hygiene are presented. The letters have not been republished for 130 years, but their historical, moral and educational significance remains actual and nowadays. The modern edition of the complete manuscript, along with introductory article and detailed scientific commentary, will become a significant contribution to representation of biography of S.P Botkin, to supplementation of written sources about the Russian-Turkish war of 1877-1878, and to comprehension of centuries-old Middle Eastern geopolitics of Russia.In the XIX century, process of joining of the North-East lands to the Russian empire was completed. The syphilis that spread in XVIII-XIX centuries stroke indigenous population of the Eastern Siberia and out-migrants from other territories. The article attempts to highlight little-studied aspects of organization of syphilitic hospitals and medical care of newly come population and non-Russian communities in northern Okrugs of Yakutsk, Kamchatka and Primorye areas of Eastern Siberia. On the basis of archive materials, the investigation was applied to the most important components of organization of medical care of patients with syphilis the organization of syphilitic hospitals, history of correspondence and decision-making on funding sources, building of yurts, choice of buildings for hospitals, delivery of medications, invitation and appointment of physicians, medical assistants and healers to assist population with medical care. The role of the Irkutsk Prikaz of Public Charity and the Irkutsk Medical Board in this process is noted. The establishment of syphilitic hospitals in outlying territories of Yakutia, Kamchatka and Primorye was the most important onset of struggle with syphilis epidemic in population.The article considers problems of organization of medical care at railroad transport in Russia at beginning of XX century. The implemented historical reconstruction was based on materials of section of railroad medicine of Congresses of the Society of Russian Physicians in memory of N. I. Pirogov. The issues are analyzed concerning legal basis of railroad medicine, duties of services and position of railroad physicians, principles of organization of medical sanitary unit and medical care of passengers, organization of sanitary supervision of status of railroad workers and ensuring safety on railroad transport.The researchers, in series of articles, analyze significance of the default of 1998 for both pharmaceutical industry and participants of pharmaceutical market. The Report I presents results of investigation of corresponding economic and social aspects of issue.

In current conditions, an important moment is increasing medical activity of elderly population and old persons. The purpose of the study is to investigate social hygienic characteristics of medical activity and satisfaction with geriatric care of the elderly residents of Mongolia. The sociological survey of 726 residents of Mongolia older than able-bodied age, 75 out of which were in nursing homes, was carried out using specially designed questionnaire that included questions on assessing medical activity and satisfaction with geriatric care. The negative correlation was established between good assessment of one's own health and age of respondents. The study revealed that 90.9% of respondents noted presence of chronic pathology, but only 21.1% of them were registered in dispensary. In age group under 65 years, 75.8% of persons capable to serving themselves made up 75.8% and in age group 75 years and older only 48.1%. The analysis established that 50.2% of elderly and senile persons consulted geriatrician, while 48.3% of those who did not consult this specialist were unaware of its existence. The number of cases of respondents visiting geriatric doctor in place of their residence was higher in cities. The respondents who received geriatric medical care were completely satisfied with it in 52.7%. The causes of dissatisfaction with geriatric medical care in aimags (regions) were inattentive attitude of medical staff, low effectiveness of treatment and insufficient availability of free provision of medications. The identified social hygienic characteristics of medical activity and satisfaction with geriatric care of the elderly and senile residents of Mongolia should be taken into account in developing measures to improve this type of care in Mongolia.The article discusses health saving technologies in context of education resources for children with disabilities.
