Features of X-ray diagnostics of Hamman’s syndrome associated with new coronavirus infection. Clinical observation

The results of our study show that the respondent’s perception of large-scale social changes associated with the pandemic of the new coronavirus infection in the Kyrgyz Republic has a number of features. A sufficient level of awareness of the respondents about the symptoms of the disease, the ways of transmission of the virus, and measures to prevent the spread of infection are combined with an underestimation of the situation (17.2%). The majority (66.6%) of the respondents lived in Bishkek. The survey was held among 247 people, most of whom were women (57.3%) and young people (35.9±14.9 years). Every fourth participant in the study is a chronic tobacco smoker (24%). Less than half (47.3%) of the respondents were engaged in intellectual work. Among the respondents, the most common symptoms of COVID-19 were loss of taste or smell, fever, headache, muscle ache, cough, sore throat. Every third (28.4%) respondent was referred to an X-ray, CT scan. PCR and ELISA studies were carried out, respectively, by 22.5% and 10.9%.

Abstract: Internal resorption is an asymptomatic condition in teeth seen with past history of injury. In the crown it has a clinical observation of pink mark. It is diagnosed by chance on an x-ray examination. Primal detection and resorption treatment improves prognosis of the condition. Resorption can be broadly classified into normal physiological or pathological process associated with extensive damage to hard structures of tooth such as dentin, cementum and bone. Proper diagnosis of resorption and differentiation of resorption from internal and external resorption by radiographic presentation and the correct diagnosis and treatment planning improves the prognosis of the condition. Untreated cases will cause loss or early exfoliation of the afflicted tooth [1].

Current trials are underway to design chemotherapy regimens that include bedaquiline to treat children with rifampicin and isoniazid resistant mycobacterium tuberculosis. This clinical observation is interesting from the viewpoint of experience of the potential effective and safe use of the new anti-tuberculosis drug bedaquiline (Sirturo) in children under 12 years of age, as the publications of clinical trials of the drug use in children is limited. The female patient was diagnosed with primary tuberculosis complex complicated by infusional pleurisy based on the epidemiological anamnesis (family contact with tuberculosis patients), immunodiagnostic tests – a positive ATR-test result (Diaskin-test), pathological changes in the lung tissue and intrathoracic lymph nodes found on the chest CT scans. The diagnosis was confirmed by detection of MBT in pleural effusion by PCR and liquid culture method (BACTEC MGIT-960), which are resistant to isoniazid and rifampicin (multidrug resistance, MDR). The girl was enrolled in a clinical trial and treated according to chemotherapy regimen IV including a new anti-tuberculosis drug, which she received for 6 months. There was a positive clinical and X-ray dynamics of the tuberculosis process with minimal residual changes throughout the entire course of chemotherapy followed by confirmed clinical cure of TB (after 24-month follow-up). Based on the example of this clinical observation, it can be concluded that bedaquiline is safe and showed good clinical efficacy in the chemotherapy regimen to treat MDR MBT in children under 12 years of age.

New Diagnosis

Abstract To speed up the discovery of COVID-19 disease mechanisms, this research developed a new diagnosis platform using a deep convolutional neural network (CNN) that is able to assist radiologists with diagnosis by distinguishing COVID-19 pneumonia from non-COVID-19 pneumonia in patients at Middlemore Hospital based on chest X-ray classification and analysis. Such a tool can save time in interpreting chest X-rays and increase the accuracy and thereby enhance our medical capacity for the detection and diagnosis of COVID-19. The research idea is that a set of X-ray medical lung images (which include normal, infected by bacteria, infected by virus including COVID-19) were used to train a deep CNN that can distinguish between the noise and the useful information and then uses this training to interpret new images by recognizing patterns that indicate certain diseases such as coronavirus infection in the individual images. The supervised learning method is used as the process of learning from the training dataset and can be thought of as a doctor supervising the learning process. It becomes more accurate as the number of analyzed images grows. In this way, it imitates the training for a doctor, but the theory is that since it is capable of learning from a far larger set of images than any human, it can have the potential of being more accurate.

Coronavirus Infection

Background: The year 2020 will remain in history as a challenge for the humanity due to the pandemic situation caused by the Coronavirus – COVID-19 disease. The virus spread rapidly throughout the world, affecting people of all ages including children. Objectives: The purpose of the research was to present the first case in Romania of a child infected with COVID-19, operated for associated surgical pathology. Materials and Methods: The case presented in this paper is a 6 years and 9 months old female child with COVID-19 infection admitted in the Clinic of Pediatric Surgery of Constanta Emergency County Hospital and operated for a peritonitis with appendicular abscess. In the last 7 days she presented transient abdominal pain with episodes of fever that referred to antipyretics. Results: From a surgical point of view, the case is ordinary, without possible redoubtable complications but the clinical picture was atypical due to coronavirus infection. The viral infection did not have a symptomatic history, as in most adult cases, but the lung x-ray showed infectious changes, which is why she was tested for potential COVID-19 infection, with a positive result. Conclusion: The case showed the clinical picture of atypical coronavirus infection in children. Viral infections in children have more abdominal tropism, with mesenteric lymphadenitis, which in some cases can lead to appendicular inflammation with secondary appendicitis. Undiagnosed in time, it can be complicated by peritonitis and any other type of appendicular infectious pathology.

Background. The article reports the number of examinations with stationary mammography systems, in outpatient screenings, as well as in a mobile mammography survey across the Sverdlovsk Region.Aim. A study of expedience and design of radiological breast check-ups (exemplified by mammography) for early cancer diagnosis under the COVID-19 pandemic situation.Materials and methods. A survey based at the Sverdlovsk Regional Oncology Dispensary’s Department of Diagnostic Radiology analysed the expedience and design of non-invasive diagnostic procedures in a case study of breast X-ray checkups (mammography) in the Sverdlovsk Region during 2019—2020. Th e survey used the Sverdlovsk Region population statistics on breast malignancy incidence for 2019—2020.Results. According to reports, the number of outpatient screening surveys significantly decreased in 2020 vs. 2019 due to the coronavirus pandemic and effective ban on screenings and medical check-ups. Th e mobile mammography screening numbers increased more than twice in 2020 vs. 2019.Discussion. Screening measures continued during the COVID-19 pandemic. Clinicians adhered to local guidelines, while fully complying with the recommendations to contain SARS-CoV-2 infection. Th e growth of mobile mammography screenings enabled completion of the annual check-up plan, however, the breast malignancy detection rate slightly dropped in 2020 compared to 2019.Conclusion. Mammography screenings at the Sverdlovsk Regional Oncology Dispensary in 2019--2020 demonstrate the expedience and good organisation of breast radiological check-ups (mammography) in Sverdlovsk Region. Accounting for the epidemiological state of coronavirus infection, a positive trend is evident towards growing examinations and improved breast malignancy detection, which lowers mortality accordingly among the female population of Sverdlovsk Region.

Foreign bodies of the respiratory tract and esophagus remain one of the pressing problems in medicine, which is associated with the possibility of developing complications that can end in death. We present our clinical observation that demonstrates the long-term presence of a large foreign body fixed in the area of the pharyngeal narrowing of the esophagus and extending into the larynx and the vestibule of the larynx. Patient T., 57 years old, went to the emergency department of the Karachay-Cherkessia Republican Clinical Hospital with complaints of severe sore throat, inability to swallow, excessive salivation, increased body temperature to 37,5 °C, difficulty breathing, mixed shortness of breath, which persist for 3 days. The examination revealed: the epiglottis is mobile, the mucous membrane of the larynx is hyperemic, edematous, with an abundance of saliva, at the level of the vestibular part of the larynx, in the area of the arytenoid cartilage and aryepiglottic folds, an irregular shape was visualized, with smooth edges, a thin, hard whitish plate. Computed tomography of the cervical spine: in the esophagus, at the level of C4-C5 vertebrae, a foreign body with a metallic density of +2900 hU units, elongated, irregular shape, measuring 2.2 by 3.3 cm, with perifocal air bubbles is determined. A preliminary diagnosis was made: Foreign body of the esophagus, laryngopharynx with a spread to the vestibule of the larynx. 3 days after the retention of the foreign body under intubation anesthesia, it is captured using forceps with serrated cups and removed during direct laryngoscopy. There were no complications during the manipulation. The combination of X-ray and endoscopic examinations with the help of innovative medical and diagnostic equipment made it possible to establish a diagnosis in a short time, choose the most effective treatment tactics and remove a foreign body through natural pathways.

Coronavirus Infection

AbstractCOVID-19 is posed as very infectious and deadly pneumonia type disease until recent time. Despite having lengthy testing time, RT-PCR is a proven testing methodology to detect coronavirus infection. Sometimes, it might give more false positive and false negative results than the desired rates. Therefore, to assist the traditional RT-PCR methodology for accurate clinical diagnosis, COVID-19 screening can be adopted with X-Ray and CT scan images of lung of an individual. This image based diagnosis will bring radical change in detecting coronavirus infection in human body with ease and having zero or near to zero false positives and false negatives rates. This paper reports a convolutional neural network (CNN) based multi-image augmentation technique for detecting COVID-19 in chest X-Ray and chest CT scan images of coronavirus suspected individuals. Multi-image augmentation makes use of discontinuity information obtained in the filtered images for increasing the number of effective examples for training the CNN model. With this approach, the proposed model exhibits higher classification accuracy around 95.38% and 98.97% for CT scan and X-Ray images respectively. CT scan images with multi-image augmentation achieves sensitivity of 94.78% and specificity of 95.98%, whereas X-Ray images with multi-image augmentation achieves sensitivity of 99.07% and specificity of 98.88%. Evaluation has been done on publicly available databases containing both chest X-Ray and CT scan images and the experimental results are also compared with ResNet-50 and VGG-16 models.
