Septic cavernous sinus thrombosis in a patient with COVID-19.

The cavernous sinus is one of the dural venous sinuses which plays an important role in venous outflow from the brain and eye sockets and in the regulation of intracranial circulation. We report a case of septic cavernous sinus thrombosis in a female patient with COVID-19. The disease often results in alterations of blood rheology, thrombosis in different organs, and septic complications. This article aims to raise awareness of healthcare professionals about the characteristics of COVID-19 that might cause septic cavernous sinus thrombosis in patients with severe comorbidities. Laboratory testing revealed severe comorbidities, including diabetes mellitus and liver cirrhosis caused by hepatitis C. They manifested with an impaired protein production in the liver and coagulation disorders. Systemic effects of SARS-CoV-2 on the vascular endothelium aggravated preexisting coagulation disorders and led to hemorrhage into retrobulbar tissue and clinical signs of septic cavernous sinus thrombosis, including swelling of the eyelids, bilateral exophthalmos, and ophthalmoplegia, followed by necrosis of the facial skin.Copyright © 2022, Dynasty Publishing House.

Infectious Morbidity in Closed Long-Term Care Facilities in the «Pre-COVID Stage»

Relevance. Elderly people have become the fastest growing segment of the global population over the past few decades. The number of people over the working age in Russia, and with them citizens living in closed long-term care facilities (CLTFS), is growing. Residents of these organizations belong to the risk group, and CLTFS have a number of characteristics that turn these institutions into a unique environment for the spread of infectious diseases. Aims. To analyze the CLTFS residents infectious morbidity in the "pre-covid stage" (according to literature sources). A scientific review of research in Russian and English using information portals and platforms has been carried out eLIBRARY.ru, Web of Science, PubMed, Google Academy and Scopus for the period 1981-2022. The search was carried out by keywords. Information about the most frequent infectious diseases affecting residents of closed long-term care institutions was the criterion for inclusion in the sample of publications. Out of 16171 initially identified articles, 61 publications were selected after initial analysis. Conclusions. According to various estimates, the leading infectious diseases in CLTFS were: acute respiratory infections, pneumonia, urinary tract infections, skin and mucous infections, acute intestinal infections. The article describes pathogens and their prevalence in CLTFS including pathogens with multiple drug resistance (MDR), describes the resistance of bacteria to antimicrobial drugs formation problem in these organizations, as well as development of certain diseases risk factors. Studies conducted in various CLTFS in Europe, Russia, the USA, and Asia indicate a high prevalence of infectious diseases among their residents, high colonization of residents with antimicrobial-resistant pathogens, as well as the infection transmission probability from the CLTFS and its spread to other long-term care institutions and medical and preventive organizations. © 2023, Numikom.

Epidemic Outbreak of COVID-19 in Foreign Closed Long-Term Care Facilities

Objective. Of particular interest is the incidence of COVID-19 in closed groups, in institutions, in particular, in nursing homes, geriatric centers, veterans' homes and neuropsychiatric boarding schools. Methods. Analysis and description of COVID-19 foci in closed long-term care facilities was carried out using literature sources from the MEDLINE medical information database using the PubMed electronic search engine, using the search query CARE HOME OR NURSING HOME OR LONG-TERM CARE FACILITY AND COVID-19 AND OUTBREAK. The share of sick people as a percentage of the total number of residents and individual employees was considered only in those publications that described the outbreak of COVID-19 in a single institution. The absence of data on the number of hospitalizations and deaths, symptoms, and data on the time frame of the outbreak was not an exclusion criterion, but their presence was taken into account in the analysis. We selected mainly publications where people with a positive PCR test for SARS-CoV-2 RNA were considered to be ill with COVID-19. However, it is worth considering that the authors describe outbreaks during the first rise in the incidence of COVID-19 in the world, when there was a shortage of test systems for a new coronavirus infection. Results. An overview of the incidence of COVID-19 in the world in closed long-term care institutions is presented. It has been shown that residents of closed communities are elderly people with many concomitant diseases, in connection with which a severe course of COVID-19 and high mortality are often noted. Conclusion. Convictions about the need to strengthen the quality of anti-epidemic measures in closed long-term care institutions, which are at risk, are summarized. © Akimkin VG, et al.

Features of the course of influenza and its co-infection in children at the present stage

Influenza is an acute respiratory infection, mainly affecting the respiratory tract (often the trachea), with a tendency to develop symptoms rapidly and in most cases not requiring hospitalization. All acute respiratory infections are non-specific, with symptoms of intoxication, catarrhal symptoms (nasal congestion, rhinorrhoea, sore throat or pharyngeal discomfort), fever and cough. Improvement and widespread implementation of molecular methods to identify respiratory pathogens has led to the establish-ment of a higher frequency of co-infections. A literature review of the frequency of influenza co-infections is presented. Clinical cases of monoinfluenza and co-infections of influenza and respiratory syncytial infection are described, demonstrating the antag-onistic effect of the two viruses on the course of the disease. In the first case, the patient, 1 year 1 month old, was hospitalised with a fever of 39 ºC in a moderate condition. A nasopharyngeal swab showed RNA of influenza A virus by PCR and was diagnosed with influenza. In the second case, the patient, 2 years old, at the beginning of the disease complained of an increase in body temperature to 38.7 ºC, cough, and difficulty in nasal breathing. On admission, the patient was in moderate condition with a body temperature of 36.6 ºC, clear consciousness and well-being. On auscultation, breathing in the lungs was rigid, single moist rales, scattered on both sides. A nasopharyngeal swab showed RNA of influenza A virus and respiratory syncytial virus by PCR. A viral acute respiratory infection of combined etiology and acute bronchitis was diagnosed. In the third case, a 14-year-old patient presented with complaints of fever up to 39 ºC, headache, weakness, muscle pain, dry cough. The condition was of moderate severity. The diagnosis of influenza A was confirmed by a rapid test for influenza A/B/C. In the treatment and prevention of both monoinfection and co-infections of influenza and other viruses, these clinical examples demonstrate the effectiveness of osel-tamivir. These clinical examples highlight some key parameters: respiratory co-infections change the typical clinical picture of the disease, making it difficult to clinically diagnose the infection, highlighting laboratory diagnosis, which in turn facilitates rapid verification of the diagnosis and timely prescription of adequate therapy. © The Authors.

Mono- and mixed respiratory tract infections in children: Relevance of the problem during the COVID-19 pandemics

Acute respiratory infections are one of the most common infections in children worldwide. The implementation of novel highly accurate diagnostic methods demonstrated that a significant proportion of respiratory tract infections are caused by more than one pathogen (virus plus virus or virus plus bacterium). Most frequently, mixed infections are observed in young children, which, in addition to non-specificity of most clinical manifestations, necessitates pathogen identification in order to prevent inadequate use of antibiotics. © 2021, Dynasty Publishing House.
