We describe an autochthonous case of Rickettsia slovaca infection in a man 35 years of age from Russia who had tickborne lymphadenopathy. We used ELISA and quantitative PCR testing to further identify DNA and confirm diagnosis. Physicians in Russia should consider similar diseases in differential diagnoses after tick bites.

The article presents a clinical example of Guillain-Barre syndrome with a predominant involvement of cranial nerves, which developed after COVID-19. Comprehensive clinical and laboratory diagnostics, including examination of cerebrospinal fluid, electromyography, examination for possible etiological infectious agents, was carried out. A course of pathogenetic therapy was used in the form of plasmapheresis sessions, supportive therapy. A good clinical effect was obtained. To this moment, only a few cases of the development of Guillain-Barré syndrome after a new coronavirus infection have been described. The peculiarity of our case is the development of a clinical picture of insufficiency of predominantly cranial nerves with subclinical involvement of the nerves of the extremities.

Background: A number of factors can lead to differences in infectious disease morbidity in children versus adults after a trip abroad. We aimed to investigate the epidemiological and etiological features of infectious diseases in children after international travel., Methods: we analyzed the medical records of 2135 patients (416 children) who were hospitalized during the period 2009-2017 after return from international travel., Results: Hospitalized children were under the age of 1 year in 8.7% of cases, 1-3 years - 39.4%, 4-6 years - 17.3%, 7-11 years - 16.8%, 12-17 years - 17.8%. Children were hospitalized after visiting the following main destinations: Turkey (15%), Egypt (12%), Central Asia microregion [11%] and Thailand (9%). Hospitalizations among children occurred mainly in summer (38.0%; CI 33.3-42.4). In adults there were no significant seasonal differences. Children were more likely to have acute diarrhea (18.3 vs 11.1%), acute respiratory tract infections (51.2 vs 41.2%) and enterovirus infections (8.2 vs 3.1%). Among the non-endemic infections for Russia, 8 children were diagnosed with dengue fever, 1 with typhoid, 1 with malaria, and 1 with wild-poliovirus excretion., Conclusion: children were mainly hospitalized during summer. Among hospitalized children, almost half was under 3 years old. In children acute respiratory infection and intestinal infections predominated, while in adults, vector-borne diseases were more frequently observed., (Copyright © 2019 Elsevier Ltd.
