RESUMO
Sialadenitis has rarely been reported in patients with infectious mononucleosis (IM). Our patient was a 22-year-old man who presented with bilateral swelling of the parotid and submandibular glands, a fever, malaise, and splenomegaly. Laboratory tests revealed an increased percentage of atypical lymphocytes in the leukocyte fraction. Serological testing for antibodies against Epstein-Barr virus (EBV) revealed an acute infection pattern. The patient was diagnosed with sialadenitis associated with IM caused by EBV infection. With symptomatic treatment, the salivary gland swelling completely resolved within a week. This case suggests that EBV-induced IM should be included in the differential diagnosis of diffuse sialadenitis with elevated atypical lymphocyte counts.

A 21-year-old man presented with an acute onset of bilateral throbbing headache, left ear pain, tinnitus, and fever. There was no skin rash on his face. Otoscopy revealed hyperemia and exudate over the left tympanic membrane. The swab culture of the exudate grew methicillin-sensitive Staphylococcus aureus, and the patient was diagnosed as acute otitis media. Hearing loss and ipsilateral facial paralysis developed on hospital day 4. Despite the absence of typical bullous lesions, serology testing and polymerase chain reaction of the otic exudate for varicella-zoster virus were positive. The patient was finally diagnosed as zoster sine herpete.

Objective In fever clinics screening coronavirus disease (COVID-19), there could be patients with life-threatening diseases that physicians should not overlook. We exploratorily investigated the final diagnosis among non-COVID-19 hospitalized patients who visited the fever clinic. Methods This was a retrospective, observational, and single-centered study conducted in the National Center for Global Health and Medicine (NCGM), Tokyo, Japan. We conducted a retrospective chart review of patients who visited the fever clinic in the NCGM from 11 March 2020 to 24 April 2020. Patients Patients who met the following clinical criteria visited the fever clinic in the NCGM: (1) body temperature >37.5°C, (2) any symptoms consistent with COVID-19 or (3) referral from local healthcare facilities. In the fever clinic, all patients who met the above criteria had severe acute respiratory syndrome coronavirus 2 polymerase chain reaction test with nasopharyngeal swab specimens. Patients with severe symptoms or an unstable condition were sent to an outpatient clinic for infectious diseases for further evaluation and treatment. Results Among 1,470 patients who visited the fever clinic, 84 patients were hospitalized, and 45 of them were diagnosed as having COVID-19. Among the remaining 39 non-COVID-19 patients, there were nine patients with life-threatening diseases. The life-threatening diseases included acute heart failure, septic shock, pneumocystis pneumonia, peritonsillar abscess, and necrotizing fasciitis. Conclusion Physicians should evaluate each patient carefully while considering other life-threatening conditions even in such a COVID-19 pandemic era.

Continuous use of wearable robots can cause skin injuries beneath the cuffs of robots. To prevent such injuries, understanding the contact behavior of the cuff is important. Thus far, this contact behavior has not been studied because of the difficulty involved in measuring the slippage under the cuff. In this study, for the first time, the relative displacement, slippage, and interaction force and moment at the thigh cuff of a robot during sit-to-stand motion were measured using an instrumented cuff, which was developed for this purpose. The results indicated that the slippage and relative displacement under the cuff was uneven because of the rotation of the cuff, which suggests that the risk of skin injuries is different at different positions. Especially, the skin closer to the hip showed larger dynamism, with a maximum slippage of approximately 10 mm and a displacement of 20 mm during motion. Another important phenomenon was the individual difference among subjects. During motion, the interaction force, moment, and slippage of some subjects suddenly increased. Such behavior results in stress concentration, which increases the risk of skin injuries. These analyses are intended to understand how skin injuries are caused and to design measures to prevent such injuries.
