While the COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a threat to public health as the number of cases and COVID-19-related deaths are increasing worldwide, the incidence of the virus infection is extremely low in Japan compared with many other countries. To explain this uncommon phenomenon, we investigated the prevalence of naturally occurring ("natural") antibodies, focusing on those of the secretory immunoglobulin A (sIgA) form, reactive with SARS-CoV-2 among Japanese people. One hundred and eighty healthy Japanese volunteers of a wide range of age who had been considered to be unexposed to SARS-CoV-2 participated in this study.

Epileptic Disord
December 2021
Eyelid myoclonia with absences (EMA) is an epileptic syndrome characterised by eyelid myoclonia with or without absences, eye closure-induced paroxysms, and photosensitivity. The relationship between EMA and epileptic negative myoclonus has not previously been reported. Herein, we describe a case of a 10-year-old girl who presented with eyelid myoclonia, eye closure-induced paroxysms, and photosensitivity, which was compatible with the diagnosis of EMA.

- Some studies indicate that sedative antihistamines might lengthen the duration of febrile seizures, but evidence remains mixed, leading to guidelines against their use.
- A new cross-sectional study was conducted to examine the link between febrile seizure duration and the use of sedative antihistamines, analyzing data from 426 patients with seizures.
- The findings showed no significant difference in seizure duration among patients using sedative antihistamines compared to those using nonsedative antihistamines or no antihistamines, suggesting that antihistamines may be safely considered for some patients with a history of febrile seizures.
Article Synopsis
- The study investigates how antimicrobial substances in children's saliva, specifically immunoglobulin A (IgA), lactoferrin, and lysozyme, are linked to their physical growth and lifestyle factors.
- Saliva samples from 90 children were analyzed for these substances, and results indicated that higher IgA flow rates were associated with increases in age, height, and weight.
- Additionally, a strong correlation was found between the flow rates of lactoferrin and lysozyme, and factors like sleep duration were also found to relate to lactoferrin levels.
We administered intramuscular injections of botulinum toxin type A (BTX-A) in 11 persons with cervical dystonia (CD) and muscular hypertonia (MH). All patients had severe motor and intellectual disabilities (SMID). Furthermore, in 10 patients, SMID was accompanied by respiratory problems and/or dysphagia.
