Resurgence of human coronavirus OC43 at a long-term care facility during the coronavirus disease 2019 (COVID-19) pandemic: Outbreak investigation.

The incidence of seasonal infections due to respiratory viruses other than severe acute respiratory coronavirus virus 2 (SARS-CoV-2) has declined due to heightened public infection prevention measures against coronavirus disease 2019 (COVID-19). We describe an outbreak of human coronavirus OC43 infection that occurred at a long-term care facility and whose clinical features were indistinguishable from COVID-19.

Did kindergarteners who experienced the Great East Japan earthquake as infants develop traumatic symptoms? Series of questionnaire-based cross-sectional surveys: A concise and informative title: traumatic symptoms of kindergarteners who experienced disasters as infants.

BACKGROUND: The Great East Japan Earthquake (GEJE) and tsunami of March 11, 2011 left behind many survivors, including children. This study aimed to assess changes in traumatic symptoms with time among kindergarteners who experienced GEJE as infants and to discuss the relationship between these symptoms and the disaster experience. METHODS: The 15-item Post-Traumatic Stress Symptoms for Children (PTSSC-15) questionnaire were distributed to the parents of kindergarteners (children aged 4-5 years) at 8, 20, 30, and 42 months after GEJE. Questionnaires regarding environmental damage conditions affecting the children were distributed to teachers 8 months after the tsunami. RESULTS: The number of kindergarteners was 262, 255, 236, and 202 at 8, 20, 30, and 42 months after the disaster. The PTSSC-15 total score was not different between kindergartners with and without environmental damage conditions. After 8 and 20 months, the PTSSC-15 total score of children who usually ate breakfast was significantly higher than that of children who did not. Moreover, after 30 and 42 months, the PTSSC-15 total score of kindergarteners who usually ate breakfast was not significantly higher than that of kindergarteners who did not. CONCLUSIONS: The traumatic symptoms of kindergarteners were not related to disaster experiences.

Sleep duration among children 8 months after the 2011 Japan earthquake and tsunami.

BACKGROUND: To elucidate relationships between disaster damage conditions and sleep duration among children who survived the 2011 Japan earthquake and tsunami. METHODS: The subjects comprised 12,524 children in kindergartens, elementary schools, and junior high schools in Ishinomaki City, Miyagi Prefecture, Japan. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a sleep questionnaire were distributed to them. A questionnaire regarding disaster damage conditions of the children's homes was distributed to their teachers. Of 12,524, an effective response was obtained from 11,692 (93.3%). RESULTS: Relationships between sleep duration and traumatic symptoms were displayed low correlations. Children with house damage and/or evacuation experiences slept for a significantly shorter time than children without these experiences. CONCLUSION: It is critical not only to examine traumatic symptoms in children but also to collect sleep duration and disaster damage conditions following natural disasters.

Relationships between traumatic symptoms and environmental damage conditions among children 8 months after the 2011 Japan earthquake and tsunami.

BACKGROUND: To evaluate relationships between traumatic symptoms and environmental damage conditions among children who survived the 2011 Great East Japan Earthquake and Tsunami. METHODS: The subjects were 12,524 children in kindergartens, elementary schools, and junior high schools in Ishinomaki City, Miyagi Prefecture, Japan. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, was distributed to the children and a questionnaire regarding environmental damage conditions affecting the children was distributed to their teachers. Of 12,524 questionnaires distributed, an effective response was obtained from 11,692 (93.3%). RESULTS: The PTSSC-15 score was significantly higher in females than in males among 4(th) to 6(th) grade students in elementary schools and among junior high school students. In terms of traumatic symptoms and environmental damage conditions, with the exception of kindergartners, children who had their houses damaged or experienced separation from family members had a significantly higher PTSSC-15 score than children who did not experience environmental damage. Except for kindergartners and 4(th)- to 6(th)-grade elementary school students, children who experienced evacuation had a significantly higher PTSSC-15 score. CONCLUSIONS: This study demonstrated relationships between traumatic symptoms and environmental damage conditions in children who had suffered from the disaster. Factors examined in studying the relationship between environmental damage conditions and traumatic symptoms were gender, age, house damage, evacuation experience, and bereavement experience. It was critical not only to examine the traumatic symptoms of the children but also to collect accurate information about environmental damage conditions.

[A case of spindle cell carcinoma of the breast, in which irinotecan was effective against respiratory failure due to pulmonary metastases].

We present our experience with chemotherapy using irinotecan for lung metastases of spindle cell carcinoma of the breast. The patient is a 50-year-old female, who consulted our hospital due to a large breast tumor about 7 cm in diameter. Although computed tomography revealed invasion to the chest wall, no distant metastases were confirmed. Chemotherapy (FEC100 followed by paclitaxel) was not effective for down-staging. To improve her quality of life, standard radical mastectomy with combined partial resection of the chest wall was performed. The tumor was histologically diagnosed as spindle cell carcinoma. After the operation, multiple lung metastases appeared, and she had severe dyspnea. Thereafter irinotecan was administered. One week after the administration, metastatic lesions were reduced so that her dyspnea was remarkably relieved. The patient continued to receive irinotecan weekly until she died on the 49th day of treatment with irinotecan.
