Ankylosing spondylitis is chronic, progressive, inflammatory disease involving the spine, peripheral joints, and periarticular structures. Cardiac abnormalities associated with ankylosing spondylitis are well recognized, but a case with DDD pacemaker implantation for complete atrioventricular block and aortic valve replacement for aortic regurgitation has not been previously reported. We report a case of a 66-year-old man with ankylosing spondylitis who was successfully treated by DDD pacemaker implantation for complete atrioventricular block and aortic valve replacement for severe aortic regurgitation.

In Japan, fine-needle aspiration (FNA) cytology is the most important diagnostic modality for triaging patients with thyroid nodules. A clinician (endocrinologist, endocrine surgeon, or head and neck surgeon) generally performs FNA cytology at the outpatient clinic, and ultrasound (US)-guided FNA is widespread because US is extremely common and most clinicians are familiar with it. Although almost all FNA thyroid samples are examined by certified cytopathologists and pathologists, some clinicians assess cytological specimens themselves. In Japan, there are two clinical guidelines regarding the management of thyroid nodules. One is the General Rules for the Description of Thyroid Cancer (GRDTC) published by the Japanese Society of Thyroid Surgery (JSTS) in 2005, and the other is the national reporting system for thyroid FNA cytology published by the Japan Thyroid Association in 2013 (Japanese system). Although the Bethesda System for Reporting Thyroid Cytopathology (Bethesda system) is rarely used in Japan, both the GRDTC and Japanese system tried to incorporate the Bethesda system so that the cytological diagnoses would be compatible with each other. The essential point of the Japanese system is stratification of follicular neoplasm (FN) into three subgroups based on cytological features in order to reduce unnecessary diagnostic thyroidectomy, and this system has been successful in stratifying the risk of malignancy in FN patients at several high-volume thyroid surgery centers. In Japan, the measurement of thyroglobulin and/or calcitonin in FNA needle washings is often used as an adjunct for diagnosis of possible cervical lymph node metastasis when FNA cytology is performed.

We conducted a seroepidemiological study in a northern Japanese prefecture where the incidence of identified COVID-19 cases was low. In June 2020, residual sera from 1009 outpatients were tested for antibody to SARS-CoV-2 by electrochemiluminescence immunoassay. Five specimens (0.5%) tested positive, suggesting low prevalence of SARS-CoV-2 infections in this population.
