ABSTRACT

BACKGROUND: The carriage prevalence of pneumococcus among community-dwelling older adults is not fully understood, especially in superaged societies. Our purpose was to elucidate the carriage prevalence of pneumococcus in the upper respiratory tract among Japanese community-dwelling adults aged ≥65 years. METHODS: We conducted a cross-sectional study of generally healthy community-dwelling adults aged ≥65 years in Nagasaki city, Japan. Demographic and clinical data and nasopharyngeal, oropharyngeal and saliva samples were collected from February 21st, 2018, to December 17th, 2018. The specimens were tested by culture and molecular methods. RESULTS: Among a total of 504 enrolled participants, none were positive for pneumococcus by culture, and 22 were positive by PCR. The overall carriage prevalence was 4.4% (95% CI: 2.8-6.5%). The prevalence was highest in saliva samples, followed by oropharyngeal and nasopharyngeal samples. No demographic characteristics were associated with carriage prevalence, including age (4.7% among participants aged 65-74 years and 4.1% among those 75 years and older). Among the pneumococcal-positive participants, 18.2% were PCV13-covered serotypes. CONCLUSIONS: Our data suggest a low carriage prevalence of S. pneumoniae among community-dwelling older people in Japan.

ABSTRACT

Immunoglobulin G4 (IgG4)-related diseases have been reported to be systemic diseases characterized by elevation of serum IgG4 concentration and infiltration of IgG4-positive plasma cells within the target organ. However, the involvement of coronary artery is very rare. Here, we report a 62-year-old man with mass lesions surrounding coronary artery and abdominal aorta associated with IgG4-related disease diagnosed by a needle biopsy of the mass lesion surrounding the coronary artery using echocardiography and computed tomography. After we started to treat the patient with prednisolone, his serum IgG4 level decreased, and the mass lesions of coronary and abdominal artery were markedly reduced in size after 4 months. In conclusion, IgG4-related disease should be considered in addition to tumors such as malignant lymphoma when mass lesions surrounding coronary artery are detected.

ABSTRACT

A 71-year-old Japanese woman presented with a chief complaint of throbbing sensations in the abdomen. When she was 16 years old, she was exposed to atomic radiation since she was 1.2 km away from the drop zone of the Nagasaki atomic bomb. Abdominal CT performed at the age of 61 revealed the presence of localized calcification below the renal artery, together with abdominal aortic aneurysms measuring 4.9 cm in maximum diameter. Since the abdominal aortic aneurysms enlarged in May 2000, the patient was admitted to our department for further examinations and treatment on July 7. Although the patient did not complain of thoracic symptoms, cardiac catheterization revealed the presence of multiple coronary artery aneurysms and severe stenosis in the main trunk of the left coronary artery and proximal regions of the right coronary artery, together with a complicated collateral circulation course. Coronary artery aneurysms were localized similar to the abdominal aortic aneurysms, and were complicated by severe calcification and obstructive lesions. Coronary arterial bypass grafting was performed after the severity of the coronary artery aneurysms was morphologically evaluated. The course of the abdominal aortic aneurysms was followed without surgical treatment. Although the etiology of the aneurysm formation in this patient was investigated, it remained unclear.
