Article Abstract
In a survey of pathologic agents in the wild animals of central Japan, we found a Hepatozoon sp. in the lungs of Japanese black bears in Fukui, Shiga, and Gifu Prefectures, Japan. Histopathologic examination of organs and tissues from the 18 bears inspected showed hepatozoonosis in all. Immature and mature meronts were found in all lobules and between alveoli, with a few found between pleura and in connective tissue. In the lungs, inflammatory cells were not found around meronts, merozoites, or tubercles made of macro-phages including zoites, but inflammatory cells were found around degenerating cells, zoites, and tubercles. A Hepatozoon sp. has not been reported as being detected in bears of any species before.

Background: Lung cancer surgery is associated with a high incidence of chronic postsurgical pain (CPSP), which necessitates long-term analgesic prescriptions. However, while essential for managing pain, these have shown various adverse effects. Current guidelines recommend using peripheral nerve blocks over epidural anaesthesia for perioperative analgesia in minimally invasive thoracic surgery (MITS).

Introduction: Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic interstitial pneumonia, which is characterised by progressive worsening of dyspnoea and lung function. Nintedanib treatment is recommended to slow IPF disease progression. The aim of this post-marketing surveillance (PMS) study was to evaluate the safety and effectiveness of nintedanib over 24 months in patients with IPF in a real-world setting in Japan.
