Background There are no established guidelines regarding the optimal size of chest tubes following a bullectomy. While large chest tubes are commonly used after bullectomy, several studies have shown that pigtail catheters can be effectively employed for postoperative drainage in lung cancer surgery. This study aimed to compare the time to tube removal between an 8Fr pigtail catheter and a 24Fr chest tube after bullectomy to assess the non-inferiority of the 8Fr pigtail catheter.

Although myoepithelioma is defined as a benign tumour made up primarily of neoplastic myoepithelial cells, its actual histopathological characteristics are highly diverse. It can be considered a rare disease. The most common site of occurrence is the parotid gland, followed by the minor salivary glands of the palate.

In recent decades, the locally extinct sea otter (Enhydra lutris lutris) has been recolonizing the coast of eastern Hokkaido. Their diet includes benthic invertebrates such as bivalves, sea urchins, snails, and chitons. In the fall of 2021, a harmful algal bloom (HAB) of Karenia selliformis occurred across Hokkaido's northern and eastern coasts, leading to a massive mortality of sea urchins.

Article Synopsis
  • The article by Nie et al. discusses a rare case of extraskeletal osteosarcoma (EO) found in the sigmoid mesocolon, diagnosed through imaging and histopathology.
  • Diagnosing EO is complicated due to non-specific imaging properties and limited immunohistochemical markers, with SATB2 being a proposed but not highly specific option.
  • It's crucial to differentiate EO from other soft tissue sarcomas, like dedifferentiated liposarcoma, as some markers may overlap, complicating diagnosis.

This study measured the atmospheric concentration and deposition flux of radiocesium in Koriyama City, Fukushima Prefecture, Japan, from November 2011 to October 2014. The results show synchronous seasonal change in atmospheric concentration and deposition flux of radiocesium, which is high during winter to early spring and low during summer to autumn. These seasonal variations are similar to those observed in Fukushima City but differ from those in Namie Town, Fukushima Prefecture, comprising a larger contaminated forest area.
