The pattern and spread of invasion can predict late cervical lymph node metastasis in early tongue squamous cell carcinoma.

To determine the predictive indexes of late cervical lymph node metastasis in early tongue squamous cell carcinoma (TSCC). We retrospectively analyzed the cases of 25 patients with stage I/II TSCC who had undergone surgical treatment without elective neck dissection. We evaluated the relationships between clinicopathologic factors and the occurrence of late cervical lymph node metastasis.

Long-term survival by surgery and adjuvant chemotherapy in a patient with perforated extranodal NK/T-cell lymphoma of the small intestine: a retrospective case study.

Background: Extranodal natural killer/T-cell lymphoma, nasal type (ENKL) of the small intestine, is a disease with extremely poor prognosis. We describe treatment in a case which is novel in that it demonstrated long-term survival.

Case Presentation: A 68-year-old man was admitted to the emergency department of our hospital with the complaint of severe umbilical pain with tenderness and muscular defense.

Soil dust and bioaerosols as potential sources for resuspended Cs occurring near the Fukushima Dai-ichi nuclear power plant.

One of the current pathways to radiation exposure, caused by the radionuclides discharged during the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, is the inhalation of resuspended Cs present in the air. Although wind-induced soil particle resuspension is recognized as a primary resuspension mechanism, studies regarding the aftermath of the FDNPP accident have suggested that bioaerosols can also be a potential source of atmospheric Cs in rural areas, although the quantitative impact on the atmospheric Cs concentration is still largely unknown. We propose a model for simulating the Cs resuspension as soil particles and bioaerosols in the form of fungal spores, which are regarded as a potential candidate for the source of Cs-bearing bioaerosol emission into the air.

Comparative study of clinicians' and family members' perceptions of patients' end-of-life experiences.

Objective: End-of-life experiences (ELEs), such as deathbed visions (DBVs), have been reported worldwide. However, ELEs have rarely been discussed in clinical practice, possibly because of the different perceptions of ELEs among clinicians and families. Therefore, this study aimed to investigate the differences in perception regarding ELEs, especially DBVs, between clinicians and families.
