Dynamic chest radiographic evaluation of the effects of tiotropium/olodaterol combination therapy in chronic obstructive pulmonary disease: the EMBODY study protocol for an open-label, prospective, single-centre, non-controlled, comparative study.

Introduction: To date, there is limited evidence on the effects of bronchodilators on respiratory dynamics in chronic obstructive pulmonary disease (COPD). Dynamic chest radiography (DCR) is a novel radiographic modality that provides real-time, objective and quantifiable kinetic data, including changes in the lung area (Rs), tracheal diameter, diaphragmatic kinetics and pulmonary ventilation during respiration, at a lower radiation dose than that used by fluoroscopic or CT imaging. However, the therapeutic effect of dual bronchodilators on respiratory kinetics, such as chest wall dynamics and respiratory muscle function, has not yet been prospectively evaluated using DCR.

Two cases of idiopathic pulmonary fibrosis evaluated by dynamic digital radiography for diaphragmatic motion and disease progression.

Forced vital capacity has been utilized as a parameter of disease progression in idiopathic pulmonary fibrosis (IPF); however, its measurement is difficult when patients do not understand or cooperate. Dynamic digital radiography (DDR) enables sequential chest X-ray imaging during breathing, with lower radiation doses compared to conventional fluoroscopy or computed tomography. There is accumulating evidence showing that parameters obtained from DDR, particularly those related to diaphragmatic dynamics, are correlated with pulmonary function parameters, and are useful for pathophysiological evaluation.

Transanal total mesorectal excision in the prone jackknife position without being conscious of the size of prostatic enlargement for lower rectal cancer.

In 1982, it was demonstrated that a total mesorectal excision alone could achieve low rectal cancer recurrence rates in the pelvis and high disease-free survival rates. Nowadays, the total mesorectal excision is the gold-standard surgery for rectal cancer. Currently, the transanal total mesorectal excision has attracted attention as a promising alternative to the anterior approach.

Intravoxel incoherent motion imaging has the possibility to detect liver abnormalities in young Fontan patients with good hemodynamics.

Introduction: Liver fibrosis and cirrhosis are one of the critical complications in Fontan patients. However, there are no well-established non-invasive and quantitative techniques for evaluating liver abnormalities in Fontan patients. Intravoxel incoherent motion diffusion-weighted imaging with MRI is a non-invasive and quantitative method to evaluate capillary network perfusion and molecular diffusion.

[Gastric Neuroendocrine Carcinoma(NEC)Treated with CDDP plus CPT-11 Chemotherapy].

A 69-year-old man with chronic gastritis, reflux esophagitis, esophageal hiatal hernia, and history of appendicitis surgery complained of difficulty swallowing. Upper gastrointestinal endoscopy revealed a 10 cm sized Type 3 gastric cancer. Immunostaining was positive for chromogranin A(2+), synaptophysin(3+), CD56(-), and Ki-67>70%.
