a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...

Sinonasal polyposis is considered to be the end-result of a chronic inflammatory process in the sinonasal mucosa. Its underlying mechanisms are still unclear, but the involvement of fungi has been suggested for many years. In the present study, we retrospectively evaluated the clinical and mycological profile of 161 patients with chronic rhinosinusitis (CRS) and nasal polyps who were undergoing...

BACKGROUND Patients with chronic rhinosinusitis with/without nasal polyps (CRSwNP/CRSsNP) benefit from endoscopic sinus surgery (ESS), with an estimated success rate of 80%. At present, the influence on clinical outcome after ESS of eosinophils, eosinophilic mucin (EM), and fungal hyphae (FH) in secretions remains unclear. By delineating CRS groups and subgroups based on the finding of eosinoph...

UNLABELLED Eosinophilic nasosinusal polyposis is a chronic inflammatory infection with elevated infiltration of eosinophils, which presents high rate of recurrence after surgical treatment. The continuous inflammatory process that leads to the formation of polyps requires constant clinical treatment. Contributing to the maintenance of eosinophilia are cytokines IL5 (interleukin-5) and GM-CSF (g...

OBJECTIVES/HYPOTHESIS Japanese patients with chronic rhinosinusitis with nasal polyps (CRSwNP), differing from European and U.S. patients, are suggested to show two distinct phenotypes: Th2-polarized and Th1-shifted immunity. The purpose of this study was to conduct clinical subgrouping of CRSwNP based on inflammatory cell infiltration, which was evaluated and supported by clinical backgrounds ...

UNLABELLED The research involving tissue factors, such as granulocyte macrophage colonies stimulating factor (GM-CSF) and interleukin 5 (IL-5), leads to the mechanisms involved in the maintenance of eosinophilia, which is essential for the pathogenesis on eosinophilic nasal polyps. Mitomycin C has been successfully used in otolaryngology. AIM The objective of this study was to evaluate the ef...

BACKGROUND Degranulation of eosinophils in target tissues is considered a key pathogenic event in major chronic eosinophilic diseases. However, because of a lack of appropriate methods, little is known about degranulation of eosinophils in common eosinophilic diseases. METHODS Using transmission electron microscopic (TEM) analysis, a novel approach has been devised and validated to quantify e...

OBJECTIVES/HYPOTHESIS Although many proinflammatory cytokines have been identified in nasal polyp tissue, the initial trigger that causes this inflammation characterized by edema, lymphocytosis, and eosinophilia, is still unknown. The purpose of the present study is to identify the presence of genetic polymorphisms in proinflammatory, anti-inflammatory, and chemokine genes that might contribute...

BACKGROUND Although drug-induced peripheral eosinophilia complicates antimicrobial therapy, little is known about its frequency and implications. OBJECTIVE We aimed to determine the frequency and predictors of antibiotic-induced eosinophilia and subsequent hypersensitivity reactions (HSRs). METHODS We evaluated a prospective cohort of former inpatients receiving intravenous antibiotic thera...
