Most acinic cell carcinomas arise within the parotid gland: extraparotid origin is rare. We encountered three cases of extraparotid acinic cell carcinoma arising in the buccal or palatal region, or the submandibular gland. All three tumors presented as a painless, slow-growing mass. CT imaging indicated that they were well defined, homogeneously enhanced, round masses. In one case, sonography demonstrated relatively homogeneous low echogenicity.

Rhinorrhea in allergic rhinitis (AR) is characterized by the secretion of electrolytes in the nasal discharge. The secretion of Cl– and HCO3 – is mainly regulated by cystic fibrosis transmembrane conductance regulator (CFTR) or via the calciumactivated Cl– channel anoctamin-1 (ANO1) in nasal gland serous cells. Interleukin-4 (IL-4), which is crucial in the development of allergic inflammation, increases the expression and activity of ANO1 by stimulating histamine receptors. In this study, we investigated ANO1 as a potential therapeutic target for rhinorrhea in AR using an ANO1 inhibitor derived from a natural herb. Ethanolic extracts (30%) of Spirodela polyrhiza (SPEtOH) and its five major flavonoids constituents were prepared. To elucidate whether the activity of human ANO1 (hANO1) was modulated by SPEtOH and its chemical constituents, a patch clamp experiment was performed in hANO1-HEK293T cells. Luteolin, one of the major chemical constituents in SPEtOH, significantly inhibited hANO1 activity in hANO1-HEK293T cells. Further, SPEtOH and luteolin specifically inhibited the calcium-activated chloride current, but not CFTR current in human airway epithelial Calu-3 cells. Calu-3 cells were cultured to confluency on transwell inserts in the presence of IL-4 to measure the electrolyte transport by Ussing chamber. Luteolin also significantly inhibited the ATP-induced increase in electrolyte transport, which was increased in IL-4 sensitized Calu-3 cells. Our findings indicate that SPEtOH and luteolin may be suitable candidates for the prevention and treatment of allergic rhinitis. SPEtOH- and luteolin-mediated ANO1 regulation provides a basis for the development of novel approaches for the treatment of allergic rhinitis-induced rhinorrhea.

OBJECTIVES: After Women's Health Initiative (WHI) study had been published, the use of hormone therapy (HT) have been decreasing even though it is the most effective therapy for menopausal symptom. The survey was conducted to investigate Korean menopausal women's perception of HT and behavior when they are treated by HT. METHODS: During 4 weeks from September 2009 to October 2009, total 600 women aged 45~64 participated in the survey by face to face interview. Out of answering women, women who have visited clinic/hospital at least 1 time to treat their menopausal symptom during last 1 year were included. One hundred fifty women for each age group, 45~49, 50~54, 55~59 and 60~64, were recruited in consecutive order. RESULTS: Eighty percent women who have visited clinic/hospital to treat menopausal symptom, visited obstetrics and gynecology. Only 16% of these women were current user, and other 84% of these women had no experience of HT (53%) or stopped therapy (31%). Among current user, only 9% of women have used HT more than 5 years. Eighty percent of current user had used HT less than 2 years. Most distressing menopausal symptom is 'hot flush' regardless HT experience. When doctor recommend HT, 72% of patients accept HT in overall. Among women who had no experience of HT, the most common reason of not to take HT was concern of side effects (51%). And 67% of women who had concern of side effects worried about cancer incidence. CONCLUSION: Many women with menopausal symptom do not take HT even though it is the most effective therapy. Most of women who take HT stop treatment within 1 year. Most common reason of not to take HT is concern about side effect, increasing incidence of cancer related to HT. Therefore, HT should be considered to short-term relief of menopausal symptoms and at the minimal dose, if possible.

The clear cell adenocarcinoma of uterine cervix is very rare tumor, and only 4-9% of entire adenocarcinoma appears to be diagnosed as clear cell adenocarcinoma. Its risk factor and pathogenesis are not exactly known, but intrauterine exposure to DES (diethyl stilbestrol) and associated non-steroidal estrogen during pregnancy before 18weeks is one known risk factor, and also hormonal change or genetic cause are suggested as the risk factors. The peak age of its occurrence has bimodal pattern, which are groups before 24 years-old and after 45 years-old, and clear cell adenocarcinoma arising in latter group is not associated with intrauterine DES exposure. It is also reported that 25% of young women who has clear cell adenocarcinoma had no history of hormonal exposure. The treatment and prognosis is similar to other kinds of uterine cervical adenocarcinoma. With a short literature review, we are reporting a case of 6-year-old girl who visited our clinic because of vaginal mass naturally fallen off with a minor bleeding which was finally diagnosed as clear cell adenocarcinoma, and had no maternal history of DES exposure during pregnancy.

Endometriosis is a relatively common gynecologic disease affecting women during their reproductive years. For its diagnosis, magnetic resonance imaging has been shown to have greater specificity than other modalities. Although lesions may show variable signal intensity due to numerous stages of bleeding, the characteristic finding of endometrioma which distinguishes it from other ovarian cystic masses is relatively high signal intensity on T1-weighted images and heterogeneous signal intensity with prominent shading on T2-weighted images. We report an atypical case involving a huge endometrioma. Because of varying signal intensity on T1- and T2-weighted images and scanty shading on T2-weighted images, the findings were misinterpreted and mucinous cystadenoma was diagnosed.
