The epithelial ovarian carcinomas, which make up more than 85% of human ovarian cancer, arise in the ovarian surface epithelium (OSE). The etiology and early events in the progression of these carcinomas are among the least understood of all major human malignancies because there are no appropriate animal models, and because methods to culture OSE have(More)
BACKGROUND This study aimed to examine public knowledge, attitudes and behaviors regarding antibiotic use in the community of Hong Kong. METHODS A cross-sectional phone survey was conducted in 2006 on people aged 18 or older who were uninstitutionalized Hong Kong residents regarding antibiotic use for upper respiratory tract infections (URTIs). RESULTS(More)
Epithelial ovarian carcinomas are the most common cause of death from gynecological malignancies and appear to arise from ovarian surface epithelium (OSE), but the exact mechanism of ovarian tumorigenesis has not been elucidated. Recent cloning of a second form of gonadotropin-releasing hormone (GnRH-II) has been reported in various human tissues including(More)
Fluoroscopically guided balloon dilation in treatment of complete obstruction of the nasolacrimal system was assessed in 39 eyes of 35 patients. All patients had severe epiphora. With nasal endoscopic guidance, a 0.018-inch guide wire was introduced through the superior punctum into the inferior meatus of the nasal cavity and was pulled out through the(More)
BACKGROUND Body mass index (BMI) and waist circumference (WC) correlate with cardiovascular (CV) risk factors in childhood which track into adulthood. WC provides a measure of central obesity, which has been specifically associated with CV risk factors. Reference standards for WC, and for WC and BMI risk threshold values are not established in Chinese(More)
Most epithelial ovarian tumors appear to arise from the ovarian surface epithelium (OSE). Even though it has been suggested that estrogen may be associated with ovarian tumorigenesis, the exact role of estrogen in the regulation of apoptosis in neoplastic OSE cells remains uncertain. Immortalized OSE (IOSE) cell lines were generated from human normal OSE.(More)
Epithelial ovarian cancer, which accounts for 80-90% of all ovarian cancers, is the most common cause of death from gynecological malignancies and is believed to originate from the ovarian surface epithelium. In the present study we investigated the expression of GnRH and its receptor in human ovarian surface epithelial (hOSE) cells and provided novel(More)
BACKGROUND Papillary thyroid carcinoma (PTC) frequently metastasizes to regional lymph nodes. Metastasis to the posterior neck, level V, is uncommon, and level V lymphadenectomy may lead to spinal accessory nerve injury and associated postoperative morbidities. The aim of this study was to assess the diagnostic efficiency of preoperative ultrasonography and(More)
The safety and long-term effectiveness of fluoroscopically guided balloon dilation for corrosive esophageal stricture was evaluated in 22 patients with a follow-up period of more than 1 year (range, 13-52 months). The average interval between corrosive agent ingestion and initial balloon dilation was 18 years (range, 2 months to 51 years). Balloons with a(More)
BACKGROUND The importance of quality-of-life (QoL) research has been recognised over the past two decades in patients with head and neck (H&N) cancer. The aims of this systematic review are to evaluate the QoL status of H&N cancer survivors one year after treatment and to identify the determinants affecting their QoL.
