Unlabelled: The purpose of this study is to (1) to determine if treatment of underlying allergic rhinitis (AR) in children will affect epistaxis outcome, (2) to compare efficacy of three outpatient AR treatment regimens in epistaxis outcomes, and (3) to investigate potential factors in the pathogenesis of epistaxis with underlying AR. A single-blind randomized-controlled study was conducted in the Otolaryngology clinic in KK Women's and Children's Hospital. Sixty children aged below 18 years with underlying untreated AR, with first presentation of epistaxis, were randomized to three different AR treatments: treatment 1, antihistamine (20 patients); treatment 2, nasal steroid spray (20 patients); and treatment 3, both antihistamine and nasal steroid spray (20 patients).

Purpose: To assess whether the benefits of adding cisplatin (CDDP) concurrent with radiotherapy, followed by adjuvant CDDP and fluorouracil, justifies the toxicity cost for nasopharyngeal cancer (NPC) using the quality-adjusted time without symptoms or toxicity (Q-TWiST) approach.
Methods And Materials: One hundred seven patients treated with radiotherapy (RT) and 111 with concurrent chemotherapy and radiotherapy (CRT) were analyzed. The overall survival was divided into three health states: time on active treatment only, during which any subjective nonhematologic toxic event of grade > = 3 was reported; time without symptoms of disease relapse; or treatment and time following first disease RELapse.
Purpose: To investigate the relationship between body mass and health-related quality of life (HRQOL) among Singaporean adolescents. Variation in this relationship by age, gender and ethnicity, and association of HRQOL with change in body mass over time and with demographic, socioeconomic and health variables were also assessed.
Methods: HRQOL was assessed for Singaporean adolescents aged 11-18 from their own (N=1,249) and their parent’s (N=948) perspective using PedsQLTM 4.

Purpose: To establish the normal measurements of diameter and cross-sectional area of the Chinese extraocular muscles (EOMs) and optic nerve-sheath complex (ON) as seen on high-field (3-Tesla; 3T) magnetic resonance imaging (MRI).
Methods: Coronal 3T MRI of the orbit (TR, 700 ms; TE, 15 ms; FOV, 160 mm; matrix, 256 x 256; slice thickness, 1 mm; and slice gap, 0) was performed on 80 normal Chinese volunteers. T1-weighted images were analyzed with computer-assisted segmentation.
Background: Laparoscopic colectomy has yet to gain widespread acceptance in cost-conscious health-care institutions. The aim of the present study was to define the cost-benefit relationship of laparoscopic versus open colectomy.
Methods: Thirty-two consecutive patients undergoing elective laparoscopic colectomy (LC) by a single colorectal surgeon between August 2004 and September 2005 were reviewed.
Purpose: To determine the impact of visual impairment on health-related quality of life (QoL) measures in adolescents.
Design: School-based, cross-sectional study.
Methods: Adolescents aged 11 to 18 years from the Singapore Cohort Study of the Risk Factors for Myopia were analyzed.

Introduction: Our aim in this study was to investigate whether a linear relationship exists between soft- to hard-tissue changes for both maxillary and mandibular landmarks over a wide range of skeletal changes.
Methods: The sample consisted of 30 Chinese patients with Class III malocclusion treated with bilateral sagittal split osteotomy and LeFort I advancement. Lateral cephalograms were taken within 2 months before surgery and at least 6 months after surgery.
Aims: Patients with chronic kidney disease (CKD) have high cardiovascular risk. Although stress imaging provides accurate risk estimation in this population, it is unknown if combinatorial cardiac imaging adds incremental value.
Methods And Results: We performed transthoracic echocardiography and stress single photon emission computed tomography (SPECT) to assess their value in predicting late cardiovascular disease (CVD) mortality in 200 patients with creatinine clearance <60 mL/min without a history of coronary heart disease.
Purpose: The aims of this retrospective study were to assess the subjective accuracy of predictions generated by a computer imaging software in Chinese patients who had undergone orthognathic surgery and to determine the influence of initial dysgnathia and complexity of the surgical procedure on prediction accuracy.
Patients And Methods: The sample consisted of 40 Chinese patients who had completed treatment involving orthodontics and orthognathic surgery. All the patients had lateral cephalometric radiographs and profile photographs taken within 3 months before surgery and at least 6 months after surgery.
The fecal microbiota of 37 infants with (n = 20) or without (n = 17) probiotic administration was evaluated on D 3, and at 1, 3, and 12 mo by fluorescence in situ hybridization-flow cytometry (FISH-FC), PCR, and bacteriological culture methods. They represent consecutive subjects of an ongoing double-blind, placebo-controlled trial on a probiotic formula (LGG and Bifidobacterium longum) administered during the first 6 mo of life. Despite varying composition in each baby, there was a general bacterial colonization pattern in the first year.

We explore whether this can be extended more generally to allow for smaller trials to be conducted using a case study involving a trial of nasopharyngeal carcinoma. The external information available at various points during the trial is first summarised in the form of 'prior distributions'.

Background: Clinical studies have evaluated the safety and efficacy of adjunctive X-sizer (EndiCOR Inc, San Clemente, CA) in percutaneous coronary intervention (PCI). However, patient and lesion subsets were highly selected, and extrapolation of the results to daily practice is problematic.
Methods: X-sizer thrombectomy was performed in 200 procedures from August 2000 to July 2005.
Objective: In the thrombolytic era, it was reported that in the presence of significant coronary stenosis, lowering diastolic blood pressure (DBP) below a critical threshold would result in a paradoxical increase in the occurrence of myocardial infarction (MI). We sought to re-evaluate this J-shaped relation in the era of pharmacoinvasive therapy.
Methods: A total of 182 patients who underwent early (<1 week, mean 2.
