Abstract
99 Background: Approximately 5,000 patients undergo breast reconstruction annually in the United Kingdom (2:1 ratio of immediate versus delayed respectively). Preservation of the breast envelope, i.e., skin and nipple areola complex (NAC) improves cosmesis. While skin-sparing mastectomy is an accepted modality for local control in appropriately selected patients, nipple-sparing mastectomy (NSM) remains controversial. In over 1,800 published NSM cases, the local event rate attributable to NAC preservation following NSM (therapeutic and prophylactic) is 0.16% with no evidence of deleterious impact on disease-free survival. In our cohort, patient selection criteria included: preoperative lesion characterisation; 5-mm margin acceptance; submission of separate nipple core specimens for paraffin block histological assessment and re-excision of all involved margins. This study is intended to evaluate the efficacy of loco-regional control in a consecutive cohort of patients, under uniform conditions undergoing nipple-sparing mastectomy and immediate breast reconstruction. We highlight the surgical technique used and propose in/exclusion criteria for appropriate patient selection. Methods: 84 consecutive patients underwent NSM and IBR at Frimley Park Hospital, Surrey, UK (IJL, RD) between January 2004 and December 2008. Data was accrued retrospectively from the institution’s clinical coding, electronic records, and WinPath database. Endpoints recorded include: the incidence of (occult) malignancy at the nipple margins; NAC subcutaneous tissue loss; local (NAC) recurrence rates and disease free survival. Results: The mean age was 51.1 years and follow-up 4.9 years. There was one case of local recurrence in a patient who declined re-excision of close/involved margins. The immediate peri-operative complication rate was within the national mastectomy breast reconstruction audit outcome guidelines. Conclusions: In appropriately selected patients, our findings support nipple preservation at the time of mastectomy and immediate reconstruction as this enhances the cosmetic outcome without compromising oncologic safety.

Abstract
Abstract
Background: As there is paucity of data on population-based screening for breast cancer using mammography and ultrasound for oriental young women aged 40-49 years, the peak of incidence rate and high proportion of dense breast, we aimed to evaluate the relative performance of detecting breast cancer between ultrasound and mammography and also to assess complementary efficacy of ultrasound to mammography screening.Methods: A total of 79,691 female residents aged 40-49 years were invited from community in Taiwan since late 2003. These participants were first randomly assigned to mammography (n=20040), ultrasound (n=20088), and control group (n=39563). The two former groups were further done by a cross-over design with mammography and ultrasound on alternate year until 2008. Detection rate and annual incidence rate of interval cancer as a percentage of the control group (I/E ratio) were compared between mammography and ultrasound.Results: The attendance rate of the first round was 59% (11921/20040) for mammography and 56% (11249/20088) for ultrasound. The repeated attendance rate of both groups was 85% in the second round and 91% in the third round. In the first round of screen, the detection rate of breast cancer for the mammography group (0.34%) was 1.5-fold compared with the ultrasound group (0.22%). The additional detection rate was 0.16% contributed from a subsequent ultrasound screen and 0.36% contributed from a subsequent mammogram screen. The combination of mammography with ultrasound was as three to four times as likely to detect breast cancer compared with the control group (annual incidence rate was 0.17%). The I/E ratio was lower after mammography screening than that after ultrasound screening.Conclusion: The current randomized controlled trial not only demonstrated higher detection rate and better performance using mammography but also indicated the complementary role of ultrasound applied to young Taiwanese women. This further suggests the optimal screening modality for young women in Asian country is to combine mammography with ultrasound.

Abstract
We evaluated the safety, reactogenicity and immunogenicity of escalating doses of a new Francisella tularensis Live Vaccine Strain (LVS) lot by scarification (SCAR) or subcutaneously (SQ) in humans. Subjects (N=10/group) received one dose of LVS via SCAR at 10(5),10(7) or 10(9)cfu/ml or SQ at 10(2), 10(3),10(4) or 10(5)cfu/ml; 14 subjects received placebo. All doses/routes were well tolerated. When compared to placebo, vaccination with 10(7) SCAR and 10(9) SCAR resulted in significantly higher serologic response frequencies, as measured by ELISA for IgG, IgM, IgA and microagglutination; whereas vaccination with 10(5) SCAR, 10(7) SCAR 10(9) SCAR and 10(5) SQ elicited a significantly higher interferon-gamma response frequency.

Abstract
OBJECTIVES To evaluate the rate of completion of anatomic surveys of fetuses in overweight and obese gravid patients as compared with normal controls. METHODS This was a retrospective review of anatomic ultrasound scans performed between 2004 and 2007. Women were stratified by prepregnancy body mass index (BMI) into normal weight (BMI, 18.5-24.9 kg/m(2)), overweight (BMI, 25.0-29.9 kg/m(2)) and obese Class I (BMI, 30.0-34.9 kg/m(2)), Class II (BMI, 35.0-39.9 kg/m(2)) and Class III (BMI >or= 40.0 kg/m(2)) groups. Rates of completion of basic and comprehensive scans, gestational age at completion and number of scans required were compared. RESULTS For the 7140 patients included, completion rates for both the basic (normal weight, n = 2253 (79%); overweight, n = 1771 (76%); obese Class I, n = 767 (72%), Class II, n = 323 (61%) and Class III, n = 171 (49%)) and comprehensive (normal weight, n = 1234 (43%); overweight, n = 930 (40%); obese Class I, n = 404 (38%), Class II, n = 215 (41%) and Class III, n = 108 (31%)) surveys decreased significantly with increasing BMI (P < 0.00001). For surveys completed, the mean number of scans required was significantly higher for obese patients (basic: normal weight 1.3 vs. obese Class III 1.9; comprehensive: normal weight 1.7 vs. obese Class III, 2.2)(P < 0.00001). The overall completion rate improved at each gestational week, but was best between 20 and 23 weeks for obese patients. CONCLUSIONS As maternal BMI increases, the rate of completion of anatomic surveys decreases and the number of scans required increases. Delaying the initial survey until 20 weeks' gestation may improve the capacity to complete the examination in a single visit. It should be noted that these results represent completion rates at a tertiary referral center, and therefore may not reflect community experience.

Abstract
Pediatric renal transplant recipients were enrolled in a multicenter, randomized, double-blind trial of steroid withdrawal. Subjects received basiliximab, calcineurin inhibitor, sirolimus and steroids. Of 274 subjects enrolled, 19 (6.9%) subjects developed posttransplant lymphoproliferative disorder (PTLD). The relative hazard (RH) for PTLD was 5.3-fold higher in children aged < or =5 versus those >12 years (p = 0.0017). EBV seronegative subjects had a 4.7-fold higher RH compared to EBV positive subjects (p = 0.02). Among EBV donor+/recipient- (D+/R-) subjects, the RH increased by 6.1-fold (p = 0.0001). In a multivariate model, risk factors included recipient age < or =5 years (RH 3.2, 95% CI: 1.1-9.6, p = 0.034) and EBV D+/R- status (RH 7.7, 95% CI: 1.6-35.9, p = 0.010). Of 19 patients with PTLD, 17 are alive with functioning grafts and 2 lost their grafts, 1 of whom subsequently died of recurrent PTLD. This 'robust' immunosuppression protocol was associated with low rejection rates but an unacceptably high incidence of PTLD. The combination of basiliximab, calcineurin inhibitor, sirolimus and steroids resulted in over-immunosuppression in a high-risk pediatric population and we do not recommend its use. Future studies must include routine viral monitoring to permit early identification of viral activity and a protocol driven reduction of immunosuppression aimed at avoiding complications.

Abstract
OBJECTIVES Dose-dependant gastrointestinal and cardiovascular side-effects limit the use of NSAIDs in the management of RA. The n-3 essential fatty acids (EFAs) have previously demonstrated some anti-inflammatory and NSAID-sparing properties. The objective of this study was to determine whether cod liver oil supplementation helps reduce daily NSAID requirement of patients with RA. METHODS Dual-centre, double-blind placebo-controlled randomized study of 9 months' duration. Ninety-seven patients with RA were randomized to take either 10 g of cod liver oil containing 2.2 g of n-3 EFAs or air-filled identical placebo capsules. Documentation of NSAID daily requirement, clinical and laboratory parameters of RA disease activity and safety checks were done at 0, 4, 12, 24 and 36 weeks. At 12 weeks, patients were instructed to gradually reduce, and if possible, stop their NSAID intake. Relative reduction of daily NSAID requirement by >30% after 9 months was the primary outcome measure. RESULTS Fifty-eight patients (60%) completed the study. Out of 49 patients 19 (39%) in the cod liver oil group and out of 48 patients 5 (10%) in the placebo group were able to reduce their daily NSAID requirement by >30% (P = 0.002, chi-squared test). No differences between the groups were observed in the clinical parameters of RA disease activity or in the side-effects observed. CONCLUSIONS This study suggests that cod liver oil supplements containing n-3 fatty acids can be used as NSAID-sparing agents in RA patients.

Abstract
Statistical analysis of stormwater runoff data enables general identification of runoff characteristics. Six catchments with different urban surface type including roofs, roadway, park, and residential/commercial in Macau were selected for sampling and study during the period from June 2005 to September 2006. Based on univariate statistical analysis of data sampled, major pollutants discharged from different urban surface type were identified. As for iron roof runoff, Zn is the most significant pollutant. The major pollutants from urban roadway runoff are TSS and COD. Stormwater runoff from commercial/residential and Park catchments show high level of COD, TN, and TP concentration. Principal component analysis was further done for identification of linkages between stormwater quality and urban surface types. Two potential pollution sources were identified for study catchments with different urban surface types. The first one is referred as nutrients losses, soil losses and organic pollutants discharges, the second is related to heavy metals losses. PCA was proved to be a viable tool to explain the type of pollution sources and its mechanism for different urban surface type catchments.

Abstract
BACKGROUND Improving health literacy can be a strategy for the achievement of public health goals, and the concept of the Health Promoting School can help to build on the health literacy of students. The Centre for Health Education and Health Promotion of The Chinese University of Hong Kong launched the Hong Kong Healthy Schools Award (HKHSA) in 2001. This paper reports the results for the ten secondary schools that underwent assessment in 2002. METHODS Based on the overall score for each school, cluster analysis was performed. Each cluster of schools reflected different levels of HKHSA achievement. RESULTS This study has shown that those schools reaching high Health Promoting School standards have adopted the concept of a whole school approach in addressing health and social issues, rather than topic-based and school-located health promotion. The schools performing less satisfactorily mainly follow a prescriptive approach. CONCLUSIONS These results are a good source of reference for other schools in their Health Promoting Schools programmes.

Abstract
We analyzed autopsies performed in a Canadian blood and marrow transplantation (BMT) program. We aimed to assess variables that predict the performance of an autopsy, whether rates of autopsy are changing, and the rate of discordance between clinical and autopsy diagnoses. All deceased adult patients from January 1990 to December 2004 were reviewed. Autopsy rates were compared to a large teaching hospital. Of 476 myeloablative BMT patients, 225 died and 48 (27%) underwent autopsy. Autopsy was more likely in patients dying: <100 days post-BMT, in the intensive care unit, after allografting, and on weekends. Autopsy rates among BMT patients declined during the three time periods (1990-1994, 1995-1999, 2000-2004). The autopsy rate at the teaching hospital showed a similar downward temporal trend. Major and minor disagreements at autopsy were present in 16 (34%) and 14 (30%) of cases, respectively. There was no change in discordance rates over time. Thus, despite advances in diagnostic procedures, high levels of disagreement between clinical and autopsy diagnoses for BMT patients persist as autopsy rates decline. We recommend that the autopsy regains its role as a valuable investigation. This may become especially relevant in an era where patients with medical comorbidities are undergoing reduced-intensity BMT.

Abstract
OBJECTIVE To describe a newly modified laparoscopic presacral neurectomy procedure and to evaluate the long-term benefits of the surgery as a treatment for midline dysmenorrhea. METHOD Eighty-eight reproductive female patients with midline dysmenorrhea were enrolled in the non-randomized prospective study. There were fifty-five patients in the modified laparoscopic presacral neurectomy (MLPSN) group and thirty-three patients in the conventional laparoscopic presacral neurectomy (LPSN) group. All patients received post-surgery follow-up of more than eight years for evaluation with respect to pain relief, recurrence, and complications. RESULTS Upon receipt of surgery, the MLPSN and the LPSN groups both demonstrated a significant decrease (P<0.001) in the mean pain score when compared to the pre-surgery mean pain scores. However, the probability of recurrence during the eight years of follow-up was 81.8% (27 patients) in the LPSN group, compared to 43.6% (24 patients) in the MLPSN group, resulting in a significantly lower long-term recurrence rate in the MLPSN group, compared to the LPSN group (P<0.05). No patients in the MLPSN group had long-term complications and one patient had constipation after surgery in the LPSN group. CONCLUSION The modified laparoscopic presacral neurectomy procedure provides an alternative for those patients who suffer intractable midline dysmenorrhea. This surgery is relatively simple and safe and could result in a satisfactory long-term outcome in the intervention of midline dysmenorrhea.

Abstract
BACKGROUND Human rights legislation safeguards the privacy and dignity of patients. OBJECTIVE To assess the effectiveness in terms of patient assessed privacy of confidential registration. DESIGN Randomised controlled trial. SETTING Emergency Department, University Hospital of Wales. PARTICIPANTS A total of 302 patients aged over 15 years. MAIN OUTCOME MEASURES Binary choices and ordinal visual analogue scores from a validated questionnaire on self reported measures: patient ability and preference to speak to receptionists and disclose confidential information without being overhead and concern about disclosure of items of confidential personal information. RESULTS Patients who registered in a screened area felt significantly more able to tell receptionists things they did not want others to hear. Control patients were significantly more concerned than intervention patients that others heard their name, address, date of birth, reason for emergency department attendance, and telephone number, but not their marital status. Overall, intervention patients were less concerned about disclosure of information and that they had been overheard. CONCLUSIONS Patients value privacy when they register and are concerned if others can hear them tell receptionists who they are, how to contact them, and why they are there. Confidential registration should be instituted in health services. Confidential registration increased patient privacy and should be instituted in health services.

Abstract
OBJECTIVES To assess the efficacy of a cannabis-based medicine (CBM) in the treatment of pain due to rheumatoid arthritis (RA). METHODS We compared a CBM (Sativex) with placebo in a randomized, double-blind, parallel group study in 58 patients over 5 weeks of treatment. The CBM was administered by oromucosal spray in the evening and assessments were made the following morning. Efficacy outcomes assessed were pain on movement, pain at rest, morning stiffness and sleep quality measured by a numerical rating scale, the Short-Form McGill Pain Questionnaire (SF-MPQ) and the DAS28 measure of disease activity. RESULTS Seventy-five patients were screened and 58 met the eligibility criteria. Thirty-one were randomized to the CBM and 27 to placebo. Mean (S.D.) daily dose achieved in the final treatment week was 5.4 (0.84) actuations for the CBM and 5.3 (1.18) for placebo. In comparison with placebo, the CBM produced statistically significant improvements in pain on movement, pain at rest, quality of sleep, DAS28 and the SF-MPQ pain at present component. There was no effect on morning stiffness but baseline scores were low. The large majority of adverse effects were mild or moderate, and there were no adverse effect-related withdrawals or serious adverse effects in the active treatment group. CONCLUSIONS In the first ever controlled trial of a CBM in RA, a significant analgesic effect was observed and disease activity was significantly suppressed following Sativex treatment. Whilst the differences are small and variable across the population, they represent benefits of clinical relevance and show the need for more detailed investigation in this indication.

Abstract
The occurrence of SARS in March 2003 has resulted in an increased interest, worldwide in emerging infectious diseases. The SARS experience provided us a lesson on the importance of promoting hygienic practices among individuals and different working sectors. In Hong Kong, a voluntary organization called the UNITE proposed a Hygiene Charter which aimed at taking hygiene to new levels. This action has been supported by individuals and different sectors including the Personal and Family, Management, Buildings, Catering, Education, Finance and Commercial, Industrial, Medical and Health, Public Transportation, Social Welfare, Sports and Culture and Tourism. As promotion and maintenance of environmental health requires input from different sectors, the signing of the Hygiene Charter provides an opportunity for individuals and the public to show their pledge and commitment to good hygiene practices. As a result, with environment improvement and good infectious disease control measures, prevention of epidemics of infectious diseases is deemed to be possible.

Abstract
A needs assessment is recommended to be carried out before planning resource allocation in a community as it could help to identify the needs of the people. This study illustrated the importance of needs assessment in planning health promoting school initiatives by comparing the results of youth risk behaviours surveys conducted at two districts of Hong Kong, namely Tsuen Wan and North District. The findings indicated that the two districts should prioritize their resources in respect to their urgent needs. A higher proportion of students from Tsuen Wan participated in vigorous exercise regularly in comparison to students from North District. Students from North District consumed more vegetable per week and exhibited less depressive symptoms than students from Tsuen Wan. The availability of data on youth risk behaviours of the two districts would provide information for strategic planning and direct decision-making in youth health programmes.

Abstract
Formalin-fixed paraffin embedded (FFPE) tumor tissue provides an opportunity to perform retrospective genomic studies of tumors in which chromosomal imbalances are strongly associated with oncogenesis. The application of comparative genomic hybridization (CGH) has led to the rapid accumulation of cytogenetic information on osteosarcoma (OS); however, the limited resolving power of metaphase CGH does not permit precise mapping of imbalances. Array CGH allows quantitative detection and more precise delineation of copy number aberrations in tumors. Unfortunately the high cost and lower density of BACs on available commercial arrays has limited the ability to comprehensively profile copy number changes in tumors such as OS that are recurrently subject to genomic imbalance. In this study a cDNA/EST microarray including 18,980 human cDNAs (which represent all 22 pairs of autosomal chromosomes and chromosome X) was used for CGH analysis of eight OS FFPE. Chromosomes 1, 12, 17, and X harbored the most imbalances. Gain/amplification of X was observed in 4/8 OS, and in keeping with other recent genomic analyses of OS, gain/amplification of 17p11.2 was often accompanied by a distal deletion in the region of the p53 gene. Gain/amplification of the X chromosome was verified using interphase FISH carried out on a subset of OS FFPE sections and OS tissue arrays.

Abstract
The severe acute respiratory syndrome (SARS) is a rapidly progressive, and sometime fatal disease with more than 1800 patients in over a dozen countries in Asia, Europe, and North America (including the United States and Canada) within two months. On 12 March 2003, the World Health Organisation (WHO) issued a global alert about SARS so it became a global challenge. Strengthening the public health measures at schools would protect children as well as providing the students an opportunity to learn about infectious disease control through life event approach. The public health measures at schools include two important components: basic understanding of the disease so schools would put on high alert on caution cases, and the measures to improve environmental hygiene at schools and preventive measures to stop infectious disease transmission. This will help to empower the whole community the readiness to deal with other outbreaks in the future.
