Abstract
OBJECTIVES Studies of public health reporting have only examined multiple episodes of the same communicable disease within an individual. We aimed to characterize Montreal residents with multiple reportable disease episodes from 1990 to 2012, while accounting for all types of reportable diseases. STUDY DESIGN Retrospective cohort study. METHODS We performed an exploratory analysis using descriptive statistics, contingency tables, and logistic regression. RESULTS There were 157,839 individuals with at least one disease report and a total of 179,455 disease reports. The 9.8% of subjects with more than one episode accounted for 20.7% of all reported episodes. Among subjects with four or fewer episodes, 54.0% were women, while 74.3% of subjects with five or more episodes were men. Subjects with multiple episodes were more likely to be reported for sexually transmitted infections than were persons with a single episode [difference of proportions: 10.4% (95% CI: 10.0%-10.9%)] and to reside in the neighbourhood encompassing Montreal's gay village. CONCLUSIONS Individuals with multiple communicable disease reports place a large burden on public health officials. These results may help guide investigation and prevention efforts to reduce the number of excess episodes.

Abstract
We identified an MSH6 mutation (c.10C>T, p.Gln4*) causing Lynch syndrome (LS) in 11 French Canadian (FC) families from the Canadian province of Quebec. We aimed to investigate the molecular and clinical implications of this mutation among FC carriers and to assess its putative founder origin. We studied 11 probands and 27 family members. Additionally 6433 newborns, 187 colorectal cancer (CRC) cases, 381 endometrial cancer (EC) cases and 179 additional controls, all of them from Quebec, were used. Found in approximately 1 of 400 newborns, the mutation is one of the most common LS mutations described. We have found that this mutation confers a greater risk for EC than for CRC, both in the 11 studied families and in the unselected cases: EC [odds ratio (OR) = 7.5, p < 0.0001] and CRC (OR = 2.2, p = 0.46). Haplotype analyses showed that the mutation arose in a common ancestor, probably around 430-656 years ago, coinciding with the arrival of the first French settlers. Application of the results of this study could significantly improve the molecular testing and clinical management of LS families in Quebec.

Abstract
OBJECTIVES Ageing leads to characteristic changes in the appearance of facial skin. Among these changes, we can distinguish the skin topographic cues (skin sagging and wrinkles), the dark spots and the dark circles around the eyes. Although skin changes are similar in Caucasian and Chinese faces, the age of occurrence and the severity of age-related features differ between the two populations. Little is known about how the ageing of skin influences the perception of female faces in Chinese women. The aim of this study is to evaluate the contribution of the different age-related skin features to the perception of age and attractiveness in Chinese women. METHODS Facial images of Caucasian women and Chinese women in their 60s were manipulated separately to reduce the following skin features: (i) skin sagging and wrinkles, (ii) dark spots and (iii) dark circles. Finally, all signs were reduced simultaneously (iv). Female Chinese participants were asked to estimate the age difference between the modified and original images and evaluate the attractiveness of modified and original faces. RESULTS Chinese women perceived the Chinese faces as younger after the manipulation of dark spots than after the reduction in wrinkles/sagging, whereas they perceived the Caucasian faces as the youngest after the manipulation of wrinkles/sagging. Interestingly, Chinese women evaluated faces with reduced dark spots as being the most attractive whatever the origin of the face. The manipulation of dark circles contributed to making Caucasian and Chinese faces being perceived younger and more attractive than the original faces, although the effect was less pronounced than for the two other types of manipulation. CONCLUSION This is the first study to have examined the influence of various age-related skin features on the facial age and attractiveness perception of Chinese women. The results highlight different contributions of dark spots, sagging/wrinkles and dark circles to their perception of Chinese and Caucasian faces.

Abstract
BACKGROUND Sleep lines are caused by individual's sleeping positions and should be differentiated from expression wrinkles. OBJECTIVE The aim of the study was to investigate possible risk factors for sleep lines on a sizeable sample of middle-aged Caucasian women. METHODS This study involved a sample of 542 French middle-aged women (44 to 70 years old) from Paris area. Three standardized facial photographs (face and profiles) were examined independently by two dermatologists allowing the identification of sleep lines and the evaluation of the severity of several facial skin features. Possible impacts of MC1R gene polymorphisms were tested using logistic regression models. RESULTS Sixty women (11%) had facial sleep lines and showed generally more than one sleep line. The sleep lines were often located on the forehead, along the nose, on the cheeks and under the eyes, and more rarely on the chin. As expected, the sleep lines were associated with age, and the women with sleep lines showed also more severe signs of skin ageing. After adjustment on possible confounders, the presence of two major diminished function variants of the MC1R gene was identified as a strong risk factor for sleep lines [adjusted odds ratios (AOR) (95% CI): 8.25 (2.62-25.97)]. DISCUSSION/CONCLUSION The data in the literature are scarce and this study is the first to be conducted on a sizeable sample of women. Our results suggest that genetic variations of MC1R are important determinants of the development of sleep lines.

Abstract
Women receiving neoadjuvant systemic therapy for primary operable or inoperable breast cancer can potentially benefit in a number of ways, but the main advantage, which has been consistently demonstrated, is improved tumour resectability. Given the improvement in outcomes with the adjuvant use of trastuzumab in patients with early-stage breast cancer positive for the human epidermal growth factor receptor 2 (her2), questions have been raised about the use of trastuzumab in the neoadjuvant setting. The present paper reviews the currently available data and outlines suggestions from a panel of Canadian oncologists about the use of trastuzumab and other her2-targeted agents in the neoadjuvant setting. The panel focussed on the use of trastuzumab and other her2-targeted agents as neoadjuvant therapy in primary operable, locally advanced, and inflammatory breast cancer; and possible choices of chemotherapeutic regimens with trastuzumab.
The suggestions described here will continue to evolve as data from current and future trials with trastuzumab and other her2-targeted agents emerge.

Abstract
BACKGROUND Atopic dermatitis (AD) is associated with null mutations in the filaggrin (FLG) gene. OBJECTIVE To assess the impact of FLG null mutations on biophysical properties and the molecular composition of the stratum corneum (SC) in healthy individuals and AD patients. METHODS A total of 196 French adults, including 97 with a history of mild to moderate AD, were genotyped for the three major European FLG mutations. Components of the natural moisturizing factor (NMF), lipids and water content in the SC were determined using Raman spectroscopy. In addition, trans-epidermal water loss, capacitance and pH of the SC were measured. RESULTS Stratum corneum concentrations of total NMF, water, ornithine and urocanic acid (UCA) were significantly lower in AD patients than in healthy controls. Null mutations of FLG were detected in 4% of controls and 10% of AD patients. FLG mutations were associated with increased SC levels of lactate, reduced concentrations of most other NMF components and higher disease severity in AD patients. In AD patients without FLG mutations, the content of NMF constituents decreased with increasing disease severity. The concomittant presence of low concentrations of histidine, alanine and either glycine or pyrrolidone-5-carboxylic acid (PCA) in the SC was associated with FLG mutations with 92% specificity. CONCLUSIONS Our findings suggest a low prevalence of FLG mutations in mild AD and support an important role for filaggrin in determining the physicochemical parameters of the SC. The combined measurement of several filaggrin breakdown products in the SC may be useful to specifically predict the presence of FLG mutations.

Abstract
Breast cancer positive for HER2 (human epidermal growth factor receptor 2) is associated with a poor prognosis for patients with both early-stage and metastatic breast cancer. Trastuzumab has been shown to be effective and is now considered the standard of care for early-stage patients with HER2-positive breast cancer. In that population, trastuzumab has been studied in six randomized clinical trials. Overall, use of this agent leads to a significant reduction in risk of disease recurrence and improvement in overall survival. Despite the strong evidence for the use of trastuzumab in managing HER2-positive early breast cancer (EBC), a number of clinical controversies remain. The authors of this paper undertook a review of the available scientific literature on adjuvant trastuzumab to produce practical considerations from Canadian oncologists. The panel focused their discussion on five key areas: Management of node-negative disease with tumours 1 cm or smaller in size. Management of HER2-positive EBC across the spectrum of the disease (that is, nodal and steroid hormone receptor status, tumour size) Timing of trastuzumab therapy with chemotherapy for early-stage disease: concurrent or sequential. Treatment duration of trastuzumab for EBC. The role of non-anthracycline trastuzumab-based regimens.

Abstract
BACKGROUND The objective of this study was to assess the association between melanocortin-1 receptor (MC1R) variants and the severity of facial skin photoaging. METHODS The study population comprised 530 French middle-aged women between 44 and 70 years. A trained dermatologist graded the severity of facial skin photoaging from photographs using Larnier's global scale. Logistic regressions were performed to assess the influence of MC1R polymorphism on severe photoaging (grades 1-3 vs. 4-6), with adjustment for possible confounders (demographic and phenotypic data, and sun exposure intensity). RESULTS Overall, 35% of the women were wild-type homozygotes, 49% had one variant, 15% had two variants, and 1% had at least one rare variant. After adjustment for possible confounders, the presence of two major diminished function variants was found to be a risk factor for photoaging (adjusted odds ratio=5.61; 95% confidence interval [1.43-21.96]). DISCUSSION Our results suggest that genetic variations of MC1R are important determinants for severe photoaging.

Abstract
545 Background: Patients (pts) with MCRC refractory/resistant to Irinotecan and Oxaliplatin have a poor prognosis. Sunitinib is an oral TKI that selectively inhibits the VEGFR 1, 2, 3, PDGFR and FLT3, CSF-1R, RET. Phase II studies with single agent sunitinib in patients with MCRC did not demonstrate a meaningful ORR but showed acceptable safety profile and warranted further study. Methods: We conducted a phase II escalating dose of sunitinib (S) and capecitabine (C) to assess the efficacy of this oral treatment given on a 2 wks every 3 wks schedule, (level 0, S: 37,5 mg, C: 2,000mg/m2, level +1, S: 50 mg, C: 2,000 mg/m2, level +2, S: 50 mg, C: 2,500 mg/m2 and level -1:S: 25 mg, C: 1,500 mg/m2. Treatment was initiated at level 0 and increased at level +1 and +2 at cycle 3 and 5 if no grade 2/3 toxicity was observed. Between 02.2009 and 06.2010, 15 pts previously exposed to oxaliplatin/irinotecan/bevazizumab were enrolled, all of them had progressive disease at the time of study entry. Primary objective was ORR. Treatment was given until PD or unacceptable toxicity. Results: Pts characteristics were: sex: 12M/3F, median age: 65 years [41-75], primary tumors: colon: 13, rectum: 2, ECOG PS 0/1: 8/7, median nb of metastatic sites: 3, KRAS status: WT/MT/Unknown: 1/9/5. Escalating to level +1:53%, level +2: 7%. Median nb of cycles received/pt: 5. All pts were evaluable for toxicity (tox): SAEs: 40%, any tox. grade 1/2/3(%): 93/60/ 40. Neutropenia gr. 1/2/3(%): 13/13/7, thrombocytopenia gr.1/2/3(%): 13/20/7. Fatigue gr.1/2/3(%): 27/20/7. Nausea gr.1: 27%. Diarrhea gr.1: 13%. Hand foot syndrome gr. 1/2/3 (%): 13/13/27. Mucositis gr. 1/2/3(%): 7/20/7. Hypertension gr.2: 13%. Thyroïd gr.1: 27%. ORR (CR+PR): 0%, confirmed SD: 7/15: 47%, PD: 8/15: 53%. Median PFS: 137 days [95%CI: 112-162], median OS: 291 days [95%CI: 99-482]. Conclusions: In this heavily pretreated patients, sunitinib in combination with capecitabine appears feasible, with acceptable toxicity. 47% of patients had a confirmed stable disease. Although no objective response was observed, the high level of stable disease may suggest a role of this combination for maintenance therapy. [Table: see text]

Abstract
BACKGROUND Developing and updating high-quality guidelines requires substantial time and resources. To reduce duplication of effort and enhance efficiency, we developed a process for guideline adaptation and assessed initial perceptions of its feasibility and usefulness. METHODS Based on preliminary developments and empirical studies, a series of meetings with guideline experts were organised to define a process for guideline adaptation (ADAPTE) and to develop a manual and a toolkit made available on a website (http://www.adapte.org). Potential users, guideline developers and implementers, were invited to register and to complete a questionnaire evaluating their perception about the proposed process. RESULTS The ADAPTE process consists of three phases (set-up, adaptation, finalisation), 9 modules and 24 steps. The adaptation phase involves identifying specific clinical questions, searching for, retrieving and assessing available guidelines, and preparing the draft adapted guideline. Among 330 registered individuals (46 countries), 144 completed the questionnaire. A majority found the ADAPTE process clear (78%), comprehensive (69%) and feasible (60%), and the manual useful (79%). However, 21% found the ADAPTE process complex. 44% feared that they will not find appropriate and high-quality source guidelines. DISCUSSION A comprehensive framework for guideline adaptation has been developed to meet the challenges of timely guideline development and implementation. The ADAPTE process generated important interest among guideline developers and implementers. The majority perceived the ADAPTE process to be feasible, useful and leading to improved methodological rigour and guideline quality. However, some de novo development might be needed if no high quality guideline exists for a given topic.

Abstract
BACKGROUND Melasma is a frequent cause of consultations at dermatology departments by dark-skinned patients in Tunisia. OBJECTIVE To investigate factors that influence melasma severity in a large Tunisian population. METHODS A total of 197 patients (188 women and 9 men), who attended Tunis Military Hospital for a consultation were included prospectively from August 2005 to August 2006. Disease severity was estimated using the Melasma Area and Severity Index (MASI). Aggravating factors were investigated using multiple logistic regressions. RESULTS Of the women included, 14% presented phototype III, 45% phototype IV and 41% phototype V; 76% presented a centrofacial melasma phenotype, 23% a malar and 1% a mandibular phenotype. About 60% developed melasma before thirty. Sun exposure was reported as a triggering factor by 51% of women and as an aggravating factor by 84%. Pregnancy was reported as an aggravating factor by 51% of women who had been pregnant, and oral contraceptive use reported by 38% of women exposed to oral contraceptives. The risk of severe melasma was about three times higher for women with age at onset under 30, phototype V and major lifetime sun exposure and about 8 times higher for women exposed to oral contraceptives. CONCLUSION This study identifies a number of factors associated with the severity of melasma. Further epidemiological studies in this type of population, in particular, to investigate triggering factors, are justified by the aesthetic damage caused by melasma in dark-skinned patients, lack of efficacy of existing treatments, non-compliance with photoprotection recommendations and the challenge of treatment.

Abstract
Abstract
Background: Taxane-induced peripheral neuropathy is a dose-limiting side effect that leads to suboptimal cancer treatment and diminished quality of life. The mode of taxane neurotoxicity is unclear, but may be through stabilization of microtubules and induction of spindle checkpoint, leading to cell cycle arrest at G2/M. Fanconi Anemia (FA) genes, including FANCD2, and FANCA, appear to be involved in G2/M phase checkpoint maintenance as well as spindle checkpoint in response to internal and external signals, such as taxane treatment. Thus, we hypothesized that variants in FA genes could impact severity of taxane-induced neuropathies.Methods: Using DNA extracted from blood collected from 893 breast cancer patients participating in a trial evaluating metronomic dosing of cyclophosphamide, doxorubicin and paclitaxel (S0221), we genotyped for single nucleotide polymorphisms (SNPs) that represent all of the variability across FANCA (44 SNPs) and FANCD2 (24 SNPs) in all race/ethnicity groups, as well as a panel of ancestry informative markers to control for potential population stratification, using Illumina GoldenGate platform. SNPs with minor allele frequency (MAF) less than 0.10 and those out of Hardy Weinberg Equilibrium (HWE) proportions (p<0.001) were removed from analyses. Ordinal regression was used to test for allelic and haplotypic association with grade 3 or 4 toxicities relative to 0, 1, and 2 toxicities, adjusting for age, genetic admixture index and treatment arm. To adjust for multiple testing, permutation analyses were performed on both single SNP and haplotype models.Results: Eighteen SNPs in FANCD2 and 38 SNPs in FANCA passed MAF and HWE proportion requirements. For FANCD2, 4 SNPs spanning 67.5 Kb (rs7648104, rs2272125 [coding SNP], rs6786638 and rs644215), were significantly associated with taxane-induced neuropathy (p<0.001) after controlling for multiple testing, with each SNP resulting in approximately a twofold increase in odds of severe taxane-induced neuropathy. Haplotype estimation showed that all 18 SNPs comprise a single haplotype. Two major (>1% frequency) haplotypes were found. The frequencies of the risk haplotype in cases (patients with grade 3 or 4 neuropathy) and controls (patients with ≤ grade 2 neuropathy) were 0.25 and 0.15, respectively. Ordinal regression analyses were highly significant (p<0.0005); patients with at least one copy of the risk haplotype had more than a twofold increased risk of grade 3 or 4 taxane-induced neuropathy (OR=2.2, 95% CI 1.44, 3.44). For FANCA, no SNPs or haplotypes were significantly associated with grade 3 or 4 neurotoxicity, either prior to or after correction for multiple testing.Conclusions: These results indicate that the Fanconi-Anemia pathway may be important for neurological sensitivity to taxanes, and that genotypic markers might be able to be used to identify patients at increased risk for severe taxane-induced neuropathy. Further studies will elucidate potential associations with survival outcomes.

Abstract
The role of targeted therapies in the treatment of women with breast cancer has been rapidly evolving. Trastuzumab, a monoclonal antibody against the human epidermal growth factor receptor 2 (HER2), was the first HER2-targeted therapy that clearly demonstrated a significant clinical benefit for women with HER2-overexpressing metastatic breast cancer (mbc). However, in recent years it has become increasingly apparent that, when trastuzumab is used in the first-line setting in combination with chemotherapy, most women eventually develop progressive disease. Determining the treatment options available to women who have progressed while on trastuzumab therapy has been hampered by a paucity of high-quality published data. In addition, with the standard use of trastuzumab in the adjuvant setting (for eligible HER2-positive patients), the role of anti-HER2 agents for patients who experience a breast cancer relapse has become a clinically relevant question. This manuscript reviews current available data and outlines suggestions from a panel of Canadian oncologists about the use of trastuzumab and other HER2-targeted agents in two key mbc indications:Treatment for women with HER2-positive mbc progressing on trastuzumab (that is, treatment beyond progression)Treatment for women with HER2-positive mbc recurring following adjuvant trastuzumab (that is, re-treatment)The suggestions set out here will continue to evolve as data and future trials with trastuzumab and other HER2-targeted agents emerge.
