Abstract
Abstract
Fear of high local recurrence rate associated with immediate breast reconstruction (IBR) following total mastectomy for breast cancer might be a contributing factor to the low rate of immediate reconstruction performed in Quebec. The aim of this study was to demonstrate the oncological safety of total mastectomy with immediate breast reconstruction.
A retrospective chart review of all patients who underwent total mastectomy with immediate breast reconstruction at the University of Montreal Hospital Center between 2006 and 2015 was performed.
375 patients (420 cases) met the inclusion criteria. The mean age was 51.5 years (25-77). The median follow-up was 45.6 months (0.4-115.2). Clinical cancer staging was done according to the American Joint Committee on Cancer (AJCC) criteria. 349 cases (83.1%) were classified as Stage < cIIb and 71 cases (16.9%) as ≥ cIIb. 73 patients (19.5%) received neoadjuvant chemotherapy, 113 (30.1%) received adjuvant chemotherapy and 91 (21.7%) received postoperative radiotherapy. Only 4 patients (3.5%) had a significant delay in receiving adjuvant chemotherapy and 4 patients (4.4%) had a delay in initiation of radiotherapy. In total, there were 12 (2.6%) local recurrences and 29 (7.7%) distant recurrences.
The results of this study demonstrate a low rate of local recurrence that is comparable to the current litterature. Total mastectomy in association with immediate breast reconstruction is therefore an oncologically safe approach for the treatment of breast cancer and should be more widely adopted by medical centers throughout Quebec.

Abstract
OBJECTIVE To evaluate several alternative measures of forced expiratory volume in 1 second percent predicted (FEV1 %pred) variability as potential predictors of future FEV1 %pred decline in patients with cystic fibrosis. STUDY DESIGN We included 13,827 patients age ≥6 years from the Epidemiologic Study of Cystic Fibrosis 1994-2002 with ≥4 FEV1 %pred measurements spanning ≥366 days in both a 2-year baseline period and a 2-year follow-up period. We predicted change from best baseline FEV1 %pred to best follow-up FEV1 %pred and change from baseline to best in the second follow-up year by using multivariable regression stratified by 4 lung-disease stages. We assessed 5 measures of variability (some as deviations from the best and some as deviations from the trend line) both alone and after controlling for demographic and clinical factors and for the slope and level of FEV1 %pred. RESULTS All 5 measures of FEV1 %pred variability were predictive, but the strongest predictor was median deviation from the best FEV1 %pred in the baseline period. The contribution to explanatory power (R(2)) was substantial and exceeded the total contribution of all other factors excluding the FEV1 %pred rate of decline. Adding the other variability measures provided minimal additional value. CONCLUSIONS Median deviation from the best FEV1 %pred is a simple metric that markedly improves prediction of FEV1 %pred decline even after the inclusion of demographic and clinical characteristics and the FEV1 %pred rate of decline. The routine calculation of this variability measure could allow clinicians to better identify patients at risk and therefore in need of increased intervention.

Abstract
The total structure factors as well as the total pair correlation functions of amorphous Mg84Ni16 and Mg30Ca70 were determined by X-ray diffraction. The Mg-Ni glass shows rather strong chemical short range ordering. By Gaussian fit of the total pair correlation function partial coordination numbers and atomic distances were obtained. Similar surrounding of the Ni atoms in the amorphous phase and in crystalline Mg2Ni was found. The structural features of the Mg-Ca glass differ from those of the Mg-Ni glass

Abstract
The total structure factors as well as the total pair correlation functions for amorphous Mg85.5Cu14.5 (by neutron and X-ray diffraction) and for amorphous Mg70Zn30 (by X-ray diffraction) were determined. Both alloys show similar chemical short range order effects. From the total pair correlation function of the Mg85.5Cu14.5 glass, partial coordination numbers and atomic distances could be extracted. Comparison with the structure of crystalline Mg2Cu suggests that the short range order around the copper atoms is similar in the amorphous and the crystalline phase. The densities of both amorphous alloys were measured yielding negative excess volumina.

Abstract
The binary molten alloys Mn74Si26 and Mn33.5Si66.5 have been investigated by means of X-ray diffraction. The total structure factors as well as the total pair correlation functions were evaluated. The interatomic distances and total coordination numbers are given. The structural results for Mn74Si26 were compared to those for amorphous Mn74Si23P3 and for a tetrahedral packing model. A pronounced shoulder on the second maximum of the structure factor, which normally is characteristic for the curves obtained with amorphous substances was observed for the Mn74Si26 melt. With the Mn33.5Si66.5 melt, however, this feature cold not be observed. Since with this concentration no glass forming by melt spinning is possible, a correlation between the shape of the second maximum of a total structure factor and the glass forming ability of the corresponding melt is suggested.

Abstract
The structural results for molten Ni81B19 are compared with the structure of a metallic glass which can be obtained at the same composition by rapid quenching the melt within a melt spin equipment. Structural relationship exists between the molten and the amorphous state. This feature follows especially from a marked asymmetry of the second maximum of the structure factor obtained from the melts, to which corresponds the splitting up of the second maximum in the total structure factor of the amorphous specimen. With the Ni53B47- and the Ni43B57 -melts which don't belong to the concentration range of glass-forming Ni-B-melts no peculiarities in the range of the second maximum of the structure factor were observed.

Abstract
We hypothesized that exemestane (EXE) would reduce mammographic breast density and have unique effects on biomarkers of bone and lipid metabolism. Healthy postmenopausal women were randomized to EXE (25 mg daily) or placebo (PLAC) for 12 months and followed for a total of 24 months. The primary endpoint was change in percent breast density (PD) between the baseline and 12-month mammograms and secondary endpoints were changes in serum lipid levels, bone biomarkers, and bone mineral density (BMD). Ninety-eight women were randomized (49 to EXE; 49 to PLAC) and 65 had PD data at baseline and 12 months. Among women treated with EXE, PD was not significantly changed from baseline at 6, 12, or 24 months and was not different from PLAC. EXE was associated with significant percentage increase from baseline in N-telopeptide at 12 months compared with PLAC. No differences in percent change from baseline in BMD (lumbar spine and femoral neck) were observed between EXE and PLAC at either 12 or 24 months. Patients on EXE had a significantly larger percent decrease in total cholesterol than in the PLAC arm at 6 months and in HDL cholesterol at 3, 6, and 12 months. No significant differences in percent change in LDL or triglycerides were noted at any time point between the two treatment arms. EXE administered for 1 year to healthy postmenopausal women did not result in significant changes in mammographic density. A reversible increase in the bone resorption marker N-telopeptide without significant change in bone specific alkaline phosphatase or BMD during the 12 months treatment period and 1 year later was noted. Changes in lipid parameters on this trial were modest and reversible.

Abstract
In an ethnically-homogeneous population, it is valuable to identify founder mutations in cancer-predisposing genes. Founder mutations have been found in four breast-cancer-predisposing genes in French-Canadian breast cancer families. The frequencies of the mutant alleles have been measured neither in a large series of unselected breast cancer patients from Quebec, nor in healthy controls. These estimates are necessary to measure their contribution to the hereditary burden of breast cancer in Quebec and to help develop genetic screening policies which are appropriate for the province. We studied 564 French-Canadian women with early-onset invasive breast cancer who were treated at a single Montreal hospital. Patients had been diagnosed at age 50 or less, and were ascertained between 2004 and 2008. We screened all 564 patients for nine founder mutations: four in BRCA1, three in BRCA2 and one each in PALB2 and CHEK2. We also studied 6433 DNA samples from newborn infants from the Quebec City area to estimate the frequency of the nine variant alleles in the French-Canadian population. We identified a mutation in 36 of the 564 breast cancer cases (6.4%) and in 35 of 6443 controls (0.5%). In the breast cancer patients, the majority of mutations were in BRCA2 (54%). However, in the general population (newborn infants), the majority of mutations were in CHEK2 (54%). The odds ratio for breast cancer to age 50, given a BRCA1 mutation, was 10.1 (95% CI: 3.7-28) and given a BRCA2 mutation was 29.5 (95% CI: 12.9-67). The odds ratio for breast cancer to age 50, given a CHEK2 mutation, was 3.6 (95% CI: 1.4-9.1). One-half of the women with a mutation had a first- or second-degree relative diagnosed with breast or ovarian cancer. Thus, it can be concluded that a predisposing mutation in BRCA1, BRCA2, CHEK2 or PALB2 is present in approximately 6% of French-Canadian women with early-onset breast cancer. It is reasonable to offer screening for founder mutations to all French-Canadian women with breast cancer before age 50. The frequency of these mutations in the general population (0.5%) is too low to advocate population-based screening.

Abstract
Abstract
Background: In an ethnically-homogeneous population, it is valuable to identify founder mutations in cancer-predisposing genes. Founder mutations have been found in four breast cancer predisposing genes in French-Canadian breast cancer families. The frequencies of the mutant alleles have not been measured in a large series of unselected breast cancer patients from Quebec, nor in healthy controls. These estimates are necessary to measure their contribution to the hereditary burden of breast cancer in Quebec and to help develop genetic screening policies which are appropriate for the province.Methods: We studied 564 French-Canadian women with early-onset invasive breast cancer who were treated at a single Montreal hospital. Patients had been diagnosed at age 50 or less, and were ascertained between 2004 and 2008. We screened all 564 patients for nine founder mutations; four in BRCA1, three in BRCA2 and one each in PALB2 and CHEK2. We also studied 6433 DNA samples from newborn infants from the Quebec City area to estimate the frequency of the nine variant alleles in the French-Canadian population.Results: We identified a mutation in 36 of the 564 breast cancer cases (6.4%) and in 35 of 6443 controls (0.5%). In the breast cancer patients, the majority of mutations were in BRCA2 (54%). However, in the general population (newborn infants), the majority of mutations were in CHEK2 (54%). The odds ratio for breast cancer to age 50, given a BRCA1 mutation was 10.1 (95% CI: 3.7 to 28) and given a BRCA2 mutation was 29.5 (95% CI: 12.9 – 67). The odds ratio for breast cancer to age 50, given a CHEK2 mutation was 3.6 (95% CI: 1.4 – 9.1). One-half of the women with a mutation had a first or second-degree relative diagnosed with breast or ovarian cancer.

Abstract
e12028 Background: Evaluating the axillary lymph nodes is extremely important in the management of breast cancer, with the recent improvement in histopathology techniques detection of micro-metastasis and even isolated cancer cells (ITC) in a setting of sentinel lymph node examination is feasible. In this study we aim to compare the outcome and significance of; positive SLN for macro versus Micro-metastasis, and ITCs. Methods: We reviewed all the patients who had SLN for breast cancer of stage T 1–2 between April 2006 and November 2008. Identifying all those who had positive macro-metastasis, micro-metastasis, or isolated tumor cells, pathology results of the full axillary LN dissection was evaluated for each type. Results: 350 patients had SLN of these 226 had a disease of T1–2, thirty seven patients (16.3%) had full axillary dissection, of these 27/37 had positive SLN for macro-metastasis, six had micro-metastasis and 3/37 had only ITCs. The presence of other LN metastasis was detected in 8 cases (21.6%); all of them were in the macro-metastasis group. No metastasis was found in either the micro-metastasis or the ITC groups. The ITC was only detected with DCIS; while micro-metastasis was present in DCIS or IDC. No relation was identified between the histopathology grade with ITC or micro-metastasis. Conclusions: Our findings did not show any presence of lymphatic metastasis after full axillary dissection, in case of positive micro-metastasis or ITCs in SLN, compared to the group of macro-metastasis. No significant financial relationships to disclose.

Abstract
OBJECTIVE The purpose of this study is to evaluate the validity and reliability of scintimammography with technetium-99m (99mTc)-labeled sestamibi as an adjunct radiodiagnostic agent in the diagnosis of breast cancer. METHODS This is a multicenter prospective cohort clinical trial that was initiated in June 1999 and will terminate May 2001. All patients with a physical or mammographic finding visiting any of the participating clinics are enrolled in the study. Patients who are younger than 18 years, pregnant, not willing to sign the consent form, or who have undergone an invasive procedure on the breast 30 days or less before scintimammography are excluded. At the time of the first interim report, 633 patients had been recruited from six Canadian centers. To date complete data have been collected for 530 patients. RESULTS The mean (SD) age of the patients is 56 (12) years with a range between 24 and 85. There were 122 (23%) of the women in the sample who were postmenopausal and 36 (7%) who were perimenopausal. Breast density was graded as dense for 127 (24%), normal for 260 (50%), and fatty for 138 (26%). Of the 530 women in the study 156 (29%) had a palpable mass at physical examination. The mammographic results were classified as 76 (14%) breast imaging reporting and data system (BIRADS) 5, 60 (11%) BIRADS 4, 70 (13%) BIRADS 3 and the remaining BIRADS 2 or 1. The scintimammography results were positive for 118 (23%) of the patients and negative for 412 (78%). The histopathology showed malignant breast disease for 66 (12.5%) of the patients in the sample. Sensitivity and specificity of scintimammography for the detection of breast cancer was estimated 90.9% and 87.5%, respectively. A positive predictive value (PPV) of 50.8% with a negative predictive value of 98.5% and an accuracy of 87.5% were calculated. The PPV is interpreted as the posttest probability of disease given a positive test result. In this sample the pretest probability of disease would be best estimated by the prevalence of disease, which is equal to 12.5%. A positive scintimammography result would change the estimated probability to 51%, which is equivalent to a 400% change from the pretest value. Therefore a positive scintimammography result significantly increases our ability to predict the presence of malignant disease in this population. CONCLUSION The interim results of the present study suggest that scintimammography with 99mTc-sestamibi is accurate and potentially useful as an adjunct to mammography for the detection of breast cancer.

Abstract
GOAL Evaluation of interferon alpha-2b adjuvant treatment (INF alpha-2b) toxicity by monitoring biologic parameters in patients with stage III melanoma. METHOD Between January 7th till October 29th 1998, we administered 674 injections of INF alpha-2b to eight patients who previously had undergone surgery for stage III melanoma. Patients received 20 MU/m2/d IV for a month and 10 MU/m2/d sub-cutaneously three time a week for 48 weeks. All these patients were followed with at least one complete blood count and hepatic profile every week. Interferon alpha-2b doses were changed accordingly. RESULTS Patients received on average 51.5% of the total dose. Doses were decreased in patients with neutropenia or hepatic profiles anomalies. Only one patient could received 100% of the total regimen. In four patients treatment was discontinued. In three out of four patients this was due to disease progression, and in one out of four patients this was due to hepatic toxicity. CONCLUSION INF alpha-2b is less well tolerated than initially thought. Dosage was frequently decreased due to hematologic and hepatic toxicities. This could compromise the treatments efficacity. The minimal dose required to obtain an optimal response will thus have to be defined.

Abstract
BACKGROUND Asthma is a major cause of morbidity in childhood, restricting activity and causing absences from school. Theophylline, although effective in managing chronic asthma, has been reported to cause deficits in cognitive functioning and school performance. We therefore examined the effect of asthma and its treatment on academic achievement in a large, representative population of school-age children; matched sibling controls were used for comparison. METHODS We identified 255 consecutive children with asthma (mean age, 12.0 years) who had taken nationally standardized scholastic achievement tests administered routinely by the schools. One hundred one of these children had siblings without asthma with whom comparisons could be made in reading, mathematics, and a composite measure of achievement. RESULTS Academic achievement among the children with asthma was similar to normative standards in Iowa and higher than national standards, as reflected in a mean composite T-score of 57.1 (expected mean [+/- SD], 50 +/- 10). For the 101 children with sibling controls, composite T-scores were 58.3 for the children with asthma and 57.5 for the siblings. Eighty-five of these 101 children with asthma were receiving daily maintenance medication for chronic asthma; 72 of these were receiving theophylline. The mean composite T-scores were 58.5 for the theophylline-treated patients and 58.4 for their siblings without asthma. None of the differences between the children with asthma and the sibling controls were statistically significant. CONCLUSIONS Academic achievement among children with asthma, at least those whose status is closely monitored in a structured treatment program, generally appears to be unaffected by asthma or by its treatment with appropriate doses of theophylline.

Abstract
Extrapulmonary effects of alternate-day prednisone and inhaled beclomethasone dipropionate therapy were examined in 24 and 32 children with asthma, respectively. Early morning serum cortisol values were significantly lower among patients receiving alternate-day prednisone than among patients receiving inhaled beclomethasone dipropionate and control subjects at 24 hours but not at 48 hours after an alternate-day prednisone dose. Urinary-free cortisol output during the second 24 hours of the alternate-day prednisone regimen were similar to values among patients receiving inhaled beclomethasone and were significantly lower than among control subjects for both groups. Mean heights among patients before being placed on maintenance corticosteroids were at the thirty-fifth percentile and were similar for both regimens. This was significantly lower than initial measurements for control subjects who, on average, were near the fiftieth percentile for both children with asthma not requiring maintenance corticosteroids and normal healthy Iowa children. Mean heights for both corticosteroid-treated groups remained at the thirty-fifth percentile after more than a 2-year average duration of follow-up. Heights of children with chronic asthma not requiring maintenance corticosteroids were initially significantly higher (fifty-first percentile) than the patients who subsequently required maintenance corticosteroids and increased significantly to the sixty-first percentile during a mean 2.7-year follow-up. Heights of healthy Iowa children remained near the fiftieth percentile during a mean 7-year follow-up. Disproportionate weight gain, although it was not consistently present, was significantly more likely with the alternate-day prednisone. Other extrapulmonary effects of the corticosteroid regimens appeared not to be of clinical importance during the time period of the study.

Abstract
The effect of high orally administered doses of prednisone for 1 week early in the course of an acute exacerbation of asthma incompletely responsive to bronchodilators was examined in 41 patients randomly assigned to receive either prednisone or an identical appearing placebo. All 22 of the patients who received prednisone improved during the week of treatment, although one had a subsequent exacerbation 5 days after discontinuing the study medication. Of the 19 who received placebo, eight required rescue intervention (P = less than 0.004) in association with continued symptoms, increased frequency of metered-dose inhaler use, and decreased pulmonary function; the other 11 improved at about the same rate as those who received prednisone. Although the mean initial FEV1 was suggestively lower among those who did not improve and required intervention, there was considerable overlap with those who improved spontaneously, and no reliable distinguishing characteristics were found at entry into the study that could serve as predictors of those who would or would not improve spontaneously. There were no clinically important adverse effects from the prednisone. Because continued symptoms of asthma often result in emergency care or hospitalization, these data support early intervention with orally administered prednisone for acute exacerbations that do not respond fully to bronchodilators, at least in those patients with a prior history of a protracted course or emergency care.

Abstract
The cerebrospinal fluid (CSF) pharmacokinetics of cytosine arabinoside (Ara-C) was determined in 8 patients with metastatic cancer in the central nervous system. High dose (3 gm/M2) one-hour intravenous infusions of Ara-C were given with serial CSF sampling obtained from indwelling Ommaya reservoirs. CSF was analyzed by high pressure liquid chromatography. Mean Ara-C elimination half life of 140 minutes in CSF was eight times longer than that in plasma. The peak mean CSF concentration of Ara-C (2.1 micrograms /ml) was about 7% of the plasma concentration (30 micrograms/ml). A total of 28 treatment courses were administered with minimal hematopoietic, gastrointestinal and neurological toxicities. A schedule of administration of 2 high-dose treatments 12 hours apart repeated every two weeks should maintain cytotoxic CSF concentrations which could prove useful in the management of CNS leukemia and lymphoma.

Abstract
Thirty patients with previously treated small cell lung cancer received salvage combination chemotherapy with etoposide and cisplatin. Two complete and six partial responses were observed, for a major response rate of 27%. Responses occurred promptly and sustained palliation was achieved among responders. Myelosuppression was the major dose-limiting toxic effect. A schedule of etoposide (115 mg/m2 iv on Days 1-3) and cisplatin (25 mg/m2 iv on Days 1-3 every 28 days) is recommended for further clinical trials.

Abstract
Infections occurring among hospitalized young infants were surveyed for 24 months. Almost 10% of the 7,339 infants received antimicrobial therapy for five or more days for suspected community-acquired infections. Infants admitted directly to the normal-newborn nursery acquired infections at a rate of 0.6 per 100, whereas infants admitted to intensive care nurseries acquired infections at a rate of 16.9 per 100 infants. Bacteremia in association with nosocomial infection occurred frequently. The pathogens associated with community-acquired and nosocomial infections are different. Species of streptococci and relatively antibiotic-susceptible Enterobacteriaceae predominate as pathogens associated with infections in previously nonhospitalized infants. Organisms acquired in the hospital tend to be more antibiotic resistant.
