Abstract
Williams-Beuren syndrome is a well-known microdeletion syndrome with a recognizable clinical phenotype. The subtle phenotype of the reciprocal microduplication of the Williams-Beuren critical region has been described recently. We report seven further patients, and a transmitting parent, with 7q11.23 microduplication. All our patients had speech delay, autistic features and facial dysmorphism consistent with the published literature. We conclude that the presence of specific dysmorphic features, including straight, neat eyebrows, thin lips and a short philtrum, in our patients with speech delay and autistic features provides further evidence that the children with 7q11.23 microduplication have a recognizable phenotype.

Abstract
BACKGROUND Myocardial infarction (MI) is characterized by irreversible loss of cardiomyocytes, resulting in impaired ventricular function. Stem cell therapy using autologous progenitor cells has emerged as a promising approach. Experimental studies have demonstrated that highly selected hematopoeitic stem cells, which are characterized by the presence of the surface markers CD34 and CD133, may contribute to repair of the acutely infarcted myocardium by inducing neovascularization, inhibiting apoptosis, and promoting cardiomyogenesis. We sought, to evaluate the intracoronary injection of CD133+ stem cells for cardiac repair in patients with dysfunctional myocardium after an acute MI. PATIENTS AND METHODS In this Canadian randomized, double-blind, placebo-controlled, Phase I-II study ("COMPARE-AMI"), we are evaluating the feasibility, safety, and efficacy of intracoronary injection of selected CD133+ stem cells for cardiac repair in patients with impaired cardiac function after successfully stented acute MI. Since November 2007, we have enrolled 14 patients in the study. Their mean age was 50.5 +/- 9.1 years, including 93% men. The culprit lesion was always on the left anterior descending artery (LAD). Their maximum troponin and CKMB levels were 8.4 +/- 6.1 microg/L and 322 +/- 225 U/L, respectively. RESULTS Compared with the baseline, we observed a significant 8.7% improvement in left ventricular ejection fraction at 4 months follow-up, namely, from 41.3 +/- 5.5% to 50.0 +/- 8.2% (n = 7; P = .008). There were no protocol-related complications. Our trial is designed to recruit 40 patients who are randomized 1:1 to receive CD133+ cells or placebo. PERSPECTIVE There is a need to seek out new therapeutics for the treatment of ischemic heart disease addressing the early loss of viable myocytes. Stem cell transplantation has shown early promise; this appraisal needs well-designed, controlled studies.

Abstract
The interactions that may occur between microorganisms in different ecosystems have not been adequately studied yet. We investigated yeast-bacterium interactions in a synthetic medium using different culture associations involving the yeast Yarrowia lipolytica 1E07 and two bacteria, Staphylococcus xylosus C2a and Lactococcus lactis LD61. The growth and biochemical characteristics of each microorganism in the different culture associations were studied. The expression of genes related to glucose, lactate, and amino acid catabolism was analyzed by reverse transcription followed by quantitative PCR. Our results show that the growth of Y. lipolytica 1E07 is dramatically reduced by the presence of S. xylosus C2a. As a result of a low amino acid concentration in the medium, the expression of Y. lipolytica genes involved in amino acid catabolism was downregulated in the presence of S. xylosus C2a, even when L. lactis was present in the culture. Furthermore, the production of lactate by both bacteria had an impact on the lactate dehydrogenase gene expression of the yeast, which increased up to 30-fold in the three-species culture compared to the Y. lipolytica 1E07 pure culture. S. xylosus C2a growth dramatically decreased in the presence of Y. lipolytica 1E07. The growth of lactic acid bacteria was not affected by the presence of S. xylosus C2a or Y. lipolytica 1E07, although the study of gene expression showed significant variations.

Abstract
BACKGROUND A 23-year-old male was referred to our clinic with diagnosis of idiopathic isolated growth hormone deficiency. A detailed family history revealed short stature and swelling of legs which only affected females in four generations of his family. METHODS Combined pituitary function tests revealed growth hormone deficiency, secondary hypothyroidism and hypoprolactinemia in the proband. His mother had hypoprolactinemia and growth hormone deficiency. A diagnosis of inherited combined pituitary deficiency due to a PIT-1 mutation was suspected in view of the short stature with associated multiple pituitary hormone deficiencies. RESULTS A mutation was identified in PIT-1 (POU1F1), 196C>T, which produces the amino acid change P24L in exon 1. The mutation was also found in the mother of the proband but not in his phenotypically normal half-sister. CONCLUSION The case shows a novel association of two rare conditions Pit-1 mutation and lipoedema in a family that has not been described before. It also allows formulation of hypothesis on the interaction of growth hormone and sex steroids resulting in abnormal fat distribution in predisposed subjects at the time of puberty.

Abstract
We report a series of eight patients with the Say/Barber/Biesecker/Young-Simpson (SBBYS) type of Ohdo syndrome, which is the largest cohort described to date. We expand on the type, frequency and severity of the clinical characteristics in this condition; comment on the natural history of Ohdo syndrome and further refine previously published diagnostic criteria. Cytogenetic investigations and microarray CGH analysis undertaken in this cohort of patients failed to identify a chromosomal aetiology. It remains possible that this rare condition is heterogeneous and therefore caution must be undertaken during counselling until the underlying genetic mechanism(s) is (are) identified.

Abstract
The aim of the study was to determine the prevalence of anti-hepatitis A virus (anti-HAV) antibodies among 172 children with chronic liver disease, and to calculate the cost-effectiveness of prescreening prior to hepatitis A vaccination. Anti-HAV antibodies were positive in 85.1%. However, seroprevalence of anti-HAV antibodies was 62.1% in children < 5 years and 94.4% in children 5+ years. We conclude that while it is cost-effective to do prescreening before hepatitis A vaccination for children with chronic liver disease aged 5+ years, prescreening might not be cost-effective in those aged < 5 years.

Abstract
Effect of smoking and environmental noise on hearing impairment was investigated in 440 people aged 21-50 years living in Beirut. Participants were divided into 4 groups: nonsmokers and smokers living in noisy areas (70-90 dBA) and non-smokers and smokers living in quiet areas (45-55 dBA). Smoking was associated with hearing loss at 8000 Hz, in both bivariate and multivariate analysis. An additive interaction at high frequencies (mostly at 8000 Hz) between smoking and noise appeared after age 40 years. At age 21-39 years, neither smoking nor environmental noise had a significant adverse effect on hearing capacity at low frequencies.
