Une ascite peu ordinaire... [An Unusual Ascites...]

La découverte d'une ascite en médecine interne ambulatoire ou hospitalière est relativement fréquente. Toutefois, le diagnostic différentiel s'étend parfoisà des pathologies plus rares qu'il convient d'investiguer rapidement afin de débuter un traitement et d'améliorer le pronostic du patient. Nous présentons le cas d'un patient de 50 ans avec une ascite d'apparition progressive dans le contexte d'une carcinose péritonéale avec un diagnostic histopathologique de mésothéliome malin péritonéal.[The finding of an ascites in in- or out-patients in inner medicine is relatively frequent. However, the differential diagnosis sometimes extends in rarer pathologies which need rapid investigations to begin a treatment and improve the patient's prognosis. We present the case of a 50-year-old patient with a progressive ascites in the context of a peritoneal carcinosis due to a malignant peritoneal mesothelioma.]

Toll-interacting protein modulates colitis susceptibility in mice.

BACKGROUND: The intestinal epithelium accommodates with a myriad of commensals to maintain immunological homeostasis, but the underlying mechanisms regulating epithelial responsiveness to flora-derived signals remain poorly understood. Herein, we sought to determine the role of the Toll/interleukin (IL)-1 receptor regulator Toll-interacting protein (Tollip) in intestinal homeostasis. METHODS: Colitis susceptibility was determined after oral dextran sulfate sodium (DSS) administration or by breeding Tollip on an IL-10 background. The intestinal flora was depleted with 4 antibiotics before DSS exposure to assess its contribution in colitis onset. Bone marrow chimeras were generated to identify the cellular compartment, whereby Tollip may negatively regulate intestinal inflammation in response to DSS. Tollip-dependent epithelial barrier functions were studied in vitro by using Tollip-knockdown in Caco-2 cells and in vivo by immunohistochemistry and fluorescein isothiocyanate-labeled dextran gavage. RESULTS: Genetic ablation of Tollip did not lead to spontaneous intestinal inflammatory disorders. However, Tollip deficiency aggravated spontaneous disease onset in IL-10 mice and increased susceptibility to DSS colitis. Increased colitis severity in Tollip-deficient mice was not improved by bacterial flora depletion using broad-spectrum antibiotics. In addition, DSS exposure of bone marrow chimeric mice revealed a protective role for Tollip in nonhematopoietic cells. Knockdown of Tollip in epithelial cells led to exaggerated NFκ-B activity and proinflammatory cytokine secretion. Finally, DSS-treated Tollip mice showed enhanced intestinal permeability and increased epithelial apoptosis when compared with wild-type controls, a finding that coincided with tight junction alterations on injury. CONCLUSION: Overall, our data show an essential role for Tollip on colitis susceptibility in mice.

Flood of May 19, 1990, Along Perry Creek in Plymouth and Woodbury Counties, Iowa, HR-140, 1996

A water-surface-elevation profile and peak discharges for the flood of May 19, 1990, along Perry Creek in Plymouth and Woodbury Counties, Iowa, are presented in this report. The peak discharge for the May 19, 1990, flood on Perry Creek at 38th Street, Sioux City (06600000) is the second largest flood-peak discharge recorded at the streamflow-gaging station for the period 1939-95. The peak discharge for May 19, 1990, of 8,670 cubic feet per second, is approximately equal to the 35-year recurrence-interval discharge. The report provides information on flood stages and discharges and floodflow frequencies for streamflow- gaging stations in the Perry Creek Basin using flood information collected during 1939-95. Information on temporary bench marks and reference points established in the Perry Creek Basin during 1990-93 is also included in the report. A flood history describes rainfall conditions for the three largest floods that occurred during 1939-95 (July 1944, September 1949, and May 1990).

Qualidade dos ovos de poedeiras comerciais alimentadas com levedura seca de cana-de-açúcar

Este trabalho objetivou avaliar o efeito da adição de levedura seca (Saccharomyces cerevisiae) à dieta de poedeiras na qualidade dos ovos. Foram utilizadas 120 poedeiras comerciais com 33 semanas de idade, distribuídas em um delineamento estatístico de blocos ao acaso, com cinco tratamentos (0, 7, 14, 21 e 28% de levedura), quatro repetições e seis aves por unidade experimental. Rações isoprotéicas (18% de proteína bruta), isoenergéticas (2.800 kcal de energia metabolizável/kg), isocálcicas (3,8% Ca) e isofosfóricas (0,38% P disponível) foram formuladas à base de milho e farelo de soja. Os níveis de levedura seca não alteraram o peso do ovo (64,35± 0,85 g), a altura do albúmen (7,95±0,22 mm), a unidade Haugh (87,42±1,31), os sólidos totais da gema (50,86±0,20%), o extrato etéreo da gema (30,74±0,26%), a proteína da gema (16,92±0,16%), a gravidade específica do ovo (1,0912±0,001 g/mL), o peso da casca (6,67±0,08 g) e a espessura da casca (0,4671±0,003 mm). Foi observado efeito quadrático na variável cor da gema no terceiro ciclo de postura. A inclusão de até 28% de levedura seca nas rações intensificou a cor da gema e foi considerada uma prática viável pela análise econômica.

Adsorption of glyphosate in chilean soils and its relationship with unoccupied phosphate binding sites

The objective of this work was to investigate glyphosate adsorption by soils and its relationship with unoccupied binding sites for phosphate adsorption. Soil samples of three Chilean soils series - Valdivia (Andisol), Clarillo (Inceptisol) and Chicureo (Vertisol) - were incubated with different herbicide concentrations. Glyphosate remaining in solution was determined by adjusting a HPLC method with a UV detector. Experimental maximum adsorption capacity were 15,000, 14,300 and 4,700 mg g¹ for Valdivia, Clarillo, and Chicureo soils, respectively. Linear, Freundlich, and Langmuir models were used to describe glyphosate adsorption. Isotherms describing glyphosate adsorption differed among soils. Maximum adjusted adsorption capacity with the Langmuir model was 231,884, 17,874 and 5,670 mg g-1 for Valdivia, Clarillo, and Chicureo soils, respectively. Glyphosate adsorption on the Valdivia soil showed a linear behavior at the range of concentrations used and none of the adjusted models became asymptotic. The high glyphosate adsorption capacity of the Valdivia soil was probably a result of its high exchangeable Al, extractable Fe, and alophan and imogolite clay type. Adsorption was very much related to phosphate dynamics in the Valdivia soil, which showed the larger unoccupied phosphate binding sites. However relationship between unoccupied phosphate binding sites and glyphosate adsorption in the other two soils (Clarillo and Chicureo) was not clear.

Subplate subpopulations in the hypoxic-ischemic neonatal rat brain

Subplate neurons are among the earliest born cells of the neocortex and play a fundamental role in cortical development, in particular in the formation of thalamocortical connections. Subplate abnormalities have been described in several neuropathological disorders including schizophrenia, autism and periventricular eukomalacia (Eastwood and Harrison, Schizophr Res, 79, 2005; McQuillen and Ferriero, Brain Pathol, 15, 2005). We have identified and confirmed a range of specific markers for murine subplate using a microarray based approach and found that different subplate subpopulations are characterized by distinct expression patterns of these genes (Hoerder-Suabedissen et al., Cereb Cortex, 19, 2009). In this current study, we are making use of these markers to investigate neuropathological changes of the subplate after cerebral hypoxia-ischemia (HI) in the neonatal rat. First, we characterized the expression of a number of murine subplate markers in the postnatal rat using immunohistochemistry and in situ hybridization. While several genes (Nurr1, Cplx3, Ctgf and Tmem163) presented very similar expression patterns as in the mouse, others (Ddc, MoxD1 and TRH) were completely absent in the rat cortex. This finding suggests important differences in the subplate populations of these two rodent species. In a neonatal rat model of HI, selective vulnerability of subplate has been suggested using BrdU birthdating methods (McQuillen et al., J Neurosci, 15, 2003). We hypothesized that certain subplate subpopulations could be more susceptible than others and analyzed the above subplate markers in a similar yet slightly milder HI model. Two-day old male rat pups underwent permanent occlusion of the right common carotid artery followed by a period of hypoxia (6% O2, 1.5h or 2h) and were analyzed six days later. Preliminary counts on three subplate subpopulations (Nurr1+, Cplx3+ and Ctgf+ cells, respectively) showed similar reductions in cell numbers for all three groups. In addition, we found that the majority of cases which show changes in the subplate also exhibit lesions in the deep cortical layers VI (identified by FoxP2 expression) and sometimes even layer V (revealed by Er81 immunoreactivity), which questions the selective susceptibility of subplate over other cortical layers under the conditions we used in our model.

Diabète de type 2: n'oubliez pas les troubles du comportement alimentaire [Patient with type 2 diabetes: don't forget eating disorders!]

The coexistence of diabetes and eating disorder (ED) is more prevalent than we think; indeed it seems to occur in 10 to 20% of cases. Therefore ED deserve attention to be detected and treated in order to permit a decreased in morbidity and better outcomes in body weight loss. The association of type 2 diabetes and ED is frequently seen in younger, overweighed or obese patients suffering of at least one psychiatric co-morbidities and frequently in a difficult psychosocial setting. To succeed in ED treatment, a multidisciplinary and specialised team in eating disorder is requested, however these patients are highly fragile and complex and therapeutic failure has to be feared.

Intermittierende oder Persistierende Rhinitis bei Kindern und Jugendlichen mit Asthma: «The Swiss LARA paediatrics survey [Intermittent or persistent rhinitis in children and adolescents with Asthma: «the Swiss LARA paediatrics survey»].

Asthma and allergic rhinitis are chronic inflammatory airway diseases which often occur concomitantly. The objective of the LARA program was to identify the comorbidities and characteristics of asthma (A), intermittent or persistent rhinitis (IPR) and physician defined atopic dermatitis (AD) in 6- to 16-year old asthmatic Swiss children and adolescents. Overall, 126 general practitioners and paediatricians collected the data of 670 asthmatics. Approximately one third of the asthmatic children in Switzerland had well-controlled asthma. Almost two thirds of these asthmatics suffered from concomitant IPR. The latter presented with significantly less symptoms while the treatment rates with inhaled corticosteroids (approximately 90%) and leukotriene-receptorantagonists (approximately 50%) were comparable. However, there were almost twice as many passive smokers in the less well-controlled group. The prevalence of AD was similar in both groups. IPR and AD may play an important role as risk factors in the future development of asthma.
