Comment faciliter l'accueil des enfants asthmatiques à l'école. Le projet d'accueil individualisé (PAI)

In France, nearly 10% of children in primary school and 15% of junior high school students are asthmatic. It is important for these children to be able to continue their schooling or to be admitted [en collectivité = elsewhere?] and to have access to continued medical care or to a special diet required by their condition. The Individualized Reception Project (IRP) is aimed at establishing a partnership between parents, school-based physicians, school authorities and the children's private doctors. The proposed arrangements would allow children 1) to eat in the school cafeteria with meals prepared by their families, 2) to take their medicines orally, by inhalation and/or by injection, 3) to benefit from specific modifications that ameliorate their well-being at school, and 4) to have access to emergency care. The interministerial circular N^o 2003-135, September 8, 2003, is the text on which personnel of the National Education System, those of the Agriculture Ministry and local communities depend for this arrangement. This circular makes recommendations, but they are not obligatory. The success of the project depends on the willingness of each individual, and it should be noted that over the years, progress has been made and that collaboration between generalists, specialists, school physicians and teachers has been very productive.     

Rekonstruktion des altägyptischen Mundöffnungsgeräts Schon vor 5000 Jahren war künstliche Beatmung grundsätzlich machbar

Reproduction of an ancient Egyptian mouth-opening device raises certain technological and historical questions. The most effective variation has proven to be a device made of strip iron built exactly according to the proportions given in the Hunefer papyrus. This device allows quick and safe intubation of intubation dummy CLA 8 without a supplementary light source. Originally, the device was a metal instrument made of meteoric iron, apparently produced only in small numbers. To date, the form of production remains a mystery, since the smelting and processing of iron was totally uncommon in ancient Egypt. Based on the material structure of the device and certain portrayals in graves in Deir el-Medina, mouth-opening as it was actually performed reveals a methodology that can be reconciled with modern pre-clinical polytrauma management. In principle, this indicates that the introduction of artificial respiration thousands of years ago would have been possible.     

Mutations in the gene encoding KIAA1199 protein,an inner-ear protein expressed in Deiters’ cells and the fibrocytes,as the cause of nonsyndromic hearing loss

We report three possibly disease-causing point mutations in one of the inner-ear-specific genes, KIAA1199. We identified an R187C mutation in one family, an R187H mutation in two unrelated families, and an H783Y mutation in one sporadic case of nonsyndromic hearing loss. In situ hybridization indicated that the murine homolog of KIAA1199 mRNA is expressed specifically in Deiters cells in the organ of Corti at postnatal day zero (Pn) P0 before the onset of hearing, but expression in those cells disappears by day P7. The signal of KIAA1199 was also observed in fibrocytes of the spiral ligament and the spiral limbus through to P21, when the murine cochlea matures. Thus, the gene product may be involved in uptake of potassium ions or trophic factors with a particular role in auditory development. Although the R187C and R187H mutations did not appear to affect subcellular localization of the gene product in vitro, the H783Y mutation did present an unusual cytoplasmic distribution pattern that could underlie the molecular mechanism of hearing impairment. Our data bring attention to a novel candidate for hearing loss and indicate that screening of mutations in inner-ear-specific genes is likely to be an efficient approach to finding genetic elements responsible for deafness.Nucleotide sequence data reported herein are available in the DDBJ/EMBL/GenBank databases; for details, see the electronic eatabase section of this article.     

Urinary excretion of N-acetyl-β-d-glucosaminidase in patients after cyclosporin-treated corneal grafting

Summary Allograft rejection occurs in up to 70% of high-risk keratoplasty patients. For this reason short-term Cyclosporin treatment was administered for three months to prevent graft loss. Of 23 renal healthy patients, 19 enjoyed long-term graft acceptance. We evaluated in these patiens N-acetyl--D-glucosaminidase (NAG) excretion as a marker of renal tubular damage. All patients, except one, showed urinary NAG excretion to be within the normal range. From this we conclude that no renal tubular damage occurs after short-term Cyclosporin treatment.     

卡维地洛对原发性高血压的降压疗效及对血压变异的影响

目的：应用动态血压监测（ABPM）评价每日口服一次卡维地洛降压疗效的持续性及对血压变异的影响。方法：选择轻、中度高血压患者20例,停用所有降压药物7d,再服安慰剂14d生,对坐位舒张压为95－114mmHg,且HR≥60次／min者进行ABPM,24h平均舒张压（MDBP）≥85mmHg者,（早9时）口服卡维地洛10mg/d,共2周,对疗效满意（舒张压＜90mmHg或下降＞20mmHg)者进行ABPM,如MDBP＜85mmHg,维持原剂量不变,若MDBP≥85mmHg,每2周剂量递增10mg/d并进行疗效评价,增加至40mg/d,连用4周后进行ABPM并结束观察。结果：（1）诊室偶测血压和24h,日间,夜间动态血压平均值及相应的血压负荷均显著降低（P＜0．01）,降压总效率为85％;（2）该药的收缩压和舒张压谷／峰比值分别为79．7％和73．4％;（3）收缩压和舒张压的降压光滑指数分别为1．92和2．65;（4）治疗后24h和日间的收缩压之长时血压变异减少（P＜0．05）。结论：原发性高血压患者口服卡维地洛10mg-40mgQd,可平稳持续控制24h血压,推荐为优选的降压药物。     

238. Die glattmuskuläre Sphincterplastik

Zusammenfassung Histologische, elektronenmikroskopische, perfusionsmanometrische, mikroangiographische und elektronenmikroskopische Untersuchungen haben die Eignung der glatten Darmmuskulatur zum Schließmuskelersatz bewiesen. Der Film zeigt die Operationstechnik am Beispiel einer kontinenten Colostomie. Zwischenzeitlich ist ein überblick über 509 Patienten mit einer kontinenten Colostomie möglich. Die postoperativen funktionellen Ergebnisse waren günstig und die Komplikationsrate gering, so daß die Autoren die Verwendung von glatter Muskulatur zur Erzielung eines Schließmuskelersatzes i. B. einer Colostomie empfehlen können.     

Increase in mouse brain dopamine content by baclofen: Effects of apomorphine and neuroleptics

Baclofen, like -butyrolactone, causes a dose-dependent increase in the concentration of dopamine in the mouse brain without affecting the content of norepinephrine. This increase is antagonized by apomorphine. Haloperidol but not pimozide counteracts this effect of apomorphine and dose-dependently enhances the increase in brain dopamine produced by baclofen. The results suggest that baclofen reduces impulse flow in dopaminergic neurons in a manner similar to that produced by -butyrolactone.
