Informed consent for live liver donors: A qualitative, prospective study.

Background & Aims: Adult-to-adult live donor liver transplantation (LDLT) poses serious health risks and no direct health benefits to donors. Ensuring live donors' autonomy through informed consent is critical. We assessed live liver donors' (LD) comprehension, information needs, risk perceptions, and demographics.

Culturally competent transplant program improves Hispanics' knowledge and attitudes about live kidney donation and transplant.

Context: Hispanics receive disproportionately fewer live donor kidney transplants than non-Hispanic whites. Increasing Hispanics' knowledge and changing attitudes about live kidney donation may reduce these disparities.

Objective: To evaluate the effectiveness of culturally and linguistically competent educational sessions delivered through Northwestern University's Hispanic Transplant Program.

Quality of Internet education about living kidney donation for Hispanics.

Context: Hispanics need disproportionately more kidney transplants, yet receive disproportionately fewer kidney transplants and living donor kidney transplants than non-Hispanic whites. Lack of knowledge and cultural beliefs about living kidney donation contribute to these disparities. The Internet is an optimal venue to educate underserved, low-literacy populations.

[Inter- and intrafamilial expression of cleidocranial dysostosis].

Cleidocranial dysplasia is a bony autosomal dominant disorder, defined by late closure of fontanels and sutures, clavicular aplasia or hypoplasia and supernumerary teeth. The aim of our study was to define the CBFA1 mutations in three families with cleidocranial dysplasia and to describe the phenotype expression within and between the families. While the mutation R225Q caused a similar phenotype within one family, the mutation G146R, located in the same domain, was the cause of a variable expression between two family members.

Morphological effects produced, in vitro, by ferric oxalate treatment of enamel surfaces. A preliminary SEM study.

The morphological changes produced, in vitro, by application of ferric oxalate on enamel surfaces were examined by scanning electron microscopy. Exposure of human enamel surfaces to ferric oxalate (5.3% w/w aqueous solution or added to phosphoric or citric acid) resulted in cleaned, activated enamel surfaces and a mild etching which increased surface roughness and porosity.

[The outermost enamel layer. A comparative scanning electron microscopic study].

The surface of the enamel layer was scanned in teeth of some representative animal species. We studied the structural organization of enamel at the surface of the teeth and also in subsurface. The surface layer was often described as "aprismatic".

Crystal growth on enamel in relation to acid etching.

Crystal formation may occur during etching of enamel surfaces with phosphoric acid. In this in vitro study we observed, from a morphological standpoint, some crystals left after etching, on the surfaces, using the scanning electron microscope. More often, after water-spraying, a thin generalized precipitate remains on the surface.

[Semiquantitative in vitro study of the etching of human enamel: scanning electron microscopy observations].

The efficiency of etching using lactic, citric, hydrochloric and phosphoric acids has been studied with the scanning electron microscope on 557 human enamel surfaces. A semiquantitative assessment has been performed with reference to Silverstone et al.'s classification (1975) as regards the demineralization stages of enamel prisms and to Sheykholeslam and Buonocuore's 6 points scale as regards the etching degrees.

Antinuclear antibodies detected by indirect immunofluorescence on HEp2 cells and by immunoblotting in patients with systemic sclerosis.

The HEp2 cell cultures appeared highly sensitive in detecting the antinuclear antibodies (ANAb) in systemic sclerosis, principally anticentromere antibodies of the CREST syndrome. The immunoblotting used with either complex cellular extracts from HeLa and rabbit thymus or purified nuclear components (high mobility group (HMG) proteins and histones) is able to identify precisely the ANAb targets and to contribute to diagnosis. With nuclear extracts of HeLa cells, the sera from 75.

Scanning electron microscopy of molar enamel structure of cricetodontine neogene rodents.

Ultrastructural characters of enamel were studied as a phylogenetic indicator in a family of rodent fossils: the Cricetidae. The extinct group Cricetodon-Ruscinomys is a known lineage which span 17 million of years (from -20 My to -3 My). The three-dimensional organization of enamel of the left M1 was studied in 8 cricetid species at three different levels: (1) the chewing surface; (2) the middle of the crown; (3) the cervical part, close to the root.

[Low colorectal anastomosis by the anterior perineal approach. 29 cases].

Using the combined abdominoperineal approach to the rectum through the recto-genital space, very low colo-rectal anastomosis can be performed without damaging the anal sphincter. Twenty-nine patients were operated upon by this procedure for malignant or benign disease of the lower two-thirds of the rectum: there was 2 failure; 6 patients developed transient perineal fistula; 27 patients now have normal anal continence. This technique has been considerably facilitated, notably in males, by stapled anastomosis.

[Cystohepatic ducts. Surgical problems and review of the literature. About 10 operated cases (author's transl)].

The authors are reporting 10 cases of operated cystohepatic ducts. In each case there is a unic duct, leading five times in the gallbladder, and once in the cystic duct. In 8 cases this abnormality was shown intraoperatively.
