[The five-word test in memory deficiency].

The 5-Word test is a bedside memory test with free and cued selective recollection. Here, we evaluated its reliability Belgian French speakers. Five groups were studied : normal subjects, depressive patients, patients with AD, patients with vascular dementia and 47 patients for a validation of a logistic model. The results of the 5-Word test with the MMSE, both values were included as variables in a logistic regression model. The probability of diagnosis of AD and dementia can be calculated and used prospectively for assessment of new cases in a validation study. The importance of the study of free and cued response during immediate and delayed recall was assessed by variance analysis in 4 groups. A third order interaction (p < 0.001) was observed between the normal and AD groups, the normal and vascular dementia (VD) groups and between AD and VD groups. With this initial model, 98% of the 62 normal subjects and the 57 patients with AD were correctly classified (p < 0.001). For AD diagnosis at the onset, the sensitivity of the MMSE is increased when it is associated with the 5-Word. This low-tech bedside method associating the 5-Word test and MMSE has a good specificity for the diagnosis of AD. It is very useful for screening a population of patients at the onset of cognitive and memory deficiency and for selecting the patients requiring an examination at a memory clinic.

A new species and three new combinations in Cyphellophora, with a note on the taxonomic affinities of the genus, and its relation to Kumbhamaya and Pseudomicrodochium.

Cyphellophora guyanensis sp. nov., isolated from leaf litter in French Guyana, is described and illustrated. This fungus is characterized by ampulliform to flask-shaped phialides, with a conspicuous, funnel-shaped collarette, and nearly straight to falcate or slightly sigmoid, (2-)3-6 septate conidia. Cyphellophora guyanensis is compared to the other Cyphellophora species, and the latter genus is compared to Kumbhamaya and Pseudomicrodochium. Kumbhamaya indica, P. fusarioides, and P. suttonii are transferred to Cyphellophora. The phylogenetic relationships of Cyphellophora with other genera of ascomycetes and related mitosporic fungi were inferred from the analysis of the partial nuclear ribosomal DNA SSU sequences data. The analysis supports a placement of Cyphellophora in Chaetothyriales, and probably in the Herpotrichiellaceae

Comparison of two techniques for diagnosis of giardiasis in dogs.

Giardiasis is an intestinal parasitosis affecting dogs and able to infect human beings. Its diagnosis can not be done with the only clinical signs, the main of which is non characteristic diarrhoea. It implicates to perform further tests to detect the parasite. The zinc sulfate concentration technique (ZSCT) is the more effective one if performed on two or three successive days. Fecal ELISA kits have been developed to detect Giardia in humans and were found to be less sensitive than the ZSCT in dogs. In this study, we used 30 infected Beagles to compare the sensitivity of one, two or three fecal examinations following ZSCT and one or two ELISA tests. We conclude that if a single ZSCT is insufficient, two or three ZSCT and one or two ELISA using the commercial kit ProSpecT Giardia have almost the same sensitivity.

Alport syndrome and conjunctival telangiectasia.

We report a patient with ocular abnormalities due to Alport syndrome. Considerable improvement of visual acuity was obtained following ocular lens extraction with foldable lens implantation in the right eye to compensate the effect of the lenticonus anterior. The presence of conjunctival telangiectasia is a new clinical finding in a patient with Alport syndrome.

A Bacillus thuringiensis insecticidal crystal protein with a high activity against members of the family Noctuidae.

The full characterization of a novel insecticidal crystal protein, named Cry9Ca1 according to the revised nomenclature for Cry proteins, from Bacillus thuringiensis serovar tolworthi is reported. The crystal protein has 1,157 amino acids and a molecular mass of 129.8 kDa. It has the typical features of the Lepidoptera-active crystal proteins such as five conserved sequence blocks. Also, it is truncated upon trypsin digestion to a toxic fragment of 68.7 kDa by removal of 43 amino acids at the N terminus and the complete C-terminal half after conserved sequence block 5. The 68.7-kDa fragment is further degraded to a nontoxic 55-kDa fragment. The crystal protein has a fairly broad spectrum of activity against lepidopteran insects, including members of the families Pyralidae, Plutellidae, Sphingidae, and Noctuidae. A 50% lethal concentration of less than 100 ng/cm2 of diet agar was found for diamondback moth, European corn borer, cotton bollworm, and beet armyworm. It is the first insecticidal crystal protein with activity against cutworms. No activity was observed against some beetles, such as Colorado potato beetle. The protein recognizes a receptor different from that recognized by Cry1Ab5 in Ostrinia nubilalis and Plutella xylostella. In Spodoptera exigua and P. xylostella, it binds to a receptor which is also recognized by Cry1Cax but with a lower affinity. In these insects, Cry1Cax probably binds with a higher affinity to an additional receptor which is not recognized by Cry9Ca1. Elimination of a trypsin cleavage site which is responsible for the degradation to a nontoxic fragment did result in protease resistance but not in increased toxicity against O. nubilalis.
