Élaboration d’un guide d’information SOR SAVOIR PATIENT à l’usage des personnes malades et de leurs proches sur la vie intime et sexuelle pendant et après un cancer : l’étape d’état des lieux

Since 1998, the French National Federation of Comprehensive Cancer Centres (FNCLCC) has led an information program dedicated to patients and their relatives: the SOR SAVOIR PATIENT (SSP) program. The program is provided by the FNCLCC, the twenty French regional cancer centres (CLCC), the National League Against Cancer (LCC), the French National Cancer Institute (INCa), the French Hospital Federation (FHF), the National Oncology Federation of Regional and University Hospitals (FNCCHRU), the French Oncology Federation of General Hospitals (FFCHG), the National Private Hospital Union for Oncology (UNHPC), the International Union Against Cancer (UICC) and a large number of learned societies. The methodology of the program adheres to the quality criteria established for publishing documents containing information for patients. Issues related to the sexual health of cancer patients and their partners too often remain underestimated and even completely neglected by health professionals, although healthcare providers are increasingly interested in this area and patients frequently confront them with questions about this aspect of their lives. The development of an SOR SAVOIR PATIENT informational guide on the various issues related to sexuality during and after cancer treatment constitutes a first step in addressing the needs of cancer patients and others concerned. This article describes the first stage in the development of a specific SOR SAVOIR PATIENT guide that focuses on the general availability of informational material in French on the sexual health of patients and their partners during and after cancer treatment.     

Molecular cloning and characterization of a novel ABC transporter gene in the human pathogen Trichophyton rubrum.

A gene encoding an ABC transporter in the dermatophyte Trichophyton rubrum, TruMDR1, was cloned by PCR using degenerate primers. The open reading frame of TruMDR1 is 4838 bp long and the deduced amino acid sequence shows high homology with ABC transporters involved in drug efflux of other fungi. The effect of chemicals on the expression level of mRNAs of this gene was analysed by Northern blot. An increase in expression level was observed when the fungus was exposed to ethidium bromide, ketoconazole, cycloheximide, fluconazole, griseofulvin, imazalil and itraconazole, suggesting the participation of this gene in drug efflux in this dermatophyte. The identification of a gene potentially involved in cellular detoxification in a pathogenic fungus is the first step towards knowing molecular events related to antifungal resistance.     

Amyloidosis in familial Mediterranean fever patients: correlation with MEFV genotype and SAA1 and MICA polymorphisms effects

Background

Hemihyperplasia (hemihypertrophy) is defined as asymmetric body overgrowth of one or more body parts. Hemihyperplasia can be isolated or be part of well-defined syndromes such as in the case of Beckwith-Wiedemann syndrome (BWS). Isolated hemihyperplasia is usually sporadic, but a number of familial occurrences have been described.

Case presentation

We describe a Tunisian family in which three maternal cousins and their maternal grandfather present with isolated hemihyperplasia.

Conclusions

The etiology of isolated hemihyperplasia is unknown although in BWS, genomic imprinting has been shown to play a role in the asymmetric overgrowth. Given the similarity between these two conditions, it is possible that both may share a common pathogenesis. We also discuss the possible genetic mechanisms leading to the production of hemihyperplasia in this family.     

Prominent intrasinusoidal infiltration of the bone marrow by mantle cell lymphoma

Intrasinusoidal infiltration of bone marrow (BM) may accompany several malignant lymphoproliferative disorders. In small B-cell lymphomas, this pattern is considered specific for splenic marginal zone lymphoma (SMZL) when exclusive or prominent, although it may occur in other subtypes of non-Hodgkin's lymphomas (NHLs) as a minor feature. Here we report 2 cases of mantle cell lymphoma (MCL) with a prominent intrasinusoidal BM infiltration pattern. Both patients presented with massive splenomegaly and peripheral blood involvement characterized by markedly atypical lymphocytes, but no lymphadenopathy. The cytological features and the phenotype of the lymphoma cells were diagnostic of MCL. The malignant B cells showed coexpression of B-cell markers (CD20+ and CD79a+), CD5 antigen, and cyclin D1 by immunohistochemistry. We discuss the specificity of an intrasinusoidal growth pattern in the bone marrow, emphasizing the importance of using a broader immunohistochemical panel in the differential diagnosis of intrasinusoidal BM infiltration by NHL.     

Group‐specific component (GC) in curiaú and pacoval,two african‐derived brazilian populations

The group‐specific component (GC) system is of interest in anthropological genetic studies because the distribution of its subtypes distinguishes among major ethnic groups. The GC system was analyzed in Curiaú and Pacoval, two remnant Quilombo populations (African‐derived populations) from the Brazilian Amazon. There was no significant statistical difference in allelic frequencies between the two populations or between them and three other African‐derived Brazilian populations (Mimbó, Sítio Velho, and Gaucinha in Northeastern Brazil). These populations share similarities among themselves and with African populations (high frequencies of GC*1F and lower frequencies of GC*1S), which may reflect the influence of a high level of African contribution to their formation, but there is a clear difference between them and Europeans and South American Indians. It is suggested that the GC system is a useful marker for studying relationships between single populations and major ethnic groups, but does not discriminate between populations which share the same parental stock.

Presence of the cfxA gene in Bacteroides distasonis

In this study we investigated the presence of the cfxA gene (encoding a class A beta-lactamase) in 73 strains of the Bacteroides fragilis group belonging to the species B. distasonis (34), B. vulgatus (14), B. thetaiotaomicron (8), B. merdae (6), B. caccae (9) and B. ovatus (2) isolated from human intestinal microflora of healthy children and adults. Employing specific primers to the cfxA gene, a 312-bp amplified fragment was obtained in 2 strains of B. vulgatus and 9 strains, the majority from children, of B. distasonis. The expression of this enzyme was analysed by determining the MICs to cefoxitin and cefotaxime and values varied from 2 to >256 microg/ml of both cefoxitin and cefotaxime. Sequence analysis of the amplicons corresponding to the cfxA gene from B. distasonis and B. vulgatus revealed identical sequences between these isolates and high similarity with other beta-lactamase genes of anaerobes such as cfxA of B. vulgatus (99%) and cfxA2 of Prevotella intermedia (99%), both sequences of which deposited in Genbank under accession numbers U38243 and AF118110, respectively. However, a fragment obtained from a B. distasonis strain (EC17-4) showed a unique RFLP profile and 87% nucleotide similarity with cfxA and cfxA2 genes. These results seem to suggest a dissemination of these resistance determinants among Bacteroides species.     

Cytogenetic analysis of 100 consecutive newly diagnosed cases of acute lymphoblastic leukemia in Rio de Janeiro

We report the cytogenetic analysis of newly diagnosed Brazilian children with acute lymphocytic leukemia (ALL). We investigated 100 ALL cases from four different institutions in Rio de Janeiro. The frequency of chromosomal abnormalities was 92.3%. The karyotype profile and recurrent abnormalities found in this study do not differ essentially from those described by other groups. Although the Brazilian population is usually the product of different ethnic groups, our results show that the frequency of each recurrent abnormality is similar to that found in populations without our degree of diverse ethnic composition. Hence, our results suggest that childhood ALL in Brazil has the same biological features as that in developed countries, supporting the use of similar treatment protocols. We can therefore expect to reach the same survival rates in the coming years, depending possibly on the efficacy of the support therapy and extent of social assistance.     

Th1 cell development induced by cysteine proteinases A and B in localized cutaneous leishmaniasis due to Leishmania guyanensis

The cysteine proteinases CPA and CPB from Leishmania major induced Th1 responses in patients with leishmaniasis due to Leishmania guyanensis. Furthermore, cysteine proteinases induced neither interleukin 4 (IL-4) nor IL-13 and low levels of IL-10 in controls and patients. The results suggest that CPs would be quite good candidates for a vaccine against different Leishmania species.
