HUGO Gene Nomenclature Committee (HGNC) recommendations for the designation of gene fusions.

Gene fusions have been discussed in the scientific literature since they were first detected in cancer cells in the early 1980s. There is currently no standardized way to denote the genes involved in fusions, but in the majority of publications the gene symbols in question are listed either separated by a hyphen (-) or by a forward slash (/). Both types of designation suffer from important shortcomings.

[Aortitis after G-CSF injections].

Introduction: Aortitis consists in aortic wall inflammation from infectious or non infectious cause. It may lead to aortic aneurysm with a risk of rupture, which is life-threatening and may justify surgical procedures. The cause of the aortitis is sometimes obscure.

[Cytogenetics, cytogenomics and cancer: 2004 update].

Cytogenetics has clearly established the key role chromosomal rearrangements play in neoplastic initiation and progression. Investigation methods have evolved considerably from banding analysis of chromosome morphology to fluorescence in situ hybridization (FISH) and now to comparative genomic hybridization (CGH) on chromosomes or micro-array analysis of DNA. In addition to its contributions to the description, prognosis and understanding of oncogenesis and tumor progression, cytogenomics provides the information required for the rational use of new targeted therapies among which Imatimib is the most achieved example.

Multiple atherosclerotic plaque rupture in acute coronary syndrome: a three-vessel intravascular ultrasound study.

Background: To test the hypothesis of general atherosclerotic plaque destabilization during acute coronary syndrome (ACS), the present study sought to analyze the 3 coronary arteries by systematic intravascular ultrasound scan (IVUS).

Methods And Results: Seventy-two arteries were explored in 24 patients referred for percutaneous coronary intervention after a first ACS with troponin I elevation. Fifty plaque ruptures (mean, 2.

[Multiple ruptures of atherosclerotic plaques in acute coronary syndrome. Endocoronary ultrasonography study of three arteries].

The aim of this study was to assess the three coronary arteries systematically by endocoronary ultrasonography in patients with unstable angina to check the hypothesis of global destabilisation of atherosclerotic plaques in acute coronary syndromes (ACS). Sixty two coronary arteries were examined (2.6 per patient).

[From cytogenetics to cytogenomics of bladder cancers].

Bladder cancers are classified as: transitional cell carcinoma (TCC), the most frequent in Europe/USA, squamous cell carcinoma (SCC), more frequent in the Middle East and in Africa, adenocarcinoma and small cell carcinoma, rare. TCC exhibit pseudo diploid karyotypes with only a few anomalies in early stages, evolving towards pseudo-tetraploides complexes karyotypes. Partial or complete monosomy 9 (-9) is an early event, found in half cases.

[Subacute infectious endocarditis due to the agent of cat scratch fever: Bartonella henselae].

The diagnosis of severe mitral stenosis with left atrial thrombus was rectified at valvular replacement in a 48-year old immuno-competent man who was a cat owner. The mass in the left atrium was, in fact, a large endocarditic vegetation. Pre- and postoperative blood cultures were negative as was culture of the excised mitral valve.

[Communication between the left ventricle and the right atrium in infectious endocarditis. Diagnosis using Doppler-echocardiography].

The diagnosis of a communication between the left ventricle and right atrium was made by transthoracic and transoesophageal echocardiography in a 67 year old man with a recurrence of a methicillin-resistant staphylococcus aureus infectious endocarditis complicating aortic valve replacement with a bioprosthesis seven weeks previously. This diagnosis was confirmed at surgery; the left ventricular-right atrial communication was closed by suturing its edges and a new aortic valve prosthesis was implanted. Unfortunately, the patient died 4 months later of myocardial dysfunction although the infectious endocarditis seemed to have been sterilised by antibiotic therapy.

The naevoid basal-cell carcinoma syndrome (Gorlin syndrome) is a chromosomal instability syndrome.

The Gorlin syndrome, or naevoid basal-cell carcinoma syndrome (NBCS) is an autosomal dominant cancer prone disease (at risk of multiple basal cell carcinomas, and other malignant or benign proliferations). We have previously reported data from peripheral blood lymphocytes of patients with this condition, showing a significant level of spontaneous chromatid and chromosome rearrangements and an overall lengthening of the cell cycle. In this paper, we confirm this disease to be a chromosome instability syndrome from studies on fibroblasts of 5 patients.

[Myocardial infarction in the elderly. Comparison between 2 groups of patients over 75 and under 65 years of age].

To define the clinical characteristics, prognosis and treatment of myocardial infarction (MI) in the elderly, we retrospectively compared the files of 101 patients aged > or = 75 years (mean: 82 +/- 4 years) and of 120 others aged < or = 65 years (mean: 55 +/- 4.7 years). The figures corresponding to younger patients are presented in brackets.

[Value of mass dosage of the MB isoenzyme of creatinine phosphokinase in the diagnosis of recent myocardial infarction].

In 391 patients admitted 3.7 hours (h) (median) after experiencing infarct-like pain, kinetic monitoring of CK-MB "mass" (threshold: 7 micrograms/l), myoglobin (threshold: 90 micrograms/l) and total CK (threshold: 290 micrograms/l) was carried out at the time of admission and after 1.5, 3, 6, 9, 12, 24 and 48 h.

[Ilio-femoral vein thrombosis treated with tissue plasminogen activator in a pregnant woman].

A 27-year-old woman, after 31 weeks of amenorrhoea during her second pregnancy, developed a left external iliac and femoral deep vein thrombosis, confirmed by venous ultrasonography and magnetic resonance imaging. The infusion of tissue plasminogen activator (rt-PA: 1.2 mg/kg, i.

Down syndrome with partial duplication and del (21) syndrome: study protocol and call for collaboration. Study I: Clinical assessment.

We report on the clinical and cytogenetic assessment of five cases of Down syndrome phenotype with either a partial duplication of chromosome 21 or a normal karyotype, and we quote a case of del (21q) syndrome. Down syndromes with a partial duplication of chromosome 21 (as well as cases of del (21q), which are partly the phenotypic countertype of trisomy 21) are of paramount importance in the understanding of genes involved in the phenotype of Down syndrome. The goal is to find the relevant genes implicated in the main traits of Down syndrome (i.
