Most of the published works so far have aimed at finding genes associated with multiple sclerosis (MS) susceptibility. Very few studies have attempted to correlate disease features with DNA variants. In a well-characterized sample (651 patients) representative of multiple sclerosis natural history, we engaged a comprehensive study of the role of human leukocyte antigen (HLA) in the course of the disease. We investigated the role of HLA-DRB1*15 allele in samples stratified according to severity evaluated by the Multiple Sclerosis Severity Score (MSSS), time to reach EDSS 6.0 and disease type. We found that HLA-DRB1*15 genotype does not influence MS severity even among patients presenting with a given type of the disease. However, we show for the first time that HLA-DRB1*15 allele modulates the course of MS for relapsing–remitting (RR) onset patients likely by precipitating the secondary progressive (SP) phase.Genes and Immunity (2008) 9, 570–574; doi:10.1038/gene.2008.52; published online 10 July 2008 [ABSTRACT FROM AUTHOR]

Twenty five patients with peripheral neuropathy at different stages of human immunodeficiency virus (HIV) infection are reported. Cerebrospinal fluid (CSF) findings were available in 17 cases, electrophysiology in all and a neuromuscular biopsy in 11. Of six otherwise asymptomatic HIV+ patients, five had chronic inflammatory demyelinating polyneuropathy (CIDP) and one acute inflammatory demyelinating polyneuropathy (AIDP). CSF showed pleocytosis in all cases. Infiltration of the endoneurium and/or the epineurium by mononuclear cells was seen in biopsies from three cases. These six patients recovered either spontaneously, or with corticosteroids or plasmaphereses. Of five patients with AIDS related complex (ARC), three had distal predominantly sensory peripheral neuropathy (DSPN), one CIDP and one mixed neuropathy. Of 14 patients with AIDS, one had mononeuropathy multiplex and 13 painful DSPN. Electrophysiological studies were consistent with an axonopathy. Nerve biopsies in six cases showed axonal changes but surprisingly associated with marked segmental demyelination in two cases. Cell infiltration was present in nerve samples in two cases. Five patients died within six months after the onset of the neuropathy. [ABSTRACT FROM AUTHOR]

To measure the prevalence and intensity of pain in hospitalized patients and to assess the quality of pain management, an exhaustive cross-sectional study was conducted in every department in a university hospital. Patients hospitalized for 24 hours or more completed an anonymous self-report questionnaire. Among the 1,475 inpatients, 998 completed the questionnaire. During the 24-hour period prior to our survey, 55% experienced pain. On 100 mm pain intensity measures, the median maximum pain experienced in the 24 preceding hours was 60 mm and the median pain intensity at the time of the survey was 30 mm. Although pain measured at the time of survey disappeared in only 16% of patients, 79% were satisfied with pain management. Despite a high satisfaction level, the prevalence and intensity of pain were very high. This study provided baseline data on pain in a French hospital and led to the implementation of a program for improving pain management. [ABSTRACT FROM AUTHOR]

Background: The oral status of people living in precarious conditions is problematic. Although the public universal health insurance should allow better access to care, access to dental care remains a critical issue. The analysis of the patient population of a hospital dental consultation (Groupe Pitié-Salpêtrière, Paris) seemed relevant to evaluate the needs of care and the means to provide it. The principal objectives are: to estimate dental health and needs of this population, to describe their sociodemographic characteristics and to compare them with patients living in common social conditions., Methods: A cross sectional study was conducted from February to June 2003. A medical questionnaire and a dental file record were used. All outpatients coming to the dental consultation, in need of conservative or prosthetic treatment, were included. We analysed the risk factors associated with poor dental health., Results: Three hundred and thirty three questionnaires were analysed: two third were men, 45% were foreigners. More than half of them benefited from a special social health insurance for disadvantaged people or didn't have any health insurance. The comparative analysis of this precarious group vs regular insured people showed significant differences for sociodemographic and oral characteristics. Namely, in the precarious group, a poor dental status was generally observed: more cavities (3.6 versus 2), more absent teeth not replaced (6.8 versus 3.5) and less treated teeth (1.9 versus 3.9)--p < 0.0001. Multivariate analysis showed that main risk factors of poor dental status were to be aged and to be a foreigner., Conclusion: This study stresses the importance of the dental care needs in a context of poor insurance refunding for the costs of dental treatments and the lack of structures able to provide dental care for patients living in difficult social condition. These findings question the organization of the dental care system in France.
