The prevalence of arthritis is high, with osteoarthritis (OA) being one of the most frequent disorders in the population. In England and Wales, between 1.3 and 1.75 million people have OA and a further 0.25 0.5 million have rheumatoid arthritis (RA), while in France some 6 million new diagnoses of OA Lire made each year. In 1997, similar to16%, of the US population had some form of arthritis. This prevalence is expected to increase in the coining years, as arthritis more often affects the elderly, a proportion of the population that is increasing. The economic burden of such musculoskeletal diseases is also high, accounting for up to 1-2.5%, of the gross national product of western nations. This burden comprises both the direct costs of medical interventions and indirect costs, such as premature mortality and chronic and short-term disability. The impact of arthritis on quality of life is of particular importance. Musculoskeletal disorders are associated with some of the poorest quality-of-life issues, particularly in terms of bodily pain (mean score from the MOS 36-item Short Form Health Survey of 52.1) and physical functioning (49.9), where quality of life is lower than that for gastrointestinal conditions (bodily pain 52.9, physical functioning 55.4), chronic respiratory diseases (72.7, 65.4) and cardiovascular conditions (64.7, 59.3).

Objective Epstein–Barr virus (EBV) has been linked to gastric carcinoma (GC) with worldwide geographical variations of prevalence ranging from 1 to 18% of cases. Investigations carried out in north Africa have shown that some EBV-associated types of cancers are common in this area. This study was taken to determine the prevalence of EBV-associated GC in Tunisia. Methods Ninety-six nonselected GC cases (male/female ratio 1.7/1, mean age 60.9 years, range: 20–88 years) were evaluated for the presence of EBV by polymerase chain reaction as well as by in-situ hybridization for EBVencoded small RNAs (EBERs) and immunohistochemistry for LMP-1 and EBNA-2 expression. Results EBV was detected by polymerase chain reaction in 36% of cases, whereas EBERs were detected in the tumor cells in only four cases (4.1%). Immunohistochemistry for LMP-1 and EBNA-2 was negative in all cases. The mean age for patients harboring EBERs-positive GC was 55.7 years (range: 52–59 years). All EBERs-positive GC cases were males of advanced clinical stage (pT3–pT4). According to Lauren’s classification, two cases were of diffuse histological type and two cases were of intestinal type. In three cases, the tumors have a proximal location and in the remaining case the tumor arises in the antrum. All EBV strains detected from EBV-associated GC were exclusively of type A and D, prototype F, and XhoI-maintained variant. Conclusion We conclude that the prevalence of EBV-associated GC in Tunisia is low (4.1%), suggesting that this virus is not an important etiological factor in GC arising in north African populations. The clinicopathological profile of EBV-associated GC in Tunisia did not differ markedly from that found elsewhere. [less ▲]

The involvement of a retrovirus homologous to the mouse mammary tumor virus (MMTV) in the pathogenesis of human breast cancer (BC) has long been assumed, but has never been proven. Previous studies have reported the detection of MMTV-like env sequences in variable proportions that did not exceed 40% of BC cases in several countries. However, these viral sequences have been found in higher proportion (74%) in Tunisian diagnosed with BC during the seventies. This study is an attempt to evaluate the current prevalence of MMTV-like env gene in BC in Tunisian women. We used semi-nested PCR that amplify a 190-bp MMTV-like env sequence, followed by direct sequencing to screen a series of 122 cases of BC randomly selected. The findings were correlated to clinicopathological data and immunohistochemical expression status of progesterone and oestrogen receptors, HER2, and P53. Specific MMTV-like env sequences were found in 17 (13.9%) cases of breast carcinomas, whereas the same sequences were not detected in matched normal breast tissues. The presence of the viral sequences correlates inversely with progesterone receptor expression (6.8% versus 20.3%; P = 0.03) and HER2 overexpression (3.1% versus 17.7%; P = 0.04). This present study confirms the presence of MMTV-like env sequences in BC in Tunisian women but describes an important decrease in the prevalence of the viral sequences compared with pervious studies. This reduction may be due to some changes in the virological characteristics or exposure to the virus. [less ▲]

In order to determine the prevalence and to characterize the carriage of Microsporum canis in cats, different mycological examinations (including a culture obtained by hair brushing and Wood's light examination) were performed on 632 animals of different origins. Group 1 comprised 467 healthy pet cats belonging to veterinary students. In this group, prevalence of carriage was 2.1%: eight cats were asymptomatic transient carriers and one cat was an asymptomatic infected animal presenting discrete Wood's-positive lesions disseminated on the whole body that were visible after sedation and clipping. The carriage prevalence was higher (15.7%) in group 2 comprising 134 European cats destroyed in a pound and kept together. In two additional groups of cats, it was shown that an infected cat was responsible for the dissemination of fungal material into its environment including the other in-contact animals. When the active source of fungus was removed, the dissemination stopped, resulting in a decrease in the amount of infective material recovered from both the animal carriers and the environmental surfaces. This was also observed in two experimental groups of guinea pigs. No association between feline immunodeficiency virus infection and the M. canis carriage was observed in a retrospective case-control study performed on group 2. None of these cats was feline leukaemia virus positive. [less ▲]

Objective: Since the availability of recombinant human growth hormone (rhGH) all children with growth hormone deficiency (GHD) living in Belgium are offered rhGH treatment after approval by a peer-review board. In this study, we evaluated the prevalence and demographic features of childhood GHD in Belgium during the period 1986-2001 and we compared them with the data from other countries. Methods: Diagnostic, demographic and baseline auxological data of 714 children diagnosed as having GHD between 1986 and 2001 were retrieved from the database of the Belgian Study Group for Paediatric Endocrinology. Results: The prevalence of GHD in Belgium was estimated to be 1/5600. The origin of GHD was idiopathic (idGHD) in 41% of the patients, congenital (congGHD) in 20% and acquired (acqGHD) in 35%. During the first 4 years (1986-1989) more patients were classified as idGHD; thereafter the distribution between the three aetiology groups did not change. In all groups, boys outnumbered girls but this preponderance was especially pronounced in congGHD patients (male:female = 4:1) with a central malformation that associates an anterior pituitary hypoplasia, a missing, fine or normal pituitary stalk and an ectopic posterior pituitary. Thirteen percent of the patients with idGHD, 50% with congGHD and 52% with acqGHD had multiple pituitary deficiencies. Patients with congGHD were the youngest (mean+/-S.D. age: 6.5+/-4.7 years) and were the shortest (-3.0+/-1.3 standard deviation score (SDS)) at the start of rhGH treatment. There was no time trend over the studied period for age and height at onset of GH therapy. Conclusion: In Belgium, the prevalence of childhood GHD can be estimated as 1/5600 which is comparable to other recent surveys. The yearly number of new patients for the different aetiologies and the auxological parameters have remained relatively constant over the last 16 years. [less ▲]

This study is the first prospective study to assess the prevalence, epidemiology, and risk factors of HIV-1 drug resistance in newly diagnosed HIV-infected patients in Belgium. In January 2003 it was initiated as part of the pan-European SPREAD program, and continued thereafter for four inclusion rounds until December 2006. Epidemiological, clinical, and behavioral data were collected using a standardized questionnaire and genotypic resistance testing was done on a sample taken within 6 months of diagnosis. Two hundred and eighty-five patients were included. The overall prevalence of transmitted HIV-1 drug resistance in Belgium was 9.5% (27/285, 95% CI: 6.6-13.4). Being infected in Belgium, which largely coincided with harboring a subtype B virus, was found to be significantly associated with transmission of drug resistance. The relatively high rate of baseline resistance might jeopardize the success of first line treatment as more than 1 out of 10 (30/285, 10.5%) viruses did not score as fully susceptible to one of the recommended first-line regimens, i.e., zidovudine, lamivudine, and efavirenz. Our results support the implementation of genotypic resistance testing as a standard of care in all treatment-naive patients in Belgium. [less ▲]

Background and aims: To assess the prevalence and impact of osteoarthritis (OA) and osteoporosis (OP) on health-related quality of life (HRQOL) among active subjects employed in the public workforce in Belgium. Methods: A cohort of 3440 subjects employed by the Liege City Council was prospectively followed for 6 months. The employees were asked to fill in a monthly log in a health record book, of data regarding their healthcare consumption due to OA and OP. HRQOL was assessed using the Medical Outcomes Study Short Form-36 (SF-36). Results: 1811 subjects (52.6%) filled in at least one questionnaire. The mean duration of follow-up was 3.46 months. The self-reported prevalence of OA and OP at entry to the study were respectively 34.1% and 5.3%. 3.6% of subjects reported suffering from both OA and OP. Subjects with OA and both OA and OP had significantly lower scores on all SF-36 dimensions compared with normal subjects, reflecting a worse HRQOL. The OP group had significantly lower mean scores for physical functioning and pain compared with controls. Subjects with both OA and OP had significantly lower values for physical functioning, physical role and pain when compared with the OA and OP groups. Conclusions: The results of this survey of a large sample of active subjects show that self-reported osteoarthritis and osteoporosis are common in the workplace. Both diseases have a major impact on health-related quality of life compared with that of people without self-reported musculoskeletal diseases. [less ▲]
