Abstract
OBJECTIVE To identify the risk factors for ectopic pregnancy (EP) in women using an intrauterine device (IUD). DESIGN Case-control study. SETTING Auvergne region (France). PATIENT(S) Women using an IUD and suffering EP (243 cases) or having an intrauterine pregnancy (140 controls). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Sociodemographic characteristics, smoking, medical history, and medicines taken before the pregnancy. Type of IUD, duration of use, position and visibility of the thread at diagnosis, and presence of abnormal clinical signs. RESULT(S) Seven factors were associated with an increase in the risk of EP: histories of spontaneous abortion, IUD use, and tubal damage; progesterone IUD at the time of conception; insertion of an IUD during the month following a previous pregnancy; duration of use of the IUD in place at the time of conception; and pelvic pain resulting in medical consultation after the insertion of the IUD. Conversely, five factors were associated with a decrease in the risk of EP: history of treated low genital tract infection; history of contraception using the progestagen pill; use of paracetamol or aspirin before the pregnancy; and displacement of the IUD. CONCLUSION(S) This study suggests that the IUD itself may have an etiological role in EP.

Abstract
This multicentre retrospective study describes the clinical features and prognostic significance of Varicella-zoster virus (VZV)-associated neurological complications. The study was performed in patients with human immunodeficiency virus (HIV) infection, hospitalized for VZV neurological complications, confirmed in every case by positive VZV polymerase chain reaction (PCR) in cerebrospinal fluid (CSF). Between 1990 and 1995, 34 HIV-infected patients were included in the study. At diagnosis, 59% had AIDS, with a median CD4 count of 11 x 10(9)/l. A past history of zoster was noted in 35% of cases. A concomitant herpes zoster rash and/or acute retinal necrosis were noted in 71% and 12% of patients, respectively. The predominant neurological manifestations were encephalitis (13), myelitis (8), radiculitis (7) and meningitis (6). The mean CSF white blood cell count was 126/mm3 and the mean CSF protein concentration was 2.3 g/l. Interferon-alpha level was increased in 36% of patients. VZV was isolated from CSF cultures in 2/6 cases. Magnetic resonance imaging was abnormal, demonstrating encephalitis lesions. After intravenous antiviral therapy, complete recovery was obtained in 18 cases (53%), serious sequelae were observed in 10 cases (29%) and 6 patients died (18%). Severe symptoms and a low CD4 cell count appeared to be associated with death or sequelae. In conclusion, VZV should be considered as a possible cause of encephalitis, myelitis, radiculitis or meningitis in HIV-infected patients, especially in patients with a history of or concomitant herpes zoster or acute retinal necrosis. VZV-PCR in the CSF may allow rapid diagnosis and early specific antiviral treatment.

Abstract
Conventional radiotherapy is usually indicated in acromegaly when surgery fails to normalize GH secretion. However, the benefits of radiotherapy are delayed. This has raised questions about the potency of this treatment for reaching the safe GH level of 2.5 microg/L and for normalizing insulin-like growth factor I (IGF-I) levels, both of which are currently recommended as the therapeutic goal. To evaluate the long-term hormonal and metabolic effects of radiotherapy in acromegaly, a retrospective analysis was undertaken studying 128 patients followed for 11.5+/-8.5 yr (mean +/- SD) in a single center. The preradiation GH levels decreased as a function of time to 50% at 2 yr, 20% at 5 yr, and 10% at 10 yr. Basal GH levels below 2.5 microg/L were obtained in 7% of the patients at 2 yr, 35% at 5 yr, 53% at 10 yr, and 66% at 15 yr. A basal GH level below 2.5 microg/L was associated with suppression of GH below 2 microg/L during an oral glucose tolerance test and normalization of IGF-I levels in 9 of 10 patients. Preradiation GH levels was the sole factor that could predict the delay in GH fall to below 2.5 microg/L (P = 0.008). At the last follow-up, IGF-I levels were normalized in 79% of the patients (37 of 47; mean follow-up, 15.0+/-11.3 yr). In the 32 patients presenting with diabetes mellitus, improvement of glucose tolerance was associated with lower GH levels after treatment (35+/-78 microg/L in the group of 13 patients still presenting diabetes; 9+/-12 microg/L in the group of 4 patients with glucose intolerance; 5+/-8 microg/L in the 14 patients with normal glucose tolerance; P = 0.04). Ten years after termination of radiotherapy gonadotroph, thyreotroph and corticotroph deficiencies were observed in 80%, 78%, and 82% of the patients, respectively. In conclusion, conventional radiotherapy can reduce GH levels below the optimal level of 2.5 microg/L and normalize IGF-I levels in acromegaly. However, the incidence of late hypopituitarism is high, and the delay to obtain this safe GH secretory status can be long, depending on the preradiation GH level. These parameters should be considered when adjuvant therapy is needed after surgery.

Abstract
OBJECTIVE To determine the cumulative incidence and the point prevalence of atopy in patients with rheumatoid arthritis (RA). PATIENTS AND METHODS A standardized questionnaire was sent to 300 RA patients. Questions concerned previous or present characteristics of atopy (hay fever, asthma and constitutive eczema) and RA. RA patients were matched with genetically unrelated controls (sister- or brother-in-law, neighbour or friend). The same questionnaire (except for questions about RA) was sent to the control subjects. In cases of atopy, patients, controls and the treating physicians were contacted by a physician to check the validity of the responses. RESULTS Paired responses were obtained in 173 cases. Information about atopy was obtained for 69 other RA patients. The characteristics of RA were similar for patients who responded and those who did not respond. The frequency of atopy was significantly lower in RA patients than in controls, both for cumulative incidence (RA 7.5%, controls 18.8%; P: < 0.01) and point prevalence (RA 3.5%, controls 16.2%; P: < 0.0001). The clinical manifestations of atopy stopped before the onset of RA in eight of the 17 RA patients with an allergic condition, and there was no subsequent relapse. No effect of RA treatment could account for the remission of atopy. CONCLUSION These data support the concept that atopy protects against the future development of RA and that the two diseases could counterbalance one another.

Abstract
BACKGROUND AND OBJECTIVES Posttransfusion hepatitis still occurs at an incidence of about 1 in 118,000 for HBV and 1 in 220,000 for HCV. This collaborative study aimed to determine the prevalence of a novel flavivirus, GBV-C/HGV, even though its role in transfusion-associated hepatitis is uncertain. MATERIALS AND METHODS GBV-C/HGV RNA was detected by PCR using either the Boehringer detection kit or by primers previously described. HGV antibodies were detected by a serological assay from Boehringer. RESULTS The observed GBV-C/HGV RNA frequency was 3.4%. HGV antibodies occurred in 9.5% of donors. CONCLUSION In our study, 12. 9% of the donors had been in contact with the GBV-C/HGV virus.

Abstract
BACKGROUND AND OBJECTIVES An unusual serological pattern of HIV-1 seroconversion in a blood donor is described. The seroconversion panel was used to investigate the sensitivity of existing screening assays. MATERIALS AND METHODS A volunteer blood donor who had given blood 79 times was diagnosed anti-HIV-1-antibody-positive. The heteroduplex mobility assay identified a subtype B HIV-1 strain. The frozen plasmas from the last four blood donations had been kept at -30 degrees C. They were thawed and aliquoted for subsequent testing. RESULTS The last two blood donations contained HIV-1 RNA, 2,800 copies/ml (October 26) and 170 copies/ml (November 23). Weak anti-p24 antibodies were detected by Western blot in the October 26 sample, and a clear p24 reactivity along with a faint gp160 reactivity was observed on November 23. HIV p24 antigen was undetectable in both samples. Out of 13 screening assays, only 6 gave positive results on the November sample and 7 negative results which were obtained by 1 competitive enzyme immunoassay (EIA) and 6 of the 9 sandwich EIAs. CONCLUSION Most sandwich EIAs gave prolonged false-negative results in the present case. p24 antigen testing was negative and would not have reduced the risk of HIV transmission.

Abstract
OBJECTIVE To describe the long-term outcome and determine predictors of severity among patients with oligoarticular-onset juvenile idiopathic arthritis (JIA). METHODS In a longitudinal study, 207 patients with oligoarticular-onset JIA who were referred between 1988 and 1998 were evaluated. At disease onset, selected clinical and laboratory data were collected as independent variables. A polyarticular disease course, joint erosion, uveitis, and remission were assessed as dependent variables. Longitudinal analyses were performed with the Kaplan-Meier method, and multivariate analysis with the Cox model. RESULTS After 6 years of followup, the probability of a polyarticular course of disease was 50%, joint erosion was 35%, uveitis was 30%, and remission was 23% in these patients. Joint erosion was strongly associated with a polyarticular course. A high erythrocyte sedimentation rate (ESR) as well as involvement of more than 1 joint or involvement of an upper limb at disease onset were predictors of disease extension. A high ESR was also a strong predictor of a destructive course, and a family history of psoriasis was predictive of uveitis occurrence. No predictive factor for remission could be identified. CONCLUSION Oligoarticular-onset JIA is a severe disease with frequent complications. Factors predictive of severity in oligoarticular-onset JIA were identified. This could allow early identification of high-risk patient subgroups, warranting a more aggressive therapeutic approach.

Abstract
OBJECTIVE To assess whether subsequent pregnancies increase the risk of recurrent stroke and whether the occurrence of an ischemic stroke affects reproductive history. METHODS The authors identified 489 consecutive women aged 15 to 40 years with a first-ever arterial ischemic stroke or cerebral venous thrombosis from the record system of nine French neurologic centers. Information on stroke recurrence and reproductive history was obtained by means of chart review, written questionnaire, and telephone interview. RESULTS Data were analyzed from 441 women (373 with arterial ischemic stroke and 68 with cerebral venous thrombosis). During a mean follow-up of 5 years, 13 arterial recurrent ischemic strokes occurred. There were no cases of recurrent cerebral venous thrombosis. The overall risk of recurrence was 1% within 1 year and 2.3% within 5 years. The risk of recurrence was significantly higher in patients with stroke of definite cause. Eleven recurrent strokes occurred outside pregnancy (absolute risk of recurrence = 0.5%; 95% CI 0.3, 0.95) and two during pregnancy or the puerperium (absolute risk of recurrence = 1. 8%; 95% CI 0.5, 7.5). The relative risk of recurrence was significantly higher during the postpartum period (risk ratio = 9.7; 95% CI 1.2, 78.9) than during pregnancy (risk ratio = 2.2; 95% CI 0. 3, 17.5) itself. The outcome of the 187 subsequent pregnancies was similar to that expected from the general population. Thirty-four percent of women indicated that they would have desired more pregnancies after their initial stroke. The main reasons for not considering pregnancy were concern of a recurrent stroke, medical advice against pregnancy, and residual handicap. CONCLUSION Young women with a history of ischemic stroke have a low risk of recurrence during subsequent pregnancies. The postpartum period, not the pregnancy itself, is associated with an increased risk of recurrent stroke. The outcome of pregnancies in these women appears to be similar to that expected in the general population. A previous ischemic stroke is not a contraindication to a subsequent pregnancy.

Abstract
OBJECTIVE The study was designed to evaluate the clinical, endocrinological and radiological parameters used to investigate adrenal incidentalomas and select patients for surgery. DESIGN AND METHODS An analysis of 88 consecutive patients with adrenal incidentaloma selected for surgery and investigated in a single clinical center was performed. RESULTS Mean (+/-s.d.) age of the patients was 53+/-14 years. Fourteen (16%) of the adrenal incidentalomas were malignant tumors (2 adrenocortical carcinomas, 3 metastases, 4 adenocarcinomas, 4 sarcomas and 1 mesenchymoma), 10 (11%) were pheochromocytomas, 32 (36%) were non-secretory benign adrenal adenomas and the remaining were benign adrenal (n = 8; 9%) or extra-adrenal (n = 24; 27%) masses. Endocrinological investigations revealed 1 Conn adenoma, 4 tumors responsible for Cushing's syndrome or silent hypercortisolism and 1 androgen secreting tumor. Abnormalities of endocrine evaluations were observed in the 2 malignant adrenocortical carcinomas. Elevated 24-h urinary metanephrine levels were observed in the 9 pheochromocytomas tested. Complications of surgery occurred in 14% of the cases. Regardless of the endocrine status, parameters associated with malignant tumors were: older age (mean age of patients harboring malignant tumors vs patients with benign incidentalomas: 62+/-17 years vs 52+/-13 years, P = 0.005), weight loss (39% vs 7%, P = 0. 005), and mass diameter greater than 60mm (69% vs 15%, P < 0.001). By multiple logistic regression analysis malignant tumors were associated with increased age, diameter greater than 60mm and bilateral masses. CONCLUSION This study points to a high rate of pheochromocytomas and malignant tumors in patients selected for surgery. This high rate differs from some previous reports and might be explained by the criteria used to select patients for surgery. Among these two groups of tumors, careful systematic endocrinological investigations allow the detection of altered secretion in the vast majority - if not all - malignant tumors of adrenal origin and pheochromocytomas. Only 5% of the incidentalomas below 30 mm selected for surgery in this study were malignant, in keeping with the use of this criteria as an important parameter to select patients with normal hormonal investigations for careful follow-up.

Abstract
OBJECTIVE Health care has variable features, specific determinants, and consequences on people's health that should be investigated in a population perspective. We present a population-based analytical approach to assessing patterns, determinants, and outcomes of health care. METHODS The approach uses standard epidemiological methods for sample selection and analysis, as well as statistical methods concerning model fitting and validation strategy. It also uses psychometric methods allowing pattern identification: factor analysis, cluster analysis, and polytomous logistic regression to investigate the factors associated with identified patterns of care. The approach is illustrated with an application to ectopic pregnancy (EP). RESULTS EP diagnostic and therapeutic procedures appeared to be closely related, suggesting 3 differentiated patterns of care. Predictors of these patterns were not only the clinical features and the woman's prior gynecological history but also center characteristics and location. These patterns were found to influence immediate and middle-term outcomes and risk of recurrence of EP. CONCLUSIONS We illustrate the feasibility and profitability of a population-based analytical approach to identify patterns, determinants, and consequences of care. This approach could be used to analyze other pathological conditions and health care systems.

Abstract
BACKGROUND The objective of this collaborative study was to learn the proportion of HCV RNA-positive samples obtained from a population of donors with isolated anti-HCV reactivities by third-generation RIBA (RIBA-3) (indeterminate results). STUDY DESIGN AND METHODS During a 2-year period, 11 blood transfusion centers kept all samples with indeterminate RIBA-3 results to test them by PCR, using both local and commercial techniques. RESULTS Of the 758 RIBA-3 indeterminate samples, 10 (1.3%) were positive for HCV RNA: 3. 3 percent (6/180) and 1.3 percent (4/317) of samples with anti-core or anti-NS3 reactivity, respectively, and none of the 52 and 209 samples with anti-NS4 or anti-NS5 reactivity, respectively. HCV RNA-positive donors with anti-core reactivity were infected with different subtypes (1 with HCV subtype 1b, 1 with 2, 1 with 2a/2c, 2 with 3a, and 1 with 5a), and a follow-up indicated a chronic-carrier state in two of the six donors. Acute hepatitis was diagnosed in three of the four donors with anti-NS3 reactivity alone. Two of these three were IV drug users and were infected with subtype 1a. CONCLUSION HCV RNA-positive donors with indeterminate results in RIBA-3 are extremely rare, but they do exist. They were observed only when either anti-core or anti-NS3 was present. With such a RIBA-3 profile, PCR testing remains necessary to reveal an eventual acute or chronic HCV infection.

Abstract
Despite sustained improvement of donor selection and serologic screening assays, there still remains a small but significant transfusion risk for each of the major viral agents (hepatitis B virus [HBV], hepatitis C virus [HCV], human immunodeficiency virus [HIV] and human T-cell leukemia virus [HTLV]). The risk is due to the failure of the screening tests to detect all the infected blood donations and in particular those which are recently infected in the pre-seroconversion window phase of infection, and the asymptomatic immunosilent chronic carriers who never develop antibodies. Another source of risk relates to variant strains of known viruses that are not detected by the current assays. The last potential risk involves the failure to detect infected blood samples because of inaccurate performances of the test process. In order to reduce this residual risk, the French health authorities requested the progressive introduction of nucleic acid technology (NAT) in blood screening so as to be generalised to all blood centres in the course of year 2000. Multicentric studies are underway to identify the most suitable techniques for the French network.

Abstract
OBJECTIVE To investigate the factors influencing the choice of treatment for ectopic pregnancy and to compare the subsequent fertility rates of radical, conservative-surgical or medical treatments. DESIGN Population-based study of 835 ectopic pregnancies registered between 1992 and 1996. SETTING Auvergne Ectopic Pregnancy Register (France). SAMPLE Four hundred and seventy-six women with tubal ectopic pregnancy who were not using contraception at the time of conception. Subsequent fertility was studied for the 291 women who attempted to conceive again. METHODS Comparison of reproductive outcomes according to ectopic pregnancy treatment. Cumulative fertility curves were calculated by the Kaplan-Meier estimator and compared by log rank test for univariate analysis and by Cox regression to take into account confounding variables. MAIN OUTCOME MEASURE Recurrence and fertility rates after ectopic pregnancy. RESULTS The first treatment given was 'radical' for 178 women (37%), 'conservative-surgical' for 262 (55%), and 'medical' for 35 (8%). The treatment failed in 1% for radical treatment, 5% for conservative-surgical treatment, and 36% for medical treatment. The two-year cumulative rate of recurrence was 27% with no significant difference between treatments. For women with previous infertility factors (in particular diseased contralateral tube), the treatments differed significantly, with the rate of intrauterine pregnancy lower for radical treatment and higher for medical treatment than for conservative-surgical treatment. For women with no infertility factor, there was no significant difference between treatments. CONCLUSIONS These results should be confirmed in a controlled trial. The results of this study provide the elements necessary to plan such a trial.

Abstract
OBJECTIVE Long-term therapeutic success of powerful antiretroviral treatments dependent on patient adherence. This study was conducted to assess the difficulties HIV-infected patients with advanced-stage disease encounter in adhering to antiretroviral treatments with a protease inhibitor. PATIENTS AND METHODS A prospective self-administered questionnaire survey was conducted at our outpatient clinic for 2 months. CD4 counts and HIV viral loads were also determined. RESULTS Seventy-one percent of the study population which included 262 responded to the questionnaire. The survey was made a median 215 days after initiating the antiprotease treatment with indinavir (71% of the cases), ritonavir (13%), saquinavir (6%), or a combination of protease inhibitors (10%). At onset of antiprotease treatment, mean CD4 count was 171+/-150/mm(3) and mean HIV viral load was 75,000 copies/ml. The treatment was considered to be difficult to take by 43% of the patients; 66% stated they had forgotten to take their drugs at least once a month. It was most difficult to take the drugs prescribed for the afternoon. Shifts of 1 hour were observed in 58% of patients. Non-adherence was frequent (1 failure to take drugs per week), observed in 13% of patients. Most often, the patients stated they had forgotten to take their drugs because of occupational or relational difficulties (52%). Non-adherence increased with duration of treatment. The drug most often associated with non-adherence was indinavir (73%). Age and sex did not influence adherence. Mean RNA HIV serum level was lower than at onset of the antiprotease treatment in the most non-adherent patients. At the time of the questionnaire, there was no difference in serum RNA HIV level or in the percentage of patients with an undetectable level between non-adherent and adherent patients. CONCLUSION This survey confirmed difficulties in adherence are frequent and worsen with time. No relationship was found between non-adherence and reduction in viral load, suggesting that a short-term effect of these very active drugs despite lack of perfect adherence. Other factors (pharmacology, sensitivity to antiretroviral drugs.) also play a major role in therapeutic success.

Abstract
PURPOSE OF THE STUDY To compare femoral reconstruction using megaprosthesis versus allograft prosthesis composite. MATERIAL AND METHODS Forty-one consecutive proximal femoral reconstructions with an allograft-prosthesis composite (21 cases) or a megaprosthesis (20 cases) after tumor resection were reviewed in a retrospective study. The following criteria were considered: functional outcome; long term survival; complications. Chi-square test and Wilcox tests were used to compare groups. The medium and long-term survival curves for these reconstructions were made using the Kaplan-Meier standard methods. The failure of prosthesis was defined as revision for mechanical failure (either aseptic loosening or dislocation), for infection or local recurrence. The comparison of the curves was performed using the Log-Rank test. RESULTS Infection (10 p. 100) and instability, in both groups, and loosening, in the megaprosthesis group, were the common causes of failure. There was difference between functional results in the two groups (limping and crutches using was more lower in allograft-prosthesis composite group). Survival analysis showed a 5 and 10-year survival of 77 +/- 12 p. 100 for the patients with composites. Five and ten - year survival were 73 +/- 11 p. 100 and 0 p 100 respectevely for those with megaprostheses. No significant difference was noted between survival of these two groups but a tendancy (p =0.09). Radiological allograft resorption was noted for more than 50 p. 100 of allograft composite prosthesis without modification of functional result or symptomatic loosening. DISCUSSION The functional results seem better in the composite group when compared to the megaprosthesis group. Reconstruction of the abductor mechanism is essential to stabilize the prosthesis and to decrease the limp. When the great trochanter cannot be preserved, we used suture of gluteus medius tendon to tensor of fascia lata, which is re-enforced using a piece of biceps femoris. The dislocation rate was approximately the same in our two groups. Several authors reported a lower dislocation rate with composite reconstructions than massive prosthesis. The rate of infection is similar to other reported series. In our study it has been possible to show a tendancy for superior survival of the composite reconstruction. When the review was later than 5 years the radiological appearance of the graft in our series was often concerning with resorption or fragmentation present in six of the eight cases. This radiological appearance is not as yet responsible for any revision or any change in the functional result however it does remain a worry. CONCLUSION Composite reconstructions probably allow a better functional result when considering proximal reconstruction of the femur. The radiological appearance of these allografts in the long term is however worry some without any evidence so far of worsening functional level or any evidence of prosthetic loosening. It would seem to us that the current level of knowledge would advocate the use of massive allografts together with prosthesis. This does seem still to remain the best choice for proximal femoral reconstruction.

Abstract
The aim of this study was to identify relationships between injecting and sexual risk behaviours and hepatitis C virus (HCV) status knowledge in intravenous drug users (IDUs). It was a cross-sectional survey (March 1994-June 1995) in 10 drug abuse treatment or psychosocial centres in Paris, France. We used a structured questionnaire about sexual, injecting, HIV and HCV antibody testing practices and results during the previous 6 months. Six hundred and twelve sexually active IDUs aged 18 or older who were current injecting drug users were interviewed. Of 592 respondent IDUs, 37% did not report consistent HCV testing and 34% reported being HCV-positive. HCV-positive IDUs were older than HCV-negatives and HCV-unknowns. HCV-unknowns and HCV-positives had a lower educational level than HCV-negatives. After adjusting for demographic characteristics and HIV status, the factors associated with being HCV-unknown were not using condoms (OR: 2.9; 95% CI: 1.9-4.6) as well as clean equipment (OR: 1.8; 95% CI: 1.2-3.0). Not using new equipment was negatively associated with being HCV-unknown (OR: 0.4; 95% CI: 0.2-0.6) and with being HCV-positive (OR: 0.5; 95% CI: 0.3-0.8). Our study suggests that particular sexual and injecting risk-behaviours are associated with not knowing HCV status. As HCV-unknown IDUs are likely to be at the risk of transmitting HCV or acquiring other infections. HCV testing should be encouraged and associated with sexual counselling. Special attention should be paid to disinfecting practices for HCV-positives and use of new injecting equipment should be recommended for HCV-negatives.

Abstract
Fertility after ectopic pregnancy (EP) was investigated in a non-selected population taking into account intrauterine device (IUD) use at the time of the EP. Between January 1992 and June 1996, 647 women listed in the EP register of Auvergne (France) were followed up. The analysis included only the 328 women who were seeking to become pregnant: 23 women using IUD at the time of the index EP (IUD users) and 305 IUD non-users. Among IUD users, there was no recurrence of EP, and the 1 year cumulative rate was 87% [95% confidence interval (CI): 73-100%] for intrauterine pregnancies and 86% (95% CI: 72-100%) for deliveries. Among IUD non-users, the 2 year cumulative rate for recurrence of EP was 28% (95% CI: 17-39%), and the 1 year cumulative rates were 60% (95% CI: 53-66%) for intrauterine pregnancies and 44% (95% CI: 38-56%) for deliveries. The adjusted intrauterine pregnancy rate of IUD users was not significantly different from that of IUD non-users. However, IUD non-users had more miscarriages, so their delivery rate was lower.

Abstract
We conducted a prospective study among 166 multiple sclerosis (MS) patients (103 from an university hospital, 63 from a MS rehabilitation center) to assess the properties of the French version of the Multiple Sclerosis Quality Of Life - 54 items (MS QOL-54) which combines the MOS SF36 together with MS specific items. The SF-36 had been translated into French through the IQOLA project. We translated and adapted the MS specific items with the help of three different teams. The translation into French has an addition of five items, because we kept the MS specific items of an earlier unpublished form. Acceptability is excellent with a response rate over 90p.100. Test-retest reliability is good except for the "role limitation-emotional" scale of the SF-36. Construct validity, based on factor analysis, shows no change in the SF-36 internal consistency and the specific items provided their own information. External validity, tested against both medical (Expanded Disability Status Scale, Kurtzke scale, Mini-Mental-State and disease stage) and rehabilitation (Functional Independence Measure) parameters is excellent. The French MS QOL questionnaire contains 59 items including both the SF-36 and the MS QOL-54 items. This will permit international comparisons of MS patients' care and therapy.

Abstract
OBJECTIVE Procalcitonin concentration increases in bacterial infections but remains low in viral infections and inflammatory diseases. The change is rapid and the molecule is stable making it a potentially useful marker for distinguishing between bacterial and viral infections. PATIENTS AND METHODS Procalcitonin (PCT) was determined with an immunoluminometric assay on plasma collected at admission in 436 infants and children hospitalized for bacterial or viral infection. It was compared with C reactive protein, interleukin-6 and interferon-alpha measured on the same sample. RESULTS PCT was 41.3 +/- 77.4 micrograms/l in children with septicemia or bacterial meningitis (n = 53), 0.39 +/- 0.57 microgram/l in children with viral infection (n = 274) and 3.9 +/- 5.9 micrograms/l in children with a localized bacterial infection who had a negative blood culture (n = 109). PCT was > 1 microgram/l in 126 children with a localized or systemic bacterial infection (sensitivity 78%). PCT was < 1 microgram/l in 258 children with a viral infection (specificity 94%). For differenciation between viral and bacterial infections, CRP value > or = 20 mg/l, IL-6 > 100 pg/ml and interferon-alpha > 0 Ul/ml have 85, 48 and 76% sensitivity and 73, 85 and 92% specificity respectively. CONCLUSIONS In this study, a PCT value of 1 microgram/l or greater had better specificity, sensitivity and predictive value than CRP, IL-6 and interferon-alpha in children for distinguishing between viral and bacterial infections. PCT may be useful in pediatric emergency room for making decision about antibiotic treatments.

Abstract
OBJECTIVE The human placenta normally expresses the pro-opiomelanocortin (POMC) gene. The pattern and secretory kinetics of POMC and/or POMC-derived peptides by the placenta during gestation is still debated. We recently demonstrated that full length POMC was a normal product of the human placenta. The aim of our study was to establish its normal secretory kinetics and to explore its physiological relevance. DESIGN In a prospective, longitudinal study, thirty normal pregnant women had monthly measurements of plasma POMC. In a cross-sectional study of 128 healthy pregnant women, plasma POMC and human chorionic gonadotrophin (hCG) were concomitantly measured to assess their correlation. Finally, POMC levels were assessed in venous and arterial cord blood samples, in amniotic fluid and in retroplacental blood. METHODS Plasma POMC was measured by a specific IRMA in unextracted blood or biological fluid. RESULTS Plasma POMC became detectable by the 8th week of pregnancy and reached its maximum at around the 20th week, remaining stable thereafter. The relationship between POMC and gestation time (weeks) best fitted with a third degree polynomia curve. A significant negative correlation (P=0.01) was observed between plasma levels of POMC and hCG after adjustment for gestation time to take into account the dependence of both hormones on this parameter. POMC was not secreted into the fetal circulation at term, but was present in very high levels in amniotic fluid. The highest levels of POMC were present in the retroplacental blood where the values were 35 times higher than in maternal blood; by comparison, corticotrophin releasing hormone and ACTH values in this compartment were twice or equal to those in the maternal blood. CONCLUSION Placental POMC secretion increases during the first half of pregnancy and reaches a plateau from the 20th week to delivery. The inverse correlation between POMC and hCG plasma levels, and very high POMC levels at the feto-maternal interface suggest a physiological role for this precursor during pregnancy.

Abstract
OBJECTIVE To assess drug prescribing by primary care physicians in France for various types of conditions, and to identify patterns and risk factors for poor prescribing quality. METHODS The orders (n = 23,080) written for patients with five target diseases (acute nasopharyngitis, acute tonsillitis, essential hypertension, osteoarthrosis, and back and periarticular disorders), by primary care physicians (n = 1,049) were extracted from a nationwide prescription database and analyzed according to 17 quantitative indicators of drug prescribing quality constructed on explicit a priori criteria. RESULTS Ineffective drugs were prescribed in 32% to 88% of orders according to the target disease. Six percent to 40% of orders resulted in drug interactions, age problems, and overdosage. A consistent pattern of associations between indicators was found, which suggests that drug prescribing quality is multidimensional and is composed of at least five dimensions: placebo, novelty, exoticism, misdosage, and interaction. Several factors associated with indicators were also identified, some of them defining groups of patients at risk (women, elderly, and less educated), physicians at risk (women, aged, and isolated), and contexts at risk (patient's home and disease frequently treated by the physician) of poor drug prescribing quality. CONCLUSIONS Drug prescribing by French primary care physicians appears nonoptimal, in terms of both risk of iatrogeny and waste of money. This study further documents the complexity and the multidimensionality of drug prescribing quality. It suggests that more attention must be paid to patients' and physicians' risk factors for poor drug prescribing quality if educational programs and regulatory processes are to succeed in promoting safer and more cost-effective practices.

Abstract
The aim of this study was to investigate the following in a large population of French patients with chronic hepatitis C: the geographical distribution of hepatitis C virus (HCV) genotypes; the relationship between HCV genotypes and epidemiological characteristics; severity of the disease; and response to interferon (IFN) therapy. Data from 14 tertiary referral centres, corresponding to 1872 patients with chronic hepatitis C, were prospectively collected from 1989 to 1997. HCV genotyping was performed using the line probe assay (LiPA). HCV genotypes 1b, 3, 1a, 2, 4 and a mixed infection were found in 41%, 22%, 16%, 11%, 4% and 4% of our population, respectively. HCV genotype distribution was homogeneous, except for genotype 2 that was found more frequently in the southwest than in the other regions (21% vs 9.2%) (P=0.001). HCV distribution was associated with gender, age, and source and duration of infection. In multivariate analysis, these correlations were related to the source of infection, which was the only independent factor significantly associated with genotype (P=0.001). Genotype 1b was significantly more common in patients with cirrhosis, but in multivariate analysis cirrhosis was independently related to older age at exposure and longer duration of infection (P=0.001). A sustained response to IFN therapy was observed in 11% of patients infected with genotypes 1a or 1b vs 32% of those infected with genotypes 2 or 3 (P=0.001). This study shows that HCV genotype is mainly related to the source infection, but not to the intrinsic pathogenicity of HCV, and is a strong predictor of sustained response to therapy.

Abstract
OBJECTIVE The purpose of this study was to prospectively determine any differences in vascular and liver enhancement between patients with cirrhosis and patients without cirrhosis during both the arterial and portal venous phases on dual-phase helical CT. SUBJECTS AND METHODS Fifty-eight patients with histologically proven cirrhosis (group 1) and 88 without cirrhosis (group 2 = normal findings on CT, group 3 = metastases, group 4 = other liver diseases) underwent dual-phase helical CT of the liver. Attenuation values of liver and vessels were measured on unenhanced scans and on scans obtained during the arterial and portal venous phases. The mean enhancement values per time interval (5 sec) were determined. Results were analyzed taking into account various intrinsic patient parameters. RESULTS We found no statistically significant difference in terms of mean vascular enhancement and mean liver enhancement during the arterial imaging phase for each time interval among all the groups. The mean peak enhancement and mean liver enhancement during the portal venous phase were significantly lower in group 1 than in other groups. Time to peak enhancement was significantly delayed in group 1. CONCLUSION In spite of the hepatic arterial buffer response, mean liver enhancement during the arterial phase was not significantly different in patients with cirrhosis compared with patients without cirrhosis. Although portal vein enhancement did not differ significantly, enhancement of cirrhotic liver was significantly lower during the portal venous phase and delayed, presumably because of decreased peripheral portal perfusion. The contrast injection protocol may be tailored to optimize conspicuity of hypovascular tumor.
