Abstract
A prospective, randomised, multicentre, single-blind phase 3 study was performed to assess the safety of a vaccination schedule consisting of two vaccinations (21-35 days apart) with the tick-borne encephalitis (TBE) vaccine FSME-IMMUN "adults" (five consecutive lots) in comparison to another licensed TBE vaccine (Encepur), with polygeline) (two lots) in healthy volunteers (n=3966) aged 16-65 years. The safety of the third vaccination with FSME-IMMUN "adults" (6 months after the first vaccination) was investigated in a follow-up study on the same population (n=3705) and TBE antibody titres were analysed pre- and post-vaccination in a subgroup of volunteers (n=564). Following the first vaccination, the overall incidence of fever (> or =38.0 degrees C) was 0.8% in the FSME-IMMUN "adults" study group and 5.6% in the comparator study group; fever was mainly mild. The fever rate after the second vaccination was 0.6% and 0.5% in the two study groups, respectively. Local and systemic reactions after the first vaccination occurred with a lower frequency in the FSME-IMMUN "adults" study group than in the comparator group. Upon analysing the tolerability of the third vaccination with FSME-IMMUN "adults", similar results were determined in both study groups of volunteers previously vaccinated with FSME-IMMUN "adults" or with the comparator vaccine. The immunogenicity results demonstrated similar seroconversion rates (as determined by ELISA or neutralization test) before and after the third vaccination in the FSME-IMMUN "adults" group and in the comparator group respectively. The results of both studies demonstrate that: (1) FSME-IMMUN "adults" is safe and highly immunogenic, (2) all five production lots of FSME-IMMUN "adults" were consistent with respect to a low rate of adverse events, (3) FSME-IMMUN "adults" induces considerably lower adverse reaction rates than the comparator vaccine after the first vaccination, and (4) two vaccinations with the comparator vaccine can be successfully followed by a third vaccination with FSME-IMMUN "adults".

Abstract
BACKGROUND Polymerase chain reaction (PCR) detection of herpesvirus DNA in cerebrospinal fluid (CSF) is an important tool in the diagnosis of central nervous system (CNS) syndromes. The corresponding viral infections present with diverse clinical signs, which are often classical although no sign can be considered as specific. This retrospective study aims to describe atypical symptoms in patients with herpesvirus DNA detected in CSF by PCR. A total of 3452 cerebrospinal fluid samples from patients with suspected herpesvirus infection of the CNS were investigated between 1998 and 2003 in our clinical virology laboratory. "In-house" PCRs for each herpesvirus [herpes simplex virus (HSV), varicella zoster virus (VZV), cytomegalovirus (CMV), Epstein Barr virus (EBV), or human herpes virus 6 (HHV6)] were used until 2001 and a commercially available "Herpes Consensus PCR" was used thereafter. One of the five herpesviruses investigated in this study was found in 71 (2.1%) of CSF samples (37 HSV, 14 VZV, 1 CMV, 9 EBV and 10 HHV6). These samples were obtained from 62 patients whose clinical findings were generally consistent with the PCR data. However, some little known features of herpesvirus-related symptoms, such as partial seizure associated with HSV infection, and unusual VZV or HHV6-related myelitis were also observed.

Abstract
BACKGROUND Laparoscopic colorectal resection may induce bladder and sexual dysfunction secondary to injury to the autonomic nervous system. The aim of this study was to evaluate urinary and sexual function in male patients after laparoscopic colorectal resection for diverticular disease. METHODS From January 1997 to March 2002, we performed a retrospective analysis of urinary and sexual function in 56 consecutive male patients who had undergone laparoscopic colorectal resection for diverticular disease. Preoperative and 6-month postoperative assessment was carried out using data collected via standardized postal questionnaires. RESULTS Three patients were excluded (one had a prior prostatectomy, one had Peyronie's disease, and one was treated with neuroleptics). Fifty-three patients with a mean age of 54 A+/- 2 years were included in the study. There were no conversions. The morbidity rate was 9.4%. Mean follow-up was 27 A+/- 2 months. There was no significant difference in preoperative and postoperative urinary function. Fifty-one patients (96%) were sexually active preoperatively and were still sexually active postoperatively. Compared with the preoperative period, postoperative impairment of libido, erection, ejaculation, and orgasm were not significant. Every patient was able to achieve ejaculation after the intervention, and no retrograde ejaculations were reported. One patient was unable to have an erection after the intervention. CONCLUSION Laparoscopic colorectal resection for diverticular disease does not significantly impair urinary and sexual function.

Abstract
The presence and the quantity of hepatitis C virus (HCV) RNA were investigated in saliva and serum of patients infected with both HCV and human immunodeficiency virus (HIV). Paired serum and saliva samples were collected from 59 HIV-HCV coinfected patients. HCV RNA was detected by nested-PCR, using primers derived from the 5' non-coding region of HCV, and positive results were quantified using the b-DNA method. HCV RNA was detected in the saliva of 22/59 (37.3%) patients, with a mean level of 1.15 x 10(6) genome equivalents/ml; there was no correlation of salivary positivity with immune status (CD4 cell count), age or HIV risk group, but there was with gender (19/38 [50%] positive results in male, compared to 3/21 [14.3%] in female, P = 0.007). HCV RNA was detected in the serum of 45/59 (76.3%) patients at a higher level (mean of 2.52 x 10(7) genome equivalents/ml) compared to saliva. Positivity was not correlated with age, gender or CD4 + cell count. There was a correlation between qualitative saliva and serum results (P = 0.003), but not between quantifications (P = 0.57). This first study reporting significant amounts of HCV RNA in saliva could have important implications for HCV epidemiology.

Abstract
OBJECTIVE The purpose of this study was to explore both the personality characteristics and the symptoms of personality disorder of adolescent suicide attempters, as well as the relationship between personality variables and hopelessness in this population. METHOD Two sample populations were used in this study. First, 102 adolescent suicide attempters between 13 and 18 years of age completed the Millon Adolescent Personality Inventory (MAPI) and the Hopelessness Scale for Children (HSC). A second group of 35 adolescent suicide attempters were administered the HSC and the revised Diagnostic Interview for Borderlines (DIB). RESULTS No distinctive personality characteristics or symptoms of personality disorders were found. However, affective distress seemed to be the most prominent feature in the presentation of these adolescents. Additionally, high scores on the HSC were associated with elevated scores on the Personality Style scales of the MAPI and higher (more dysfunctional) scores on Affect Regulation on the DIB. CONCLUSIONS The results suggest that clinicians should focus most on the personality characteristic of sensitivity and on affect regulation when assessing adolescent suicide attempters. In addition, hopelessness is important to systematically assess because it appears to be related to a variety of dysfunctional personality characteristics that may affect follow-up outcome.

Abstract
The prevalence of GB virus C (GBV-C)/ hepatitis G virus (HGV) RNA and antibodies to the structural E2 protein was investigated in a cohort of HIV-1 infected patients. Of 346 individuals, RNA was detected in 143 and E2 antibodies were detected in 73, for an overall prevalence of 62.4%. Intravenous drug use and homosexuality were identified as major transmission risk factors. GBV-C/HGV RNA prevalence was associated with hepatitis B coinfection, whereas antibodies to E2 were associated with older age and lower CD4+ cell counts. GBV-C/HGV infection was frequent in this group of HIV-infected patients and was associated with older age, lower CD4 + cell counts, and the presence of hepatitis B surface antigen.

Abstract
The correlation between response to antiviral therapy and pretreatment viral load in patients with chronic hepatitis C has prompted the development of quantitative assays to measure viral load. The aim of our study was to assess the clinical relevance of the newly developed semiautomated PCR system COBAS HCV MONITOR version 2.0 in comparison with (i) the AMPLICOR HCV MONITOR version 1.0 assay, which underestimates RNA concentration of hepatitis C virus (HCV) genotypes 2 to 6, and (ii) the QUANTIPLEX HCV RNA version 2.0 assay, which achieves equivalent quantification for each HCV genotype, with samples from 174 patients diagnosed with chronic hepatitis C before therapy. The level and range of quantification measured with AMPLICOR HCV MONITOR version 1.0 were 1 log lower than when measured with the COBAS HCV MONITOR version 2.0, at 0.261 x 10(6) RNA copies/ml (range, 0.001 x 10(6) to 2.50 x 10(6) RNA copies/ml) and 4.032 x 10(6) RNA copies/ml (range, 0.026 x 10(6) to 72.6 x 10(6) RNA copies/ml), respectively. The two assays showed a poor correlation (r(2) = 0.175). The level and range of quantification were similar when measured with the COBAS HCV MONITOR version 2.0 and QUANTIPLEX HCV RNA version 2.0 assays, at 3.03 x 10(6) RNA copies/ml (range, 0.023 x 10(6) to 72.6 x 10(6) RNA copies/ml) and 4.91 Meq/ml (range, 0.200 to 49.5 Meq/ml), respectively. The two assays showed a strong correlation (r(2) = 0. 686) for each HCV genotype. The duration of treatment (6 or 12 months) is modulated according to HCV genotype and viral load. Our results indicate that COBAS HCV MONITOR version 2.0 and QUANTIPLEX HCV RNA version 2.0 assays showing an equal dynamic range for each HCV genotype are suitable tools to assess patients before therapy.

Abstract
Idiopathic right ventricular outflow tract tachycardia is readily amenable to radiofrequency catheter ablation. However, treatment modalities for left ventricular outflow tract tachycardia are not well defined. Out of 37 patients with idiopathic outflow tract tachycardia referred for catheter ablation, in 3 patients tachycardia originated from the left ventricular outflow tract. On the surface ECG, all left ventricular tachycardias exhibited an inferior axis with a predominant negative QRS complex in lead I. Heart rate during tachycardia ranged from 115 to 170 beats/min. During electrophysiological testing, 1 patient had inducible tachycardia on orciprenaline challenge, 1 patient had inducible tachycardia at baseline, and 1 patient had incessant tachycardia. In two patients, earliest ventricular activation was recorded from the endocardial left ventricular outflow tract at an anterolateral and an anterior site, respectively. A distinct high frequency spike preceded the QRS onset by 66/78 ms. Application of radiofrequency energy successfully eliminated tachycardia at these sites. In one patient, tachycardia originated from the epicardial left ventricular outflow tract. Mapping of the anterior interventricular vein revealed a fractionated low amplitude signal occurring 46 ms before QRS onset. After failure of catheter ablation from the corresponding endocardial site, successful minimally invasive surgical focal cryoablation of the epicardial target region was performed. During a follow-up period ranging from 7 to 12 months, all patients remained free of tachycardia. In conclusion, ventricular tachycardia arising from the left ventricular outflow tract may require endo- and epicardial mapping. Successful treatment is achieved by radiofrequency catheter ablation or minimally invasive surgical cryoablation.

Abstract
Seven patients co-infected with hepatitis B virus (HBsAg and HBeAg carriers, quantifiable HBV DNA with the bDNA technic) and human immunodeficiency virus received a triple antiretroviral combination therapy, including lamivudine (150 mg twice a day). Hepatitis B viral load rapidly became undetectable in 6/7 patients. It remained below the level of detection in 2 subjects, after 20 and 22 months of treatment, with one of them achieving HBeAg/anti-HBe seroconversion. However, in the other 4 individuals, hepatitis B viremia increased again after 8 to 16 months of lamivudine-containing regimen. The last patient was a non-responder. The 4 relapsers developed a double mutation Leu(528) for Met(528) and Met(552) for Val(552), on hepatitis B virus polymerase, either concomitant (M8 and M16) with a hepatitis B virus DNA increase, or 2 months earlier (M10 and M12). The high frequency of hepatitis B virus resistance to lamivudine emphasizes the necessity of identifying more effective strategies, such as double combination therapies.

Abstract
UNLABELLED The instruments currently used in endoscopic surgery are limited by several factors, in particular their reduced working space. In order to develop instruments with manifold degrees of freedom (DOF), the elementary actions performed by the existing instruments must be defined. MATERIAL AND METHODS We have broken down into elementary movements the actions performed by the currently used instruments and analyzed them by measuring the strain on the instruments and on their working volume. The elementary actions were performed in vitro (Pelvitrainer) on an animal model (pig) and also in the course of clinical practice. A total of 6,750 measurements were carried out for the following actions: grasping, cutting, dissecting, suturing and knotting. RESULTS The largest working volumes were measured for the knotting and suturing actions (198 degrees in axial rotation and 69 degrees in lateral translation). The range of the working space was between 8 degrees and 52 degrees. Forces exerted on the instrument were between 0.5 and 12 Newton (N). Forces exerted on the headpoint were between 0.4 and 10.5 N whereas the friction forces were between 0.5 and 1.5 N. COMMENTS By analyzing the elementary actions of endoscopic surgery, we were able to quantify the directions and dimensions of forces sustained by the instruments and were also able to measure the working volume involved when performing the main actions in endoscopic surgery. The results obtained provide a basis for the development of more sophisticated instruments.

Abstract
We report here the results of a 2-year study on the prenatal diagnosis of viral infections in Strasbourg. This screening was carried out by virus isolation, by PCR assay, or by detection of IgM fetal antibody for 98 pregnant women at risk of transmitting one of the viruses that causes fetal disease such as parvovirus B19 (B19), Herpesviruses [cytomegalovirus (CMV), varicella-zoster virus, herpes simplex virus] and rubella virus. A viral etiology was proven in 7 out 98 cases: PCR applied to B19 DNA detection was positive in 5 amniotic fluids (AF), 2 fetal serums and one ascitic liquid. The diagnosis of 2 cases of CMV infection was obtained by both PCR and virus isolation in AF from twins fetuses. The detection of specific IgM in maternal serum or fetal serum is useful to achieve the diagnosis but serological tests on other samples have no efficiency. No virus was found in any other specimen, but the genome of Toxoplasma gondii was detected by PCR in 1 of 17 AF samples analyzed at the Institut de Parasitologie. These findings show that PCR assay is a sensitive method for the positive diagnosis of intrauterine infection and promises to careful follow-up of the pregnancy.

Abstract
Prevalence of GBV-C/HGV was determined in a cohort of HIV-infected patients, via a reverse transcription-polymerase chain reaction detection of RNA in serum, amplifying the NS5 region of GBV-C/HGV genome. GBV-C/HGV RNA was detected in 143 (37.7%) of 379 patients, with similar results in the different HIV risk groups: 25/56 (44.6%) in intravenous drug users, 66/161 (41%) in homo- and bisexual men, 35/108 (32.4%) in heterosexual patients, 6/20 (30%) in transfusion recipients (P=0.41). There was no difference according to the presence or absence of hepatitis C virus infection. In univariate analysis, GBV-C/HGV genome prevalence was lower in patients over 50 years old (18.2%), compared to other age groups (20-29 years: 34.2%; 30-39 years: 44.3%; 40-49 years: 36.7%, P=0.03), as well as in patients with normal CD4 cell count (29.2% vs. 45.4% between 200-500/mm3, and 35.3% below 200 CD4/mm3, P=0.012) and individuals with a chronic hepatitis B. However, in the multivariate analysis, the only prognostic factor of GBV-C/HGV RNA positivity was the presence of a chronic hepatitis B, compared to the absence of any HBV marker, or a previous exposition to HBV (presence of anti-HBc and/or anti-HBs, absence of HBsAg), or the presence of anti-HBs alone.

Abstract
BACKGROUND Intraoperative bleeding is the main complication and main cause of conversion to open surgery during laparoscopic splenectomy (LS). We present the advantages of the lateral approach and the use of the ultrasonic shears (US) for achieving a safer vascular control. METHODS We have performed a total of 48 LS using several approaches. In our initial experience 10 patients underwent surgery with an anterior approach. In the second series of 18 patients, we used a manually assisted procedure. In the last 20 patients, we employed a technique with a full lateral position. Only three ports have been used. The major part of the dissection was conducted from behind, thus allowing a safer vascular control. The division of short gastric vessels and lower pole vessels was performed using US. The main vascular pedicle was stapled. The spleen was removed through a short Pfannenstiel incision. There were 9 males and 11 females with a mean age of 36 years (range, 18-71 years). Fourteen had immune thrombocytopenic purpura (ITP); two had an HIV-infection-related purpura; two had an autoimmune hemolytic anemia; and two had a spherocytosis. RESULTS All the 20 LS were completed. The average splenic weight was 274 g (range, 162-1,400 g). In all but one patient, the intraoperative blood loss was less than 60 ml, and was none in six patients (average, 51 ml). In our initial series of 10 patients surgically treated with an anterior approach, the average blood loss was 180 ml, and it was 230 ml in the series of hand-assisted procedures. The average operative time was 127 min (range, 70-220 min), including the time required by the change of position and the Pfannenstiel incision. There was no mortality. All but one patient had an uneventful postoperative course. The HIV-infected patient had a severe postoperative pancreatitis. In those patients with an uncomplicated course, the average postoperative stay was 4.3 days (range, 2-8 days). CONCLUSIONS The lateral position with a posterior approach to splenic vessels allows for safe vascular control. The use of US results in a gain of time and safety. The average intraoperative bleeding of this series is much lower than that observed in our previous experience and in other published series.

Abstract
Prevalence of GBV-C/HGV was determined in a cohort of HIV-infected patients, via a reverse transcription-polymerase chain reaction detection of RNA in serum, amplifying the NS5 region of GBV-C/HGV genome. GBV-C/HGV RNA was detected in 143 (37.7%) of 379 patients, with similar results in the different HIV risk groups: 25/56 (44.6%) in intravenous drug users, 66/161 (41%) in homo- and bisexual men, 35/108 (32.4%) in heterosexual patients, 6/20 (30%) in transfusion recipients (P=0.41). There was no difference according to the presence or absence of hepatitis C virus infection. In univariate analysis, GBV-C/HGV genome prevalence was lower in patients over 50 years old (18.2%), compared to other age groups (20-29 years: 34.2%; 30-39 years: 44.3%; 40-49 years: 36.7%, P=0.03), as well as in patients with normal CD4 cell count (29.2% vs. 45.4% between 200-500/mm3, and 35.3% below 200 CD4/mm3, P=0.012) and individuals with a chronic hepatitis B. However, in the multivariate analysis, the only prognostic factor of GBV-C/HGV RNA positivity was the presence of a chronic hepatitis B, compared to the absence of any HBV marker, or a previous exposition to HBV (presence of anti-HBc and/or anti-HBs, absence of HBsAg), or the presence of anti-HBs alone.

Abstract
BACKGROUND Thoracoscopic sympathectomy is the most effective treatment for upper limb hyperhidrosis. However, this is offset by the occurrence of a high rate of side effects, such as embarrassing compensatory sweating. Anticipating that a technique that respects the sympathetic chain and divides only the rami communicantes may lead to fewer side effects, we assessed the technique described by R. Wittmoser, comparing it with conventional thoracoscopic sympathecomy. METHODS A total of 240 thoracoscopic sympathectomies were performed in 124 patients suffering from upper limb hyperhidrosis. Fifty-four patients underwent a conventional sympathectomy (group TS), 62 underwent division of the rami communicantes with respect to the main trunk (group SS), and 8 underwent both procedures (group TS/SS) because of accidental division of the chain during dissection. The mean follow-up is 8 months. RESULTS No recurrence was observed in group TS whereas six (5%) occurred in group SS (p < 0.05). The global rate of compensatory sweating was about the same in both groups: 72.2% in group TS and 70.9% in group SS. However, the rate of embarrassing or disabling compensatory sweating was significantly higher in group TS (50%) than in group SS (21%) (p < 0.001). CONCLUSIONS Although selective division of the rami communicantes results in a significant decrease in the rate of disturbing side effects, it also leads to recurrences that are usually not observed at that level in patients treated with the conventional technique. Therefore other means of achieving the ideal operation should be explored, that is, a technique associated with a high success rate but a minimal number of side effects.

Abstract
OBJECTIVE To review the literature on somatoform disorders in children and adolescents relevant to recertification by the American Board of Psychiatry and Neurology. METHOD The psychiatric, pediatric, and psychological literatures were searched for clinical or research articles in the past 10 years dealing with somatization and somatoform disorders. RESULTS Somatizing presentations are organized conceptually; somatization disorder, body dysmorphic disorder, hypochondriasis, conversion disorder, vocal cord dysfunction, pain disorder, and recurrent abdominal pain are described in children and adolescents; empirical evidence for treatment efficacy is scant, but clinically reasonable approaches are applied. CONCLUSION More developmentally appropriate diagnostic schemas and better outcome studies are needed in all the somatoform disorders for children and adolescents.
