Abstract
Abstract
Virus-based therapies show promise in inducing systemic anti-tumor immunity. Over the past years, modified poxviruses were developed to induce a sustained antitumoral immune response. Several studies confirm this hypothesis and report induction of T cell response against the antigen targeted by these vaccines. We previously reported MVA induced T-cell response against HPV oncoviral antigens E6 and E7 in HPV anogenital cancers (NCT03260023) and against private tumor neoantigen in ovarian and head and neck cancer. Despite these promising results the molecular and cellular mechanisms involved in vaccine response remains to be elucidated. In this work, we inquired whether EVs, well known for mediating intercellular communication, play a role in these therapeutic vaccination process. We first asked whether poxviral infection of human primary cells modifies their EV secretion properties. To this end, peripheral blood mononuclear cells (PBMCs) from healthy donors were infected with poxviral vectors, cell culture supernatants were harvested, and different isolation methods were compared for their ability to separate EVs from viral particles: ultracentrifugation, immunocapture, density gradient, velocity gradient, size exclusion chromatography and filtration. EVs size distribution and concentration were determined by nanoparticle tracking analysis (NTA) and the presence of infectious viral particles was titrated by plaque assays. Our data showed that 0.1µm filtration allowed the complete separation of EVs from infectious viral particles. All other methods showed co-isolation of EVs and infectious viral particles. Using this method, we demonstrate that infection of PBMCs with the poxviruses VACV, MVA and PCPV significantly increased the amount of secreted EVs. Next, we investigated the molecular content of EVs isolated from MVA-infected PBMCs by mass spectrometry. We observed differences in the abundance of at least 57 human proteins between EVs from infected and non-infected cells. In addition, several viral proteins, including virus-encoded payloads were detected in EVs from infected cells. We are now confirming those data with flow cytometry to detect virus-encoded payloads like tumor antigens, antigen-presenting molecules, and EV markers such as tetraspanins. The RNA content of EVs from infected and non-infected cells will be compared. Finally, EVs were isolated from murine dendritic cells infected with therapeutic pox vaccines. We are now evaluating the effects of local and systemic application of EVs in murine tumor models.

Abstract
SHORT INTRODUCTION/BACKGROUND Surgical intervention for acute testicular torsion can require either orchiopexy or orchiectomy. The decision of which surgery to perform is dependant on the amount of time that the testicle experienced ischemia and the viability of the testicle after reperfusion. OBJECTIVE It is hypothesized that (1) there is a difference in orchiectomy and orchiopexy rates between prepubertal and postpubertal males with acute testicular torsion and (2) presenting symptoms may vary between the two age groups as prepubertal males may present with atypical symptoms, which could result in delayed presentation and diagnosis. STUDY DESIGN A retrospective chart review was conducted on pediatric patients who were diagnosed with acute testicular torsion between June 2010 and August 2017. Demographic and clinical characteristics were extracted: age, ethnicity, referral pattern, primary insurance status, symptoms at presentation, prior history of ipsilateral testicular pain or intermittent torsion, recent trauma to genitalia, duration of symptoms (hours), gradual vs. acute onset of symptoms, time/weekday/season at presentation, and time interval from arrival at the study institution to surgical intervention (minutes). Patients were categorized into two groups: prepubertal group (age 1-12 years) and postpubertal group (age 13-18 years). Statistical analyses were performed using R, version 3.3.1. RESULTS Ninety-one patients were included in the study. The overall orchiectomy rate was 30.8%. More prepubertal males underwent orchiectomy than postpubertal males (42.4% vs. 24.1%, respectively). Prepubertal males were more likely to present with abdominal pain than postpubertal males (27.3% vs. 10.3%, respectively). Those who underwent orchiectomy were more likely to present with longer duration of symptoms, testicular swelling, and abdominal pain than those who underwent orchiopexy. The risk of orchiectomy decreased by 14% per 1-year increase in age (odds ratio [OR]: 0.86, 95% confidence interval [CI]: 0.94-1.00, p = .009). A steady decline in the proportion of patients undergoing orchiectomy was seen from 1 to 12 years of age. DISCUSSION This study found that prepubertal males are at higher risk for orchiectomy than postpubertal males. The risk of orchiectomy decreases by 14-16% per 1-year increase in age. Prepubertal males are more likely to present with atypical symptoms and delayed presentation and diagnosis, leading to delayed surgical intervention. It is important for providers to perform a genital examination in prepubertal males who present with abdominal pain to rule out acute testicular torsion. Patients presenting with longer duration of symptoms, testicular swelling, and abdominal pain are at higher risk for orchiectomy. No correlation was found between orchiectomy rate and ethnicity, referral status, primary insurance status, and time/weekday/season at presentation. CONCLUSION Among patients presenting to a tertiary pediatric hospital with acute testicular torsion, prepubertal males (younger than 12 years) are at higher risk for orchiectomy than postpubertal males. Prepubertal males are more likely to present with atypical symptoms which results in delayed presentation and diagnosis, leading to delayed in surgical intervention.

Abstract
A multi-energy soft x-ray pinhole camera has been designed and built for the Madison Symmetric Torus reversed field pinch to aid the study of particle and thermal-transport, as well as MHD stability physics. This novel imaging diagnostic technique combines the best features from both pulse-height-analysis and multi-foil methods employing a PILATUS3 x-ray detector in which the lower energy threshold for photon detection can be adjusted independently on each pixel. Further improvements implemented on the new cooled systems allow a maximum count rate of 10 MHz per pixel and sensitivity to the strong Al and Ar emission between 1.5 and 4 keV. The local x-ray emissivity will be measured in multiple energy ranges simultaneously, from which it is possible to infer 1D and 2D simultaneous profile measurements of core electron temperature and impurity density profiles with no a priori assumptions of plasma profiles, magnetic field reconstruction constraints, high-density limitations, or need of shot-to-shot reproducibility. The expected time and space resolutions will be 2 ms and <1 cm, respectively.

Abstract
The concept of parity describes the inversion symmetry of a system and is of fundamental relevance in the standard model, quantum information processing, and field theory. In quantum electrodynamics, parity is conserved and large field gradients are required to engineer the parity of the light-matter interaction operator. In this work, we engineer a potassiumlike artificial atom represented by a specifically designed superconducting flux qubit. We control the wave function parity of the artificial atom with an effective orbital momentum provided by a resonator. By irradiating the artificial atom with spatially shaped microwave fields, we select the interaction parity in situ. In this way, we observe dipole and quadrupole selection rules for single state transitions and induce transparency via longitudinal coupling. Our work advances the design of tunable artificial multilevel atoms to a new level, which is particularly promising with respect to quantum chemistry simulations with near-term superconducting circuits.

Abstract
The neuropilin-plexin receptor complex regulates tumor cell migration and proliferation and thus is an interesting therapeutic target. High expression of neuropilin-1 is indeed associated with a bad prognosis in glioma patients. Q-RTPCR and tissue-array analyses showed here that Plexin-A1 is highly expressed in glioblastoma and that the highest level of expression correlates with the worse survival of patients. We next identified a developmental and tumor-associated pro-angiogenic role of Plexin-A1. Hence, by using molecular simulations and a two-hybrid like assay in parallel with biochemical and cellular assays we developed a specific Plexin-A1 peptidic antagonist disrupting transmembrane domain-mediated oligomerization of the receptor and subsequent signaling and functional activity. We found that this peptide exhibits anti-tumor activity in vivo on different human glioblastoma models including glioma cancer stem cells. Thus, screening Plexin-A1 expression and targeting Plexin-A1 in glioblastoma patients exhibit diagnostic and therapeutic value.

Abstract
In experiments with superconducting quantum circuits, characterizing the photon statistics of propagating microwave fields is a fundamental task. We quantify the n^{2}+n photon number variance of thermal microwave photons emitted from a blackbody radiator for mean photon numbers, 0.05≲n≲1.5. We probe the fields using either correlation measurements or a transmon qubit coupled to a microwave resonator. Our experiments provide a precise quantitative characterization of weak microwave states and information on the noise emitted by a Josephson parametric amplifier.

Abstract
The two-color soft x-ray (SXR) tomography diagnostic on the Madison Symmetric Torus is capable of making electron temperature measurements via the double-filter technique; however, there has been a 15% systematic discrepancy between the SXR double-filter (SXRDF) temperature and Thomson scattering (TS) temperature. Here we discuss calibration of the Be filters used in the SXRDF measurement using empirical measurements of the transmission function versus energy at the BESSY II electron storage ring, electron microprobe analysis of filter contaminants, and measurement of the effective density. The calibration does not account for the TS and SXRDF discrepancy, and evidence from experiments indicates that this discrepancy is due to physics missing from the SXRDF analysis rather than instrumentation effects.

Abstract
Displacement of propagating quantum states of light is a fundamental operation for quantum communication. It enables fundamental studies on macroscopic quantum coherence and plays an important role in quantum teleportation protocols with continuous variables. In our experiments, we have successfully implemented this operation for propagating squeezed microwave states. We demonstrate that, even for strong displacement amplitudes, there is no degradation of the squeezing level in the reconstructed quantum states. Furthermore, we confirm that path entanglement generated by using displaced squeezed states remains constant over a wide range of the displacement power.

Abstract
OBJECTIVES Food insecurity, defined as the limited or uncertain availability of nutritious and safe foods, is a complex phenomenon and is linked to poor nutrition and diet-sensitive chronic diseases. Dietary patterns that include saturated fats and meat products are potential risk factors for the progression of peripheral arterial disease (PAD). This study explored whether there is a relationship between food insecurity and PAD among a national sample of older adults. DESIGN We conducted a cross-sectional data analysis using data from the 1999-2004 National Health and Nutrition Examination Survey (NHANES). Food security was assessed using the US Household Food Security Survey Module. Bivariate analyses were conducted using the Rao-Scott Chi-square test to examine associations between PAD and sociodemographic variables. Multivariable generalized logistic regression was employed to assess the effect of food security on the presence of PAD, with adjustment for respondent's socio demographic characteristics. PARTICIPANTS A total of 2,027 adults with PAD were included (Ankle Brachial Index (ABI) score ≤ 0.90).We excluded participants less than 60 years of age. RESULTS Compared to older adults who are food secure, those who are food insecure have an increased risk for PAD. Food insecurity is associated with peripheral arterial disease among older adults (adults adjusted odds ratio, 1.50 [95% CI 1.11-2.03). CONCLUSION Older adults with peripheral arterial disease are experiencing food insecurity. While nutrition and PAD are not well-defined, previous literature indicates there is a connection between food insecurity and diet-sensitive chronic diseases (diabetes and hypertension) which are risk factors for PAD. Food insecurity should be taken into consideration when treating older adults with PAD to help decrease poor health outcomes that are linked to an insufficient amount of nutritious foods.

Abstract
BACKGROUND The treatment of unicompartmental arthritis in younger patients is challenging. The aim of this study is to report final safety and efficacy analysis results for the iForma patient-specific interpositional device, which is designed for the treatment of isolated medial or lateral compartment arthritis of the knee. METHODS From June 2005 to June 2008 78 subjects (42 men, 36 women) received an iForma implant. The mean age was 53 years, the mean Body Mass Index 29.0. We surveyed the WOMAC scores, the visual analog pain scale and the Knee Society Scores. RESULTS The mean follow up was 16.4 months. The mean WOMAC knee scores increased from 48.3 before surgery to 71.3 after 24 months. A reduction in pain was achieved for all five pain measures using a standard visual analog scale (VAS). Knee Society Knee Score improved from 39.2 before to 61.9 24 month after surgery. The Knee Society Function Scores improved form preoperative 64.5 to 82.5 2 years postoperative. The preoperative range of motion could be restored. The overall revision rate was 24%. 15 implants were removed early, 4 knees were revised without implant removal. CONCLUSION Within narrow indication of patients with unicompartmental disease, the iForma device can provide improvement in knee function and reduction in pain, however, with a significant higher risk of early revision compared to traditional arthroplasty. Respecting this limitation it may be an alternative option for arthritic patients with unicompartmental disease who have contraindications to High Tibial Osteotomy or are too young for knee replacement; the iForma device further has the distinct advantage of time and cost saving compared to those procedures.

Abstract
We report about a 44-year-old woman who presented at our Orthopaedic Department suffering from persisting pain and a tumor of the right knee after open articulosynovectomy. MRI did not clarify the entity at all. The X-ray examination could identify an inlying compress after a synovectomy in 1999. The intra-articular foreign body could be removed by open revision surgery.

Abstract
AIM: Anti-Saccharomyces cerevisiae antibodies (ASCA), anti-nuclear associated anti-neutrophil antibodies (NANA) and antibodies to exocrine pancreas (PAB), are serological tools for discriminating Crohn’s disease (CrD) and ulcerative colitis (UC). Like CrD, coeliac disease (CoD) is an inflammatory bowel disease (IBD) associated with (auto) antibodies. Performing a multicenter study we primarily aimed to determine the performance of ASCA, NANA and PAB tests for IBD diagnosis in children and adults, and secondarily to evaluate the prevalence of these markers in CoD.
METHODS: Sera of 109 patients with CrD, 78 with UC, 45 with CoD and 50 healthy blood donors were retrospectively included. ASCA, NANA and PAB were detected by indirect immunofluorescence (IIF).
RESULTS: ASCA+/NANA- profile displayed a positive predictive value of 94.2% for CrD. Detection of ASCA was correlated with a more severe clinical profile of CrD and treatment of the disease did not influence their serum levels. ASCA positivity was found in 37.9% of active CoD. PAB were found in 36.7% CrD and 13.3% CoD patients and were not correlated with clinical features of CrD, except with an early onset of the disease. Fifteen CrD patients were ASCA negative and PAB positive.
CONCLUSION: ASCA and PAB detected by IIF are specific markers for CrD although their presence does not rule out a possible active CoD. The combination of ASCA, NANA and PAB tests improves the sensitivity of immunological markers for CrD. Repeating ASCA, NANA, and PAB testing during the course of CrD has no clinical value.

Abstract
INTRODUCTION Deficiencies in components of the classical pathway of complement activation are strong risk factors for lupus erythematosus (LE).Yet, it has not been addressed whether the conventional measurements of the serum hemolytic CH50 activity and antigenic concentrations of C3 and C4 are sufficient to asses a deficiency in C4A, C4B or C2 components, the most common deficiencies associated with LE. PATIENTS AND METHODS In a retrospective series, we performed complement analyses in 35 patients with LE who were systematically screened for a complement deficiency. The majority of patients had cutaneous LE with mild systemic involvement and no complement consumption. Of 25 patients (72%) with complement deficiency we found 13 with a partial C4A deficiency, 2 with a complete C4A deficiency, 6 with a partial C4B deficiency, 2 with a complete C4B deficiency and 2 with a combined partial C2 and C4A deficiency. RESULTS The total complement activity (CH50) was decreased in only one out of two patients with complete C4B deficiency. CH50 level was found to be low-normal (35-38 U/ml(-1)) in one patient with partial C4B deficiency, one patient with complete C4B deficiency and both patients with combined partial C4A and C2 deficiency. Total C4 levels were normal in 9 out of 13 the patients with a partial C4A deficiency and in 2 out of 6 patients with a complete C4B deficiency. The antigenic concentration of C3 was low in only 1 patients with a complete C4B deficiency and within the normal range in all the others patients. Overall, 50% of the patients had normal or elevated C3, C4, and CH50 levels. DISCUSSION This study emphasizes that the usual measurements of CH50, C3 and C4 levels are not adequate to detect a C4 and/or C2 deficiency in patients with LE. In epidemiologic or investigative studies addressing the prevalence of complement deficiency, more elaborated diagnostic tests, such as C4 protein allotyping, C2 level measurement and genetic screening for type I C2 deficiency should also be performed.

Abstract
We report a new measurement of the exclusive electroproduction reaction gamma(*)p-->pi(0)p to explore the evolution from soft nonperturbative physics to hard processes via the Q(2) dependence of the magnetic (M(1+)), electric (E(1+)), and scalar (S(1+)) multipoles in the N-->Delta transition. 9000 differential cross section data points cover W from threshold to 1.4 GeV/c(2), 4pi center-of-mass solid angle, and Q(2) from 3 to 6 GeV(2)/c(2), the highest yet achieved. It is found that the magnetic form factor G(M)(*) decreases with Q(2) more steeply than the proton magnetic form factor, the ratio E(1+)/M(1+) is small and negative, indicating strong helicity nonconservation, and the ratio S(1+)/M(1+) is negative, while its magnitude increases with Q(2).

Abstract
INTRODUCTION Osteonecrosis of the femoral head is a local destructive disease with progression into devastating stages. Left untreated it mostly leads to severe secondary osteoarthrosis and early endoprosthetic joint replacement. Core decompression by exact drilling into the ischemic areas can be performed in early stages according to Ficat or ARCO. Computer-aided surgery might enhance the precision of the drilling and lower the radiation exposure time of both staff and patients. The aim of this study was to evaluate the precision of the fluoroscopically based VectorVision navigation system in an in vitro model. MATERIALS AND METHODS Thirty sawbones were prepared with a defect filled up with a radiopaque gypsum sphere mimicking the osteonecrosis. Twenty sawbones were drilled by guidance of an intraoperative navigation system VectorVision (BrainLAB, Munich, Germany) and 10 sawbones by fluoroscopic control only. RESULTS No gypsum sphere was missed. There was a statistically significant difference regarding the three-dimensional deviation (Euclidian norm) as well as maximum deviation in x-, y- or z-direction (maximum norm) to the desired mid-point of the lesion, with a mean of 0.51 and 0.4 mm in the navigated group and 1.1 and 0.88 mm in the control group, respectively. Furthermore, significant difference was found in the number of drilling corrections as well as the radiation time needed: no second drilling or correction of drilling direction was necessary in the navigated group compared to 1.4 in the control group. The radiation time needed was less than 1 s compared to 3.1 s, respectively. CONCLUSION The fluoroscopy-based VectorVision navigation system shows a high feasibility of computer-guided drilling with a clear reduction of radiation exposure time and can therefore be integrated into clinical routine. The additional time needed is acceptable regarding the simultaneous reduction of radiation time.

Abstract
BACKGROUND B cell activation may result in an increased secretion of immunoglobulin free light chains (FLCs) in autoimmune diseases. OBJECTIVE To analyse serum FLC levels in patients with rheumatoid arthritis and in those with primary Sjögren's syndrome (pSS). PATIENTS AND METHODS Blood samples were collected from 80 healthy blood donors, 50 patients with rheumatoid arthritis and 139 patients with pSS. Serum FLC level was measured using a new quantitative immunoassay. RESULTS Mean (standard error (SE)) serum kappa and lambda FLC levels were significantly higher in patients with rheumatoid arthritis and in those with pSS than in controls (kappa : 18.9 (1.1) and 16.3 (1.4) v 10.5 (0.4) mg/l, p<0.001 and p = 0.001, respectively; lambda: 16.7 (1.2) and 19.3 (1.5) v 11.6 (0.6) mg/l, p<0.001 for both). 18 (36%) patients with rheumatoid arthritis and 31 (22.3%) patients with pSS had abnormal serum FLC levels (increased kappa or lambda levels and abnormal ratio of kappa:lambda). Serum kappa and lambda levels were correlated with other B cell activation markers in both diseases. FLC levels increased with disease activity, because, unlike total gammaglobulin and immunoglobulin G levels, they were significantly correlated with Disease Activity Score 28 in patients with rheumatoid arthritis (p = 0.004 for kappa, p = 0.05 for lambda) and with extraglandular involvement in pSS (p = 0.01 for kappa, p = 0.04 for lambda). CONCLUSION FLC levels are increased and correlate with disease activity in patients with rheumatoid arthritis and in those with pSS, two diseases in which increased risk of lymphoma could result from persistent B cell activation and disease activity. Further studies are required to determine whether FLC assessment could represent a relevant biomarker for response to treatment (especially B cell depletion) and for the risk of lymphoma in autoimmune diseases.

Abstract
INTRODUCTION Anti-PM/Scl antibodies (Anti-PM/Scl) represent a rarely encountered type of antinuclear antibodies. They have mainly been reported in association with idiopathic inflammatory myositis - systemic sclerosis overlap syndromes (also called scleromyositis or sclerodermatomyositis) but also with polymyositis, dermatomyositis and systemic sclerosis without features of overlap syndromes. Studies concerning characteristics of patients with anti-PM/SCl are rare and include small numbers of patients. PATIENTS AND METHODS Retrospective review of clinical and biological characteristics of 14 patients with anti-PM/Scl in two University Hospitals: one in Belgium (Erasme Hospital, Bruxelles) and one in France (Hautepierre Hospital, Strasbourg). RESULTS Seven patients were identified in Erasme and 7 in Strasbourg: 5 with systemic sclerosis-(dermato)myositis overlap syndromes, 4 with dermatomyositis, 1 with polymyositis, 3 with systemic sclerosis, 1 with primary Sjögren's syndrome. The most frequently observed clinical characteristics (85% of patients) were: pulmonary interstitial disease and arthralgia or arthritis. No patient of our series died or developed cancer (mean follow-up:6.1 years). CONCLUSIONS Our study failed to identify an homogeneous clinical pattern in patients with anti-PM/Scl, except for 2 characteristics shared by 85% of the patients. This lack of homogeneity is in agreement with preceding literature. We confirm the favourable prognosis associated with the presence of anti-PM/Scl, despite the high incidence of interstitial pulmonary disease. The absence of cancer associated with presence of anti-PM/Scl represents a partial explanation. Finally, we report herein the second case of primary Sjögren's syndrome associated with anti-PM/Scl.

Abstract
According to international criteria, autoimmune hepatitis (AIH) type 1 is characterized by the presence of antinuclear or anti-smooth muscle antibodies (SMA) with F-actin specificity. SMA have been found in 85% of AIH patients, but are not specific to this disease, and anti-F-actin specificity is not always verified when SMA are detected. The objective of this study was to determine the diagnostic value of anti-F-actin antibodies in a large population. A multicenter study involving 12 clinical centers was performed. Patients were selected on the basis of the presence of F-actin SMA detected by indirect immunofluorescence (IIF) on rat liver-kidney-stomach sections and was confirmed by IIF on Hep2 cells treated with colchicine, or F-actin dot-blot. The clinical status of patients was determined from their medical records. One hundred sixty-eight patients were included: 76% women, 24% men; mean age of 45 years (range, 2-88 years), with a bimodal age distribution. Sixty percent had AIH type 1, and 40% had another disease. In the group of women younger than 25 years, 90% had AIH type 1. Other pathologies associated with antiactin were other liver diseases (19%), including viral hepatitis C (7%), and non-liver diseases (21%), including connective tissue diseases (12%). Antibody titers were higher in AIH than in other diseases. Antiactin antibodies are of major diagnostic value in AIH, especially in young women; they may be found in other disease settings, but mostly at low levels.

Abstract
OBJECTIVE To investigate the prevalence of anti-cyclic citrullinated peptide (anti-CCP) and anti-keratin antibodies (AKA) in patients with primary Sjögren's syndrome. METHODS 149 patients with a diagnosis of primary Sjögren's syndrome according to the European/American consensus criteria were recruited from three French medical centres. The presence of anti-CCP was determined by enzyme linked immunosorbent assay and of AKA antibodies by indirect immunofluorescence. Radiographs of hands and feet were evaluated at the time of anti-CCP analysis. RESULTS Six patients with radiological erosions and nine patients with non-erosive arthritis fulfilling ACR criteria for rheumatoid arthritis were thought to have rheumatoid arthritis and secondary Sjögren's syndrome, while 134 were considered to have primary Sjögren's syndrome (mean (SD) disease duration, 11.1 (6.6) years). Of these, 80 tested positive for IgM rheumatoid factor (RF) (59%), 10 (7.5%) for anti-CCP, 7 (5.2%) for AKA, and 5 (3.7%) for both anti-CCP and AKA. There was no difference in clinical and biological features, including prevalence of RF, between anti-CCP positive and negative patients. The nine Sjögren patients with non-erosive arthritis, fulfilling ACR criteria for rheumatoid arthritis, were all CCP positive. Their response to disease modifying antirheumatic drugs could be different from classical rheumatoid patients. CONCLUSIONS Most patients with primary Sjögren's syndrome are negative for AKA and anti-CCP, but positive test results should not rule out this diagnosis. Anti-CCP positive patients, who may be prone to developing rheumatoid arthritis, require cautious clinical and radiographic follow up.

Abstract
BACKGROUND Anti-filaggrin antibodies (AFA) are among the most specific antibodies for rheumatoid arthritis, so procedures for their detection should be included in early biological diagnoses. AFA can be detected by indirect immunofluorescence (anti-keratin antibodies, AKA) or by new enzyme immunoassays (EIA). Their comparative performance needs to be established. OBJECTIVE To compare these technical procedures to optimise the serological diagnosis of rheumatoid arthritis. METHODS Results obtained using AKA and EIA were compared in 271 sera from 140 patients with rheumatoid arthritis at various stages, 98 patients with other autoimmune diseases, and 33 healthy subjects. EIA were successively undertaken with citrullinated linear filaggrin peptide (home made EIA) or cyclic citrullinated peptide (CCP2, commercial kits). Rheumatoid factor (RF) was assessed by EIA in all patients. RESULTS Anti-CCP2 kits showed the best sensitivity and specificity (65% and 96%, respectively). Among the 140 patients with rheumatoid arthritis, those with very recent disease (less than six months' duration, n = 21) were studied as a separate group. In this group, the sensitivity of anti-CCP2 kits decreased to approximately 50%. Nevertheless this assay remained the most accurate when compared with AKA or home made EIA using linear filaggrin peptides. The combination of anti-CCP2 and RF only slightly increased the sensitivity of the diagnosis of very early rheumatoid arthritis. CONCLUSIONS Kits using citrullinated cyclic peptides (CCP2) were more suitable than either AKA or EIA using linear filaggrin peptides for the diagnosis of early rheumatoid disease.

Abstract
UNLABELLED This study reports the first case of symptomatic placental transfer of cryoglobulins and discusses the potential pathogenic processes and the basic guidelines for neonatal management. A 32-y-old woman was affected by essential type I cryoglobulinaemia and displayed the cold-triggered cutaneous symptoms of the disease due to a monoclonal immunoglobulin G (IgG) cryoglobulin. She gave birth to healthy dizygotic twins who were placed in incubators immediately after birth and did not show any cutaneous or visceral lesion in the first 2 d. Cyanotic macules appeared on the hand and foot of one of the newborns when they were removed from the incubators. The same monoclonal IgG-lambda cryoglobulin was identified in the two newborns' cord blood and in the mother's serum. The skin lesions disappeared within 1 wk as both twins were transiently replaced in incubators. No recurrence of skin lesions was observed even at room temperature and, 6 mo later, both twins were healthy and their clinical examination was normal. CONCLUSION To the authors' knowledge, this is the first report of placental transfer of cryoglobulins and the first description of any neonatal effect. Neonates born to mothers suffering from IgG cryoglobulinaemia should be protected against cold to avoid precipitation of the pathogenic cryoglobulins, until spontaneous resolution.

OBJECTIVE To report on an uncommon association of agranulocytosis in primary Sjögren's syndrome (SS). METHODS The clinical, haematological, and immunological features of seven patients with primary SS associated with a chronic (>6 months) agranulocytosis, and the outcome of the patients, were analysed. RESULTS Patients were white women with an unexplained agranulocytosis. They all had non-erosive arthritis and three had a thrombocytopenia or Evan's syndrome. In three patients, transient or durable expansion of T lymphocytes was present in the peripheral blood or in the bone marrow, but evolved independently from neutrophil counts. There was no paroxysmal nocturnal haemoglobinuria clone or antibodies to neutrophil surface antigens. In vitro bone marrow culture was normal (four patients) or showed a decrease in colony forming unit-granulocyte monocyte (CFU-GM) and colony forming unit-erythroblast (CFU-E) (one patient). Serum levels of soluble Fas ligand (sFasL) were normal, and granulocyte-colony stimulating factor (G-CSF) concentrations were either normal or raised. One patient was treated with steroids associated with intravenous immunoglobulins and achieved a lasting response. Two other patients were treated with steroids and methotrexate, with poor efficacy. Short courses of subcutaneous G-CSF produced a transient and mild response in all three patients. Complete recovery of the neutrophils occurred temporarily during pregnancy in two patients. After a mean follow up of 34.8 months (range 6-139) all patients were alive and none developed serious infections. CONCLUSION A subset of patients with primary SS and non-destructive arthritis may develop a chronic but well tolerated agranulocytosis that is usually poorly responsive to steroids and oral methotrexate.

Abstract
OBJECTIVE To determine the prevalence of organ-specific and non-specific autoantibodies in HIV-infected patients. DESIGN A multicentric collaborative case-control study including 105 HIV patients and 100 sex- and age-matched HIV-negative healthy volunteers. METHODS Antinuclear, anti-ds DNA, anti-histone, anti-Sm, rheumatoid factor(IgM), anti-beta 2 glycoprotein 1, antineutrophil cytoplasmic, anti-LKM1, anti-LCA1, anti-gastric parietal cell, antiplatelet, anti-intermediate filament, anti-mitotic spindle apparatus, anti-Golgi, anti-ribosome and anti-thyroid autoantibodies were screened in six European laboratories. RESULTS Only IgG and IgM anticardiolipin, IgG antiplatelet, anti-smooth muscle and anti-thyroglobulin antibodies were statistically more frequent in HIV patients. There was no correlation with the numbers of CD4+ cells except in the case of anti-smooth muscle antibodies. We were unable to find specific autoantibodies such as anti-ds DNA, anti-Sm, AMA, anti-LKM1, anti-LCA1 or anti-beta 2 GP1 antibodies in these patients. CONCLUSIONS Our results indicate that the autoantibody profile of HIV infections is comparable to those of other chronic viral infections. HIV does not seem to be more autoimmunogenic than other viruses.

Abstract
Robusta coffee cherries collected before and during sun drying from two coffee farms in Thailand were examined for moulds producing ochratoxin A (OA). Aspergillus ochraceus was only detected in one sample, whereas Aspergillus carbonarius was isolated from 7 out of 14 samples. On gamma-irradiated coffee cherries, each of the six tested A. carbonarius strains produced OA. More than 4800 microg kg(-1) of toxin were detected under optimal conditions (25 degrees C, a(w) 0.99). OA production was strongly reduced (230 microg kg(-1)) at an a(w) of 0.94.

Abstract
PURPOSE Autoantibodies directed against the ribosomal P proteins, P0, P1 and P2 (anti-P), have been related to lupus-related psychosis and/or depression. The diagnostic value of antibodies directed against other ribosomal proteins or 28S RNA (anti-no-P) remains unknown. A multicenter study including ten centers belonging to the study group for autoimmune diseases (GEAI) was conducted in order to determine the diagnostic value of anti-P and anti-no-P antibodies in a large population of patients. METHODS The patients were selected on the basis of the presence of serum anti-ribosomal antibodies detected by indirect immunofluorescence (IF) on rat liver/kidney/stomach/pancreas sections and human HEp2 cells. The clinical course of all patients was studied using a predetermined survey. The specificity of anti-P antibodies were determined by Western blot. RESULTS Anti-ribosomal antibodies were found in 82 patients. Fifty-five of them had systemic lupus erythematosus and 27 had another disease. Only 54% of the anti-ribosomal antibodies detected by IF were anti-P and were found in 69% of the patients with systemic lupus erythematosus. Anti-no-P antibodies (46%) were preferably detected in patients who suffered from another disease (78%). In patients with systemic lupus erythematosus, neurological and psychiatric disorders were more frequent in the no-P group (47% vs. 16%, P < 0.01) than arthritis, which was found more frequently in the P group (78% vs. 53%, P < 0.05). CONCLUSION Anti P antibodies do not constitute a specific diagnostic marker of systemic lupus erythematosus, and lupus-related neuropsychiatric disorders would be preferably associated with the presence of anti no-P antibodies.

Abstract
The purpose of this study was to evaluate the relative sensitivity of neonatal and adult CD rats to manganese-induced neurotoxicity. Identical oral manganese chloride (MnCl(2)) doses (0, 25, or 50 mg kg(-1) body wt. day(-1)) were given to neonatal rats throughout lactation (i.e. from postnatal day (PND) 1 through 21) and to adult male rats for 21 consecutive days. The MnCl(2) doses administered to neonates were ca. 100-fold higher than those resulting from the consumption of an equivalent volume of rat's milk. Rats were assessed using similar behavioral and neurochemical evaluations. Several statistically significant changes occurred in Mn-exposed rats relative to control animals. Neonates given the high dose of MnCl(2) had reduced body weight gain. An increased pulse-elicited acoustic startle response amplitude was observed in neonates from both MnCl(2) treatment groups on PND 21. Increased striatal, hippocampal, hindbrain and cortical Mn concentrations were observed in all Mn-exposed neonates on PND 21. Increased hypothalamic and cerebellar Mn concentrations were also observed on PND 21 in neonates from the high-dose group only. Increased striatal, cerebellar and brain residue Mn concentrations were observed in adult rats from the high-dose group. Increased striatal dopamine and 3,4-dihydroxyphenylacetic acid levels were observed only in PND 21 neonates from the high-dose group. No treatment-related changes were observed in clinical signs, motor activity (assessed in neonates on PND 13, 17, 21 +/- 1 and in adults), passive avoidance (assessed in neonates on PND 20 +/- 1 and in adults) or neuropathology (assessed in PND 21 neonates only). The results of our experiment suggest that neonates may be at greater risk for Mn-induced neurotoxicity when compared to adults receiving similar high oral levels of Mn.

Abstract
BACKGROUND & AIMS Despite extensive investigations of portal vein thrombosis, no underlying cause is identifiable in up to 30% of patients. A recently described mutation of the prothrombin gene at nucleotide position 20210 is associated with history of venous thrombosis and was assessed in this study. METHODS We compared the frequency of factor II G20210A and factor V G1691A (factor V Leiden) mutations in 10 patients with idiopathic portal vein thrombosis, 10 patients with nonidiopathic portal vein thrombosis, 60 patients with deep vein thrombosis of the legs, and 42 control subjects. RESULTS The frequency of factor II G20210A mutation was increased in patients with idiopathic portal vein thrombosis (40.0%; confidence interval, 3.1%-76.9%) compared with controls (4.8%; confidence interval, 0%-11.5%) or patients with nonidiopathic portal vein thrombosis or deep vein thrombosis (P = 0.0001). In contrast, the frequency of the factor V G1691A mutation was similar in subjects with portal vein thrombosis and in controls but was increased in patients with deep vein thrombosis (P = 0.0001). CONCLUSIONS The factor II G20210A mutation is frequent in patients with idiopathic portal vein thrombosis and should therefore be assessed under this circumstance.

Abstract
Analysis of an abnormal C1q molecule of individuals of a Moroccan family by ultracentrifugation in sucrose gradients revealed a low molecular weight C1q (LMW-C1q). We investigated the molecular basis of this defect by sequencing all six exons of the three C1q genes. One point mutation in the codon for Gly at position 15 (GGT) of the B chain was found resulting in an amino acid substitution to Asp (GAT). The exchange not only leads to an interruption of the collagen-like motif Gly-X-Y, but also introduces one negatively charged residue per B chain which results in two additional charges per structural subunit (A-B, C-C, A-B). The mutation which has been identified by DNA-sequencing in the C1q-deficient younger brother of the propositus was confirmed by PCR-EcoRV-RFLP in the sister and the propositus himself. This mutation is very similar to a mutation previously described in another case of functional C1q deficiency where Gly at position 6 of the C chain was substituted by a large positively charged residue (Arg). Again, a LMW-C1q was demonstrated. These point mutations that lead to amino acid substitutions result in the production of a LMW-C1q where the formation of functionally active 11S C1q consisting of three structural subunits appears to be inhibited by the introduction of six additional charges, one per B or C chain, respectively, in the collagenous region of the molecule.

Abstract
The present case report describes a 27-year-old patient who presented with post-traumatic pleural effusion. Analysis of the pleural fluid showed hypereosinophilia (990 mm-3), a decreased level of total complement, and decreased levels of C3 and C4 fractions (less than 50% of normal serum levels), indicating a local consumption mechanism for complement. Complement serum levels (CH50, C3, C4) were normal. All other aetiologic possibilities were eliminated. This case suggests that the immunopathological mechanism of post-traumatic pleural effusion may involve activation of the classical pathway of complement and a recruitment of inflammatory cells such as eosinophils.

Abstract
The human ATFa proteins belong to the ATF/CREB family of transcription factors. We have previously shown that they mediate the transcriptional activation by the largest E1a protein and can heterodimerize with members of the Jun/Fos family. ATFa proteins have also been found tightly associated with JNK2, a stress-activated kinase. We now report on the structure of the ATFa gene, which mapped to chromosome 12 (band 12q13). Sequence analysis revealed that ATFa isoforms are generated by alternative splice donor site usage. A minimal promoter region of approximately 200 base pairs was identified that retained nearly full transcriptional activity. Binding sites for potential transcription factors were delineated within a GC-rich segment by DNase I footprinting. Expression studies revealed that ATFa accumulates in the nuclei of transfected cells, and the nuclear localization signal was defined next to the leucine zipper domain. As revealed by hybridization with mouse ATFa sequences, low levels of ATFa mRNAs were ubiquitously distributed in fetal or adult mice, with enhanced expression in particular tissues, like squamous epithelia and specific brain cell layers. The possible significance of coexpression of ATFa, ATF-2, and Jun at similar sites in the brain is discussed.
