Abstract
Spondyloarthropathy was observed in 25 (2.8%) of 895 preserved canid museum specimens and was catalogued by species. The associated skeletal alterations in canids are indistinguishable grossly and physiologically from those in humans with spondyloarthropathy of the reactive type. Rate of affliction was independent of captive or wild-caught status or gender. In canids, spondyloarthropathy was much more common than osteoarthritis (0.3%), which predominantly is limited to captive animals. Animal well-being may be enhanced by recognition of the condition and initiation of specific treatment.

Abstract
Medicinal products of biological origin still carry a specific iatrogenic risk, mainly because of their starting material, mode of preparation and variability. Careful postmarketing surveillance systems are therefore necessary. To assess the long-term safety of haemophilia treatment with plasma-derived and recombinant clotting factor products, a cohort study was set up in France in 1994. Participants were patients with haemophilia A and B, with or without previous clotting factor therapy. Clinical events, treatments, biological data and adverse events were recorded on standard forms. Blood samples were separated into serum, plasma and peripheral blood mononuclear cells, frozen, and banked in a central laboratory. The same data and samples were collected at yearly follow-up visits. As of December 1999, 1234 haemophiliacs were enrolled in 39 haemophilia centres. At enrollment, 50.2% of patients were under 15 years of age, and the cumulative number of days of exposure to the product was below 50 in 35.1% of cases. The median duration of follow-up was 26.9 months, with a total of 2729 patient-years (135,947 days of exposure and 211 million units of factor VIII or IX). To date, only 17 patients were lost to follow-up. The initial results show good compliance with this health-watch policy among patients and clinicians specializing in haemophilia. The regular follow-up data and centralized sample bank will serve to investigate rapidly any suspected outbreaks as soon as reliable biological tests become available in the future.

Abstract
Recognition of syphilis in Europe in the late 15th century and its prior absence suggest New World origin. Skeletal populations were examined from sites with documented Columbian contact in the Dominican Republic. Examination of 536 skeletal remains revealed periosteal reaction characteristic of treponemal disease in 6%-14% of the afflicted population. Findings were identical to that previously noted in confirmed syphilis-affected populations and distinctive from those associated with yaws and bejel: it was a low population frequency phenomenon, affecting an average of 1.7-2.6 bone groups, often asymmetric and sparing hands and feet, but associated with significant tibial remodeling. While findings diagnostic of syphilis have been reported in the New World, actual demonstration of syphilis in areas where Columbus actually had contact was missing, until now. The evidence is consistent with this site as the point of initial contact of syphilis and of its subsequent spread from the New World to the Old.

Abstract
Assessment of laboratory values is an important function of nursing practice. Rheumatologic laboratory assessment, in particular, can be complex because few findings are actually pathognomonic. This article provides a perspective on an interpretive approach to laboratory assessment of rheumatologic disease. In conjunction with the patient's clinical status, these values can provide helpful information for monitoring or predicting the course of disease.

Abstract
Inhibitors against von Willebrand factor (vWF) developed in two unrelated multitransfused patients (patients 1 and 2) with severe (type 3) von Willebrand disease (vWD) were analyzed. Both inhibitors were identified as antibodies of the IgG class by ELISA using immobilized purified vWF and either serum or purified Ig from the patients. Typing, mapping and functional studies of both antibodies revealed significantly distinct properties. Patient 1 antibody contained all subclasses of IgG (1, 2, 3 and 4) whereas antibody from patient 2 was a mixture of only IgG1 and 4. By ELISA using a series of immobilized purified proteolytic fragments of vWF, patient 1 antibody mainly bound to fragment SpIII and, to a lower extent, to fragments SpII and SpI; it poorly bound to P34 and the 39/34 kDa fragment. In contrast, patient 2 antibody only bound to fragments corresponding to the N-terminal portion of vWF but failed to bind to SpII. Functional studies were performed by testing the capacity of each antibody to inhibit vWF binding to its various ligands. Both antibodies blocked vWF binding to Factor VIII (FVIII), fibrillar type III collagen, bitiscetin and the subsequent induced binding to GPIb. Patient 1 antibody also blocked vWF binding to platelet GPIb when induced by ristocetin. However it failed to block vWF binding to GPIb when induced by botrocetin as well as the binding of botrocetin itself to vWF. Our data thus suggest that this inhibitor does not recognize the GPIb-binding site on vWF but the sites of vWF involved in its interaction with ristocetin. In contrast, we observed that patient 2 antibody blocked vWF binding to platelet GPIb induced by either agonist as well as vWF binding to botrocetin. Finally, the effect of the antibodies was tested on vWF binding to GPIIb/IIIa. As expected from the mapping experiments, only IgG from patient 1 blocked the interaction while IgG from patient 2 had no effect. In conclusion, we have shown that two multitransfused patients with type 3 vWD have developed alloantibodies with similar properties to those of polyclonal antibodies but with distinct effects on the functions of vWF.

Abstract
Fifteen previously untreated patients (Pups) with severe haemophilia B (factor IX activity < or = 2 U/dl) only treated with one brand of plasma-derived high purity factor IX concentrate (FIX LFB) were studied. Age at first injection varied from 1 to 137 months and follow-up since this first injection from 21 to 86 months (median: 35). Cumulative exposure days (CED) were from 4 to over 100 (median: 26). Among these 15 Pups only one developed an inhibitor. Mutation analysis performed in all patients showed total gene deletion in the patient with inhibitor, partial gene deletion in another one, and missense mutations in 9 families. Mutation was not found in one patient. Actually, according to the data already published, only two patients were at high risk for inhibitor development in our population. Our study, although rather small, confirms the previously reported low incidence of inhibitors in haemophilia B. Large studies on incidence of FIX inhibitors are indeed difficult to perform, due to both the overall small number of severe haemophilia B patients and the low incidence of FIX inhibitors. Consequently, the impact of bias, such as prevalence of different types of gene defects in a given population, is major. Therefore, any study, dealing with incidence of FIX inhibitors in severe haemophilia B should report, for each patient, the type of gene defect.

Abstract
The occurrence of inhibitor in a hemophilic patient is the greatest therapeutic complication in 1999. The inhibitor incidence is higher in hemophilia A (20-30%) than in hemophilia B (3%). At the moment, the best management is immune tolerance induction. This consists in frequent infusion of antihemophilic factor (every day or every other day). The risk of inhibitor development is higher in a young child than in an adult. Consequently, a venous access device is essential for this treatment although not devoid of complications in the young boy. Moreover, the probability of inhibitor disappearance is higher in a child (recent inhibitor) than in an adult ("old" inhibitor).

Abstract
Fifty French previously untreated patients with severe hemophilia A (factor VIII < 1%), treated with only one brand of recombinant factor VIII (rFVIII), were evaluated for inhibitor development, assessment of risk factors and outcome of immune tolerance regimen. The median period on study was 32 months (range 9-74) since the first injection of rFVIII. Fourteen patients (28%) developed an inhibitor, four of whom (8%) with a high titer (> or = 10 BU). All inhibitor patients but one continued to receive rFVIII either for on-demand treatment or for immune tolerance regimen (ITR). Among these patients, inhibitor was transient in 2 (4%), became undetectable in 6 and was still present in 6. The prevalence of inhibitor was 12%. Presence of intron 22 inversion was found to be a risk factor for inhibitor development. Immune tolerance was difficult to achieve in our series despite a follow-up period of 16 to 30 months: immune tolerance was complete in only one out of the 3 patients undergoing low dose ITR and in one out of the 5 patients with high dose ITR.

Abstract
OBJECTIVE To characterize hypertrophic osteoarthropathy (HOA) in skeletons to allow its recognition in the archeologic record. METHODS Individuals diagnosed in life with diseases known to cause HOA were examined from the Hamman-Todd, Grant, and Terry human skeletal collections. The latter consist of 5142 individuals who died in the early part of this century. A "control" group was obtained by examination of 100 (consecutive, exclusive of HOA related disorders) additional individuals from the Terry Collection, which were accompanied by diagnoses not known to be associated with HOA. Sixty individuals documented with skeletal evidence of syphilis (from the Hamman-Todd Collection) and 73 individuals documented as having skeletal evidence of yaws (from the Ward Site, 4300 ybp) were examined as comparison treponemal disease-derived, periosteal reaction-afflicted populations. RESULTS In total, 319 individuals were identified with HOA. HOA was recognized as a disorder of distal diaphyseal or diffuse periosteal reaction. Proximally-limited disease virtually eliminates the diagnosis. CONCLUSION HOA is recognizable as a population phenomenon suggestive, when found in the archeologic record, of underlying chronic pulmonary disease.

Abstract
Von Willebrand disease is the most frequent congenital bleeding tendency (1%). The moderate form is the most common (around 80%). It must consistently be investigated prior to any surgery because of a real risk of bleeding during or after the procedure. Once the diagnosis is made, the indication of DDAVP has to be examined in order to make the best therapeutic choice in case of surgery or severe bleeding.

Abstract
Spondyloarthropathy was documented for the first time in 14 (3.7%) of 386 large cats, affecting eight species belonging to three genera. The limited distribution of joint erosions, associated with spine and sacroiliac joint pathology, was indistinguishable from that occurring in humans with spondyloarthropathy of the reactive type. This form of inflammatory arthritis is almost twice as common as osteoarthritis (for felids as a whole), and animal well-being may be enhanced by its recognition and by initiation of specific treatment.

Abstract
The present study discusses in detail the osteological changes associated with sickle cell anemia in children and their importance in differential diagnosis. Posterior calcaneal and specific articular surface disruptive metacarpal lesions are diagnostic for sickle cell anemia. Calvarial thickening, tibial and femoral cortical bone thickening, and bowing are of more limited utility in differential diagnosis. Granular osteoporosis, pelvic demineralization and rib broadening are nonspecific. Localized calvarial "ballooning," previously not described, may have diagnostic significance. Bone marrow hyperplastic response (porotic hyperostosis) in sickle cell anemia produces minimal radiologic changes contrasted with that observed in thalassemia and blood loss/hemolytic phenomenon. Two other issues, the osteological criteria for discriminating among the anemias and the purported relationship between porotic hyperostosis and iron deficiency anemia, are also discussed. There is sufficient information to properly diagnose the four major groups of anemias, and further, to establish that iron deficiency is only indirectly associated with porotic hyperostosis. The hyperproliferative bone marrow response (manifest as porotic hyperostosis) to blood loss or hemolysis exhausts iron stores, resulting in secondary iron deficiency.

Abstract
The controversy over the reliability of ectocranial suture status (open vs. closed) as an age estimation stimulated the pursuit of Meindl and Lovejoy's suggestion (Meindl and Lovejoy [1985] Am. J. Phys. Anthropol. 68:57-66) for large scale analysis. The extent of the sagittal suture closure was assessed in 3,636 skulls from the Hamann-Todd and Terry collections. The debate over whether cranial suture ossification represents a pathologic or an age-predictable pathologic process also stimulated a comparison with age and two stress markers, hyperostosis frontalis interna and tuberculosis. Sagittal suture closure was found to be age-independent and sexually biased. The wide confidence intervals (for age) appear to preclude meaningful application of suture status for age determination. No correlation was found with the tested biological stressors.

Abstract
In the present study, 1,869 skulls from the Hamann-Todd Collection were examined (macroscopically and by radiographs) for closure of the petroexoccipital articulation (jugular synchrondrosis). The results demonstrated the the petroexoccipital articulation underwent closure between 20 and 50 years of age in most human skulls evaluated. Approximately 7-10% of the human skulls underwent complete union of the petroexoccipital articulation before 20 years of age. In 5-9% of the population, the joint remained completely open. After 50 years of age, there was no increase in the frequency of individuals with incomplete closure. The frequency of "partial closure" was similar (4-8%) for all age groups (20-25, 30-35, 40-45, 50-55, 60-65, and 70+), excluding the 30-35 year old group (17.5%). The time interval necessary for closure to occur appeared to be very short. No significant differences in closure rates due to ethnic origin, gender, or laterality were noted. The utility of the pteroexoccipital articulation as an age estimator is discussed.

Abstract
Factor VIII or factor IX replacement is frequently impossible in inhibitor-developing hemophiliacs, because of the level of the inhibitor titer. Activated prothrombin complex concentrates are one of the available options to treat the bleeding episodes in such patients. However, the efficacy of these products and the associated thrombogenic risk, particularly in prolonged administration such as employed during surgeries, are important concerns for hemophilia care providers. We performed a multicenter retrospective study to evaluate the use of FEIBA (Factor Eight Bypassing Activity) in France, and data is presented on 433 bleeding episodes, including surgical procedures, concerning 60 patients from 15 hemophilia centers. The efficacy was judged as good or excellent in 352 episodes (81.3%), poor in 73 episodes (16.9%) and non-existent in 8 episodes (1.8%). Minor and major surgical procedures were successfully performed using FEIBA as a second-line therapy after human or porcine factor VIII, and in some occasions FEIBA was utilized as the only substitution product. The tolerance was assessed as good in 428 episodes (98.8%), but in 5 cases adverse effects were reported. Only 3 patients out of 52 regularly evaluated (5.8%) were HIV-seropositive, and for two of them the seroconversion occurred prior to the first use of FEIBA. In contrast, 80.4% of the patients were HCV-seropositive. An anamnestic response after the administration of FEIBA was noted in 31.5% of cases. This study points out the main features of the use of FEIBA in France, and particularly the low HIV seroprevalence in the patients treated. The good efficacy and the excellent tolerance still confer to this product a place to consider in the therapeutic options for the treatment of inhibitor-developing hemophiliacs or in acquired hemophilia.

Abstract
Recognition of disease in the archeologic record is facilitated by characterization of the skeletal impact of documented (in life) disease. The present study describes the osteological manifestations of leukemia as identified in the skeletons of two individuals diagnosed during life: a 3-year-old black girl with acute lymphocytic leukemia and a 60-year-old white male with acute myelogenous leukemia in the Hamann-Todd collection. Contrasting with the lack of specificity of radiologic findings, macroscopic skeletal changes appear sufficiently specific to allow distinguishing leukemia from other forms of cancer. While leukemia appears confidently diagnosable, distinguishing among the varieties (e.g., myelogenous and lymphocytic) does not appear possible at this time. Skeletal findings in leukemia are presented in tabular form to facilitate their application to future diagnosis of the disease in the archaeological record.

Abstract
The opportunity to examine the defleshed skeleton of an individual diagnosed in life (Hamann-Todd collection, individual 2036) afforded a unique opportunity to demonstrate the bone damage characteristic of at least one form of juvenile rheumatoid arthritis (JRA). Characteristics helpful for recognition of JRA in archaeological material include peripheral articular marginal and subchondral erosions, axial (e.g., zygapophyseal or sacroiliac) joint erosions, fusion of axial (cervical zygapophyseal) and/or peripheral joints, premature epiphyseal closure and/or ballooned epiphyses, growth retardation with underdeveloped (short and overtubulated) long bones, short mandibular rami with underdeveloped condyles and concomitant micrognathia, and demineralization (osteopenia). Distinguishing between JRA and juvenile spondyloarthropathy, however, is not always possible, as illustrated by this case.

Abstract
The distribution and kinetics of hepatitis C virus (HCV) genotypes and the prevalence of mixed infections were studied in a group of 45 French patients with haemophilia A or B or von Willebrand's disease, 21 of them being anti-human immunodeficiency virus (HIV) positive; genotyping was carried out by three methods based on the core, 5' untranslated region (5'UTR), and the detection of type-specific NS4 antibodies. Genotyping of the 5'UTR revealed genotypes 1a (n = 10), 1b (n = 13), 2a (n = 3), 2b (n = 4), 2NC (n = 3), 3a (n = 10), and two mixed infections (1a + 1b and 3a + 2). Five of 33 patients showed a change from one HCV genotype to another. The core genotyping assay showed 8 of 45 mixed infections: 6/8 1a + 1b and 2/8 3a + 2. Sequencing of core polymerase chain reaction (PCR) products showed that mixed infection 1a + 1b could be explained by nonspecific annealing of the 1b primer to type 1a sequence. By designing new primers whose sequence was more specific to HCV types 1a and 1b, we could confirm 1a + 1b mixed infection in only one of six cases. Serotyping assay showed for 17 of 21 anti-HIV negative patients a concordance with the 5'UTR genotype; however, only 6 of 19 anti-HIV positive patients showed detectable serological reactivity. In summary, we have observed a similar HCV genotype distribution between our haemophilic group and the French anti-HCV positive patients. The study demonstrates the difficulties of assessing with the presently available genotyping and serotyping assays the real prevalence of mixed infections in multiply transfused patients.
