Abstract
BACKGROUND The goal of the study was to provide relevant data about the location and prevalence of the occipital artery-vertebral artery (OA-VA) anastomosis in patients without visible occlusive disease, as well as to thoroughly discuss the clinical significance of these anastomotic channels. Furthermore, the morphometric properties of the OA and its branches were also analysed. MATERIALS AND METHODS A retrospective study was carried out to indicate anatomical variations, their prevalence, and morphometrical data on the OA and its branches. The study was performed on 55 randomly selected computed tomography angiographies (CTA) of the head and neck region. Each CTA result was analysed bilaterally. Thus, 110 results were originally assessed. RESULTS The OA median maximal diameter was demonstrated at 4.85 mm (lower quartile [LQ]: 4.11; upper quartile [UQ]: 5.53) and the median maximal diameter of VA at 3.60 mm (LQ: 2.79; UQ: 4.38). The distances between OA and its branches were also measured giving a median result of 21.73, 30.29, 60.84, 34.88, 18.02, 55.16 mm for the lower and upper sternocleidomastoid branch, meningeal branch, mastoid branch, and descending branch, respectively. The median distance between OA and its first anastomosis was set to be 51.15 mm (LQ: 37.20; UQ: 60.10). Moreover, a set of additional measurements was carried out in order to create a three-dimensional anatomical heat-map of the occurrence of the OA-VA anastomosis. CONCLUSIONS Knowledge about the anatomy of the OA-VA anastomosis might be of immense importance to avoid potentially fatal complications during embolisation of the OA and its branches.

Abstract
The independent prognostic impact of specific dysplastic features in acute myeloid leukemia (AML) remains controversial and may vary between genomic subtypes. We apply a machine learning framework to dissect the relative contribution of centrally reviewed dysplastic features and oncogenetics in 190 patients with de novo AML treated in ALFA clinical trials. One hundred and thirty-five (71%) patients achieved complete response after the first induction course (CR). Dysgranulopoiesis, dyserythropoiesis and dysmegakaryopoiesis were assessable in 84%, 83% and 63% patients, respectively. Multi-lineage dysplasia was present in 27% of assessable patients. Micromegakaryocytes (q = 0.01), hypolobulated megakaryocytes (q = 0.08) and hyposegmented granulocytes (q = 0.08) were associated with higher ELN-2017 risk. Using a supervised learning algorithm, the relative importance of morphological variables (34%) for the prediction of CR was higher than demographic (5%), clinical (2%), cytogenetic (25%), molecular (29%), and treatment (5%) variables. Though dysplasias had limited predictive impact on survival, a multivariate logistic regression identified the presence of hypolobulated megakaryocytes (p = 0.014) and micromegakaryocytes (p = 0.035) as predicting lower CR rates, independently of monosomy 7 (p = 0.013), TP53 (p = 0.004), and NPM1 mutations (p = 0.025). Assessment of these specific dysmegakarypoiesis traits, for which we identify a transcriptomic signature, may thus guide treatment allocation in AML.

Abstract
The reaction of Hector Battifora mesothelial epitope-1 (HBME-1) antibody with scattered pronormoblasts in normal bone marrow core biopsy specimens has been reported. This study evaluated the immunohistochemical profile of HBME-1 in a panel of 52 normal, dyserythropoietic and neoplastic marrow samples. We compared the staining property of HBME-1 with that of the commonly used erythroid marker, glycophorin A (CD235a) and in each case, we semi-quantitatively evaluated the HBME-1/CD235a-positive cells ratio. In normal samples, HBME-1 labelled scattered immature erythroid precursors. In dyserythropoietic specimens, HBME-1 stained nucleated erythroid precursors in varying degrees, from pronormoblast through normoblast stages, with the highest intensity in immature forms. Overall, the cellular background of non-erythroid progenitors, erythrocytes and neoplastic cells did not react with HBME-1, except in leukaemia cases with myelodysplasia-related changes. Our study shows that HBME-1 is a useful marker to identify immature erythroid precursors and that an HBME-1/CD235a-positive cells ratio ≥10% is associated with dyserythropoiesis.

Abstract
Blastic plasmacytoid dendritic cell neoplasm is an aggressive malignancy derived from plasmacytoid dendritic cells. There is currently no accepted standard of care for treating this neoplasm, and therapeutic strategies have never been prospectively evaluated. Since blastic plasmacytoid dendritic cell neoplasm cells express high levels of interleukin-3 receptor α chain (IL3-Rα or CD123), antitumor effects of the interleukin-3 receptor-targeted drug SL-401 against blastic plasmacytoid dendritic cell neoplasm were evaluated in vitro and in vivo. The cytotoxicity of SL-401 was assessed in patient-derived blastic plasmacytoid dendritic cell neoplasm cell lines (CAL-1 and GEN2.2) and in primary blastic plasmacytoid dendritic cell neoplasm cells isolated from 12 patients using flow cytometry and an in vitro cytotoxicity assay. The cytotoxic effects of SL-401 were compared to those of several relevant cytotoxic agents. SL-401 exhibited a robust cytotoxicity against blastic plasmacytoid dendritic cell neoplasm cells in a dose-dependent manner. Additionally, the cytotoxic effects of SL-401 were observed at substantially lower concentrations than those achieved in clinical trials to date. Survival of mice inoculated with a blastic plasmacytoid dendritic cell neoplasm cell line and treated with a single cycle of SL-401 was significantly longer than that of untreated controls (median survival, 58 versus 17 days, P<0.001). These findings indicate that blastic plasmacytoid dendritic cell neoplasm cells are highly sensitive to SL-401, and support further evaluation of SL-401 in patients suffering from blastic plasmacytoid dendritic cell neoplasm.

Abstract
INTRODUCTION The presence of schistocytes on the peripheral blood film during disseminated intravascular coagulation (DIC) remains controversial. METHODS We examined schistocytes count on blood films from 35 DIC patients and checked morphological anomalies of all RBCs. RESULTS Thirty of 35 patients presented with schistocytes and 22 with acanthocytes, which was the commonest shape anomaly. Mean percentage ± standard deviation was 0.33 ± 0.38%, median value was 0.1%, and range was 0-1.4%. The patients with schistocytes ≥ 1% had circumstances frequently associated with increased schistocytes count (promyelocytic leukaemia, pregnancy, severe infection). DISCUSSION Schistocytes were thus frequently observed in DIC patients, usually with low percentage, within or close to the reference range (<0.5%). Schistocytes measurement is not a clue test for the initial diagnosis of DIC, but might be of clinical value to suggest an associated or underlying thrombotic microangiopathy if ≥ 1%.

Abstract
Background Chloroquine (CQ) was the main malaria therapy worldwide from the 1940s until the 1990s. Following the emergence of CQ-resistant Plasmodium falciparum, most African countries discontinued the use of CQ, and now promote artemisinin-based combination therapy as the first-line treatment. This change was generally initiated during the last decade in West and Central Africa. The aim of this study is to describe the changes in CQ susceptibility in this African region, using travellers returning from this region as a sentinel system. Methods The study was conducted by the Malaria National Reference Centre, France. The database collated the pfcrtK76T molecular marker for CQ susceptibility and the in vitro response to CQ of parasites from travellers’ isolates returning from Senegal, Mali, Ivory Coast or Cameroon. As a proxy of drug pressure, data regarding CQ intake in febrile children were collated for the study period. Logistic regression models were used to detect trends in the proportions of CQ resistant isolates. Results A total of 2874 parasite isolates were genotyped between 2000–2011. The prevalence of the pfcrt76T mutant genotype significantly decreased for Senegal (from 78% to 47%), Ivory Coast (from 63% to 37%), Cameroon (from 90% to 59%) and remained stable for Mali. The geometric mean of the 50% inhibitory concentration (IC50) of CQ in vitro susceptibility and the proportion of resistant isolates (defining resistance as an IC50 value > 100 nM) significantly decreased for Senegal (from 86 nM (59%) to 39 nM (25%)), Mali (from 84 nM (50%) to 51 nM (31%)), Ivory Coast (from 75 nM (59%) to 29 nM (16%)) and Cameroon (from 181 nM (75%) to 51 nM (37%)). Both analyses (molecular and in vitro susceptibility) were performed for the 2004–2011 period, after the four countries had officially discontinued CQ and showed an accelerated decline of the resistant isolates for the four countries. Meanwhile, CQ use among children significantly deceased in this region (fixed effects slope = −0.3, p < 10-3). Conclusions An increase in CQ susceptibility following official withdrawal of the drug was observed in travellers returning from West and Central African countries. The same trends were observed for molecular and in vitro analysis between 2004-2011and they correlated to the decrease of the drug pressure.

Abstract
Feto-maternal alloimmune thrombocytopenia (FMAIT) results from the maternal production of antibodies against fetal platelets with incompatible antigens inherited from the father. We present a case where this condition was diagnosed prenatally without previously affected siblings. The severe fetal thrombocytopenia was due to anti-HLA-5b maternal alloantibodies. This was treated successfully by intravenous immunoglobulins. Our case reflects that FMAIT due to anti-HPA-5b may be severe and may be corrected successfully with intravenous immunoglogulins.

Abstract
Binucleated lymphocytes on blood smear are known in PPBL characterized by stable and polyclonal lymphocytosis, polyclonal increase of serum IgM, HLA DR7 and strong correlation with additional i(3q) and premature chromosome condensation. In this disorder some reports of clonal Ig rearrangement suggest a follow up of these patients with immunological and genetic studies. Binucleated lymphocytes are rarely described in other clonal B-CLPD as B-CLL or marginal zone B-cell lymphoma (MZL). Chromosome 3 abnormality is never described in B-CLL but trisomy 3 represents the most consistent abnormality characterizing the MZL. We report in a man without previous medical history an unusual B-CLPD with monoclonal lymphocytosis CD5-, characteristic cytology (particularly binucleated lymphocytes) and chromosomic abnormality as dicentric chromosome 3 never previously described in B-CLPD. In this case lymphocytosis is persistent and stable over 24 months, cytologic immunologic and chromosomic abnormalities are unchanged. We discuss the nosologic place of this atypical B-CLPD closely related to PPBL and MZL with at the moment, after 24 months, a quiet evolution that imply nevertheless a careful follow up with regular cytologic, immunological and genetic studies to clarify the issue.

Abstract
Four airport malaria cases have been observed in the vicinity of the Roissy-Charles-de-Gaulle International Airport, Paris, France. These cases were geographically very close to each other and clustered in a short period of time during the summer of 1999. The phenotype and genotype of the Plasmodium falciparum isolates obtained from these patients were determined in order to know whether a single mosquito could have infected more than one subject. The genomic characterisation of isolates was performed using the polymorphic markers merozoite surface protein 1 (Msp 1) and merozoite surface protein 2 (Msp 2) genes, the kappa and omega repeats domains of cg2 and the dihydrofolate reductase (DHFR) genotypes. Results showed identical genotypes for isolates 1, 2 and 4 whereas the genotype of isolate 3 differed at one locus. The molecular analysis was consistent with the hypothesis that all patients could have been bitten by the same mosquito and that patient 3, may have received a different clone and an additional species. In vitro susceptibility data did not confirm or rule out this hypothesis because isolates had the same profile of susceptibility to the tested drugs.

Abstract
Between April and October 1997, 21 children of 4 days to 13 years old were admitted to the Pedatric Unit of Aulnay Sous Bois's Hospital for viral meningitidis. The number of white blood cells in the cerebrospinal fluid (CSF) was between 1 and 612 cells/mm3, with, on an average, 56% of segmented cells, 34% lymphocytes and 34% monocytes. Proteins and glucose of CSF were standard. One CSF was normal. Viral meningitidis was confirmed by viral culture of CSF onto MRC5. Enterovirus were identified by direct immunofluorescence (Monoclonal Mouse Anti-Enterovirus, Dako). Serotyping (Enterovirus antisera, Eurobio, Trousses 4) identified an echovirus 30 in all cases. A highly conserved 154 bp sequence at the 5'non-coding region was studied by reverse transcription-polymerase chain reaction (RT-PCR) followed by single-strand conformation polymorphism (SSCP) (GenPhor, Pharmacia) analysis. Two dominant SSCP patterns were observed: the first contained 4/21 strains and the other 10/21 strains. The SSCP patterns of the 7 other strains were different. These results show that 2 echovirus 30 dominant clones were responsible of viral meningitidis admitted to the Pediatric Unit of Aulnay Sous Bois's hospital, between april and october 1997. The PCR-SSCP of the 5'non-coding region of echovirus 30 is a convenient, simple, reproducible epidemiologic method and it's easily applicable in a general hospital.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of cordocentesis on fetomaternal hemorrhage (FMH). METHODS One hundred and three diagnostic cordocenteses, without any other associated procedure, were performed at 23-40 weeks' gestation. FMH was detected using the Kleihauer-Betke staining of maternal blood taken immediately before and after cordocentesis. RESULTS Significant FMH occurred after 40 (38.8%) of the 103 procedures. An increased risk of fetal bleeding was associated with both an anterior placenta (odds ratio (OR) 5.89; 95% confidence interval (CI) 2.27-15.3; p < 0. 001) and a transplacental cordocentesis (OR 37.0; 95% CI 2.15-636; p < 0.001). The volume of FMH was greater after cordocentesis with an anterior placenta (90th percentile 6.20 ml) than after cordocentesis with a lateral (90th percentile 4.58 ml) or posterior placenta (90th percentile 1.35 ml) (p < 0.001). After fetal blood sampling, significant FMH occurred more frequently with a procedure duration of 3 min or more (OR 4.45; 95% CI 1.70-11.7; p = 0.002) and with two or more needle insertions (OR 4.65; 95% CI 1.80-12.1; p = 0.001). CONCLUSION FMH following cordocentesis may be related to placental injuries. This event is influenced by placental location, procedure duration and the number of needle insertions.

Abstract
We report a new case of idiopathic hypereosinophilic syndrome with multivisceral digestive failure. After an erroneous diagnosis of pancreatic cancer, the pathological examination of pancreaticoduodenectomy specimen demonstrated pancreatic fibrosis with eosinophilic infiltration without gastritis or duodenitis. The diagnosis of idiopathic hypereosinophilic syndrome was made three months later upon the classical criteria: a) blood eosinophilia of 1.5 G/L or more, persisting for more than 6 months; b) lack of evidence for any other recognised cause of eosinophilia: c) multiple organ systemic involvement: rheumatologic, cutaneous and digestive (pancreatitis, ascites and diarrhoea): d) previous history of allergic disease and increased plasmatic IgE levels; e) absence of leukemic markers. This case emphasises the difficulty in classifying eosinophilic infiltration of the gut and the possibility of transitional forms between eosinophilic gastro-enteritis and idiopathic hypereosinophilic syndrome. We argue that in case of eosinophilic infiltration of the gut, systematic research of multiple organ systemic involvement is mandatory.

Abstract
This study evaluates the effect of funisocentesis on umbilical artery, fetal cerebral artery, and aortic circulation. The pulsatility index in the umbilical artery, fetal middle cerebral artery, and descending aorta was measured by pulsed Doppler ultrasonography before and after 41 diagnostic funisocenteses. Percutaneous umbilical artery blood sampling was associated with a significant decrease in umbilical artery pulsatility index (mean -0.132, standard deviation 0.259, P = 0.002) and in middle cerebral artery pulsatility index (mean -0.143, standard deviation 0.260, P = 0.001). The decline in resistance to flow of the umbilical artery (r = 0.340, P = 0.029) and middle cerebral artery (r = 0.457, P = 0.002) was correlated with gestational age at sampling. These findings suggest that alterations in the waveforms from both the umbilical and the fetal cerebral circulations can be induced by fetal blood sampling.

Abstract
A retrospective study on 202 consecutive patients with HIV infection was reviewed. A particular syndrome with blood CD8 lymphocytosis > 1 500/mm3, associated with a diffuse lymphocytic infiltrate histologically proved in the tissue of different organs was present in five patients. Clinical findings were variable, depending on the location of visceral infiltrate by activated, polyclonal lymphocytes of CD8 phenotype: interstitial pneumonia (n = 3), parotid gland enlargement with sicca syndrome (n = 2), pseudo-tumoral splenomegaly (n = 1), peripheral neuropathy (n = 1), superficial generalized lymphadenopathy (n = 5). This syndrome occurred early during HIV infection. All patients had a blood CD4 lymphocyte count > 200/mm3. This disorder is a host immune response, sometimes associated with the presence of some HLA antigens: HLA-DR5 or HLA A1 B8 DR3. Whether this immune response is specific or not, whether outcome of HIV infection depends on hyper CD8 lymphocytosis remains to be proved.

Abstract
We report a case of acute leukaemia occurring early in the course of IgA multiple myeloma. Ultrastructural studies, immunophenotyping and karyotyping were required to identify the origin and clonality of the leukaemic cells. Although ultrastructural examination of the blast cells revealed both monocytoid and plasma cell features, all cells expressed the CD 38 antigen and intracytoplasmic kappa light chains, while karyotyping revealed a clone with numerous abnormalities, leading to the diagnosis of clonal plasma cell disease. The occurrence of leukaemia in multiple myeloma is discussed.

Abstract
During a ten month period (march-december 1989), all streptococcal strains isolated from clinical specimens sent to our laboratory were routinely tested for high-level resistance to aminoglycosides. High-level resistance was detected in 16 out of 475 streptococci: streptomycin (two strains), kanamycin (four strains), streptomycin and kanamycin (ten strains).

Abstract
The cutaneous leishmaniasis is rampant in an endemo -epidemic way in the region of Thiès, Senegal. At the occasion of an epidemic observed between 1975 and 1978, the ecological study of the focus of Keur Moussa , led by Dedet and al., permitted to discover, for the first time in West Africa, the structure of a cutaneous leishmaniasis focus. The most important part of the present laboratory work consists in the observation of that wild anthropozoonosis due to Leishmania tropica major, having as vector Phlebotomus duboscqi and the rodents Mastomys erythroleucus , Tatera gambiana and Arvicanthis niloticus as reservoir. The close study of the reservoir populations and of the vectors should enable us to avoid a new epidemic outburst.
