- Abstract
Background: To conduct a morphological and morphometric analysis of the sacral hiatus (SH) using lumbosacral spine CT scans and to evaluate its clinical relevance in caudal epidural analgesia (CEA)., Materials and Methods: This retrospective study analyzed 77 lumbosacral spine CT scans from a diverse patient population. The shape of the SH was classified into common types: inverted U, inverted V, irregular, and bilobed. Morphometric measurements included the length, width, and depth at the apex of the SH. The apex level of the SH was also determined in relation to the sacral vertebrae, and statistical analysis was performed to identify any correlation between the apex level and the morphometric dimensions., Results: The most frequent SH shape was inverted U (68.83%), followed by inverted V (20.77%), irregular (9%), and a single instance of a bilobed shape (1.29%). The apex of the SH was most commonly located at the level of the S4 vertebra (75.32%), followed by the S3 vertebra (20.77%), S5 in two (2.59) and S2 in one (1.29%). No significant correlation was found between the level of the apex and the length, width, or depth of the SH. These findings indicate a high degree of anatomical variability in the SH, independent of the apex level., Conclusions: The anatomical variability of the SH, as observed in this study, underscores the need for individualized assessment during CEA. The lack of correlation between the apex level and the morphometric dimensions of the SH highlights the importance of imaging modalities such as ultrasound or fluoroscopy to ensure precise localization and effective analgesia administration. These insights can improve clinical outcomes by enhancing the accuracy and safety of caudal epidural procedures.

- Abstract
Alcohol consumption is linked to over 200 diseases and injuries. It is also classified as a risk factor for several types of neoplasms as well as infectious diseases (i.e., HIV and tuberculosis). In 2019, among people aged 25 to 49, alcohol use was the leading risk factor for attributable burden of disease. There are many factors that affect alcohol drinking patterns such as social and economic status, social norms, cultural customs, availability of alcohol, etc. Stress also plays a significant role in the process of developing alcohol addiction. The aim of our study was to examine health patterns and stress levels among patients undergoing alcohol addiction treatment. The study sample consisted of 104 patients who were treated in a hospital ward due to alcohol dependence. Three standardized questionnaire tools were used to measure the sense of coherence and the level of stress among those patients. The main results suggest that the level of perceived stress correlated negatively with all dimensions of sense of coherence and all indicators of health behaviors, however, age was positively correlated with positive mental attitude, proper eating habits, and health behaviors. In conclusion, it is worth noting that developing patterns for positive health behaviors will make it possible to avoid alcohol dependence or reinforce the treatment results if alcohol dependence syndrome occurs.

- Abstract
(1) Background: Acceptance of illness is a process in which a person with an illness accepts its presence and treats it as an integral part of their life. With regard to alcoholism, acceptance of illness is one of the important elements of the healing process. (2) Methods: The study group consisted of 104 residents in an addiction treatment ward. Questionnaires SOC-29, AIS and PSS-10 were used to check levels of coherence, stress and acceptance of illness. The analysis was based on regression analysis. Patient age was analysed as a moderator of correlations between perceived indicators. Moderation analysis was based on the simple moderation model. (3) Results: The level of perceived stress correlated negatively with all areas of the sense of coherence and with acceptance of illness. All areas of the sense of coherence correlated with acceptance of illness positively. (4) Conclusions: The acceptance of illness by the patient is a factor that can be motivating for further treatment, through a positive approach to illness and strengthening the sense of control in experiencing it. The combination of strengthening behavioural, cognitive and motivational resources can be used in the treatment of people experiencing the challenges of addiction to alcohol.

- Abstract
The objective of this meta-analysis was to present transparent data on the morphology of the pituitary gland (PG) using the available data in the literature. The main online medical databases, such as PubMed, Embase, Scopus, and Web of Science, were searched to gather all relevant studies regarding PG morphology. The mean overall volume of the PG was found to be 597.23 mm
3 (SE = 28.81). The mean overall height of the PG was established to be 5.64 mm (SE = 0.11). The mean overall length of the PG was found to be 9.98 mm (SE = 0.26). In the present study, the PG's overall morphology and morphometric features were analyzed. Our results showed that, on average, females from Asia have the highest volume of PG (706.69 mm3 ), and males from Europe have the lowest (456.42 mm3 ). These values are crucial to be aware of because they represent the normal average properties of the PG, which may be used as reference points when trying to diagnose potential pathologies of this gland. Furthermore, the present study's results prove how the PG's size decreases with age. The results of the present study may be helpful for physicians, especially surgeons, performing procedures on the PG.- Published

- 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
Introduction: Alcohol dependence is one of the world's major health challenges. The salutogenic concept of health developed by Antonovsky focuses on the search for resources and factors supporting health. Its basic concept of the sense of coherence (SOC) focuses on strengthening the global orientation of the patient, and creating permanent internal resources that translate into the improvement of pro-health behavior, including the fight against alcoholism., Objective: The objective of this study was to determine the correlation between individual factors and the SOC as well as the influence of the SOC concept on pro-health behavior of people addicted to alcohol., Materials and Methods: The study group consisted of 110 men undergoing treatment in an addiction treatment ward. To check the level of the SOC, two standardized questionnaires, Antonovsky's "SOC-29 Life Orientation Questionnaire" and Juczyński's "Health Behaviour Inventory", were used. The correlation coefficient between the sociodemographic variables was checked using the Pearson's r test., Results: A positive correlation was found with the intensity of pro-health behaviors for three sociodemographic variables. In people aged 43-65 (r = 0.299; p = 0.030), people with primary/vocational education (r = 0.276; p = 0.015), and respondents living in rural areas (r = 0.303; p = 0.028) a greater SOC was associated with pro-health behaviors., Conclusions: Individuals addicted to alcohol are characterized by a low SOC and a low level of pro-health behaviors. Strengthening the internal level of the SOC can constitute an element of addiction therapy when introducing health education to prepare the patient for independent life in sobriety.

- 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., (© 2021.

- Abstract
Introduction: Carpal tunnel syndrome (CTS) is a condition caused by chronic compression of the median nerve. The diagnosis is made mainly on the basis of clinical image and confirmed with electrodiagnostic testing (electromyography and nerve conduction study); however, these methods do not always aid in reaching the diagnosis of CTS. Moreover, they are invasive examinations, unpleasant for the patient and have to be performed by a qualified physician., Aim: An evaluation of the usefulness of dynamic thermography in the diagnosis of CTS., Material and Methods: Forty patients were included in the study group. CTS was diagnosed based on clinical examination and electromyography. Forty healthy volunteers were included in the control group. Each of the participants was examined thrice with dynamic thermography. The patient's hands were first cooled down and then a thermal camera measured their return to normal temperature. The measurement was repeated on the dorsal and volar aspects of each hand., Results: The results obtained in the study show that a relief of symptoms after carpal tunnel release does not correlate with thermal image. Moreover, the return to normal hand temperature was faster in the control group. In patients with unilateral CTS, no difference was observed in thermographic images of the affected and healthy hands., Conclusions: Dynamic thermography can be useful in confirming CTS diagnosis.Dynamic thermography does not allow for objective assessment of patient's complaints in the postoperative period.This method has currently limited clinical application. Due to complexity, it presently serves mainly scientific purposes., Competing Interests: Conflict of interest: The authors declare no conflicts of interest. This study has not been presented previously. This study was financed by authors’ own resources, (© 2021 Piotr Bargiel et al., published by De Gruyter.)

- Abstract
The purpose of the research was to define the frequency prevalence of the incorporation of sphenoid sinuses' septum / septa in the carotid canal of the adult population., Materials and Methods: 296 computed tomography (CT) scans of the patients (147 females, 149 males), who did not present any pathology in the sphenoid sinuses, were evaluated in this retrospective analysis. Spiral CT scanner - Siemens Somatom Sensation 16 - was used to glean the medical images. Standard procedure applied in the option Siemens CARE Dose 4D. No contrast medium was administered. Multiplans reconstruction (MPR) tool was used in order to obtain frontal and sagittal planes from the transverse planes previously received., Results: Bilateral incorporation of the main septum (MS) in the carotid canal was not present in any of the patients, whereas unilateral incorporation was noticed in 21.96% of the patients (17.68% females, 26.17% males). On the right side it occurred in 11.82% of cases (10.88% females, 12.75% males), and on the left side in 10.14% of cases (6.8% females, 13.42% males). Bilateral incorporation of the additional septum (AS) was found in 8.45% of the patients (4.08% females, 12.75% males), whereas unilateral incorporation was noted in 28.37% of the patients. It was seen on the right side in 11.82% of cases (12.93% females, 10.74% males), and on the left side in 16.55% cases (15.65% females, 17.45% males). The most common variant was the incorporation of only one of the septa (either the MS or the AS) in the wall of the carotid canal unilaterally. Such situation took place in 30.07% of the patients (29.25% females, 30.87% males). Incorporation of two septa on the same side was noticed in 4.39% of cases (4.08% females, 4.7% males), and incorporation of three septa in 0.34% of cases (0.7% males)., Conclusions: The anatomy of the paranasal sinuses is varied to a great extent, hence performing a CT scan is crucial before the scheduled surgery, as it may lessen the unforeseeable surgical complications, that may result from the high prevalence of variants in the sinuses.

- Abstract
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive leukemia for which we developed a nationwide network to collect data from new cases diagnosed in France. In a retrospective, observational study of 86 patients (2000-2013), we described clinical and biological data focusing on morphologies and immunophenotype. We found expression of markers associated with plasmacytoid dendritic cell origin (HLA-DRhigh, CD303+, CD304+, and cTCL1+) plus CD4 and CD56 and frequent expression of isolated markers from the myeloid, B-, and T-lymphoid lineages, whereas specific markers (myeloperoxidase, CD14, cCD3, CD19, and cCD22) were not expressed. Fifty-one percent of cytogenetic abnormalities impact chromosomes 13, 12, 9, and 15. Myelemia was associated with an adverse prognosis. We categorized chemotherapeutic regimens into 5 groups: acute myeloid leukemia (AML)-like, acute lymphoid leukemia (ALL)-like, lymphoma (cyclophosphamide, doxorubicin, vincristine, and prednisone [CHOP])-like, high-dose methotrexate with asparaginase (Aspa-MTX) chemotherapies, and not otherwise specified (NOS) treatments. Thirty patients received allogeneic hematopoietic cell transplantation (allo-HCT), and 4 patients received autologous hematopoietic cell transplantation. There was no difference in survival between patients receiving AML-like, ALL-like, or Aspa-MTX regimens; survival was longer in patients who received AML-like, ALL-like, or Aspa-MTX regimens than in those who received CHOP-like regimens or NOS. Eleven patients are in persistent complete remission after allo-HCT with a median survival of 49 months vs 8 for other patients. Our series confirms a high response rate with a lower toxicity profile with the Aspa-MTX regimen, offering the best chance of access to hematopoietic cell transplantation and a possible cure., (© 2019 by The American Society of Hematology.)

- Abstract
We report here a case of primitive plasma cell leukemia with immunoglobulin (Ig) E. IgE myeloma is an exceptional variant of multiple myeloma, with a very poor prognosis. Its biological diagnosis requires specific analyzes in order to detect IgE gammopathy. Plasma cell leukemia (PCL) is also a very rare and very severe form of multiple myeloma. There are two variants: primitive PCL (pPCL) occurring de novo and secondary PCL (sPCL), evolution of a preexisting myeloma. Its diagnosis is essentially biological since it is defined by a blood plasmocytosis greater than 2 G/L or 20% of the leucocytes.

- Abstract
Isolated trisomy 8 (+8) is a frequent cytogenetic abnormality in the myelodysplastic syndromes (MDS), but its characteristics are poorly reported. We performed a retrospective study of 138 MDS patients with isolated +8, classified or reclassified as MDS (excluding MDS/myeloproliferative neoplasm). Myeloproliferative (MP) features were defined by the repeated presence of one of the following: white blood cell count >10 × 10
9 /l, myelemia (presence of circulating immature granulocytes with a predominance of more mature forms) >2%, palpable splenomegaly. Fifty-four patients (39·1%) had MP features: 28 at diagnosis, 26 were acquired during evolution. MP forms had more EZH2 (33·3% vs. 12·0% in non-MP, P = 0·047), ASXL1 (66·7% vs. 42·3%, P = 0·048) and STAG2 mutations (77·8% vs. 21·7%, P = 0·006). Median event-free survival (EFS) and overall survival (OS) were 25 and 27 months for patients with MP features at diagnosis, versus 28 (P = 0·15) and 39 months (P = 0·085) for those without MP features, respectively. Among the 57 patients who received hypomethylating agent (HMA), OS was lower in MP cases (13 months vs. 23 months in non-MP cases, P = 0.02). In conclusion, MP features are frequent in MDS with isolated +8. MP forms had more EZH2, ASXL1 and STAG2 mutations, responded poorly to HMA, and tended to have poorer survival than non-MP forms., (© 2018 British Society for Haematology and John Wiley & Sons Ltd.)- Published

- Abstract
Immunosuppressive treatment is a disease-modifying therapy for lower-risk myelodysplastic syndromes (MDS). However, IST is relatively rarely used and long-term outcomes of patients are seldom reported. We retrospectively studied outcomes of 20 patients with lower-risk non del 5q MDS with transfusion dependency, with horse or rabbit antithymocyte globulin ± ciclosporine A, and frontline eltrombopag in two of them. IPSS-R was low, intermediate and high in 30%, 55% and 10% of the patients, respectively. Fifty-five percent of the patients had hypocellular bone marrow (BM). Baseline mutations were detected in 31.5% of the patients and were more frequent in patients with normo/hypercellular MDS than in patients with hypocellular MDS. Transfusion independence rate for both red blood cells (RBC) and platelets was achieved in 45% of patients. RBC transfusion duration ≤6 months, B-cell counts >0.2 G/L and, marginally, BM blasts ≤2% were associated with higher transfusion independence rate. Age and cellularity did not influence the response rate. Median transfusion independence duration was 53 months. Cumulative incidence of progression to a more aggressive myeloid disease was 0 in patients without baseline mutations and 33% in patients with baseline mutations (P = .008). Median progression-free and overall survival after treatment onset and median overall survival after loss of transfusion independence were 45.5 months, 68 months and not reached, respectively. In conclusion, antithymocyte globulin ± ciclosporine A results in durable responses in MDS, irrespective of age, in patients with lower-risk disease without B-cell lymphopenia and treated early in the course of the disease., (Copyright © 2018 Elsevier Ltd.

- 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., (Published by the BMJ Publishing Group Limited.

- 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., (Copyright© Ferrata Storti Foundation.)

- 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%., (© 2013 John Wiley & Sons Ltd.)

- 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 2004-2011 and they correlated to the decrease of the drug pressure.

- Abstract
The newly developed, high throughput, Vitros 3600 immunoassay system associates different technologies on board: MicroWell (analytes immunocapture), MicroSensor (visible interference analysis), and Intellicheck (real time process control for analytical error detection). During a three months period, Vitros 3600 system, ease of use, practicability and MicroSensor technology efficiency have been tested using the following assays: betaHCG, troponin, ferritin, aHBcT, HBsAg, aHCV, AFP and CEA. Within-day and within-batch, between-calibration precisions are acceptable. Overall assay correlations versus the methods in use in our laboratory are good, despite small numerical differences that never affect clinical interpretation of the results. We have appreciated the system reliability, reinforced by the ease of use (simple software, on-board VDocs, continuous access to reagent and sample loading, reagent stability, very low noise (60 dB)), the quality of the results, MicroSensor and Intellicheck technologies efficiency, the short maintenance time and its traceability, and the very low liquid waste volume (5 L of liquid waste for 1600 tests). In conclusion and considering its practicability, the Vitros 3600 system is fully validated and well suited for our laboratory.

- 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
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
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
Objective: Prospectively evaluate the effect of cordocentesis on the umbilical, fetal cerebral and aortic circulation., Method: Fetal blood was sampled for diagnostic purposes in 21 pregnant women at 21 to 38 weeks gestation. Ten patients undergoing amniocentesis served as controls. The resistance index (RI) in the umbilical and middle cerebral arteries and the mean blood velocity (Vm) in the descending aorta were measured with pulsed Doppler before and after blood sampling. Variations in umbilical and cerebral RI and in aortic Vm were recorded., Results: There was a significant drop in both umbilical RI (mean +/- SD = -0.049 +/- 0.078; p = 0.009) and middle cerebral RI (-0.077 +/- 0.058; p < 0.0001) after cordocentesis. The drop in umbilical RI was greater when the second Doppler measurement was made early, when the blood was sampled transplacentally and in early gestational age. Reduction in fetal cerebral artery RI was also greater for transplacental puncture. The fetal descending aorta Vm did not change significantly after blood sampling. There were no variations in Doppler index before and after amniocentesis., Conclusions: Changes in blood flow velocity waveforms as measured by pulsed Doppler in the umbilical and fetal cerebral arteries can be induced by fetal blood sampling. Decreased resistance in the placenta and fetal circulation would imply release of nitric oxide.

- 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
Automated differential counting systems deprive laboratories of blood smear study and so malaria risks not to be diagnosed if plasmodium search is not prescribed by the physician. Some abnormalities (atypical lymphocytes called LUC and thrombopenia) can induce a blood smear. But a study of 96 patients shows that, during the first analysis, these abnormalities can miss for nearly a third of one's case. So it is very important to prescribe malaria search on blood smears when there is the least clinical symptom.

- 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.
