    Full Text Available Abstract Background Diamond-Blackfan anaemia (DBA is a rare inherited red cell hypoplasia characterised by a defect in the maturation of erythroid progenitors and in some cases associated with malformations. Patients have an increased risk of solid tumors. Mutations have been found in several ribosomal protein (RP genes, i.e RPS19, RPS24, RPS17, RPL5, RPL11, RPL35A. Studies in haematopoietic progenitors from patients show that haplo-insufficiency of an RP impairs rRNA processing and ribosome biogenesis. DBA lymphocytes show reduced protein synthesis and fibroblasts display abnormal rRNA processing and impaired proliferation. Results To evaluate the involvement of non-haematopoietic tissues in DBA, we have analysed global gene expression in fibroblasts from DBA patients compared to healthy controls. Microarray expression profiling using Affymetrix GeneChip Human Genome U133A 2.0 Arrays revealed that 421 genes are differentially expressed in DBA patient fibroblasts. These genes include a large cluster of ribosomal proteins and factors involved in protein synthesis and amino acid metabolism, as well as genes associated to cell death, cancer and tissue development. Conclusion This analysis reports for the first time an abnormal gene expression profile in a non-haematopoietic cell type in DBA. These data support the hypothesis that DBA may be due to a defect in general or specific protein synthesis.

    Full Text Available Migraine and vertigo are common disorders, with lifetime prevalences of 16% and 7% respectively, and co-morbidity around 3.2%. Vestibular syndromes and dizziness occur more frequently in migraine patients. We investigated bedside clinical signs indicative of vestibular dysfunction in migraineurs.Objective To test the hypothesis that vestibulo-ocular reflex, vestibulo-spinal reflex and fall risk (FR responses as measured by 14 bedside tests are abnormal in migraineurs without vertigo, as compared with controls.Method Cross-sectional study including sixty individuals – thirty migraineurs, 25 women, 19-60 y-o; and 30 gender/age healthy paired controls.Results Migraineurs showed a tendency to perform worse in almost all tests, albeit only the Romberg tandem test was statistically different from controls. A combination of four abnormal tests better discriminated the two groups (93.3% specificity.Conclusion Migraine patients consistently showed abnormal vestibular bedside tests when compared with controls.

    Sideroblastic Anaemias are characterised by a) chronic hypochromic anemia, b) ringed sideroblasts in the bone marrow, c) an increase in total body iron, d) ineffective erythropoiesis and e) often abnormal concentrations of F.E.P. A classification of Sideroblastic Anaemia is given and the pathophysiology of Sideroblastic Anaemia is discussed. A series of seven paediatric cases with Sideroblastic Anaemia is presented and the results of studies of the iron, vitamin B6 and porphyrin metabolism are discussed. In two cases arguments for an ALA-synthetase deficiency are given. All five males were diagnosed as hereditary X-linked Sideroblastic Anaemia, one female as I.R.S.A. and the other female, who showed the features of the X-linked type, as congenital Sideroblastic Anaemia.

    BACKGROUND: Chronic inflammatory diseases may be associated with anaemia of inflammation. Hidradenitis suppurativa is a chronic inflammatory dermatological disease associated with metabolic comorbidities, low quality of life and fatigue. Anaemia may cause fatigue, and it has been hypothesized...... that HS-related fatigue may be partly due to anaemia. OBJECTIVE: Our objective was to investigate a possible association between HS and anaemia. METHODS: We performed a hospital-based and population-based cross-sectional study investigating the red blood cell profile, i.e. haemoglobin. RESULTS: We...... revealed that 60% had normocytic anaemia and 40% microcytic anaemia, in concordance with anaemia of inflammation. CONCLUSION: In contrast to our hypothesis, this study showed that HS is not associated with anaemia. Thus, anaemia may not be the cause of the described fatigue in HS patients. Furthermore...

  5. CLINICAL PROFILE OF ANAEMIA IN A TERTIARY CARE HOSPITAL

    Full Text Available BACKGROUND Anaemia causes a reduction in the oxygen carrying capacity of the blood resulting in tissue hypoxia. Cardiac output at rest is not usually increased in most chronic anaemia until haemoglobin levels fall below 7 g/dL, but abnormal rise in output with exercise may occur with levels as high as 10 g/dL. The increase in cardiac output has been observed to correlate well with the degree of anaemia. Other compensatory mechanisms to chronic anaemia available to the body include decreased circulation time and increased tissue oxygen uptake. The latter is facilitated by a shift to the right of the oxygen haemoglobin dissociation curve. Cardiomegaly may also be as a result of the increased workload on the heart from the increased viscosity of blood in anaemia patients. Anaemia in the elderly is an extremely common problem that is associated with increased mortality and poorer health-related quality of life, regardless of the underlying cause of the low haemoglobin. A study of anaemia in elderly patients found a wide variation in prevalence, ranging from 2.9% to 61% in men and 3.3% to 41% in women. Higher rates were found in hospitalised patients than in community dwellers. It is easy to overlook anaemia in the elderly, since such symptoms as fatigue, weakness, or shortness of breath may be attributed to the ageing process itself. Our objective is to show the prevalence of anaemia even in a tertiary health care centre. METHODS One hundred patients were identified who were admitted in the Department of Medicine, Deccan College of Medical Sciences. Among the 100 patients, 38 were male and 62 were female. The study was conducted from Jan 2014 To Jan 2015. Patients having haemoglobin less than 10 g% in the medical wards were enrolled in the study. RESULTS Among the 100 patients, 38 were male and 62 were female. The average haemoglobin was 6.4 g%, the lowest being 2.8 g%. Peripheral blood smear showed hypochromic picture in 58, macrocytic picture in

    CD1d is a member of CD1 family of transmembrane glycoproteins, which represent antigen-presenting molecules. Immunofluorescent staining methods were utilized to examine expression pattern of CD1d in human testicular specimens. In testis showing normal spermatogenesis, a strong CD1d cytoplasmic expression was seen the Sertoli cells, spermatogonia, and Leydig cells. A moderate expression was observed in the spermatocytes. In testes showing maturation arrest, CD1d expression was strong in the Sertoli cells and weak in spermatogonia and spermatocytes compared to testis with normal spermatogenesis. In Sertoli cell only syndrome, CD1d expression was strong in the Sertoli and Leydig cells. This preliminary study displayed testicular infertility-related changes in CD1d expression. The ultrastructural changes associated with with normal and abnormal spermatogenesis are open for further investigations.

    Heat shock proteins (HSPs) are molecular chaperones involved in protein folding, assembly and transport, and which play critical roles in the regulation of cell growth, survival and differentiation. We set out to test the hypothesis that HSP27 protein is expressed in the human testes and its expression varies with the state of spermatogenesis. HSP27 expression was examined in 30 human testicular biopsy specimens (normal spermatogenesis, maturation arrest and Sertoli cell only syndrome, 10 cases each) using immunofluorescent methods. The biopsies were obtained from patients undergoing investigations for infertility. The seminiferous epithelium of the human testes showing normal spermatogenesis had a cell type-specific expression of HSP27. HSP27 expression was strong in the cytoplasm of the Sertoli cells, spermatogonia, and Leydig cells. Alternatively, the expression was moderate in the spermatocytes, weak in the spermatids and absent in the spermatozoa. In testes showing maturation arrest, HSP27 expression was strong in the Sertoli cells, weak in the spermatogonia, and spermatocytes. It was absent in the spermatids and Leydig cells. In Sertoli cell only syndrome, HSP27 expression was strong in the Sertoli cells and absent in the Leydig cells. We report for the first time the expression patterns of HSP27 in the human testes and show differential expression during normal spermatogenesis, indicating a possible role in this process. The altered expression of this protein in testes showing abnormal spermatogenesis may be related to the pathogenesis of male infertility.

  10. ANAEMIA DURING PREGNANCY

    Full Text Available Nutritional anaemia due to iron and folate deficiency is a major global Public Health problem. South Asia ranks among the regions, which have the highest prevalence of anaemia in the world and India perhaps has the highest prevalence of anaemia among the South Asian countries. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50% of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. Many times anaemia is directly or indirectly responsible for maternal deaths. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. Maternal anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in preganancy can lead to substantial reduction in under nutrition in childhood, adolescence and improvement in adult height.

  11. Increased recombination frequency showing evidence of loss of interference is associated with abnormal testicular histopathology.

    Nondisjunction leading to aneuploid gametes has been linked genetically to both increases and decreases in recombination frequency on the aneuploid chromosome. In the present study, we present physical evidence of increased frequency of recombination nodules as measured by Mut-S-like homologue-1 (MLH1) foci on pachytene chromosomes from sterile male mice homozygous for a mutation in the protein phosphatase 1cgamma (PP1cgamma) gene. The pattern of elevated recombination frequency in PP1cgamma mutant spermatocytes is consistent with a loss of interference. Previous studies demonstrated: (1) spermiogenesis is impaired starting at step 8 with a severe reduction in elongating and condensed spermatids; (2) spermatids and sperm exhibit elevated rates of DNA fragmentation; and (3) haploid gametes exhibit elevated levels of aneuploidy. Morphometric analysis of developing testes revealed that the first wave of meiosis proceeds at a normal rate in mutant testes, a surprising result given that the PP1 inhibitor okadaic acid has been shown to accelerate progression of spermatocytes from pachytene to the first meiotic division (MI). Evidence of abnormal testicular histopathology is apparent at 3 weeks, before the appearance of haploid gametes, eliminating the possibility that the mutant phenotype is caused by the presence of abnormal spermatids, but coincident with the appearance of the first set of mid to late pachytene spermatocytes. These observations lead us to conclude that the PP1cgamma mutation causes a complex phenotype, including subtle adverse effects on meiosis, possibly mediated by defective signaling between germ cells and Sertoli cells.

  12. Pre-operative anaemia.

    Pre-operative anaemia is a relatively common finding, affecting a third of patients undergoing elective surgery. Traditionally associated with chronic disease, management has historically focused on the use of blood transfusion as a solution for anaemia in the peri-operative period. Data from large series now suggest that anaemia is an independent risk associated with poor outcome in both cardiac and non-cardiac surgery. Furthermore, blood transfusion does not appear to ameliorate this risk, and in fact may increase the risk of postoperative complications and hospital length of stay. Consequently, there is a need to identify, diagnose and manage pre-operative anaemia to reduce surgical risk. Discoveries in the pathways of iron metabolism have found that chronic disease can cause a state of functional iron deficiency leading to anaemia. The key iron regulatory protein hepcidin, activated in response to inflammation, inhibits absorption of iron from the gastrointestinal tract and further reduces bioavailability of iron stores for red cell production. Consequently, although iron stores (predominantly ferritin) may be normal, the transport of iron either from the gastrointestinal tract or iron stores to the bone marrow is inhibited, leading to a state of 'functional' iron deficiency and subsequent anaemia. Since absorption from the gastrointestinal tract is blocked, increasing oral iron intake is ineffective, and studies are now looking at the role of intravenous iron to treat anaemia in the surgical setting. In this article, we review the incidence and impact of anaemia on the pre-operative patient. We explain how anaemia may be caused by functional iron deficiency, and how iron deficiency anaemia may be diagnosed and treated.

    Hyperextension of the knee in stance (knee recurvatum) is a common disorder in patients with spastic cerebral palsy (CP). A group 35 children with CP (47 lower limbs) was divided into two subgroups according to the timing of maximum knee extension during the stance phase of gait. Gait analysis and musculoskeletal modelling data were compared with a control group of 12 normally developing children. We observed no difference in kinematics between the CP groups who showed an equinus position of the foot at initial contact. Both groups showed increased external extensor moments across the knee. The muscle-tendon lengths of the hamstrings were abnormally long at initial contact, and in both recurvatum groups, contracted faster compared with the control group. Surface electromyography revealed prolonged activity of the hamstrings in stance and early activation in swing. Abnormally long hamstrings at initial contact together with equinus position of the foot are the main causes of genu recurvatum in children with CP.

    In rodents, insufficient thyroid hormone (TH) gestationally has adverse effects on cerebral cortex development. Comparable studies of humans examining how TH insufficiency affects cortical morphology are limited to children with congenital hypothyroidism or offspring of hypothyroxinemic women; effects on cortex of children born to women with clinically diagnosed hypothyroidism are not known. We studied archived MRI scans from 22 children aged 10–12 years born to women treated for preexisting or de novo hypothyroidism in pregnancy (HYPO) and 24 similar age and sex controls from euthyroid women. FreeSurfer Image Analysis Suite software was used to measure cortical thickness (CT) and a vertex-based approach served to compare HYPO versus control groups and Severe versus Mild HYPO subgroups as well as to perform regression analyses examining effects of trimester-specific maternal TSH on CT. Results showed that relative to controls, HYPO had multiple regions of both cortical thinning and thickening, which differed for left and right hemispheres. In HYPO, thinning was confined to medial and mid-lateral regions of each hemisphere and thickening to superior regions (primarily frontal) of the left hemisphere and inferior regions (particularly occipital and temporal) of the right. The Severe HYPO subgroup showed more thinning than Mild in frontal and temporal regions and more thickening in bilateral posterior and frontal regions. Maternal TSH values predicted degree of thinning and thickening within multiple brain regions, with the pattern and direction of correlations differing by trimester. Notably, some correlations remained when cases born to women with severe hypothyroidism were removed from the analyses, suggesting that mild variations of maternal TH may permanently affect offspring cortex. We conclude that maternal hypothyroidism during pregnancy has long-lasting manifestations on the cortical morphology of their offspring with specific effects reflecting both

    INTRODUCTION Anaemia is common in rheumatoid arthritis (RA). Clinicians may focus on rheumatological issues and assume anaemia of chronic disease (ACD). This study challenged this assumption and investigated the causes of anaemia in a large cohort of RA patients to assess its implications. METHODS The hospital where the study was conducted monitors regular full blood count and erythrocyte sedimentation rate (ESR) monthly in all RA patients on disease modifying drugs to assess efficacy and safety. A computerised system identifies and records abnormal results. The database for 2009 was interrogated to find all patients with two consecutive haemoglobin values anaemia (IDA), ACD, macrocytic anaemia (MCA) or another cause. All results of further tests investigating the anaemia were recorded. RESULTS Among 2000 RA patients on the system, 199 (10%) were identified as having anaemia over a year. Of these, 90 had IDA, 78 had ACD, 25 had MCA, and 6 had postoperative anaemia. Among 90 patients with IDA, investigations were performed in 53, with 23 normal. An explanation for IDA was found in 30: gastrointestinal bleeding in 25, gynaecological blood loss in 3, and urinary bleeding in 2. Among 78 patients with ACD, response to intensification of RA treatment occurred in 45, but erythropoietin therapy was required in 9. Within the 25 patients with MCA, 12 had unrecognised vitamin B(12) deficiency, 4 drug induced changes, 3 myeloid malignancy, 2 hypothyroidism, and 2 alcoholism. CONCLUSIONS Anaemia in RA is common, multifactorial, and potentially both serious and correctable. Established malignancy was present in 10 patients and premalignancy in a further 10 (10% of total). Treatable causes were commonly identified. Clinicians need to investigate the nature and cause of persistent anaemia, and must not assume it to be simply ACD without evidence.

    Mood disorders are associated with alterations in serotonergic system, deficient BDNF (brain-derived neurotrophic factor) signaling and abnormal synaptic plasticity. Increased degradation and reduced functions of NCAM (neural cell adhesion molecule) have recently been associated with depression and NCAM deficient mice show depression-related behavior and impaired learning. The aim of the present study was to investigate potential changes in serotonergic and BDNF systems in NCAM knock-out mice. Serotonergic nerve fiber density and SERT (serotonin transporter) protein levels were robustly reduced in the hippocampus, prefrontal cortex and basolateral amygdala of adult NCAM(-)(/-) mice. This SERT reduction was already evident during early postnatal development. [(3)H]MADAM binding experiments further demonstrated reduced availability of SERT in cell membranes of NCAM(-)(/-) mice. Moreover, the levels of serotonin and its major metabolite 5-HIAA were down regulated in the brains of NCAM(-)(/-) mice. NCAM(-)(/-) mice also showed a dramatic reduction in the BDNF protein levels in the hippocampus and prefrontal cortex. This BDNF deficiency was associated with reduced phosphorylation of its receptor TrkB. Importantly, chronic administration of antidepressant amitriptyline partially or completely restored these changes in serotonergic and BDNF systems, respectively. In conclusion, NCAM deficiency lead to prominent and persistent abnormalities in brain serotonergic and BDNF systems, which likely contributes to the behavioral and neurobiological phenotype of NCAM(-/-) mice.

    Anaemia affects roughly a third of the world's population; half the cases are due to iron deficiency. It is a major and global public health problem that affects maternal and child mortality, physical performance, and referral to health-care professionals. Children aged 0-5 years, women of childbearing age, and pregnant women are particularly at risk. Several chronic diseases are frequently associated with iron deficiency anaemia--notably chronic kidney disease, chronic heart failure, cancer, and inflammatory bowel disease. Measurement of serum ferritin, transferrin saturation, serum soluble transferrin receptors, and the serum soluble transferrin receptors-ferritin index are more accurate than classic red cell indices in the diagnosis of iron deficiency anaemia. In addition to the search for and treatment of the cause of iron deficiency, treatment strategies encompass prevention, including food fortification and iron supplementation. Oral iron is usually recommended as first-line therapy, but the most recent intravenous iron formulations, which have been available for nearly a decade, seem to replenish iron stores safely and effectively. Hepcidin has a key role in iron homoeostasis and could be a future diagnostic and therapeutic target. In this Seminar, we discuss the clinical presentation, epidemiology, pathophysiology, diagnosis, and acute management of iron deficiency anaemia, and outstanding research questions for treatment.

    Background Type-2 diabetes mellitus (T2DM) accelerates cognitive aging and increases risk of Alzheimer’s disease. Rodent models of T2DM show altered synaptic plasticity associated with reduced learning and memory. Humans with T2DM also show cognitive deficits, including reduced learning and memory, but the relationship of these impairments to the efficacy of neuroplastic mechanisms has never been assessed. Objective Our primary objective was to compare mechanisms of cortical plasticity in humans with and without T2DM. Our secondary objective was to relate plasticity measures to standard measures of cognition. Methods A prospective cross-sectional cohort study was conducted on 21 adults with T2DM and 15 demographically-similar non-diabetic controls. Long-term potentiation-like plasticity was assessed in primary motor cortex by comparing the amplitude of motor evoked potentials (MEPs) from single-pulse transcranial magnetic stimulation before and after intermittent theta-burst stimulation (iTBS). Plasticity measures were compared between groups and related to neuropsychological scores. Results In T2DM, iTBS-induced modulation of MEPs was significantly less than controls, even after controlling for potential confounds. Furthermore, in T2DM, modulation of MEPs 10-min post-iTBS was significantly correlated with Rey Auditory Verbal Learning Task (RAVLT) performance. Conclusion Humans with T2DM show abnormal cortico-motor plasticity that is correlated with reduced verbal learning. Since iTBS after-effects and the RAVLT are both NMDA receptor-dependent measures, their relationship in T2DM may reflect brain-wide alterations in the efficacy of NMDA receptors. These findings offer novel mechanistic insights into the brain consequences of T2DM and provide a reliable means to monitor brain health and evaluate the efficacy of clinical interventions.

    Aplastic anaemia (AA) can precede acute lymphoblastic leukaemia (ALL) in 2% of children but this is rarely reported to occur in adults. A 21-year-old male presented with bone marrow failure and bone marrow biopsy showed a profoundly hypocellular marrow. He recovered spontaneously but represented 2 months later when he was diagnosed with pre-B acute lymphoblastic leukaemia. Chromosomal examination revealed 46,XY,del(9)(q13q34). To the best of our knowledge this is the first case to be reported of aplasia preceding ALL with 9q minus as the sole chromosomal abnormality.

    Acceptance of lower transfusion thresholds and shorter post-operative stays results in patients leaving hospital after surgery with lower haemoglobin (Hb) than previously. We undertook a prospective observational study to assess the haematological response to post-operative anaemia and to determine the utility of quality of life (QoL) measures in assessing the impact of anaemia on such patients. Thirty patients undergoing unilateral hip arthroplasty had blood samples taken and QoL questionnaires administered pre-operatively and at 7, 28 and 56 days post-operatively. Increased erythropoiesis was evident at day 7 post-operatively. Approximately two-thirds of the post-operative Hb deficit was corrected by day 28. There was evidence of functional iron deficiency in more than one-quarter of patients at day 56. QoL scores used did not show any relationship with Hb in the post-operative period. Red cell 2,3-diphosphoglycerate (2,3DPG) levels increased in proportion to the degree of post-operative anaemia. We concluded that substantial recovery of Hb occurs between day 7 and day 28 post-operatively. Complete recovery of Hb may be delayed beyond day 56 due to development of iron deficiency. Patients are at significant risk of developing post-operative iron deficiency depending on operative blood loss and pre-operative iron stores. Increased red cell 2,3DPG may offset the effect of anaemia on oxygen delivery. We found no evidence that anaemia produces a measurable effect on chosen QoL scores in the post-operative period.

    Individualized strategies for managing renal anaemia with erythropoiesis-stimulating agents (ESAs) need to be advanced. Recent outcomes from clinical studies prompted a narrowing of the guideline-recommended haemoglobin target (11-12 g/dL) due to increased mortality and morbidity when targeting higher haemoglobin concentrations. Maintaining a narrow target is a clinical challenge, as haemoglobin concentration tends to fluctuate. The goal of individualized treatment is to achieve the haemoglobin target at the lowest ESA dose while avoiding significant fluctuations in haemoglobin concentrations and persistently low or high concentrations. This may require changes to the ESA dose and dosing frequency over the course of treatment.

    Background Patients with myelodysplastic syndrome (MDS) display a very diverse pattem. In this study, we investigated prognostic factors and survival rate in adult patients with MDS refractory anaemia (MDS-RA) diagnosed according to French-American-British classification and evaluated the International Prognostic Scoring System (IPSS) for Chinese patients.Methods A multi-center study on diagnosis of MDS-RA was conducted to charactedze the clinical features of Chinese MDS patients. The morphological criteria for the diagnosis of MDS-RA were first standardized. Clinical data of 307 MDS-RA patients collected from Shanghai, Suzhou and Beijing from 1995 to 2006 were analyzed using Kaplan-Meier curve, log rank and Cox regression model.Results The median age of 307 MDS-RA cases was 52 years. The frequency of 2 or 3 lineage cytopenias was 85.6%. Abnormal karyotype occurred in 35.7% of 235 patients. There were 165 cases (70.2%) in the good IPSS cytogenetic subgroup, 44 cases (18.7%) intermediate and 26 cases (11.1%) poor. IPSS showed 20 (8.5%) categodzed as low dsk,195 cases (83.0%) as intermediate-I risk and 20 cases (8.5%) as intermediate-ll dsk. The 1-, 2-, 3-, 4- and 5-year survival rates were 90.8%, 85.7%, 82.9%, 74.9% and 71.2% respectively. Fifteen cases (4.9%) transformed to acute myeloid leukaemia (median time 15.9 months, range 3-102 months). Lower white blood ceil count (<1.5x109/L), platelet count (<30x109/L) and cytogenetic abnormalities were independent prognostic factors by multivariate analysis, but age (≥65 years), IPSS cytogenetic subgroup and IPSS risk subgroup were not independent prognostic factors associated with survival time.Conclusions Chinese patients were younger, and had lower incidence of cytogenetic abnormalities, more severe cytopenias but a more favourable prognosis than Western patients. The major prognostic factors were lower white blood cell count, lower platelet count and fewer abnormal karyotypes. The intemational prognostic scodng

    Measurement of arterial oxygen saturation by pulse oximetry was performed in two patients with acute and chronic anaemia (haemoglobin concentrations: 2.9 mmol/l (4.7 g/dl) and 1.9 mmol/l (3.0 g/dl), respectively) using a Radiometer OXI and a Nellcor N-200 pulse oximeter. The two oximeters read...... alternating different values in the two patients. In conclusion, pulse oximeters are able to give a value for oxygen saturation even at extreme anaemia, and when a high value is given, it possibly reflects arterial oxygen saturation. The value of pulse oximetry in severe anaemia is discussed....

    Ischemic pituitary necrosis due to severe postpartum haemorrhage called Sheehan's syndrome is a rare cause of hypopituitarism in the western world, but much more common in developing countries. A 45-year-old female patient being a war refugee from Chechnya with severe anaemia and fatigue was diagnosed at our outpatient department with Sheehan's syndrome after severe postpartum haemorrhage and emergency hysterectomy 15 years ago. Panhypopituitarism was adequately treated with substitution of hydrocortisone, thyroxine and transdermal oestrogen which resulted in haemoglobin increase to nearly normal levels and symptoms improved immediately. Severe anaemia caused by panhypopituitarism shows the importance of the hormonal system for erythropoiesis. Clinical and basic scientific evidence indicates thyroidal hormones to be the main cause.

    Children with autism spectrum disorder (ASD) and age-matched typically-developing (TD) peers were tested on two forms of eyeblink conditioning (EBC), a Pavlovian associative learning paradigm where subjects learn to execute an appropriately-timed eyeblink in response to a previously neutral conditioning stimulus (CS). One version of the task, trace EBC, interposes a stimulus-free interval between the presentation of the CS and the unconditioned stimulus (US), a puff of air to the eye which causes the subjects to blink. In delay EBC, the CS overlaps in time with the delivery of the US, usually with both stimuli terminating simultaneously. ASD children performed normally during trace EBC, exhibiting no differences from TD subjects with regard to the learning rate or the timing of the conditioned response. However, when subsequently tested on delay EBC, subjects with ASD displayed abnormally-timed conditioned eye blinks that began earlier and peaked sooner than those of TD subjects, consistent with previous findings. The results suggest an impaired ability of children with ASD to properly time conditioned eye blinks which appears to be specific to delay EBC. We suggest that this deficit may reflect a dysfunction of the cerebellar cortex in which increases in the intensity or duration of sensory input can temporarily disrupt the accuracy of motor timing over short temporal intervals.

    Full Text Available Objective This study aims to evaluate “in vivo” the integrity of the normal-appearing spinal cord (NASC in patients with multiple sclerosis (MS compared to controls, using diffusion tensor MR imaging. Methods We studied 32 patients with MS and 17 without any neurologic disorder. Fractional anisotropy (FA, axial diffusivity (AD, radial diffusivity (RD and mean diffusivity (MD were calculated within regions of interest at C2 and C7 levels in the four columns of the spinal cord. Results At C2, FA value was decreased in MS patients. Besides, RD value was higher in MS than in controls. At C7, MD values were increased in MS. Conclusion The NASC in the right column of the cervical spinal cord showed abnormal FA, RD and MD values, which is possibly related to demyelination, since the FA abnormality was related to the RD and not to the AD.

    Anaemia in children is a public health concern in Mexico; Federal food assistance programmes are being implemented to prevent it. We undertook this research to investigate the indirect association between food assistance programmes (FAP) and anaemia through dietary and socio-economic conditions of beneficiary children. A structural equation model (SEM) was constructed to assess associations among FAP, dietary and socio-economic conditions, as well as anaemia. A cross-sectional comparative study was conducted based on a sample of 1214 households with children Prospera and rescue from malnutrition with amaranth (RMA) and a comparison group in San Luis Potosí, Mexico. The SEM and a decomposition effect analysis revealed the existence of a significant indirect association of FAP on the prevalence of anaemia via dietary and socio-economic conditions in children under 5 years old. The Prospera assistance programme showed a significant indirect positive association with the prevalence of anaemia (standard coefficient=0·027, P<0·031), and the RMA programme showed a significant indirect negative association with the prevalence of anaemia (standard coefficient=-0·029, P=0·047). There was a direct association between FAP and dietary and socio-economic conditions. FAP could indirectly modify the prevalence of anaemia in young children with a direct improvement on dietary and socio-economic conditions. The unexpected finding of the association between RMA, dietary and socio-economic conditions and the prevalence of anaemia reflects differences in the focus of the programmes.

    Late patronage of antenatal care by women in low-resource areas makes timely intervention at correcting anaemia difficult. This study aimed to identify modifiable sociodemographic factors that predict anaemia before commencing antenatal care and make appropriate recommendation. A survey of sociodemographic features and haemoglobin concentrations of 232 women booking for antenatal care was conducted. Anaemia was diagnosed in 119 (51.3%), of which 87 (37.5%) had mild anaemia and 32 (13.8%) were moderately anaemic. There was no severe anaemia. Anaemia was highest among respondents who were 35 years of age, Muslims, of Igbo ethnicity (64.3%), single (55.0%), student/unemployed (58.8%), nulliparous (57.3%) and those who registered at 21 weeks' gestation (54.2%). Only occupation of the woman showed association with anaemia before antenatal care (p 0.007). A personal source of income may reduce anaemia in pregnancy; and it is advisable to have a social welfare package for unemployed pregnant women.

    Anaemia is a common problem in premature infants and is generally easy to treat with iron supplementation. If the anaemia persists despite appropriate correction of deficiencies, more extensive evaluation is required. We describe a case of a premature male infant with a production-deficient anaemia without metabolic deficiencies, eventually identified as anaemia of prematurity. This type of anaemia is commonly diagnosed but its highly variable and complex aetiology and phenotype are often poorly understood. A probable explanation for the anaemia of prematurity in this case was a transient iron incorporation defect, identifiable by high levels of zinc protoporphyrin.

    Full Text Available Objective: The study explores the association between the household environment and the prevalence of anaemia among children under the age of five years in India.Data and methodology: The study is based on 52,868 children under the age of five years, included in India’s National Family Health Survey-3. The outcome variable was the prevalence of anaemia. To understand the role of environment in determining child anaemia, step wise logistic regression models consisting of environmental, child, socio-economic and media exposure variables were applied.Results: The occurrence of childhood anaemia was higher in the North Eastern and Eastern regions compared to all other regions of India. Unclean fuel use, poor toilet facilities, staying in non-concrete house, exposure to smoking were important variables determining the prevalence of anaemia. Smoking when it was controlled with only socio economic factors showed lesser impact on anaemia but when it got adjusted with socio-economic, child and media variables together it showed an important impact as it increased the risk of anaemia. Conclusion: Children under five years of age generally stay inside their house and are more exposed to the household environment. Thus, among these children there are multiple risk factors causing anaemia along with the nutritional deficiencies. Better resources are needed to educate the public and to increase awareness for improved hygiene, sanitation and housing facilities, health and nutrition etc. Along with a wider programme to manage nutritional deficiency anaemia in children less than five years, there should be a holistic approach towards anaemia control inculcating household environmental conditions and socio economic determinants.

    Anaemia defined as a haemoglobin level <13 g/dl in men and <12 g/dl in women is common in older people and associated with numerous health consequences. The aim of this study was to systematically review all published data from the past 30 years that studied the association between anaemia and cognitive performance in people aged 65 years and over. An English and French Medline and Cochrane Library search ranging from 1979 to 2011 indexed under the Medical Subject Heading (MeSH) terms 'haemoglobin' or 'anaemia' combined with the terms 'dementia' or 'cognition disorders' or 'memory disorders' or 'orientation' or 'executive functions' or 'attention' or 'brain' or 'neuropsychological tests' was performed. Ninety-eight studies were selected. The following specific conditions were excluded: cancer, chronic kidney diseases, chronic heart disease and post-operative cognitive dysfunction. Five observational studies and six prospective cohort studies were included in the final analysis. According to the studies, the number of participants ranged from 302 to 2250 community-dwelling older people aged 55 years or over. Four studies considered the association between haemoglobin concentration and global cognitive functions, another three examined the association between haemoglobin concentration and the incidence of dementia, and four studies evaluated some specific aspects of cognition. A significant positive association was shown between anaemia and global cognitive decline as well as the incidence of dementia. A significant association was also shown between anaemia and executive functions. This systematic review shows a probable association between anaemia and cognitive performances, particularly with executive functions.

    1978-12-01

    Lateral X-ray pictures of the skull in certain several and chronic disorders of the blood as thalassaemia, congenital haemolytic anaemia, sickle cell anaemia and iron deficiency disease show frequently changes of the outlines of the cranial bones. They consist of a double contour of the outer cranial border and on the interior side below the sagittal sutura of a band-like shadow or of multiple stripes and lines running parallel to the carnial vault. They concern the parietal bones and may extend from the bregma till to the lamda or occupy only a part of this distance. The roentgenological features are due to the enlargement of the crainal bones, the bulging out of both parietal bondes, the sometimes enlarged and deepened borders of the sulcus sagittalis superior and particularly to the furrow and depression on the skull above the sagittal suture caused by the protruding parietal bones on both sides. As these different abnormal structures must be passed by the picturing X-ray, effects of superposition and interference are produced. Longitudinal ridges or bony edges which could explain the roentgenological findings could not be established. Since the peculiar alterations of the cranial bones are mainly found in the mentioned blood disorders, where they are caused by the overgrowing red marrow, they also display the same roentgenological features. These features are, therefore, a characteristic sign of these diseases.

  17. DNA methylation patterns in tissues from mid-gestation bovine foetuses produced by somatic cell nuclear transfer show subtle abnormalities in nuclear reprogramming

    2010-03-01

    Full Text Available Abstract Background Cloning of cattle by somatic cell nuclear transfer (SCNT is associated with a high incidence of pregnancy failure characterized by abnormal placental and foetal development. These abnormalities are thought to be due, in part, to incomplete re-setting of the epigenetic state of DNA in the donor somatic cell nucleus to a state that is capable of driving embryonic and foetal development to completion. Here, we tested the hypothesis that DNA methylation patterns were not appropriately established during nuclear reprogramming following SCNT. A panel of imprinted, non-imprinted genes and satellite repeat sequences was examined in tissues collected from viable and failing mid-gestation SCNT foetuses and compared with similar tissues from gestation-matched normal foetuses generated by artificial insemination (AI. Results Most of the genomic regions examined in tissues from viable and failing SCNT foetuses had DNA methylation patterns similar to those in comparable tissues from AI controls. However, statistically significant differences were found between SCNT and AI at specific CpG sites in some regions of the genome, particularly those associated with SNRPN and KCNQ1OT1, which tended to be hypomethylated in SCNT tissues. There was a high degree of variation between individuals in methylation levels at almost every CpG site in these two regions, even in AI controls. In other genomic regions, methylation levels at specific CpG sites were tightly controlled with little variation between individuals. Only one site (HAND1 showed a tissue-specific pattern of DNA methylation. Overall, DNA methylation patterns in tissues of failing foetuses were similar to apparently viable SCNT foetuses, although there were individuals showing extreme deviant patterns. Conclusion These results show that SCNT foetuses that had developed to mid-gestation had largely undergone nuclear reprogramming and that the epigenetic signature at this stage was not a

    Full Text Available Background: Anaemia is the most common nutritional deficiency observed globally. Anaemia worsens during pregnancy leading to adverse maternal and fetal outcome. Dibrugarh district has the highest maternal mortality in the country, one of the major factor being anaemia during pregnancy. Aims & Objectives: To assess the prevalence and socio-demographic determinants of anaemia in pregnant women of Dibrugarh District. Material & Methods: A community based, cross-sectional study was conducted in a block selected randomly. Study period was for the period from May’2015 to February’2016. Study sample included 290 participants. Results: Prevalence of anaemia among study participants was found to be 73.1%. (Mild 10%, moderate 43.1 % and severe 20%. Mean haemoglobin of study subjects was 9.07±2.26 g/dl. Average age of the study subjects was 23.24±4. Majority (27.2% had their education upto primary school level and belong to class IV socioeconomic status. Univariate analysis and multiple logistic regression analysis shows educational qualification, socioeconomic status and type of housing are statistically associated with anaemia during pregnancy. Conclusion: Anaemia is rampant in the community needing urgent action to prevent morbidity amongst both mother and child

    Germline mutations affecting telomere maintenance or DNA repair may, respectively, cause dyskeratosis congenita or Fanconi anaemia, two clinically related bone marrow failure syndromes. Mice expressing p53(Δ31), a mutant p53 lacking the C terminus, model dyskeratosis congenita. Accordingly, the increased p53 activity in p53(Δ31/Δ31) fibroblasts correlated with a decreased expression of 4 genes implicated in telomere syndromes. Here we show that these cells exhibit decreased mRNA levels for additional genes contributing to telomere metabolism, but also, surprisingly, for 12 genes mutated in Fanconi anaemia. Furthermore, p53(Δ31/Δ31) fibroblasts exhibit a reduced capacity to repair DNA interstrand crosslinks, a typical feature of Fanconi anaemia cells. Importantly, the p53-dependent downregulation of Fanc genes is largely conserved in human cells. Defective DNA repair is known to activate p53, but our results indicate that, conversely, an increased p53 activity may attenuate the Fanconi anaemia DNA repair pathway, defining a positive regulatory feedback loop.

    2017-01-01

    We report a case of a previously well 46-year-old man who presented with microangiopathic haemolytic anaemia (MAHA) of unknown origin. After extensive investigations, he was diagnosed with cancer-related microangiopathic haemolytic anaemia (CR-MAHA) secondary to gastric adenocarcinoma. Initial treatment with plasmapheresis was ineffective, but the patient’s haematological abnormalities improved markedly with chemotherapy directed against his gastric cancer. Our case amplifies previous experience of gastric cancer-associated MAHA which responded to treatment with chemotherapy. We review current understanding of the proposed pathophysiology of CR-MAHA and conclude that this condition is ideally treated with chemotherapy.

    Megaloblastic anaemia and aplastic anaemia are important causes of pancytopenia in India. Since both may have presence of macrocytes, peripheral smear examination alone may pose a difficulty in distinction between the two in the absence of macro-ovalocytes and hypersegmented neutrophils. The present study was conducted to evaluate the role of red cell indices in differentiation between macrocytosis of aplastic anaemia and megaloblastic anaemia. Haemogram from 25 cases each of biopsy proven megaloblastic anaemia and aplastic anaemia were reviewed. It was observed that MCV was greater than 97 fl in 15 cases of aplastic anemia (mean MCV 109.7 fl), and 25 cases of megaloblastic anaemia (mean MCV 113.2 fl). Hb, MCV & MCHC were comparable in the two groups. However, mean RDW in megaloblastic anaemia (mean 87.7 fl) was significantly higher than those in aplastic anaemia (mean 71.4 fl). The difference in RDW of patients with megaloblastic anaemia and aplastic anaemia was statistically significant. We conclude that RDW can be of help to differentiate between the two conditions.

    Full Text Available Abstract Background The increased heterogeneity in the distribution of social and biological risk factors makes the epidemiology of anaemia a real challenge. A cross-sectional study was conducted at Kassala, Eastern Sudan during the period of January — March 2011 to investigate the prevalence and predictors of anaemia among adults (> 15 years old. Findings Out of 646, 234 (36.2% adults had anaemia; 68 (10.5%; 129 (20.0% and 37 (5.7% had mild, moderate and severe anaemia, respectively. In logistic regression analyses, age (OR = 1.0, CI = 0.9–1, P = 0.7, rural vs. urban residency (OR = 0.9, CI = 0.7–1.3, P = 0.9, female vs. male gender (OR = 0.8, CI = 0.6–1.1, P = 0.3, educational level ≥ secondary level vs. P = 0.8 and Hudandawa vs. non-Hudandawa ethnicity (OR = 0.8, CI = 0.6–1, P = 0.1 were not associated with anaemia. Conclusion There was a high prevalence of anaemia in this setting, anaemia affected adults regardless to their age, sex and educational level. Therefore, anaemia is needed to be screened for routinely and supplements have to be employed in this setting.

    Full Text Available New challenges and priorities are given in the EU Health programme 2007-2013. The objectives of the programme are to improve citizens’ health security, to promote health to improve prosperity and solidarity, and to generate and disseminate health knowledge. If challenges and priorities have been defined globally for rare diseases by the European Commission, persons involved in rare anaemias have taken the opportunity to contribute to the empowerment of patients with rare anaemias. One of the ENERCA partners objectives was the mapping of existing centres that take care of patients with rare anaemias in Europe. Another goal was to obtain a directory of facilities available per centre for patients with rare anaemias. We thought that with those results it could realistically help to define a consensus regarding the criteria to be recognised as a centre of expertise for haemoglobinopathies and very rare anaemias.

    Objective:To determin the extent to which parvovirus B19 (B19V) and co-infection of B19V and malaria contribute to risk of anaemia in children. Methods: B19V DNA and malaria parasites were screened for 234 children at the PML Children’s Hospital in Accra. The role of B19V and co-infection with B19V and malaria in anaemia was evaluated by analysing full blood cell counts, malaria and B19V DNA results from these children. Results: The prevalence of B19V, malaria and co-infection with B19V and malaria was 4.7%, 41.9%and 2.6%, respectively. Malaria posed a greater risk in the development of mild anaemia compared to severe anaemia (OR=5.28 vrs 3.15) whereas B19V posed a higher risk in the development of severe anaemia compared to mild anaemia (OR=4.07 vrs 1.00) from a non-anaemic child. Persons with co-infection with B19V and malaria had 2.23 times the risk (95%CI=0.40-12.54) of developing severe anaemia should they already have a mild anaemia. The degree of anaemia was about three times affected by co-infection (Pillai’s trace=0.551, P=0.001) as was affected by malaria alone (Pillai’s trace=0.185, P=0.001). B19V alone did not significantly affect the development of anaemia in a non-anaemic child. Microcytic anaemia was associated with B19V and co-infection with B19V and malaria more than normocytic normochromic anaemia. Conclusions: B19V was associated with malaria in cases of severe anaemia. The association posed a significant risk for exacerbation of anaemia in mild anaemic children. B19V and co-infection with B19V and malaria may be associated with microcytic anaemia rather than normocytic normochromic anaemia as seen in cases of B19V infection among persons with red cell abnormalities.

    2014-01-01

    Full Text Available Background: Sickle cell haemoglobin (HbS is the commonest abnormal haemoglobin and it has a worldwide distribution. Reports have shown that patients with sickle cell anaemia (HbSS have an increased susceptibility to infection leading to increased morbidity and mortality. Impaired leucocyte function and loss of both humoral and cell-mediated immunity are some of the mechanisms that have been reported to account for the immunocompromised state in patients with sickle cell disease. This study was carried out to determine the CD4+ T lymphocytes count in patients with sickle cell anaemia. Materials and Methods: A comparative cross-sectional study of 40 sickle cell anaemia patients in steady state (asymptomatic for at least 4 weeks attending haematology clinic and 40 age and sex-matched healthy HbA control were recruited into the study. Both HbS patients and the controls were HIV negative. The blood samples obtained were analyzed for CD4+ T cell by Flow cytometry. Results: The study found that there was no significant difference in the number of CD4+ T lymphocyte count between individuals with sickle cell anaemia and HbA (1016 ± 513 cells/μL vs 920 ± 364cells/μL. Conclusion: It is recommended that the functionality of CD4+ T lymphocyte should be considered rather than the number in further attempt to elucidate the cellular immune dysfunction in patients with sickle cell anaemia.

    2017-01-01

    Anaemia is a condition in which the number of red cells necessary to meet the body's physiological requirements is insufficient. Iron deficiency anaemia and the anaemia of chronic disease are the two most common causes of anaemia worldwide;(1) iron homeostasis plays a pivotal role in the pathogenesis of both diseases. An understanding of how iron studies can be used to distinguish between these diseases is therefore essential not only for diagnosis but also in guiding management. This review will primarily focus on iron deficiency anaemia and anaemia of chronic disease; however, iron overload in anaemia will also be briefly discussed.

    1995-07-01

    One hundred and two pregnant women and their neonates were examined to evaluate the effect of maternal haemoglobin concentration (Hb. conc) and iron deficiency anaemia on the placental weight and the foetal outcome. Haematological and serum ferritin values were determined. It was observed that 34.3% of the pregnant women were anaemic. Maternal Hb conc. and serum ferritin showed a highly significant correlation (r = 0.40, p < 0.001) indicating that iron deficiency was the most important cause of anaemia amongst them. The maternal Hb conc. showed a significant correlation with placental weight (p < 0.05), birth weight (p < 0.01), Apgar score (p < 0.001) and birth asphyxia. Maternal serum ferritin also correlated positively with cord ferritin (p < 0.001). The study did not reveal any association between high Hb and adverse foetal outcome.

    Full Text Available Anaemia is accepted amongst critically ill patients as an alternative to elective blood transfusion. This practice has been extrapolated to head injury patients with only one study comparing the effects of mild anaemia on neurological outcome. There are no studies quantifying microcirculation during anaemia. Experimental studies suggest that anaemia leads to cerebral hypoxia and increased rates of infarction, but the lack of clinical equipoise when testing the cerebral effects of transfusion amongst critically injured patients, supports the need of experimental studies. The aim of this study was to quantify cerebral microcirculation and the potential presence of axonal damage in an experimental model exposed to normovolaemic anaemia, with the intention of describing possible limitations within management practices in critically ill patients. Under non-recovered anaesthesia, six Merino sheep were instrumented using an intracardiac transeptal catheter to inject coded microspheres into the left atrium to ensure systemic and non-chaotic distribution. Cytometric analyses quantified cerebral microcirculation at specific regions of the brain. Amyloid precursor protein staining was used as an indicator of axonal damage. Animals were exposed to normovolaemic anaemia by blood extractions from the indwelling arterial catheter with simultaneous fluid replacement through a venous central catheter. Simultaneous data recording from cerebral tissue oxygenation, intracranial pressure and cardiac output was monitored. A regression model was used to examine the effects of anaemia on microcirculation with a mixed model to control for repeated measures. Homogeneous and normal cerebral microcirculation with no evidence of axonal damage was present in all cerebral regions, with no temporal variability, concluding that acute normovolaemic anaemia does not result in short term effects on cerebral microcirculation in the ovine brain.

    BACKGROUND: the impact of anaemia on the outcome after a hip fracture surgery is controversial, but anaemia can potentially decrease the physical performance and thereby impede post-operative rehabilitation. We therefore conducted a prospective study to establish whether anaemia affected functional...... was measured on each of the first three post-operative days, and anaemia defined as Hb ..., respectively. A significant association between anaemia and the ability to walk independently before the correction of anaemia was present on each of the 3 days separately (P

    One of the most fascinating areas of research within the field of histocompatibility at present time concerns an observation that a major human histocompatibility system, human leucocyte antigen (HLA), is deeply involved in the development of a great number of diseases. Major histocompatibility complex is the most polymorphic system in the genome of different species. Recognition of HLA alleles could be useful in transplantation and disease studies. Genetic construct of HLA DRB1 was studied in Iranian normal populations and patients with aplastic anaemia and Fanconi's disease. DNA was extracted from the whole blood of 466 normal, 35 aplastic anaemia and 10 Fanconi's individuals. Then DRB1 gene polymorphism was studied by polymerase chain reaction-sequence-specific primer method. The HLA DRB1 gene analysis showed increase of DRB1*07 in aplastic anaemia patients compared to normal population (P = 0.02). According to this study, the frequency of DRB1*07 in normal individuals was 8.3, and in aplastic anaemia patients, 15.7%. Additionally, the frequency of DRB1*04 in normal, aplastic anaemia and Fanconi's individuals was 10, 5.7 and 20%, respectively. Our results of investigation showed correlation between some HLA alleles with the studied diseases. We reported the frequency of various DR types in aplastic and Fanconi's patients. This study could imply the possible role of HLA-DRB1*07 in the incidence of aplastic anaemia. Moreover, the frequency of DRB1*04, DRB1*03 and DRB1*15 alleles showed intermediate correlation with Fanconi's anaemia.

    Full Text Available Anaemia is the most widespread nutrition problem in the world and has predominance in developing countries like India, particularly in children and women. The magnitude of anaemia has been well-documented in pregnant women and infants, but there is scarce data on the prevailing occurrence of anaemia in school children. The current study was undertaken to know the point prevalence of anaemia and the comparative effectiveness of twice a week iron supplementation program to daily supplementation program in enhancing the hemoglobin levels in children aged 10-14 years with different grades of anemia in high schools in and around Kakinada, East Godavari district, Andhra Pradesh. METHODS A total of 400 children in the age group of 10-14 years were included in this study from both government and private schools by random sampling. After estimating the point prevalence of anaemia by Sahli’s method all the children were given a single dose anti-helminthic and the children who were anaemic were further randomly divided into two subgroups A and B and allotted to either a daily or a twice weekly iron supplementation regimen respectively. The haemoglobin was again assessed after three months. RESULTS Point prevalence of anaemia among these children was 95.75%. Prevalence of anaemia was significantly higher amongst girls (97.8% as compared to boys (93.9%. Prevalence of anaemia was nearly equal in government (96% and private (95.5% schools. Mean improvement in Hb% of 2.23gm% and 1.98gm% was seen in daily and weekly twice iron groups respectively with no significant difference between two groups. Reduction in prevalence of anemia was 86% in daily iron and 80% in weekly twice iron regimen group. Daily iron group experienced more side effects (15.1% when compared to weekly twice iron group (8.1%. CONCLUSION This study shows that the point prevalence of anaemia in school children is high. Supervised iron and folic acid therapy twice a week is as effective as

    Anaemia is frequent in cancer and may increase tumour hypoxia that stimulates angiogenesis. However, erythropoietin is a hypoxia-inducible stimulator of erythropoiesis which seems to improve quality of life in cancer patients. Two recent phase III randomized studies showed negative results using erythropoietin in head and neck cancer patients and in metastatic breast cancer patients with impaired specific survival. In vitro and in vivo experiments have provided erythropoietin-receptor expression in endothelial cancer cells including malignant tumours of the breast, prostate, cervix, lung, head and neck, ovary, melanoma, stomach, gut, kidney etc. Biologic effect of erythropoietin and its receptor linkage induces proliferation of human breast cancer and angiogenesis and may limit anti-tumour effect of cancer treatment, in part, by tumour vascularization improvement. In addition, the use of exogenous erythropoietin could be able to favour tumour progression by improving tumour oxygenation and nutriment supply. If erythropoietin receptor were functional in human cancer. the assessment of erythropoietin receptor expression on tumour cell may help to select patients benefiting from exogenous erythropoietin. However. the relationship between erythropoietin receptor expression, tumour growth and exogenous erythropoietin. requires more studies. The results of recent clinical trials suggest that using erythropoietin should be avoided in non-anemic patients and discussed in patients receiving curative therapy. (authors)

    After casting doubt on malaria as the cause of death for Tutankhamun, the author points out that the hypothesis of homozygotic sickle-cell anaemia, or a double HbS/β₀thal heterozygosis, is hardly more credible. To have any chance of being valid, any such hypothesis would have to involve a combination of at least three rare factors: survival until the age of 19 of a subject with homozygotic sickle-cell anaemia, with a probability at birth as to a life expectancy of more than five years probably standing at less than 5%, and with, for all bone sequelae and anomalies, osteonecrosis whose location is characteristic, not of sickle-cell anaemia, but rather of a case of Freiberg-Kohler syndrome, which is also rare, but which is on the other hand fully compatible with the condition of the mummy's skeleton.

    Full Text Available BACKGROUND: Anaemia is the commonest global public health problem and especially harmful when the pregnancy is complicated by anaemia. Women in reproductive age group are more vulnerable for iron deficiency anaemia with an estimated prevalence of around 70 to 80% in pregnant women. MATERIAL AND METHODS: The aim of the study was to analyse the foetal outcome in the hospitalised pregnant women with severe anaemia. This is a prospective study carried out at maternity ward of Government G eneral H ospital, Kurnool of Andhra Pradesh, India over a period of one year from October 2007 to September 2008. RESULTS: Total of 9731 deliveries occurred during the study period, 282 (2.89 % were severely anaemic at the time of delivery. Majority of the women w ere of 20 - 24 years age (68.4% with second gravidas 37.5%, term gestation 52.1%, preterm deliveries 47.9%, lower socio - economic status 87.6% and Unbooked cases 67.4% and low birth weight in 53.2% cases, intra uterine growth retardation and intra uterine foetal death contributes to 12.8% and 16.7% cases respectively. A total of 36 (12.8% neonates required admission in neonatal intensive care unit and 16(5.7% of them died. CONCLUSION: Severe anaemia during pregnancy has adverse perinatal outcome in the fo rm of low birth weight, preterm birth, intrauterine growth retardation and intrauterine death. Regular iron supplementation during the antenatal period, management of anaemia and improving the nutritional status of the mother will improve the adverse neona tal outcome and decreases perinatal morbidity and mortality.

    1. Whole-body counting has been used to monitor the clearance of [57Co]cyanocobalamin in normal subjects, vegans and patients with pernicious anaemia. After oral administration of 57Co-labelled cyanocobalamin (1 microgram/1 muCi), subjects were counted for radioactivity monthly for a maximum period of 1 year. 2. The results obtained were consistent with a monoexponential clearance model and a least squares fit showed that there was no significant difference between the mean clearance rates for the vegans and normal subjects. 3. The patients with pernicious anaemia cleared the vitamin significantly more quickly than the normal control subjects. 4. This may be due to failure to reabsorb biliary vitamin B12 in pernicious anaemia because of the absence of intrinsic factor.

    Full Text Available Anemia is not a diagnosis; it is a manifestation of an underlying disorder. Thus, even mild, asymptomatic anemia should be investigated so that the primary problem can be diagnosed and treated. Laboratory evaluation begins with a CBC, including WBC and platelet counts, RBC indices and morphology (MCV, MCH, MCHC, RBC distribution width [RDW], and examination of the peripheral smear. In many instances routine test like Hb, TLC, DLC, GBP fail to decide anemia especially in early cases and also fail to decide the type of anaemia. In such situations the RBC indices and RDW are very useful. These become abnormal even before changes in routine hemogram are appreciable. Thalassemia minor poses problems in diagnosis because GBP reveals no features of hemolysis rather it has microcytic hypochromic picture which has similarity with iron deficiency anemia. It is difficult to differentiate between two by only GBP. Several decision making rules have been proposed for differentiation. METHOD : The present study was carried out in 100 cases to evaluate anaemia in different age groups based on RBC Indices and RDW and t o evaluate sensitivity of RBC indices and RDW in diagnosis of anaemia. Cases showing positivity by various rules and RDW in favour of thalassemia minor were subjected to Hb electrophoresis for confirmation of diagnosis. RESULTS : RBC indices are more sensitive for diagnosis of microcytic hypochromic anemia, normocytic normochromic anemia and macrocytic anemia than PBS alone. RDW - CV is superior to all in use to differentiate iron deficiency anemia an d thalassemia minor having high sensitivity 87.3% and specificity 90 .5%.

    Full Text Available The objective was to develop a non-terminal, acute normovolaemic anaemia model in dogs that has minimal effects on patient well-being. Eleven normal Beagle dogs were used. About 20 % of the circulating blood volume was removed from the jugular vein 1-3 times per day over a 3-4 day period until a haematocrit (Ht of 13-17 % was obtained. Normovolaemia was maintained by replacing the volume deficit of the red blood cells with Ringer's lactate and re-infusing the plasma. Full blood count and Ht were monitored twice daily. The 13-17 % Ht was reached within 3-4 days with the number of phlebotomies ranging from four to seven. The model was primarily developed to determine echocardiographic values as well as Doppler abdominal splanchnic blood flow parameters in anaemic dogs as part of a study that will compare these results to similar studies in babesiosis-induced anaemia. The model may also be useful in the evaluation of the pathophysiology of anaemia in dogs or as a model for anaemia in humans.

    Autoimmune hemolytic anaemia is a rare presentation of Hodgkin's lymphoma though its association with Non- Hodgkin's lymphoma is well known. It is usually detected at the time of diagnosis when it accompanies Hodgkin's and rarely precedes it. It is a warm immune hemolytic anemia which is responsive to steroids and rituximab. We hereby report a case of advanced Hodgkin's disease who presented as AIHA.

    Results: Males were 154 and females were 146. Degree of anaemia was severe in females when compared to males. Of 52 cases subjected for electrophoresis 36 were homozygous, 15 were heterozygous and 1 case Sickle thalassemia. 7 cases showed HbF above 5%. Conclusions: Most of the patients were under 40 yrs suggesting decreased survival after that age. An increased level of HbF was associated with better prognosis suggesting the need to target at drugs which increase HbF. [Int J Res Med Sci 2016; 4(1.000: 246-251

    Conor P Doherty

    Full Text Available BACKGROUND: Iron supplementation is employed to treat post-malarial anaemia in environments where iron deficiency is common. Malaria induces an intense inflammatory reaction that stalls reticulo-endothelial macrophagal iron recycling from haemolysed red blood cells and inhibits oral iron absorption, but the magnitude and duration of these effects are unclear. METHODOLOGY/PRINCIPAL FINDINGS: We examined the red blood cell incorporation of oral administered stable isotopes of iron and compared incorporation between age matched 18 to 36 months old children with either anaemia post-malaria (n = 37 or presumed iron deficiency anaemia alone (n = 36. All children were supplemented for 30 days with 2 mg/kg elemental iron as liquid iron sulphate and administered (57Fe and (58Fe on days 1 and 15 of supplementation respectively. (57Fe and(58Fe incorporation were significantly reduced (8% vs. 28%: p<0.001 and 14% vs. 26%: p = 0.045 in the malaria vs. non-malaria groups. There was a significantly greater haemoglobin response in the malaria group at both day 15 (p = 0.001 and 30 (p<0.000 with a regression analysis estimated greater change in haemoglobin of 7.2 g/l (s.e. 2.0 and 10.1 g/l (s.e. 2.5 respectively. CONCLUSION/SIGNIFICANCE: Post-malaria anaemia is associated with a better haemoglobin recovery despite a significant depressant effect on oral iron incorporation which may indicate that early erythropoetic iron need is met by iron recycling rather than oral iron. Supplemental iron administration is of questionable utility within 2 weeks of clinical malaria in children with mild or moderate anaemia.

    Lenalidomide (Revlimid(®)), a thalidomide analogue, is an orally administered second generation immunomodulator with anti-angiogenic, antineoplastic, anti-inflammatory and pro-erythropoietic properties. It is approved for the treatment of patients with transfusion-dependent anaemia due to International Prognostic Scoring System low- or intermediate-1-risk myelodysplastic syndrome (MDS) associated with either chromosome 5q deletion [del(5q)] with or without additional cytogenetic abnormalities (US, Japan and Switzerland etc.), or with an isolated del(5q) cytogenetic abnormality when other therapeutic options are insufficient or inadequate (EU) [featured indication]. In a randomized, double-blind, multicentre, registrational trial (MDS-004; n = 205) in this patient population, a significantly higher proportion of lenalidomide recipients than placebo recipients achieved red blood cell transfusion independence for ≥26 consecutive weeks (primary endpoint for efficacy) and cytogenetic responses. The erythroid response to lenalidomide was accompanied by an increase in the haemoglobin levels. These efficacy outcomes are generally consistent with those seen in an earlier noncomparative registrational trial (MDS-003; n = 148). In MDS-004, lenalidomide also significantly improved health-related quality of life compared with placebo at 12 weeks. Retrospective analyses that compared outcomes between lenalidomide-treated patients with low- or intermediate-1-risk del(5q) MDS and multicentre registry cohorts showed that lenalidomide treatment did not appear to increase the risk of progression to acute myeloid leukaemia. Lenalidomide had a manageable safety profile in the registrational trials, with ≤20 % of patients discontinuing treatment because of adverse events. The most common adverse events (incidence ≥20 %) occurring in lenalidomide recipients were thrombocytopenia and neutropenia, which were generally managed by dosage reductions and/or interruptions, and

    Full Text Available BACKGROUND Anaemia is a nutritional problem worldwide and its prevalence is higher in developing countries when compared to the developed countries. Anaemia, a manifestation of under-nutrition and poor dietary intake of iron is a public health problem, not only among pregnant women, infants and young children, but also among adolescents. Recent studies on the prevalence of anaemia have been conducted on preschool children only, so there is a need for more studies related to anaemia among school children. The present study was done to estimate the prevalence of anaemia among school children aged 10-15 years from Guntur, Andhra Pradesh. MATERIALS AND METHODS A cross-sectional study was conducted among 500 school children aged 10 to 15 years. Purposive sampling was used to include 250 boys and 250 girls. Haemoglobin estimation was done by cyanmethaemoglobin method. The severity of anaemia was classified on the basis of WHO criteria into Mild, Moderate and Severe. Data analysis was done by SPSS version 21. RESULTS The overall prevalence of anaemia was 27.4% in the present study. A higher prevalence of anaemia was observed among girls (42.4% than boys (12.4%. The prevalence of mild anaemia was 34.4% and 9.6% among girls and boys respectively. CONCLUSION The prevalence of anaemia is high among school going adolescents. Special emphasis should be given on nutritional supplementation with iron and health education for this age group.

    Full Text Available BACKGROUND AND OBJECTIVES: Hookworm infection is among the major causes of anaemia in poor communities, but its importance in causing maternal anaemia is poorly understood, and this has hampered effective lobbying for the inclusion of anthelmintic treatment in maternal health packages. We sought to review existing evidence on the role of hookworm as a risk factor for anaemia among pregnant women. We also estimate the number of hookworm infections in pregnant women in sub-Saharan Africa (SSA. METHODS: Structured searches using MEDLINE and EMBASE as well as manual searches of reference lists were conducted, and unpublished data were obtained by contacting authors. Papers were independently reviewed by two authors, and relevant data were extracted. We compared haemoglobin concentration (Hb according to intensity of hookworm infection and calculated standardised mean differences and 95% confidence intervals. To estimate the number of pregnant women, we used population surfaces and a spatial model of hookworm prevalence. FINDINGS: One hundred and five reports were screened and 19 were eligible for inclusion: 13 cross-sectional studies, 2 randomised controlled trials, 2 non-randomised treatment trials and 2 observational studies. Comparing uninfected women and women lightly (1-1,999 eggs/gram [epg] infected with hookworm, the standardised mean difference (SMD was -0.24 (95% CI: -0.36 to -0.13. The SMD between women heavily (4000+ epg infected and those lightly infected was -0.57 (95% CI: -0.87 to -0.26. All identified intervention studies showed a benefit of deworming for maternal or child health, but since a variety of outcomes measures were employed, quantitative evaluation was not possible. We estimate that 37.7 million women of reproductive age in SSA are infected with hookworm in 2005 and that approximately 6.9 million pregnant women are infected. CONCLUSIONS: Evidence indicates that increasing hookworm infection intensity is associated with

    Skin involvement with dermal fibrosis is a hallmark of systemic sclerosis (SSc), and keratinocytes may be critical regulators of fibroblast function through secretion of chemo-attracting agents, as well as through growth factors and cytokines influencing the phenotype and proliferation rate of fibroblasts. Epithelial-fibroblast interactions have an important role in fibrosis in general. We have characterized the SSc epidermis and asked whether SSc-injured epidermal cells release factors capable of promoting fibrosis. Our results show that the SSc epidermis is hypertrophic, and has altered expression of terminal differentiation markers involucrin, loricrin, and filaggrin. Multiplex profiling revealed that SSc epidermal explants release increased levels of CCN2 and S100A9. CCN2 induction was found to spread into the upper papillary dermis, whereas S100A9 was shown to induce fibroblast proliferation and to enhance fibroblast CCN2 expression via Toll-like receptor 4. These data suggest that the SSc epidermis provides an important source of pro-fibrotic CCN2 and proinflammatory S100A9 in SSc skin, and therefore contributes to the fibrosis and inflammation seen in the disease.

  11. Mechanisms controlling anaemia in Trypanosoma congolense infected mice.

    Directory of Open Access Journals (Sweden)

    Harry A Noyes

    Full Text Available BACKGROUND: Trypanosoma congolense are extracellular protozoan parasites of the blood stream of artiodactyls and are one of the main constraints on cattle production in Africa. In cattle, anaemia is the key feature of disease and persists after parasitaemia has declined to low or undetectable levels, but treatment to clear the parasites usually resolves the anaemia. METHODOLOGY/PRINCIPAL FINDINGS: The progress of anaemia after Trypanosoma congolense infection was followed in three mouse strains. Anaemia developed rapidly in all three strains until the peak of the first wave of parasitaemia. This was followed by a second phase, characterized by slower progress to severe anaemia in C57BL/6, by slow recovery in surviving A/J and a rapid recovery in BALB/c. There was no association between parasitaemia and severity of anaemia. Furthermore, functional T lymphocytes are not required for the induction of anaemia, since suppression of T cell activity with Cyclosporin A had neither an effect on the course of infection nor on anaemia. Expression of genes involved in erythropoiesis and iron metabolism was followed in spleen, liver and kidney tissues in the three strains of mice using microarrays. There was no evidence for a response to erythropoietin, consistent with anaemia of chronic disease, which is erythropoietin insensitive. However, the expression of transcription factors and genes involved in erythropoiesis and haemolysis did correlate with the expression of the inflammatory cytokines Il6 and Ifng. CONCLUSIONS/SIGNIFICANCE: The innate immune response appears to be the major contributor to the inflammation associated with anaemia since suppression of T cells with CsA had no observable effect. Several transcription factors regulating haematopoiesis, Tal1, Gata1, Zfpm1 and Klf1 were expressed at consistently lower levels in C57BL/6 mice suggesting that these mice have a lower haematopoietic capacity and therefore less ability to recover from

    Full Text Available Abstract Background A Phase 1-2b study of the blood stage malaria vaccine AMA1-C1/Alhydrogel was conducted in 336 children in Donéguébougou and Bancoumana, Mali. In the Phase 2 portion of the study (n = 300, no impact on parasite density or clinical malaria was seen; however, children who received the study vaccine had a higher frequency of anaemia (defined as haemoglobin Methods To further investigate the possible impact of vaccination on anaemia, additional analyses were conducted including patients from the Phase 1 portion of the study and controlling for baseline haemoglobin, haemoglobin types S or C, alpha-thalassaemia, G6PD deficiency, and age. A multiplicative intensity model was used, which generalizes Cox regression to allow for multiple events. Frailty effects for each subject were used to account for correlation of multiple anaemia events within the same subject. Intensity rates were calculated with reference to calendar time instead of time after randomization in order to account for staggered enrollment and seasonal effects of malaria incidence. Associations of anaemia with anti-AMA1 antibody were further explored using a similar analysis. Results A strong effect of vaccine on the incidence of anaemia (risk ratio [AMA1-C1 to comparator (Hiberix]= 2.01, 95% confidence interval [1.26,3.20] was demonstrated even after adjusting for baseline haemoglobin, haemoglobinopathies, and age, and using more sophisticated statistical models. Anti-AMA1 antibody levels were not associated with this effect. Conclusions While these additional analyses show a robust effect of vaccination on anaemia, this is an intensive exploration of secondary results and should, therefore, be interpreted with caution. Possible mechanisms of the apparent adverse effect on haemoglobin of vaccination with AMA1-C1/Alhydrogel and implications for blood stage vaccine development are discussed. The potential impact on malaria-associated anaemia should be closely

    Full Text Available Abstract Background Anaemia is the most common haematological complication of HIV and associated with a high morbidity and a poor prognosis. The pathogenesis of HIV-associated anaemia is poorly understood and may include a direct effect of HIV on erythropoiesis. In vitro studies have suggested that specific HIV strains, like X4 that uses the CXCR4 co-receptor present on erythroid precursors, are associated with diminished erythropoiesis. This co-receptor affinity is determined by changes in the hypervariable loop of the HIV-1 envelope genome. In a previous case-control study we observed an association between HIV and severe anaemia in Malawian children that could not be fully explained by secondary infections and micronutrient deficiencies alone. We therefore explored the possibility that alterations in the V1-V2-V3 fragment of HIV-1 were associated with severe anaemia. Methods Using peripheral blood nucleic acid isolates of HIV-infected children identified in the previous studied we assessed if variability of the V1-V2-V3 region of HIV and the occurrence of X4 strains were more common in HIV-infected children with (cases, n = 29 and without severe anaemia (controls, n = 30. For 15 cases bone marrow isolates were available to compare against peripheral blood. All children were followed for 18 months after recruitment. Results Phylogenetic analysis showed that HIV-1 subtype C was present in all but one child. All V1-V2-V3 characteristics tested: V3 charge, V1-V2 length and potential glycosylation sites, were not found to be different between cases and controls. Using a computer model (C-PSSM four children (7.8% were identified to have an X4 strain. This prevalence was not different between study groups (p = 1.00. The V3 loop characteristics for bone marrow and peripheral blood isolates in the case group were identical. None of the children identified as having an X4 strain developed a (new episode of severe anaemia during follow up. Conclusion

The subjects were 108 consecutive pregnant women aged 18 to 44 years recruited from the antenatal clinics. 23 (21.3%) had malaria, 35 (32.4%) had anaemia while 20(18.5%) had both malaria and anaemia. The highest incidence of malaria occurred in the second trimester, while anaemia was most prevalent in the third trimester (62.86%) and among primigravidae (37.14%). All the cases of malaria were due to plasmodium falciparum. Six out of the 20 women with both anemia and malaria were admitted and treated. Two low birth weight babies were delivered among the malaria and anaemia group. The incidence rates of malaria and anaemia were 215 and 327 per 1000 pregnant women respectively while the incidence rate of anaemia due to malaria was 571 per 1000 infected pregnant women. There is a need for a more effective intervention to reduce the incidence of both malaria and anaemia in pregnancy.

    Full Text Available Introduction: The prevalence of anaemia among children less than five years of age in India is around 70%. Anaemia in young children puts them at a higher risk of experiencing health problems such as stunted growth, mental retardation, and increased susceptibility to infectious diseases. The present study was undertaken to evaluate the effectiveness of IFA supplementation (daily vs. biweekly vs. weekly regime on haemoglobin levels of young children. Materials and Methods: A total 740 children in age group of six months to five years were included in this community based interventional study using Systemic random sampling. The children having mild to moderate anaemia were then divided into three groups A, B and C by simple random sampling and were given Iron and Folic acid supplementation daily, biweekly and weekly respectively. Follow up data was collected after 3 months and analysed using appropriate tests. Results: Prevalence of Anaemia was 91.1% among study participants. Comparison after 3 months showed significant change in haemoglobin levels in all three groups with mean improvement of 1.31 gm%, 0.89 gm% and 0.85 gm% in group A, B and C respectively. However, no significant difference was noted among the groups in pre as well as post intervention phase. Conclusion: Weekly regime is as effective as daily or biweekly regime in improving haemoglobin levels in children. Moreover, it has better compliance, lesser side effects and cost of therapy. So, the same should be recommended for prophylaxis as well as treatment of mild to moderate anaemia cases. [Natl J Med Res 2014; 4(1.000: 33-36

    The Fanconi anaemia pathway repairs DNA interstrand crosslinks (ICLs) in the genome. Our understanding of this complex pathway is still evolving, as new components continue to be identified and new biochemical systems are used to elucidate the molecular steps of repair. The Fanconi anaemia pathway uses components of other known DNA repair processes to achieve proper repair of ICLs. Moreover, Fanconi anaemia proteins have functions in genome maintenance beyond their canonical roles of repairing ICLs. Such functions include the stabilization of replication forks and the regulation of cytokinesis. Thus, Fanconi anaemia proteins are emerging as master regulators of genomic integrity that coordinate several repair processes. Here, we summarize our current understanding of the functions of the Fanconi anaemia pathway in ICL repair, together with an overview of its connections with other repair pathways and its emerging roles in genome maintenance.

  18. Iron in haemoglobinopathies and rare anaemias

    Full Text Available Iron overload in haemoglobinopathies and rare anaemias may develop from increased iron absorption secondary to hepcidin suppression, and/or from repeated blood transfusions. While the accumulation of body iron load from blood transfusion is inevitable and predictable from the variable rates of transfusion in the different conditions, there are some important differences in the distribution of iron overload and its consequences between these. Transfusion-dependent thalassaemia (TDT is the best described condition in which transfusional overload occurs. Initially iron loads into macrophages, subsquently hepatocytes, and then the endocrine system including the anterior pituiatry and finally the myocardium. The propensity to extrahepatic iron spread increases with rapid transfusion and with inadequate chelation therapy but there is considerable interpatient and interpopulation variability in this tendency. The conduits though which iron is delivered to tissues is through non transferrin iron species (NTBI which are taken into liver, endocrine tissues and myocardium through L-type calcium channells and possibly through other channells. Recent work by the MSCIO group1 suggests that levels of NTBI are determined by three mechanisms: i increasing with iron overload; ii increasing with ineffective erythropoieis; iii and decreasing when level of transferrin iron utilisation is high. In TDT all three mechanisms increase NTBI levels because transferrin iron utilisation is suppressed by hypertransfusion. It is hypothesized that the transfusion regimen and target mean Hb may have a key impact on NTBI levels because high transfusion regimes may suppress the ‘sink’ effect of the erythron though decreased clearance of transferrin iron. In sickle cell disease (SCD without blood transfusion the anaemia results mainly from haemolysis rather than from ineffective erythropoiesis.2 Thus there is a tendency to iron depletion because of urinary iron loss from

    Anaemia due to iron deficiency is still a widespread problem. Among adolescent girls, it will bring negative consequences on growth, school performance, morbidity and reproductive performance. This cross sectional study aimed to identify the different nutritional and iron status characteristics of young adolescent girls 10-12 years old with iron deficiency anaemia and anaemia without iron deficiency in the rural coastal area of Indonesia. Anaemic girls (N =133) were recruited out of 1358 girls from 34 elementary schools. Haemoglobin, serum ferritin, serum transferrin receptor and zinc protophorphyrin were determined for iron status, whilst weight and height were measured for their nutritional status. General characteristics and dietary intake were assessed through interview. Out of 133 anaemic subjects, 29 (21.8%) suffered from iron deficiency anaemia, which was not significantly related to age and menarche. About 50% were underweight and stunted indicating the presence of acute and chronic malnutrition. The proportion of thinness was significantly higher (P < 0.05) among subjects who suffered from iron deficiency anaemia (51.7% vs. 29.8%). Furthermore, thin subjects had a 5 fold higher risk of suffering from iron deficiency anaemia (P< 0.05) than non-thin subjects (OR: 5.1; 95%CI 1.34-19.00). Further study was recommended to explore other factors associated with anaemia and iron deficiency anaemia, such as the thalassemia trait and vitamin A deficiency. The current iron-folate supplementation program for pregnant women should be expanded to adolescent girls.

    Full Text Available Abstract Background Anaemia is a common manifestation of paediatric HIV infection. Although there are many causes, anaemia of chronic diseases is the most frequent type. In poor countries iron deficiency is widespread. It is probable that many HIV-infected children in these countries are also iron deficient. This study describes the relationship between paediatric HIV infection and anaemia, and documents the peripheral iron status of antiretroviral naive, HIV-infected children. Methods Sixty children were evaluated prospectively. Investigations included CD4+ count, haemoglobin concentration (Hb, red blood cell (RBC morphology, and iron studies. Results Anaemia was present in 73% of children. Compared to mild HIV infection, median Hb was lower in children with moderate clinical infection (104 g/L v 112 g/L, p = 0.04 and severe clinical infection (96 g/L v 112 g/L, p = 0.006, and more children with severe infection were anaemic (92% v 58%, 0.04. There was a significant relationship between immunological status and Hb. 68% had abnormal RBC morphology. Significantly more children with moderate and severe disease, and severe immunosuppression had abnormal RBC morphology. 52% were iron-depleted, 20% had iron-deficient erythropoiesis and 18% iron deficiency anaemia (IDA. 16% (7/44 of anaemic children had microcytosis and hypochromia. Median soluble transferrin receptor concentration was significantly higher in those with microcytic hypochromic anaemia (42.0 nmol/L v 30.0 nmol/L, p = 0.008. Conclusions Both the proportion of anaemic children and the median Hb were associated with disease status. Iron depletion and IDA are major problems in HIV-infected children in South Africa.

    Full Text Available Abstract Introduction Unexplained anaemia is a rare mode of presentation for prolactinoma. We describe a case of a man, with chronic anaemia ascribed to old age. Six years later, he was evaluated and diagnosed with a prolactinoma and resultant osteoporosis. Prolactinoma in old people may present insidiously with chronic anaemia and osteoporosis with or without sexual dysfunction. Case presentation We describe the case of a 70-year-old Caucasian man who presented with mild anaemia and tiredness. His anaemia was investigated and ascribed to senescence. Endocrine causes were not considered or tested for. Six years later, he was again referred. Reassessment and direct questioning revealed long-standing sexual dysfunction. It was also discovered that our patient had fractured his radius twice, with minor trauma, during the preceding year. His serum prolactin was massively increased and a magnetic resonance imaging (MRI scan of the head demonstrated a pituitary mass consistent with a prolactinoma. Dual X-ray absorptiometry revealed osteoporosis. Treatment of the prolactinoma led to a reduction in his serum prolactin with a rise in his haemoglobin to normal levels. This suggested that the prolactinoma was present during the initial presentation and was the cause of his anaemia. Conclusion This case highlights the importance of fully evaluating and investigating unexplained anaemia in older people and that endocrine causes should be considered. Osteoporosis also requires evaluation with secondary causes considered.

    Objective:To assess the role of oxidative stress on anaemia in pregnancy.Methods:Blood samples were collected from pregnant and non-pregnant women who came for antenatal clinic and medical check at Comprehensive Health Center, Akungba-Akoko and Iwaro General Hospital in Akoko Area of Ondo State, Nigeria. Thick and thin blood films were prepared and used for malaria parasite counts. Haemoglobin level was determined by colorimetric method using Drabkin's solution. Oxidative status was determined using malondiadelhyde level as an indicator of lipid peroxidation, while ascorbic acid and reduced glutathione levels were measured by standard spectrophotometric methods.Results: Mean parasite density was significantly higher in pregnant women than non-pregnant women (P<0.05). Haemoglobin level was significantly reduced in malaria positive pregnant and non-pregnant women than malaria negative (8.3-10.0 g/dL) (P<0.05). The oxidative status indicated that malondialdehyde(MDA) was significantly increased in pregnant [(2.5±0.7) nmol/mL] than non-pregnant women [(1.8±0.1) nmol/mL] (P<0.05), while Vit C and superoxide dismutase(SOD) levels were significantly reduced in pregnant than non-pregnant women(P<0.05). There was an inverse correlation between Hb and MDA levels in pregnant women studied. Positive correlation was observed between the mean MDA level and parasite density (r = 0.53). The Hb level decreased as the parasite density and MDA level increased in pregnant women.Conclusions:This study shows that oxidative stress, caused by malaria infection could be part of the contributing factors responsible for anaemia in pregnancy.

    Fanconi's anaemia (FA) is an autosomal recessive disorder that is clinically characterized by aplastic anaemia, congenital malformations of the renal, cardiac, skeletal and skin structures, and an increased predisposition to malignancies. Patients with FA often present with bleeding and infection, which are symptoms related to thrombocytopenia and neutropenia. There are few reports of the oral manifestations of FA. We describe oral aphthous ulcerations in two siblings with FA. There was a rapid improvement and healing of ulcers after blood transfusions and increased haemoglobin levels. This may support the role of severe anaemia in oral ulcerations.

    Nutritional deficiency anaemia in vegans is common and usually due to lack of vitamin B12, as this vitamin is found almost exclusively in animal-based food products. In this case report we present a 39-year-old male vegan with severe macrocytic anaemia due to vitamin B12 deficiency as well as secondary hyperparathyroidism due to severe vitamin D deficiency. We want to emphasize the importance of a detailed nutritional history for patients with anaemia, and the need for vitamin B12 and vitamin D supplements for people who comply with a vegan diet.

    Full Text Available In India, although major cause of anaemia is said to be nutritional deficiencies which can be treated by medications, haemoglobinopathies are the most common inherited red cell disorders causing anaemia world-wide. Most clinically significant haemoglobinopathies are inherited defects of the globin chain of adult haemoglobin. Identification of these disorders is immensely important epidemiologically and for prevention of thalassaemias, sickle cell anaemia and other clinically severe haemoglobinopathies. OBJECTIVES The aim of this study was to determine the prevalence of thalassaemias, sickle cell and other haemoglobinopathies in patients of a tertiary care hospital of Jharkhand. MATERIALS AND METHODS A prospective study was undertaken in which 1048 cases were included over a period of 3 years {From October 2012 to Sept 2015} for patient referred from outpatient and inpatient department of tertiary medical care hospital for anaemia. Clinical history and family history were obtained from each patient. The venous blood samples were analysed for complete blood count and HighPerformance Liquid Chromatography (HPLC was performed on the samples with Bio-Rad Variant II. RESULTS Normal haemoglobin (Hb pattern was observed in 444 (42.5% cases and abnormalities were detected in 600 (57.5% patients. β (beta thalassaemia trait was the most common abnormality found in 156 (14.9% patients. Sickle cell disease in 128 (12.2% patients, HbSβ in 128 (12.26% patients, β thalassaemia major/intermedia in 112 (10.7% cases, Sickle cell trait in 55 (5.2% cases. Other variants detected included HbE, HbD-Punjab, HbD-Punjab trait, double heterozygous state of HbE and β-thalassaemia HbE, double heterozygous state of HbS and HbD-Punjab and HbJ-Meerut. CONCLUSION Premarital and antenatal screenings are important measures to prevent birth of children with severe Hb disorders. HPLC is a rapid and reliable technique for identification of various Hb fractions.

    The generation of induced pluripotent stem (iPS) cells has enabled the derivation of patient-specific pluripotent cells and provided valuable experimental platforms to model human disease. Patient-specific iPS cells are also thought to hold great therapeutic potential, although direct evidence for this is still lacking. Here we show that, on correction of the genetic defect, somatic cells from Fanconi anaemia patients can be reprogrammed to pluripotency to generate patient-specific iPS cells....

    The prevalence of anaemia is increasing globally. It has a close association with perioperative blood transfusion which, in turn, results in an increased risk of postoperative complications. Undesirable effects are not only limited to short-term, but also have long-term implications. Despite this, many patients undergo cardiac surgery with undiagnosed and untreated anaemia. We designed a retrospective, observational study to estimate the prevalence of anaemia in patients having cardiac surgery in Auckland District Health Board, blood transfusion rates and associated clinical outcome. Two hundred of seven hundred and twelve (28.1%) patients were anaemic. Red blood cell (RBC) transfusion rates were significantly higher in the anaemic group compared to the non-anaemic group (160 (80%) vs. 192 (38%), p-value Anaemia was significantly associated with the development of new infection (14 (7%) vs. 15 (2.9%), p-value 0.0193, RR (CI 95%) 2.389 (1.175-4.859)), prolonged ventilation time (47.01 hours vs. 23.59 hours, p-value 0.0076) and prolonged intensive care unit (ICU) stay (80.23 hours vs. 50.27, p-value 0.0011). Preoperative anaemia is highly prevalent and showed a clear link with significantly higher transfusion rates and postoperative morbidity. It is vital that a preoperative management plan for the correction of anaemia should be sought to improve patient safety and outcome.

  10. Scientific Opinion on infectious salmon anaemia (ISA

    EFSA Panel on Animal Health and Welfare (AHAW

    2012-11-01

    Full Text Available Atlantic salmon is the only species in which the disease infectious salmon anaemia (ISA has been observed naturally. Initial reports of findings of infectious salmon anaemia virus (ISAV before 2002, did not distinguish between non virulent HPR0 and virulent HPRΔ viruses, thus making interpretation of older findings difficult in the light of current knowledge. Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the relationship between HPR0 and HPRΔ, the risk of HPRΔ ISAV emerging from HPR0 ISAV, and possible risk factors for such an emergence. HPR0 ISAV does not cause clinical disease in Atlantic salmon; however, it causes a transient subclinical infection and replicates mainly in gills. There is no evidence for HPR0 ISAV leading to natural infection and replication in fish species other than Atlantic salmon. Virulent ISAV have deletions in the HPR region of the HE gene and they have either an insertion or the Q266L mutation in the F gene. The most plausible hypothesis is that virulent ISAV (HPRΔ is derived from HPR0 ISAV. This is further supported by the close association between the genetic relatedness and spatio-temporal distances of virus strains in solitary outbreaks. Epidemiological and historical data from solitary disease outbreaks indicates that the risk of HPRΔ ISAV emerging from HPR0 is low, but not negligible. The risk factors for HPRΔ emergence from HPR0 are unknown. Nevertheless, any factor that affects virus replication or host susceptibility could possibly influence the risk of emergence. More research is needed on the drivers for transition from HPR0 to HPRΔ and factors affecting host susceptibility and thereby emergence of clinical disease. A quantitative assessment of the different evolutionary forces for ISA would be useful, as well as the prevalence of ISAV HPR0 in farmed and wild Atlantic salmon.

    Full Text Available Abstract. The aim of the investigation was to study the immunological characteristics of RA patients with anaemia. Clinical and laboratory data including the percentage of the main lymphocyte subclasses, phagocyte and DTH-effector activity, serum concentration of immunoglobulins, the percentage of cells producing IFNγ and/or IL-4 and percent of monocytes producing TNF. We revealed some significant clinical, laboratory and immunological differences between RA patients and healthy donors and between patients with and without anaemia. Our data demonstrate RA anemic patients to have more severe disorders than patients without anaemia. We also revealed some significant immunological differences between RA patients and healthy donors and between patients with and without anaemia, including percent of cells producing IFNγ and/or IL-4. Our data permit to conclude that RA patients have many different immunological disturbances, more severe in anaemic patients.

    2008-12-01

    Full Text Available Abstract Background Guidelines for the management of anaemia in patients with chronic kidney disease (CKD recommend a minimal haemoglobin (Hb target of 11 g/dL. Recent surveys indicate that this requirement is not met in many patients in Europe. In most studies, Hb is only assessed over a short-term period. The aim of this study was to examine the control of anaemia over a continuous long-term period in Switzerland. Methods A prospective multi-centre observational study was conducted in dialysed patients treated with recombinant human epoetin (EPO beta, over a one-year follow-up period, with monthly assessments of anaemia parameters. Results Three hundred and fifty patients from 27 centres, representing 14% of the dialysis population in Switzerland, were included. Mean Hb was 11.9 ± 1.0 g/dL, and remained stable over time. Eighty-five % of the patients achieved mean Hb ≥ 11 g/dL. Mean EPO dose was 155 ± 118 IU/kg/week, being delivered mostly by subcutaneous route (64–71%. Mean serum ferritin and transferrin saturation were 435 ± 253 μg/L and 30 ± 11%, respectively. At month 12, adequate iron stores were found in 72.5% of patients, whereas absolute and functional iron deficiencies were observed in only 5.1% and 17.8%, respectively. Multivariate analysis showed that diabetes unexpectedly influenced Hb towards higher levels (12.1 ± 0.9 g/dL; p = 0.02. One year survival was significantly higher in patients with Hb ≥ 11 g/dL than in those with Hb Conclusion In comparison to European studies of reference, this survey shows a remarkable and continuous control of anaemia in Swiss dialysis centres. These results were reached through moderately high EPO doses, mostly given subcutaneously, and careful iron therapy management.

Objective: To assess the prevalence of anaemia among rural pre-school (1-5-years children of Maharashtra. Methods: A community based cross-sectional study was carried by National Nutrition Monitoring Bureau (NNMB covering a total of 404 (Boys-243; Girls-161 pre-school children. Information of socio-demographic particulars was obtained and the finger prick blood samples were collected for the estimation of haemoglobin levels by cyanmethmoglobin method. Results: The result shows that 59.2 % (CI: 54.4-64.0 of the rural pre-school children of Maharashtra were anaemic, and the prevalence was significantly (p40% among rural pre-school children of Maharashtra. Therefore, appropriate intervention measures such as supplementary iron & folic acid, periodic deworming and health & nutrition education should be strengthened. The community needs to be encouraged to diversify their diets by consuming iron rich foods.

    Diamond Blackfan anaemia (DBA) is a severe congenital failure of erythropoiesis. Despite mutations in one of several ribosome protein genes, including RPS19, the cause of the erythroid specificity is still a mystery. We hypothesized that, because the chromatin of late erythroid cells becomes condensed and transcriptionally inactive prior to enucleation, the rapidly proliferating immature cells require very high ribosome synthetic rates. RNA biogenesis was measured in primary mouse fetal liver erythroid progenitor cells; during the first 24 h, cell number increased three to fourfold while, remarkably, RNA content increased sixfold, suggesting an accumulation of an excess of ribosomes during early erythropoiesis. Retrovirus infected siRNA RPS19 knockdown cells showed reduced proliferation but normal differentiation, and cell cycle analysis showed a G1/S phase delay. p53 protein was increased in the knockdown cells, and the mRNA level for p21, a transcriptional target of p53, was increased. Furthermore, we show that RPS19 knockdown decreased MYB protein, and Kit mRNA was reduced, as was the amount of cell surface KIT protein. Thus, in this small hairpin RNA murine model of DBA, RPS19 insufficient erythroid cells may proliferate poorly because of p53-mediated cell cycle arrest, and also because of decreased expression of the key erythroid signalling protein KIT.

    Full Text Available Introduction. Coeliac disease (CD is a permanent intolerance of gluten, i.e. of gliadin and related proteins found in the endosperm of wheat, rye and barley. It is characterized by polygenic predisposition, autoimmune nature, predominantly asymptomatic or atypical clinical course, as well as by high prevalence in patients with Down's syndrome (DS and some other diseases. Outline of Cases. We are presenting a girl and two boys, aged 6-7 (X=6.33 years with DS and CD recognized under the feature of sideropenic anaemia resistant to oral therapy with iron. Beside mental retardation, low stature and the morphological features characteristic of DS, two patients had a congenital heart disease; one ventricular septal defect and the other atrioventricular canal. In two patients, trisomy on the 21st chromosome pair (trisomy 21 was disclosed in all cells, while one had a mosaic karyotype. All three patients had classical laboratory parameters of sideropenic anaemia: blood Hb 77-89 g/l (X=81.67, HCT 0.26-0.29% (X=0.28, MCV 69-80 fl (X=73, MCH 24.3-30 pg (X=26.77 and serum iron 2-5 μmol/L (X=4.0. Beside anaemia and in one patient a mild isolated hypertransaminasemia (AST 67 U/l, ALT 62 U/l, other indicators of CD were not registered in any of the children. In addition, in all three patients, we also detected an increased level of antibodies to tissue transglutaminase (atTG of IgA class (45-88 U/l so that we performed endoscopic enterobiopsy in order to reliably confirm the diagnosis of CD. In all three patients, the pathohistological finding of the duodenal mucosa specimen showed mild to moderate destructive enteropathy associated with high intraepithelial lymphocyte infiltration, cryptic hyperplasia and lympho-plasmocytic infiltration of the stroma. In all three patients, the treatment with a strict gluten-free diet and iron therapy applied orally for 3-4 months resulted in blood count normalization and the correction of sideropenia.

    On the Belgica expedition (1897-1899), Dr F.A. Cook described a disease that he called 'polar anaemia' and on this expedition it affected most of the expedition members and caused one death. The symptoms were shortness of breath, abnormalities of the pulse and oedema (swelling of the legs) and the disease was clearly cardiac failure. During the heroic age of Antarctic exploration a similar disease affected at least eight other expeditions causing five other deaths. This disease was very similar (and probably identical) to a disease affecting (mostly) Scandinavian seamen and called 'ship beri-beri'. Both diseases were almost certainly what is now called wet beri-beri due to thiamine (vitamin B1) deficiency though most sufferers were probably also vitamin C deficient and some may have had both beri-beri and scurvy. It may have been exacerbated by invalid diets. This paper describes the disease and how it was considered and treated at the time.

    Vitamin D deficiency is highly prevalent in the US population and is associated with numerous diseases, including those characterised by inflammatory processes. We aimed to investigate the link between vitamin D status and anaemia, hypothesising that lower vitamin D status would be associated with increased odds of anaemia, particularly anaemia with inflammation. A secondary aim was to examine the effects of race in the association between vitamin D status and anaemia. We conducted a cross-sectional analysis in a cohort of generally healthy adults in Atlanta, GA (n 638). Logistic regression was used to evaluate the association between vitamin D status and anaemia. Serum 25-hydroxyvitamin D (25(OH)D) anaemia in bivariate analysis (OR 2·64, 95% CI 1·43, 4·86). There was significant effect modification by race (P= 0·003), such that blacks with 25(OH)D anaemia (OR 6·42, 95% CI 1·88, 21·99), v. blacks with 25(OH)D ≥ 50 nmol/l, controlling for potential confounders; this association was not apparent in whites. When categorised by subtype of anaemia, blacks with 25(OH)D anaemia with inflammation than blacks with serum 25(OH)D ≥ 50 nmol/l (OR 8·42, 95% CI 1·96, 36·23); there was no association with anaemia without inflammation. In conclusion, serum 25(OH)D anaemia, particularly anaemia with inflammation, among blacks in a generally healthy adult US cohort.

    Megaloblastic anaemia 1 (MGA1) is a rare autosomal recessive condition characterized by selective intestinal vitamin B12 malabsorption and proteinuria. More than 200 MGA1 patients have been identified worldwide, but the disease is relatively prevalent in Finland, Norway and several Eastern Mediterranean regions. MGA1 is genetically heterogeneous and can be caused by mutations in either the cubilin (CUBN) or the amnionless (AMN) gene. In the present study we investigated the molecular defect underlying MGA1 in nine Tunisian patients belonging to six unrelated consanguineous families. Haplotype and linkage analyses, using microsatellite markers surrounding both CUBN and AMN genes, indicated that four out of the six families were likely to be linked to the CUBN gene. Patients from these families were screened for the Finnish, Mediterranean and Arabian mutations already published. None of the screened mutations could be detected in our population. One family showed a linkage to AMN gene. Direct screening of the AMN gene allowed the identification of the c.208-2A>G mutation, previously described in a Jewish Israeli patient of Tunisian origin and in Turkish patients. This suggests that the c.208-2A>G mutation may derive from a single Mediterranean founder ancestor. For the last family, haplotype analysis excluded both CUBN and AMN genes, suggesting the existence of a third locus that may cause MGA1.

    Fasciola infection (fascioliasis) appeared to be endemic in Egypt. Stool samples of fourty eight patients were coprologically diagnosed. According to Fasciola egg counting per gram stool, the severity of infection was divided into light infection in 60.5%, moderate in 27.1% and severe infection in 12.5%. No significant correlation was detected between severity of infection and patients' sex. Complete blood picture, reticylocytic count, serum iron, immunological assays as anti-nuclear, anti-smooth muscle antibody, anti-mitochondrial anti-body, anti-DNA tests and rheumatoid factor and occult blood in stool were investigated. Normocytic normochromic anaemia was detected in 62.5% of the fascioliasis patients, microcytic hypochromic anaemia in 31.3% and macrocytic one in 6.3%. Highly significant negative correlation (R = -0.68) was detected between haemoglobin concentration and egg count per gram faeces. Human fascioliasis was associated with normocytic normochromic anaemia and to a lesser extent microcytic hypochromic anemia.

    Full Text Available Abstract Introduction Iron deficiency is the most common cause of anaemia worldwide. Pica, the ingestion of substances that are inappropriate for consumption, is associated with iron deficiency and may be under-diagnosed. Case presentation A 34-year-old woman presented with iron deficiency anaemia refractory to treatment for more than a decade. The clinical presentation, endoscopic findings and laboratory investigations were consistent with pica. Subsequent geophysical analysis confirmed that the ingested material was kaolin, a negatively charged silicate. Conclusion Prolonged unexplained iron deficiency anaemia should prompt clinicians to remember and inquire about pica. In our patient, this would have averted numerous unnecessary investigations and prevented a decade-long suffering.

    anaemia in the population of children admitted to KDH were precipitated by B19. While this is a relatively small proportion, this has to be evaluated in the light of the IgG data that shows that less than 15% of children in the study were exposed to B19, a figure much lower than reported in other tropical areas.

    Full Text Available BACKGROUND: Severe anaemia is a major cause of morbidity and mortality in African children. The aetiology is multi-factorial, but interventions have often targeted only one or a few causal factors, with limited success. METHODS AND FINDINGS: We assessed the contribution of different pathophysiological mechanisms (red cell production failure [RCPF], haemolysis and blood loss to severe anaemia in Malawian children in whom etiological factors have been described previously. More complex associations between etiological factors and the mechanisms were explored using structural equation modelling. In 235 children with severe anaemia (haemoglobin<3.2 mMol/L [5.0 g/dl] studied, RCPF, haemolysis and blood loss were found in 48.1%, 21.7% and 6.9%, respectively. The RCPF figure increased to 86% when a less stringent definition of RCPF was applied. RCPF was the most common mechanism in each of the major etiological subgroups (39.7-59.7%. Multiple aetiologies were common in children with severe anaemia. In the final model, nutritional and infectious factors, including malaria, were directly or indirectly associated with RCPF, but not with haemolysis. CONCLUSION: RCPF was the most common pathway leading to severe anaemia, from a variety of etiological factors, often found in combination. Unlike haemolysis or blood loss, RCPF is a defect that is likely to persist to a significant degree unless all of its contributing aetiologies are corrected. This provides a further explanation for the limited success of the single factor interventions that have commonly been applied to the prevention or treatment of severe anaemia. Our findings underline the need for a package of measures directed against all of the local aetiologies of this often fatal paediatric syndrome.

    Full Text Available Use of current models of Automated Haematology Analysers help in calculating the haemoglobin contents of the mature Red cells, Reticulocytes and percentages of Microcytic and hypochromic Red cells. This has helped the clinician in reaching early diagnosis and management of Different haemopoietic disorders like Iron Deficiency Anaemia, Thalassaemia and anaemia of chronic diseases. AIM This study is conducted using an Automated Haematology Analyser to evaluate anaemia using the Red Cell and Reticulocyte parameters. Three types of anaemia were evaluated; iron deficiency anaemia, anaemia of long duration and anaemia associated with chronic disease and Iron deficiency. MATERIALS AND METHODS The blood samples were collected from 287 adult patients with anaemia differentiated depending upon their iron status, haemoglobinopathies and inflammatory activity. Iron deficiency anaemia (n=132, anaemia of long duration (ACD, (n=97 and anaemia associated with chronic disease with iron deficiency (ACD Combi, (n=58. Microcytic Red cells, hypochromic red cells percentage and levels of haemoglobin in reticulocytes and matured RBCs were calculated. The accuracy of the parameters was analysed using receiver operating characteristic analyser to differentiate between the types of anaemia. OBSERVATIONS AND RESULTS There was no difference in parameters between the iron deficiency group or anaemia associated with chronic disease and iron deficiency. The hypochromic red cells percentage was the best parameter in differentiating anaemia of chronic disease with or without absolute iron deficiency with a sensitivity of 72.7% and a specificity of 70.4%. CONCLUSIONS The parameters of red cells and reticulocytes were of reasonably good indicators in differentiating the absolute iron deficiency anaemia with chronic disease.

    Full Text Available CASE REPORT A 63-year old man with refractory anaemia with excess of blasts and a history of heart failure, diabetes and hyperuricaemia, presented with pain, warmth and swelling in the left knee. Blood sample showed white cell blood count 3,840/μL (normal formula, haemoglobin 7.1 g/dL, platelets 117,000/L, eritrosedimentation rate 66 mm/h, normal serum creatinine and uric acid. He had no history of neutropenia, fever or recurrent infections. X-ray of the knee did not show any erosion or lytic lesion. Arthrocentesis produced turbid fluid, with elevated cell count (81,000/μL, mainly polimorphonuclear cells, no urate crystals, normal chemical pattern, sterile culture. Synovial fluid smear showed a huge neutrophilic cellularity with scattered mononuclear cells looking like medullar myeloid blasts. The microscopic examination identified a myeloid infiltration as the cause of arthritis. DISCUSSION AND CONCLUSIONS Rheumatic phenomena in myelodysplastic syndromes have a prevalence of 10% and include vasculitis, neuropaties, glomerulonephritis, lupus-like syndrome, inflammatory bowel disease, lung infiltrates and arthritis. The pathogenesis is usually autoimmune, as in all paraneoplastic syndromes. In our case, arthritis was due to a direct invasion of blasts. This phenomenon is rarely observed in acute leukemias and was not described yet in myelodysplastic syndromes. Synovial fluid analysis is critical to define the ethiology of an articular effusion, microscopical examination is strongly recommended but it is not always carried out. This case shows how simple diagnostic tests can easily disclose rare conditions.

    Anaemia in patients with diabetes, both type 1 and type 2, is a frequent clinical finding. The mechanisms of anaemia are multifactorial and often not very well understood. Iatrogenic causes, including oral antidiabetic drugs, ACE inhibitors and ARBs, and renal insufficiency are the major causes of anaemia in patients with type 2 diabetes. In patients with type 1, the cause is often an associated autoimmune disease, and screening for autoimmune gastritis, pernicious anaemia, Hashimoto's thyroiditis, coeliac disease and Addison's disease is recommended. Other rare causes - including G6PD deficiency, microangiopathic haemolytic anaemia and thiamine-responsive megaloblastic anaemia - should be suspected in young patients or when the classical causes are excluded. Early detection and recognition of the cause(s) of anaemia in patients with diabetes could help to prevent other clinical manifestations as well as the complications of diabetes.

This study was aimed to assess the prevalence of anaemia and kidney dysfunction in Caribbean type 2 diabetic patients that have been previously shown to have a high prevalence of the metabolic syndrome. Methods 155 type 2 diabetic patients and 51 non-diabetic subjects of African origin were studied. Anthropometric parameters were measured and fasting blood samples were collected for glucose, creatinine, glycated hemoglobin and complete blood count. Anaemia was defined as haemoglobin 2. Comparisons for within- and between-gender, between diabetic and non-diabetic subjects were performed using Student's t-test while chi-square test was employed for categorical variables. Results The diabetic patients were older than the non-diabetic subjects. While male non-diabetic subjects had significantly higher red blood cell count (RBC, haemoglobin and hematocrit concentrations than non-diabetic female subjects (p 2, p Conclusion A high prevalence of anaemia was identified in this group of type 2 diabetic patients previously shown to have a high prevalence of the metabolic syndrome. It is therefore recommended that diagnostic laboratories in developing countries and elsewhere should include complete blood count in routine laboratory investigations in the management of diabetic patients.

  17. Malaria-related anaemia: a Latin American perspective

    Full Text Available Malaria is the most important parasitic disease worldwide, responsible for an estimated 225 million clinical cases each year. It mainly affects children, pregnant women and non-immune adults who frequently die victims of cerebral manifestations and anaemia. Although the contribution of the American continent to the global malaria burden is only around 1.2 million clinical cases annually, there are 170 million inhabitants living at risk of malaria transmission in this region. On the African continent, where Plasmodium falciparum is the most prevalent human malaria parasite, anaemia is responsible for about half of the malaria-related deaths. Conversely, in Latin America (LA, malaria-related anaemia appears to be uncommon, though there is a limited knowledge about its real prevalence. This may be partially explained by several factors, including that the overall malaria burden in LA is significantly lower than that of Africa, that Plasmodium vivax, the predominant Plasmodium species in the region, appears to display a different clinical spectrus and most likely because better health services in LA prevent the development of severe malaria cases. With the aim of contributing to the understanding of the real importance of malaria-related anaemia in LA, we discuss here a revision of the available literature on the subject and the usefulness of experimental animal models, including New World monkeys, particularly for the study of the mechanisms involved in the pathogenesis of malaria.

    A nutritional anaemia survey was carried out on 610 11-year-old coloured, black and white schoolchildren in urban and rural communities in the western Cape. The mean (+/- 1 SD) haemoglobin concentration was 13.0 +/- 1.2 g/dl. The coloured and black subgroups considered together had a significantly lower mean haemoglobin concentration than the white subgroup (12.8 +/- 1.2 g/dl v. 13.4 +/- 1.0 g/dl) (F = 37.47; P less than 0.0001). The urban population as a whole had a significantly lower geometric mean (1 SD range) serum ferritin concentration than the rural population (25.6 (13.5-48.6) micrograms/l v. 34.1 (21.3-54.6) micrograms/l) (F = 42.94; P less than 0.0001). The lowest geometric mean serum ferritin values were found in the urban coloured (23.1 (11.5-46.4) micrograms/l) and urban black schoolchildren (23.7 (13.2-42.6) micrograms/l), with figures of less than 12 micrograms/l in 11.7% and 12.5% respectively. Although 28% of the children had red cell folate values below the recommended lower limit of normal (175 ng/ml), probability plot analysis of the data suggested that folate deficiency was not a major problem in the study population. The calculated daily iron and folate intakes were below the age-related recommended dietary allowance (RDA) in all the subgroups, yet anaemia was relatively uncommon. These findings suggest that the RDA values are too high. Overall the prevalence of nutritional anaemia was low and only the urban coloured subgroup showed significant second populations with low haemoglobin and serum ferritin measurements.

    There is a high prevalence of anaemia among patients admitted to the intensive care unit (ICU), and it may have a negative effect on patient's outcome. The most common treatment for anaemia in the ICU patient is allogeneic blood transfusion (ABT), yet it has been found to be a risk factor associated with an increased risk of morbidity and mortality in critical care patients. As a reduction of erythropoietin secretion and action is observed in most ICU patients, the administration of (rHuEPO) has emerged as a therapeutic option. Unfortunately, the results from different studies show that rHuEPO treatment results in a small reduction of ABT requirements when "restrictive" transfusion criteria are applied, which has only been supported by three of the studies. Yet this did not result in a decreased mortality rate, except for patients with a diagnosis on admission of trauma in two studies, even though one study reported a dose-dependent increase of thrombotic vascular events among patients without thromboprophylaxis. Altogether, clinical data suggest a role for rHuEPO in the treatment of anaemia in trauma patients, especially in those sustaining neurotrauma, whereas for non-trauma patients without an approved indication, rHuEPO administration is an expensive approach, does not seem to improve outcome, and might result in serious adverse effects. Consequently, more basic and clinical studies are required to ascertain which patients are more likely to benefit from these treatments, as well as to identify the optimal doses and administration schedules, and iron administration.

    Full Text Available INTRODUCTION Anaemia is a serious and prominent problem in the developing countries. This study evaluates the prevalence of anaemia in pregnant women attending the outpatient clinic in a semi-urban hospital for a period of six months. MATERIALS AND METHODS Data from a sample of 500 pregnant women was collected and the patients were screened for anaemia on their booking visit in KFMS&R for a period of six months from March-August 2015. Haemoglobin was estimated by cyanmethaemoglobin method using Systronic photocolorimeter on their first antenatal visit. The degree of anaemia was categorised according to ICMR datamild (10-10.99 g/dL, moderate (7-9.99 g/dL, severe (<7 g/dL. RESULTS It was observed that the prevalence of anaemia was 51.8% in the population under study. The prevalence of mild anaemia was 18.53%, that of moderate anaemia was 63.70% and that of severe anaemia was 17.76%. It was also noticed that the prevalence of anaemia was higher in young pregnant women between 17-21 years of age (63.26%. CONCLUSION Anaemia continues to be a major health problem in India and prevention and early diagnosis will significantly reduce maternal and perinatal morbidity and mortality.

    Full Text Available Endurance athletes require a very efficient oxygen transport system for maximal aerobic power during physical work performance. Many studies carried on endurance athletes suggested low levels of red blood cell markers leading to misconception of existence of so called sports anaemia in athletes. Sometimes athletes are on needless iron supplementation and are concern about anaemia. The main objectives of the study were to investigate the red cell population markers and to study the sports anaemia phenomenon in endurance athletes and the underlying responses responsible for ot. 60 male endurance track and field runners age group 18-21 were selected from the local city based club named Vasant Desai Krida Sangh Akola and were compared with the age, height sex matched non athletes students of Govt. Medical College Akola. The seven red blood cell markers were studied from the blood samples taken from the cubital vein under standard conditions. The blood variables for both the groups were analyzed with an automatic cell counter. The mean values of Hb(12.27 gm% +/- 0.782, RBC count in(3.64millions per cu mm+/-0.52, hematocrit ( 41.58 % +/- 1.32, mean corpuscular Hb conc (MCHC 29.49% +/- 1.198 were all very significantly lower ( p<0.0001 as compare to controls. Whereas the plasma volume (58.412% +/- 1.32, Mean Corpuscular volume (MCV 115.06 cu microns+/- 11.54, Mean Hb conc (MCH 33.998 picogms+/- 2.608, were significantly increased in endurance athletes. Though decrease in Hb conc, Low RBC count and less hematocrit in endurance athletes indicate presence of anaemia in them but it’s not a true anaemia as it is also confirmed by MCV, MCH, MCHC values between the two groups. The significant differences between the groups are due to the response to endurance training leading to hemo dilutional anaemia caused by plasma volume expansion which increases the blood volume in endurance athletes helping them for better oxygen supply and aerobic power needed

    Full Text Available Iron deficiency anaemia (IDA is the most common nutritional deficiency in the world including developed and developing countries. Despite intensive efforts to improve the quality of life of rural and aboriginal communities in Malaysia, anaemia and IDA are still major public health problems in these communities particularly among children. A randomized, double-blind, placebo-controlled trial was conducted on 250 Orang Asli (aboriginal schoolchildren in Malaysia to investigate the effects of a single high-dose of vitamin A supplementation (200,000 IU on iron status indices, anaemia and IDA status. The effect of the supplement was assessed after 3 months of receiving the supplements; after a complete 3-day deworming course of 400 mg/day of albendazole tablets. The prevalence of anaemia was found to be high: 48.5% (95% CI = 42.3, 54.8. Moreover, 34% (95% CI = 28.3, 40.2 of the children had IDA, which accounted for 70.1% of the anaemic cases. The findings showed that the reduction in serum ferritin level and the increments in haemoglobin, serum iron and transferrin saturation were found to be significant among children allocated to the vitamin A group compared to those allocated to the placebo group (p < 0.01. Moreover, a significant reduction in the prevalence of IDA by almost 22% than prevalence at baseline was reported among children in the vitamin A group compared with only 2.3% reduction among children in the placebo group. In conclusion, vitamin A supplementation showed a significant impact on iron status indices and IDA among Orang Asli children. Hence, providing vitamin A supplementation and imparting the knowledge related to nutritious food should be considered in the efforts to improve the nutritional and health status of these children as a part of efforts to improve the quality of life in rural and aboriginal communities.

    Background: Many patients with solid tumours or nonmyeloid haematopoietic tumours develop symptomatic anaemia, which has a major impact on quality of life (QoL). The efficacy of erythropoiesis-stimulating agents (ESAs) in improving QoL and reducing blood transfusions has been widely demonstrated. Binocrit® (biosimilar epoetin alfa) is an ESA indicated in the European Union for treating chemotherapy-induced anaemia. The aim of this study was to investigate the effect of Binocrit® on haemoglobin (Hb) levels in anaemic cancer patients in Italian clinical practice. Methods: The ANEMONE study was a national, longitudinal, retrospective, multicentre observational study. Patients had to be 18 years or older, with a solid tumour or non-Hodgkin’s lymphoma, Hodgkin’s disease or multiple myeloma, receiving chemotherapy, and treated with Binocrit® to manage chemotherapy-induced anaemia. The primary outcomes were the proportion of patients with a Hb increase ⩾1 g/dl during the first 4 weeks and with a Hb increase ⩾2 g/dl during the first 12 weeks. Results: A total of 245 patients were enrolled and 215 patients were evaluable for statistical analysis. In the first 4 weeks, 49.3% of patients showed an increase in Hb of ⩾1 g/dl: 45.5% in patients with solid tumours and 52.1% in patients with haematological malignancies. In the first 12 weeks, 51.6% of patients showed an increase in Hb of ⩾2 g/dl (48.4% solid tumours, 54.2% haematological diseases). Treatment with Binocrit® was well tolerated. Conclusions: These results confirm the effectiveness and safety of Binocrit® for chemotherapy-induced anaemia in routine practice in patients with solid tumours, lymphoma and myeloma. PMID:28203295

    Iron deficiency anaemia (IDA) is the most common nutritional deficiency in the world including developed and developing countries. Despite intensive efforts to improve the quality of life of rural and aboriginal communities in Malaysia, anaemia and IDA are still major public health problems in these communities particularly among children. A randomized, double-blind, placebo-controlled trial was conducted on 250 Orang Asli (aboriginal) schoolchildren in Malaysia to investigate the effects of a single high-dose of vitamin A supplementation (200,000 IU) on iron status indices, anaemia and IDA status. The effect of the supplement was assessed after 3 months of receiving the supplements; after a complete 3-day deworming course of 400 mg/day of albendazole tablets. The prevalence of anaemia was found to be high: 48.5% (95% CI=42.3, 54.8). Moreover, 34% (95% CI=28.3, 40.2) of the children had IDA, which accounted for 70.1% of the anaemic cases. The findings showed that the reduction in serum ferritin level and the increments in haemoglobin, serum iron and transferrin saturation were found to be significant among children allocated to the vitamin A group compared to those allocated to the placebo group (pchildren in the vitamin A group compared with only 2.3% reduction among children in the placebo group. In conclusion, vitamin A supplementation showed a significant impact on iron status indices and IDA among Orang Asli children. Hence, providing vitamin A supplementation and imparting the knowledge related to nutritious food should be considered in the efforts to improve the nutritional and health status of these children as a part of efforts to improve the quality of life in rural and aboriginal communities.

    The generation of induced pluripotent stem (iPS) cells has enabled the derivation of patient-specific pluripotent cells and provided valuable experimental platforms to model human disease. Patient-specific iPS cells are also thought to hold great therapeutic potential, although direct evidence for this is still lacking. Here we show that, on correction of the genetic defect, somatic cells from Fanconi anaemia patients can be reprogrammed to pluripotency to generate patient-specific iPS cells. These cell lines appear indistinguishable from human embryonic stem cells and iPS cells from healthy individuals. Most importantly, we show that corrected Fanconi-anaemia-specific iPS cells can give rise to haematopoietic progenitors of the myeloid and erythroid lineages that are phenotypically normal, that is, disease-free. These data offer proof-of-concept that iPS cell technology can be used for the generation of disease-corrected, patient-specific cells with potential value for cell therapy applications.

    Objectives It is widely assumed that, at matched transfusional iron-loading rates, responses to chelation therapy are similar, irrespective of the underlying condition. However, data are limited for rare transfusion-dependent anaemias, and it remains to be elucidated if response differs, depending on whether the anaemia has a primary haemolytic or production mechanism. Methods The efficacy and safety of deferasirox (Exjade®) in rare transfusion-dependent anaemias were evaluated over 1 yr, with change in serum ferritin as the primary efficacy endpoint. Initial deferasirox doses were 10–30 mg/kg/d, depending on transfusion requirements; 34 patients had production anaemias, and 23 had haemolytic anaemias. Results Patients with production anaemias or haemolytic anaemias had comparable transfusional iron-loading rates (0.31 vs. 0.30 mL red blood cells/kg/d), mean deferasirox dosing (19.3 vs. 19.0 mg/kg/d) and baseline median serum ferritin (2926 vs. 2682 ng/mL). Baseline labile plasma iron (LPI) levels correlated significantly with the transfusional iron-loading rates and with serum ferritin levels in both cohorts. Reductions in median serum ferritin levels were initially faster in the production than the haemolytic anaemias, but at 1 yr, similar significant reductions of 940 and 617 ng/mL were attained, respectively (−26.0% overall). Mean LPI decreased significantly in patients with production (P < 0.0001) and haemolytic (P = 0.037) anaemias after the first dose and was maintained at normal mean levels (<0.4 μm) subsequently. The most common drug-related, investigator-assessed adverse events were diarrhoea (n = 16) and nausea (n = 12). Conclusions At matched transfusional iron-loading rates, the responses of rare transfusion-dependent anaemias to deferasirox are similar at 1 yr, irrespective of the underlying pathogenic mechanism.

    This systematic review synthesizes the relevant published articles on the prevalence of anaemia in patients with chronic obstructive pulmonary disease (COPD) and its relationship with inflammatory markers. The upregulation of erythropoietin in anaemia maintains homeostasis. However, anaemic COPD patients do not respond to increased levels of erythropoietin. The increased levels could be an indicator of the peripheral erythropoietin resistance in COPD. Anaemia and inflammation are associated with an increased risk of hospitalization and mortality in these patients. The understanding of anaemia in chronic inflammation is that anaemia is at least partially due to the excessive production of inflammatory cytokines, which can contribute to improvements in the management, prognosis, and survival of patients with COPD and anaemia.

    BACKGROUND: Severe anaemia is a major complication of malaria but little is known about its pathogenesis. Experimental models have implicated tumour necrosis factor (TNF) in induction of bone-marrow suppression and eythrophagocytosis. Conversely, interleukin 10 (IL-10), which mediates feed......-back regulation of TNF, stimulates bone-marrow function in vitro and counteracts anaemia in mice. We investigated the associations of these cytokines with malarial anaemia. METHODS: We enrolled 175 African children with malaria into two studies in 1995 and 1996. In the first study, children were classified...... as having severe anaemia (n=10), uncomplicated malaria (n=26), or cerebral anaemia (n=41). In the second study, patients were classified as having cerebral malaria (n=33) or being fully conscious (n=65), and the two groups were subdivided by measured haemoglobin as normal (>110 g/L), moderate anaemia (60...

    Aplastic anaemia is a rare and serious disease characterised by severe immunosuppression due to prolonged neutropenia and the use of immunosuppressants such as corticosteroids, cyclosporine and antithymocyte globulin. Candida species are pathogens of low virulence colonising the skin and the digestive tract of many healthy individuals. Nonetheless, the incidence of invasive candidal infection is increasing. The widespread use of central intravascular catheters, invasive procedures, broad-spectrum antibiotics and immunosuppresion predisposes patients to these infections. Eye, skin, cardiac, liver, spleen and brain infection are the most common sites of invasive candidiasis. Bone and joint infections are less frequent and Candida hip septic arthritis is extremely rare. We present here a patient treated for aplastic anaemia, who developed fungal arthritis of the hip and systemic candidaemia.

    Fanconi's anaemia is a severe refractory anaemia, associated with congenital malformations in approximately two-thirds of cases. Although these malformations may involve every organ system, suggestive dysmorphic features include growth retardation, radial ray deformities and urinary malformations. These malformations are not specific for Fanconi's anaemia, but should be recognized during pregnancy, or later in childhood, and suggest the possibility of inherited haematopoiesis disorders.

    Full Text Available Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality.The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of 'low risk' women participating in a large international multicentre prospective study (n = 5 609, to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation.The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization's definition of anaemia in pregnancy (haemoglobin < 11g/dL. Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work was the main method of analysis.The hallmark findings were the low prevalence of anaemia (2.2%, that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78, and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score < 7 at one and five minutes. Adverse pregnancy outcomes were however more common in those with anaemia than in those without.In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia's conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy.

    Background & objectives: Iron deficiency anaemia (IDA) is the most common nutritional deficiency in pregnancy. Prophylactic oral iron is recommended during pregnancy to meet the increased requirement. In India, women become pregnant with low baseline haemoglobin level resulting in high incidence of moderate to severe anaemia in pregnancy where oral iron therapy cannot meet the requirement. Pregnant women with moderate anaemia are to be treated with parentral iron therapy. This study was under...

    Iron is an essential micronutrient in many cellular processes. Iron deficiency, with or without anaemia, is common in patients with chronic heart failure. Observational studies have shown iron deficiency to be associated with worse clinical outcomes and mortality. The treatment of iron deficiency in chronic heart failure patients using intravenous iron alone has shown promise in several clinical trials, although further studies which include larger populations and longer follow-up times are needed.

    Iron deficiency anaemia is frequently seen in the paediatric age group. Modifying the treatment options according to the affected area resources will help accessibility and compliance to treatment. Response of children with Iron deficiency anaemia to a natural hematinic (Carboadeim) versus iron syrup plus folic acid treatment was compared in this study. This is a prospective, interventional, controlled, hospital-based study conducted among children with iron deficiency anaemia residing in Hussein Village, Gezira State who attended Giad Hospital. Patients were randomly divided into two groups; the control received iron supplements and folic acid, and the case received a combination of carrots, baobab (Adansonia digitata) and godeim (Grewia tenax) which is known as (Carboadeim). Blood tests were taken for investigations at start of treatment, after 7-10 days, 6 weeks and 3 months. Complete blood count, reticulocyte count and serum ferritin were taken as indicators. The mean haemoglobin level initially in the cases and controls was 7.38 and 7.35 gm/dL, respectively; after three months the mean was 11.67 and 11.384 gm/dL, respectively. The mean serum ferritin in the case and control groups was found to be 10.30 and 10.87 ng/ml, respectively at the start of treatment; and after 3 months they were reported to be 44.34 and 75.7 ng/ml confirming the positive response to treatment by Carboadeim. In conclusion Carboadeim is a naturally available and cost-effective hematinic blend that might be added to the food menu as a supplement as well as a treatment of nutritional anaemia in children.

    Infections remain an issue of particular relevance in renal transplant patients, particularly viral infections. Human parvovirus B19 infection causes severe refractory anaemia, pancytopenia and thrombotic microangiopathy. Its presence is recognized by analysing blood polymerase chain reaction (PCR) and by the discovery of typical giant proerythroblasts in the bone marrow. We report the case of a 65 year-old man with a history of deceased donor renal transplant in September 2014. At 38 days after the transplant, the patient presented progressive anaemia that was resistant to erythropoiesis-stimulating agents. At 64 days after transplant, hyperthermia occurred with progressive deterioration of the patient's general condition. The viral serology and the first blood PCR for human parvovirus B19 were both negative. At 4 months and 19 days after, a bone marrow biopsy was conducted, showing giant erythroblasts with nuclear viral inclusions that were compatible with parvovirus; a PCR in the tissue confirmed the diagnosis. A second blood PCR was positive for parvovirus. After treatment with intravenous immunoglobulin and the temporary discontinuation of mycophenolate mofetil, a complete remission of the disease occurred, although the blood PCR for parvovirus B19 remained positive, so monitoring is necessary for future likely recurrence.

    Full Text Available Kawasaki disease (KD is one of the most common vasculitis disorders of childhood, affecting predominantly medium-sized arteries, particularly the coronary arteries. For treatment, high-dose intravenous immunoglobulin (IVIG is indicated. IVIG infusions are usually safe and well tolerated even though serious complications can be observed. We present a brief overview of KD and report a two-year-old girl with KD and two IVIG infusions (Gammagard® because of persistent fever after the completion of the first IVIG. Haemolytic anaemia developed after IVIG retreatment. The direct antiglobulin test after haemolysis was positive. The etiology of the haemolysis was related to the presence of transient, passively acquired antibodies that cause a direct antibody-mediated attack. There are few reports of haemolytic anaemia after IVIG infusions. The haemolysis in KD is dose-dependent and occurs more frequently after the second IVIG dose. Non-0 blood group patients are at greater risk. Another factor increasing the risk of haemolysis is also the presence of anaemia due to inflammation in KD.

  19. Abnormalities of gonadal differentiation.

    1998-04-01

    Gonadal differentiation involves a complex interplay of developmental pathways. The sex determining region Y (SRY) gene plays a key role in testis determination, but its interaction with other genes is less well understood. Abnormalities of gonadal differentiation result in a range of clinical problems. 46,XY complete gonadal dysgenesis is defined by an absence of testis determination. Subjects have female external genitalia and come to clinical attention because of delayed puberty. Individuals with 46,XY partial gonadal dysgenesis usually present in the newborn period for the valuation of ambiguous genitalia. Gonadal histology always shows an abnormality of seminiferous tubule formation. A diagnosis of 46,XY true hermaphroditism is made if the gonads contain well-formed testicular and ovarian elements. Despite the pivotal role of the SRY gene in testis development, mutations of SRY are unusual in subjects with a 46,XY karyotype and abnormal gonadal development. 46,XX maleness is defined by testis determination in an individual with a 46,XX karyotype. Most affected individuals have a phenotype similar to that of Klinefelter syndrome. In contrast, subjects with 46,XX true hermaphroditism usually present with ambiguous genitalia. The majority of subjects with 46,XX maleness have Y sequences including SRY in genomic DNA. However, only rare subjects with 46,XX true hermaphroditism have translocated sequences encoding SRY. Mosaicism and chimaerism involving the Y chromosome can also be associated with abnormal gonadal development. However, the vast majority of subjects with 45,X/46,XY mosaicism have normal testes and normal male external genitalia.

    Although its exact mechanism is unclear, anaemia is well recognised as a feature of hypopituitarism; and anaemia is associated with Sheehan's syndrome (SS). We aimed to evaluate the frequency and severity of anaemia and other haematological changes among patients with Sheehan's syndrome, in comparison with healthy controls. Sixty-five SS patients and 55 age-matched female healthy controls were included. Biochemical and hormonal assessments and haematological evaluations were carried out, and groups were compared. The mean number of red blood cells, as well as mean haemoglobin, iron and erythropoietin levels, total iron-binding capacity and transferrin saturation were all significantly lower in SS patients compared to controls. SS patients had significantly higher rates of anaemia (80.0% vs. 25.5%, p = 0.0001), iron deficiency (44.6% vs. 5.4%, p = 0.001), leukopenia (20.0% vs. 5.4%, p = 0.015), thrombocytopenia (9.2% vs. 0.0%, p = 0.028) and bicytopenia (21.5% vs. 1.8%, p = 0.001) compared to controls. Anaemic SS patients had normochromic-normocytic anaemia (55%) or hypochromic-microcytic anaemia (45%). Anaemia is frequently associated with Sheehan's syndrome and responds to appropriate replacement therapy. Hypopituitarism should be considered as a possible cause of anaemia, and a hormone examination should be undertaken promptly, particularly in patients with anaemia resistant to therapy and/or with a history suggestive of Sheehan's syndrome.

    Few data exist on the aetiology of anaemia and Fe deficiency (ID) during early infancy in South Asia. The present study aimed to determine the contribution of ID, infections and feeding practices to anaemia in Bangladeshi infants aged 6-11 months. Baseline data from 1600 infants recruited into a cluster-randomised trial testing the effectiveness of micronutrient powder sales by frontline health workers on the prevalence of anaemia were used. Multivariate logistic regression was used to identify risk factors for anaemia and ID, and population attributable fractions (PAF) were computed to estimate the proportion of anaemia that might be prevented by the elimination of individual risk factors. It was found that 68 % of the infants were anaemic, 56 % were Fe deficient, and one-third had evidence of subclinical infections. The prevalence of anaemia and ID increased rapidly, until 8-9 months of age, while that of subclinical infections was constant. ID (adjusted OR (AOR) 2·6-5·0; Panaemia, in addition to age and male sex. Similarly, subclinical infections, age and male sex were significant risk factors for ID. Previous-day consumption of Fe-rich foods was very low and not associated with anaemia or ID. The PAF of anaemia attributable to ID was 67 % (95 % CI 62, 71) and that of subclinical infections was 16 % (95 % CI 11, 20). These results suggest that a multipronged strategy that combines improvements in dietary Fe intake alongside infection control strategies is needed to prevent anaemia during infancy in Bangladesh.

  3. Prevalence and Severity of Anaemia Stratified by Age and Gender in Rural India

    Full Text Available Anaemia is a major public health problem in India. Although nearly three quarters of the Indian population live in rural areas, the epidemiology of anaemia in rural settings is not well known. We performed a retrospective observational study using routine clinical data from patients attending the out-patient clinics of a rural hospital in India from June 2011 to August 2014. The study included 73,795 determinations of haemoglobin. 49.5% of patients were female. The median haemoglobin concentration was 11.3 g/dL (interquartile range (IQR, 9.8–12.4 in females and 12.5 g/dL (IQR, 10.6–14.2 in males. Anaemia was present in the majority of children <10 years, women after puberty, and older adults. Children <5 years had the highest prevalence of anaemia, especially children aged 1-2 years. The high proportion of microcytic anaemia and the fact that gender differences were only seen after the menarche period in women suggest that iron deficiency was the main cause of anaemia. However, the prevalence of normocytic anaemia increased with age. The results of this study can be used by public health programmes to design target interventions aimed at reducing the huge burden of anaemia in India. Further studies are needed to clarify the aetiology of anaemia among older adults.

    The present study was carried out to find out the prevalence and etiology of nutritional anaemia among preschool children from an urban slum. Randomly selected 300 children aged 3 months-3 yr were analysed over a period of one year for estimating prevalence of nutritional anaemia. Prevalence was also assessed by the rise in haemoglobin after 8 wk of haematinic supplementation in 159 of the 300 subjects. Ninety anaemic children were evaluated for the etiology of anaemia. Prevalence of anaemia, as judged by WHO recommended 'cut-off' value of haemoglobin < 11 g/dl, was 76 per cent while comparable value of 74.8 per cent was derived by response to haematinic supplementation. Pure iron deficiency anaemia (IDA) was detected in 41.4 per cent (37/90) of anaemic children. Vitamin B12 deficiency alone or in combination with iron was diagnosed in 14.4 and 22.2 per cent anaemic children respectively. Similarly folate deficiency, IDA with infection and anaemia of chronic diseases (ACD) was diagnosed in 2.2, 3.3 and 12.2 per cent cases respectively. Childhood anaemia continues to be a significant public health problem in preschoolers and iron deficiency is by far the commonest nutritional cause of anaemia. Vitamin B12 deficiency per se or in combination with iron is an important yet not commonly recognised cause of anaemias in preschool children in the community.

    Zidovudine (AZT), a nucleoside reverse transcriptase inhibitor was the first breakthrough in AIDS therapy in 1990.This study was conducted with an aim to determine prevalence of AZT induced anaemia in HIV infected patients initiated on AZT containing anti retroviral therapy(ART) regimen and also to find out any risk factor for causing AZT induced anaemia. Study was carried out in ART centre, M.K.C.G, MCH, Berhampur between Jan 2009 and Dec 2011. HIV infected patients registered at ART centre were treated according to National AIDS Control Organisation (NACO) guidelines. Patients (n = 1221) with Hb >8 gm/dl were prescribed AZT based ART regimen. Patients having anaemia (<8 gm/dl) were excluded from the study. Correlation of baseline characteristics (age, sex, weight, Hb level, CD4 count, World Health Organization (WHO) clinical stage) with risk of developing anaemia was also calculated. 178 (14.6 %) patients on AZT regimen developed anaemia. Patients with low CD4 count were more prone to develop severe anaemia. Age, sex, weight, WHO clinical stage had no relation with development of anaemia. Incidence of AZT induced anaemia was very high and patients having low CD4 count were more susceptible to develop anaemia.

    Pyridoxine, or vitamin B6, is commonly used to treat acquired idiopathic sideroblastic anaemia (AISA, including refractory anaemia with ring sideroblasts), but the efficacy of this therapy in an unselected AISA population (i.e. patients without confirmed ALAS2 or other pyridoxine-responsive germline mutations) has not been established. We reviewed clinical data from 231 patients with AISA and found that 42% of 203 evaluable patients had been treated with pyridoxine. Only 6.8% of pyridoxine-treated patients experienced a haemoglobin improvement (≥ 1.5 g/dL) meeting 2006 International Working Group for Myelodysplastic Syndromes standardised response criteria. As some patients received combination therapy with erythropoietin or other agents, improvement could be attributed to pyridoxine monotherapy in only one patient (1.4%). Smaller, less meaningful increments in haemoglobin levels of 0.5 g/dL were observed in 13.5% of patients. Response to therapy did not correlate with International Prognostic Scoring System (IPSS) risk group or multilineage vs unilineage dysplasia. New symptomatic peripheral neuropathy was noted in 2.3% of patients treated with pyridoxine. In this large series of unselected patients with sideroblastic anaemia, pyridoxine therapy was ineffective and was associated with a risk of adverse effects. Pyridoxine therapy should be reserved for patients with known or suspected pyridoxine-responsive mutations.

    Full Text Available Objective. The Third US National Health and Nutrition Examination Survey (NHANES III prompted the recognition of geriatric anaemia as a public health concern since ~10% of people aged 65 years or older were anaemic. The objective of this study was to design and implement a continuing medical education (CME event that motivates and guides Primary Care Health Practitioners (PCHPs to adopt medical practices that improve outcomes among geriatric patients with anaemia by employing effective diagnostic workup. Research design and methods. A total of 4196 PCHPs participated in 11 highly interactive 75-minute live conferences conducted throughout the US from 2011 through 2013 that featured case-based interactive discussions on the workup of microcytic, normocytic, and macrocytic anaemia by a PCHP and local haematologist expert. A standardised diagnostic algorithm for geriatric anaemia was used and distributed as a handout at the live activity. A reinforcing mobile application based on this algorithm was introduced in 2012. Main outcome measures. Data from participants were gathered immediately after the event, 10–12 weeks post-event, and 1–3 years post-event. Outcomes were evaluated according to Moore's levels. Chi-squared analyses compared the proportion of respondents who committed to one or more of the five major behavioural changes over time. Results. The Chi-squared test analysed data from each of the three timelines for five medical behavioural changes. A comparison of participants’ responses showed that there was a significant increase in the proportion of responders committing to behavioural change #1, “Avoid indiscriminant use of erythropoiesis-stimulating agents” and #5, “Refer patients with unexplained mild anaemia to a haematologist” from post-event to 1–3 years (p<0.001 (see Table 2.

    Haploinsufficiency of ribosomal proteins (RPs) and upregulation of the tumour suppressor TP53 have been shown to be the common basis for the anaemia observed in Diamond Blackfan anaemia and 5q- myelodysplastic syndrome. We previously demonstrated that treatment with L-Leucine resulted in a marked improvement in anaemia in disease models. To determine if the L-Leucine effect was Tp53-dependent, we used antisense MOs to rps19 and rps14 in zebrafish; expression of tp53 and its downstream target cdkn1a remained elevated following L-leucine treatment. We confirmed this observation in human CD34+ cells. L-Leucine thus alleviates anaemia in RP-deficient cells in a TP53-independent manner.

    In China, a full fat soy powder mixed with multiple micronutrient powders (Ying Yang Bao (YYB)) was developed, and the efficacy of YYB was shown in controlling anaemia and improving child growth and development. However, prior to 2008, there was no sustainable way to provide YYB to vulnerable populations, except through free distribution by the government. This study was to test the concept of public-private partnership (PPP) to deliver YYB and to evaluate the effectiveness of marketing YYB through PPP. Programme activities included development of a complementary food supplement (CFS) national standard, product concept test, product development and marketing, behavior change communication, monitoring and evaluation. Baseline and end-line surveys were used to evaluate product awareness, purchasing and the impacts of the project on anaemia and feeding practices. A Chinese CFS standard was approved. Caregivers and their 6- to-24-month-old children participated in the baseline (n=226) and the end-line survey (n=221). A concept test at the baseline survey showed that 78% of caregivers were willing to buy YYB at 0.1 USD. After developing the product and implementing the intervention for 8 months, 59.6% of surveyed caregivers purchased YYB. While not significant, the prevalence of anaemia was marginally lower at the end line (28.8%) than at the baseline (36.2%). For those purchasing YYB, the risk of anaemia was significantly reduced by 87% of odds (Pmarketing are identified as a prerequisite for marketing YYB or other nutritious CFS. Public and private advocacy and marketing could successfully increase awareness of YYB and access and use through market channels. The YYB project may be effective for reducing anaemia and improving feeding practices.

    Gerard J Casey

    Full Text Available BACKGROUND: To estimate the cost and cost-effectiveness of a project administering de-worming and weekly iron-folic acid supplementation to control anaemia in women of reproductive age in Yen Bai province, Vietnam. METHODS AND FINDINGS: Cost effectiveness was evaluated using data on programmatic costs based on two surveys in 2006 and 2009 and impact on anaemia and iron status collected in 2006, 2007, and 2008. Data on initial costs for training and educational materials were obtained from the records of the National Institute of Malariology, Parasitology and Entomology and the Yen Bai Malaria Control Program. Structured questionnaires for health workers at district, commune and village level were used to collect ongoing distribution and monitoring costs, and for participants to collect transport and loss of earnings costs. The cost per woman treated (defined as consuming at least 75% of the recommended intake was USD0.76 per annum. This estimate includes financial costs (for supplies, training, and costs of health care workers' time. Prevalence of anaemia fell from 38% at baseline, to 20% after 12 months. Thus, the cost-effectiveness of the project is assessed at USD 4.24 per anaemia case prevented per year. Based on estimated productivity gains for adult women, the benefit:cost ratio is 6.7∶1. Cost of the supplements and anthelminthics was 47% of the total, while costs of training, monitoring, and health workers' time accounted for 53%. CONCLUSION: The study shows that weekly iron-folic acid supplementation and regular de-worming is a low-cost and cost-effective intervention and would be appropriate for population-based introduction in settings with a high prevalence of anaemia and iron deficiency and low malaria infection rates.

  3. Fatal cold agglutinin-induced haemolytic anaemia: a case report

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available Abstract Introduction Cold agglutinin disease usually develops as a result of the production of a specific immunoglobulin M auto-antibody directed against the I/i and H antigens, precursors of the ABH and Lewis blood group substances, on red blood cells. Autoimmune and lymphoproliferative disorders, Mycoplasma pneumoniae and other infections can be associated with the production of cold agglutinins. In its classic presentation with haemolytic anaemia and Raynaud's syndrome, cold agglutinin disease is usually idiopathic. Several factors play a role in determining the ability of a cold agglutinin to induce a haemolytic anaemia such as antibody concentration and temperature range, in particular the highest temperature at which antibodies interact with red blood cells. Case presentation A 48-year-old Caucasian man presented to our hospital with symptoms of extreme asthenia caused by severe anaemia. The transfusion of red blood cells (O Rh-positive, started as prescribed by the emergency guidelines in force without pre-transfusion tests, induced fatal haemolysis because of the presence of high levels of anti-H antibodies in his blood, that reacted with the large amount of H antigen in universal (0 red blood cells. Conclusion Emergency transfusion of universal red blood cells (0 Rh-positive or negative is usually accepted by the international guidelines in force in emergency departments. In this report we describe a rare complication caused by the very high concentration in the recipient of cold agglutinins and the activation of the complement system, responsible for red blood cell lysis and consequent fatal cardiovascular shock. We conclude that emergency transfusion of universal red blood cells (0 Rh-positive or negative may be dangerous and its risk should be assessed against the risk of delaying transfusion until the pre-transfusion tests are completed.

    Radiographic findings in the sternal abnormalities are often nonspecific, showing appearances from a localized benign lesion to an aggressive lesion as seen with infections and malignant neoplasms. A specific diagnosis of sternal abnormalities can be suggested on the basis of CT and MR characteristics. Familiarity with the presentation and variable appearance of sternal abnormalities may aid the radiologist is suggesting a specific diagnosis. We present among others characteristic radiographic findings of hemangioma, chondrosarcoma, hydatid disease, and SAPHO syndrome. In those cases in which findings are not specific, cross-sectional imaging modalities may help the clinician in their management. (orig.)

    The prevalence of infants born with low cord haemoglobin (fetal anaemia) is high in areas where malaria and iron deficiency anaemia in pregnancy are common. The objective of the present study was to determine risk factors for fetal anaemia in an area of high malaria transmission in southern Malawi. A case control study was undertaken with fetal anaemia defined as cord haemoglobin (Hb) < 12.5 g/dl. Between March 1993 and July 1994, pregnant women attending the study hospitals for the first time in that pregnancy were enrolled. Data on socio-economic status, anthropometry, previous obstetric history and current pregnancy were collected. Malaria parasitaemia, Hb levels and iron status were measured in maternal blood at recruitment and delivery and in umbilical venous blood. Fetal anaemia occurred in 23.4% of babies. Mean (SD) cord Hb was 13.6 g/dl (1.83). Factors associated with fetal anaemia were: birth in the rainy season [adjusted odds ratio (AOR) 2.33, 95% CI 1.73-3.14], pre-term delivery (AOR 1.60, 1.03-2.49), infant Hb < 14 g/dl at 24 hours (AOR 2.35, 1.20-4.59), maternal Hb at delivery < 8 g/dl (AOR 1.61, 1.10-2.42) or <11 g/dl (AOR 1.60, 1.10-2.31). A higher prevalence of fetal anaemia occurred with increasing peripheral Plasmodium falciparum parasite density (p=0.03) and geometric mean placental parasite densities were higher in babies with fetal anaemia than in those without (3331 vs 2152 parasites/microl, p=0.07). Interventions should aim to reduce fetal anaemia by improving malaria and anaemia control in pregnancy and by addressing the determinants of pre-term delivery.

    The neurological condition triggered by anaesthesia with nitrous oxide involves the cyanocobalamine pathway and is characterised by progressive demyelination and axonal lesions of the peripheral nerves and cervicothoracic spinal cord (posterior and anterolateral columns) giving a peripheral neuropathy and very frequently subacute combined degeneration of the spinal cord. It is possible to show these demyelinating lesions by MRI of the spine, allowing early diagnosis and follow-up. We describe a case of myeloneuropathy with onset a few hours after nitrous oxide anaesthesia in a patient with macrocytic anaemia and possible subclinical vitamin B{sub 12} deficiency and MRI evidence of a lesion of the cervical spinal cord. Neurological and haematological improvement followed cyanocobalamine replacement. (orig.) With 2 figs., 15 refs.

    2010-11-01

    Numerous molecular abnormalities have been described in lymphomas. They are of diagnostic and prognostic value and are taken into account for the WHO classification of these tumors. They also shed some light on the underlying molecular mechanisms involved in lymphomas. Overall, four types of molecular abnormalities are involved: mutations, translocations, amplifications and deletions of tumor suppressor genes. Several techniques are available to detect these molecular anomalies: conventional cytogenetic analysis, multicolor FISH, CGH array or gene expression profiling using DNA microarrays. In some lymphomas, genetic abnormalities are responsible for the expression of an abnormal protein (e.g. tyrosine-kinase, transcription factor) detectable by immunohistochemistry. In the present review, molecular abnormalities observed in the most frequent B, T or NK cell lymphomas are discussed. In the broad spectrum of diffuse large B-cell lymphomas microarray analysis shows mostly two subgroups of tumors, one with gene expression signature corresponding to germinal center B-cell-like (GCB: CD10+, BCL6 [B-Cell Lymphoma 6]+, centerine+, MUM1-) and a subgroup expressing an activated B-cell-like signature (ABC: CD10-, BCL6-, centerine-, MUM1+). Among other B-cell lymphomas with well characterized molecular abnormalies are follicular lymphoma (BCL2 deregulation), MALT lymphoma (Mucosa Associated Lymphoid Tissue) [API2-MALT1 (mucosa-associated-lymphoid-tissue-lymphoma-translocation-gene1) fusion protein or deregulation BCL10, MALT1, FOXP1. MALT1 transcription factors], mantle cell lymphoma (cycline D1 [CCND1] overexpression) and Burkitt lymphoma (c-Myc expression). Except for ALK (anaplastic lymphoma kinase)-positive anaplastic large cell lymphoma, well characterized molecular anomalies are rare in lymphomas developed from T or NK cells. Peripheral T cell lymphomas not otherwise specified are a heterogeneous group of tumors with frequent but not recurrent molecular abnormalities

    Full Text Available Andrei Shleifer and Daniel Treisman recently rendered a summary verdict on the post Soviet Russian transition experience finding that the Federation had become a normal country with the west's assistance, and predicting that it would liberalize and develop further like other successful nations of its type. This essay demonstrates that they are mistaken on the first count, and are likely to be wrong on the second too. It shows factually, and on the norms elaborated by Pareto, Arrow and Bergson that Russia is an abnormal political economy unlikely to democratize, westernize or embrace free enterprise any time soon

    Background Clinically significant anaemia, requiring red blood cell transfusions, is frequently observed in Emergency Departments (ED). To optimise blood product use, we developed a clinical protocol for the management of iron-deficiency anaemia in a fast-track anaemia clinic within the ED. Materials and methods From November 2010 to January 2014, patients presenting with sub-acute, moderate-to-severe anaemia (haemoglobin [Hb] <11 g/dL) and confirmed or suspected iron deficiency were referred to the fast-track anaemia clinic. Those with absolute or functional iron deficiency were given intravenous (IV) ferric carboxymaltose 500–1,000 mg/week and were reassessed 4 weeks after receiving the total iron dose. The primary study outcome was the haematological response (Hb≥12 g/dL and/or Hb increment ≥2 g/dL). Changes in blood and iron parameters, transfusion rates and IV iron-related adverse drug effects were secondary outcomes. Results Two hundred and two anaemic patients with iron deficiency (150 women/52 men; mean age, 64 years) were managed in the fast-track anaemia clinic, and received a median IV iron dose of 1,500 mg (1,000–2,000 mg). Gastro-intestinal (44%) or gynaecological (26%) bleeding was the most frequent cause of the anaemia. At follow-up (183 patients), the mean Hb increment was 3.9±2.2 g/dL; 84% of patients were classified as responders and blood and iron parameters normalised in 90%. During follow-up, 35 (17%) patients needed transfusions (2 [range: 1–3] units per patient) because they had low Hb levels, symptoms of anaemia and/or were at risk. Eight mild and one moderate, self-limited adverse drug effects were witnessed. Discussion Our data support the feasibility of a clinical protocol for management of sub-acute anaemia with IV iron in the ED. IV iron was efficacious, safe and well tolerated. Early management of anaemia will improve the use of blood products in the ED. PMID:26674819

    Full Text Available ABSTRACT: Anaemia is a very common problem in our country and iron deficiency is the most common cause especially in the adolescent age group o f girls .Auto-immune haemolytic anaemia (AIHA is an acquired type of haemolytic anaemia, ca used by autoantibodies directed against the red cells. We hereby report a cross sectional study of chronic severe anaemia, which presented to our hospital for evaluation.5 patients o f the 36 patients evaluated over a period of 3 months were found to have a haemolytic anaemia.2 patients had beta thalassemia minor and 3 patients had autoimmune haemolytic anaemia with wa rm antibodies. Treatment with prednisolone resulted in significant improvement of t he haematological parameters in these 3 patients along with blood transfusion. Alternative a etiological causes of anaemia should be considered in patients with microcytic hypochromic an aemia for proper management of patients.

    Full Text Available Background. Maternal anaemia is a worldwide public health problem affecting particularly developing countries. In Burkina Faso, little data is available for rural areas. This study aimed to determine the prevalence of maternal anaemia and the risk factors associated with it in the rural health district of Hounde in Burkina Faso but also to define better control measures of maternal anaemia. Methods. This cross-sectional study conducted in 2010 had a sample of 3,140 pregnant women attending antenatal care in all the 18 primary health care facilities of the district. The women’s characteristics and their knowledge about contraceptives and sexually transmitted infections (STI were collected. Also, physical and gynaecological examination, completed by vaginal, cervix, blood, and stool samplings, were collected. Results. A prevalence of 63.1% was recorded for maternal anaemia. Geophagy rate was 16.3% and vitamin A deficiency 69.3%. In addition, anaemia was independently associated with low education, low brachial perimeter, geophagy, and primigravida. But no statically significant relationship was found between maternal anaemia and infectious diseases or vitamin A deficiency. Conclusion. The magnitude of maternal anaemia was found to be higher in rural Hounde health district and should be addressed by adequate policy including education and the fight against malnutrition.

    Haemolytic anaemia is often induced following prolonged exposure to chemical substances. Currently, under EU Council Directive 67/548/EEC, substances which induce such effects are classified as dangerous and assigned the risk phrase R48 'Danger of serious damage to health by prolonged exposure.' Whilst the general classification criteria for this endpoint are outlined in Annex VI of this Directive, they do not provide specific information to assess haemolytic anaemia. This review produced by the EU Working Group on Haemolytic Anaemia provides a toxicological assessment of haemolytic anaemia and proposes criteria that can be used in the assessment for classification of substances which induce such effects. An overview of the primary and secondary effects of haemolytic anaemia which can occur in rodent repeated dose toxicity studies is given. A detailed analysis of the toxicological significance of such effects is then performed and correlated with the general classification criteria used for this endpoint. This review intends to give guidance when carrying out an assessment for classification for this endpoint and to allow for better transparency in the decision-making process on when to classify based on the presence of haemolytic anaemia in repeated dose toxicity studies. The extended classification criteria for haemolytic anaemia outlined in this review were accepted by the EU Commission Working Group on the Classification and Labelling of Dangerous Substances in September 2004.

    Anaemia is a major public health problem in India. Although nearly three quarters of the Indian population live in rural areas, the epidemiology of anaemia in rural settings is not well known. We performed a retrospective observational study using routine clinical data from patients attending the out-patient clinics of a rural hospital in India from June 2011 to August 2014. The study included 73,795 determinations of haemoglobin. 49.5% of patients were female. The median haemoglobin concentration was 11.3 g/dL (interquartile range (IQR), 9.8-12.4) in females and 12.5 g/dL (IQR, 10.6-14.2) in males. Anaemia was present in the majority of children older adults. Children iron deficiency was the main cause of anaemia. However, the prevalence of normocytic anaemia increased with age. The results of this study can be used by public health programmes to design target interventions aimed at reducing the huge burden of anaemia in India. Further studies are needed to clarify the aetiology of anaemia among older adults.

    Full Text Available BACKGROUND In this tertiary care hospital, one of the common condition of all the patients attending the hospital is Anaemia, which is a decrease in haemoglobin content or decrease in haematocrit below the lower limit of the 95% reference range for the individual’s age and sex. The patient presents with varied symptoms of different grades, depending on the severity of anaemia, in different clinical settings. Common presenting symptoms of anaemia are generalised weakness, malaise, loss of appetite and muscular pains. METHODS All the patient samples received at the central laboratory for haemogram, complete blood counts and peripheral smear examination over the period of two years between June 2014 to May 2016 were included in the study. Anaemia cases were diagnosed depending on the criteria of the definition of anaemia, and morphological typing of anaemia was done based on the peripheral smear examination of all the cases with decreased haemoglobin level. Standard cell counter was used to estimate the Hb and other red cell indices, and corroborated with peripheral blood smear examination by standard Romanowsky stains. RESULTS A total of 810 cases of anaemia were diagnosed over the period of two years, of which morphological typing yielded 685 cases of Microcytic and hypochromic anaemia, 15 cases of Dimorphic anaemia, 22 cases of Macrocytic anaemia and 88 cases of Normocytic and normochromic anaemia. CONCLUSION Anaemia is one of the most common problems of patients attending this tertiary care hospital, and detection and morphological typing of anaemia is very helping in guiding the clinicians in diagnosis and further management of anaemias for better patient care.

    Full Text Available Background: About one-third of the global population is anaemic. WHO has estimated that prevalence of anaemia in pregnant women is 18% in developed countries and relatively high 56% in developing countries. Prevalence of anaemia in South East Asian countries is highest in the world. WHO estimates that even among the South East Asian countries, India has the highest prevalence of anaemia. Aims & Objectives: To determine the prevalence of anaemia among pregnant women and to determine association of anaemia with its socio-demographic factors. Material & Methods: A descriptive cross sectional study was conducted among pregnant women 2nd trimester onwards who came to ante natal clinic of obstetrics and gynaecology department during January-March 2014 by using pre-designed, pretested schedule. A total of 300 pregnant women were clinically examined. Written consent was taken. Haemoglobin estimation was done by Cyanmethaemoglobin method and anaemia was graded according to WHO criteria. Statistical analysis was done using Microsoft Excel 2007 and SPSS Version 17. Results: Overall prevalence of anaemia among the pregnant women was found to be 58.3%. It was seen that 31% of women were illiterate and 38.7% of them belong to upper middle class. Factors such as level of education of women, occupation and consumption of Iron Folic Acid were found to be significantly associated with prevalence of anaemia in pregnancy. Conclusion: A very high prevalence of anaemia in pregnancy needs awareness about late marriage, birth spacing, one or two child norm, antenatal care, green leafy vegetable in diet, mandatory regular supply of IFA tablets to adolescent and pregnant women along with correction of other nutritional deficiencies.

    Treatment of anaemia in patients with chronic heart failure (CHF) and reduced left ventricular ejection fraction has traditionally focused on erythropoietin-stimulating agents. However, recent studies have shown that treatment with intravenous (IV) iron can improve the symptoms and quality of life in patients with CHF and iron deficiency (ID), with or without anaemia. The management of ID is becoming an important therapeutic target in patients with CHF, and in this article, we will review iron metabolism in the context of anaemia and heart failure. We will also focus on the importance of diagnosing and treating ID, preferably with IV iron preparations, in patients with CHF.

    Full Text Available This study examines the relative importance of living in an urban versus rural setting and malaria in contributing to the public health problem of malarial anaemia (MA and anaemia respectively in apparently healthy primary school children.A cross-sectional study was conducted among 727 school children aged between four and 15 years living in an urban (302 and rural (425 settings in the Mount Cameroon area. Blood sample collected from each child was used for the preparation of blood films for detection of malaria parasites and assessment of malaria parasite density as well as full blood count determination using an automated haematology analyzer. Based on haemoglobin (Hb measurements, children with malaria parasitaemia were stratified into MA (Hb<11 g/dL; mild MA (Hb of 8-10.9 g/dL; moderate MA (Hb of 6.1-7.9 g/dL and severe MA (Hb≤6 g/dL. Evaluation of potential determinants of MA and anaemia was performed by multinomial logistic-regression analysis and odds ratios used to evaluate risk factors.Out of the 727 children examined, 72 (9.9% had MA. The prevalence of MA and anaemia were significantly higher (χ2 = 36.5, P <0.001; χ2 = 16.19, P <0.001 respectively in children in the urban (17.9%; 26.8% respectively than in the rural area (4.2%; 14.8% respectively. Majority of the MA cases were mild (88.9%, with moderate (5.6% and severe MA (5.6% occurring in the urban area only. The age group ≤6 years was significantly (P <0.05 associated with both MA and anaemia. In addition, low parasite density was associated with MA while malaria parasite negative and microcytosis were associated with anaemia.Malarial anaemia and anaemia display heterogeneity and complexity that differ with the type of settlement. The presence of severe MA and the contributions of the age group ≤6 years, low parasite density and microcytosis to the public health problem of MA and anaemia are noteworthy.

    Iron is essential for organisms. It is mainly utilized in mitochondria for biosynthesis of iron-sulfur clusters, hemes and other cofactors. Mitoferrin 1 and mitoferrin 2, two homologues proteins belonging to the mitochondrial solute carrier family, are required for iron delivery into mitochondria. Mitoferrin 1 is highly expressed in developing erythrocytes which consume a large amount of iron during hemoglobinization. Mitoferrin 2 is ubiquitously expressed, whose functions are less known. Zebrafish with mitoferrin 1 mutation show profound hypochromic anaemia and erythroid maturation arrests, and yeast with defects in MRS3/4, the counterparts of mitoferrin 1/2, has low mitochondrial iron levels and grows poorly by iron depletion. Mitoferrin 1 expression is up-regulated in yeast and mouse models of Fiedreich's ataxia disease and in human cell culture models of Parkinson disease, suggesting its involvement in the pathogenesis of diseases with mitochondrial iron accumulation. In this study we found that reduced mitoferrin levels in C. elegans by RNAi treatment causes pleiotropic phenotypes such as small body size, reduced fecundity, slow movement and increased sensitivity to paraquat. Despite these abnormities, lifespan was increased by 50% to 80% in N2 wild type strain, and in further studies using the RNAi sensitive strain eri-1, more than doubled lifespan was observed. The pathways or mechanisms responsible for the lifespan extension and other phenotypes of mitoferrin RNAi worms are worth further study, which may contribute to our understanding of aging mechanisms and the pathogenesis of iron disorder related diseases.

    HIV infected patients are frequently exposed to anaemia, due to antiretroviral agents and/or prophylactic treatment of opportunistic infections. Anemia due to PICA, unusually evoked in our western countries, could be a more frequent situation than imagined. We report two cases of fluctuating anemia with no HIV or iatrogenic origin, observed in two HIV infected women, 47 years old and 33 years old respectively, coming from Africa and treated with antiretroviral agents. The anemia was explained by a culturally sanctioned practice of kaolin ingestion, in the broader context of PICA and resolved after the withdrawal of kaolin ingestion. PICA, and in particular kaolin ingestion, must be investigated when HIV infected patients came from Africa and presented significative unexplained anemia.

    Full Text Available Inosine triphosphatase (ITPA single nucleotide polymorphisms (SNPs are strongly associated with protection against ribavirin (RBV-induced anaemia in European, American and Asian patients; however, there is a paucity of data for Brazilian patients. The aim of this study was to evaluate the ITPA SNP (rs7270101/rs1127354 frequency in healthy and hepatitis C virus (HCV-infected patients from Brazil and the association with the development of severe anaemia during antiviral therapy. ITPA SNPs were determined in 200 HCV infected patients and 100 healthy individuals by sequencing. Biochemical parameters and haemoglobin (Hb levels were analysed in 97 patients who underwent antiviral therapy. A combination of AArs7270101+CCrs1127354 (100% ITPase activity was observed in 236/300 individuals. Anaemia was observed in 87.5% and 86.2% of treated patients with AA (rs7270101 and CC genotypes (rs1127354, respectively. Men with AA (rs7270101 showed a considerable reduction in Hb at week 12 compared to those with AC/CC (p = 0.1475. In women, there was no influence of genotype (p = 0.5295. For rs1127354, men with the CC genotype also showed a sudden reduction in Hb compared to those with AC. Allelic distribution of rs7270101 and rs1127354 shows high rates of the genotypes AA and CC, respectively, suggesting that the study population had a great propensity for developing RBV-induced anaemia. A progressive Hb reduction during treatment was observed; however, this reduction was greater in men at week 12 than in women.

    Wilson's disease can have different manifestations like jaundice, cirrhosis of liver, extrapyramidal symptoms and dementia. Haemolytic anaemia may occur but it is commonly associated with florid manifestation of liver disease. Sometimes, liver cell necrosis can release huge free copper ions in blood, giving rise to oxidant damage to erythrocytes. Oxidative damage to cell membrane, haemoglobin and erythrocyte metabolism causes haemolytic crisis. In some cases, liver involvement is subclinical, but nonetheless, free copper is released from necrosed hepatocytes and causes oxidative damage to erythrocytes.We had two cases of Wilson's disease with initial presentation as severe haemolytic anaemia and no other clinical feature suggestive of Wilson's disease was present. In unclear cause of haemolytic anaemia, especially in adolescents or young adults, Wilson's disease should be considered. As Wilson disease is rare and its initial presentation with haemolytic anaemia is rarer, high level of suspicion is required to diagnose it.

    Background The association of anaemia with intestinal schistosomiasis and hookworm infections are poorly explored in populations that are not limited to children or pregnant women. Methods We sampled 1,832 individuals aged 5–90 years from 30 communities in Mayuge District, Uganda. Demographic, village, and parasitological data were collected. Infection risk factors were compared in ordinal logistic regressions. Anaemia and infection intensities were analyzed in multilevel models, and population attributable fractions were estimated. Findings Household and village-level predictors of Schistosoma mansoni and hookworm were opposite in direction or significant for single infections. S. mansoni was found primarily in children, whereas hookworm was prevalent amongst the elderly. Anaemia was more prevalent in individuals with S. mansoni and increased by 2.86 fold (p-value<0.001) with heavy S. mansoni infection intensity. Individuals with heavy hookworm were 1.65 times (p-value = 0.008) more likely to have anaemia than uninfected participants. Amongst individuals with heavy S. mansoni infection intensity, 32.0% (p-value<0.001) of anaemia could be attributed to S. mansoni. For people with heavy hookworm infections, 23.7% (p-value = 0.002) of anaemia could be attributed to hookworm. A greater fraction of anaemia (24.9%, p-value = 0.002) was attributable to heavy hookworm infections in adults (excluding pregnant women) as opposed to heavy hookworm infections in school-aged children and pregnant women (20.2%, p-value = 0.001). Conclusion Community-based surveys captured anaemia in children and adults affected by S. mansoni and hookworm infections. For areas endemic with schistosomiasis or hookworm infections, WHO guidelines should include adults for treatment in helminth control programmes. PMID:26513151

    Full Text Available Abstract Background Early diagnosis of anaemia represents an important task within primary care settings. This study reports on the frequency of new cases of anaemia among patients attending rural primary care settings in Crete (Greece and to offer an estimate of iron deficiency anaemia (IDA frequency in this study group. Methods All patients attending the rural primary health care units of twelve general practitioners (GPs on the island of Crete for ten consecutive working days were eligible to participate in this study. Hemoglobin (Hb levels were measured by portable analyzers. Laboratory tests to confirm new cases of anaemia were performed at the University General Hospital of Heraklion. Results One hundred and thirteen out of 541 recruited patients had a low value of Hb according to the initial measurement obtained by the use of the portable analyzer. Forty five (45.5% of the 99 subjects who underwent laboratory testing had confirmed anaemia. The mean value of the Hb levels in the group with confirmed anaemia, as detected by the portable analyzer was 11.1 g/dl (95% Confidence Interval (CI from 10.9 to 11.4 and the respective mean value of the Hb levels obtained from the full blood count was 11.4 g/dl (95% CI from 11.2 to 11.7 (P = 0.01. Sixteen out of those 45 patients with anaemia (35.6% had IDA, with ferritin levels lower than 30 ng/ml. Conclusion Keeping in mind that this paper does not deal with specificity or sensitivity figures, it is suggested that in rural and remote settings anaemia is still invisible and point of care testing may have a place to identify it.

    Full Text Available It is quite unbelievable but significant percentage of young healthy women is at risk of anaemia despite proper nutritional state. In this study we decided to determine the lack or excess of which nutrients in a diet can lead to any effects. The major cause of anaemia is not, as in many studies on nutritional status, the deficiency in iron in a diet. Iron intake in women with anaemia exceeded AI (Adequate Intake level. 120 people took part in the study. Average HGB concentration in female group amounted to 12.45 g/dL and in male group to 14.35 g/dL. Anaemia was determined in 29% women and 4.2% men. In group of women with anaemia a statistically higher intake of SFA, cholesterol, and sucrose and lower intake of pyridoxine, folacin, niacin, and vitamin E, Mn, Cu, Zn, Fe, and Mg were determined. In a group of men with low haemoglobin concentration a statistically higher intake of sucrose but lower intake of fat, especially SFA and MUFA, vitamin C and zinc were observed. Therefore, together with anaemia in the group of women there are coexisting deficiencies in other nutrients, as compared to the group of men. Prevention in both groups should include various supplements.

    The present study investigates the socioeconomic risk factors of anaemia among women belonging to eastern Indian states. An attempt has been made to find out differences in anaemia related to social class and place of residence, and age and marital status. It was hypothesized that rural women would have a higher prevalence of anaemia compared with their urban counterparts, particularly among the poorest social strata, and that ever-married women would be at elevated risk of anaemia compared with never-married women, particularly in the adolescent age group. Using data from National Family Health Survey-3, 2005-6, a nationally representative cross-sectional survey that provided information on anaemia level among 19,695 women of this region, the present study found that the prevalence of anaemia was high among all women cutting across social class, location and other attributes. In all 47.9% were mildly anaemic (10.0-11.9.9 g/dl), 16.1% were moderately anaemic (7.0-9.9 g/dl) and 1.6% were severely anaemic (educational attainment, mass media exposure and high socioeconomic status. Urban poor women and adolescent ever-married women had very high odds of being anaemic. New programme strategies are needed, particularly those that improve iron storage and enhance the overall nutritional status of women throughout the life-cycle.

    A 60-year-old woman was diagnosed with non-severe aplastic anaemia when she presented with anaemia and thrombocytopenia. She developed recurrent life-threatening hypotensive reactions during transfusion of leukodepleted platelet concentrates, and washed platelet concentrates prevented the development of such reactions subsequently. A paroxysmal nocturnal haemoglobinuria clone was detected on investigating for aplastic anaemia, which has been speculated to play a role in the recurrent hypotensive reactions.

    Full Text Available Microalbuminuria is a pre-clinical marker of renal damage in children with sickle cell anaemia and can predict renal failure. Reported prevalence rates increased with age. In Nigeria, burden of disease and prevailing poor health facilities necessitate its screening, determination of prevalence and associated risk factors. It is a cross-sectional as well as descriptive study. Screening microalbuminuria used subjects’ early morning urine. Socio-demographic as well as clinical details were ascertained using semi-structured questionnaires and case files. Associations and statistical relationship of prevalence rates and clinical/epidemiological data were ascertained using chi-squared and multivariate analysis . Two hundred children with sickle cell anaemia (4–17 years in steady state and 200 age/gender-matched controls were enrolled. Prevalence of microalbuminuria was ,respectively, 18.5% and 2.5% for subjects and controls . Microalbuminuria was commoner in females (19.8% than males (17.4% , increased with age , significantly associated with haemoglobin level and hospitalizations (0.001. Subjects had normal renal function. Hospitalizations and haemoglobin levels showed statistical significance on multivariate analysis. Prevalence of microalbuminuria is 18.5%. Age, haemoglobin concentrations, and higher hospitalizations influenced microalbuminuria among subjects. Screening for microalbuminuria should be incorporated in the case management of subjects with identified risk factors.

    2003-01-01

    Infectious salmon anaemia (ISA) is a major disease of Atlantic salmon, Salmo salar, caused by an orthomyxovirus (ISAV). Increases in global aqua culture and the international movement of fish made it important to determine if Pacific salmon are at risk. Steelhead trout, Oncorhynchus mykiss, and chum, O. keta, Chinook, O. tshawytscha, coho, O. kisutch, and Atlantic salmon were injected intraperitoneally with a high, medium, or low dose of a Norwegian strain of ISAV. In a second challenge, the same species, except chum salmon, were injected with a high dose of either a Canadian or the Norwegian strain. Average cumulative mortality of Atlantic salmon in trial 1 was 12% in the high dose group, 20% in the medium dose group and 16% in the low dose group. The average cumulative mortality of Atlantic salmon in trial 2 was 98%. No signs typical of ISA and no ISAV-related mortality occurred among any of the groups of Oncorhynchus spp. in either experiment, although ISAV was reisolated from some fish sampled at intervals post-challenge. The results indicate that while Oncorhynchus spp. are quite resistant to ISAV relative to Atlantic salmon, the potential for ISAV to adapt to Oncorhynchus spp. should not be ignored.

    Full Text Available Aim. We determined the prevalence of anaemia and evaluated markers of iron homeostasis in a cohort of HIV patients. Methods. A comparative cross-sectional study on 319 participants was carried out at the Tamale Teaching Hospital from July 2013 to December 2013, 219 patients on HAART (designated On-HAART and 100 HAART-naive patients. Data gathered include sociodemography, clinical history, and selected laboratory assays. Results. Prevalence of anaemia was 23.8%. On-HAART participants had higher CD4/CD3 lymphocyte counts, Hb, HCT/PCV, MCV, MCH, iron, ferritin, and TSAT (P<0.05. Hb, iron, ferritin, and TSAT decreased from grade 1 to grade 3 anaemia and CD4/CD3 lymphocyte count was lowest in grade 3 anaemia (P<0.05. Iron (P=0.0072 decreased with disease severity whilst transferrin (P=0.0143 and TIBC (P=0.0143 increased with disease severity. Seventy-six (23.8% participants fulfilled the criteria for anaemia, 86 (26.9% for iron deficiency, 41 (12.8% for iron deficiency anaemia, and 17 (5.3% for iron overload. The frequency of anaemia was higher amongst participants not on HAART (OR 2.6 for grade 1 anaemia; OR 3.0 for grade 3 anaemia. Conclusion. In this study population, HIV-associated anaemia is common and is related to HAART status and disease progression. HIV itself is the most important cause of anaemia and treatment of HIV should be a priority compared to iron supplementation.

    Full Text Available Anaemia is known to have an impact on child development and mortality and is a severe public health problem in most countries in sub-Saharan Africa. We investigated the consistency between ecological and individual-level approaches to anaemia mapping by building spatial anaemia models for children aged ≤15 years using different modelling approaches. We aimed to (i quantify the role of malnutrition, malaria, Schistosoma haematobium and soil-transmitted helminths (STHs in anaemia endemicity; and (ii develop a high resolution predictive risk map of anaemia for the municipality of Dande in northern Angola. We used parasitological survey data for children aged ≤15 years to build Bayesian geostatistical models of malaria (PfPR≤15, S. haematobium, Ascaris lumbricoides and Trichuris trichiura and predict small-scale spatial variations in these infections. Malnutrition, PfPR≤15, and S. haematobium infections were significantly associated with anaemia risk. An estimated 12.5%, 15.6% and 9.8% of anaemia cases could be averted by treating malnutrition, malaria and S. haematobium, respectively. Spatial clusters of high risk of anaemia (>86% were identified. Using an individual-level approach to anaemia mapping at a small spatial scale, we found that anaemia in children aged ≤15 years is highly heterogeneous and that malnutrition and parasitic infections are important contributors to the spatial variation in anaemia risk. The results presented in this study can help inform the integration of the current provincial malaria control programme with ancillary micronutrient supplementation and control of neglected tropical diseases such as urogenital schistosomiasis and STH infections.

    In the experiment for the determination of the gravitational constant G, we found an abnormal vibrational mode of the torsion pendulum. The abnormal mode disappeared as a magnetic damper was introduced to the torsion pendulum system. Our experimental results also show that the magnetic damper can be used to suppress the high frequency vibrational noises to torsion pendulums effectively.

    2015-02-01

    Anaemia is common in patients with cardiac disease and also in those undergoing cardiac surgery. There is increasing evidence that preoperative anaemia is associated with increased patient morbidity and mortality following surgery. We performed a systematic literature review to assess the impact of anaemia and intravenous (IV) iron supplementation on outcomes in cardiac surgery. Sixteen studies examined preoperative anaemia in detail. One study examined the role of preoperative IV iron administration and a further three, the effect of postoperative iron supplementation on haemoglobin (Hb) levels and the need for transfusion. Preoperative anaemia was associated with higher mortality, more postoperative blood transfusions, longer intensive care unit (ICU) and total hospital stay and also a greater incidence of postoperative cardiovascular events. In the single study that examined preoperative IV iron in combination with erythropoietin treatment, there was decreased blood transfusion, shorter hospital stay and an increase in patient survival. However, this was a small retrospective cohort study, with the observation and treatment groups analysed over different time periods. Postoperative administration of IV iron therapy, either alone or in combination with erythropoietin, was not effective in raising Hb levels or reducing red cell concentrate transfusion. On the basis of currently available evidence, the effect of perioperative administration of IV iron to cardiac surgery patients, alone or in combination with erythropoietin, remains unproven. Well-designed and appropriately powered prospective randomized controlled trials are needed to evaluate perioperative iron supplementation in the context of cardiac surgery.

    Abnormal protein aggregation or amyloid is the major cause ofmany neurodegenerative disorders. The present review focuses on the correlation between sequence and structure features of proteins related to the diseases and abnormal protein aggregation. Recent progress has improved our knowledge on understand-ing the mechanism of amyloid formation. We suggest a nucleation model for ordered protein aggregation, which can also explain pathogenesis mechanisms of these neurodegenerative diseases in vivo.

    This study was undertaken to determine the teratogenic potential of methylmercury on chick embryogenesis. Methylmercuric chloride was dissolved in sodium bicarbonate (0.2%) and administered to the chick embryos at doses ranging from 0.0009 to 0.010 mg per egg. The injections were made at days 2 and 3 on incubation (Groups A and B). All the embryos including controls were examined on the 7th day of incubation. Methylmercury poisoning was observed to be both embryolethal and teratogenic. Within the two groups, embryolethality was higher in Group A. The following congenital abnormalities were observed: exencephaly, shortened and twisted limbs, microphthalmia, shortened and twisted neck, beak abnormalities, everted viscera, reduced body size and hemorrhage all over the body. Exencephaly and limb abnormalities were very common. No differences in the incidence and types of gross abnormalities within both the groups (A and B) were noted. The incidence of malformations among the controls was low. The results of present investigation show that methylmercury poisoning is both embryolethal and teratogenic to early chick embryogenesis.

    We retrospectively analysed routinely collected baseline data of 2252 patients with HIV infection registered in the National Free Antiretroviral Treatment Program in Xinjiang province, China, from 2006 to 2011 to estimate the prevalence and predictors of anaemia at the initiation of combined antiretroviral therapy. Anaemia was diagnosed using the criteria set forth by the World Health Organisation, and univariate and multivariate logistic regression analyses were performed to determine its predictors. The prevalences of mild, moderate, and severe anaemia at the initiation of combined antiretroviral therapy were 19.2%, 17.1%, and 2.6%, respectively. Overall, 38.9% of the patients were anaemic at the initiation of combined antiretroviral therapy. The multivariate logistic regression analysis indicated that Uyghur ethnicity, female gender, lower CD4 count, lower body mass index value, self-reported tuberculosis infection, and oral candidiasis were associated with a higher prevalence of anaemia, whereas higher serum alanine aminotransferase level was associated with a lower prevalence of anaemia. The results suggest that the overall prevalence of anaemia at the initiation of combined antiretroviral therapy in patients with HIV infection is high in Xinjiang, China, but severe anaemia is uncommon. Patients in China should be routinely checked for anaemia prior to combined antiretroviral therapy initiation, and healthcare providers should carefully select the appropriate first-line combined antiretroviral therapy regimens for anaemic patients.

    Introduction Nutritional status during adolescence plays an important role in the human lifecycle that influences growth and development and during this period nutrient needs are the greatest. The objective of this study is to assess anaemia and nutritional status of adolescent girls in the Babile district, Eastern Ethiopia. Methods Data were collected from 547 adolescent aged 10-19 years by cross sectional study design. WHO Anthro-plus software was used to analyse Nutritional statuses of adolescents and magnitudes were determined using WHO 2007 references point. Haemoglobin was measured on site by hem cue machine. Descriptive and inferential statistical analysis was carried out depending on the nature of variables. Results The result of the study show that 21.6% thin, 4.8% were over weighted and 1.1% was obese, 32% were anaemic and 15% of adolescents were stunted/ short stature than normal. Nutritional status of adolescent were low both in urban and rural adolescents, but severe thinness were higher among of rural (39.3%) compared to urban (37.5%) adolescents. Factors independently associated with stunting were place of residence, father occupation source of drinking water and age of the adolescents. Conclusion Nutritional status of adolescent girls contributes to the nutritional status of the community. There is a need to initiate intervention measures to improve the nutritional status of adolescent girls who are the future ‘mothers-to-be’. Hence, there is a need to create awareness among adolescents and their family about nutrition and health. PMID:27642403

    Polychlorinated biphenyls (PCBs), persistent chemicals widely used for industrial purposes, have been banned in most parts of the world for decades. Owing to their bioaccumulative nature, PCBs are still found in high concentrations in marine mammals, particularly those that occupy upper trophic positions. While PCB-related health effects have been well-documented in some mammals, studies among dolphins and whales are limited. We conducted health evaluations of bottlenose dolphins (Tursiops truncatus) near a site on the Georgia, United States coast heavily contaminated by Aroclor 1268, an uncommon PCB mixture primarily comprised of octa- through deca-chlorobiphenyl congeners. A high proportion (26%) of sampled dolphins suffered anaemia, a finding previously reported from primate laboratory studies using high doses of a more common PCB mixture, Aroclor 1254. In addition, the dolphins showed reduced thyroid hormone levels and total thyroxine, free thyroxine and triiodothyronine negatively correlated with PCB concentration measured in blubber (p = 0.039, dolphins when compared with previously sampled reference sites, and therefore probably did not contribute to the observed correlations. Our results clearly demonstrate that dolphins are vulnerable to PCB-related toxic effects, at least partially mediated through the endocrine system. The severity of the effects suggests that the PCB mixture to which the Georgia dolphins were exposed has substantial toxic potential and further studies are warranted to elucidate mechanisms and potential impacts on other top-level predators, including humans, who regularly consume fish from the same marine waters.

    Full Text Available Abstract Infectious salmon anaemia virus (ISAV, a member of the Orthomyxoviridae family, infects and causes disease in farmed Atlantic salmon (Salmo salar L.. Previous studies have shown Atlantic salmon endothelial cells to be the primary targets of ISAV infection. However, it is not known if cells other than endothelial cells play a role in ISAV tropism. To further assess cell tropism, we examined ISAV infection of Atlantic salmon gill epithelial cells in vivo and in vitro. We demonstrated the susceptibility of epithelial cells to ISAV infection. On comparison of primary gill epithelial cell cultures with ISAV permissive fish cell cultures, we found the virus yield in primary gill epithelial cells to be comparable with that of salmon head kidney (SHK-1 cells, but lower than TO or Atlantic salmon kidney (ASK-II cells. Light and transmission electron microscopy (TEM revealed that the primary gill cells possessed characteristics consistent with epithelial cells. Virus histochemistry showed that gill epithelial cells expressed 4-O-acetylated sialic acid which is recognized as the ISAV receptor. To the best of our knowledge, this is the first demonstration of ISAV infection in Atlantic salmon primary gill epithelial cells. This study thus broadens our understanding of cell tropism and transmission of ISAV in Atlantic salmon.

    Objectives: To find out the preva-lence of worm infestation and anaemia among pregnant women along with their socio-demographic characteristics, dietary habits and state of personal hygiene and elicit the association, if any, with anemia and worm infestation Materials and methods: A cross-sectional study was carried out among pregnant mothers attending the antenatal clinic at Nasibpur Union Health Center. All antenatal mothers who came for antenatal checkup for the first time to the health centre on two prefixed days of the week during the study period were interviewed. The reports of their stool and haemoglobin examination were followed up. Results: 82% of the pregnant women were suffering from anemia.25% of the study population had worm infestation. Age at marriage, green leafy vegetable, fruit and flesh food intake of at least 4 days a week, use of lemon with food most of the time, avoiding the practice of eating last in the family, handwashing with soap and water before eating and use of footwear outside the house were statically significant with hemoglobin concentration. Only religion and handwashing practice with soap and water before eating had statistically significant association with worm infestation. Conclusion: The study showed that certain protective factors like diet and personal hygiene if addressed at the time of antenatal checkup can reduce the number of cases of anemia significantly.

Recent advances in molecular biology have made it possible to investigate the relationship between the FA genotype and the nature and severity of the clinical phenotype. The treatment of FA is also the object of intense research that is currently centred on the transplant of hematopoyetic progenitors, especially successful in cases of an HLA-identical brother or sister donor, and in gene therapy, which is still in the phase of clinical research.

  4. Can an integrated approach reduce child vulnerability to anaemia? Evidence from three African countries.

    Directory of Open Access Journals (Sweden)

    Kendra Siekmans

    Full Text Available Addressing the complex, multi-factorial causes of childhood anaemia is best done through integrated packages of interventions. We hypothesized that due to reduced child vulnerability, a "buffering" of risk associated with known causes of anaemia would be observed among children living in areas benefiting from a community-based health and nutrition program intervention. Cross-sectional data on the nutrition and health status of children 24-59 mo (N=2405 were obtained in 2000 and 2004 from program evaluation surveys in Ghana, Malawi and Tanzania. Linear regression models estimated the association between haemoglobin and immediate, underlying and basic causes of child anaemia and variation in this association between years. Lower haemoglobin levels were observed in children assessed in 2000 compared to 2004 (difference -3.30 g/L, children from Tanzania (-9.15 g/L and Malawi (-2.96 g/L compared to Ghana, and the youngest (24-35 mo compared to oldest age group (48-59 mo; -5.43 g/L. Children who were stunted, malaria positive and recently ill also had lower haemoglobin, independent of age, sex and other underlying and basic causes of anaemia. Despite ongoing morbidity, risk of lower haemoglobin decreased for children with malaria and recent illness, suggesting decreased vulnerability to their anaemia-producing effects. Stunting remained an independent and unbuffered risk factor. Reducing chronic undernutrition is required in order to further reduce child vulnerability and ensure maximum impact of anaemia control programs. Buffering the impact of child morbidity on haemoglobin levels, including malaria, may be achieved in certain settings.

    Trichuris dysentery syndrome is caused by Trichuris trichiura which contributes to one of the most common helminthic infections in the world. It is associated with heavy colonic infection that manifests as mucoid diarrhoea, rectal bleeding, rectal prolapse, iron deficiency anaemia, and finger clubbing. Here, we report a case of trichuris dysentery syndrome complicated with severe chronic iron deficiency anaemia in a 4-year-old girl who required blood transfusion. The nematode was visualized on stool microscopic and colonoscopic examination. A longer duration of anti-helminthic treatment is required to achieve effective and better outcome.

    Conclusions: Anaemia in pregnancy is associated with several social and demographic factors. Strategies must be taken from the conceptional level itself by providing proper antenatal counseling and women should be economically empowered and good antenatal care must be made available and accessible to all of them. Even with routine iron prophylaxis in pregnancy, still the prevalence of anaemia is high, so should we consider one or two doses of routine parenteral iron therapy for all pregnant women?

    Autoimmune haemolytic anaemia (AIHA) in mantle cell lymphoma (MCL) is a rare but life-threatening complication. To date, there are no relevant data for treatment of AIHA in MCL. Ibrutinib, which has been approved for relapse/refractory MCL, is an immunomodulatory drug inhibiting Th2 activation and consequently the production of autoantibodies. We report a case of MCL with AIHA in which this form of anaemia was not controlled with the usual chemotherapy. Ibrutinib was used when MCL with AIHA relapsed, and it allowed rapid remission of AIHA and rapid discontinuation of steroid therapy.

    Plasma was collected from Atlantic salmon Salrno salar with acute infectious salmon anaemia (ISA) and used to challenge Atlantic salmon parr by intraperitoneal injection. Treatment of plasma with the lipid solvent, chloroform, showed that the etiological agent of ISA contained essential lipids, probably as a viral envelope. Some infectivity remained following treatment with freon. Injection challenges using fractions from equilibrium density gradient centrifugation of plasma from fish with acute ISA revealed a band of infectivity in the range 1.184 to 1.262 g cm-3. The band was believed to conta~n both complete ISA-virus particles and infectious particles lacking a complete envelope, nucleocapsid or genome. Density gradient centrifugation of infectious plasma for enrichment of the putative ISA virus appeared to offer a suitable method for obtaining virus-specific nucleic acid for use in the construction of cDNA libraries.

    Hair shaft disorders may lead to brittleness and uncombable hair. In general the hair feels dry and lusterless. Hair shaft abnormalities may occur as localized or generalized disorders. Genetic predisposition or exogenous factors are able to produce and maintain hair shaft abnormalities. In addition to an extensive history and physical examination the most important diagnostic examination to analyze a hair shaft problem is light microscopy. Therapy of hair shaft disorders should focus to the cause. In addition, minimizing traumatic influences to hair shafts, such as dry hair with an electric dryer, permanent waves and dyes is important. A short hair style is more suitable for such patients with hair shaft disorders.

    Twenty-seven consecutive Italian patients with Fanconi's anaemia (FA) underwent stem cell transplantation (SCT) from an HLA-matched related donor in 10 Italian centres of the Associazione Italiana Ematologia ed Oncologia Pediatrica (AIEOP), Gruppo Italiano di Trapianto di Midollo Osseo (GITMO). Twenty-two patients (81.5%) were conditioned with low-dose (median 20 mg/kg) cyclophosphamide (Cy) and thoraco-abdominal or total body irradiation (median dose 500 cGy), five patients (18.5%) with high-dose Cy (median 120 mg/kg). Graft-vs.-host disease (GVHD) prophylaxis was carried out with cyclosporin A in 26 cases; methotrexate (MTX) was added in eight cases. One patient received MTX alone. The median follow-up was 36 months. Ninety-two percent of patients (25 out of 27) engrafted, grade II and III acute GVHD occurred in 28% and 8% of patients, respectively, with chronic GVHD in 12.5%. Conditioning-related toxicity was mild: 4% of patients had grade III mucositis, 7.4% had grade II haemorrhagic cystitis, 14.8% had grade III liver toxicity and 11.1% had grade III renal toxicity. Transplant-related mortality at 12 months was 19.2%, survival at 36 months was 81.5%, with a median Karnofsky score of 100%. No late tumours occurred after a mean follow-up of the survivors of 5 years. None of the studied variables significantly affected the survival, including conditioning regimen, acute GVHD and clinical non-haematological phenotype. Among the studied variables, only conditioning regimens containing high-dose Cy and the presence of genital abnormalities were significantly (P < 0.05) associated with an increased rate of acute GVHD. Our study demonstrates that the Italian FA patients undergoing SCT from an HLA-matched related donor have a very good outcome. These patients, when compared with others of different ethnic origin who underwent allogeneic bone marrow transplantation, showed a less severe non-haematological phenotype, raising the possibility that this milder phenotype may

  14. Anaemia in diabetic renal failure: is there a role for early erythropoietin treatment in preventing cardiovascular mortality?

    2008-09-01

    The mortality rate in diabetics with chronic kidney disease (CKD) is seven times higher than end-stage renal disease mainly because of cardiac causes. Anaemia may have a relevant role in the pathogenesis of cardiovascular (CV) disease in CKD. Anaemia occurs at an earlier stage of CKD in diabetic individuals than in those with other causes of CKD. Observational findings support the unfavourable influence of anaemia on mortality in CKD patients, and the combination of anaemia and CKD in diabetics identifies a group with a particularly high mortality risk. While the effect of erythropoietin on these patients' quality of life is known, its impact on mortality and CV risk is uncertain. The recent Anaemia Correction in Diabetes (ACORD) trial in diabetic CKD patients, which targeted haemoglobin levels of 13-15 mg/dl, disclosed no statistically significant favourable or adverse effects on mortality or morbidity over the 2-year follow-up, while other studies endeavouring to nearly normalize haemoglobin have reportedly proved risky. Even if anaemia is causally involved, the pathogenesis of CV disease in diabetics with CKD is so complex that addressing just one factor (anaemia) may not suffice to prevent CV risk, and normalizing haemoglobin levels may even be harmful.

    Pernicious anaemia is a common autoimmune disorder with a prevalence of approximately 4% amongst Europeans. If untreated, it can result in permanent neurological disability or death. Central to the diagnosis is establishing the presence of vitamin B12 deficiency. Concern has been raised recently regarding false-normal results obtained with competitive-binding vitamin B12 assays performed on automated biochemistry platforms in patients with pernicious anaemia due to the presence of interfering anti-intrinsic factor antibodies in the patient sample. We report a case in which diagnosis of pernicious anaemia was delayed due to false-normal vitamin B12 results. Questioning the results in light of high pre-test probability, and knowledge of the role of functional markers of vitamin B12 deficiency enabled the correct diagnosis to be made so that effective treatment could be initiated. It is crucial that those who frequently request vitamin B12 are aware of the potential problems with the available assays and how these problems can be addressed. We suggest that all patients with normal vitamin B12 levels where there is a high clinical suspicion for deficiency such as a macrocytic anaemia, neurological symptoms or megaloblastic bone marrow should have a functional assay of vitamin B12 (plasma homocysteine or methylmalonic acid) checked to further investigate for vitamin B12 deficiency.

    Full Text Available Many patients with pernicious anaemia are treated with lifelong intramuscular vitamin B12 replacement. As early as the 1950s, there were studies suggesting that oral vitamin B12 replacement may provide adequate absorption. Nevertheless, oral vitamin B12 replacement in patients with pernicious anaemia remains uncommon in clinical practice. The objective of this review is to provide an update on the effectiveness of oral vitamin B12 for the treatment of pernicious anaemia, the recommended dosage and the required frequency of laboratory test and clinical monitoring. Relevant articles were identified by PubMed search from 1 January 1980 to 31 March 2016 and through hand search of relevant reference articles. Two randomised controlled trials, three prospective papers, one systematic review and three clinical reviews fulfilled our inclusion criteria. We found that oral vitamin B12 replacement at 1000mcg daily was adequate to replace vitamin B12 levels in patients with pernicious anaemia. We conclude that oral vitamin B12 is an effective alternative to vitamin B12 intramuscular injections. Patients should be offered this alternative after an informed discussion on the advantages and disadvantages of both treatment options.

  4. Subclinical anaemia of chronic disease in adult patients with cystic fibrosis.

    Patients with chronic hypoxaemia develop secondary polycythaemia that improves oxygen-carrying capacity. Therefore, normal haemoglobin and haematocrit values in the presence of chronic arterial hypoxaemia in cystic fibrosis constitute \\'relative anaemia\\'. We sought to determine the cause of this relative anaemia in patients with cystic fibrosis. We studied haematological indices and oxygen saturation in healthy volunteers (n=17) and in adult patients with cystic fibrosis (n=15). Patients with cystic fibrosis had lower resting arterial oxygen saturation when compared with normal volunteers (P<0.0001), and exercise led to a greater reduction in arterial oxygen saturation (P<0.0001). However, haemoglobin and haematocrit values in patients with cystic fibrosis did not significantly differ from normal volunteers. Serum iron (P=0.002), transferrin (P=0.02), and total iron-binding capacity (P=0.01) were lower in patients with cystic fibrosis. There were no significant differences in serum ferritin, percentage iron saturation, serum erythropoietin or red cell volume between the groups. The data presented demonstrate a characteristic picture of anaemia of chronic disease in adult patients with cystic fibrosis, except for normal haemoglobin and haematocrit values. Normal haemoglobin and haematocrit values in patients with cystic fibrosis appear to represent a combination of the effects of arterial hypoxaemia promoting polycythaemia, counterbalanced by chronic inflammation promoting anaemia of chronic disease.

    Background CD4+ T cells play a crucial role in the pathogenesis of aplastic anaemia. However, the mechanisms of over-proliferation, activation, infiltration of bone marrow and damage to haematopoietic cells of CD4+ T cells in aplastic anaemia are unclear. Therefore, we screened differentially expressed genes of bone marrow CD4+ T cells of aplastic anaemia patients and normal donors by suppressive subtractive hybridization to investigate the pathogenesis of aplastic anaemia.Methods The bone marrow mononuclear cells of a first visit aplastic anaemia patient and a healthy donor of the same age and sex were isolated using lymphocyte separating medium by density gradient centrifugation. With the patients as "tester" and donor as "driver", their CD4+T cells were separated with magnetic bead sorting and a cDNA library established by suppressive subtractive hybridization. Then 15 of the resulting subtracted cDNA clones were randomly selected for DNA sequencing and homological analysis. With semiquantitative RT-PCR, bone marrow samples from 20 patients with aplastic anaemia and 20 healthy donors assessed the expression levels of differentially expressed genes from SSH library.Results PCR detected 89 clones in the library containing an inserted fragment of 100 bp to 700 bp. Among 15 sequenced clones, 12 were known genes including 3 repeated genes. Compared with normal donors, there were 9/12 genes over-expressed in bone marrow CD4+T cells of patients with aplastic anaemia. The effects of these genes included protein synthesis, biology oxidation, signal transduction, proliferative regulation and cell migration. Not all these genes had been reported in the mechanisms of haematopoietic damage mediated by CD4+ T cells in aplastic anaemia.Conclusions Screening and cloning genes, which regulate functions of CD4+ T cells, are helpful in elucidating the mechanisms of over proliferation, activation, infiltrating bone marrow and damaging haematopoietic cells of CD4+ T cells in

  7. Schistosoma mansoni Infections, Undernutrition and Anaemia among Primary Schoolchildren in Two Onshore Villages in Rorya District, North-Western Tanzania

    Science.gov (United States)

    2016-01-01

    Background Undernutrition and anaemia remains to be a major public health problem in many developing countries, where they mostly affect children. Intestinal parasitic infections are known to affect both growth and haemoglobin levels. Much has been reported on the impact of geohelminths on anaemia and undernutrition, leaving that of Schistosoma mansoni not well studied. Therefore this study intended to determine the association between S.mansoni infections, anaemia and undernutrition among schoolchildren in Rorya district, Northwestern Tanzania. Methodology A cross-sectional study was carried among schoolchildren in two onshore villages namely Busanga and Kibuyi in Rorya district. Single stool specimens were collected from 513 randomly selected schoolchildren and processed for microscopic examination using the Kato-Katz method. Nutritional status was determined by anthropometry. Blood samples were also collected and examined for malaria parasites and haemoglobin levels using the Giemsa stain and HaemoCue methods, respectively. A pretested questionnaire was used to collect socio-demographic data and associated factors. Results The prevalence of S. mansoni infection and malaria was 84.02% and 9.16%, respectively. Other parasites found were Ascaris lumbricoides (1.36%) and Hookworm (1.36%). The prevalence of stunting and wasting was 38.21% and 14.42%, respectively. The prevalence of anaemia was 29.43%, whereby 0.58% had severe anaemia. S. mansoni infection was not found to be associated with undernutrition or anaemia (p>0.05). The risk of stunting and wasting increased with increasing age (p<0.001). Anaemia was associated with age, sex and village of residence (p<0.05). Conclusions S.mansoni, undernutrition and anaemia are highly prevalent in the study area. The observed rates of undernutrition and anaemia were seen not to be associated with S.mansoni infection suggesting possibly being a result of poor dietary nutrients. This study suggests that policy makers should

    Full Text Available BACKGROUND: Studies conducted in high income countries have shown that anaemia is a common medical condition among older people, but such data are scarce in Africa. The objectives of this study were to estimate the prevalence, types, risk factors and clinical correlates of anaemia in older people. METHODS: Participants were aged (≥ 50 years recruited from a general population cohort from January 2012 to January 2013. Blood samples were collected for assessing hemoglobin, serum ferritin, serum vitamin B12, serum folate, C-reactive protein, malaria infection and stool samples for assessment of hookworm infection. HIV status was assessed using an algorithm for HIV rapid testing. Questionnaires were used to collect data on sociodemographic characteristics and other risk factors for anaemia. RESULTS: In total, 1449 people participated (response rate 72.3%. The overall prevalence of anaemia was 20.3 % (95% CI 18.2-22.3%, and this was higher for males (24.1%, 95% CI=20.7-27.7% than females (17.5%, 95% CI=15.0-20.1%. In males, the prevalence of anaemia increased rapidly with age almost doubling between 50 and 65 years (p-trend<0.001. Unexplained anaemia was responsible for more than half of all cases (59.7%. Anaemia was independently associated with infections including malaria (OR 3.49, 95% CI 1.78-6.82, HIV (OR 2.17, 1.32-3.57 heavy hookworm infection (OR 3.45, 1.73-6.91, low fruit consumption (OR 1.55, 1.05-2.29 and being unmarried (OR 1.37 , 95% CI 1.01-1.89. However, the odds of anaemia were lower among older people with elevated blood pressure (OR 0.47, 95% CI 0.29-0.77. CONCLUSION: Anaemia control programmes in Uganda should target older people and should include interventions to treat and control hookworms and educational programs on diets that enhance iron absorption. Clinicians should consider screening older people with HIV or malaria for anaemia. Further studies should be done on unexplained anaemia and serum ferritin levels that predict

    Full Text Available BACKGROUND: Given that micronutrient deficiency, neglected intestinal parasitic infections (IPIs and poor socioeconomic status are closely linked, we conducted a cross-sectional study to assess the relationship between IPIs and nutritional status of children living in remote and rural areas in West Malaysia. METHODS/FINDINGS: A total of 550 children participated, comprising 520 (94.5% school children aged 7 to 12 years old, 30 (5.5% young children aged 1 to 6 years old, 254 (46.2% boys and 296 (53.8% girls. Of the 550 children, 26.2% were anaemic, 54.9% iron deficient and 16.9% had iron deficiency anaemia (IDA. The overall prevalence of helminths was 76.5% comprising Trichuris trichiura (71.5%, Ascaris lumbricoides (41.6% and hookworm infection (13.5%. It was observed that iron deficiency was significantly higher in girls (p = 0.032 compared to boys. Univariate analysis demonstrated that low level of mother's education (OR = 2.52; 95% CI = 1.38-4.60; p = 0.002, non working parents (OR = 2.18; 95% CI = 2.06-2.31; p = 0.013, low household income (OR = 2.02; 95% CI = 1.14-3.59; p = 0.015, T. trichiura (OR = 2.15; 95% CI = 1.21-3.81; p = 0.008 and A. lumbricoides infections (OR = 1.63; 95% CI = 1.04-2.55; p = 0.032 were significantly associated with the high prevalence of IDA. Multivariate analysis confirmed that low level of mother's education (OR = 1.48; 95 CI% = 1.33-2.58; p<0.001 was a significant predictor for IDA in these children. CONCLUSION: It is crucial that a comprehensive primary health care programme for these communities that includes periodic de-worming, nutrition supplement, improved household economy, education, sanitation status and personal hygiene are taken into consideration to improve the nutritional status of these children.

  13. Candidate gene sequencing of SLC11A2 and TMPRSS6 in a family with severe anaemia: common SNPs, rare haplotypes, no causative mutation.

    Directory of Open Access Journals (Sweden)

    Anita Kloss-Brandstätter

    Full Text Available BACKGROUND: Iron-refractory iron deficiency anaemia (IRIDA is a rare disorder which was linked to mutations in two genes (SLC11A2 and TMPRSS6. Common polymorphisms within these genes were associated with serum iron levels. We identified a family of Serbian origin with asymptomatic non-consanguineous parents with three of four children presenting with IRIDA not responding to oral but to intravenous iron supplementation. After excluding all known causes responsible for iron deficiency anaemia we searched for mutations in SLC11A2 and TMPRSS6 that could explain the severe anaemia in these children. METHODOLOGY/RESULTS: We sequenced the exons and exon-intron boundaries of SLC11A2 and TMPRSS6 in all six family members. Thereby, we found seven known and fairly common SNPs, but no new mutation. We then genotyped these seven SNPs in the population-based SAPHIR study (n = 1,726 and performed genetic association analysis on iron and ferritin levels. Only two SNPs, which were top-hits from recent GWAS on iron and ferritin, exhibited an effect on iron and ferritin levels in SAPHIR. Six SAPHIR participants carrying the same TMPRSS6 genotypes and haplotype-pairs as one anaemic son showed lower ferritin and iron levels than the average. One individual exhibiting the joint SLC11A2/TMPRSS6 profile of the anaemic son had iron and ferritin levels lying below the 5(th percentile of the population's iron and ferritin level distribution. We then checked the genotype constellations in the Nijmegen Biomedical Study (n = 1,832, but the profile of the anaemic son did not occur in this population. CONCLUSIONS: We cannot exclude a gene-gene interaction between SLC11A2 and TMPRSS6, but we can also not confirm it. As in this case candidate gene sequencing did not reveal causative rare mutations, the samples will be subjected to whole exome sequencing.

Methods: 76 patients hospitalised for HF were studied. Of these patients, 31 were anaemic. BNP and NT - proBNP levels were measured in all patients before discharge. Blood routine test and renal function test were also carried out on these patients. Results: 1. NT - proBNP levels had no difference in the patients with a-naemia and patients without anaemia (P >0. 05) . BNP level of anaemia patients was signifcantly higher than that in patients without anaemia(P <0. 05) . 2. Pearson analysis showed plasma haemoglobin level had negative correlation with the levels of BNP. Conclusion: These results indicate that anaemia should be taken into consideration during the interpretation of BNP and NT - proBNP levels in HF patients.

    BACKGROUND: Some studies have suggested that helminth infections increase the risk of malaria infection and are associated with increased number of malaria attacks and anaemia. Thus interventions to control helminth infections may have an impact on incidence of clinical malaria and anaemia....... The current study assessed the impact of two anthelmintic treatment approaches on malaria infection and on anaemia in school and pre-school children in Magu district, Tanzania. METHODS: A total of 765 children were enrolled into a prospective randomized anthelmintic intervention trial following a baseline...... parasites. There was no significant difference in malaria infection (prevalence, parasite density and frequency of malaria attacks) and in the prevalence of anaemia between the repeated and single dose anthelmintic treatment groups at 12 and 24 months follow up (p>0.05). However, overall...

    BACKGROUND: Preoperative anaemia is a well-established risk factor for use of blood transfusions and postoperative morbidity. Consequently, focus on preoperative evaluation of haemoglobin levels is increasing. In this context, iron deficiency anaemia may be a symptom of undiscovered...... gastrointestinal (GI) cancer requiring further investigation. However, the association between preoperative anaemia and cancer 1 year after elective total hip (THA) and total knee arthroplasty (TKA) is unknown. We evaluated 1-year cancer diagnoses, particularly GI cancers, in anaemic and non-anaemic THA and TKA......·3%) and 79 (1·6%) new cancers in anaemic and non-anaemic patients, respectively (OR: 1·38; 95% CI: 0·81-2·35, P = 0·228).

    Anaemia is a negative prognostic factor for patients with heart failure and impaired renal function, but its role in stroke patients is unknown. Furthermore, anaemia has been shown to influence the level of N-terminal pro-brain natriuretic peptide (NT-proBNP), but this is only investigated...... in patients with heart failure, not in stroke patients. Two-hundred-and-fifty consecutive, well-defined ischemic stroke patients were investigated. Mortality was recorded at 6 months follow-up. Anaemia was diagnosed in 37 patients (15%) in whom stroke severity was worse than in the non-anaemic group, whilst...... the prevalence of renal affection, smoking and heart failure was lower. At 6 months follow-up, 23 patients were dead, and anaemia had an odds ratio of 4.7 when adjusted for age, Scandinavian Stroke Scale and a combined variable of heart and/or renal failure and/or elevation of troponin T using logistic...

    Patients diagnosed with severe aplastic anaemia and without a compatible bone marrow transplant donor are treated with immunosuppressive therapy. These patients are found with time to develop a clonal disease such as myelodysplasia or paroxysmal nocturnal haemoglobinuria. However, the development of plasma cell dyscrasias is rare. We report the case here of a patient treated with immunosuppressive therapy who went on to develop myeloma 11 months after being diagnosed with severe aplastic anaemia. We include here a review of the literature. PMID:28275389

    2009-01-01

    BACKGROUND: The simultaneous occurrence of cardiovascular disease (CVD), kidney disease, and anaemia is associated with increased morbidity and mortality. In the community setting, little data exists about the risk associated with milder levels of anaemia when it is present concurrently with CVD and chronic kidney disease (CKD). The aim of this study was to establish the prevalence of CKD and anaemia in patients with CVD in the community and to examine whether the presence of anaemia was associated with increased morbidity and mortality. METHODS: This study was designed as a retrospective cohort study and involved a random sample of 35 general practices in the West of Ireland. A practice-based sample of 1,609 patients with established cardiovascular disease was generated in 2000\\/2001 and followed for five years. The primary endpoint was death from any cause. Statistical analysis involved using one-way ANOVA and Chi-squared tests for baseline data and Cox proportional-hazards models for mortality data. RESULTS: Of the study sample of 617 patients with blood results, 33% (n = 203) had CKD while 6% (n = 37) had CKD and anaemia. The estimated risk of death from any cause, when compared to patients with cardiovascular disease only, was almost double (HR = 1.98, 95% CI 0.99 to 3.98) for patients with both CVD and CKD and was over 4 times greater (HR = 4.33, 95% CI 1.76 to 10.68) for patients with CVD, CKD and anaemia. CONCLUSION: In patients with cardiovascular disease in the community, chronic kidney disease and anaemia occur commonly. The presence of chronic kidney disease carries an increased mortality risk which increases in an additive way with the addition of anaemia. These results suggest that early primary care diagnosis and management of this high risk group may be worthwhile.

    Objective: To investigate the prevalence and socio-demographic factors associated with iron deficiency anaemia among blood donors in Sokoto, North Western, Nigeria using a combination of haemoglobin haematocrit and serum ferritin measurements. Methods: One hundred and fifty consecutively recruited whole blood donors, comprising of 148 (98.7%) family replacement donors and 2 (1.3%) voluntary non-remunerated donors aged 18-60 years and mean age 39±21 years constituted the subjects for this study. The full blood count was carried out using Mythic 22 CT fully automated haematology analyser (Orphee SA, Switzerland). Serum was tested for ferritin using a human ferritin enzyme immunoassay kit-ACCU Diag™ ELISA Ferritin kit (Diagnostic Automation/Cortez Diagnostic Inc. California, USA). Results: The prevalence of anaemia (haemoglobin<11.0 g/dL) was evident in 24 (16%) and iron deficiency anaemia (serum ferritin<12 ng/mL+haemoglobin<11 g/dL) in 5 (10%) of donors. The haemoglobin and ferritin levels was significantly lower among regular voluntary remunerated blood donors (13.50±0.00 and 34.88±0.00) compared to family replacement donors (14.10±2.40 and 74.12±45.20) respectively (P=0.01 and 0.05 respectively). The mean haemoglobin and ferritin level was compared among donors based on gender. The haemoglobin and ferritin was significantly higher among male donors (14.20±2.00, 78.02±49.10) compared to female donors (12.35±2.5 and 42.20±32.13) (P=0.01). The mean haemoglobin and ferritin level was compared among donors based on occupational groups. The haemoglobin and ferritin was significantly higher among civil servants compared to farmers and students (P=0.01). Conclusions: Iron deficiency anaemia is prevalent among blood donors in Sokoto, North Western, Nigeria. There is need to include routine ferritin in the blood donor testing protocol in the area to enable the diagnosis of donors with latent iron deficiency anaemia to facilitate iron supplementation for regular

    Sonoluminescence is a complex phenomenon, the mechanism of which remains unclear. The present study reveals that an abnormal ionization process is likely to be present in the sonoluminescing bubble. To fit the experimental data of previous studies, we assume that the ionization energies of the molecules and atoms in the bubble decrease as the gas density increases and that the decrease of the ionization energy reaches about 60%-70% as the bubble flashes, which is difficult to explain by using previous models.

    Embryo sac abortion is one of the major masons for sterility in indicaljaponica hybrids In rice. To clarify the causal mechanism of embryo sac abortion, we studied the female gametophyte development in two indicaljaponica hybrids via an eosin B staining procedure for embryo sac scanning using confocal laser scanning microscope. Different types of abnormalities occurred during megasporogenesis and megagamatogenesis were demonstrated. The earliest abnormality was observed in the megasporocyte. A lot of the chalazal-most megaspores were degenerated before the mono-nucleate embryo sac stage. Disordered positioning of nucleus and abnormal nucallus tissue were characteristics of the abnormal female gametes from the mono-nucleate to four-nucleate embryo sac stages. The abnormalities that occurred from the early stage of the eight-nucleate embryo sac development to the mature embryo sac stage were characterized by smaller sizes and wrinkled antipodals. Asynchronous nuclear migration, abnormal positioning of nucleus, and degeneration of egg apparatus were also found at the eight-nucleate embryo sac stage. The abnormalities that occurred during female gametophyte development resulted in five major types of abnormal embryo sacs. These abnormal embryo sacs led to abnormal fertilization. Hand pollination using normal pollens on the spikelets during anthesis showed that normal pollens could not exclude the effect of abnormal embryo sac on seed setting.

    Full Text Available Fanconi anaemia (FA is a recessive autosomal disease determined by mutations in genes of at least eleven complementation groups, with distinct distributions in different populations. As far as we know, there are no reports regarding the molecular characterisation of the disease in unselected FA patients in Brazil. OBECTIVE: This study aimed to investigate the most prevalent mutations of FANCA and FANCC genes in Brazilian patients with FA. METHODS: Genomic DNA obtained from 22 racially and ethnically diverse unrelated FA patients (mean age ± SD: 14.0 ± 7.8 years; 10 male, 12 female; 14 white, 8 black was analysed by polymerase chain reaction and restriction site assays for identification of FANCA (delta3788-3790 and FANCC (delta322G, IVS4+4A -> T, W22X, L496R, R548X, Q13X, R185X, and L554P gene mutations. RESULTS: Mutations in FANCA and FANCC genes were identified in 6 (27.3% and 14 (63.6% out of 22 patients, respectively. The disease could not be attributed to the tested mutations in the two remaining patients enrolled in the study (9.1%. The registry of the two most prevalent gene abnormalities (delta3788-3790 and IVS4 + 4 -> T revealed that they were present in 18.2% and 15.9% of the FA alleles, respectively. Additional FANCC gene mutations were found in the study, with the following prevalence: delta322G (11.4%, W22X (9.1%, Q13X (2.3%, L554P (2.3%, and R548X (2.3% of total FA alleles. CONCLUSION: These results suggest that mutations of FANCA and FANCC genes are the most prevalent mutations among FA patients in Brazil.

    We examined the morphological and functional characteristics of erythroblasts derived from marrow erythroid progenitor cells grown in a methylcellulose microculture, which were taken from a female child with rare atypical sideroblastic anaemia (SA) partially responsive to pyridoxine. Colony formation was within the normal range in three successive cultures (median values: 82.25 CFU-E and 16.4 BFU-E derived colonies/6.6 X 10(4) cells) compared to growth by normal cells (65-315 CFU-E and 9-40 BFU-E). We evaluated in vitro differentiation by biochemical microassay of a cytosol enzyme involved in the haem pathway: uroporphyrinogen I synthase (UROS). The UROS values in the erythroid colonies from SA marrow were at the lowere end of the normal range (median values: 6.7 +/- 0.3 and 14.4 +/- 3.8 pmol uroporphyrinogen/h in CFU-E and BFU-E-derived colonies respectively versus 17.4 +/- 7.3 and 25 +/- 7.2 pmol/h in CFU-E and BFU-E colonies from normal subjects. Ultrastructural examination of the SA erythroblasts from non-cultured bone marrow or derived from cultured BFU-E revealed the characteristic deposition of iron in mitochondria around the nucleus of most cells (ringed sideroblasts). However, the majority of cultured cells had marked dyserythropoietic features, with a large number of bilobulated or trilobulated erythroblasts, multiple cytoplasmic vacuoles, numerous abnormalities of the nucleus, and excessive membrane material beneath the plasma membrane, all features difficult to observe in non-cultured marrows.

    Automatic abnormality detection in video sequences has recently gained an increasing attention within the research community. Although progress has been seen, there are still some limitations in current research. While most systems are designed at detecting specific abnormality, others which...... are capable of detecting more than two types of abnormalities rely on heavy computation. Therefore, we provide a framework for detecting abnormalities in video surveillance by using multiple features and cascade classifiers, yet achieve above real-time processing speed. Experimental results on two datasets...... show that the proposed framework can reliably detect abnormalities in the video sequence, outperforming the current state-of-the-art methods....

    2016-08-01

    The identification process based on measuring the level of haemoglobin and the classification of red blood cells using microscopic examination of blood smears is the principal way to diagnose anaemia. This paper presents a proposed algorithm for detecting some anaemia types like sickle and elliptocytosis and trying to count them with healthy ones in human red blood smears based on the circular Hough transform and some morphological tools. Some cells with unknown shapes (not platelets or white cells) also have been detected. The extracted data from the detection process has been analyzed by neural network. The experimental results have demonstrated high accuracy, and the proposed algorithm has achieved the highest detection of around 98.9% out of all the cells in 27 microscopic images. Effectiveness rates up to 100%, 98%, and 99.3% have been achieved by using neural networks for sickle, elliptocytosis and cells with unknown shapes, respectively.

  11. Clinically and/or Serologically Misleading Findings Surrounding Immune Haemolytic Anaemias.

    Science.gov (United States)

    Salama, Abdulgabar

    2015-09-01

    Autoimmune haemolytic anaemias (AIHAs) are well-characterized disorders. They can be differentiated from one another and from other non-immune haemolytic anaemias by clinical, laboratory and serological testing. However, several misleading clinical presentations and/or serological findings may result in misinterpretation, delay and/or misdiagnosis. Such failures are avoidable by adequate clinical and serological experience of the responsible physicians and serologists or, at least, by an optimised bidirectional communication. As long as this has not been achieved, unpleasant failures are to be expected. A true diagnosis of AIHA can neither be verified by clinical nor serological findings alone. Thus, a collective clinical and serological picture remains obligatory for fulfilling the criteria of optimal diagnosis and therapy. Ultimately, the majority of pioneer scientific and practical work in this field stems from scientists who were simultaneously involved in both the clinic and serology.

    Necrotizing fasciitis (NF) is an uncommon soft-tissue infection in children that carries a high mortality rate. We present a 15-year-old girl with chronic pancytopenia secondary to Fanconi anaemia who developed extensive NF of the lower limb, which unfortunately resulted in a fatal outcome. Immunodeficiency is a known risk factor for the development of this condition. The findings in this case demonstrate that patients with Fanconi anaemia may be susceptible to NF and that the clinical course may be more aggressive due to underlying immunosuppression. Prompt diagnosis of NF is vital in order to initiate appropriate treatment and to optimize patient outcome. Radiological investigation demonstrated extensive soft-tissue gas and destruction affecting the entire lower limb, abdominal wall and retroperitoneum, which led to timely definitive diagnosis and management.

    Recurrent gastrointestinal haemorrhage is an uncommon manifestation of systemic sclerosis. We report a case of gastrointestinal bleeding due to gastric antral vascular ectasia (GAVE) in a patient with systemic sclerosis. Failure to recognise the condition as a cause of gastrointestinal bleeding may delay the instigation of appropriate treatment. GAVE should be considered in the differential diagnosis of anaemia in patients with autoimmune conditions such as systemic sclerosis and primary biliary cirrhosis.

In healthy people, electrophysiological data show that beta band oscillations in sensorimotor cortex decrease during movement execution (event-related beta desynchronisation (ERBD, then increase above baseline for a short time after the movement (post-movement beta rebound (PMBR; whilst in visual cortex, gamma oscillations are increased throughout stimulus presentation. In this study, we used a self-paced visuomotor paradigm and magnetoencephalography (MEG to contrast these responses in patients with schizophrenia and control volunteers. We found significant reductions in the peak-to-peak change in amplitude from ERBD to PMBR in schizophrenia compared with controls. This effect was strongest in patients who made fewer movements, whereas beta was not modulated by movement in controls. There was no significant difference in the amplitude of visual gamma between patients and controls. These data demonstrate that clear abnormalities in basic sensorimotor processing in schizophrenia can be observed using a very simple MEG paradigm.

    Full Text Available The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.

    The auditory function of sixty two Kenyan sickle cell anaemia patients aged seven to thirty years was compared to age-matched fifty five healthy controls with haemoglobin AA. Sensorineural hearing loss of 30 db and above was demonstrated in 25 (40%) of sickle cell anaemia patients and in three (5.5%) control subjects. Both sexes were equally affected. Bilateral lesion registered in 16%. Hearing threshold level was normal in 97% of the sickle cell group. High frequencies were commonly affected with hearing loss of 30-40 db. Two cases with severe unilateral deafness at all frequencies had severe recruitment suggestive of cochlea lesion. There were no cases of acoustic reflex decay in all study patients. The hearing loss was of slow onset. The high risk of deafness in Kenyan sickle cell anaemia patients may be a reflection of the severe course of the disease due to specific Kenyan haematological profile (haplotype 20 with low Hb F level), the level of medical care available and the geographical distribution in the tropics together with other factors.

    Full Text Available Background: Anaemia in pregnancy accounts for one fifth of maternal death worldwide. The association between anaemia and adverse pregnancy outcome, higher incidence of preterm & low birth weight deliveries has been demonstrated. However, nutritional anaemia in pregnancy remains one of the India’s major public health problems, despite of the fact that this problem is largely preventable. Objective: To determine the prevalence of anaemia in pregnant women and to determine association of anaemia and socio-demographic factors. Methodology: A descriptive cross sectional study was conducted among pregnant women who came to outpatient unit of obstetrics and gynecology department during March- May 2013 by using pre-designed, pretested structured schedule. Written consent was taken. Hemoglobin estimation was done by Sahli’s method and anaemia was graded according to WHO criteria. Statistical analysis was done using Microsoft Excel 2007 and SPSS Version 20. Result: - Overall prevalence of anaemia among the pregnant women was found to be 63%.It was seen that 23% of women were illiterate and 58.7% of them belong to upper lower class. Factors such as level of education of women, occupation, age at first pregnancy and consumption of Iron Folic Acid were found to be significantly associated with prevalence of anae-mia in pregnancy. Conclusion: - A very high prevalence of anaemia in pregnancy needs mandatory regular supply of IFA tablets to adolescent and pregnant women along with correction of other nutritional deficiencies and timely intervention for reducing the burden of related diseases.

    The aim of this retrospective study was to assess prevalence, risk factors, clinical presentation and outcome of phenobarbitone induced haematological abnormalities (PBIHA) in dogs. The medical records of two veterinary referral institutions were searched for dogs diagnosed with idiopathic epilepsy and treated with PB as monotherapy or polytherapy between March 2003 and September 2010. Sixteen dogs had PBIHA; the median age at diagnosis was 69.5 months. Phenobarbitone was administered at a median dose of 3 mg/kg twice a day for a median period of 100.5 days and the median serum phenobarbitone level was 19 μg/ml. Two dogs had neutropenia, three had anaemia and thrombocytopenia, two had anaemia and neutropenia; the remaining nine had pancytopenia. All dogs were referred for non-specific clinical signs. Phenobarbitone was discontinued after diagnosis, and the median time to resolution of PBIHA was 17 days. The prevalence and risk factors for PBIHA were evaluated from a questionnaire survey of referring practices to obtain more detailed follow-up on cases diagnosed with idiopathic epilepsy. The prevalence rate of PBIHA was 4.2%, and the condition occurred in dogs treated with standard therapeutic doses often within the first three months after starting treatment. Serial haematological evaluations should be therefore considered from the beginning of phenobarbitone therapy to allow early diagnosis and treatment of PBIHA.

    Full Text Available BACKGROUND: In malaria endemic countries, children who have experienced an episode of severe anaemia are at increased risk of a recurrence of anaemia. There is a need to find ways of protecting these at risk children from malaria and chemoprevention offers a potential way of achieving this objective. METHODS: During the 2003 and 2004 malaria transmission seasons, 1200 Gambian children with moderate or severe anaemia (Hb concentration <7 g/dL were randomised to receive either monthly sulfadoxine-pyrimethamine (SP or placebo until the end of the malaria transmission season in which they were enrolled, in a double-blind trial. All study subjects were treated with oral iron for 28 days and morbidity was monitored through surveillance at health centres. The primary endpoint was the proportion of children with moderate or severe anaemia at the end of the transmission season. Secondary endpoints included the incidence of clinical episodes of malaria during the surveillance period, outpatient attendances, the prevalence of parasitaemia and splenomegaly, nutritional status at the end of the malaria transmission season and compliance with the treatment regimen. RESULTS: The proportions of children with a Hb concentration of <7 g/dL at the end of the malaria transmission season were similar in the two study groups, 14/464 (3.0% in children who received at least one dose of SP and 16/471 (3.4% in those who received placebo, prevalence ratio 0.89 (0.44,1.8 P = 0.742. The protective efficacy of SP against episodes of clinical malaria was 53% (95% CI 37%, 65%. Treatment with SP was safe and well tolerated; no serious adverse events related to SP administration were observed. Mortality following discharge from hospital was low among children who received SP or placebo (6 in the SP group and 9 in the placebo group respectively. CONCLUSIONS: Intermittent treatment with SP did not reduce the proportion of previously anaemic children with moderate or severe anaemia

  7. Fetal calcifications are associated with chromosomal abnormalities.

    Directory of Open Access Journals (Sweden)

    Ellika Sahlin

    Full Text Available The biological importance of calcifications occasionally noted in fetal tissues (mainly liver at autopsy or ultrasound is largely unexplored. Previous reports hint at an association to infection, circulatory compromise, malformations or chromosomal abnormalities. To identify factors associated with calcifications, we have performed a case-control study on the largest cohort of fetuses with calcifications described thus far.One-hundred and fifty-one fetuses with calcifications and 302 matched controls were selected from the archives of the Department of Pathology, Karolinska University Hospital. Chromosome analysis by karyotyping or quantitative fluorescence-polymerase chain reaction was performed. Autopsy and placenta reports were scrutinized for presence of malformations and signs of infection.Calcifications were mainly located in the liver, but also in heart, bowel, and other tissues. Fetuses with calcifications showed a significantly higher proportion of chromosomal abnormalities than controls; 50% vs. 20% (p<0.001. The most frequent aberrations among cases included trisomy 21 (33%, trisomy 18 (22%, and monosomy X (18%. A similar distribution was seen among controls. When comparing cases and controls with chromosomal abnormalities, the cases had a significantly higher prevalence of malformations (95% vs. 77%, p=0.004. Analyzed the other way around, cases with malformations had a significantly higher proportion of chromosomal abnormalities compared with controls, (66% vs. 31%, p<0.001.The presence of fetal calcifications is associated with high risk of chromosomal abnormality in combination with malformations. Identification of a calcification together with a malformation at autopsy more than doubles the probability of detecting a chromosomal abnormality, compared with identification of a malformation only. We propose that identification of a fetal tissue calcification at autopsy, and potentially also at ultrasound examination, should infer

  8. Communication and abnormal behaviour.

    1979-01-01

    In this paper the similarities between normal and abnormal behaviour are emphasized and selected aspects of communication, normal and aberrant, between persons are explored. Communication in a social system may be verbal or non-verbal: one person's actions cause a response in another person. This response may be cognitive, behavioural or physiological. Communication may be approached through the individual, the social situation or social interaction. Psychoanalysis approaches the individual in terms of the coded communications of psychoneurotic symptoms or psychotic behaviour; the humanist-existential approach is concerned more with emotional expression. Both approaches emphasize the development of individual identity. The interaction between persons and their social background is stressed. Relevant are sociological concepts such as illness behaviour, stigma, labelling, institutionalization and compliance. Two approaches to social interactions are considered: the gamesplaying metaphor, e.g. back pain as a psychosocial manipulation--the 'pain game'; and the 'spiral of reciprocal perspectives' which emphasizes the interactional complexities of social perceptions. Communicatory aspects of psychological treatments are noted: learning a particular metaphor such as 'resolution' of the problem (psychotherapy), learning more 'rewarding' behaviour (learning theory) or learning authenticity or self-actualization (humanist-existential).

    Full Text Available Abstract Background Several studies have shown that the pathophysiology of homozygous sickle cell anaemia (SCA results in a myriad of metabolic, nutritional, haematological and clinical effects that interact with other co-morbid factors to determine the quality of life and life expectancy of afflicted patients. Because of its critical roles in nutrition and metabolism, inflammation, haematopoiesis and cellular immunity, this study determined the plasma levels of leptin in steady and unsteady states of HbSS in Nigerian patients. Methods A total of 51 SCA patients aged 5 - 35 years with 34 (61.8% being females who were either on admission or visiting four medical centres in Lagos, Nigeria together with 22 non-SCD controls aged 5 -30 years comprising 12 (54.5% females were enrolled after obtaining their informed consent and ethical approval. Patients were further stratified into steady and unsteady cases of SCA based on clinical presentations, while blood samples collected by venipuncture from each of the study participants were analyzed haematologically for full blood count and HbF level and microscopically for malaria, while plasma leptin was assayed using ELISA method. Body composition defined by weight, fat mass and body mass index (BMI was determined using standard methods. Data obtained for cases and controls were analyzed statistically. Results Twenty - one patients had unsteady HbSS and elicited greater and significant (P P. falciparum parasitaemia (4613.7 vs. 749.6 - 1078.4 parasites/uL, pyrexia rate (58.3 vs. 25.8% when compared with steady state patients or non-SCD controls. Compared to the control, significant decreases in plasma leptin before and after controlling for body fat that was worsened by crisis were observed among the SCD patients. Unlike the non-SCD controls, leptin correlated non-significantly (P > 0.05 with all body composition indices measured in the patients except for fat mass in unsteady cases. Multivariate regression

    Recent imaging studies have associated Developmental dyscalculia (DD) to structural and functional alterations corresponding Parietal and the Prefrontal cortex (PFC). Since these areas were shown also to be involved in timing abilities, we hypothesized that time processing is abnormal in DD. We compared time processing abilities between 10 children with pure DD (8 years old) and 11 age-matched healthy children. Results show that the DD group underestimated duration of a sub-second scale when asked to perform a time comparison task. The timing abnormality observed in our DD participants is consistent with evidence of a shared fronto-parietal neural network for representing time and quantity.

    Anaemia in children living in sub-Saharan Africa is common, but its causes are diverse. In 545 children below 5 years of age from rural southern Rwanda, we assessed the role of iron deficiency (ID) and of the TMPRSS6 736(V) (rs855791) allele, known to reduce iron status and haemoglobin (Hb) levels, in anaemia and Hb concentrations. Anaemia (Hb anaemia (adjusted odds ratio, 1.67) to an extent comparable with α(+) -thalassaemia, breastfeeding, inflammation and low household income, but the odds were substantially higher in Plasmodium falciparum infection (adjusted odds ratio, 10.3). These findings were verified in a multivariate analysis of Hb concentrations. The TMPRSS6 736(V) allele only tended to be associated with low Hb levels. TMPRSS6 736(V) is comparatively rare among Rwandan children and may only slightly contribute to low Hb concentrations. Preventable causes of anaemia, notably ID and P. falciparum infection, largely outweigh its impact and need to be addressed to improve the haematological status of children in the study area.

    Full Text Available Background: Anaemia is estimated to affect half the school-age children and adolescents in developing countries. Aim: This study aimed to determine the prevalence of anaemia and evaluate the relationship of intestinal helminth infection on the anaemia status of children in the rural communities of Evbuomore, Isiohor, and Ekosodin. in the Ovia North East local government area of Edo State, Nigeria. Subjects and Methods: Faecal samples and blood samples were obtained from 316 children aged 1-15 years. Faecal samples were examined using standard parasitological techniques, and anaemia was defined as blood haemoglobin <11 g/dL. Results: Of the 316 children, 38.6% were anaemic: 75.9% of children in Evbuomore, 42.3% in Isiohor and 26.8% in Ekosodin. The overall parasite prevalence in the three communities were: Ascaris lumbricoides (75.6%, hookworm (16.19% and Trichuris trichiura (7.3%. Malnutrition was patent; 37.0% of the children were stunted, 19.3% wasted, and 44.0% underweight. There was a statistically significant association between hookworm and Ascaris lumbricoides infection and anaemia (P < .001. Serum ferritin levels were more sensitive than haemoglobin in detecting anemia and were correlated with intestinal helminth infection. Conclusion: Intestinal helminth infection in a concomitant state of malnutrition is observed in this population. Intervention programmes should be aimed at control of intestinal helminth infection and iron supplementation.

    In a retrospective investigation of the court reports about sexual homicide perpetrators chromosome analysis had been carried out in 13 of 166 (7.8%) men. Three men (1.8%) with XYY chromosome abnormality were found. This rate is much higher than that found in unselected samples of prisoners (0.7-0.9%) or in the general population (0.01%). The three men had shown prepubescent abnormalities, school problems, and had suffered from physical abuse. The chromosome analysis in all cases had been carried out in connection with the forensic psychiatric court report due to the sexual homicide. However, two men had earlier psychiatric referrals. All were diagnosed as sexual sadistic, showed a psychopathic syndrome or psychopathy according to the Psychopathy Checklist-Revised [Hare RD, 1991, The Hare Psychopathy Checklist-Revised, Toronto, Ontario, Canada: Multi-Health Systems]. Two were multiple murderers. Especially forensic psychiatrists should be vigilant of the possibility of XYY chromosome abnormalities in sexual offenders.

    Ferric carboxymaltose (Ferinject(R)), a novel iron complex that consists of a ferric hydroxide core stabilized by a carbohydrate shell, allows for controlled delivery of iron to target tissues. Administered intravenously, it is effective in the treatment of iron-deficiency anaemia, delivering a replenishment dose of up to 1000 mg of iron during a minimum administration time of carboxymaltose rapidly improves haemoglobin levels and replenishes depleted iron stores in various populations of patients with iron-deficiency anaemia, including those with inflammatory bowel disease, heavy uterine bleeding, postpartum iron-deficiency anaemia or chronic kidney disease. It was well tolerated in clinical trials. Ferric carboxymaltose is, therefore, an effective option in the treatment of iron-deficiency anaemia in patients for whom oral iron preparations are ineffective or cannot be administered. Ferric carboxymaltose is a macromolecular ferric hydroxide carbohydrate complex, which allows for controlled delivery of iron within the cells of the reticuloendothelial system and subsequent delivery to the iron-binding proteins ferritin and transferrin, with minimal risk of release of large amounts of ionic iron in the serum. Intravenous administration of ferric carboxymaltose results in transient elevations in serum iron, serum ferritin and transferrin saturation, and, ultimately, in the correction of haemoglobin levels and replenishment of depleted iron stores. The total iron concentration in the serum increased rapidly in a dose-dependent manner after intravenous administration of ferric carboxymaltose. Ferric carboxymaltose is rapidly cleared from the circulation and is distributed primarily to the bone marrow ( approximately 80%) and also to the liver and spleen. Repeated weekly administration of ferric carboxymaltose does not result in accumulation of transferrin iron in patients with iron-deficiency anaemia. Intravenously administered ferric carboxymaltose was effective in

    Systemic abnormalities often occur in patients with liver disease. In particular, cardiopulmonary or renal diseases accompanied by advanced liver disease can be serious and may determine the quality of life and prognosis of patients. Therefore, both hepatologists and non-hepatologists should pay attention to such abnormalities in the management of patients with liver diseases.

  19. Abnormal pressure in hydrocarbon environments

    Law, B.E.; Spencer, C.W.

    1998-01-01

    Abnormal pressures, pressures above or below hydrostatic pressures, occur on all continents in a wide range of geological conditions. According to a survey of published literature on abnormal pressures, compaction disequilibrium and hydrocarbon generation are the two most commonly cited causes of abnormally high pressure in petroleum provinces. In young (Tertiary) deltaic sequences, compaction disequilibrium is the dominant cause of abnormal pressure. In older (pre-Tertiary) lithified rocks, hydrocarbon generation, aquathermal expansion, and tectonics are most often cited as the causes of abnormal pressure. The association of abnormal pressures with hydrocarbon accumulations is statistically significant. Within abnormally pressured reservoirs, empirical evidence indicates that the bulk of economically recoverable oil and gas occurs in reservoirs with pressure gradients less than 0.75 psi/ft (17.4 kPa/m) and there is very little production potential from reservoirs that exceed 0.85 psi/ft (19.6 kPa/m). Abnormally pressured rocks are also commonly associated with unconventional gas accumulations where the pressuring phase is gas of either a thermal or microbial origin. In underpressured, thermally mature rocks, the affected reservoirs have most often experienced a significant cooling history and probably evolved from an originally overpressured system.

    Infectious salmon anaemia (ISA) is a highly fatal viral disease affecting marine-farmed Atlantic salmon which is caused by ISA virus (ISAV), a fish orthomyxovirus that has recently been assigned to the new genus Isavirus within the family Orthomyxoviridae. Mx proteins are among the interferon (IFN)-induced proteins responsible for the development of an antiviral state in vertebrate cells. We used real-time reverse transcription-polymerase chain reaction (RT-PCR) and Chinook salmon embryo (CHSE-214) cells constitutively expressing Atlantic salmon Mx1 protein (ASMx1) to examine the antiviral properties of ASMx1 against two ISAV strains, NBISA01 and HKS-36, having phenotypically different growth properties (cytopathic vs non-cytopathic) in the CHSE-214 cell line. We present evidence that ISAV is sensitive to ASMx1. CHSE-214 cells constitutively expressing ASMx1 showed increased resistance to infection with the cytopathic ISAV strain NBISA01, manifested as delayed development of cytopathic effects (CPE) and significant reduction in the severity of CPE, as well as a 10-fold reduction in virus yield. However, by real-time RT-PCR we observed no significant difference in the mean threshold cycle (Ct) values of ISAV RNA levels, suggesting that the ASMx1 activity on ISAV occurs at the post-transcription steps of virus replication, possibly in the cytoplasm.

    Since 1975 the Rome Microcythaemia Centre has carried out every year, under the auspices of the health authorities of the Latium region, a screening of thalassaemics among intermediate schoolchildren of Latium. From these campaigns, knowledge about thalassaemias among the young adult population has grown which, in its turn, has resulted in screening of these young adults. Through screening in schools between 1975 and 1982, of 289 763 students examined, 6838 thalassaemics were identified, 6045 of whom were beta- or delta beta-thalassaemics. The total number of young thalassaemics who are identified at present in the Centre through screenings of schoolchildren and young adults is about 3300 per year. Furthermore, from January 1980 to April 1983, 110 prospective couples of child-bearing age at risk (94 of whom originated from Latium) were identified at the Centre, and five homozygous fetuses (three of which originated from Latium) were diagnosed. These data derive from an area in which the frequency of thalassaemia is only 2.4%, and they show that the programme in Latium for the prevention of Mediterranean anaemia has been successful.

    Allogeneic haematopoietic stem cell transplantation (HSCT) is the only curative option for patients with Diamond Blackfan anaemia (DBA). We report the transplantation outcome of 30 Italian DBA patients referred to the Italian Association of Paediatric Haematology and Oncology Registry between 1990 and 2012. This is one of the largest national registry cohorts of transplanted DBA patients. Most patients (83%) were allografted after 2000. A matched sibling donor was employed in 16 patients (53%), the remaining 14 patients (47%) were transplanted from matched unrelated donors. Twenty-eight of the 30 patients engrafted. One patient died at day +6 due to veno-occlusive disease without achieving neutrophil recovery and another patient remained transfusion-dependent despite the presence of a full donor chimerism. The 5-year overall survival and transplant-related mortality was 74·4% and 25·6%, respectively. Patients younger than 10 years as well as those transplanted after 2000 showed a significantly higher overall survival and a significantly lower risk of transplant-related mortality. No difference between donor type was observed. Our data suggest that allogeneic HSCT from a related or unrelated donor was a reasonable alternative to transfusion therapy in young and well chelated DBA patients.

    Full Text Available BACKGROUND: Childhood anaemia is considered a severe public health problem in most countries of sub-Saharan Africa. We investigated the geographical distribution of prevalence of anaemia and mean haemoglobin concentration (Hb in children aged 1-4 y (preschool children in West Africa. The aim was to estimate the geographical risk profile of anaemia accounting for malnutrition, malaria, and helminth infections, the risk of anaemia attributable to these factors, and the number of anaemia cases in preschool children for 2011. METHODS AND FINDINGS: National cross-sectional household-based demographic health surveys were conducted in 7,147 children aged 1-4 y in Burkina Faso, Ghana, and Mali in 2003-2006. Bayesian geostatistical models were developed to predict the geographical distribution of mean Hb and anaemia risk, adjusting for the nutritional status of preschool children, the location of their residence, predicted Plasmodium falciparum parasite rate in the 2- to 10-y age group (Pf PR(2-10, and predicted prevalence of Schistosoma haematobium and hookworm infections. In the four countries, prevalence of mild, moderate, and severe anaemia was 21%, 66%, and 13% in Burkina Faso; 28%, 65%, and 7% in Ghana, and 26%, 62%, and 12% in Mali. The mean Hb was lowest in Burkina Faso (89 g/l, in males (93 g/l, and for children 1-2 y (88 g/l. In West Africa, severe malnutrition, Pf PR(2-10, and biological synergisms between S. haematobium and hookworm infections were significantly associated with anaemia risk; an estimated 36.8%, 14.9%, 3.7%, 4.2%, and 0.9% of anaemia cases could be averted by treating malnutrition, malaria, S. haematobium infections, hookworm infections, and S. haematobium/hookworm coinfections, respectively. A large spatial cluster of low mean Hb (95% was predicted for an area shared by Burkina Faso and Mali. We estimate that in 2011, approximately 6.7 million children aged 1-4 y are anaemic in the three study countries. CONCLUSIONS: By

    Recently, the Kidney Disease: Improving Global Outcomes (KDIGO) group has produced comprehensive clinical practice guidelines for the management of anaemia in CKD patients. These guidelines addressed all of the important points related to anaemia management in CKD patients, including therapy with erythropoieis stimulating agents (ESA), iron therapy, ESA resistance and blood transfusion use. Because most guidelines were 'soft' rather than 'strong', and because global guidelines need to be adapted and implemented into the regional context where they are used, on behalf of the European Renal Best Practice Advisory Board some of its members, and other external experts in this field, who were not participants in the KDIGO guidelines group, were invited to participate in this anaemia working group to examine and comment on the KDIGO documents in this position paper. In this article, the group concentrated only on those guidelines which we considered worth amending or adapting. All guidelines not specifically mentioned are fully endorsed.

    Fanconi anaemia (FA) is an inherited condition characterised by congenital and developmental abnormalities and a strong cancer predisposition. In around 3-5% of cases FA is caused by biallelic mutations in the BRCA2 gene. Individuals heterozygous for BRCA2 mutations have an increased risk of inherited breast and ovarian cancer. We reviewed the mutation spectrum in BRCA2-associated FA, and the spectrum and frequency of BRCA2 mutations in distinct populations. The rarity of FA due to biallelic BRCA2 mutations supports a fundamental role of BRCA2 for prevention of malignant transformation during development. The spectrum of malignancies seen associated with FA support the concept of a tissue selectivity of BRCA2 mutations for development of FA-associated cancers. This specificity is illustrated by the distinct FA-associated BRCA2 mutations that appear to predispose to specific brain or haematological malignancies. For some populations, the number of FA-patients with biallelic BRCA2 disruption is smaller than that expected from the carrier frequency, and this implies that some pregnancies with biallelic BRCA2 mutations do not go to term. The apparent discrepancy between expected and observed incidence of BRCA2 mutation-associated FA in high-frequency carrier populations has important implications for the genetic counselling of couples with recurrent miscarriages from high-risk populations.

  9. Increased microerythrocyte count in homozygous alpha(+-thalassaemia contributes to protection against severe malarial anaemia.

    Full Text Available BACKGROUND: The heritable haemoglobinopathy alpha(+-thalassaemia is caused by the reduced synthesis of alpha-globin chains that form part of normal adult haemoglobin (Hb. Individuals homozygous for alpha(+-thalassaemia have microcytosis and an increased erythrocyte count. Alpha(+-thalassaemia homozygosity confers considerable protection against severe malaria, including severe malarial anaemia (SMA (Hb concentration 1.1 x 10(12/l as a result of the reduced mean cell Hb in homozygous alpha(+-thalassaemia. In addition, children homozygous for alpha(+-thalassaemia require a 10% greater reduction in erythrocyte count than children of normal genotype (p = 0.02 for Hb concentration to fall to 50 g/l, the cutoff for SMA. We estimated that the haematological profile in children homozygous for alpha(+-thalassaemia reduces the risk of SMA during acute malaria compared to children of normal genotype (relative risk 0.52; 95% confidence interval [CI] 0.24-1.12, p = 0.09. CONCLUSIONS: The increased erythrocyte count and microcytosis in children homozygous for alpha(+-thalassaemia may contribute substantially to their protection against SMA. A lower concentration of Hb per erythrocyte and a larger population of erythrocytes may be a biologically advantageous strategy against the significant reduction in erythrocyte count that occurs during acute infection with the malaria parasite Plasmodium falciparum. This haematological profile may reduce the risk of anaemia by other Plasmodium species, as well as other causes of anaemia. Other host polymorphisms that induce an increased erythrocyte count and microcytosis may confer a similar advantage.

    Full Text Available The escalating burden, pathogenesis, and clinical sequel of malaria during pregnancy have combinatorial adverse impact on both mother and foetus that further perplexed the situation of diagnosis, treatment, and prevention. This prompted us to evaluate the status of population at risk of MIP in Hazaribag, Jharkhand, India. Cross-sectional study was conducted over a year at Sadar Hospital, Hazaribag. Malaria was screened using blood smear and/or RDT. Anaemia was defined as haemoglobin concentration. Pretested questionnaires were used to gather sociodemographic, clinical, and obstetrical data. The prevalence of MIP was 5.4% and 4.3% at ANC and DU, and 13.2% malaria was in women without pregnancy. Interestingly, majority were asymptomatically infected with P. vivax (over 85% at ANC and DU. Peripheral parasitemia was significantly associated with fever within past week, rural origin of subjects, and first/second pregnancies in multivariate analysis, with the highest risk factor associated with fever followed by rural residence. Strikingly in cohort, anaemia was prevalent in 86% at ANC as compared to 72% at DU, whereas severe anaemia was 13.6% and 7.8% at ANC and DU. Even more anaemia prevalence was observed in MIP group (88% and 89% at ANC and DU, whereas severe anaemia was 23% and 21%, respectively. In view of observed impact of anaemia, parasitemia and asymptomatic infection of P. vivax during pregnancy and delivery suggest prompt diagnosis regardless of symptoms and comprehensive drug regime should be offered to pregnant women in association with existing measures in clinical spectrum of MIP, delivery, and its outcome.

    Primary Antiphospholipid Antibody Syndrome (PAPS) and Autoimmune haemolytic anemia (AIHA) is a very rare combination. Antiphospholipid Antibody Syndrome (APS) with underlying SLE, however, has a well documented association with Coomb's positive Auoimmune Haemolytic Anaemia. We describe a young girl with PAPS presenting with deep venous thrombosis, livedo reticularis and features of AIHA. The patient was refractory to treatment for 5 years however, her condition improved dramatically with anticoagulants, corticosteroid therapy and the addition of hydroxychloroquine and azathioprin. We have also discussed hydroxychloroquine therapy in PAPS which is not yet fully established and the probability of this patient developing other autoimmune disorders in future.

    How the Fanconi anaemia (FA) chromosome stability pathway functions to cope with interstrand crosslinks and other DNA lesions has been elusive, even after FANCD1 proved to be BRCA2, a partner of Rad51 in homologous recombination. The identification and characterization of two new Fanconi proteins having helicase motifs, FANCM and FANCJ/BRIP1/BACH1, implicates the FANC nuclear core complex as a participant in recognizing or processing damaged DNA, and the BRIP1 helicase as acting independently of this complex.

    Full Text Available Background & objectives: Iron deficiency anaemia (IDA is the most common nutritional deficiency in pregnancy. Prophylactic oral iron is recommended during pregnancy to meet the increased requirement. In India, women become pregnant with low baseline haemoglobin level resulting in high incidence of moderate to severe anaemia in pregnancy where oral iron therapy cannot meet the requirement. Pregnant women with moderate anaemia are to be treated with parentral iron therapy. This study was undertaken to evaluate the response and effect of intravenous iron sucrose complex (ISC given to pregnant women with IDA. Methods: A prospective study was conducted (June 2009 to June 2011 in the department of Obstetrics & Gynecology, All India Institute of Medical Sciences, New Delhi. One hundred pregnant women with haemoglobin between 5-9 g% with diagnosed iron deficiency attending antenatal clinic were given intravenous iron sucrose complex in a dose of 200 mg twice weekly schedule after calculating the dose requirement. Results: The mean haemoglobin raised from 7.63 ± 0.61 to 11.20 ± 0.73 g% (P<0.001 after eight wk of therapy. There was significant rise in serum ferritin levels (from 11.2 ± 4.7 to 69 ± 23.1 μg/l (P<0.001. Reticulocyte count increased significantly after two wk of starting therapy (from 1.5 ± 0.6 to 4.6±0.8%.Other parameters including serum iron levels and red cell indices were also improved significantly. Only one woman was lost to follow up. No major side effects or anaphylactic reactions were noted during study period. Interpretation & conclusions: Parentral iron therapy was effective in increasing haemoglobin, serum ferritin and other haematological parameters in pregnant women with moderate anaemia. Intravenous iron sucrose can be used in hospital settings and tertiary urban hospitals where it can replace intramuscular therapy due to injection related side effects. Further, long-term comparative studies are required to recommend its

    Parasitic infections continue to take their toll on HIV positive patients by influencing the blood qualitatively and quantitatively. The objective of this study was to determine the prevalence of intestinal parasitic infections in relation to anaemia and CD4 counts among HIV-infected patients in Benin City, Nigeria. Using a serial sampling method, a total of 2000 HIV-infected patients were recruited on their first visit prior to highly active anti-retroviral therapy (HAART) at the University of Benin Teaching Hospital from August 2007 to August 2009. Stool and blood samples were collected from each patient. The stool samples were processed using the modified Ziehl-Neelsen staining technique to microscopically identify the oocysts of Cryptosporidium species, Isospora belli, Cyclospora species and spores of Microsporidium species while saline and iodine preparations were used for identifying the ova, cysts and parasites of Ascaris lumbricoides, hookworm, Taenia spp and other parasites. The blood specimens were equally analyzed using the flow cytometry for CD4+ T-lymphocyte count and autoanalyzer - sysmex kx - 21 for haemoglobin concentration. The overall prevalence of anaemia was 93.3% while 18% had parasitic infections. There was a significant relationship between CD4 count <200cells/microL and anaemia (P<0.0001). Cryptosporidium species (P= 0.005), A. lumbricoides (P=0.035), hookworm and Taenia species (P=0.014) were associated with anaemia. Anaemia was associated with CD4 count while Cryptosporidium species, Ascaris lumbricoides, hookworm and Taenia species were the intestinal parasitic agents associated with anaemia. In conclusion the prevalence of anaemia in HIV-infected patients is high low CD4 count is a significant risk factor of acquiring anaemia. Except for isosporiasis, cryptosporidiosis, A. lumbricoides, hookworm and Taenia species in HIV infected individuals are parasitic agents associated with anaemia. Routine screening for intestinal parasites and

    Full Text Available Little evidence about the effects of antenatal iron supplementation on infant anaemia is available. The aim was to compare effects on six-month-old infants' Haemoglobin (Hb concentration and anaemia of daily iron-folic acid (IFA, twice-weekly IFA with or without other micronutrients (MMN and usual antenatal care in rural Vietnam.Secondary data analysis from: a prospective population-based observational study (OS which examined effects of antenatal psychosocial factors, anaemia and iron deficiency on infant development and health; and a three-arm cluster randomised trial (CRT of different antenatal iron supplementation regimens. In the OS 497 women (<20 weeks gestation from 50 randomly-selected communes participated, and in the CRT 1,258 pregnant women (<16 weeks gestation in 104 communes were allocated randomly to trial arms. The main outcome was six-month-old infant Hb concentration. Baseline data included women's socio-demographic characteristics, reproductive health, Hb and serum ferritin. Mean differences in infant Hb and odds ratios of infant anaemia between CRT arms and OS were calculated by multivariable regression models, controlling for baseline differences and clustering, using robust standard errors. Infant anaemia prevalence was 68.6% in the OS, 47.2% daily IFA, 53.5% weekly IFA, and 50.3% MMN conditions. After adjustment, mean infant haemoglobin levels in daily IFA (mean difference = 0.95 g/dL; 95%CI 0.7-11.18; weekly IFA (0.91; 95%CI 0.69-1.12 and MMN (1.04; 95%CI 0.8-1.27 were higher than in the OS. After adjustment there were lower odds ratios of anaemia among infants in the daily IFA (OR = 0.31; 95% CI 0.22-0.43, weekly IFA (0.38; 95%CI 0.26-0.54 and MMN (0.33; 95%CI 0.23-0.48 groups than in the OS.Infant anaemia is a public health problem in Vietnam and other resource-constrained countries. All supplementation regimens could have clinically significant benefits for Hb and reduce anaemia risk among six-month-old infants

  19. Parsing abnormal grain growth in specialty aluminas

    Science.gov (United States)

    Lawrence, Abigail Kremer

    multivariate statistical tool called canonical correlation analysis was adopted to seek out relationships between a set of input variables and the abnormal character values. The input variables include the MgO, CaO, Na 2O, and SiO2 contents, the ratio of MgO:(CaO+SiO2), and the annealing time and temperature. The analysis was applied to 33 different samples and showed that the composition ratio and MgO content were the strongest processing variables. These variables are most closely related to the correlation between grain size and aspect ratio, the average magnitude of abnormality, and the variance in grain size. The physical implications of these relationships are explored for a number of samples with different abnormal grain growth behaviors. Several of the samples contained a beta"-alumina phase that is shown to have a dampening effect on abnormal grain growth. TEM investigation provides evidence that there is a grain boundary complexion with a different composition and structure than the second phase. A series of samples are compared after annealing for different times and are shown to have very different behaviors as a result of the second phase competing with complexions for control over the microstructure.

    Full Text Available Abstract Background Infectious salmon anaemia (ISA virus (ISAV, which causes ISA in marine-farmed Atlantic salmon, is an orthomyxovirus belonging to the genus Isavirus, family Orthomyxoviridae. ISAV agglutinates erythrocytes of several fish species and it is generally accepted that the ISAV receptor destroying enzyme dissolves this haemagglutination except for Atlantic salmon erythrocytes. Recent work indicates that ISAV isolates that are able to elute from Atlantic salmon erythrocytes cause low mortality in challenge experiments using Atlantic salmon. Previous work on ISAV-induced haemagglutination using the highly pathogenic ISAV strain NBISA01 and the low pathogenic ISAV strain RPC/NB-04-0851, showed endocytosis of NBISA01 but not RPC/NB-04-0851. Real-time RT-PCR was used to assess the viral RNA levels in the ISAV-induced haemagglutination reaction samples, and we observed a slight increase in viral RNA transcripts by 36 hours in the haemagglutination reaction with NBISA01 virus when the experiment was terminated. However, a longer sampling interval was considered necessary to confirm ISAV replication in fish erythrocytes and to determine if the infected cells mounted any innate immune response. This study examined the possible ISAV replication and Type I interferon (IFN system gene induction in Atlantic salmon erythrocytes following ISAV haemagglutination. Results Haemagglutination assays were performed using Atlantic salmon erythrocytes and one haemagglutination unit of the two ISAV strains, NBISA01 and RPC/NB-04-0851, of differing genotypes and pathogenicities. Haemagglutination induced by the highly pathogenic NBISA01 but not the low pathogenic RPC/NB-04-0851 resulted in productive infection as evidenced by increased ISAV segment 8 transcripts and increase in the median tissue culture infectious dose (TCID50 by 5 days of incubation. Moreover, reverse transcription (RT quantitative PCR used to compare mRNA levels of key Type I IFN system

    2015-01-01

    Despite decades of widespread use, the adverse effect profile of "selective" serotonin reuptake inhibitor (SSRI) antidepressants has still not been fully elucidated. Studies in male animals have shown delayed sexual development and reduced fertility. Three prospective cohort studies conducted in over one hundred patients exposed to an SSRI for periods ranging from 5 weeks to 24 months found altered semen param-eters after as little as 3 months of exposure: reduced sperm concentration, reduced sperm motility, a higher percentage of abnormal spermatozoa, and increased levels of sperm DNA fragmentation. One clinical trial showed growth retardation in children considered depressed who were exposed to SSRls. SSRls may have endocrine disrupting properties. Dapoxetine is a short-acting serotonin reuptake inhibitor that is chemically related to fluoxetine and marketed in the European Union for men complaining of premature ejaculation. But the corresponding European summary of product characteristics does not mention any effects on fertility. In practice, based on the data available as of mid-2014, the effects of SSRI exposure on male fertility are unclear. However, it is a risk that should be taken into account and pointed out to male patients who would like to father a child or who are experiencing fertility problems.

  5. [Y chromosome structural abnormalities and Turner's syndrome].

    Although specifically male, the human Y chromosome may be observed in female karyotypes, mostly in women with Turner syndrome stigmata. In women with isolated gonadal dysgenesis but otherwise normal stature, the testis determining factor or SRY gene may have been removed from the Y chromosome or may be mutated. In other women with Turner syndrome, the karyotype is usually abnormal and shows a frequent 45,X/46,XY mosaicism. In these cases, the phenotype depends on the ratio between Y positive and 45,X cell lines in the body. When in mosaicism, Y chromosomes are likely to carry structural abnormalities which explain mitotic instability, such as the existence of two centromeres. Dicentric Y isochromosomes for the short arm (idic[Yp]) or ring Y chromosomes (r[Y]) are the most frequent abnormal Y chromosomes found in infertile patients and in Turner syndrome in mosaic with 45,X cells. Although monocentric, deleted Y chromosomes for the long arm and those carrying microdeletions in the AZF region are also instable and are frequently associated with a 45,X cell line. Management of infertile patients carrying such abnormal Y chromosomes must take into account the risk and the consequences of a mosaicism in the offspring.

    Background. Sickle cell disorders are known to have a negative effect on linear growth. This could potentially affect proportional growth and, hence, Cormic Index. Objective. To determine the Cormic Index in the sickle cell anaemia population in Lagos. Methodology. A consecutive sample of 100 children with haemoglobin genotype SS, aged eight months to 15 years, and 100 age and sex matched controls (haemoglobin genotype AA) was studied. Sitting height (upper segment) and full length or height were measured. Sitting height was then expressed as a percentage of full length/height (Cormic Index). Results. The mean Cormic Index decreased with age among primary subjects (SS) and AA controls. The overall mean Cormic Index among primary subjects was comparable to that of controls (55.0 ± 4.6% versus 54.5 ± 5.2%; 54.8 ± 4.5% versus 53.6 ± 4.9%) in boys and girls, respectively. In comparison with AA controls, female children with sickle cell anaemia who were older than 10 years had a significantly lower mean Cormic Index. Conclusion. There was a significant negative relationship between Cormic Index and height in subjects and controls irrespective of gender. Similarly, a significant negative correlation existed between age, sitting height, subischial leg length, weight, and Cormic Index in both subjects and controls.

To investigate the incidence of infectious morbidity in infants in rural Malawi in relation to birth weight and fetal anaemia, a cohort of babies was followed for a year on the basis of LBW (<2500) and FA (cord haemoglobin < 12.5 g/dl). A matched group of normal birth weight (NBW), non-anaemic (NFA) new-borns were enrolled as controls. Morbidity episodes were recorded at 4-weekly intervals and at each extra visit made to a health centre with any illness. Infants in the NBW NFA group experienced an average of 1.15 (95% C.I. 0.99, 1.31), 1.04 (0.89, 1.19), 0.92 (0.73, 1.11) episodes per year of malaria, respiratory infection and diarrhoea respectively. Corresponding values for the LBW FA group were 0.83 (0.5, 1.16), 0.82 (0.5, 1.16) and 0.76 (0.33, 1.19). FA was not associated with a higher incidence of morbidity, but was significantly associated with a shorter time to first illness episode (p = 0.014). LBW was not a significant risk factor for higher morbidity incidence. LBW and FA were not significant risk factors for incidence of illness episodes in infants.

    Full Text Available Abstract Background The main hypothesis of this study is that Oxpentifylline administration will effectively treat erythropoietin- or darbepoietin-resistant anaemia in chronic kidney disease patients. Methods/design Inclusion criteria are adult patients with stage 4 or 5 chronic kidney disease (including dialysis patients with significant anaemia (haemoglobin ≤ 110 g/L for at least 3 months for which there is no clear identifiable cause and that is unresponsive to large doses of either erythropoietin (≥ 200 IU/kg/week or darbepoetin (≥ 1 μg/kg/week. Patients will be randomized 1:1 to receive either placebo (1 tablet daily or oxpentifylline (400 mg daily per os for a period of 4 months. During this 4 month study period, haemoglobin measurements will be performed monthly. The primary outcome measure will be the difference in haemoglobin level between the 2 groups at the end of the 4 month study period, adjusted for baseline values. Secondary outcome measures will include erythropoiesis stimulating agent dosage, Key's index (erythropoiesis stimulating agent dosage divided by haemoglobin concentration, and blood transfusion requirement. Discussion This investigator-initiated multicentre study has been designed to provide evidence to help nephrologists and their chronic kidney disease patients determine whether oxpentifylline represents a safe and effective strategy for treating erythropoiesis stimulating agent resistance in chronic kidney disease.

    A theory of composite material patch winding is proposed to determine the winding trajectory with a meshed data model. Two different conditions are considered in this study. One is Bridge condition on the concave surface and the other is Slip line condition in the process of patch winding. This paper presents the judgment principles and corresponding solutions by applying differential geometry theory and space geometry theory. To verify the feasibility of the patch winding method, the winding control code is programmed. Furthermore, the winding experiments on an airplane inlet and a vane are performed. From the experiments, it shows that the patch winding theory has the advantages of flexibility, easy design and application.

    AIM: Biological medicine is hard to fully and scientifically explain the etiological factor and pathogenesis of abnormal behaviors; while, researches on philosophy and psychology (including memetics) are beneficial to better understand and explain etiological factor and pathogenesis of abnormal behaviors. At present, the theory of philosophy and psychology is to investigate the entity of abnormal behavior based on the views of memetics.METHODS: Abnormal behavior was researched in this study based on three aspects, including instinctive behavior disorder, poorly social-adapted behavior disorder and mental or body disease associated behavior disorder. Most main viewpoints of memetics were derived from "The Meme Machine", which was written by Susan Blackmore. When questions about abnormal behaviors induced by mental and psychological diseases and conduct disorder of teenagers were discussed, some researching achievements which were summarized by authors previously were added in this study, such as aggressive behaviors, pathologically aggressive behaviors, etc.RESULTS: The abnormal behaviors mainly referred to a part of people's substandard behaviors which were not according with the realistic social environment, culture background and the pathologic behaviors resulted from people's various psychological diseases. According to the theory of "meme", it demonstrated that the relevant behavioral obstacles of various psychological diseases, for example, the unusual behavior of schizophrenia, were caused, because the old meme was destroyed thoroughly but the new meme was unable to establish; psychoneurosis and personality disorder were resulted in hard establishment of meme; the behavioral obstacles which were ill-adapted to society, for example, various additional and homosexual behaviors, were because of the selfish replications and imitations of "additional meme" and "homosexual meme"; various instinct behavioral and congenital intelligent obstacles were not significance

    We prospectively studied 45 anaemic patients (37 women, 8 men) with chronic inflammatory rheumatic diseases. The combination of serum ferritin and CRP (as well as ESR) in its predictive capacity for bone marrow iron stores was examined. The relationship between other iron-related measurements (transferrin, transferrin saturation, soluble transferrin receptor, erythrocyte porphyrins and percentage of hypochromic/microcytic erythrocytes) and bone marrow iron stores was also investigated. Stainable bone marrow iron was taken as the most suitable standard to separate iron-deficient from iron-replete patients. 14 patients (31%) were lacking bone marrow iron. Regression analysis showed a good correlation between ferritin and bone marrow iron (adjusted R2 = 0.721, P power for bone marrow iron (adjusted R2 = 0.715) in this cohort of patients with low systemic inflammatory activity. With respect to the bone marrow iron content the best predictive cut-off value of ferritin was 30 micrograms/l (86% sensitivity, 90% specificity). The other iron-related parameters both individually and when combined were less powerful in predicting bone marrow iron than ferritin alone. Only zinc bound erythrocyte protoporphyrin in combination with ferritin slightly improved prediction (adjusted R2 = 0.731). A cut-off point of 11% hypochromic erythrocytes reached a high specificity (90%), but was less sensitive (77%).

    Full Text Available Abstract Background Infectious salmon anaemia (ISA virus (ISAV, an important pathogen of fish that causes disease accompanied by high mortality in marine-farmed Atlantic salmon, is the only species in the genus Isavirus, one of the five genera of the Orthomyxoviridae family. The Isavirus genome consists of eight single-stranded RNA species, and the virions have two surface glycoproteins; haemagglutinin-esterase (HE protein encoded on segment 6 and fusion (F protein encoded on segment 5. Based on the initial demonstration of two 5'-coterminal mRNA transcripts by RT-PCR, ISAV genomic segment 7 was suggested to share a similar coding strategy with segment 7 of influenza A virus, encoding two proteins. However, there appears to be confusion as to the protein sizes predicted from the two open reading frames (ORFs of ISAV segment 7 which has in turn led to confusion of the predicted protein functions. The primary goal of the present work was to clone and express these two ORFs in order to assess whether the predicted protein sizes match those of the expressed proteins so as to clarify the coding assignments, and thereby identify any additional structural proteins of ISAV. Results In the present study we show that ISAV segment 7 encodes 3 proteins with estimated molecular masses of 32, 18, and 9.5 kDa. The 18-kDa and 9.5-kDa products are based on removal of an intron each from the primary transcript (7-ORF1 so that the translation continues in the +2 and +3 reading frames, respectively. The segment 7-ORF1/3 product is variably truncated in the sequence of ISAV isolates of the European genotype. All three proteins are recognized by rabbit antiserum against the 32-kDa product of the primary transcript, as they all share the N-terminal 22 amino acids. This antiserum detected a single 35-kDa protein in Western blots of purified virus, and immunoprecipitated a 32-kDa protein in ISAV-infected TO cells.

    Full Text Available Background: AUB is a common but complicated clinical presentation and occurs in 15-20% of women between menarche to menopause and significantly affects the women's health. Women with thyroid dysfunction often have menstrual irregularities, infertility and increased morbidity during pregnancy. The objective of present study is to find the correlation between thyroid disorders and AUB in perimenopausal women attending gynecology OPD. Methods: In the present study, fifty five patients with AUB were included and were evaluated for the cause including thyroid abnormality. Thyroid function tests were done in all patients. Results: Among 55 patients, 12 patients were diagnosed as hypothyroidism and 7 as hyperthyroidism, women with AUB 36 (65.4% were euthyroid. Among 19 women with thyroid abnormality, heavy menstrual bleeding was seen in 8 (42% women, 6 (31.57% had polymenorrhagia, 5 (26.31% had oligomenorrhoea. The frequent menstrual abnormality in women with hypothyroidism (12 women was heavy menstrual bleeding in 5 (41.6% women, 3 (25% had oligomennorhoea, 4 (33.3% had polymenorrhagia. Out of 7 women with hyperthyroidism, 2 (28.57% had oligomenorrhoea, 3 (42.8% had heavy menstrual bleeding, 2 (28.57% had polymenorrhagia. In a total of 55 patients with AUB, 11 (20% had structural abnormalities in uterus and ovaries. 5 (9% had adenomyosis, 3 (5.4% had ovarian cysts, 3 (5.4% had fibroids. Conclusions: It is important to screen all women for thyroid abnormality who are presenting with AUB especially with non-structural causes of AUB. Correction of thyroid abnormalities also relieves AUB. This will avoid unnecessary hormonal treatment and surgery. [Int J Res Med Sci 2015; 3(11.000: 3250-3253

    Full Text Available Abstract Intravenous (i.v. artesunate is now the recommended first-line treatment of severe falciparum malaria in adults and children by WHO guidelines. Nevertheless, several cases of haemolytic anaemia due to i.v. artesunate treatment have been reported. This paper describes the case of an HIV-infected patient with severe falciparum malaria who was diagnosed with haemolytic anaemia after treatment with oral artemether-lumefantrine. The patient presented with fever, headache, and arthromyalgia after returning from Central African Republic where he had been working. The blood examination revealed acute renal failure, thrombocytopaenia and hypoxia. Blood for malaria parasites indicated hyperparasitaemia (6% and Plasmodium falciparum infection was confirmed by nested-PCR. Severe malaria according to the laboratory WHO criteria was diagnosed. A treatment with quinine and doxycycline for the first 12 hours was initially administered, followed by arthemeter/lumefantrine (Riamet® for a further three days. At day 10, a diagnosis of severe haemolytic anaemia was made (Hb 6.9 g/dl, LDH 2071 U/l. Hereditary and autoimmune disorders and other infections were excluded through bone marrow aspiration, total body TC scan and a wide panel of molecular and serologic assays. The patient was treated by transfusion of six units of packed blood red cell. He was discharged after complete remission at day 25. At present, the patient is in a good clinical condition and there is no evidence of haemolytic anaemia recurrence. This is the first report of haemolytic anaemia probably associated with oral artemether/lumefantrine. Further research is warranted to better define the adverse events occurring during combination therapy with artemisinin derivatives.

    To reduce malnutrition and improve child survival, school feeding programmes have been established in many parts of Africa, although prevalence of child malnutrition and anaemia remains high, especially in urban slums. The objective of this study is to evaluate the effect of a school feeding programme in the slums of Nairobi (Kenya) on anaemia and nutritional status, together with an investigation for socioeconomic determinants that may overrule this effect. Sixty-seven children at the St. George primary school in Kibera participated in the school feeding programme for 1 year and data concerning anaemia rate, nutritional status and socioeconomic status were collected during a medical health check. Data were compared with a control group of children attending the same school, of the same age and with the same gender distribution without participation in a feeding programme. Data were analyzed with statistical software (SPSS 17.0). Children participating in the school feeding programme were less stunted (p = 0.02) and wasted (p = 0.02) than children in the control group, and levels of anaemia were lower (p = 0.01). Having no father (p = 0.01) and living in small families (p = 0.003) overruled the effect of the feeding programme. Also, the higher the mother's education, the more wasting was seen (p = 0.04) despite participation in the programme. The programme reduced anaemia and malnutrition and has improved child growth in our study group greatly, but we found that education level of the mother, family size and absence of a father overruled the effect of the school feeding programme. Because sample size of our study is small, we encourage further large-scaled research on reviewing programmatic interventions to develop optimal feeding strategies and improve nutritional status of children.

    Full Text Available Abstract Background Anaemia is an important problem amongst young children living in rural India. However, there has not previously been a detailed study of the biological aetiology of this anaemia, exploring the relative contributions of iron, vitamin B12, folate and Vitamin A deficiency, inflammation, genetic haemoglobinopathy, hookworm and malaria. Nor have studies related these aetiologic biological factors to household food security, standard of living and child feeding practices. Barriers to conducting such work have included perceived reluctance of village communities to permit their children to undergo venipuncture, and logistical issues. We have successfully completed a community based, cross sectional field study exploring in detail the causes of anaemia amongst young children in a rural setting. Methods and design A cross sectional, community based study. We engaged in extensive community consultation and tailored our study design to the outcomes of these discussions. We utilised local women as field workers, harnessing the capacity of local health workers to assist with the study. We adopted a programmatic approach with a census rather than random sampling strategy in the village, incorporating appropriate case management for children identified to have anaemia. We developed a questionnaire based on existing standard measurement tools for standard of living, food security and nutrition. Specimen processing was conducted at the Primary Health Centre laboratory prior to transport to an urban research laboratory. Discussion Adopting this study design, we have recruited 415 of 470 potentially eligible children who were living in the selected villages. We achieved support from the community and cooperation of local health workers. Our results will improve the understanding into anaemia amongst young children in rural India. However, many further studies are required to understand the health problems of the population of rural India, and

    Walking is a spontaneous movement termed locomotion that is promoted by activation of antigravity muscles by serotonergic (5HT) neurons. Development of antigravity activity follows 3 developmental epochs of the sleep-wake (S-W) cycle and is modulated by particular 5HT neurons in each epoch. Activation of antigravity activities occurs in the first epoch (around the age of 3 to 4 months) as restriction of atonia in rapid eye movement (REM) stage and development of circadian S-W cycle. These activities strengthen in the second epoch, with modulation of day-time sleep and induction of crawling around the age of 8 months and induction of walking by 1 year. Around the age of 1 year 6 months, absence of guarded walking and interlimb cordination is observed along with modulation of day-time sleep to once in the afternoon. Bipedal walking in upright position occurs in the third epoch, with development of a biphasic S-W cycle by the age of 4-5 years. Patients with infantile autism (IA), Rett syndrome (RTT), or Tourette syndrome (TS) show failure in the development of the first, second, or third epoch, respectively. Patients with IA fail to develop interlimb coordination; those with RTT, crawling and walking; and those with TS, walking in upright posture. Basic pathophysiology underlying these condition is failure in restricting atonia in REM stage; this induces dysfunction of the pedunculopontine nucleus and consequently dys- or hypofunction of the dopamine (DA) neurons. DA hypofunction in the developing brain, associated with compensatory upward regulation of the DA receptors causes psychobehavioral disorders in infancy (IA), failure in synaptogenesis in the frontal cortex and functional development of the motor and associate cortexes in late infancy through the basal ganglia (RTT), and failure in functional development of the prefrontal cortex through the basal ganglia (TS). Further, locomotion failure in early childhood causes failure in development of functional

    Fifty patients with unexplained vertigo (36) or lightheadedness (14) are evaluated, all of whom had abnormal ENGs and normal audiograms. Five hour insulin glucose tolerance tests were performance on all patients, with insulin levels being obtained fasting and at one-half, one, two, and three hours. The results of this investigation were remarkable. Borderline or abnormal insulin levels were discovered in 82% of patients; 90% were found to have either an abnormal glucose tolerance test or at least borderline insulin levels. The response to treatment in these dizzy patients was also startling, with appropriate low carbohydrate diets improving the patient's symptoms in 90% of cases. It is, therefore, apparent that the earliest identification of carbohydrate imbalance with an insulin glucose tolerance test is extremely important in the work-up of the dizzy patients.

    Full Text Available Spinal cord injury without radiological abnormality is rare in adults. Below we present a case report of 20 yrs old male with isolated cervical cord injury, without accompanying vertebral dislocation or fracture involving the spinal canal rim. He fell down on plain and smooth ground while carrying 40 kg weight overhead and developed quadriparesis with difficulty in respiration. Plain radiographs of the neck revealed no fractures or dislocations. MRI showed bulky spinal cord and an abnormal hyper intense signal on the T2W image from C2 vertebral body level to C3/4 intervertebral disc level predominantly in the anterior aspect of the cord The patient was managed conservatively with head halter traction and invasive ventilatory support for the initial 7 days period in the ICU. In our patient recovery was good and most of the neurological deficit improved over 4 weeks with conservative management.

    This work reports the first molecular analysis study of chicken anaemia virus (CAV) in backyard chickens in Africa using molecular cloning and sequence analysis to characterize CAV strains obtained from commercial chickens and Nigerian backyard chickens. Partial VP1 gene sequences were determined for three CAVs from commercial chickens and for six CAV variants present in samples from a backyard chicken. Multiple alignment analysis revealed that the 6% and 4% nucleotide diversity obtained respectively for the commercial and backyard chicken strains translated to only 2% amino acid diversity for each breed. Overall, the amino acid composition of Nigerian CAVs was found to be highly conserved. Since the partial VP1 gene sequence of two backyard chicken cloned CAV strains (NGR/CI-8 and NGR/CI-9) were almost identical and evolutionarily closely related to the commercial chicken strains NGR-1, and NGR-4 and NGR-5, respectively, we concluded that CAV infections had crossed the farm boundary.

    This study assesses the impact of equine infectious anaemia virus (EIAV) infection on the oxidant/antioxidant equilibrium of horses. Blood samples from 96 Romanian horses aged 1-25 years, were divided into different groups according to their EIAV-infection status, age, and time post-seroconversion. The effect of infection on oxidative stress was estimated by measuring enzymatic antioxidants (superoxide dismutase [SOD], glutathione peroxidase [GPx] and catalase), non-enzymatic antioxidants (uric acid and carotenoids), and lipid peroxidation (malondialdehyde [MDA]). Infection modified the oxidant/antioxidant equilibrium in the horses, influencing GPx and uric acid levels (Pstress imbalance, exhibiting a significant influence on both SOD and MDA concentrations in the blood (Pstress. Recently infected horses (horses >5 years old, represented the most vulnerable category in terms of oxidative stress, followed by recently infected animals stress in horses.

    Full Text Available Sub-Saharan Africa records each year about thirty-two million pregnant women living in areas of high transmission of Plasmodium falciparum causing malaria. The aim of this study was to carve out the prevalence of asymptomatic malaria among pregnant women and to emphasize its influence on haematological markers. The prevalence of Plasmodium falciparum asymptomatic infection among pregnant women was 30% and 24% with rapid detection test (RDT and microscopy, respectively. The prevalence of P. falciparum asymptomatic malaria was reduced among pregnant women using sulfadoxine-pyrimethamine's intermittent preventive treatment and 61% of them were anaemic. Anaemia was significantly more common in women infected with P. falciparum compared with the uninfected pregnant women. Most of the women had normal levels of homocysteine and low levels of folate, respectively. Therefore, the systematic diagnosis of malaria should be introduced to pregnant women as a part of the antenatal care.

    Chronic transfusions to maintain haemoglobin S (HbS) < or =30% are the mainstay of treatment for children with sickle cell anaemia (SCA) and previous stroke. This HbS target is often hard to maintain, however, and values achieved in current practice are unknown. In preparation for the Phase III Stroke With Transfusions Changing to Hydroxyurea (SWiTCH) trial, we collected data on 295 children with SCA and stroke who received transfusions at 23 institutions. The overall average pre-transfusion %HbS was 35 +/- 11% (institutional range 22-51%). Receiving scheduled transfusions on time was the most predictive variable for maintaining HbS at the < or =30% goal.

    Full Text Available Abstract Background The purpose of this study was to determine the incidence, risk factors and prognostic impact of anaemia and thrombocytopenia in patients with bone metastases (BM from prostate cancer. Methods Retrospective cohort study including 51 consecutive patients treated at a community hospital. Twenty-nine patients (57% received taxotere after diagnosis of BM. Results Haemoglobin (Hb ≤ 12.0 g/dL at BM detection was associated with shorter overall survival. During follow-up, 25 patients (49% experienced episodes with Hb 9/L. All of these had previously received blood transfusion. Median interval from Hb 9/L was 2.5 months. Survival after thrombocytopenia was short (3 weeks to 4 months. Haematuria and subdural haematoma were among the causes of death. Conclusions We found high rates of significant bone marrow failure in treatment-refractory patients. Both Hb 9/L predict for unfavourable survival.

    A nine-year-old Labrador retriever dog was admitted to the emergency unit of the Hebrew University Veterinary Teaching Hospital with acute-onset tremors and coma. It had recently ingested a large quantity of phenobarbital and had a high serum phenobarbital concentration. On this basis, a diagnosis of acute phenobarbital intoxication was made. Significant leucopenia, thrombocytopenia and mild anaemia developed on the third day after admission. The leucopenia resolved on day 6 and the thrombocytopenia on day 13. The red blood cell count remained low for the next month. The dog was discharged on day 13 at which time it was ambulatory but weak. It was completely recovered clinically eight days later. In summary, high levels of serum phenobarbital as a result of acute intoxication induced pancytopenia, which improved when the serum phenobarbital level was normalised.

  3. Sickle-cell anaemia: an explanation for the ancient myth of reincarnation in Nigeria.

    1983-08-27

    The belief in reincarnation, widely held in Nigeria for many centuries, has waned in the past 30 years. It is most probable that the "reincarnate" child had sickle-cell anaemia, since this disease would explain all the clinical features and natural history of "reincarnation". Most reincarnate children died of Plasmodium falciparum or bacterial infection. The prevailing high birth rate and familial predisposition almost ensured that another sickler was born to the family. The widespread introduction of antimalarial chemoprophylaxis and therapy, the recognition of sickle-cell disease, and some measure of improvement in health care and socioeconomic standards have resulted in an increase in life expectancy for children with HbSS and consequently near-total total extinction of the people's belief in reincarnation.

    Full Text Available Objectives. Sickle cell anaemia (SCA is one of the commonest genetic disorders in the world. It is characterized by anaemia, periodic attacks of thrombotic pain, and chronic systemic organ damage. Recent studies have suggested that individuals with SCA especially from developing countries are more likely to be iron deficient rather than have iron overload. The study aims to determine the iron status of SCA patients in Ilorin, Nigeria. Methods. A cross-sectional study of 45 SCA patients in steady state and 45 non-SCA controls was undertaken. FBC, blood film, sFC, sTfR, and sTfR/log sFC index were done on all subjects. Results. The mean patients’ serum ferritin (589.33 ± 427.61 ng/mL was significantly higher than the mean serum ferritin of the controls (184.53 ± 119.74 ng/mL. The mean serum transferrin receptor of the patients (4.24 ± 0.17 μg/mL was higher than that of the controls (3.96 ± 0.17 μg/mL (p=0.290. The mean serum transferrin receptor (sTfR/log serum ferritin index of the patients (1.65 ± 0.27 μg/mL was significantly lower than that of the control (1.82 ± 0.18 μg/mL (p=0.031. Conclusion. Iron deficiency is uncommon in SCA patients and periodic monitoring of the haematological, biochemical, and clinical features for iron status in SCA patients is advised.

    AIM: Anaemia caused by acute upper gastrointestinal bleeding is treated with blood transfusion or iron, but patients usually face a two-month recovery period from posthaemorrhage anaemia. This prospective, randomised, open,pilot study was designed to investigate whether recombinant human erythropoietin (Epoetin) therapy accelerate haematocrit increase in the post-bleeding recovery period.METHODS: We studied hospitalised patients admitted because of acute ulcer bleeding or haemorrhagic gastritis,who had a haematocrit of 27-33% and did not receive blood transfusions. One day after the endoscopic confirmation of cessation of bleeding, they were randomised either to erythropoietin (20 000 IU Epoetin alfa subcutaneously, on days 0, 4 and 6) plus iron (100 mg im, on days 1- 6, (G1) or iron only (G2). Haematocrit was measured on days 0, 6, 14,30, 45, and 60, respectively.RESULTS: One patient from G1 and two from G2 were lost to follow-up. Therefore, 14 and 13 patients from G1 and G2respectively were analysed. Demographic characteristics, serum iron, ferritin, total iron binding capacity, reticulocytes, and haematocrit were not significantly different at entry to the study.Median reticulocyte counts were significantly different between groups on day six (G1: 4.0, 3.0-6.4 vsG2: 3.5, 2.1-4.4%,P=0.03) and median haematocrit on day fourteen [G1: 35.9,30.7-41.0 vsG2: 32.5, 29.5-37.0% (median, range), P=0.04].CONCLUSION: Erythropoietin administration significantly accelerates correction of anemia after acute ulcer bleeding.The haematocrit gain is equivalent to one unit of transfused blood two weeks after the bleeding episode.

  8. Evidence that plasma concentration rather than dose per kilogram body weight predicts ribavirin-induced anaemia.

    Ribavirin in combination with interferon alpha-2 or pegylated interferon is the standard treatment for chronic hepatitis C. The current dosage recommendations for ribavirin are based on body weight (bw). Ribavirin is mainly eliminated by the kidneys and we have recently shown that ribavirin plasma concentrations are determined primarily by renal function. It is therefore reasonable to hypothesize that side-effects of ribavirin, i.e. anaemia, should be more closely related to plasma concentrations of ribavirin than to the dose per kg bw. A total of 108 consecutive patients eligible for treatment of chronic hepatitis C were studied. Ribavirin concentrations in plasma were measured by high-performance liquid chromatography (HPLC)-UV after solid-phase extraction in trough samples taken 4, 8 and 12 weeks after the treatment commenced. A total of 213 samples were obtained and the change in the haemoglobin level and the creatinine concentration was measured in addition to ribavirin. The dose of ribavirin per kg bw did not correlate with the drop in haemoglobin level induced by ribavirin. The concentration of ribavirin was non-linearly related to the drop in the haemoglobin level as revealed by fitting a standard Hill equation type dose-response curve. The half maximal drop in haemoglobin was obtained at 4.4 microm. The results from this study suggest that the anaemia induced by ribavirin depends primarily on the concentration of ribavirin, and not on the dose per kg bw. This lends further support to the idea that ribavirin should be dosed according to renal function.

  9. Widespread ocular use of topical chloramphenicol: is there justifiable concern regarding idiosyncratic aplastic anaemia?

    Science.gov (United States)

    McGhee, C N; Anastas, C N

    1996-02-01

    A theoretical but as yet not conclusively proved risk of chloramphenicol induced idiosyncratic aplastic anaemia exists with topical ophthalmic therapy, with the absolute, but highly improbable, maximum risk of death (equalling that of systemic therapy) being 1 in 50,000 to 90,000. To put this in realistic perspective, one must note that the comparable risk of fatal anaphylaxis resulting from penicillin therapy, from any route, is similar at 1 in 100,000. Indeed, it has been noted recently that with more than 200 million ocular chloramphenicol products dispensed in the UK in the past 10 years, only 11 reports (all non-fatal) of suspected topical chloramphenicol induced blood dyscrasia have been reported to the Committee on the Safety of Medicines since 1966. One also has to consider that inadvertent exposure to minute quantities of chloramphenicol (ng/ml) may occur through consumption of livestock that have been treated with chloramphenicol. Broad statements condemning topical chloramphenicol need to be tempered with its proved safety, tolerance, cost, and efficacy while acknowledging an extremely remote risk of the very serious adverse effect of drug induced aplastic anaemia. Risk-benefit assessment is the duty of all prescribing physicians and a decision to prescribe or not prescribe must be made on the basis of personal judgment and an awareness of the statistics in perspective. The only known factor to be associated with vulnerability in the case of topical chloramphenicol is family history. There is no evidence to date that suggests children are any more susceptible than adults.

    Abstract Rationale: It is widely believed that structural abnormalities of the brain contribute to the pathophysiology of schizophrenia. The parietal lobe is a central hub of multisensory integration, and abnormities in this region might account for the clinical features of schizophrenia. However, few cases of parietal encephalomalacia associated with schizophrenia have been described. Patient concerns and Diagnoses: In this paper, we present a case of a 25-year-old schizophrenia patient with abnormal parietal encephalomalacia. The patient had poor nutrition and frequently had upper respiratory infections during childhood and adolescence. She showed severe schizophrenic symptoms such as visual hallucinations for 2 years. After examining all her possible medical conditions, we found that the patient had a lesion consistent with the diagnosis of encephalomalacia in her right parietal lobe and slight brain atrophy. Interventions: The patient was prescribed olanzapine (10 mg per day). Outcomes: Her symptoms significantly improved after antipsychotic treatment and were still well controlled 1 year later. Lessons: This case suggested that parietal encephalomalacia, which might be caused by inflammatory and infectious conditions in early life and be aggravated by undernutrition, might be implicated in the etiology of schizophrenia.

    Full Text Available Healthy aging is one of the most important social issues. In this paper, we propose a method for abnormal activity detection without any manual labeling of the training samples. By leveraging the Field of View (FOV modulation, the spatio-temporal characteristic of human activity is encoded into low-dimension data stream generated by the ceiling-mounted Pyroelectric Infrared (PIR sensors. The similarity between normal training samples are measured based on Kullback-Leibler (KL divergence of each pair of them. The natural clustering of normal activities is discovered through a self-tuning spectral clustering algorithm with unsupervised model selection on the eigenvectors of a modified similarity matrix. Hidden Markov Models (HMMs are employed to model each cluster of normal activities and form feature vectors. One-Class Support Vector Machines (OSVMs are used to profile the normal activities and detect abnormal activities. To validate the efficacy of our method, we conducted experiments in real indoor environments. The encouraging results show that our method is able to detect abnormal activities given only the normal training samples, which aims to avoid the laborious and inconsistent data labeling process.

    The authors of the preceding articles raise legitimate questions about patient and staff rights and the unintended consequences of allowing ABC News to film inside teaching hospitals. We explain why we regard their fears as baseless and not supported by what we heard from individuals portrayed in the filming, our decade-long experience making medical documentaries, and the full un-aired context of the scenes shown in the broadcast. The authors don't and can't know what conversations we had, what documents we reviewed, and what protections we put in place in each televised scene. Finally, we hope to correct several misleading examples cited by the authors as well as their offhand mischaracterization of our program as a "reality" show.

    Full Text Available Abstract Background Asymptomatic malaria can be observed in both stable endemic areas and unstable transmission areas. However, although much attention has been given to acute malaria infections, relatively little attention has been paid to asymptomatic malaria. Nonetheless, because the asymptomatic host serves as a reservoir for the malaria parasite, asymptomatic malaria is now recognized as an important obstacle to malaria elimination. Asymptomatic malaria is also associated with anaemia, a global public health problem with serious consequences on human health as well as social and economic development. In Lao People’s Democratic Republic (Lao PDR, malaria, anaemia, and malnutrition are serious public health concerns. However, few studies have focused on the relationship between these variables. Therefore, this study investigated the relationship between asymptomatic malaria, growth status, and the prevalence of anaemia among children aged 120 months old or younger in rural villages in Lao PDR. Methods In December 2010 and March 2011, data were collected from five villages in Savannakhet province. Anthropometric measurements, blood samples, and malaria rapid diagnostic tests were conducted. The presence of malaria was confirmed with polymerase chain reaction assays for Plasmodium falciparum. Underweight status, stunting, and anaemia were defined according to World Health Organization standards. Results The mean age of participants (n = 319 was 88.3 months old (Standard Deviation: 20.6, ranged from 30–119 months old, and 20 participants (6.3 % had an asymptomatic malaria infection, 92 (28.8 % were anaemic, 123 (38.6 % were underweight, and 137 (42.9 % were stunted. Stunted children were more likely to be infected with asymptomatic malaria [odds ratio (OR 3.34, 95 % confidence interval (CI 1.25–8.93], and asymptomatic malaria was associated with anaemia [OR 5.17, 95 % CI 1.99–13.43].

    We describe an 18-year-old patient with psychomotor retardation and abnormally short metatarsi and metacarpals but no other signs of classic Refsum disease. Molecular analysis of the phytanoyl-coenzyme A hydroxylase gene revealed a homozygous deletion causing a frameshift. Surprisingly, L-pipecolic acid was elevated in plasma, and microscopy of the liver showed a reduced number of peroxisomes per cell and a larger average peroxisome size. These abnormal peroxisomes lacked catalase as did peroxisomes in fibroblasts of this patient. Such generalized peroxisomal abnormalities are not present in classic Refsum disease.

    Full Text Available When Su Cleyle and I first decided to start Evidence Based Library and Information Practice, one of the things we agreed upon immediately was that the journal be open access. We knew that a major obstacle to librarians using the research literature was that they did not have access to the research literature. Although Su and I are both academic librarians who can access a wide variety of library and information literature from our institutions, we belong to a profession where not everyone has equal access to the research in our field. Without such access to our own body of literature, how can we ever hope for practitioners to use research evidence in their decision making? It would have been contradictory to the principles of evidence based library and information practice to do otherwise.One of the specific groups we thought could use such an open access venue for discovering research literature was school librarians. School librarians are often isolated and lacking access to the research literature that may help them prove to stakeholders the importance of their libraries and their role within schools. Certainly, school libraries have been in decline and the use of evidence to show value is needed. As Ken Haycock noted in his 2003 report, The Crisis in Canada’s School Libraries: The Case for Reform and Reinvestment, “Across the country, teacher-librarians are losing their jobs or being reassigned. Collections are becoming depleted owing to budget cuts. Some principals believe that in the age of the Internet and the classroom workstation, the school library is an artifact” (9. Within this context, school librarians are looking to our research literature for evidence of the impact that school library programs have on learning outcomes and student success. They are integrating that evidence into their practice, and reflecting upon what can be improved locally. They are focusing on students and showing the impact of school libraries and

    In the second half of the 19th century, Jean-Martin Charcot (1825-1893) became famous for the quality of his teaching and his innovative neurological discoveries, bringing many French and foreign students to Paris. A hunger for recognition, together with progressive and anticlerical ideals, led Charcot to invite writers, journalists, and politicians to his lessons, during which he presented the results of his work on hysteria. These events became public performances, for which physicians and patients were transformed into actors. Major newspapers ran accounts of these consultations, more like theatrical shows in some respects. The resultant enthusiasm prompted other physicians in Paris and throughout France to try and imitate them. We will compare the form and substance of Charcot's lessons with those given by Jules-Bernard Luys (1828-1897), Victor Dumontpallier (1826-1899), Ambroise-Auguste Liébault (1823-1904), Hippolyte Bernheim (1840-1919), Joseph Grasset (1849-1918), and Albert Pitres (1848-1928). We will also note their impact on contemporary cinema and theatre.

    its high spatial and spectral resolution, it was possible to zoom into the very heart of this very massive star. In this innermost region, the observations are dominated by the extremely dense stellar wind that totally obscures the underlying central star. The AMBER observations show that this dense stellar wind is not spherically symmetric, but exhibits a clearly elongated structure. Overall, the AMBER observations confirm that the extremely high mass loss of Eta Carinae's massive central star is non-spherical and much stronger along the poles than in the equatorial plane. This is in agreement with theoretical models that predict such an enhanced polar mass-loss in the case of rapidly rotating stars. ESO PR Photo 06c/07 ESO PR Photo 06c/07 RS Ophiuchi in Outburst Several papers from this special feature focus on the later stages in a star's life. One looks at the binary system Gamma 2 Velorum, which contains the closest example of a star known as a Wolf-Rayet. A single AMBER observation allowed the astronomers to separate the spectra of the two components, offering new insights in the modeling of Wolf-Rayet stars, but made it also possible to measure the separation between the two stars. This led to a new determination of the distance of the system, showing that previous estimates were incorrect. The observations also revealed information on the region where the winds from the two stars collide. The famous binary system RS Ophiuchi, an example of a recurrent nova, was observed just 5 days after it was discovered to be in outburst on 12 February 2006, an event that has been expected for 21 years. AMBER was able to detect the extension of the expanding nova emission. These observations show a complex geometry and kinematics, far from the simple interpretation of a spherical fireball in extension. AMBER has detected a high velocity jet probably perpendicular to the orbital plane of the binary system, and allowed a precise and careful study of the wind and the shockwave

    Full Text Available Abstract Background Short stature is associated with several disorders including wide variations of chromosomal disorders and single gene disorders. The objective of this report is to present the cytogenetic findings in Indonesian patients with short stature. Methods G-banding and interphase/metaphase FISH were performed on short stature patients with and without other clinical features who were referred by clinicians all over Indonesia to our laboratory during the year 2003–2009. Results The results of chromosomal analysis of ninety seven patients (mean age: 10.7 years old were collected. The group of patients with other clinical features showed sex chromosome abnormalities in 45% (18/40 and autosomal abnormalities in 10% (4/40, whereas those with short stature only, 42.1% (24/57 had sex chromosome abnormalities and 1.75% (1/57 had autosomal abnormalities. The autosomal chromosomal abnormalities involved mostly subtelomeric regions. Results discrepancies between karyotype and FISH were found in 10 patients, including detection of low-level monosomy X mosaicism in 6 patients with normal karyotype, and detection of mosaic aneuploidy chromosome 18 in 1 patient with 45,XX,rob(13;14(q10;q10. Statistical analysis showed no significant association between the groups and the type of chromosomal abnormalities. Conclusion Chromosome abnormalities account for about 50% of the short stature patients. Wide variations of both sex and autosomal chromosomes abnormalities were detected in the study. Since three out of five patients had autosomal structural abnormalities involving the subtelomeric regions, thus in the future, subtelomeric FISH or even a more sensitive method such as genomic/SNP microarray is needed to confirm deletions of subtelomeric regions of chromosome 9, 11 and 18. Low-level mosaicism in normal karyotype patients indicates interphase FISH need to be routinely carried out in short stature patients as an adjunct to karyotyping.

  6. Manganese Abnormity in Holocene Sediments of the Bohai Sea

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Manganese abnormity has been observed in the Holocene sediments of the mud area of Bohai Sea. On the basis of grain size, chemical composition, heavy mineral content and accelerator mass spectrometry (AMS) 14C dating of foraminifer, relationships between manganese abnormity and sedimentation rates, material source, hydrodynamic conditions are probed. Manganese abnormity occurred during the Middle Holocene when sea level and sedimentation rates were higher than those at present. Sedimentary hiatus was not observed when material sources and hydrodynamic conditions were quite similar. Compared with the former period, the latter period showed a decrease in reduction environment and an inclination toward oxidation environment with high manganese content, whereas provenance and hydrodynamic conditions showed only a slight change. From the above observations, it can be concluded that correlation among manganese abnormity, material source, and hydrodynamic conditions is not obvious. Redox environment seems to be the key factor for manganese enrichment, which is mainly related to marine authigenic process.

    Many nail abnormalities have traditionally been described in association with rheumatoid arthritis (RA), but their specificity has never been assessed in a controlled study. Our purpose was to evaluate the frequency and the specificity of nail changes associated with RA in a case-controlled study including 50 patients suffering from RA and 50 controls. For each patient, a general skin examination was performed and the 20 nails were examined. The nail features were noted and classified. A chi 2 test or a Fisher test was used to compare the two groups. The only nail abnormalities significantly associated with RA were longitudinal ridging on nine or 10 finger nails (29 patients in the RA group vs. three in the controls, chi 2: P nail (24 patients vs. 10, chi 2: P nail changes were noticed but were not frequent enough to be significant. The presence of longitudinal ridging on the finger nails was significantly associated with RA.

    Neuroendocrine abnormalities are common in Parkinson's disease (PD) and include disruption of melatonin secretion, disturbances of glucose, insulin resistance and bone metabolism, and body weight changes. They have been associated with multiple non-motor symptoms in PD and have important clinical consequences, including therapeutics. Some of the underlying mechanisms have been implicated in the pathogenesis of PD and represent promising targets for the development of disease biomarkers and neuroprotective therapies. In this systems-based review, we describe clinically relevant neuroendocrine abnormalities in Parkinson's disease to highlight their role in overall phenotype. We discuss pathophysiological mechanisms, clinical implications, and pharmacological and non-pharmacological interventions based on the current evidence. We also review recent advances in the field, focusing on the potential targets for development of neuroprotective drugs in Parkinson's disease and suggest future areas for research.

    Meiotic anomalies, as reviewed here, are synaptic chromosome abnormalities, limited to germ cells that cannot be detected through the study of the karyotype. Although the importance of synaptic errors has been underestimated for many years, their presence is related to many cases of human male infertility. Synaptic anomalies can be studied by immunostaining of synaptonemal complexes (SCs), but in this case their frequency is probably underestimated due to the phenomenon of synaptic adjustment. They can also be studied in classic meiotic preparations, which, from a clinical point of view, is still the best approach, especially if multiplex fluorescence in situ hybridization is at hand to solve difficult cases. Sperm chromosome FISH studies also provide indirect evidence of their presence. Synaptic anomalies can affect the rate of recombination of all bivalents, produce achiasmate small univalents, partially achiasmate medium-sized or large bivalents, or affect all bivalents in the cell. The frequency is variable, interindividually and intraindividually. The baseline incidence of synaptic anomalies is 6-8%, which may be increased to 17.6% in males with a severe oligozoospermia, and to 27% in normozoospermic males with one or more previous IVF failures. The clinical consequences are the production of abnormal spermatozoa that will produce a higher number of chromosomally abnormal embryos. The indications for a meiotic study in testicular biopsy are provided.

    2011-12-01

    Full Text Available Abstract Background Levels of complement regulatory proteins (CrP on the surface of red blood cells (RBC decrease during severe malarial anaemia and as part of cell ageing process. It remains unclear whether CrP changes seen during malaria contribute to the development of anaemia, or result from an altered RBC age distribution due to suppressive effects of malaria on erythropoiesis. Methods A cross sectional study was conducted in the north-east coast of Tanzania to investigate whether the changes in glycosylphosphatidylinositol (GPI-anchored complement regulatory proteins (CD55 and CD59 contributes to malaria anaemia. Blood samples were collected from a cohort of children under intensive surveillance for Plasmodium falciparum parasitaemia and illness. Levels of CD55 and CD59 were measured by flow cytometer and compared between anaemic (8.08 g/dl and non- anaemic children (11.42 g/dl. Results Levels of CD55 and CD59 decreased with increased RBC age. CD55 levels were lower in anaemic children and the difference was seen in RBC of all ages. Levels of CD59 were lower in anaemic children, but these differences were not significant. CD55, but not CD59, levels correlated positively with the level of haemoglobin in anaemic children. Conclusion The extent of CD55 loss from RBC of all ages early in the course of malarial anaemia and the correlation of CD55 with haemoglobin levels support the hypothesis that CD55 may play a causal role in this disorder.

    Full Text Available Background. Anaemia with an estimated prevalence of 35–75% among pregnant women is a major cause of maternal deaths in Nigeria. Objective. To determine the prevalence of anaemia, associated sociodemographic factors and red cell morphological pattern among pregnant women during booking at the University Teaching Hospital, Uyo. Material and Methods. A cross-sectional analytical study of 400 women at the booking clinic over a 16-week period. The packed cell volume and red cell morphology of each pregnant woman were determined. Their biodata, obstetric and medical histories, and results of other routine investigations were obtained with questionnaires and analyzed with SPSS Package version 17.0. Results. The mean packed cell volume was 31.8% ±3.2 and 54.5% of the women were anaemic. The commonest blood picture was microcytic hypochromia and normocytic hypochromia suggesting iron deficiency anaemia. Anaemia was significantly and independently related to a history of fever in the index pregnancy (OR=0.4; P=0.00; 95% CI=0.3–0.7, HIV positive status (OR=0.2; P=0.01; 95% CI=0.1–0.6, and low social class (OR=0.3; P=0.00; 95% CI=0.2–0.7. Conclusion. Women need to be economically empowered and every pregnant woman should be encouraged to obtain antenatal care, where haematinics supplementation can be given and appropriate investigations and treatment of causes of fever and management of HIV can be instituted.

    Abnormal heading in hybrid rice production has caused great economic loss in recent years, but the genetic basis of this phenomenon remains elusive. In this study, we developed four testcross populations using 38 introgression lines (ILs) from Shuhui 527 (SH527)/Fuhui 838 (FH838)//SH527 population as male parents and four male sterile lines (MSLs; namely II-32A, Xieqingzao A, Gang 46A and Jin 23A) as female parents. Progeny testing allowed us to identify 55 abnormal heading combinations in Hefei, but had late heading date in Hangzhou and Guangzhou of China. By one-and two-way analysis of variance, a total of 21 QTLs and 31 pairs of epistatic QTLs associated with photosensitivity were identified in the four populations, respectively. Genotypic analysis showed that the IL parent of most abnormal heading combinations showed some introgressions at markers RM331 and RM3395 on chromosome 8 (strongly associated with the known genes OsHAP3H/DTH8/Ghd8/LHD1) of donor FH838 alleles, and these two markers were also identified as affecting photosensitivity. The observation that the recipient parent (SH527), donor parent (FH838), their testcross combinations with four MSLs, and the IL parents of abnormal heading combinations had normal heading date in Hefei suggested that OsHAP3H/DTH8/Ghd8/LHD1 showed no independent regulation on abnormal heading in the abnormal heading combinations. It is noteworthy that complex epistasis among RM331 or RM3395 with other loci, including dominant × additive, additive × dominant, and dominant × dominant epistases, were identified only in the four testcross populations of the current study, but not in the SH527/FH838//SH527 population, suggesting the cause of abnormal heading in abnormal heading combinations in Hefei and delayed heading in Hangzhou and Guangzhou.

    Full Text Available Background/Aim. We evaluate the impact of combined pentoxifylline and high-dose vitamins E to standard antiviral treatment on RBV-induced haemolytic anaemia. Patients and Methods. Selected 200 naïve chronic HCV patients, were randomized to receive either the standard antiviral therapy (peginterferon α-2b and RBV plus pentoxifylline (800 mg and high-dose vitamin E (1000 iu daily (combined group or received standard antiviral therapy plus placebo only (control group. They were followed up during treatment course and for 6 months posttreatment to assess the occurrence of anaemia and virological response, respectively. Results. RBV dose modification due to anaemia were significantly less in combined group (8.5 versus 21.5%. P<.05.Withdrawal, secondary to sever anemia (Hb<8.5 gm%, was recorded only in 6 (28.6% patients of the control group. Both (ETR and (SVR were significantly higher in combined group than control group by both intention-to-treat analysis (71 versus 56%, P<.05 and 66 versus 49%, P<.05 and per-protocol analysis (85.5 versus 70.9%, P<.05 and 79.5 versus 62%, P<.05. Conclusion. Pentoxifylline and vitamin E can ameliorate RBV-associated haemolysis; improve compliance and virologic clearance when combined with the standard antiviral therapy in patients with chronic hepatitis C.

    Full Text Available BACKGROUND: Malaria and anaemia are the leading causes of morbidity and mortality in children in sub-Saharan Africa. We have investigated the effect of intermittent preventive treatment with sulphadoxine-pyrimethamine or artesunate plus amodiaquine on anaemia and malaria in children in an area of intense, prolonged, seasonal malaria transmission in Ghana. METHODS: 2451 children aged 3-59 months from 30 villages were individually randomised to receive placebo or artesunate plus amodiaquine (AS+AQ monthly or bimonthly, or sulphadoxine-pyrimethamine (SP bimonthly over a period of six months. The primary outcome measures were episodes of anaemia (Hb1 year old when they received IPTc compared to the placebo group. However the incidence of malaria in the post intervention period was higher in children who were <1 year old when they received AS+AQ monthly compared to the placebo group. INTERPRETATION: IPTc is safe and efficacious in reducing the burden of malaria in an area of Ghana with a prolonged, intense malaria transmission season. TRIAL REGISTRATION: ClinicalTrials.gov NCT00119132.

    1989-01-01

    In a survey of a random sample of the adult population (aged 25-64 yr) from Ghent and Charleroi (n = 1693), 103 (6.1%) showed ECG-abnormalities suggestive of coronary heart disease (Minnesota code I, IV, or V); prevalence was equal in men (6.2%) as in women (6.0%). In men, 30% of ECG-abnormalities suggested an old myocardial infarction as compared to 23.4% in women. Men with abnormal ECG had a positive history of acute myocardial infarction in 23%, as compared to 23.4% in women. Multivariate discriminant function analysis shows that men with abnormal ECG are older, have a higher systolic blood pressure and were more often married. Women with ECG abnormalities were significantly older, had a lower HDL-level and were less educated. So, although the prevalence of ECG abnormalities is almost similar between sexes, they correlate differently with antecedents of infarction and are poorly related to different sets of risk factors in men as compared to women.

  1. High risk of severe anaemia after chlorproguanil-dapsone+artesunate antimalarial treatment in patients with G6PD (A- deficiency.

    Directory of Open Access Journals (Sweden)

    Caterina I Fanello

    Full Text Available BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD deficiency is the most common inherited human enzyme defect. This deficiency provides some protection from clinical malaria, but it can also cause haemolysis after administration of drugs with oxidant properties. METHODS: The safety of chlorproguanil-dapsone+artesunate (CD+A and amodiaquine+sulphadoxine-pyrimethamine (AQ+SP for the treatment of uncomplicated P. falciparum malaria was evaluated according to G6PD deficiency in a secondary analysis of an open-label, randomized clinical trial. 702 children, treated with CD+A or AQ+SP and followed for 28 days after treatment were genotyped for G6PD A- deficiency. FINDINGS: In the first 4 days following CD+A treatment, mean haematocrit declined on average 1.94% (95% CI 1.54 to 2.33 and 1.05% per day (95% CI 0.95 to 1.15 respectively in patients with G6PD deficiency and normal patients; a mean reduction of 1.3% per day was observed among patients who received AQ+SP regardless of G6PD status (95% CI 1.25 to 1.45. Patients with G6PD deficiency recipients of CD+A had significantly lower haematocrit than the other groups until day 7 (p = 0.04. In total, 10 patients had severe post-treatment haemolysis requiring blood transfusion. Patients with G6PD deficiency showed a higher risk of severe anaemia following treatment with CD+A (RR = 10.2; 95% CI 1.8 to 59.3 or AQ+SP (RR = 5.6; 95% CI 1.0 to 32.7. CONCLUSIONS: CD+A showed a poor safety profile in individuals with G6PD deficiency most likely as a result of dapsone induced haemolysis. Screening for G6PD deficiency before drug administration of potentially pro-oxidants drugs, like dapsone-containing combinations, although seldom available, is necessary.

    Schäfer, M L

    1983-01-01

    The present paper deals with the problematic nature of the phenomenological grasping of the consciousness of the body and its pathological modifications. The reasoning is oriented by the doctrine of Husserl of the so-called sentiments as the fundamentals of the experience of the own body. This basic approach does not only seem to be basically for a psychology of the consciousness of the body, but also to give the theoretical-conceptual structure for a great number of psychopathological modifications. Subsequent to a criticism of the conventional use of the term 'hallucination of the body' we attempt to chart elements of a scheme of the abnormal consciousness of the body.

    Full Text Available Objective: The present study evaluated the prevalence of anaemia and its determinants in one- and three-year-old children from the Capricorn District of Limpopo Province, South Africa. Methods: A prospective cohort study conducted in rural villages in the Capricorn District of Limpopo Province, South Africa. At birth, a cohort of 219 children was followed until they were one and three years of age. Data collected included the children’s anthropometric measurements, blood for biochemical analysis (full blood count, ferritin, folate and vitamin B12 and socio-demographic status.Results: At one year, anaemia (Hb < 11 g/dL was present in 52% of the children, decreasing to 22% by the third year. Iron deficiency (ferritin < 12 µg/mL was common in these children (39% and 33% at one year and three years, respectively particularly in the presence of anaemia. Folate and vitamin B12 deficiencies (< 5 ng/mL and < 145 pg/mL, respectively were common at one year, with the children accumulating enough vitamin B12 by three years; however, folate deficiency levels remained fairly constant between the two time points.Conclusion: There was a high prevalence of anaemia in the study participants at one year and three years of age. Factors that increased the risk of anaemia at three years were: a mother with only a primary school education, anaemia at one year, male gender, overweight, and combined overweight and stunting. Protective factors against anaemia were having a younger mother who served as the main caregiver.

  5. Chromosomal phenotypes and submicroscopic abnormalities

    Devriendt Koen

    2004-01-01

    Full Text Available Abstract The finding, during the last decade, that several common, clinically delineated syndromes are caused by submicroscopic deletions or, more rarely, by duplications, has provided a powerful tool in the annotation of the human genome. Since most microdeletion/microduplication syndromes are defined by a common deleted/duplicated region, abnormal dosage of genes located within these regions can explain the phenotypic similarities among individuals with a specific syndrome. As such, they provide a unique resource towards the genetic dissection of complex phenotypes such as congenital heart defects, mental and growth retardation and abnormal behaviour. In addition, the study of phenotypic differences in individuals with the same microdeletion syndrome may also become a treasury for the identification of modifying factors for complex phenotypes. The molecular analysis of these chromosomal anomalies has led to a growing understanding of their mechanisms of origin. Novel tools to uncover additional submicroscopic chromosomal anomalies at a higher resolution and higher speed, as well as the novel tools at hand for deciphering the modifying factors and epistatic interactors, are 'on the doorstep' and will, besides their obvious diagnostic role, play a pivotal role in the genetic dissection of complex phenotypes.

    Full Text Available Background. Sickle cell anaemia (SCA is an inherited condition whose clinical manifestations arise from the tendency of haemoglobin to polymerize and deform red blood cells into characteristic sickle shape. Allogeneic bone marrow transplantation offers a cure. The aim of this study was to determine the level of awareness, knowledge, and acceptance of this beneficial procedure in Nigeria. Materials and Methods. This multicentre cross-sectional study was conducted in 7 tertiary hospitals in Nigeria in 2015. Approval was obtained from each institution’s research and ethics committee. A pretested structured questionnaire was administered to respondents aged 18 years and above and to the parents or guardians of those below 18 years of age. Results. There were 265 respondents comprising 120 males and 145 females. One hundred and seventy-one (64.5% respondents were aware of BMT for the treatment of SCA. About 67.8% (116 of 171 of those who were aware believed SCA can be cured with BMT (p=0.001 and 49.7% (85 of 171 of the respondents accepted BMT (p=0.001. Conclusion. Awareness of BMT in Nigeria is low when compared with reports from developed countries. The knowledge is poor and acceptance is low. With adequate information, improved education, and psychological support, more Nigerians will embrace BMT.

    Archived sera from Atlantic salmon (Salmo salar) that returned to the Penobscot River (Maine), Merrimack River (Massachusetts), and Connecticut River (in Massachusetts) from 1995 to 2002 were analysed for antibodies against infectious salmon anaemia virus (ISAV) using an enzyme-linked immunosorbent assay (ELISA). Up to 60 samples were archived per river system per year. In a given year, the number of fish sampled by ELISA for ISAV antibodies in the Penobscot River ranged from 2.9 to 11.2, and the range of salmon sampled in the Merrimack River and the Connecticut River was 31.3-100 and 20.0-67.5, respectively. Archived sera were not available for the 1995 and 2002 year classes from the Connecticut River. In all, 1141 samples were processed; 14 serum samples tested positive for antibodies to ISAV. In the Penobscot River, serum from one fish tested positive in each of the 1995 and 1999 year-class returns, and sera from two fish tested positive in the 1998 returns. In the Merrimack River, sera from four fish tested positive in each of the 1996 and 1997 returns, and sera from two fish were positive in the 2002 return. None of the archived sera from Atlantic salmon that returned to the Connecticut River tested positive. ?? 2009 United States Government, Department of the Interior.

    Full text: We present a case of a 39 year old previously well woman who developed carbimazole-induced acute aplastic anaemia. Following 6 weeks of carbimazole for Grave`s disease she presented with fever, sore throat and lethargy and was found to be pancytopaenic. Haemoglobin fell to 79g/l (normal>120g/l), neutrophils to an undetectable level and platelets to 4,000/ml (normal>150,000/ml). From the MIRD schema it was estimated that a therapeutic dose of 444 MBq (12mCi) to treat her hyperthyroidism would deliver a red marrow radiation dose of about 30 mSv, at least an order of magnitude below any expected demonstrable deleterious effect on the marrow. Subsequently a dose of 444 MBq of I-131 was given and within 2 weeks the marrow had begun to recover, eventually to normal. This case would support the use of 1-131 for hyperthyroidism in carbimazole-induced marrow aplasia, even in profoundly depressed marrow

  9. Recommendations for centres of expertise in rare anaemias. The ENERCA White Book

    2014-12-01

    Full Text Available The Community added value of Centres of Expertise (CoE and European Reference Networks (ERN is particularly high for rare diseases (RD due to the rarity of these conditions, which implies both a small number of patients and scarcity of expertise within a single country. Gathering expertise at the European level is therefore, paramount in order to ensure equal access to accurate information, appropriate and timely diagnosis and high quality clinical care and follow up for patients with rare diseases. This applies particularly to rare anaemias due to the high number of different rare diseases that constitute this group. In this context, the European Network for Rare and Congenital Anaemias (ENERCA, co-financed by the European Commission, was created in 2002 with the aim of prevention and management of rare anaemias (RA and the development and promotion of policies to improve the well-being of European Union citizens. The ENERCA White Book is a position paper, developed as a deliverable of the ENERCA (phase 3 project that intends to contribute to the creation of a ERN in RA (ERN-RA by preparation of the recommendations and, in particular, the definition of the criteria that CoE, local centres (LC and their interrelations have to fulfil as healthcare providers. It has been nourished by all the activities that have been performed over the past ten years within the ENERCA framework. The White Book is addressed to authorities in charge of the identifying CoE, as an essential requirement for the official recognition of the ERN, to European and national health authorities, Healthcare centres and health professionals, as well as to all other stakeholders interested in RA. It is also addressed to the patients, as a way to empower their community in this process. One particular characteristic of the White Book is the integration of the three main aspects of a CoE: a ethical and legal frameworks to ensure the non-discrimination and non-stigmatisation of rare

    Background. Sickle cell anaemia (SCA) is an inherited condition whose clinical manifestations arise from the tendency of haemoglobin to polymerize and deform red blood cells into characteristic sickle shape. Allogeneic bone marrow transplantation offers a cure. The aim of this study was to determine the level of awareness, knowledge, and acceptance of this beneficial procedure in Nigeria. Materials and Methods. This multicentre cross-sectional study was conducted in 7 tertiary hospitals in Nigeria in 2015. Approval was obtained from each institution's research and ethics committee. A pretested structured questionnaire was administered to respondents aged 18 years and above and to the parents or guardians of those below 18 years of age. Results. There were 265 respondents comprising 120 males and 145 females. One hundred and seventy-one (64.5%) respondents were aware of BMT for the treatment of SCA. About 67.8% (116 of 171) of those who were aware believed SCA can be cured with BMT (p = 0.001) and 49.7% (85 of 171) of the respondents accepted BMT (p = 0.001). Conclusion. Awareness of BMT in Nigeria is low when compared with reports from developed countries. The knowledge is poor and acceptance is low. With adequate information, improved education, and psychological support, more Nigerians will embrace BMT.

  11. Localised Infection of Atlantic Salmon Epithelial Cells by HPR0 Infectious Salmon Anaemia Virus.

    Directory of Open Access Journals (Sweden)

    Maria Aamelfot

    Full Text Available Infectious salmon anaemia (ISA is an important, systemic viral disease of farmed Atlantic salmon, Salmo salar L. Endothelial cells are the main target cells for highly virulent HPR-deleted ISA virus (ISAV types. Here we examine the pathogenesis of non-virulent ISAV HPR0 infections, presenting evidence of an epithelial tropism for this virus type, including actual infection and replication in the epithelial cells. Whereas all HPR0 RT-qPCR positive gills prepared for cryosection tested positive by immunohistochemistry (IHC and immunofluorescent labelling, only 21% of HPR0 RT-qPCR positive formalin-fixed paraffin-embedded gills were IHC positive, suggesting different methodological sensitivities. Only specific epithelial cell staining was observed and no staining was observed in endothelial cells of positive gills. Furthermore, using an ISAV segment 7 RT-PCR assay, we demonstrated splicing of HPR0, suggesting initial activation of the replication machinery in the epithelial gill cells. Immunological responses were investigated by the expression of interferon-related genes (e.g. Mx and γIP and by ELISA for presence of anti-ISAV antibodies on samples taken sequentially over several months during an episode of transient HPR0 infection. All fish revealed a variable, but increased expression of the immunological markers in comparison to normal healthy fish. Taken together, we conclude that HPR0 causes a localized epithelial infection of Atlantic salmon.

    Haematological and genetic observations have been made on 71 SS Eti-Turk patients and their relatives from Cukurova (southern Turkey) and of immigrant families in The Netherlands. Similar data were collected for 25 Black patients and their relatives from Surinam, Netherlands Antilles, and Kenya. Haematological and clinical results were the same for both groups; the haemolytic anaemia in the Turkish patients was as severe as in the others. Haplotyping, involving nine restriction sites, identified haplotype 19 (Antonarakis et al, 1984) as the major type among the Eti-Turks; this chromosome has previously primarily been observed among SS patients from West Africa. The suggestion that the beta S-chromosome among Eti-Turks originates from that area is supported by a relatively high incidence of alpha-thalassaemia-2 (the 3.7 kb deletion), also frequently present in the Black population of West Africa, and by the absence of other major haplotypes, such as types 20 and 3, characteristic for the beta S-chromosome in the population of Central Africa and Kenya, and in Senegal, respectively. The Saudi Arabian type of beta S chromosome in association with the haplotype 19 beta S chromosome was present in only one Eti-Turk patient; this 30-year-old female was mildly affected and exhibited a high level of fetal haemoglobin.

    One key function of intelligent transportation systems is to automatically detect abnormal traffic phenomena and to help further investigations of the cause of the abnormality. This paper describes a robust principal components analysis (RPCA)-based abnormal traffic flow pattern isolation and loop detector fault detection method. The results show that RPCA is a useful tool to distinguish regular traffic flow from abnor-mal traffic flow patterns caused by accidents and loop detector faults. This approach gives an effective traffic flow data pre-processing method to reduce the human effort in finding potential loop detector faults. The method can also be used to further investigate the causes of the abnormality.

  14. Characterization of abnormal grain coarsening in Alloy 718

    2014-01-01

    Full Text Available Even though the phenomenon of abnormal grain coarsening (AGC or “exploded grains” has been known to occur in Alloy 718 industrial forgings there is still no satisfactory explanation for it. For this reason, detailed microstructure analysis has been carried out in normal and abnormal regions. Electron Backscatter Diffraction (EBSD was employed to determine grain size, boundary distribution and measure stored energy, while backscattered imagining in a FEGSEM was used to measure δ precipitate size and morphology. It was found that abnormal regions show almost 3 times as many twin boundaries compared to a normal region. In addition, the δ phase morphologies differ very significantly when comparing these two different regions. Normal regions display δ phase with a plate like nature, whereas in abnormal regions, δ particles appear to be more spherical. Furthermore, there are clear indications of differences in δ volume fractions between the two regions. Whilst in normal regions the δ phase is found predominantly at grain boundaries, in abnormal regions the δ is also found within grains. Both backscatter images and EBSD scans indicate that there are higher levels of stored energy within the normal regions, compared to the abnormal regions. These observations suggest that AGC occurs in regions where dynamic recrystallization does not happen and where recrystallization during solution heat treatment is affected by the local particle distribution.

    Highlights: • Cognitive impairments are frequently observed in treated NFA patients. • NFA patients with cognitive impairments do not show brain abnormalities on MRI more frequently than patients without cognitive impairments. • The absence of brain abnormalities on brain MRI does not exclude impairments of cognition. - Abstract: Purpose: The extent to which cognitive dysfunction is related to specific brain abnormalities in patients treated for pituitary macroadenoma is unclear. Therefore, we compared brain abnormalities seen on Magnetic Resonance Imaging (MRI) in patients treated for nonfunctioning pituitary macroadenoma (NFA) with or without impairments in cognitive functioning. Methods: In this cross-sectional design, a cohort of 43 NFA patients was studied at the University Medical Center Groningen. White matter lesions (WMLs), cerebral atrophy, (silent) brain infarcts and abnormalities of the temporal lobes and hippocampi were assessed on pre-treatment and post-treatment MRI scans. Post-treatment cognitive examinations were performed using a verbal memory and executive functioning test. We compared our patient cohort with large reference populations representative of the Dutch population. Results: One or more impairments on both cognitive tests were frequently observed in treated NFA patients. No treatment effects were found with regard to the comparison between patients with and without impairments in executive functioning. Interestingly, in patients with one or more impairments on verbal memory function, treatment with radiotherapy had been given more frequently (74% in the impaired group versus 40% in the unimpaired group, P = 0.025). Patients with or without any brain abnormality on MRI did not differ in verbal memory or executive functioning. Conclusions: Brain abnormalities on MRI are not observed more frequently in treated NFA patients with impairments compared to NFA patients without impairments in verbal memory or executive functioning

    2014-01-01

    Full Text Available Magnetic resonance imaging (MRI techniques have been used to quantitatively assess focal and network abnormalities. Idiopathic generalized epilepsy (IGE is characterized by bilateral synchronous spike–wave discharges on electroencephalography (EEG but normal clinical MRI. Dysfunctions involving the neocortex, particularly the prefrontal cortex, and thalamus likely contribute to seizure activity. To identify possible morphometric and functional differences in the brains of IGE patients and normal controls, we employed measures of thalamic volumes, cortical thickness, gray–white blurring, fractional anisotropy (FA measures from diffusion tensor imaging (DTI and fractional amplitude of low frequency fluctuations (fALFF in thalamic subregions from resting state functional MRI. Data from 27 patients with IGE and 27 age- and sex-matched controls showed similar thalamic volumes, cortical thickness and gray–white contrast. There were no differences in FA values on DTI in tracts connecting the thalamus and prefrontal cortex. Functional analysis revealed decreased fALFF in the prefrontal cortex (PFC subregion of the thalamus in patients with IGE. We provide minimum detectable effect sizes for each measure used in the study. Our analysis indicates that fMRI-based methods are more sensitive than quantitative structural techniques for characterizing brain abnormalities in IGE.

    Full Text Available Introduction: A retrocervical subcutaneous collection of fluid at 11-14 weeks of gestation, can be visualized by ultrasound as nuchal translucency (NT. Objective. To examine the distribution of fetal nuchal translucency in low risk population, to determine the detection rate of chromosomal abnormalities in the population of interest based on maternal age and NT measurement. Method. Screening for chromosomal defects, advocated by The Fetal Medicine Foundation (FMF, was performed in 1,341 pregnancies in the period January 2000 - April 2004. Initial risk for chromosomal defects (based on maternal and gestational age and corrected risk, after the NT measurement, were calculated. Complete data were collected from 1,048 patients. Results. Out of 1,048 pregnancies followed, 8 cases of Down’s syndrome were observed, 7 were detected antenatally and 6 out of 7 were detected due to screening that combines maternal age and NT measurement. According to our results, sensitivity of the screening for aneuploidies based on maternal age alone was 12.5% and false positive rate 13.1%, showing that screening based on NT measurement is of great importance. Screening by a combination of maternal age and NT, and selecting a screening-positive group for invasive testing enabled detection of 75% of fetuses with trisomy 21. Conclusion. In screening for chromosomal abnormalities, an approach which combines maternal age and NT is effective and increases the detection rate compared to the use of any single test. .

    Prior diffusion tensor imaging (DTI) studies examining schizotypal personality disorder (SPD) and schizophrenia, separately have shown that compared with healthy controls (HCs), patients show frontotemporal white matter (WM) abnormalities. This is the first DTI study to directly compare WM tract coherence with tractography and fractional anisotropy (FA) across the schizophrenia spectrum in a large sample of demographically matched HCs (n = 55), medication-naive SPD patients (n = 49), and unmedicated/never-medicated schizophrenia patients (n = 22) to determine whether (a) frontal-striatal-temporal WM tract abnormalities in schizophrenia are similar to, or distinct from those observed in SPD; and (b) WM tract abnormalities are associated with clinical symptom severity indicating a common underlying pathology across the spectrum. Compared with both the HC and SPD groups, schizophrenia patients showed WM abnormalities, as indexed by lower FA in the temporal lobe (inferior longitudinal fasciculus) and cingulum regions. SPD patients showed lower FA in the corpus callosum genu compared with the HC group, but this regional abnormality was more widespread in schizophrenia patients. Across the schizophrenia spectrum, greater WM disruptions were associated with greater symptom severity. Overall, frontal-striatal-temporal WM dysconnectivity is attenuated in SPD compared with schizophrenia patients and may mitigate the emergence of psychosis.

  1. Abnormal Returns and Contrarian Strategies

    Full Text Available We test the hypothesis that strategies which are long on portfolios of looser stocks and short on portfolios of winner stocks generate abnormal returns in Brazil. This type of evidence for the US stock market was interpreted by The Bondt and Thaler (1985 as reflecting systematic evaluation mistakes caused by investors overreaction to news related to the firm performance. We found evidence of contrarian strategies profitability for horizons from 3 months to 3 years in a sample of stock returns from BOVESPA and SOMA from 1986 to 2000. The strategies are more profitable for shorter horizons. Therefore, there was no trace of the momentum effect found by Jagadeesh and Titman (1993 for the same horizons with US data. There are remaing unexplained positive returns for contrarian strategies after accounting for risk, size, and liquidity. We also found that the strategy profitability is reduced after the Real Plan, which suggests that the Brazilian stock market became more efficient after inflation stabilization.

    A 1-month-old boy with shortness of extremities on prenatal US was referred to our department with a provisional diagnosis of achondroplasia. His height was normal but he had short extremities and platyspondyly, premature carpal epiphyses on both hands, and short tubular bones with irregular metaphyses on radiographs. Re-evaluation of the patient at the age of 1 year revealed very short height and premature calcification of the costal cartilages and epiphyses. Spondylometaepiphyseal dysplasia (SMED), short limb-abnormal calcification type was diagnosed. This condition is a very rare autosomal recessively inherited disorder, and most of the patients die in early childhood due to neurological involvement. At the age of 2 years and 5 months, a CT scan showed narrowing of the cervical spinal canal. One month later he died suddenly because of spinal cord injury. In conclusion early diagnosis is very important because the recurrence risk is high and patients may die due to early neurological complications. The time of onset of abnormal calcifications, a diagnostic finding of the disease, is at the age of around 1 year in most patients. When abnormal calcifications are not yet present, but radiological changes associated with SMED are present, this rare disease must be considered. (orig.)

    The hallmark of neuronopathic Gaucher disease (GD) is oculomotor abnormalities, but ophthalmological assessment is difficult in uncooperative patients. Chromatic pupillometry is a quantitative method to assess the pupillary light reflex (PLR) with minimal patient cooperation. Thus, we investigated whether chromatic pupillometry could be useful for neurological evaluations in GD. In our neuronopathic GD patients, red light-induced PLR was markedly impaired, whereas blue light-induced PLR was relatively spared. In addition, patients with non-neuronopathic GD showed no abnormalities. These novel findings show that chromatic pupillometry is a convenient method to detect neurological signs and monitor the course of disease in neuronopathic GD. PMID:25356393

    Locating the assignable causes by use of the abnormal patterns of control chart is a widely used technology for manufacturing quality control. If there are uncertainties about the occurrence degree of abnormal patterns, the diagnosis process is impossible to be carried out. Considering four common abnormal control chart patterns, this paper proposed a characteristic numbers based recognition method point by point to quantify the occurrence degree of abnormal patterns under uncertain conditions and a fuzzy inference system based on fuzzy logic to calculate the contribution degree of assignable causes with fuzzy abnormal patterns. Application case results show that the proposed approach can give a ranked causes list under fuzzy control chart abnormal patterns and support the abnormity eliminating.

    Objectives Blood rheology plays a key role in the pathophysiology of sickle cell anaemia (SS) and sickle cell haemoglobin C disease (SC), but its evolution over the lifespan is unknown. Materials and Methods Blood viscosity, red blood cell (RBC) deformability and aggregation, foetal haemoglobin (HbF) and haematocrit were measured in 114 healthy individuals (AA), 267 SS (161 children + 106 adults) and 138 SC (74 children + 64 adults) patients. Results Our results showed that 1) RBC deformability is at its maximal value during the early years of life in SS and SC populations, mainly because HbF level is also at its peak, 2) during childhood and adulthood, hydroxycarbamide treatment, HbF level and gender modulated RBC deformability in SS patients, independently of age, 3) blood viscosity is higher in older SS and SC patients compared to younger ones and 4) haematocrit decreases as SS patients age. Conclusion The hemorheological changes detected in older patients could play a role in the progressive development of several chronic disorders in sickle cell disease, whose prevalence increases with age. Retarding these age-related haemorheological impairments, by using suitable drugs, may minimize the risks of vaso-occlusive events and chronic disorders. PMID:27355589

    A fatigued 8-year-old boy was found to have sideroblastic anaemia (haemoglobin 7.8 g/dL) which over time became transfusion dependent. Subtle neurological dysfunction, initially manifesting as mild spastic diplegia, was slowly progressive and ultimately led to wheelchair dependence. Elevated plasma lactate and urinary 3-methylglutaconate led to a muscle biopsy which confirmed partial complex IV deficiency. PCR in leucocytes and muscle was negative for mitochondrial DNA (mtDNA) deletions. Faltering growth prompted an insulin tolerance test which confirmed growth hormone sufficiency and adrenal insufficiency. Plasma renin was elevated and adrenal androgens were low, suggesting primary adrenal insufficiency. Glucocorticoid and mineralocorticoid replacement therapy was initiated. A renal tubular Fanconi syndrome and diabetes mellitus developed subsequently. Sideroblastic anaemia and primary adrenal insufficiency, both individually and collectively, are associated with mtDNA deletion; however, absence of the same does not exclude the possibility that sideroblastic anaemia and primary adrenal insufficiency are of mitochondrial origin.

    Several authors have described a particular potential of automated depolarization analysis in detecting malaria infection as part of the routine full blood count (FBC) performed by the Cell-Dyn 4000 analyzer. In these cases, abnormal depolarizing patterns are due to the presence of leukocyte-associated malaria hemozoin, a pigment which depolarizes the laser light. In this report we describe samples from three individual patients who did not have malaria infection but showed abnormal depolarizing events. Further investigation determined that these samples were from patients infected by the nematode Mansonella perstans. The observed depolarizing pattern consisted of a normal depolarizing eosinophil population and in addition an abnormal depolarizing population that showed a close "linear" relationship between "granularity" (90 degrees depolarization) and "lobularity" (90 degrees polarization). This atypical population was smaller than normal leukocytes and thus clearly different from the patterns associated with malaria infection. Abnormal depolarization patterns of M. perstans clearly do not reflect leukocyte-associated malaria hemozoin. It is possible however that the erythrocyte-lysing agent used to facilitate leukocyte analysis by the instrument may have caused microfilaria fragmentation and thus the distinctive "straight-line" features of the abnormal scatter plots

    To assess the risk of major congenital abnormalities associated with specific antiepileptic drug regimens, a large retrospective cohort study was performed. The study comprised 1,411 children born between 1972 and 1992 in four provinces in The Netherlands who were born to mothers with epilepsy and using antiepileptic drugs during the first trimester of pregnancy, and 2,000 nonepileptic matched controls. We found significantly increased risks of major congenital abnormalities for carbamazepine and valproate monotherapy, with evidence for a significant dose-response relationship for valproate. The risk of major congenital abnormalities was nonsignificantly increased for phenobarbital monotherapy when caffeine comedication was excluded, but a significant increase in risk was found when caffeine was included. Phenytoin monotherapy was not associated with an increased risk of major congenital abnormalities. Regarding polytherapy regimens, increased risks were found for several antiepileptic drug combinations. Clonazepam, in combination with other antiepileptic drugs, showed a significantly increased relative risk. Furthermore, there were significantly increased relative risks for the combination of carbamazepine and valproate and the combination of phenobarbital and caffeine with other antiepileptic drugs. This study shows that most antiepileptic drug regimens were associated with an increased risk of major congenital abnormalities in the offspring, in particular valproate (dose-response relationship) and carbamazepine monotherapy, benzodiazepines in polytherapy, and caffeine comedication in combinations with phenobarbital.

    Full Text Available Background: Many adolescents with sickle cell disease (SCD have adjustment difficulties in the transition period from paediatric care to the adult system because they find themselves in unfamiliar waters where they have to learn to manage themselves. The aim of this study is to evaluate the prevalent crises and morbidities associated with SCD in adolescents in Babcock University Teaching Hospital (BUTH, to also assess the level of knowledge of these adolescents about SCD and to determine their emotional response to the disease. Materials and Methods: This was a retrospective review of case notes of adolescents with sickle cell anaemia that were seen in BUTH, from May 2013 to April 2014. Data extracted from the case notes was entered into a Microsoft (MS Excel and analysed using descriptive statistics. Results were presented in tables. Results: A total of 50 subjects were seen in the department during this study period. Vaso-occlusive crises in the form of bone pains (93.1% were the commonest crises encountered. Associated morbidities were malaria 34 (85%, tonsilitis 1 (2.5%, pneumonia 1 (2.5%, leg ulcer 1 (2.5%, azotaemia 1 (2.5% and subarachnoid haemorrhage 2 (5%. Majority (88% had adequate knowledge about general health maintenance while knowledge on nutrition and appropriate analgesia use is still inadequate. Eleven (22% had symptoms of depression, four (8% had suicidal ideation while one (2% had a history of attempted suicide. Conclusion: This study emphasizes the importance of psychosocial intervention as part of a comprehensive health management for people with SCD.

    Full Text Available Several attempts have been made previously to differentiate β-thalassaemia trait (BTT from other microcytic anaemias using formulae with red cell (RC parameters. Presently available formulae have low sensitivity and specificity. We wanted to develop a more precise algorithm, which could be used in situations where the gold-standard test for thalassaemia diagnosis: the high performance liquid chromatography (HPLC is not available. The study was carried out prospectively from November 2008 to March 2010 from randomly collected blood samples with a mean cell volume (MCV of less than 80 fL. HbA2 measured by HPLC was used to diagnose BTT. We used Fishers stepwise linear discriminant function analysis to develop an algorithm with RC parameters. Calculated new index Thal-index was then subjected to receiver operating characteristic curve analysis to identify best cutoff to discriminate BTT from other microcytic blood films. Software was developed to predict the BTT status (BTT prediction.exe. New index, referred to as the Thal-index, was calculated using discriminant function analysis and is given as Thal-index=[(0.615xMCV +(0.518xmean corpuscular hemoglobin+ (0.446xred cell distribution width]. A value of 59 for Thal-index has 90% sensitivity and 85% specificity for differentiating BTT from other microcytic anaemias. This showed better sensitivity and specificity compared to other formulae presently used (i.e., Mentzer in Eshani, et al.. Our study gives a better answer to set-up where HPLC is not available. Although this cannot replace HPLC, BTT prediction.exe is useful to predict instantly and is the first ever computer program available for this function. 先前已利用含红细胞(RC)参数的公式做出若干尝试,以鉴别β-地中海贫血(BTT)和其他小红细胞性贫血。目前可用公式的敏感度和特异度均低。我们想要开发更精确的算法,在地中海贫血诊断的金标准测试法(即高效液相色

    Full Text Available Objectives: The aim of this study was to establish the relationship between background amplitude and interictal abnormalities in routine electroencephalography (EEG. Methods: This retrospective audit was conducted between July 2006 and December 2009 at the Department of Clinical Physiology at Sultan Qaboos University Hospital (SQUH in Muscat, Oman. A total of 1,718 electroencephalograms (EEGs were reviewed. All EEGs were from patients who had been referred due to epilepsy, syncope or headaches. EEGs were divided into four groups based on their amplitude: group one ≤20 μV; group two 21–35 μV; group three 36–50 μV, and group four >50 μV. Interictal abnormalities were defined as epileptiform discharges with or without associated slow waves. Abnormalities were identified during periods of resting, hyperventilation and photic stimulation in each group. Results: The mean age ± standard deviation of the patients was 27 ± 12.5 years. Of the 1,718 EEGs, 542 (31.5% were abnormal. Interictal abnormalities increased with amplitude in all four categories and demonstrated a significant association (P <0.05. A total of 56 EEGs (3.3% had amplitudes that were ≤20 μV and none of these showed interictal epileptiform abnormalities. Conclusion: EEG amplitude is an important factor in determining the presence of interictal epileptiform abnormalities in routine EEGs. This should be taken into account when investigating patients for epilepsy. A strong argument is made for considering long-term EEG monitoring in order to identify unexplained seizures which may be secondary to epilepsy. It is recommended that all tertiary institutions provide EEG telemetry services.

    Full Text Available Introduction: There is a risk of anaemia among HIV-infected children on antiretroviral therapy (ART containing zidovudine (ZDV recommended in first-line regimens in the WHO guidelines. We estimated the risk of severe anaemia after initiation of a ZDV-containing regimen in HIV-infected children included in the IeDEA West African database. Methods: Standardized collection of data from HIV-infected children (positive PCR<18 months or positive serology ≥18 months followed up in HIV programmes was included in the regional IeDEA West Africa collaboration. Ten clinical centres from seven countries contributed (Benin, Burkina Faso, Côte d'Ivoire, Gambia, Ghana, Mali and Senegal to this collection. Inclusion criteria were age <16 years and starting ART. We explored the data quality of haemoglobin documentation over time and the incidence and predictors of severe anaemia (Hb<7g/dL per 100 child-years of follow-up over the duration of first-line antiretroviral therapy. Results: As of December 2009, among the 2933 children included in the collaboration, 45% were girls, median age was five years; median CD4 cell percentage was 13%; median weight-for-age z-score was−2.7; and 1772 (60.4% had a first-line ZDV-containing regimen. At baseline, 70% of the children with a first-line ZDV-containing regimen had a haemoglobin measure available versus 76% in those not on ZDV (p≤0.01: the prevalence of severe anaemia was 3.0% (n=38 in the ZDV group versus 10.2% (n=89 in those without (p<0. 01. Over the first-line follow-up, 58.9% of the children had ≥1 measure of haemoglobin available in those exposed to ZDV versus 60.4% of those not (p=0.45. Severe anaemia occurred in 92 children with an incidence of 2.47 per 100 child-years of follow-up in those on a ZDV-containing regimen versus 4.25 in those not (p≤0.01. Adjusted for age at ART initiation and first-line regimen, a weight-for-age z-score ≤−3 was a strong predictor associated with a 5.59 times risk of

    We will study the epidemiologic, clinical, biological, therapeutic, prognostic characteristics and predictive factors of development of nephropathy in ankylosing spondylitis patients. We retrospectively reviewed the medical record of 32 cases with renal involvement among 212 cases of ankylosing spondylitis followed in our service during the period spread out between 1978 and 2006. The renal involvement occurred in all patients a mean of 12 years after the clinical onset of the rheumatic disease. Thirty-two patients presented one or more signs of renal involvement: microscopic hematuria in 22 patients, proteinuria in 23 patients, nephrotic syndrome in 11 patients and decreased renal function in 24 patients (75%). Secondary renal amyloidosis (13 patients), which corresponds to a prevalence of 6,1% and tubulointerstitial nephropathy (7 patients) were the most common cause of renal involvement in ankylosing spondylitis followed by IgA nephropathy (4 patients). Seventeen patients evolved to the end stage renal disease after an average time of 29.8 ± 46 months. The average follow-up of the patients was 4,4 years. By comparing the 32 patients presenting a SPA and renal disease to 88 with SPA and without nephropathy, we detected the predictive factors of occurred of nephropathy: tobacco, intense inflammatory syndrome, sacroileite stage 3 or 4 and presence of column bamboo. The finding of 75% of the patients presented a renal failure at the time of the diagnosis of renal involvement suggests that evidence of renal abnormality involvement should be actively sought in this disease.

    Pearson marrow-pancreas syndrome is a multisystem mitochondrial disorder characterized by bone marrow failure and pancreatic insufficiency. Children who survive the severe bone marrow dysfunction in childhood develop Kearns-Sayre syndrome later in life. Here we report on four new cases with this condition and define their biochemical abnormalities. Three out of four patients presented with failure to thrive, with most of them having normal development and head size. All patients had evidence of bone marrow involvement that spontaneously improved in three out of four patients. Unique findings in our patients were acute pancreatitis (one out of four), renal Fanconi syndrome (present in all patients, but symptomatic only in one), and an unusual organic aciduria with 3-hydroxyisobutyric aciduria in one patient. Biochemical analysis indicated low levels of plasma citrulline and arginine, despite low-normal ammonia levels. Regression analysis indicated a significant correlation between each intermediate of the urea cycle and the next, except between ornithine and citrulline. This suggested that the reaction catalyzed by ornithine transcarbamylase (that converts ornithine to citrulline) might not be very efficient in patients with Pearson syndrome. In view of low-normal ammonia levels, we hypothesize that ammonia and carbamylphosphate could be diverted from the urea cycle to the synthesis of nucleotides in patients with Pearson syndrome and possibly other mitochondrial disorders.

    Full Text Available In this study, 44 patients with liver cirrhosis were investigated for hemostatic parameters. Patients with spontaneous bacterial peritonitis, hepatocellular carcinoma, hepatorenal syndrome and cholestatic liver diseases were excluded. Patients were classified by Child-Pugh criterion and according to this 4 patients were in Class A, 20 in Class B and 20 in C. Regarding to these results, it was aimed to investigate the haematological disturbances in liver cirrhotic patients.In the result there was a correlation between activated partial thromboplastin time, serum iron, ferritin, transferrin, haptoglobin and Child-Pugh classification. Besides there was no correlation between prothrombin time, factor 8 and 9, protein C and S, anti-thrombin 3, fibrinogen, fibrin degradation products, serum iron binding capacity, hemoglobin, leukocyte, mean corpuscular volume and Child-Pugh classification.There were significant difference, in terms of AST, ferritin, haptoglobulin, sex and presence of ascites between groups (p0.05. In the summary, we have found correlation between hemostatic abnormalities and disease activity and clinical prognosis in patients with liver cirrhosis which is important in the management of these patients. This is also important for identification of liver transplant candidiates earlier.

    Objective. To illustrate the variety of paravertebral muscle abnormalities as seen on computed tomography (CT) or magnetic resonance imaging (MRI) in association with spinal osteoblastomas and correlate the findings with the presence of scoliosis. Design. In a retrospective study the clinical notes, plain radiographic, CT and/or MRI features were reviewed for the presence of scoliosis and paravertebral muscle abnormality (either inflammation or atrophy). Patients. Twelve patients (7 male, 5 female) with a mean age of 17 years were studied. Three lesions occurred in the cervical spine, five in the thoracic spine and four in the lumbar spine. Results and conclusions. Nine patients had scoliosis. All patients with a thoracic or lumbar lesion and scoliosis (n=8) had an associated abnormality of the paravertebral muscles (usually atrophy with fatty replacement). One patient with a lumbar lesion and no scoliosis had normal paravertebral muscles. One patient with a cervical lesion had thoracic scoliosis but no muscle abnormality in the cervical region, while two patients with cervical lesions and no scoliosis showed muscle abnormalities. The results support the clinical hypothesis that scoliosis in patients with spinal osteoblastoma is due to paravertebral muscle spasm, although this would not appear to be the case for cervical lesions.

    2005-04-05

    Paternally transmitted chromosomal damage has been associated with pregnancy loss, developmental and morphological defects, infant mortality, infertility, and genetic diseases in the offspring including cancer. There is epidemiological evidence linking paternal exposure to occupational or environmental agents with an increased risk of abnormal reproductive outcomes. There is also a large body of literature on germ cell mutagenesis in rodents showing that treatment of male germ cells with mutagens has dramatic consequences on reproduction producing effects such as those observed in human epidemiological studies. However, we know very little about the etiology, transmission and early embryonic consequences of paternally-derived chromosomal abnormalities. The available evidence suggests that: (1) there are distinct patterns of germ cell-stage differences in the sensitivity of induction of transmissible genetic damage with male postmeiotic cells being the most sensitive; (2) cytogenetic abnormalities at first metaphase after fertilization are critical intermediates between paternal exposure and abnormal reproductive outcomes; and, (3) there are maternally susceptibility factors that may have profound effects on the amount of sperm DNA damage that is converted into chromosomal aberrations in the zygote and directly affect the risk for abnormal reproductive outcomes.

    Abnormal uterine bleeding is a common presenting complaint in gyanecology out patient department. Histopathological evaluation of the endometrial samples plays a significant role in the diagnosis of abnormal uterine bleeding. This study was carried out to determine the histopathological pattern of the endometrium in women of various age groups presenting with abnormal uterine bleeding. Endometrial biopsies and curettings of patients presenting with abnormal uterine bleeding was retrospectively studied. A total of 403 endometrial biopsies and curettings were analyzed. The age of the patients ranged from 18 to 70 years. Normal cyclical endometrium was seen in 165 (40.94%) cases, followed by 54 (13.40%) cases of disordered proliferative endometrium and 44 (10.92%) cases of hyperplasia. Malignancy was seen in 10 (2.48%) cases. Hyperplasia and malignancy were more common in the perimenopausal and postmenopausal age groups. Histopathological examination of endometrial biopsies and curettings in patients presenting with abnormal uterine bleeding showed a wide spectrum of changes ranging from normal endometrium to malignancy. Endometrial evaluation is specially recommended in women of perimenopausal and postmenopausal age groups presenting with AUB, to rule out a possibility of any preneoplastic condition or malignancy.

    Typhoon Maggie (1999) interacted with another tropical depression system and moved along a west-southwest track that is somewhat abnormal during its pre-landing stage. Two numerical experiments are carried out in this paper to study the effect of the interaction on the track of typhoon Maggie using the mesoscale numerical weather prediction model system with a tropical cyclone bogusing scheme developed by Center for Coastal and Atmospheric Research, the Hong Kong University of Science and Technology. Results show that the cyclone system interacting with Maggie is the main factor for the abnormal track of Maggie.

    A motion trajectory is an intuitive representation form in time-space domain for a micromotion behavior of moving target. Trajectory analysis is an important approach to recognize abnormal behaviors of moving targets. Against the complexity of vehicle trajectories, this paper first proposed a trajectory pattern learning method based on dynamic time warping (DTW) and spectral clustering. It introduced the DTW distance to measure the distances between vehicle trajectories and determined the number of clusters automatically by a spectral clustering algorithm based on the distance matrix. Then, it clusters sample data points into different clusters. After the spatial patterns and direction patterns learned from the clusters, a recognition method for detecting vehicle abnormal behaviors based on mixed pattern matching was proposed. The experimental results show that the proposed technical scheme can recognize main types of traffic abnormal behaviors effectively and has good robustness. The real-world application verified its feasibility and the validity.

    Full Text Available In this paper, a novel algorithm is proposed to detect abnormal events in video streams. The algorithm is based on the histogram of the optical flow orientation descriptor and the classification method. The details of the histogram of the optical flow orientation descriptor are illustrated for describing movement information of the global video frame or foreground frame. By combining one-class support vector machine and kernel principal component analysis methods, the abnormal events in the current frame can be detected after a learning period characterizing normal behaviors. The difference abnormal detection results are analyzed and explained. The proposed detection method is tested on benchmark datasets, then the experimental results show the effectiveness of the algorithm.

    Abnormal formation pressures occur not only in marine strata but also in terrestrialsedimentary basins in China.It develops most in Tertiary,followed by Mesozoic and Palaeozoic.Residualpressure decreases with the age of strata.Abnormal pressure raainly results from imbalanced compaction andhydrocarbon generation,and depends on various geological conditions.The secondary cause is the uplift ofcrust at the late stage and the transformation of clay minerals.Practical data show that the abnormal forma-tion pressure provides the dynamic force and passages for the primary migration of oil-gas,and in reservoirs,itcan affect the distribution of flow potential,which controls the migration direction and the aocumulation placeof oil and gas.

    Full Text Available Aim of the Study: The aim of this study was to evaluate platelet enzyme activity in cases of leukemia. Materials and Methods: Platelet enzymes glucose-6-phosphate dehydrogenase (G6PD, pyruvate kinase (PK and hexokinase (HK were studied in 47 patients of acute and chronic leukemia patients, 16 patients with acute myeloid leukemia (AML(13 relapse, three in remission, 12 patients with acute lymphocytic leukemia (ALL (five in relapse, seven in remission, 19 patients with chronic myeloid leukemia (CML. Results: The platelet G6PD activity was significantly low in cases of AML, ALL and also in CML. G6PD activity was normalized during AML remission. G6PD activity, although persistently low during ALL remission, increased significantly to near-normal during remission (P < 0.05 as compared with relapse (P < 0.01. Platelet PK activity was high during AML relapse (P < 0.05, which was normalized during remission. Platelet HK however was found to be decreased during all remission (P < 0.05. There was a significant positive correlation between G6PD and PK in cases of AML (P < 0.001 but not in ALL and CML. G6PD activity did not correlate with HK activity in any of the leukemic groups. A significant positive correlation was however seen between PK and HK activity in cases of ALL remission (P < 0.01 and CML (P < 0.05. Conclusions: Both red cell and platelet enzymes were studied in 36 leukemic patients and there was no statistically significant correlation between red cell and platelet enzymes. Platelet enzyme defect in leukemias suggests the inherent abnormality in megakaryopoiesis and would explain the functional platelet defects in leukemias.

  10. Eye-head coordination abnormalities in schizophrenia.

    Simon Schwab

    Full Text Available BACKGROUND: Eye-movement abnormalities in schizophrenia are a well-established phenomenon that has been observed in many studies. In such studies, visual targets are usually presented in the center of the visual field, and the subject's head remains fixed. However, in every-day life, targets may also appear in the periphery. This study is among the first to investigate eye and head movements in schizophrenia by presenting targets in the periphery of the visual field. METHODOLOGY/PRINCIPAL FINDINGS: Two different visual recognition tasks, color recognition and Landolt orientation tasks, were presented at the periphery (at a visual angle of 55° from the center of the field of view. Each subject viewed 96 trials, and all eye and head movements were simultaneously recorded using video-based oculography and magnetic motion tracking of the head. Data from 14 patients with schizophrenia and 14 controls were considered. The patients had similar saccadic latencies in both tasks, whereas controls had shorter saccadic latencies in the Landolt task. Patients performed more head movements, and had increased eye-head offsets during combined eye-head shifts than controls. CONCLUSIONS/SIGNIFICANCE: Patients with schizophrenia may not be able to adapt to the two different tasks to the same extent as controls, as seen by the former's task-specific saccadic latency pattern. This can be interpreted as a specific oculomotoric attentional dysfunction and may support the hypothesis that schizophrenia patients have difficulties determining the relevance of stimuli. Patients may also show an uneconomic over-performance of head-movements, which is possibly caused by alterations in frontal executive function that impair the inhibition of head shifts. In addition, a model was created explaining 93% of the variance of the response times as a function of eye and head amplitude, which was only observed in the controls, indicating abnormal eye-head coordination in patients

Results A total 406 specimens were referred to laboratory, ten abortuses were excluded, and in 14 cases, we did not get any spontaneous metaphase, chromosomal constitutions of 382 specimens were successfully obtained with conventional cytogenetic methods. Overall, 52.62% of the miscarriages were found to be cytogenetically abnormal among all patients, the frequency was 48.4% in the control group, 54.3% of miscarriages after ICSI and 55.3% after conventional IVF (p = 0.503. The most prevalent abnormalities were autosomal trisomy, however, nine (11.69% sex chromosome aneuploidy were noted in the ICSI group vs. four (6.45% and two (3.23% cases in the conventional IVF group and control group. We compared chromosomal abnormalities of miscarriages after ICSI according to infertility factor. 55.71% underwent ICSI due to male factors, 44.29% due to non-male factors. ICSI group having male factors showed significantly higher risk of chromosomal abnormalities than ICSI group having non-male factors (65.8% vs. 34.2%, p = 0.009, odds ratio = 1.529, 95% CI = 1

    Full Text Available Abstract Background Severe anaemia can develop in the aftermath of Plasmodium falciparum malaria because of protracted bone marrow suppression, possibly due to residual subpatent parasites. Materials and methods Blood was collected from patients with recent malaria and negative malaria microscopy. Detection of the Plasmodium antigens, lactate dehydrogenase (Optimal®, aldolase and histidine rich protein 2 (Now malaria® were used to differentiate between patients with (1 no malaria, (2 recent cleared malaria, (3 persistent P. falciparum infection. Red cell distribution width (RDW, plasma levels of soluble transferrin receptor (sTfR and erythropoietin (EPO were measured as markers of erythropoiesis. Interleukin (IL 10 and tumour necrosis factor (TNFα were used as inflammation markers. Results EPO was correlated with haemoglobin, irrespective of malaria (R = -0.36, P P. falciparum infection, but not recent malaria without residual parasites, was associated with bone marrow suppression i.e., low RDW (P Conclusion In the treatment of malaria, complete eradication of parasites may prevent subsequent development of anaemia. Severely anaemic children may benefit from antimalarial treatment if antigen tests are positive, even when no parasites can be demonstrated by microscopy.

    Megaloblastic anaemia 1 (MGA1, OMIM 261100) is a rare, autosomal recessive disorder characterized by juvenile megaloblastic anaemia, as well as neurological symptoms that may be the only manifestations. At the cellular level, MGA1 is characterized by selective intestinal vitamin B12 (B12, cobalamin) malabsorption. MGA1 occurs worldwide, but its prevalence is higher in several Middle Eastern countries and Norway, and highest in Finland (0.8/100,000). We previously mapped the MGA1 locus by linkage analysis in Finnish and Norwegian families to a 6-cM region on chromosome 10p12.1 (ref. 8). A functional candidate gene encoding the intrinsic factor (IF)-B12 receptor, cubilin, was recently cloned; the human homologue, CUBN, was mapped to the same region. We have now refined the MGA1 region by linkage disequilibrium (LD) mapping, fine-mapped CUBN and identified two independent disease-specific CUBN mutations in 17 Finnish MGA1 families. Our genetic and molecular data indicate that mutations in CUBN cause MGA1.

    2009-01-01

    Myopathy, lactic acidosis and sideroblastic anaemia (MLASA) is a rare condition that combines early-onset myopathy with lactic acidosis and sideroblastic anaemia. MLASA has been associated with a missense mutation in pseudouridylate synthase 1 (PUS1), an enzyme located in both nucleus and mitochondria, which converts uridine into pseudouridine in several cytosolic and mitochondrial tRNA positions and increases the efficiency of protein synthesis in both compartments. We examined two Italian brothers with MLSA and sequenced the PUS1 gene. We found combined defects in mitochondrial respiratory chain complexes in muscle and fibroblast homogenates of both patients, and low levels of mtDNA translation products in fibroblast mitochondria. A novel, homozygous stop mutation was present in PUS1 (E220X). The stop mutation in PUS1 is likely to determine the loss of function of the protein, since it predicts the synthesis of a protein missing 208/427 amino acid residues on the C terminus, and was associated with low mtDNA translation.

    In the last 9 years, epizootics of an icterus condition has affected coho salmon, Oncorhynchus kisutch (Walbaum), reared in seawater cages in southern regions of Chile. At necropsy, fish from field cases exhibited signs of jaundice accompanied by pale light-brown livers and dark spleens. Histopathological and haematological results indicated that these fish presented haemolytic anaemia. After microbiological examination no bacterial or viral agents could be identified as aetiological agents of this disease. In an infectivity trial, coho salmon, Atlantic salmon, Salmo salar L., and rainbow trout, Oncorhynchus mykiss (Walbaum), were inoculated intraperitoneally with a filtrate of an organ homogenate (0.45 microm) from a diseased coho salmon and held for 60 days in tanks supplied with fresh water. The disease was only reproduced in coho salmon in which mortalities, beginning at day 23 post-inoculation (p.i.), reached a cumulative value of 24% at day 27 p.i. This condition was transmitted to non-inoculated cohabiting coho salmon suggesting that it is a waterborne disease. Thus, this icteric condition is caused by an infectious form of haemolytic anaemia, probably of viral aetiology, and coho salmon are more susceptible than either Atlantic salmon or rainbow trout.

    Background Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. Objective We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. Methods This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Results Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (p<0.001). Conclusions Nail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study. PMID:27579738

    2015-05-14

    A woman in her late 40s presented with excessive per vagina (PV) bleeding and uterine fibroid. She reported excessive PV bleeding after starting Esmya; she was brought in by ambulance to the emergency department with profuse bleeding. Abnormal uterine bleeding (AUB) developed after selective progesterone receptor modulator (SPRM) administration in this symptomatic patient with uterine fibroid. The drug was withheld and surgical treatment considered. Progressive deterioration of PV bleeding after receiving SPRM led to an urgent laparoscopic total hysterectomy, which had to be postponed due to severe anaemia. Surgery took place regardless because the excessive bleeding continued. Histology revealed a 6 cm submucosal uterine fibroid (SMUF) and adenomyosis. Physicians prescribing SPRMs to stop PV bleeding should be aware of potential AUB, which could lead to urgent hysterectomy. The mechanism of action of SPRMs is not clearly understood. Awareness of the side effects of Esmya, such as AUB, must be kept in mind when administering SPRMs.

    Taking Baidu Index as a proxy for abnormal investor attention (AIA), the long memory property in the AIA of Shanghai Stock Exchange (SSE) 50 Index component stocks was empirically investigated using detrended fluctuation analysis (DFA) method. The results show that abnormal investor attention is power-law correlated with Hurst exponents between 0.64 and 0.98. Furthermore, the cross-correlations between abnormal investor attention and trading volume, volatility respectively are studied using detrended cross-correlation analysis (DCCA) and the DCCA cross-correlation coefficient (ρDCCA). The results suggest that there are positive correlations between AIA and trading volume, volatility respectively. In addition, the correlations for trading volume are in general higher than the ones for volatility. By carrying on rescaled range analysis (R/S) and rolling windows analysis, we find that the results mentioned above are effective and significant.

    This is a single centre experience on the use of immunosuppressive therapy (IST) and stem cell transplantation (SCT) in patients with aplastic anaemia. Between 1985 and December 2013, 530 patients underwent IST while 214 underwent allogeneic SCT. Overall response rate with the use of IST was 58% with higher responses seen in adults (65.1%) compared to children (35.8%) [p = 0.001]. At a median follow up of 34 months (range: 1 - 264), 5 year KM estimates for OS for the entire group is 68.2 ± 2.2%. Loss of response or relapse was seen in 27 responders while clonal evolution to PNH was seen in 8 patients and transformation to MDS or AML was seen in 3. The 5 yr OS for children (45.7 ± 4.7%) was significantly lower than the OS of age groups 16-30 (75.6 ± 3.6%), 31-50 years (76.2 ± 4.2%) and > 50 years (73.0 ±4.2%) (p = 0.0001). SCT was performed in 214 patients with engraftment seen in 91%. The incidence of grade II-IV acute graft versus host disease (GVHD) was 38.4% with grade III-IV GVHD in 11.7%. Chronic GVHD was seen in 47.5% of evaluable patients with majority (73%) being limited chronic GVHD. At a median follow up of 32 months (range: 1 - 244), the 5 year KM estimates of OS for the entire cohort is 64.8 ± 3.3%); The 5 yr OS was significantly higher with the use of Flu/Cy (5 yr OS of 73.8 ± 3.6%) compared to Cy/ATG (5 yr OS of 44.4 ± 9.6%) or Flu/Bu conditioning (5 yr OS of 52.4 ± 8.9%) [p = 0.001]. Imp: SCT and IST offer good response rates and survival in Indian patients with AA except in children receiving IST.

  3. Chromosomal abnormalities in patients with sperm disorders

    Full Text Available Chromosomal abnormalities are among the most common genetic causes of spermatogenic disruptions. Carriers of chromosomal abnormalities are at increased risk of infertility, miscarriage or birth of a child with unbalanced karyotype due to the production of unbalanced gametes. The natural selection against chromosomally abnormal sperm usually prevents fertilization with sperm barring in cases of serious chromosomal abnormalities. However, assisted reproductive technologies in general and intracytoplasmic sperm injection in particular, enable the transmission of chromosomal abnormalities to the progeny. Therefore, cytogenetic studies are important in patients with male factor infertility before assisted reproduction treatment. The purpose of the current study was to investigate the types and frequencies of chromosomal abnormalities in 724 patients with infertility and to estimate the risk of chromosomal abnormalities detection in subgroups of patients depending on the severity of spermatogenic disruption, aiming at identifying groups of patients in need of cytogenetic studies. Karyotype analysis was performed in 724 blood samples of men attending infertility clinic. Chromosomal preparation was performed by standard techniques. At least 20 GTG-banded metaphase plates with the resolution from 450 to 750 bands per haploid set were analysed in each case. When chromosomal mosaicism was suspected, this number was increased to 50. Abnormal karyotypes were observed in 48 (6.6% patients, including 67% of autosomal abnormalities and 33% of gonosomal abnormalities. Autosomal abnormalities were represented by structural rearrangements. Reciprocal translocations were the most common type of structural chromosomal abnormalities in the studied group, detected with the frequency of 2.6% (n = 19, followed by Robertsonian translocation, observed with the frequency of 1.2% (n = 9. The frequency of inversions was 0.6% (n = 4. Gonosomal abnormalities included 14 cases

    Full Text Available A 38-day-old male warthog (Phacochoerus aethiopicus with marked anaemia (haematocrit = 14 % presented to the Denver Zoological Gardens hospital with ataxia, tachypnoea, suspected stunted growth and cardiomegaly. The piglet demonstrated some features consistent with both iron deficiency anaemia and autoimmune haemolytic anaemia. Serum-soluble iron was below the level of detection (<8.96 mmol/l. Iron deficiency anaemia is a well recognised entity in domestic swine reared on concrete and denied access to soil. Fifteen captive warthogs were subsequently evaluated for serum soluble iron content (mean = 21.62±4.36 mmol/l as well as 5 neonatal warthog piglets that required hand-rearing. Only 1 of 5 neonatal warthog piglets had measurable serum soluble iron (9.50 mmol/l. These data suggest that warthogs are similar to domestic swine and are born with low iron stores. Some form of iron supplementation should be considered for captive neonatal warthog piglets, especially if they are reared on concrete.

Interleukin 12 (IL12 significantly boosts erythropoietic responses in murine models of malarial anaemia and decreased IL12 levels are associated with severe malarial anaemia (SMA in children. Based on the biological relevance of IL12 in malaria anaemia, the relationship between genetic polymorphisms of IL12 and its receptors and SMA was examined. Methods Fifty-five tagging single nucleotide polymorphisms covering genes encoding two IL12 subunits, IL12A and IL12B, and its receptors, IL12RB1 and IL12RB2, were examined in a cohort of 913 children residing in Asembo Bay region of western Kenya. Results An increasing copy number of minor variant (C in IL12A (rs2243140 was significantly associated with a decreased risk of SMA (P = 0.006; risk ratio, 0.52 for carrying one copy of allele C and 0.28 for two copies. Individuals possessing two copies of a rare variant (C in IL12RB1 (rs429774 also appeared to be strongly protective against SMA (P = 0.00005; risk ratio, 0.18. In addition, children homozygous for another rare allele (T in IL12A (rs22431348 were associated with reduced risk of severe anaemia (SA (P = 0.004; risk ratio, 0.69 and of severe anaemia with any parasitaemia (SAP (P = 0.004; risk ratio, 0.66. In contrast, AG genotype for another variant in IL12RB1 (rs383483 was associated with susceptibility to high-density parasitaemia (HDP (P = 0.003; risk ratio, 1.21. Conclusions This study has shown strong associations between polymorphisms in the genes of IL12A and IL12RB1 and protection from SMA in Kenyan children, suggesting that human genetic variants of IL12 related genes may significantly contribute to the development of anaemia in malaria patients.

    The presence of brain dysfunction in violent offenders has been frequently examined with inconsistent results. The aim of the study was to assess the EEG of 84 violent offenders by visual inspection and frequency-domain quantitative analysis in 84 violent prisoners. Low-resolution electromagnetic tomography (LORETA) was also employed for theta band of the EEG spectra. Antisocial personality disorder (ASPD) was present in 50 of the offenders and it was absent in the remaining 34. The prevalence of EEG abnormalities, by visual inspection, was similar for both the ASPD group (82%) and non-ASPD group (79%). The brain topography of these anomalies also did not differ between groups, in contrast to results of the EEG quantitative analysis (QEEG) and LORETA that showed remarkable regional differences between both groups. QEEG analysis showed a pattern of excess of theta-delta activities and decrease of alpha band on the right fronto-temporal and left temporo-parietal regions in the ASPD group. LORETA signified an increase of theta activity (5.08 Hz) in ASPD group relative to non-ASPD group within left temporal and parietal regions. Findings indicate that QEEG analysis and techniques of source localization may reveal differences in brain electrical activity among offenders with ASPD, which was not obvious to visual inspection.

    in several different sports. Data collected was by verification of anthropometric measures (body weight, height, and skinfold thicknesses of triceps and subscapular skinfold, hemoglobin dosage utilizing a portable hemoglobinometer, HemoCue direct calorimetric method, and socioeconomic instrument. In the diagnosis of the nutritional states, we used Height-for-age- and Body Mass Index for the age indicators, adjusted cut-off points proposed by the WHO. The results showed that 9.4 % of the adolescents suffered from malnutrition, 8.2% overweight, and 4.6 obesity. The prevalence of iron deficiency anaemia found in the samples was 41.7%, with predominance in the lowest socioeconomic class. Although the prevalence of anaemia was high, the nutritional state of the adolescents did not influence these results, considering that the majority looked healthy. In view of these findings, we suggest that effective means be taken for nutritional education to minimize and/or control iron deficiency anaemia.

    Rett syndrome (RTT) is a female neurodevelopmental disease with breathing abnormalities. To understand whether breathing defects occur in the early lives of a group of female Mecp2(+/-) mice, a mouse model of RTT, and what percentage of mice shows RTT-like breathing abnormality, breathing activity was measured by plethysmography in conscious mice. Breathing frequency variation and central apnea in a group of Mecp2(+/-) females displayed a distribution pattern similar to Mecp2(-/Y) males, while the rest resembled the wild-type mice. Similar results were obtained using the k-mean clustering statistics analysis. With two independent methods, about 20% of female Mecp2(+/-) mice showed RTT-like breathing abnormalities that began as early as 3 weeks of age in the Mecp2(+/-) mice, and were suppressed with 3% CO2. The finding that only a small proportion of Mecp2(+/-) mice develops RTT-like breathing abnormalities suggests incomplete allele inactivation in the RTT-model Mecp2(+/-) mice.

    Indications and candidates for preimplantation genetic diagnosis (PGD) have increased in recent years. This study evaluates whether IVF-intracytoplasmic sperm injection (ICSI) results could be improved by selecting embryos through PGD-AS (aneuploidy screening) in couples in whom the male partner presents meiotic abnormalities. Two hundred and fifty-six embryos were biopsied and 183 were suitable for analysis (73.2%). Ninety-two embryos showed normal chromosomal analysis (50.3% of the analysed embryos and 57.5% of the diagnosed embryos). Pregnancy, abortion and implantation rates were compared with 66 IVF-ICSI cycles performed in 44 patients with meiotic abnormalities without PGD (control group). No statistically significant differences in the pregnancy rate (52 versus 43.9%), implantation rate (32.1 versus 23.5%) and miscarriage rate (15.4 versus 10.3%) were observed between the groups. Although the embryos obtained from men with meiotic abnormalities showed a high frequency of chromosome abnormalities, no improvements in pregnancy and implantation rates were obtained after PGD-AS in the series analysed.

    Full Text Available Abstract Background Hematological abnormalities are a common complication of HIV infection. These abnormalities increase as the disease advances. Bone marrow abnormalities occur in all stages of HIV infection. Methods Two hundred HIV infected individual were screened for hematological abnormalities from March 2007–March 2008. Absolute CD4 cell count analysis was carried out by flowcytometry. Depending on the results of the primary screening further investigations were performed, like iron studies, hemolytic work up, PNH work up and bone marrow evaluation. Other investigations included coagulation profile, urine analysis, blood culture (bacterial, fungal, mycobacterial, serology for Epstein Barr virus (EBV, Cytomegalovirus (CMV, Hepatitis B and C, and Parvo B19 infection. Results The most common hematological abnormality was anemia, seen in 65.5% (131/200 patients. Iron deficiency anemia was seen in 49.2% (/200 cases while anemia of chronic disease occurred in 50.7% (/200 cases. Bone marrow evaluation was carried out in 14 patients out of which staging marrow was performed in 2 cases of non-Hodgkin's lymphoma (NHL and did not show any bone marrow infiltration. In remaining12 cases bone marrow was done for evaluation of pancytopenia. Among patients with pancytopenia 50% (6/12 showed granulomas (4 were positive for AFB, 2 were positive for fungal cryptococci, 25% (3/12 showed hemophagocytosis. There was a strong negative correlation between anemia and CD4 counts in this study. Thrombocytopenia was seen in 7% (14/200 cases and had no significant correlation with CD4 counts. No patient had absolute neutrophil count (ANC Conclusion Anemia in HIV patients can be a good clinical indicator to predict and access the underlying immune status. Patients should be investigated for hematological manifestations and appropriate steps should be taken to identify and treat the reversible factors.

    Abnormalities in cortical structure are commonly observed in children with dyslexia in key regions of the "reading network." Whether alteration in cortical features reflects pathology inherent to dyslexia or environmental influence (e.g., impoverished reading experience) remains unclear. To address this question, we compared MRI-derived metrics of cortical thickness (CT), surface area (SA), gray matter volume (GMV), and their lateralization across three different groups of children with a historical diagnosis of dyslexia, who varied in current reading level. We compared three dyslexia subgroups with: (1) persistent reading and spelling impairment; (2) remediated reading impairment (normal reading scores), and (3) remediated reading and spelling impairments (normal reading and spelling scores); and a control group of (4) typically developing children. All groups were matched for age, gender, handedness, and IQ. We hypothesized that the dyslexia group would show cortical abnormalities in regions of the reading network relative to controls, irrespective of remediation status. Such a finding would support that cortical abnormalities are inherent to dyslexia and are not a consequence of abnormal reading experience. Results revealed increased CT of the left fusiform gyrus in the dyslexia group relative to controls. Similarly, the dyslexia group showed CT increase of the right superior temporal gyrus, extending into the planum temporale, which resulted in a rightward CT asymmetry on lateralization indices. There were no group differences in SA, GMV, or their lateralization. These findings held true regardless of remediation status. Each reading level group showed the same "double hit" of atypically increased left fusiform CT and rightward superior temporal CT asymmetry. Thus, findings provide evidence that a developmental history of dyslexia is associated with CT abnormalities, independent of remediation status.

    Bowel rotation abnormalities in heterotaxy are common. As more children survive cardiac surgery, the management of gastrointestinal abnormalities has become controversial. To evaluate imaging of malrotation in heterotaxy with surgical correlation and provide an algorithm for management. Imaging reports of heterotaxic children with upper gastrointestinal (UGI) and/or small bowel follow-through (SBFT) were reviewed. Subsequently, fluoroscopic images were re-reviewed in conjunction with CT/MR studies. The original reports and re-reviewed images were compared and correlated with surgical findings. Nineteen of 34 children with heterotaxy underwent UGI, 13/19 also had SBFT. In 15/19 reports, bowel rotation was called abnormal: 11 malrotation, 4 non-rotation, no cases of volvulus. Re-review, including CT (10/19) and MR (2/19), designated 17/19 (90%) as abnormal, 10 malrotation (abnormal bowel arrangement, narrow or uncertain length of mesentery) and 7 non-rotation (small bowel and colon on opposite sides plus low cecum with probable broad mesentery). The most useful CT/MR findings were absence of retroperitoneal duodenum in most abnormal cases and location of bowel, especially cecum. Abnormal orientation of mesenteric vessels suggested malrotation but was not universal. Nine children had elective bowel surgery; non-rotation was found in 4/9 and malrotation was found in 5/9, with discrepancies (non-rotation at surgery, malrotation on imaging) with 4 original interpretations and 1 re-review. We recommend routine, early UGI and SBFT studies once other, urgent clinical concerns have been stabilized, with elective laparoscopic surgery in abnormal or equivocal cases. Cross-sectional imaging, usually obtained for other reasons, can contribute diagnostically. Attempting to assess mesenteric width is important in differentiating non-rotation from malrotation and more accurately identifies appropriate surgical candidates. (orig.)

    Full Text Available To determine the prevalence of asymptomatic urinary abnormalities in adolescents, first morning clean mid-stream urine specimens were obtained from 2500 individuals and examined by dipstick and light microscopy. Adolescents with abnormal screening results were reexamined after two weeks and those who had abnormal results twice were subjected to systemic clinical examination and further clinical and laboratory investigations. Eight hundred and three (32.1% individuals had urinary abnormalities at the first screening, which significantly decreased to 345 (13.8% at the second screening, (P <0.001. Hematuria was the most common urinary abnormalities detected in 245 (9.8% adolescents who had persistent urine abnormalities; 228 (9.1% individuals had non glomerular hematuria. The hematuria was isolated in 150 (6% individuals, combined with leukocyturia in 83 (3.3% individuals, and combined with proteinuria in 12 (0.5% individuals. Leukocyturia was detected in 150 (6% of all studied adolescents; it was isolated in 39 (1.6% individuals and combined with proteinuria in 28 (1.1% of them. Asymp- tomatic bacteriuria was detected in 23 (0.9% of all studied adolescents; all the cases were females. Proteinuria was detected in 65 (2.6% of all the studied adolescents; 45 (1.8% indivi- duals had <0.5 g/day and twenty (0.8% individuals had 0.5-3 g/day. Asymptomatic urinary abnormalities were more common in males than females and adolescents from rural than urban areas (P <0.01 and (P <0.001, respectively. The present study found a high prevalence of asymptomatic urinary abnormalities among adolescents in our population.

    Diabetic macular ischemia (DMI) is a phenotype of diabetic retinopathy (DR) associated with chronic hypoxia of retinal tissue. The goal of this prospective observational study was to report evidence of photoreceptor abnormalities using adaptive optics scanning laser ophthalmoscopy (AOSLO) in eyes with DR in the setting of deep capillary plexus (DCP) non-perfusion. Eleven eyes from 11 patients (6 women, age 31–68), diagnosed with DR without macular edema, underwent optical coherence tomography angiography (OCTA) and AOSLO imaging. One patient without OCTA imaging underwent fluorescein angiography to characterize the enlargement of the foveal avascular zone. The parameters studied included photoreceptor heterogeneity packing index (HPi) on AOSLO, as well as DCP non-perfusion and vessel density on OCTA. Using AOSLO, OCTA and spectral domain (SD)-OCT, we observed that photoreceptor abnormalities on AOSLO and SD-OCT were found in eyes with non-perfusion of the DCP on OCTA. All eight eyes with DCP non-flow on OCTA showed photoreceptor abnormalities on AOSLO. Six of the eight eyes also had outer retinal abnormalities on SD-OCT. Three eyes with DR and robust capillary perfusion of the DCP had normal photoreceptors on SD-OCT and AOSLO. Compared to eyes with DR without DCP non-flow, the eight eyes with DCP non-flow had significantly lower HPi (P = 0.013) and parafoveal DCP vessel density (P = 0.016). We found a significant correlation between cone HPi and parafoveal DCP vessel density (r = 0.681, P = 0.030). Using a novel approach with AOSLO and OCTA, this study shows an association between capillary non-perfusion of the DCP and abnormalities in the photoreceptor layer in eyes with DR. This observation is important in confirming the significant contribution of the DCP to oxygen requirements of photoreceptors in DMI, while highlighting the ability of AOSLO to detect subtle photoreceptor changes not always visible on SD-OCT.

    Full Text Available Background :The behavioral phenotype in Down syndrome follows a characteristic pattern. Aims: To find the incidence of behavioral abnormalities in Down syndrome, to compare these findings with other causes of intellectual disability and normal population and to cluster these abnormalities. Settings :One hundred forty mentally challenged people attending at tertiary care set up and from various non-governmental organizations were included in the study. Patients from both rural and urban set up participated in the study. The age-matched group from normal population was also studied for comparison. Design :The study design is a cross-sectional survey done independently by four observers. Materials and Methods :A semi-structured proforma for demographic profile has been used. The behavioral abnormalities are assessed by using DASH II (Diagnostic Assessment for the Severely Handicapped second modified version scale. Statistical Analysis :Demographic comparison has been done by analysis of variance. Correlation matrix has been run to identify correlation between individual items. Principal component analysis has been used for grouping the behavioral pattern. Results :Behavioral abnormalities as expected are more common in people having intellectual disability than the normal population. The Down syndrome group unlike other causes of intellectual disability shows higher scores in Stereotypy. Impulse control and Mania subscales. Factor analysis yields five characteristic factor structures, namely, hyperactive-impulsive, biological functions, affective, neurotic and organic-pervasive developmental disorder clusters. Conclusions :Contrary to the conventional belief of docile-fun and music loving prototype, individuals diagnosed with Down syndrome show clusters of behavioral abnormalities and management can vary depending on these target symptoms.

  16. Ultra-deep pyrosequencing of partial surface protein genes from infectious Salmon Anaemia virus (ISAV suggest novel mechanisms involved in transition to virulence.

    Turhan Markussen

    Full Text Available Uncultivable HPR0 strains of infectious salmon anaemia viruses (ISAVs infecting gills are non-virulent putative precursors of virulent ISAVs (vISAVs causing systemic disease in farmed Atlantic salmon (Salmo salar. The transition to virulence involves two molecular events, a deletion in the highly polymorphic region (HPR of the hemagglutinin-esterase (HE gene and a Q266→L266 substitution or insertion next to the putative cleavage site (R267 in the fusion protein (F. We have performed ultra-deep pyrosequencing (UDPS of these gene regions from healthy fish positive for HPR0 virus carrying full-length HPR sampled in a screening program, and a vISAV strain from an ISA outbreak at the same farming site three weeks later, and compared the mutant spectra. As the UDPS data shows the presence of both HE genotypes at both sampling times, and the outbreak strain was unlikely to be directly related to the HPR0 strain, this is the first report of a double infection with HPR0s and vISAVs. For F amplicon reads, mutation frequencies generating L266 codons in screening samples and Q266 codons in outbreak samples were not higher than at any random site. We suggest quasispecies heterogeneity as well as RNA structural properties are linked to transition to virulence. More specifically, a mechanism where selected single point mutations in the full-length HPR alter the RNA structure facilitating single- or sequential deletions in this region is proposed. The data provides stronger support for the deletion hypothesis, as opposed to recombination, as the responsible mechanism for generating the sequence deletions in HE.

    We report the observation of an abnormal carrier transport phenomenon in polycrystalline semiconducting graphene grown by solid carbon source molecular beam epitaxy. At the lowest temperatures in samples with small grain size, the conduction does not obey the two-dimensional Mott-type variable-range hopping (VRH) conduction often reported in semiconducting graphene. The hopping exponent p is found to deviate from the 1/3 value expected for Mott VRH with several samples exhibiting a p=2/5 dependence. We also show that the maximum energy difference between hopping sites is larger than the activation energy for nearest-neighbor hopping, violating the assumptions of the Mott model. The 2/5 dependence more closely agrees with the quasi-one-dimensional VRH model proposed by Fogler, Teber, and Shklovskii (FTS). In the FTS model, conduction occurs by tunneling between neighboring metallic wires. We suggest that metallic edge states and conductive grain boundaries play the role of the metallic wires in the FTS model.

  18. Abnormal parietal function in conversion paresis.

    Marije van Beilen

    Full Text Available The etiology of medically unexplained symptoms such as conversion disorder is poorly understood. This is partly because the interpretation of neuroimaging results in conversion paresis has been complicated by the use of different control groups, tasks and statistical comparisons. The present study includes these different aspects in a single data set. In our study we included both normal controls and feigners to control for conversion paresis. We studied both movement execution and imagery, and we contrasted both within-group and between-group activation. Moreover, to reveal hemisphere-specific effects that have not been reported before, we performed these analyses using both flipped and unflipped data. This approach resulted in the identification of abnormal parietal activation which was specific for conversion paresis patients. Patients also showed reduced activity in the prefrontal cortex, supramarginal gyrus and precuneus, including hemisphere-specific activation that is lateralized in the same hemisphere, regardless of right- or left-sided paresis. We propose that these regions are candidates for an interface between psychological mechanisms and disturbed higher-order motor control. Our study presents an integrative neurophysiological view of the mechanisms that contribute to the etiology of this puzzling psychological disorder, which can be further investigated with other types of conversion symptoms.

    Full Text Available Patients with psychosis display structural brain abnormalities in multiple brain regions. The disorder is characterized by a putative prodromal period called ultra-high-risk (UHR status, which precedes the onset of full-blown psychotic symptoms. Recent studies on psychosis have focused on this period. Neuroimaging studies of UHR individuals for psychosis have revealed that the structural brain changes observed during the established phases of the disorder are already evident prior to the onset of the illness. Moreover, certain brain regions show extremely dynamic changes during the transition to psychosis. These neurobiological features may be used as prognostic and predictive biomarkers for psychosis. With advances in neuroimaging techniques, neuroimaging studies focusing on gray matter abnormalities provide new insights into the pathophysiology of psychosis, as well as new treatment strategies. Some of these novel approaches involve antioxidants administration, because it is suggested that this treatment may delay the progression of UHR to a full-blown psychosis and prevent progressive structural changes. The present review includes an update on the most recent developments in early intervention strategies for psychosis and potential therapeutic treatments for schizophrenia. First, we provide the basic knowledge of the brain regions associated with structural abnormalities in individuals at UHR. Next, we discuss the feasibility on the use of magnetic resonance imaging (MRI-biomarkers in clinical practice. Then, we describe potential etiopathological mechanisms underlying structural brain abnormalities in prodromal psychosis. Finally, we discuss the potentials and limitations related to neuroimaging studies in individuals at UHR.

    Any kind of stress has a negative effect on the mood of people and stress resulting from war is no exception. Stress from war has not only has effects on war veterans but also on the families. Children of these families have been more susceptible to abnormal oral habits. In this observational, analytical and historical research, attempts have been made to determine the prevalence of abnormal oral habits in the children of war veterans (martyrs, freed prisoners of war and war cripples) and compare them with a control group. In this study of 520 children aged between 7 and 11 years were (238 in the study group and 282 in the control group), information was gathered via a questionnaire completed by the mothers of the students. Analysis of the received information showed that the prevalence of para functional and abnormal oral habits was more in the study group (P = 0.005). The prevalence rate was highest in children, whose family members had been both crippled and freed prisoners of war, while the rate was lowest in children whose parents had been only prisoners of war without any lasting physical injury. Most of these children had acquired these habits at the age of seven and these abnormal habits were most prevalent in children aged eight and nine.
