    Severe anaemia is a rare, unexplained, side effect of azathioprine therapy. We report here such a case associated with a previously unreported abnormality in azathioprine metabolism. A 57 year old man on azathioprine therapy, for a presumed collagen vascular disease, developed severe megaloblastic anaemia. This resolved on cessation of azathioprine treatment. A very high concentration of an azathioprine metabolite, 6-thioguanine nucleotide, was found in the patient's red blood cells and this ...

    Full Text Available BACKGROUND : Folate and vitamin12 deficiency have been known to cause megaloblastic anaemia. Megaloblastic anaemia is not uncommon in India , but data are insufficient regarding its prevalence , causative factors and precipitating factors. AIMS & OBJECTIVES : To evaluate the clinic o - haematological profile in patients of macrocytic anaemia. MATERIAL AND METHODS : In the present study , 50 patients of >20years of age with hemoglobin 95 fl and PBF showing macrocytosis and pancytopenia were included. Detailed history with clinical examination was performed and investigations (Bone Marrow aspiration , Serum Folate and cobalamin assays were carried out. RESULTS : The peak incidence of megaloblas tic anaemia was in the age group of 41 - 50 years (48% , with male preponderance (71% . ( The predominant symptoms were fatigue (54% followed by low grade fever (52% , breathlessness (50% , and mild jaundice (22% . ( Physicalfindingswere pallor (88 % , hepatomegaly (80% , knuckle hyperpigmentation (68% , glossitis (50% , peripheral neuropathy (28% and mild icterus was the least common finding in 22% of patients. 64% patients of macrocytic anaemia were found to be lactovegetarian. Cobalamin deficiency wa s present in maximum patients (50% , followed by combined cobalamin and folate deficiency in 34% and folate deficiency in 16% of patients. Bonemarrowsmears revealed megaloblastic picture in 58% of patients and 42% patients had non - megaloblastic bone marrow picture. C ONCLUSION : Megaloblastic anaemia must be considered in the differential diagnosis of patients presenting with pyrexia of unknown origin , mild ic terus or pancytopenia. Therefore , the early screening for cobalamin and folic acid deficiency can lead to improvement in the wellbeing and prolongs the life of people in our community.

    Direct destruction and ineffective erythropoesis does not adequately explain the cause of anaemia in malaria. It is possible that there are more other mechanisms involved besides the causes described till date in malarial anaemia. The effect of NO on erythropoesis and a major haematological abnormality (microcytic/normocytic/megaloblastic picture) can significantly be observed on repeated exposure. In addition, NO can inhibit the enzyme methionine synthase so functional vit B12 deficiency state may occur which can lead to megaloblastic anaemia. This review will focus on causation of malarial anaemia and nitric oxide induced megaloblastic anaemia. PMID:19502689

    We describe a 57-year-old patient with Turner's syndrome, iron deficiency anaemia and intestinal vascular abnormalities. Colonoscopy revealed 2 widely dilated, tortuous veins in the terminal ileum and several smaller ectatic veins and haemangioma-like malformations throughout the colon. Laparotomy for herniotomy showed only minimal vascular abnormalities of the serosal surface. Patients with Turner's syndrome and anaemia should be checked for these lesions by endoscopy, and conversely, in pat...

    The electron backscatter diffraction (EBSD) technique has been used to determine grain orientations of abnormally grown grains in nanocrystalline Ni electrodeposits upon annealing. The results show that the first grown grains have a <3 1 1>//ND orientation. Upon annealing further grain growth occurs and the preferred alignment of the abnormally growing grains changes from <3 1 1>//ND to <1 1 1>//ND. The subgrain coalescence model adopted from recrystallization is used to describe the occurrence of abnormal grain growth, and energy considerations are put forward for explaining the dominance of the <1 1 1>//ND texture component after longer annealing treatments.

  8. A case of linear nevus sebaceous syndrome showing abnormalities by head CT scan

    International Nuclear Information System (INIS)

    A female baby weighing 2,702 g, who was delivered spontaneously after 37 weeks of gestation, showed linear nevus sebaceous syndrome with abnormalities on EEG and head CT scan. Immediately after birth, the baby showed abnormalities of the skin in the left half of the body, especially from the head to the face. At the same time, EEG showed a low voltage on the affected side, and head CT scan showed expansion of the lateral ventricle. Funduscopic findings showed retinochoroidal toxoplasmosis-like degeneration. This disease has been rarely reported. An early diagnosis is seemed to be important since the skin lesion per se was premalignant, and generalized abnormalities including those of the central nervous system occurred concurrently.

    Full Text Available Objectives: The present study was carried to find out the frequency of haemolytic anaemia, to know the different etiological factors and their percentage in the region of marathwada, Maharashtra. Background: Knowledge of frequency and different etiological factors is essential for the information of magnitude and treatment of the patients. The present study was done in the department of pathology, Gov. Medical College, Aurangabad, district of Maharashtra. The patients from marathwada region of the Maharashtra were included in this study. The concerned study of “Haemoglobinopathies in Childhood” was conducted by Anil J in 1984 in the same institute. Methodology: Total 76 clinically suspected cases were investigated. For the study routine investigations like Hb estimation, peripheral blood smear examination, reticulocyte count and special investigations like sickling test, Hb solubility test, estimation of faetal haemoglobin and Hb electrophoresis were carried out. Results: Total 76 cases were studied. Out of it 51 cases were male (67.10% and 25 (32.89% cases were female. The patients are in the age group, 5 months to 45 years. Out of 76 cases 51 cases were diagnosed as haemolytic anaemia. In these 51 cases of haemolytic anaemia, 42 cases (82.35% of haemoglobinopathies, it cases (15.68% of malaria and one case (1.96% of auto immune haemolytic anaemia were found to have as causative factor. Conclusion: It showed that the frequency of haemolytic anaemia in studied 76 cases was 67.10%. In diagnosed 51 cases of haemolytic anaemia, the causative factor as haemoglobinopathy was 82.35% and other than haemoglobinopathy was 17.65%. It also showed that majority of the cases in this region were belonging to beta thalassaemia major, which is more common in western zone of India followed by sickle cell anaemia.

    Cholangiolocellular carcinoma (CoCC) is a rare malignant liver tumor derived from hepatic progenitor cells, which exist in the canals of Hering. We encountered a case of CoCC with an extremely poor clinical course, initially showing abnormally elevated serum alfa-fetoprotein (AFP). A 72-year-old male presented with a liver tumor and abnormally elevated serum AFP levels (16,399 ng/ml). We preoperatively diagnosed hepatocellular carcinoma and performed extended right hepatectomy, after which the serum AFP levels remarkably decreased to 97 ng/ml. Postoperatively, the disease was pathologically diagnosed as CoCC. Furthermore, immunohistochemical pathological findings were alcian blue negative, cytokeratin (CK) 7 partially positive, CK19 positive, hepatocyte paraffin-1 negative, membranous negative for epithelial membrane antigen, and AFP negative. Fifty-five days later, intra- and extrahepatic recurrence developed, and the patient died 65 days after surgery. Although CoCCs show favorable outcomes, these characteristics of our case were not previously reported. It is necessary to accumulate more information on CoCC. PMID:27363839

    2015-01-01

    Full Text Available Background: Sickle cell anaemia is an inherited disease in which the red blood cells become rigid and sticky, and change from being disc-shaped to being crescent-shaped. The change in shape is due to the presence of an abnormal form of haemoglobin. This results in severe pain and damage to some organs. Aim and Objective: The study was carried out to determine the levels of cytokine in sickle cell anemia. Material and Methods: Thirty confirmed sickle cell patients in steady state (HbSS-SS and thirty persons with normal haemoglobin (HbAA as well as sixteen sickle cell disease in crises (HbSS-cr between the ages of 15 to 30 years were selected in this study. Cytokines including interleukin 1 beta (IL- 1β, interleukin 2 (IL- 2, interleukin (IL-6, tumour necrosis factor alpha (TNF-α, and interferon gamma (IFN- λ were measured by commercially available ELISA kits. Results: The results obtained showed that the levels of TNF-α and IL-6 in sickle cell anaemia patients in crisis were significantly elevated when compared with sickle cell in steady state (P<0.05. Similarly, the levels of IL-1β, IL-6, and IFN- λ were significantly increased in sickle cell anaemia stable state when compared to HbAA subjects (P<0.05. Conclusion: This may probably implies that cytokine imbalance is implicated in the pathogenesis of sickle cell crisis. Also, cytokines could be used as an inflammatory marker as well as related marker in disease severity and hence therapeutic intervention.

  13. 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.

    In the elderly, even mild anaemia leads to significantly decreased quality of life and reduced survival rate. Therefore even mild anaemias should be worked up especially in the elderly. More than 75 % of all anaemias have a specific and treatable cause.Differential diagnosis of anaemia in the elderly is much more challenging compared to the differential diagnosis in younger patients: in older patients often more than one dysfunction is responsible for the anaemia simultaneously. Many routine laboratory parameters are changed by ageing and are therefore only of limited value for diagnosis of anaemia. Soluble transferinreceptor and hepcidin are two parameters feasible for differential diagnosis of the causes of anaemia in the elderly.The most common cause of iron deficiency anaemia in the elderly is gastrointestinal bleeding. Many causes for gastrointestinal bleeding -like angiodysplasia of the colon - can readily be treated with endoscopic therapy. For this reason, colonoscopy is part of the standard workup for elderly patients with iron-deficient anaemia (IDA) if no contraindications exist.Therapy of anaemia is based on the specific cause or the causes. In IDA, the first step other than causal treatment is to replace iron orally. If this is not tolerated because of side effects or does not lead to a sufficient rise in the haemoglobin level, intravenous iron replacement therapy is indicated. Folic acid deficiency is generally treated orally, whereas vitamin B12 deficiency is generally treated by the parenteral - preferably subcutaneous - route. In anaemia due to chronic renal failure and anaemia due to myelodysplastic syndromes, the underlying cause must be treated, furthermore erythropoiesis-stimulating agents can be indicated.

    Sensorimotor impairments are common in autism spectrum disorder (ASD), but they are not well understood. Here we examined force control during initial pulses and the subsequent rise, sustained, and relaxation phases of precision gripping in 34 individuals with ASD and 25 healthy control subjects. Participants pressed on opposing load cells with their thumb and index finger while receiving visual feedback regarding their performance. They completed 2- and 8-s trials during which they pressed at 15%, 45%, or 85% of their maximum force. Initial pulses guided by feedforward control mechanisms, sustained force output controlled by visual feedback processes, and force relaxation rates all were examined. Control subjects favored an initial pulse strategy characterized by a rapid increase in and then relaxation of force when the target force was low (Type 1). When the target force level or duration of trials was increased, control subjects transitioned to a strategy in which they more gradually increased their force, paused, and then increased their force again. Individuals with ASD showed a more persistent bias toward the Type 1 strategy at higher force levels and during longer trials, and their initial force output was less accurate than that of control subjects. Patients showed increased force variability compared with control subjects when attempting to sustain a constant force level. During the relaxation phase, they showed reduced rates of force decrease. These findings suggest that both feedforward and feedback motor control mechanisms are compromised in ASD and these deficits may contribute to the dyspraxia and sensorimotor abnormalities often seen in this disorder.

  16. Anaemia and radiation therapy

    International Nuclear Information System (INIS)

    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)

    Full Text Available 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 to 12 years born to women treated for preexisting or de novo hypothyroidism within 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 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

    Sickle cell anaemia (SCA) is one of the commonest chronic hemolytic anaemias in the Sudan; it is a disease with high mortality and morbidity. This study was conducted aiming to observe the clinical pattern of cardiac abnormalities in children with sickle cell anaemia, and to assess the relationship between the cardiac abnormalities and the severity of the disease. The study was conducted in sickle cell disease clinic at Khartoum Children Emergency Hospital. The study group consisted of 289 patients with sickle cell anaemia, age range from 6 months to 18 years. Data were collected using a questionnaire which include full history, clinical examination findings, chest x-rays, and Electro-cardiography. Tachycardia, systolic murmurs, and cardiomegaly were detected in 28%, 61%, and 54% of patients with SCA respectively. Left ventricular dilatation was observed in 51% of the study group, while right ventricular dilatation was observed in 22% of the patients. Left and right atrial dilatations were observed in 16% and 6% of the patients respectively. Contractility, ejection fraction (EF) were found almost always normal in all study subjects. Chamber dilatations were not associated with any abnormality in Left ventricular functions. Hemglobin (Hb) levels correlated negatively with cardiomegaly. Left Ventricular End Diastolic Dimension (LVEDD) correlates negatively with Hb levels and positively with the severity index. Only four patients (1%) had abnormal valves. In conclusion, cardiac abnormalities in patients with SCA correlate with the age of the patients and the severity of the disease. PMID:27493331

    International Nuclear Information System (INIS)

    To analyze the frequency and causes of anaemia in systemic lupus erythematosus (SLE) patients attending in department of medicine at tertiary care hospitals. Methods: This retrospective, descriptive and analytical study was planned to analyze the frequency and causes of anaemia in SLE patients attending the department of medicine at (MMC) and (LUMHS) hospitals during the period of Jan 2006 to Nov 2008. The criteria used in this study were from the American College of Rheumatology. Investigations recorded were blood complete picture, absolute values, peripheral smear, and reticulocyte count in all patients of anaemia. These investigations were necessary to analyse the cases of anaemia in SLE. All investigations were not done in all cases. Patients with hypochromic microcytic anaemia were advised to have serum iron and ferritin levels, seven patients with macrocytic anaemia were advised to have direct and indirect coomb's test, LFTs, serum LDH, serum B12 and folate levels. Patients with normochromic and normocytic anaemia were considered to have anaemia of chronic disease. Bone marrow aspiration and Hb electrophoresis were done in two patients with anaemia of chronic disease. Thirty adult patients were included in this study. Special proforma were prepared to record the information from case sheets of patients including basic information, symptomatology and laboratory investigations. Severity and various types of anaemias were recorded. Anaemia was graded according to severity, as mild (Hb 10-12 G/dl), Moderate (Hb 8-10 G/dl) and severe (Hb 1:80; and nineteen (63.33%) patients had anti ds DNA positive, titres >1:10. Conclusion: Haematologic abnormalities are common manifestations in patients with SLE. Most patients exhibit anaemia at some point during their disease course. (author)

    International Nuclear Information System (INIS)

    Objectives: To determine the frequency of anaemia in married women in Jutial, and to find out the relationship of risk factors of anaemia with levels of anaemia. Study Design: Cross-sectional study. Place and Duration of Study: Household survey carried out in Jutial, Gilgit 1st February 2008 to 30th April 2009. Patients and Method: Interview administered questionnaire along with blood sample collection using sterilized disposable syringes was used in this study on a total of 382 randomly selected, willing, married, non-pregnant, non-lactating women with one or more children. Results were considered significant if r-value was more than 0.5 with p-value less than 0.05. Results: Clinical analysis of the blood samples showed that the average haemoglobin (Hb) level was 12.8 g/dl. According to WHO standards, no woman had severe anaemia with Hb level below 7 g/dl. Majority of the women (77.5%) had normal Hb >= 12 g/dl. The calculated anaemia frequency of 22.5% was found to be little lower than that of national anaemia frequency of around 29 to 33%. Conclusion: Frequency of anaemia 22.5% can be attributed to good education system in Northern Area and the awareness of people towards health concerns. Another reason can be the initiatives by different NGOs working in the area specially Aga Khan Foundation to eradicate anaemia by developing a vast network of health facilities. Further research on the native foods, their extract nutritional values / iron contents and any special foods at higher altitudes may be more than 1500 meters can open new horizon to our understanding of anaemia in the northern areas.

    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.

    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....

    Congenital dyserythropoietic anaemia (CDA) is a heterogeneous group of rare genetic disorders that in humans is characterised by ineffective haematopoiesis with morphological abnormalities in erythroid precursor cells and secondary iron overload. In the 1990s, a syndrome of CDA with dyskeratosis and progressive alopecia was reported in Poll Hereford calves in Canada and the USA. We report the clinical and pathological findings in two Poll Hereford calves with this syndrome from separate properties in South Australia. The animals had a variably severe anaemia, associated with abnormal nucleated red blood cells in peripheral blood, and large numbers of rubricytes and metarubricytes with a characteristic nuclear ultrastructure in the bone marrow. Both calves were born with a wiry hair coat and a progressively 'dirty-faced' appearance associated with hyperkeratosis and dyskeratosis (apoptosis). PMID:23186092

    We reviewed the records of antenatal clinic attendees over a period of 9 years to determine the prevalence of anaemia at booking. The laboratory records of 8751 out of a total of 37,506 pregnant women who booked for antenatal care between 2004 and 2013 at the BMSH were reviewed. The effects of maternal age, educational status, parity, gestational age, haemoglobin genotype and infections on the prevalence of anaemia were investigated. The prevalence of anaemia at booking was 69.6%, most of whom had moderate anaemia. Anaemia was significantly prevalent in the 10-19 year age group, and in women with secondary education, in their 2nd trimester and with SS genotype. Anaemia also increased with gestational age, this however was not statistically significant. There was no statistical difference between those who are human immunodeficiency virus (HIV) positive and had anaemia and those who are HIV negative who also had anaemia. This study shows that anaemia in pregnant women is still unacceptably high considering the consequences and despite interventions on the ground to reduce prevalence. There is a need to review the intervention measures with emphasis on programmes that would increase awareness among pregnant women and the general public. PMID:27110932

    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. PMID:26214716

  9. Ineffective erythropoiesis and regulation of iron status in iron loading anaemias.

    The definition 'iron loading anaemias' encompasses a group of inherited and acquired anaemias characterized by ineffective erythropoiesis, low hepcidin levels, excessive iron absorption and secondary iron overload. Non-transfusion-dependent β-thalassaemia is the paradigmatic example of these conditions that include dyserythropoietic and sideroblastic anaemias and some forms of myelodysplasia. Interrupting the vicious cycle between ineffective erythropoiesis and iron overload may be of therapeutic benefit in all these diseases. Induction of iron restriction by means of transferrin infusions, minihepcidins or manipulation of the hepcidin pathway prevents iron overload, redistributes iron from parenchymal cells to macrophage stores and partially controls anaemia in β-thalassaemic mice. Inhibition of ineffective erythropoiesis by activin ligand traps improves anaemia and iron overload in the same models. Targeting iron loading or ineffective erythropoiesis shows promise in preclinical studies; activin ligand traps are in clinical trials with promising results and may be useful in patients with ineffective erythropoiesis.

    Full Text Available Anaemia in pregnancy defined as haemoglobin (Hb level of < 10 gm/dL, is a qualitative or quantitative deficiency of Hb or red blood cells in circulation resulting in reduced oxygen (O 2 -carrying capacity of the blood. Compensatory mechanisms in the form of increase in cardiac output (CO, PaO 2 , 2,3 diphosphoglycerate levels, rightward shift in the oxygen dissociation curve (ODC, decrease in blood viscosity and release of renal erythropoietin, get activated to variable degrees to maintain tissue oxygenation and offset the decreases in arterial O 2 content. Parturients with concomitant medical diseases or those with acute ongoing blood losses may get decompensated, leading to serious consequences like right heart failure, angina or tissue hypoxemia in severe anaemia. Preoperative evaluation is aimed at assessing the severity and cause of anaemia. The concept of an acceptable Hb level varies with the underlying medical condition, extent of physiological compensation, the threat of bleeding and ongoing blood losses. The main anaesthetic considerations are to minimize factors interfering with O 2 delivery, prevent any increase in oxygen consumption and to optimize the partial pressure of O 2 in the arterial blood. Both general anaesthesia and regional anaesthesia can be employed judiciously. Monitoring should focus mainly on the adequacy of perfusion and oxygenation of vital organs. Hypoxia, hyperventilation, hypothermia, acidosis and other conditions that shift the ODC to left should be avoided. Any decrease in CO should be averted and aggressively treated.

    Full Text Available Vitamin B12 deficiency is uncommon in pregnancy, it occurs in 10–28% of uncomplicated pregnancies, and is associated with a few complications. We present a case report of a 21-year-old patient with severe anaemia during late pregnancy caused by vitamin B12 deficiency. At 38 weeks gestation and with a BMI of 48.9, a history of rupture of membranes was given but not confirmed. On examination, she appeared pale and therefore full blood counts were done. Interestingly her haemoglobin (Hb levels were 3.7 g/dL. Folate and vitamin B12 levels were also found to be low, and the diagnosis of anaemia caused by vitamin B12 deficiency was made. After treatment with vitamin B12 injections, folic acid and blood transfusions, the patient’s haemoglobin levels improved from 3.7 g/dL to 10.7 g/dL. The conclusion is that effective history taking, diagnosis, and management can prevent many complications that are usually associated with vitamin B12 deficiency anaemia.

    This report demonstrates pulmonary haemorrhage as a differential cause of anaemia. Idiopathic pulmonary hemosiderosis is a rare disease in children; it is classically described as a triad of haemoptysis, pulmonary infiltrates on chest radiograph, and iron-deficiency anaemia. However, anaemia may be the only presenting feature of idiopathic pulmonary hemosiderosis in children due to occult pulmonary haemorrhage. In addition, the serum ferritin is falsely high in idiopathic pulmonary hemosiderosis which increases the diagnostic difficulty. We recommend that pulmonary haemorrhage be suspected in any child presenting with iron-deficiency anaemia and persistent bilateral pulmonary infiltrates. PMID:25904566

    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.

    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.

  1. 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

    The complete peripheral blood count analysis including laboratory screening tests of haemostasis and coagulation should be done in every patient before surgery, in order to detect specific abnormalities for primary or secundary haematologic disorder. These abnormalities might be very important course of perioperative and postoperative complications. Anaemia is the most frequent haematologic abnormality seen during preoperative period. Therapy approach depends on the type and anaemia degree, and also on the type and time of surgery. If surgery is not urgent specific therapy according to the anaemia type (iron therapy, vitamin B12, folic acid, corticosteroids, recombinant erythropoietin) should be given in all anaemias with deficiency of iron, megaloblastic anaemias, acquired haemolytic anaemias and anaemias in end stage renal disease. Transfusion of red cells are most frequently given in patients with normovolemic anaemias with haemoglobin level of 10.0 g/dl and hematocrit of 0.30, but lower levels in haemodynamic stable patients. Venesections should be done in patients with erythrocytosis in order to reduce total red cell volume, but taking into account the perioperative bleeding. Patients with leukocyte abnormalities suspected on primary haematologic disorder need urgent haematologic diagnostic procedures. In patients with leucocytosis the actual level of neutropenia is the bigger problem than the level of leucocytosis. In those patients treatment generally involves preventing infections, managing of febrile neutropenia with broad spectrum antibiotics and antifungal drugs, treatment with recombinant granulocyte hematopoetic factor, rarely transfusions of granulocyte concentrates and intravenous immunoglobulins.

    Full Text Available Available studies on prevalence of Nutritional Anaemia in India showed that 65% infants and toddlers, 60% children 1-6 years of age, 80% adolescent girls and 85% pregnant women were anaemic. Hence, this study was planned in the subjects visiting Katihar Medical College and Hospital. AIMS AND OBJECTIVES 1. To estimate the incidence of anaemia in inhabitants of Katihar. 2. To assess the morphological types of anaemia in different groups of people in this population. 3. To find out the association between anaemia and various socio-demographic factors. MATERIAL AND METHODS The present longitudinal study was carried out between December 2009 and mid August 2011. Using ‘Estimation setup technique’ with anaemia proportion taken as 40% with level of significance 5% and absolute allowable error 7%, the inflated sample size was 197 and was rounded off to 200. These subjects were selected using convenience sampling. Statistical methods adopted to address the objectives were frequencies, proportions, contingency coefficient and Chi-square test for proportion. RESULTS In the present study, Microcytic, hypochromic anaemia (41.5% was the most common type in both males and females. Highest incidence of anaemia in the present series was in the age group of 21-30 years being 37%. Incidence of anaemia was 62% in females and 38% in males. In present study, 130 cases (65% were among vegetarians and 90 cases (45% were among non-vegetarians; 76% cases were of low income group and 24% were middle income group. The commonest presenting symptoms were general weakness and tiredness (84%.

  5. A 3-marker index improves the identification of iron disorders in CKD anaemia.

    Directory of Open Access Journals (Sweden)

    Lucile Mercadal

    Full Text Available BACKGROUND: Iron disorders are common and complex in chronic kidney disease (CKD. We sought to determine whether a 3-marker index would improve the classification of iron disorders in CKD anaemia. METHODS: We studied the association between Hb level and iron indexes combining 2 or 3 of the following markers: serum ferritin (<40 ng/mL, transferrin saturation (TSAT<20% and total iron binding capacity (TIBC<50 µmol/L in 1011 outpatients with non-dialysis CKD participating in the Nephrotest study. All had glomerular filtration rates measured (mGFR by (51Cr-EDTA renal clearance; 199 also had hepcidin measures. RESULTS: The TSAT-TIBC-ferritin index explained Hb variation better than indexes combining TSAT-TIBC or ferritin-TSAT. It showed hypotransferrinaemia and non-inflammatory functional iron deficiency (ID to be more common than either absolute or inflammatory ID: 20%, 19%, 6%, and 2%, respectively. Hb was lower in all abnormal, compared with normal, iron profiles, and decreased more when mGFR was below 30 mL/min/1.73 m(2 (interaction p<0.0001. In patients with mGFR<30 mL/min/1.73 m(2, the Hb decreases associated with hypotransferrinaemia, non-inflammatory functional ID, and absolute ID were 0.83±0.16 g/dL, 0.51±0.18 and 0.89±0.29, respectively. Compared with normal iron profiles, hepcidin was severely depressed in absolute ID but higher in hypotransferrinaemia. CONCLUSIONS: The combined TSAT-TIBC-ferritin index identifies hypotransferrinaemia and non-inflammatory functional ID as the major mechanisms of iron disorders in CKD anaemia. Both disorders were associated with a greater decrease in Hb when mGFR was <30 mL/min/1.73 m(2. Taking these iron profiles into account may be useful in stratifying patients in clinical trials of CKD anaemia and might improve the management of iron therapy.

    Background & objectives: Fanconi anaemia (FA) is a syndrome with a predisposition to bone marrow failure, congenital anomalies and malignancies. It is characterized by cellular hypersensitivity to cross-linking agents such as mitomycin C (MMC). In the present study, a new approach was selected to investigate FANCA (Fanconi anaemia complementation group A) gene in patients clinically diagnosed with cellular hypersensitivity to DNA cross-linking agent MMC. Methods: Chromosomal breakage analysis was performed to prove the diagnosis of Fanconi anaemia in 318 families. Of these, 70 families had a positive result. Forty families agreed to molecular genetic testing. In total, there were 27 patients with unknown complementary types. Genomic DNA was extracted and total RNA was isolated from fresh whole blood of the patients. The first-strand cDNA was synthesized and the cDNA of each patient was then tested with 21 pairs of overlapping primers. High resolution melting curve analysis was used to screen FANCA, and LinReg software version 1.7 was utilized for analysis of expression. Results: In total, six sequence alterations were identified, which included two stop codons, two frames-shift mutations, one large deletion and one amino acid exchange. FANCA expression was downregulated in patients who had sequence alterations. Interpretation & conclusions: The results of the present study show that high resolution melting (HRM) curve analysis may be useful in the detection of sequence alteration. It is simpler and more costeffective than the multiplex ligation-dependent probe amplification (MLPA) procedure. PMID:27121516

    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)

  12. Effect of severe anaemia on renal function: a case-control study

    International Nuclear Information System (INIS)

    Aim: Anaemia, if severe, causes multi systemic functional changes. We tried to find out the effect of severe anaemia on renal function. Materials and Methods: A total of 66 patients with severe anemia and 10 healthy controls were recruited in this study. The cases were divided into following groups: group A: patients with Hb≤3 gm/dl (n=33); group B: patients with Hb≤6 but > 3 gm/dl (n=33); group C: healthy controls with normal renal function and Hb>12gm/dl. Out of 66 anaemic patients, 36 had nutritional anaemia (mainly iron deficiency; group A=20, group B=16), 24 patients were suffering from aplastic anaemia (group A=11, group B=13) and rest 6 had megaloblastic anaemia (group A=2, group B=4). No subject had hypertension, diabetes, primary renal dysfunction or any other systemic illness, affecting kidney. Various renal function test parameters and diagnostic renal failure indices were obtained for all subjects. GFR with 2-sample method after injection of 99m-Tc DTPA and ERPF with single sample method after injection of 131-I OIH were also calculated. Results: Fourteen patients had mild to moderate pedal edema (10 in group A and 4 in group B). Out of these patients, 8 had palpable liver and signs of systemic congestion. Signs of raised systemic venous pressure (raised JVP) were found in 7 patients of group A. In about 55% of patients, chest x-ray showed mild to moderately enlarged heart with disturbed cardiophrenic angle. Urine output was >600 ml/day in all cases. Results are presented. All renal functional parameters and indices were significantly reduced in anaemic patients and were suggestive of pre-renal failure. The reduction was correlating well with the severity of anaemia.Conclusion: Severe anaemia leads to renal dysfunction with alteration of minor and major renal failure indices, which can be characterized by sub-clinical and pre-biochemical non-oliguric pre-renal failure

    The present study examined the relationship between anaemia and tumour response to radiation given in air or HPO in C{sub 3}H mice transplanted with a mammary adenocarcinoma using a growth delay assay to assess radiation response. Radiation studies with these anaemic mice demonstrated that the tumour radiosensitivity was decreased when treatment was given in air. HPO was successful in overcoming the increased radioresistance associated with anaemia. This result suggested that tumours grown in anaemic mice have a higher hypoxic fraction than those grown in control mice. Changes in host physiology with chronic anaemia may contribute to the benefit seen with HPO but such alterations per se may be inadequate to maintain tumour oxygenation when treatment is given in air.

    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.

    A 47-year-old man was admitted to the hospital because of general convulsion, loss of consciousness and hyperthermia. A diagnosis of acute heat stroke was made clinically and neuroradiologically. As the consciousness level ameliorated, he developed severe abulia and mutism, then cerebellar ataxic syndrome (viz. truncal ataxia, hypermetria, ataxic speech and nystagmus). An MRI (diffusion weighted image; DWI) disclosed abnormal diffuse high signal intensity of the cerebellar cortex with reduced apparent diffusion coefficient (ADC). Two months later after the onset, truncal ataxia and dysarthria significantly improved, while dysmetria of the extremities rather worsened. At that time, the abnormal signal intensity of the cerebellar cortex disappeared, and the cerebellum became atrophic. The cerebellar blood flow was significantly decreased on brain SPECT (99mTc-ECD). The abnormal DWI signal intensity of the cerebellar cortex in the present patient may represent the cytotoxic edema of Purkinje cells resulting from heat stroke-related hyperthermia It is essential to repeat MRI examination for cerebellar pathology and to obtain better insight into sequelae in patients with acute heat stroke. Protirelin tartrate seemed to be valid for improvement of abulia in the present patient. Further study is indicated. PMID:19999144

  16. Incidence of nutritional anaemia among the under five children attending Ahmed Gasim hospital

    International Nuclear Information System (INIS)

    A survey was carried out in Khartoum North Ahmed Gasim specialist Hospital for children to identify aetiological factors that lead to incidence of nutritional anaemia among children under under five years of age. The sample consists of 192 patients taken from the hospital wards (experimental group), and 60 healthy children taken from out patient vaccination department of same hospital. A questionnaire was used as a tool for collection data regarding children and their families with emphasis to general information, socio-economic information, dietary information, anthropometric information, medical history and laboratory investigations including haemoglobin, hematocrit (PCV)%, peripheral blood picture, serum ferritin, serum folate and serum B12. Results show no correlation between anaemia and age R(0.1048) p12 deficiency. Some children affected had mixed deficiency anaemia (3.182). Iron deficiency without anaemia was common among healthy children (control) 22.8%. Some recommendations were set for the improvement of the existing situation e.g. health education, nutrition education with emphasis on intake of supplements and weaning diets rich in iron and folate. Follow up and surveillance program to compact nutritional anaemia should be adopted.(Author)

  17. Iron deficiency anaemia in Sri Lanka

    International Nuclear Information System (INIS)

    The commonest cause of nutritional anaemia in the Sri Lankan population is iron deficiency. The diets of the population belonging to the lower socio-economic groups contain little food of animal origin. Thus, their diets are deficient in easily absorbable (haem) iron; and are also heavily cereal-based. Therefore interference in the absorption of dietary iron also occurs. Iron-deficiency anaemia is not restricted to the so-called ''vulnerable groups'' in Sri Lanka, however, their greater demands make the problem not only commoner but also more severe. Among pregnant and lactating women anaemia is often associated with folate deficiency. It must also be noted that the low availability of dietary iron is compounded in large population groups. Malaria, presently raging on an epidemic scale is also a major contributory factor to the incidence of anaemia. The purpose of this study was to examine the iron status of pre-school children and pregnant women; to establish normal levels of biochemical indices at different trimesters; to record the effect of iron supplementation during pregnancy; and to record the bioavailability of iron from weaning foods and common adult diets. 6 figs, 14 tabs

    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

    Erythropoietin regulates erythropoiesis in a hypoxia-inducible manner. Here we generate inherited super-anaemic mice (ISAM) as a mouse model of adult-onset anaemia caused by erythropoietin deficiency. ISAM express erythropoietin in the liver but lack erythropoietin production in the kidney. Around weaning age, when the major erythropoietin-producing organ switches from the liver to the kidney, ISAM develop anaemia due to erythropoietin deficiency, which is curable by administration of recombinant erythropoietin. In ISAM severe chronic anaemia enhances transgenic green fluorescent protein and Cre expression driven by the complete erythropoietin-gene regulatory regions, which facilitates efficient labelling of renal erythropoietin-producing cells. We show that the majority of cortical and outer medullary fibroblasts have the innate potential to produce erythropoietin, and also reveal a new set of erythropoietin target genes. ISAM are a useful tool for the evaluation of erythropoiesis-stimulating agents and to trace the dynamics of erythropoietin-producing cells. PMID:23727690

    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%.

    Present case report refers to a 48-year-old man with genetic haemochromatosis (C282Y mut/mut) diagnosed at the age of 26. After aggressive iron depleting regimen carried out up to normalization of iron-related indexes, he received a maintenance regimen based on regular phlebotomies for about 20 years. In 2014, a marked reduction of both serum ferritin and transferrin saturation percent, without concomitant anaemia, was noted on two different occasions at 5-month interval. An obscure occult GI bleeding was suspected, but both upper and lower GI tract endoscopy were negative for abnormal findings, as also was a detailed abdominal US scan. The persistence of low iron-related indexes prompted the physicians to perform a videocapsule endoscopy, which showed an ulcerative bleeding lesion in the small bowel, not confirmed however by both anterograde and retrograde double-balloon enteroscopy. Further MRI and PET allowed the identification of a 3.5 cm large lesion, located outside the small bowel wall, suspected to be a gastrointestinal stromal tumour (GIST). A further laparoscopic procedure allowed the resection of 10 cm of midileum, which included the mass, fully consistent with GIST at pathology. PMID:26210325

    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

    The pathogenesis of the anaemia associated with rheumatoid disease is unclear. It has previously been shown that the degree of the anaemia correlates with the severity of the inflammatory disease and that serum from patients with arthritis inhibits erythropoiesis. This study was designed to examine whether interleukin 1 could be a mediator of the anaemia in rheumatoid arthritis. Radioimmunoassay of interleukin 1 beta in serum showed that patients with rheumatoid arthritis and associated anaem...

  4. The clinical and radiological features of Fanconi's anaemia pictorial review

    International Nuclear Information System (INIS)

    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.

    All viruses infecting fish must cross the surface mucosal barrier to successfully enter a host. Infectious salmon anaemia virus (ISAV), the causative agent of the economically important infectious salmon anaemia (ISA) in Atlantic salmon, Salmo salar L., has been shown to use the gills as its entry point. However, other entry ports have not been investigated despite the expression of virus receptors on the surface of epithelial cells in the skin, the gastrointestinal (GI) tract and the conjunctiva. Here we investigate the ISAV mucosal infection in Atlantic salmon after experimental immersion (bath) challenge and in farmed fish collected from a confirmed outbreak of ISA in Norway. We show for the first time evidence of early replication in several mucosal surfaces in addition to the gills, including the pectoral fin, skin and GI tract suggesting several potential entry points for the virus. Initially, the infection is localized and primarily infecting epithelial cells, however at later stages it becomes systemic, infecting the endothelial cells lining the circulatory system. Viruses of low and high virulence used in the challenge revealed possible variation in virus progression during infection at the mucosal surfaces. PMID:26490835

    Full Text Available Objective: To determine the prevalence of iron deficiency and megaloblastic anaemia at booking in the Specialist Hospital Gombe. Patients and methods:This was a cross sectional study of 461 women attending the antenatal clinic for their booking visit. The capillary technique was used for the estimation of the packed cell volume (PM/ while the morphologic type of anaemia was determined by the blood film appearance. The age, parity social class and gestational age at booking were obtained and analyzed. Results:Among the 461 women studied, 239 were anaemic thus making the prevalence of anaemia at booking to be 51.8%. Most, 67.4% were mildly anaemic, 30.5% were moderately anaemic while 2.1 % were severely anaemic. Three hundred and sixteen, (68.5% of the women booked in the second trimester while only 3.0% booked in the first trimester. The majority of the women, 293 (63.5% were in lower social class. Of the 239 anaemic women, 155 (64.9% had features of pure iron deficiency anaemia while only 1(0.4% had features of pure megaloblastic anaemia. Eighty three (34.7% had dim orphic blood picture while 238 (99.6% in total had features of iron deficiency anaemia. Although not anaemic by PCV the blood film of 26(5.6% showed features of pure iron deficiency. Conclusion: The contribution of iron deficiency to anaemia in pregnancy is exceedingly high. This further supports the continued use of iron supplements for all pregnant women preferably at no cost in the short run and economic empowerment of the women folk in the long run.

    A total of 8260 children between the ages of 6-59 months were analyzed to identify the risk factors associated with childhood anaemia in Ethiopia. The overall mean (SD/standard deviation) haemoglobin (Hgb) level among the under-five children was 10.7 (2.2) g/dl and 50.3% were anaemic. Childhood anaemia demonstrated an increasing trend with maternal anaemia levels of mild, moderate and severe anaemia: odds ratio of 1.82, 2.16 and 3.73 respectively (p< 0.01). Children whose mothers had no formal education were 1.38 times more likely to be anaemic (p<0.01). The poorest and poorer wealth index groups had 1.52 and 1.25 increased odds of childhood anaemia respectively (p< 0.01). Childhood anaemia in Ethiopia is a severe public health problem. Maternal anaemia and socio-economic status were found to be associated with anaemia in children. A holistic approach of addressing mothers and children is of paramount importance. PMID:24069773

  9. Acute lymphoblastic leukemia in a child with fanconi's anaemia

    International Nuclear Information System (INIS)

    Fanconi anaemia (FA) is an autosomal recessive inherited disorder with progressive bone marrow failure, associated congenital malformation and solid and haematological malignancies. Acute myeloid leukemia is the commonest haematological malignancy followed by myelodysplastic syndrome in children with FA. FA transformed into acute lymphoblastic leukemia (ALL) is a rare phenomenon and one of the rarest haematological malignancies associated with this disorder. We are reporting a 13 years old girl with FA and positive chromosomal breakage. She required regular blood product transfusion. She was planned for haematopoietic stem cell transplantation (HSCT) but the sibling-matched donor was found to have chromosomal breaks as well. Later on, her peripheral smear showed blast cell. Bone marrow showed pre-B ALL. She was started on chemotherapy but died shortly due to complications of the treatment. For this rare condition conservative management is indeed essential, however, safe and appropriate chemotherapy regimen is needed. (author)

  10. 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

    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

    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

    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.

    Full Text Available Background: Nutritional anaemia in pregnant women is one of the India’s major public health problems, despite the fact that this problem is largely preventable & easily treatable. Objectives: 1.To determine the prevalence of anaemia in pregnant women. 2. To assess the epidemiological determinants of anaemia in pregnancy. Methodology: A descriptive case series study was conducted among the pregnant women from second trimester onwards from urban field practice area from 1st March 2010 to 31st July 2010 by using pre-designed, pre-tested, structured schedule. Haemoglobin estimation was done by Sahli’s method & anaemia was graded according to WHO criteria. Statistical analyses were done by percentages and proportions, Mean and Standard Deviation (S.D, Chi-square test. Results: A high prevalence (82.9% of anaemia (Haemoglobin - < 11.0gm/dl was observed among 228 pregnant women. Majority (50.4% had moderate degree of anaemia (Haemoglobin - 7.0 to 10.0 gm/dl and 7.0% had severe anaemia (Haemoglobin - < 7.0 gm/dl. Severity of anaemia was more in 26 years of age, from nuclear families, educated upto secondary level, having vegetarian diet, parity two or more & those in third trimester with two or more abortions, although statistically not significant. However, anaemia prevalence was significantly higher among those subjects from below Class IV socio-economic status, those with less than two years of spacing between previous and index pregnancies & with less than two months IFA tablet consumption. Conclusion: A very high prevalence of anaemia in pregnancy needs mandatory regular supply of IFA tablets to adolescent and pregnant women from 4th month onwards till 3-6 months post-partum along with correction of other nutritional deficiencies and timely intervention for reducing the burden of related diseases.

    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

    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. PMID:15139958

    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.

    Masking of the macrocytic expression of megaloblastic anaemia (MA) by coexisting thalassaemia, iron deficiency and chronic illness has been widely reported. We described the haematological and clinical features of 20 Chinese patients with MA presenting with mean corpuscular volume (MCV) values of haemoglobin, MCV, red cell distribution width (RDW), reticulocyte index, platelet count and serum bilirubin. All provided clues to maturation disorders within the marrow. A decision flowchart for the diagnosis of MA without macrocytosis was proposed. In the studied population, by using the parameters of haemoglobin or = 16% and reticulocyte index peripheral blood smear examination in the diagnostic procedures for such patients, as well as the importance of paying attention to patients' medical history, racial background and previous MCV value.

    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.

  12. The Fanconi anaemia pathway orchestrates incisions at sites of crosslinked DNA.

    Science.gov (United States)

    Crossan, Gerry P; Patel, Ketan J

    2012-01-01

    Fanconi anaemia (FA) is a rare, autosomal recessive, genetically complex, DNA repair deficiency syndrome in man. Patients with FA exhibit a heterogeneous spectrum of clinical features. The most significant and consistent phenotypic characteristics are stem cell loss, causing progressive bone marrow failure and sterility, diverse developmental abnormalities and a profound predisposition to neoplasia. To date, 15 genes have been identified, biallelic disruption of any one of which results in this clinically defined syndrome. It is now apparent that all 15 gene products act in a common process to maintain genome stability. At the molecular level, a fundamental defect in DNA repair underlies this complex phenotype. Cells derived from FA patients spontaneously accumulate broken chromosomes and exhibit a marked sensitivity to DNA-damaging chemotherapeutic agents. Despite complementation analysis defining many components of the FA DNA repair pathway, no direct link to DNA metabolism was established until recently. First, it is now evident that the FA pathway is required to make incisions at the site of damaged DNA. Second, a specific component of the FA pathway has been identified that regulates nucleases previously implicated in DNA interstrand crosslink repair. Taken together, these data provide genetic and biochemical evidence that the FA pathway is a bona fide DNA repair pathway that directly mediates DNA repair transactions, thereby elucidating the specific molecular defect in human Fanconi anaemia.

  17. Prevention of gamma radiation induced anaemia in mice by diltiazem

    International Nuclear Information System (INIS)

    Intraperitoneal administration of diltiazem (DTZ), half an hour prior to whole body gamma irradiation (2.5, 5.0, and 7.5 Gy), showed the protection of animals from radiation-induced anaemia. Radiation exposure significantly (p<0.001) reduced the number of pro- and normoblasts in bone marrow and red blood cell (RBC) counts, hemoglobin (Hb), hematocrit (Hct), and erythropoietin (EPO) level in blood, but increased myeloid/erythroid ratio. At all the radiation doses, the maximum decrease in these values was noted on the 3rd day, followed by a gradual recovery from the 7th day, but it was not recorded as normal even until the end of experimentation. In animals pretreated with DTZ, these values were measured higher at all the time periods in comparison to corresponding control, and these were almost normal at the last autopsy interval only at 2.5 Gy radiation dose. DTZ maintained the higher EPO level in blood, which acted on bone marrow and spleen colony forming unit for erythroblast (CFU-E), and stimulated such cells to produce RBCs. These results confirm that DTZ has the potency to alter anaemic condition favorably through the protection of bone marrow stem cells, and subsequently it maintains the higher number of pro-and normoblasts in bone marrow, RBC counts, Hb, Hct percentage, and EPO level in blood and the lower myeloid/erythroid ratio in bone marrow.

    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.

    Directory of Open Access Journals (Sweden)

    Michaël Boele van Hensbroek

    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.

    Cancer-associated microangiopathic haemolytic anaemia (CA-MAHA) is a syndrome characterised by Coombs-negative haemolytic anaemia and thrombocytopenia. It is primarily seen in advanced solid tumours and is distinct from thrombotic thrombocytopenic purpura/haemolytic uraemic syndrome. Diagnosis is often delayed and patients have a high mortality. We present the case of CA-MAHA in a patient with metastatic breast cancer treated successfully with early initiation of chemotherapy. In addition, we report longitudinal laboratory evaluation of circulating tumour cells and microparticles and suggest a hypothesis for the mechanism behind CA-MAHA. PMID:26744538

  4. Radioisotopes of iron in investigation of anaemia in malnutrition

    International Nuclear Information System (INIS)

    Iron absorption from a simple breakfast meal by a normal adult was done by the whole body counting system and blood radioactivity measurement. Results seem to be in good agreement and both the methods are found to be standard for measurements of iron absorption from food. In iron deficiency anaemia associated with malnutrition improvement of nutritional condition has been found to increase both haemoglobin level and iron absorption possibly by way of improving the ability of intestinal mucosa to absorb more iron from food and by better utilization of iron by erythropoietic system. Thus improvement of nutritional status is a prerequisite to treatment of iron deficiency anaemia. (author)

    2010-01-01

    We showed that docosahexaenoic acid (DHA) supplementation during pregnancy and lactation was associated with more mildly abnormal (MA) general movements (GMs) in the infants. Since this finding was unexpected and inter-individual DHA intakes are highly variable, we explored the relationship between GM quality and erythrocyte DHA, arachidonic acid (AA), DHA/AA and Mead acid in 57 infants of this trial. MA GMs were inversely related to AA, associated with Mead acid, and associated with DHA/AA in a U-shaped manner. These relationships may indicate dependence of newborn AA status on synthesis from linoleic acid. This becomes restricted during the intrauterine period by abundant de novo synthesis of oleic and Mead acids from glucose, consistent with reduced insulin sensitivity during the third trimester. The descending part of the U-shaped relation between MA GMs and DHA/AA probably indicates DHA shortage next to AA shortage. The ascending part may reflect a different developmental trajectory that is not necessarily unfavorable. PMID:20022733

    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.

  10. The adaptive response of mouse tumours to anaemia and retransfusion

    International Nuclear Information System (INIS)

    Exchange transfusion methods have been developed to alter the haematocrit of tumour-bearing mice. The effects of anaemia and its correction by blood transfusion on the radiosensitivity of two mouse tumours (SCCVII/St and RIF-1) were studied using excision, in vivo/in vitro assay. Acute reduction in haematocrit caused a high degree of radioresistance equivalent to an increase in the hypoxic fractions by factors of 10 (SCCVII/St) and 30 (RIF-1). As the duration of anaemia was prolonged, radioresistance was lost until within about 6 h normal radiosensitivity was observed even though the anaemia persisted. The restoration of the normal haematocrit by red blood cell transfusion after 24 h of anaemia caused increased radiosensitivity equivalent to a reduction in the hypoxic fraction by factors of 5 (SCCVII/St) and 10 (RIF-1), but again the effect was transient and normal radiosensitivity re-established within 24-48 h of retransfusion. Measurements of 14C misonidazole (MISO) binding to RIF-1 tumours after these procedures indicated changes in the number of hypoxic cells which were qualitatively almost identical to those using the cell survival endpoint, leading to the belief that changes in oxygenation were reponsible for the altered radiosensitivity.

    Full Text Available Background. Diabetes mellitus characterized by hyperglycaemia presents with various complications amongst which anaemia is common particularly in those with overt nephropathy or renal impairment. The present study has examined the contribution of the hyperglycaemic environment in diabetic rats to the anaemia associated with diabetes mellitus. Method. Sixty male albino rats weighing 175–250 g were selected for this study and divided equally into control and test groups. Hyperglycaemia was induced with 170 kgbwt−1 alloxan intraperitoneally in the test group while control group received sterile normal saline. Blood samples obtained from the control and test rats were assayed for packed cell volume (PCV, haemoglobin (Hb, red blood cell count (RBC, reticulocyte count, glucose, plasma haemoglobin, potassium, and bilirubin. Result. Significant reduction (P<0.01 in PCV (24.40±3.87 versus 40.45±3.93 and haemoglobin (7.81±1.45 versus 13.39±0.40 with significant increase (P<0.01 in reticulocyte count (12.4±1.87 versus 3.69±0.47, plasma haemoglobin (67.50±10.85 versus 34.20±3.83, and potassium (7.04±0.75 versus 4.52±0.63 was obtained in the test while plasma bilirubin showed nonsignificant increase (0.41±0.04 versus 0.24±0.06. Conclusion. The increased plasma haemoglobin and potassium levels indicate an intravascular haemolytic event while the nonsignificant increased bilirubin showed extravascular haemolysis. These play contributory roles in the anaemia associated with diabetes mellitus.

  13. Iron deficiency anaemia in pre-school (1- 6 years) in Al Shigla area (Khartoum State) :Prevalence and Aetiology

    International Nuclear Information System (INIS)

    iron deficiency anaemia (IDA) is a public health problem throughout the world. Childhood iron deficiency anaemia. A prospective survey (systematic, cluster sampling) was carried out among pre-school children in Alshigla area (Khartoum State), to study the prevalence and aetological factors of IDA. 170 children selected for general nutritional evaluation, 110 of them for haemoglobin levels and morphological classification of anaemia, 70 for further investigations(serum iron, unsaturated iron binding capacity, total iron binding capacity). The population at Alshigla were living in poor condition 85.3% relied on water brought by tankers which showed poor hygienic standard, 90% lived in extended families 54.1% had income level less than LS 3000/day irrespective of family size or mode of spending. A sample of 170 children showed (84.1%) normal nutritional status with 4.7% severe cases with high consumption of cereals low meat, fish and poultry group and vitamin C(22.9%). Disease episodes showed 67.7% had diarrhoea, 22.4% had giardia, 12.9% had malaria and 10.6% had worm infestation. This most probably due to unsanitary living condition. Haemoglobin analysis using Enzyme Linked Immunosorbent assay technique (ELISA) for 110 of the children, showed high prevalence of anaemia (96.4%), 66% prevalence of IDA. Further haematological investigations of 50 of the children confirmed them as IDA cases.Thus the high prevalence of IDA in Alshigla was multi-factorial, inadequate take of dietary iron and of vitamin C, high intake of cereals and legumes, low intake of meat, poultry and fish group (MPF),and high tea consumption, thus food provides inadequate supply of iron and were rich in inhibitors of iron absorption. In addition episodes of diseases that may influence food (hence iron) utilisation contributed to the prevalence of IDA

    Full Text Available Background: Abnormal lipid homeostasis has been reported in sickle cell anaemia (SCA as well as in other haematological disorders. However, there is little information on the lipid profile of SCA subjects in vaso-occlusive crisis (VOC. This study determined the lipid profile of adult SCA subjects in VOC and in steady state (SSCA. Materials and Methods: Fifty-eight (58 adults with HbSS (30 in steady state and 28 in vaso-occlusive crisis and 24 age-matched healthy individuals with HbAA genotype were recruited into this study. Standard methods were used for the determination of blood pressure (BP, packed cell volume (PCV, total white blood cell count (WBC and haemoglobin phenotype. After an overnight fast, 5 ml of venous blood was obtained from each SSCA and the controls while samples were collected upon admission in the VOC group. Plasma lipid profile was determined using enzymatic method. Differences between two groups were determined using independent Student′s t-test or Man-Whitney U as appropriate. P-values less than 0.05 were considered significant. Results: Plasma total cholesterol (TC and high density lipoprotein (HDL were significantly lower while the ratio of triglyceride (TG to HDL (TG/HDL was significantly higher in SSCA compared with the controls. Low density lipoprotein (LDL and TC were significantly lower in SCA subjects in VOC compared with controls. However, TC, TG, LDL and TG/HDL were significantly lower while HDL was significantly higher in VOC compared with SSCA. Conclusion: Sickle cell anaemia subjects have defective fasting lipid metabolism which becomes pronounced with VOC.

    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.

  17. Vitamin B12 deficiency - a major cause of megaloblastic anaemia in patients attending a tertiary care hospital

    International Nuclear Information System (INIS)

    Folate and vitamin B12 deficiencies have been known to cause megaloblastic anaemia. Since the deficiencies of these two vitamins are very common in Pakistani population, it would be imperative to investigate their role in causing megaloblastic anaemia. The objective of this study was to find out the contribution of folate and vitamin B12 deficiencies in causing megaloblastic anaemia in our patient population. Methods: In this retrospective cohort study, clinical records of 220 patients (101 females and 119 males with an age range of 1 - 80 years) who presented themselves with macrocytic anaemia at the Aga Khan University Hospital were collected. Data pertaining to complete blood count and serum levels of folate and vitamin B12 were analysed. Results: The mean haemoglobin (Hb) level was 6.8 +- 0.2 gm/dl. Sixty-nine percent of the patients had severe anaemia (Hb<8 gm/dl). Mean +- SEM values of haemoglobin, serum folate and serum B12 were not significantly different between males and females (Hb 6.4 +- 0.3 gm/dl vs 6.3 +- 0.3 gm/dl; folate 6.9 +- 0.8 mu g/ml vs 7.8 +- 1 mu g/ml; B12 259 +- 65 mu g/ml vs 225 +- 45 mu g/ml, respectively). Linear regression analysis showed that serum folate was inversely related with the mean corpuscular volume (MCV, p=0.04). Spearman's correlation analysis indicated an inverse mild association between MCV and serum folate (correlation coefficient= -0.18). Folate deficiency was 43.4%, while vitamin B12 deficiency was 78.5% in these patients. Seventy-one percent of folate-deficient patients had vitamin B12 deficiency as well, while 26.1% of patients with B12 deficiency had a co-occurrence of folate deficiency. Conclusion: Vitamin B12 deficiency appears to be the major factor leading to megaloblastic anaemia in our study population. Inadequate dietary intake, over-cooking of our food and poor absorption might be contributing to high prevalence of vitamin B12 deficiency in this population. (author)

  18. SPORTS ANAEMIA IN ENDURANCE ATHLETES: A PHYSIOLOGICAL PHENOMENON

    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

    The phenotypic expression of sickle cell anaemia varies greatly among patients and longitudinally in the same patient. It influences all aspects of the life of affected individuals including social interactions, intimate relationships, family relations, peer interactions, education, employment, spirituality and religiosity. The clinical manifestations of sickle cell anaemia are protean and fall into three major categories: anaemia and its sequelae;pain and related issues; andorgan failure including infection. Recent studies on the pathogenesis of sickle cell anaemia have centred on the sequence of events that occur between polymerisation of deoxy haemoglobin (Hb) S and vaso-occlusion. Cellular dehydration, inflammatory response and reperfusion injury seem to be important pathophysiological mechanisms. Management of sickle cell anaemia continues to be primarily palliative in nature, including supportive, symptomatic and preventative approaches to therapy. Empowerment and education are the major aspects of supportive care. Symptomatic management includes pain management, blood transfusion and treatment of organ failure. Pain managment should follow certain priniciples that include assessment, individualisation of therapy and proper utilisation of opioid and nonopioid analgesics in order to acheive adequate pain relief. Blood selected for transfusion should be leuko-reduced and phenotypically matched for the C, E and Kell antigens. Exchange transfusion is indicated in patients who are transfused chronically in order to prevent or delay the onset of iron-overload. Acute chest syndrome is the most common form of organ failure and its management should be agressive, including adequate ventilation, multiple antibacterials and simple or exchange blood transfusion depending on its severity. Preventitive therapy includes prophylactic penicillin in infants and children, blood transfusion (preferably exchange transfusion) in patients with stroke, and hydroxyurea in patients

    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.

    2016-07-01

    Anaemia of inflammatory disease is a common cause of anaemia in routine veterinary practice. It is most often mild to moderate, normocytic, normochromic and non-regenerative. Shortened red cell life span, inhibition of iron metabolism and impaired bone marrow response to erythropoietin all contribute to its development. Although anaemia of inflammatory disease is a well-known cause of anaemia in dogs and cats, there is a lack of epidemiological information because specific diagnostic criteria have not been established in veterinary species. Anaemia of inflammatory disease is associated with a poor outcome in various disease states in human medicine; however, its clinical significance and treatment in veterinary medicine are not well understood. This review article describes anaemia of inflammatory disease in dogs and cats and considers its potential significance. PMID:27385622

    International Nuclear Information System (INIS)

    To identify the etiological factors responsible for increased incidence of megaloblastic anaemia in district Gilgit. A retrospective analysis of sixty one patients (n=61) was done who were diagnosed as patients of chronic anaemia. They were referred for bone marrow examination. Out of these, twenty two cases (n=22) were diagnosed as megaloblastic anaemia. Serum samples of all the patients were sent to AFIP for estimation of B12 and folate levels. A detailed history with special emphasis on dietary habits was noted. Patients included in the study were either retired Armed Forces personal (n=6) who had been living in district Gilgit for over period of five years. Other patients (n=16) were serving Army personal who had been serving in district Gilgit for over one year. Out of twenty two patients (n=22), only three (n=3, 13.6 %) had poor dietary history. A total of sixteen (n=16, 72.7%) patients had diarrhoea .Out of these sixteen, ten patients (n=10, 62.5%) had vegetative forms of gardia lamblia in their stools specimens. All (n=10) patients, who had giardiasis, had dyspeptic symptoms as their initial complaints. Twenty two serum samples were sent to AFIP for Vit B12 and folate level estimation. A total of seven patients (n=7, 31.8%) had low Vit B12 levels, while one patient (n=1, 4.5 %) had decreased level of both Vit B12 and folate. Chronic giardiasis and dietary insufficiency may be a major cause for increased incidence of megaloblastic anaemia in district Gilgit. (author)

  6. Hematopoiesis research in aplastic anaemia induced by accidental protracted radiation

    International Nuclear Information System (INIS)

    Over the past few years there have been 2 radiation-related accidents involving a large number of individuals: the April 1986 accident in Chernobyl nuclear power station in the Ukraine and the September 1987 accident in Goiania, Brazil. These 2 radiation-related accidents highlight the major question raised by radiation-induced injury to the haematopoietic system, that is: does a given patient suffer from a reversible or an irreversible haematopoietic stem cell damage ? Although about 350 radiation accidents involving several thousand people are known from the literature, in-depth haematopoiesis analyses of individuals after a radiation-related accident have rarely been reported. In this paper we present the case of a young man with radiation-induced aplasia and compare some biological data to those of 16 normal individuals and of 17 patients with acquired aplastic anaemia. Our patient was clinically and biologically (as assessed by long-term bone marrow culture) indistinguishable from patients with idiopathic acquired aplastic anaemia. Furthermore, therapeutic attitudes in this patient are discussed. In-depth study of such radiation-induced aplastic anaemia cases can shed some light in the understanding of this disease and may help in therapeutic decisions. (author)

  7. Cloning, expression and preliminary crystallographic analysis of the equine infectious anaemia virus (EIAV) gp45 ectodomain

    International Nuclear Information System (INIS)

    The equine infectious anaemia virus gp45 ectodomain was cloned, expressed and crystallized. Preliminary crystallographic analysis showed that the protein belonged to space group P63 and contained one molecule per asymmetric unit. Like human immunodeficiency virus (HIV), equine infectious anaemia virus (EIAV) belongs to the lentivirus genus. The first successful lentiviral vaccine was developed for EIAV. Thus, EIAV may serve as a valuable model for HIV vaccine research. EIAV glycoprotein 45 (gp45) plays a similar role to gp41 in HIV by mediating virus–host membrane fusion. The gp45 ectodomain was constructed according to the structure of HIV gp41, with removal of the disulfide-bond loop region. The protein was expressed in Escherichia coli and crystallized following purification. However, most of the crystals grew as aggregates and could not be used for data collection. By extensively screening hundreds of crystals, a 2.7 Å resolution data set was collected from a single crystal. The crystal belonged to space group P63, with unit-cell parameters a = b = 46.84, c = 101.61 Å, α = β = 90, γ = 120°. Molecular replacement was performed using the coordinates of various lengths of HIV gp41 as search models. A long bent helix was identified and a well defined electron-density map around the long helix was obtained. This primary model provided the starting point for further refinement

    We use evidence-based algorithms to treat abnormal scarring, including keloids and hypertrophic scars (HSs). This involves a multimodal approach that employs traditional methods such as surgical removal, postoperative radiotherapy, corticosteroid injection, laser, and silicone gel sheets. As a result, the rate of abnormal scarring recurrence has decreased dramatically over the past 10 years. However, several problems remain to be solved. First, despite the optimization of a radiotherapy protocol, over 10% of cases who are treated with surgery and postoperative radiotherapy still recur in our facility. Second, the treatment options for cases with huge keloids are very limited. To address these problems, we performed basic research on the mechanisms that drive the formation of keloids and HSs. Extrapolation of these research observations to the clinic has led to the development of two treatment strategies that have reduced the rate of abnormal scar recurrence further and provided a means to remove large scars. Our finite element analysis of the mechanical force distribution around keloids revealed high skin tension at the keloid edges and lower tension in the keloid center. Moreover, when a sophisticated servo-controlled device was used to stretch wounded murine dorsal skin, it was observed that the stretched samples exhibited upregulated epidermal proliferation and angiogenesis, which are also observed in keloids and HSs. Real-time RT-PCR also revealed that growth factors and neuropeptides are more strongly expressed in cyclically stretched skin than in statically stretched skin. These findings support the well-established notion that mechanical forces on the skin strongly influence the cellular behavior that leads to scarring. These observations led us to focus on the importance of reducing skin tension when keloids/HSs are surgically removed to prevent their recurrence. Clinical trials revealed that subcutaneous/fascial tensile reduction sutures, which apply

    Clinical studies showed that high doses of recombinant human erythropoietin (rHuEPO) used to correct anaemia in chronic kidney disease (CKD) hyporesponsive patients may lead to deleterious effects. The aim of this study was to analyze the effects of rHuEPO in doses usually used to correct CKD-anaemia (100, 200 IU/kg body weight (BW) per week) and in higher doses used in the treatment of hyporesponsive patients (400, 600 IU/kg BW per week), focusing on renal damage, hypoxia, inflammation and fibrosis. Male Wistar rats with chronic renal failure (CRF) induced by 5/6 nephrectomy were treated with rHuEPO or with vehicle, over a 3-week period. Haematological, biochemical and renal function analyses were performed. Kidney and liver mRNA levels were evaluated by quantitative real-time polymerase chain reaction (qPCR) and protein expression by Western blot and immunohistochemistry. Kidney histopathological evaluations were also performed. The CRF group developed anaemia, hypertension and a high score of renal histopathologic lesions. Correction of anaemia was achieved with all rHuEPO doses, with improvement in hypertension, renal function and renal lesions. In addition, the higher rHuEPO doses also improved inflammation. Blood pressure was reduced in all rHuEPO-treated groups, compared to the CRF group, but increased in a dose-dependent manner. The current study showed that rHuEPO treatment corrected anaemia and improved urinary albumin excretion, particularly at lower doses. In addition, it is suggested that a short-term treatment with high doses, used to overcome an episode of hyporesponsiveness to rHuEPO therapy, can present benefits by reducing inflammation, without worsening of renal lesions; however, the pro-hypertensive effect should be considered, and carefully managed to avoid a negative cardiorenal impact.

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

    Directory of Open Access Journals (Sweden)

    Reverberi Roberto

    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.

    Full Text Available Anaemia is one of the significant public health problems among children in the world. Understanding risk factors of anaemia provides more insight to the nature and types of policies that can be put up to fight anaemia. We estimated the prevalence and risk factors of anaemia in a population-based, cross-sectional survey.Blood samples from 11,711 children aged between 6 months and 14 years were collected using a single-use, spring-loaded, sterile lancet to make a finger prick. Anaemia was measured based on haemoglobin concentration level. The generalized linear model framework was used to analyse the data, in which the response variable was either a child was anemic or not anemic.The overall prevalence of anaemia among the children in Kenya was estimated to be 28.8%. Across each band of age within which the definition of anaemia remained constant (0–4, 5–11, and 12–14 years old, the prevalence of anaemia declined with each year of age. [corrected]. The risk of anaemia was significantly higher in male than female children. Mothers with secondary and above education had a protective effect on the risk of anaemia on their children. Malaria diagnosis status of a child was positively associated with risk anaemia.Controlling co-morbidity of malaria and improving maternal knowledge are potential options for reducing the burden of anaemia.

    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 (Paccess and use through market channels. The YYB project may be effective for reducing anaemia and improving feeding practices. PMID:21929638

    In four unrelated patients with chronic haemolysis and markedly reduced red blood cell (RBC) glutathione (49.5%, 12.6%, 11.5% and 15% of the normal concentration respectively), a severe glutathione synthetase (GSH-S, EC 6.3.2.3) deficiency was found. One case exhibited a neonatal haemolytic anaemia associated with oxoprolinuria, but without neurological manifestations. The family study revealed GSH-S activity in both parents to be around half the normal level, a finding consistent with the presumed autosomal recessive mode of inheritance of this enzymopathy. Two cases exhibited a well-compensated haemolytic syndrome without anaemia or splenomegaly at steady state. One of these cases was diagnosed after an episode of acute haemolytic anaemia after fava bean ingestion. The remaining patient suffered from moderate to severe chronic non-spherocytic haemolytic anaemia and splenomegaly, and required occasional blood transfusion for a haemolytic crisis associated with drug ingestion. In this patient, the anaemia was corrected by splenectomy. In addition to GSH-S, a panel of 16 other RBC enzyme activities was also studied in all the patients. Hexokinase, aldolase, glucose-6-phosphate dehydrogenase and pyruvate kinase activities all increased; these increases were to be expected, given the rise in the number of circulating reticulocytes. In two patients, the incubation of RBCs with hydrogen peroxide revealed an enhanced production of malonyldialdehyde. DNA analysis showed a homozygous state for 656 A-->G mutation in patients 2 and 3. The GSH-S gene of patient 1, studied elsewhere, revealed an 808 T-->C. The GSH-S gene of patient 4 was not available for study. The present study demonstrates that GSH-S deficiency is also present in Spain and further supports the molecular and clinical heterogeneity of this enzymopathy PMID:11167850

    Full Text Available Abstract Background Post-transplant anaemia remains a common problem after kidney transplantation, with an incidence ranging from nearly 80% at day 0 to about 25% at 1 year. It has been associated with poor graft outcome, and recently has also been shown to be associated with increased mortality. Our transplant unit routinely administers oral iron supplements to renal transplant recipients but this is frequently accompanied by side effects, mainly gastrointestinal intolerance. Intravenous iron is frequently administered to dialysis patients and we sought to investigate this mode of administration in transplant recipients after noticing less anaemia in several patients who had received intravenous iron just prior to being called in for transplantation. Methods This study is a single-centre, prospective, open-label, randomised, controlled trial of oral versus intravenous iron supplements in renal transplant recipients and aims to recruit approximately 100 patients over a 12-month period. Patients will be randomised to receive a single dose of 500 mg iron polymaltose (intravenous iron group or 2 ferrous sulphate slow-release tablets daily (oral iron group. The primary outcome is time to normalisation of haemoglobin post-transplant. Prospective power calculations have indicated that a minimum of 48 patients in each group would have to be followed up for 3 months in order to have a 90% probability of detecting a halving of the time to correction of haemoglobin levels to ≥110 g/l in iron-treated patients, assuming an α of 0.05. All eligible adult patients undergoing renal transplantation at the Princess Alexandra Hospital will be offered participation in the trial. Exclusion criteria will include iron overload (transferrin saturation >50% or ferritin >800 μg/l, or previous intolerance of either oral or intravenous iron supplements. Discussion If the trial shows a reduction in the time to correction of anaemia with intravenous iron or less side

    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.

    Full Text Available Anaemia is a major public health problem that has affected around 25% of the world’s population. An analytical cross-sectional study was performed on 313 female undergraduates residing in hostels of University of Sri Jayewardenepura, Sri Lanka, during year 2011. Objective of this study was to determine prevalence and contributing factors to anaemia among the study population. Haemoglobin concentration was assayed using cyanomethaemoglobin method. A pretested self-administered questionnaire was used to retrieve information regarding dietary habits and personal factors of participants. Descriptive statistical methods, chi-square test, and independent sample t-test were used to analyze data. Of the 302 females, 17.5% (n=53 had mild anaemia and 7.9% (n=24 had moderate anaemia. Severely anaemic individuals were not observed. Participants’ dietary habits and personal factors were not significantly associated with prevalence of anaemia (whether a participant is a vegetarian or not (P=0.525, drinking tea within one hour of a meal (P=0.775, frequency of consumption of red meat, fish, and eggs (P=0.499, antihelminthic treatment within past year (P=0.792, and menorrhagia (P=0.560. Anaemia in the study population is below the average for Sri Lankan data. Diet and selected medical conditions were not a causative factor for anaemia in this population.

  9. Photoscanning of the Spleen Using Heat-Treated Cr51-Labelled Erythrocytes in Congenital Haemolytic Anaemias

    International Nuclear Information System (INIS)

    The delineation of the spleen by photoscanning after the intravenous injection of heat-treated Cr51-labelled erythrocytes is valuable when investigating congenital haemolytic anaemias, especially thalassaemia, a disease which is recognized as one of the most important public health problems in Greece. Heat-treated Cr51-labelled erythrocytes were prepared as follows: blood was taken from the subject by venepuncture and delivered into a sterile bottle containing acid-citrate-dextrose. The red cells were separated by centrifugation and the plasma discarded. 50 - 150 μc Cr51-chromate was added to the red cells and the mixture allowed to stand for 30 min at room temperature. The labelled cells were washed once with saline and re-suspended in saline. The suspension was heated at 49.5°C for one hour. The heated cells were washed once with saline and re-suspended in saline. The suspension was then injected intravenously into the subject. Scanning was performed one hour later. Cases of thalassaemia major, sickle cell haemoglobin/thalassaemia and thalassaemia trait have been investigated by this method. All the cases studied, with the exception of one carrier of thalassaemia trait, whose spleen was not palpable, showed varying degrees of splenomegaly. The size and configuration of the spleen could be well demonstrated. A constant finding in spleen scans on patients with congenital haemolytic anaemia, not observed in scans on normal subjects, was the presence of regions of lower average radioactivity throughout the organ. The interpretation of this finding is discussed. (author)

  10. Erythrokinetics, ferrokinetics and red cell survival in sickle cell anaemia under subtropical climatic conditions

    International Nuclear Information System (INIS)

    Ferrokinetic parameters were evaluated with 59Fe and red-cell survival with 51Cr by classical techniques in a total of 17 patients with sickle-cell disease. The mean plasma 59Fe half-disappearance time in these patients was 29.5 min as compared with a normal value of 92 min, and the t1/2 51Cr 8.0 days as compared with a normal value of 26.0 days. The mean red-cell iron turnover rate was elevated to 9 times normal. The increased destruction of red cells appeared to take place predominantly, though not entirely, in the spleen. Eight of the 17 patients studied were identified as having intercurrent complications, but these did not significantly affect the results of the investigations. A group of 5 boys in whom the red-cell iron turnover rate was elevated to a lesser degree than in the other patients were subjected to more detailed studies of plasma 59Fe clearance with particular reference to ineffective erythropoiesis. In these patients, the plasma 59Fe clearance curves showed precocious humps characteristic of ineffective erythropoiesis. Detailed analysis of the results indicated ineffective erythropoiesis corresponding to 3.6, 16.0, 22.6, 32.0 and 50.0 % of the iron initially taken up by the bone marrow. It is concluded that while the anaemia in most patients with sickle-cell disease is mainly due to shortened survival of the circulating red cells, with increased destruction of red cells in the spleen, ineffective erythropoiesis may none the less be an important factor determining the actual degree of this anaemia

    2014-12-01

    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.

    A 64-year-old farmer developed aplastic anaemia after exposure to 2-methyl-4-chlorphenoxyactic acid while spraying weed killer. Muscular weakness, haemorrhagic gastritis and slight signs of liver damage occurred at the same time. All these symptoms, including blood dyscrasia , are consistent with those described as toxic effects of chlorphenoxyacetic acids in animal experiments. A causal relationship between aplastic anaemia and the 2-methyl-4-chlorphenoxyacetic acid thus seems probable. The anaemia was reversible, but the case serves as a warning that careful safety measures are required during the use of chlorphenoxyacetic acids and related compounds. PMID:804793

    Full Text Available Anaemia is a relatively common finding in HIV-positive patients, with rates (among females as high as 37%, compared with their HIV negative counterparts (17%. Anaemia of chronic disease plays a very important role in this population group, and is estimated to occur in 18 - 95% of cases. For this reason, it is imperative to distinguish this condition from other underlying or concurrent causes of anaemia that may warrant treatment. This clinical case illustrates the value of critically evaluating the parameters of a full blood count and haematinic screen, to so determine which patients warrant further workup.

    1983-05-01

    Computed tomography of the upper abdomen and of the heart was performed in 21 patients with severe anaemia (mean haematocrit value 0.23, mean haemoglobin content 39.6%). Gross morphology of the heart and great vessels (wall thickness, size of the chambers, lumina and walls of the vessels) were visualized in all patients without the use of contrast media. The smallest discernible difference between the normal heart muscle and blood filling its cavities was about 6-8 H and the smallest discernible difference between the aorta and the aortic blood was about 8-10 H (window width 150 H, window level 50 H). There were no CT signs of haemochromatosis of the heart, while CT measurements were highly suggestive of liver haemochromatosis in several cases. Visual evaluation of liver density in comparison to the density of blood in hepatic and portal vessels is misleading.

    S2 is an accessory protein of equine infectious anaemia virus (EIAV), the function of which is unknown. In order to gain insight into the function of S2, the intracellular localization of the protein, its interaction with viral proteins and its incorporation into viral particles have been investigated. Immunolocalization of S2 revealed punctate staining in the cytoplasm and the S2 protein co-precipitated with the EIAV Gag precursor. Despite overexpression of S2 through the use of a codon-optimized sequence, there was no preferential association of S2 with EIAV particles. These data suggest that S2 may function to organize the Gag protein during particle assembly in the cytoplasm but that it is unlikely to be involved in the early stages of the virus life-cycle.

  17. The role of anaemia in the effectivity of radiation treatment of cancer of the collum uteri

    International Nuclear Information System (INIS)

    The role of anaemia is studied in 129 patients with cancer of the collum uteri subjected to combined radiation treatment by comparing data on anaemia and five years survival rates. Since prognosis as well as incidence of anaemia depend on the extend of the disorder the comparison is done for each clinical stage separately. Only in patients found in clinical III b statistical verification (p<0.001) is present witnessing that survival of anaemia patients is shorter than in the rest of the patients. Factors contributing to these differences being discussed a conclusion is drawn that it may be due to a lowered effectivity of the radiation treatment induced by the existing hypoxy. With this regard the relationship is discussed between oxygen tissue diffusion, cellular proliferation of tumors and the effect of ionizing radiation. (author)

  20. Warm Autoimmune Haemolytic Anaemia and autoimmune hepatitis in an asymptomatic carrier of hepatitis B virus

    International Nuclear Information System (INIS)

    Warm antibody autoimmune haemolytic anaemia, a rare disease (0.2-1 per 100,000 populations), is due to the presence of warm agglutinins that react with protein antigens on the surface of red blood cells causing their premature destruction. Here, we present a case report of a 10 year old girl who came with features of haemolytic anaemia and history of blood transfusion since 3 years. On admission, laboratory test revealed that she had autoimmune hepatitis type 1 and was also an asymptomatic carrier of hepatitis B virus with positive HBs Ag. Steroid therapy resulted in clinical and laboratory remission. Direct antiglobulin test was negative after anaemia resolution, hepatitis B virus antigenemia persisted. To our knowledge, warm antibody autoimmune hemolytic anaemia has not previously been described in association with autoimmune hepatitis and asymptomatic carrier state of hepatitis B virus. (author)

    2000-01-01

    As physicians become more aware of the need to treat anaemia in their patients with cancer, they have to consider 2 treatment options: red blood cell transfusion or recombinant human erythropoietin [epoetin alfa; epoetin beta]. Healthcare systems are under increasing pressure to lower costs while maintaining quality of care; therefore, treatment of cancer-related anaemia requires a disease management strategy aimed at achieving optimal clinical and economic outcomes. Although blood transfusio...

    Full Text Available ABSTRACT: BACKGROUND: More than one - third of world’s women are a naemic with majority residing in developing countries and that too in rural areas. The most highly affected population in the decreasing order is pregnant women, school age children, non - pregnant women and preschool children. Nutritional anaemia has recent ly been ranked as the third leading problem among the women of reproductive age group. Most of the studies conducted so far have focused on pregnant ladies only so it was decided to take all the females in the reproductive age group as the study subjects. AIMS: To find out the prevalence of nutritional anaemia among married females of reproductive age group i.e., 15 - 49 years of age in a rural area of Jammu District. SETTINGS AND DESIGN : Across - sectional study was undertaken in rural settings. METHODS AND M ATERIAL: House to house visits were made and288married females in the reproductive age group were interviewed and their blood samples were taken for necessary haematological investigations which were done at GMC Jammu. STATISTICAL ANALYSIS : Percentages an d chi - square test . RESULTS AND CONCLUSION : More than 90% of the females were suffering from anaemia. Majority of them were having microcytic hypochromic blood picture. More than 50% of the subjects were having moderate anaemia as per WHO classification. Nu tritional anaemia was seen in 70.47% of the study subjects while the remaining females were having either no anaemia or anaemia due to other medical reasons. The prevalence of nutritional anaemia was even more among pregnant and lactating females and this finding was found to be statistically significant.

    Full Text Available The association of anaemia with intestinal schistosomiasis and hookworm infections are poorly explored in populations that are not limited to children or pregnant women.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.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.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.

    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.

    Full Text Available Introduction: Anaemia continues to be a major public health nutritional problem in India, and has adverse health and economic implications. Objective: The objective of the study was to assess the prevalence of anaemia among different physiological groups in the state of Maharashtra. Methodology: A community based cross-sectional study adopting multistage stratified random sampling procedure was carried out in rural Maharashtra. Information of socio-demographic particulars was collected with pretested questionnaire. A finger prick blood sample of 20 µL was collected from the subjects. Haemoglobin was estimated using cyanmethemoglobin method. Results: The overall prevalence of anaemia was 59%, 61%, 76% and 73% among pre-school children, adolescent girls, pregnant women and lactating mothers, respectively. Logistic regression analysis revealed that the risk of anaemia was two times higher among pregnant and lactating women and among the subjects belonged to scheduled caste and scheduled tribe communities. Conclusion: Anaemia is a severe public health problem among pre-school children and women of different physiological groups in rural Maharashtra. Therefore, there is a need to strengthen the existing national nutritional anaemia control programme and the community is encouraged to consume iron rich foods through health and nutrition education and information, education and communication (IEC activities.

    Full Text Available Abstract Background There is a relative lack of recent information about late post kidney transplantation anaemia (PTA, especially in the developing countries; data are scarce about the prevalence and risk factors of PTA. Sudan was a leading country in Africa and Arab world in kidney transplantation. The first kidney transplantation in Sudan was in 1973. Methods This is a cross-sectional hospital analytic study enrolling all kidney transplanted recipients following in the transplant referral clinics at Ahmed Gassim, Selma and Ibn Sina Hospitals, Khartoum/Sudan, in the period from 1/8/2010 to 1/9/2010, clinical and laboratory data were obtained from 114 patients, anaemia was defined as Hb levels of Results The study showed that 39.5% of the patients were anaemic. Univariate analysis showed that late PTA is significantly associated with not using Erythropoietin (EPO in the pre-transplant period (p = Conclusion The study concluded that late PTA is common and under recognized. Risk factors for late PTA include renal dysfunction, history of rejection, longer duration of transplantation and not using EPO in the pre-transplant period. Renal dysfunction and not using EPO in the pre-transplant period are major predictors of late PTA.

  16. Blood thixotropy in patients with sickle cell anaemia: role of haematocrit and red blood cell rheological properties.

    Directory of Open Access Journals (Sweden)

    Jens Vent-Schmidt

    Full Text Available We compared the blood thixotropic/shear-thinning properties and the red blood cells' (RBC rheological properties between a group of patients with sickle cell anaemia (SS and healthy individuals (AA. Blood thixotropy was determined by measuring blood viscosity with a capillary viscometer using a "loop" protocol: the shear rate started at 1 s-1 and increased progressively to 922 s-1 and then re-decreased to the initial shear rate. Measurements were performed at native haematocrit for the two groups and at 25% and 40% haematocrit for the AA and SS individuals, respectively. RBC deformability was determined by ektacytometry and RBC aggregation properties by laser backscatter versus time. AA at native haematocrit had higher blood thixotropic index than SS at native haematocrit and AA at 25% haematocrit. At 40% haematocrit, SS had higher blood thixotropic index than AA. While RBC deformability and aggregation were lower in SS than in AA, the strength of RBC aggregates was higher in the former population. Our results showed that 1 anaemia is the main modulator of blood thixtropy and 2 the low RBC deformability and high RBC aggregates strength cause higher blood thixotropy in SS patients than in AA individuals at 40% haematocrit, which could impact blood flow in certain vascular compartments.

    Monitoring an epidemic of an emerging vector-borne disease can be problematic; particularly in a country where vector-borne disease has previously had minimal impact on livestock. This paper describes methods of past and current surveillance of the Theileria-associated bovine anaemia (Ikeda; TABA) epidemic in New Zealand, and the resulting inferences made. Over the three year period of the TABA epidemic a portfolio of surveillance methods has been used: case reporting (with subsidised PCR testing), syndromic surveillance, sentinel surveillance, testing convenience samples for herd infection, as well as specific active surveillance initiatives to understand the tick vector distribution. Surveillance data have shown that the number of affected cattle herds has continued to increase over time with seasonal peaks in spring and autumn coinciding with peak activity of nymph and adult ticks respectively. In spring 2014, the epidemic extended south into areas that were previously considered to be unsuitable for the tick vector. As a result a survey was initiated that showed that ticks were present in areas outside of the known distribution. Testing pooled blood samples from cattle herds across New Zealand showed there still remained a significant percentage of herds where only non-Ikeda type infections were present, indicating that these herds were at risk of future TABA (Ikeda) outbreaks. For some regions there had been a noticeable increase in the percentage of herds infected, yet with only a small increase in the number of outbreaks compared with the previous year. Thus, outbreaks had either gone unobserved or had not been confirmed by testing. In these regions extensive low-input beef farming could explain the non-detection observed. There was a close relationship between the number of syndromic reports of anaemia and the number of confirmed cases of TABA (Ikeda), (P<0.01, adjusted R-squared=0.74). Active monitoring of the epidemic for a three year period has provided

  18. Iron deficiency anaemia -a risk factor for febrile seizures in children

    International Nuclear Information System (INIS)

    Background: Iron deficiency anaemia and febrile seizures are two common diseases in children worldwide as well as in our country. Iron insufficiency is known to cause neurological symptoms like behavioural changes, poor attention span and learning deficits in children. Therefore, it may also be associated with other neurological disturbances like febrile seizures in children. Objective of our case-control study was to find association between iron deficiency anaemia and febrile seizures in children. Methods: This multicentre study was conducted in Department of Paediatrics HIT Hospital Taxila Cantt, Department of Paediatrics CMH Mangla and Department of Paediatrics POF Hospital Wah Cantt, from June 2008 to June 2010. Three hundred and ten children aged between 6 months to 6 years were included in the study. One hundred and fifty-seven children who presented with febrile seizures were our cases, while, 153 children who presented with febrile illnesses without seizures were recruited as controls. All patients were assessed for iron deficiency anaemia by measuring haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration (MCHC) and Mean Corpuscular Volume (MCV). Patients with iron deficiency anaemia amongst controls and cases were documented. Percentages and Odds ratio were derived from the collected data. Results: 31.85% of cases (50 out of 157) had iron deficiency anaemia whereas, 19.6% of controls (30 out of 153) were found to have iron deficiency anaemia as revealed by low levels of haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration and Mean Corpuscular Volume. Odds ratio was 1.93. Conclusion: Patients with febrile seizures are 1.93 times more likely to have iron deficiency anaemia compared to febrile patients without seizures. (author)

  19. Anaemia and other blood diseases induced by radiation

    International Nuclear Information System (INIS)

    The growing interest in the effects of radiation on blood formation is explained not only by the fact that haemopoietic tissue can be damaged in the event of accidents, but also by the fact that depression of medullary haemopoiesis is often a limiting factor in radiotherapy for various malignant diseases, in particular leukosis. The degree of cell alteration in the peripheral blood resulting from different types of exposure to ionizing radiation depends to a large extent on the lifetime of the cells since in irradiation it is primarily the balance between utilization and production of new cells that is disrupted. In animals that survive exposure to lethal doses of radiation a notable drop in the number of erythrocytes has been observed between the 10th and 30th days after irradiation. The most pronounced anaemia usually appears between the 15th and 20th days. In animals that do not survive a significant drop in the number of erythrocytes takes place the day before or the day on which death occurs. The decrease in the number of red blood cells is due mainly to a drop in their production, to increased destruction of erythrocytes and to haemorrhage

  20. Screening for fetal and genetic abnormalities.

    1991-09-01

    Screening for genetic abnormalities is an integral part of obstetrics. Prior to initiating screening, however, several prerequisites must be met: (i) capacity to alter clinical management, (ii) cost effectiveness, (iii) reliable means (usually assays) of assessment, and (iv) capacity to handle problems. In all pregnancies one should determine in systematic fashion whether family history places a pregnant woman at increased risk over the background risk of 2-3% congenital anomalies. All women over age 35 years at delivery should be offered prenatal cytogenetic testing, and women of all ages should be offered maternal serum alpha-fetoprotein screening for neural tube defects. Screening ostensibly normal populations is appropriate in certain ethnic groups to determine heterozygosity for selected disorders: Blacks for sickle-cell anaemia, Mediterranean people for beta-thalassaemia, Southeast Asians and Filipinos for alpha-thalassaemia, Ashkenazi Jews and perhaps French-Canadians for Tay-Sachs disease. Cystic fibrosis screening (delta F508 mutations) is not currently recommended for the general populations, but should be offered to relatives of an individual having delta F508 cystic fibrosis. Irrespective of the extent of screening programmes for Mendelian traits, the mutant allele will remain in the general population because by far the greatest genetic load lies in clinically normal heterozygotes, affected contributing far less to the load despite the obvious clinical effect.

    Full Text Available BACKGROUND: Adolescence is the formative period of life when the maximum amount of physical, psychological and behavioral changes takes place and this is a vulnerable period in the human life cycle for the development of nutritional anaemia, which has been constantly neglected by public health programs. The prevalence of anaemia is disproportionately high in developing countries than developed countries. It has mainly been ascribed to poverty, inadequate diet, certain diseases, pregnancy and lactation, and poor access to health services in developing countries Prevalence of anaemia in adolescents in India have been reported in limited studies available from 16.25% to 96.5%. Nutritional anaemia constitutes the most important cause of anaemia in adolescents. It is mainly due to deficiency of Iron, Vitamin B12 and Folate. Megaloblastic Anaemia resulting from deficiency of folate and B12 appears to be increasing over the last two decades. AIMS AND OBJECTIVES: 1.To study the types of nutritional anemia in adolescents (10-18 yrs. attending the hospital and correlate severity of nutritional anemia with serum levels of ferritin, Vit B12 & folate. 2. And also to determine demographic, socio-economic & nutritional factors for nutritional anemia in adolescents. STUDY DESIGN: A cross sectional study was conducted in selected sample of 200 subjects. SETTINGS: The study was conducted in the Department of General Medicine, Azeezia Medical College; during November 2011 to April 2013, as a cross-sectional observational study. MATERIALS AND METHODS: Subjects were selected based on the inclusion criteria set and evaluated with aid of laboratory investigation of blood samples collected from subjects. RESULTS AND CONCLUSION: Present study was undertaken to find out etiology and socio-demographic correlates of nutritional anaemia in adolescents. And it was found out that Folate deficiency was the most common followed by Vitamin B12 deficiency & then irons deficiency

    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.

    International Nuclear Information System (INIS)

    Background: Heart Failure (HF) is a common disease with a high mortality rate. Anaemia and renal failure (RF) are often present in patients with HF and associated with worse prognosis. Objective of study was to evaluate the prevalence of anaemia and RF in patients with HF. Methods: Patients admitted in Punjab institute of cardiology Lahore with diagnosis of heart failure were enrolled from February, 2008 to December, 2008. Anaemia was defined as haemoglobin levels <13 mg/dl for men and 12 mg/dl for women. Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Results : Of the 276 patients included in this study, 42.03% (116) had anaemia and 38.40% (106) had moderate to severe renal failure (GFR <60 ml/min). Conclusion: The prevalence of anaemia and renal failure was high in this population and was associated with the severity of the HF (functional classes III and IV). (author)

    International Nuclear Information System (INIS)

    Griscelli's disease is a rare autosomal recessive immunodeficiency syndrome. We report a 7-1/2-month-old white girl who presented with this syndrome, but initially without neurological abnormalities. Initial CT of the brain was normal. Despite haematological remission with chemotherapy, she developed neurological symptoms, progressing to coma. At this time, CT showed areas of coarse calcification in the globi pallidi, left parietal white matter and left brachium pontis. Hypodense areas were present in the genu and posterior limb of the internal capsule on the right side, as well as posterior aspects of both thalami, together with minimal generalised atrophy. MRI revealed areas of increased T2 signal and a focal area of abnormal enhancement in the subcortical white matter. Griscelli's disease should be added to the list of acquired neuroimaging abnormalities in infants. (orig.)

    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.

  8. Successful allogeneic stem cells transplantation in severe aplastic anaemia complicated by dengue fever

    International Nuclear Information System (INIS)

    Aplastic anaemia is characterized by severe compromise of haematopoiesis and hypocellular bone marrow. Haemorrhagic episodes in patients with aplastic anemia occur usually secondary to thrombocytopenia and require frequent support with platelet concentrates and other blood products. Infection with dengue virus (particularly dengue sero type-2 of South Asian genotype) is associated with dengue haemorrhagic fever. Dengue infection further worsens the disease process in patients with aplastic anaemia due to uncontrolled haemorrhagic diathesis and major organ failure, which may prove fatal in these already immunocompromised patients, if not treated in time. Recent epidemics of dengue haemorrhagic fever has not only affected the southern region of our country but also spread to other areas of the country. With this background, we report a case of aplastic anaemia complicated by dengue haemorrhagic fever who achieved successful engraftment after allogeneic stem cell transplantation from sibling brother and is having normal healthy post transplant life.

    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.

  12. Study of trypanosome and anaemia indicators during the eradication of tsetse flies from Unguja island, United Republic of Tanzania

    International Nuclear Information System (INIS)

    A large number of cattle has been monitored regularly during a ten-year period on Unguja island, United Republic of Tanzania, as part of a number of consecutive programmes to initially control and eventually eradicate tsetse and trypanosomosis. Haematological and parasitological results were used among others to monitor and adjust the control and eradication programmes from 1988 to 1997. A Geographic Information System (GIS) was applied to the data set to assess changes of animal health parameters in time and space. Analysis of the data showed significant changes over the years in infection status and degree of anaemia. Moreover, differences in health status of cattle populations between adjacent geographic areas were detected. Regular monitoring using standardized protocols by a multidisciplinary team resulted eventually in the eradication of tsetse flies from the island. (author)

  13. Selective breeding can increase resistance of Atlantic salmon to furunculosis, infectious salmon anaemia and infectious pancreatic necrosis

    2008-01-01

    We reasoned that by challenging large numbers of Atlantic salmon families with the causative agents of furunculosis, infectious salmon anaemia (ISA) and infectious pancreatic necrosis (IPN), we could show unequivocally that resistance to these diseases expresses moderate-to-high levels of additive...... genetic variation, and that the resistances are weakly correlated genetically. We tested this reasoning by challenging Atlantic salmon from 920 (approximately) full-sib families with the causative agents of furunculosis and ISA, and fish from 265 of these families with the causative agent of IPN. Additive...... genetic variation and genetic correlations were estimated by fitting a threshold liability model to the resistances assessed as binary traits. Resistance to furunculosis, ISA and IPN was moderate â€"to highly heritable. The marginal posterior means for heritability on the underlying liability scale were 0...

    Full Text Available Background. Iron status in patients with sickle cell anaemia is a matter of continuing investigation. Objective. This paper aims to determine the serum iron status of under-five, sickle cell anaemia patients. Methods. The study spanned from December 2009 to February 2010 at the Consultant Outpatient Clinics involving 97 HbSS subjects and 97 age- and sex-matched HbAA controls. Biochemical iron status was assayed in subjects and controls. Results. Age range of the children was seven months to five years, with a mean of 30.6 (±15.97 months. Irrespective of gender, mean serum iron values were higher in HbAA controls than their HbSS counterparts but the observed difference was not significant ( and 0.111, resp.. The mean total iron binding capacity values of males and females were also not significantly different for sickle cell anaemia subjects and controls (. Males and females with HbAA had significantly lower serum ferritin when compared with their HbSS counterparts. Irrespective of gender, mean transferrin saturation was lower in HbSS subjects but the difference was not statistically significant (. Conclusion. Children with sickle cell anaemia have higher serum ferritin than controls, implying relatively higher iron content in the reticuloendothelial cells.

    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.

Conclusion: The informative & educable intervention definitely has a positive effect on awareness levels which would eventually encourage expansion of knowledge & positive health habits.

  3. HIF prolyl hydroxylase inhibitors for the treatment of renal anaemia and beyond.

    2016-03-01

    Small-molecule stabilizers of hypoxia inducible factor (HIF) are being developed for the treatment of renal anaemia. These molecules inhibit prolyl hydroxylase domain-containing (PHD) enzymes, resulting in HIF activation and increased production of erythropoietin. Currently, renal anaemia is treated with recombinant human erythropoietin or related analogues, referred to as conventional erythropoiesis stimulating agents (ESAs). Advantages of PHD enzyme inhibitors over conventional ESAs include their oral administration and their simpler - and potentially cheaper - production. Importantly, inhibition of PHD enzymes is likely to have a range of consequences other than increasing levels of erythropoietin, and these effects could be beneficial - for instance by reducing the need for parenteral iron - but might in some instances be harmful. Several companies are currently testing PHD enzyme inhibitors in patients with renal anaemia and have reported clear evidence of efficacy without serious safety concerns. A central question that current studies are beginning to address is whether using PHD enzyme inhibitors will influence hard end points, including mortality and the rate of cardiovascular events. In terms of approaches to therapy, the exquisite specificity of conventional ESAs is a striking contrast to the pleiotropic effects of activating HIF. Excitingly, PHD inhibitors could also be useful for conditions besides renal anaemia, such as protection from ischaemic injury. PMID:26656456

    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.

    Inequitable access to healthcare has a profound impact on the health of marginalised groups that typically suffer an excess burden of infectious disease morbidity and mortality. The Yanomami are traditionally semi-nomadic people living in widely dispersed communities in Amazonian Venezuela and Brazil. Only communities living in the vicinity of a health post have relatively constant access to healthcare. To monitor the improvement in the development of Yanomami healthcare a cross-sectional survey of 183 individuals was conducted to investigate malaria and anaemia prevalence in communities with constant and intermittent access to healthcare. Demographic and clinical data were collected. Malaria was diagnosed by microscopy and haemoglobin concentration by HemoCue. Prevalence of malaria, anaemia, splenomegaly, fever and diarrhoea were all significantly higher in communities with intermittent access to healthcare (anaemia 80.8% vs. 53.6%, P<0.001; malaria 18.2% vs. 6.0%, P=0.013; splenomegaly 85.4% vs.12.5%, P<0.001; fever 50.5% vs. 28.6%, P=0.003; diarrhoea 30.3% vs.10.7% P=0.001). Haemoglobin level (10.0 g/dl vs. 11.5 g/dl) was significantly associated with access to healthcare when controlling for age, sex, malaria and splenomegaly (P=0.01). These findings indicate a heavy burden of anaemia in both areas and the need for interventions against anaemia and malaria, along with more frequent medical visits to remote areas. PMID:18405929

    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 Fanconi anaemia (FA is a rare genetic chromosomal instability syndrome caused by impairment of DNA repair and reactive oxygen species (ROS imbalance. This disease is also related to bone marrow failure and cancer. Treatment of these complications with radiation and alkylating agents may enhance chromosomal breakage. We have evaluated the effect of amifostine (AMF on basal and mitomycin C (MMC-induced chromosomal breakage in FA blood cells using the micronucleus assay. The basal micronuclei count was higher among FA patients than healthy subjects. Pre-treatment with AMF significantly inhibited micronucleation induced by MMC in healthy subjects (23.4 ± 4.0 – MMC vs 12.3 ± 2.9 – AMF →MMC MN/1000CB, p < 0.01, one way ANOVA as well as in FA patients (80.0 ± 5.8 – MMC vs 40.1 ± 5.8 – AMF →MMC MN/1000CB, p < 0.01, ANOVA. Release of ROS by peripheral blood mononuclear cells treated with AMF →MMC and measured by chemoluminometry showed that AMF-protection was statistically higher among FA patients than in healthy individuals. Based on these results we suggest that AMF prevents chromosomal breakage induced by MMC, probably by its antioxidant effect.

  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.

    2011-01-01

    Hepatitis-associated aplastic anaemia (HAAA) is an uncommon but distinct variant of aplastic anaemia in which pancytopenia and bone marrow failure appears 2-3 months after an acute attack of hepatitis. Although bilateral vision loss may rarely be the initial presentation of aplastic anaemia, no such report is known in HAAA. Here the authors report such a case presenting with large premacular subhyaloid haemorrhages secondary to severe anaemia and thrombocytopenia. Anaemic hypoxic damage to the vessel wall together with increased cardiac output and low platelet counts are interacting causal factors in the development of bleeding. Though these haemorrhages are benign and usually improve spontaneously, the presence of blood may cause permanent macular changes before it resolves. Posterior hyaloidotomy enabled rapid resolution of premacular subhyaloid haemorrhage thereby restoring vision and preventing need for vitreo-retinal surgery. These patients should be advised to refrain from valsalva manoeuvres, ocular rubbing and vigorous exercise to prevent ocular morbidity. PMID:22674943

    Full Text Available Abstract Background Hyperlactataemia is often associated with a poor outcome in severe malaria in African children. To unravel the complex pathophysiology of this condition the relationship between plasma lactate levels, parasite density, pro- and anti-inflammatory cytokines, and haemozoin-containing leucocytes was studied in children with severe falciparum malarial anaemia. Methods Twenty-six children with a primary diagnosis of severe malarial anaemia with any asexual Plasmodium falciparum parasite density and Hb Results Parasite density was associated with lactate levels on admission (r = 0.56, P r = 0.60, P = 0.003 and r = -0.46, P = 0.02, respectively. These associations were not found in controls with uncomplicated malarial anaemia. Conclusion These data suggest that blood stage parasites, haemozoin and low levels of IL-12 may be associated with the development of hyperlactataemia in severe malarial anaemia.

    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

    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.

    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.

    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.

    Coeliac disease (CD) occurs in individuals sensitive to gluten protein contained in wheat products. It affects at least 1:100 children and may present with extra-intestinal manifestations such as iron deficiency anaemia, short stature and delay in puberty. A case of severe iron deficiency anaemia as a manifestation of CD is described here. There is a need to raise awareness among health professionals about CD and its extra-intestinal presentations. Suspicion of CD should lead to antibody screening tests and positive results should be followed by an intestinal biopsy for a definitive diagnosis. Involvement of a paediatric dietitian is vital in the management of CD and lifelong adherence to a gluten-free diet is necessary. We hope this article leaves the reader with a heightened awareness about CD and will lead to appropriate early referral to the paediatric services. PMID:20518373

In thalassaemic children the calculated parameters denote that the shorting of the mean cell life is due to early senescence alone, while there is some evidence that in thalassaemic adults additional extracellular destruction mechanisms participate as well. Red cell survival curves from patients with sickle-cell anaemia and s-..beta..-thalassaemia resemble each other, while their parameters indicate an initial rapid loss of radioactivity, early senescence and the presence of extracellular red cell destruction factors.

    A seven-year-old flat-coated retriever presented with a history of lethargy, dyspnoea and inappetence of several days' duration. Clinical examination revealed pale mucous membranes and tachypnoea, and haematology demonstrated marked autoagglutination. Thoracic radiographs revealed an increased opacity in the perihilar region. The owners declined further evaluation and the dog was treated symptomatically with immunosuppressive doses of prednisolone and azathioprine. The dog's demeanour improved, although it was eventually euthanased seven weeks later because of dysphagia and worsening dyspnoea. Postmortem examination revealed a widespread, poorly differentiated sarcoma involving the lungs, pericardium, thoracic lymph nodes and spleen. Immune-mediated haemolytic anaemia is a well recognised condition in dogs and is occasionally associated with neoplastic conditions. This is the first case report to describe immune-mediated haemolytic anaemia associated with a diffuse, poorly differentiated sarcoma. PMID:14756205

    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.

    Malaria and anaemia which jointly account for high proportion of morbidity and mortality among young children in developing countries have been individually studied using binary regression model. We adopt geoadditive latent variable model for binary/ordinal indicators to analyze the influence of variables of different types on the morbidity among young children in Nigeria. Latent variable models allow for the analysis of multidimensional response variables that reveal the indicator's underlying relationship that are caused by the latent variables. We extend the structural model to a semi-parametric geoadditive model in order to quantify the joint spatial structure of morbidity from malaria and anaemia. Findings revealed substantial geographical variations and the generated maps can guide policy makers and donors on how to prudently utilize the scarce resources for designing more cost-effective interventions.

    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.

    AIM: This report gives a comprehensive overview of ultrasonography of splenic abnormalities. Certain ultrasonic features are also discussed with pathologic correlation.METHODS: We review the typical ultrasonic characteristics of a wide range of splenic lesions, illustrating them with images obtained in our institution from 2000 to 2003.One hundred and three patients (47 men, 56 women),with a mean age of 54 years (range 9-92 years), were found to have an abnormal ultrasonic pattern of spleen.RESULTS: We describe the ultrasonic features of various splenic lesions such as accessory spleen, splenomegaly,cysts, cavernous hemangiomas, lymphomas, abscesses,metastatic tumors, splenic infarctions, hematomas, and rupture, based on traditional gray-scale and color Doppler sonography.CONCLUSION: Ultrasound is a widely available, noninvasive,and useful means of diagnosing splenic abnormalities. A combination of ultrasonic characteristics and clinical data may provide an accurate diagnosis. If the US appearance alone is not enough, US may also be used to guide biopsy of suspicious lesions.

    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 this pooling project, we examined the combined impact of baseline haemoglobin levels and existing CVD on all-cause and CVD mortality in people with diabetes. We draw comparison of these effects with those apparent in diabetes-free individuals. METHODS/PRINCIPAL FINDINGS: A ...

    Full Text Available Anaemia is a global public health problem particularly in developing countries. A major contributory factor to maternal and fetal mortality and morbidity. AIM AND OBJECTIVES : To find the prevalence and seve rity of anaemia and evaluate the multiple causal factors among pregnant women. MATERIALS AND METHODS : A cross sectional study was conducted in pregnant women attending outpatient department of Obstetrics and Gynaecology from J uly 1 st 2013 to J une 30 th 2015 Rajah Muthiah Medical College and Hospital , a tertiary care rural hospital in C hidambaram . A pre - designed Performa was utilized to obtain relevant information about demographic and patients’ obstetric characteristics. They were screened for anaemia using cyanmethemoglobin method during their first antenatal visit. RESULTS : The prevalence of anaemia was found to be (1202/1434 83.8% of which mild 27.2%, moderate 60.3% and severe was 12.5% ( A ccording to WHO criteria based on Hb level. Majority were between 20 - 25yrs of age (87861.2% in third trimester (95666.7% were unbooked (91263.5%, illiterate (67747.3% and belonged to low socioeconomic class (109276.1%. Multiparity (92864.7%, pregnancy spacing interval less than 1yr (38841.8%, poor nutrition (6724 6.8% were the most common risk factors. CONCLUSION : In our study, the prevalence rate is still very high in spite of the various preventive strategies as awareness is less among the population . Major factors responsible were multiparity, illiteracy, povert y, late antenatal booking, inadequate spacing between pregnancies. Adequate antenatal care and proper education helps to increase the awareness.

  17. Giant Brunner’s gland adenoma as an unusual cause of anaemia: report of a case

    International Nuclear Information System (INIS)

    Brunner’s gland adenoma (BGA) is a rare benign duodenal tumour proliferating from Brunner’s glands. Here, we present a giant BGA leading to anaemia, with its clinical, endoscopic, radiological, surgical and pathological findings. A 48-year-old Turkish man complained of a six months history of vague epigastric discomfort, loss of appetite and nausea after meals without vomiting. The physical examination had no unremarkable finding. Laboratory findings, including liver function tests, were within normal limits except a hypochromic, microcytic anaemia. The upper gastrointestinal endoscopic examination revealed a lobulated, red, polypoid tumour with a smooth surface covered with normal mucosa. The tumour was located on the anterior surface of duodenal bulb and had a wide base measuring 3.5 × 4 cm in size. Endoscopic ultrasonography revealed a submucosal polypoid mass located at the anterior surface of duodenal bulb. The endoscopic excision was tried but was not successful. The patient was operated and transduodenal polypectomy was done. The postoperative period was uneventful and the pathologic diagnosis was assessed as Brunner’s gland adenoma. During the follow-up period, the endoscopic examination was normal at 12th month postoperatively. BGA is a rare benign cause of anaemia that can be treated with excellent results

    1997-09-01

    In two unrelated Spanish males with glucose-6-phosphate dehydrogenase (G6PD) deficiency and haemolytic anaemia, and two different novel point mutations in the G6PD gene, have been identified. A C to T transition at nucleotide 406 resulting in a (136) Arg to Cys substitution and a C to G transition at nucleotide 1155 resulting in a (385) Cys to Trp substitution. These two molecular defects have not been described before and are designated G6PD Valladolid 406 C-->T and G6PD Madrid 1155 C-->G. In vitro biochemical characterization of both mutant enzymes showed important differences in their molecular properties according to their different clinical behaviour. In G6PD Valladolid, the mutation of which is located in exon 5, the normal in vitro heat stability may explain its mild clinical expression (low-grade haemolysis interrupted by an acute haemolytic crisis at age 70). In G6PD Madrid, the mutation, located in exon 10, results in a deficient variant associated with neonatal jaundice and life-long chronic nonspherocytic haemolytic anaemia (CNSHA). This finding further emphasizes the importance of this specific region of the G6PD gene in the stabilization of the G6PD molecule. Putative relationships between these single point mutations and the molecular properties of the mutant enzymes are also discussed. PMID:9332310

    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

    Full Text Available Background: Anaemia in pregnancy is a global public health challenge. It is the commonest medical disorder of pregnancy and a major cause of morbidity and mortality in most developing countries. Aim: This study aimed at assessing the prevalence of anaemia in pregnancy and to identify the confounding socio-demographic factors. Methods: This is a cross-sectional descriptive study designed to determine the socio-demographic characteristics and prevalence of anaemia among pregnant women at their booking antenatal visit in a teaching hospital in South-western Nigeria. Pregnant women were enrolled for the study by consecutive sampling method at their first antenatal visit and the packed cell volume (PCV was used to assess level of anaemia. Socio-demographic information was obtained from the case records of the enrolled women. Results: One hundred and thirty-eight (27.6% of the 500 enrolled women were found to be anaemic at the time of antenatal booking. Anaemia were more prevalent among primigravidae (33.9% than the multigravidae (25.3%, although this difference was not statistically significant (P=0.079. Anaemia was higher among women with no formal education, those unemployed, single mothers and women with sickle cell traits. Conclusion: Anaemia in pregnancy remains a major health challenge in Nigeria with primigravidae identified as being those at most risk. So also are pregnant teenagers and women that book late for antenatal care (ANC. It is therefore important to educate women on early ANC booking and the need for compliance with prescribed medications in pregnancy.

    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 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.

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

    Directory of Open Access Journals (Sweden)

    2008-03-01

    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.

    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.

    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.

    The importance and variability of pre-operative anaemia in cardiac surgical patients across the UK is not known, and there is debate about its association with patient outcomes. The Association of Cardiothoracic Anaesthetists carried out its first national audit on anaemia and transfusion, and analysed data from 19,033 patients operated on in 12 cardiac surgical centres between 2010 and 2012; 5895 (31%) had pre-operative anaemia. Centre-specific prevalence of anaemia varied from 23% to 45%; anaemia was associated with older patients, diabetes and surgical risk (EuroSCORE). Nevertheless, controlling for these factors, regional variation remained an independent effect (p treatment before cardiac surgery is required; these data will assist in designing such trials.

    Full Text Available Aim. To investigate the efficacy of carbamazepine as adjuvant drug therapy in acute paranoid psychosis with associated EEG abnormalities, compared to sole antipsychotic treatment. Methods. Eleven medication-naive patients diagnosed with acute paranoid psychosis with associated EEG abnormalities were divided into two treatment groups: sole fluphenazine group, with flexible dosing of 5-10 mg/day (n=6, and carbamazepine group (n=5 with the addition of carbamazepine (600 mg/day to fluphenazine treatment. Clinical Global Impression (CGI, Brief Psychiatric Rating Scale (BPRS, Scale for the Assessment of Negative Symptoms (SANS, and EEG were assessed on the baseline and after 6 weeks of treatment. Paired and two-tailed t-tests were used for statistical significance. Results. All the patients showed significant improvement of mental state after 6 weeks of treatment with no significant differences in CGI, BPRS, and total SANS scores in relation to the therapy with carbamazepine. Nevertheless, after 6 weeks of the treatment, EEG findings were significantly better in carbamazepine group, in relation to the findings from the onset of the treatment, as well as in comparison to sole fluphenazine group. Conclusion. Although carbamazepine stabilized abnormal brain electrical activities it seemed that the associated EEG abnormalities were not significant for acute psychosis observed. These preliminary results suggested that there was no convincing evidence that carbamazepine was efficient as the augmentation of antipsychotic treatment for patients with both acute paranoid psychosis and EEG abnormalities.

    Full Text Available Background: Sickle cell anemiais a genetic disorder that is characterized by chronic anemia and oxidative stress. AIM: This study was investigated to evaluate the level of antioxidant vitamins C and E, and glycatedhaemoglobin in patients with homozygous sickle cell disorders (HbSS in steady state and HbSS in crisis and normal healthy individuals (HbAA. Material and Methods: 100 sickle cell patients aged 5-30 years were included in this study while 100 normal healthy individuals served as the control. Also 30 sickle cell patients in crisis was involved. Results: This results obtained showed that the level of vitamins C and E were significantly depleted in sickle cell disease when compared with healthy individuals at p<0.05. In the same vein, the level of glycatedhaemoglobin was decreased in sickle cell disease when compared with normal healthy control. Also the levels of vitamins and glycatedhaemoglobin were significantly decreased in sickle cell crises (P<0.05. Conclusion: This shows that depleted antioxidant vitamins could be an important factor in sickle cell crisis. Hence, supplementation of sickle cell patients with vitamins can improve their health.

    Full Text Available 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.

  19. The role of host nutrition in the pathogensis of liver fluke anaemia

    International Nuclear Information System (INIS)

    Although it is widely accepted that the course of many helminth diseases of sheep is determined by two main variables, namely the level of infection and the host's nutritional status, the importance of the latter in the pathogenesis of ovine fascioliasis remains to be determined. The results of the experiment described here demonstrate that dietary quality has no significant effect upon fluke establishment but profoundly influences the severity of the disease as evidenced by the more rapid development of anaemia and by earlier mortalities among sheep restricted to a maintenance ration (containing about 6% crude protein) compared with similarly infected animals receiving a diet commensurate with growth (13% crude protein). Concurrent measurements of blood volume and of red cell turnover using radioisotopic methods revealed that in all animals the anaemia was caused by a combination of haemodilution, intra-hepatic and biliary haemorrhage, but that the earlier and more severe disturbances in protein-restricted sheep reflected the earlier development of these changes in association with a faster rate of fluke migration, and was ultimately complicated by impaired erythropoiesis arising from iron deficiency.

  20. Marrow uptake index (MUI): A quantitative scintigraphic study of bone marrow in aplastic anaemia

    International Nuclear Information System (INIS)

    Aplastic anaemia affects the entire bone marrow. This prospective study was undertaken to develop and standardise a new nuclear medicine technique called 'dynamic bone marrow imaging'. Eleven patients and ten controls were studied. Serial images of the pelvis were obtained in frame mode following intravenous injection of 185-370 mBq of 99mTc S. Colloid, and an index, called the bone marrow uptake index was calculated by taking into consideration the time activity curve obtained over the iliac crest. This was followed by static imaging of the entire bone marrow in all cases. It was possible to obtain excellent information regarding topographic distribution of bone marrow as well as detect early changes in bone marrow function following treatment. An attempt was also made to correlate bone marrow cellularity as obtained by bone marrow biopsy with results of dynamic bone marrow scintigraphy. On the basis of the encouraging results obtained in the present study, the authors feel that dynamic bone marrow imaging is an excellent technique for the objective evaluation of bone marrow in aplastic anaemia. 20 refs.; 4 figs.; 5 tabs

    Kuliszkiewicz-Janus, Małgorzata; Zimny, Anna

    2003-11-01

    Glucose-6-phosphate dehydrogenase (G6PD) is one of the most important cytoprotective enzymes for oxidative stress. The WHO classification of G6PD deficiency, based on enzyme activity and clinical significance, distinguishes five variants. Chronic haemolytic process is rare and the main factors causing haemolysis are: infections, substances derived from plants, drugs with high oxidation-reduction potential, stress, ketoacidosis in diabetes and surgery operations. We report two cases of women belonging to the class 3 of the WHO classification in whom haemolysis occured during pregnancy. One of the patients developed two incidents of haemolytic anaemia. The cause of the first episode, nine months before pregnancy, was probably infection of the urinary tract caused by Escherichia coli, but the influence of the drugs also cannot be excluded. Because of the genetic background of this enzymopathy we also examined members of the patients, families but did not find any evidence of G6PD deficiency among them. The reported cases indicate that haemolytic anaemia caused by G6PD deficiency may occur during pregnancy what can lead to many not only haematological but also serious obstetrical complications such as infertility, fetus malformations and even its death. We also draw attention to several difficulties in diagnosing G6PD deficiency especially during haemolysis. PMID:16737003

    Drug-induced immune haemolytic anaemia is a rare but serious condition. This study investigated the possibility of drug aetiology of immune haemolytic anaemia (IHA) in 134 patients with new onset of IHA who were identified in the Berlin Case-Control Surveillance Study between 2000 and 2009. Single drugs related to IHA in three or more patients and assessed more than once as a certain or probable cause of IHA in a standardized causality assessment included diclofenac, fludarabine, oxaliplatin, ceftriaxone and piperacillin. In a case-control study including all 124 IHA cases developed in outpatient care and 731 controls, significantly increased odds ratios (OR) were observed for beta-lactam antibiotics (OR=8·8; 95% confidence interval [CI] 3·2-25·2), cotrimoxazole (OR=6·5; CI 1·1-37·9), ciprofloxacin (OR=6·9, CI 1·3-38·5), fludarabine (OR=22·2; CI: 2·8-454·5) and lorazepam (OR=5·3; CI: 1·2-21·2). Excluding new onset cases with a chronic IHA disease course, an increased risk became also apparent for diclofenac with an OR of 3·1 (CI 1·3-7·0). This is the first case-control study investigating drugs as risk factors for IHA. It corroborates an increased risk for several drugs that have been implicated as a cause of IHA in the standardized causality assessment of individual cases. PMID:21749359

    2008-04-01

    Full Text Available Abstract Introduction Angiolipomas are frequently observed benign tumours. They have a typical vascular component and are often located in subcutaneous tissues, and more rarely, in the gastrointestinal tract. Case presentation We report an uncommon case of an angiolipoma found in the lower portion of the small bowel of an 80-year-old man who was undergoing evaluation for chronic anaemia. A standardised diagnostic pathway was followed. Endoscopic and radiological findings were negative. The diagnosis was finally established with the aid of capsule endoscopy. The case we report is the first in the literature of an angiolipoma without specific painful symptoms. In fact, the patient did not complain of abdominal pain or alvus changes, and abdominal examination did not suggest an expansive process. The endoscopic study performed with the capsule identified the lesion as the cause of the ingravescent anaemia. Intra-operative histological examination of the lesion made it possible to avoid a major surgical procedure and assured a short postoperative course for the patient. Conclusion This report focuses on the importance of correct pre- and/or intra-operative histological diagnosis in order to offer the best therapeutic choice. An angiolipoma was suspected in this case, even though they are rarely located in the ileum.

    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.

    2007-03-01

    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 To overcome the defects of common used algorithms based on model for abnormal speech recognition, which existed insufficient training data and difficult to fit each type of abnormal characters, an abnormal speech detection method based on GMM-UBM was proposed in this paper. For compensating the defects of methods based on model which difficult to deal with the diversification speech. Firstly, many normal utterances and unknowing type abnormal utterances came from different speaker, were used to train the GMM-UBM for normal speech and abnormal speech, respectively; secondly, the GMM-UBM obtained by training normal speech and abnormal speech were used to s core for these testing utterances. From the results show that compared with GMM and GMM-SVM methods under 24 Gaussians and the ratio of training speech and testing is 6:4, the correct classification ratio of this proposed have 6.1% and 4.4% improvement, respectively

  7. Dietary Intake of Iron Rich Food and Awareness on Iron Deficiency Anaemia among Female Students in Rawalpindi

    International Nuclear Information System (INIS)

    Objective: To assess the awareness and intake of iron rich diet amongst college girls with a particular focus on the knowledge about the iron deficiency anaemia. Materials and Methods: A cross sectional survey was conducted in Government College for Women Rawalpindi, during September - December 2010. One hundred and thirty five students of intermediate level aged 17-19 years were selected through convenient sampling technique. The sample size was calculated by WHO-sample size calculator, keeping 95 percent Cl, p<0.05 statistically significant, anticipated population proportion of iron deficiency anaemia 35 percent and absolute precision at 0.08. Results: The awareness about iron rich diet and iron deficiency anaemia was satisfactory (86 percent), while poor intake of iron rich diet amongst adolescent college girls (52 percent) was found. About 65 percent of the participants had knowledge about the causes of iron deficiency anaemia (IDA); while 72 percent and 80 percent knew about the prevention and treatment of IDA respectively. Conclusions: Results indicate the gap between knowledge and practices about IDA; it highlights the need of an effective health promotional programme to raise awareness about the significance of iron in young female diet and to highlight the consequences when it is absent.

    2000-12-01

    A prospective study, aimed to investigate the aetiology of an unusual clustering of cases of severe acute haemolytic anaemia affecting a high percentage of the adult population, was carried out in two isolated Yanomamo communities of the Upper Orinoco basin in Venezuela. Twenty-six patients with active or recent episodes of severe haemolysis were evaluated. All of them exhibited massive liver and spleen enlargement and fulfilled the diagnostic criteria of the hyperreactive malarious splenomegaly (HMS) syndrome. In four cases with advanced non-alcohol-related chronic liver disease, hypersplenism, severe haemolytic anaemia and acanthocytosis, the characteristic clinical and laboratory findings of spur cell anaemia were documented. Chronic infection by the HBV and HCV was present in three of them. However, in most of the 22 additional HMS cases, the acute haemolytic condition appeared associated with the occurrence of a cold agglutinin-mediated autoimmune response. The clustering of a significant number of cases of severe acute haemolysis in HMS patients from this small isolated aboriginal community is most unusual, and represents a serious complicating factor for a population already beleaguered by a high prevalence of malaria due to multiresistant strains of Plasmodium falciparum. Moreover, the coexistence of HMS and severe chronic HBV or HCV infection may further aggravate the course of the haemolytic disorder, because of the occurrence of spur cell anaemia. PMID:11114387

  14. Increasing the effectiveness of hyperbaric oxygen in enhancing tumor oxygenation: Effect of perfluorochemical emulsion and moderate anaemia

    International Nuclear Information System (INIS)

    Attempts were made to increase the effectiveness of HBO in overcoming tumor hypoxia. Tumor blood flow and O/sub 2/ content were modified by inducing moderate anaemia and giving a perfluorochemical emulsion (PFC-E). Mice were anaesthetized with Ketamine and Diazepam. The PFC-E, FC-43 (0.35 ml/25 g mouse), given iv 1-2 h before irradiation, produced a favourable effect on regrowth delay in those mice treated with HBO. A 25 Gy dose produced a significantly longer regrowth delay (p<0.01) of 44 days in PFC-treated mice compared with a delay of 29 days for mice treated with HBO alone. O/sub 2/ toxicity was observed in some anesthetized mice, with or without PFC-E. Attempts were made to increase the O/sub 2/ sensitization afforded by FC-43/HBO/anaesthesia. Blood viscosity was reduced by inducing a moderate level of acute anaemia by the administration of a single of acute anaemia by the administration of a single ip injection of Phenylhydrazine HCl (40 mg/kg). This reduced the haematocrit from 42% to 32%. Tumour regrowth delay after 25 Gy was significantly reduced (p<0.02) from 44 to 37.3 days be anaemia. PFC's may prove the be useful adjuncts to radiotherapy. However, it must be established that they have no adverse effects and that normal tissue radiosensitivity is not enhanced

    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 micromol/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 micromol/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 micromol/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. PMID:12515305

    The growth of abnormally large grains in textured Ni-5at.%W substrates for high-temperature superconductors deteriorates the sharp texture of these materials and thus has to be avoided. Therefore the growth of abnormal grains is investigated and how it is influenced by the grain orientation and the annealing atmosphere. Texture measurements and grain growth simulations show that the grain orientation only matters so far that a high-angle grain boundary exists between an abnormally growing grain and the Cube-orientated matrix grains. The annealing atmosphere has a large influence on abnormal grain growth which is attributed to the differences in oxygen partial pressure.

    Lesions involving the splenium of the corpus callosum (SCC) have been rarely reported in cases of hypoglycemic brain injury. We identified signal abnormalities in the SCC in three adult patients with hypoglycemic encephalopathy by using diffusion-weighted imaging (DWI) on a 1.5-T MR scanner. Repeat DWI was performed in all patients following a marked clinical improvement, and MR angiography and routine MRI were also performed. We examined each patient's detailed medical history and blood laboratory tests in order to exclude other conditions causing similar SCC abnormalities. Initial DWI was performed during which each patient showed altered mental status that was attributed to profound hypoglycemia. We observed an identical pattern of DWI abnormality characterized by high signals in the SCC with apparent diffusion coefficient reductions that were reversed completely within several days following appropriate correction of hypoglycemia. T2-weighted or FLAIR images also showed no residual lesion in the SCC and MR angiography was normal in all patients. These case reports suggest that the SCC should be added to the list of selective vulnerability to hypoglycemia and that hypoglycemia, in turn, be included in the differential diagnosis of reversible SCC abnormalities.

The accuracy of this technique in measuring ineffective erythropoiesis was assessed by comparison with other measurements of the severity of the disease. 6 patients were studied before specific treatment and 2 of these also after treatment. The endogenous production of 14CO was calculated from determinations of the production of CO by a rebreathing technique and of the specific activity of CO washed out from the body CO store by oxygen breathing. The early labelled peak was increased 7-39 times compared to that in healthy control subjects and represented 35-86% of the total production of 14CO as compared to 13% in controls. The early labelled peak was significantly correlated to the Hb concentration, mean red cell volume and endogenous production of CO. 2 patients, twice examined, showed a moderately increased early labelled peak also after specific treatment. This was attributed to persistence of some ineffective erythropoiesis in 1 patient and possibly increased hepatic haem turnover in the other. The magnitude of the early labelled peak and the maximal activity of 14CO found in the samples of CO collected from the body CO store were significantly correlated. In conclusion, with the present method the early peak of 14CO reflected the ineffective erythropoiesis in patients with pernicious anaemia. The early labelled peak could be predicted from the maximal activity of 14CO found in the samples of CO washed out from the body CO store. (author)

    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

    Iron-containing preparations available on the market vary in dosage, salt, and chemical state of iron contained in the preparation, as well as in the iron delivery process (immediate or prolonged-release). The present study aimed at characterizing the serum pharmacokinetics of iron in non pregnant women with iron deficiency anaemia (IDA) following a single oral administration of a prolonged-release ferrous sulphate tablet. This multicenter, single dose, open-label study was conducted in 30 women aged between 18 and 45 years with IDA. A single 160 mg oral dose of ferrous sulphate was given as 2 tablets of 80 mg of Tardyferon(®) under fasting conditions. Blood samples were collected before dosing and until 24 h post-dosing. Serum iron concentrations were determined using a routine colorimetric analytical method. Pharmacokinetic parameters were determined from the serum concentration profiles using a non compartmental approach. Serum profiles showed elevated levels of iron up to 12 h after drug intake. The median time to maximum serum concentrations (Tmax) occurred 4 h post-dosing. Between 2 and 8 h post-dosing, mean serum iron concentrations fluctuated by only 20%. Additionally, C8h and C12h represented on average 78.6% and 47.5% of the Cmax, respectively. This study demonstrates that a single oral dose of 160 mg Tardyferon(®) administered under fasting condition to 30 women with IDA leads to an optimal long-lasting release of iron in the gastrointestinal tract in the targeted population. This allows the attainment and maintenance of elevated serum iron levels for up to 12 h after administration. PMID:25989284

    In this study, we dealt with 11 species of nonhuman primates across 10 zoos in India. We recorded behavior as instantaneous scans between 9 a.m. and 5 p.m. In the study, we segregated behaviors for analyses into abnormal, undesirable, active, and resting. The 4 types of abnormal behavior exhibited included floating limb, self-biting, self-clasping, and stereotypic pacing. In the study, we recorded 2 types of undesirable behavior: autoerotic stimulation and begging. Langurs and group-housed macaques did not exhibit undesirable behaviors. A male lion-tailed macaque and a male gibbon exhibited begging behavior. autoerotic stimulation and self-biting occurred rarely. Males exhibited higher levels of undesirable behavior than did females. Animals confiscated from touring zoos, circuses, and animal traders exhibited higher levels of abnormal behaviors than did animals reared in larger, recognized zoos. The stump-tailed macaque was the only species to exhibit floating limb, autoerotic stimulation, self-biting, and self-clasping. Our results show that rearing experience and group composition influence the proportions of abnormal behavior exhibited by nonhuman primates in captivity. The history of early social and environmental deprivation in these species of captive nonhuman primates probably is critical in the development of behavioral pathologies. Establishing this will require further research. PMID:14965782

    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.

    Vitamin B(12) stores at birth are adequate for infants until the end of the first year of life even if it 's concentration in maternal breast milk is low. However, there are some situations in which infants have depleted vitamin B(12) stores and in addition have a low dietary intake of cobalamin. Vitamin B(12) depletion occurs in infants who are exclusively breastfed by mothers who have unrecognized pernicious anemia or are strict vegetarians for many years. In those infants symptoms of bone marrow disfunction and impaired development of the central nervous system appear already in the first months of life. Unrecognized cobalamin deficiency may lead to serious neurologic consequences, and even to the death of the child. The authors present a case of a 7.5 month old girl admitted to the Department of Paediatrics, Haematology, Oncology and Endocrinology. Gdańsk Medical University suspected of acute leukaemia. Based on a detailed diagnostic procedure a final diagnosis of vitamin B(12) deficiency anaemia was established. The child was exclusively breast-fed. Results of investigations into the reason for cobalamin deficiency in the patient s organism. Led to the diagnosis of pernicious anaemia in the mother. Such a suspicion had been made during pregnancy, but no continuation of investigations nor appropriate treatment were implemented. After treatment with vitamin B(12) supplements and modification of the diet the patient improved quickly and remarkably. A few months follow-up was enough to observe remarkable improvement of psychomotor development of this child. PMID:15738604

    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.

    Full Text Available Background: Sickle cell anaemia (SCA remains associated with high risks of morbidity and early death. Children with SCA are at high risk for ischaemic stroke and transient ischaemic attacks, secondary to intracranial arteriopathy involving carotid and cerebral arteries. Allogeneic haematopoietic stem cell transplantation (HSCT is the only curative treatment for SCA. We report our experience with transplantation in a group of patients with the Black African variant of SCA. Patients and Methods: This study included 31 consecutive SCA patients who underwent bone marrow transplantation from human leukocyte antigen (HLA-identical sibling donors between 2010 and 2014 following a myeloablative-conditioning regimen. Results: The median patient age was 10 years (range 2-17 years. Before transplantation, 14 patients had recurrent, painful, vaso-occlusive crisis; ten patients had recurrent painful crisis in association with acute chest syndrome; three patients experienced ischaemic stroke and recurrent vaso-occlusive crisis; two patients experienced ischaemic stroke; one patient exhibited leukocytosis; and one patient exhibited priapism. Of the 31 patients, 28 survived without sickle cell disease, with Lansky/Karnofsky scores of 100. All surviving patients remained free of any SCA-related events after transplantation. Conclusion: The protocols used for the preparation to the transplant in thalassaemia are very effective also in the other severe haemoglobinopathy as in the sickle cell anaemia with 90% disease free survival. Today, if a SCA patient has a HLA identical family member, the cellular gene therapy through the transplantation of the allogeneic haemopoietic cell should be performed. Tomorrow, hopefully, the autologous genetically corrected stem cell will break down the wall of the immunological incompatibility.

    Full Text Available Allogeneic blood transfusion (ABT is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD, especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient, febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion-related immuno-modulation, and transmission of almost all infectious diseases (bacteria, virus, protozoa and prion, which might result in increased risk of morbidity and mortality. Unfortunately, the main physiological goal of ABT, i.e. to increase oxygen consumption by the hypoxic tissues, has not been well documented. In contrast, the ABT is usually misused only to increase the haemoglobin level within a fixed protocol [mostly two by two packed red blood cell (PRC units] independently of the patient’s tolerance to normovolemic anaemia or his clinical response to the transfusion of PRC units according to a “one-by-one” administration schedule. Evidence-based clinical guidelines may promote best transfusion practices by implementing restrictive transfusion protocols, thus reducing variability and minimizing the avoidable risks of transfusion, and the use of autologous blood and pharmacologic alternatives. In this regard, preoperative autologous blood donation (PABD consistently diminished the frequency of ABT, although its contribution to ABT avoidance is reduced when performed under a transfusion protocol. In addition, interpretation of utility of PABD in surgical IBD patients is hampered by scarcity of published data. However, the role of autologous red blood cells as drug carriers is promising. Finally, it must be stressed that a combination of methods used within well-constructed protocols

  14. Parenteral iron sucrose in iron deficiency anaemia of paediatric chronic kidney disease

    International Nuclear Information System (INIS)

    Background: Erythropoietin (Epo) and iron therapy plays a major role in the management of renal anaemia. Iron sucrose (IS) has been used to treat iron deficiency anaemia (IDA) and to maintain adequate iron store in chronic kidney disease (CKD). The objective of the study was to determine the response and safety of IS in the treatment of IDA. Methods: This retrospective study was carried out in the Department of Nephrology, National Institute of Child Health, Karachi from Dec 2008 to Dec 2010. Children aged 6 months to 14 years, CKD-stage 2-5, and IDA were included. Pertinent data including age, gender, serum creatinine (SCr), CKD-stage, aetiology, treatment mode, IS dose, pre- and post-treatment parameters and side effects were collected and analysed. Results: Among 35, majority (66%) were boys. Mean age was 6.97+-4.13 years and mean SCr was 3.78+-3.1 mg/dl. Majority were in CKD-stage 4-5 and treated conservatively. Major aetiologies were hypoplasia-dysplasia (40%), juvenile nephronophthiasis (17.14%), posterior urethral valves, and stones. Baseline mean Hb and Transferrin Saturation (TS) was 7.38+-1.38 g/dl and 11.19+-5.28% respectively. Mean Hb increased to 9.22+-16.32 g/dl with correction of iron deficit (p<0.001) and a sustained rise in Hb was observed after Epo and maintenance iron sucrose. Mean TS% increased to 49.13+-18% (p<0.001). No major side effects were observed except iron overload. Conclusion: Iron sucrose was effective in improving IDA in CKD without significant side effects. Iron sucrose may be used to treat IDA with monitoring for iron overload. (author)

    Objective To investigate which structural MR abnormalities discriminate symptomatic knee osteoarthritis (OA), taking co-occurrence of abnormalities in all compartments into account. Methods The Netherlands Epidemiology of Obesity (NEO) study is a population-based cohort aged 45–65 years. In 1285 participants (median age 56 years, 55% women, median body mass index (BMI) 30 kg/m2), MRI of the right knee were obtained. Structural abnormalities (osteophytes, cartilage loss, bone marrow lesions (BMLs), subchondral cysts, meniscal abnormalities, effusion, Baker's cyst) at 9 patellofemoral and tibiofemoral locations were scored following the knee OA scoring system. Symptomatic OA in the imaged knee was defined following the American College of Rheumatology criteria. Logistic ridge regression analyses were used to investigate which structural abnormalities discriminate best between individuals with and without symptomatic OA, crude and adjusted for age, sex and BMI. Results Symptomatic knee OA was present in 177 individuals. Structural MR abnormalities were highly frequent both in individuals with OA and in those without. Baker's cysts showed the highest adjusted regression coefficient (0.293) for presence of symptomatic OA, followed by osteophytes and BMLs in the medial tibiofemoral compartment (0.185–0.279), osteophytes in the medial trochlear facet (0.262) and effusion (0.197). Conclusions Baker's cysts discriminate best between individuals with and without symptomatic knee OA. Structural MR abnormalities, especially in the medial side of the tibiofemoral joint and effusion, add further in discriminating symptomatic OA. Baker's cysts may present as a target for treatment.

    2007-01-01

    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

    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

  3. [Walking abnormalities in children].

    Segawa, Masaya

    2010-11-01

    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

    Full Text Available This research work presents a method for automatic classification of medical images in two classes Normal and Abnormal based on image features and automatic abnormality detection. Our proposed system consists of four phases Preprocessing, Feature extraction, Classification, and Post processing. Statistical texture feature set is derived from normal and abnormal images. We used the KNN classifier for classifying image. The KNN classifier performance compared with kernel based SVM classifier (Linear and RBF. The confusion matrix computed and result shows that KNN obtain 80% classification rate which is more than SVM classification rate. So we choose KNN algorithm for classification of images. If image classified as abnormal then post processing step applied on the image and abnormal region is highlighted on the image. The system has been tested on the number of real CT scan brain images.

    The purpose of the study was to develop a mathematical model for determining knee loads for abnormal gait. Abnormal gait was defined as a person with varus, i.e. “bowleggedness”, or a person who had an external rotation of the femur (or the inability to internally rotate the femur) which caused an indirect varus in the forward positions of gait. Conditions such as these have been observed clinically to result in increased wear on the medial condyle of total knee replacements. This problem was...

    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.

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 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.

    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.

    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.

    Feline immunodeficiency virus (FIV) grown in cat lymphocyte and thymocyte cultures was labelled with L-[35S]methionine or [3H]glucosamine and virus-coded proteins were identified using immunoprecipitation. Polypeptides with apparent Mr values of 15K, 24K, 43K, 50K, 120K and 160K were detected. An additional polypeptide of 10K was detected by Western blot analysis. The two highest Mr species sometimes appeared as one band, of which only the 120K polypeptide was glycosylated. In the presence of tunicamycin gp120 was no longer detectable and a non-glycosylated precursor of 75K was found instead. Pulse-chase experiments suggested that the smaller polypeptides p24 and p15 are cleavage products of both p160 and p50. Western blot analysis using a rabbit serum directed against p26 of equine infectious anaemia virus (EIAV) and an anti-EIAV horse serum from a field case of infection revealed a cross-reactivity with p24 of FIV. Cat sera collected late after experimental FIV infection recognized p26 of EIAV, indicating a reciprocal cross-reactivity. PMID:1690264

    Full Text Available Nigeria has the fourth highest prevalence of TB and the highest prevalence of Sickle cell anaemia (SCA in the world. SCA patients have impaired immunity and are vulnerable to TB. Hence, we studied the haematological indices of SCA patients with TB in Nigeria. A total of 23 SCA patients with TB were studied in parallel with equal number of age and sex matched SCA patients without TB. SCA patients with TB had significantly lower haematocrit, higher level of circulating sickle cells (CSCs and similar level of reticulocyte count in comparison to patients without TB. SCA patients with TB had significantly higher mean WBC count associated with higher frequency of neutrophilia in comparison to those without TB. Monocytosis and eosinopenia were exclusively found in SCA patients with TB at frequencies of 52% and 65% respectively. Lymphocyte and basophil counts were normal in all patients with and without TB. Mean platelet counts were high in both patient groups but the frequency of thrombocytosis was significantly higher in patients with TB. SCA patients with TB had significantly higher mean ESR than their counterparts without the infection. The findings of this study  revealed that TB in SCA patients was associated with rising level of CSCs, falling level of haematocrit, sub-optimal reticulocytosis, neutrophilia, monocytosis, thrombocytosis, eosinopenia and rising level of ESR. Hence, SCA patients presenting with these haematological indices should be investigated for TB.

  2. Observations on the pathogenesis of anaemia in fascioliasis and on immunoglobulin metabolism

    International Nuclear Information System (INIS)

    Proline, an excretory/secretory product of liver flukes, was investigated as a possible mediator of anaemia through haemolysis or dyshaemopoiesis in fluke infected animals. Infusion of 700 μmol proline per rabbit per day for 14 days did not significantly alter the halflife (t1/2) of 51Cr labelled erythrocytes nor did it interfere with plasma clearance and utilization of 59Fe in rabbits. Consequently, it was concluded that proline did not interfere with haemoglobin synthesis or induced haemolysis in rabbits at test dose level. The metabolism of radiolabelled IgG was also investigated in calves infected with Fasciola gigantica. In two calves given 1,000 metacercariae of F. gigantica ten weeks earlier, the mean t1/2 of 125I labelled IgG was 74 h, compared with 100 h in uninfected controls. The faecal clearance of 125I labelled IgG was correspondingly higher among infected calves, indicating that serum IgG was being lost into the gut in excessive quantities, probably via the bile.

  3. Evolutionary mechanisms involved in the virulence of infectious salmon anaemia virus (ISAV), a piscine orthomyxovirus

    International Nuclear Information System (INIS)

    Infectious salmon anaemia virus (ISAV) is an orthomyxovirus causing a multisystemic, emerging disease in Atlantic salmon. Here we present, for the first time, detailed sequence analyses of the full-genome sequence of a presumed avirulent isolate displaying a full-length hemagglutinin-esterase (HE) gene (HPR0), and compare this with full-genome sequences of 11 Norwegian ISAV isolates from clinically diseased fish. These analyses revealed the presence of a virulence marker right upstream of the putative cleavage site R267 in the fusion (F) protein, suggesting a Q266 → L266 substitution to be a prerequisite for virulence. To gain virulence in isolates lacking this substitution, a sequence insertion near the cleavage site seems to be required. This strongly suggests the involvement of a protease recognition pattern at the cleavage site of the fusion protein as a determinant of virulence, as seen in highly pathogenic influenza A virus H5 or H7 and the paramyxovirus Newcastle disease virus

    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

    2009-01-01

    Full Text Available Background: Traditional wisdom is that wound healing is directly related to haemoglobin level in the blood; therefore blood transfusion is given in anaemic patients to raise the haemoglobin level for better wound healing. Methods: Evaluation of wound healing in the form of split thickness skin graft take was done in 35 normovolaemic anaemic patients (haemoglobin level of < 10 gm/ dl and compared with control group (patients with haemoglobin level of 10 or > 10 gm/ dl. Results: There was no statistically significant difference in mean graft take between the two groups. Conclusion: It is not mandatory to keep haemoglobin level at or> 10 g/dL or PCV value at or> 30% for skin graft take, as mild to moderate anaemia per se does not cause any deleterious effect on wound healing; provided perfusion is maintained by adequate circulatory volume. Prophylactic transfusion to increase the oxygen carrying capacity of the blood for the purpose of wound healing is not indicated in asymptomatic normovolemic anaemic patients (with haemoglobin levels greater than 6g/dL without significant cardiovascular or pulmonary disease.

  6. 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.

  7. I-131 therapy for hyperthyroidism in carbimazole induced acute aplastic anaemia

    International Nuclear Information System (INIS)

    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

    Sickle cell anaemia (SCA) is the most frequent genetic haemoglobinopathy, which exhibits a highly variable clinical course characterized by hyper-coagulable and pro-inflammatory states, as well as endothelial dysfunction. Extracellular microvesicles are released into biological fluids and play a role in modifying the functional phenotype of target cells. We hypothesized that potential differences in plasma-derived extracellular microvesicles (EV) function and cargo from SCA patients may underlie divergent clinical trajectories. Plasma EV from SCA patients with mild, intermediate and severe clinical disease course were isolated, and primary endothelial cell cultures were exposed. Endothelial cell activation, monocyte adhesion, barrier disruption and exosome cargo (microRNA microarrays) were assessed. EV disrupted the endothelial barrier and induced expression of adhesion molecules and monocyte adhesion in a SCA severity-dependent manner compared to healthy children. Microarray approaches identified a restricted signature of exosomal microRNAs that readily distinguished severe from mild SCA, as well as from healthy children. The microRNA candidates were further validated using quantitative real time polymerase chain reaction assays, and revealed putative gene targets. Circulating exosomal microRNAs may play important roles in predicting the clinical course of SCA, and in delineation of individually tailored, mechanistically-based clinical treatment approaches of SCA patients in the near future.

    The medical records of 21 dogs with concurrent immune-mediated haemolytic anaemia (imha) and severe thrombocytopenia (defined as an automated platelet count of less than 50x10(9)/l, confirmed by the examination of a blood smear) were reviewed. Their mean (sd) age was 5.8 (2.5) years. When compared with the 24,759 dogs in the hospital population for the same period Airedale terriers and dobermanns appeared to be over-represented with odds ratios of 22.5 (95 per cent confidence interval [ci] 5.2 to 97.9) and 7.6 (95 per cent ci 1.8 to 32.7) respectively. The median duration of the dogs' clinical signs was seven days, with a range from one to 17 days. Eleven of the dogs had a history of a tendency to bleed, and 15 had evidence of bleeding when examined. Twenty of the 21 dogs had been treated with glucocorticoids, nine with vincristine, and seven with azathioprine. Their median stay in hospital was four days, with a range from one to 17 days. The median period for which they survived after admission to hospital was five days, with a range from one to 558 days, and 16 of the 21 dogs had died or been euthanased within 30 days of their admission.

    Lentiviral vectors are being developed to satisfy a wide range of currently unmet medical needs. Vectors destined for clinical evaluation have been rendered multiply defective by deletion of all viral coding sequences and nonessential cis-acting sequences from the transfer genome. The viral envelope and accessory proteins are excluded from the production system. The vectors are produced from separate expression plasmids that are designed to minimize the potential for homologous recombination. These features ensure that the regeneration of the starting virus is impossible. It is a regulatory requirement to confirm the absence of any replication competent virus, so we describe here the development and validation of a replication competent lentivirus (RCL) assay for equine infectious anaemia virus (EIAV)-based vectors. The assay is based on the guidelines developed for testing retroviral vectors, and uses the F-PERT (fluorescent-product enhanced reverse transcriptase) assay to test for the presence of a transmissible reverse transcriptase. We have empirically modelled the replication kinetics of an EIAV-like entity in human cells and devised an amplification protocol by comparison with a replication competent MLV. The RCL assay has been validated at the 20 litre manufacturing scale, during which no RCL was detected. The assay is theoretically applicable to any lentiviral vector and pseudotype combination.

METHODS: the case of a zoung male patient with a severe acute posthaemorrhagic anaemia caused by an serious episode of bleeding from the lower gastrointestinal tract is disscussed. We comment upon the efficiency of our diagnostic procedures and therapeutic strategy in this case, with a final review of the literature. RESULTS: gastro-duodenal endoscopy and colonoscopy couldn't establish the source of bleeding but gave a valuable guide for our suspicions. Not even the scintigraphic study with Tc –99m per technectate was able to give us more information. Laparotomy revealed a Meckel's diverticulum with a bleeding ulcer; segmentary enterectomy was performed. CONCLUSIONS: obviously neither upper nor lower endoscopy could establish the source of bleeding in our case; still they guiding our suspicions toward this kind of lesion. Laparoscopy if available could have established the diagnosis and give the terapeutic solution at the time. Considering the severity of bleeding episods, laparotomy was, at that time, the single valid option; we think it should have been performed much earlier, after the first bleeding episodes.

    We present a new interpretation of dark energy in terms of an \\textit{Abnormally Weighting Energy} (AWE). This means that dark energy does not couple to gravitation in the same way as ordinary matter, yielding a violation of the weak and strong equivalence principles on cosmological scales. The resulting cosmological mechanism accounts for the Hubble diagram of type Ia supernovae in terms of both cosmic acceleration and variation of the gravitational constant while still accounting for the pr...

  20. Study of the effects of the nutritional and socio-economic factors on the prevalance of iron deficiency anaemia among pregnant women

    International Nuclear Information System (INIS)

    This Study was conducted with the following objectives: 1.determine the prevalance of iron deficiency anaemia among pregnant women. 2. Determine the factors that affect the iron status of pregnant women (nutritional, social etc...). For the assessment of iron status during pregnancy, 30 healthy pregnant women were included in a longitudinal study from the first to the third trimester. One blood sample was taken in the first trimester and a second blood sample was taken in the third trimester. All subjects were given ten iron supplement tablets at the beginning of the study by the researcher. However, they did not receive any other iron supplements throughout their pregnancy. Ten healthy non-pregnant women were included in the study to serve as controls. The iron status was assessed using the following parameters: haemoglobin and serum ferritin levels which was measured using ImmunoRadiometric Assay (IRMA). The nutritional status was assessed from a nutritional/socio-economic questionnaire that was answered by the study and control groups. Both the study and the control groups had haemoglobin level below the WHO cut-off points (0.05) between the level of haemoglobin of control and the study groups in the first and third trimester. There was significant difference (p<0.01) in the level of serum ferritin between the study and control group. The study group had a higher level of serum ferritin than the control. there was also high significant difference (p<0.01) in the level of serum ferritin between the first and third trimester in which a large decrease in the level of serum ferritin was apparent. The results of this study also showed that 16.5% had IDA (Iron Defeciency Anaemia) in the first trimester whereas 27.6% had depleted iron stores without frank defeciency. The prevalance of IDA increased to 26.4% in the third trimester while those who had depleted iron stores increased to 46.6%. Almost 50% of pregnant women started their pregnancy with adequate iron stores

    Full Text Available The purpose of this study was to establish a correlation between the presence of chromosomal abnormalities in one of the partners and infertility. This retrospective study was performed at the Department of Reproductive Medicine, Life Memorial Hospital, Bucharest, Romania, between August 2007 to December 2011. Two thousand, one hundred and ninety-five patients with reproductive problems were investigated, and the frequency of chromosomal abnormalities was calculated. The control group consisting of 87 fertile persons who had two or more children, was investigated in this retrospective study. All the patients of this study were investigated by cytogenetic techniques and the results of the two groups were compared by a two-tailed Fisher’s exact test. In this study, 94.99% patients had a normal karyotype and 5.01% had chromosomal abnormalities (numerical and structural chromosomal abnormalities. In the study group, numerical chromosomal abnormalities were detected in 1.14% of infertile men and 0.62% of infertile women, and structural chromosomal abnormalities were detected in 1.38% of infertile men and 1.87% of infertile women, respectively. The correlation between the incidence of chromosomal anomalies in the two sexes in couple with reproductive problems was not statistically significant. Recently, a possible association between infertility and chromosomal abnormalities with a significant statistical association has been reported. Our study shows that there is no association between chromosomal abnormalities and infertility, but this study needs to be confirmed with further investigations and a larger control group to establish the role of chromosomal abnormalities in the etiology of infertility.

  8. MRI study on urinary abnormalities of fetus

    International Nuclear Information System (INIS)

    Objective: To illustrate the important complemental function of MRI in dignosing the urinary abnormalities of the fetus by analyzing MR features. Methods: MRI findings in 34 fetal urinary abnormalities were retrospectively analyzed. Results: Upper urinary tract dilatation was found in 12 cases: one case presented obstructed right renal dysplasia and was on the follow-up, postnatal MR imaging proved the duplex anomaly in one case, one case showed left PUJO on postnatal US imaging and prepared to surgery, 7 cases were normal on postnatal US imaging, 2 cases were lost to follow up. Bilateral urinary anomalies were found in 7 cases: Muhicystic renal dysplasia (n=3), Combined horseshoe kidney in 2 fetuses and bilateral renal aplasia in one case. Bilateral renal dysplasia was diagnosed in 2 cases, one was still bom and proved by autopsy and the other was lost to follow up. The case of bilateral renal agenesis displayed the appearance of sirenomelia on general specimen. The case of right renal agenesis associated contralateral kidney dyspalsia (n=1) was lost to follow up. MR imaging showed low signal intensity of lung and oligohydramnios in the bilateral anomalies. Unilateral urinary anomalies was found in 15 cases, including 9 cases of unilateral renal dysplasia. Two fetuses were aborted and 3 fetuses were proved with postnatal US or MR. One was lost to follow up; 3 cases were on the follow-up. There were 4 cases of unilateral renal agenesis, two fetuses were aborted and 2 fetuses were proved with postnatal US or MR imaging. The case of ectopic kidney was proved with postnatal US imaging. One case of urachal cyst was aborted without autopsy. In the unilateral anomalies, the volume of amniotic fluid was normal, and the fetal lung presented homogenious high signal intensity. Conclusion: As a complemental method, MRI is of great value in displaying and dignosing the urinary abnormalities of fetus. (authors)

  9. Obesity in show dogs.

    2012-08-11

    Obesity is an important disease with a growing incidence. Because obesity is related to several other diseases, and decreases life span, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain breeds is often suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, we investigated 1379 dogs of 128 different breeds by determining their body condition score (BCS). Overall, 18.6% of the show dogs had a BCS >5, and 1.1% of the show dogs had a BCS>7. There were significant differences between breeds, which could be correlated to the breed standards. It warrants firm discussions with breeders and judges in order to come to different interpretations of the standards to prevent overweight conditions from being the standard of beauty. PMID:22882163

    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. PMID:23631336

    Hydroxycarbamide (hydroxyurea) provides laboratory and clinical benefits for adults and children with sickle cell anaemia (SCA). Given its mechanism of action and prior reports of genotoxicity, concern exists regarding long-term toxicities and possible carcinogenicity. We performed cross-sectional analyses of chromosome stability using peripheral blood mononuclear cells (PBMC) from 51 children with SCA and 3-12 years of hydroxycarbamide exposure (mean age 13·2 ± 4·1 years), compared to 28 children before treatment (9·4 ± 4·7 years). Chromosome damage was less for children receiving hydroxycarbamide than untreated patients (0·8 ± 1·2 vs. 1·9 ± 1·5 breaks per 100 cells, P = 0·004). There were no differences in repairing chromosome breaks after in vitro radiation; PBMC from children taking hydroxycarbamide had equivalent 2 Gy-induced chromosome breaks compared to untreated patients (30·8 ± 16·1 vs. 31·7 ± 8·9 per 100 cells, P = not significant). Radiation plus hydroxycarbamide resulted in similar numbers of unrepaired breaks in cells from children on hydroxycarbamide compared to untreated patients (95·8 ± 44·2 vs. 76·1 ± 23·1 per 100 cells, P = 0·08), but no differences were noted with longer exposure (97·9 ± 42·8 breaks per 100 cells for 3-6 years of hydroxycarbamide exposure vs. 91·2 ± 48·4 for 9-12 years of exposure). These observations provide important safety data regarding long-term risks of hydroxycarbamide exposure for children with SCA, and suggest low in vivo mutagenicity and carcinogenicity. PMID:21542824

    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.

  13. Integrity of the iron transport process in mice with X-linked anaemia

    International Nuclear Information System (INIS)

    The defect in iron (Fe) absorption in X-linked anaemia (sla) remains an enigma; absorption of a tracer dose of Fe is impaired in mice raised on an iron-containing cube diet but not in those raised on an iron-deficient diet. Because cobalt (Co) shares a similar intestinal transport pathway with Fe, a study was made of the effect of iron deficient diet on Co absorption. The duodenum of sla and genetically normal mice was perfused for 30 min with labelled solutions containing Co or Fe. Co uptake and transfer were similar in sla and normals fed cubes whereas Fe uptake and transfer were less in sla than in normals. The iron deficient diet caused an increase in the uptake and transfer of Co and Fe in sla and normals. When Co and Fe were perfused together in sla fed deficient diet, the uptake and transfer of each metal was less than when perfused alone. The distribution of Fe and Co in subcellular mucosal fractions was determined by a differential centrifugation technique. Deficient diet resulted in a directionally similar change in the subcellular distribution of Co and Fe in sla and normals. The increase in Co as well as Fe absorption in the sla on an iron deficient diet to the same high level found in genetically normal animals, and the inhibitory effect of each metal on the absorption of the other suggests that the absorption defect in sla is unlikely to be due to a primary defect in the function of the transport carrier.

    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

  18. Beyond anaemia management: evolving role of erythropoietin therapy in neurological disorders, multiple myeloma and tumour hypoxia models.

    2005-01-01

    Recombinant human erythropoietin (epoetin) has become the standard of care in the treatment of anaemia resulting from cancer and its treatment, and chronic kidney disease. The discovery that erythropoietin and its receptor are located in regions outside the erythropoietic system has led to interest in the potential role of epoetin in other tissues, such as the central nervous system. Animal studies have shown that systemically applied epoetin can cross the blood-brain barrier, where it reduces tissue injury associated with stroke, blunt trauma and experimental autoimmune encephalomyelitis. Pilot studies in humans have shown that epoetin treatment given within 8 h of stroke reduces infarct size and results in a significantly better outcome when compared with placebo treatment. Studies also suggest that epoetin has the potential to improve cognitive impairment associated with adjuvant chemotherapy in patients with cancer. Anaemia is a major factor causing tumour hypoxia, a condition that can promote changes within neoplastic cells that further tumour survival and malignant progression and also reduces the effectiveness of several anticancer therapies including radiotherapy and oxygen-dependent cytotoxic agents. Use of epoetin to prevent or correct anaemia has the potential to reduce tumour hypoxia and improve treatment outcome. Several therapeutic studies in anaemic animals with experimental tumours have shown a beneficial effect of epoetin on delaying tumour growth. Furthermore, clinical observations in patients with multiple myeloma and animal studies have suggested that epoetin has an antimyeloma effect, mediated via the immune system through activation of CD8+ T cells. Therefore, the role of epoetin may go well beyond that of increasing haemoglobin levels in anaemic patients, although additional studies are required to confirm these promising results.

    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

  4. Ventilation abnormalities in pulmonary embolus

    International Nuclear Information System (INIS)

    The ventilation scans of 11 patients with angiographically-proven PE were reviewed. All patients had one or more lung perfusion defects. The chest roentgenograph was abnormal in 11 of the patients. The ventilation studies were performed in the posterior positron prior to the perfusion lung scan using Xe-133. The ventilation study consists of washin, equilibrium, and washout images. In four patients with normal washin there was retention of the Xe-133 (delayed washout) at the site of the perfusion defect. All had roentgenographic abnormalities. Another pattern was observed at the sites of some perfusion defects in six patients. In these, there was decreased washin at the perfusion defect location. Two patients had both decreased washin and delayed washout. In only one case was the typical ventilation pattern of normal washin and normal washout. The method of retention is unclear, but may be due to decreased clearance of Xe-133 secondary to decreased blood flow in the area or deposition of some fat soluble component left at the site of embolization. The etiology of the reduced washin is unclear, but may be due to reduced surfactant production. This study suggests that more attention must be paid to the ventilation study, where there may be additional clues to the diagnosis of pulmonary embolus

    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.

  6. Cognition and brain abnormalities on MRI in pituitary patients

    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

    We propose to detect abnormal events via a sparse subspace clustering algorithm. Unlike most existing approaches, which search for optimized normal bases and detect abnormality based on least square error or reconstruction error from the learned normal patterns, we propose an abnormality...... measurement based on the difference between the normal space and local space. Specifically, we provide a reasonable normal bases through repeated K spectral clustering. Then for each testing feature we first use temporal neighbors to form a local space. An abnormal event is found if any abnormal feature is...

    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

    Full Text Available Chromosomal abnormalities are involved in the etiology of recurrent spontaneous pregnancy loss and sub-fertility. The purpose of this study was to determine the frequency and contribution of chromosomal abnormalities in recurrent miscarriages. The results obtained and literature review are helpful in understanding the importance of cytogenetics analysis of female infertility. To investigate the distribution of chromosomal abnormalities in the Romanian population with recurrent miscarriage, karyotype analysis by G-banding was performed from peripheral blood in 967 women infertility. Results: Chromosomal abnormalities were found to 79 women (8,17%. The percentage of chromosomal abnormalities in the studied population correlates with the data in the literature. Chromosomal abnormalities could play the important role in etiology of infertility and are more frequently detected in this group of patients compared to general population. In the infertile couples balanced chromosomal abnormalities are the main cause of spontaneous abortions.

  15. Functional neuroimaging abnormalities in idiopathic generalized epilepsy

    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. .

  17. MR evaluation of visceroatrial situs abnormality

    International Nuclear Information System (INIS)

    Thirteen patients with visceroatrial situs abnormalities were evaluated by magnetic resonance (MR) imaging. Eleven patients were confirmed surgically. Two patients were diagnosed by MRI and cardiac catheterization. Right isomerism was found in seven patients, left isomerism in two, and situs in versus in four. For the determination of situs, we evaluated the morphology of atrial appendages and main bronchi, the relationship between abdominal aorta and inferior vena cava (lVC), and the status of upper abdominal viscera. The bilateral atrial morphology was differentiated in 8 of 12 patients. The bronchial situs was determined in 11 of 12 patients. Juxtaposition of abdominal aorta and IVC was found in 6 of 7 with right isomerism. lVC interruption with azygos continuation was found in all two with left isomerism. Incidentally three cases of short pancreas were found. MR imaging showed all structures relevant for the assessment of situs, thus obvrating the need for performing additional diagnostic procedures. MR imaging, therefore, is a valuable tool in the clinical management of patients who are suspected of having a situs abnormality

    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. PMID:19002453

    The identification of an underlying chromosome abnormality frequently marks the endpoint of a diagnostic odyssey. However, families are frequently left with more questions than answers as they consider their child's future. In the case of rare chromosome conditions, a lack of longitudinal data often makes it difficult to provide anticipatory guidance to these families. The objective of this study is to describe the lifespan, educational attainment, living situation, and behavioral phenotype of adults with chromosome 18 abnormalities. The Chromosome 18 Clinical Research Center has enrolled 483 individuals with one of the following conditions: 18q-, 18p-, Tetrasomy 18p, and Ring 18. As a part of the ongoing longitudinal study, we collect data on living arrangements, educational level attained, and employment status as well as data on executive functioning and behavioral skills on an annual basis. Within our cohort, 28 of the 483 participants have died, the majority of whom have deletions encompassing the TCF4 gene or who have unbalanced rearrangement involving other chromosomes. Data regarding the cause of and age at death are presented. We also report on the living situation, educational attainment, and behavioral phenotype of the 151 participants over the age of 18. In general, educational level is higher for people with all these conditions than implied by the early literature, including some that received post-high school education. In addition, some individuals are able to live independently, though at this point they represent a minority of patients. Data on executive function and behavioral phenotype are also presented. Taken together, these data provide insight into the long-term outcome for individuals with a chromosome 18 condition. This information is critical in counseling families on the range of potential outcomes for their child. PMID:25403900

  6. Intravenous iron supplementation in the anaemia of renal and cardiac failure--a double-edged sword?

    Science.gov (United States)

    Slotki, Itzchak

    2005-07-01

    The anaemia of chronic kidney disease (CKD) is efficiently corrected with a combination of recombinant erythropoietin (rhEPO) and intravenous iron supplementation. Recently, patients with severe cardiac failure and anaemia have also been shown to benefit from this treatment. However, iron excess may lead to the production of free radicals and has been incriminated in the pathogenesis of atherosclerosis and increased risk of infection, the two major causes of death in end-stage renal disease. The exact risk of excess iron supplementation has not been defined and, in the absence of sensitive and specific indicators of iron overload, the risk remains difficult to quantify. There is increasing epidemiological evidence incriminating iron overload as a risk factor in CKD, but direct evidence is still hard to obtain. The precise role of iron is complicated further by the complex inter-relationships between iron metabolism and the inflammatory process characteristic of CKD. The recent discovery of the antimicrobial peptide, hepcidin, may shed light on these inter-relationships. New methods for quantifying non-transferrin-bound (or labile plasma) iron may help in the future to identify patients at risk for toxicity from excess iron supplementation. PMID:16024827

    Kehinde Sola Akinlade

    Full Text Available OBJECTIVE: This study assessed the diagnostic performance and prognostic properties of C-reactive protein (CRP, copeptin and cortisol in individuals with sickle cell anaemia (SCA. DESIGN: Prospective case-control study. METHODS: Sixty consecutive SCA subjects (18-40 years comprising 30 subjects in the steady state and 30 subjects in vaso-occlusive crisis (VOC were recruited into this study. Thirty (30 apparently healthy individuals with HbAA genotype served as controls. ELISA was used for the determination of serum levels of copeptin, CRP and cortisol. Data obtained were statistically analyzed using the Student's t-test and Mann Whitney U as appropriate and P<0.05 was considered significant. RESULTS: SCA subjects in VOC had significantly lower copeptin level and significantly higher CRP level compared with controls. However, serum levels of copeptin, cortisol and CRP were significantly higher in SCA subjects in VOC compared with SCA subjects in steady state. Furthermore, CRP had the widest Area under the ROC curve (AUROC than copeptin and cortisol. No significant difference was observed in the levels of copeptin, CRP and cortisol when SCA subjects in VOC who were hospitalized for less ≤ 5 days were compared with subjects who had longer stays. CONCLUSION: It could be concluded that C-reactive protein has a superior diagnostic performance for vaso-occlusive crisis in individuals with sickle cell anaemia and that C-reactive protein, cortisol and copeptin are not good prognostic markers in SCA subjects in vaso-occlusive crisis.

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.

    Material and Methods: A cross sectional study was conducted in urban and rural health training centres of a medical college in Pune. The antenatal women were the study subjects. A total of 180 ANC cases were recruited and studies from both the field practice area attending the outpatient clinics. Sociodemographic profile was recorded and anaemia was assessed using recently done haemoglobin reports in the present pregnancy. The study duration was 6 months. GCP and ethical guidelines were followed as advised for human studies. Results: The prevalence of IDA in the study population was 66%. (rural=81%, urban=51%. IDA prevalence was 54% in primigravida and the prevalence increased as gravid status increased. Iron deficiency anaemia was seen statistically significantly associated with residence, illiteracy, type of diet, and gravida status of the pregnant women. Conclusion: IDA has strong relation with residence (urban/rural, literacy level, social status, monthly income and dietary habits. " [Natl J Community Med 2016; 7(5.000: 351-354

    Full Text Available The risk of diabetes is markedly reduced in men with iron deficiency anaemia (IDA. The nature of this relationship in women is not clear, nor is there information about the influence of ethnicity, given the increased susceptibility of diabetes amongst South Asians and Afro-Caribbeans. We reviewed 3563 patients with a diagnosis of anaemia from 2000 to 2007. The age-adjusted prevalence of vitamin B12 deficiency and IDA was calculated, together with cardiovascular comorbidities amongst Caucasians, South Asians, and Afro-Caribbeans. The prevalence of vitamin B12 deficiency (women only or IDA was markedly higher in South Asians compared to Caucasians and Afro-Caribbeans. Among women with IDA, diabetes was more prevalent among South Asians (45%, 95% CI 39.0–51.0 compared to Caucasians (3.0%, 2.1–4.0; P<0.001. Among South Asian women with vitamin B12 deficiency, the prevalence of diabetes was reduced 8.5% (5.2–12.0. South Asian women with vitamin B12 deficiency had a higher prevalence of myocardial infarction (MI and ischemic heart disease (IHD, but this relationship was reversed in IDA. IDA is associated with a greater prevalence of diabetes in South Asian women, but it is not coordinated by a greater risk of macrovascular complications. Given the cardiovascular impact of diabetes in South Asians, this association merits further study in relation to its pathophysiological implication.

    autoimmunity do not much differ from those observed in the general population; h hyperthyroidism and thyroid cancer are observed rarely during lithium treatment. Recommendations Thyroid function tests (TSH, free thyroid hormones, specific antibodies, and ultrasonic scanning should be performed prior to starting lithium prophylaxis. A similar panel should be repeated at one year. Thereafter, annual measurements of TSH may be sufficient to prevent overt hypothyroidism. In the presence of raised TSH or thyroid autoimmunity, shorter intervals between assessments are advisable (4–6 months. Measurement of antibodies and ultrasonic scanning may be repeated at 2-to-3-year intervals. The patient must be referred to the endocrinologist if TSH concentrations are repeatedly abnormal, and/or goitre or nodules are detected. Thyroid function abnormalities should not constitute an outright contraindication to lithium treatment, and lithium should not be stopped if a patient develops thyroid abnormalities. Decisions should be made taking into account the evidence that lithium treatment is perhaps the only efficient means of reducing the excessive mortality which is otherwise associated with affective disorders.

  12. MRI abnormalities and related risk factors of the brain in patients with neuromyelitis optica

    International Nuclear Information System (INIS)

    Objective: To investigate the MRI features of the brain in patients with neuromyelitis optica (NMO), and to evaluate the correlation between the brain abnormalities and related risk factors. Methods: Fifty-four patients with definite NMO according to 2006 Wingerchuk diagnosis criteria were enrolled in this study. MRI scanning of the brain was performed in these patients. Distribution and signal features of all the lesions were analyzed. A Logistic regression analysis was used to evaluate the risk factors of brain abnormalities. Results: Twenty-four NMO patients (44.4%) showed unremarkable findings and thirty (55.6%) showed abnormalities on brain MRI. Multiple and non-specific small lesions in the subcortical white matter and grey-white matter junction were the most frequent abnormalities on brain MRI (13/30, 43.3%). Typical lesion locations included corpus callosum, subependyma of ventricles, hypothalamus and brain stem. The lesions showed punctate, patchy and linear abnormal signals. Post-contrast MRI showed no abnormal enhancement in 16 cases. Logistic regression analysis showed that coexisting autoimmune disease or infection. history had correlations with abnormalities of the brain on MRI (OR=3.519, P<0.05). Conclusions: There was a high incidence of brain abnormalities in NMO. Subependymal white matter, corpus callosum, hypothalamus and brain stem were often involved in NMO. NMO patients with coexisting autoimmune disease and infection history had higher risk of brain abnormalities. (authors)

    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.

    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 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.

    2011-07-01

    Full Text Available Introduction: Taste and smell abnormalities have proven to be an extremely more complex subject than previously regarded. Wide-ranging nosologic entities arise along with smell and taste alterations, and they can be congenital or acquired. Objective: Analyze the main features of smell and taste dysfunctions. Method: Automated databases were used to collect data, by searching keywords like 'alteration', 'smell', and 'taste'. A non-systematic search was also made in scientific printings and medical books. Literature Review: Smell and taste dysfunctions have a vast etiology, the most significant of which are obstructive nasal and sinusal disease, infections of the upper respiratory tract, cranioencephalic trauma, aging, exposure to toxics and some drugs, nasal or intracranial neoplasias, psychiatric and neurological pathologies, iatrogenic disease, idiopathic and congenital causes. A detailed anamnesis, a careful physical examination and supplementary evaluations are important for the diagnosis of these alterations. Conclusion: As a rule, smell and taste dysfunctions occur in a combined way. The early discovery of such dysfunctions can lead to a more efficient treatment, making the progress of diseases causing them retard and the symptoms less severe. In many cases, treating these alterations is not easy and there needs to be a multidisciplinary cooperation among the otorhinolaryngologist, endocrinologist, neurologist, psychiatrist, among others.

    2010-02-15

    Holoprosencephaly (HPE) is the most common malformation of the human forebrain. When a clinician identifies a patient with HPE, a routine chromosome analysis is often the first genetic test sent for laboratory analysis in order to assess for a structural or numerical chromosome anomaly. An abnormality of chromosome number is overall the most frequently identified etiology in a patient with HPE. These abnormalities include trisomy 13, trisomy 18, and triploidy, though several others have been reported. Such chromosome number abnormalities are almost universally fatal early in gestation or in infancy. Clinical features of specific chromosome number abnormalities may be recognized by phenotypic manifestations in addition to the HPE. PMID:20104610

    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.

  9. Incidence of legal abortions and congenital abnormalities in Hungary

    International Nuclear Information System (INIS)

    The annual and monthly distributions of congenital abnormalities and pregnancy outcomes as confounding factors were evaluated in Hungary in reflection of the accident at the Chernobyl reactor. The different congenital abnormality entities and the components of fetal radiation syndrome did not show a higher rate after the Chernobyl accident in the data-set of the Hungarian Congenital Abnormality Registry. Among confounding factors, the rate of induced abortions did not increase after the Chernobyl accident in Hungary. In the 9th month after the peak of public concern (May and June, 1986) the rate of livebirths decreased. Three indicator conditions: 15 sentinel anomalies as indicators of germinal dominant gene mutations, Down syndrome as an indicator of germinal numerical and structural chromosomal mutations, and unidentified multiple congenital abnormalities as indicators of germinal dominant gene and chromosomal mutations were selected from the material of the Hungarian Congenital Abnormality Registry. Diagnoses were checked, familial and sporadic cases were separated and only the sporadic cases were evaluated. The analysis of indicator conditions did not reveal any measurable germinal mutagenic effect of the Chernobyl accident in Hungary

  10. Report to Congress on abnormal occurrences, October-December 1986

    International Nuclear Information System (INIS)

    Section 208 of the Energy Reorganization Act of 1974 identifies an abnormal occurrence as an unscheduled incident or event which the Nuclear Regulatory Commission determines to be significant from the standpoint of public health or safety and requires a quarterly report of such events to be made to Congress. This report covers the period from October 1 to December 31, 1986. The report states that for this reporting period, there were three abnormal occurrences at the nuclear power plants licensed to operate. The events were (1) loss of low pressure service water systems at Oconee, (2) degraded safety systems due to incorrect torque switch settings on Rotors motor operators at Catawba and McGuire Nuclear Stations, and (3) a secondary system pipe break resulting in the death of four persons at Surry Unit 2. There were six abnormal occurrences at the other NRC licensees. One involved release of americium-241 inside a waste storage building at Wright-Patterson Air Force Base; three involved medical misadministrations, one therapeutic and two diagnostic; one involved a suspension of license for servicing teletherapy and radiography units; and one involved an immediately effective order modifying license and order to show cause issued to an industrial radiography company. There were no abnormal occurrences reported by the Agreement States. The report also contains information updating some previously reported abnormal occurrences

  11. Mechanisms and consequences of paternally transmitted chromosomal abnormalities

    Marchetti, F; Wyrobek, A J

    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.

  12. Studies on anaemia of pregnancy: Therapeutic response to haematinics and on the birth weights of their newborns, and role of malabsorption in anaemic children

    International Nuclear Information System (INIS)

    Anaemia is commonly found in Pakistan especially in pregnant women and children of low socio-economic classes. Malnutrition and anaemia in pregnancy is also associated with impaired foetal and infant health. The pregnant women (n=102) in their third trimester of pregnancy without any obstetrical complications were the subjects for this study and 53.9% of them were anaemic with haemoglobin levels less than 11 g/dl. They were treated with either iron alone (100 mg/day), supplemented with folic acid (10 mg/day) or with folic acid (10 mg/day), vitamin B12 (2μg/day) and vitamin C (140 mg/day) for 4 weeks. The biochemical parameters were repeated after 4 weeks of treatment and an improvement was observed when iron was supplemented with folic acid. The effect of malnutrition and anaemia of pregnant moment was assessed on the birth weights of their newborns in 124 women. The newborns were divided in to 3 groups i.e. Small for age ( 3.5 Kg). The dietary history indicated a low intake of energy, protein and iron in mothers of small infants. On the basis of biochemical parameters it was concluded that the mothers were malnourished and anaemic which was more evident in mothers of small infants. The role of malabsorption was studied in 42 children suffering from malnutrition and anaemia and they were divided into 5 groups, i.e. fibrocystic disease of the pancreas. (n=9), coeliac disease (n=17), lactose intolerance (n=5), PEM (n=5) and non-specific diarrhea (n=6) on the basis of history, clinical impression and biochemical findings. Xylose and lactose tolerance tests were performed after oral dose of xylose or lactose respectively. The various biochemical indices studied indicate that malabsorption plays an important role in malnutrition and anaemia. (abstract only)

    2011-05-01

    Due to the non-stationary, multicomponent nature of biomedical signals, the use of time-frequency analysis can be inevitable for these signals. The choice and selection of the proper Time-Frequency Distribution (TFD) that can reveal the exact multicomponent structure of biological signals is vital in many applications, including the diagnosis of medical abnormalities. In this paper, the instantaneous frequency techniques using two distribution functions are applied for analysis of biological signals. These distributions are the Wigner-Ville Distribution and the Bessel Distribution. The simulation performed on normaland abnormal cardiac signals show that the Bessel Distribution can clearly detect the QRS complexes. However, Wigner-Ville Distribution was able to detect the QRS complexes in the normal signa, but fails to detect these complexes in the abnormal cardiac signal.

    Full Text Available Abstract Background We evaluated cytogenetic results occurring with first trimester pregnancy loss, and assessed the type and frequency of chromosomal abnormalities after assisted reproductive treatment (ART and compared them with a control group. We also compared the rate of chromosomal abnormalities according to infertility causes in ICSI group. Methods A retrospective cohort analysis was made of all patients who were referred to the Genetics Laboratory of Fertility Center of CHA Gangnam Medical Center from 2005 to 2009 because of clinical abortion with a subsequent dilation and evacuation (D&E performed, and patients were grouped by type of conception as follows: conventional IVF (in vitro fertilization (n = 114, ICSI (intracytoplasmic sperm injection (n = 140, and control (natural conception or intrauterine insemination [IUI] (n = 128. Statistical analysis was performed using SPSS software. 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

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

    Directory of Open Access Journals (Sweden)

    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.

    Full Text Available 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/Cl-8 and NGR/Cl-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.

    Full Text Available Abstract Background The aim of this study was to compare a gel-based test with the traditional direct agglutination test (DAT for the diagnosis of immune-mediated haemolytic anaemia (IMHA. Methods Canine (n = 247 and feline (n = 74 blood samples were submitted for DAT testing to two laboratories. A subset of canine samples was categorized as having idiopathic IMHA, secondary IMHA, or no IMHA. Results The kappa values for agreement between the tests were in one laboratory 0.86 for canine and 0.58 for feline samples, and in the other 0.48 for canine samples. The lower agreement in the second laboratory was caused by a high number of positive canine DATs for which the gel test was negative. This group included significantly more dogs with secondary IMHA. Conclusions The gel test might be used as a screening test for idiopathic IMHA and is less often positive in secondary IMHA than the DAT.

    Full Text Available ABSTRACT: Iron deficiency anaemia (IDA is the commonest medi cal disorder in pregnancy in developing countries including India. It is not only the leading cause of maternal death but also an aggravating factor in haemorrhage, sepsis and tox emia. Conditions such as abortions, premature births, antepartum haemorrhage, post partum haemorrhage and low birth weight were especially associated with low haemoglobin leve ls in pregnancy. 40 -80% of women belonging to low socio economic groups are anaemic i n the last trimester of pregnancy. Research on alternative to Iron Folic acid (IFA su pplementation is being carried out in some parts of India. Intravenous (IV Iron sucrose thera py is one such alternative. This study was planned to evaluate the response to intravenous iron sucrose in anaemic pregnant women from rural areas and compare it with oral iron therapy.

    Parvovirus B19 (PVB19) induced severe aplastic anaemia (SAA) or myelodysplastic syndrome (MDS) is rare, and haematopoietic stem cell transplantation (HSCT) in this condition has not been reported so far. 6 children with SAA (n=4) or MDS (n=2) caused by acute PVB19 infection underwent HSCT under the protection of intravenous immunoglobulines. The 4 children with SAA received matched HLA bone marrow from a sibling (n=3) or peripheral unrelated blood stem cells (n=1). 1 patient had delayed erythrocyte engraftment, whereas 3 patients had an uneventful transplantation course. HSCT in one of the 2 children with MDS was complicated by poor graft function, the other patient engrafted without complications. In conclusion, HSCT in children with PVB19 induced SAA or MDS is feasible, even though some patients may develop delayed engraftment or prolonged poor graft function. PMID:22052631

    Burn causes bone metabolic abnormality in most cases, including the changes in osteoblasts and osteoclasts, bone mass loss, and bone absorption, which results in decreased bone mineral density. These changes are sustainable for many years after burn and even cause growth retardation in burned children. The mechanisms of bone metabolic abnormality after burn include the increasing glucocorticoids due to stress response, a variety of cytokines and inflammatory medium due to inflammatory response, vitamin D deficiency, hypoparathyroidism, and bone loss due to long-term lying in bed. This article reviews the pathogenesis and regularity of bone metabolic abnormality after burn, the relationship between bone metabolic abnormality and burn area/depth, and the treatment of bone metabolic abnormality, etc. and discusses the research directions in the future.

    Full Text Available Background: Voluntary blood donation is promoted in order to make the blood banking safe and successful. Research in the area of blood donation has found that, iron stores are influenced by regular blood donation if dietary intake of iron is inadequate. Awareness and knowledge among blood donors regarding iron and B12 deficiency and its prevention is very much required. Objective: To assess the knowledge and awareness about iron deficiency and megaloblastic anaemia among blood donors. Methods: A cross sectional study was conducted among the 500 voluntary blood donors during the span of 1 year at one of the blood bank of tertiary care hospital using prestructured questionnaire on the various aspect of iron and B12 deficiency/folate deficiency anemia. The data was analysed with the help of Microsoft excel and SPSS. Results: Out of 500 blood donors, 15.6% donors were regular blood donor. It was observed 60% blood donors were having knowledge of anemia in general. Iron deficiency and vitamin B12 deficiency were known to 42% and 31.6% donors, respectively. Only 20% donors could able to answer the acceptable level of hemoglobin require for donating the blood. About 42% donors were aware about importance of iron, folate and vitamin B12 in maintaining normal hemoglobin level. Majority (82.7% of regular blood donors were willing to get information regarding iron, folate and vitamin B12 deficiency. Conclusion: Significant lack of awareness regarding iron and vitamin B12 deficiency was observed in regular voluntary blood donors. The present study recommends the provision of health education on iron and vitamin B12 deficiency as well as Iron, folate and vitamin B12 rich foods to regular blood donor to prevent anaemia among them.

    Full Text Available Introduction: in inflammatory bowel disease (IBD iron deficiency anaemia (IDA is a very common disorder. Until recently, oral iron has been the mainstay therapy, nevertheless it has been associated with intolerance and noncompliance. Therefore, the goal of our study was to evaluate the efficacy of intravenous iron in IDA in IBD patients and the secondary aim was to investigate whether other potential factors could influence in the response to the treatment. Design: an open-label, prospective, consecutive, single centre study. Material and methods: we performed our study in patients with ulcerative colitis (UC or Crohn's disease (CD with severe anaemia or intolerance with oral iron. All of them received intravenous sacarose iron and did biochemistry profile with haemoglobin (Hb. Moreover, the correlation with other variables was studied: age, sex, smoking habit, IBD type, previous surgery and type of surgery and other treatments. Response was defined as Hb increase of ≥ 2 g/dL or normalization of the levels. Results: fifty-four patients were included into the study, 34 (63% with UC y 20 (37% with CD, 18 (33.3% men and 36 women (66.6% and the average was 48 ± 14 years. The total proportion of responders was 52% (SD ± 05; 43% of the patients reached Hb ≥ 2 g/dl and y 9% of them normalized Hb. Only the utilization of 5-ASA was associated with low response to iron treatment (p < 0.05. Conclusions: our study suggests that response to intravenous iron is achievable in the majority of patients with IBD and severe IDA or intolerance treatment with oral iron. Moreover, the patients with consumption of 5-ASA could had less response to the treatment.

    Preimplantation genetic diagnosis (PGD) to select histocompatible siblings to facilitate curative haematopoeitic stem-cell transplantation (HSCT) is now an acceptable option in the absence of an available human leukocyte antigen (HLA) compatible donor. We describe a case where the couple who requested HLA-PGD, were both carriers of two serious haematological diseases, beta-thalassaemia and sideroblastic anaemia. Their daughter, affected with sideroblastic anaemia, was programmed to have HSCT. A multiplex-fluorescent-touchdown-PCR protocol was optimized for the simultaneous amplification of: the two HBB-gene mutated regions (c.118C> T, c.25-26delAA), four short tandem repeats (STRs) in chr11p15.5 linked to the HBB gene, the SLC25A38 gene mutation (c.726C > T), two STRs in chr3p22.1 linked to the SLC25A38 gene, plus eleven informative STRs for HLA-haplotyping (chr6p22.1-21.3). This was followed by real-time nested PCR and high-resolution melting analysis (HRMA) for the detection of HBB and SLC25A38 gene mutations, as well as the analysis of all STRs on an automatic genetic analyzer (sequencer). The couple completed four clinical in vitro fertilization (IVF)/PGD cycles. At least one matched unaffected embryo was identified and transferred in each cycle. A twin pregnancy was established in the fourth PGD cycle and genotyping results at all loci were confirmed by prenatal diagnosis. Two healthy baby girls were delivered at week 38 of pregnancy. The need to exclude two familial disorders for HLA-PGD is rarely encountered. The methodological approach described here is fast, accurate, clinically-validated, and of relatively low cost.

  11. Serum transferrin receptor, serum ferritin and serum transferrin receptor-ferritin index in adults with iron deficiency anaemia

    International Nuclear Information System (INIS)

    Bone marrow iron store has been considered the gold standard, but is invasive, painful and expensive and not suitable for everyone. serum transferrin receptor (stfr) which is the concentration of the soluble fragment of transferrin receptor in serum, is an important new haematological parameter. the ratio of stfr to log sf is known as stfr-sf index. this study was conducted to evaluate stfr, ferritin and stfr-f index in diagnosing and differentiating iron deficiency anaemia (ida) from anaemia of chronic disease (acd). methods: one hundred and sixteen (116) adult subjects (80 anaemic and 36 controls) who already had their bone marrow examination done for various reasons were included in the study. stfr, sf, and their index were measured and compared with bone marrow iron stores. absence of iron stores denoted ida whereas increased macrophage iron with decreased siderocytes and sideroblasts was diagnostic of acd. results: out of 80 anaemic patients, 47 were diagnosed as ida while 33 were diagnosed as acd. in case of ida the diagnostic accuracy of index was 91.57%, stfr had accuracy of 85.54% while sf had accuracy of 75.90%. in case of acd, the diagnostic accuracy of stfr was 91.30%, index 89.86%, while sf had accuracy of 79.71%. conclusion: stfr-sf index is a better parameter than stfr or ferritin alone but should only be used when the results of these parameters seem altered or a bone marrow aspiration is mandatory for diagnosis of acd. the estimation of stfr or index may offer a simple non invasive method that may enable more accurate assessments of iron status in such patients.

    2013-02-01

    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

  13. Intracranial CT abnormality associated with childhood leukemia

    International Nuclear Information System (INIS)

    We showed three abnormal CT findings of childhood leukemia. Case 1: A 3-year-old boy was found to have acute lymphocytic leukemia in January, 1980. Following prophylactic skull irradiation totaling 2,300 rad and 30 mg of intrathecal methotrexate, he was treated with oral and intravenous methotrexate (10-15 mg once weekly, totaling 2,035 mg). CT taken 2 years and 3 months after the onset showed fine, high-density spots in the left frontal, temporal, and bilateral parietal subcortical regions, without any contrast enhancement. The high-density spots were diagnosed as parenchymal calcification induced by the irradiation and methotrexate therapy. Case 2: A 5-year-old boy complaining of anemia and fever was diagnosed as having acute myelocytic leukemia and was treated with VAMP and DCVP. In March, 1982, he complained of severe headache, nausea, and vomiting 4.5 years after his onset. There were no neurological deficits nor any nuchal stiffness. A lumbar puncture showed increasing pressure of CSF over 250 mm H2O and a pleocytosis of the myeloblasts. CT showed an enhanced high-density mass in the pineal region and hydrocephalus. He improved and showed a normal CT after treatment with skull irradiation of 2,400 rad and four intraventricular injections of 15 mg methotrexate, 30 mg cytosine arabinoside, and 15 mg hydrocortisone via Ommaya's reservoir. Case 3: A 14-year-old boy who had suffered from acute lymphocytic leukemia, associated with meningeal infiltration, for 2 years and 10 months, complained of headache, disturbance of consciousness, and focal convulsion of the left upper limb in December, 1982. CT demonstrated multiple, round, high-density areas in the cerebral hemispheres. Those high-density areas were diagnosed as intracerebral leukemic masses and/or hemorrhages. After 1400 rad of skull irradiation and steroid therapy, the patient rallied shortly, but then expired. An autopsy was refused. (J.P.N.)

    Full Text Available Background: The Chromagen lens system comprises of tinted spectacle or contact lenses, each with a specific colour wavelength filter which controls the spectra of the light entering the eye. This study investigated whether spectacle-mounted Chromagen lenses would enhance colour perception in individuals with abnormal colour vision.Methods: The Ishihara colour test was used to test for colour vision deficiency (CVD and also to evaluate the effect of the Chromagen spectacle lens on colour perception in 13 subjects. An Oculus Anomaloscope was used to confirm and sub-classify the types of CVD. Subjects comprised of school age children from the Riyadh area in Saudi Arabia.Results: The distribution amongst the male participants comprised two subjects with protanomaly, two with protanopia, five with deuteranomaly, and two with deuteranopia. Amongst the two female participants, one subject showed deuteranomaly, and one showed protanomaly. Different types of Chromagen spectacle lenses displayed some levels of colour vision enhancement depending on type of CVD.Conclusion: The findings support the notion that chromagen lenses could enhance colour vision perception in some cases of red-green colour vision defects. Clients with CVD should be managed on an individual case basis. (S Afr Optom 2011 70(2 69-74 

  15. Dynamic simulation of variable capacity refrigeration systems under abnormal conditions

    International Nuclear Information System (INIS)

    There are often abnormal working conditions at evaporator outlet of a refrigeration system, such as two-phase state in transient process, and it is essential to investigate such transient behaviours for system design and control strategy. In this paper, a dynamic lumped parameter model is developed to simulate the transient behaviours of refrigeration system with variable capacity in both normal and abnormal working conditions. The appropriate discriminant method is adopted to switch the normal and abnormal conditions smoothly and to eliminate the simulated data oscillation. In order to verify the dynamic model, we built a test system with variable frequency compressor, water-cooling condenser, evaporator and electronic expansion valve. Calculated values from the mathematical model show reasonable agreement with the experimental data. The simulation results show that the transient behaviours of the variable capacity refrigeration system in the abnormal working conditions can be calculated reliably with the dynamic model when the compressor rotary speed or the opening of electronic expansion valve changes abruptly.

    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. PMID:25610779

    Sleep is essential. Unfortunately, a significant portion of the population experiences altered sleep states that often result in a multitude of health-related issues. The regulation of sleep and sleep-wake cycles is an area of intense research, and many options for treatment are available. The following review summarizes the current understanding of normal and abnormal sleep-related conditions and the available treatment options. All clinicians managing patients must recommend appropriate therapeutic interventions for abnormal sleep states. Clinicians' solid understanding of sleep physiology, abnormal sleep states, and treatments will greatly benefit patients regardless of their disease process. PMID:22778676

    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.

    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.)

  1. Abnormal parietal function in conversion paresis.

    Directory of Open Access Journals (Sweden)

    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.

  2. Update: consequences of abnormal fetal growth.

    2012-03-01

    Intrauterine growth restriction (IUGR) is prevalent worldwide and affects children and adults in multiple ways. These include predisposition to type 2 diabetes mellitus, the metabolic syndrome, cardiovascular disease, persistent reduction in stature, and possibly changes in the pattern of puberty. A review of recent literature confirms that the metabolic effects of being born small for gestational age are evident in the very young, persist with age, and are amplified by adiposity. Furthermore, the pattern of growth in the first few years of life has a significant bearing on a person's later health, with those that show increasing weight gain being at the greatest risk for future metabolic dysfunction. Treatment with exogenous human GH is used to improve height in children who remain short after being small for gestational age at birth, but the response of individuals remains variable and difficult to predict. The mechanisms involved in the metabolic programming of IUGR children are just beginning to be explored. It appears that IUGR leads to widespread changes in DNA methylation and that specific "epigenetic signatures" for IUGR are likely to be found in various fetal tissues. The challenge is to link such alterations with modifications in gene expression and ultimately the metabolic abnormalities of adulthood, and it represents one of the frontiers for research in the field.

  3. Gray matter volumetric abnormalities associated with the onset of psychosis

    Wi Hoon eJung

    2012-12-01

    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.

    BACKGROUND Conotruncal heart defects comprise 25%-30% of non-syndromic congenital heart defects. This study describes the frequency of chromosome abnormalities and microdeletion 22q11 associated with conotruncal heart malformations. METHODS From a population base of 974,579 infants/fetuses delivered, 622 Californian infants/fetuses were ascertained with a defect of aortico-pulmonary septation. Infants whose primary cardiac defect was tetralogy of Fallot (n=296) or D-transposition of the great vessels (n=189) were screened for microdeletions of 22q11. RESULTS Fourteen (2.3%) of the 622 infants/fetuses had chromosomal abnormalities. Thirty infants, 10% of those whose primary defect was tetralogy of Fallot, had chromosome 22q11 microdeletions. Right aortic arch, abnormal branching patterns of the major arteries arising from the thoracic aorta, and pulmonary artery abnormalities were observed more frequently in these children. CONCLUSIONS We found an unusual number of infants with an extra sex chromosome and a conotruncal defect. Infants with tetralogy of Fallot due to 22q11 microdeletion showed more associated vascular anomalies than infants with tetralogy but no 22q11 microdeletion. Although these associated vascular anomalies provide clues as to which infants with tetralogy of Fallot are more likely to carry the microdeletion, the overall risk of 10% among all infants with tetralogy of Fallot warrants chromosome analysis and FISH testing routinely.

    Epileptic seizure control and the disappearance of epileptiform discharge are not indicative of the absence of abnormal perfusion foci.Perfusion abnormalities are a major cause of epileptic discharge, and the existence of abnormal perfusion foci implies possible relapse.Very little is known about perfusion abnormality repair in epilepsy.The present study selected 43 cases of idiopathic epilepsy under antiepileptic drug control for an average of 24 months.Comparisons between interictal single-photon emission CT (SPECT)images and long-term electroencephalogram (EEG) pre- and post-treatment showed that cases of normal SPECT increased by 48% (12/25) following treatment, with a total number of 15 reduced foci (36%, 15/41).Perfusion foci, i.e., region of interest, were altered following treatment.These changes included:normal to abnormal in 3 cases (7%, 3/43; 2 hyperperfusion and 1 hypoperfusion); abnormal to normal in 14 cases (32%, 14/43; 10 pre-treatment hypoperfusion and 4 hyperperfusion); abnormal to abnormal in 7 cases (16%, 7/43; hyperperfusion to hypoperfusion in 5 cases, hypoperfusion to hyperperfusion in 2 cases).Long-term EEG revealed in an increase in the number of normal cases by 20 (40%, 20/39), and there were 25 fewer cases with epileptiform discharges (66%, 25/38).These findings demonstrate that long-term control of anti-epileptic drugs partially repaired cerebral perfusion abnormalities and reduced epileptiform discharges in idiopathic epilepsy.

  6. Abnormal ventilation scans in middle-aged smokers. Comparison with tests of overall lung function

    International Nuclear Information System (INIS)

    The uniformity of regional ventilation during tidal breathing has been assessed using continuous inhalation of krypton-81m in 43 male, lifelong nonsmokers and 46 male, current cigarette smokers (mean daily consumption 24.1 cigarettes/day) between 44 and 61 yr of age and with mild or no respiratory symptoms. All subjects had normal chest radiographs. The results of the ventilation scans were compared with tests of overall lung function (spirometry, maximal expiratory flow-volume curves, and single-breath N2 test). Diffuse abnormalities of the ventilation scan were found in 19 (41%) of the 46 smokers but in none of the nonsmokers. Focal abnormalities were found in 7 smokers and 3 nonsmokers. Smokers showed the expected abnormalities in overall lung function (reduced FEV1 and VC, increased single-breath N2 slope, and closing volume), but in individual smokers there was only a weak relation between the severity of abnormality of overall lung function and an abnormal ventilation scan. Abnormal scans could be found when overall lung function was normal and were not invariably found when significant abnormalities in FEV1/VC or N2 slope were present. There was no relation between the presence of chronic expectoration and an abnormal scan. The prognostic significance of an abnormal ventilation scan in such smokers remains to be established

    Full Text Available Abstract Background Pathological gambling (PG is an impulse control disorder characterized by persistent and maladaptive gambling behaviors with disruptive consequences for familial, occupational and social functions. The pathophysiology of PG is still unclear, but it is hypothesized that it might include environmental factors coupled with a genetic vulnerability and dysfunctions of different neurotransmitters and selected brain areas. Our study aimed to evaluate a group of patients suffering from PG by means of some neuropsychological tests in order to explore the brain areas related to the disorder. Methods Twenty outpatients (15 men, 5 women, with a diagnosis of PG according to DSM-IV criteria, were included in the study and evaluated with a battery of neuropsychological tests: the Wisconsin Card Sorting Test (WCST, the Wechsler Memory Scale revised (WMS-R and the Verbal Associative Fluency Test (FAS. The results obtained in the patients were compared with normative values of matched healthy control subjects. Results The PG patients showed alterations at the WCST only, in particular they had a great difficulty in finding alternative methods of problem-solving and showed a decrease, rather than an increase, in efficiency, as they progressed through the consecutive phases of the test. The mean scores of the other tests were within the normal range. Conclusion Our findings showed that patients affected by PG, in spite of normal intellectual, linguistic and visual-spatial abilities, had abnormalities emerging from the WCST, in particular they could not learn from their mistakes and look for alternative solutions. Our results would seem to confirm an altered functioning of the prefrontal areas which might provoke a sort of cognitive "rigidity" that might predispose to the development of impulsive and/or compulsive behaviors, such as those typical of PG.

    The aim of this study was to investigate and describe the range of white matter abnormalities in children with tuberous sclerosis complex by means of MR imaging. Material and Methods: A retrospective cross-sectional study was performed on the basis of MR imaging findings in 20 cases of tuberous sclerosis complex in children aged 17 years or younger. Results: White matter abnormalities were present in 19/20 (95%) cases of tuberous sclerosis complex. These were most frequently (19/20 cases) found in relation to cortical tubers in the supratentorial compartment. White matter abnormalities related to tubers were found in the cerebellum in 3/20 (15%) cases. White matter abnormalities described as radial migration lines were found in relation to 5 tubers in 3 (15%) children. In 4/20 (20%) cases, white matter abnormalities were found that were not related to cortical tubers. These areas had the appearance of white matter cysts in 3 cases and infarction in the fourth. In the latter case there was a definable event in the clinical history, supporting the diagnosis of stroke. Conclusion: A range of white matter abnormalities were found by MR imaging in tuberous sclerosis complex, the commonest being gliosis and hypomyelination related to cortical tubers. Radial migration lines were seen infrequently in relation to cortical tubers and these are thought to represent heterotopic glia and neurons along the expected path of cortical migration. (orig.)

Bacteraemia was present in 43 admissions (4·8%); isolates included Staphylococcus aureus (12/43; 28%), non‐Typhi Salmonella (9/43; 21%), Streptococcus pneumoniae (3/43; 7%) and Salmonella Typhi (2/43; 5%). Compared to SCA patients without bacteraemia, SCA patients with bacterae...

    Disseminated fusariosis is a life-threatening, invasive, opportunistic infection in immunocompromised patients, especially those with haematological malignancies. The prognosis is poor because these fungi are resistant to many of the available antifungal agents. We present a case of disseminated fusariosis caused by Fusarium proliferatum in a patient with severe aplastic anaemia complicated by a secondary infection of Aspergillus flavus, with a fatal outcome. We also review the documented Fusarium infections in immunocompromised hosts. PMID:26661324

    Chronic haemolysis stands out as one of the hallmarks of sickle cell anaemia, a clinically heterogeneous autosomal recessive monogenic anaemia. However, the genetic architecture of this sub-phenotype is still poorly understood. Here, we report the results of an association study between haemolysis biomarkers (serum LDH, total bilirubin and reticulocyte count) and the inheritance of 41 genetic variants of ten candidate genes in a series of 99 paediatric SS patients (median current age of 9.9 yr) followed up in two general hospitals in Greater Lisboa area (median follow-up per patient of 5.0 yr). Although in a large number of tests a seemingly significant (i.e. P haplotype 7 within VCAM1 gene; (ii) a lower total bilirubin was associated with the 3.7-kb deletion at HBA gene, rs2070744_T allele at NOS3 gene, and haplotype 9 within VCAM1 promoter; and (iii) a diminished reticulocyte count was associated with the 3.7-kb deletion at HBA, whereas an increased count was associated with rs1984112_G allele at CD36 gene. On the whole, our findings suggest a complex genetic architecture for the sickle cell anaemia haemolysis process involving multiple pathways, namely control of vascular cell adhesion, NO synthesis and erythrocyte volume and haemoglobinisation.

  15. Ferrochelatase deficiency of the bone marrow in a syndrome of congenital microcytic anaemia with iron overload of the liver and hyperferraemia

    International Nuclear Information System (INIS)

    By far the most common mechanisms for hypochromic anaemias are either iron deficiency with a limited production of haem or the thalassaemias with a limited production of peptide chains. Some extremely rare congenital hypochromic anaemias have also been reported, in which iron deficiency or thalassaemia is not the cause. One of them is atransferrinaemia. In another rare type of hereditary, congenital hypochromic anaemia, the patients have hyperferraemia with a near fully saturated total iron binding capacity. In spite of heavy haemosiderin deposits in the liver, the bone marrow haemosiderin is reduced. In our studies which where reported in 1983, we found normal transferrin, Hb electrophoresis was normal, and there were no findings indicating thalassaemia minor or lead intoxication. We suggested that the most likely explanation of the condition was a defect in the iron transport mechanism from transferrin into the erythroid cells in the bone marrow, but at that time we had no method for studying this. During the last few years, more reliable methods have become available for assaying ferrochelatase, the enzyme largely responsible for the incorporation of iron into haem. We have therefore repeated our previous studies (with essentially the same results as reported in 1973), and have also assayed ferrochelatase activity of the bone marrow. (author)

    Full Text Available Abstract The incidence and mortality of pancreatic adenocarcinoma are nearly coincident having a five-year survival of less than 5%. Enormous advances have been made in our knowledge of the molecular alterations commonly present in ductal cancer and other pancreatic malignancies. One significant outcome of these studies is the recognition that common ductal cancers have a distinct molecular fingerprint compared to other nonductal or endocrine tumors. Ductal carcinomas typically show alteration of K-ras, p53, p16INK4, DPC4 and FHIT, while other pancreatic tumor types show different aberrations. Among those tumors arising from the exocrine pancreas, only ampullary cancers have a molecular fingerprint that may involve some of the same genes most frequently altered in common ductal cancers. Significant molecular heterogeneity also exists among pancreatic endocrine tumors. Nonfunctioning pancreatic endocrine tumors have frequent mutations in MEN-1 and may be further subdivided into two clinically relevant subgroups based on the amount of chromosomal alterations. The present review will provide a brief overview of the genetic alterations that have been identified in the various subgroups of pancreatic tumors. These results have important implications for the development of genetic screening tests, early diagnosis, and prognostic genetic markers.

    beta thalassaemia, both in heterozygous state. Overall, the prevalence of abnormal haemoglobins was found to be higher among negroids (7.68% than among the caucasoids (3.02%, and this difference was statistically significant (x²1; 0.01 = 6.64 x²1; 0.05 = 3.84. While the overall prevalence of abnormal haemoglobins among the S. José do Rio Preto subjects did not differ from prevalence among Presidente Prudente subjects, the prevalence of the genotypes detected among the populations analysed of these two cities, and their respective regions, was different. For S. José do Rio Preto and region, the Hb AS was more prevalent among the abnormal haemoglobins (63%, next came heterozygous beta thalassaemia (17%. For Presidente Prudente the prevalences of Hb AS and heterozygous beta thalassaemia, among the abnormal haemoglobins, were 46% and 40%, respectively. The preventive action to be taken was established by means of meetings at which medical and biological explanations were given to the carriers of abnormal haemoglobins. Overall, the results showed that similar studies offer better knowledge of genetic, biochemical and haemotological causes of these hereditary anaemias, and also provide the opportunity of discovering the importance that these pathological states have in the public health of the Brazilian population.

    To determine whether abnormalities of pulmonary surfactant occur in infants with acute viral bronchiolitis, surfactant indices were measured in lung lavage fluid from 12 infants with severe bronchiolitis and eight infants without lung disease. Compared with controls, the bronchiolitis group showed deficiency of surfactant protein A (1.02 v 14.4 micrograms/ml) and disaturated phosphatidylcholine (35 v 1060 micrograms/ml) which resolved as the disease improved.

    Full Text Available Abstract Background Severe tooth decay is known to affect the health and well-being of young children. However, little is known about the influence of Severe Early Childhood Caries (S-ECC on childhood nutritional status. The purpose of this study was to contrast ferritin and haemoglobin levels between preschoolers with S-ECC and caries-free controls. Methods Children were recruited as part of a larger case–control study examining differences in nutritional status between those with and without S-ECC. Preschoolers with S-ECC were recruited on the day of their dental surgery, while caries-free controls were recruited from the community. Parents completed a questionnaire and the child underwent venipuncture. The study was approved by the University’s Health Research Ethics Board. Statistics included descriptive, bivariate and logistic regression analyses. A p value ≤ .05 was significant. A total of 266 children were recruited; 144 with S-ECC and 122 caries-free. Results The mean age was 40.8 ± 14.1 months. The mean ferritin concentration for all children was 29.6 ± 17.9 μg/L while the mean haemoglobin level was 115.1 ± 10.1 g/L. Children with S-ECC were significantly more likely to have low ferritin (p=.033 and low haemoglobin levels (p>.001. Logistic regression analyses revealed that children with S-ECC were nearly twice as likely to have low ferritin levels and were over six times more likely to have iron deficiency anaemia than caries-free controls. Conclusions Children with S-ECC appear to be at significantly greater odds of having low ferritin status compared with caries-free children and also appear to have significantly lower haemoglobin levels than the caries-free control group. Children with S-ECC also appear to be at significantly greater odds for iron deficiency anaemia than cavity-free children.

  20. Incidence of abnormal retropharyngeal lymph nodes in sinonasal malignancies among adults

    International Nuclear Information System (INIS)

    The aim of this study is to investigate the relationship between abnormal retropharyngeal lymph nodes (RPLNs) and sinonasal malignancies among adults. Magnetic resonance and computed tomography images from 89 patients over 20 years old who were all histopathologically confirmed to have sinonasal malignancies from September 2001 to April 2014 were assessed retrospectively. Abnormal RPLNs were determined as those >5 mm in shortest axis or showing heterogeneous enhancement on axial images. Locations of sinonasal malignancies were categorized using the anterior border of the pterygopalatine fossa as a boundary: (a) anterior lesions, only present anterior to the boundary, or (b) posterior lesions, present or extending posterior to the boundary. Fisher's exact test was used for the analysis of the relationship between frequency of abnormal RPLNs and lesion location. Abnormal RPLNs were present in 13 of 89 patients (15 %), including 6 of 41 squamous cell carcinomas (15 %), 4 of 24 malignant lymphomas (17 %), 3 of 5 olfactory neuroblastomas (60 %), and 0 of 19 others (0 %). Four of the 39 patients (10 %) with anterior lesions showed abnormal RPLNs, compared to 9 of 50 patients (18 %) with posterior lesions. No significant difference in frequency of abnormal RPLNs was apparent between anterior and posterior lesions (P = 0.37). In primary sinonasal malignancies among adults, the highest incidence of abnormal RPLNs was seen with olfactory neuroblastoma. The frequency of abnormal RPLNs was unaffected by the location of sinonasal malignancies among adults. (orig.)
