Intrathoracic extramedullary haematopoiesis complicated by massive haemothorax in alpha-thalassaemia. (1/220)

Intrathoracic extramedullary haematopoiesis (EMH) is a rare entity that is usually asymptomatic. A 44 year old man with alpha-thalassaemia is described who developed dyspnoea and massive left sided haemothorax. The haemoglobin disorder was established by Hgb H staining and haemoglobin electrophoretic studies. The DNA analysis revealed it to be a case of double heterozygous terminal codon mutation with the genotype alphaalphaCS/alphaalphaT. Computed tomographic scanning and magnetic resonance imaging of the thorax showed multiple paravertebral masses which were found by thoracoscopic biopsy to be extramedullary haematopoiesis. Although no additional sclerosing pleurodesis or low dose radiation therapy was given, the lung expanded well and there has been no recurrence of haemothorax to date.  (+info)

Relapse in chronic myeloid leukemia after bone marrow transplantation: biomathematical modeling as a new approach to understanding pathogenesis. (2/220)

A biomathematical model was developed to simulate relapse development in patients with chronic myeloid leukemia (CML) following bone marrow transplantation (BMT). The purpose of this study was to better understand the pathophysiology of the time evolution of CML relapse and to provide means whereby the outcomes of patients with CML relapse can be projected and treatment modified accordingly. The model consists of three parallel series of catenated compartments representing granulopoiesis in normal (donor) cells from the marrow, in CML cells from the marrow, and in CML cells from extramedullary sites. It was assumed that CML stem cells were resistant to feedback control and that CML-derived neutrophils, as well as normal neutrophils, exercised feedback regulation of normal stem cells. The known longer generation times for CML neutrophil precursors compared with normal neutrophil precursors were used, and it was assumed that 10(7) pluripotential stem cells were infused with BMT. The model was evaluated for its ability to simulate the reappearance of CML (Philadelphia chromosome positive) metaphases in the marrow and the recovery pattern in the blood neutrophil count in six patients who had relapsed following BMT (allogeneic in three patients, allogeneic with T-cell depletion in two patients, and syngeneic in one patient). The variables tested included the site of origin of the CML stem cells responsible for relapse (marrow alone versus marrow and extramedullary sites), the minimum number of CML stem cells responsible for relapse, and the time delay between BMT and the onset of relapse. Model profiles based on the observed values were obtained in each case. The simulations pointed to the fact that relapse began from a small number of CML cells in medullary and extramedullary sites. The time delay between BMT and the onset of relapse varied from 15 to 240 days. We suggest that this biomathematical model should be further investigated as a possible means of predicting outcome and guiding the treatment for patients with CML relapsing after BMT.  (+info)

Extramedullar B lymphopoiesis in liver schistosomal granulomas: presence of the early stages and inhibition of the full B cell differentiation. (3/220)

Inflammatory granulomatous reactions in liver elicited by schistosomal infection have been shown to function as active extramedullar myelopoietic sites, producing potentially all the myeloid lineages. We have now addressed the question of the extramedullar B lymphopoiesis in these sites. We have shown the presence of early B cell precursors (pro-B cells) in the granulomas by immunophenotyping. Their total number in the liver was equivalent to the pro-B cells in the bone marrow of one femur. In agreement with their phenotype, the RT-PCR analysis showed that these cells expressed RAG-1 and lambda5 genes. However, the conversion of the pro-B to pre-B cells was not observed and no clonogenic B cell precursors could be detected in semi-solid cultures stimulated by IL-7. The granulomatous stroma was shown to produce IL-7 and express c-kit, and was able to sustain the full B lymphopoiesis in vitro. Conversely, the granuloma supernatant was shown to inhibit actively the development of B lymphocytes. We conclude that the granuloma environment elicits homing and proliferation of totipotent hematopoietic precursors, and that it is permissive for early commitment to the B cell lineage, but the full extramedullar production of B cell is abrogated by soluble factors produced inside the granulomas.  (+info)

Enhanced autoimmune arthritis in IFN-gamma receptor-deficient mice is conditioned by mycobacteria in Freund's adjuvant and by increased expansion of Mac-1+ myeloid cells. (4/220)

Induction of experimental autoimmune diseases often relies on immunization with the organ-specific autoantigens in CFA, which contains heat-killed mycobacteria. In several of these models, including collagen-induced arthritis, endogenous IFN-gamma acts as a disease-limiting factor in the pathogenesis of the disease. Here we show that in collagen-induced arthritis the protective effect of IFN-gamma depends on the presence of mycobacteria in the adjuvant. Omission of mycobacteria inverts the role of endogenous IFN-gamma to a disease-promoting factor. Thus, the mycobacterial component of CFA opens a pathway by which endogenous IFN-gamma exerts a protective effect that supersedes its otherwise disease-promoting effect. Extramedullary hemopoiesis and expansion of the Mac-1+ cell population accompanied the accelerated and more severe disease course in the IFN-gamma receptor knockout mice immunized with CFA. Treatment of such mice with Abs against the myelopoietic cytokines IL-6 or IL-12 inhibited both disease development and the expansion of the Mac-1+ population. We postulate that mycobacteria in CFA stimulate the expansion of the Mac-1+ cell population by a hemopoietic process that is restrained by endogenous IFN-gamma. These results have important implications for the validity of animal models of autoimmunity to study the pathogenesis and to evaluate cytokine-based therapy of autoimmune diseases.  (+info)

RANK is essential for osteoclast and lymph node development. (5/220)

The physiological role of the TNF receptor (TNFR) family member, RANK, was investigated by generating RANK-deficient mice. RANK(-/-) mice were characterized by profound osteopetrosis resulting from an apparent block in osteoclast differentiation. RANK expression was not required for the commitment, differentiation, and functional maturation of macrophages and dendritic cells from their myeloid precursors but provided a necessary and specific signal for the differentiation of myeloid-derived osteoclasts. RANK(-/-) mice also exhibited a marked deficiency of B cells in the spleen. RANK(-/-) mice retained mucosal-associated lymphoid tissues including Peyer's patches but completely lacked all other peripheral lymph nodes, highlighting an additional major role for RANK in lymph node formation. These experiments reveal that RANK provides critical signals necessary for lymph node organogenesis and osteoclast differentiation.  (+info)

Increased fetal and extramedullary hematopoiesis in Fas-deficient C57BL/6-lpr/lpr mice. (6/220)

In this study, we examined the consequences of Fas deficiency on hematopoiesis in C57BL/6-lpr/lpr mice. We found a striking extramedullary increase in hematopoietic progenitor cells, comprising erythroid and nonerythroid lineages alike. These modifications preceded the lymphadenopathy, because early progenitors (colony-forming units-spleen [CFU-S] day 8) were already augmented in day-18 fetal livers of the lpr phenotype. Three weeks after birth, CFU-S increased in peripheral blood and spleen and colony-forming cells (CFU-C) began to accumulate 1 to 3 weeks later. Extramedullary myelopoiesis augmented progressively in Fas-deficient mice, reaching a maximum within 6 months. By then, mature and immature myeloid cells had infiltrated the spleen, the liver, and the peritoneal cavity. Similar changes occurred in C57BL/6-gld/gld mice, indicating that they resulted from Fas/FasL interactions. Medullary hematopoiesis was not significantly modified in adult mice of either strain. Yet, the incidence of CFU-S decreased after Fas cross-linking on normal bone marrow cells in the presence of interferon gamma, consistent with a regulatory function of Fas/FasL interactions in early progenitor cell development. These data provide evidence that Fas deficiency can affect hematopoiesis both during adult and fetal life and that these modifications occur independently from other pathologies associated with the lpr phenotype.  (+info)

The glucocorticoid receptor is required for stress erythropoiesis. (7/220)

The glucocorticoid receptor (GR) coordinates a multitude of physiological responses in vivo. In vitro, glucocorticoids are required for sustained proliferation of erythroid progenitors (ebls). Here, we analyze the impact of the GR on erythropoiesis in vivo, using GR-deficient mice or mice expressing a GR defective for transactivation. In vitro, sustained proliferation of primary ebls requires an intact GR. In vivo, the GR is required for rapid expansion of ebls under stress situations like erythrolysis or hypoxia. A particular, GR-sensitive progenitor could be identified as being responsible for the stress response. Thus, GR-mediated regulation of ebl proliferation is essential for stress erythropoiesis in vivo.  (+info)

Alpha4 integrins regulate the proliferation/differentiation balance of multilineage hematopoietic progenitors in vivo. (8/220)

We investigated roles of alpha4 integrins during hematopoiesis using mutant and chimeric mice. Yolk sac erythropoiesis and migration of hematopoietic progenitors to fetal liver, spleen, and bone marrow can occur without alpha4 integrins. Although terminal differentiation of these progenitors is possible without alpha4 integrins, these receptors are essential to maintain normal hematopoiesis in fetal liver, spleen, and bone marrow microenvironments. Moreover, alpha4-deficient erythroid progenitors and pre-B cells neither transmigrate beneath the stroma nor expand-properly in vitro. In contrast, alpha4-null cells migrate and differentiate efficiently into T lymphocytes within the thymus. In summary, alpha4 integrins are essential for normal development of all hematopoietic lineages in fetal liver, bone marrow, and spleen, likely by regulating the proliferation/differentiation balance of hematopoietic progenitors.  (+info)

Main myelofibrosis (PMF) commonly results in extramedullary hematopoiesis (EMH) in the spleen and liver as well as a variety of additional organs. biopsy exposed a hypercellular marrow moderately improved reticulin fibrosis and features consistent with main myelofibrosis. Abdominal imaging showed a normal-size spleen and did not determine any sites of EMH outside of the liver. The analysis of myelofibrosis was therefore made and this case shown predominant tropism to a transplanted freebase liver graft with absence of EMH elsewhere. We would therefore like to emphasize that findings of EMH in subjects with no preexisting hematologic neoplasm should warrant close follow-up and assessment. 1 Introduction Classified like a BCR-ABL bad myeloproliferative neoplasm [1] myelofibrosis is definitely a clonal cell malignancy characterized by progressive bone marrow fibrosis and ineffective erythropoiesis [2]. Extramedullary hematopoiesis is definitely a well-recognized trend of this disease process. ...
Extramedullary hematopoiesis (EMH) can occur in many disorders including thalassemias, polycythemia rubra vera, myelofibrosis, hemolytic anemia and other hemoglobinopathies. Spinal cord compression due to EMH in thalassemia was first reported by Gatto in 1954.2 It usually has a predilection for the lower thoracic spine where the limited mobility and narrow spinal canal predisposes itself to spinal cord compression.3,6 Most cases present with paraparesis, sensory impairment and occasionally sphincter disturbances. Complete paraplegia has been reported very rarely in thalassemia and occurs more frequently in polycythemia rubra vera and sickle cell anemia.1 The diagnostic procedure of choice is magnetic resonance imaging (MRI) which characteristerically shows an isointense mass with a high spinal intensity rim on T1-weighted images and a hyperintense mass on T2-weighted images.4 The diagnosis is based on strong clinical suspicion in the presence of diffuse bone marrow hyperplasia along with ...
Extramedullary haematopoiesis (EMH) is a rare cause of spinal cord compression. When a patient with a haematological disorder that causes chronic anaemia (particularly thalassaemia) presents with neurological deficits referable to the spine, EMH with paraspinal masses should be considered and imaging planned appropriately.
A 24-year-old female with haemoglobin E-thalassaemia who presented with paraparesis of 18 months duration was found to have spinal extradural extramedullary haemopoietic tissue extending from T4 to T9. Complete neurological recovery followed laminectomy. The importance of prompt diagnosis and treatment, of this unusual complication of extramedullary haemopoiesis, before the spinal cord is irreversibly damaged is stressed.. ...

Trilinear hematopoiesis (TH) can occur in thyroidal aspirations by one of three mechanisms: as mass-forming extramedullary hematopoiesis (EMH), as marrow elements within thyroidal metaplastic bone or as marrow elements in aspirated ossified neck cartilage. Extramedullary hematopoiesis is a dynamic process of blood cell development occurring outside the confines of the medullary cavity of bone often in the settings of hypoxia, inflammation and bone marrow failure. Several case reports exist of EMH in various organs mimicking a mass and being discovered on fine needle aspiration. Although liver, spleen and lymph nodes are the most common sites, thyroid EMH can also occur. In a 2008 review, Westhoff et al. found that EMH of the thyroid most often occurs in older patients and is most likely secondary to a myelophthisic disease, such as myelofibrosis or metastatic bone marrow disease. Some reported cases of EMH in the thyroid have been attributable only to chronic anemia and still other cases have ...
Ectopic extramedullary hematopoiesis (EMH), defined as the formation of blood cells outside the bone marrow, usually occurs in a scenario of chronic anemia when, even after conversion of the bony yellow marrow to red marrow, the body is still unable to meet the demand for red blood cells. Ectopic extramedullary hematopoiesis most commonly occurs in the liver and spleen but may, in fact, occur almost anywhere in the body. Although previous reports have documented EMH presenting as paraspinal masses, such lesions have almost always been associated with a predisposing hematological disorder such as hemolytic anemia, myelofibrosis or myelodysplastic syndromes, thalassemia, polycythemia vera, leukemia, or lymphoma.. The authors of this report describe the first reported instance of EMH in a patient presenting with a symptomatic epidural and paraspinal cervical lesion arising from the posterior spinal elements and no known predisposing hematological disease. Initial radiographs revealed a bony lesion ...
Cancer progression is associated with alterations of intra- and extramedullary hematopoiesis to support a systemic tumor-promoting myeloid response. However, the functional specialty, mechanism, and clinical relevance of extramedullary hematopoiesis (EMH) remain unclear. Here, we showed that the heightened splenic myelopoiesis in tumor-bearing hosts was not only characterized by the accumulation of myeloid precursors, but also associated with profound functional alterations of splenic early hematopoietic stem/progenitor cells (HSPCs). With the distinct capability to produce and respond to granulocyte-macrophage CSF (GM-CSF), these splenic HSPCs were primed and committed to generating immunosuppressive myeloid cells. Mechanistically, the CCL2/CCR2 axis-dependent recruitment and the subsequent local education by the splenic stroma were critical for eliciting this splenic HSPC response. Selective abrogation of this splenic EMH was sufficient to synergistically enhance the therapeutic efficacy of ...
DIAGNOSIS Multiple intracranial meningeal extramedullary hematopoiesis DISCUSSION EMH occurs as a compensatory mechanism in a variety of disorders characterized by a chronic hematopoietic deficit such as thalassemia major and intermedia, congenital spherocytosis and sickle cell anemia, and bone marrow dysfunction seen in myelofibrosis and carcinomatosis. Lymphoma and leukemia can also result in EMH. Intracranial EMH is rare. The pathway of EMH involvement of the dura is unknown, but it is postulated that the dura has hematopoietic capacity in the fetus and EMH may originate from primitive rests. In addition, the epidural space is a potential space that can harbor metastatic or heterotopic tissue deposits. Various hypotheses exist to explain the development of hemopoietic tissue to supplement marrow production. Lyall [8] proposed the possibility of direct extension from marrow into epidural space. Knoblich [4] proposed that multipotential cells in the epidural space can be transformed into marrow ...

EMH: what on earth is Kling talking about? He says: Consider financial variables, such as the long-term interest rate or the price-earnings ratio of the overall stock market. According to the efficient markets hypothesis, these are not predictable on the basis of known information. You might find quotes from the 60s or 70s saying something like this, but the modern interpretation, I think, is simply that information is reflected in asset prices. That still leaves things like risk premiums to move around in predictable ways. Theres no end of working trying to do this in both finance and macro. I read the whole post (Klings, I mean), and with due respect to his offer to take the most charitable view of those who disagree, Id have to say the post is more confusing than helpful. Is that charitable enough, or do I need to work on it a bit more? ...
Hematopoietic stem cell (HSC) niches in bone marrow have been described in terms of distinct cell types including osteoblastic, endothelial and perivascular reticular cells. However, niches which support extramedullary hematopoiesis in other sites like spleen remain to be elucidated. Previous studies have described splenic stromal cells which support hematopoiesis in vitro from purified HSC and multipotential progenitors (MPP) leading to the production of dendritic-like cells. Stromal cell lines were originally derived from splenocyte cultures, and later as freshly isolated stromal subsets prepared by enzymatic digestion and sorting. Transcriptome analysis has revealed that stroma which support hematopoiesis express many genes in parallel with perivascular cells described in bone marrow. They share a common mesenchymal lineage with perivascular cells in bone marrow, as well as mesenchymal progenitor cells and CXCL12-abundant reticular cells. They reflect osteoprogenitors in that cells can be induced to
Two studies by Walkley et al. investigated the role of intrinsic and extrinsic factors in regulating cell cycle and fate of hematopoietic stem cells (HSCs), which reside in specialized niches in the bone marrow and give rise to the cells of the hematopoietic system (see Perry and Li). Although most HSCs maintain a relatively quiescent state, they can be stimulated to enter the cell cycle when hematopoiesis is required. The retinoblastoma (RB) tumor suppressor plays a critical role in cell cycle regulation and, in the first study, Walkley et al. examined the effects of Rb deletion on hematopoiesis. Widespread loss of RB throughout the mouse hematopoietic system led to profound myeloproliferation, characterized by an increase in the numbers of circulating progenitor cells and extramedullary hematopoiesis. There was a loss of trabecular bone (a HSC niche) and HSCs from the bone marrow, and eventual hematopoietic failure. When RB loss was restricted to cells of the myeloid lineage (granulocytes, ...
Affected dogs usually present with a normocytic, normochromic nonregenerative anemia, neutropenia and thrombocytopenia. Diagnosis requires multiple bone marrow core biopsies and histological examination of other organ tissue samples, confirming the increased presence of fibrosis within bone marrow spaces and increased extramedullary hematopoiesis in other organs such as the liver and spleen. There is no specific treatment for this condition apart from long-term prednisolone, erythropoietin and addressing the underlying cause of this disease. In severely anemic dogs, whole blood transfusions of fresh frozen plasma may be required as a palliative strategy to forestall a demise. Development of new protein kinase inhibitors has shown promise at treating myelofibrosis secondary to lymphoma[13]. ...
Oncogenic ras alleles are among the most common mutations found in patients with acute myeloid leukemia (AML). Previously, the role of oncogenic ras in cancer was assessed in model systems overexpressing oncogenic ras from heterologous promoters. However, there is increasing evidence that subtle differences in gene dosage and regulation of gene expression from endogenous promoters play critical roles in cancer pathogenesis. We characterized the role of oncogenic K-ras expressed from its endogenous promoter in the hematopoietic system using a conditional allele and IFN-inducible, Cre-mediated recombination. Mice developed a completely penetrant myeloproliferative syndrome characterized by leukocytosis with normal maturation of myeloid lineage cells; myeloid hyperplasia in bone marrow; and extramedullary hematopoiesis in the spleen and liver. Flow cytometry confirmed the myeloproliferative phenotype. Genotypic and Western blot analysis demonstrated Cre-mediated excision and expression, ...
The t(5;12)(q33;p13) translocation associated with chronic myelomonocytic leukemia (CMML) generates a TEL/PDGFβR fusion gene. Here, we used a murine bone marrow transplant (BMT) assay to test the transforming properties of TEL/PDGFβR in vivo. TEL/PDGFβR, introduced into whole bone marrow by retroviral transduction, caused a rapidly fatal myeloproliferative disease that closely recapitulated human CMML. TEL/PDGFβR transplanted mice developed leukocytosis with Gr-1+ granulocytes, splenomegaly, evidence of extramedullary hematopoiesis, and bone marrow fibrosis, but no lymphoproliferative disease. We assayed mutant forms of the TEL/PDGFβR fusion protein - including 8 tyrosine to phenylalanine substitutions at phosphorylated PDGFβR sites to which various SH2 domain-containing signaling intermediates bind - for ability to transform hematopoietic cells. All of the phenylalanine (F-) mutants tested conferred IL-3-independence to a cultured murine hematopoietic cell line, but, in the BMT assay, ...
Taking into account the physiological relevance of the BM microenvironment, several investigators have tested the hypothesis if genetic alterations of niche cells are capable of inducing myeloid malignancies. This idea challenges the well-accepted concept that MDS and AML originate exclusively from HSPC-intrinsic genetic defects.. First evidence for niche-driven myeloid disorders came from a series of murine experiments with deletions of the Retinoblastoma gene, the retinoic acid receptor gamma (RAR-γ), IκBα or the Notch ligand endocytosis regulator Mib1 [16, 17, 18, 19]. In all experimental systems, mice developed a myeloproliferative disease phenotype characterized by leukocytosis, extramedullary hematopoiesis and splenomegaly. These studies highlighted that genetic changes of non-hematopoietic elements of the BM microenvironment can directly contribute to disease initiation. Still, in some of these experiments, simultaneous deletion of the candidate gene in hematopoietic and surrounding ...
Dendritic cells (DCs) regulate both immunity and tolerance. Here we have shown that the ubiquitin editing enzyme A20 (Tnfaip3) determines the activation threshold of DCs, via control of canonical NF-kappa B activation. Tnfaip3(fl)/(fl)Cd11c-cre(+) mice lacking A20 in DCs demonstrated spontaneous proliferation of conventional and double-negative T cells, their conversion to interferon-gamma (IFN-gamma)-producing effector cells, and expansion of plasma cells. They developed ds-DNA antibodies, nephritis, the antiphospholipid syndrome, and lymphosplenomegaly-features of systemic lupus erythematosus-and extramedullary hematopoiesis. A20-deficient DCs were resistant to apoptosis, caused by increased sensitivity to CD40L and RANKL prosurvival signals and upregulation of antiapoptotic proteins Bcl-2 and Bcl-x. They captured injected apoptotic cells more efficiently, resisted the inhibitory effects of apoptotic cells, and induced self-reactive effector lymphocytes. Because genetic polymorphisms in ...

The incidence of lung tumors was studied in hyperoxic and hypoxic pregnant A mice given injections intravenously of 25 mg. of urethan, and in their offspring. Among progeny born within 24 hours after their mothers received urethan, those born in an environment of approximately 100 per cent or 10 per cent O2 developed a significantly greater number of pulmonary tumors than did controls born in room air. The average number of tumors decreased significantly in all progeny from mothers given injections earlier than 24 hours prepartum. Myeloid leukemia and extramedullary hematopoiesis were also induced or potentiated by urethan. Mothers in all groups had more pulmonary tumors than their offspring had; 48-hour exposure resulted in an increased average number for mothers kept hyperoxic, as compared with those kept hypoxic or in room air. Mothers in all three groups developed a high incidence of mammary carcinomas.. ...

You cant see visceral fat. It hides around your liver and kidneys, intestines and reproductive system. Visceral fat clings to your organs. It can add 3 to 6 inches to your waist and hips even after you lose most of the pooch and muffin top.. The Internet, Facebook, and YouTube portray hundreds of exercise programs claiming to get rid of muffin tops. The beautiful and well-intentioned young men and women who present them (most of whom never had a muffin top) seem to have forgotten their high school human biology. Fat oxidation (fat burn) by the body is unrelated to the particular muscles being worked. Fat is taken from throughout the body and used through a complex process to provide energy. No matter how hard you do these exercises, you will not budge the muffin.. Heres the bottom line: You are exercising particular muscles. You are not exercising the fat that surrounds them. You are hardly affecting that fat at all. A solid hour of muffin top exercises in the gym uses less than half an ounce ...

Fer kinase, a protein involved in the regulation of cell-cell adhesion and proliferation, has been shown to be required during invertebrate development and has been implicated in leukemia, gastric cancer, and liver cancer. However, in vivo roles for Fer during vertebrate development have remained elusive. In this study, we bridge the gap between the invertebrate and vertebrate realms by showing that Fer kinase is required during zebrafish embryogenesis for normal hematopoiesis and vascular organization with distinct kinase dependent and independent functions. In situ hybridization, quantitative PCR and fluorescence activated cell sorting (FACS) analyses revealed an increase in both erythrocyte numbers and gene expression patterns as well as a decrease in the organization of vasculature endothelial cells. Furthermore, rescue experiments have shown that the regulation of hematopoietic proliferation is dependent on Fer kinase activity, while vascular organizing events only require Fer in a kinase

The day started off in a nice calm..NORMAL manner. Cat woke up first and came and crawled in bed with me. Ash woke up about 15 minutes later, observed that her Daddy was working today, and decided she was hungry. So I get out of bed and go to the kitchen to make some strawberry and blueberry muffins. Yum! 15 minutes in the oven and they are done. Called Alan, he came by to grab a few. The girls were settled at the kitchen table eating muffins, munching on the remainder of the KIX cereal they started while the muffins were cooking, and drinking their milk. They were content. Everything was as it should be. I quickly ate two muffins and drained the last of my own milk from my glass. Then I started thinking. I guess that was my first mistake.

So we resumed normal life, thinking of the ER visits as pit stops, and went about our business. That was until I visited a coffee shop by our house and got a muffin for Nico. We have eaten muffins and scones from this place for years. The teenaged kid recommended a power muffin, the white board at the drive-thru indicated a few of the ingredients that all sounded healthy and unappetizing but I got the muffin anyway. I handed it over to Nico and long story short, the power muffin was actually a peanut butter muffin. I have never heard of such a thing. Usually there are nuts sprinkled on top when a muffin has nuts in the mix, but there was no evidence of peanuts in this. When Nico started to vomit and cry (after less than a bite), I tore the muffin open looking for nuts. I was sure that I did not see nuts listed on the ingredients, but his reaction was too similar to the time he ate cashew butter. I had a bad cold by then, so I couldnt smell it. In less than an hour, and in spite of a large ...

Extramedullary hematopoiesis being an important feature of agnogenic myeloid metaplasia (AMM), a chronic myeloproliferative disease of clonal origin, may affect the kidneys, but this condition is usually asymptomatic. Until now, there is only one reported case of nephrotic syndrome associated with AMM. We present a patient with AMM who had nephrotic syndrome and whose renal biopsy revealed membranous glomerulonephritis together with renal extramedullary hematopoiesis. ...
In July 1985, a 43-year-old man was found to have polycythaemia vera. The peripheral blood counts were white cell count 14.15×109/l (neutrophils 80%, lymphocytes 14%, monocytes 5%, eosinophils 1%), haemoglobin concentration 24.8 g/dl, haematocrit 0.7, red cell count 8.15×1012/l (neither anisocytosis nor poikilocytosis nor tear-drop poikilocytosis were observed), platelets 234×109/l. As only the erythroid lineage was affected significantly, he was treated with isovolaemic phlebotomy until April 2004. In May 2004, the patient suddenly developed a spastic paraplegia. Nuclear magnetic resonance imaging showed a posterior extradural tumour extending from T3 to T11 … ...

The Ohio State University, Columbus, OH. The improved Cannon Drive corridor on the Medical Campus of The Ohio State University provides enhanced connectivity between the campus and the Olentangy River by creating a restored greenway along the river, while also providing a more efficient transportation route to improve traffic flow and accessibility through critical areas of the University campus. The EMH&T Visualization team played a key role within the larger EMH&T-led project team, assisting with the preliminary design and visualization of several roadway and river levee alignment options as well as preliminary grading. The quickness and increased level of accuracy allowed the design team to provide the best design possible that considers construction costs, safety, connectivity, construction sequencing and more. With the 3D model being designed to accurate grades and with actual road design criteria, the engineering design team was able to develop plans based on the model as a starting point ...

Excellent and durable response to radiotherapy in a rare case of spinal cord compression due to extra-medullary hematopoiesis in β-thalassemia intermedia: case report and clinicoradiological correlation
This is the first study to explore the efficacy of two different Reduced-intensity conditioning (RIC) regimens for allogeneic stem cell transplantation in myelofibrosis. The choice of 60 patients is based on feasibility reasons. GITMO data at hand points to an estimated accrual of twenty patients per year over a tree-year enrolment period. Criteria for defining sample size do not follow statistical power estimates in order to demonstrate the difference of lack of it between two treatments. However, the criteria reflect the overall efficacy and safety of comparing the two treatments among all patients requiring the treatment within the health system. This criterion offers the best estimate for power of study.. Myelofibrosis is a clonal hematopoietic stem cell disorder that is clinically characterized by progressive anemia, marked splenomegaly, extramedullary hematopoiesis, constitutional symptoms and a significant risk of evolution into acute leukaemia myelofibrosis can appear as a primitive or ...
Yetgin S, Yalçın SS. The effect of vitamin D3 on CD34 progenitor cells in vitamin D deficiency rickets. Turk J Pediatr 2004; 46: 164-166.. Vitamin D metabolites have multiple functions not only in calcium homeostasis, but also in hematopoiesis. To detect the effect of vitamin D on hematopoiesis with a surface glycoprotein marker, the proportions of the CD34+ cells were measured in bone marrow, peripheral blood and spleen prior to and after vitamin D3 treatment in an infant with severe rickets, myelofibrosis and myeloid metaplasia. CD34+ cells measured 0.4% in bone marrow, 8.0% in peripheral blood and 8.7% in splenic aspirate. The detection of a high and comparable level of CD34+ cells in both peripheral blood and splenic aspirate on admission and the decline in the level of CD34+ cells (2%) following treatment support that CD34+ cells were from extramedullary hematopoiesis in spleen. The improvement of rickets and hematological findings with treatment at the same time raises the possibility of ...

I used Sarahs silicone friand mold and some extra aluminium foil cupcakes mold for making these muffins. I kind of love the ingredients that make up this muffins....first , the use of shortening and icing sugar attracted me to want to try this out.

TY - JOUR. T1 - Sclerosing extramedullary hematopoietic tumor. T2 - emphasis on diagnosis by renal biopsy. AU - Sukov, William R.. AU - Remstein, Ellen D.. AU - Nascimento, Antonio G.. AU - Sethi, Sanjeev. AU - Lewin, Matthew. PY - 2009/4/1. Y1 - 2009/4/1. N2 - Sclerosing extramedullary hematopoietic tumor (SEMHT) is a rare lesion that typically arises in patients with chronic myeloproliferative disorders. Morphologically, it exhibits atypical megakaryocytes, granulocytic precursors, and erythroid precursors set in a background of dense collagen sclerosis. Sclerosing extramedullary hematopoietic tumor may be easily mistaken for other neoplasms, such as sarcoma, carcinoma, or Hodgkin lymphoma, particularly if pertinent clinical history is not provided. Misdiagnosis may occur because of the difficulty in recognizing the megakaryocytic lineage of the atypical cells and because of the paucity of other hematopoietic elements. We report a case of a 72-year-old man with proteinuria and renal ...

Results The most common sites for extramedullary disease at diagnosis were skin and soft tissue whereas liver involvement was the striking feature in extramedullary disease at disease relapse or progression. Regardless of therapy, extramedullary disease was associated with shorter progression-free and overall survival, as well as the presence of anemia, thrombocytopenia, elevated serum lactate dehydrogenase, cytogenetic abnormalities, and high-risk features in 70-and 80-gene risk models in univariate analysis. Multivariate analysis with logistic regression revealed that this disease feature was more prevalent in patients with an elevated centrosome index, as determined by gene expression profiling, as well as in myeloma molecular subtypes that are more prone to relapse. These include the MF subtype (also called the MAF subtype, associated with over-expression of the MAF gene seen with chromosome translocation 14;16 or 14;20) and the PR subtype (also called the Proliferation subtype, ...
