Myelodysplastic syndrome (MDS) is cytogenetically heterogeneous and retains variable risk for acute myeloid leukemia transformation. Though not yet fully understood, there is an association between genetic abnormalities and defects in gene expression. The functional role for infrequent cytogenetic alteration remains unclear. An uncommon chromosomic abnormality is the presence of the Philadelphia (Ph) chromosome. Here, we report a patient with Ph+ MDS treated with low dose Dasatinib who achieved hematologic response for 7 months...

BACKGROUND: Large vessel vasculitis is a rare disorder usually occurring in the context of the autoimmune conditions of giant cell arteritis and Takayasu's arteritis. Case reports have described large vessel vasculitis occurring in individuals with myelodysplastic syndrome, preceding transformation to acute myeloid leukemia. CASE PRESENTATION: A 56-year-old Afghanistan-born woman presented with fever, a tender left carotid artery, and raised inflammatory markers...

Following advances in critical care, in-hospital multiple organ failure-related mortality is declining. Consequently, incidence of chronic critical illness is increasing. These patients linger in the intensive care unit, have high resource utilization, and poor long-term outcomes. Within this population, the authors propose that a substantial subset of patients have a new phenotype: persistent inflammation, immunosuppression, and catabolism syndrome. There is evidence that myelodysplasia with expansion of myeloid-derived suppressor cells, innate and adaptive immune suppression, and protein catabolism with malnutrition are major contributors...

PURPOSE: To evaluate perioperative management for the prevention of postoperative shunt infection and malfunction after intraperitoneal urological surgery in patients with myelodysplasia and a ventriculoperitoneal shunt. METHODS: From 2005 to 2015, 20 consecutive patients with myelodysplasia and a ventriculoperitoneal shunt who underwent intraperitoneal urological surgeries were managed with the same perioperative regimen. Intraperitoneal surgeries involved opening gastrointestinal tracts, including bladder augmentation by enterocystoplasty, creating continent catheterizable channels and Malone antegrade continent enema...

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

INTRODUCTION: GATA2 mutations are associated with several conditions, including Emberger syndrome which is the association of primary lymphedema with hematological anomalies and an increased risk for myelodysplasia and leukemia. OBJECTIVE: To describe a family with Emberger syndrome with incomplete penetrance. METHODS: A DNA sequencing of GATA2 gene was performed in the parents and offspring (five individuals in total). RESULTS: The family consisted of 5 individuals with a GATA2 null mutation (c...

BACKGROUND: The enormous potential of complex data files generated by 10-color flow cytometry (FC) is hindered by the requirement for exhaustive manual gating and the complexity of multidimensional data visualization. We propose a model using radar plots (RPs), to improve FC data visualization by capturing multidimensionality and integration of FC findings. METHOD: We analysed 12 normal/reactive bone marrow (N/R BM) samples and 12 BM samples from patients with myelodysplasia (MDS) with 10-color FC...

Myelodysplastic syndromes are typically diseases of older adults. Early onset patients may have distinct molecular and clinical features or reflect a demographic continuum. The identification of differences between early onset patients and those diagnosed at a traditional age has the potential to advance understanding of the pathogenesis of myelodysplasia and may lead to formation of distinct morphologic subcategories. We studied a cohort of 634 patients with various subcategories of myelodysplastic syndrome and secondary acute myeloid leukemia, stratifying based on age at presentation and clinical parameters...

Genetic alterations, including mutations and copy number alterations, are central to the pathogenesis of myelodysplastic syndromes and related diseases (myelodysplasia), but their roles in allogeneic stem-cell transplantation have not fully been studied in a large cohort of patients. We enrolled 797 patients who had been diagnosed with myelodysplasia at initial presentation and received transplantation via the Japan Marrow Donor Program. Targeted-capture sequencing was performed to identify mutations in 69 genes, together with copy number alterations, whose effects on transplantation outcomes were investigated...

Patients who undergo autologous hematopoietic stem cell transplantation (aHCT) for treatment of a relapsed or refractory lymphoma are at risk of developing therapy related- myelodysplasia/acute myeloid leukemia (t-MDS/AML). Part of the risk likely resides in inherent interindividual differences in their DNA repair capacity (DRC), which is thought to influence the effect chemotherapeutic treatments have on the patient's stem cells prior to aHCT. Measuring DRC involves identifying small differences in repair proficiency among individuals...

BACKGROUND: Effects of aging on hematologic and biochemical variables are well described in people. Anemia of the elderly is attributed to iron deficiency, anemia of chronic disease, chronic kidney disease, myelodysplasia, or idiopathic causes. Limited studies have examined these variables in aging dogs, but they have typically examined single breeds in research settings. OBJECTIVE: The objective of this study was to identify differences in CBC and biochemistry values between adult and aged dogs of many breeds...

INTRODUCTION AND HYPOTHESIS: To evaluate the effects of sacral neuromodulation (SNM) on pregnancy and the impact of delivery on SNM function. METHODS: A systematic search was conducted through January 2016. We selected studies including women who had SNM and a subsequent pregnancy. RESULTS: Out of 2,316, eight studies were included, comprising 22 patients (26 pregnancies). SNM indications were Fowler's syndrome in 11, urinary retention in 6, fecal incontinence in 1, fecal and urinary urgency in 1, overactive bladder in 1, intractable interstitial cystitis in 1, and myelodysplasia in 1...

OBJECTIVES: To analyze clinical and electromyographic treatment outcome of dysfunctional voiding (DV) with animated Biofeedback (Bfb). Clinical or electromyographic variables associated with higher success rate were checked. PATIENTS AND METHODS: Cross-sectional study of patients with DV, that in 2010- 2015 followed animated Bfb program. Efficacy was measured with Uroflowmetry, Electromyography (EMG) and validated clinical questionnaire. Inclusion criteria: no myelodysplasia, no anatomical malformations and a minumin of 3 Bfb sessions...

BACKGROUND: Two chromosome anomalies are frequent in the bone marrow (BM) of patients with Shwachman-Diamond syndrome (SDS): an isochromosome of the long arm of chromosome 7, i(7)(q10), and an interstitial deletion of the long arm of chromosome 20, del(20)(q). These anomalies are associated with a lower risk of developing myelodysplasia (MDS) and/or acute myeloid leukemia. The chromosome anomalies may be due to an SDS-specific karyotype instability, reflected also by anomalies that are not clonal, but found in single cells in the BM or in peripheral blood (PB)...

AIMS: The aim of this study was to determine the value of urine nerve growth factor (NGF), transforming growth factor beta 1 (TGF-Beta-1), tissue inhibitor of matrix metalloproteinase 2 (TIMP-2) levels to predict the urodynamic profile before and after botulinum neurotoxin type A (BoNT-A) treatment in children with myelodysplasia. METHODS: This prospective study included 15 children with myelodysplasia who underwent intradetrusor BoNT-A injections due to neurogenic detrusor overactivity (NDOA)...
