Derivative (5;19)(p10;q10) [der(5;19)(p10;q10)] is a rare chromosomal abnormality in myelodysplastic syndrome (MDS), and is genetically similar to deletion 5q [del(5q)]. However, MDS with der(5;19)(p10;q10) and 5q- syndrome are generally characterized as distinct subtypes. Here, we report a case of a patient with 5q- syndrome-like features as the first manifestation of MDS with der(5; 19)(p10;q10). A 59-year-old woman was admitted to our hospital for anemia without leukopenia and thrombocytopenia. She had received chemotherapy comprising carboplatin and docetaxel for endometrial cancer eight years before...

Anemia is common in older persons, and often remains unexplained despite a thorough clinical history, physical examination, and focused laboratory testing, including marrow aspiration, biopsy, and karyotyping. The advent of molecular genetic testing panels in hematology clinical practice has complicated the evaluation of older patients with unexplained anemia. While the presence of a somatic mutation provides evidence of clonal hematopoiesis and may support a diagnosis of a hematologic neoplasm such as one of the myelodysplastic syndromes (MDS), with rare exceptions, individual mutations are not strongly associated with one specific diagnosis, nor are they by themselves diagnostic of neoplasia...

BACKGROUND: Multiple studies have demonstrated that a significant amount of variability exists in various demineralized bone matrix (DBM) formulations, which casts doubts on its reliability in consistently promoting fusion. Bone marrow aspirate (BMA) is a cellular based graft that contains mesenchymal stem cells (MSCs) and growth factors can confer osteogenic and osteoinductive potential to DBM. The goal of this study was to describe the outcome of DBM enriched with concentrated BMA in patients undergoing combined lumbar interbody and posterolateral fusion...

The purpose of this article is to describe reconstruction of the maxillary alveolar ridge by use of a microvascular free flap combined with an immediate tissue-engineered bone graft. This novel surgical technique involved the use of a radial forearm free flap and immediate allogeneic avascular bone graft augmented with bone morphogenetic protein and bone marrow aspirate concentrate. A poly-d,l-lactic acid mesh was used a containment unit for the bone graft. The patient was successfully treated with a viable radial forearm free flap for soft tissue and regeneration of bone with adequate height and width, which allowed the placement of 3 dental implants with excellent arch coordination...

Leishmaniasis is a reticuloendothelial system disease that mostly observed before the age of 5. Visceral infection causes long-standing fever, weight loss, weakness, pancytopenia, and hepatosplenomegaly. Leishmania infantum is responsible for visceral leishmaniasis (VL) in Turkey. We present a case of hemophagocytic syndrome due to Leishmania infection diagnosed with an immunofluorescence antibody test (IFAT). Leishmania amastigotes were not observed on bone marrow aspiration. We consider that IFAT is very important for parasite detection in the diagnosis of VL in children, particularly when amastigotes are not obtained on bone marrow aspiration...

Background Articular cartilage lesions of the talus remain a challenging clinical problem because of the lack of natural regeneration and limited treatment options. Microfracture is often the first-line therapy, however lesions larger than 1.5 cm(2) have been shown to not do as well with this treatment method. Methods The objective of this retrospective study was to evaluate the outcomes of iliac crest bone marrow aspirate concentrate/collagen scaffold (ICBMA) and particulated juvenile articular cartilage (PJAC) for larger articular cartilage lesions of the talus...

Adult-onset Niemann-Pick disease type C (NPC) is an infrequent presentation of a rare neurovisceral lysosomal lipid storage disorder caused by autosomal recessive mutations in NPC1 (∼95%) or NPC2 (∼5%). Our patient was diagnosed at age 33 when he presented with a 10-yr history of difficulties in judgment, concentration, speech, and coordination. A history of transient neonatal jaundice and splenomegaly with bone marrow biopsy suggesting a lipid storage disorder pointed to NPC; biochemical ("variant" level cholesterol esterification) and ultrastructural studies in adulthood confirmed the diagnosis...

The haematological abnormalities associated with active pulmonary tuberculosis were known to human beings since decades but Immune Thrombocytopenic Purpura (ITP) secondary to pulmonary tuberculosis have been reported only in a couple of instances. We report a 27 year-old male patient who was admitted to our hospital with fever, shortness of breath, haematuria, epistaxis and generalized petechiae. The sputum positivity for Acid Fast Bacilli (AFB) and chest X-ray reports were suggestive of active pulmonary tuberculosis in our patient...

BACKGROUND: Bone marrow aspirate has been used in recent years to augment tendon-to-bone healing, including in rotator cuff repair. However, the healing mechanism in cell-based therapy has not been elucidated in detail. METHODS: Sixteen athymic nude rats were randomly allocated to 2 groups: experimental (human mesenchymal stem cells in fibrin glue carrier) and control (fibrin glue only). Animals were sacrificed at 2 and 4 weeks. Immunohistochemical staining was performed to evaluate Indian hedgehog (Ihh) signaling and SOX9 signaling in the healing enthesis...

There have been a small number of cases of scrub typhus-associated hemophagocytic syndrome (HPS), most of which were treated successfully using adequate antibiotics. Here, we report a case of Epstein-Barr virus (EBV)-associated HPS after scrub typhus infection that was not improved using antirickettsial treatment. A 73-year-old male who had been diagnosed with scrub typhus according to an eschar and a positive serology was transferred to our institution because of a persistent fever despite 7-day doxycycline therapy...

REVIEW
Joshua S Harford, Travis J Dekker, Samuel B Adams
Autologous bone marrow aspirate concentrate (BMAC) has become a popular orthobiologic to augment bone healing. The potential benefit comes from osteoprogenitor cells and growth factors that can lead to new bone formation in the setting of foot and ankle arthrodesis procedures. BMAC has an excellent safety record and has demonstrated efficacy in animal models of bone healing. Although scant, the literature on the use of BMAC in foot and ankle surgery does demonstrate promise for this orthobiologic adjuvant.

A 10-year-old castrated Domestic Short-Haired cat was presented to a primary care veterinarian for a wellness examination and laboratory examination for monitoring of diabetes mellitus. The CBC revealed marked thrombocytosis, leukopenia and macrocytic, normochromic anemia. The cat tested negative for FeLV and feline immunodeficiency virus, but was positive for Mycoplasma haemominutum by PCR. Hematologic abnormalities were not responsive to therapy, so a repeat CBC and a bone marrow aspiration for cytology were performed...

BACKGROUND: Cell therapy is an emerging potential biotherapy for critical limb ischaemia (CLI) patients who are not eligible for revascularization. However, the findings on this technique's efficacy are inconsistent. Trials investigating this topic focused on the more severe CLI patients who were often beyond any therapy. Therefore, identifying those who may truly benefit from cell transplantation is now warranted. To this end, we studied the prognostic value of tcPO2 for major amputation after 1 year in patients treated with bone marrow-derived cells...

Leishmaniasis is a "neglected tropical disease" and serious public health issue in Brazil. While dogs are recognized as particularly important reservoirs, recent reports of domestic cats infected with Leishmania sp. in urban areas suggest their participation in the epidemiological chain of the parasite in endemic areas. The aim of this study was to screen domestic cats for Leishmania sp. infection in an area where human and canine visceral leishmaniasis are endemic, followed by the identification of the species circulating in cats...

AIMS: The myelodysplastic syndromes (MDS) are a heterogeneous group of clonal haematopoietic stem cell disorders characterised by inefficient haematopoiesis and risk of progression to acute myeloid leukaemia. Metaphase cytogenetics is an extremely valuable clinical tool in the management of haematological malignancies. However, metaphase cytogenetics requires cellular proliferation, its sensitivity and resolution depends on the proportion of clonal cells in the sample and size of the lesion, respectively...

Plasma cell leukemia is very rare condition characterized by malignant proliferation of plasma cells in blood and bone marrow, which is aggressive and has a short survival even with conventional treatment. This ominous entity may be primary, or develops secondarily during the course of multiple myeloma. A 53-year-old Brazilian woman with multiple myeloma is described with bone marrow evaluation revealing 25% plasma cells. The quantification of plasma cell infiltration in bone marrow aspirate and immunohistochemistry study revealed consistent features of myeloma and plasma cell leukemia, and lambda light chain expression...
