    The aim of this study was to isolate stem cells from dental pulp of primary molars and incisors to be used as possible source for tissue engineering. Human primary molars and incisors were collected from subjects aged 4-7 year-old under standardized procedures. Within 24 hours, the tooth was cut at the cemento-enamel junction using hard tissue material cutter. The dental pulp tissue was extracted, digested and then cultured in Alpha Modified Eagles's Medium (α-MEM) supplemented with 20% FCS, 100 mM L-ascorbic acid 2-phosphate, 200 mM L-glutamine and 5000 units/ml Penicillin/Streptomycin. The cells were observed daily under the microscope until confluence. Children's tooth pulp- derived progenitor cells were found positive for stem cell markers CD105 and CD166, which are consistent with the finding for mesenchymal stem cells (MSCs) from bone marrow.

    Objective: Mesenchymal stem cells (MSC) are multipotent, non-haematopoietic stem cells that are
    capable of differentiating into different varieties of mature cell types such as osteoblasts, chondrocytes, adipocytes, and myoblasts. There is abundant evidence showing that MSC not only affect the differentiation of haematopoietic progenitors, but also the function of mature cells like lymphocytes and neutrophils. However the effect of MSC on neutrophil function and its responses is not well studied. Therefore, this study was conducted to assess the effect of MSC on neutrophil nitric oxide production. Method: Neutrophils from heparanised venous blood were isolated using Ficoll-Hypaque density gradient centrifugation followed by Dextran sedimentation and red blood cell (RBC) lysis. Isolated neutrophils were on average of 97% purity as determined by morphologic analysis. MSC were generated from human bone marrow and characterised by immunophenotyping (monoclonal antibodies CD105, CD73 and CD34) using a flowcytometer. In order to test the effects of MSC on neutrophil function, isolated neutrophils were co-cultured in the presence or absence of MSC at different ratios for 24 and 48 hours. The amount of nitric oxide released was used as an indication of oxidative burst and measured using the Griess assay. Result: The results indicate that MSC neither elevate the NO level when cocultured with resting neutrophils nor alone. However MSC profoundly inhibit the secretion of nitric oxide in PMA stimulated neutrophils after 24hr of incubation. Conclusion: MSC exert an immunomodulatory effect on neutrophil by suppressing neutrophil oxidative burst in vitro.

    The thalassaemias are the commonest single gene disorders amongst the inherited diseases. In Malaysia, there are an estimated 2200 transfusion dependent thalassaemia patients. With a carrier rate of 3-5%, 120-340 new cases of thalassaemia are expected to be born each year. The reference treatments for these patients are regular blood transfusions and iron chelation therapy. With optimal management, these patients are able to survive into the third or fourth decade of life and most importantly avoid the complications related to transfusions and iron overload. The use of desferal locally is still limited to only those who can afford i.e. about 30% of the cases. Treatment for some of the complications such as hepatitis C, diabetes mellitus, growth impairment and pubertal delay, are now available. Curative treatment approaches like bone marrow transplantation have now become standard treatment for eligible cases whilst cord blood transplantation may yet offer hope for those who are without compatible sibling donors. Research on globin gene therapy looks very promising but will probably take some time to deliver. Hb F switching is a very novel idea but so far the results are mainly anecdotal. Finally, the strive for optimal management of thalassaemia must come hand in hand with a prevention programme to achieve a reduction of new cases.

  4. Fulltext A Rare Cause of Acute Kidney Injury: Primary Renal Lymphoma in a Patient with Human Immunodeficiency Virus
    Mustafar R, Kamaruzaman L, Chien BH, Yahaya A, Mohd Nasir N, Mohd R, et al.
    Case Rep Med, 2018;2018:8425985.
    PMID: 30186328 DOI: 10.1155/2018/8425985
    We reported a case of primary renal lymphoma (PRL) presented with non-oliguric acute kidney injury and bilateral kidney infiltrates in an individual with human immunodeficiency virus (HIV) disease. Acute kidney injury secondary to lymphoma infiltrates is very rare (less than 1% of hematological malignancy). A 37-year-old gentleman with underlying human immunodeficiency virus (HIV) disease was on combined antiretroviral therapy since diagnosis. He presented to our center with uremic symptoms and gross hematuria. Clinically, bilateral kidneys massively enlarged and were ballotable. Blood investigations showed hemoglobin of 3.7 g/L, urea of 65.6 mmol/L, and serum creatinine of 1630 µmol/L with hyperkalemia and metabolic acidosis. An urgent hemodialysis was initiated, and he was dependent on regular hemodialysis subsequently. Computed tomography renal scan showed diffuse nonenhancing hypodense lesion in both renal parenchyma. Diagnosis of diffuse large B cell lymphoma with germinal center type, CD20 positive, and proliferative index 95% was confirmed via renal biopsy, and there was no bone marrow infiltrates. Unfortunately, the patient succumbs prior to initiation of chemotherapy.

    PMID: 30483553 DOI: 10.1002/jgh3.12027
    Mesenchymal stem cell (MSC) transplant may offer an alternative to liver transplantation in patients with end-stage liver disease. However, its efficacy remains uncertain. MSC was performed on a 50-year-old male with decompensated (Child-Turcotte-Pugh grade C) alcoholic liver cirrhosis due to an absence of donors for adult-deceased and living-related liver transplantation. Autologous bone marrow-derived MSCs were harvested from the patient and cultured using standard protocols. The MSCs were subsequently re-administrated into the liver via hepatic intra-arterial infusion on two separate occasions. After infusion, there was an improvement in biochemical parameters (serum total bilirubin, serum albumin), and a reduction of diuretic use for ascites for up to 8 weeks. However, all biochemical and clinical parameters deteriorated on long-term follow-up without any further infusions. The patient eventually succumbed to his disease. MSC transplantation may have a clinical benefit on adult patients with end-stage liver cirrhosis, but this appears to be transitory.

  6. Fulltext Leukemic phase of ALK-negative anaplastic large cell lymphoma in a patient who is on androgenic steroids: A case report
    Kasinathan G
    Ann Med Surg (Lond), 2020 Jan;49:1-4.
    PMID: 31871676 DOI: 10.1016/j.amsu.2019.11.007
    ALK-negative anaplastic large cell lymphoma (ALCL) is a peripheral T-cell lymphoma that usually involves lymph nodes or extranodal sites. Leukemic phase of ALK-negative ALCL is exceedingly rare and often carries a poor prognosis. Androgenic steroids have gained popularity among the young, and at higher doses, it can result in immune dysregulation and may be potentially carcinogenic. Case presentation: A 30-year-old gentleman of Malay ethnicity presented to the hematology department with night fevers, loss of weight and bony pain for the past 6 weeks. He is a gymnasium instructor with a history of chronic usage of intramuscular testosterone enanthate. Physical examination revealed ecchymosis over the left elbow and hepatomegaly. A complete blood count depicted anemia, thrombocytopenia and leucocytosis. An 18-Fluorodeoxyglucose positron emission tomography (18-FDG PET/CT) imaging showed a hypermetabolic anterior mediastinal mass of 6.8 × 7.0 × 6.5 cm with diffuse hypermetabolism in the liver, spleen and axial skeleton. The bone marrow trephine and mediastinal tissue histology were consistent with leukemic ALK-negative ALCL. He was treated with CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, prednisolone) induction chemotherapy in which he required intensive antibiotic and blood support. He progressed with worsening B symptoms and new diffuse lymphadenopathies suggesting rapid dissemination of the disease. He subsequently succumbed to multiorgan failure with disseminated intravascular coagulopathy at the intensive care unit. Conclusion: Leukemic phase ALK-negative ALCL often carries a complex karyotype and requires early intensive polychemotherapy. Use of anabolic steroids depletes the ability of defending lymphocytes to remove tumour producing cells.

    Samuel S, Ahmad RE, Ramasamy TS, Manan F, Kamarul T
    Injury, 2018 Apr;49(4):775-783.
    PMID: 29503013 DOI: 10.1016/j.injury.2018.02.020
    BACKGROUND: It has been previously suggested that the use of regenerative promoters, which include bone marrow-derived mesenchymal stem cells (MSCs) or natural growth factors supplement such as platelet-rich concentrate (PRC) could promote cartilage regeneration. However, the notion that the concurrent use of both promoters may provide a synergistic effect that improves the repair outcome of focal cartilage injury has not been previously demonstrated. This study was thus conducted to determine whether the concomitant use of PRC could further enhance the reparative potential of MSCs encapsulated in alginate transplanted into focal cartilage injury in rabbits.

    METHODS: Artifically created full thickness cartilage defects were made on the weight-bearing region of medial femoral condyles in bilateral knees of New Zealand White rabbits (N = 30). After one month, the right knee was treated with either i) PRC (n = 10), ii) MSCs (n = 10), or, iii) a combination of PRC and MSCs (PRC + MSC) (n = 10), all encapsulated in alginate. The left knee remained untreated (control). Rabbits were sacrificed at 3 and 6 months after treatment. Cartilage tissue regeneration was accessed using ICRS morphologic scoring, histologic grading by O'Driscoll scoring, immunohistochemical staining and quantitative analysis of glycosaminoglycans (GAG) per total protein content.

    RESULTS: At 3 months, transplantation using PRC alone was equally effective as MSCs in inducing the repair of cartilage defects. However, PRC + MSC resulted in significantly higher ICRS and O'Driscoll scores (p

    Cytomegalovirus (CMV) retinitis occurs predominantly in Human Immunodeficiency Virus (HIV) -infected patients. It was also reported in HIV-seronegative patients with systemic autoimmune disorder requiring systemic immunosuppression, organ or bone marrow transplantation, haematological or breast malignancy receiving chemotherapy, ocular diseases following intraocular or periocular corticosteroid injection, diabetes mellitus and Good syndrome. However, CMV retinitis in patients with concurrent dermatomyositis and malignancy has not been previously reported. It has not been reported in cancer other than haematological or breast malignancy, or in cancer patient prior to chemotherapy. We report a case of 40-year-old HIV-seronegative woman with underlying dermatomyositis and lung malignancy who developed right CMV retinitis which relapsed after recommencement of immunosuppressant. Both episodes of CMV retinitis were successfully treated after taken her immunocompromised state into consideration.

    PMID: 31750119 DOI: 10.1007/s12070-015-0930-8
    Myeloid sarcoma is a rare malignant extramedullary neoplasm of myeloid precursor cells. This disorder may occur in concomitance with or precede development of acute or chronic myeloid leukemia. Sometimes, it is the initial manifestation of relapse in a previously treated acute myeloid leukemia. We report a case of 11 years old boy with acute myeloid leukemia in remission state, presented with short history of right otalgia associated with facial nerve palsy. Diagnosis of right acute mastoiditis with facial nerve palsy as complication of acute otitis media was made initially. Patient underwent simple cortical mastoidectomy but histopathology from soft tissue that was sent revealed diagnosis of myeloid sarcoma. A leukemic relapse was confirmed by paediatric oncologist through bone marrow biopsy. Chemotherapy was commenced but patient responded poorly to the treatment.

    Acute myeloid leukaemia (AML) is one of the fatal haematological malignancies as a consequence of its genetic heterogeneity. At present, the prediction of the clinical response to treatment for AML is based not only on detection of cytogenetic aberrations but also by analysing certain molecular genetic alterations. There are limited in sights into the contribution, disease progression, treatment outcome, and characterisation with respect to the uncommon chromosomal abnormalities leading to AML. Here, we describe the clinical, morphological, cytogenetic, and mutational findings of a 52-year-old female patient with AML without maturation (AML-M1). Conventional karyotyping and spectral karyotyping (SKY) were done on metaphase chromosomes from bone marrow cells at the time of diagnosis. A mutation analysis was performed on the hotspot regions of various genes, including FLT3, CEBPA, NPM1, RAS, c-KIT, IDH1 and IDH2. Cytogenetic and mutation analyses revealed a novel translocation, t(X;2)(q28;p22), with both NPM1 and IDH1 mutations. To the best of our knowledge, the presence of both NPM1 and IDH1 mutations in t(X;2)(q28;p22) is a novel finding in AML.

    A 69-year-old female complained of intermittent left hip pain for the past 3 years. Biochemical tests revealed normal serum calcium and phosphorus with markedly raised alkaline phosphatase. MRI of the hip revealed extensive marrow signal abnormalities at the left pelvic bone, while CT of the thorax revealed a spiculated lung nodule at the left lower lung lobe. In order to diagnose either primary, metastatic bone tumour or Paget's disease of the bone (PDB), an open biopsy of the left iliac bone was performed. The histopathology of bone biopsy of the left iliac bone was consistent with PDB. A CT guided biopsy of the lung mass done later revealed adenocarcinoma of the lung. She had 18F-FDG PETCECT Scan for staging evaluation and result was suggestive of new bony metastases. Patient was started on IV Zoledronic acid for treatment of the PDB. In view of the stage 4 lung adenocarcinoma with bony metastases, patient was scheduled for palliative chemotherapy.

    PMID: 16329531
    Rearrangement of the immunoglobulin heavy chain (IgH) gene has been used as a marker of lineage and clonality in the diagnosis of B lymphoproliferative disorders. A number of PCR-based techniques have been developed to overcome the disadvantages of Southern blotting, the standard technique in detecting IgH gene rearrangement. Using an established seminested PCR technique with consensus primers to the V and J regions of the IgH gene, we analysed DNA prepared from peripheral blood and/or bone marrow specimens from 30 cases of known B cell malignancies (16 chronic lymphocytic leukemia, 11 acute lymphoblastic leukemia and 3 Non-Hodgkin Lymphoma), 3 cases of T lymphoproliferative disease and 3 cases of reactive lymphocytosis diagnosed in Hospital UKM to detect rearranged IgH gene. We found that monoclonality as represented by the presence of rearranged IgH gene were demonstrated in all the 30 cases. The PCR findings showed 100% concordance with the Southern blot analysis results which also showed rearranged IgH bands in all the 30 cases. We also found that none of the cases of T lymphoproliferative diseases and reactive lymphocytosis showed presence of rearranged IgH band, suggesting that the amplification using the IgH primers is lineage-specific. In conclusion, we find the PCR a useful method to detect IgH gene rearrangement in peripheral blood and bone marrow specimen. Since the PCR results are comparable to that of the Southern blotting in demonstrating B cell monoclonality and owing to its many advantages we feel that it can replace the Southern blot technique for the diagnosis of B cell malignancies.

  15. Fulltext Identification of Pathways Mediating Growth Differentiation Factor5-Induced Tenogenic Differentiation in Human Bone Marrow Stromal Cells
    Tan SL, Ahmad TS, Ng WM, Azlina AA, Azhar MM, Selvaratnam L, et al.
    PLoS One, 2015;10(11):e0140869.
    PMID: 26528540 DOI: 10.1371/journal.pone.0140869
    To date, the molecular signalling mechanisms which regulate growth factors-induced MSCs tenogenic differentiation remain largely unknown. Therefore, a study to determine the global gene expression profile of tenogenic differentiation in human bone marrow stromal cells (hMSCs) using growth differentiation factor 5 (GDF5) was conducted. Microarray analyses were conducted on hMSCs cultures supplemented with 100 ng/ml of GDF5 and compared to undifferentiated hMSCs and adult tenocytes. Results of QuantiGene® Plex assay support the use and interpretation of the inferred gene expression profiles and pathways information. From the 27,216 genes assessed, 873 genes (3.21% of the overall human transcriptome) were significantly altered during the tenogenic differentiation process (corrected p<0.05). The genes identified as potentially associated with tenogenic differentiation were ARHGAP29, CCL2, integrin alpha 8 and neurofilament medium polypeptides. These genes, were mainly associated with cytoskeleton reorganization (stress fibers formation) signaling. Pathway analysis demonstrated the potential molecular pathways involved in tenogenic differentiation were: cytoskeleton reorganization related i.e. keratin filament signaling and activin A signaling; cell adhesion related i.e. chemokine and adhesion signaling; and extracellular matrix related i.e. arachidonic acid production signaling. Further investigation using atomic force microscopy and confocal laser scanning microscopy demonstrated apparent cytoskeleton reorganization in GDF5-induced hMSCs suggesting that cytoskeleton reorganization signaling is an important event involved in tenogenic differentiation. Besides, a reduced nucleostemin expression observed suggested a lower cell proliferation rate in hMSCs undergoing tenogenic differentiation. Understanding and elucidating the tenogenic differentiation signalling pathways are important for future optimization of tenogenic hMSCs for functional tendon cell-based therapy and tissue engineering.

  17. Fulltext Pharmacologically antagonizing the CXCR4-CXCL12 chemokine pathway with AMD3100 inhibits sunlight-induced skin cancer
    Sarchio SNE, Scolyer RA, Beaugie C, McDonald D, Marsh-Wakefield F, Halliday GM, et al.
    J Invest Dermatol, 2014 Apr;134(4):1091-1100.
    PMID: 24226205 DOI: 10.1038/jid.2013.424
    One way sunlight causes skin cancer is by suppressing anti-tumor immunity. A major mechanism involves altering mast cell migration via the C-X-C motif chemokine receptor 4-C-X-C motif chemokine ligand 12 (CXCR4-CXCL12) chemokine pathway. We have discovered that pharmacologically blocking this pathway with the CXCR4 antagonist AMD3100 prevents both UV radiation-induced immune suppression and skin cancer. The majority of control mice receiving UV-only developed histopathologically confirmed squamous cell carcinomas. In contrast, skin tumor incidence and burden was significantly lower in AMD3100-treated mice. Perhaps most striking was that AMD3100 completely prevented the outgrowth of latent tumors that occurred once UV irradiation ceased. AMD3100 protection from UV immunosuppression and skin cancer was associated with reduced mast cell infiltration into the skin, draining lymph nodes, and the tumor itself. Thus a major target of CXCR4 antagonism was the mast cell. Our results indicate that interfering with UV-induced CXCL12 by antagonizing CXCR4 significantly inhibits skin tumor development by blocking UV-induced effects on mast cells. Hence, the CXCR4-CXCL12 chemokine pathway is a novel therapeutic target in the prevention of UV-induced skin cancer.

  18. Nucleotide sequence and phylogenetic analysis of Newcastle disease virus isolates from recent outbreaks in Taiwan
    Yang CY, Chang PC, Hwang JM, Shieh HK
    Avian Dis, 1997 Apr-Jun;41(2):365-73.
    PMID: 9201401
    Portions of the hemagglutinin neuraminidase (HN) gene of Newcastle disease virus (NDV) isolates from two recent outbreaks were sequenced to investigate epidemiology of this disease in Taiwan. These NDV isolates were all viscerotropic velogenic according to the clinical lesions produced in chickens. Sequence data were obtained from 14 NDV isolates (12 from 1995 and 2 from 1984). All isolates differed in their nucleotide sequences (from 0.3 to 15.3%), and represented potentially different strains of NDV. Phylogenetic analysis revealed that these isolates are closely related to viruses isolated from Japan and Malaysia. Some viruses isolated in 1995 appeared to evolve from viruses isolated in 1984. The results suggest that the 1995 outbreak of Newcastle disease (ND) in Taiwan may have been caused by multiple strains of velogenic NDV that have cocirculated in Taiwan for some time. Moreover, NDV isolates from racing pigeons were very similar to isolates from chickens in the same period, suggesting that both domestic and free-living birds were involved in the spread of ND in Taiwan.

    PMID: 32169986 DOI: 10.1136/bcr-2019-233330
    An 18-year-old male adolescent presented with prolonged high spiking temperature, photosensitive rash, oral ulcers and reduced hearing bilaterally of recent onset. Examination revealed malar rash, vasculitis rash over bilateral palms and soles, oral and buccal ulcers, palpable posterior auricular and inguinal lymph nodes, and reduced hearing bilaterally. His further investigations noted pancytopaenia, elevated transaminases, hyperferritinaemia, low C3 and C4 levels, positive antinuclear antibody, double-stranded DNA and direct Coombs test, while bone marrow aspiration revealed active phagocytic activity suggestive of hemophagocytic syndrome. We made a diagnosis of systemic lupus erythematosus with macrophage activation syndrome. We treated him with pulse intravenous methylprednisolone and his condition improved drastically. Temperature resolved on the next day after intravenous methylprednisolone; bilateral sensorineural hearing loss improved to near-normal hearing after treatment. He remained well during follow-up with a tapering dose of prednisolone.
