    A 21-year-old lady diagnosed with Stage 3 ovarian yolk sac tumor (YST) underwent primary cytoreductive fertility sparing surgery, followed by conventional courses of platinum-based chemotherapy and etoposide. Recurrence at cul-da-sac was noted after a short period of remission and secondary debulking performed followed by four cycles of conventional chemotherapy. The patient's disease progressed despite courses of treatments. A joint team management including a hematologist was commenced following the failure of conventional chemotherapies. Two cycles of high-dose chemotherapy (HDCT) with ifosfamide/cisplatin/etoposide (ICE) regimen, followed by autologous stem cell transplantation (ASCT) were given. With this salvage treatment, she remained in complete remission and disease-free for more than 30 months, while maintaining her reproductive function. These approaches appear to be effective as a salvage treatment in selected cases of patients with ovarian germ cell tumor, especially those who failed primary conventional chemotherapy.

    This study was to determine if autologous bone marrow mesenchymal stem cells (BMSCs) cultured in chondrogenic medium could repair surgically induced osteoarthritis. Sheep BMSCs were cultured in medium containing 5ng/ml TGFbeta3 + 50ng/ml IGF-1 for three weeks. The cultured cells were then suspended at density of 2x10(6) cell/ml and injected intraarticularly into the osteoarthritic knee joint. After six weeks, the distal head of the femur and the proximal tibial plateau were removed and stained with H&E. The results indicated that knee joints treated with autologous BMSCs cultured in chondrogenic medium showed clear evidence of articular cartilage regeneration in comparison with other groups.

    AIM: To retrospectively report the clinical outcomes of non-Hodgkin's Lymphoma (NHL) patients post high dose therapy (HDT) with autologous haematopoietic stem cell transplant (AHSCT) and determine whether upfront transplant, which is a first-line consolidative treatment with induction chemotherapy, would be a feasible modality in a resource-limited country.

    METHODS: The medical records for NHL patients who had undergone HDT followed by AHSCT from October 1997 to November 2016 from two hospitals in Klang Valley, Malaysia were obtained from the medical record database and analysed retrospectively through statistical analysis.

    RESULTS: A total of 148 patients were retrospectively identified post-AHSCT, where the majority of whom had B cell lymphoma (53.4%). Majority of patients (88.5%) were in complete remission before AHSCT. The overall survival (OS) and event-free survival (EFS) at 3 years were 68.9% and 60.8%, respectively. The major cause of death was disease progression at 73.9%, while transplant-related mortality was 15.2%, with a median follow-up period of 179.5 weeks.

    CONCLUSION: Our study illustrates the promising outcomes of HDT with AHSCT in NHL patients in a resource-limited country. We recommend larger studies to be conducted in the future with a longer duration of follow-up to validate our findings.

    Importance: Herpes zoster, a frequent complication following autologous hematopoietic stem cell transplantation (HSCT), is associated with significant morbidity. A nonlive adjuvanted recombinant zoster vaccine has been developed to prevent posttransplantation zoster.

    Objective: To assess the efficacy and adverse event profile of the recombinant zoster vaccine in immunocompromised autologous HSCT recipients.

    Design, Setting, and Participants: Phase 3, randomized, observer-blinded study conducted in 167 centers in 28 countries between July 13, 2012, and February 1, 2017, among 1846 patients aged 18 years or older who had undergone recent autologous HSCT.

    Interventions: Participants were randomized to receive 2 doses of either recombinant zoster vaccine (n = 922) or placebo (n = 924) administered into the deltoid muscle; the first dose was given 50 to 70 days after transplantation and the second dose 1 to 2 months thereafter.

    Main Outcomes and Measures: The primary end point was occurrence of confirmed herpes zoster cases.

    Results: Among 1846 autologous HSCT recipients (mean age, 55 years; 688 [37%] women) who received 1 vaccine or placebo dose, 1735 (94%) received a second dose and 1366 (74%) completed the study. During the 21-month median follow-up, at least 1 herpes zoster episode was confirmed in 49 vaccine and 135 placebo recipients (incidence, 30 and 94 per 1000 person-years, respectively), an incidence rate ratio (IRR) of 0.32 (95% CI, 0.22-0.44; P

    Although survival rates for childhood cancers have improved steadily over the past two decades, the outcome for advanced stage solid tumours remains poor. Many of these tumours are chemosensitive but most chemotherapeutic regimens are limited by their haematological toxicities. Much attention is now focused on mega-dose chemotherapy followed by stem cell rescue in the treatment of disseminated neuroblastoma, rhabdomyosarcoma, germ cell tumour and brain tumours. There is a preferential shift towards peripheral blood stem cell transplantation instead of bone marrow transplantation because of its advantages of faster engraftment, decreased transfusion and antibiotic usage and shortened hospitalisation. This mode of therapy is dependent on technologies including peripheral blood stem cell harvesting, cell cryopreservation and thawing. These technologies were recently made available in Malaysia and we report our early experience.

    BACKGROUND: Multiple myeloma is the third most common hematologic malignancy in Malaysia. The introduction of novel agents over the past decades has improved patient outcome and survival substantially. However, these agents incur significant economic burden, thus leading to limited use in less developed countries. This study aims to report on the real-world treatment pattern and outcome of newly diagnosed multiple myeloma (NDMM) patients from a resource-constraint setting.

    METHODS: This is a retrospective study on NDMM patients diagnosed between 1 January 2008 and 31 December 2022 in a single academic center. Patients' demographic and treatment details were included for analysis of progression free survival (PFS) and overall survival (OS).

    RESULTS: One hundred and thirty-six NDMM patients with a median age of 64.0 years (ranged from 38 to 87 years old) were included. Bortezomib-containing regimens were the most commonly used induction agent, followed by thalidomide. Almost half of the patients (47.1%) achieved very good partial response (VGPR) or complete remission (CR), while 31.6% achieved partial response (PR). Bortezomib containing regimen was associated with significantly deeper and more rapid response, (p=0.001 and p=0.017, respectively) when compared to other agents. Only 22.8% of these patients proceeded to upfront autologous haematopoietic stem cell transplantation.  The median OS and PFS were 60.0 months and 25.0 months, respectively. Best initial response and upfront autologous stem cell transplantation (ASCT) were significantly associated with better PFS.

    CONCLUSION: Achieving at least a VGPR significantly associated with better outcome in NDMM patients. In a resource constrain country, we recommend incorporating bortezomib in the induction therapy followed with an upfront ASCT.

    BACKGROUND AIMS: Mesenchymal stromal cells (MSC) may improve cardiac function following myocardial infarction. MSC can differentiate into cardiomyocytes and endothelial cells while exerting additional paracrine effects. There is limited information regarding the efficacy of route for MSC treatment of severe dilated cardiomyopathy (DCM). The aim of this study was to demonstrate the clinical safety, feasibility and efficacy of direct intramyocardial and intracoronary administration of autologous bone marrow-derived MSC treatment for no-option patients with chronic severe refractory DCM.

    METHODS: Ten symptomatic patients with DCM and refractory cardiac function, despite maximum medical therapy, were selected. Five had ischemic DCM deemed unlikely to benefit from revascularization alone and underwent bypass operations with concurrent intramyocardial MSC injection (group A). Two patients had previous revascularization and three had non-ischemic DCM and received intracoronary MSC injection (group B).

    RESULTS: Group A and B patients received 0.5-1.0 × 10(6) and 2.0-3.0 × 10(6) MSC/kg body weight, respectively. All patients remained alive at 1 year. There were significant improvements from baseline to 6 and 12 months in left ventricular ejection fraction and other left ventricular parameters. Scar reduction was noted in six patients by 12 months.

    CONCLUSIONS: Autologous bone marrow MSC treatment is safe and feasible for treating chronic severe refractory DCM effectively, via intracoronary or direct intramyocardial administration at prescribed doses.

    Chondrogenic differentiated mesenchymal stem cells (CMSCs) have been shown to produce superior chondrogenic expression markers in vitro. However, the use of these cells in vivo has not been fully explored. In this study, in vivo assessment of cartilage repair potential between allogenic-derived chondrogenic pre-differentiated mesenchymal stem cells and undifferentiated MSCs (MSCs) were compared. Bilateral full thickness cartilage defects were created on the medial femoral condyles of 12 rabbits (n = 12). Rabbits were divided into two groups. In one group, the defects in the right knees were repaired using alginate encapsulated MSCs while in the second group, CMSCs were used. The animals were sacrificed and the repaired and control knees were assessed at 3 and 6 months after implantation. Quantitative analysis was performed by measuring the Glycosaminoglycans (GAGs)/total protein content. The mean Brittberg score was higher in the transplanted knees as compared to the untreated knee at 6 months (p  0.05). This study demonstrates that the use of either MSC or CMSC produced superior healing when compared to cartilage defects that were untreated. However, both cells produced comparable treatment outcomes.

    The treatment of major burn injuries are a formidable challenge to the burn surgeon. Early aggressive surgery for deep to full thickness burn injuries is vital in the prevention of infection. The ultimate goal in major burn injuries is to prevent the onset of multi-resistant organisms and achieve early wound cover. The field of tissue engineering can help to expedite the healing of these burn wounds. The development of keratinocyte culture delivery system can be used clinically to fasten the healing process and save many lives.

    The nasal profile and skin thickness in the Caucasian Indian vary from the Oriental Chinese or Malay noses. Reduction rhinoplasty is more common in the Caucasian Indian noses whereas augmentation rhinoplasty is more common in the Oriental Chinese or Malay noses. Graft selection remains the greatest challenge for surgeons performing rhinoplasty. However, the preferred choice as far as possible for nasal reconstruction would be autografts as compared to allografts due to their lower rate of infection, extrusion and they do not induce an immune response. We have evaluated 40 patients and compared our experience with the grafts available over a period of 46 months.

    Normal tracheal mucociliary clearance is the key to maintaining the health and defense of respiratory airway. Therefore the present of cilia and mucous blanket are important for tracheal epithelium to function effectively. In the present study, we prepared a tissue engineered respiratory epithelium construct (TEREC) made of autologous respiratory epithelium cells, fibroblast and fibrin from sheep owns blood which replaced a created tracheal mucosal defect. Scanning electron microscopy (SEM) showed encouraging result where immature cilia were present on the surface of TEREC. This result indicates that engineered respiratory epithelium was able to function as normal tissue.

    OBJECTIVE: To review our experience of total thyroidectomy for bilateral multinodular goitre.
    DESIGN: Prospective open study.
    SETTING: Teaching hospital, Malaysia.
    SUBJECTS: 98 consecutive patients whose bilateral multinodular goitres were treated by total thyroidectomy, January 1998-November 1999.
    INTERVENTION: A revised technique of total thyroidectomy in which more attention than is customary was paid to the exposure and safety of the laryngeal nerves and the parathyroid glands. All patients had at least 1 parathyroid gland autotransplanted.
    MAIN OUTCOME MEASURES: Morbidity and mortality
    RESULTS: There were no injuries to the recurrent laryngeal nerves and no patient developed persistent hypocalcaemia; 27/98 developed transient hypocalcaemia, but this had settled by 6 months postoperatively. 59 patients had persistent symptoms of pressure preoperatively, and these all resolved by 3 months postoperatively. 6 patients had occult malignant disease discovered on histological examination, and 3 developed minor wound infections.
    CONCLUSIONS: Total thyroidectomy is the procedure of choice for bilateral multinodular goitres, provided that sufficient attention is paid to the preservation of the laryngeal nerves and the parathyroid glands.

    The objective of this study was to evaluate the use of Afp1m as a cryopreservative agent for skin by examining the transplanted skin histological architecture and mechanical properties following subzero cryopreservation. Thirty four (34) rats with an average weight of 208 ± 31 g (mean ± SD), were used. Twenty four (n = 24) rats were equally divided into four groups: (i) immediate non-cryopreserved skin autografts (onto same site), (ii) immediate non-cryopreserved skin autografts (onto different sites), (iii) skin autografts cryopreserved with glycerol for 72 h and (iv) skin autografts cryopreserved with Afp1m for 72 h at -4 °C. Rounded shaped full-thickness 1.5-2.5 cm in diameter skin was excised from backs of rats for the autograft transplantation. Non-cryopreserved or cryopreserved auto skin graft were positioned onto the wound defects and stitched. Non-transplanted cryopreserved and non-cryopreserved skin strips from other ten rats (n = 10) were allowed for comparative biomechanical test. All skin grafts were subjected to histological and mechanical examinations at the end of day 21. Histological results revealed that tissue architecture especially the epidermal integrity and dermal-epidermal junction of the Afp1m cryopreserved skin grafts exhibited better histological appearance, good preservation of tissue architecture and structural integrity than glycerolized skin. However, there was no significant difference among these groups in other histological criteria. There were no significant differences among the 4 groups in skin graft mechanical properties namely maximum load. In conclusion, Afp1m were found to be able to preserve the microstructure as well as the viability and function of the skin destined for skin transplantation when was kept at -4 °C for 72 h.

    Split-skin grafting (SSG) is the gold standard treatment for full-thickness skin defects. For certain patients, however, an extensive skin lesion resulted in inadequacies of the donor site. Tissue engineering offers an alternative approach by using a very small portion of an individual's skin to harvest cells for propagation and biomaterials to support the cells for implantation. The objective of this study was to determine the effectiveness of autologous bilayered tissue-engineered skin (BTES) and single-layer tissue-engineered skin composed of only keratinocytes (SLTES-K) or fibroblasts (SLTES-F) as alternatives for full-thickness wound healing in a sheep model. Full-thickness skin biopsies were harvested from adult sheep. Isolated fibroblasts were cultured using medium Ham's F12: Dulbecco modified Eagle medium supplemented with 10% fetal bovine serum, whereas the keratinocytes were cultured using Define Keratinocytes Serum Free Medium. The BTES, SLTES-K, and SLTES-F were constructed using autologous fibrin as a biomaterial. Eight full-thickness wounds were created on the dorsum of the body of the sheep. On 4 wounds, polyvinyl chloride rings were used as chambers to prevent cell migration at the edge. The wounds were observed at days 7, 14, and 21. After 3 weeks of implantation, the sheep were euthanized and the skins were harvested. The excised tissues were fixed in formalin for histological examination via hematoxylin-eosin, Masson trichrome, and elastin van Gieson staining. The results showed that BTES, SLTES-K, and SLTES-F promote wound healing in nonchambered and chambered wounds, and BTES demonstrated the best healing potential. In conclusion, BTES proved to be an effective tissue-engineered construct that can promote the healing of full-thickness skin lesions. With the support of further clinical trials, this procedure could be an alternative to SSG for patients with partial- and full-thickness burns.

    The cultivated epithelial transplantation is a new surgical modality for treating a variety of severe ocular surface disorders. This type of tissue-engineered epithelial sheet provides a rapid epithelial coverage on the corneal surface that reduces inflammation and postoperative complications. Although cultivated corneal epithelial transplantation is an effective surgical strategy, autologous transplantation is limited to unilateral cases. Autologous cultivated oral mucosal epithelial transplantation (COMET) enables surgeons to reconstruct the ocular surface using autologous, non-ocular surface cells, and has opened a new pathway for treating severe, bilateral ocular surface disorders.

    Bone graft is essential in various orthopaedic procedures. Among the many donor sites for harvesting autologous bone graft, the iliac crest has been the most commonly used. However, for foot and ankle procedures the proximal tibia has gained popularity as an alternative donor site due to its anatomic proximity to the primary surgical site. In this article we evaluated the possible complications associated with harvesting proximal tibia bone graft. Our study showed the low incidence of morbidity in harvesting proximal tibia bone graft, thereby providing a good alternative donor for foot and ankle procedures.

    Plasma cell leukaemia (PCL) is an aggressive haematological malignancy which is classified into primary (pPCL) and secondary PCL. A 39-year-old Indian man presented to the Department of Hematology with a 2-week history of fever and lethargy. Clinically, he was pale and febrile. Haemogram revealed bicytopenia with leucocytosis. The peripheral blood film portrayed rouleax formation with 45% of circulating plasma cells. Serum protein electrophoresis and immunofixation revealed IgG lambda paraproteinaemia of 48 g/L. Bone marrow aspirate, flow cytometry and trephine were consistent with IgG lambda pPCL. He was treated with six cycles of bortezomib, thalidomide and dexamethasone combination chemotherapy followed by high-dose melphalan conditioning and autologous stem cell transplant. Currently, he is in complete remission for the past 18 months and is on oral lenalidomide maintenance therapy. Prognosis is often dismal in pPCL with the median overall survival below 1 year if treatment is delayed.
