    Surgical extrusion is defined as the procedure in which the remaining tooth structure is repositioned at a more coronal/supragingival position in the same socket in which the tooth was located originally. Intentional replantation is defined as the deliberate extraction of a tooth and after evaluation of root surfaces, endodontic manipulation and repair, placement of the tooth back into its original position. Tooth autotransplantation is defined as the transplantation of an unerupted or erupted tooth in the same individual, from one site to another extraction site or a new surgically prepared socket. The advent of titanium implant rehabilitation has reduced the use of these treatments in day-by-day clinical practice; however, the re-emerging trend to conserve and preserve natural sound tissues has led to a rediscovery of these treatments. All three distinct surgical methods are closely related, as they act to treat teeth that cannot be predictably treated using other more conventional procedures in endodontics, periodontics and restorative dentistry. Furthermore, these procedures share the same treatment approach and include the atraumatic extraction of a tooth, visual inspection of the tooth/root and its subsequent replantation. The clinical procedures for surgical extrusion, intentional replantation and tooth autotransplantation treatment have undergone several changes in recent years, and currently, there are no clear clinical treatment protocols/guidelines available. The clinician should be aware of the outcome of these treatments. Hence, the aim of this narrative review is to provide the background, clinical procedures and outcomes of surgical extrusion, intentional replantation and tooth autotransplantation.

    INTRODUCTION: Immunosuppressive state due to haematological malignancies and chemotherapy may cause disruption to wound healing despite optimum conventional treatment and standard wound dressing. Non-healing wounds are predisposed to infection whereas chemotherapy dose reductions or interruptions are associated with poor survival.

    BACKGROUND: Mononuclear cells contain progenitor cells including haematopoietic and mesenchymal stem cells, endothelial progenitor cells and fibroblasts which facilitate wound healing through cytokines, growth factor secretions, cell-cell interactions and provision of extracellular matrix scaffolding. Clinical applications of autologous mononuclear cells therapy in wound healing in non-malignant patients with critical limb ischaemia have been reported with remarkable outcome.

    METHODS: We report three patients with haematological malignancies undergoing chemotherapy, who received autologous mononuclear cells implantation to treat non-healing wound after optimum conventional wound care. The sources of mononuclear cells (MNC) were from bone marrow (BM), peripheral blood (PB) and mobilised PB cells (mPB-MNC) using granulocyte colony stimulating factor (G-CSF). The cells were directly implanted into wound and below epidermis. Wound sizes and adverse effects from implantation were assessed at regular intervals.

    RESULTS: All patients achieved wound healing within three months following autologous mononuclear cells implantation. No implantation adverse effects were observed.

    CONCLUSIONS: Autologous mononuclear cells therapy is a feasible alternative to conventional wound care to promote complete healing in non-healing wounds compounded by morbid factors such as haematological malignancies, chemotherapy, diabetes mellitus (DM), infections and prolonged immobility.

    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.

    PURPOSE: This paper aims to review the current evidence for autologous chondrocyte implantation (ACI) generations relative to other treatment modalities, different cell delivery methods and different cell source application.

    METHODS: Literature search was performed to identify all level I and II studies reporting the clinical and structural outcome of any ACI generation in human knees using the following medical electronic databases: PubMed, EMBASE, Cochrane Library, CINAHL, SPORTDiscus and NICE healthcare database. The level of evidence, sample size calculation and risk of bias were determined for all included studies to enable quality assessment.

    RESULTS: Twenty studies were included in the analysis, reporting on a total of 1094 patients. Of the 20 studies, 13 compared ACI with other treatment modalities, seven compared different ACI cell delivery methods, and one compared different cell source for implantation. Studies included were heterogeneous in baseline design, preventing meta-analysis. Data showed a trend towards similar outcomes when comparing ACI generations with other repair techniques and when comparing different cell delivery methods and cell source selection. Majority of the studies (80 %) were level II evidence, and overall the quality of studies can be rated as average to low, with the absence of power analysis in 65 % studies.

    CONCLUSION: At present, there are insufficient data to conclude any superiority of ACI techniques. Considering its two-stage operation and cost, it may be appropriate to reserve ACI for patients with larger defects or those who have had inadequate response to other repair procedures until hard evidence enables specific clinical recommendations be made.

    Various methods, such as vascularized bone transfers, Illizarov bone transport, allogenic bone grafts, bone graft substitutes, are available in treating traumatic bone loss. Free non-vascularised fibular graft is an autografting method that only requires minimal facilities or expertise. However, this method is not popularized due to its avascular property and there is not many reports regarding its use in treating a large traumatic bone loss. We reported a case in our center to demonstrate its possibility of successfully treating the traumatic radial bone loss in pediatric patient. Patient had good recovery with the regain of good range of movement of forearm and there is no harvest site morbidity after two years of follow up.

    Chondrocytes were isolated from articular cartilage biopsy and were cultivated in vitro. Approximately 30 million of cultured chondrocytes per ml were incorporated with autologous plasma-derived fibrin to form three-dimensional construct. Full-thickness punch hole defects were created in lateral and medial femoral condyles. The defects were implanted either with the autologous 'chondrocytes-fibrin' construct (ACFC), autologous chondrocytes (ACI) or fibrin blank (AF). Sheep were euthanized after 12 weeks. The gross morphology of all defects treated with ACFC implantation, ACI and AF exhibited median scores which correspond to a nearly normal appearance according to the International Cartilage Repair Society (ICRS) classification. ACFC significantly enhanced cartilage repair compared to ACI and AF in accordance with the modified O'Driscoll histological scoring scale. The relative sulphated glycosaminoglycans content (%) was significantly higher (p < 0.05) in ACFC when compared to control groups; ACI vs. fibrin only vs. untreated (blank). Results showed that ACFC implantation exhibited superior cartilage-like tissue regeneration compared to ACI. If the result is applicable to the human, it possibly will improve the existing treatment approaches for cartilage restoration in orthopaedic surgery.

    BACKGROUND: Revascularisation therapy is the current gold standard of care for critical limb ischemia (CLI), although a significant proportion of patients with CLI either are not fit for or do not respond well to this procedure. Recently, novel angiogenic therapies such as the use of autologous cellbased therapy (CBT) have been examined, but the results of individual trials were inconsistent.

    OBJECTIVE: To pool all published studies that compared the safety and efficacy of autologous CBT derived from different sources and phenotypes with non cell-based therapy (NCT) in CLI patients.

    METHODS: We searched Medline, Embase, Cochrane Library and ClinicalTrials.gov from 1974-2017. Sixteen randomised clinical trials (RCTs) involving 775 patients receiving the following interventions: mobilised peripheral blood stem cells(m-PBSC), bone marrow mononuclear cells(BM-MNC), bone marrow mesenchymal stem cells(BM-MSC), cultured BM-MNC(Ixmyelocel-T), cultured PB cells(VesCell) and CD34+ cells were included in the meta-analysis.

    RESULTS: High-quality evidence (QoE) showed similar all-cause mortality rates between CBT and NCT. AR reduction by approximately 60% were observed in patients receiving CBT compared to NCT (moderate QoE). CBT patients experienced improvement in ulcer healing, ABI, TcO2, pain free walking capacity and collateral vessel formation (moderate QoE). Low-to-moderate QoE showed that compared to NCT, intramuscular BM-MNC and m-PBSC may reduce amputation rate, rest pain, and improve ulcer healing and ankle-brachial pressure index, while intramuscular BM-MSC appeared to improve rest pain, ulcer healing and pain-free walking distance but not AR. Efficacy of other types of CBT could not be confirmed due to limited data. Cell harvesting and implantation appeared safe and well-tolerated with similar rates of adverse-events between groups.

    CONCLUSION: Implantation of autologous CBT may be an effective therapeutic strategy for no-option CLI patients. BM-MNC and m-PSBC appear more effective than NCT in improving AR and other limb perfusion parameters. BM-MSC may be beneficial in improving perfusion parameters but not AR, however, this observation needs to be confirmed in a larger population of patients. Generally, treatment using various sources and phenotypes of cell products appeared safe and well tolerated. Large-size RCTs with long follow-up are warranted to determine the superiority and durability of angiogenic potential of a particular CBT and the optimal treatment regimen for CLI.

    Bone allografts donated by other individuals offer a viable alternative to autograft. Risks of disease transmission are overcome by sterilizing the bone; unfortunately sterilization methods generally affect bone functional properties including osteogenic potential and biomechanical integrity. This study aimed to determine any enhancement effect when gamma sterilised allografts was impregnated with autologous bone marrow in improving the rate and quality of integration in metaphyseal-tibial defects of rabbits. Almost all subjects showed 50% of the defect being covered by new bones by the third week and smaller residual defect size in the treated group at the fifth week. Hounsfield units at the defect site showed increasing healing in all samples, with the treated group having an apparent advantage although insignificant (p > 0.05). In the histopathological score evaluating healing over cortical and cancellous bone at the fracture site showed only slight variations between the groups (p > 0.05). Therefore no enhanced healing by the autologous bone marrow was observed when added to the bone allografts in treating the unicortical defects.

    CASE: A 22-year-old man sustained a laceration that measured 180 cm, after debridement, over the anterolateral aspect of the right leg following a road traffic accident. The wound was treated with MyDerm (Universiti Kebangsaan Malaysia), a cell-based, bilayered, bioengineered dermal substitute that contains no animal-derived components and is fully autologous. For its construction, only a small area of skin was harvested from the left groin, which was closed primarily with absorbable sutures.

    CONCLUSION: MyDerm is an alternative option for the treatment of a massive skin defect in patients who desire removal of only a negligible amount of skin from the donor site and when use of an autograft is insufficient.

    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.

    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.

    Introduction: Distraction osteogenesis has been used effectively in the management of tibia non-unions with skeletal defect. A retrospective case series study of the infected non-union tibia managed with acute docking in a rail fixation system was conducted at a tertiary care hospital in South India. It was designed to evaluate the use of autologous bone graft at the docking site in achieving an early union with a seven years follow-up period.

    Materials and Methods: From 2010 to 2017, a total of 19 patients with infected tibia non-union and a bone defect less than 3cm, were treated with debridement and a monolateral frame fixation with acute shortening and lengthening. The patients were divided into two groups: one in which no bone graft was used at the docking site during early years of the study; and a later group in which autologous bone graft was used at the acute docking site primarily in addition to compression. Consolidation at the docking site was assessed both radiographically and clinically, and the results were statistically analysed.

    Results: There were 12 patients in Group I without bone graft, where consolidation at the docking site was noted after a mean duration of 22.08 ± 3.87 weeks. There were seven patients in Group II with bone graft, where the mean time for docking site consolidation was significantly lower at 16.57 ± 3.82 weeks. No docking site complications were noted in either group.

    Conclusion: Primary autologous bone graft enhances docking site consolidation in acute shortening. The routine use of bone graft at the docking site in acute shortening will expedite the docking site union with reduction of treatment time.

    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.

    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.

    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.

    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.
