    Ovine articular chondrocytes were isolated from cartilage biopsy and culture expanded in vitro. Approximately 30 million cells per ml of cultured chondrocytes were incorporated with autologous plasma-derived fibrin to form a three-dimensional construct. Full-thickness punch hole defects were created in the lateral and medial femoral condyles. The defects were implanted with either an autologous 'chondrocyte-fibrin' construct (ACFC), autologous chondrocytes (ACI) or fibrin blanks (AF) as controls. Animals were killed after 12 weeks. The gross appearance of the treated defects was inspected and photographed. The repaired tissues were studied histologically and by scanning electron microscopy analysis. All defects were assessed using the International Cartilage Repair Society (ICRS) classification. Those treated with ACFC, ACI and AF exhibited median scores which correspond to a nearly-normal appearance. On the basis of the modified O'Driscoll histological scoring scale, ACFC implantation significantly enhanced cartilage repair compared to ACI and AF. Using scanning electron microscopy, ACFC and ACI showed characteristic organisation of chondrocytes and matrices, which were relatively similar to the surrounding adjacent cartilage. Implantation of ACFC resulted in superior hyaline-like cartilage regeneration when compared with ACI. If this result is applicable to humans, a better outcome would be obtained than by using conventional ACI.

    Immune Thrombocytopenia Purpura (ITP) secondary to vaccinations is rare, especially after autologous hematopoietic stem cell transplantation (HSCT). A 31-yearold female received autologous HSCT for relapsed Hodgkin Disease, with platelet engraftment at Day+14. One week after receiving second scheduled vaccinations, she developed severe thrombocytopenia (3x109/L) associated with pharyngeal hematoma. Bone marrow (BM) examinations were consistent with ITP, possibly secondary to Influenza vaccine. Platelet increment was poor despite high dose corticosteroids, intravenous immunoglobulin (IVIG), Danazol and Eltrombopag. A repeated BM biopsy was in agreement with ITP. Re-treatment with tapering doses of prednisolone resulted in stable platelet counts at 120x109/L a year later.

    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.

    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.

    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.

    Obstruction remains as an important cause of failure in the eruption of a tooth. In this article, a 15-year-old girl was presented with retained upper left primary canine (63) and first primary molar (64), while the contralateral permanent canine (13) and premolars (14 and 15) have erupted. Upon radiographic examination, a mass which was diagnosed later to be compound odontome was detected. The treatment consisted of surgical removal of the odontome, extraction of the primary canine (63) and left permanent canine (23), and transplantation of the permanent canine (23). The management of this case and the literature related to autotransplantation are discussed.

    Mantle cell lymphoma (MCL) is a rare, aggressive subtype of non-Hodgkin lymphoma with a poor prognosis and high recurrence rate. It seldom affects the Waldeyer's ring let alone the nasopharynx. Patients usually present at late stages of the disease leading to poor failure-free and overall survival rates. Intensive chemotherapy regimes and autologous stem cell transplantation have reported increased survival rates. We report a relapsed case of nasopharyngeal MCL, which previously occurred in the gastrointestinal tract. The patient had undergone a hemicolectomy for colon intussusception secondary to the intraluminal lymphoma mass. He was unable to complete the treatment regime for MCL due to the adverse side effects. Oropharyngeal mass was discovered during routine outpatient follow-up, which was confirmed as nasopharyngeal MCL. We discuss the prognosis, disease progression, and possible treatments.

    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.

    Pterygium is a common external eye problem. It is more frequently seen in tropical areas regions where exposure to ultraviolet sunlight is high. Clinically, a pterygium is a wing shaped fibrovascular growth arising from the bulbar conjunctiva onto the superficial cornea. Complications of pterygium include decreased in visual acuity, dryness, foreign body sensation and persistent redness. Surgical management is the mainstay of treatment for this condition. Numerous surgical techniques have been described in the treatment of pterygium. They include the bare sclera technique, simple direct conjunctival closure, rotational conjunctival graft and conjunctival autograft. Additional treatment to some of these techniques may include the use of beta particle therapy and antimetabolite therapy. Despite the wide range of surgical procedures described for its treatment, the main concern from these procedures has been the recurrence, which could be as high as 30% to 70%. Recurrent pterygium is often accompanied by increased conjunctival inflammation and accelerated corneal involvement. Repeated surgical procedures often only worsen the situation, as loss of conjunctival tissue and scarring can result in obliteration of the fornices and mechanical restriction of extraocular movements, with clinically significant diplopia. In Hospital Tengku Ampuan Afzan, pterygium excision is the most common surgical procedure after cataract extraction. We reviewed patients who had undergone pterygium surgery in HTAA in order to determine the most effective surgical method that could minimize recurrence. PURPOSE: To compare success rates of various excision techniques performed for primary and recurrent pterygium in Hospital Tengku Ampuan Afzan, Kuantan, Pahang.
    METHODS: The outcome of 47 cases of pterygia (44 primary and 3 recurrent) excised with various techniques between January 2004 to September 2004 was retrospectively reviewed. Six clinical specialists and four trainees performed the surgical procedures. Outcome was evaluated in terms of recurrence of pterygia onto the cornea. RESULTS: The mean follow up was 3.04 months (range, 1-7 months). All pterygia were morphologically graded as intermediate or fleshy type except one. Four types of pterygium excision techniques were performed. Twenty-four cases had bare sclera, seventeen cases had conjunctival autograft transplantation, six cases had direct conjunctival closure and one had amniotic membrane transplantation done. Recurrence of pterygia occurred in thirteen eyes. Twelve cases from primary pterygia group and one case from recurrent group recurred. Recurrence rate was noted to be higher in direct conjunctival closure (4 out of 6 cases) and lowest in conjunctival autograft transplantation (2 out of 17 cases). Recurrence rate for bare sclera technique was noted to rank second in this study (6 out of 24 cases). In five cases of recurrence, subconjunctival tissue invasions were more than 1 mm but further surgical interventions were not needed at the time of this review was done. CONCLUSIONS: Conjunctival autografting was found to have less recurrent rate when compared with other techniques. The bare sclera technique was quoted to be associated with higher recurrence rate in other literatures. Interestingly in our series, recurrence rate for direct conjunctival closure technique was higher when compared to the former technique. This may be related to inadequate excision of pterygia tissue, which led to direct apposition of abnormal tissue to the cornea in the direct conjunctival closure technique. Even though the bare sclera technique is associated with a higher recurrence rate, it is still the preferred excision technique. This could be because it is less time consuming and technically easier to perform. Based on this study, conjunctival autografting should be the surgical procedure of choice for pteryigum in order to minimise the risk of recurrence.

    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.

    Despite remarkable mechanical durability and strength, hyaline cartilage has very limited capacity for self-repair when injured and over time, may degenerate to osteoarthritis. We evaluated the most significant mile stones attained, in the pursuit of cure for cartilage defects and osteoarthritis. The basic treatment options include: Natural or physical therapy, medications, nutritional supplements, nutriceuticals and chondroprotective agents. Next are repairs and replacements, which include surgical procedures: Debridement/chondroplasty, microfracturing, mosaicplasty, periosteum transplantation, osteochondral autografting and allografting, high tibial osteotomy and total knee arthroplasty. But, current trend has shifted from repair, replacement, to most recently regeneration. Regenerations include the cell and gene therapies. While cell therapy involves the use of cells isolated from different tissues to cause regeneration of cartilage; gene therapy involves the selection of appropriate gene and optimal vector to incorporate cDNA. There has been much positivity reported with big animal models, which has led to several ongoing clinical trials. Translations of these findings hold high promises, though not without inherent regulatory hurdles. Considering the initial success rates, there are increasing hopes of realizing these treatments from bench to bedsides. Significant improvements in the treatment of cartilage degenerations and osteoarthritis have been made so far, but no gold standard delineated.

    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.

    Osteoarthritis (OA) is a degenerative joint disease that affects a lot of people worldwide. Current treatment for OA mainly focuses on halting or slowing down the disease progress and to improve the patient's quality of life and functionality. Autologous chondrocyte implantation (ACI) is a new treatment modality with the potential to promote regeneration of worn cartilage. Traditionally, foetal bovine serum (FBS) is used to expand the chondrocytes. However, the use of FBS is not ideal for the expansion of cells mean for clinical applications as it possesses the risk of animal pathogen transmission and animal protein transfer to host. Human platelet lysate (HPL) appears to be a suitable alternative to FBS as it is rich in biological factors that enhance cell proliferation. Thus far, HPL has been found to be superior in promoting chondrocyte proliferation compared to FBS. However, both HPL and FBS cannot prevent chondrocyte dedifferentiation. Discrepant results have been reported for the maintenance of chondrocyte redifferentiation potential by HPL. These differences are likely due to the diversity in the HPL preparation methods. In the future, more studies on HPL need to be performed to develop a standardized technique which is capable of producing HPL that can maintain the chondrocyte redifferentiation potential reproducibly. This review discusses the in vitro expansion of chondrocytes with FBS and HPL, focusing on its capability to promote the proliferation and maintain the chondrogenic characteristics of chondrocytes.

    Mesenchymal stem cells (MSCs) represent a promising alternative form of cell-based therapy for cartilage injury. However, the capacity of MSCs for chondrogenesis has not been fully explored. In particular, there is presently a lack of studies comparing the effectiveness of MSCs to conventional autologous chondrocyte (autoC) treatment for regeneration of full-thickness cartilage defects in vivo.

    This study tested the possibility of adrenal autotransplantation in rats. Since the cortex and the medulla of the adrenal gland were from different origin embryologically, either whole adrenal glands (ADR), or capsule and cortex (CAP) or medulla (MED) were autotransplanted in the subcutaneous tissue. The functions of regenerated adrenal nodules were tested by measuring plasma corticosterone levels every fortnight. At the end of 9 weeks the rats were exposed to hypovolemic shock followed by naloxone injection to reverse the shock response. Results showed that rats transplanted with either cortex or whole adrenal started secreting corticosterone at 5 weeks post-transplantation (107.73 +/- 21.98 ng/ml, 126.04 +/- 48.41 ng/ml, respectively). Corticosterone levels increased to the value which were not significantly different from control by 9 weeks post-transplantation. However, rats transplanted with adrenal medulla showed very low corticosterone levels. Nine weeks post-transplantation, the mean blood pressure (MBP) of the CAP group was 135 +/- 13 mmHg and was not significantly different from sham-operated controls, whereas MBP of MED group was significantly lower than sham-operated animals (99 +/- 11 mmHg versus 141 +/- 9 mmHg). The MBP of the ADR group was also lower compared to sham-operated controls (112 +/- 17 mmHg P < 0.05). The MBP of the adrenal group was not statistically significant compared to the CAP group. After 1% body weight haemorrhage, the MBP decreased significantly in ADR (45 +/- 5 mmHg, P < 0.05) and MED group (36 +/- 9 mmHg, P < 0.001) compared to sham-operated rats (78 +/- 11 mmHg) but not in the CAP (56 +/- 9 mmHg). It was concluded that autotransplanted whole adrenal or adrenocortical tissues survived subcutaneously and produced sufficient corticosterone to alleviate haemorrhagic shock. Adrenal medullary tissue failed to regenerate subcutaneously and the presence of adrenal medullary tissue may suppressed the growth of transplanted adrenal gland.
