    We present an unusual case, where the medial meniscus does not coincide with the embryological development of the formation of a discoid cartilage. A fairly, careful perusal of English literature since 1945 to date makes us feel that the following case merits recording. The meniscus had a normal anterior horn attached to the intercondylar area, in front of the anterior cruciate ligament. Medially, it was attached to the capsule and the condylar surface of the medial tibial plateau. The posterior horn was rounded, smooth, and floating free of any attachments. It was approximately 2 cms in length, semilunar in shape, and extended posteriorly up to the anterior margin of the medial collateral ligament. The rest of the medial tibial plateau had no other protective covering.

    OBJECTIVE: To determine in situ using TEM the balance of apoptosis and necrosis in the articular cartilage of patients with inflammatory (rheumatoid arthritis and seronegative spondyloarthritis) and degenerative (osteoarthritis) joint diseases and to establish possible correlation between the cell death rate and the matrix vesicles formation.
    METHODS: Cartilage samples of the knee joint were obtained from patients with rheumatoid arthritis (RA, 18 cases), osteoarthritis (OA, 22 cases), Reiter's disease (RD, 9 cases), peripheral form of the ankylosing spondyloarthritis (AS, 6 cases) and psoriatic arthritis (PA, 6 cases) during arthroscopy or knee surgery. Normal samples taken from autopsy cases without a history of joint diseases were used as control. Samples were processed for TEM with subsequent semi-quantitative estimation of the cell death rate in the superficial, middle and deep zone of non-calcified articular cartilage, and computer-aided ultramorphometric evaluation of the matrix vesicles of different types.
    RESULTS: Both apoptotic and necrotic cell death could be identified in the cartilage of patients with inflammatory joint diseases, including seronegative spondyloarthritides and degenerative arthropathies. Apoptosis dominated over necrosis in all examined arthritides, including RA patients in which necrosis of the chondrocyte was the most frequent among arthropathies, while the highest apoptotic cell death rate was discovered in OA in which it correlated with the volume and numeric density of the matrix vesicles. These data provide evidence that apoptosis may contribute to the cartilage breakdown not only in RA and OA but also in the seronegative spondyloarthritides, which had a significantly higher apoptotic rate than the normal cartilage.

    Acquired subglottic stenosis is a compication or neonatal endotracheal intubation. Although it is rare, it contributes significantly to the morbidity and physical well being of post extubated neonates. A 20-day old neonate, ventilated for meconium aspiration syndrome and persistent fetal circulation, presented with marked stridor and respiratory embarrassment. A stenosed subglottic area was found on rigid bronchoscopy. Anterior cricoid split was performed to relieve the obstruction. He is asymptomatic post operatively.

    Endochondral pseudocyst of the auricle is an uncommon condition that affects predominantly Chinese males, with many reports studying this condition in homogenous Chinese populations. There have been few large-scale reports describing the features of this disease among the other Asian groups. In one of the largest series described to date, we report the epidemiological features, clinico-pathologic characteristics, and success of surgical treatment in 40 patients of different Asian groups presenting with pseudocyst of the auricle. Results showed a Chinese predominance (90 per cent), followed by Malays (five per cent) and Eurasians (five per cent). All had unilateral presentations apart from one patient. Most (55 per cent) presented within two weeks of auricular swelling. Few (10 per cent) had a history of trauma. The pseudocysts predominantly affected the concha (61 per cent). Surgery comprised excision of the anterior wall followed by local pressure application. Only 2.5 per cent had recurrence after surgery. These findings confirm earlier understood features of this disease while revealing some notable variations.

    This study was to assess collagen type II and collagen type I gene expression in tissue-engineered human auricular: cartilage formed via tissue engineering technique. Large-scale culture expansions were transformed into 3D in vitro construct and were implanted subcutaneously on the dorsal of athymic mice. After 8 weeks, explanted construct was processed in the same manner of native cartilage to facilitate cells for gene expression analysis. Isolated cells from in vivo construct demonstrated expression of type II collagen gene comparable to native cartilage. This study verified that tissue-engineered auricular cartilage expressed cartilage specific gene, collagen type II after in vivo maturation.

    We have previously formulated an optimized human chondrocytes growth medium based on 2% fetal bovine serum supplementation. For clinical usage, the animal serum must be replaced by patient own serum. We investigated the effects of human serum concentration for human nasal septum chondrocytes monolayer culture and cartilage reconstruction. Human serum demonstrated a dose dependent manner in promoting chondrocytes growth and cartilage engineering.

    To date there is no optimal approach to reconstruct an external ear. However, advances in tissue engineering technologies have indicated that in vitro autologous elastic cartilage might be of great importance in the future treatment of these patients. The aim of this study was to observe monolayer expansion of auricular cartilage and to evaluate engineered cartilage using standard histochemical study.

    Patient own fibrin may act as the safest, cheapest and immediate available biodegradable scaffold material in clinical 1 tissue engineering. This study investigated the feasibility of using patient own fibrin isolated from whole blood to construct a new human cartilage, skin and bone. Constructed in vitro tissues were implanted on the dorsal part of the nude mice for in vivo maturation. After 8 weeks of implantation, the engineered tissues were removed for histological analysis. Our results demonstrated autologous fibrin has great potential as clinical scaffold material to construct various human tissues.

    Treatment of articular cartilage lesions remains a clinical challenge. The uses of prosthetic joint replace allograft and/or autograft transplant carry a risk of complications due to infection, loosening of its component, immunological rejection and morbidity at the donor site. There has been an increasing interest in the management of cartilage damages, owing to the introduction of new therapeutic options. Tissue engineering as a method for tissue restoration begins to provide a potential alternative therapy for autologous grafts transplantations. We aimed to evaluate how well a tissue engineered neocartilage implant, consist of human articular chondrocytes cultured with the presence of autologous serum and mixed in a fresh fibrin derived from patient, would perform in subcutaneous implantation in athymic mice.

    Animal serum is commonly used in chondrocytes culture expansion to promote cell proliferation and shorten the time lag before new tissue reconstruction is possible. However, animal serum is not suitable for regeneration of clinical tissue because it has potential risk of viral and prion related disease transmission particularly mad cow disease and foreign protein contamination that can stimulate immune reaction leading to graft rejection. In this context, human serum as homologous supplement has a greater potential as growth promoting agents for human chondrocytes culture.

    Autologous cells are usually preferred in treating damaged tissue to avoid risks of immunological rejection and transmitting infectious diseases. Since only limited amount of tissue can be obtained without causing morbidity at the donor site, in vitro expansion of isolated cell is essential in order to acquire sufficient number of cells to reconstruct neocartilage. The aim of this study was to examine whether serial expanded chondrocytes can be use to generate neocartilage in vivo.

    The regulation roles of insulin-like growth factor-1 (IGF-1) with basic fibroblast growth factor (bFGF) and transforming growth factor beta 2 (TGFbeta2) in human nasal septum chondrocytes monolayer culture and cartilage engineering was investigated in this study. The role of IGF-1 with bFGF and TGFbeta2 was investigated by measuring chondrocyte growth kinetic and collagen genes expression. IGF-1 together with bFGF and TGFbeta2 promote cartilage tissue engineering, increase type II collagen expression and enhance the histological features of engineered cartilage.

    Culture media supplemented with animal serum e.g. fetal bovine serum; FBS is commonly used for human culture expansion. However, for clinical application, FBS is restricted as its carry a risk of viral or prion transmission. Engineering autologous cartilage with autologous human serum supplementation is seen as a better solution to reduce the risk of transmitting infectious diseases and immune rejection during cartilage transplantation. The purpose of this study is to establish and compare the effects of 10% autologous human serum (AHS) and 10% FBS on the growth of chondrocytes and the formation of tissue engineered human articular cartilage.

    Sleeve fracture of the inferior pole of the patella is a rare and distinctive fracture in children with few published reports. These fractures are frequently misdiagnosed and neglected. We highlight a case of a neglected and misdiagnosed sleeve fracture of the patella in an eleven-year-old boy. This was initially diagnosed as an avulsion fracture of the tibial tubercle. A good outcome was achieved after open reduction and internal fixation.
