Giant cell tumours of bone are best treated by extended curettage and filling in of the defect with cement or bone graft. In more advanced stages, when there is extensive loss of cortical bone cover, containment of the filling material is not possible and resection and reconstruction is required. We report a case of a recurrent giant cell tumour of the distal tibia in a 21 year old female with extensive cortical bone loss in which polypropylene surgical mesh was used to contain the bone cement, thus avoidi

Synovial sarcoma of the extremities is an uncommon type of soft tissue sarcoma occurring predominantly in young adults at the para articular regions. We present a series of 10 patients with an average age of 44 years and include a follow up of 39 months. Eight patients had a surgical procedure for a mistaken benign lesion. In contrast to other soft tissue sarcomas, the swellings were associated with pain and most were fixed to the underlying structures. Five patients had a local recurrence after many years, stressing the necessity for close and long term follow up in these patients.

The goal of treatment in distal radius fracture is to restore the anatomy of the distal radius, however the criteria currently used to evaluate the quality of reduction are based on Western based published figures. This goal of this study was to investigate whether there are variations in the morphology of the distal radius among the multiracial population of Malaysia. Consecutive normal wrist radiographs of patients who presented to the accident and emergency unit in three major hospitals in Malaysia were measured. . The palmar tilt of the distal radius averaged 12.6o ± 3.55o, and the radial inclination averaged 25.1o ± 3.42o. The ulnar variance averaged – 0.1 ± 1.31mm, 38.4% of the patients had neutral ulnar variance, 28.8% have negative ulnar variance and 32.9% have positive ulnar variance. Our results indicate that distal radius morphometric parameters in the Malaysian population are comparable to Western figures.

This report details the case of a 12-year-old girl with a painful, progressive swelling of the medial portion of the clavicle with no history of trauma or other constitutional symptoms. All laboratory investigations were normal except for an elevated erythrocyte sedimentation rate (ESR). Initial plain radiographs showed a destructive lesion with magnetic resonance imaging showing features of malignancy. Biopsies revealed osteomyelitis, but with negative bacterial cultures and no evidence of malignancy. Treatment with antibiotics did not result in a favourable response. Over time, the swelling increased in size with episodic exacerbations of pain. Follow-up radiographs showed sclerosis and hyperostosis. After five years, this was recognized as non-bacterial chronic recurrent osteomyelitis of the clavicle.

INTRODUCTIONUltrasonographic evaluation of patients in cardiac arrest is currently not protocolised in the advanced cardiac life support (ACLS) algorithm. Potentially reversible causes may be identified using bedside ultrasonography that is ubiquitous in most emergency departments (EDs). This study aimed to evaluate the incidence of sonographically detectable reversible causes of cardiac arrest by incorporating an ultrasonography protocol into the ACLS algorithm. Secondary objectives include rates of survival to hospital admission, hospital discharge, and 30-day mortality.

MATERIALS AND METHODSWe conducted a prospective study using bedside ultrasonography to evaluate for potentially reversible causes in patients with cardiac arrest at the ED of National University Hospital, Singapore, regardless of the initial electrocardiogram rhythm. A standardised ultrasonography protocol was performed during the 10-second pulse check window.

RESULTSBetween June 2015 and April 2016, 104 patients were recruited, corresponding to 65% of all out-of-hospital cardiac arrest patients conveyed to the ED. Median age was 71 years (interquartile range, 55 to 80) and 71 (68.3%) patients were male. The most common rhythm on arrival was asystole (45.2%). Four (3.8%) patients had ultrasonographic findings suggestive of massive pulmonary embolism while 1 received intravenous thrombolysis and survived until discharge. Pericardial effusion without tamponade was detected in 4 (3.8%) patients and 6 (5.8%) patients had intra-abdominal free fluid. Twenty (19.2%) patients survived until admission, 2 of whom (1.9%) survived to discharge and beyond 30 days.

CONCLUSIONBedside ultrasonography can be safely incorporated into the ACLS protocol. Detection of any reversible causes may alter management and improve survival in selected patients.

Patients with extensive malignancies involving the femur often require total femoral replacement when their limbs can be salvaged. Reported series are small and involve heterogeneity of tumours. We present nine patients with osteosarcomas of the femur treated at our institution between 2003 and 2010 with a mean follow-up of 27 (6 to 56) months. Their ages ranged from 9 to 17 (mean 14 years). They had large volume tumours (mean 911 cm3 ) and presented late with a mean of 5.5 months from the onset of symptoms to definitive treatment. All patients underwent resection and total femur replacement. Six patients have died and two are alive with good function at the time of this report. One was lost to follow-up. These patients require a high level of treatment care and have a guarded prognosis

INTRODUCTIONTreatment of acute lymphoblastic leukaemia (ALL) using intensive chemotherapy has resulted in high cure rates but also substantial morbidity. Infective complications represent a significant proportion of treatment-related toxicity. The objective of this study was to describe the microbiological aetiology and clinical outcome of episodes of chemotherapy-induced febrile neutropaenia in a cohort of children treated for ALL at our institution.

MATERIALS AND METHODSPatients with ALL were treated with either the HKSGALL93 or the Malaysia-Singapore (Ma-Spore) 2003 chemotherapy protocols. The records of 197 patients who completed the intensive phase of treatment, defined as the period of treatment from induction, central nervous system (CNS)-directed therapy to reinduction from June 2000 to January 2010 were retrospectively reviewed.

RESULTSThere were a total of 587 episodes of febrile neutropaenia in 197 patients, translating to an overall rate of 2.98 episodes per patient. A causative pathogen was isolated in 22.7% of episodes. An equal proportion of Gram-positive bacteria (36.4%) and Gram-negative bacteria (36.4%) were most frequently isolated followed by viral pathogens (17.4%), fungal pathogens (8.4%) and other bacteria (1.2%). Fungal organisms accounted for a higher proportion of clinically severe episodes of febrile neutropaenia requiring admission to the high-dependency or intensive care unit (23.1%). The overall mortality rate from all episodes was 1.5%.

CONCLUSIONFebrile neutropaenia continues to be of concern in ALL patients undergoing intensive chemotherapy. The majority of episodes will not have an identifiable causative organism. Gram-positive bacteria and Gram-negative bacteria were the most common causative pathogens identified. With appropriate antimicrobial therapy and supportive management, the overall risk of mortality from febrile neutropaenia is extremely low.

Acquired radial clubhand deformity can be a consequence of large bone gap left by premature extensive radius osteomyelitis sequestrectomy. Single-bone forearm reconstruction is a salvage procedure when other motionpreserving techniques are not feasible. Here we present a child who developed radial clubhand deformity after an untimely sequestrectomy of radius diaphysis. In view of limited microsurgical expertise in our centre, single-bone forearm procedure was done utilising simple Kirshner wires to achieve radio-ulnar fusion. The procedure resulted in painfree stable wrist, restoration of hand function and improved cosmesis.

Delayed post-operative spinal epidural haematoma (DPSEH) is diagnosed when the onset of symptoms is more than three days from the index surgery. DPSEH is a rare but serious complication of spinal surgery. Missed diagnosis will result in irreversible neurological deficit which may lead to permanent disabilities. We report two cases of DPSEH who presented with worsening neurological deficit four days after the index surgery. Magnetic resonance imaging (MRI) showed the presence of an epidural haematoma compressing the spinal cord. Surgical evacuation of haematoma were performed for both patients. Both patients experienced neurological improvement. Surgeons should have high index of suspicion to identify delayed onset of spinal epidural haematoma (SEH) and timely intervention should be taken to avoid irreversible neurological damage.
