INTRODUCTION: XELOX is non-inferior to FOLFOX-4 as a first-line treatment for metastatic colorectal cancer. This study compares the costs associated with XEL0X+/-bevacizumab versus FOLFOX4+/-bevacizumab in a non-reimbursed, out of pocket Philippine health care system.
METHODS: This is a cost-minimization analysis using Philippine General Hospital as base case and a typical Filipino patient of 60 kg with BSA 1.66. The outcome data were derived from the N016966 trial. These included the drugs capecitabine, 5-fluorouracil, oxaliplatin, and bevacizumab (BEV); chemotherapy cycles and corresponding hospital admission for each regimen; resources associated with treatment of adverse events such hospital days, ambulatory consultations, concomitant
medication, and central venous line insertion/removal, with costs and charges based on the local setting.
RESULTS: Highest cost (direct and/or indirect) was for FOLFOX4+BEV, followed by XEL0X+BEV, FOLFOX4, and then XELOX. The use of XELOX resulted in a cost saving of PhP 158,642 per patient compared with FOLFOX4. The use of XEL0X+BEV resulted in a cost saving of PhP 186,144 per patient compared with FOLFOX4+BEV.
CONCLUSION: XEL0X+/-BEV is less costly than FOLFOX4-F/-BEV in an out-of-pocket Philippine tertiary hospital setting from the patient's perspective.

INTRODUCTIONSevere acute respiratory syndrome (SARS) is a newly emerged atypical pneumonia caused by the SARS-associated coronavirus (SARS-CoV). Chest radiographic appearances have been reported as non-specific, ranging from normal to peribronchial thickening and ill-defined airspace shadowing. This study is a retrospective review of chest radiographic findings in children with suspected and probable SARS during the 2003 outbreak in Singapore.

MATERIALS AND METHODSWe focused on children admitted to the SARS treatment ward from March 2003 to May 2003. Chest radiographs of children admitted with suspected or probable SARS as well as other febrile illness during this period were retrospectively and independently reviewed by 3 radiologists. The radiographs were randomised and anonymised before interpretation. Subsequently, we identified the radiographs of patients who were categorised as suspected or probable SARS. We present our findings in these patients' radiographs.

RESULTSA total of 67 patients' serial chest radiographs were interpreted. Of these, we subsequently selected those patients with suspected or probable SARS for analysis. The radiographic abnormalities in suspected or probable SARS patients consisted of patchy ground glass opacities or patchy airspace consolidation. The abnormalities had a predominantly lower zone distribution on chest radiographs, followed by mid-zone involvement. There was a slight preponderance of peripheral zone involvement. There was equal distribution of abnormalities in both lungs. All the children with radiographic abnormalities made uneventful recoveries and had normal radiographs on follow-up review.

CONCLUSIONSIn children, SARS appears to have a relatively mild and nonspecific pattern of respiratory illness. The radiographic features in children with suspected or probable SARS in our study were comparable to other clusters of paediatric patients during initial presentation. It is difficult to distinguish SARS in children from other viral pneumonias on radiographic features alone. Positive travel history to endemic regions or positive contact history, and laboratory findings of lymphopaenia, leukopaenia and thrombocytopaenia are important clues.

INTRODUCTIONRight siting has been actively advocated to mitigate rising healthcare costs as well as to free up tertiary resources for the provision of care to more complex patients, research and education. There are, however, concerns that in a block budget setting right siting will reduce patient volumes, thus impacting on subsequent funding allocations and also patient revenues. We sought to determine through modelling and simulation the financial and volume impacts of right siting of endocrinology outpatients in a large tertiary hospital in Singapore.

MATERIALS AND METHODSData were collected prospectively on patient casemix including complexity (complex defined as requiring specialist care), time required for consultations and revenues garnered. The data were used to simulate 2 scenarios: right siting of all simple cases with freed up resources directed to research and teaching (research scenario) and right siting of all simple cases with replacement by complex cases (service scenario).

RESULTSThe department sees an estimated 33,000 outpatients per year with a total annual outpatient revenue of $8.6 million. The research scenario would see a decline in patient volume to 11,880 cases per year which would result in a corresponding decrease in revenue of $5 million and freeing up of 2.8 hours/ week for each staff. The service scenario yields a drop in patient volume of 9500 per annum and a drop in revenue of $1.9 million.

CONCLUSIONRight siting reduces tertiary care patient volumes and revenues and may discourage right siting efforts. A viable business model for the tertiary institutions is needed to facilitate support for right siting.

INTRODUCTIONPolymerase chain reaction (PCR)-based molecular techniques are useful adjunctive tools in the diagnosis of cutaneous T-cell lymphomas (CTCL). This study compares the sensitivity of PCR analysis of the T-cell receptor-gamma (TCR-gamma) gene rearrangements using conventional polyacrylamide gel electrophoresis (PCR-PAGE) and fluorescent capillary electrophoresis (PCR-FCE).

MATERIALS AND METHODSA total of 22 paraffin blocks were analysed using PCR-PAGE and PCR-FCE. There were 17 cases of mycosis fungoides (MF), 4 cases of non-MF CTCL and 1 case of lymphoblastic leukaemia.

RESULTSComplete agreement was obtained between PCR-PAGE and PCR-FCE in 19 of the 22 cases, giving a concordance rate of 86.4%. PCR-FCE had a higher sensitivity of 77.3%, compared to 63.6% for PCR-PAGE, allowing the detection of 3 additional cases of clonal T-cell rearrangements, which had equivocal or polyclonal bands on PAGE. Two of these 3 cases were in erythrodermic MF patients. PCR-FCE also allowed the detection of matching clones in serial specimens taken from different sites and at different time intervals in patients with MF. However, matching clones from different specimens can be achieved qualitatively in PCR-PAGE by running and comparing these on the same polyacrylamide gel block.

CONCLUSIONSBoth PCR-PAGE and PCR-FCE are useful in detecting T-cell clones in CTCL, with both methods being comparable in sensitivity and showing a high concordance rate of 86.4%. PCR-FCE has the added advantage of exhibiting semiquantitative properties, which may be important in early or erythrodermic MF cases, but the requirement for sophisticated and costly machinery limits its availability to high-capacity laboratories. The well-established PCR-PAGE method is a suitable alternative in routine clinical applications.

A 63-year-old gentleman presented with a one-year duration of progressive neurogenic claudication. However, unlike most patients who presents with leg symptoms, his pain was felt in his scrotal and perianal region. This was exacerbated with walking and standing, but he had immediate relief with sitting. An magnetic resonance imaging (MRI) was performed which showed severe central canal stenosis. An L3/4 and L4/5 surgical decompression and a transforaminal lumbar interbody fusion was performed, and the patient made good recovery with immediate resolution of symptoms. Although rare, spinal stenosis should be considered a differential when approaching a patient with perianal and scrotal claudication, even in the absence of leg claudication. An MRI is useful to confirm the diagnosis. This rare symptom may be a sign of severe cauda equina compression and we recommend decompression with predictable good results.

INTRODUCTIONA 22-year-old Malay soldier developed dapsone hypersensitivity syndrome 12 weeks after taking maloprim (dapsone 100 mg/pyrimethamine 12.5 mg) for anti-malarial prophylaxis.

CLINICAL PICTUREHe presented with fever, rash, lymphadenopathy and multiple-organ involvement including serositis, hepatitis and thyroiditis. Subsequently, he developed congestive heart failure with a reduction in ejection fraction on echocardiogram, and serum cardiac enzyme elevation consistent with a hypersensitivity myocarditis.

TREATMENTMaloprim was discontinued and he was treated with steroids, diuretics and an angiotensin-converting-enzyme inhibitor.

OUTCOMEHe has made a complete recovery with resolution of thyroiditis and a return to normal ejection fraction 10 months after admission.

CONCLUSIONIn summary, we report a case of dapsone hypersensitivity syndrome with classical symptoms of fever, rash and multi-organ involvement including a rare manifestation of myocarditis. To our knowledge, this is the first case of dapsone-related hypersensitivity myocarditis not diagnosed in a post-mortem setting. As maloprim is widely used for malaria prophylaxis, clinicians need to be aware of this unusual but potentially serious association.

INTRODUCTIONRecurrent non-immune fetal hydrops (NIH) has been reported in the literature but is a rare entity, with fewer than 6 reported cases so far. It has been postulated to be related to a recessive gene.

CLINICAL PICTUREWe report a case of recurrent fetal hydrops in a multigravida with no medical history of note. She presented in her current pregnancy with a significant history of having 4 (out of 7) previous pregnancies affected by hydrops.

TREATMENTAll the affected pregnancies resulted in mid-trimester pregnancy termination (MTPT) following diagnosis in the second trimester. Previous investigations for hydrops did not yield any obvious cause.

OUTCOMEHer most recent pregnancy was unaffected. We discuss the possible differential diagnoses and the likelihood of autosomal recessive metabolic diseases being the aetiological factor.

CONCLUSIONRare causes of fetal hydrops need to be excluded in cases of recurrent non-immune hydrops with no obvious aetiology following routine investigations.

Airway edema, stenosis, obstruction and even asphyxia are easy to occur in patients with extensive burn, deep burn of head, face, and neck area, inhalation injuries, etc., which threaten life. Timely tracheotomy and intubation is an important treatment measure, but lack of knowledge and improper handling in some hospitals resulted in airway obstruction. The technique of percutaneous tracheotomy and intubation provides convenience for emergency treatment of critical burns and mass burn. The Burn and Trauma Branch of Chinese Geriatrics Society organized some experts in China to discuss the indications, timing, methods, extubation, and precautions of tracheotomy and intubation for burn patients.
