INTRODUCTIONThere are growing concerns that the use of proton pump inhibitors (PPIs) may be inappropriate in instances that do not conform to evidence-based indications. This point-prevalence study aimed to investigate the frequency, indications and appropriateness of use of PPIs in hospitalised patients on a randomly chosen day.

METHODSOn a randomly chosen day, all inpatients were documented, and those on any form of PPIs on that day were determined. Indications for maintaining these patients on PPIs were obtained from the electronic medical records, which were then recorded and cross-referenced against a list of accepted indications adapted from the US Food and Drug Administration (FDA)-approved list.

RESULTSIn all, 1,025 inpatients were documented. Of the 477 (46.5%) inpatients using PPIs, only 219 (45.9%) fulfilled the FDA-approved indications, while the majority (n = 258, 54.1%) did not. Overall, PPIs were not strictly indicated for use in 206 (43.2%) inpatients, according to FDA criteria. Of the 477 inpatients on PPIs, 52 (10.9%) had borderline indications based on expert consensus/guidelines other than FDA criteria.

CONCLUSIONAlthough the use of PPIs is prevalent in hospitals, less than half of the hospitalised patients using PPIs in our study had evidence-based indications that supported such use. The overuse of PPIs has a negative impact on healthcare costs and may lead to adverse effects. Steps to curb the inappropriate use of PPIs should address factors such as indications for the initiation of PPIs, and reassessment of the need for ongoing PPI use in inpatients upon discharge and during outpatient reviews.

INTRODUCTIONThe survival and epidemiology of small-cell lung cancer (SCLC) in Singapore has not been described. We aim to present the characteristics as well as determine the survival outcome and important prognostic factors for SCLC patients.

MATERIALS AND METHODSA retrospective analysis of SCLC patients diagnosed from 1999 to 2002 was conducted at the Outram campus, Singapore. Clinical characteristics and treatment data were obtained from case records and survival data were checked with the registry of births and deaths on 30 May 2005.

RESULTSOne hundred and eleven patients were analysed. There were 38 (34.2%) limited-disease (LD) patients and 73 (65.8%) extensive-disease (ED) patients. The majority were current or former smokers (94.7% among LD and 94.5% among ED). More patients with LD had good performance status (92% versus 63%, P = 0.0003) and were treated with combined chemotherapy and radiotherapy (82% versus 48%, P = 0.012). The median survival time of LD patients treated with curative chemoradiotherapy was 14.2 months (95% CI, 10.96 to 17.44). Those given prophylactic cranial irradiation had a median survival time of 16.9 months (95% CI, 11.83 to 21.97). For ED patients, the median survival time was 8.17 months (95%CI, 5.44 to 10.89). None of the factors analysed were significant prognostic factors for LD patients while performance status and type of treatment given were significant among ED patients.

CONCLUSIONSWe found that the characteristics and survival of SCLC patients in Singapore are fairly similar to that of other countries.

INTRODUCTIONIntravenous tissue plasminogen activator (tPA) within 3 hours of stroke onset is a licensed proven therapy for ischaemic stroke, with recent trial data showing benefit up to 4.5 hours. We previously published in this journal data of a survey conducted in 2004 showing only 9% of ischaemic stroke patients presenting to the Singapore General Hospital (SGH) arrived within 2 hours of onset. We aimed to determine whether the problem of delayed hospital arrival persists in 2009 and to establish the impact of widening the time window for intravenous tPA to 4.5 hours.

MATERIALS AND METHODSWe prospectively surveyed consecutive ischaemic stroke patients admitted to the SGH from 9th March to 30th April 2009. Patients and/or relatives were interviewed with a standardised form similar to the 2004 survey.

RESULTSAmong the 146 ischaemic stroke patients surveyed (median age 67 years, 59% male, median NIHSS score 2), 6% presented to SGH within 2 hours and 15% within 3.5 hours of onset. Median time from stroke onset to hospital arrival was 1245 minutes (20.75 hours). Pre-hospital consultation was significantly associated with hospital arrival after 2 hours from onset. Main reasons cited for delay were not realising the gravity of symptoms (31%) and not recognising them as stroke (27%).

CONCLUSIONDelayed arrival to SGH following acute ischaemic stroke remains a problem in 2009. This confirms the lack of stroke awareness in Singapore and highlights the need for public stroke education. Furthermore, these data confirm that widening the time window for intravenous tPA treatment to 4.5 hours at SGH will increase its utilisation.

INTRODUCTIONIt has been established that combined chemoradiotherapy treatment benefits selected patients with stage III Non Small Cell Lung Cancer (NSCLC). However, locoregional recurrence still poses a problem. The addition of surgery as the third modality may provide a possible solution. We report our experience of using the triple-modality approach in this group of patients.

MATERIALS AND METHODSThis is a retrospective review of 33 patients with stage III NSCLC treated between 1997 and 2005. Patients have good performance status and no significant weight loss. There were 26 males (79 %) with median age of 63 years (range, 43 to 74) and median follow-up of 49 months. Seventy-six percent had Stage IIIA disease. Chemotherapy consisted of paclitaxel at 175 mg/m2 over 3 hours followed by carboplatin at AUC of 5 over 1 hour. Thoracic radiotherapy was given concurrently with the second and third cycles of chemotherapy. All patients received 50 Gray in 25 fractions over 5 weeks.

RESULTSThe main toxicities were grade 3/4 neutropenia (30%), grade 3 infection (15 %) and grade 3 oesophagitis (9%). Twenty-five patients (76%) underwent surgery. Of the 8 who did not undergo surgery, 1 was deemed medically unfit after induction chemoradiotherapy and 4 had progressive disease; 3 declined surgery. Nineteen patients (58 %) had lobectomy and 6 had pneumonectomy. The median overall survival was 29.9 months and 12 patients are still in remission.

CONCLUSIONThe use of the triplemodality approach is feasible, with an acceptable tolerability and resectability rate in this group of patients.
