| 1 | Spectral analysis of bowel sounds in intestinal obstruction using an electronic stethoscope显示文摘AIM: To determine the value of bowel sounds analysis using an electronic stethoscope to support a clinical diagnosis of intestinal obstruction. METHODS: Subjects were patients who presented with a diagnosis of possible intestinal obstruction based on symptoms, signs, and radiological findings. A 3MTH Littmann Model 4100 electronic stethoscope was used in this study. With the patients lying supine, six 8-second recordings of bowel sounds were taken from each patient from the lower abdomen. The recordings were analysed for sound duration, soundto-sound interval, dominant frequency, and peak frequency. Clinical and radiological data were reviewed and the patients were classified as having either acute, subacute, or no bowel obstruction. Comparison of bowel sound characteristics was made between these subgroups of patients. In the presence of an obstruction, the site of obstruction was identified and bowel calibre was also measured to correlate with bowel sounds. RESULTS: A total of 71 patients were studied during the period July 2009 to January 2011. Forty patientshad acute bowel obstruction (27 small bowel obstruction and 13 large bowel obstruction), 11 had subacute bowel obstruction (eight in the small bowel and three in large bowel) and 20 had no bowel obstruction (diagnoses of other conditions were made). Twenty-five patients received surgical intervention (35.2%) during the same admission for acute abdominal conditions. A total of 426 recordings were made and 420 recordings were used for analysis. There was no significant difference in sound-to-sound interval, dominant frequency, and peak frequency among patients with acute bowel obstruction, subacute bowel obstruction, and no bowel obstruction. In acute large bowel obstruction, the sound duration was significantly longer (median 0.81 s vs 0.55 s, P = 0.021) and the dominant frequency was significantly higher (median 440 Hz vs 288 Hz, P = 0.003) when compared to acute small bowel obstruction. No significant difference was seen between acute large bowel obstruction and large bowel pseudoobstruction. For patients with small bowel obstruction, the sound-to-sound interval was significantly longer in those who subsequently underwent surgery compared with those treated non-operatively (median 1.29 s vs 0.63 s, P < 0.001). There was no correlation between bowel calibre and bowel sound characteristics in both acute small bowel obstruction and acute large bowel obstruction. CONCLUSION: Auscultation of bowel sounds is nonspecific for diagnosing bowel obstruction. Differences in sound characteristics between large bowel and small bowel obstruction may help determine the likely site of obstruction. | Siok Siong Ching Yih Kai Tan | 2012 | World Journal of Gastroenterology2012，18，33： | 14 |

| 5 | Prehospital system delay in patients with ST-segment elevation myocardial infarction in Singapore显示文摘BACKGROUND: Timely reperfusion in ST-segment elevation myocardial infarction(STEMI)improves outcomes. System delay is that between first medical contact and reperfusion therapy,comprising prehospital and hospital components. This study aimed to characterize prehospital system delay in Singapore.METHODS: A retrospective chart review was performed for 462 consecutive STEMI patients presenting to a tertiary hospital from December 2006 to April 2008. Patients with cardiac arrest secondarily presented were excluded. For those who received emergency medical services(EMS),ambulance records were reviewed. Time intervals in the hospital were collected prospectively. The patients were divided into two equal groups of high/low prehospital system delay using visual binning technique.RESULTS: Of 462 patients, 76 received EMS and 52 of the 76 patients were analyzed. The median system delay was 125.5 minutes and the median prehospital system delay was 33.5minutes(interquartile range [IQR]=27.0, 42.0). Delay between call-received-by-ambulance and ambulance-dispatched was 2.48 minutes(IQR=1.47, 16.55); between ambulance-dispatch and arrival-at-patient-location was 8.07 minutes(IQR=1.30, 22.13); between arrival-at- and departurefrom-patient-location was 13.12 minutes(IQR=3.12, 32.2); and between leaving-patient-location to ED-registration was 9.90 minutes(IQR=1.62, 32.92). Comparing patients with prehospital system delay of less than 35.5 minutes versus more showed that the median delay between ambulancedispatch and arrival-at-patient-location was shorter(5.75 vs. 9.37 minutes, P<0.01). The median delay between arrival-at-patient-location and leaving-patient-location was also shorter(10.78 vs.14.37 minutes, P<0.01).CONCLUSION: Prehospital system delay in our patients was suboptimal. This is the first attempt at characterizing prehospital system delay in Singapore and forms the basis for improving efficiency of STEMI care. | Andrew Fu Wah Ho Pin Pin Pek Stephanie Fook-Chong Ting Hway Wong Yih Yng Ng Aaron Sung Lung Wong Marcus Eng Hock Ong | 2015 | World Journal of Emergency Medicine2015，6，4： | 6 |
| 6 | Sensitivities of Numerical Model Forecasts of Extreme Cyclone Events显示文摘A global forecast model is used to examine various sensitivities of numerical predictions of three extreme winter storms that occurred near the eastern continental margin of North America: the Ohio Valley blizzard of January 1978, the New England blizzard of February 1978, and the Mid-Atlantic cyclone of February 1979. While medium-resolution simulations capture much of the intensification, the forecasts of the precise timing and intensity levels suffer from various degrees of error. The coastal cyclones show a 5-10 hPa dependence on the western North Atlantic sea surface temperature, which is varied within a range (± 2.5℃) compatible with interannual fluctuations. The associated vertical velocities and precipitation rates show proportionately stronger dependences on the ocean temperature perturbations. The Ohio Valley blizzard, which intensified along a track 700-800 km from the coast, shows little sensitivity to ocean temperature.

| 7 | History and perspectives of induction technology for agarwood production from cultivated Aquilaria in Asia: a review显示文摘Agarwood, the resinous product of Aquilaria spp.(Thymelaeaceae), is highly valued for medicinal and fragrant purposes. Unsustainable forest harvesting contributes to the declining population in the wild, threatening their existence. As a protection effort, cultivation occurred in range countries, mainly in Asia, effectively establishing mass plantations. The success of domesticating Aquilaria relies heavily on technological advancement in agarwood induction, without which the entire thriving industry will collapse. In this paper, we describe efforts since 1929 and current progress and variation in induction as practiced in Asia. The methods include traditional practices and artificial induction via inoculum and chemical inducer, experimented and patented or otherwise. Artificial induction methods are being developed to intensify agarwood production in terms of yield and quality. While traditional methods are commonly applied by rural planters, artificial methods with the use of specific agents/chemicals are seen as more appealing for inducing agarwood, and have a higher demand from entrepreneurs and plantation owners.Several issues related to induction technology faced by stakeholders in agarwood cultivation are presented, such as safety levels, cost, yields, and quality. We conclude by highlighting remaining challenges in induction methods and their associated technologies. | Putra Desa Azren Shiou Yih Lee Diana Emang Rozi Mohamed | 2019 | Journal of Forestry Research2019，30，1： | 4 |
| 8 | Staphylococcal thoracic aortitis complicated by aortic dissection显示文摘BACKGROUND:The diagnosis of aortitis is often delayed as symptoms are largely nonspecific.We report a case of Staphylococcal thoracic aortitis in a 73-year-old Chinese woman complicated by aortic dissection.METHODS:The patient presented with pyrexia of unknown origin,and a contrast enhanced computed tomography aortogram revealed a large thrombus at the anterior aspect of the ascending aorta with two large ulcerations as a result of a chronic type A aortic dissection.A hemiarch replacement with a 28 mm Gleweave Vascutek graft was performed with resuspension of aortic valve commisures.Aortic thrombus cultures were positive for coagulase negative Staphylococcus aureaus,and histology showed chronic dissection of the aorta.RESULTS:The patient was treated with intravenous cefazolin for a 6-week duration and made good progress.CONCLUSIONS:This case highlights Staphylococcal infective aortitis complicated by dissection presenting as fever of unknown origin.Timely diagnosis is essential as progression to catastrophic rupture may occur. | Paul Chun Yih Lim Jean Mui Hua Lee Yeow Leng Chua Stanley Chia1 | 2013 | World Journal of Emergency Medicine2013，4，2： | 3 |

| 14 | Perihepatic nodes detected by point-of-care ultrasound in acute hepatitis and acute-on-chronic liver disease显示文摘AIM: To study the manifestations of perihepatic lymph nodes during the episode of acute hepatitis flare by point-of-care ultrasonography.METHODS: One hundred and seventy-six patients with an episode of acute hepatitis flare(ALT value > 5 × upper normal limit) were enrolled retrospectively. Diagnosis of etiology of the acute hepatitis flare was based on chart records and serological and virological assays. The patients were categorized into two groups(viral origin and non-viral origin) and further defined into ten subgroups according to the etiologies. An ultrasonograpy was performed within 2 h to 72 h(median, 8 h). The maximum size of each noticeable lymph node was measured. Correlation between clinical parameters and nodal manifestations was analyzed RESULTS: Enlarged lymph nodes(width ≥ 5mm)were noticeable in 110(62.5%) patients, mostly in acute on chronic hepatitis B(54.5%). The viral group had a higher prevalence rate(89/110 = 80.9%) and larger nodal size(median, 7 mm) than those of the non-viral group(21/66 = 31.8%; median, 0 mm)(P < 0.001 for both). Meanwhile, there were significant differences in the nodal size between acute and chronic viral groups(P < 0.01), and between acute hepatitis A and non-hepatitis A viral groups(P < 0.001). In logistical regression analysis, the nodal width still showed strong significance in multivariate analysis(P < 0.0001) to stratify the two groups. The area under the curve of ROC was 0.805, with a sensitivity of 80.9%, a specificity of 68.2%, positive predictive value of 80.92%, negative predictive value of 68.18%, and an accuracy of 76.14%. CONCLUSION: Point-of-care ultrasonography to detect perihepatic nodal change is valuable for clarifying the etiologies in an episode of acute hepatitis flare. | I Che Feng Szu Jen Wang Ming Jen Sheu Lok-Beng Koay Ching Yih Lin Chung Han Ho Chi Shu Sun Hsing Tao Kuo | 2015 | World Journal of Gastroenterology2015，21，44： | 2 |
