The burn center in our hospital is a national and regional (Southeast Asia) center. Of all admissions, 10% are related to blast explosions, and 8% due to chemical burns. In the acute burn management protocol of Singapore General Hospital, early surgical debridement is advocated for all acute partial-thickness burns. The aim of early surgical debridement is to remove all debris and unhealthy tissue, preventing wound infection and thereby expediting wound healing. In chemical burns, there can be stubborn eschars that are resistant to traditional debridement. We would like to present a novel technique using the diathermy scratch pad as a cheap and efficient tool for the dual purpose of surgical debridement and dermabrasion.

Objectives: To determine the knowledge, attitude, and practices (KAP) on rabies prevention and control among primary care providers of children 0-18 years old. Methodology: This is an analytical cross-sectional study conducted among primary care providers of children 0- 18-years old in Barangay Sambag I, Cebu City, Philippines. A questionnaire to determine the KAP on rabies prevention and control, originally developed by Lañada et al., was modified and contextualized to the local setting. Respondents with at least 75% correct answers per domain were considered to have good overall knowledge, attitude, and practices. Furthermore, each question under the above domains was analyzed separately to determine any gaps in KAP. Results were recorded as frequencies and percentages. The association of KAP to one another and the respondents’ profiles were analyzed using Chi-square test with a level of significance of 0.05. Results: Among 285 respondents, 59.3% had poor knowledge, 35.8% had wrong practices, and 21.8% had negative attitude on rabies prevention and control. We found that 92.6% did not know that rabies is incurable. As to practices, performing “tandok” (42.5%), or the act of removal of rabies from a wound by using an animal horn, and applying herbal medicines (34%) were still done. Use of dog restraint (44.6%) and euthanasia (40%) weren’t favorable to study participants. Surprisingly, non-dog owners had good knowledge and positive attitude than dog owners. Conclusion Our study showed that majority of the study population had poor knowledge on rabies prevention and control, on disease transmission, and on the incurability of rabies. While majority had a positive attitude and correct practices, the unacceptability on the use of a dog restraint and euthanasia, especially among dog owners, were still evident.

BACKGROUNDHuman adenoviruses (HAdVs) can cause a variety of human illnesses, with associated temporal and geographic changes in disease incidence. We report the emergence of an outbreak of HAdV infections in Singapore, presumably caused by a change of the predominating type to HAdV-7. We examined the clinical features of children admitted with HAdV infection to 1 institution and the risk factors for severe infection.

MATERIALS AND METHODSThis is a retrospective case-control study of all HAdV-infected children admitted during weeks 1 to 19 in 2013, as identified from laboratory records. A descriptive retrospective analysis of epidemiology, clinical data and the outcome of these children was also performed. Patients with severe infections were defined as cases, those with non-severe infections as controls, and the 2 groups were compared to find possible independent risk factors.

RESULTSEighty-five patients with HAdV infection were studied, including 11 (12.9%) cases and 74 (87.1%) controls. Binary logistic regression showed that cases were more likely to be <2 years old (adjusted OR 10.6, 95% CI, 1.8 to 63.2) and to have significant comorbidities (adjusted OR 19.9, 95% CI, 3.4 to 116.1) compared to controls. The predominant type in 2013 was HAdV-7, which differed from 2011 and 2012, when HAdV-3 was more common. There was a trend towards pneumonia being more common in patients infected with HAdV-7 than in patients infected with other types, although this did not reach statistical significance (OR 2.8, 95% CI, 0.9 to 8.7).

CONCLUSIONThe emergence of HAdV-7 in a population where other HAdV types had circulated previously may have caused the outbreak in Singapore, and this was associated with more serious infections in children. Young age (<2 years) and significant comorbidities were associated with more severe HAdV infection.

INTRODUCTION: Laparoscopic colorectal surgery is increasingly performed worldwide due to its multiple advantages over traditional open surgery. In the surgical treatment of right-sided colonic tumours, the latest technique is laparoscopic right hemicolectomy with complete mesocolic excision (lapCME), which aims to lower the rate of local recurrence and maximise survival as compared to standard laparoscopic right hemicolectomy (lapS). METHODS: We conducted a retrospective analysis of our initial experience with lapCME in Singapore General Hospital between 2012 and 2015. All procedures were performed by a single surgeon. RESULTS: Nine patients underwent lapCME and 16 patients underwent lapS. Indication for lapCME was cancer in the right colon. None of the patients required conversion to open surgery, and all were discharged well. The number of lymph nodes resected in the lapCME group was significantly greater than in the lapS group (29 ± 15 vs. 19 ± 6; p = 0.02) during the study period, and the mean operation time was significantly longer for lapCME (237 ± 50 minutes vs. 156 ± 46 minutes; p = 0.0005). There were no statistically significant differences in terms of demographics, tumour stage, time taken for bowel to open postoperatively, time taken for patient to resume a solid diet postoperatively and length of hospital stay. Two patients who underwent lapS were re-admitted for intra-abdominal collections - one patient required radiology-guided drainage, while the other patient was managed conservatively. CONCLUSION Our initial experience with lapCME confirms the feasibility and safety of the procedure.

Purpose: In patients with acute left-sided colonic obstruction, stenting can convert an emergency operation into a semi-elective procedure. However, its use continues to be debated. We performed a cost-effective analysis using our institution’s experiences. Methods: Endoscopic, surgical, and financial details were prospectively collected for patients who presented with acute colonic obstruction and underwent stenting between 2019 and 2022. Outcomes were defined as technical/clinical success and successful surgical resection. The financial cost of stenting was compared with the expected cost without stenting. Results: Forty patients were included, with 29 undergoing definitive resection. The most common pathology was primary colon cancer (27 patients, 93%). Endoscopic stenting had high technical (90%) and clinical (83%) success rates, with low rates of complications such as perforation (2 patients, 7%) and migration (0 patients, 0%). As a bridge to surgery, the median procedure time was 226 minutes and the surgical outcomes also showed a low rate of complications (3 patients, 11%), such as anastomotic leakage (0 patients, 0%), intraabdominal abscesses (2 patients, 7%), and 30-day postoperative mortality (0 patients, 0%). The cumulative costs with colonic stenting were $32,900, while the expected costs with emergency surgery, including stoma reversal, were $40,700 (healthcare cost-savings of $7,800 per person). The difference was mainly due to the avoidance of upfront emergency surgery. The incremental cost-effectiveness ratio was 0.81, favoring colonic stenting over upfront emergency surgery. Conclusion Colonic stenting as a bridge to surgery is safe and cost-effective for treating left-sided colonic obstruction with high success rates and low complication rates.
