INTRODUCTION: Radiofrequency ablation (RFA) avoids the complications of general anaesthesia, reduces length of hospitalisation and reduces morbidity from surgery. As such, it is a strong alternative treatment for patients with comorbidities who are not surgical candidates. However, to our knowledge, there have only been 1 systematic review and 3 combined systematic review and meta-analyses on this topic to date. This systematic review and meta-analysis seeks to evaluate the efficacy and safety of RFA in the treatment of papillary thyroid carcinoma (PTC) with longer follow-up durations. METHOD: PubMed, Embase and Cochrane databases were searched for relevant studies published from 1990 to 2021; 13 studies with a total of 1366 patients were included. The Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines and Sandelowski et al.'s approach1 to "negotiated consensual validation" were used to achieve consensus on the final list of articles to be included. All authors then assessed each study using a rating scheme modified from the Oxford Centre for Evidence-Based Medicine. RESULTS: Pooled volume reduction rates (VRRs) from 1 to 48 months after RFA, complete disappearance rates (CDR) and complications were assessed. Pooled mean VRRs were 96.59 (95% confidence interval [CI] 91.05-102.13, I2=0%) at 12 months2-6 and 99.31 (95% CI 93.74-104.88, I2=not applicable) at 48 months.2,5 Five studies showed an eventual CDR of 100%.2,4,7-9 No life-threatening complications were recorded. The most common complications included pain, transient voice hoarseness, fever and less commonly, first-degree burn. CONCLUSION RFA may be an effective and safe alternative to treating PTC. Larger clinical trials with longer follow-up are needed to further evaluate the effectiveness of RFA in treating PTC.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration. METHOD: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded. RESULTS: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations. CONCLUSION The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

Objectives: Perception about Physical and Rehabilitation Medicine provides information about awareness on identifying disabilities and managing their impact on activities of daily living; however, misconceptions about the field continue to exist among both students and physicians. This study aims to describe the perceptions of clinical clerks and interns towards the practice and role of Rehabilitation Medicine in management of patients. Methods: This is a descriptive cross-sectional study. Students from the Learning Unit 6 and 7 of UP College of Medicine answered adapted online survey forms from a previous study and participated in online focus group discussions. Qualitative data were used to infer the perception of medical students towards the specialty. The effect of the respondent’s profile, background and affiliation on their knowledge, attitudes and perceptions were analyzed using One-Way ANOVA (α = 0.05). Qualitative data were analyzed using thematic analysis. Results: Learning Unit 6 and 7 students were found to have a perceived broad level of knowledge with regards the specialty. The students associated the specialty with focus on holistic care, quality of life, interdisciplinary collaboration, and diversity of cases managed. No statistically significant differences were found between the perception among: 1) Learning Unit 6 and 7, 2) those with or without a previous encounter with the specialty, 3) allied medical and non-allied medical undergraduate courses in terms of: a) confidence in the knowledge (p = 0.489), b) familiarity with conditions managed (p = 0.93) and c) interest towards the specialty (p = 0.693). The Organ System Integrated (OSI) curriculum, which promotes horizontal and vertical integration of concepts, provided a wide understanding of the basic concepts related to physiatry. The students’ responses suggest a positive attitude towards Physical and Rehabilitation Medicine, as measured in their level of interest about knowing more regarding the specialty. Most common perceptions were that the specialty was multidisciplinary and holistic. However, the respondents’ perceptions regarding the roles of the Rehabilitation team were limited. Conclusion Learning unit level 6 and 7 students had a broad understanding of the practice and scope of the Physical and Rehabilitation Medicine specialty. Future researches can include other medical students in all year levels, including Learning Units 3, 4 and 5 of UPCM, to observe the development of their perceptions about the specialty throughout medical school.

Objective: Bariatric surgery effectively treats non-alcoholic fatty liver disease (NAFLD). The glutamate-serine-glycine (GSG) index has emerged as a non-invasive diagnostic marker for NAFLD, but its ability to monitor treatment response remains unclear. This study investigates the GSG index's ability to monitor NAFLD's response to bariatric surgery. Methodology: Ten NAFLD participants were studied at baseline and 6 months post-bariatric surgery. Blood samples were collected for serum biomarkers and metabolomic profiling. Hepatic steatosis [proton density fat fraction (PDFF)] and fibroinflammation (cT1) were quantified with multiparametric magnetic resonance imaging (mpMRI), and hepatic stiffness with magnetic resonance elastography (MRE). Amino acids and acylcarnitines were measured with mass spectrometry. Statistical analyses included paired Student’s t-test, Wilcoxon-signed rank test, and Pearson’s correlation. Results: Eight participants provided complete data. At baseline, all had hepatic steatosis (BMI 39.3 ± 5.6 kg/m2, PDFF ≥ 5%). Post-surgery reductions in PDFF (from 12.4 ± 6.7% to 6.2 ± 2.8%, p = 0.013) and cT1 (from 823.3 ± 85.4ms to 757.5 ± 41.6ms, p = 0.039) were significant, along with the GSG index (from 0.272 ± 0.03 to 0.157 ± 0.05, p = 0.001). Conclusion The GSG index can potentially be developed as a marker for monitoring the response of patients with NAFLD to bariatric surgery.

Musculoskeletal conditions are among the leading causes of consultations in Rehabilitation Medicine. A fellowship program in Musculoskeletal Rehabilitation Medicine was proposed to enrich physiatrists’ knowledge and skills in evaluating and managing musculoskeletal conditions. In this paper, we shared the process of developing the curriculum of the fellowship program, which was proposed to and eventually approved by the Postgraduate Institute of Medicine, College of Medicine, University of the Philippines Manila. A core group of consultants, considered as experienced clinicians and educators in Musculoskeletal Rehabilitation Medicine in the study institution, designed the program from the scope of training to learning competencies, outcomes, and assessment methods. To our knowledge, developing the fellowship program in this constantly evolving area in Rehabilitation Medicine is the first of its kind in the Philippines and a milestone in the history of postgraduate education in the longest-running training program for aspiring physiatrists.

INTRODUCTION: We aimed to assess the attitudes and learner needs of radiology residents and faculty radiologists regarding artificial intelligence (AI) and machine learning (ML) in radiology. METHODS: A web-based questionnaire, designed using SurveyMonkey, was sent out to residents and faculty radiologists in all three radiology residency programmes in Singapore. The questionnaire comprised four sections and aimed to evaluate respondents' current experience, attempts at self-learning, perceptions of career prospects and expectations of an AI/ML curriculum in their residency programme. Respondents' anonymity was ensured. RESULTS: A total of 125 respondents (86 male, 39 female; 70 residents, 55 faculty radiologists) completed the questionnaire. The majority agreed that AI/ML will drastically change radiology practice (88.8%) and makes radiology more exciting (76.0%), and most would still choose to specialise in radiology if given a choice (80.0%). 64.8% viewed themselves as novices in their understanding of AI/ML, 76.0% planned to further advance their AI/ML knowledge and 67.2% were keen to get involved in an AI/ML research project. An overwhelming majority (84.8%) believed that AI/ML knowledge should be taught during residency, and most opined that this was as important as imaging physics and clinical skills/knowledge curricula (80.0% and 72.8%, respectively). More than half thought that their residency programme had not adequately implemented AI/ML teaching (59.2%). In subgroup analyses, male and tech-savvy respondents were more involved in AI/ML activities, leading to better technical understanding. CONCLUSION A growing optimism towards radiology undergoing technological transformation and AI/ML implementation has led to a strong demand for an AI/ML curriculum in residency education.

Leiomyoma of the urinary bladder is not often encountered, occurring in only 0.43% of all bladder tumors. Among the known cases, patients usually present with obstructive symptoms, irritative symptoms or hematuria. This is a rare case of a 50-year-old male who was incidentally diagnosed to have a bladder mass. After cystoscopy, an open partial cystectomy was done with complete resection of the bladder mass. Final histopathology and immunochemical stains confirmed the diagnosis of leiomyoma of the urinary bladder.
