INRODUCTION
Stroke is one of the top five leading causes of disability in the Philippines. It has a significant impact on the quality of life (QoL) of patients, particularly in the functional and psycho-emotional aspects. Thus, it is important to understand the health-related quality of life in stroke patients (HRQoLISP), which focuses on the clinical impact of the disease and disability. The assessment of a stroke patient’s QoL is prognostically significant as it can predict a patient’s treatment success and survival.
OBJECTIVEThis study aims to translate the HRQoLISP-26 into Filipino and assess its content validity for Filipino adult stroke patients.
METHODOLOGYThe HRQoLISP-26 was translated into Filipino using a forward translation protocol and an expert analyzed the forward translation. Selected expert committee members reviewed the first version to assess for content validity and the questionnaire was modified accordingly. The content validity index (CVI) was used for content validity.
RESULTSMajority of the revisions made were done to improve the semantic and grammatical accuracy of items in the Filipino version of the HRQoLISP-26. Only a few items had no revisions implemented. No revisions were done in the final version of the translated questionnaire as each item had a CVI of 1 indicating that it has good content validity.
CONCLUSIONThe Filipino translated HRQoLISP-26 questionnaire is a validated questionnaire that allows assessment of a stroke survivor’s QoL.

Robotic-assisted pedicle screw placement and full-endoscopic transforaminal lumbar interbody fusion (FE-TLIF) are established minimally invasive spine techniques. Their integration has the potential to combine navigation accuracy with the muscle-preserving advantages of uniportal endoscopy. This technical note describes a hybrid approach using the Mazor X Stealth edition robotic system to enhance workflow, safety, and efficiency during FE-TLIF. A 74-year-old patient with metabolic syndrome presented with severe back and radicular leg pain that was refractory to conservative treatment. Magnetic resonance imaging demonstrated bilateral lateral recess stenosis, disc height loss, and facet arthropathy at L4–5, with dynamic instability observed on flexion-extension radiographs. Preoperative computed tomography imaging was uploaded to the robotic system for trajectory planning. Following registration, the robotic arm guided percutaneous pedicle screw placement via Wiltse incisions. Uniportal endoscopic access enabled hemilaminotomy, facetectomy, discectomy, endplate preparation, and insertion of an expandable L4–5 interbody cage under direct visualization. Robotic guidance facilitated precise screw trajectory placement without repeated fluoroscopic localization, reduced intraoperative radiation exposure, and avoided muscle disruption associated with open approaches. Endoscopic visualization enabled controlled facet resection and preservation of neural elements during cage placement. Postoperative radiographs confirmed appropriate implant positioning. The combined workflow improved surgical ergonomics and minimized tissue trauma while maintaining fusion stability. Robotic-assisted FE-TLIF represents a safe and feasible hybrid minimally invasive surgery technique that enhances pedicle screw accuracy and complements endoscopic fusion. Despite a steep learning curve, this approach may reduce perioperative morbidity, improve procedural efficiency, and enhance postoperative recovery. Further comparative studies are required to evaluate long-term clinical and radiographic outcomes.

Objective:
Spinal stenosis and degenerative spinal disorders are increasingly prevalent and have a substantial impact on quality of life. Surgical decompression, performed using either open microscopic or endoscopic approaches, remains a cornerstone of management for these conditions. This study examines evolving trends in single-level lumbar spinal decompression procedures performed at a tertiary academic hospital in Singapore.
Methods:
A retrospective observational study was conducted involving 588 patients who underwent single-level spinal decompression between 2021 and 2024, including endoscopic spine surgery (ESS; n=364) and microdecompression (n=224). Primary outcome measures were changes in 36-Item Short Form Health Survey (SF-36) and visual analogue scale (VAS) scores at 3 months, 6 months, and 2 years postoperatively. Secondary outcomes included length of hospital stay, reoperation rates, and operative time. Patient demographics, spinal level and pathology characteristics, surgical techniques, and postoperative outcomes were analyzed. Difference-in-differences (DID) analysis was used to compare outcomes between the 2 groups.
Results:
Both groups demonstrated significant postoperative improvements in SF-36 and VAS scores. At 2 years, Short Form Health Survey physical function (SFPF) scores improved in the endoscopic group (mean difference [MD], 18.6; standard deviation [SD], 21.7; p=0.064) and in the open microscopic group (MD, 36.7; SD, 20.9; p=0.007), with a non-significant DID of -18.1 (p=0.155). No DID comparisons across SF-36 domains reached statistical significance. Mean operative time for endoscopic procedures decreased from 249 minutes in 2022 to 145 minutes in 2024, reflecting a procedural learning curve. Surgeons with higher endoscopic caseloads exhibited greater improvements in functional outcomes.
Conclusion
Both endoscopic and open microscopic decompression achieve comparable short- and long-term clinical outcomes. ESS provides similar effectiveness while being associated with shorter recovery periods and reduced hospital stay. Further research is warranted to identify factors contributing to incomplete symptom resolution or the need for revision surgery.

BACKGROUND AND OBJECTIVE
Accurately diagnosing bacterial meningitis and ventriculitis in children is challenging due to nonspecific symptoms and the lack of specificity in conventional CSF parameters. Cerebrospinal fluid (CSF) procalcitonin (PCT) is a promising diagnostic marker but studies on its utility in children are lacking. We aimed to assess the diagnostic value of CSF procalcitonin for bacterial meningitis and ventriculitis in children and establish a clinically relevant cut-off level.
METHODSA total of 131 patients were included in the study, and the CSF PCT levels were measured in two groups. Group 1 comprised of patients with bacterial meningitis and ventriculitis (n=21), while Group 2 consisted of patients with tuberculous meningitis, fungal meningitis, viral encephalitis, autoimmune encephalitis, central nervous system (CNS) leukemia, and non-infectious or inflammatory CNS conditions (n=110).
RESULTSCSF PCT demonstrated an area under the curve of 96.57% in the receiver operating characteristic analysis. With a cut-off of 0.19 ng/mL, it achieved high sensitivity (90.48%) and specificity (91.82%), making it an excellent test for distinguishing between bacterial meningitis and ventriculitis from control diseases.
CONCLUSIONCSF procalcitonin is highly effective in distinguishing pediatric bacterial meningitis and ventriculitis. Especially in clinical scenarios where the conventional laboratory tests are inconclusive, it can complement clinical assessment to diagnose CNS infections accurately and guide prudent antibiotic use.

INTRODUCTION:
Adolescent depression is prevalent, and teen suicide rates are on the rise locally. A systemic review to understand associated risk and protective factors is important to strengthen measures for the prevention and early detection of adolescent depression and suicide in Singapore. This systematic review aims to identify the factors associated with adolescent depression in Singapore.
METHODS:
A systematic search on the following databases was performed on 21 May 2020: PubMed, EMBASE and PsycINFO. Full texts were reviewed for eligibility, and the included studies were appraised for quality using the Newcastle Ottawa Scale. Narrative synthesis of the finalised articles was performed through thematic analysis.
RESULTS:
In total, eight studies were included in this review. The four factors associated with adolescent depression identified were: (1) sociodemographic factors (gender, ethnicity); (2) psychological factors, including childhood maltreatment exposure and psychological constructs (hope, optimism); (3) coexisting chronic medical conditions (asthma); and (4) lifestyle factors (sleep inadequacy, excessive internet use and pathological gaming).
CONCLUSION
The identified factors were largely similar to those reported in the global literature, except for sleep inadequacy along with conspicuously absent factors such as academic stress and strict parenting, which should prompt further research in these areas. Further research should focus on current and prospective interventions to improve mental health literacy, targeting sleep duration, internet use and gaming, and mitigating the risk of depression in patients with chronic disease in the primary care and community setting.

INTRODUCTION:
Radiology plays an integral role in fracture detection in the emergency department (ED). After hours, when there are fewer reporting radiologists, most radiographs are interpreted by ED physicians. A minority of these interpretations may miss diagnoses, which later require the callback of patients for further management. Artificial intelligence (AI) has been viewed as a potential solution to augment the shortage of radiologists after hours. We explored the efficacy of an AI solution in the detection of appendicular and pelvic fractures for adult radiographs performed after hours at a general hospital ED in Singapore, and estimated the potential monetary and non-monetary benefits.
METHODS:
One hundred and fifty anonymised abnormal radiographs were retrospectively collected and fed through an AI fracture detection solution. The radiographs were re-read by two radiologist reviewers and their consensus was established as the reference standard. Cases were stratified based on the concordance between the AI solution and the reviewers' findings. Discordant cases were further analysed based on the nature of the discrepancy into overcall and undercall subgroups. Statistical analysis was performed to evaluate the accuracy, sensitivity and inter-rater reliability of the AI solution.
RESULTS:
Ninety-two examinations were included in the final study radiograph set. The AI solution had a sensitivity of 98.9%, an accuracy of 85.9% and an almost perfect agreement with the reference standard.
CONCLUSION
An AI fracture detection solution has similar sensitivity to human radiologists in the detection of fractures on ED appendicular and pelvic radiographs. Its implementation offers significant potential measurable cost, manpower and time savings.

INTRODUCTION:
Randomised controlled trials (RCTs) have informed guideline recommendations for the management of stable coronary artery disease (CAD). However, the real-world impact of contemporary guidelines and trials on practising physicians in the Asia-Pacific region remains uncertain. We aimed to evaluate the knowledge, attitudes and practices among cardiovascular physicians in the region regarding stable CAD management.
METHOD:
An anonymised cross-sectional electronic survey was administered to cardiovascular practitioners from the Asia Pacific, assessing 3 domains: 1) baseline knowledge on recent trials and society guideline, 2) attitudes towards stable CAD, and 3) case scenarios reflecting management preferences. Correlations among knowledge, attitudes and practice scores were assessed between physicians from developed and developing countries using Pearson correlation.
RESULTS:
Overall, 713 respondents from 21 countries completed the survey. The mean knowledge score was 2.90±1.18 (out of 4), with 37.3% of respondents answering all questions correctly, while 74.6% noted that guidelines have significant impact on their practice. Despite guidelines recommending optimal medical therapy, majority chose revascularisation (range 53.4- 90.6%) as the preferred strategy for the case scenarios. Practitioners from developed regions had higher knowledge scores and lower attitude scores compared to developing regions, while practice scores were similar in both groups. Weakly positive correlations were noted between knowledge, attitude and practice scores.
CONCLUSION
Variations exist in knowledge and attitudes towards guideline recommendations and correspondingly actual clinical practice in the Asia Pacific, with most practitioners choosing an upfront invasive strategy for the treatment of stable CAD. These differences reflect real-world disparities in guideline interpretation and clinical adoption.

BACKGROUND
Hypertension is the most common risk factor for cardiovascular disease in the Philippines. Despite the availability of antihypertensive medications that are effective, safe, and tolerated by Filipino patients, the numbers of uncontrolled hypertensives are still increasing. Several factors play in the poor control of blood pressure, particularly resistant hypertension and hyperactive sympathetic nervous system. Renal denervation therapy is a novel device that has been shown to lower blood pressure in patients with resistant and difficult-to-treat hypertension and is deemed safe in clinical trials. A Philippine Working Group composed of specialists in cardiology, hypertension, vascular surgery, and clinical epidemiology has come up with consensus statements in identifying patients who will benefit from the procedure. Locally, there is a need to have hypertension centers treating uncontrolled and resistant hypertension and offer renal denervation therapy to appropriate Filipino patients.

Objectives:
To compare the vector analysis, visual, and refractive outcomes of femtosecond-assisted laser insitu keratomileusis (LASIK) and small incision lenticule extraction (SMILE) among myopic patients with
moderate myopic astigmatism.
Methods:
This was a single-center, retrospective, cohort study that compared eyes that underwent
femtosecond LASIK or SMILE for the correction of myopia and astigmatism of 0.75 to 3.0 diopters. Vector
analysis and standard graphs for reporting visual and refractive outcomes were utilized for analysis.
Results:
There were 82 femtosecond LASIK-treated eyes and 80 SMILE-treated eyes with similar preoperative
characteristics except for slightly higher mean preoperative sphere refraction in the SMILE group (-4.2±2.4 D
vs -4.9±1.6 D, p=0.03). At 3 months, femtosecond LASIK group had better mean uncorrected distance visual
acuity (UDVA) (LogMAR 0.006±0.06 vs 0.06±0.09, p=0.00) and had more eyes achieving postoperative
UDVA of 20/20 or better (88% versus 56%). Although there were similar postoperative spherical equivalents,
residual astigmatism was higher in the SMILE group (0.11±0.22 D vs 0.32±0.30 D, p=0.00). Vector analyses
showed significantly better outcomes for femtosecond LASIK than for SMILE in terms of difference vector
(DV), index of success (IOS), torque, and flattening index (FI). A trend for undercorrection for higher
astigmatism was seen in both groups that was greater in the SMILE group. Both groups showed high safety
with the majority of eyes showing postoperative corrected distance VA (CDVA) within 1 line of preoperative
CDVA (98.8% versus 91.2%).
Conclusion
Although femtosecond LASIK and SMILE have similar predictability at 3 months, femtosecond
LASIK has relatively better efficacy and superior astigmatic outcomes than SMILE for the correction of
moderate myopic astigmatism.

OBJECTIVE
This study compared the demographics, clinical profile, treatment, and outcomes of retinoblastoma patients seen at medical institutions in the Philippines between two time periods: 2010 to 2015 and 2016 to 2020.
METHODSThis was a multicenter, analytical, cohort study using review of medical charts and databases of retinoblastoma patients seen in 11 medical institutions from 2010 to 2020.
RESULTSThere were 636 patients (821 eyes) included in this study: 330 patients were seen in 2010 to 2015 while 306 in 2016 to 2020. More cases per annum were seen in the latter timeline. The number of patients with unilateral disease was not significantly different between the two time periods (p=0.51). Age at onset of symptom, age at initial consultation, and delay in consult were also not significantly different between the two time periods (p > 0.05). Patients had significantly different distributions of intraocular grades (p < 0.0001) and systemic staging (p < 0.0001) between the two time periods. Enucleation was the most common surgical treatment performed in both timelines. There was significant difference in the status of patients based on the need for systemic chemotherapy (p < 0.01). There was significant difference in outcome between the two time periods, including the proportions of living and deceased patients.
CONCLUSIONThis study compared the most comprehensive data on retinoblastoma patients in the country. There was no improvement in early health seeking behavior based on similar age at initial consult and delay in consult. Enucleation remained the most common treatment mode as opposed to chemotherapy due to similar percentage of patients with unilateral disease, an indication for enucleation rather than chemotherapy.
