Gout is the most common inflammatory arthritis among Filipinos, characterized by hyperuricemia leading to mono- sodium urate crystal deposition and an ensuing inflammatory response. Though typically a disorder of middle- aged and older adults, tophaceous gout presenting before the age of 30 is rare and suggests aggressive disease progression. Allopurinol, a first-line urate-lowering therapy, is generally effective but may cause rare, potentially life-threatening adverse reactions such as allopurinol hypersensitivity syndrome (AHS). Febuxostat, a non-purine xanthine oxidase inhibitor, is an alternative for patients intolerant to allopurinol. Although hypersensitivity reactions to febuxostat are extremely rare, isolated case reports document their occurrence in both patients with prior AHS and in allopurinol-naïve individuals. Hypersensitivity to both agents is exceedingly uncommon and presents a major therapeutic challenge. In such cases, febuxostat desensitization, conducted in collaboration with allergy specialists, may permit a viable solution to safely reintroduce urate-lowering therapy and prevent further disease progression. This case report describes a patient with young-onset, tophaceous gout who developed severe hypersensitivity reactions to both allopurinol and febuxostat — an unusual and challenging therapeutic dilemma. The case highlights the need for individualized management strategies, including the consideration of drug desensitization, in patients with limited urate-lowering options.

BACKGROUND AND OBJECTIVE

Barangay Health Workers (BHW) are a crucial part of the local health system. Health services at the barangay level are heavily dependent on BHWs. However, despite their significant role in the local health system, support has been minimal and not commensurate with their contributions. The study aimed to identify the perceived external and internal factors that affect the performance of BHWs.

METHODS

The study identified the BHW-perceived external and internal factors affecting performance, through mixed quantitative and qualitative methods. A self-administered questionnaire with a 4-point Likert scale that will assess the factors was given to 561 BHWs from five different upland municipalities of Cavite. A focus group discussion using open-ended questions was conducted to gain an in-depth understanding of their experiences. Emerging themes were reported into narratives.

RESULTS

BHWs maintained a strong level of participation at required health activities, but more than half were often late, owing to their volunteer status and external responsibilities. They were perceived to have a high sense of duty reflected by punctual submission of reports and confidence in delivering health services. Job satisfaction emerged as a substantial motivator while burnout was not a significant demotivator. Leadership and support from local government and health program management were perceived positively by most BHWs. Service delivery confidence was high among BHWs as reflected in their capability to provide expected services. BHWs perceived that challenges were present in terms of the adequacy of medicines and supplies, and on data transmission, although half were generally satisfied with the organization of health records. Human resources were perceived to be sufficient. Financial aspects showed that while most BHWs do not contribute personally to patient care, a significant minority shell out resources for patients, reflecting financial strains within the health system. The study also revealed the varying motivations for volunteering, including community service, staff shortages, knowledge acquisition, and additional income.

CONCLUSION

External and internal factors affect the performance of BHWs at the local level. These were related to current health systems, political climate, personal household duties, and financial status. Despite facing these challenges, the BHWs showed commendable involvement in local health programs. BHWs remained motivated through training opportunities and positive community feedback but were hindered by a lack of health science knowledge and the need for supplementary income.

BACKGROUND AND OBJECTIVE

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the causative agent of COVID-19 has significantly challenged the public health landscape in late 2019. After almost 3 years of the first ever SARS-CoV-2 case, the World Health Organization (WHO) declared the end of this global health emergency in May 2023. Although, despite the subsequent drop of COVID-19 cases, the SARS-CoV-2 infection still exhibited multiple waves of infection, primarily attributed to the appearance of new variants. Five of these variants have been classified as Variants of Concern (VOC): Alpha, Beta, Gamma, Delta, and the most recent, Omicron. Therefore, the development of methods for the timely and accurate detection of viral variants remains fundamental, ensuring an ongoing and effective response to the disease. This study aims to evaluate the feasibility of the application of an in-house approach in genomic surveillance for the detection of SARS-CoV-2 variants using in silico designed primers.

METHODS

The primers used for the study were particularly designed based on conserved regions of certain genes in the virus, targeting distinct mutations found in known variants of SARS-CoV-2. Viral RNA extracts from nasopharyngeal samples (n=14) were subjected to quantitative and qualitative tests (Nanodrop and AGE). Selected samples were then analyzed by RT-PCR and amplicons were submitted for sequencing. Sequence alignment analysis was carried out to identify the prevailing COVID-19 variant present in the sample population.

RESULTS

The study findings demonstrated that the in-house method was able to successfully amplify conserved sequences (spike, envelope, membrane, ORF1ab) and enabled identification of the circulating SARS-CoV-2 variant among the samples. Majority of the samples were identified as Omicron variant. Three out of four designed primers effectively bound into the conserved sequence of target genes present in the sample, revealing the specific SARSCoV-2 variant. The detected mutations characterized for Omicron found in the identified lineages included K417N, S477N, and P681H which were also identified as mutations of interest. Furthermore, identification of the B.1.448 lineage which was not classified in any known variant also provided the potential of the developed in-house method in detecting unknown variants of COVID-19.

CONCLUSION

Among the five VOCs, Omicron is the most prevalent and dominant variant. The in-house direct PCR product sequencing surveillance (DPPSS) method provided an alternative platform for SAR-CoV-2 variant analysis which is accessible and affordable than the conventional diagnostic surveillance methods and the whole genome sequencing. Further evaluation and improvements on the oligonucleotide primers may offer significant contribution to the development of a specific and direct PCRbased detection of new emerging COVID-19 variants.

BACKGROUND

Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by inflammatory arthritis and extra-articular involvement. Comorbidities are highly prevalent in patients with RA, in particular cardiovascular disease (CVD), which is responsible for over 50% of premature deaths. This study aimed to describe cardiovascular diseases and their risk factors among patients with rheumatoid arthritis in the Philippine General Hospital (PGH).

OBJECTIVE

To describe cardiovascular (CV) diseases and their risk factors among patients with rheumatoid arthritis.

METHODS

A retrospective descriptive cross-sectional study was done in the University of the Philippines – Philippine General Hospital (UP-PGH) inpatient and outpatient services. The study included patients 18 years old and above diagnosed with RA and fulfills the 1987 American College of Rheumatology or 2010 American College of Rheumatology-European League Against Rheumatism (ACR/EULAR) classification criteria with no overlap features with other autoimmune connective tissue diseases and with complete records of the information required for the study from January 2019-December 2022. The primary outcomes of interest were the prevalence of CV diseases and CV risk factors. Descriptive statistics were used to summarize the data.

RESULTS

There were 123 patients in the study, 93.4% outpatients, and 95.1% females, with a mean age and disease duration of 51.3 and 9.8 years, respectively. Disease activity was moderate in 35% and high in 9.7%, based on disease activity score (DAS 28) or clinical disease activity index (CDAI) scores. Methotrexate (54%) was the most commonly used conventional synthetic disease-modifying antirheumatic drug (csDMARD). Glucocorticoid use was observed in 51.2%. None of the patients were receiving a biologic DMARD. There were 24 (19.5%) patients with CV diseases, namely myocardial infarction, heart failure, and stroke. There were 87 (70%) patients with at least one CV risk factor and 62 (50.4%) with multiple risk factors. The risk factors identified were: dyslipidemia (43.1%), hypertension (40.7%), elevated body mass index (35.7%), and diabetes mellitus (15.4%). There were f ive deaths in the hospitalized patients (4%), one due to a myocardial infarction.

CONCLUSION

The majority (70%) in our cohort had at least one CV risk factor, 19.5% had an identified CV disease, and one died from a myocardial infarction. Dyslipidemia was the most common CV risk factor. The high proportion of patients with CV disease and CV risk factors highlights the need to add the screening and management of CV diseases and risk factors as a priority among patients with rheumatoid arthritis.

INTRODUCTION

Acute coronary syndrome (ACS) and end-stage renal disease (ESRD) are both prevalent globally. The diagnosis and management of ACS in ESRD is difficult because the interplay of cardiovascular and renal disease is complicated. The guidelines for ACS may not be applicable to the ESRD population because the trials from which these are drawn mostly excluded ESRD patients.

OBJECTIVE

To determine the clinical profile and outcomes of CKD patients on dialysis admitted for ACS in the Philippine General Hospital (PGH).

METHODS

We did a retrospective cohort study and employed a retrospective review of electronic medical records among ESRD patients presenting with ACS in PGH from May 2021 to November 2023. The collected data was analyzed using univariate and bivariate statistics using PRISM software.

RESULTS

A total of 48 patients with ESRD were admitted for ACS in this study – 8 with STEMI and 40 with NSTEMI. The mean age was 61 years old and 33 (68.8%) were male. Among those with STEMI, six (75%) presented with Kilip II or more. While among those with NSTEMI, 17 (42.5%) had a GRACE score >140 and 27 (67.5%) had an NSTEMI TIMI risk score >2. On average, the patients were on hemodialysis for 31 months prior to admission. The most common comorbidities were hypertension (91.7%) and heart failure (83.3%). On admission, 18 (37.5%) presented with SBP >160, 7 (14.6%) patients presented with shock, and 4 (8.3%) patients presented with cardiac arrest. 38 (79.2%) patients had anemia on admission. 21 (43.8%) patients had left ventricular hypertrophy on electrocardiogram while 34 (70.8%) patients had cardiomegaly on chest radiography. The average left ventricular ejection fraction on echocardiogram was 46% and 27 (90%) patients had segmental wall motion abnormalities. The most common angiographic finding was 3-vessel coronary artery disease seen in 50% of patients. Almost all patients received dualantiplatelet therapy, high dose statin, and beta-blocker. The mortality rate was high at 43.8% with cardiovascular causes being the most common cause of death.

CONCLUSION

This study demonstrates the high mortality rate among patients with ESRD presenting with ACS. Our study portrays that patients with ESRD present with higher risk features including abnormalities in vital signs, laboratories, imaging, high prognostications score, and high in-hospital morbidity.

Knee pain is a common clinical complaint with a broad differential diagnosis. In critically ill patients, acute monoarticular pain and swelling typically raise concern for septic arthritis. However, alternative etiologies such as crystal-induced arthritis, trauma, and hemarthrosis must also be considered.

This report presents a rare case of spontaneous hemarthrosis in a patient receiving prophylactic enoxaparin. Although uncommon, spontaneous hemarthrosis is a significant complication of anticoagulation therapy, particularly with low molecular weight heparins (LMWH) like enoxaparin.

Background: One-third of people with epilepsy have drug-resistant epilepsy, making surgical treatment necessary. Comprehensive pre-surgical evaluations, including long-term video-electroencephalographic (VEEG) monitoring, magnetic resonance imaging (MRI), and neuropsychological testing, are essential components of epilepsy presurgical evaluation. The Epilepsy Center at the Mongolian-Japanese Hospital of MNUMS was established in September 2022 and introduced long-term video-EEG monitoring in May 2023. This marked the first time in Mongolia that comprehensive evaluation for epilepsy surgery became available. Aim: To evaluate the role and outcomes of long-term video-EEG monitoring in the pre-surgical assessment of epilepsy patients Materials and Methods: A prospective cohort study was conducted at the Epilepsy Center of the Mongolian-Japanese Hospital from May 2023 to March 2025. Patients who underwent VEEG and comprehensive pre-surgical evaluation were included. Data included demographic information, seizure history, imaging findings, and neurophysiological assessments (routine, sleep-deprived, and long-term video EEG). Patients were divided into two groups based on whether they met criteria for epilepsy surgery, and surgical outcomes were compared between these groups. Results: A total of 297 patients (104 children and 193 adults) participated in the study. Of these, 96 (32%) were diagnosed with temporal lobe epilepsy and underwent pre-surgical evaluation. The mean age of this group was 33±9.2 years; male-to-female ratio was 1:1. Age of seizure onset was 20±10.9 years, and the mean duration of epilepsy was 14.8±10.3 years. Etiologies included meningitis (21.7%), febrile seizures (15.2%), birth complications (12.5%), and traumatic brain injury (12.5%). The average duration of VEEG monitoring was 1.45±0.68 days, during which 161 seizures were recorded (average 2.64 per patient). No seizures were captured in 35 patients. Among the 96 patients, 29 met the criteria for surgical intervention, and 11 underwent temporal lobe epilepsy surgery. Surgical outcomes were significantly better compared to the non-surgical group (p<0.05). Conclusion Long-term video-EEG monitoring plays a critical role in precisely localizing the epileptogenic zone, identifying seizure types, establishing differential diagnoses, and optimizing surgical candidacy. It is confirmed as an essential diagnostic tool in the pre-surgical evaluation for epilepsy surgery.

Complete androgen insensitivity syndrome (CAIS), also known as Morris syndrome, is a rare X-linked recessive disorder characterized by a 46XY karyotype and a female external phenotype. We present the case of a 32-year-old patient who presented to Unimed International Hospital in 2024 with primary amenorrhea, infertility, and chronic pelvic pain. Clinical examination, imaging, and laboratory investigations led to the diagnosis of CAIS. Laparoscopic surgery was performed to remove bilateral gonadal structures and a cystic mass on the left side. Histopathological analysis revealed testicular tissue and a serous cystadenoma originating from the left mesonephric remnant. Following gonadectomy, hormone replacement therapy was initiated, resulting in stabilization of hormone levels. This rare case highlights the possibility of mesonephric remnant-derived cystadenoma in CAIS and underscores the diagnostic value of cytogenetic and histological evaluations, especially in distinguishing between ovarian and testicular tissue when imaging findings are inconclusive.

Background: Cancer incidence and mortality are steadily increasing both globally and in Mongolia. As these rates rise, traditional Mongolian medicine has long utilized herbal formulas for the treatment of gastric and esophageal cancers and precancerous conditions. One such formulation—Hot Natured 3 Herbs (HN3H)—comprises three species from the Ranunculaceae family: Atragene sibirica L., Ranunculus repens L., and Pulsatilla bungeana L.. However, scientific validation of its anti-tumor effects is essential. This study aimed to investigate the effect of HN3H in a tumor-induced animal model. Aim: To identify the biologically active compounds of HN3H and evaluate their effect in an experimentally induced tumor model in animals. Materials and Methods: The three herbs comprising HN3H—Atragene sibirica L., Ranunculus repens L., and Pulsatilla bungeana L.—were collected during their flowering stage (May–June) in Khishig-Undur, Bulgan province, and dried according to official procedures. Extraction was carried out by maceration in 96% ethanol at a 1:10 ratio. The concentrated extract was suspended in water (1:1) and successively fractionated with dichloromethane, ethyl acetate, butanol, chloroform, and n-hexane. The study was approved by the Research Ethics Committee of the Mongolian National University of Medical Sciences (Protocol №2020/03-04). A colorectal cancer model was established by subcutaneous injection of MC-38 cells (Kerafast, USA) into C57BL/6 mice. Immunohistochemistry was performed using CK20, CDX2, Ki67, and p53 antibodies at 1:100 and 1:200 dilutions. Results: The ethanol extract of HN3H contained 2.98±0.04% total phenolics and 2.16±0.05% total flavonoids. Body weight and tumor volume were measured daily with three repetitions. All groups showed a time-dependent increase in body weight. Mice in groups 1A and 1B received ethanol extract at 50 and 100 mg/kg doses; groups 2A and 2B received dichloromethane extract at the same doses. The negative control group was administered 0.5 mg/kg PBS orally, while the positive control group received intraperitoneal injections of 5-fluorouracil (5FU) at 10 mg/kg twice a week. Tumor growth increased in a time-dependent manner across groups. Compared to the negative control, tumor volumes in four treatment groups showed statistically significant reduction (p˂0.05), while no significant difference was observed when compared to the positive control (p=0.08). Histological analysis revealed necrosis in all groups, with variation in extent. Conclusion The ethanol extract of HN3H exhibited moderate levels of phenolic compounds and a high concentration of flavonoids. HN3H extract inhibited tumor progression and activated lymphocyte-predominant inflammation in tumor tissues, indicating potential anti-tumor activity (p˂0.05).
