Objectives:
This study described the clinical profile of patients with keratoconus at a single tertiary referral hospital.
Methods:
This was a single-center, retrospective, cross-sectional study that reviewed medical records of
patients diagnosed with keratoconus from January 2015 to August 2022. Data on the clinical profile,
intervention, and clinical outcomes were collected from the chart review.
Results:
Forty (40) patients (79 eyes) were included in the study. Majority (98%) had bilateral disease in which
22 (55.5%) were affected asymmetrically. The mean age was 21 years. Most patients (72.5%) were male. Blurring
of vision was the chief complaint in all patients. Atopy was present in 23 patients (57.5%). History of vigorous
eye rubbing was present in 31 (77.5%). The mean interval from onset of symptoms to consult was 46.4 ± 33.38
months. The mean pinhole corrected distance visual acuity was 0.47 ± 0.41 (Snellen equivalent of 20/59). The
average spherical equivalent was -7.48D ± 6.99D. Corneal protrusion on slit-lamp biomicroscopy was seen in
78 eyes (98.7%). Other findings included Fleischer ring (53.2%), Vogt's striae (19.0%), and apical corneal scar
(24.0%). Only one eye (1.3%) had no corneal findings. Thirty-nine eyes (49.3%) were classified as advancedsevere keratoconus. Rigid contact lens was planned for 60 eyes (75.9%). Sixty-two eyes (78.5%) were for
collagen cross-linking. Deep anterior lamellar keratoplasty was planned in 10 eyes (12.7%) and penetrating
keratoplasty in two eyes (2.5%).
Conclusion
Keratoconus at the Philippine General Hospital was most frequently seen in young males and
asymmetrically affects both eyes. Patients consulted relatively late and presented with a more advanced stage of
the disease. History of ocular allergy and eye rubbing were significant risk factors. Improving awareness of this
condition must be emphasized to detect keratoconus earlier.

Malaysian Orthopaedic Journal 2024;18(No.1):60-65
Introduction: To describe the duration of survival among
bone tumour patients with endoprosthesis reconstruction and
to determine frequency of implant failure, revision of
surgery, and amputation after endoprosthesis reconstruction.
Materials and methods: A retrospective cross-sectional
review of all patients with either primary bone tumour or
secondary bone metastases treated with en bloc resection and
endoprosthesis reconstruction from January 2008 to
December 2020.
Results: A total of 35 failures were recorded among the 27
(48.2%) patients with endoprostheses. Some of the patients
suffered from one to three types of modes of failure on
different timelines during the course of the disease. Up to
eight patients suffered from more than one type of failure
throughout the course of the disease. Out of all modes of
failure, local recurrence (type 5 failure) was the most
common, accounting for 25.0% of all failure cases. Four
patients (7.1%) eventually underwent amputation, which
were either due to infection (2 patients) or disease
progression causing local recurrence (2 patients).
Conclusion: The overall result of endoprosthesis
reconstruction performed in our centre was compatible with
other centres around the world. Moreover, limb salvage
surgery should be performed carefully in a selected patient
group to maximise the benefits of surgery.

INTRODUCTION:
The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact in Asia and has placed significant burden on already stretched healthcare systems. We examined the impact of COVID-19 on the safety attitudes among healthcare workers (HCWs), as well as their associated demographic and occupational factors, and measures of burnout, depression and anxiety.
METHODS:
A cross-sectional survey study utilising snowball sampling was performed involving doctors, nurses and allied health professions from 23 hospitals in Singapore, Malaysia, India and Indonesia between 29 May 2020 and 13 July 2020. This survey collated demographic data and workplace conditions and included three validated questionnaires: the Safety Attitudes Questionnaire (SAQ), Oldenburg Burnout Inventory and Hospital Anxiety and Depression Scale. We performed multivariate mixed-model regression to assess independent associations with the SAQ total percentage agree rate (PAR).
RESULTS:
We obtained 3,163 responses. The SAQ total PARs were found to be 35.7%, 15.0%, 51.0% and 3.3% among the respondents from Singapore, Malaysia, India and Indonesia, respectively. Burnout scores were highest among respondents from Indonesia and lowest among respondents from India (70.9%-85.4% vs. 56.3%-63.6%, respectively). Multivariate analyses revealed that meeting burnout and depression thresholds and shifts lasting ≥12 h were significantly associated with lower SAQ total PAR.
CONCLUSION
Addressing the factors contributing to high burnout and depression and placing strict limits on work hours per shift may contribute significantly towards improving safety culture among HCWs and should remain priorities during the pandemic.

Inflammatory bowel disease (IBD), once considered a disease of the Western hemisphere, has emerged as a global disease. As the disease prevalence is on a steady rise, management of IBD has come under the spotlight. 5-Aminosalicylates, corticosteroids, immunosuppressive agents and biologics are the backbone of treatment of IBD. With the advent of biologics and small molecules, the need for surgery and hospitalization has decreased. However, economic viability and acceptability is an important determinant of local prescription patterns. Nearly one-third of the patients in West receive biologics as the first/initial therapy. The scenario is different in developing countries where biologics are used only in a small proportion of patients with IBD. Increased risk of reactivation of tuberculosis and high cost of the therapy are limitations to their use. Thiopurines hence become critical for optimal management of patients with IBD in these regions. However, approximately one-third of patients are intolerant or develop adverse effects with their use. This has led to suboptimal use of thiopurines in clinical practice. This review article discusses the clinical aspects of thiopurine use in patients with IBD with the aim of optimizing their use to full therapeutic potential.

Background:
There is an increasing trend of obesity in the Philippines with approximately 28.8% of adults
considered overweight and 9.6% obese. This is presumably due to a shift in eating patterns towards dining out in restaurants and fast food chains for their convenience. Excess fast food consumption results in diets that are calorie dense yet nutritionally deficient due to their high levels of fat, sugar, and salt leading to increased prevalence of associated diseases such as Type 2 diabetes and cardiovascular diseases.
Objective:
The researchers determined the effect of presenting the caloric information of fast food items on the total calories ordered among college students in private and public higher education institutions in Quezon City.
Methodology:
A double-blind experimental research was performed with 179 students by convenience sampling. The participants were randomly assigned to a control group (without caloric labels) and an experimental group (with caloric labels). An online questionnaire was sent to each subject containing their menu and order form along with questions on their demographical data (age, sex, food allowance, BMI, physical activity).
Results:
Using single linear regression, none of the demographic characteristics were found to be confounding variables. Using multiple linear regression analysis, it was found that the experimental group ordered significantly less calories (p-value = 0.013).
Conclusion
The results of the study conclude that those presented with calorie labels ordered less calories than
the control.

Objective: To determine whether environmental surface contamination with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurred at a provincial hospital in Viet Nam that admitted patients with novel coronavirus disease 2019 (COVID-19) and at the regional reference laboratory responsible for confirmatory testing for SARS-CoV-2 in 2020.
Methods: Environmental samples were collected from patient and staff areas at the hospital and various operational and staff areas at the laboratory. Specimens from frequently touched surfaces in all rooms were collected using a moistened swab rubbed over a 25 cm2 area for each surface. The swabs were immediately transported to the laboratory for testing by real-time reverse transcription polymerase chain reaction (RT-PCR). Throat specimens were collected from staff at both locations and were also tested for SARS-CoV-2 using real-time RT-PCR.
Results: During the sampling period, the laboratory tested 6607 respiratory specimens for SARS-CoV-2 from patients within the region, and the hospital admitted 9 COVID-19 cases. Regular cleaning was conducted at both sites in accordance with infection prevention and control (IPC) practices. All 750 environmental samples (300 laboratory and 450 hospital) and 30 staff specimens were negative for SARS-CoV-2.
Discussion: IPC measures at the facilities may have contributed to the negative results from the environmental samples. Other possible explanations include sampling late in a patient’s hospital stay when virus load was lower, having insufficient contact time with a surface or using insufficiently moist collection swabs. Further environmental sampling studies of SARS-CoV-2 should consider including testing for the environmental presence of viruses within laboratory settings, targeting the collection of samples to early in the course of a patient’s illness and including sampling of confirmed positive control surfaces, while maintaining appropriate biosafety measures.

Objective: To describe and molecularly characterize an outbreak of dengue virus (DENV) infection in Cajamarca, an Andean region in Peru. Methods: A total of 359 serum samples from patients with acute febrile illness were assessed for the presence of DENV via RT-PCR, ELISA NS1, IgM and IgG in Cajamarca, Peru from January 2017 to June 2017. The evaluation of the different diagnostic tests and their applicability was performed. Results: Dengue virus was detected in 24.7% of samples by RTPCR. Meanwhile, serological analysis detected 30.3% positive cases via ELISA NS1 antigen, 16.7% via ELISA IgG and 9.7% via ELISA IgM. Most of the cases corresponded to DENV-3 (77.5%). The use of RT-PCR performed better in primary infections (P<0.01), while detection of ELISA IgM performed better in secondary infections (P<0.01). The combination of NS1 and IgM performed better than the other assays in detecting primary (92.5%) and secondary infections (96.6%). The most frequent symptoms associated with fever were headaches, myalgias, and arthralgias across all groups. Conclusions: We report an important outbreak of dengue infection caused by DENV-3 in Cajamarca, Peru. Our findings encourage the use of NS1 antigen and IgM co-detection. These findings demonstrate an increasing expansion of DENV-3 in Peru and highlight the importance of molecular diagnosis and serotype characterization among the clinically defined dengue cases to strengthen the Peruvian epidemiological surveillance.

Introduction:
Acne vulgaris is a common dermatologic disorder caused by follicular epidermal hyperproliferation, excess se-
bum production, inflammation, and Cutibacterium acnes (C. acnes). The mangosteen fruit rind contains large amount of xantho-
nes, which has high antimicrobial activity against C. acnes.
Objectives:
To compare the efficacy and safety of mangosteen 1% extract gel versus benzoyl peroxide (BPO) 5% gel in the treat-
ment of mild to moderate acne vulgaris.
Methods
A total of 60 participants with mild to moderate acne or a rating of 2 or 3 in the Investigator’s Global Assessment (IGA)
for acne were randomized to receive either mangosteen 1% extract gel or BPO 5% gel applied on the face twice daily over an
8-week period. Primary outcomes measured in the study were clinical remission graded as “clear” or “almost clear” (rating of 0 or
1) based on the IGA and any adverse reaction.

Introduction: Atopic dermatitis (AD) is a complex disease with an interplay of genetic and environmental factors. In the United States, AD affects 10.7% of children andyc 7.2% of adults. Similarly in the Philippines, the prevalence of AD is 12.7% in the under 18 population, and 2% in the over 18 population. While AD affects all ages, the burden of the disease is greater in the pediatric population. The pathogenesis of AD is multifactorial. Variations in genes responsible for epidermal barrier function, keratinocyte terminal differentiation, and the innate and adaptive immune responses have been linked to AD. A null mutation involving the filaggrin gene is the strongest known risk factor for AD. This mutation results in a loss of filaggrin (FLG) protein by at least 50%. Filaggrin breakdown products form part of the natural moisturizing factor (NMF) of the skin, which is essential in skin hydration. A decrease in NMF and an increase in transepidermal water loss (TEWL) are observed in AD patients with FLG mutation. The defective barrier in AD patients decreases skin defenses against irritation and allergen penetration. Exposure to certain environmental chemicals like formaldehyde may worsen this barrier. This may lead to increased skin permeability to aeroallergens that leads to dermatitis in sensitized patients. Barrier defects may also play a role in epicutaneous sensitization and the subsequent development of other atopic conditions, such as bronchial asthma and allergic rhinitis. The Philippine Dermatological Society (PDS) consensus on AD aims to provide a comprehensive guideline and evidence-based recommendations in the management of this condition, with consideration of cultural factors that are often encountered in the Philippine setting. These guidelines are intended to provide practitioners with an overview of the holistic approach in the management of AD, ameliorating the negative effects of the disease and improving overall quality of life..
Methodology: A group of 21 board-certified dermatologists from the Philippine Dermatological Society (PDS) convened to discuss aspects in the clinical management of AD. Database and literature search included the full-text articles of observational studies, randomized controlled clinical trials, and observational studies using the Cochrane library, PubMed, Hardin (for Philippine based studies) as well as data from the PDS health information system. The terms used in combinations from the literature included “atopic dermatitis”, “atopic eczema”, “emollients”, “topical corticosteroids”, “topical calcineurin inhibitors”, “anti-histamines” and “phototherapy”. A total of fifty (50) full text articles were reviewed and found applicable for the scope of the study. Articles were assessed using the modified Jadad scale, with score interpretations as follows: (5- excellent, 3- good, 1– poor). Consensus guidelines for AD from within and outside of the region were also reviewed, from the 2013 Asia-Pacific guidelines, 2014 Taiwanese Dermatological Association consensus, 2016 guidelines in the management of AD in Singapore, 2014 American Academy of Dermatology guidelines, and the 2020 Japanese guidelines for AD. From the literature review, proposed consensus statements were developed, and a Delphi survey was conducted over two separate virtual meetings. Individual dermatologists provided Likert Scoring (1-
strongly disagree to 5- strongly agree) based on consensus statements. A consensus was deemed reached at mean scores of > 4.00, a near consensus at > 3.5, and no consensus at <3.5.
Summary: AD is a chronic relapsing condition with a significant burden of disease, most commonly affecting the pediatric population. The PDS AD Consensus Guidelines summarizes the standards of therapy and the therapeutic ladder in the management of AD based on published clinical trials and literature review. While these modalities remain the cornerstone of therapy, an individualized approach is the key to the holistic management of an AD patient. Knowledge and awareness of frequently associated conditions, whether in the realm of food allergies, contact allergies, or secondary infections, is paramount. In addition to the standard therapeutic armamentarium, the physician must also consider cultural practices and be knowledgeable of alternative therapeutic options. Referral to a specialist is recommended for recalcitrant cases of AD, or when initiation of systemic immunosuppressive agents, phototherapy, or biologic agents is contemplated.

Malaria is a life-threatening disease caused by the Plasmodium sp. parasite.
Infection results in heightened pro-inflammatory response which contributes to the
pathophysiology of the disease. To mitigate the overwhelming cytokine response, host-directed
therapy is a plausible approach. Glycogen synthase kinase-3β (GSK3β), a serine/threonine
kinase plays a pivotal role in the regulation of inflammatory response during pathogenic
infections. The present study was conducted to investigate the chemo-suppressive and
cytokine-modulating effects of insulin administration in malaria-infected mice and the
involvement of GSK3β. Intraperitoneal administrations of 0.3 and 0.5 U/kg body weight
insulin each for four consecutive days into Plasmodium berghei NK65 (PbN)-infected mice
resulted in chemo-suppression exceeding 60% and improved median survival time of infected
mice (20.5 days and 19 days respectively compared to 15.5 days for non-treated control).
Western analysis revealed that pGSK3β (Ser9) intensity in brain samples from insulin-treated
(0.3 and 0.5 U/kg body weight) infected mice each were 0.6 and 2.2 times respectively than
that in control. In liver samples, pGSK3β (Ser9) intensity from insulin-treated infected mice
were significantly higher (4.8 and 16.1 fold for 0.3 and 0.5 U/kg bw respectively) than that in
control. Insulin administration decreased both brain and liver pNF-κB p65 (Ser536) intensities
(to 0.8 and 0.6 times for 0.3 U/kg bw insulin; and to 0.2 and 0.1 times for 0.5 U/kg bw insulin
respectively compared to control). Insulin treatment (0.5 U/kg bw) also significantly decreased
the serum levels of pro-inflammatory cytokines (TNF-α (3.3 times) and IFN-γ (4.9 times))
whilst significantly increasing the levels of anti-inflammatory cytokines (IL-4 (4.9 fold) and
IL-10 (2.1 fold)) in PbN-infected mice. Results from this study demonstrated that the cytokinemodulating effects of insulin at least in part involve inhibition of GSK3β and consequent
inhibition of the activation of NF-κB p65 suggesting insulin as a potential adjunctive therapeutic
for malaria.
