Introduction: Staphylococcus aureus is the leading biofilmforming microorganisms in orthopaedic implant infections.
The biofilms formed are difficult to eradicate and resistance
to antibiotics. This current study aims to determine the
effectiveness of povidone-iodine; an antiseptic solution in
eradicating S. aureus biofilm on stainless steel alloy. In
addition to the usual Colony-Forming Unit (CFU) used for
verification, Scanning Electron Microscope (SEM) is used to
validate the formation and eradication of the biofilms.
Materials and methods: This is an in vitro study where the
biofilm is formed by inoculating clinically isolated S. aureus,
incubated for 24 hours onto stainless steel alloy 316L
implants. The implants are then irrigated using povidoneiodine solution with varying concentrations (5 and 10%) and
durations (30, 60, and 180 seconds). The anti-biofilm effect
was evaluated using plating and SEM methods to confirm its
effectiveness. The process is repeated after 24 hours of postirrigation reincubation to detect any rebound growth.
Results: No biofilm seen after irrigation with povidoneiodine at 5% and 10% concentrations at 30, 60 and 180
seconds, respectively, in both CFU count and SEM. This
result is replicated after 24 hours of reincubation, in
assessing for rebound growth.
Conclusion: Our study supports that a minimum of 5%
povidone-iodine with a minimum irrigation time of 30
seconds are effective at eliminating S. aureus biofilm on
stainless steel alloy implants. Both CFU count and SEM
yield similar value in validating the presence of biofilm.
Additionally, SEM allows visualisation of the morphology of
the biofilm.

INTRODUCTION: Glaucoma is a leading cause of permanent blindness, often going
undetected in its early, asymptomatic stages, especially in older age groups. In
Malaysia, glaucoma is a growing public health issue due to an increase in the ageing
population. While screening is essential for early glaucoma detection, the most
suitable strategy for Malaysia's healthcare system remains unclear. This study
explored the perspectives of eye healthcare professionals on the most suitable
glaucoma screening strategies for Malaysia. MATERIAL AND METHODS: This
qualitative study used semi-structured interviews with 19 eye health professionals
(ophthalmologists, optometrists, nurses, ophthalmic technicians, and assistant
medical officers) practicing in the Klang Valley. The interviews were conducted
face-to-face in their workplace or via a video conferencing platform. All interviews
were recorded, transcribed, and analysed using thematic analysis. RESULTS: Six
major themes were identified: types of glaucoma screening programmes, accessible
screening locations, target screening population, instruments and use of digital
technology, trained personnel, and referral criteria. Opportunistic case finding and
population-based programmes were identified as the glaucoma screening
programmes in which trained personnel conducted screening at accessible
locations. Glaucoma screening for high-risk individuals was recommended,
focusing on visual acuity testing, tonometry, anterior chamber angle assessment,
funduscopy, perimetry, and retinal nerve fibre assessment. A lack of clear referral
criteria due to low awareness and poor implementation of existing guidelines was
observed. CONCLUSION: Further investigations are required to identify the best
combination of components for glaucoma screening. This will enable policymakers
to develop an effective glaucoma screening programme in Malaysia.

Introduction:
Adrenal incidentalomas are increasingly detected with
the widespread use of imaging, whereby the large or
heterogeneous lesions often raise concern for adrenocortical carcinoma (ACC). However, certain rare benign and infectious conditions may closely mimic malignant
features, posing a diagnostic challenge.
Case:
A 64-year-old female with diabetes mellitus, hypertension,
and dyslipidemia was noted to have progressively rising
alkaline phosphatase during routine follow-up. She had
non-specific gastrointestinal symptoms. A computed
tomography abdomen pelvis showed a large, lobulated
mass at the left flank, likely of adrenal origin. An adrenal
protocol computed tomography revealed a large,
heterogeneously enhancing left suprarenal mass measuring
10.7 × 10.3 × 10.7 cm, with a plain-phase attenuation of +81
Hounsfield Unit and absolute (28%) and relative (18%)
washout. The right adrenal gland was normal, with no
evidence of distant metastasis.
Hormonal evaluation showed normal 24-hour urinary
metanephrines, excluding pheochromocytoma. The
overnight dexamethasone suppression test demonstrated
cortisol of 89 nmol/L, suggestive of mild autonomous
cortisol secretion, without clinical features of overt
hypercortisolism. DHEA was low (0.371 µmol/L), and
adrenocorticotropic hormone was suppressed (1.26 pg/mL).
Evaluation for primary aldosteronism was not done due
to the absence of resistant hypertension or hypokalemia.
The gonadotropin profile was consistent with postmenopausal status (follicle-stimulating hormone (89 IU/L)
and luteinizing hormone (28.9 IU/L) with low estradiol.
The patient underwent open left adrenalectomy. Histopathology revealed an adrenal cavernous hemangioma
with extensive hemorrhage and infarction, alongside
necrotizing granulomatous inflammation with numerous
intracellular fungal organisms and narrow-based budding
yeast forms, highly suggestive of histoplasmosis, with
no evidence of malignancy. She was subsequently comanaged with infectious disease team and commenced on
intravenous amphotericin B.
Conclusion
This is a rare coexistence of an adrenal hemangioma
and histoplasmosis, presenting as a large adrenal
mass mimicking ACC. The limitations of imaging in
differentiating benign from malignant adrenal lesions
are revealed and emphasize the role of histopathological
confirmation. Increased awareness of such entities can
support the diagnosis and management.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):27-28
Introduction:
The identification of a significant adrenal mass in a patient
without a biopsy-confirmed malignancy poses a diagnostic
challenge: Is it a metastatic lesion or an underlying
adrenal condition? Adrenal metastases are the second
most common site of spread for lung adenocarcinoma;
approximately 3–7% of adrenal masses represent benign
adenomas. Diagnosis is even harder if there are signs of
primary aldosteronism (PA).
Case:
We present a case of a 62-year-old Chinese female with
a 10-year history of hypertension, managed on dual
antihypertensive therapy, who presented for evaluation
of suspected PA following the discovery of hypokalemia.
Biochemical screening revealed an elevated aldosteronerenin ratio (ARR, 65). The overnight dexamethasone
suppression test (20 nmol/L) and testosterone (0.79 nmol/L)
were both within normal limits. Saline Suppression Test
(SST) showed an indeterminate post-infusion aldosterone
level (202.8 pmol/L). Cross-sectional imaging via computed
tomography (CT) Adrenals identified a large, 6.4 × 5.4 × 6.2
cm heterogeneous left suprarenal mass with a low mean
attenuation (8.6 Hounsfield Unit [HU]). Concurrently, an
incidental left upper lobe pulmonary lesion was identified,
and PET-CT was performed; the SUVmax of the lung was
identical to that of the adrenal lesion. An ultrasoundguided biopsy of the pulmonary lesion confirmed
estimated glomerular filtration rate-mutation-positive lung
adenocarcinoma. The patient started on targeted therapy
with dacomitinib. Follow-up CT imaging at 9 months
demonstrated disease progression within the thorax, marked by the appearance of a new pulmonary nodule.
Notably, however, the adrenal mass remained stable in size
and morphology.
Conclusion
The absence of mixed androgen/glucocorticoid hypersecretion, combined with the radiographically static nature
of the mass, suggests a lower probability of adrenocortical
carcinoma. This case highlights that while size is a major
risk factor for adrenocortical carcinoma, it must be
interpreted in conjunction with hormonal activity, HU, and
growth patterns. Identifying these “mimics” helps avoid
over-staging lung cancer and ensures patients receive
targeted therapy instead of unnecessary adrenalectomies.
5.When Tissue Is the Issue: Presumptive Diagnosis and Treatment of Bilateral Adrenal Tuberculosis

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):30-
Introduction:
Adrenal tuberculosis (TB) is a rare but important cause
of adrenal insufficiency in TB-endemic regions, usually
secondary to pulmonary or extrapulmonary disease, with
primary involvement being uncommon. It typically affects
both glands via hematogenous or lymphatic spread and
presents late with nonspecific features after significant
adrenal destruction, making diagnosis challenging.
Diagnosis is more straightforward in the presence of extraadrenal TB, where imaging may obviate the need for biopsy,
but remains difficult in isolated adrenal involvement.
Case:
We report a 69-year-old Malay male with diabetes
mellitus, hypertension, and hyperlipidemia who presented
with a 2-week history of chronic cough and 4 months
of constitutional symptoms, including weight loss and
anorexia. Initial TB workup in September 2025 was negative.
He was subsequently admitted twice in October 2025 for
pneumonia, with persistent upper lobe consolidation on
chest radiography despite antibiotics.
Contrast-enhanced computed tomography thorax,
abdomen, and pelvis revealed bilateral mildly enhancing
hypodense adrenal lesions (right 3.7 × 3.0 cm, left 2.5 × 2.6
cm), suggestive of adenoma, hyperplasia, or lymphoma.
Bronchoscopy detected Mycobacterium tuberculosis via
GeneXpert BAL, with no malignant cells on cytology.
Adrenal biopsy was non-diagnostic.
Biochemical evaluation showed low morning cortisol
with elevated adrenocorticotropic hormone and findings
consistent with adrenal insufficiency. The patient was
treated as smear-negative pulmonary TB with adrenal
involvement and initiated on anti-TB therapy, currently in
the maintenance phase. Hydrocortisone replacement 10 mg
twice daily was also initiated.
Conclusion
This case highlights the diagnostic challenge of adrenal
TB, particularly when tissue sampling is inconclusive. In TB-endemic settings, a presumptive diagnosis based on
clinical, radiological, and microbiological evidence is often
necessary. Early empiric anti-TB therapy is essential to
prevent adrenal crisis and preserve endocrine function.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):42-43
Introduction:
The 2021 IDF-DAR risk calculator had been previously
evaluated in multiple studies and subsequently widely
accepted and applied in clinical practice as a practical
standardized tool for patient risk stratification. Recently
updated, the 2026 IDF-DAR Risk calculator enables a more individualized, evidence-related evaluation of patientrelated and disease-related risk factors, incorporating
modern diabetes technologies, including continuous
glucose monitoring (CGM), automated insulin delivery
(AID) systems, and advanced insulin formulations to
enhance risk stratification. This tool allows medical
professionals to tailor Ramadan practices based on overall
factors toward promoting safe fasting.
Methodology:
This prospective multicentre observational study recruited
adults with Type 1 and Type 2 diabetes attending public
hospitals nationwide. People with diabetes (PwD) intending
to perform Ramadan fasting were invited to participate
and assessed using the 2026 IDF-DAR Risk Calculator in
the 6-week pre-Ramadan period between 30th January and
19th March 2026.
Results:
A total of 458 PwD were evaluated and stratified into low
(15.7%), moderate (41%), and high risk (43.3%) categories.
Most participants had Type 2 diabetes (83.6%), with 60.3%
having a disease duration exceeding 10 years and 43%
exhibiting poor glycemic control (hemoglobin A1c >9%).
Insulin therapy was used by 76.4% of participants, including
two individuals with Type 1 diabetes using AID systems.
Most participants reported no recent hypoglycemia (76.4%),
81.0% performed glucose monitoring, and 3.3% used CGM.
Severe comorbidities were uncommon, with 1.1% having
unstable macrovascular disease and 4.4% advanced chronic
kidney disease (estimated glomerular filtration rate <30).
Notably, 72.2% received structured Ramadan education.
Conclusion
Majority of PwD attending tertiary diabetes clinics were
in the moderate- to high-risk category and intended to
fast despite medical advice against fasting in some cases.
Although most participants were on insulin therapy,
hypoglycemia was low in the pre-Ramadan period.
Integration of modern technologies, advanced insulin
therapies, and structured education may support safer
fasting practices.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):47-48
Introduction:
Gestational diabetes mellitus (GDM) is a common pregnancy complication associated with adverse maternal and
neonatal outcomes, including hypertensive disorders,
caesarean delivery, macrosomia, and increased lifetime
risk of type 2 diabetes. Despite its clinical importance,
considerable international variation exists in GDM
screening and diagnostic criteria. Multiple frameworks are currently used, including those from the World Health
Organization (WHO), International Association of Diabetes
and Pregnancy Study Groups, Carpenter and Coustan, and
the National Diabetes Data Group. Differences in glucose
thresholds, testing protocols (one-step versus two-step),
and universal versus risk-based screening contribute
to heterogeneity in reported prevalence and healthcare
burden. In multi-ethnic, middle-income settings such as
Malaysia, identifying an evidence-informed and contextappropriate diagnostic approach is critical.
Methodology:
This scoping review follows the Joanna Briggs Institute
methodology and will be reported in accordance with the
PRISMA Extension for Scoping Reviews (PRISMA-ScR).
PubMed, Scopus, and ScienceDirect will be searched for
English-language studies, reviews, guidelines, and consensus statements reporting GDM diagnostic criteria. Two
reviewers will independently screen and select studies.
Results:
Data will be charted on country, study type, diagnostic
criteria, gestational age at screening, and reported
challenges. Findings will be synthesized descriptively and
presented in tables and figures. No formal risk-of-bias
assessment will be conducted.
Conclusion
This review will provide a comprehensive overview of
global diagnostic practices, highlight variations and gaps,
and support evidence-based selection of a suitable GDM
screening and diagnostic strategy for Malaysia.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):61-
Introduction:
Polycystic ovarian syndrome (PCOS) is a complex
endocrine disorder that significantly affects adolescent
girls, particularly those with overweight or obesity.
However, data examining the determinants and metabolic
profiles of PCOS among adolescents with overweight
and obesity remain limited, especially in Malaysia. This
protocol describes a case-control study investigating the
cardiometabolic, dietary, and psychosocial determinants of
PCOS among adolescents with overweight and obesity.
Methodology:
This study is designed as a case-control study involving
adolescent girls aged 13–16 years with a body mass
index z-score >+1 standard deviation. Cases are defined as adolescent girls with a confirmed diagnosis of PCOS
based on the recommendations of the 2017 International
Consortium of Paediatric Endocrinology (ICPE), while
controls are those who do not meet the diagnostic criteria
for PCOS. A total sample size of 440 participants is required.
Participants will be recruited from 22 secondary schools
selected from a list of schools in Kuala Lumpur. Data on
sociodemographic characteristics, psychosocial health,
physical activity, and dietary intake will be collected using
structured questionnaires. Blood samples will be obtained
and analyzed for diagnostic testing (free testosterone),
exclusion tests (thyroid-stimulating hormone, folliclestimulating hormone, luteinizing hormone, estradiol,
prolactin, and dehydroepiandrosterone sulfate), and
biochemical parameters (liver function tests, lipid profile,
hemoglobin A1c, fasting glucose, fasting insulin, and
inflammatory markers).
Results:
The study is expected to generate comprehensive data on
the cardiometabolic, dietary, and psychosocial determinants of PCOS among adolescents with overweight and
obesity. The findings will inform early screening strategies
and targeted interventions aimed at reducing long-term
reproductive and cardiometabolic complications.
Conclusion
This protocol outlines a structured approach to investigating PCOS in adolescence and addresses current gaps
in early identification and risk stratification among highrisk populations.

9.Extra-Adrenal and Unexpected: A Rare Case of Primary Retroperitoneal Paraganglioma
Raja Nurul Azafirah Raja Amir Shah ; Masliza Hanuni Mohd Ali ; Wan Mohd Hafez Wan Hamzah ; Nor Hisham M
Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):66-
Introduction:
Paragangliomas are rare neuroendocrine tumors arising
from extra-adrenal chromaffin cells, with an estimated
incidence of 2–8 cases per million per year. These tumors
originate from neural crest–derived cells of the sympathetic
and parasympathetic paraganglia and may secrete
catecholamines, resulting in malignant hypertension or
symptoms such as headache, palpitations, and diaphoresis.
They can occur anywhere along the paravertebral and
para-aortic regions from the skull base to the pelvic floor.
Case:
We report a case of a 14-year-old male with no known
premorbid conditions who presented with presyncope
and a 1-month history of headache. On examination, he
had severe hypertension (242/167 mmHg), tachycardia
(127 bpm), and grade IV hypertensive retinopathy.
Investigations showed preserved renal function with
markedly elevated 24-hour urinary metanephrines
(normetanephrine 90.75 µmol/L). Computed tomography
revealed a lobulated, heterogeneously enhancing mass
measuring 5.0 × 6.1 × 5.4 cm along the left margin of the
abdominal aorta at the infrarenal level, suggestive of an
extra-adrenal lesion. Gallium-68 PET scan demonstrated
a somatostatin receptor–avid left peritoneal mass. The
patient underwent exploratory laparotomy and tumor
excision, complicated intraoperatively by blood pressure
lability requiring nitroprusside and inotropic support.
Postoperatively, he improved significantly and was able to
wean off all antihypertensive medications. Histopathology
confirmed left retroperitoneal paraganglioma.
Conclusion
Primary peritoneal paraganglioma is a rare but important
cause of secondary hypertension, especially in young
patients presenting with hypertensive emergency.
High index of suspicion is essential for early diagnosis.
Management requires a multidisciplinary approach
with careful preoperative optimization to minimize perioperative complications. Surgical resection remains the
definitive treatment and, as demonstrated in this case, can
result in marked clinical improvement with resolution
of hypertension.

10.Craniofacial Brown Tumor Secondary to Persistent Multiglandular Primary Hyperparathyroidism: A Reversible Complication
Fathiyah Ramly ; Siti Sanaa Wan Azman ; Masliza Hanuni Mohd Ali ; Wan Mohd Hafez Wan Hamzah
Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):76-
Introduction:
Brown tumors, also known as osteitis fibrosa cystica, are
focal bone lesions resulting from increased osteoclastic
activity and fibroblastic proliferation. They represent a
rare complication of uncontrolled hyperparathyroidism
(HPT) and may affect any part of the skeleton, including
craniofacial bones.
Case:
We report a case of a 31-year-old Malay female diagnosed
with primary HPT secondary to multiglandular disease,
who initially presented with symptomatic hypercalcemia.
Biochemical evaluation revealed elevated corrected calcium
(2.84 mmol/L; reference range 2.2–2.6 mmol/L), low
phosphate (0.63 mmol/L; reference range 0.8–1.6 mmol/L),
and markedly elevated serum intact parathyroid hormone
(iPTH) (286 pg/mL; reference range 14.9–56.9 pg/mL).
Ultrasound parathyroid showed a large right extrathyroidal
lesion, most likely suggestive of parathyroid adenoma,
where sestamibi scan suggested multiglandular parathyroid adenomas with possible mediastinal involvement. She
underwent exploratory parathyroidectomy on 19 June 2024,
with excision of bilateral inferior parathyroid adenomas
confirmed on histopathology. Despite surgery, she had
persistent hypercalcemia (2.8–3.1 mmol/L) and rising iPTH
levels (307 pg/mL on 24 June 2024, increasing to 413 pg/mL by
2 September 2024), consistent with persistent disease. Repeat
imaging demonstrated hyperfunctioning parathyroid tissue
in the anterior mediastinum. Subsequently, the patient
developed progressive enlargement of the left upper gingiva
associated with significant pain during mastication. Clinical
and radiological evaluation revealed aggressive lesions
with cortical expansion. Excisional biopsy of the gingival
lesion confirmed the diagnosis of brown tumors involving
the jaws. She later underwent a second parathyroidectomy
with intraoperative parathyroid hormone monitoring at
another centre. Postoperatively, normalization of serum
calcium and iPTH levels was achieved, which led to marked
clinical improvement and regression of the craniofacial
brown tumor.
Conclusion
This case highlights that skeletal manifestations of HPT,
including brown tumors, may regress following adequate
biochemical control without additional local therapy. Early
recognition and definitive surgical management of persistent or ectopic hyperfunctioning parathyroid tissue are
essential to prevent progression and promote spontaneous
bone healing processes.
