Introduction: Adrenocortical carcinoma (ACC) is an aggressive malignancy with high rates of recurrence even after surgical resection. Surgery remains the mainstay of treatment, while adjuvant options are limited. Mitotane is the only approved systemic therapy. Current guidelines recommend stereotactic body radiotherapy (SBRT) alongside adjuvant mitotane therapy in Rx, R1, R2 resections and in locally advanced disease. Case: We present a case of a 40-year-old female who presented with abdominal pain and was found to have a large heterogeneous left adrenal mass measuring 8.2 × 8.5 × 9.5 cm (Hounsfield Unit 63) on computed tomography (CT) imaging. Clinically, she was obese with a body mass index of 33.7 kg/m². No discriminatory feature of Cushing’s was present. Hormonal evaluation demonstrated autonomous cortisol secretion with failure of suppression on both overnight and low-dose dexamethasone suppression tests at 301 nmol/L and 313.6 nmol/L, respectively. DHEA, testosterone, and urinary metanephrine were within range. Hemoglobin A1c was 6.6%. She underwent open left adrenalectomy. Intra-operatively, a 12 × 10 cm adrenal tumor was identified with multiple areas of tumor rupture and spillage during mobilization. HPE confirmed high-grade ACC with high Weiss score of 8, Ki-67 index 60–80%, and mitotic count 54/50 hpf (pT2Nx). Post-operative CT imaging demonstrated a residual soft tissue lesion in the left adrenal bed (largest diameter 3.8 cm) with fluorodeoxyglucose avidity. We commenced adjuvant mitotane therapy, titrated to 2 g TDS with supraphysiological hydrocortisone replacement. Mitotane level was within therapeutic range (16 mcg/mL). She was deemed unsuitable for repeat surgery due to the proximity of the residual mass to the adjacent vessel and was planned for SBRT therapy after a multidisciplinary team discussion. Conclusion High-risk ACC with suspected residual disease remains a therapeutic challenge. While mitotane remains the cornerstone of adjuvant therapy, SBRT may represent a promising adjunctive local treatment modality in carefully selected patients. Further studies are required to define its role in improving local control and outcomes in ACC.

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.

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.

Introduction: Permanent hypoparathyroidism is a recognized complication of total thyroidectomy, with an estimated incidence of 10.47%. Standard treatment involves supplementation with calcium and activated vitamin D. However, some patients remain refractory to conventional therapy and fail to achieve normocalcemia. During pregnancy, significant physiological changes occur in calcium-regulating hormones. Notably, the placenta increases the production of parathyroid hormone-related peptide (PTHrP), which acts as a calcitropic hormone, mimicking the effects of parathyroid hormone. Case: A 38-year-old female with a history of total thyroidectomy 14 years ago for follicular thyroid carcinoma presented with permanent hypoparathyroidism. Her condition was refractory to high-dose replacement therapy, which included calcium carbonate 3 g BD, alfacalcidol 4 mcg ON, calcitriol 1 mcg BD, and cholecalciferol 100,000 IU OD. Despite compliance, her serum calcium levels fluctuated between 1.7 and 1.93 mmol/L, necessitating intermittent intravenous calcium infusions. Laboratory investigations showed a phosphate level of 1.63 mmol/L and 24-hour urine calcium of 4.81 mmol/L. Her thyroid function remained stable on levothyroxine 150 mcg daily (T4: 12.0 pmol/L; thyroid-stimulating hormone: 2.93 mIU/L). While off-label use of teriparatide was being considered, she became pregnant. As the pregnancy progressed, her calcium levels stabilized. Calcitriol was discontinued at 26 weeks’ gestation when her calcium reached 2.5 mmol/L. By 30 weeks, the alfacalcidol dose was reduced to 3.5 mcg daily, with cholecalciferol dosing reduced to 50,000 IU OD. Her corrected calcium levels remained between 2.4 and 2.6 mmol/L until delivery. Similar reduction in supplementation requirements was noted during her previous pregnancy. Conclusion Elevated PTHrP during pregnancy likely contributed to improved calcium homeostasis by increasing maternal bone resorption and enhancing placental calcium transfer. This case underscores the necessity of individualized, dynamic adjustments to calcium and vitamin D therapy based on rigorous biochemical monitoring for pregnant patients with hypoparathyroidism.

Introduction: Immunoglobulin G4-related hypophysitis (IgG4-RH) is a rare fibro-inflammatory disorder affecting the pituitary gland. Glucocorticoids remain the first-line therapy, but their use may be complicated in patients with significant metabolic comorbidities. We report a case of suspected IgG4-RH presenting with hyperosmolar hyperglycemic state (HHS), highlighting the challenges of balancing disease control against glucocorticoid metabolic toxicity adverse effects. Case: A 32-year-old female with obesity and newly diagnosed diabetes mellitus was admitted with HHS. Prior to admission, she reported weight fluctuations, episodic headaches, progressive visual disturbance, and secondary amenorrhea. Following resolution of HHS, persistent polyuria of 10–16 L/day prompted further evaluation and led to a diagnosis of arginine vasopressin deficiency. Anterior pituitary hormonal work-up revealed hypogonadotropic hypogonadism. Pituitary magnetic resonance imaging demonstrated infundibular thickening measuring 0.5 cm, with concomitant marked bilateral parotid enlargement. Serum IgG4 was elevated at 2.26 g/L (0.63–2.01), raising strong suspicion for IgG4-RH with systemic involvement. Histopathological confirmation from the parotid gland biopsy was consistent with sialadenosis. She was commenced on sublingual desmopressin and cyclical sex hormone replacement therapy. Given the provisional diagnosis of IgG4-RH, oral prednisolone 40 mg daily was initiated as a reduced induction regimen. However, treatment was poorly tolerated, with rapid weight gain from 93 to 100 kg and worsening glycemic control. Prednisolone was therefore tapered rapidly to 10 mg daily. Repeat imaging demonstrated interval improvement in infundibular thickening, but no functional endocrine recovery was observed. Conclusion This case illustrates the therapeutic challenge of managing IgG4-RH in the setting of pre-existing metabolic syndrome. Although glucocorticoids are effective for induction, their metabolic adverse effects may significantly restrict treatment tolerability. Early consideration of steroidsparing agents, such as rituximab or azathioprine, may be important to achieve remission while minimizing glucocorticoid-related adverse effects.

Introduction: Short stature and delayed puberty characterize Turner syndrome (TS). The 2024 international clinical practice guidelines recommend growth hormone (GH) for latediagnosed patients if epiphyses remain open. For patients with remaining growth potential, initiating GH alongside low-dose estrogen effectively balances linear growth with the need for timely pubertal induction. Case: A 15-year-old female, born prematurely at 6 months gestation, presented with delayed puberty, primary amenorrhea, and short stature. Examination revealed a height of 122 cm (<5th percentile), weight of 26 kg, with no syndromic facies, and Tanner stage 1. Investigations confirmed hypergonadotropic hypogonadism. Metabolic screening, including thyroid, renal, and liver profile, was normal. Her baseline insulin-like growth factor 1 (IGF-1) was low at 117.5 ng/mL (127.5–541.5). Karyotyping confirmed mosaic TS (45,X/46,Xr). Her skeletal bone age was delayed at 12 years, indicating a viable window for linear growth prior to complete epiphyseal fusion. Subcutaneous GH was initiated at 0.3 mg up titrated to 1.2 mg (0.45 µg/kg) daily over 4 weeks, then 1.35 mg (50 µg/kg) daily at month 5. Low-dose oral estradiol (0.5 mg three times weekly) was introduced for pubertal induction at month 4. After 9 months of combined GH and estrogen therapy, the patient achieved a height increment of 6 cm, reaching 128 cm without an adverse event. To achieve the clinical target of a 10–15 cm increment in the first year, her GH dose was further increased to 1.50 mg (55 µg/kg) daily. She showed an appropriate biochemical response with IGF-1 increased to 40.2 nmol/L (16.4–67.8) with a total height gain of 6 cm over the first 9 months of GH therapy. Conclusion Concomitant GH and estrogen therapy in late-diagnosed TS successfully induced clinically significant height gain. This dual approach maximized the limited window for linear growth, without delaying pubertal induction and compromising patient’s psychosocial well-being.

Introduction: C-reactive protein (CRP), urea, albumin, CRP/albumin ratio (CAR) and urea/albumin ratio (UAR) could be valuable biomarkers for determining the severity of illness in patients with COVID-19. This study aimed to determine the association between these markers and disease severity in COVID-19 patients on admission and days five to seven after admission. Methods: This retrospective study includes 153 adult COVID-19 patients admitted to Hospital Raja Perempuan Zainab II and Hospital Ampang from January 2021 to December 2021. Patients’ serum CRP, urea, albumin and creatinine levels were recorded on admission and on days five to seven after admission. The patients were categorised based on the Annex 2e guidelines published by the Ministry of Health, Malaysia and further classified as mild to moderate disease (stages 1-3) and severe to critical illness (stages 4-5). Results: On admission, urea, creatinine, CRP, UAR and CAR were significantly higher in the severe to critical group (p<0.001). The optimal cut-off value for the UAR was 0.16; the area under the curve (AUC) was 0.760, and sensitivity and specificity were 63.6% and 85.7%, respectively. The AUC of the CAR was 0.752, with 54.2% sensitivity and 91.4% specificity at an optimal cut-off value of 1.63. In severe to critical COVID-19 patients, albumin levels decreased significantly on days five to seven after admission, while urea levels remained significantly higher in this group (p<0.001, p<0.05, respectively). Conclusion: CRP, urea, albumin, CAR and UAR are promising biomarkers for predicting the severity of disease in COVID-19 patients.

Aims: The aquaculture industry has been identified as one of the sources for the emergence of antimicrobial resistant bacteria. This study aimed to determine the level of bacterial contamination from selected catfish pond farming at Jasin, Melaka and its susceptibility to antimicrobial agents. The correlation between the sampling points’ Water Quality Index and the level of bacterial contamination was also determined. Methodology and results : Sampling was carried out at six sampling points of the river as well as selected catfish pond farming. Microbial counts were assessed using the membrane filtration and isolates were further identified by using the polymerase chain reaction (PCR) method. Antimicrobial susceptibility tests were carried out using the disk diffusion method. Results showed that the total bacterial count obtained was not significantly different (P>0.05) between sampling points with an average of 4.47 ± 0.41 log CFU/mL. A total of 27 different bacterial species were identified where 63% were identified as Gram-negative bacteria. A medium negative correlation (r=-6.16, P<0.01) was found between the sampling points’ Water Quality Index and the level of bacterial contamination. Among bacterial species identified, 18 species are pathogenic strains. Conclusion, significance and impact of study Antibiotic susceptibility test indicated that only 4 isolates showed resistance to antimicrobials tested and the study shows the potential cross contamination between fishponds and Kesang River, Melaka. Thus, public health concerns are tangible, and prevention of the cross contamination is crucial for the farm.

Introduction: Daily use and improper management of plastic materials by the public contributes to the occurrence of microplastic pollution. It can be acknowledged that knowledge and attitudes are one of the keys to reducing the release of microplastic into the environment. Therefore, enhancing student’s understanding may play an important role in effective solution innovation and readiness to take specific actions for environmental protection. Method: This cross-sectional study was conducted among university students using an online questionnaire to assess their knowledge and attitudes about microplastic pollution. For data analysis, Pearson’s Chi-square was conducted using SPSS version 26. Results: Findings revealed that students have moderate knowledge (4.66) and attitudes (5.42) towards microplastic pollution. However, neither age, gender, CGPA, nor the course in which they studied had any significant association with their level of knowledge and attitudes (p>0.05). In fact, the level of knowledge and attitude reported by respondents indicate that it is necessary to address this deficiency by providing education through structured education and mass media, along with vigorous policy enforcement and replacement of conventional plastics. Conclusion: Education on microplastics among the younger generation is key to curbing the problem of microplastic pollution. As future consumers, the demand for alternative products that does not contribute to microplastic can help encourage brands and markets to come up with better solution that is critical to prevent this problem from worsening.

Introduction: Laboratory tests account for 66% of clinical decision making and reducing inappropriate test utilisation is a step towards optimising patients’ care and hospital cost savings. This study aims to identify the rate and cost of redundant test requests in our centre. Methods: A cross-sectional study comprising laboratory results of 14 analytes in renal function test (RFT) and liver function test (LFT) were made. Data involved blood results from adult patients admitted to Hospital Universiti Sains Malaysia from January to December 2018. The redundant test is defined as test results consecutively normal twice and requested within 26 hours for analytes in RFT and 50 hours for analytes in LFT. Cost contributions were estimated by multiplying cost-per-test with total redundant requests. The test redundancy in different wards and disease groups were also evaluated. Results: Equal distribution of RFT and LFT requests were observed in both genders (50% respectively), with the most requests seen in the 60 – 79 years age group. More than 20% redundancy rate was observed for seven analytes (ALT, total bilirubin, sodium, urea, potassium, AST, Chloride), and overall redundancy was 19.7%, equals to Malaysian Ringgit (MYR) 669,105.00. Oncology wards and genitourinary diseases contribute to the highest redundancy rate. Conclusion: This study estimated MYR 600 thousands of saving if test redundancy were to be eliminated. The finding is hoped to serve as a platform for future intervention and policymaking. Future planning to optimise the current laboratory request system and collaboration among physicians and laboratory professionals can minimise test inappropriateness.
