Distal vaginal agenesis (DVA) is a rare form of female genital tract malformation that presents as cryptomenorrhea. It results from the failure of the urogenital sinus to form the caudal portion of the vagina. Through a thorough history, physical examination and appropriate imaging studies, an accurate diagnosis is integral in selecting the correct intervention for the patient. This is a case of distal vaginal agenesis in a 10-year-old nulligravid, who presented with fecal retention from an abdominopelvic mass. The patient had no bowel movement for four days, and abdominal enlargement. On inspection, there was a 12.0cm x 10.0cm palpable abdominal mass. Inspection of the external genitalia, the introitus appeared concave, with no appreciable introital opening. On digital rectal examination, an anterior bulge was palpated 0.5 cm from the anal verge. A pull-through vaginoplasty was performed with an unremarkable post-operative course. The patient was discharged with a patent vagina and resolution of her gastrointestinal symptoms. On follow-up, the patient had monthly menstruation after surgery with no recurrence of her gastrointestinal symptoms.

OBJECTIVE

This paper reports a rare presentation of diffuse intraocular inflammation following reversed vaulted multipiece intraocular lens (IOL) implanted in the sulcus of a 7-year-old child.

This is a case report.

A 7-year-old child presented with persistent posterior pole inflammation and optic disc swelling after an improperly placed multipiece intraocular lens in the sulcus. Comprehensive eye and wholebody evaluations were performed with the aid of optical coherence tomography (OCT), magnetic resonance imaging (MRI) and systemic work-up to rule out other causes of uveitis to definitively diagnose the case. The reverse-vaulted lens was eventually explanted. After 1 week post-explantation, the visual acuity improved markedly to 20/100 with the appropriate spectacle prescription. The patient recovered from the ocular inflammation 8 months postoperatively.

This paper reports significant posterior pole inflammation as an uncommon yet potentially visually-disabling consequence of a reverse-vaulted sulcus placement of a multipiece intraocular lens in a child. Careful attention is warranted to ensure proper IOL orientation during implantation, especially in pediatric cataract surgery. Visual rehabilitation is important postoperatively

Introduction: ISPAD guidelines recommend continuous glucose monitoring (CGM) as the standard of care for paediatric type 1 diabetes (T1DM). However, a “real-world” adoption gap persists, particularly in resource-limited settings. The Introductions of the study were to evaluate CGM adoption prevalence, identify documented barriers, and compare glycemic outcomes between active and non-active users. Methodology: This retrospective review analyzed electronic medical records (EMR) of 125 paediatric T1DM patients at Hospital Putrajaya (2025). Data included CGM status, insulin delivery method, and documented barriers. Independent T-tests compared mean hemoglobin A1c (HbA1c) between groups, and multivariable logistic regression identified independent predictors of adoption. Results: Cohort mean age was 11.8 ± 3.8 years. Active CGM users were 32.8% (n = 41), of whom 29.3% (n = 12) utilized predominantly automated insulin delivery (AID) systems. The remaining 67.2% (n = 84) were classified as non-active users, comprising both never-users and ex-users (discontinued use). Active users achieved significantly lower mean HbA1c than non-active users (8.73% vs 9.86%; p <0.001), with no significant difference in rates of DKA (p = 0.564) or severe hypoglycemia (p = 0.250). Among never-users, 42.9% lacked documented technology counselling (p = 0.001). Multivariable analysis identified funding source as the sole independent predictor of CGM adoption (adjusted OR = 7.76, p <0.001). While the primary documented barrier was financial (31.0%), a lack of documented barriers was noted in 61.9% of non-active users. Conclusion A substantial technology gap exists, primarily driven by financial access rather than clinical demographics. The difference of 1.13% in HbA1c between groups underscores the need to address financial setbacks to improve technology access in Malaysia and prevent diabetes complications.

Introduction: Arginine vasopressin deficiency (AVP‑D), previously termed central diabetes insipidus, is a rare paediatric endocrine disorder that may present as an early manifestation of diverse hypothalamic–pituitary conditions. Identifying the underlying etiology is crucial for guiding management and surveillance; however, in some children, the cause remains unresolved, leading to primarily symptomatic treatment. In Malaysia, published literature on paediatric AVP‑D has been limited to isolated case reports, with no cohort‑level data available. This study aims to describe the clinical features, etiological spectrum, and treatment patterns of paediatric AVP-D in a single-centre Malaysian cohort, emphasizing diagnostic yield, unresolved causes, and the central role of neuroimaging. Methodology: A retrospective review was conducted of children diagnosed with AVP-D. Data collected included age at symptom onset, age at presentation, clinical features, etiological classification, neuroimaging findings, comorbidities, treatment modalities, and follow-up outcomes. Descriptive statistics were used for analysis. Results: Twelve children were included, with a median age of 9.8 years; two-thirds were male. Children were referred at a median age of 3.4 years, with presentation ranging from the neonatal period to 10.4 years. Diagnostic delay was minimal overall, although 25% experienced delays exceeding 1 year. The water deprivation test was performed in 33.3% of patients. Magnetic resonance imaging (MRI) was completed in all children and served as the principal determinant of etiology. Structural abnormalities were identified in 50% of the cohort, including semilobar holoprosencephaly (33.3%), Arnold– Chiari I malformation (8.3%), and pituitary stalk interruption syndrome (8.3%). The posterior pituitary bright spot was absent in most patients, and 50% required repeat MRI to clarify evolving neurohypophyseal features. Tumor-related AVP-D accounted for 8.3%, while one-third had no definitive etiology despite imaging. Initial therapy included desmopressin (58.3%), hydrochlorothiazide (25%), and diluted sublingual desmopressin (8.3%), with most requiring dose escalation. Growth impairment occurred in 66.7% of patients, and delayed puberty in 16.7%. Conclusion MRI played a central role in defining etiology, with half of the cohort demonstrating congenital structural abnormalities. Persistent unresolved cases highlight the diagnostic challenges of AVP-D and underscore the importance of early MRI and longitudinal endocrine follow-up.

Introduction: X-linked hypophosphatemia (XLH) is a rare genetic disorder caused by PHEX mutations, characterized by chronic hypophosphatemia and renal phosphate wasting, resulting in skeletal, dental, and extra-skeletal complications. To date, no data from Malaysia are currently available on clinical characteristics or health-related quality of life (HRQoL) in paediatric patients. Methodology: This cross-sectional study evaluated HRQoL among children and adolescents with XLH, using validated PROMIS (PatientReported Outcomes Measurement Information System) instruments, sociodemographic and clinical factors associated with HRQoL. This includes children and adolescents with confirmed XLH followed up at Universiti Malaya Medical Centre (UMMC) between November 2024 and March 2025. Results: Seventeen patients were analyzed (76.5% female and 23.5% male). The mean age at symptom onset was 2.82 ± 2.42 years, with a mean age at diagnosis of 5.21 ± 3.29 years. All patients continued to have musculoskeletal complications, including short stature (76.5%), bowing of legs (76.5%), bone/joint pain (47.1%), muscle pain (47.1%), and dental complications (52.9%). Serum alkaline phosphatase improved significantly (p = 0.011); persistent hypophosphatemia and ongoing musculoskeletal manifestations indicated suboptimal disease control. Elevated parathyroid hormone levels and an increase in urine calciumto-creatinine ratio (p = 0.020) lead to secondary hyperparathyroidism and nephrocalcinosis. Adherence to conventional therapy was poor. Non-adherence was associated with worse pain outcomes (higher pain interference [p = 0.037] and greater pain intensity [p = 0.025]). PROMIS scores revealed severely impaired mobility (mean T-score 31.31 ± 12.17), increased fatigue (mean T-score 54.22 ± 7.60), and high pain interference (mean T-score 63.11 ± 9.50). Larger household size was also strongly associated with higher pain intensity (p = 0.004). Conclusion Malaysian children and adolescents with XLH continue to have significantly poor HRQoL, particularly in mobility, fatigue, and pain. These findings highlight the need for access to targeted therapies, such as burosumab, to improve long-term outcomes and QOL in XLH patients.

Introduction: Hyperthyroidism in children and adolescents, although uncommon, has significant effects on growth, neurodevelopment, and quality of life. Local data in Malaysia are limited, and regional variations may influence disease presentation and outcomes. This study aimed to determine the incidence, clinical characteristics, and treatment outcomes of paediatric hyperthyroidism at a tertiary centre. Methodology: A retrospective cohort study was conducted at the Paediatric Endocrine Clinic, Universiti Malaya Medical Centre, from 2014 to 2024. Patients aged below 18 years with confirmed hyperthyroidism were included. Demographic, clinical, biochemical, and treatment data were analyzed. Descriptive statistics were used, and associations were tested using chisquare and Fisher’s exact tests, with p <0.05 considered significant. Results: Forty-three patients were included, representing 9.7% of paediatric thyroid disorders. The cohort was predominantly female (74.4%) and majority Malay, with a median age of 11.7 years. Most patients presented with typical features, including palpitations (72.5%), goiter (62.5%), weight loss (45.0%), and heat intolerance (40.0%). However, atypical presentations such as learning difficulties and psychological disturbances were also observed and, in some cases, constituted the chief complaints. Notably, 82.5% of patients presented with severe thyrotoxicosis. Grave’s disease was the predominant etiology. All patients received antithyroid drugs, mainly carbimazole, with 80.0% achieving disease control and a median time to euthyroid state of 2 months. The duration of antithyroid drug therapy prior to cessation was shorter than international recommendations, indicating a significant reduction in time to treatment completion. Relapse occurred in 25.0% and was significantly associated with poor disease control (p = 0.014), while no significant associations were found with demographic or biochemical factors. Definitive therapy was required in 35.0%, with older age, growth stunting, and prior relapse identified as significant predictors (p <0.05). Conclusion Paediatric hyperthyroidism in this Malaysian cohort is predominantly due to Graves’ disease and frequently presents with both classical and atypical manifestations, which may delay diagnosis. Despite a high proportion of severe thyrotoxicosis at presentation, antithyroid drug therapy was effective, with a shorter duration to treatment cessation compared to international standards. Poor disease control emerged as the strongest predictor of relapse, while older age, growth stunting, and prior relapse predicted progression to definitive therapy. Early recognition and individualized management are essential to optimize outcomes. Larger multicentre studies are needed to inform national clinical practice guidelines.

Introduction: The global rise in paediatric obesity has led to an increasing burden of metabolic comorbidities, including metabolic dysfunction–associated steatotic liver disease (MASLD). Obstructive sleep apnea (OSA), characterized by chronic intermittent hypoxia, has been implicated in the pathogenesis of liver injury. This study aimed to evaluate the prevalence of MASLD and its association with OSA among children and adolescents in a tertiary centre. Methodology: A retrospective cross-sectional study was conducted involving children aged 6–15 years who were admitted for polysomnography at Sarawak General Hospital between 2024 and 2025. Clinical, biochemical, and lifestyle data were obtained from medical records and parental questionnaires. Hepatic steatosis was assessed using hepatobiliary ultrasound in a subset of patients. Results: A total of 132 children (mean age 10.8 ± 2.7 years; 87.5% male) were included. The median BMI SDS was 2.50 (IQR: 2.29– 2.93). The mean apnea–hypopnea index (AHI) was 12.0 ± 7.9, with 60% classified as severe OSA. Among the 16 children who underwent liver ultrasound, MASLD was identified in 81.2%, including five cases of grade 1 and eight cases of grade 2 steatosis. Liver transaminitis was present in six patients. Metabolic comorbidities were common, with 43.8% requiring metformin for insulin resistance or impaired glucose tolerance, and four patients requiring antihypertensive therapy. Unhealthy lifestyle behaviors were prevalent: 64.2% consumed sugary drinks ≥3 times weekly, 42.9% consumed fast food ≥3 times weekly, and only 24.3% reported daily fruit or vegetable intake. Physical inactivity (≤2 times/week) was observed in 71.4%, while 64.3% had screen time exceeding 2 hours daily. Conclusion Children and adolescents with moderate-to-severe OSA exhibit a high burden of metabolic dysfunction, including MASLD. The findings support a potential contributory role of OSA-related hypoxia in paediatric fatty liver disease and highlight the need for integrated screening and early intervention in this high-risk population.

Introduction: Endogenous Cushing syndrome is a rare manifestation of chronic cortisol excess. It may present with severe hypercortisolism complicated by life-threatening opportunistic infections. Surgical management of a cortisol-secreting tumor is the mainstay of therapy. However, when the source is not found or when surgery is not feasible, medical therapies may be employed for rapid control of hypercortisolism. CASE: A 13-year-old male presented with breathlessness for one day. He also had a cough associated with weight loss, weakness, and hallucinations for 1 month. On presentation, he was tachypneic and had moon facies, acne, fine moustache, limb wasting, and pigmented nail beds. He was also hypertensive and developed an episode of seizure during admission. Investigation results showed severe hypokalemia and lymphopenia. Radiological examination revealed pneumothorax with multiple lung cavitations and brain tuberculomas. Bronchoalveolar lavage (BAL) was positive for Aspergillus fumigatus. However, both BAL and CSF PCR and culture for TB were negative. Serum ACTH was 379 pg/mL (0–46), and morning serum cortisol was 2,948 nmol/L with loss of diurnal rhythm. His 24-hour urine cortisol was 14,252 nmol/24 hour (31.7–282). This is consistent with ACTH-dependent Cushing syndrome. He was started on anti-TB and anti-fungal treatment. Serum cortisol levels were persistently high while on high-dose intravenous dexamethasone treatment for TB meningitis. An MRI pituitary and a CT scan thorax, abdomen, and pelvis could not reveal an ACTH-secreting tumor source. Metyrapone was started and titrated upwards to control the hypercortisolism. Serum cortisol reduced to 200–300 nmol/L after 1 month, and 24-hour urinary cortisol was down to 22.4 nmol/24 hour after 4 months, requiring weaning of metyrapone doses. Conclusion Metyrapone is effective in the rapid control of severe hypercortisolism with life-threatening complications, as illustrated in this case. However, it warrants careful monitoring and titration.

Introduction: New-onset diabetes after transplantation (NODAT) is a clinically significant complication associated with adverse metabolic and graft outcomes and affects patients’ quality of life. Data in paediatric populations are limited. This case series describes the incidence, clinical characteristics, and early outcomes of NODAT in a paediatric kidney transplant cohort. Cases: Thirty patients (aged 5–17 years; 16 males, 14 females; 14 Malay, 15 Chinese, 1 Indian) underwent renal transplantation at Hospital Tunku Azizah between 2019 and 2025. NODAT was identified using standard diagnostic criteria and occurred in four patients (13.3%). Among patients who developed NODAT, three were Malay and one Chinese; all were aged 10–17 years, with a predominance of females (n = 3). All were non-obese (body mass index [BMI]: 11–21.4 kg/m²), and only one had a family history of type 2 diabetes mellitus. Underlying causes of ESRF in these patients included focal segmental glomerulosclerosis (FSGS, n = 2), CAKUT (n = 1), and unknown etiology (n = 1). Two patients received kidneys from living donors, and two from cadaveric donors. Two patients demonstrated reduced C-peptide levels, consistent with impaired insulin secretion. All patients received steroid induction and maintenance therapy alongside tacrolimus-based immunosuppression, with one patient also receiving everolimus. Two patients developed post-transplant CMV viremia, which has been associated with NODAT. The onset of NODAT was early, occurring within 2 weeks post-transplant in three patients and at 1 month in one patient. Insulin therapy achieved glycemic control in all cases. Two patients were able to discontinue insulin within 3–4 months, suggesting recovery of endogenous glycemic regulation, while the remaining two required ongoing insulin therapy. Conclusion NODAT affects a substantial proportion of paediatric kidney transplant recipients and may present despite the absence of conventional risk factors. Early surveillance is essential. The observed potential for insulin independence may indicate a reversible component of β-cell dysfunction, which warrants further investigation in larger cohorts.

Introduction: Childhood obesity is associated with significant metabolic morbidity, particularly insulin resistance (IR) and metabolic syndrome. Acanthosis nigricans (AN) is frequently observed in children with obesity and may represent a practical clinical marker of IR. This study evaluated the association between AN, IR, and metabolic complications in paediatric obesity. Methodology: A retrospective review was performed of 148 children (88 males, 60 females; median age 12 years) attending the Paediatric Obesity Clinic at Universiti Malaya Medical Centre. Data included anthropometry, AN grading, family history, HOMA-IR, and metabolic screening. Outcomes assessed were dyslipidemia, metabolic-associated fatty liver disease (MAFLD), hypertension, obstructive sleep apnea syndrome (OSAS), and glucose dysregulation. Comparisons were made between children with and without AN at baseline and over follow-up (median 2.4 years). Results: AN was present in 81.8% of patients, and 82.4% had central obesity. Increasing AN grade was significantly associated with higher BMI SDS and American Academy of Paediatrics obesity class (p <0.05). AN was more prevalent among Malay and Indian children and was associated with a family history of obesity (p <0.05). Baseline metabolic abnormalities were common, including dyslipidemia (high triglycerides 31.8%, low HDL 30.4%, high LDL 29.7%), MAFLD (23.6%), OSAS (31.1%), and glucose dysregulation (27.7%), with no significant difference between groups. During follow-up, children with AN and more severe obesity developed significantly more metabolic complications, particularly MAFLD and OSAS, with increased requirement for non-invasive ventilation (p <0.05). Higher HOMA-IR was associated with glucose dysregulation but was not independently associated with AN. Conclusion AN is strongly associated with greater adiposity and predicts the progression of metabolic complications in children with obesity. Routine assessment of AN may help identify high-risk patients who would benefit from early, intensive intervention to reduce long-term cardiometabolic morbidity
