Introduction: Pheochromocytoma is a catecholamine-secreting adrenal tumor associated with major perioperative hemodynamic instability. When concurrent major pelvic pathology requires surgery, operative planning becomes particularly challenging. We describe the successful single-stage management of pheochromocytoma and a giant uterine fibroid, highlighting the importance of multidisciplinary coordination and perioperative optimization. Case: A 49-year-old female with symptomatic uterine fibroid was found to have proliferative endometrium on a pipelle biopsy. Computed tomography (CT) abdomen incidentally detected a right adrenal mass alongside a large posterior uterine fibroid (11.9 × 17.4 × 14.6 cm). CT adrenal protocol demonstrated a heterogeneously enhancing right adrenal mass (6.9 × 6.9 × 9.6 cm) with high unenhanced attenuation. Biochemical evaluation revealed markedly elevated 24-hour urinary metanephrine (4.7× upper limit) and normetanephrine (2.4× upper limit). Following multidisciplinary discussions, a single-stage surgical approach was planned after careful assessment of feasibility and perioperative risk in view of the uncertain malignant potential of the pelvic mass and to minimize repeated exposure to anesthesia. Preoperative optimization included transitioning from terazosin to phenoxybenzamine, with subsequent addition of bisoprolol for hemodynamic control. The operative strategy prioritized pheochromocytoma resection first, given its potential for significant hemodynamic instability. Progression to hysterectomy was contingent upon achieving adequate intraoperative hemodynamic stability following adrenalectomy, with continuous reassessment by the anesthetic and surgical teams. Right adrenalectomy was performed first, followed by total abdominal hysterectomy with bilateral salpingooophorectomy. Significant hemodynamic lability occurred during tumor manipulation, with hypertensive surges managed using sodium nitroprusside and remifentanil infusions. Following adrenal vein ligation and tumor removal, hypotension was managed with noradrenaline and additional adrenaline support as required. Total operative time was approximately 6 hours. Postoperatively, transient noradrenaline support was required but was rapidly weaned as hemodynamic stability was achieved. Conclusion Single-stage adrenalectomy and major pelvic surgery can be safely performed in selected patients with pheochromocytoma when guided by meticulous preoperative optimization, clear intraoperative sequencing, and close multidisciplinary coordination.

Introduction: Giant parathyroid adenomas (GPAs), defined as lesions >3.5 g, are rare. Their size, biochemical severity, and compressive features often mimic carcinoma, creating diagnostic and surgical challenges. Case: A 33-year-old female was incidentally found to have hypercalcemia during evaluation after her newborn developed severe hypocalcemic seizures requiring NICU admission. Maternal calcium was 2.95 mmol/L with hypophosphatemia. Subsequent reviews showed persistent hypercalcemia (3.15–3.3 mmol/L), hypophosphatemia (0.32– 0.51 mmol/L), and markedly elevated intact parathyroid hormone (85–96 pmol/L). She had vitamin D deficiency, very high alkaline phosphatase (1,329 U/L), and progressive bone pain with reduced mobility. Bone mineral density revealed Z scores of −2.9 (hip) and −3.3 (lumbar spine). Multiphase computed tomography demonstrated a multilobulated 6.9 cm mass extending from C5 to T2, compressing the esophagus and raising suspicion for carcinoma. Endoscopic evaluation excluded mucosal invasion. She underwent en bloc left inferior parathyroidectomy with hemithyroidectomy. Intraoperative parathyroid hormone fell from 41.7 to 13.4 pmol/L, confirming complete excision. The gland measured 65 × 20 × 15 mm and weighed 18.4 g. Histopathology revealed a hypercellular parathyroid tumor with endocrine atypia but no invasion, consistent with a giant adenoma. Postoperatively, calcium was initially stable (1.99 mmol/L at discharge) but fell to 1.68–1.82 mmol/L at 2 weeks despite high-dose supplementation. Hypocalcemia persisted for 6 weeks, consistent with delayed hungry bone syndrome, likely precipitated by preoperative vitamin D deficiency, markedly elevated alkaline phosphatase, and low bone mineral density. With intensive supplementation, calcium gradually stabilized, and symptoms improved. Conclusion GPAs can closely mimic carcinoma, with endocrine atypia complicating histopathological interpretation. This case illustrates both diagnostic overlap and the unusual, delayed onset of hungry bone syndrome, emphasizing the need for preoperative risk assessment, correction of metabolic deficiencies, and extended postoperative monitoring. Rare presentations such as delayed hungry bone syndrome refine management strategies and improve outcomes in primary hyperparathyroidism.

Introduction: Association studies between single nucleotide polymorphisms (SNPs) and type 2 diabetes mellitus (T2DM) have been abundant. However, there are limited reports on copy number variations (CNVs) of beta-defensins (DEFB) gene in relation to T2DM. In this study, DEFB copy numbers were quantified in T2DM with nephropathy, T2DM without nephropathy and non-diabetic control groups to investigate its influence in chronic inflammation in Malaysian individuals. Methods: DEFB copy number in Malaysian individuals were quantified by using paralogue ratio tests (PRT) which allow direct quantification of gene copy number by using PRT107A and HSPD21 PRT primers. The copy number generated was then validated from insertion/deletion ratio measurement 5DEL (rs5889219) and two microsatellite analyses (EPEV-1 and EPEV-3). Results: DEFB copy number was found extending from 2 to 8 copies in the non-diabetic group (n=146), while in T2DM group (n=392), copy numbers were more extensive, ranging between 1 and 12 copies; with 1, 10 and 12 copies detected in T2DM with nephropathy group (n=202). Statistically, there is no significant difference in DEFB copy number between T2DM and the non-diabetic group (p=0.209) as well as between diabetic nephropathy and without nephropathy of the T2DM group (p=0.522). However, significant white blood cell (WBC) count was found between T2DM groups with and without diabetic nephropathy (p=0.000). Conclusion: Extreme DEFB copy numbers in T2DM with nephropathy group suggest future studies with bigger sample size are necessary to elucidate the true impact of CNVs of DEFB gene in promoting early onset of nephropathy in T2DM.

Diabetes in pregnancy is associated with risks to the woman and her developing fetus. Management of the condition at the primary care level includes pre-conception care, screening, diagnosis, as well as antenatal and postpartum care. A multidisciplinary approach is essential in ensuring its holistic management.
