Hypercalcaemic Paraneoplastic Syndrome in a Young Woman with Malignant Phyllodes of the Breast: A Case Report Paraneoplastic syndromes, though uncommon, present systemic effects secondary to primary malignancies or metastases. We presented a case of a 25-year-old nullipara with a left breast malignant phyllodes. Pre-operative investigations revealed hypercalcaemia. Her staging computed tomography scan did not demonstrate any enlarged parathyroid gland. Her serum intact parathyroid hormone level was not raised. After correction with saline hydration, she underwent a left mastectomy, axillary dissection and a supercharged bipedicle TRAM flap. The following day, due to flap congestion, she underwent flap exploration but unfortunately, the flap necrosed. She required temporary coverage with a split-skin graft to allow her post operative sepsis to resolve. She underwent a delayed extended latissimus dorsi myocutaneous pedicled flap for chest wall closure. The cause of hypercalcemia was attributed to be a paraneoplastic syndrome which has not been reported previously in a malignant phyllodes tumor. The hypercalcaemia is postulated to have caused the thrombosis leading to flap failure

Introduction: Vascular dysregulation is postulated to be involved in the pathogenesis of primary open angle glaucoma (POAG). Systemic arterial stiffness may accelerate the pre-existing damage. The purpose of this study was to determine the association of arterial stiffness with severity and progression of visual field in Malay patients with POAG. Methods: A cross-sectional study was conducted with 55 patients with POAG and 55 age- and sex-matched control subjects. The patients with POAG were further divided in accordance with their Advanced Glaucoma Intervention Study (AGIS) scores on their visual fields (VFs) (mild in 23 patients, moderate in 18, and severe in 14). Progression was defined as the worsening of the VF defect quantified as an increase in AGIS score of 4 points from the baseline. Arterial stiffness was measured using SphygmoCor and quantified as pulse wave analysis (PWA) and pulse wave velocity (PWV). Results: No significant differences in PWA and PWV were found between the patients with POAG and the control subjects (p=0.333 and p=0.443, respectively). The mean follow-up duration for the patients with POAG was 4.7±3.1 years. PWA and PWV showed no significant association with POAG severity after the confounding factors were controlled for. Ten patients with progression of VF were identified. In the analysis of covariance, a significantly higher PWV was found in the patients with disease progression (p=0.036). Conclusion: VF severity and progression were not associated with systemic arterial stiffness. The probable reason is that other factors affecting retinal microcirculation may play a larger role in the severity and progression of POAG.
