ABSTRACT
@#Thyroid hormone plays an important role in cardiovascular function. Pericardial effusions are commonly seen in cases of severe hypothyroidism. However, large to massive pericardial effusions with cardiac tamponade are exceptionally rare. Herein, we present two cases of severe hypothyroidism with massive pericardial effusion. Our first case demonstrates that a patient with large pericardial effusion can be managed conservatively with aggressive thyroid hormone replacement therapy. In our second case, pericardiocentesis was performed in addition to thyroid hormone replacement therapy as the underlying aetiology of effusion could not be reasonably limited to hypothyroidism. These two cases served to highlight and demonstrate rapid normalisation of thyroid function test by using aggressive oral thyroid hormone replacement therapy using liothyronine, in combination with levothyroxine, which led to resolution of pericardial effusion and prevent its re-accumulation.

Objective@#To evaluate the effect of adding DPP4 inhibitor (DPP4-i) on glycemic variability (GV) in patients with type 2 diabetes mellitus (T2DM) treated with premixed human insulin (MHI).@*Methodology@#We conducted a prospective study in patients with T2DM on twice-daily MHI with or without metformin therapy. Blinded continuous glucose monitoring was performed at baseline and following 6 weeks of Vildagliptin therapy.@*Results@#Twelve patients with mean (SD) age of 55.8 (13.1) years and duration of disease of 14.0 (6.6) years were recruited. The addition of Vildagliptin significantly reduced GV indices (mmol/L): SD from 2.73 (IQR 2.12-3.66) to 2.11 (1.76-2.55), p=0.015; mean amplitude of glycemic excursions (MAGE) 6.94(2.61) to 5.72 (1.87), p=0.018 and CV 34.05 (8.76) to 28.19 (5.36), p=0.010. In addition, % time in range (3.9-10 mmol/l) improved from 61.17 (20.50) to 79.67 (15.33)%, p=0.001; % time above range reduced from 32.92 (23.99) to 18.50 (15.62)%, p=0.016; with reduction in AUC for hyperglycemia from 1.24 (1.31) to 0.47 (0.71) mmol/day, p=0.015. Hypoglycemic events were infrequent and the reduction in time below range and AUC for hypoglycemia did not reach statistical significance.@*Conclusion@#The addition of DPP4-I to commonly prescribed twice-daily MHI in patients with T2DM improves GV and warrants further exploration.

Diabetes Mellitus, Type 2ABSTRACT
We report a case of occult primary spontaneous pneumothorax in a 30 years-old woman. She developed symptoms and signs that were suggestive of pneumothorax. However, chest radiograph failed to reveal pneumothorax. Therefore, we proceeded with computed tomography (CT) thorax which revealed significantly moderate right pneumothorax. The diagnostic approach and the management of this case are discussed.
ABSTRACT
@#For ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS), when surgery is not feasible, or in cases of severe biochemical disturbances, immunosuppression or mental instability, medical therapy with agents such as etomidate is indicated. We present our experience in using etomidate for a 41-year old female with EAS secondary to a malignant mediastinal paraganglioma. We were able to demonstrate that etomidate can be used effectively to control severe hypercortisolism in a lower dose than previously described.

We report a case of a 54-year-old man with severe HTG which did not respond to conventional anti lipid therapies. He was treated with intravenous insulin and concurrent dextrose infusions which led to a dramatic reduction in serum triglyceride levels.

HypertriglyceridemiaABSTRACT
In pregnancy, the diagnosis of primary hyperparathyroidism (PHP) may be delayed due to physiological changes that occur during this period. The maternal related complications of PHP during pregnancy has been reported to be as high as 67%, whilst fetal complications up to 80% of cases.1 The therapeutic gold standard and definitive treatment for PHP in pregnancy is minimally invasive parathyroidectomy in the second trimester. We report a case of a 22-year old primidgravida who underwent parathyroidectomy in the third trimester of her pregnancy for PHP with persistent hypercalcemia. She was also found to have Vitamin D deficiency which probably led to secondary hyperparathyroidism and made her hypercalcemia more apparent during pregnancy.
