Mediastinal Synovial Sarcoma.

The mediastinum is an uncommon site of synovial sarcoma which is a rare soft tissue malignancy. An 18 year old boy was admitted for right sided chest pain since one year. Based on the CT scan chest findings, tru-cut biopsy of the mass was performed and histopathology initially reported as neurofibroma. The tumor was excised via posterolateral thoracotomy and excisional biopsy established the diagnosis of primary synovial sarcoma arising from the mediastinum. Patient was started on adjuvant chemotherapy at the oncologist tumor board’s recommendation and he received 6 cycles of adriamycin and ifosfamide. At last follow up he is free of tumor recurrence

Ionomic profiling of pericardial fluid in ischemic heart disease

Metals are essential cofactors that play a crucial role in heart function at the cell and tissue level. Information regarding the role of metals in the pericardial fluid and its ionome in ischemic heart disease (IHD) is limited. We aimed to determine the association of elements in pericardial fluid and serum samples of IHD patients and their correlation with systolic and diastolic function. IHD patients have been studied with systolic and diastolic dysfunction categorized on the basis of echocardiographic parameters. We measured concentrations of sixteen elements in the pericardial fluid and serum of 46 patients obtained during open heart surgery with IHD by ICP-MS. The levels of chromium and nickel in pericardial fluid were significantly higher as compared with serum samples of IHD patients (p \u3c 0.05). The chromium, nickel and manganese levels in pericardial fluid were lower in patients with ejection fraction (EF) \u3c 45% as compared to EF \u3e 45% (p \u3c 0.05). There was no significant difference in pericardial concentrations of elements in diastolic dysfunction grade 0–1 with 2 in IHD patients. We also found that decreased concentration of these elements in pericardial fluid is associated with decreased systolic function. These results suggest that pericardial fluid concentrations of these metals may reflect the extent of ischemic heart disease. These findings are hypothesis generating with regards to a role in the pathogenesis of the disorder

Understanding of metals dysregulation in patients with systolic and diastolic dysfunction in ischemic heart disease

Ischemic heart disease (IHD) is the leading cause of death and chronic disability in the world. IHD affects both the systolic and diastolic function of the heart which progressively leads to heart failure; a structural and functional impairment of filling or ejection of blood from the heart. In this study, the progression of systolic and diastolic dysfunction characterized according to their echocardiographic parameters including left ventricular ejection fraction (EF), grades of diastolic dysfunction and ratio between early mitral inflow velocity and mitral annular early diastolic velocity (E/e\u27), were correlated with differential regulation of various metals in patients sera samples (n = 62) using inductive coupled plasma-mass spectrometry (ICP-MS). Chromium, nickel and selenium were found significant (p \u3c 0.05) in patients having EF \u3c 45% compared with EF \u3e 45%. In patients with systolic dysfunction (EF \u3c 45%), the level of selenium was decreased while the level of chromium and nickel was increased compared to patients with EF \u3e 45%. Selenium level was also decreased significantly (p \u3c 0.05) in grade 1A and 2 patients that are considered as higher grades of diastole dysfunction in comparison to grade 0-1. Overall, selenium deficiency was identified in both systolic and diastolic dysfunctions of IHD patients corresponding to the progression of disease that could be related to many metabolic and translational pathways specifically which involve selenoproteins

Radial Artery Harvesting With Skin Bridge Technique Among Patients Undergoing Coronary Artery Bypass Grafting: An Approach For Developing Countries

The risk of wound dehiscence and sternal infections remains high after coronary artery bypass grafting, especially in patients with diabetes. Radial artery is a potential alternative which has shown good post-operative outcomes with least complications. Open and endoscopic techniques for harvesting have been used till now. We propose an interrupted or bridging technique, for harvesting the radial artery. This report describes 25 patients undergoing CABG, using radial artery graft, harvested via skin bridge technique, at South City Hospital, Karachi. It has a better cosmetic outcome, reduced postoperative pain, shortened hospital stay and increased level of satisfaction. The interrupted technique offers less invasive cost-effective approach compared to open and endoscopic techniques for radial artery harvesting
