High recipient age, BMI > 30, hyper trigelyceridaemia, previous transplantation, CMV infection and DGF are shown to be risk factors for TRAS.

BackgroundBasal cell carcinoma (BCC) is the most common type of human cancer. Despite the high prevalence of these tumors, there is a lack of reliable epidemiological data in some regions including Iran.ObjectiveTo assess the relationship between BCC subtypes and anatomical distribution in the Iranian population.MethodsThere were 876 patients with a single BCC enrolled in this study (March 2007 to March 2010; Razi Dermatology Center, Tehran, Iran).ResultsAmong 876 patients, 544 were males and 332 females. Of the lesions, 43% were nodular, 32.4% mixed type, 3% superficial and rest of other subtypes. In the lesion location, 58.2% were on the face, 29.2% on scalp, 6.2% on ears, 2.3% on neck, 1.7% on trunk and 1.3% on the extremities. There was no significant difference between male and female in the BCC subtypes, but anatomical distribution of the tumor was different (p=0.002). Most of the trunk-arising BCCs were superficial, and most of the facial BCCs were nodular subtype. Also, most of the BCC subtypes occurred in patients between 40 to 80 years old and mostly on the face and scalp (p=0.04). However, superficial BCCs mostly occurred in younger patients over others (p=0.001).ConclusionSubtype is associated with a site, independent of gender or age. Also BCCs occurring on the trunk are mostly of the superficial subtype.

Aneurysm of a saphenous vein graft (SVG) is a rare but fatal complication of coronary artery bypass graft (CABG) surgery. The development of SVG aneurysms appears usually about 10-20 years after the operation at an estimated rate of <1%. A 68-year-old male was referred to the emergency department after frequent episodes of dyspnea, chest pain and hemoptysis. He previously had CABG surgery one year before. The physical examination was normal. Chest radiogram showed a left pulmonary midzone mass. CT-angiogram demonstrated a large aortic pseudoaneurysm (6.36 x 6.06 cm) in the middle part of the ascending aorta. After sternotomy, the ascending aorta above sinotubular junction near the origin of brachiocephalic artery was resected and replaced with a tube graft. The patient was transferred to ICU with stable hemodynamic status. SVG aneurysm should be considered while encountering mediastinal mass or undiagnosed cardiopulmonary symptoms in patients with a previous history of CABG because of its rarity and overlap of symptoms with other thoracic, pulmonary, and cardiac diseases. Surgery seems to be the treatment of choice to reduce the risk of rupture and embolism.
