Coronary artery disease in aortic surgery

The incidence of coronary artery disease in patients coming to aortic surgery and the impact of aggressive preoperative cardiac catheterization and myocardial revascularization was prospectively analyzed in 59 patients. Seventy-five percent of patients had at least one-vessel involvement, and 32% had three-vessel or left main involvement. Patients with electrocardiographic evidence of coronary artery disease had at least one-vessel involvement 84% of the time and three-vessel, left main involvement 36% of the time. Sixty-four percent of patients with no preoperative indications of coronary artery disease had at least one-vessel involvement and 29% had three-vessel, left main involvement. Resting (39 patients) and exercise multiple-gated acquisition scans (22 patients) did not predict the presence of coronary artery disease in patients without a history or electrocardiographic evidence of coronary artery disease. Myocardial revascularization was performed prior to aortic surgery in 17 patients (29%). The operative mortality was 3.7% with two patients dying from noncardiac-related complications. There were two additional deaths prior to aortic surgery with one patient dying during coronary artery bypass grafting, and one dying of aneurysm rupture prior to repair, making the overall mortality associated with this approach 7.4%. Preoperative cardiac catheterization and an aggressive approach toward coronary artery bypass grafting reduces the risk of cardiac complications in aortic surgery.     

Benign lymphoid hyperplasia manifesting as a cecal mass: Report of a case

Summary We have presented an unusual case of benign lymphoid hyperplasia, which manifested as a cecal deformity in a 15-year-old boy. The clinical manifestation may have been related to partial occlusion of the appendiceal orifice. In future cases of benign lymphoid hyperplasia, colonoscopy may be diagnostic, and if it is used for continuing observation, may avert unnecessary surgical procedures in children and young adults.     

Epidemiological features and specificities of HCV infection: a hospital-based cohort study in a university medical center of Calabria region

The epidemiological status of HCV in Europe, and in particular in Mediterranean countries, is continuously evolving. The genotype distribution is related to improvement of healthcare conditions, expansion of intravenous drug use and immigration. We review and characterize the epidemiology of the distribution of HCV genotypes within Calabria, an area of Southern Italy. We focus on the pattern of distinct HCV genotype changes over the last 16 years; particularly subtype 1b and genotype 4. We collected data by evaluating a hospital-based cohort of chronic hepatitis C patients; in addition, we report an update including new patients enrolled during last eight months.     

Intracortical haematogenous osteomyelitis

We present an unusual case of haematogenous osteomyelitis in the diaphysis of the tibia of an adult leading to a subacute presentation with an extracortical abscess. Fluid from the abscess grew methicillin resistant Staphylococcus aureus (MRSA) on culture; MRSA with the same antibiogram had been grown from the patient’s blood seven years earlier following a bowel resection. Drainage of the abscess and curettage of the bone lesion together with appropriate antibiotic therapy led to resolution of the osteomyelitis.     

Use of parenteral nutrition in treatment of advanced regional enteritis

Eight patients with advanced regional enteritis characterized by multiple areas of involvement, previous surgery (5 of 8), and failure on medical therapy (6 of 8) were placed on total parenteral nutrition for a period of 30 days. In eight of nine courses administered, definite improvement marked by weight gain, diminished pain, decreased diarrhea, and increased serum albumin was found. However, clinical remission was transient in seven of eight successful courses, indicating that parenteral nutrition is not a definitive form of therapy. However, the results suggest that parenteral nutrition may be useful in patients with regional enteritis to a) restore nutrition, b) induce remission, and c) prepare a debilitated patient for surgery. Additional experience is required to determine the efficacy of parenteral nutrition for therapy of fistulae caused by regional enteritis.
