Usefulness of Transesophageal Echocardiography in Diagnosing and Guiding Correct Placement of a Right Ventricular Assist Device Malpositioned in the Left Atrium

In this report, we describe how transesophageal echocardiography was used not only to diagnose incorrect cannula position of a right ventricular assist device in the left atrium through a patent foramen ovale, but also to guide and to confirm correct cannula placement.     

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.     

The colitis of Behcet's disease: A separate entity?

Summary An additional case of Behcet's disease with colonic involvement has been presented. This association is rare, as only 13 prior cases with adequate data were available for comparison. Controversy exists as to whether these cases represented true involvement of the colon by Behcet's disease, coincidental inflammatory bowel disease and Behcet's disease, or merely autoimmune phenomena associated with inflammatory bowel disease. Unusual colonoscopic lesions noted in our patient and other features enumerated in the text suggested to us that at least some of these cases represented primary Behcet's disease involving the colon.     

Gastric blood flow

Summary In summary, the vascular bed of the stomach is an area of great potential importance to both gastric and vascular physiologists. There are available many technics for its investigation. Simultaneous study of both hemodynamic and secretory phenomena can be conducted on the stomach. In the next few years information concerning the circulation of the stomach may help elucidate problems in the physiology and pathology of gastric secretion. Hightower observed recently: The topic of visceral circulation, particularly as it pertains to the digestive tract, has not been commented upon in recent...Reviews of Physiology. This subject has become increasingly important in the past few years and is an area with which physiologists interested in the digestive system will become more and more concerned.³³
