AIM (18)Fluorodeoxyglucose ((18)FDG) positron emission tomography/computed tomography (PET/CT) is an established part of staging in a wide variety of malignancies. Incidental abnormal uptake of (18)FDG of unknown significance is frequently encountered. Therefore, we investigated patients with abnormal colonic uptake of (18)FDG, determined by PET/CT images,(More)
INTRODUCTION Low pelvic anastomoses are associated with a high leak rate. Therefore, defunctioning loop ileostomies are being increasingly fashioned to protect against the consequences of a leak. However, the reported complication rates of such stoma creation and closure is between 5.7-69%. AIMS To determine the outcome associated with construction and(More)
INTRODUCTION Parastomal hernia is a common complication of stoma construction. Although the majority of patients are asymptomatic, about 10% require surgical correction. AIMS We describe a new surgical approach for the repair of parastomal hernias, which avoids both the need for laparotomy and stoma mobilization. PATIENTS AND METHODS Nine patients (4(More)
PURPOSE The management of high fistula-in-ano presents a difficult surgical challenge. Laying open of high transsphincteric, intersphincteric, and suprasphincteric fistulas is associated with incontinence. Mucosal advancement flap can be technically difficult and is associated with ectropion and incontinence. We report a new technique for the treatment of(More)
PURPOSE Glyceryl trinitrate ointment applied to the anal verge lowers anal resting pressure, but its duration of action is uncertain. This study investigated the effect and duration of action of 0.2 percent glyceryl trinitrate on anal resting pressure and hemodynamic parameters. METHODS A total of 15 volunteers, 9 male, with a median age of 30 (range,(More)
Thirty-five patients received 105AD7 human anti-idiotype vaccination prior to surgery for colorectal carcinoma. Patients were immunized before and also received one to two immunizations after surgical resection of their colorectal cancer. The vaccine was well tolerated with no associated toxicity. Lymphocytic infiltration within the resected tumors was(More)
Clinical profiles, serological markers, and antibody responses to antigens of hepatitis B virus (HBV) were studied in patients with fulminant viral hepatitis. Whereas hepatitis A and B were found to be uncommon causes (6.9% and 12.2%, respectively), non-A, non-B (NANB) hepatitis was found to be the most common cause of fulminant hepatitis (80.9%). As(More)
Eighty-three patients with rheumatoid arthritis (RA) were investigated for HLA-DQ and DR locus restriction fragment length polymorphisms (RFLP). Of the 83 patients, 61 (73%) possessed the DR4 allele and within this group we have investigated the relative frequencies of two DQ beta gene variants of DQw3, DQw7 and DQw8, one of which we had previously found to(More)
The functional end point of immunotherapy is to induce tumor regression. Because immune effector mechanisms usually result in apoptosis, the aim of this study was to determine whether measurement of tumor apoptosis ex vivo is a good end point to evaluate the efficacy of cancer vaccines. A prototype vaccine, 105AD7, was administered to colorectal cancer(More)
