BACKGROUND The management of gallstone ileus is controversial. This study compared the results of simple enterolithotomy with those of enterolithotomy, cholecystectomy and fistula closure. METHODS A retrospective analysis was made of 25 patients with a mean age of 75 (range 55-84) years. Enterolithotomy was performed in 16 patients (group 1) and(More)
CONTEXT Osteoporosis has a significant genetic component. The aromatase-dependent conversion of androgenic precursors is the main source of estrogens in postmenopausal women. OBJECTIVE The objective of the investigation was to study the relationship of a set of single nucleotide polymorphisms (SNPs) of the aromatase gene with osteoporosis and determine(More)
BACKGROUND We review our experience in patients who required surgical correction of tricuspid valve disease with concomitant disease of the mitral or aortic valve, or both, operated on between 1987 and 1999. METHODS We studied 232 consecutive patients (mean age, 59.8 years) followed for a mean of 6.8 years (range, 2 to 12 years). All patients were(More)
During the 1970s, initial clinical experience with bioprostheses determined their worldwide use. However, bioprosthetic reoperation (BPR) is now common, particularly in groups with extensive implantation of these valve substitutes. From January 1980 to December 1989, a total of 470 patients had a total of 618 reoperations for bioprosthetic dysfunction and(More)
OBJECTIVE The objective was to analyze the short- and long-term results of patients with previous tricuspid valve repair who had valve dysfunction and required cardiac reoperations. METHODS Between 1976 and 2002, 74 patients with a mean age of 53.8 +/- 12.2 years underwent valve reoperations for dysfunction of previous tricuspid valve repair. Mitral and(More)
OBJECTIVE Mitral regurgitation due to prolapse of the mitral leaflets frequently compromises annuloplasty repair procedures. We present a new annuloplasty ring that overcomes this difficulty, preventing displacement of the leaflets into the atrium. METHODS The 'Valve Racket' is a prosthetic ring transformed into a racket by means of handmade mesh using(More)
Glucagonoma is a rare pancreatic tumor, that gives a characteristic clinical syndrome. In this report we describe the case of a 27 year old woman whose only clinical manifestations were a facial erythema and a palpable abdominal mass. Surgical removal of the tumor resulted in elimination of the clinical symptoms. Immunohistochemical findings were consistent(More)
The coexistence of a pancreatic papillary cystic tumor with hairy cell leukemia is reported. To the best of our knowledge this association has never been published. A 41-year-old man diagnosed with hairy cell leukemia developed a second malignancy that corresponded to a papillary cystic pancreatic tumor. The patient underwent splenectomy and a tumoral(More)
