Serum ferritin in pancreatic disease. An accurate test of malignancy?

Serum ferritin, described as increased in patients with pancreatic cancer, was studied in 109 subjects by an immunoradiometric technique in order to assess its reliability in detecting pancreatic malignancy. A significant increase of serum ferritin was found in pancreatic cancer as compared to controls (p less than 0.01), to calcifying (p less than 0.05), non-calcifying (p less than 0.05), and recurrent (p less than 0.01) chronic pancreatitis. Nevertheless, high levels of serum ferritin were found in 10 out of the 36 chronic pancreatitis patients and in 10 out of the 26 patients with non-pancreatic diseases, whilst values within the normal range were detected in 6 out of the 22 pancreatic cancer patients. These data suggest that serum ferritin, although frequently increased in pancreatic cancer, cannot be considered a marker of pancreatic malignancy.

Role of trypsin/creatinine clearance ratio in the differential diagnosis of chronic pancreatic disease.

Trypsin/creatinine clearance ratio--a recently proposed screening test for pancreatic cancer--was assessed in 45 subjects (17 control subjects, 15 patients with pancreatic cancer, and 13 with chronic pancreatitis). A statistically significant increase of the ratio was detected not only in pancreatic cancer, but also in chronic calcifying pancreatitis. Thus, the previously reported clinical usefulness of the test in pancreatic cancer diagnosis was not substantiated by the present data. Although not fully investigated as yet, reasons for an abnormal ratio are probably independent of the neoplastic or inflammatory nature of the pancreatic disease. Science renal enzyme excretion (alpha-glucosidase, gamma-glutamyltranspeptidase, leucine aminopeptidase) was not found to be invariably elevated when trypsin/creatinine clearance ratio was increased, tubular damage cannot be assumed as constituting the only reason for an altered clearance ratio.

[Use of the human umbilical vein as a vascular prosthesis. Experimental study].

The possible use of the human umbelical vein as a vascular transplant, following appropriate chemico-physical treatment is discussed. The properties of this new prosthesis have been studied on the basis, first, of physical and dynamic tests and, thereafter, following experimental intervention on 12 dogs in which a segment of the abdominal aorta was replaced. The animals were angiographed at varying times from the operation, up to a maximum of 8 months, and finally sacrificed for thorough histological study using various techniques.

[True aneurysms late complications of revascularization operations in the femoropopliteal tract].

The Authors report three cases of true aneurysms following arterial reconstructive surgery in the femoropopliteal tract. One time it was an autologous venous graft and two times of an endarterectomized artery. At surgery the suture line was intact; so the differential diagnosis with false aneurysms was made. This complication is very rare (less than 1%). That natural history and the treatment are reviewed.

Trypsin/creatinine clearance ratio and serum immunoreactive trypsin in digestive and pancreatic diseases.

The behavior of trypsin/creatinine clearance ratio (Ctr/Ccr) and serum immunoreactive trypsin (IRT) was evaluated in a total of 168 subjects with pancreatic cancer, chronic pancreatitis and non-pancreatic digestive diseases. Amylase/creatinine clearance ratio (Cam/Ccr) and serum amylase levels were also evaluated in order to establish their possible relationship with Ctr/Ccr and IRT values. Elevated Ctr/Ccr and IRT values were observed in several patients with pancreatic cancer and chronic pancreatitis. Abnormal IRT and Ctr/Ccr values were found in 28.2 and 4% of non-pancreatic digestive diseases, respectively. IRT and amylase serum levels showed consensual modifications, while Ctr/Ccr showed a behavior different from that of Cam/Ccr. Liver damage seems to play a role in increasing serum IRT levels of patients without pancreatic involvement, while the increased Ctr/Ccr seems to depend on other factors, for instance renal tubular dysfunction.

[Classification and seriousness of chronic venous diseases of the lower limbs. A concensus document].

It has been felt for a long time now that there is a need for a simple but complete classification of lower limb venous diseases, and many proposals concerning this matter have appeared in literature. The object of the new classification prepared at Maui, Hawaii, in 1994 is not only that of placing chronic venous diseases of the lower limbs under different profiles (clinical, etiological, anatomical, physiopathological), but also of supplying a numerical score concerning the seriousness of the disease.
