Kidney transplantation from cadaveric donors unsuitable for other centers and older than 60 years of age.

INTRODUCTION: The demand for kidney transplants and the improvement in recipient outcomes over the last years have stimulated surgeons to expand the criteria for usable donor organs, by accepting older patients to expand their donor pool. We herein report our experience with kidney transplants from donors aged older than 60 years, who have been declined by other transplantation centers. PATIENTS AND METHODS: Sixty kidney transplantations were performed with grafts procured from donors aged older than 60 years. Forty-five patients received a single kidney graft (SKG) and 15 received a dual kidney graft (DKG). Mean donor age was 62 years for SKG and 64 years for DKG. Double kidney transplantations were performed with the ipsilateral allocation of both grafts. RESULTS: No primary graft nonfunction occurred. Delayed graft function was observed in 22 SKG (48.8%) and in 7 DKG (46.6%). Acute rejection rates were 9% for SKG and 0% for DKG. One-year patient survival rates were 95% and 100% for SKG and DKG, respectively. Mean serum creatinine levels at 1-year posttransplantation were 1.9 mg/dL for SKG and 1.3 mg/dL for DKG. There were no surgical postoperative complications and mortality. Death censored 1-year graft survival rate was 88% for SKG and 94% for DKG. CONCLUSIONS: Our experience with marginal donors who have been declined by other transplantation centers has demonstrated that such organs, with accurate selection criteria, could be safely allocated to elderly recipients with no increase in postoperative complications, guaranteeing satisfactory results in the short and medium term, allowing a significant improvement in the number of transplants.

Corpus callosal atrophy following closed head injury: detection with magnetic resonance imaging.

To investigate evidence for diffuse white matter injury and hemispheric disconnection sequelae after severe closed head injury (CHI), this study evaluates the degree of posttraumatic atrophy of the corpus callosum. Corpus callosal atrophy was quantitatively determined using a digitizer to measure sagittal magnetic resonance images of 32 patients with moderate-to-severe CHI and those of 31 control subjects of similar age. In the CHI patients, measurements were significantly reduced for the areas of the anterior four-fifths, the posterior one-fifth, and the total corpus callosum. Moreover, the minimum width of the callosal body was reduced in the CHI patients as compared to that of control individuals. Indices of corpus callosal atrophy were significantly correlated with the chronicity of injury and the degree of lateral ventricular enlargement. There was no difference in callosal measurements between men and women. Magnetic resonance imaging provides an in vivo determination of corpus callosal atrophy which may reflect the severity of diffuse axonal injury and predict the type and severity of hemispheric disconnection effects.

[Congenital hip dysplasia in Sicily]. / La displasia congenita dell'anca in Sicilia.

The Authors have analyzed the results of the ultrasound exams of the hips made in the Department of Pediatric Radiology, of the Catania University between 1993-1996 on 2000 little patients aged from 0 to 7 months. The aim of the examination was to define the frequency of the congenital dysplasia of the hip among the population of South-East Sicily because in literature there are no sure data. After a keen analysis of these data one can affirm that the incidence of the congenital dysplasia of the hip among the population of South-East Sicily is of 2.55% with the overwhelming prevalence in the females (M/F = 1/5). This percentage is thus comparable to the national one, and this allow us to confirm the great importance of the mass screening to prevent the congenital dysplasia of the hip even in Sicily.

Distal pancreatectomy with en bloc resection of the celiac axis for pancreatic adenocarcinoma.

Resection of celiac axis for gastric cancer was first performed by Appleby in 1953. Subsequently, Mayumi et al. and Kimura et al. adopted this approach for locally advanced adenocarcinoma of pancreatic body. We are here describing this technique in case of adenocarcinoma of pancreatic body with infiltration of celiac axis achieving also gastric preservation. Our patient presented with diabetes, back pain and weight loss. CT scan showed a 3 cm mass in the body of pancreas infiltrating the origin of celiac axis, causing obstructive atrophy of pancreatic tail. Bilirubin, transaminases, amylase and tumoral markers were in the normal range with the exception of CEA (34 ng/ml) and chromogranin (30 IU/l). Vascular reconstruction imaging indicated the feasibility of the procedure. Under intraoperative ultrasound guidance we clamped the common hepatic artery in order to check the gastric and hepatic blood flow. We then performed a distal pancreasectomy and splenectomy with "en bloc" resection of celiac axis and regional lymphadenectomy. Appleby operation can increase the resectability of locally advanced cancer of the body and tail of the pancreas and offers not only a better life quality for patients but also perfect pain relief. This technique demands a multidisciplinary approach with careful pre and intra operative vascular evaluation, which is mandatory in assessing candidacy for this procedure.
