Berm design to reduce risks of catastrophic slope failures at solid waste disposal sites.

Existing waste disposal sites are being strained by exceeding their volumetric capacities because of exponentially increasing rates of municipal solid waste generation worldwide, especially in densely populated metropolises. Over the past 40 years, six well-documented and analyzed disposal sites experienced catastrophic failure. This research presents a novel analysis and design method for implementation of a series of in-situ earth berms to slow down the movement of waste material flow following a catastrophic failure.

Virtual ileostomy following rectal cancer surgery: a good tool to avoid unusefull stomas?

Background/aims: Anastomotic leak is a life threatening complication following surgery for rectal cancer below peritoneal reflection. Colostomy or ileostomy following colorectal or coloanal anastomosis protect the patients from general peritonitis or sepsis secondary to anastomotic leak.

Methodology: In this paper the experience of the last 100 cases of rectal cancer below the peritoneal reflection treated from 2004 to 2010 was reviewed.

Expression of Medicago truncatula genes responsive to nitric oxide in pathogenic and symbiotic conditions.

Nitric oxide (NO) is involved in diverse physiological processes in plants, including growth, development, response to pathogens, and interactions with beneficial microorganisms. In this work, a dedicated microarray representing the widest database available of NO-related transcripts in plants has been produced with 999 genes identified by a cDNA amplified fragment length polymorphism analysis as modulated in Medicago truncatula roots treated with two NO donors. The microarray then was used to monitor the expression of NO-responsive genes in M.

Glutathione synthesis is regulated by nitric oxide in Medicago truncatula roots.

Glutathione (GSH) is one of the main antioxidants in plants. Legumes have the specificity to produce a GSH homolog, homoglutathione (hGSH). We have investigated the regulation of GSH and hGSH synthesis by nitric oxide (NO) in Medicago truncatula roots.

The sentinel lymph node in papillary cancer of the thyroid including histological subtype.

Background: The aim of this work was to reveal through sentinel node study the intraoperative presence of preoperatively undetected pathological lymph nodes.

Materials And Methods: At the Surgical Science Department of La Sapienza University of Rome The Authors studied from January 2003 to June 2004 18 patients with papillary carcinoma of the thyroid, who presented no clinical evidence of lymph node metastasis; they performed a total thyroidectomy in all cases, removing and histologically examining all lymph nodes of the upper anterior mediastinum. Where negative they were then subjected to immunohistochemical analysis with Pan Cytokeratin.

Bilateral synchronous parathyroid carcinoma in a patient on long-term hemodialysis: presentation of a rare clinical case and review literature.

Synchronous bilateral carcinoma of the parathyroid in subjects undergoing prolonged hemodialysis is an extremely rare pathology. After observing a clinical case, we reviewed the literature on parathyroid carcinoma. We describe the clinical case of a 61-year-old man with synchronous bilateral carcinoma of the parathyroid.

Prognostic significance of the age factor in the thyroid cancer: statistical analysis.

Background And Objectives: To determine whether thyroid carcinoma in elderly patients presents any peculiar characteristics, whether the greater biological aggressiveness of the neoplasm modifies the surgical treatment selected, and whether age greater than 70 years represents an independent prognostic factor.

Methods: Retrospective analysis of case histories from the Department of Surgery of "La Sapienza" University of Rome; 403 patients subjected to total thyroidectomy between 1993 and 1999, with a minimum follow-up period of 3 years subdivided into three groups: group I (patients aged between 20 and 50 years), group II (patients aged between 51 and 70 years) and group III (patients aged >70 years). The surgical and postoperative treatment is uniform in all study groups.

Epithelioid haemangioendothelioma of the parotid salivary gland: a case report.

Haemangioendothelioma is a vascular tumour characterised by the proliferation of endothelial cells with an epithelioid appearance. The behaviour of this neoplasm is intermediate between haemangioma and angiosarcoma. It may be localised in a wide range of sites, with a preference for soft and bone tissue.

Synchronous bilateral renal tumour: a case report.

We report a case of synchronous bilateral renal carcinoma treated by partial nephrectomy on the right and total nephrectomy on the left. Follow-up at 42 months after surgery showed no recurrence of the disease. The increasing use of diagnostic imaging techniques such as ultrasound tomography, computerised tomography and nuclear magnetic resonance now allows even small-sized renal formations to be identified.

Parotid gland tumours. Our experience and a review of the literature.

In this study the authors examine the experience of their department in treating parotid tumours, evaluating in particular the various surgical techniques as a function of the prognosis and the incidence of relapses. Between 1 January 1970 and 31 December 2002, 336 patients with parotid tumour were observed in the Department of Surgical Sciences of "La Sapienza" University in Rome. Two hundred and thirty-nine patients with benign tumours and 65 with malignant tumours were analysed.
