Teenagers, archaeology and the Higher Education Field Academy 2005–11

The University of Cambridge Higher Education Field Academy (HEFA) (www.access.arch.cam. ac.uk/schools/hefa) involves teenagers in new archaeological excavations within English rural settlements. While the research aim is to reconstruct the development of today’s villages, hamlets and small towns, the social aim is to raise the educational aspirations of state-educated 13–15-year-olds and instil skills which will help them fulfil those ambitions. HEFA began in 2005, when it was funded by Aimhigher, itself set up in 2003 to increase the number of young people from lower socioeconomic groups and disadvantaged backgrounds attending university. HEFA was supported by English Heritage between 2009 and 2011. HEFA’s track record since 2005 has enabled it to weather policy U-turns and deep funding cuts, deliveringmore than 12,000 learning days to c 4,000 young people interested in subjects ranging from accountancy to zoology. Rigorous monitoring shows that more than 90% of HEFA participants rate it good or excellent and that after completing HEFA, 80% feel more positive about post-16 education, 85% have developed new skills and more than 90% plan to attend university, a rise of 25-60%

Temperature profile of ex-vivo organs during radio frequency thermal ablation by fiber Bragg gratings.

We report on the integration of fiber optic sensors with commercial medical instrumentation for temperature monitoring during radio frequency ablation for tumor treatment. A suitable configuration with five fiber Bragg grating sensors bonded to a bipolar radio frequency (RF) probe has been developed to monitor the area under treatment. A series of experiments were conducted on ex-vivo animal kidney and liver and the results confirm that we were able to make a multipoint measurement and to develop a real-time temperature profile of the area, with a temperature resolution of 0.1°C and a spatial resolution of 5 mm during a series of different and consecutive RF discharges

Total colectomy for cancer: analysis of factors linked to patients' age.

Total colectomy (TC) is a valid option for cancer treatment in selected cases. Emergency presentation, association to familial adenomatous polyposis (FAP) or intestinal bowel disease (IBD), hereditary non-polyposis cancer (HNPCC), and synchronous tumors are the common indications to TC for cancer. Despite potential high morbidity and mortality rates for worse general health conditions of the advanced age it has even suggested for elderly patients. We reviewed our experience to analyze the current role of TC comparing different results between young and elderly patients. During the period 1990-2012, 76 patients were operated on TC for cancer. Patients were divided in two groups according to the age [65 years old - group B (elderly)] and were compared their systemic and surgical complication, considering the presence of comorbidities, ASA score, lifestyle habits, elective or emergency presentation. Morbidity rate was 7.7% and 38.8% in young and elderly patients respectively.21 systemic complications (3 in group A and 18 in group B) occurred in 17 patients (22.36%) (with the coexistence of two complications in 4 patients belonging to the group B. There were 6 surgical complications (7.9%) (3 in group A and 3 in group B): anastomotic leakage 3, major wound infections 2, postoperative bleeding 1; no intra-abdominal abscess were observed. In 2 cases (2.6%) (1 anastomotic leak and 1 intra-abdominal postoperative hemorrhage) was needed a reoperation. We observed only 2 deaths in the elderly. High ASA score and emergency were associated with worst results. Systemic complications were more frequent in elderly patients cause of significant comorbidities, while the incidence of surgical complications was similar and according to literature. Besides the classic indications, it is a viable surgical option also in cancer associated with complicated diverticulitis. Our data show that TC is a safe and effective procedure providing good results even in elderly patients, when combined with a careful preoperative evaluation and age is not an absolute controindication to this procedur

Familial Polyposis Coli: The Management of Desmoid Tumor Bleeding

There is currently no standard treatment for desmoid tumors (DTs) associated with familial polyposis coli (FAP). Familial adenomatous polyposis in DT patients is sometimes a life-threatening condition

Gastroenterological complications in kidney transplant patients

AbstractKidney transplantation is the surgical operation by which one of the two original kidneys is replaced with another healthy one donated by a compatible individual. In most cases, donors are recently deceased. There is the possibility of withdrawing a kidney from a consenting living subject. Usually, living donors are direct family members, but they could be volunteers completely unrelated to the recipient. A much-feared complication in case of kidney transplantation is the appearance of infections. These tend to arise due to immune-suppressor drugs administered as anti-rejection therapy. In this review, we describe the gastrointestinal complications that can occur in subjects undergoing renal transplantation associated with secondary pathogenic microorganisms or due to mechanical injury during surgery or to metabolic or organic toxicity correlated to anti-rejection therapy. Some of these complications may compromise the quality of life or pose a significant risk of mortality; fortunately, many of them can be prevented and treated without the stopping the immunosuppression, thus avoiding the patient being exposed to the risk of rejection episodes

R0 surgical resection of giant dedifferentiated retroperitoneal liposarcomas in the COVID era with and without nephrectomy: A case report

: Retroperitoneal sarcomas (RPSs) are rare findings that can grow into large masses without eliciting severe symptoms. At present, surgical resection is the only radical therapy, whenever it can be performed with the aim to achieve a complete removal of the tumor. The present report describes two consecutive cases of RPSs that resulted in dedifferentiated liposarcomas (DDLPSs) and these patients underwent R0 surgical resection with and without a nephron-sparing procedure. The diagnostic workup, the surgical approach, the impact of late surgical management due to the COVID pandemic and the latest literature on the topic are discussed and analyzed. The patients, who refused to undergo any medical examination during the prior 2 years due to the COVID pandemic, were admitted to Federico II University Hospital (Naples, Italy) complaining about weight loss and general abdominal discomfort. In the first case, a primitive giant abdominal right neoplasm of retroperitoneal origin enveloping and medializing the right kidney was observed. The second patient had a similar primitive retroperitoneal giant left neoplasm, which did not affect the kidney. Given the characteristics of the masses and the absence of distant metastases, after a multidisciplinary discussion, radical surgical removal was carried out for both patients. The lesions appeared well-defined from the surrounding tissues, and markedly compressed all the adjacent organs, without signs of infiltration. In the first patient, the right kidney was surrounded and undetachable from the tumor and it was removed en bloc with the mass. The second patient benefited from a nephron-sparing resection, due to the existence of a clear cleavage plane. The postoperative courses were uneventful. Both the histological examinations were oriented towards a DDLPS and both patients benefited from adjuvant chemotherapy. In conclusion, the treatment of giant RPS is still challenging and requires multidisciplinary treatment as well as, when possible, radical surgical removal. The lack of tissue infiltration and the avoidance of excision or reconstruction of major organs (including the kidney) could lead to an easier postoperative course and an improved prognosis. When possible, surgical management of recurrences or incompletely resected masses must be pursued. Since the COVID pandemic caused limited medicalization of a number of population groups and delayed diagnosis of other oncologic diseases, an increased number of DDLPSs could be expected in the near future

Central Pancreatectomy to Treat a Giant Solid Pseudopapillary Tumor of the Pancreas - An Uncommon Surgical Procedure for a Rare Tumor: A Case Report and Review of the Literature

Context Solid pseudopapillary tumor is a rare tumor of the pancreas. Solid pseudopapillary tumor is nine times more frequent in the body and tail than in the head of the pancreas. It usually does not reach a large size. The majority of patients are young females and most of them are asymptomatic. Neoplasms of the midportion of the pancreas, not suitable for enucleation, can be treated with central pancreatectomy. The central pancreatectomy is commonly proposed for tumors that do not exceed 5 cm of dimension. Case report We report a case of seventeen-years-old woman who was admitted to our institution with abdominal pain and a palpable mass in the left hypochondrial area. US, CT and RMN scan revealed a giant (> 10 cm.) well-demarcated and encapsulated solid mass in the body of the pancreas, with a great amount of intralesional cystic-hemorrhagic component. The patient was treated by a variant of central pancreatectomy without splenectomy and pancreatic duct reconstruction. There was no metastatic disease in either the liver or peritoneum. The histological analysis identifies the tumor as a Solid pseudopapillary tumor of the pancreas. Fifteen years' follow-up period showed no recurrence. Conclusions Solid pseudopapillary tumor of the pancreas behaves like a potentially malignant tumor and has good prognosis. Surgical resection is dictated by tumor location and is the treatment of choice. The increasing interest in parenchyma-sparing pancreatic surgery has found large application in treatment of Solid pseudopapillary tumor, with the aim of preserving exocrine and endocrine pancreatic function, and achieving a better quality of life after surgery. Considering the low malignant potential, the central pancreatectomy can be considered an excellent therapeutic strategy for the treatment of this type of tumor also when they have giant dimensions and are localized in the central-pancreatic portion
