BACKGROUND The aim of the study is to analyze pancreatic metastases and their clinical, radiological, therapeutic and prognostic features. METHODS Three cases of pancreatic metastases observed and a world literature review of 333 cases were recorded. RESULTS Pancreatic metastases are due more frequently to renal cell carcinoma; they are usually(More)
The ANTARES collaboration is building a deep sea neutrino telescope in the Mediterranean Sea. This detector will cover a sensitive area of typically 0:1 km and will be equipped with about 1000 optical modules. Each of these optical modules consists of a large area photomultiplier and its associated electronics housed in a pressure resistant glass sphere.(More)
Many galactic and extragalactic astrophysical sources are currently considered promising candidates as high-energy neutrino emitters. Astrophysical neutrinos can be detected as upward-going muons produced in charged-current interactions with the medium surrounding the detector. The expected neutrino fluxes from various models start to dominate on the(More)
The final analysis of atmospheric neutrino events collected with theMACROdetector is presented. Three different classes of events, generated by neutrinos in different energy ranges, are studied looking at rates, angular distributions and estimated energies. The results are consistent for all the subsamples and indicate a flux deficit that depends on energy(More)
OBJECTIVE Pancreatic laparoscopic surgery represents one of the most discussed and demanding fields in surgery. Total pancreatectomy is considered to a viable option for treating both benign and malignant pathologies of the pancreas and, thanks to the introduction of laparoscopic techniques for pancreatic resections into clinical practice, it can be(More)
Using data collected by the MACRO experiment from 1989 to the end of its operations in 2000, we have studied in the underground muon flux the shadowing effects due to both the Moon and the Sun. We have observed the shadow cast by the Moon at its apparent position with a significance of 6.5 σ. The Moon shadowing effect has been used to verify the pointing(More)

The improvement of results and patients quality life is the aim of surgical technique. Mini-laparoscopic cholecystectomy brings not only to a better cosmetic results, but also to a decrease of post operative pain, analgesic use, hospital stay and an early return to normal activities. In this study, Authors report their own experience about mini-laparoscopic(More)
Mesenteric fibromatosis is a rare benign mesenteric tumour, characterised by infiltrative growth and high rates of recurrence. Histological examination is the only diagnostic procedure capable of ruling out a malignant mesenteric neoplasm. It is not always possible to perform a radical removal of the tumour mass because it may have infiltrated important(More)
