Combined hepatectomy and radiofrequency ablation for multifocal hepatocellular carcinoma: a case report
2009
Introduction: At the present time, the best possible choice for the local management of a multifocal hepatocellular carcinoma (HCC) developing on liver cirrhosis is multimodal treatment of the disease. Combined approach based on simultaneous radiofrequency ablation (RFA) together with limited surgical resection represents a valid choice of treatment. Case presentation: A 75-year-old white female patient affected of HCV-associated cirrhosis in BChild-Pugh’s functional class A5, developed a bifocal HCC. The patient had undergone a limited surgical resection together with simultaneous RFA, without intraoperative and postoperative surgical complications. At 36 months after surgery, still shows …

Characterization of Human γδ T Lymphocytes Infiltrating Primary Malignant Melanomas
2012
T lymphocytes are often induced naturally in melanoma patients and infiltrate tumors. Given that gamma delta T cells mediate antigen-specific killing of tumor cells, we studied the representation and the in vitro cytokine production and cytotoxic activity of tumor infiltrating gamma delta T cells from 74 patients with primary melanoma. We found that gamma delta T cells represent the major lymphocyte population infiltrating melanoma, and both V delta 1(+) and V delta 2(+) cells are involved. The majority of melanoma-infiltrating gamma delta cells showed effector memory and terminally-differentiated phenotypes and, accordingly, polyclonal gamma delta T cell lines obtained from tumor-infiltrat…
Skewed Differentiation of Circulating Vγ9Vδ2 T Lymphocytes in Melanoma and Impact on Clinical Outcome
2016
OBJECTIVE:The aim of this study was to evaluate over time circulating γδ T lymphocytes in melanoma patients in terms of frequency, effector functions, and relationship with clinical stage and evolution, by comparing preoperative values to those obtained at a mean follow-up of 36 months or in the event of recurrence or disease progression, and to those of healthy controls. Also, we correlated the presence of tumor-infiltrating γδ T lymphocytes with clinical evolution of melanoma. RESULTS:Mean frequencies of circulating γδ T cells before and after melanoma removal were very similar and comparable to healthy subjects, but patients who progressed to stage III or IV showed a significantly decrea…
Neurosurgical Odyssey: Case of Anaplastic Meningiomatosis.
2017
According to the World Health Organization grading, meningiomas are classified as grade I (benign), grade II (atypical), and grade III (anaplastic). Most of them (81%) are benign, 15% are atypical, and 4% are anaplastic. Metastasis is a rare event in meningiomas, occurring in <1% of cases. In most types of tumors, distant metastasis is an incontrovertible indication of malignancy. This is not so clearly the case with meningiomas, mostly in the multiple localization of these tumors, known as meningiomatosis. Here we would like to share our experience with a unique case of an atypical meningioma, which evolved in an anaplastic multiple meningiomatosis, invading the brain and associated wit…
Akute Gefäßerkrankungen in der Gastroenterologie. Der Gastroenterologe - Acute gastroenterologic vascular diseases
2012
Acute gastroenterologic vascular emergencies are common situations in emergency departments and the clinical consequences range from trivial to life-threatening. Only the early recognition of these symptom patterns and prompt use of the appropriate diagnostic tools lead to a correct diagnosis with subsequent potentially life-saving treatment. To decrease the high mortality rate of acute mesenteric ischemia (50%), aorto-enteric fistula (30–40%), visceral artery aneurysms (10– 100%) and Budd-Chiari syndrome new strategies with an endovascular approach are gaining importance and are partially replacing established diagnostic and therapeutic algorithms. This article provides a review of the dia…
