CT enterography as a powerful tool for the evaluation of inflammatory activity in Crohn’s disease: relationship of CT findings with CDAI and acute-ph…
2014
Few studies have correlated computed tomography enterography (CTE) findings with Crohn’s disease (CD) clinical and biochemical activity. The aim of this study was to evaluate correlations between CTE findings with CD activity. The CTE datasets from 62 patients were retrospectively reviewed for different parameters: bowel wall thickening and hyperenhancement, mesenteric alterations, abdominal free fluid and complications related to the disease (fistulas, strictures, abscesses). Activity was assessed using the Crohn’s Disease Activity Index (CDAI) and some biochemical markers (C-reactive protein, erythrocyte sedimentation rate, alpha 2-globulins, fibrinogen, platelets, haemoglobin). Correlati…
Summary of hands-on supermicrosurgery course and live surgeries at 8th world symposium for lymphedema surgery.
2019
The hands-on supermicrosurgery course provided participants a valuable learning experience of in-depth practices of supermicrosurgical skills with experts. Seven live surgeries were successfully demonstrated at 8th World Symposium for Lymphedema Surgery. Variable donor sites for vascularized lymph node transfer were the submental, supraclavicular, groin, and omental; while the recipient sites included the wrist and axilla in upper limb; and popliteal and groin in the lower limb. The therapeutic and preventive lymphovenous anastomosis was also satisfactorily performed.
Abdominal Ultrasound Does Not Reveal Significant Alterations in Patients With Nonceliac Wheat Sensitivity
2017
Abstract GOALS: The goal of this study was (A) to evaluate abdominal ultrasound signs in nonceliac wheat sensitivity (NCWS) patients for features useful in diagnosis and (B) to compare these aspects with those of celiac patients to assess whether ultrasound can be useful in the differential diagnosis between NCWS and celiac disease (CD). BACKGROUND: NCWS diagnosis is difficult as no biomarkers of this condition have as yet been identified. In CD ultrasound aspects have been identified that have a good diagnostic accuracy. STUDY: We prospectively recruited 45 NCWS patients (11 males, 34 females; mean age 35.7 y). Three control groups were included: (A) 99 age-matched CD patients; (B) 18 pati…
Selective approach to the treatment of oesophageal cancer
1996
Abstract Between September 1985 and December 1994, 322 patients with oesophageal cancer were treated. Of the 190 patients who underwent operation, 173 had an oesophageal resection; in 124 this was performed as an abdominothoracic resection and in 49 by the transhiatal approach. The assessment of radicality after histological examination revealed a curative (R0) resection in 121 patients (70 per cent) and a palliative (R1-R2) resection in 52 (30 per cent). Prognosis was correlated with the extent of mediastinal lymph node dissection. In 77 patients with stage pT1–3 pN0–1 pM0 the 5-year survival rate was 40 per cent after abdominothoracic resection with two-field lymph node dissection and zer…
Ultrasound detection of abdominal lymphadenomegaly in subjects with hepatitis C virus infection and persistently normal transaminases: a predictive i…
1998
The indications for liver biopsy in anti-HCV-positive patients with persistently normal alanine aminotransferase levels are not clearly established. Recent studies have correlated the presence of abdominal lymphoadenomegaly with disease severity in patients with chronic hepatitis C. Our study aimed to evaluate the frequency of abdominal lymphoadenomegaly in an anti-HCV positive blood donor population with persistently normal alanine aminotransferase and the relationship of abdominal lymphoadenomegaly with the severity of liver changes.Eighty-six anti-HCV positive blood donors (58 M, 28 F) with normal alanine aminotransferase were followed up for a median of 31 months (range 12-50). To evalu…
Evaluation of the Upper Limb Lymphatic System: A Prospective Lymphoscintigraphic Study in Melanoma Patients and Healthy Controls
2016
Background Current research on the upper limb lymphatic system mainly studies breast cancer patients with unilateral lymphedema. Without preoperative lymphoscintigraphy, the contralateral limb is used as a control, assuming that it is functionally intact. Few lymphoscintigraphic studies investigate patients before any axillary surgery. The purpose of this study was to evaluate, through lymphoscintigraphy, the preoperative condition of the upper limb lymphatic system in melanoma patients and healthy controls. Methods Two groups were studied: the study group (16 patients with trunk/upper limb melanoma candidates for axillary sentinel lymph node biopsy) and the control group (10 healthy volunt…
The prognostic value of sentinel lymph node micrometastases in patients with invasive breast carcinoma
2016
The prognostic value of sentinel lymph node micrometastases in invasive breast cancer patients is still widely debated. Even if, in the absence of unequivocal guidelines, the axillary lynphadenectomy is not still performed in the routine clinical care of these patients.We have retrospectively analyzed 746 patients with operable invasive breast cancer and clinically negative axillary lymph nodes. These patients underwent conservative surgery or total mastectomy with sentinel lymph node biopsy. Patients with micrometastases in the sentinel lymph node treated with axillary dissection has been checked and the involvement of the remaining lymph nodes analyzed. Patients with micrometastases in th…
Application of a predictive model of axillary lymph node status in patients with sentinel node metastasis from breast cancer. A retrospective cohort …
2016
Abstract Background and objectives The Axillary Lymph Node Dissection (ALND) is the standard treatment in patients with invasive breast cancer and sentinel node metastasis, but in 60% of the cases there is no further axillary neoplastic involvement, so this invasive intervention represents an overtreatment. The purpose of the study is to identify patients with low risk of additional nodal metastases, to omit ALND. Methods The MSKCC Additional nodal metastasis nomogram was applied on a sample of 175 patients with invasive breast cancer who underwent ALND after detection of macrometastasis with the extemporaneous examination of the sentinel lymph node. Patients were classified as "low risk" w…
Is extracapsular nodal extension in sentinel nodes a predictor for nonsentinel metastasis and is there an impact on survival parameters?-A retrospect…
2016
The Z0011 trial has fundamentally changed axillary management in breast cancer patients. However, some important questions remain, like the role of extracapsular nodal extension (ENE) in positive sentinel nodes and the need for further axillary treatment. In this retrospective cohort study, we reviewed and analyzed data from 342 clinically node negative (cN0) breast cancer patients with a positive sentinel node and subsequent axillary lymph node dissection (ALND) from the BRENDA data base. The 104 (30.4%) ENE positive patients had a significantly higher proportion of ≥3 positive axillary lymph nodes (65.0%) compared to ENE negative patients with a positive sentinel node (21.4%). Likewise, E…
Solid variant of mammary "adenoid cystic carcinoma with basaloid features" merging with "small cell carcinoma"
2005
We describe a rare case of a solid variant of a mammary adenoid cystic carcinoma with basaloid features (sbACC) and its coexistence with a "small cell" carcinoma (SCC), identified and confirmed by histological and immunohistochemical observations: the absence of glandular structures and PAS-positive globules, positivity for neuroendocrine markers (NSE, synaptophysin and chromogranin), and negativity for 34betaE12 and SMA actin were the aspects suggesting the presence of SCC. Furthermore, positivity for CD10 was found both in sbA CC and in SCC, supporting the hypothesis that the two components share the same histogenetic myoepithelial origin and represent an example of dedifferentiation alon…
