Serum coding and non-coding RNAs as biomarkers of NAFLD and fibrosis severity
2019
Background: In patients with NAFLD liver biopsy is the gold standard to detect NASH and stage liver fibrosis. We aimed to identify differentially expressed mRNAs and non-coding RNAs in serum samples of biopsy-diagnosed mild and severe NAFLD patients with respect to controls and to each other. Methods: We first performed a whole transcriptome analysis through microarray (n=12: 4 CTRL; 4 mild NAFLD: NAS≤4 F0; 4 severe NAFLD NAS≥5 F3), followed by validation of selected transcripts through qPCRs in 88 subjects: 63 NAFLD, 25 CTRL. A similar analysis was also performed on HepG2 exposed to Oleate:Palmitate or only Palmitate (cellular model of NAFL/NASH) at intracellular/extracellular levels. Tran…
Gastric and Rectal Metastases from Malignant Melanoma Presenting with Hypochromic Anemia and Treated with Immunotherapy
2017
The authors present a case of an 80-year-old Caucasian male with multiple gastric and rectal metastases from malignant melanoma presenting with hypochromic anemia as the sole symptom of disease without evidence of cutaneous and ocular tumor localization. The patient had a medical history positive for malignant lentigo melanoma of the occipital region of the scalp and early stage laryngeal squamous cell carcinoma and prostatic carcinoma treated with radiation therapy. The authors make some considerations on intestinal involvement by metastatic melanoma and discuss the choice of not treating with endoscopic procedures the gastric metastatic lesions most likely responsible for the clinical sig…
Perioperative Chemotherapy in Poorly Differentiated Neuroendocrine Neoplasia of the Bladder: A Multicenter Analysis
2020
There is scant evidence about optimal management of poorly differentiated neuroendocrine carcinoma of the bladder (BNEC). We performed a multicenter retrospective study on BNEC patients from 13 Italian neuroendocrine-dedicated centers to analyze strategies associated with better outcomes. Mixed adeno-neuroendocrine carcinomas (MANEC) were included. We analyzed overall survival (OS) in the overall cohort, relapse-free survival (RFS) in radically operated patients and progression-free survival (PFS) in patients who received chemotherapy for metastatic disease. Fifty-one BNEC patients were included (male: 46, median age: 70 years). Overall, median OS was 16.0 months, radical tumor resection wa…
Neoadjuvant chemotherapy for stage IIIA-N2 non-small cell lung cancer
2005
Neoadjuvant chemotherapy in potentially resectable stage IIIA-N2 non-small cell lung cancer (NSCLC) has become standard of treatment in the last years. Two randomised pioneer phase III trials conducted with second generation platinum combinations had demonstrated an advantage in survival of induction chemotherapy followed by surgery versus surgery alone. Subsequently, a wide number of phase II studies with third generation platinum-based doublets or triplets have increased the evidence of the activity as well as the good tolerability of this approach. Nowadays, the main topics of ongoing clinical research are to assess the role of induction chemotherapy in early stage disease, and the role …
Mandibular Brown Tumor as a Result of Secondary Hyperparathyroidism: A Case Report with 5 Years Follow-Up and Review of the Literature
2021
Background: Brown tumor is a rare skeletal manifestation of secondary hyperparathyroidism. Although diagnosis of the disease is increasingly seen in early stages due to improved screening techniques, some patients still present in a progressed disease stage. The treatment depends on tumor mass and varies from a conservative approach with supportive parathyroidectomy to extensive surgical resection with subsequent reconstruction. Case presentation: We report a case of extensive mandibular brown tumor in a patient with a history of systemic lupus erythematosus, chronic kidney disease, and secondary hyperparathyroidism. Following radical resection of the affected bone, reconstruction could be …
Lack of association between proliferative verrucous leukoplakia and human papillomavirus infection.
2005
Purpose To analyze proliferative verrucous leukoplakia (PVL) for the presence of human papillomavirus (HPV) in different stages of the disease. Materials and Methods We studied 13 patients with PVL. In 10 patients (76.9%), a lesional biopsy was taken and frozen at −40°C. Four patients were instructed to mouth rinse with sterile sera. The biopsy and rinse samples were analyzed for HPV by PCR. Results We did not detect HPV infection in the PVL tissue or in the oral rinse of any of the 13 patients in any stage of the disease analyzed, neither in oral squamous cell carcinoma nor in the simple hyperkeratosis. Conclusion There was no association between PVL and HPV infection in our patients.
Automated DNA-image cytometry: a prognostic tool in infiltrating bladder carcinoma?
1987
In a retrospective study, paraffin-embedded cystectomy specimens obtained from 46 patients with bladder cancer (stage pT1 — pT4a, pN0, pN2) were analysed for tumor DNA ploidy and proliferation using automated image cytometry (LEYTAS). In 41 cases, DNA ploidy could be measured. Estimation of proliferation was possible in 26 tumors. The number of cells with a DNA content higher than 5C could be calculated in 38 of the tumors. All these three parameters are shown to correlate with patient outcome.
Clinicopathologic and DNA Flow Cytometric Analysis of Eighty-three Renal Cell Carcinomas
1995
The clinical and anatomopathologic features as well as DNA content of 83 renal cell carcinomas were analyzed. The possible interrelationship and prognostic value of these factors were also considered. The DNA study has been performed by flow cytometry using paraffin-embedded tissues. In each case an internal control with nonneoplastic renal tissue obtained in the same nefrectomy was also done in order to calculate the DNA index. Differences in patient age, nuclear grade, and mitotic activity were related with outcome; however, this relationship was not confirmed by the Cox test. Stage (P = .005), cell type (P = .002), and metastatic disease (P = .001) had independent prognostic values. Ren…
Different methods of cell quantification can lead to different results: a comparison of digital methods using a pilot study of dendritic cells in HIV…
2019
Background Although new digital pathology tools have improved the positive cell quantification, there is a heterogeneity of the quantification methods in the literature. The aim of this study was to evaluate and propose a novel dendritic cells quantification method in squamous cell carcinoma comparing it with a conventional quantification method. Material and Methods Twenty-six squamous cell carcinomas HIV-positive cases affecting the oropharynx, lips and oral cavity were selected. Immunohistochemistry for CD1a, CD83, and CD207 was performed. The immunohistochemical stains were evaluated by automated examination using a positive pixel count algorithm. A conventional quantification method (u…
Reliability of liver stiffness measurement in non-alcoholic fatty liver disease: the effects of body mass index
2011
Summary Background Liver stiffness measurement (LSM) using transient elastography (TE) is used to stage fibrosis in patients with liver disease, diagnostic reliability and the factors affecting its performance in patients with non-alcoholic fatty liver disease (NAFLD) are incompletely understood. Aim To assess LSM. Methods Consecutive NAFLD patients (n = 169), assessed by liver biopsy (Kleiner score), anthropometrical, biochemical and metabolic features, underwent LSM using TE with standard M probe. Results Liver stiffness measurement was not reliable in 23 patients (14%) due to obesity. Among patients with a reliable TE, a LSM value >7.25 kPa was the best cut-off for predicting signifi…
