Cervical lymph node metastasis in squamous cell carcinoma of the buccal mucosa: a retrospective study on pattern of involvement and clinical analysis
2020
Background The study was performed with an aim to map the pattern of metastasis of squamous cell carcinomas of buccal mucosa to various cervical lymph node levels and analyze its correlation with primary tumor size and histo-pathological grading. Material and Methods 254 patients with squamous cell carcinoma of the buccal mucosa treated with surgery first approach were analyzed retrospectively. The tumor size was noted from pre-operative CT Scans and were divided into early and advanced tumors. The resected specimen was studied to note the histo-pathological grading of the squamous cell carcinoma and the metastatic deposits at various lymph node levels. Results Out of 254 patients (149 fema…
Prognostic indicators for squamous cell carcinoma of the oral cavity: a clinicopathologic correlation.
1997
Fifty-three patients with T1 squamous cell cancer of the floor of mouth and ventral surface of the tongue with a known clinical outcome were retrospectively analyzed and arbitrarily divided into "aggressive" and "nonaggressive" groups based on their clinical behavior. Various host and tumor factors were then evaluated in an attempt to determine whether the tumor behavior could have been predicted. The paraffin-embedded tumor specimens were evaluated for tumor differentiation, tumor thickness and tumor invasion, microvessel density, and p53 expression. In addition, a composite morphologic grading score was obtained by combining cell differentiation, nuclear polymorphism, mitosis activity, de…
Prognosis in lower lip squamous cell carcinoma: assessment of tumor factors.
1998
We studied a consecutive series of 54 cases of lower lip squamous cell carcinoma (LLSCC) in order to identify any variables which might predict the development of lymph node metastases. The cases were divided into 38 tumors without metastases (group I) and 16 tumors with lymph node metastases (group II). The following factors were investigated: tumor size, histologic grading maximal thickness, perineural invasion, DNA ploidy and PCNA expression. In conclusion, we found that LLSCC greater than 2 cm in diameter, with histological grading G3-G4, thickness of more than 6 mm, DNA aneuploidy and high PCNA expression (PCNA LI > 0.48), were at high risk for the development of lymph node metastases.
Resection of the mesopancreas (RMP): a new surgical classification of a known anatomical space
2007
Abstract Background Prognosis after surgical therapy for pancreatic cancer is poor and has been attributed to early lymph node involvement as well as to a strong tendency of cancer cells to infiltrate into the retropancreatic tissue and to spread along the peripancreatic neural plexuses. The objective of our study was to classify the anatomical-surgical layer of the mesopancreas and to describe the surgical principles relevant for resection of the mesopancreas (RMP). Immunohistochemical investigation of the mesopancreatic-perineural lymphogenic structures was carried out with the purpose of identifying possible routes of metastatic spread. Methods Resection of the mesopancreas (RMP) was per…
Kawasaki disease: guidelines of the Italian Society of Pediatrics, part I - definition, epidemiology, etiopathogenesis, clinical expression and manag…
2018
Abstract The primary purpose of these practical guidelines related to Kawasaki disease (KD) is to contribute to prompt diagnosis and appropriate treatment on the basis of different specialists’ contributions in the field. A set of 40 recommendations is provided, divided in two parts: the first describes the definition of KD, its epidemiology, etiopathogenetic hints, presentation, clinical course and general management, including treatment of the acute phase, through specific 23 recommendations. Their application is aimed at improving the rate of treatment with intravenous immunoglobulin and the overall potential development of coronary artery abnormalities in KD. Guidelines, however, should…
A 7-Year-Old Boy and a 14-Year-Old Girl Initially Diagnosed with Toxic Shock Syndrome and Tested Positive for SARS-CoV-2 Infection, Supporting a Diag…

Case series Patients: Male, 7-year-old • Female, 14-year-old Final Diagnosis: Multisystem inflammatory syndrome in children (MIS-C) Symptoms: Muscular weakness • shock Medication: — Clinical Procedure: — Specialty: Critical Care Medicine • Infectious Diseases • Pediatrics and Neonatology • Rheumatology Objective: Unusual clinical course Background: Multisystem inflammatory syndrome in children (MIS-C) has recently been described in children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This report describes 2 children with MIS-C who were initially diagnosed with toxic shock syndrome but who tested positive for SARS-CoV-2 infection on reverse transcription-polym…

Protein Cargo of Salivary Small Extracellular Vesicles as Potential Functional Signature of Oral Squamous Cell Carcinoma
2021
The early diagnosis of oral squamous cell carcinoma (OSCC) is still an investigative challenge. Saliva has been proposed as an ideal diagnostic medium for biomarker detection by mean of liquid biopsy technique. The aim of this pilot study was to apply proteomic and bioinformatic strategies to determine the potential use of saliva small extracellular vesicles (S/SEVs) as a potential tumor biomarker source. Among the twenty-three enrolled patients, 5 were free from diseases (OSCC_FREE), 6 were with OSCC without lymph node metastasis (OSCC_NLNM), and 12 were with OSCC and lymph node metastasis (OSCC_LNM). The S/SEVs from patients of each group were pooled and properly characterized before perf…
TA-MUC1 epitope in non-small cell lung cancer
2007
MUC1 (CD227), an established tumor marker, is expressed on glandular epithelia and on epithelial tumors. Tumor MUC1 differs from normal MUC1 by modified glycan side chains. Recently, a novel carbohydrate-induced conformational tumor-associated MUC1 epitope (TA-MUC1) was described, whose clinical relevance in lung cancer is not known. Eighty-five paraffin embedded tissue sections of non-small cell lung cancer (NSCLC) patients (73% male; mean age 64+/-9 years) were stained with the monoclonal antibody PankoMab (against TA-MUC1) and compared with the established antibodies E29 and 214D4 regarding prognostic relevance. TA-MUC1 is virtually absent in bronchial epithelium. As shown by multivariat…
Coronary artery bypass grafting in adult coronary artery disease due to suspected Kawasaki disease in childhood
2000
Development of coronary artery aneurysms is one typical complication of Kawasaki disease and can cause coronary artery disease even in early childhood. Information about course and outcome in adults is rare. Here, we present a 49-year-old man with serious three-vessel coronary artery disease and giant coronary artery aneurysms following suspected Kawasaki disease.
