Kryotherapie primärer und sekundärer Lebertumoren
2002
AIMS We assessed the morbidity, mortality and efficacy of cryotherapy for primary and secondary malignant liver tumours in a prospective case control study. METHODS Since 1996 we performed 77 cryosurgical procedures on 71 patients. 6 patients had hepatocellular carcinoma, the remainders metastases, mainly of colorectal origin (n = 49). Cryotherapy was used when a complete tumour resection was not feasible, but complete tumour destruction by cryotherapy seemed possible. Mean follow-up was 21 months. RESULTS The mean number of lesions per patient was 2.6 (1-10) with a mean maximum diameter of 3.7 cm (1-11). In 36 of 71 patients cryotherapy was used in combination with liver resection. Morbidi…
Solitary Myofibroma of the Bladder Trigone in a 3-Month-Old Patient: First Case Report
2016
Visceral solitary myofibromas are uncommon in childhood. We report a case of a solitary asymptomatic visceral myofibroma of the bladder trigone occurring in a 3-month-old boy. Once malignancies were ruled out by cystoscopy, radical excision was performed in order to avoid any potential impairment of bladder dynamic. Postoperative course was uneventful and patient was discharged on day 3 after surgery. After 36 months of follow-up, the patient is toilet-trained and remains well; bladder function is normal.
Odontogenic fibroma — a case report
2014
Abstract IThe present study outlines the case of a 30-year-old patient with central odontogenic fibroma. The tumour developed in the alveolar process of the maxilla in the area of 13–15. The study describes the clinical symptoms, the radiological image, treatment method and histopathological image of the tumour. The study also presents a one-year period of post-surgical observation.
Buccal fat pad excision for cheek refinement: A systematic review
2021
Background Buccal Fat Pad (BFP) excision has become an aesthetic surgical procedure. Although this procedure is quite common, it is important to bear in mind that the scientific evidence supporting the efficacy of this treatment is scarce and of low quality. The purpose of this systematic review was to analyse all relevant data to assess the efficacy and safety of BFP excision for improving midface aesthetics. Material and Methods A thorough search of MEDLINE (PubMed), Scopus and Cochrane Library databases was conducted. The PICO approach was used where healthy patients seeking cheek slimming and facial silhouette refining undergo BFP excision and were compared before and after surgery in t…
The Transcallosal Anterior Interfoniceal Approach: A Microsurgical Anatomy Study
2014
Objectives: A plethora of surgical strategies have been described to reach deeply lesions situated within the third ventricle, including the Rosenfeld or anterior transcallosal interfoniceal approach (TAIF). Firstly, introduced in 2001, it consists of a small callosotomy followed by the midline transseptal dissection of fornices to enter the roof of the third ventricle. The aim of this microsurgical anatomy study is to describe and show each stage of the surgical procedure, focusing on the possible trajectories to anatomic landmarks. Participants: A total of twenty adult cadaveric specimens were used in this study. Using x3 to x40 magnifications the surgical dissection was carried out in a …
COX-2 expression in chondrosarcoma: A role for celecoxib treatment?
2010
Chondrosarcomas are resistant to conventional chemo- and radiotherapy. A subset of chondrosarcomas arises secondarily in the benign tumour syndromes enchondromatosis (EC) and multiple osteochondromas (MO), and prevention of tumour development would greatly improve prognosis. We therefore investigated the effect of selective COX-2 inhibition on chondrosarcoma growth. COX-2 expression was studied in central- and peripheral cartilaginous tumours. The effect of COX-2 inhibition was assessed in four high-grade chondrosarcoma cell lines using celecoxib and NS-398 treatment. COX-2 activity (prostaglandin E-2 (PGE(2)) ELISA) and cell viability were measured. The (prophylactic) effect of celecoxib o…
Tumours of Nasal Septum: A Retrospective Study of 32 Patients
2022
Objective: Tumours of the nasal septum are a rare and heterogeneous group of lesions in the sinonasal tract. The management of the different lesions of this site is debated. The aim of this study is to share our experience on a rare clinical condition and stimulate other centres to publish theirs. Methods: We retrospectively analysed the databases of sinonasal tumours treated at the Sections of Otolaryngology (ENT) of two University Hospitals (Palermo and Genova) between 2012 and 2020. Results: From the two databases, a cohort of 32 patients with tumours of nasal septum were selected. All patients underwent an endoscopic examination. Large tumours underwent preoperative computed tomography …
Clinical Significance of Tie-2-Expressing Monocytes/Macrophages and Angiopoietins in the Progression of Ovarian Cancer—State-of-the-Art
2022
Tumour growth and metastasis are specific to advanced stages of epithelial ovarian cancer (EOC). Tumour angiogenesis is an essential part of these processes. It is responsible for providing tumours with nutrients, metabolites, and cytokines and facilitates tumour and immune cell relocation. Destabilised vasculature, a distinctive feature of tumours, is also responsible for compromising drug delivery into the bulk. Angiogenesis is a complex process that largely depends on how the tumour microenvironment (TME) is composed and how a specific organ is formed. There are contrary reports on whether Tie-2-expressing monocytes/macrophages (TEMs) reported as the proangiogenic population of monocytes…
CD3+ and CD8+ T-Cell-Based Immune Cell Score and PD-(L)1 Expression in Pulmonary Metastases of Microsatellite Stable Colorectal Cancer
2022
Simple Summary The lung is the second most common site of metastases in colorectal cancer (CRC). The aim of our study was to evaluate the prognostic value of CD3+ and CD8+ T-cell density based immune cell score (ICS) and PD-1/PD-L1 expression in resected pulmonary metastases of microsatellite stable CRC. The T-cell infiltration was higher in the first pulmonary metastases compared to primary tumour. Pulmonary metastases with high ICS had improved survival compared to low ICS after adjusting for confounders. High tumour cell PD-L1 expression was associated with favourable prognosis. Our results might have clinical feasibility in planning future therapies. Abstract The objective of this study…
Rho GTPases in human breast tumours: expression and mutation analyses and correlation with clinical parameters
2002
In the present study, we addressed the question of a putative relevance of Rho proteins in tumour progression by analysing their expression on protein and mRNA level in breast tumours. We show that the level of RhoA, RhoB, Rac1 and Cdc42 protein is largely enhanced in all tumour samples analysed (n=15) as compared to normal tissues originating from the same individual. The same is true for 32P-ADP-ribosylation of Rho proteins which is catalysed by Clostridium botulinum exoenzyme C3. Also the amount of Rho-GDI and ERK2 as well as the level of overall 32P-GTP binding acvitity was tumour-specific elevated, yet to a lower extent than Rho proteins. Although the amount of Rho proteins was enhance…
