A method for skin malformation classification by combining multispectral and skin autofluorescence imaging
2018
As the incidence of skin cancer is still increasing worldwide, there is a high demand for early, non-invasive and inexpensive skin lesion diagnostics. In this article we describe and combine two skin imaging methods: skin autofluorescence (AF) and multispectral criterion p’. To develop this method, we used custom made prototype with 405 nm, 526 nm, 663 nm and 964 nm LED illuminations, perpendicular positioned linear polarizers, 515 nm filter and IDS camera. Our aim is to develop a skin lesion diagnostic device for primary care physicians who do not have experience in dermatology or skin oncology. In this study we included such common benign lesion groups as seborrheic keratosis, hyperkerato…
Benign Prostatic Hyperplasia: Correlations between Receptor Density and Binding Affinity of 1-Adrenoceptors and Several Clinical Parameters
2002
The aim of the study was to determine whether relations do exist between the concentration and activity of 1-adrenoceptors, both inside the prostatic adenoma and the periurethral zone corresponding to the bladder neck, and clinical and biological parameters such as symptoms, evaluated by the American Urological Association (AUA) score, age, weight of the prostate, PSA, and the flow rate. Twenty patients with symptomatic benign prostatic hyperplasia were selected for an open prostatectomy. One gram of tissue was dissected from inside the adenoma and 1 g from the periurethral zone corresponding to the bladder neck. The 1-adrenoceptors were evaluated for the apparent dissociation constant (Kd)…
Expression of gelatinases (MMP-2, MMP-9) and cyclooxygenases (COX-1, COX-2) in some benign salivary gland tumors.
2012
Salivary gland tumors, most of which are rare benign tumors, represent a histologically heterogenous group with the greatest diversity of morphological and cellular features. The aim of this study is to analyse the expression and possible interactions between gelatinases (MMP-2, MMP-9) and cyclooxygenases (COX-1, COX-2) in some benign salivary gland tumors. We investigated the expression of gelatinases and cyclooxigenases in control salivary gland, Pleomorphic adenoma and Warthin's tumor through immunohistochemistry and Reverse Transcription – Polymerase Chain Reaction (PCR). We identified the expression of both classes of enzyme in normal samples and in the two types of pathological sampl…

Diagnostic techniques and multidisciplinary approach in idiopathic granulomatous mastitis: A revision of the literature
2019
Idiopathic granulomatous mastitis (IGM) is a chronic benign inflammatory disease of the breast that may mimic breast cancer. It is most common in parous young fertile women, although it can occur in nulliparous women and in men. IGM is an idiopathic disease due to the influence of some environmental factors in genetically predisposed subjects. Several pathogenic hypothesis have been proposed in the last years (autoimmune, hormonal, infective genesis). IGM presents as a painful palpable mass located in one of the two udders. The skin is usually normal but could present signs of inflammation with or without lymph nodes involvement. Ultrasonography, mammography, magnetic resonance can be diagn…

UNA CHIRURGIA CONSERVATIVA DEI TUMORI BENIGNI DEL TESTICOLO IN ETA' PEDIATRICA? Analisi dei Risultati di una Casistica Multicentrica Retrospettiva (1…
1993
La Terapia Chirurgica dei tumori benigni del testicolo si basa sulla orchiectomia radicale inguinale. Tale criterio è stato messo in discussioneda alcuni Autori e per tale motivo sono stati valutati i risultati di una casistica nazionale multicentrica retrospettiva di 10 anni allo scopo di valutare la possibilità di una exeresi radicale conservativa di queste neoplasie
DOES STILL EXIST A CORRELATION BETWEEN X-RAYS OCCUPATIONAL EXPOSURE AND BENIGN NODULAR THYROID DISEASE?
2019
Objective: The prevalence of benign nodular thyroid disease in the general population is high, as shown by various studies, and the diagnosis is eased by the improved diagnostic capacity of the instruments used. The aim of the present study is the evaluation of occupational exposure to ionizing radiation as a possible significant risk factor in the determinism of this pathology. Method: A cross-sectional observational study in “A category” X-ray exposed workers (doctors, nurses, technicians) of the University Hospital of Palermo, compared with a sample of the general population, was carried out from June 2016 to June 2017. We evaluated data obtained from the Personal Health Records, includi…
Case report of necrotizing sialometaplasia
2010
Introduction: Necrotizing sialometaplasia is a rare inflammatory necrotizing reactive process that can involve minor and major salivary glands. Gland tissue ischaemia has been proposed as the aetiology. Case Report: A 21-year-old woman was referred with a 1-week history of bilateral painful swelling of the palate, with the development of two deep ulcers after the first 3 days. Ulcer edges were elevated but not indurated, and the bases had a necrotic appearance. An incisional biopsy of the margin of one ulcer confirmed the diagnosis of necrotizing sialometaplasia. The ulcers spontaneously healed within 8 weeks without treatment. Discussion: The clinical and histological similarity between th…
Quality of life improving after propranolol treatment in patients with Infantile Hemangiomas
2022
AbstractInfantile hemangiomas may affect the quality of life (QoL) of patients and their family members, as anxiety and worry may commonly occur in parents, also linked to the social adversion they experience. We underline the beneficial impact of oral propranolol therapy on QoL of patients with infantile hemangiomas (IH) and of their relatives. A specific questionnaire measuring QoL was administered to parents of IH patients at beginning and end of a treatment with oral propranolol. Different aspects were investigated: site of the lesion, age of patients at starting therapy, length of treatment, occurrence of adverse effects and persistence/recurrence of the vascular anomaly. In all cases …
