Plunging Ranula in a 78- year- old Male ? a rare case report
2018
The term Ranula is a Latin word meaning frog. It refers to a bluish translucent cystic lesion in the floor of the mouth resembling the underbelly of a frog. Ranulas can be true cysts occurring due to ductal obstruction of the sublingual gland or a minor salivary gland or a pseudocyst as a result of ductal injury leading to extravasation and accumulation of saliva in the surrounding tissues. Clinically ranulas present as intraoral or plunging ranulas. The prevalence of ranula is 0.2% per 1000 patients Ranulas account for 6% of all salivary gland cysts. Ranulas are more common in children and young adults. However the plunging type occurs most commonly in the later third decade. The diagnosis…
A Rare Case of Primary Gastric Melanoma
2019
Abstract Primary melanomas in the gastrointestinal tract are extremely rare, with an estimated prevalence of 0.5 to 1 case per million. Primary mucosal melanomas of gastric origin account for approximately 1–3% of all primary melanomas in the gastrointestinal tract. We present the case of a patient who underwent surgery due to primary gastric melanoma.
Effects of oxidative modifications induced by the glycation of bovine serum albumin on its structure and on cultured adipose cells
2005
Non-enzymatic glycosylation (glycation) and oxidative damages represent major research areas insofar as such modifications of proteins are frequently observed in numerous states of disease. Albumin undergoes structural and functional alterations, caused by increased glycosylation during non insulin-dependent diabetes mellitus, which is closely linked with the early occurrence of vascular complications. In this work, we first characterized structural modifications induced by the glycation of bovine serum albumin (BSA). A pathophysiological effect of glycated BSA was identified in primary cultures of human adipocytes as it induces an accumulation of oxidatively modified proteins in these cell…
De Garengeot Hernia: Case Report and Review of the Literature of a Rare Femoral Hernia
2021
AbstractDe Garengeot hernia is a rare femoral hernia defined as the presence of the appendix within the femoral hernia sac. The incidence of appendicitis in this type of hernia is a rare condition that accounts for 0.08–0.13% of all De Garengeot hernias. We describe the case of a 61-year-old woman that presented at the emergency department with a tender mass (diameter 10 × 8 cm) in the right groin region for 5 days associated with pain in lower right abdomen and accompanied by fever (38 °C). Computed tomography (CT) of the abdomen revealed the presence of a complex fluid collection with small foci of air in the right inguinal region, measuring 9 × 7 × 10 cm in the 3 orthogonal dimensions an…
Treatment challenges in and outside a network setting: Soft tissue sarcomas
2019
Patients with soft tissue sarcoma (STS) experienced better outcomes when treated according to existing clinical practice guidelines either at reference institution or dedicated treatment networks. Despite increasing evidence supporting referral to sarcoma specialised units, up to half of patients are not managed according to guidelines, particularly those in the early stage of their disease requiring surgery. Also, criteria to certify expertise of institutions, such as the treatment volume, are debated and health authorities have only recently started identification of these centres and creation of treatment networks in Europe as well as in several countries. This process have important imp…
Muscle Oxygen Delivery in the Forearm and in the Vastus Lateralis Muscles in Response to Resistance Exercise: A Comparison Between Nepalese Porters a…
2020
Altitude ascending represents an intriguing experimental model reproducing physiological and pathophysiological conditions sharing hypoxemia as the denominator. The aim of the present study was to investigate fractional oxygen extraction and blood dynamics in response to hypobaric hypoxia and to acute resistance exercises, taking into account several factors including different ethnic origin and muscle groups. As part of the “Kanchenjunga Exploration & Physiology” project, six Italian trekkers and six Nepalese porters took part in a high altitude trek in the Himalayas. The measurements were carried out at low (1,450 m) and high altitude (HA; 4,780 m). Near-infrared spectroscopy (NIRS)-d…

Towards the Point of Care and Noninvasive Classification of Bladder Cancer from Urine Sediment Infrared Spectroscopy. Spectral differentiation of nor…
2021
Abstract Bladder cancer (BC) is the 9th cancer cause of death and one of most cost-intensive in the world. The diagnostic tools are still not at all satisfactory. Herein we evaluated the potential of infrared spectroscopy to detect molecular changes that precede and accompany the carcinogenesis in voided urine sediment. We collected 165 samples from patients being diagnosed for BC and measured them with attenuated total reflectance Fourier transformed infrared spectroscopy (ATR FTIR). Samples were primarily divided into three groups according to cytology that indicated the presence of normal, abnormal and cancer cells. ATR FTIR spectra of sediments were analyzed with the use of partial leas…
Infrared Thermography Versus Conventional Image Techniques in Pediatrics: Cases Study
2017
The use of infrared thermography has been shown to be useful in several areas. Its applicability in medicine is based on the fact that the skin emits spontaneously and continuously infrared radiation, whose body distribution is symmetrical in a healthy individual. Infrared thermography can offer an alternative to X-rays for a large number of diseases related to peripheral vascularization. In these cases, infrared thermography can avoid the use of biologically ionizing radiation. This is of special interest in pediatric patients who, because of their age, are more radiosensitive.
Inspection of architectural structures with integrated electrical methodologies and infrared thermography
2005
B030 INSPECTION OF ARCHITECTURAL STRUCTURES WITH INTEGRATED ELECTRICAL METHODOLOGIES AND INFRARED THERMOGRAPHY Abstract 1 The attention of this paper was focused on the detection of moisture and local inhomogeneities inside architectural structures with electrical methodologies and infrared thermography. To this end a suitable specimen was fabricated using a mixture of sand water and concrete and with slag inclusions. To monitor the moisture variation with time in concrete nondestructive evaluation with both the techniques was made three months after the specimen fabrication and repeated again six months later. Introduction The inspection of architectural structures generally includes vario…
