Surveillance of Municipal drinking-water supply after a Norovirus outbreak in Italy
BACKGROUND Norovirus (NoV), in the family Caliciviridae, is the major causative agent of non-bacterial acute gastroenteritis, whose possible routes of transmission include drinking water. During March 2011 an outbreak of gastroenteritis was identified by the local public health service in S. Stefano di Quisquina, Sicily, Italy. Over two weeks, 156 cases were identified and NoV genotype GII.4 v2010 was detected in stool samples from eleven out of twelve patients. The finding of identical genomic sequences between patients suggested a common infection source and an epidemiological investigation indicated a possible correlation to municipal drinking water consumption. One of the wells supplyin…
Bilateral double renal arteries and bilateral renal veins. A color-Doppler sonographic finding in a patient with arterial hypertension
Ultrasound-guided port-a-cath positioning with the new one-shoot technique: thoracic complications.
Port-a-cath catheterization is often required for those patients who need long-term therapies (malnutrition, neoplasm, renal failure, other severe diseases). The use of ports for a wide range of indications is not exempt from complications. Ultrasound-guided central venous catheterization (CVC) is a safe and fast technique for the introduction of the catheter inside a central vein. This retrospective study reports our experience with US-guided CVC in patient eligible for port-a-cath implantation.From January 2007 to March 2017, 108 CVC (out of 770 procedures), were positioned using an ultrasound guide, with the new "one-shoot technique" (group 1) and the classic Seldinger technique (group 2…
Effects of voids and flaws on the mechanical properties and on intergranular damage and fracture for polycrystalline materials
It is widely recognized that the macroscopic material properties depend on the features of the microstructure. The understanding of the links between microscopic and macroscopic material properties, main topic of Micromechanics, is of relevant technological interest, as it may enable the deep understanding of the mechanisms governing materials degradation and failure. Polycrystalline materials are used in many engineering applications. Their microstructure is determined by distribution, size, morphology, anisotropy and orientation of the crystals. It worth noting that also the physical-chemical properties of the intergranular interfaces, as well as the presence of micro-imperfections within…
Scar endometriosis: not a rare cause for a painful scar
Introduction. Endometriosis has been described as the presence of endometrial tissue outside uterine cavity. Scar endometriosis (SE) is a rare disease reported in 0.03-1.08% of women following gynaecologic surgery. In our retrospective observational cohort study we studied anamnesis, symptoms, surgical procedures and outcomes linked to scar endometriosis in our medical experience from 2004 to 2018. Methods. We reviewed the medical records of 46 patients with a histopathological diagnosis of SE. All patients had a history of at least one previous caesarean section (n=46, 100%). Forty-two patients (91,3%) complained gradually growing nodular abdominal mass near or adjacent to caesarean incisi…
Relazioni tra stiffness aortica ed indice di resistenza intrarenale nell’ipertensione arteriosa
Per molti anni lo studio mediante eco-color-doppler dei parametri semiquantitativi emodinamici renali è stato utilizzato per rilevare le alterazioni della perfusione del rene trapiantato, per la diagnosi della stenosi dell’arteria renale o per valutare la progressione di alcune nefropatie. Più recentemente è stato osservato che tali parametri, ed in particolare l’indice di resistenza intrarenale (IR), non sono soltanto espressione della perfusione parenchimale, ma sono associati anche ad alterazioni morfo-funzionali sistemiche dell’albero vascolare. Vari studi hanno dimostrato come la stiffness aortica vada aumentando con il progressivo deterioramento della funzione renale. Tuttavia, dati c…
Lumevis ™: a new medical device to prepare patients for esophagogastroduodenoscopy. Experimental clinical study.
Esophagogastroduodenoscopy (EGDS) is the gold standard exam for upper gastrointestinal diseases. EGDS is very important in Early Gastric Cancer diagnosis and treatment but it is an operator-dependent exam and there are lots of factors that reduce its visibility (mucus, bubbles and foam).The aim of our study is to evaluate if the use of Lumevis™ improves mucosa visualization during EGDS without increasing the examination time and complications' rate and comparing the differences in patients prepared with water or no intervention.we recruited 50 patients from 01/08/2020 to 31/08/2020 who came to our observation for epigastric pain, dyspepsia and gastroesophageal reflux (GERD). For each patien…
