A rare cause of intestinal bleeding in a pediatric patient
No full textNeuromuscular and vascular hamartoma (NMVH) is an extremely rare entity of the small intestine, presenting radiologically with polyp-like lesions or stenoses and clinically with non-specific abdominal symptoms or gastrointestinal bleeding. Surgical resection is curative. We hereby report the case of an ileal NMVH in a pediatric patient, detected by capsule endoscopy and subsequently removed surgically, after localization of the lesion with intraoperative enteroscopy

No full textAcute gastroenteritis is a common cause of illness resulting in visits to the emergency department and outpatient clinics, hospitalizations and lost quality of life occurring in both domestic settings and among those traveling abroad. In addition, it is cause of outbreaks in closed communities such as schools, nursing homes and cruise ships. It is estimated that 1 in 6 people in the United States is subject to gastroenteritis each year with an estimated annual burden of 179 million outpatient visits, nearly 500,000 hospitalizations, and more than 5,000 deaths at an estimated cost upwards of US$150 million to the health-care economy. In Europe and Canada, the estimated annual incidence is between 0.1 to 3.5 episodes per person-year while in resource-limited countries the incidence of acute gastroenteritis is often not evaluated nor included in any specific review. It usually occurs at a baseline frequency, superimposed with epidemic cases of diarrhea, either dysentery or watery diarrhea.Acute gastroenteritis is considered a major public health issue against which control efforts are needed. Several societies and government-sponsored guidelines for the diagnosis and management of acute gastroenteritis in adults are updated periodically, globally the most used and updated are those provided by the World Gastroenterology Organization (WGO), the Infectious Diseases Society of America (IDSA) and the American College of Gastroenterology (ACG). Illness and death from clinical conditions caused by gastroenteritis, especially those related to contaminated food, are a constant threat to public health and a significant obstacle to socio-economic development worldwide. In 2010 a specific Reference Group (FERG) established by World Health Organization (WHO) found that the global burden of acute gastroenteritis is comparable to those of the major infectious diseases, HIV/AIDS, malaria and tuberculosis. The diagnosis of acute gastroenteritis is mainly clinical with evidence diarrhea of rapid onset that lasts less than two weeks and may be accompanied by nausea, vomiting, fever, or abdominal pain. Stool examination and culture to determine etiology should be performed on patients at high risk of severe illness and for whom identification of a pathogen would be important both for the patient and for public health. The treatment of the acute disease is based on: Fluid maintenance and repletion; adaptation of diet; use of probiotics and antibiotics depending on the etiology; use of non-specific anti-diarrheal drugs
THERAPEUTIC CHOICES IN ACUTE GASTROENTERITIS IN ADULTS
No full textAcute diarrhea is a very common illness among populations of all ages. Infective diarrhea accounts for most episodes of acute gastroenteritis in adults, and viruses are the most common etiologic agents. In developing countries, acute diarrhea is still cause of mortality, while in developed countries it impacts importantly the quality of life and may worsen underlying diseases such as nephropathies, cardiac diseases or diabetes. Therefore, the optimization of the treatment of acute gastroenteritis is essential all over the world. Acute diarrhea may be managed in hospitalization or with home medication, based on the severity of the disease and eventual comorbidities of the patient or complications. Therapy of acute diarrhea is based generally on the correction of fluid and electrolytes loss, on symptoms control and on the use of specific medications depending on etiology. Dehydration management should always be prompt and adapted to the severity of dehydration; oral rehydration is usually preferred, by using oral rehydration solutions; nonspecific antidiarrheal drugs are mainly used for symptoms controls and include antimotility drugs loperamide and dyphenoxylate, and antisecretory drugs bismuth subsalicylate and racecadotril; adsorbent agents as diosmectite may be applied as adjunctive treatments; antimicrobial therapy is indicated in case of acute infectious diarrhea, although it is not necessary for all etiologies; specific probiotic strains may be also applied in diarrhea’s treatment as they help in the reestablishment of a balanced intestinal microbiota
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
CARATTERIZZAZIONE STRUMENTALE DI SENSORI ATTIVI A TEMPO DI VOLO (TOF) E A TRIANGOLAZIONE. UTILIZZO DI LASER SCANNER SU SUPERFICI MARMOREE DI EPOCA ROMANA

UNA PIPELINE PER L’ACQUISIZIONE DI DATI 3D
No full textIl capitolo descrive la filiera di produzione di modelli 3D digitali dall’acquisizione alla visualizzazione dei modelli 3D spiegandone metodologie e approcci. In particolare sono trattati la definizione dei metodi e degli strumenti di rilievo al fine della costruzione dei modelli, cioè il rilievo con laser scanner, il rilievo mediante fotogrammetria digitale e l’integrazione di differenti tecniche. Successivamente sono affrontati i metodi di manipolazione dei modelli 3D, di segmentazione e classificazione semantica, di generazione dell’output per la visualizzazione
