Internal Hernia Masquerading As Necrotizing Enterocolitis
2017
In extremely preterm infants, acute abdominal emergencies are fortunately less common with improving care. Spontaneous intestinal perforation and necrotizing enterocolitis are conditions where emergency surgery is most often needed. Conservative medical management and placement of temporary drain are often used in the initial management. Internal hernia (IH) is an uncommon cause of bowel obstruction in neonates, is difficult to diagnose and unfortunately are found only at autopsy. The presentation in preterm infants, distinction between these conditions, and the need for early diagnosis of IH are discussed.
Early intestinal perforation secondary to congenital mesenteric defects
2016
Abstract Gastrointestinal perforation (GIP) in preterm neonates may be idiopathic, due to necrotizing enterocolitis (NEC), or mechanical obstruction. The predominant cause of GIP in the neonatal period is NEC. Differential diagnosis with congenital malformations, including mesenteric defects leading to internal hernias, is mandatory if the onset is early. We describe two newborns with trans-mesenteric herniation resulting in GIP, and we discuss the presence of possible additional risk factors such as prematurity and predisposing vascular disruption in connective tissue disorders (Ehlers-Danlos syndrome), twinning, and use of assisted reproductive technologies. These cases prompted us to rev…
Early-stage small-bowel adenocarcinoma: a review of local endoscopic therapy.
2005
Early adenocarcinomas in the small intestine are a rare entity. Most adenocarcinomas in the small intestine are diagnosed at a more advanced stage. After surgical resection, only 3 - 10 % are found in stage T1 and 0 - 3 % in stage Tis (high-grade intraepithelial neoplasia), resulting in an overall 3 - 13 % rate of early-stage small-intestinal adenocarcinomas. The diagnosis of early small-intestinal carcinoma by endoscopy is still very rare, although it will probably improve with the development of new endoscopic techniques. At present there have been only two studies and a few case reports on the treatment of early duodenal carcinoma by endoscopic resection. No major complications such as m…
Spurectomy: A novel modification of non-penetrating deep sclerectomy.
2020
To evaluate the outcomes of a novel modification of the non-penetrating deep sclerectomy (NPDS) approach for glaucoma management called spurectomy.Observational comparative non-randomized retrospective study including 98 glaucomatous eyes of 76 patients operated on with the spurectomy technique consisting of the combination of the excision of the scleral spur with NPDS (groupA). A control group (groupB) including 53 glaucomatous eyes of 43 patients operated on with classical NPDS was also included. Changes in intraocular pressure (IOP) and medications required as well as complications were recorded in a 12-month follow-up.Mean IOP decreased from 25.69±8.11 preoperatively to 15.73±4.16mm Hg …
Empirical calibration of the clumped isotope paleothermometer using calcites of various origins
2014
We present the first universal calibration of the clumped isotope thermometer for calcites of various mineralizing types. These are an eggshell of an ostrich, a tropical bivalve, a brachiopod shell, cold seep carbonate, and three foraminifera samples that grew between 9 and 38 C. CaCO3 was digested at 90 C using a common acid bath. Considering a difference in phosphoric acid fractionation factors between reaction at 25 and 90 C of 0.069& (Guo et al., 2009), the function between growth temperature T and the excess of 13 C– 18 O bonds in the evolved CO2 is expressed by a linear regression between 1/T 2 and absolute D47 (R 2 = 0.9915):
Il progetto di Juvarra per la scala di Palazzo Spadafora a Messina, analisi e ricostruzione digitale
2017
The project by Juvarra for the stair hall of Palazzo Spadafora in Messina, analysis and digital reconstruction This paper presents the results of an historical, architectural and geometrical study on the project by Filippo Juvarra for the stair hall of Palazzo Spadafora in Messina. Some drawings describing the project are today part of different album by Filippo Juvarra preserved in New York and Parigi and show different versions of the stair hall. Although conceived in the first part of Juvarra's career, in 1705, the complex project for Palazzo Spadafora is characterized by originality and sperimentalism, expecially in relation to the panorama of central and southern Italy in the first hal…
