Abstract: The presence of an intrauterine device (IUD) within the colon is rare. Complications have been reported with IUDs among which uterine perforation. Translocation of IUDs to the uterine cavity, to the bladder and also through the wall of the bowel, and sigmoid colon has been reported. We believe there may be a case that surgeons should know the result of despite being a priori gynaecological complication. This paper reports on a case of colon perforation by an IUD. The IUD is a commonly used reversible birth control method. One of the rare, but potentially serious complication is uterine perforation. In this paper, we report the exceptional case of an asymptomatic IUD translocation to the rectosigmoid colon lumen secondary to uterine perforation. A 31-year-old patient was admitted to the emergency department complaining of proctalgia for one month. Unfortunately, no information was available regarding the IUD insertion procedure. The patient had a delivery fifteen months before. A rectal exploration showed the presence of a foreign body. An X-Ray showed a IUD. CT scan was performed and showed a normal uterus and a metallic piece entering the rectum. This CT scan incidentally revealed the presence of an IUD in the lumen of the rectosigmoid colon (See Figure 1). Removal of the device by means of endoscopic procedure was not performed. The patient underwent a surgical exploration and the IUD was removed from the rectum transanally. The postoperative course was uneventful. Figure 1: IUD is displayed in the rectum (arrow) after perforating the uterus located in front. Uterine perforation is a rarely observed complication. The incidence of IUD perforation ranges from 0.05/1,000 to 13/1,000 [1, 2]. Many authors have recommended that IUDs should be inserted by skilled providers to prevent complications such as uterine perforation [3]. IUD migration is more frequent in women who undergo labour with their IUD in place. In this last situation, due to the reduction in the size of the uterus and thinning of the uterine walls in the postpartum as a result of hypoestrogenemia, the uterus becomes more susceptible to perforation [2]. May be this could have contributed to the perforation in the case presented here. May be this could have been another explanation in our case. Colon perforation is rare but has been described previously [4]. Another location of migration is the bladder because of its close proximity to the uterus [5] or the peritoneal cavity [6]. Other cases have been described as mimicking chronic appendicitis [7]. X-Ray and TVS can be helpful but CT scan

Abstract: Intestinal schistosomiasis as unusual aetiology for acute appendicitis, nowadays a rising disease in western countries. Recent changes in global migration has led to an immigration growth in our scenario, upsurging people coming from endemic areas of schistosomiasis. Schistosomal appendicitis, seldom reported in developed countries, is now an expected incrising entity in our hospitals during the near future. Due to this circumstances, we believe that schistosomiasis should be consider as a rising source for acute appendicitis in western countries. In order to illustrate this point, we present a case of a 45-years-old black man, from Africa, was admitted via A&E because of acute abdominal pain, located in right lower quadrant. Acute appendicitis was suspected, and he underwent laparotomy and appendectomy. Pathological study by microscope revealed a gangrenous appendix with abscesses and parasitic ova into the submucosal layer of the appendix, suggesting Schistosomiasis.

International Journal of Vascular Medicine , 2012, DOI: 10.1155/2012/942512
Abstract: Chylomicron remnants (CMRs) contribute directly to human monocyte activation in vitro, by increasing reactive oxygen species (ROS) production and cell migration. In this study, the effects of the oxidative state of CMR on the degree of monocyte activation was investigated. CMR-like particles (CRLPs) were prepared in three different oxidative states, normal (CRLPs), protected from oxidation by incorporation of the antioxidant, probucol (pCRLPs), or oxidised with CuSO4 (oxCRLPs). Lipid accumulation and ROS production were significantly increased in primary human monocytes incubated with CRLPs, whilst secretion on monocyte chemoattractant protein-1 was reduced, but oxCRLPs had no additional effect. In contrast, pCRLPs were taken up by monocytes to a lesser extent and had no significant effect on ROS or MCP-1 secretion. These studies suggest that the oxidative state of CMRs modulates their stimulation of the activation of peripheral blood human monocytes and that dietary antioxidants may provide some protection against these atherogenic effects. 1. Introduction It is now acknowledged that cardiovascular disease (CVD) is the largest killer in western countries [1]. Atherosclerosis is major cause of CVD, and it has become clear in the past decades that it is a chronic inflammatory disease [2]. Activation of monocytes is an early event in atherogenesis, triggering their adhesion to the endothelium, migration into the arterial intima, and differentiation into macrophages [3–5]. The role of low-density lipoprotein (LDL) in early atherogenesis is also well understood, it accumulates in the developing neointima where it is taken up by macrophages to form foam cells, leading to fatty streak formation, and these effects are greatly enhanced after oxidation of the particles. Oxidized LDL (oxLDL) also stimulates secretion of proinflammatory cytokines, chemokines, and other factors by macrophages, which exacerbates endothelial dysfunction and drives lesion progression [6]. In recent years, however, evidence has accumulated to indicate that lipoproteins of dietary origin are also atherogenic [7, 8]. Lipids from the diet are absorbed in the gut and secreted into lymph in large, triacylglycerol- (TG-) rich lipoproteins called chylomicrons. They pass through the thoracic duct and into the blood where they undergo rapid lipolysis, losing some of their TG to form smaller chylomicron remnants (CMRs), which then deliver the remaining TG, cholesterol, and other lipids to the liver. CMRs have been shown to enter the artery wall as efficiently as LDL and to be retained in the

Schistosomal appendicitis, seldom reported in developed countries, is now an expected incrising entity in our hospitals during the near future. Due to this circumstances, we believe that schistosomiasis should be consider as a rising source for acute appendicitis in western countries. In order to illustrate this point, we present a case of a 45-years-old black man, from Africa, was admitted via A&E because of acute abdominal pain, located in right lower quadrant. Acute appendicitis was suspected, and he underwent laparotomy and appendectomy. Pathological study by microscope revealed a gangrenous appendix with abscesses and parasitic ova into the submucosal layer of the appendix, suggesting Schistosomiasis. Schistosomal appendicitis is rarely reported in developed countries. However, recent changes in global migration have led to an immigration growth, from endemic areas of schistosomiasis, in Western countries. These changes are building a new scenario in which an ascending number of schistosomiasis is expected in our hospitals in the near future. Due to this circumstances, we believe that schistosomiasis was unusual in the past in our environment, nowadays it should be considered in our landscape as a familiar cause for different medical entities, as in our case, for acute appendicitis. Schistosomiasis is the second most prevalent parasitic disease worldwide. More than 200 million people are infected, 120 million are symptomatic, and 20 million suffer from severe disease. An estimated 85% of all cases, and virtually all of the most severe, are concentratedin African countries. Brazil, China, and Yemen are the most affected countries in the Americas, Asia, and the Middle East. Population growth and movement in endemic areas and ecologic changes resulting from increasing use of water for irrigation and electricity generation have contributed to the spread of infection [1]. Bierman and colleagues state that there is a steady rise of imported schistosomiasis cases in industrialized countries, which may reflect both a true increase and raised awareness [2]. TropNetEurope, a group of tropical medicine institutions in Europe, reported more than 800 cases in 2003, mostly from sub-Saharan Africa (T. Jelinek, personal communication, April 2004). Two-thirds concerned immigrants and refugees, and only

Abstract: En une dizaine d'années, le diesel a connu un développement spectaculaire sur les marchés automobile fran ais et européen et pourrait atteindre, en 1995, la moitié des immatriculations de véhicules particuliers en France et le quart en Europe de l'Ouest. Cette situation n'est évidemment pas sans poser de problèmes. Problèmes environnementaux puisque le moteur diesel est une source plus importante d'émissions d'oxydes d'azote et de particules que le convertisseur essence, mais également au niveau de l'industrie du raffinage qui, en France, n'est plus en mesure de satisfaire la demande en gazole. De plus, à compter du 1er octobre 1996, la teneur en soufre du gazole routier ne devra pas excéder 0,05 %, conformément aux nouvelles spécifications européennes. Cette perspective de production de carburants fortement désulfurés va affecter directement l'équilibre en hydrogène de la raffinerie et donc les autoconsommations et les émissions de CO2. L'objectif de cette étude est de mesurer l'impact sur l'environnement d'une réduction de la teneur en soufre des gazoles de 0,3 à 0,05 %. Le bilan est réalisé sur l'ensemble de la filière énergétique, depuis l'extraction du pétrole jusqu'à la combustion du carburant dans le moteur. Les gains et les pertes en termes de pollution locale ou globale sont évalués suivant la nature de l'hydrogène utilisé (oxydation partielle de résidus sous vide ou de charbon, reformage à la vapeur de gaz naturel ou de naphta électrolyse) et la nature de la charge à traiter (gazole straight run ou light cycle oil) lors de l'hydrodésulfuration. Over the past decade, diesel had made large advances in the French and European automobile markets. In 1995, diesel could account for half of all private vehicle registrations in France, and a quarter in Western Europe. This situation inevitably raises a number of problems : environmental problems, because the diesel engine emits more nitrogen oxides and particulates than the gasoline converter, and also because the French refining industry is no longer able to meet domestic demand. Furthermore, starting 1st October 1996, according to the new European specifications, the sulfur content of road diesel must not exceed 0. 05%. This prospect of the production of highly desulfurized motor fuels will directly affect the hydrogen balance of the refinery, and hence self-consumption and C02 emissions. This study is aimed to assess the environemental impact of the reduction of the diesel sulfur content from 0. 3 to 0. 05 %. The review covers the entire energy cycle, from oil extraction to fuel combustion in the e

Abstract: introduction: neuroendocrine tumours of the colon and rectum are infrequent. they are usually undifferentiated, easy to diagnose for the pathologist and are especially aggressive in their clinical behaviour. prognosis is usually poor and they have a high tendency to metastase early. material and methods: we have reviewed our experience in a colorectal unit during a period of six years. patients with neuroendocrine tumours have been reviewed retrospectively. carcinoid tumours have not been included in this study. results: during this period, 2,155 patients have been operated for colorectal cancer and in five patients a neuroendocrine tumour has been found in the specimen. mean age was 66 years, three male and two female. one tumour was located in the caecum, two in the rectum and two in the sigmoid colon. two patients had hepatic metastasis at diagnosis. surgery was performed in all patients and two patients received adjuvant quimiotherapy. a patient died because of post-operative hepatic insufficiency, another at 2 months and another after one year. two patients are still alive after eight months' follow-up. conclusions: neuroendocrine tumours appear to be rare in the colon and rectum. clinical manifestations are not different from standard adenocarcinoma. when these tumours are diagnosed, they have distance disease, as in two of the five cases, related to a poor prognosis for the patient. surgery is the treatment that can offer a greater chance of survival to these patients.
