Cellular pathology 1 - Essay Example The eggs of  E. vermicularis which can be seen in the picture are roughly 25 x 60 um in size. The organism has a thin shell and one of the sides is compressed. The eggs and shell of organism have taken up the pink dye which makes them recognizable. The presence of E. vermicularis in the appendix can give the symptoms of acute appendicitis (Wiebe, 1991, p.g. 336). The appendix is a vestigial organ present in the human body. The inflammation of this organ leads to appendicitis. Acute appendicitis is one of most common diseases that lead to inflammation of the gastrointestinal tract. Acute appendicitis is caused due to the obstruction of the lumen, diminished blood supply, pinworm infections caused by Enterobius vermicularis, bacterial infections or due to ischemic damage to mucosal lining of organ (Becker and Hofler, 2002, pg.777). The best described pathogenesis of appendicitis is an obstruction in the appendiceal lumen. The obstruction can be due to lodging of foreign body, lymphoid hyperplasia, fecolith or tumours. The pathogenesis of appendicitis can be understood by the course that the disease takes. In the primary stage, there is obstruction of the lumen which causes accumulation of fluid leading to elevation of intralumin al pressure and lastly resulting in distension of lumina. Suppurative appendicitis occurs due to increased intraluminal pressure which increases the capillary perfusion leading to venous obstruction and hence causing arterial compromise. These crucial events lead to ischemia of the mucosal surface and allow bacterial infestation. As the disease progresses, it causes mural infection which is characterized by oedematous thickening of the appendicular walls. When observed grossly the appendix appears hyperaemic and enlarged. If this progressive condition is not managed surgically it may lead to perforation and gangrene. Gangrenous appendicitis may present as friable serosa with green or black discoloration. If

The US Involvement In The Iraq War - Case Study Example The basic point underscored in most analyses is the fact that the US intervention in Iraq was not based on justifiable grounds and, therefore, constitutes an act of aggression and interference. The US employed numerous tactics to justify the invasion through the assertion that Iraq was a threat to its security and that of the entire world. The assertion that Hussein’s regime possessed actual nuclear weapons was, perhaps, the best approach used by the United States in justifying the attack on the Gulf country. Therefore, the perceived threat of Saddam’s regime on global peace and security was at the heart of the justification of the US intervention in the Gulf conflict that resulted into the ousting of Saddam Hussein and his regime (Murphy 45). However, the unwarranted US involvement became a reality soon after the conclusion of the war; when it became apparent that Saddam’s threat to global society and safety was exaggerated to achieve a secret plan to overthrow his regime. There were no actual nuclear weapons found within the nation after the war. Therefore, to great extent, the US intervention was not justified as Iraq was not a threat to harmony, safety, and strength of America and the rest of the world. Background During the time when the intervention in Iraq was being prepared, the US government administrators and establishment pundits became self-proclaimed Middle East historians vigorously exposing the facts of Saddam Hussein's crimes – many were real, though some were simply imagined (Cimbala and Foster 33). Nevertheless, these same experts studiously shunned examining the well-detailed history of American and British actions – and crimes – concerning Iraq and its citizens.
