科学领域:
- 过敏和免疫学 过敏和免疫学
- 胃肠病学 胃肠病学
- 手术病理学手术病理学
背景情况:
- 急性尾炎 (AA) 是最常见的手术紧急情况,但其病因尚不清楚.
- 新出现的证据表明,AA病理生理学中有一种过敏成分,涉及巨细胞和Th2免疫反应.
- 介导物,如组胺,血清素和酶,都与过敏反应有关.
研究的目的:
- 研究巨细胞媒介在急性尾炎中的作用.
- 测量AA患者和对照患者的尾洗液 (ALF) 和血清中的胰岛素,血清和酸酶度.
- 探索这些介质的诊断和差异诊断潜力.
主要方法:

Appendicitis-I: Introduction
145
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Acute Pancreatitis II: Clinical Manifestations and Management
124
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
