Low-grade appendiceal mucinous neoplasm (LAMN) is a rare malignancy and found in less than 0.3% of appendectomy specimens. Patients with LAMN can present abdominal pain mimic clinically as appendicitis, intussusception or obstruction, hence high clinical suspicion needed for correct diagnosis management. The exact nature nomenclature these tumors when they disseminate into the peritoneum contro...
In this appendix, we state a number of preliminary results that will be used in the proofs of the four theorems in the main text. Detailed proofs of the results listed below may be found in Appendix C below. The proofs of the main results are given in Appendix B. The proof of Theorem 4.1 uses Lemmas A.1 and A.2 below. Theorems 5.1 and 5.2 use Lemmas A.3–A.12, A.14, A.15, Theorem A.2, and Lemmas...
CONTEXT Low-grade appendiceal mucinous neoplasm (LAMN) and appendiceal adenocarcinoma are known to cause the majority of pseudomyxoma peritonei (PMP, i.e. mucinous ascites); however, recognition and proper classification of these neoplasms can be difficult despite established diagnostic criteria. OBJECTIVE To determine the pathological diagnostic concordance for appendix neoplasia and related...
Thank you for republishing the landmark paper by Cornfield et al., which the late George Comstock felt should be read by all epidemiologists at least once per year. Of the many innovative aspects for which this paper is praised, we would like to add here one that is rarely mentioned. Appendix B of the paper provides the algebraic proof of an important property of risk ratios described in the bo...
Lemma 11 If {〈θ1, e1〉, . . . , 〈θk, ek〉} {〈θ1, e1〉, . . . , 〈θk, ek〉} according to the semantics of Figure 3, the set of trails {〈θ1, ρ1〉, . . . , 〈θk, ρk〉} is committable, and P is a set of search threads, each with a thread identifier in {θ1, . . . , θk}, then {〈θ1, e1, ρ1〉, . . . , 〈θk, ek, ρk〉}]P − → {〈θ1, e1, ρ1〉, . . . , 〈θk, ek, ρk〉}]P ′ according to the semantics of Figure 9, the set of...
When a bulging appendiceal orifice is observed during surveillance colonoscopy, the possibility of appendiceal mucocele must be considered. Appendiceal mucocele is a rare group of lesions characterized by mucinous distension of the appendiceal lumen with the dangerous potential to rupture, resulting in the development of pseudomyxoma peritonei. Early recognition and diagnosis of appendiceal muc...
Appendiceal diverticulosis is a rare condition. Herein reported is a case of appendiceal diverticulosis and diverticulitis clinically masquerading as appendiceal carcinoma. A 62-year-old woman presented with abdominal pain. US and CT showed a tumor measuring 5 × 4 × 4 cm in vermiform appendix. Colon endoscopy showed mucosal elevation and irregularity in the orifice of vermiform appendix. A biop...
A. Addendum to Lemma 1: There are two cases depending on whether one of the firms dominates the market. The case where no firm dominates the market is described in Lemma 1. The following table states the equilibrium prices and profits when one of the firms dominates the market. We describe the equilibrium only when Firm 1 dominates the market for (T, T),(CU, CU) and (CM, CM) as the results are ...
BACKGROUND Some epithelial neoplasms of the appendix, including low-grade appendiceal mucinous neoplasm and adenocarcinoma, can result in pseudomyxoma peritonei (PMP). Little is known about the mutational spectra of these tumor types and whether mutations may be of clinical significance with respect to therapeutic selection. In this study, we identified somatic mutations using the Ion Torrent A...
