Serum Specific Antibodies Do Not Seem to Have an Additional Role in the Diagnosis of Hypersensitivity Pneumonitis.

Background: We aimed to investigate the contribution of serum IgG testing to the history of exposure in the diagnosis of fibrotic hypersensitivity pneumonitis.

Methods: A single-center, retrospective, cross-sectional study including 63 patients pathologically diagnosed with fibrotic hypersensitivity pneumonitis in line with the guidelines of the American Thoracic Society. Descriptive statistics were presented and Kappa statistic was performed to evaluate the compatibility between panel and the history of exposure.

Is appendectomy always the adequate treatment? Clinical manifestations of isolated actinomycosis in appendix.

Isolated appendiceal actinomycosis is a rare chronic progressive suppurative infection. Causative agent in humans is gram-positive saprophytic an- aerobic bacteria, Actinomyces Israelii. Herein, it was aimed to present a case of acute appendicitis that developed in a 54-year-old female due to isolated appendiceal actinomycosis.

The relationship between diverticula and low-grade mucinous neoplasm of the appendix. Does the diverticulum play a role in the development of periappendicular mucin deposition or pseudomyxoma peritonei?

Prevalences of diverticulum and low-grade mucinous neoplasm (LGMN) were reported as 0.04-2% and less than 1% in the appendix. In this study, the frequency of diverticulum in LGMN cases, the relationship between diverticula and periappendicular mucin, and the possible role of diverticula in pseudomyxoma peritonei pathogenesis were researched.
