Chlamydia pneumoniae infection and risk for lung cancer.

Background: We evaluated the relationship of Chlamydia pneumoniae infection with prospective lung cancer risk using traditional serologic markers [microimmunoflourescence (MIF) IgG and IgA antibodies] and Chlamydia heat shock protein-60 (CHSP-60) antibodies, a marker for chronic chlamydial infection.

Methods: We conducted a nested case-control study (593 lung cancers and 671 controls) within the screening arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (N = 77,464). Controls were matched to cases by age, sex, randomization year, follow-up time, and smoking (pack-years of smoking, time since quitting).

Airway complication following functional endoscopic sinus surgery.

Difficulty breathing after upper airway surgery requires immediate evaluation and treatment. We present a case of airway compromise after sinus surgery due to edema of the uvula. The patient was admitted for observation overnight and discharged the next day.
