Three weeks following a toothache, a 56-year-old man developed cough, sputum, fever, and pleuritic chest pain. He had mild periodontal disease and his chest radiographs and chest computed tomographic (CT) scans showed multiple pulmonary nodules. The CT scan strongly suggested septic pulmonary embolism. Aspirated pus from one of the nodules yielded pure growth of Streptococcus intermedius. Lesions resolved with antimicrobial therapy. The usual predisposing factors for septic pulmonary embolism were absent, and, the isolation of S intermedius from the pus, the antecedent toothache, and periodontal disease all suggested the gingiva as the source. We hypothesize that periodontal infection led to bacteremia, seeding of the lungs, and multiple anaerobic pulmonary abscesses, akin to reported instances of infective endocarditis from dental foci without any prior dental procedures. To our knowledge, this presentation of septic pulmonary embolism is unprecedented.

We report two cases of septic pulmonary embolism associated with periodontitis. Chest CT revealed multiple nodular shadows with features characteristic of septic pulmonary embolism in both patients. Both patients had toothache, fever, and chest pain, and showed findings of periodontitis at initial presentation. Antimicrobial agents combined with dental surgery were successful in treatment. While septic pulmonary embolism from the lesions of periodontitis appears to be rare, periodontitis remains important in the differential diagnosis of septic pulmonary embolism.

Over-the-counter cyclooxygenase inhibitors are used to relief fever and various types of acute pain like headache, toothache, earache, sore throat, as well as postoperative and menstrual ones. They are also major ingredients in cold and flu mixtures. Unlike well-known organ toxicological profile, their prenatal toxicity was not fully established. For a long time, acetaminophen was considered as a relatively safe antipyretic and analgesic drug during pregnancy. However, a new data indicate that it may increase the risk of cryptorchidism and asthma during childhood as well as preeclampsia, preterm birth, maternal phlebothrombosis and pulmonary embolism. Contrary to acetaminophen, non-selective cyclooxygenase inhibitors (non-steroidal anti-inflammatory drugs - NSAID; i.e., diclofenac, ibuprofen, naproxen) may induce intrauterine growth retardation, ductus arteriosus constriction with secondary persistent pulmonary hypertension, reduced fetal renal perfusion that led to oligohydramion, prolonged pregnancy as well as increase prevalence of intracranial bleeding in newborns. Furthermore, a higher risk of miscarriage, stillbirth and some congenital malformations (cardiac and diaphragmatic defects, celosomy - gastroschisis and umbilical hernia) was reported for non-selective inhibitors, in particular high doses of acetylsalicylic acid (aspirin).

Dental infection can be an important source for septic pulmonary embolism (SPE), but only a few cases of SPE accompanying dental infection have been reported. The aim of this study was to characterize the clinical features of SPE induced by dental infection. Patients who fulfilled the diagnostic criteria described in the text were recruited in a retrospective fashion. All 9 patients were men, with a median age of 59 years (range:47 to 74 years). Eight patients had chest pain (88.9%), 5 had a preceding toothache (55.6%) and 3 had preceding gingival swelling (33.3%). Blood cultures obtained from 7 patients were negative. Periodontitis was found in all of the cases, periapical periodontitis in 5 cases, and gingival abscess in 3 cases. The median duration of hospitalization was 15 days, and symptoms were mild in some cases. In addition to antimicrobial therapy, tooth extraction was performed in 3 cases, tooth scaling in 6. SPE induced by dental infection has prominent clinical characteristics such as male preponderance, chest pain, preceding toothache, and mild clinical course.
