    Omental actinomycosis imitating a foreign body infection.
    Z Gastroenterol 2017 Jul 14;55(7):675-678. Epub 2017 Jul 14.
    Actinomycosis is a rare chronic disease caused by a group of anaerobic Gram-positive bacteria that colonize the mouth, colon, and urogenital tract. Infection involving the cervicofacial area is the most common clinical presentation, followed by that of the pelvic and thoracic areas. The preoperative diagnosis of abdominal actinomycosis is difficult because the condition can be easily confused with malignancy, tuberculosis, or other inflammatory diseases. Read More

    Rev Mal Respir 2017 Jun 5;34(6):661-671. Epub 2017 Jul 5.
    Service de microbiologie, unité mobile de microbiologie clinique, hôpital européen Georges-Pompidou, Assistance publique-Hôpitaux de Paris, 20, rue Leblanc, 75015 Paris, France; Université Paris Descartes, 75006 Paris, France. Electronic address:
    Introduction: Pneumonia caused by slow-growing bacteria is rare but sometimes severe.

    State Of The Art: These infections share many similarities such as several differential diagnoses, difficulties to identify the pathogen, the importance of involving the microbiologist in the diagnostic investigation and the need for prolonged antibiotic treatment. However, major differences distinguish them: Nocardia and Rhodococcus infect mainly immunocompromised patients while actinomycosis also concerns immunocompetent patients; the severity of nocardioses is related to their hematogenous spread while locoregional extension by contiguity makes the gravity of actinomycosis.

    Autops Case Rep 2017 Jan-Mar;7(1):43-47. Epub 2017 Mar 30.
    Division of Surgery - Hospital Universitário - Universidade de São Paulo, São Paulo/SP - Brazil.
    Actinomycosis is a chronic or subacute bacterial infection characterized by large abscess formation, caused mainly by the gram-positive non-acid-fast, anaerobic, or microaerophilic/capnophilic, obligate parasites bacteria from the Actinomyces genus. Although pelvic inflammatory disease is an entity associated with the longstanding use of intrauterine devices (IUDs), actinomycosis is not one of the most frequent infections associated with IUDs. We present the case of a 43-year-old female patient who was referred to the emergency facility because of a 20-day history of abdominal pain with signs of peritoneal irritation. Read More

    Department of Plastic and Reconstructive Surgery, College of Medicine, The Catholic University of Korea, Seoul, Korea.
    Actinomycosis, an infectious bacterial disease caused by Actinomyces species, is very rare and is characterized by contiguous spreading, subacute to chronic granulomatous inflammation and the formation of multiple abscesses and sinus tracts that may discharge sulfur granules. Actinomycosis that presents on the skin without endogenous origin is called primary cutaneous actinomycosis, and the occurrence and treatment of primary cutaneous actinomycosis is rarely reported.

    Director of MFM Fellowship, Department of Obstetrics and Gynecology, Madigan Army Medical Center, Tacoma, WA.
    Importance: Actinomyces is commonly found in many areas of the body where it derives a benefit without harming the host. When it does infect the host during pregnancy, is that infection a threat to the obstetric patient and does that infection cause adverse pregnancy outcomes?

    Objective: The aim of this study was to review what is known about Actinomyces infections and the impact of an Actinomyces infection on pregnancy outcomes.

    Evidence Acquisition: A PubMed search was undertaken with the search years unlimited to April 1, 2016, and restricted to articles in English. Read More
