    Actinomyces in Pregnancy: A Review of the Literature.
    Obstet Gynecol Surv 2017 Apr;72(4):242-247
    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

    Sporadic actinomycosis of the hip complicated by Central Nervous System infection.
    J Pak Med Assoc 2017 Apr;67(4):637-640
    Department of Internal Medicine, Shifa International Hospital, Islamabad, Pakistan.
    Actinomycosis is caused by the Gram positive filamentous Actinomyces bacterial species that are normal commensals of the oral cavity. Due to their low virulence, disease is rare in the immune competent patient. Although it may afflict any system in the body, involvement of the musculoskeletal system is uncommon. Read More

    Destruction of the C2 Body due to Cervical Actinomycosis: Connection between Spinal Epidural Abscess and Retropharyngeal Abscess.
    Korean J Spine 2017 Mar 31;14(1):20-22. Epub 2017 Mar 31.
    Department of Neurosurgery, Chosun University College of Medicine, Gwangju, Korea.
    Human actinomycosis with involvement of the spine is a rare condition, with only a limited number of case reports published. To the best of our knowledge, no cases have been reported of epidural abscess causing destruction of the C2 body, bringing about a direct connection between spinal epidural and retropharyngeal abscesses. Here, we present such a case that occurred after acupuncture, and we review the relevant literature. Read More

    Can Surgery Be Avoided? Exclusive Antibiotic Treatment for Pelvic Actinomycosis.
    Case Rep Obstet Gynecol 2017 16;2017:2907135. Epub 2017 Feb 16.
    Department of Obstetrics and Gynecology, University of Missouri Kansas City, Kansas City, MO, USA.

    Unusual Behavior of a Posttraumatic Scar: Craniofacial Actinomycosis.
    Wounds 2017 Jan;29(1):E1-E4
    Division of Plastic Surgery, Sir Gangaram Hospital, New Delhi, India.
    Actinomycosis is a chronic suppurative granulomatous infection most commonly involving the cervicofacial region. Clinical diagnosis is usually difficult, and fine-needle aspiration cytology or imaging studies are usually unhelpful in diagnosing actinomycosis. Definitive diagnosis is based on the histopathological examination of a tissue biopsy. Read More

    Facial Actinomycosis Mimicking a Cutaneous Tumor.
    Wounds 2017 Jan;29(1):10-13
    Pamukkale University Hospital, Department of Plastic, Reconstructive and Aesthetic Surgery, Denizli, Turkey.
    Actinomycosis is a chronic granulomatous infection that commonly occurs in the cervicofacial region. Although Actinomcyes is an element of the normal oral flora, infections of the facial skin are very rare because of the entirely endogenous habitation of the organism. The authors report a case of facial actinomycosis, which mimicked a cutaneous tumor both clinically and surgically in a 44-year-old woman with chronic renal failure and Hepatitis C viral infection.

    Cervicofacial Primary Cutaneous Actinomycosis: Surgical Treatment for Complete Remission of the Disease.
    J Craniofac Surg 2017 Jan 30. Epub 2017 Jan 30.
    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. This report describes the treatment of primary cervicofacial actinomycosis with a literature review, and emphasizes the importance of surgical option for complete remission of the disease. Read More

    Assessing Fifty Years of General Health Surveillance of Roe Deer in Switzerland: A Retrospective Analysis of Necropsy Reports.
    PLoS One 2017 19;12(1):e0170338. Epub 2017 Jan 19.
    Centre for Fish and Wildlife Health, Vetsuisse Faculty, University of Bern, Bern, Switzerland.
    General wildlife health surveillance is a valuable source of information on the causes of mortality, disease susceptibility and pathology of the investigated hosts and it is considered to be an essential component of early warning systems. However, the representativeness of data from such surveillance programs is known to be limited by numerous biases. The roe deer (Capreolus capreolus capreolus) is the most abundant ungulate and a major game species all over Europe. Read More

    Inflammatory and subcutaneous nodules can arise in treated and untreated cases of Whipple disease (WD). The inflammatory immune reconstitution syndrome describes paradoxical clinical inflammatory worsening of a preexisting condition because of a return of immune function. Clinicopathologic examination of 4 patients with WD who presented with erythema nodosum leprosum (ENL)-like lesions and the findings of a systematic review of this phenomenon revealed that ENL-like lesions occurred in predominantly middle-aged male patients who suffered from WD, mostly on the legs.

    a Division of Internal Medicine , Krankenhaus Maria Hilf , Daun , Germany.
    In recent years, it has become apparent that Tropheryma whipplei not only causes a chronic multisystemic infection which is often preceded by arthropathies for many years, well known as 'classical' Whipple's disease, but also clinically becomes manifest with localized organ affections and acute (transient) infections in children. T. whipplei is found ubiquitously in the environment and colonizes in some healthy carriers. Read More
